1FK506对实验性卒中疗效的系统评价和Meta分析显示文摘FK506是治疗急性卒中的一种候选用药。决定一种药物是否可以用于临床试验,应当以全面的、无偏倚的动物实验数据的评估为依据,同时还应考虑到这些数据的局限性。这种评估不但应包括药物疗效,而且也应包括药效在体内的特征和局限性。本研究应用系统评价和Meta分析的方法对FK506在卒中动物模型中保护作用的证据进行评价。总共纳入了29个描述了实验步骤的研究,包括1759只动物。结果显示,FK506疗效的点估计值(结局指标的改善)是31.3%[95%CI(0.272-0.354)]。在采用氯胺酮麻醉和短暂性脑缺血的动物实验中,FK506的疗效更高,在使用大鼠,合并其他疾病的动物及仅以梗死面积为疗效指标的实验中,FK506疗效较低。已发表的实验研究质量均接近临床试验标准,但在高质量的研究中,FK506的疗效较低。FK506在实验性脑卒中的研究中,虽然显示出有明显的疗效,但是应注意由于研究质量和可能的发表偏倚等冈素的影响,FK506的疗效可能被过高估计。Malcolm R Macleod Tori O’Collins Laura L Horky David W Howells Geoffrey A Donnan 段建钢 2006中国循证医学杂志2006,6,6:3
