眼针疗法对腹泻型肠易激综合征模型大鼠结肠神经激肽1表达的影响

目的探讨眼针疗法对腹泻型肠易激综合征(D-IBS)的治疗作用及机制。方法将40只Wistar大鼠随机分为4组,对照组、模型组、匹维溴铵组和眼针组,每组10只。采用慢性应激结合束缚方法建立D-IBS模型,眼针组采用眼针治疗,针刺下焦区、大肠区、肝区、脾区;匹维溴铵组用匹维溴铵灌胃治疗,两组均治疗7天。HE染色观察结肠组织病理学变化;实时定量PCR测定结肠组织神经激肽1(NK1)的mRNA表达变化;免疫组化法测定结肠组织NK1的蛋白表达变化。结果各组大鼠结肠组织病理学无差异。与对照组比较,模型组结肠组织中NK1的mRNA表达水平显著升高(P<0.01);与模型组比较,眼针组结肠组织中NK1的mRNA表达水平显著降低(P<0.01);与模型组比较,匹维溴铵组结肠组织中NK1的mR-NA表达水平无统计学意义(P>0.05)。NK1免疫反应阳性细胞在结肠黏膜层、腺腔内、肌间神经丛、黏膜下神经丛等部位。与对照组比较,模型组结肠组织中NK1的蛋白表达水平显著升高(P<0.05);与模型组比较,眼针组和匹维溴铵组结肠组织中NK1的蛋白表达水平显著降低(P<0.05)。结论眼针能够降低D-IBS模型大鼠结肠组织中NK1的表达,从而对D-IBS起到治疗作用。

Effect of Eye-acupuncture Therapy on Expression of Colic Neurokininl of Diarrhea Irritable Bowel Syndrome Model Rats

Objective To explore the effect and functional mechanism of eye-acupuncture therapy on the diarrhea irritable bowel syndrome(D-IBS).Methods Forty Wistar rats were randomized into four groups,control group,model group,pinaverium bromide group,and eye-acupuncture group,with 10 in each.We used chronic stress in combination with binding to make D-IBS models.The eye-acupuncture group was treated with eye-acupuncture at the auricular points Lower-jiao,Large intestine,Liver,and Spleen,and the pinaverium bromide gr...
