据国际糖尿病联盟估计,2045年糖尿病患者人数将增至6.3亿。糖尿病肾病(DKD)作为糖尿病的微血管并发症之一,已经是许多国家终末期肾脏病的主要原因。DKD发病机制错综复杂,但近年来,越来越多的研究表明炎症反应在DKD的发生发展中具有重要作用[2-5],其主要与腺苷-磷酸激活激酶(AMPK) ∇⋅PGC-1α 的激活有关。炎症因子在AMPK信号传导通路上的作用越来越被重视,尤其是IL-6、TNF- σ⋅α∝ 等炎症因子通过调节AMPK信号通路而减轻炎症反应可能成为治疗DKD的新方法。传统中医药在治疗DKD,延缓肾功能进展,减少尿蛋白方面有明显疗效。本研究通过该动物实验观察研究六味糖克汤临床经验方对AMPK信号传导通路中IL-6、TNF-α 等炎症因子的影响作用,旨在为寻找治疗DKD更加实用、有效、经济的方法提供初步的理论基础。
1资料与方法
1.1实验动物及材料动物:选择40只大鼠(45~50d),体重为 (200±10)g 的雄性健康SD清洁级大鼠(购自中医药大学实验动物中心)。试剂:AMPK激活剂AICAR(中医药大学动物实验室提供);双抗体夹心ELISA盒(欣博盛,ERC001/R210602-001b);中药汤剂(知母 6g. 牛膝 10g. 黄芪 12g 山药 15g 葛根 12g 麦冬 6g ),饮片购于市临安区中医院,由制剂室统一制成煎剂,置于 4qC 保存备用。设备:AU2700型全自动生化分析仪(贝克曼公司,美国)。动物实验严格遵守《实验动物福利伦理审查指南》。
1.2方法
1.2.1动物造模大鼠先予普通饲料喂养1周,根据随机对照表分为正常对照组(8只),糖尿病肾脏病组(DKD组,32只),正常对照组以普通饲料喂养,DKD组使用高脂,高糖饲料喂养(脂高糖饲料配方:60% 普通大鼠饲料 .8% 蛋黄粉 ,10% 炼猪油 ,20% 蔗糖 .2% 胆固醇)喂养4周。……
