[quick news] 3D printed skulls on September 17, 2019: basic research, new materials, and high technology are indispensable

3D printing skull: basic research, new materials and high technology are the same When accidents cause skull defects, how can we repair the skull? On September 15, at the 3D printing and advanced new material innovation application forum held in Jinan, this was a scene mentioned by all the big coffee exchanges This forum, sponsored by the biomanufacturing industry working group of China additive manufacturing industry alliance and neurosurgery of Shandong Provincial Hospital, attracted the participation of Professor Xu Chen's team of Tsinghua University, Professor Guan Junwen of West China Hospital of Sichuan University, Professor pangqi of Neurosurgery of Shandong provincial hospital and Professor Ding Feng Experts believe that "perfect skull" can be printed out in 3D by using polymer synthetic materials; if we expect to "print" living organs for human tissue repair in the future, we still need experts in basic research, new materials and high technology to "twist a rope" and work together Http:// explore new ways to treat AIDS! The first successful transplantation of human hematopoietic stem cells with gene editing in the world September 12 The New England Journal of Medicine published the Chinese scholar's exploration of "making up for the patients in Berlin with the advantages of gene editing technology" online It is the first time in the world that CCR5 gene is inactivated in blood stem cells and the edited stem cells are transplanted into patients with HIV infection and acute lymphoblastic leukemia Gene edited hematopoietic stem cells can survive in patients and reproduce from "a few outsiders" to "an absolute majority of indigenous people", which is the key to cure AIDS Http:// as the basic unit of the brain, the three-dimensional database of the largest whole brain neurons is very important for the study of the structure and function of the brain In the past, due to the limitation of neuron labeling and imaging technology, the image has high noise and uneven signal On September 15, at the 2019 International Seminar on neuron reconstruction and application held by Southeast University, the reporter of science and technology daily learned that the Institute of brain science and intelligent technology of Southeast University and the brain data joint center of Southeast University Allen Institute have recently developed a set of open-source accurate data annotation system teravr based on VR and AI technology At the whole brain level, the world's largest and most accurate three-dimensional structure of neurons is reconstructed, with the largest amount of data in the world Http://news.scienceet.cn/htmlnews/2019/9/430596.shtm ecological environment protection should rely on scientific and technological innovation as a scientific answer and seriously respond to the concerns of the prime minister and the people At the 170th executive meeting of the State Council, it was decided to set up the prime minister's fund project, carry out the causes of air pollution and tackling key projects, and focus on tackling key problems In accordance with the "1 + X" model proposed by Minister Li Ganjie, the innovation mechanism of the Ministry of ecological environment, with the Chinese Academy of environmental sciences as the main body, cooperates with institutions directly under the Ministry of ecological environment, such as China Environmental Monitoring Center, Environmental Planning Institute, Tsinghua University, Peking University and other universities, as well as 200 scientific research institutes within the Chinese Academy of Sciences, Chinese Academy of natural sciences and National Climate Center A number of advantageous units, more than 2000 scientific researchers in the field of national atmosphere, have carried out research on the causes of heavy air pollution and tackling key problems Http:// for seven years! In 1958, the analytical work of the chemical structure of insulin won the Nobel Prize in chemistry Synthetic insulin will be a distant thing, nature said in a commentary Perhaps at the same time, the far away China has officially started the "far away" thing - synthetic insulin A few years later, the Chinese team, which is composed of Institute of Biochemistry, Institute of organic chemistry, Chinese Academy of Sciences, and Beijing University, successfully locked the "remote" into seven years Later, science published a long review of several pages entitled "insulin synthesis in Red China" For chemically synthesized peptides, "51" was an astronomical number at that time Many difficulties make this "remote" out of reach However, China has spent seven years of unremitting efforts to reach the summit of chemical synthesis through synthetic insulin http://
