Ministry of Agriculture and Rural Affairs: No unit or individual may introduce, release or discard alien species without authorization.

  According to the website of the Ministry of Agriculture and Rural Affairs, recently, the Ministry of Agriculture and Rural Affairs, the Ministry of Natural Resources, the Ministry of Ecology and Environment and the General Administration of Customs jointly issued the Measures for the Administration of Alien Invasive Species (hereinafter referred to as the Measures). The reporter interviewed the relevant person in charge of the Department of Science, Technology and Education of the Ministry of Agriculture and Rural Affairs on relevant issues.

  Q: Please tell us about the background of the promulgation of the Measures.

  A:The prevention and control of alien species invasion is related to national food security, biological security and ecological security. In recent years, with the increasingly frequent commodity trade and personnel exchanges in China, the diffusion routes of alien invasive species are more diversified and concealed. Most invasive species can find suitable living environment in China. Once colonized, it is difficult to eradicate them completely, which seriously affects the ecological environment of the invasive areas and damages the sustainable development and biodiversity of agriculture, forestry, animal husbandry and fishery. The Biosafety Law of People’s Republic of China (PRC), which was promulgated on October 17th, 2020 and came into effect on April 15th, 2021, clearly stipulates that "the state shall strengthen the prevention and response to the invasion of alien species and protect biodiversity. The competent department of agriculture and rural areas in the State Council shall, jointly with other relevant departments in the State Council, formulate a list of alien invasive species and management measures ". In order to effectively strengthen the management of alien invasive species, the Ministry of Agriculture and Rural Affairs, together with the Ministry of Natural Resources, the Ministry of Ecology and Environment and the General Administration of Customs, systematically sorted out the relevant legislation at home and abroad, conducted in-depth expert discussions and field research, and widely listened to the opinions of relevant departments, industry experts and the public. On this basis, the Measures were studied and formulated.

  Q: What is the overall consideration of the Measures for strengthening the whole chain management of alien invasive species and improving the responsibility mechanism?

  answerAlien invasive species refer to alien species that have been introduced and colonized and brought threats or harms to ecosystems, habitats and species, and affected the ecological environment in China, damaging the sustainable development and biodiversity of agriculture, forestry, animal husbandry and fishery. The general consideration of strengthening the management of alien invasive species is to adhere to risk prevention, source control, comprehensive management, coordination and public participation, highlight key areas and key links, establish and improve management systems, strengthen joint prevention and control, group prevention and group treatment, and comprehensively improve the management level of alien invasive species.The first is to strengthen the supervision of the whole chain.The "Measures" stipulate the prevention, monitoring and early warning, treatment and restoration of alien invasive species, further strengthen the prevention and control of alien invasive species from all aspects, and build a full chain prevention and control system.The second is to clarify the division of responsibilities.The Ministry of Agriculture and Rural Affairs shall, jointly with relevant departments, establish an inter-ministerial coordination mechanism for the prevention and control of alien invasive species, and the local people’s governments at or above the county level shall be responsible for the prevention and control of alien invasive species in their respective administrative areas according to law, and the relevant departments of the local people’s governments at or above the county level shall carry out prevention and control work according to the division of responsibilities.The third is to guide public participation.Strengthen publicity, education and popularization of science, encourage and guide the public to participate in prevention and control work according to law, and no unit or individual may introduce, release or discard alien species without approval.

  Q: What are the specific requirements for source prevention in the Measures?

  A: "The Measures put forward clear requirements for strengthening source prevention mainly from three aspects.The first is to standardize the introduction management.Where exotic species such as crops, forest and grass seeds and seedlings, and aquatic products are introduced from abroad due to special needs such as variety cultivation, import approval and quarantine approval shall be handled according to the examination and approval authority. If it is introduced for the first time, the importing unit shall conduct risk analysis and submit a risk assessment report to the examination and approval department.The second is to strengthen port prevention and control.The customs shall strengthen port prevention and control, crack down on illegal activities such as illegal introduction, carrying, delivery and smuggling of alien species, and dispose of the discovered alien invasive species according to law.The third is to strengthen domestic quarantine.The competent departments of agriculture, rural areas, forestry and grassland at or above the county level shall strengthen the quarantine supervision over the trans-regional transportation of crops, forest and grass seeds and seedlings, plant products, aquatic seedlings, etc., so as to prevent the spread of alien invasive species.

  Q: How does the Measures stipulate the monitoring and early warning of alien invasive species?

  answerIn order to strengthen the monitoring and early warning of alien invasive species and grasp the status of alien invasive species in time, the Measures mainly make three provisions.The first is to carry out investigation and monitoring.Establish a general survey and monitoring system for alien invasive species, organize a national survey every ten years, build a national monitoring network for alien invasive species, and carry out regular monitoring.The second is to issue early warning and forecast.The competent departments of agriculture, rural areas, forestry and grassland at or above the provincial level and the customs shall strengthen the sharing of monitoring information, analyze and judge the occurrence and spread trend of alien invasive species, issue early warning and forecast in time, and guide the prevention and control.The third is to standardize information release.The overall situation of alien invasive species in China is uniformly released by the relevant departments of the Ministry of Agriculture and Rural Affairs. The occurrence of alien invasive species in related fields shall be released by the relevant departments of the State Council according to their duties and powers. Provincial agricultural and rural authorities, in consultation with relevant departments, uniformly release the situation of alien invasive species in their respective administrative areas.

  Q: What are the clear provisions of the Measures on the implementation of governance restoration?

  A:In order to vigorously promote the management and restoration of alien invasive species, the Measures stipulate that the Ministry of Agriculture and Rural Affairs, the Ministry of Natural Resources, the Ministry of Ecology and Environment and National Forestry and Grassland Administration should study and formulate strategies and measures for the prevention and control of alien invasive species according to their division of responsibilities, and all localities should formulate prevention and control plans and implement prevention and control measures in light of actual conditions.Control of alien invasive plants,According to the actual situation, measures such as manual uprooting, mechanical uprooting, spraying green chemicals and releasing natural enemies can be taken in the key growth periods such as seedling stage, flowering stage or fruiting stage.Control of alien invasive pests and diseases,Measures such as selecting pest-resistant varieties, pre-treating seedlings, physical removal, chemical elimination and biological control should be taken to effectively prevent the spread of pests and diseases.Control of alien invasive aquatic animals,Measures such as targeted fishing should be taken to prevent its further spread.Besides,The "Measures" require that measures such as planting native plants and releasing local species should be taken according to local conditions to restore the ecosystem in the area where alien invasive species occur.

  Q: The Measures will be implemented on August 1, 2022. How to implement them in the next step?

  answerThe Ministry of Agriculture and Rural Affairs, together with relevant departments, will earnestly publicize and implement the Measures and strengthen the management of alien invasive species. Focus on three aspects of work.First, do a good job in publicizing and interpreting the Measures.Take a combination of online and offline, organize training for managers at all levels, do a good job in interpreting the provisions of the Measures, and improve the ability of supervision and management according to law. Production and distribution of popular science propaganda materials, to enhance public awareness of prevention and control.The second is to promote the general survey of alien invasive species.In farmland, fishing waters, forests, grasslands, wetlands, major ports of entry and other areas, speed up the implementation of the general survey of alien invasive species, and find out the species, quantity, distribution range and harm degree of alien invasive species in China.The third is to strengthen the management of alien invasive species.Formulate prevention and control guidelines by classification and species, clarify the key periods, key areas and main measures for prevention and control, strengthen policy support and technical guidance for governance, and take comprehensive measures to effectively control alien invasive species.

