| 1 | Electrocatalytic degradation of pesticide micropollutants in water by high energy pulse magnetron sputtered Pt/Ti anode显示文摘The increasing occurrence of pesticide micropollutants highlights the need for innovative water treatment technologies,particularly for small-community and household applications.Electro-oxidation is being widely studied in this area,unfortunately,safe,stable and efficient electrocatalytic anodes without released heavy metal ions are still highly required.In this study,we fabricated a Pt/Ti anode by high energy pulse magnetron sputtering(HiPIMS-PtTi)which was used to decompose dichlorvos(DDVP)and azoxystrobin(AZX)in water.The results show that the reaction rate constant(kENR)on HIPIMS was 35.7 min-1(DDVP)and 41.3 min-1(AZX),respectively,superior to electroplating Pt/Ti anode(EP-PtTi).The identification of radicals(^(·)OH,^(1)O_(2),^(·)O_(2)-)and micro-area analyses evidenced that Pt atoms were embedded into the TiO_(2) lattice on the surface of Ti plate by high-energy ions,which resulted in more adsorbed hydroxyls,and higher production of·OH under polarization conditions.Besides,the electro-oxidation intermediates of DDVP and AZX were identified and the degradation pathways were speculated:(1)indirect oxidation dominated by·OH attack,and(2)direct electron transfer reaction of pesticides on the anode surface.The cooperated reactions achieve the complete degradation and highly efficient mineralization of DDVP and AZX. | Yuxin Zeng Siyao Zhang Lifeng Yin Yunrong Dai | 2022 | Chinese Chemical Letters2022，33，12： | 1 |
| 2 | The advantages of penehyclidine hydrochloride over atropine in acute organophosphorus pesticide poisoning:A meta-analysis显示文摘Background:Penehyclidine hydrochloride(PHC)has been used for many years as an anticholinergic drug for the treatment of acute organophosphorus pesticide poisoning(AOPP).The purpose of this meta-analysis was to explore whether PHC has advantages over atropine in the use of anticholinergic drugs in AOPP.Methods:We searched Scopus,Embase,Cochrane,PubMed,ProQuest,Ovid,Web of Science,China Science and Technology Journal Database(VIP),Duxiu,Chinese Biomedical literature(CBM),WanFang,and Chinese National Knowledge Infrastructure(CNKI),from inception to March 2022.After all qualified randomized controlled trials(RCTs)were included,we conducted quality evaluation,data extraction,and statistical analysis.Statistics using risk ratios(RR),weighted mean difference(WMD),and standard mean difference(SMD).Results:Our meta-analysis included 20,797 subjects from 240 studies across 242 different hospitals in China.Compared with the atropine group,the PHC group showed decreased mortality rate(RR=0.20,95%confidence intervals[CI]:0.16–0.25,P<0.001),hospitalization time(WMD=-3.89,95%CI:-4.37 to-3.41,P<0.001),overall incidence rate of complications(RR=0.35,95%CI:0.28–0.43,P<0.001),overall incidence of adverse reactions(RR=0.19,95%CI:0.17–0.22,P<0.001),total symptom disappearance time(SMD=-2.13,95%CI:-2.35 to-1.90,P<0.001),time for cholinesterase activity to return to normal value 50–60%(SMD=-1.87,95%CI:-2.03 to-1.70,P<0.001),coma time(WMD=-5.57,95%CI:-7.20 to-3.95,P<0.001),and mechanical ventilation time(WMD=-2.16,95%CI:-2.79 to-1.53,P<0.001).Conclusion:PHC has several advantages over atropine as an anticholinergic drug in AOPP. | Siyao Zeng Lei Ma Lishan Yang Xiaodong Hu Cheng Wang Xinxin Guo Yi Li Yi Gou Yao Zhang Shengming Li Shaotong Zhang Xiaoxuan Wu Meihong Li Jing Lei Bingqian Li Chengfei Bi Like Ma Qingpeng Luo | 2023 | Journal of Intensive Medicine2023，3，2： | 0 |
| 3 | A Two-dimensional Dual-pore Covalent Organic Framework for Efficient Iodine Capture显示文摘Effectively capturing volatile radioiodine generated during the nuclear fission process is considered to be a safe way to the utilization of nuclear power. Here we report a new two-dimensional covalent organic framework(2D COF), ETTA-PyTTA-COF, as a highly efficient iodine adsorbent, which is constructed through the condensation reaction between 4,4’,4’’,4’’’-(ethene-1,1,2,2-tetrayl)-tetrabenzaldehyde(ETTA) and 1,3,6,8-tetrakis(4-aminophenyl)pyrene(PyTTA). The ETTA-PyTTA-COF possesses a permanent 1D channel porous structure with a high Brunauer-Emmet-Teller(BET) surface area of 1519 m2/g and excellent chemical and thermal stability. It shows ultrahigh iodine adsorption capability, which can reach up to 4.6 g/g in vapor owing to its high BET surface area, large π-conjugated structure and plenty of imine groups in the skeleton of the COF as effective iodine sorption sites. | WEN Zhongliang WANG Shenglin FU Siyao QIAN Jiaying YAN Qianqian XU Huanjun ZUO Kaiming SU Xiaofang ZENG Chaoyuan GAO Yanan | 2022 | Chemical Research in Chinese Universities2022，38，2： | 0 |
| 4 | Role of hemoperfusion combined with hemodialysis in acute severe organophosphorus pesticide poisoning:a meta-analysis显示文摘Background:Acute severe organophosphorus pesticide poisoning is a common severe emergency in developing countries.Our meta-analysis aimed to clarify the efficacy of hemoperfusion combined with hemodialysis on acute severe organophosphorus pesticide poisoning.Methods:Several databases were searched.After formulating relevant inclusion and exclusion criteria,qualified studies were included,and the data were extracted.The outcome indicators were the success rate of rescue,the time of hospitalization,the incidence of com-plications,the time for the cholinesterase level to return to normal,the coma time,and the atropine dosage.The results were analyzed using risk ratios,weighted mean difference,standard mean difference,and 95%confidence interval.The Cochrane Collaboration tool was used to assess the risk of bias in all the included studies.In terms of statistical methods,we used RevMan software(version 5.3;The Nordic Cochrane Centre,The Cochrane Collaboration,Copenhagen,Denmark)and Stata(versions 14 and 16;StataCorp,College Station,TX,USA)for the data analysis.Results:We included 92 randomized controlled trials with 6899 participants.Compared with the conventional emergency treatment group(CET group),the hemoperfusion group(HP+CET group),and the hemodialysis group(HD+CET group),the use of hemoperfusion combined with hemodialysis based on CET(HP+HD+CET group)significantly increased the success rate of rescue and reduced hos-pitalization time,the incidence of complications,time for cholinesterase level to return to normal,coma time,and atropine dosage.Conclusion:Hemoperfusion combined with hemodialysis is effective in the treatment of acute severe organophosphorus pesticide poi-soning.In the future,more scientifically designed,large-scale,high-quality,multicenter randomized controlled trials are needed to validate this study further. | Siyao Zeng Lei Ma Lishan Yang Xiaodong Hu Cheng Wang Yi Gou Yi Li | 2023 | Emergency and Critical Care Medicine2023，3，4： | 0 |
