【摘要】：目的:观察参芪泄浊饮对慢性肾衰大鼠肾组织基质金属蛋白酶9(MMP-9)、基质金属蛋白酶抑制剂1(TIMP-1)基因表达的影响。方法:采用Yokozawa法复制慢性肾衰大鼠模型,随机分为参芪泄浊饮高剂量组、常规剂量组、氯沙坦组、模型组及空白组,高剂量组、常规剂量组、氯沙坦组分别予参芪泄浊饮水煎液20 m L/(kg·d)、参芪泄浊饮10 m L/(kg·d)、氯沙坦9 mg/(kg·d),模型组与空白组大鼠均予纯净水10 m L/(kg·d),连续给药8周,全部大鼠麻醉后腹腔采血,取左肾,ELLISA法测量血肌酐(Scr)、尿素氮(BUN)、丙氨酸转氨酶(ALT)并采用荧光定量PCR检测肾脏MMP-9、TIMP-1 mRNA的表达。结果:1高剂量组Scr水平明显低于常规剂量组、氯沙坦组及模型组;常规剂量组与氯沙坦组无明显差别,且均低于模型组;2高剂量组MMP-9 mRNA表达水平明显高于常规剂量组、氯沙坦组及模型组;常规剂量组与氯沙坦组无明显差别,且均高于模型组;高剂量组TIMP-1 mRNA表达水平明显低于常规剂量组、氯沙坦组及模型组;常规剂量组与氯沙坦组无明显差别,且均低于模型组;3各组ALT水平较空白组比较均无显著差别。结论:参芪泄浊饮可通过调节MMP-9及TIMP-1表达来缓解慢性肾衰肾脏功能的恶化。
[Abstract]:Aim: to observe the effect of Shenqi Xiezhuo decoction (Shenqi Xiezhuo decoction) on the expression of matrix metalloproteinase 9 (MMP-9) and matrix metalloproteinase inhibitor 1 (TIMP 1) in renal tissue of rats with chronic renal failure (CRF).Methods: the rat model of chronic renal failure was established by Yokozawa method. The rats were randomly divided into three groups: high dose group, routine dose group, losartan group, model group and blank group, high dose group and routine dose group.姘�娌欏潶缁勫垎鍒�浜堝弬鑺�娉勬祳楗�姘寸厧娑，
