Stannous oxalate: An efficient catalyst for poly(trimethylene terephthalate) synthesis

Science China Chemistry 2008年第3期51卷 257-262页

作者： JIA ShuYong REN YuRong ZHANG Dan hu jing ZENG yi WANG Gongying Chengdu Institute of Organic Chemistry Chinese Academy of SciencesChengdu 610041China College of Chemistry Jilin Normal UniversitySiping 136000China Changzhou Institute of Chemistry Changzhou 213164China Graduate University of Chinese Academy of Sciences Beijing 100039China

A complete study on the catalytic activity of stannous oxalate for poly(trimethylene terephthalate) (PTT) synthesis via esterification method is carried out by comparison to the well known catalysts (tetrabutyl titanate (TBT), dibutyltin oxide (Bu2SnO), and stannous octoate (SOC)). Their catalytic activity in the esterification process is monitored by measuring the amount of water generated, while intrinsic viscosity (IV) and content of terminal carboxyl groups (CTCG) are used as the index in the polycondensation process. Stannous oxalate shows higher activity than the other catalysts. Decrease in reaction time and improvements in PTT property are observed. The higher catalytic activity of stannous oxalate is attributed to its chelate molecular structure.

Objective This study aimed to evaluate the effects of in-utero exposure to HIV and ART on pregnancy outcome and early growth of *** This cohort study enrolled 802 HIV-infected pregnant women between October 2009 and May 2018 in Guangzhou, China. The women were assigned to receive combination ART(c ART) or mono/dual ART or no treatment. The primary outcomes were the combined endpoints of any adverse pregnancy outcome [including ectopic pregnancy, spontaneous abortion, stillbirth, preterm birth, small for gestational age(SGA)] and adverse early growth outcome(including infant death, HIV infection of mother-to-child transmission, and underweight, wasting and stunting of infants at 4 weeks of age).Results Adverse pregnancy outcomes occurred in 202(35.1%) of all enrolled HIV-infected women, and121(31.3%) of all infants exhibited adverse effects on early growth at 4 weeks of age. The rates of adverse pregnancy outcomes, spontaneous abortion, ectopic pregnancy, stillbirth, infant death and perinatal HIV infection were higher among women not receiving ART, compared to those treated with c ART or mono/dual ART(P < 0.05). However, women treated with c ART had a higher rate of SGA,compared to untreated women(P < 0.05). No differences in early infant growth were observed among the different treatment *** Our findings underscore the essentiality of prioritizing HIV-positive pregnant women for ART, as even mono/dual ART available in resource-limited countries could improve pregnancy outcomes and infant survival.

Current status of severe fever with thrombocytopenia syndrome in China

Virologica Sinica 2017年第1期32卷 51-62页

作者： Jianbo Zhan Qin Wang jing Cheng Bing hu jing Li Faxian Zhan yi Song Deyin Guo Wuhan University School of Basic Medical Sciences Wuhan 430072 China hubei Provincial Center for Disease Control and Prevention Wuhan 430079 China Chinese Center for Disease Control and Prevention Beijing 102206 China Wuhan University of Science and Technology Wuhan 430081 China

Severe fever with thrombocytopenia syndrome （SFTS） is an emerging infectious disease caused by SFTS virus （SFTSV）. SFTSV is associated with a high mortality rate and has been reported in China, South Korea and Japan. SFTSV undergoes rapid changes owing to evolution, gene mutations, and reassortment between different strains of SFTSV. In this review, we summarize the recent cases and general properties of SFTS, focusing on the epidemiology, genetic diversity, clinical features, and diagnostics of SFTSV in China. From 2010 to October 2016, SFTS cases were reported in 23 provinces of China, with increased numbers yearly. Infection and death cases are mainly found in central China, where the Haemaphysalis Iongicornis ticks are spread. The national average mortality rate of SFTS infection was 5.3%, with higher risk to elder people. The main epidemic period was from May to July, with a peak in May. Thus, SFTS reminds a significant public health problem, and development of prophylactic vaccines and effective antiviral drugs will be highly needed.

Preparation and Characterization of Poly(γ-glutamic acid) Hydrogels as Potential Tissue Engineering Scaffolds

Chinese Journal of Polymer Science 2014年第11期32卷 1507-1514页

作者： Wen Zeng Wei-kang hu Hao Li yi-han jing hua Kang Qing Jiang 张超 School of Engineering Sun Yat-sen University

In this paper, methacrylated γ-PGA（m PGA） precursor was synthesized via reaction between γ-PGA and glycidyl methacrylate（GMA）. Hydrogels from this precursor were prepared under 365 nm ultraviolet irradiation. The swelling behavior and mechanical properties were studied in detail as functions of the degree of substitution（DS）, precursor concentration, and environmental p H. Results showed that the crosslink density, swelling kinetics and mechanical properties of the hdyrogel could be tailored by adjusting the DS and concentration of the precursor as well as the environmental p H. Three-dimensional photo-encapsulation of swine cartilage chondrocytes and Live/Dead assay proved the cytocompatibility of the hydrogel.
