目的：研究电针对MCAO大鼠脑组织小胶质细胞TLR4及NF-κB蛋白表达的影响。方法建立MCAO大鼠模型，分别电针内关、曲池后进行神经体征评分，HE染色检测神经元坏死率，双重免疫荧光染色检测TLR4、NF-κB p65蛋白在小胶质细胞的表达。结果模型组与正常组比较，大鼠神经体征评分、脑海马神经元坏死率、脑组织TLR4、NF-κB p65蛋白表达均明显升高，差异有统计学意义（ P<0,01）；内关组、曲池组与模型组比较，神经体征评分、脑海马神经元坏死率、TLR4、NF-κB p65蛋白表达明显降低，差异有统计学意义（ P<0,05）；曲池组与地机组比较，脑海马神经元坏死率明显降低，差异有统计学意义（ P<0,05）；内关组与地机组比较，大鼠脑组织小胶质细胞TLR4蛋白表达明显降低，差异有统计学意义（ P<0,05）。结论电针内关、曲池能改善MCAO大鼠的神经功能损伤，抑制TLR4及NF-κB蛋白在小胶质细胞的表达，提示电针能够通过影响小胶质细胞TLR4/NF-κB信号通路的活化从而发挥脑保护作用。

Objective To investigate the effects of electroacupuncture on the protein expression of TLR4 and NF - κB p65 in microglia cells in cerebral of middle cerebral artery occlusion( MCAO)Rats, Methods After electroacupuncture on Neiguan(PC6)and Quch(i LI11)respectively,we observed neurological syndrome score of MCAO rats, The death rate of neuron were measured by HE dyeing,and the protein expression of TLR4 and NF - κB p65 in microglia cells were detected by doubling immunofluorescent staining, Results Compared to sham - operation control group,neurological syndrome score,death rate of neuron and the protein expression of TLR4 and NF - κB p65 in microglia cells were increased in model group( P < 0, 01), Compared to model group,neurological syndrome score,death rate of neuron,the protein expression of TLR4 and NF - κB p65 in microglia cells were decreased in Neiguan and Quchi group(P <0, 05), Compared to Diji group,the death rate of neuron were decreased in Quchi group(P <0, 05),and the protein expression of TLR4 in microglia cells were decreased in Neiguan group(P <0, 05), Conclusion After electroacupuncture on Neiguan and Quchi,the damage of cerebral nerve function of MCAO rats are improved,and the expression of TLR4 and NF - κB p65 in microglia cells are inhibited, It indicates that through effects on the activation of TLR4/ NF - κB signal pathway in microglia cells,electroacupuncture can play a protective role on cerebral ischemia.