Key extension, big secret making, fast free application, self-determined time.

This article was first published in the film industry. Welcome to pay attention (WeChat search filmmore).

     The news of the postponement of popular blockbusters is endless. From last summer’s troika to this year’s Spring Festival’s three strong films, the screening time has been extended, and the box office champion of Chinese films has been postponed for three months at once. In the eyes of the general audience, the postponement means that it can be seen in the cinema one month after the film is released. However, in the eyes of the industry, the specific process of key extension is the most important. Why can a movie be released for as long as four months? Is the existence of this mechanism reasonable? This article will take you through all aspects of key extension.

 

What is the key extension? You can’t show a movie until you have a key. You don’t have to pay for an extension.

 

    For the general audience, the word key is unfamiliar. What is a key? This should start with the film screening. The movie will be made into a copy, and it needs to be connected to the server before it can be read. The key is similar to the activation code, which allows the server to successfully read the movie in the copy. At this time, the projector can play the movie, and it cannot be shown without the key.

 

    So where did the key come from? According to a senior person who has been engaged in distribution for many years, most of the current keys are made by China Film Digital Film Development Co., Ltd. (hereinafter referred to as China Digital Film Development Co., Ltd.) and Huaxia Film Distribution Co., Ltd. (hereinafter referred to as China). These two companies actually play the role of agents between the issuer and the cinema, and the issuer can save manpower and material resources through their communication and settlement with the cinema. Therefore, we will see the names of these two companies in many documents with extended keys.

 

    After the key is made, it will be uploaded to the network and downloaded by each theater. The validity period of the key is one month, that is, we often say that the film screening period is one month. After the expiration, the cinema server will no longer be able to read the movies in the copy. At this time, if you still want to show, you need to postpone the key.

 

    When a movie wants to be postponed, do you still have to pay a fee? The answer is no, Zhu Dawei, vice president of Stellar Pictures, Qin Wei, vice president of Beijing An Shi Ying Na Film Distribution Company (hereinafter referred to as An Shi Ying Na) and many other people in the industry have confirmed this, but they don’t need to pay for the extension of the key.

 

Is there a standard for key extension? Domestic films are flexible to operate and imported films are difficult to judge.

 

    Since it doesn’t cost money to extend the key, isn’t it an extension if you want? You can postpone it at any time or for as long as you want. The answer is still no.

 

    According to the distributor who has operated many imported films, it is true that there is no explicit stipulation in the mainland about which films can be postponed and which ones can’t. Generally speaking, domestic films are very flexible in operation. "Just tell the distribution company, such as China Digital, through them to tell the cinemas that we have extended the key, and everyone can still use it. That’s it." Of course, the so-called "let me know" actually needs to be presented in written form, but domestic films will basically not encounter any problems and there is no limit.

 

    But this is not the case with imported films. Zhu Dawei, vice president of Stellar Films, said that imported films need to apply to the Film Bureau for extension. According to the senior distributor, after the imported film is submitted, it depends on whether it will be rejected.

 

    There are indeed many domestic films and some imported films in the history of mainland film. For example, the one in 2010, which was released on January 4, was postponed until March 14, when it was released for more than two months, is very rare in imported films. Released on April 10, 2012, it was extended for another month when the key expired, and finally the box office exceeded 1 billion.

 

    Looking back carefully, most of the key extension time is within one month, and it is really surprising that the Mermaid has been extended for three months at once. Is it arbitrary to extend the time? The answer this time is yes.

 

Is there a time limit for extension? The film is completely independent, and most of them do not exceed one month.

 

    After the key expires, how long you want to extend it is really up to the film, whether it is a week or a month, and no one interferes. The three popular films in the Spring Festival were postponed for one month, 12 days and released on March 20th, except Mermaid, which was postponed for three months. At present, there is no specific extension, and there is no strict regulation on when to apply for an extension.

 

    Qin Wei, vice president of Ann Shi Ying, told us that in theory, five working days before the start of the extension, they would communicate with the key maker who often cooperated, but there was no big problem earlier or later, and the time was more flexible. Moreover, the extension notice of "Journey to the West’s Monkey King Thrice Defeats the Skeleton Demon" released by Ann Shi Ying was issued on February 18. The reason why the extension notice was released ten days after the film was released was because both the film producer and the publisher had enough confidence. "We felt that the reputation was good and we wanted to take a long-term screening from the beginning."

 

    After the issuance direction of China Digital or Huaxia proposed to extend the key, the two companies completed it relatively quickly. "Now, if you follow the process, you can go down in two days. In fact, China Digital also has a competitive relationship with China, and everyone has to compete for services." The veteran of the distribution industry said. According to Qin Wei, sometimes it doesn’t take two days. "It can be made in half a day, which is faster."

Interior environment becomes a hot spot of automobile quality complaints. Experts call for the introduction of mandatory standards for interior pollution as soon as possible.

  According to the latest data of "Analysis Report on Indoor Air Quality Problems" released by Chezhi. com, from 2010 to August 2019, consumers complained about the odor inside the car for 9,300 times. From January to August this year alone, the number of related complaints reached 1,646 times. It is predicted that the number of complaints in the whole year will reach a record high.

  "The lack of relevant control standards in the interior environment, lack of legal basis and lack of supervision have led to increasing air quality problems in the car." Become the consensus of experts. Recently, at the "Third March 15th Automobile Consumption Forum and Symposium on Promoting the Issuance of Compulsory Standards for Indoor Pollution" sponsored by china law society Consumer Law Research Association and co-organized by Chezhi. com, participants in drafting relevant standards for indoor environment, environmental experts, legal professionals, scholars and senior experts in the automobile industry had in-depth discussions on the existing problems of indoor air quality, the reasons for the delay in the introduction of compulsory standards, and how consumers should safeguard their rights and interests.

  The smell inside the car has become one of the hot issues of automobile quality.

  According to a folk statistic in 2017, there are more than 4,600 models on sale in China automobile market. Combined with the faster and faster iteration speed of models, there will be more models on sale at present. According to the data released by the Ministry of Public Security, as of June this year, the number of cars in China has reached 250 million.

  With the rapid improvement of modernization, people’s dependence on vehicles has become increasingly obvious. In addition to homes and workplaces, vehicles have become one of the main places where human beings stay. On the other hand, in order to meet consumers’ requirements for automobile comfort, manufacturers constantly improve the structural design of automobile interiors, and use more new technologies, new materials and new processes, especially the extensive application of nonmetallic materials and adhesives, which leads to the accumulation of pollutants in automobiles and harms human health. With the continuous improvement of the public’s environmental awareness and self-protection awareness, the public has higher expectations and stricter requirements for the air quality in the car, which is closely related to human health. In recent years, the environmental problems in the car have attracted much attention.

  The reporter noted that the car quality network data shows that the odor inside the car has become one of the top ten car quality hot issues from 2010 to August this year. Zhang Yue, director of the Automotive Quality Network Research Institute, even pointed out that consumers’ concern about the interior environment will reach its peak this year, which will be followed by advocating the elimination of pollution hazards to automobile enterprises with a "death-like attitude".

