动脉粥样硬化性脑梗塞和脑出血患者血浆可溶性血栓调节蛋白水平的研究

目的 探讨血浆可溶性血栓调节蛋白（Soluble thrombmodulin,sTM）与脑梗塞和脑出血患者小血管损伤、动脉粥样硬化的关系。方法 应用酶联免疫吸附方法（Enzyme-Linked Immunosorbent Assays,ELISA），检测60例脑梗塞患者、56例脑出血患者和64例健康对照的sTM水平，并分析sTM与血脂、血压的关系。结果 脑梗塞和脑出血的甘油三脂、舒张期血压明显高于对照组；脑梗塞和脑出血的高密度脂蛋白显著低于对照组；脑出血组的收缩期血压明显高于其他两组；脑梗塞的 胆固醇水平显著高于其他两组；脑出血的sTM显著高于脑梗塞和对照组，而脑梗塞的sTM显著高于对照组。sTM与总胆固醇、甘油三脂、收缩和舒张期血压水平显著正相关；sTM与高密度脂蛋白水平成显著负相关。结论 脑梗塞和脑出血存在由高血压和动脉粥样硬化导致的小血管损伤。sTM是脑卒中的独立危险因子。     

Shanghai synchrotron radiation facility

<正>Synchrotron radiation was discovered by chance at an electron synchrotron accelerator in 1947.he irst experiments applying synchrotron radiation were conducted in the early 1960s,with measurements using synchrotron radiation for standards and as a source for ultraviolet wavelength spectroscopy.Synchrotron radiation later atracted considerable interest for use in solid-state physics research.With increased development of both facilities and applications,a surge of interest in synchrotron
