1环形扩散管和滤膜联用采集和测定大气中气固相物质显示文摘建立了环形扩散管(annular diffusion denuder)和滤膜连用的采样装器。采用涂渍1%碳酸钠甲醇水溶液和5%亚磷酸甲醇溶液的两段环形扩散管串联分别收集气态HNO_3,HCl,SO_2和NH_3、空气经扩散管后,继而抽入滤膜采样头,用Teflon滤膜采集颗粒物,Nylon滤膜收集由Teflon滤膜上颗粒物挥发产生的气态HNO_3和HCl。样品提取后,用离子色谱法测定SO_4^(2-),NO_3^-和Cl^-;采用流动注射荧光法测定NH_4^+。当采样流速为10L/min,采样24h,环形扩散管对气态硝酸、氯化氢和二氧化硫的检出限(3σ)为0.04—0.09μg/m^3,对氨的检出限为0.12μg/m^3。实验结果表明本法适用于大气和室内空气的采样和测定。黎源倩 Harrison R M 1992环境化学1992,11,1:5
2化学气体污染突发事件中的人群疏散:横断面调查显示文摘目的比较一个塑料工厂发生化学事故后躲藏和被疏散人群的健康结局。设计横断面调查。背景英格兰西南的市区。研究对象该地区1750位曾暴露于化学烟雾的居民,其中472人被疏散,剩下的1278人被建议躲藏在室内。主要结局测定不利于健康的症状数目。出现4个或以上症状者被确定为一个病例。主要的结果1096位居民(63%;299人被疏散,797人躲藏起来)为本分析提供了资料。被疏散人群的平均症状分值和病例的比例比躲藏人群的要高(疏散者:症状分值1.9,病例比例19.7%(n=59);躲藏者:症状分值1.0,病例比例9.5%(n=76),二者比较P<0.001)。在事故发生后两周末时二组间的差异明显变小。成为病例的两个主要可变更危险因子是疏散(比值比2.5,95%可信区间1.7~3.8)和在事故当天直接暴露于烟雾的时间超过2小时(比值比2.0,95%可信区间1.7~2.3)。住所距工厂的距离或是干预前(头6个小时)暴露的水平对于研究对象成为病例的作用不大。结论在此次化学事故中躲藏起来可能是优于疏散人群的保护措施。这与专家们普遍认为的观点一致。尽管本研究有一定的局限性,但它是基于一场真实的事件。疏散本身有一定的风险和资源上的限制,认识上的增加可能会有助于减少将来不必要的疏散。S Kinra G Lewendon R Nelder N Herriott R Mohan M Hort S Harrison V Murray 陈雷(译) 2005英国医学杂志中文版2005,8,5:3

4Acute ischaemic stroke interventions: large vessel occlusion and beyond显示文摘Care for acute ischaemic stroke is one of the most rapidly evolving fields due to the robust outcomes achieved by mechanical thrombectomy.Large vessel occlusion(LVO)accounts for up to 38%of acute ischaemic stroke and comes with devastating outcomes for patients,families and society in the pre-intervention era.A paradigm shift and a breakthrough brought mechanical thrombectomy back into the spotlight for acute ischaemic stroke;this was because five randomised controlled trials from several countries concluded that mechanical thrombectomy for acute stroke offered overwhelming benefits.This review article will present a comprehensive overview of LVO management,techniques and devices used,and the future of stroke therapy.In addition,we review our institution experience of mechanical thrombectomy for posterior and distal circulation occlusion.Ahmad Sweid Batoul Hammoud Sunidhi Ramesh Daniella Wong Tyler D Alexander Joshua Harrison Weinberg Maureen Deprince Jaime Dougherty Dimitri Jean-Mickael Maamari Stavropoula Tjoumakaris Hekmat Zarzour Michael R Gooch Nabeel Herial Victor Romo David M Hasan Robert H Rosenwasser Pascal Jabbour 2020Stroke & Vascular Neurology2020,5,1:2