  "vehicle air pollution’s problem, a recommended standard before, but there is no mandatory standard, so what’s the problem? After consumers encounter problems, there is a basis for unresolved disputes, and the recommendation standard can not be implemented. " According to Guangsheng Song, director of the National Indoor Interior Environment and Environmental Protection Product Quality Supervision and Inspection Center, although some people in the industry paid attention to the indoor air quality in 2003, with the blowout development of the automobile market in previous years, the purpose of formulating the relevant standards for indoor air quality has changed from the initial prevention of shoddy automobile products to the stage of meeting consumers’ demands for the safe driving environment of automobile products.

  "We call for and look forward to the introduction of relevant mandatory national standards as soon as possible to effectively strengthen consumer protection." Chen Jian, director of the legal and theoretical research department of the China Consumers Association, said that the right to safety is the first right of consumers. In recent years, consumers have paid more and more attention to the air quality in cars, and related consumer disputes are more prominent. It is suggested that starting from the protection of consumers’ safety rights, we should keep pace with the times to study automotive materials and formulate standard limits. In order to protect consumers’ rights, we should improve the detection methods of in-use vehicles and promote the convenience of identification. Starting from standardizing the use of materials, the filing system of environmental protection report for vehicle materials is established. It is hoped that enterprises in the industry will issue an indoor air quality test report while selling cars to protect consumers’ right to know and choose.

  It is understood that after the implementation of the "Guide for Air Quality Assessment in Passenger Cars" (GB/T 27630-2011) issued by the Ministry of Environmental Protection, the products launched by vehicle manufacturers have improved to some extent through the monitoring of China Consumers Association, but the effect is limited. Around 2017, consumers’ concern about the air quality inside the car peaked again, which also shows that consumers are paying more and more attention to the possible violation of their safety rights caused by this hidden danger.

  In-vehicle environmental detection is controversial, and it is difficult for consumers to defend their rights.

  Heshan, president of china law society Consumer Law Research Association, said that as far as automobile products are concerned, in some cases of rights protection, there is a dispute about whether they are luxury goods or consumer goods. In this case, when consumers encounter vehicle air pollution, the detection resistance becomes greater. He believes that once consumers think that their rights and interests are damaged, they should still advocate that family cars are also consumer goods and use relevant laws to safeguard their legitimate rights and interests.

  Specific to the identification and evaluation links and standards, Jian Chen frankly said that there are not many institutions with testing qualifications at present, and the testing costs are high, and some institutions do not issue testing reports to individuals, etc., which are all technical difficulties when consumers protect their rights. Another major factor affecting rights protection is how to prove the relationship between the car environment and the consumer’s illness. This requires relevant departments to carry out relevant epidemiological investigations and follow-up studies.

  In fact, another important factor that makes it difficult for consumers to defend their rights is the lack of mandatory standards. It is understood that the Guide for Air Quality Assessment in Passenger Cars (GB/T 27630-2011) issued by the Ministry of Environmental Protection and the Sampling and Determination Method of Volatile Organic Compounds and Aldehydes and Ketones in Cars (HJT 400-2007) issued by the State Environmental Protection Administration are authoritative testing standards and methods for evaluating air quality in cars. In the former, eight detection substances, including benzene, toluene, xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde and acrolein, and their limit values are specified.

  However, the former, as a recommended standard, cannot force all enterprises to provide qualified automobile products. In 2016, the Ministry of Environmental Protection issued the "Guidelines for the Evaluation of Air Quality in Passenger Cars" (draft for comments), and proposed that the recommended standard would be upgraded to a mandatory standard, and it is planned to be implemented on January 1, 2017, making it clear that all newly-finalized sales vehicles must meet the requirements of this standard. However, after two years, the mandatory standard has repeatedly broken its promise.

  All kinds of gaps between consumers and access to in-vehicle air quality testing have made it difficult for consumers to take legal proceedings to protect their rights. "In more than a dozen judicial cases of air quality in cars I have studied, no consumer has won the lawsuit." Jiang Suhua, a lawyer of Beijing Yingke Law Firm, bluntly said that this is not to say that consumers can’t win this kind of lawsuit, but there are too many links involved, and a slight negligence may lead to a loss of one link.

  In addition, another difficulty in indoor air quality detection lies in the diversity of pollutant sources. Zhang Jinliang, a researcher at china environmental science Research Institute, believes that the air pollution sources in cars can be basically divided into interior decoration and decoration. According to Zhang Yue, the direct pollution sources of indoor air quality are mainly the dashboard assembly, door trim panel, carpet, ceiling, automotive wiring harness and seat assembly. In addition to the accessories installed by consumers, the pollution sources may also come from the outside of the car and the substances emitted by the car.

  Improving the air quality inside the car requires multi-party participation.

  Jiang Jun, the propaganda director of the C-ECAP Management Center of China Automotive Technology and Research Center Co., Ltd., pointed out that after testing more than 700 models on the market, the project team found that the proportion of models that can meet the relevant provisions in the Guide for Air Quality Evaluation in Passenger Cars (GB/T 27630-2011) is basically 50%, which means that half of the models still fail to meet the recommended standards, and there is still room for improvement in the overall industry level.

  The reality is that some models with substandard air inside the car are still in circulation in the market. According to the research data of Gaode Map, taking Beijing as an example, each person spends 174 hours on commuting congestion every year. Aside from the proportion of public transport trips, it is certain that the time and the number of consumers staying in the car are increasing year by year, and the range of consumers affected by the environmental quality in the car is also expanding simultaneously.

  So, what is the latest development of such a long-awaited mandatory standard?

  According to Guangsheng Song, some indicators in the "Guidelines for the Evaluation of Air Quality in Passenger Cars (Draft for Comment)" are stricter, while others are relaxed. In order to improve the number of new energy vehicles, regulations on battery radiation have been added, but the timetable for upgrading to mandatory standards and implementing them is still unknown.

  In this regard, Jiang Suhua believes that both the recommendation standard and the mandatory standard can be used as the basis for the judge’s judgment. This is not to say that the introduction of mandatory standards is not urgent, but compared with the time of introduction, from a lawyer’s point of view, it is more meaningful to modify the content of standards and involve the threshold of data.

  For vehicle manufacturers, the unanimous view of the guests attending the meeting is that improving the air quality inside the vehicle should start from the source, which requires enterprises to respect consumers and reduce pollution sources in product definition, product design, supplier selection, manufacturing, transportation and sales. As Wu Gaohan, former deputy secretary-general of China Consumers Association, said, consumers in China have now entered the stage of developing and enjoying consumption. At this stage, consumers’ pursuit of a better life is unstoppable, and the pursuit of quality consumption is unstoppable. Health is the most important part of a better life. Without health, there is no better life, and without health, there is no quality consumption. (Legal Daily, all-media reporter Cai Yanhong)

He once believed that he was "incapable of making money", and how did he achieve the counterattack?

  They are dolls born and raised in the village, and their parents’ persistent and tenacious blood runs through their veins. They are a new generation of vigorous young people, and their characters are imbued with the background of youth struggle.

  On the road of getting rid of poverty, they dare to fight hard, and together with their parents, they will jointly protect this hot land where they were born. It is because of their persistence and hard work that our countryside is more energetic and hopeful.

  Voice of China launched the specially planned Young People in Our Village — — On the Gua Tian of Hope.

  This is him in the eyes of the villagers:

  Uncle Huang Xulin: "Huang Yousheng in my eyes, he was honest since he was a child, and his family was poor. In order to change his life at home, he went to plant melons in greenhouses, and now life is getting better."

