摘　　要：OBJECTIVE:To investigate the dynamic changes of urinary nephrin,and the relationship between it and urinary albumin excretion rate(UAER) in a diabetic rat model,as well the effects of yiqiyangyinhuayutongluo recipe.METHODS:Diabetic model was induced by high fat diet combined with low-dose Streptozotocin(STZ) in rats.Normal group(NG),model group(MG),and yiqiyangyinhuayutongluo recipe treated group(YHTG) were set.Gastrointestinal Yiqiyangyinhuayutongluo recipe was administered once daily for 32 w.At the end of the 2nd w(2w),8w,16w,and 32w,fasting blood glucose(FBG),UAER and 24h urinary nephrin(U-nephrin) were detected.RESULTS:Compared with NG,FBG in MG increased notably(P<0.05).Compared with MG,FBG of YHTG reduced slowly,and the difference was significant(P<0.05) since 16w.U-nephrin and UAER in MG increased significantly from 2w,peaked at 16w,lessened in different degree at 32w,but were still higher than NG.The correlation analysis showed that there was a significant positive correlation between U-nephrin and UAER at different time,the correlation coefficient as r>0.9,and P<0.05.Compared with MG,U-nephrin and UAER in YHTG decreased markedly(P<0.05) except for U-nephrin at 8w.CONCLUSIONS:U-nephrin and UAER in diabetic rat model have a positive linear correlation.Yiqiyangyinhuayutongluo recipe can reduce UAER markedly,and preventing the lose of nephrin in urine maybe one of the mechanisms.OBJECTIVE：To investigate the dynamic changes of urinary nephrin,and the relationship between it and urinary albumin excretion rate（UAER） in a diabetic rat model,as well the effects of yiqiyangyinhuayutongluo recipe.METHODS：Diabetic model was induced by high fat diet combined with low-dose Streptozotocin（STZ） in rats.Normal group（NG）,model group（MG）,and yiqiyangyinhuayutongluo recipe treated group（YHTG） were set.Gastrointestinal Yiqiyangyinhuayutongluo recipe was administered once daily for 32 w.At the end of the 2nd w（2w）,8w,16w,and 32w,fasting blood glucose（FBG）,UAER and 24h urinary nephrin（U-nephrin） were detected.RESULTS：Compared with NG,FBG in MG increased notably（P〈0.05）.Compared with MG,FBG of YHTG reduced slowly,and the difference was significant（P〈0.05） since 16w.U-nephrin and UAER in MG increased significantly from 2w,peaked at 16w,lessened in different degree at 32w,but were still higher than NG.The correlation analysis showed that there was a significant positive correlation between U-nephrin and UAER at different time,the correlation coefficient as r〉0.9,and P〈0.05.Compared with MG,U-nephrin and UAER in YHTG decreased markedly（P〈0.05） except for U-nephrin at 8w.CONCLUSIONS：U-nephrin and UAER in diabetic rat model have a positive linear correlation.Yiqiyangyinhuayutongluo recipe can reduce UAER markedly,and preventing the lose of nephrin in urine maybe one of the mechanisms.
