| 摘要: |
| [目的] 检测脑缺血再灌注模型早期梗死灶边缘区Toll样受体9（TLR9）、肿瘤坏死因子-α（TNF-α）、干扰素调节因子7（IRF7）、干扰素-β（IFN-β）的mRNA表达，阐明针刺对脑梗死的TLR9通路作用机制。[方法] 使用线栓法制作大鼠大脑中动脉闭塞（MCAO）脑缺血模型，缺血90 min后行再灌注，治疗组予针刺干预，于再灌注6 h、5 d后将大鼠取材，进行荧光定量聚合酶链反应（RT-PCR）法检测，观察局灶性脑缺血模型大鼠脑组织TLR9、TNF-α、IRF7、IFN-β的mRNA表达及针刺的干预作用。[结果] 针刺能明显增强神经保护因子IFN-βmRNA的表达（P<0.05）。TLR9信号通路mRNA的表达对比均无统计学差异（P>0.05）。[结论] 本针刺法治疗脑梗死通过增强神经保护因子IFN-β mRNA的表达，改善脑缺血再灌注造成的神经功能活动障碍。本研究尚不能表明该针刺法能抑制TLR9信号通路mRNA的表达。 |

| Abstract: |
| [Objective] To observe the intervention effect of mRNA signaling pathway acupuncture therapy on cerebral ischemia reperfusion model of early TLR9, the infarct marginal zone TNF-α, IRF7, IFN-β; elucidating the mechanism of acupuncture treatment of cerebral infarction. [Methods] Use line plug method cerebral artery occlusion (MCAO) on rat cerebral ischemia model, ischemia reperfusion after 90 min, acupuncture group of rats received intervention of acupuncture method after reperfusion 6 h, 5 d, the rats were decapitated, fluorescence quantitative polymerase chain reaction (RT-PCR) assay, to observe the odel of focal cerebral ischemia in rat brain TLR9, TNF-α, IRF7, IFN-β mRNA expression and intervention effect of acupuncture. [Results] This acupuncture method can obviously enhance the nerve protection factor IFN-βmRNA expression (P<0.05). [Conclusion] This acupuncture can treat of cerebral infarction by increasing nerve protection factor IFN-βmRNA expression, reducing the number of neurons injury, enhancing the capacity of brain tissue repair, and improving cerebral ischemia reperfusion injury of nerve function activities obstacles. This reserch cannot indicate the treatment could inhibition the mRNA expression of TLR9 pathway. |