  Brother Huang Shunsheng: "I work hard and eat hard, and I am quite filial to my parents."

  Zhong Pinggen, the branch secretary of Lanpan Village, said: "He is not tall, thin and small. By planting watermelons in recent years, he made some money, and now he is more confident than before. "

  Huang Yousheng: My name is Huang Yousheng, and I am 38 years old. Now I have a 45-mu watermelon field in Fenyi County. It’s hard to grow watermelons, and fertilization can’t be done until the sun goes down. I go fishing by the river and take a nap under the tree when I am free during the day. This is my rare rest time.

  Huang Yousheng shook the soil on his shoes, put the watermelon branches together and put them in the laundry basket, and rolled up the plastic film of the melon shed. The work that started at five o’clock in the morning came to an end at noon.

  There is a small river not far from the watermelon field. Huang Yousheng likes to put his fishing rod in the ground obliquely and take a nap in the shade of the shore. When he wakes up, he can see the fish take the bait. This is his only leisure time in a day.

  In the evening, Huang Yousheng got into the melon shed again. This time, he will be busy until midnight.

  In his spare time, Huang Yousheng likes fishing by the river.

  When I was young, I became the pillar of my family.

  He once said that he was "incapable of making money"

  Lanpan Village, Gaolan Township, Fenyi County, Jiangxi Province, is located in a remote place, and few outsiders visit it all the year round. It was once a poverty-stricken village at the provincial level during the 13th Five-Year Plan period.

  Here, Huang Yousheng, who lives by farming, has a family, and his life is not comfortable. His parents had difficulty walking because of illness, and his brother went out to work and was injured, which made Huang Yousheng become the main labor force at home when he was young.

  Huang Yousheng: I don’t have enough to eat every day, I don’t plant the land well, and I have no money to buy fertilizer. Going out to work is also unskilled, earning two or three thousand yuan a month. I can’t do it even if I want to, so it’s getting worse.

  Huang Yousheng tried many ways to make money. He went to Zhejiang paint factory to do odd jobs and went back to the village to raise chickens, grow watermelons and grow rice. Every time he tried to prove himself, he ended in failure. At that time, Huang Yousheng often said that he was "incapable of making money".

  Huang Yousheng: I want to do something, groping while doing it, but I can’t. First, I don’t have much money; Second, I have no skills. The idea is good, and it is good to dare to do it, but it is bad if you don’t make it.

  Huang Yousheng’s home is in Lanpan Village, Gaolan Township, Fenyi County, Jiangxi Province, which was once a poverty-stricken village at the provincial level during the 13th Five-Year Plan period.

  Pieces of work are intermittent, and all the year round, Huang Yousheng earns only enough money to feed and clothe his family.

  In 2014, Huang Yousheng’s family was included in the first batch of poverty-stricken households in the village. Zhong Pinggen, the branch secretary of Lanpan Village, observed that although Huang Yousheng sometimes lacks tenacity in doing things, he is not lazy. What he needs is someone to enlighten and lead the way.

  Zhong Pinggen: Actually, he can’t grasp the ideological and financial aspects, and he can’t find a good direction. However, he is still honest in speaking and has this kind of honesty in doing things. This is the main thing I see.

  Recommended by the village party secretary to grow watermelons in partnership

  This time he felt "better than working"

  In Fenyi County, watermelon planting is the main poverty alleviation industry, and the county’s watermelon planting area exceeds 62,000 mu. Zhong Pinggen found out that the big growers in the village were looking for someone to grow watermelons in partnership, which was a good opportunity to learn. He recommended Huang Yousheng to help at the first time.

  Zhong Pinggen: The soil here is loess. Watermelon planted in this loess is sweeter than ordinary. Huang Yousheng has two years’ experience in growing watermelons, and it is even more difficult for him to accept it if he is recommended from a newer field.

  Getting the trust from outside the family and being recommended to do things is a shock to Huang Yousheng’s heart.

  Huang Yousheng: I think it’s ok to grow watermelons in partnership, which is better than working. If it is better than working, then I definitely want to stay, earn more money and make my life better.

  In the first year, Huang Yousheng took 20% of the shares in a 120-mu watermelon field and made a net profit of several thousand dollars. This joy didn’t last long. In the third year, Huang Yousheng thoroughly understood that if he wanted to benefit, he had to have scale.

  Zhong Pinggen, the village party secretary, soon heard about Huang Yousheng’s concerns.

  Huang Yousheng: The secretary told me very seriously, did you make any money? I said, I just have no money. The secretary said, don’t give up, the funds can be discussed.

  Zhong Pinggen: At that time, several people in our village committee found him. I said that we could find a way to help solve some of the problems through the policy of poverty alleviation microfinance.

  Get rid of poverty smoothly in 2018!

  The annual sales of watermelons he planted are nearly 120,000 yuan.

  In 2017, poverty alleviation cadres used the financial poverty alleviation policy to win a loan for Huang Yousheng, and at the same time helped him find a piece of land for circulation and expand the planting scale.

  Huang Yousheng breathed a sigh of relief. He got a driver’s license, spent several thousand yuan to buy a second-hand van and stayed in the watermelon field 24 hours a day.

  Huang Yousheng: I want to pick melons at night and load cars during the day. Pick the melons one by one at night, put them there, and then ask the coolie to help me move them out. I’ll sleep in the car at night, and I’ll guard that place. You should watch the watermelon grow.

  During the watermelon planting season, Huang Yousheng often sleeps in this van.

  It is not enough to work hard, and the planting technology should be continuously improved. Learn from agricultural science and technology extension workers how to increase watermelon production and exchange experiences with other growers. As long as it is related to watermelon, Huang Yousheng can be interested.

  Huang Yousheng: The key is to explore the technology. You have to learn while doing it. If there is no "top", the more you learn, the better. Make yourself stronger, so that the products will be competitive in the market.

  In 2018, Huang Yousheng’s life ushered in an inflection point.

  He planted more than 30 acres of watermelons, and the output of two seasons a year made his sales reach nearly 120,000 yuan. Huang Yousheng, who tasted the fruits for the first time, got rid of poverty smoothly that year.

  Now, my brother Huang Shunsheng (left), driven by Huang Yousheng (right), has also started to grow watermelons.

  From foolhardy to expert in growing melons

  Next, he has a "small goal"

  The lush seedlings in the watermelon shed are dotted with yellow watermelon flowers. Huang Yousheng skillfully tidies up the second-season melon seedlings that have just been planted. If all goes well, watermelons will be harvested in late October.

  Huang Yousheng is checking the growth of watermelon seedlings and introducing the experience and skills of growing melons to reporters.

  In the cold and summer, Huang Yousheng’s watermelon planting industry is finally on the right track.

  Through continuous learning and exploration, he has changed from a previous foolhardy to an expert in growing melons, and has also mastered a little knowledge of management and sales. Now, Huang Yousheng is more willing to take the initiative to talk to Zhong Pinggen about the plan of planting melons and his own experience.

  Zhong Pinggen: He is getting more and more diligent, and he has also driven the surrounding villagers to earn some money. Our villagers go to work in his melon land, which costs about 70-80 yuan a day, and they need 7-8 people every day, and sometimes more than 10 people, which will nearly reach 80,000 yuan to pay for labor.

