1人类血压测量方法:美国心脏协会科学声明显示文摘准确的血压测量对高血压诊断与治疗至关重要。该文是美国心脏协会关于人类血压测量的最新科学声明。业已证实,在诊室许多电子血压计可以准确测量血压,同时减少与听诊法有关的人为误差。即使没有一个观察者在场,全自动电子血压计也可以通过多次测量提供较听诊法更准确的血压测量值。研究表明诊室外所测血压与诊室血压比较存在实质性差别。目前认为动态血压监测是诊室外血压评估的参考标准,当动态血压监测不可行或患者不能耐受时,家庭血压监测则是一个替代方法。赵狄(摘译) 练桂丽(审校) Muntner P Shimbo D Carey RM Charleston JB Gaillard T Misra S Myers MG Ogedegbe G Schwartz JE Townsend RR Urbina EM Viera AJ White WB Wright JT Jr 2019中华高血压杂志2019,27,6:16
2中美垃圾场渗滤液中的金属成分变化的调研显示文摘主要对2000~2004年美国佛罗里达州中部的5个垃圾场中垃圾渗滤液的金属离子成分进行统计分析,从中发现锑(Sb)、砷(As)、铬(Cr)、铁(Fe)、镍(Ni)、钠(Na)、钒(V)、硒(Se)等8种金属在渗滤液中的质量浓度超过EPA地表及饮用水标准,其中比较严重的是As,Fe和Na,每年都超EPA标准。推测该地区地表或地下水体被As,Fe,Na污染的可能性很大。对其他还未列入监控标准的金属也做了来源及危害分析。同时与国内某垃圾场渗滤液中的金属成份进行了比较,结果显示该垃圾场渗滤液只有汞(Hg)超国家Ⅴ类水体标准,但还在美国EPA容许范围内。刘芳 徐期勇 TOWNSEND T G 2010环境科技2010,23,5:3
