摘要：

目的:探讨远程缺血预处理后,急性脑卒中24 h,72 h时脾脏组织Treg cells水平的表达变化,阐述远程缺血预处理对Treg cells的调节及其在急性脑卒中缺血期的保护作用。方法:60只昆明小鼠随机分为3组,sham组、MCAO组、远程缺血预处理+MCAO组(n=20只/组),建立小鼠MCAO模型,缺血60分再灌注后在24 h,72 h时进行神经功能缺陷评分(NDS),随后处死小鼠行氯化三苯基四氮唑(TTC)脑片染色,观察脑梗死容积变化。运用流式细胞仪检测脾脏组织Treg cells的表达。ELISA检测脑组织中炎症因子IFN-γ的表达。结果:在72 h时远程缺血预处理组与对照组相比,脑梗死容积减少,神经障碍减轻,脾脏Treg cells的表达上升,脑组织炎症因子IFN-γ的表达下降,P<0.05,而24 h Treg cells的表达水平并未发生明显变化,P>0.05。结论:在脑卒中急性期,远程缺血预处理通过升高Treg cells的表达参与脑保护作用。