  Huang Yousheng hired local villagers to take care of the watermelon field together.

  Today, Huang Yousheng is inseparable from the help of the villagers. Similarly, Huang Yousheng is not only willing to share his rich experience and planting techniques with other poor households and drive everyone to grow melons together. He also hopes that the more people, the better.

  Huang Yousheng: I just want to find a few more poor households, bring them together, and let’s make a joint venture and plant 300 acres of watermelons to make some money. That’s what I think in the next few years.

  At the end of last year, with the help of village cadres, Huang Yousheng applied for a loan of 50 thousand yuan through the financial microfinance poverty alleviation policy. All of this money, Huang Yousheng, was invested in the expanded production and operation of watermelon.

  Now, his watermelon planting area has reached 45 mu. In the days that accompanied watermelon day and night, Huang Yousheng realized some truth.

  Huang Yousheng: My impatience will wear off. I am not as impatient as before. Just like planting a watermelon, it will grow slowly, so you have to wait patiently for it. It can’t be rushed by you. It’s useless to rush.

  Huang Yousheng introduced that there are five melon sheds in an acre of watermelon field, and when the year is good, the yield per acre is about six or seven hundred kilograms.

  Like a seed buried deep in the ground, Huang Yousheng survived the difficult winter. He is full of longing for the future.

  Huang Yousheng: I didn’t have a direction at first, but now I have a direction, and my mood is much better. I will work hard towards this goal and have a good start. Now I have two children, the older one is Zhiwen, and the younger one is Zhichao. I hope they will study hard and come back with some knowledge. If they want to grow watermelons, they may grow them better than me.

  For the future, Huang Yousheng is full of longing.

  To myself after 20 years.

  Huang yousheng

  Huang Yousheng, I was you 20 years ago.

  Now that I am a grandfather, Zhiwen and Zhichao should be very filial.

  Although you are in your sixties, I know you will be busy.

  Has my wish to set myself 300 mu of unicorn melon come true this year?

  I hope everything is all right in my house!

Fertility assessment helps women better understand their fertility potential.

Authors: Deputy Chief Physician Zhu Xiaodan, Department of Obstetrics and Gynecology, Putuo Hospital, Shanghai University of Traditional Chinese Medicine.

At present, the global fertility problems are increasing day by day, and the overall fertility of women is on the decline. Women are facing various pressures in modern society, including occupational pressure, family pressure, social expectations, and the unhealthy lifestyle that follows, which makes the fertility of contemporary women decline more and more "younger". At present, the incidence of infertility is as high as 10%~18%. In 2023, the birth rate in China was as low as 6.4‰.

National birth rate

In the reproductive endocrinology clinic, patients often ask: How is my fertility? Can you still be born? Faced with such a question, today, let’s talk about this topic.

As we all know, to complete a successful pregnancy, women need the cooperation of the whole reproductive system and all organs of the whole body. Therefore, the evaluation of female fertility is divided into three parts: the first part is the evaluation of ovarian reserve function, the second part is the evaluation of the structure and function of uterus and fallopian tube, and the third part is the evaluation of general state.

First, the ovarian reserve function

The ovarian reserve function of women refers to the quantity and quality of eggs, that is, the "inventory" of follicles with growth and development functions. The number of follicles in women has been determined at birth and is non-renewable. With the increase of age and the progress of menstrual cycle, the number of eggs gradually decreases. So how do we evaluate how much "inventory" there is in the ovaries?

1. Age

Age is the primary factor to evaluate fertility, and the best reproductive age for women is 23~32 years old. With the increase of age, fertility gradually decreases, pregnancy rate and live birth rate decrease, and abortion rate increases. With the increase of age, ovarian function declines irreversibly, and the number of follicles and the quality of eggs decrease. Age-related abnormal vascularization, oxidative stress and free radical imbalance in the ovary will lead to the decline of oocyte quality, which will lead to fertilization failure or abnormal embryo development.

The picture comes from the Internet.

2. Basic follicle stimulating hormone (bFSH)

BFSH is the level of serum FSH on the second to fourth day of menstruation, and it is one of the indexes to evaluate ovarian reserve function. The main reasons for the increase of bFSH level are the aging, the decline of ovarian function, the decrease of E2 secretion, the weakening of negative feedback on hypothalamus-pituitary-ovarian axis, and the subsequent increase of FSH. When the serum level of bFSH is higher than 10u/L, the ovarian reserve function is decreased, and when the serum level of bFSH is higher than 18u/L, the live birth rate is almost zero.

3. Basic estradiol (bE2)

BE2 refers to the level of serum E2 on the 2nd to 4th day of menstrual cycle, which can be used as an index to evaluate ovarian reserve function. When the bE2 value is more than 74.9 pg/ml (274.134 pmol/L), the ovarian function is decreased or the pregnancy outcome is poor when in vitro fertilization (IVF) is performed, and the number of embryos obtained is small.

4. FSH/LH (follicle stimulating hormone/luteinizing hormone) ratio

FSH/LH ratio can be used as an index to reflect ovarian function, and can also be used as a sign of ovarian response to gonadotropin to predict pregnancy outcome. When FSH/LH > 2, it is suggested that the ovary may have a bad reaction to gonadotropin in assisted reproductive technology. When FSH/LH > 3.6, the ovarian function is obviously decreased, and the cancellation rate of IVF ovulation cycle is high.

5. Anti-Miller hormone (AMH)

AMH is mainly produced by primary follicles, preantral follicles, sinus follicles, etc. It regulates the growth and development of follicles and is not regulated by hypothalamus-pituitary-ovary axis. As a reliable index of ovarian reserve function, it can be detected on any day of menstrual cycle. Serum AMH concentration was negatively correlated with age. AMH value reaches its peak in adulthood (about 25 years old), generally drops significantly after 36 years old, and approaches zero when approaching menopause.

6. Inhibin B(INH-B)

INH-B appears from the pre-antral follicular phase and is regulated by FSH. INH-B level, as a direct index to predict ovarian reserve function, reflects ovarian reserve. On the third day of menstruation, the blood INH-B < 45 ng/L indicates that ovarian function is decreased.

7. Sinus follicle count (AFC) and ovarian volume

AFC, ovarian volume and ovarian interstitial blood flow parameters can be used as evaluation indexes of ovarian reserve function and responsiveness. AFC is significantly correlated with age and basic hormones. With age, the number of follicles decreases exponentially. Ovarian volume can reflect the number of follicles and the situation of ovarian reserve pool from another angle. With the increase of age, ovarian function declines and ovarian volume shrinks. The most commonly used parameters of ovarian stromal blood flow are the peak velocity of ovarian stromal blood flow (PSV) and resistance index (RI). High PSV and/or low RI indicate that the ovarian interstitial blood supply is abundant and the ovary responds well to gonadotropin.

Second, the evaluation of the structure and function of reproductive tract

Because of the special anatomical structure and physiological function of female reproductive tract, the evaluation of reproductive tract structure and function is also an important link in fertility evaluation, including vagina, cervix, uterus, fallopian tube and pelvic cavity.

1. Detection of vaginal microecology

Female reproductive tract flora is closely related to every step of ovulation, sperm transport, fertilized egg implantation, pregnancy and delivery. Reproductive tract infection of women of childbearing age affects their reproductive health, damages their reproductive function and increases the risk of infertility.

