  • 简介:目的:探讨针刺对STZ糖尿病大鼠胰腺组织内质网应激IRE1-CHOP信号通路及相关凋亡基因的影响。方法:SD大鼠80只,选取10只用普通饲料喂养作为空白对照组,其余70只用高脂高糖饲料喂养和腹腔注射小剂量STZ制作糖尿病模型。造模成功30只,随机分为针刺治疗组模型对照组、和西药组(二甲双胍),每组10只。治疗4周,测大鼠的RBG,胰腺组织CHOP、IRE1、Bax、Bcl-2蛋白和mRNA表达。结果:与治疗前比较,针刺组和西药组RBG均明显降低(P〈0.05),模型组和空白组RBG变化的差异无统计学意义(P〉0.05);模型组胰腺CHOP、IRE1、Bax蛋白表达显著高于空白组(P〈0.05),针刺组和西药组显著低于模型组(P〈0.05);模型组胰腺CHOP、IREl、BaxmRNA表达显著高于空白组(P〈0.01),针刺组和西药组显著低于模型组(P〈0.01);模型组Bcl-2蛋白表达显著低于空白组(P〈O.05),针刺组和西药组显著高于模型组(P〈0.01),针刺组与西药组之间差异无统计学意义(P〉0.05);模型组Bcl-2mRNA表达显著低于空白组(P〈0.01),针刺组和西药组显著高于模型组(P〈0.01),针刺组与西药组之间差异无统计学意义(P〉0.05)。结论:STZ糖尿痛大鼠胰腺组织存在内质网应激,IRE1-CHOP信号通路是抑制胰腺内质网应激的主要通路,针刺可以通过IRE1-CHOP信号通路改善胰腺组织内质网应激,抑制凋亡基因,保护胰腺组织。
