摘要：

目的:探讨Peroxiredoxin 6(Prx 6)在电针预处理诱导的SD大鼠脑缺血耐受中的作用。方法:健康雄性SD大鼠80只,随机分为4组:假手术组(Sham组,n=16)、单纯电针组(Electro acupuncture组,EA组,n=16)、局灶性脑缺血再灌注组[通过大脑中动脉栓塞制作脑缺血再灌注(middle cerebral artery occlusion,MCAO)模型,MCAO组,n=32],其中2、6、12、24、48 h各4只和电针预处理组(EA+MCAO组,n=16)。通过梗死容积及神经功能评分(Garcia评分)评价脑损伤程度;通过Western Blot检测Prx 6在脑缺血再灌注后的表达水平;通过Western Blot和免疫组织化学染色法检测电针预处理对Prx 6表达的影响。结果:与MCAO组相比,EA+MCAO组梗死容积减少,神经功能评分显著改善(P<0.05);与Sham组相比,Prx 6在MCAO模型后再灌注24 h时表达最高(P<0.05);与Sham组相比,再灌注后24 h时MCAO组Prx 6表达水平升高(P<0.05);与MCAO组相比,再灌注后24 h时EA+MCAO组Prx 6的表达水平进一步升高(P<0.05)。结论:电针预处理通过促进缺血再灌注后Prx 6的表达升高而发挥脑保护作用。
