摘　　要：目的分别观察眼针与体针疗法对缺血再灌注损伤24 h后大鼠脑组织中TNF—α表达的影响,探讨眼针与体针不同疗法对免疫效应表达的差异,为眼针疗法的临床应用提供实验依据。方法线栓法制备SD大鼠大脑中动脉梗死(middle cerebral artery occlusion,MCAO)再灌注模型。将48只SD大鼠随机分为正常对照组、体针组、模型组、假手术组、眼针穴区组与眼针穴区外组(n=8)。模型组、眼针穴区组、眼针穴区外组与体针组均采用改良的线栓法制备SD大鼠大脑中动脉梗死(middle cerebral artery occlusion,MCAO)再灌注模型。采用ZeaLonga评分法进行大鼠神经功能评分;ELISA方法检测缺血再灌注24 h后大鼠血清TNF—α含量,实时定量PCR方法检测缺血再灌注24 h后大鼠脑皮质TNF—αmRNA的表达,Western Blot法检测缺血再灌注24 h后大鼠脑皮质TNF—α蛋白的表达。结果脑缺血再灌注24 h后,眼针穴区组和体针组大鼠神经功能缺损评分均较模型组大鼠评分降低(P<0.01),但两者相比无统计学差异,眼针穴区外组大鼠评分与模型组相比较无统计学差异;眼针穴区组、体针组和和眼针穴区外组大鼠血清TNF—α含量均较模型组显著减少(P<0.01),但以眼针穴区组与体针组减少更明显,眼针穴区组与体针组比较无统计学差异;眼针穴区组、体针组和眼针穴区外组大鼠脑组织TNF—αmRNA含量和蛋白质含量均较模型组显著下调(P<0.01),眼针穴区组与体针组比较无统计学差异。结论眼针与体针在改善急性脑缺血再灌注损伤中的免疫效应相当,且两种疗法的作用机制可能均与脑组织TNF—α的表达下调有关。Objective To observe the effects of eye acupuncture and body acupuncture on tumor necrosis factor-α(TNF-α) expression in the cerebral cortex of rats after ischemia-reperfusion injury,in order to investigate the differences in therapeutic function between eye acupuncture and body acupuncture against acute cerebral ischemia-reperfusion injury. Method 48 Rats established by suture method were randomly divided into control group,sham operation group,model group,eye-acupuncture in point area group,eye-acupuncture outside point area group and body acupuncture group. After reperfusion 24 h,the neurophysical behaviours were accessed by ZeaLonga neurophysical impairment marks;the levels of plasma TNF-αwere determined by ELISA method;the expression of ischemic cerebral cortex TNF-αmRNA was measured by RT-PCR method;the expression of ischemic cerebral cortex TNF-αprotein was detected by western blot. Results After reperfusion 24 h,compared with control group,neurologic impairment marks of eye-acupuncture therapy in point area group and body acupuncture group both decreased obviously (P<0.01),however there were no significant differences between the eye-acupuncture in point area group and body acupuncture group;the levels of plasma TNF-αin rat cerebral cortex after the eye acupuncture therapy and body acupuncture therapy were obviously decreased (P<0.01),however there were no significant differences between the eye-acupuncture in point area group and body acupuncture group; the expressions of TNF-α mRNA and protein in rat cerebral cortex after the eye acupuncture therapy and body acupuncture therapy were also obviously down-regulated (P<0.01),however there were no significant differences between the eye-acupuncture in point area group and body acupuncture group.Conclusion The eye and body acupuncture therapy show the same effects on treating cerebral ischemia reperfusion. The mechanisms of these two therapies may be related to up regulating TNF-αexpression in rat cerebral cortex with ischemia-reperfusion injury.