2. Detection of cervical lesions

Cervical diseases tend to be younger, which are closely related to fertility and pregnancy outcome. Regular gynecological physical examination, cervical liquid-based thin-layer cytology (TCT) and human papillomavirus (HPV) screening should be conducted to detect cervical diseases as soon as possible.

3. Detection of uterine abnormalities

Non-invasive ultrasound, such as hysteromyoma and endometrial polyp, is the most widely used examination method to evaluate the receptivity of uterus and endometrium, and to evaluate the shape, thickness, volume, peristalsis wave, uterine artery and hemodynamic parameters of endometrium. Hysteroscopy is the gold standard for the diagnosis of endometrial lesions, which can accurately identify cervical lesions, intrauterine lesions, abnormal endometrial morphology and abnormal tubal opening through endoscopy. Endometrial biopsy can also be performed. At present, there are cytokines, various receptors, endometrial receptivity chips and other detection methods to evaluate endometrial receptivity, and the research on endometrial receptivity is constantly expanding.

4. Tubal patency test

Including salpingostomy, hysterosalpingography/contrast-enhanced ultrasound and laparoscopic salpingostomy. At present, hysterosalpingography has become a research hotspot with its unique advantages (real-time dynamic, visualization and no radiation), and has gradually become the first choice for tubal patency examination. Liquid drainage has some shortcomings, such as invisibility, blindness and great difference. X-ray radiography, as a traditional method of tubal patency examination, mainly has the disadvantages of adverse reaction of contrast agent and radiation damage. Laparoscopic salpingostomy is the "gold standard", but it is not the first choice for the time being because of invasion, hospitalization, high cost, surgery and anesthesia.

The picture comes from the Internet.

5. Detection of pelvic factors

Pelvic diseases are closely related to female fertility, such as pelvic endometriosis, pelvic tuberculosis, pelvic adhesion, tubal diseases, hysteromyoma, ovarian tumors and pelvic inflammatory diseases. Laparoscopic surgery can find and diagnose abnormal pelvic conditions in time. For infertility caused by fallopian tube factors or uterine cavity factors, hysteroscopy combined with laparoscopy can treat pelvic cavity, fallopian tube and uterine cavity diseases accordingly, which has important clinical value for female fertility evaluation, diagnosis and treatment.

6. Female reproductive tract dysplasia

Abnormal development of female reproductive tract includes abnormal development of vagina, cervix, uterine body and fallopian tube, with or without abnormalities of ovary and urinary system. The combination of pelvic ultrasound and MRI examination is the best examination method for reproductive tract dysplasia.

Third, the general state assessment

In terms of systemic diseases, we should evaluate whether there are diseases that affect fertility or are not suitable for fertility, such as thyroid diseases, familial genetic diseases, blood system diseases, cardiopulmonary diseases and tumors.

1. Thyroid diseases

Abnormal thyroid function can lead to infertility and poor pregnancy outcome, so it is suggested that women with family planning should monitor thyroid function. Clinical hyperthyroidism can lead to abortion, premature delivery and thyroid crisis, and timely treatment can significantly reduce these risks; Infertile women with subclinical hypothyroidism should be treated with levothyroxine (LT4).

2. Hereditary diseases

According to the etiology, it can be divided into monogenic diseases, polygenic diseases, chromosomal diseases, mitochondrial genetic diseases and somatic genetic diseases, which have the characteristics of congenital, lifelong and familial. It is suggested that couples with rare diseases or couples who have given birth to rare diseases should have genetic testing and genetic counseling, reproductive risk assessment and guide reproductive decisions. The genetic diagnosis (PGD) before embryo implantation was provided after the pathogenic gene locus and genetic mode of the family were clarified.

3. Other general conditions

Nutritional status is a very important factor in regulating reproductive process, which is closely related to female reproductive function. For example, obesity and malnutrition have adverse effects on internal environment, egg quality and embryo development. In addition, mental state, living environment and systemic factors also need comprehensive consideration. Whether a woman’s whole system can withstand pregnancy is also the concern of fertility evaluation, including whether she is complicated with diabetes, hypertension, heart disease and tumor.

4. Who needs fertility assessment?

1. Couples who have been pregnant for more than 1 year without pregnancy;

2. People who have had many bad pregnancies in the past;

3. People who have had multiple abortions or ectopic pregnancy in the past;

4. Women of childbearing age with less menstrual flow, irregular menstrual cycle and dysmenorrhea;

5. Obese or thin people (BMI>24 or BMI<18.5);

6. White-collar workers who stay up late and work overtime for a long time;

7. People who use computers and mobile phones for a long time to work in a radiation environment;

8. People with smoking, drinking, drug addiction and other habits.

In a word, fertility assessment can help women understand their fertility potential and possible fertility problems. In fact, whether you have the desire to have children at present or not, regular fertility assessment can help you plan your birth plan reasonably, receive corresponding medical help in time, and don’t leave regrets for your life!

  Is "artificial meat" edible? Is online celebrity food reliable? Are probiotics really useful? What foods have you paid attention to in the past 2019? What troubles have they brought you? Food safety concerns people’s health and life safety. At the "Media Communication Meeting on Scientific Interpretation of Food Safety and Health Hotspots in 2019", which was directed by China Association for Science and Technology and hosted by chinese institute of food science and technology recently, experts combed and interpreted the hot events of food safety that the public paid attention to in the past year, and made suggestions for food safety supervision by popularizing food safety knowledge through examples. This edition extracts some hot topics to interpret.

"artificial meat"

Scientific and technological problems to be solved, standards and regulations to be improved.

  Interpretation expert: Wang Shouwei (Director of China Meat Food Comprehensive Research Center and Dean of Beijing Food Science Research Institute)

  "Artificial meat" is synonymous with foods that are not naturally produced and have a similar taste to meat. It is usually divided into two categories: vegetable protein meat and cell cultured meat. The emergence of "artificial meat" on the one hand is to meet the rapidly growing meat demand of consumers, on the other hand, it provides a way to effectively reduce the land occupation of animal husbandry, the use of water resources and greenhouse gas emissions, and solve the problems of environmental protection and sustainable development.

  In recent years, the processing technology of vegetable protein meat is becoming more and more mature at home and abroad, and many enterprises have developed vegetable protein meat products with vegetable protein as raw materials. The research on using animal stem cells to produce cells to cultivate meat has also made great progress, and many enterprises have announced that they can develop cells to cultivate meat in the laboratory. Vegetable protein meat has great market potential and a high degree of commercialization. In the future, developing products more similar to real meat has become a direction for the food industry and scientific and technological circles.

  In the innovation and development of "artificial meat", it is necessary to increase scientific and technological input and solve the existing scientific and technological problems of "artificial meat". For example, research on the formation mechanism, raw material supply and processing technology of vegetable protein meat should be carried out to build a new research and development system. In the process of industrialization, we pay attention to improving the flavor, texture and nutrition of products, and constantly meet the increasingly diversified needs of consumers. Carry out research on the basic theory and key production technology of cell-cultured meat, and establish a production technology system of cell-cultured meat suitable for human food manufacturing.

  While innovating and developing, adhering to product quality and safety is the foundation of the development of "artificial meat". It is suggested that the new ingredients and new production technology added in the production of "artificial meat" should be systematically evaluated for safety, and an independent standard system and an objective supervision system should be formed in the evaluation of product safety and nutritional components, so as to promote the benign development of the industry.

