摘　　要：目的对比观察电针阳陵泉、上巨虚、下巨虚、足三里穴对急性胆囊炎(AC)模型豚鼠血清肿瘤坏死因子-α(TNF-α)及胆囊组织中烟碱型乙酰胆碱受体α7信使核糖核酸(nAchRα7 mRNA)表达的影响,探讨胆之下合穴阳陵泉治疗对应腑病是否存在相对特异性。方法 72只健康豚鼠随机分为空白、模型、阳陵泉、上巨虚、下巨虚、足三里组六组,12只/组,雌雄各半。除空白组外均于胆囊注射大肠杆菌建立豚鼠急性胆囊炎模型,成模后予电针治疗5 d,取胆囊组织行HE染色,镜下观察形态学变化,ELISA法检测血清TNF-α水平,RT-PCR检测胆囊nAchRα7 mRNA的表达。结果与空白组比较,HE染色镜下观察可见其他组胆囊组织出现不同程度的病理损伤,且nAChRα7mRNA表达明显降低(P<0.01),血清中TNF-α明显升高(P<0.01);与模型组比较,各电针治疗组血清TNF-α含量均明显降低(P<0.01)而胆囊nAChRα7mRNA表达均明显升高(P<0.01);与阳陵泉组比较,足三里、上巨虚、下巨组血清TNF-α含量均明显升高(P<0.01)而胆囊nAChRα7mRNA表达均明显降低(P<0.01)。结论针刺与消化系相关的内腑下合穴对AC模型豚鼠均可产生不同程度的治疗作用,其机制可能是通过调节TNF-α及nAchRα7 mRNA表达而抑制炎症因子、减轻炎症反应;对比可知,阳陵泉组的干预效应较其它治疗组突出,说明阳陵泉穴与对应胆腑之间存在相对特异性。Objective To compare the eftects of electroacupuncture at Yanglingquan, Shangjuxu, Xiajuxu, and Zusanli points on sermn tumor necrosis thetor-α （TNF-α） and mRNA expression of α7 nicotinic aeetyleholine receptor （nAChR α7） in the gallbladder in a guinea pig model of acute eholeeystitis （AC）, and to explore whether Yanglingquan, the lower He-sea point of the gallbladder, is relatively specific for treating the corresponding visceral disease. Methods Seventy-two heahhy guinea pigs were randomly and equally divided into blank group, model group, Yanglingquan group, Shangjuxu group, Xiajuxu group, and Zusanli group, with equal numbers of male and temale in each group. A model of AC was established by injection of Escherichia coli into the gallbladder of all guinea pigs except for the blank group. After model establishment, the four treatment groups received eleetroaeupuneture for 5 day-s. The gallbladder was collected for HE staining and morphological analysis by microscopy. The serum level of TNF-α and expression of nAChR α7 mRNA in the gallbladder were measm＇ed by enzyme-linked immunosorbent assay- and RT-PCR, respectively. Results Compared with the blank group, the other groups had varying degrees of pathological damages in the gallbladder according to HE staining and microscopic observation, as well as significantly lower expression of nAChR α7 mRNA and a significantly higher serum level of TNF-α （P〈0.01）. Compared with the model group, the four electroacupuncture groups had a significantly lower serum level of TNF-α and significantly higher expression of nAChR （27 mRNA in the gallbladder （P〈0.01）. Compared with the Yanglingquan group, the Shangjuxu group, the Xiajuxu group, and the Zusanli group had a significantly higher serum level of＇ TNF-α and significantly lower expression of＇ nAChR α7 mRNA in the gallbladder （P〈0.01）. Conclusion Electroacupuncture at the lower He-sea points of＇ digestion-related organs has different degrees of＇ therapeutic effects on the
