Medical security and medicines, food security are questions concerned by society most. See the food of all medias, safe incident of medicines again and again in recent years, initiate the expert's thinking: How do medical science, common Wei experts play a more important role among them? How to pass the scientific sound of media communication? Chinese Medical Association popular science branch held a few days ago " Public health and safety and media's community responsibility " The seminar, it is launched exchanging with nutritionist, chief epidemiology expert,etc. that China's chief food hygiene is safe. Analyse and explain the intersection of public health and the intersection of case and very difficult the intersection of China and disease accuse of central the intersection of epidemiology and chief smooth expert I hoped that can be let you understand through my introduction, the scientists will pay great efforts more, could analyse and explain a public health case. First ammonia butterfly purine incident is investigated for June of 2007 of a wave of seventy percent discount, Guangxi, Shanghai, Beijing, Hebei,etc. large leukemia patient of hospital because of the injection in the sheath ' To injection in the spinal) Purine of first ammonia butterfly which Shanghai Hua Lian pharmaceutical factory produced, some patients had low limbs paralysis suddenly, back the intersection of backbone and the intersection of nerve and root that cause change the sex very much difficult to recover. Such a question appears in hospital of more than 20 of the first, second and third, it is an extremely serious incident. Relatives ask the responsibility, the medical worker is hit because of being unable to answer, one director is besieged. Ministry of Public Health, national food medicines have supervised the administration bureau stopping the products with suspicious problem first quickly, then launch various investigations. Check the result is normal, are checked with the standard of European Union's standard, Unite States Standard, pharmacy enterprise separately with the national standard of our country. In a word, the inspection standards that can expect have been all tested, the result accords with the regulation. Ministry of Public Health requires me to lead the investigation group to carry on the investigation at this moment, attempt to open the dense fog. I command carrying on on-the-spot epidemiology to investigate, are distributed at the intersect according to flow direction and patient of medicines, locked and paralysed and related to first ammonia butterfly's purine products in the special lot number of the sheath note from epidemiology, but carry on the laboratory to the products repeatedly and measure or can't find the clue. To apparatus resistance wire burn out and refrigerant sneak into might influence go on investigation later, still gainless. The preliminary investigation conclusions of the related departments are: Because without evidence, have not investigated the responsibility of pharmaceutical factory and hospital. We believe very much epidemiology can adjust and make the thing clear, this can't end up in nothing definite. Then, I have taken the lead in writing three letters to Ministry of Public Health, demanding to continue investigating further strongly, the scientist does not promise that give up halfway. We reflect some hospital use, use afterbirth glucoside, candy of A, only, the similar problem has appeared too by first the intersection of ammonia and the intersection of butterfly and purine. Do I consider whether there is possibility that the third kind of material has infected candy afterbirth glucoside of purine of first ammonia butterfly and A at the same time? We still demand to stop all medicines of these two kinds of lot number that this factory produces. This is paid attention to by the State Council, I am asked to enter Zhongnanhai and talked with group leader of the expert of Bureau of Drugs Supervision. On this basis, two experts make two up in order to go to Shanghai to investigate constantly. According to the hypothesis that I put forward, found at last it was new alkali in Changchun that polluted these two kinds of medicines at the same time. The reason is that the factory mixes 3 kinds of medicines on a production line and produces, someone operates violably, have caused pollution. Because of polluting the trace very much, though the apparatus measured is that world is most advanced, but if there is not goal laboratory, or can not find out. Like looking for a strange beast in the sea, if does not tell you the accurate area, can't find in any case. Suspect and get to new alkali in Changchun like having accurate areas to make a reservation, find out once turning over the stone. It is very difficult to ask for the reasonable determined complicated incident of investigation and collect evidence live for the people, because of concerning the interests of the producer, someone will conceal, mislead. Probably the producer know the fact, but will fear huge compensation without saying. The administrative department that perhaps has is afraid of bearing responsibility, say that cooperates with you, but is afraid oneself is responsible for managing, take a passive attitude. While involving local protectionism, department's interests, administrative resistance is often greater than the difficulty of scientific research. The scientist must ask for reasonable resolution and consciousness for the people, insist on the scientific style, seek truth from facts, a big problem is a big problem, a small problem is a small problem. This investigation in 2007, if without the support of the State Council and Ministry of Public Health, perhaps because resistance can not go on greatly. So, need strong support and need the scientist's will. " medical detective " Need well-trained team to investigate various persons of complicated public health event, known as " Medical detective " ,This needs multi-disciplinary group, need well-trained team. The young and middle-aged expert's team can not catch up with now, because he does not have so many to practise, there is not so many to realize, must pass " dry middle school " Specially train. Ministry of Public Health specially offered the on-the-spot epidemic disease training project in 2001. A large number of practices prove, been solved a large number of difficult problems by the person training, but there is not person trained that have inadequate experience, not all right even if the doctor graduates. Better