  • 简介:目的:观察针灸对溃疡性结肠炎(ulcerativecolitis,UC)大鼠结肠黏膜胰岛素样生长因子1(insulin-likegrowthfactor-1,IGF-1)和细胞因子信号转导抑制因子-2(suppressorofcytokinesignaling,SOCS2)表达的影响,探讨针灸治疗UC的作用机理。方法:将大鼠随机分为正常组、模型组、隔药灸纽和电针组,每组8只,采用免疫学方法加局部刺激制备UC大鼠模型。隔药灸组和电针组分别进行隔药灸和电针治疗,每目1次,连续治疗14d。光镜观察大鼠结肠黏膜形态学变化,采用PAS—AB、HID—AB染色观察结肠黏膜粘蛋白,免疫组织化学技术检测大鼠结肠黏膜IGF-1和SOCS2表达。结果:光镜下可见UC大鼠结肠溃疡形成和炎症,结肠黏膜粘蛋白减少(P〈0.01),IGF-1表达升高(P〈0.01),SOCS2表达降低(P〈0.01);隔药灸、电针治疗后,结肠黏膜病理损伤减轻,粘蛋白增加(P〈0.01),IGF-1表达降低(P〈0.01),SOCS2表达升高(P〈0.01)。结论:UC大鼠结肠黏膜粘蛋白分泌减少,IGF-1表达升高、SOCS2表达下降;隔药灸、电针能改善UC大鼠结肠黏膜损伤,调节结肠粘蛋白的分泌及IGF-1和SOCS2的表达。