  Scientific and rigorous standards are the cornerstone of the healthy development of the industry. In China, the development momentum of vegetable protein meat industry has been formed, and the product categories are relatively mature, but the existing laws and regulations are not suitable for product innovation and industry development; The development of its standard should be carried out as soon as possible, and the definition, classification method and production technology should be clearly defined, which will provide convenience for government supervision and provide reference for the direction of production and innovation of products in the industry. In addition, the research and development of cell-cultured meat in China is still in its infancy, but the development speed is very fast, and the research on standards and supervision methods has just begun; The division of supervisory responsibilities and division of labor system should be clarified, and a strict system of standards and laws should be formed. In addition, public science popularization should be carried out to guide consumers to correctly understand and rationally consume "artificial meat".

Online celebrity food

Strictly guard against the transformation of "red and black"

  Interpretation expert: Ma Guansheng (Head of the Department of Nutrition and Food Hygiene, Peking University College of Public Health)

  Some sellers make use of social media’s special publicity and marketing methods to dress up homemade food as "online celebrity" food, which is popular in the circle of friends. From home-made delicious food to home-brewed fruit wine, from morning tea snacks to midnight snacks, from beauty soup to dietary remedies, there are all kinds of foods in the circle. Online food attracts waves of consumers with its novel appearance, photos or taste. However, when consumers buy food, they often ignore the quality of the food itself, including raw materials, production date, shelf life and production address.

  Due to the special sales channels (such as WeChat circle of friends, micro-stores), online celebrity food has some problems, such as difficult management and lack of effective supervision mechanism. Taking the incident of "there is no milk in milk tea" in online celebrity as an example, China’s national standard "Tea Beverage" (GB/T 21733-2008) defines milk tea drinks and milk tea-flavored drinks as liquid drinks prepared by taking water extract of tea or its concentrated solution and tea powder as raw materials and adding one or more of milk or dairy products, sugar and/or sweeteners, edible milk flavor essence, etc. Although there is a requirement for the protein content of milk tea in this standard (&ge; 0.5%), but milk or dairy products are still only one of a variety of optional ingredients, not a hard requirement. Therefore, due to the lack of clear standards for existing milk tea, there is an embarrassing situation that "milk tea does not contain milk", which increases the maneuverability of merchants and brings blind spots to food safety supervision.

  It is suggested to improve the supervision mechanism and clarify the responsibilities and supervision methods of all parties in the business activities of non-traditional foods such as online food sales. At the same time, strengthen regular sampling and random inspection, and urge network platforms and production operators to implement the main responsibility. Strike hard at illegal food safety behaviors in online sales, strictly investigate and deal with behaviors such as "brushing the bill" and "false comments", and protect consumers’ rights and safety with strict supervision.

  Online celebrity food is mainly sold through the online platform, so the online platform should assume the responsibility of screening and supervision. The network platform should establish a mechanism to help the superior and limit the inferior, strictly control the entry threshold of merchants, inspect and regularly review their retail qualifications and relevant licenses for selling products, and prevent counterfeit and shoddy foods from being sold on the network platform. Food enterprises and individual food producers should strengthen the construction of industrial chain safety, ensure the safety and traceability of product sources, make the product chain clear, and prevent and control risks. As consumers themselves, they should constantly improve their health literacy and food safety literacy, make rational purchases, and not blindly "chase after the red".

probiotics

The efficacy has the specificity of strains and people.

  Interpretation expert: Chen Wei (Academician of China Academy of Engineering, Chairman of Probiotics Branch of chinese institute of food science and technology, Vice President of Jiangnan University); He Guoqing (Vice Chairman of chinese institute of food science and technology Probiotics Branch, Professor of Zhejiang University)

  Probiotics have a strict definition: they must be living microorganisms, which are beneficial to the health of the host when ingested in sufficient quantities. Moreover, the health function of probiotics should be based on scientific and rigorous clinical trial evaluation and evidence-based medical evidence. At present, tens of thousands of published academic papers have studied the functions of different probiotic strains, confirming that the core function of probiotics is to improve the health of human gastrointestinal tract. In addition, in vitro experiments such as cell model, animal experiments and human experiments show that probiotics may have potential beneficial functions to improve metabolism and nervous system. However, in vitro experiments and the actual human digestive system are completely different worlds, and the results of in vitro experiments can never be used to claim the functions of probiotics. Animal experiments can be used as a reference, but it needs to be confirmed by large-scale and deeper human or clinical experiments.

  It is a long-term, rigorous and scientific process for human beings to explore the efficacy of probiotics. At present, there are various probiotic products with claimed functions on the market. However, it should be emphasized that the academic community has reached a consensus that the core function of probiotics is to improve gastrointestinal health.

  Generally speaking, the mainstream probiotic strains in the market are all isolated from healthy people and fermented foods with a long history of safe use. Most of them are considered as non-pathogenic symbiotic microorganisms, and their safety has been recognized by authoritative organizations. Of course, for sick individuals, such as patients with severe infection or immunodeficiency, they should be used with caution or consult a doctor.

  It should also be noted that the efficacy of probiotics has the specificity of strains and people. There are differences in probiotic efficacy among different strains; There are also differences in physiological regulation of probiotics among different hosts. Therefore, in the future, we should confirm the relevant probiotic functions at the strain level, judge and apply the individual functions of probiotics according to the individual characteristics of different hosts, and pay attention to personalized precise nutrition. Of course, the industrial application of probiotics must also be verified by scientific and rigorous processes. For example, the species, even the genetic composition and basic physiological and biochemical characteristics of the strain are first studied, and then the adaptability, safety and probiotic characteristics of the strain are evaluated in turn, and finally the probiotic dosage and probiotic combination with satisfactory efficacy are selected.

  In addition, consumers should choose probiotic-related products scientifically and reasonably. For lactic acid bacteria drinks, consumers should pay attention to distinguish product types when purchasing. According to the relevant standards in China, the labels of lactic acid bacteria drinks should be marked with live bacteria (non-sterilization) or non-live bacteria (sterilization), and they can be distinguished by labels when purchasing. When consumers buy yogurt, they should keep it reasonably according to the label. Low-temperature yogurt should be sold in cold storage. When they return home after purchase, they should put it in the refrigerator as soon as possible and drink it in time to ensure its strain activity.

  Probiotics have individual differences in their effects on health, and there is no "all-purpose" probiotic strain, which is suitable for everyone and all physical conditions. We should further strengthen the popular science education of consumers, popularize the professional knowledge of probiotics and clarify the scientific concept of "quantity" of probiotics, so that consumers can rationally choose probiotic products.

Self-heating food

It is necessary to cross the safety hurdle of "self-heating package"

  Interpretation expert: Lu Fuping (Vice President of chinese institute of food science and technology and Vice President of Tianjin University of Science and Technology)

  Self-heating food is a product that heats food with flameless self-heater and quickly reheates it to edible state. In recent years, a series of self-heating products represented by self-heating hot pot have developed rapidly. Besides the common self-heating hot pot and self-heating rice, there are also self-heating porridge, noodles, rice noodles, soup, etc., which are diverse and meet the urgent needs of consumers for hot food in more consumption scenarios.

  Although the safety of self-heating food is generally controllable, the safety risk of "self-heating package" should be paid full attention to. Since self-heating food uses the chemical reaction between heating agent and water to generate heat to heat the food. Occasional phenomena such as "self-heated food rupture" or "unstable temperature of self-heated food" have aroused people’s concern about the safety of self-heated food.

