[quick news] on November 6, 2019, Chinese scientists revealed the key process of primate embryo early development

A research team of Chinese Academy of Sciences recently completed a project to reproduce the gastrogenesis of non-human primate embryos in vitro, which established an important research foundation for the study of primate early embryonic development The results have been published online in the internationally renowned academic journal Science The research, carried out by the Institute of zoology, Chinese Academy of Sciences, Kunming Institute of zoology and the Institute of stem cells and regenerative medicine innovation, has established a new in vitro culture system, which can support the development of cynomolgus monkey embryos for up to 20 days after fertilization The structure, cell and molecular level of embryos cultured in vitro fully reflect the key events of early development in vivo after implantation, and the development reaches the stage of gastrulation Http://bjrb.bjd.com.cn/html/2019-11/05/content_.htm "open" practice stimulates research and back feeding teaching In many people's eyes, there are some "contradictions" in the period of president of Local Newly-built Undergraduate Colleges For example, for a long time, as a teaching-oriented college, teaching and scientific research are "stereotyped"; most of them are non master's units, which are prone to produce structural contradictions between the growth of teachers' demand for scientific research and innovation and the lack of students; more importantly, at the student level, the contradiction between students' desire for knowledge of new things and new technologies and the traditional indoctrination teaching mode More and more prominent, the school as a whole is lack of innovative teaching system to comprehensively improve students' innovative thinking ability Zheng Zhi, director of Henan Key Laboratory of micro nano energy storage and conversion and vice president of Xuchang college, led the establishment of the first Research Institute of Xuchang college, surface micro nano materials research institute After the establishment of the Research Institute, a group of doctors and researchers with strong scientific research ability were introduced quickly, and some characteristics were gradually condensed in the basic and Application Research of nanotechnology and clean energy Http://paper.jyb.cn/zgjyb/html/2019-11/04/content 572086.htm? Div=-1 biological 3D printing technology is expected to serve precision medicine in October this year The new craniomaxillofacial repair system developed by Guangzhou Maipu company has been approved by the State Food and drug administration This high-end implant innovative medical equipment product has been approved by the State Food and drug administration, and has been in the global market for 60 years The use of hospitals in many countries and regions has completely subverted the image of "low-end low price" of Chinese medical products Guangzhou Maipu regenerative medical technology Co., Ltd is the first high-tech enterprise in China that applies the biological 3D printing technology to develop implanted medical devices and carry out precision medical services In the exhibition hall of this enterprise, the world's first bio 3D printing artificial dura product developed in China is displayed It looks like a tissue, but it is a new degradable material used to replace the meninges needed for craniotomy Guan Zhiyong, general manager of research and development of Shenzhen Mindray medical center, said that in terms of the per capita consumption of drugs and medical devices, the ratio of drugs to devices in China is about 1 to 0.351, far higher than 1 to 0.98 in developed countries Compared with the international market, China's medical device market has a huge growth space Http://www.xinhuanet.com/politics/2019-11/03/c_.htmchinese plan will become the highest international standard for the treatment of cerebrovascular diseases in the future The treatment of cerebrovascular diseases in Europe and America will also be the first one in China Recently, the National Clinical Research Center for nervous system diseases announced that the treatment of cerebrovascular disease "chance" initiated by Professor Wang Yongjun of Beijing Tiantan Hospital Affiliated to Capital Medical University The program "has been listed as the highest level evidence in the world by the world recognized guidelines for the management of cerebrovascular diseases in China, the United Kingdom, Canada and the United States, and has become the international gold standard for the treatment of this disease "Drug gene testing is the next high ground for us to break through." "At present, the world's first phase III clinical trial of cerebrovascular disease based on drug gene detection -- chance-2 has been launched," Wang Yongjun said Wang Yongjun is leading the team to explore another "bypass gene" technology "In the emergency department, we first tested the gene of the patients with acute cerebrovascular disease For the patients with CYP2C19 gene slow metabolism, we will choose the drug tegrarol combined with aspirin to replace them."