scientist, the incident has not been exposed to certain extent, can not solve a case temporarily too. The public health needs participating in together, should train a kind of moral integrity - -Health quality, this demands to know health knowledge, hold the healthy behaviour, care the public is healthy. No matter what an authoritative media reporter you are, you should carry on the localization for one's own knowledge, in this that you report, how much do you really know? What size is there the right to speak? I think this is an ethical quality question too, the purpose is to maintain the healthy public opinion environment, promote the society to be harmonious. I want finally to say, the public health is the whole society, by you, by me, depend on everybody. Academician of risk analysis Chinese Academy of Engineering the intersection of you and stone risk analysis frame Chen in the food security need each side to follow Any country and government should solve the food security problem in the world, all must follow the intersection of risk and analysis frame, key see who do well. The frame is divided into three parts, Part one It is the risk assessment. This is a pure expert's behavior, not influenced by any political/economical, culture, life and eating habit, it is all accurate to assess the the four seas where the result is put. Such as the duck's egg incident of the heart, it is that the industrial chemicals are not food additive that the expert's task finds out the Sudan red, it is a poisonous harmful substance. Further study to know, should eat 1000 and eat for a long time per person per day, may cause danger to the health, and the prerequisite is to assume people are as sensitive as animal. After risk assessment, give the result to the government, the risk administrator makes decision according to the result that the expert assesses. Will consider factors such as the local political/economical, culture at that time,etc. soon when doing decision. So the conclusion of risk assessment is common to the whole world, but measures that every country takes may be different. As to this incident, the government should take two control measures: First, stop producing red strictly The intersection of heart and duck's egg, list already lower shelf retrieve at once. Second, should tell consumers as soon as possible, the government has already taken the requisite measure, please rest assured; If has already eaten the heart duck's egg, needn't worry either, because it will not cause danger to the health to assess according to science. What about the current situation of food security of our country food security should pay close attention to most, the member of the standing committee of the National People's Congress proposes while discussing " food safety law " this time, the overall food security environment of our country is good, a great deal of problems that but exist, some problems are still very serious. But in consumers' impression: "What can we still eat? " I think consumer and scientist, government to " What is a food security question paid close attention to most " View the same. The scientist thinks, it is the main food security question that the ones that pollute the food and lead to the fact eat source disease, because there are original funguses of pathogenic venereal disease. But the security question that consumers pay close attention to most is food additive. This conclusion is the investigation carried on according to information center of a Asian food of Bangkok, most Asians answer: Food additive is the food security question that oneself pays close attention to most. And it is essential, safe to accord with standard food additive in fact. These scientific knowledge should be transmitted to common people through the media by the expert. Setting up food appraisal agency as soon as possible, the media reports to the food security incident the frequency is very high during these days. After gathering the cyanogen amine incident three times, we thought we could let out a sigh of reliefed, the question of the milk rose outside one by one finally. Our present information is absolutely asymmetric. In fact we eat very well, children's development is getting better day by day. The data just released reveal, woman's average life span of our country is close to the level of developed country, prove our health status is on the whole better and better. The food security question concerns health, but not a pure public health question, still influence the reputation of the country. Cite the example that a Chinese dairy products mostly detect benzoic acid. Actually this was a scientific paper, it was a Guangzhou scientist's article published on foreign countries. The article very clearly writes, benzoic acid is very low the quantity of detection in the dairy products, will not cause danger to consumers safely. The media lost shape while reporting, reported the dairy products mostly detected benzoic acid finally, and will lead to soon " Infant and pre-school children's health merits attention " ,Then statements such as above standard 3600 times,etc. appear. The specific report is even led to " Intend to add " Have. In fact the milk is not aseptic, expelling will include the fungus. The bacterium will turn benzoylaminoacetic acid that will contain of the milk into benzoic acid. So long as according to the operational procedure, store at the low temperature, transport to the factory fast and process, there is very little benzoic acid amount contained by it, it is one of the normal compositions of the milk. A little such benzoic acid will not cause danger to consumers. Reduce the question of the information asymmetry of the food security, need exchanging, guide consumers correctly. American peanut butter salmonella incident, involve more than 40 states, cause 600 people to infect. American media report, state fact just, have how much state happen incident, have how much product retract, how many cases there are, in panic that consumers of U.S.A. do not have, dare to eat the peanut butter. The scientist has responsibility to evaluate products, the assessment result needs to notify. Hope after the food safety law is issued, our country sets up such an organization as soon as possible. I propose, the report according to the scientist's assessment of the media, or the information released according to the government carries on the report, narrow the information asymmetry. Only everybody walks to a common direction, probably guide consumers correctly.
