[quick news] air pollution or increased risk of early pregnancy abortion on October 15, 2019

Air pollution or increased risk of miscarriage in early pregnancy poor air quality is one of the main factors leading to the disease A large number of studies have shown that the exposure of mothers to polluted air will increase the risk of childbirth and may affect the health of mothers during pregnancy or even for life However, little is known about the relationship between early pregnancy abortion and air pollution Zhang Liqiang, a professor at Beijing Normal University, and his collaborators analyzed the clinical records of more than 250000 pregnant women in Beijing over the past 10 years and found that air pollution exposure was related to the increased risk of missed abortion during pregnancy The results were published in nature sustainability on October 14 "The significance of this study is to remind pregnant women to consciously take some protective measures On the other hand, we hope that people will take more active measures to improve air quality and better protect their health " Zhang Liqiang said Https://www.nature.com/articles/s41893-019-0387-y the separation and preparation of High-Purity Ethylene has changed from "three steps" to "one step" Recently, Chen Kaijie, a professor of the school of science of Northwest Polytechnic University, published a research paper in science, indicating that they have used three kinds of metal organic frameworks (MOFs) for the first time in the world ）In the condition of four component gas mixture, high purity ethylene can be prepared by one-step separation Chen Kaijie's team found that acetylene, ethane and carbon dioxide can be removed in a single adsorption column by three MOF materials in series, so as to realize one-step separation and collection of High-Purity Ethylene (> 99.9%) at the end of the adsorption column The "porous materials" they used are porous crystal materials with three-dimensional ordered arrangement of atoms formed by metal ions and organic small molecules through coordination bonds This physical adsorption separation process can be carried out at room temperature, which can greatly reduce the energy consumption of ethylene separation process, and provide a new design idea for the research and development of green low energy consumption process in complex industrial separation system Https://science.sciencemag.org/content/366/6462/241.full: Chinese researchers find the treatment way of fever with thrombocytopenia syndrome Recently, Peng Ke's group and Xiao Gengfu's group of Wuhan Institute of Virology (biosafety research center) of Chinese Academy of Sciences and Liu Wei's group of Chinese Academy of Military Medical Sciences jointly tackle key problems, and found that the calcium channel inhibitor benidi can significantly inhibit the invasion of fever with thrombocytopenia syndrome virus and the replication of virus genome at the cell level The team carried out a retrospective study on the clinical big data of patients with fever and thrombocytopenia syndrome, and for the first time revealed that nifedipine can inhibit the replication of fever and thrombocytopenia syndrome virus in patients, and the mortality caused by virus infection decreased from 19.7% to 3.6% At present, relevant research results have been published online in the international academic journal Cell Research Http://www.xinhuanet.com/tech/2019-10/13/c_.htm nano reactor has a high mortality rate of "fast quasi stable" pancreatic cancer detection in the United States, up to 98% Effective early diagnosis can improve the 5-year survival rate of pancreatic cancer to 67% However, at present, the screening of pancreatic cancer can only detect CA19-9 and other specific protein biomarkers in the blood, only about 30% specificity can be found How to solve the problems of long time, poor specificity and early accurate detection of pancreatic cancer in clinical detection has attracted academic attention After years of research, Liu Jian, researcher team of Dalian Institute of Chemical Physics, Chinese Academy of Sciences, and Qian Kun, researcher team of Shanghai Jiaotong University, creatively proposed to apply multifunctional silica platinum based nanoreactor to pancreatic cancer detection The detection results show that the specificity of the detected markers is as high as 92%, realizing the immediate detection and molecular typing of metabolites, which not only provides new ideas for the application of nano reactor in medical diagnosis, but also provides new insights for the metabolic changes of pancreatic cancer patients, and provides potential for the accurate diagnosis of the disease Relevant research has been published in the journal matter Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2019-10 / 15 / content_ HTM? Div = - 1 researcher Xu Guowang of Dalian Institute of chemical and physical sciences was selected as the "world's most influential 100 analysis scientists" in 2019 Recently, researcher Xu Guowang of Dalian Institute of chemical and physical sciences of Chinese Academy of Sciences was selected as the "world's most influential 100 analysis scientists" in 2019 The list was selected by the British magazine the analytical scientist based on nominations from all over the world, with four Chinese analytical scientists on the list Nearly 5 Over the years, Xu Guowang's team has made many innovative research results in the separation and analysis of complex systems such as metabonomics: it has developed a super sensitive and high coverage metabonomics quantitative and qualitative comprehensive technology system suitable for precision medicine research, built an international advanced platform for metabonomics analysis, and established a series of new multi-dimensional chromatography-mass spectrometry with high sensitivity and high coverage Analytical methods; the first new strategy of targeted metabonomics in the world; independent construction of the largest domestic LC MSN metabonomics intelligent database http://news.sciencenet.cn/sbhtmlnews/2019/10/350191.shtm
