摘要 目的:观察肾安提取液对糖尿病肾病(DN)小鼠肾脏的保护作用,对肾脏结缔组织生长因子(CTGF)及Ⅳ型胶原(Col-Ⅳ)的影响。方法:腹腔注射链脲佐菌素(STZ)建立小鼠DN模型,模型成功后随机分为6组:正常对照组、DN模型组、厄贝沙坦组、肾安高剂量组、肾安中剂量组、肾安低剂量组,药物干预4周后,检测相对肾重、血糖、24h尿蛋白量、血肌酐等,免疫组织化法检查肾皮质CTGF和Col-Ⅳ的表达。结果:DN小鼠相对肾重、血糖、24h尿白蛋量、血肌酐、肾皮质CTGF和Col-Ⅳ表达等显著升高,肾安提取液可降低肾皮质CTGF和Col-Ⅳ的表达,改善DN小鼠蛋白尿、肾功能等。结论:肾安提取液能保护DN小鼠肾脏,其机制可能与降低肾皮质CTGF和Col-Ⅳ的表达有关。