  Under the current self-heating technology in China, the chemical self-heating package used for self-heating food is mostly magnesium/iron for military use and aluminum-water for civilian use. No matter what kind of heating package, a small amount of hydrogen will be produced when heating. If individuals eat or a small number of people gather to eat, even in a closed environment, the amount of hydrogen generated by the heating of the heating package is far from the limit that can cause explosion. Under normal circumstances, the normal products will be eaten according to the normal operating procedures, and there will be no risk and safety problems such as cracking. However, if people eat a lot of self-heating food at the same time in a closed environment, or if the vent hole on the self-heating food packaging box is blocked, there may be potential safety hazards, which need to be paid full attention to.

  It is suggested to increase the research on the safety of self-heating package and develop a self-heating package with high efficiency and good safety. By developing energy-efficient formula and new heating device, the generation of hydrogen and water vapor can be controlled or reduced, the demand for energy efficiency release and utilization can be improved, and the safety level can be improved. Develop a new type of physical self-heating device, use renewable energy and reduce pollution. In addition, it is necessary to enhance the effectiveness and support ability of the self-heating device in various scenarios.

  The rapid development of self-heating food industry has attracted a large number of enterprises to join. However, due to the imperfect standards and specifications of self-heating food, the enterprises that have joined the self-heating food industry are mixed, which seriously affects the healthy development of the industry. At present, only the group standard "Self-heating Convenient Cuisine Products" issued by China Business Federation in 2017. From the perspective of regulating the industry, self-heating food needs more stringent standards to ensure its healthy development. It is understood that the industry is actively exploring how to establish a unified standard, for example, by standardizing the chemical composition and proportion, heating intensity, hydrogen production and other indicators contained in self-heating food heating packages, and making clear requirements for the treatment of final waste, so as to improve the entry threshold of the industry and standardize the healthy development of the industry.

Special medical food

Not for everyone

  Interpretation expert: Ren Fazheng (Academician of China Academy of Engineering, Vice Chairman of chinese institute of food science and technology Probiotics Branch, Professor of China Agricultural University)

  Special medical food is formula food for special medical use, which is specially processed and prepared to meet the special needs of people with limited eating, digestive and absorption disorders, metabolic disorders or specific disease States for nutrients or meals. It also has a very strict classification, which is currently divided into two categories: people aged from 0 months to 12 months and people over 1 year old.

  On the basic functions of special medical food &mdash; &mdash; At present, there is a broad consensus on nutritional support, including improving the treatment and rehabilitation effect, shortening the course of disease, reducing medical expenses, increasing the turnover rate of hospital beds, and reducing the readmission rate, which can be solved through nutritional support and special medical food. The World Health Organization has proposed that if more money is invested in nutrition and health care, less 8.5 yuan can be spent on treatment and the cost of rescue in 100 yuan can be saved. It can be said that the nutritional support function of special medical food is indispensable in clinic. Of course, it can’t replace drugs.

  Special medical food is a new industry in our country, and our government attaches great importance to it, and has made very strict management regulations at the beginning of the industry development. Special medical food should be registered by the food safety supervision and administration department of the State Council, and the formula of special medical food should be based on the research results of medicine and nutrition, and its safety and clinical application effect need to be scientifically confirmed.

  According to news reports, some illegal enterprises produce ordinary solid drinks, pass off as special medical milk powder and mislead consumers. This kind of behavior belongs to false propaganda, which should be severely cracked down and strengthened management. In addition, when the special medical food is registered and put on record, the product formula and production technology are strictly regulated. Food enterprises should produce special medical food according to the registered formula, and cannot produce special medical food without obtaining the registered formula and production license.

  The demand emphasizes that special medical food is special and not suitable for everyone. Moreover, different special people need different special medical foods. We should strengthen the popularization of special medical food, let consumers know its particularity and eat it according to the doctor’s advice.

Reduce salt, oil and sugar

Science and technology lead, scientific implementation

  Interpretation expert: Chen Junshi (Academician of China Academy of Engineering, General Consultant of National Food Safety Risk Assessment Center)

  The diet of Chinese residents is high in salt, oil and sugar. "Three reductions" is not an isolated matter, it is an important part of the whole reasonable diet. Whether it is the government supervision department, food industry or consumers, it is necessary to raise awareness and establish the concept of "reasonable diet".

  Carrying out the "three reductions" action is not a matter for any department or enterprise, but should be coordinated and promoted by all parties. The government should formulate corresponding policies to lead the "three reductions" action, and catering and food processing enterprises should provide diversified products with different levels of salt, oil and sugar for consumers to choose by reducing the use of salt, oil and sugar. Residents gradually reduce the use of salt, oil and sugar in their daily cooking.

  In particular, the food industry and catering industry should accelerate the transformation and upgrading of nutrition according to the health needs of consumers, and take the initiative to take measures to reduce the use of salt, oil and sugar in food. This requires increasing scientific and technological support, laying a solid scientific foundation, solving the problems such as product flavor change and shortened shelf life that may be caused by "three reductions", innovating and developing new foods, and leading a healthy transformation with science and technology. In addition, there are different dietary nutrition problems in different regions and different groups of people, so nutrition science education should be targeted and reflect differentiation. Nutrition intervention should be precise, and the implementation of policies should be based on science and practical. Focus on guiding enterprises to provide more differentiated products for consumers to choose, and guide consumers to choose products that suit them reasonably.

  The action of "three reductions" needs to be carried out step by step in line with China’s national conditions, instead of "eating a fat man at one breath". It takes time to change people’s tastes, not quick. The improvement of cooking, methods and food processing technology also takes time, which cannot be achieved overnight, and should be carried out step by step in accordance with scientific laws. The transformation of consumer health concept needs long-term positive guidance and popularization of scientific knowledge. Therefore, the implementation of the "three reductions" action must be gradual, and various problems must be solved step by step.

Food fraud

Counterfeiting detection technology needs to be upgraded

  Interpretation expert: Wu Yongning (Chairman of chinese institute of food science and technology Food Authenticity and Traceability Branch, Technical Chief of National Food Safety Risk Assessment Center); Chen Ying (Vice President and Chief Engineer of China Academy of Inspection and Quarantine)

  Food quality, food safety and food truth are three attributes of food. The authenticity problems such as food fraud and forgery exist at home and abroad. For example, as the saying goes in China, "selling dog meat by hanging sheep’s head" and the "horse meat passing off as beef" that happened in Europe a few years ago. The World Health Organization once pointed out that apart from food-borne diseases, more and more food fraud and food fraud problems need to be paid attention to.

  Ensuring the authenticity of food is not only to protect public health, but also a necessary measure to curb the market chaos of "bad money drives out good money", standardize the market competition order and boost food consumption confidence. At present, China has basically met the public’s requirements for the quantity and quality of food, and the concern for food safety has reached a higher level. However, for a long time, the investment in food authenticity technology is relatively lacking, and it is difficult to guarantee the scientific supervision of "food authenticity". If food fraud is "a magic height of one foot", then the detection technology of counterfeit identification must be "a magic height of one foot".

  It is suggested to increase the scientific and technological investment in food authenticity research and overcome the technical difficulties and supervision problems of food authenticity. At the same time, speed up the transformation of technical standards of food authenticity, formulate corresponding detection methods and standards, and provide technical support for scientific supervision of food authenticity in China.
