On the afternoon of September 29, 2017, the Jinyun Forum on Life Health and Nutrition Engineering is co-held by Chongqing University Association for Science and Technology, School of Life Science and Chongqing Nutrition Society at Lecture Hall LA101, Science Building, Huxi Campus of Chongqing University. Six scholars and experts are invited to the Forum and deliver 6 academic reports on the themes, namely “nutrition, health and innovation”. More than 200 students and teachers from the School of Life Science, the School of Bioengineering and other related schools have attended the Forum. Professor Li Zhengguo, the vice dean of the School of Life Science, and Professor Ren Maozhi, the assistant to the dean, have chaired the Forum.
Professor Lei Xingen, a scholar of the “Recruitment Program of Global Experts” of Organization Department of the Central Committee of the CPC from Cornell University, gives a brief introduction to the knowledge of selenium, a microelement. After that, he delivers a speech titled “Selenium supplementation and biofortification in China: Benefit or risk?” In the early stage of selenium research, the researchers once deemed it as toxic. Later, experiments have proved that the selenium enrichment helped with cancer treatment, and high selenium content could induce insulin resistance. Professor Lei and his experiment team have been dedicated to exploring the effecting mechanism of high selenium content on increase of blood glucose and blood fat. Furthermore, Professor Lei tells the audience that a science-based understanding of selenium is very important. Uptake of the selenium should be based on the specific physical condition and excessive selenium may do harm to our body.
Professor Zhang Huidong, one of the ten batches of experts of “Recruitment Program of Global Experts” of Organization Department of the Central Committee of the CPC from the Third Military Medical University, discusses with the attendants about the “Molecular Mechanism of DNA Damage Resulting in DNA Replication Mutation and Disorder”. DNA damage as a result of environmental pollution will lead to mutation and disorder of DNA replication and RNA transcription, which will further result in change of the protooncogene and cancer suppressor gene, and ultimately cause cancer. Researcher Li Xianliang, deputy director of the Technical Center of Chongqing Entry Exit Inspection and Quarantine Bureau, has a profound analysis of food safety concerns, including the “European” toxic eggs” event and the lessens learned from the event. Professor Li also explains the response to the event from the perspective of professional science, which has raised concern of the audience.
Director Wang Jian from the Nutrition Department of Xinqiao Hospital of the Third Military Medical University delivers a speech titled “How Far is Diabetes away from You?” The prevalence rate of diabetes in China has reached 11.6% and it ranks the 4th to the 5th place in terms of cause of death. Obesity is an independent risk factor for onset of diabetes. Therefore, the most effective way to treat and prevent diabetes is to change the diet and mode of life. The five principles and eight measures to prevent and fight against diabetes have raised interests among the teachers and students present. Doctor Wang Yi from the Technical Center of Chongqing Entry Exit Inspection and Quarantine Bureau explains the “basic information on meat import and export of Chongqing and requirements for inspection and quarantine”, and introduces the audience to the three steps taken in China to control the safety of imported and exported food. Given the “One Belt and One Road” strategy and the major deployment of the Yangtze River Economic Zone, Chongqing will combine “Cuntan Port, Airport Import and Railway Import”, so as to provide one-stop port service for import and export of meat. Associate Researcher Qiu Dan from the School of Life Science of Chongqing University delivers a speech titled “Translating Soybean functional genomics into improving human health” and explains to the audience how the soybeans would gradually become one of the main food sources to fight against hunger and how it is effected by drought and flood and plant diseases and insect pests and how scientists are eager to find a soybean type with high yield, high protein content, nematode resistance and draught and flood resistance. Doctor Qiu has selected nearly 1,000 core varieties from the 15,000 samples at the Soybean Germplasm Resource Center of the United States Department of Agriculture, and successfully found 11 key genes. This has laid a solid foundation for cultivation of soybeans resistant to nematode, draught and flood.
Vice Dean Li Zhengguo delivers a summary report on the Forum, and encourages the audience to take care of their own health, provide more scientific and technological products, and better nutrition and health services for their families, friends and the society while carrying out research and learning professional knowledge.
In addition, on the morning of September 29, Professor Lei pays a visit to the lab of the School of Life Science accompanied by related teachers of the School, and discusses with the teachers with respect to related research work.
