ABSTRACT
Objective: To observe the clinical efficacy of Jinlida (JLD) granules and Tongxinluo (TXL) capsules on type 2 diabetic kidney disease (DKD) under the guidance of vessel collateral theory. Method: A total of 120 patients with type 2 DKD, were randomly divided into 2 groups:the normal control group (60 cases) and the treatment group (60 cases). The patients in normal control group were treated with dietary control and hyperglycemia control. Based on treatment in control group, patients in treatment group were additionally treated with JLD granules (1 bag, tid), and TXL capsules (4 capsules, tid). The treatment was lasted for 12 weeks. The clinical efficacy, traditional Chinese medicine(TCM) syndrome scores were observed and compared before and after treatment. At the same time, the levels of glucose metabolism indexes including fasting blood glucose (FBG),postprandial 2 h plasma glucose (2 hPG), glycosylated hemoglobin (HbA1c) and the insulin resistance (IR); the levels of lipid metabolism indexes including total cholesterol(TC),triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) and the high-density lipoprotein cholesterol (HDL-C); the levels of renal function indexes including urinary albumin excretion rate (UAER) and serum creatinine (SCr); as well as nailfold microcirculation were detected and compared. Result: ①The total effective rate was 80.0% in treatment group, significantly higher than 61.67% in the normal control group (PPPPPβ2-MG in treatment group was significantly obvious than that in the control group (PPConclusion: Tongxinluo combined with Jinlida can improve the clinical symptoms of patients with type 2 diabetic nephropathy and reduce urinary trace albumin, and its mechanism may be related to lowering glucose, regulating lipid metabolism and improving microcirculation.
ABSTRACT
Objective To investigate effect of sitagliptin ( SIT) on the expression of inducible nitric oxide synthase ( iNOS) and nitric oxide ( NO) in type 2 diabetic nephropathy.Methods 30 rats were randomly divided into normal group (NC group), diabetic nephropathy group (DN group) and sitagliptin treatment group (SIT group).The type 2 diabetes mellitus (T2DM) rats were induced by a high fat diet (HFD) plus repeated low dose streptozocin (STZ) injections.At the end of the 12th week in treatment,there were 6 rats in each group, the NO level was determined by Griess method.mRNA levels of iNOS RT-PCR was detect ed by.The expression of iNOS protein was detected by western blot and immunohistochemical method. ResuIts Compared with the NC group, the expression of iNOS and NO of DN group increased significantly.However, compared with DN group, the expression of iNOS and NO of SIT group decreased significantly.ConcIusion SIT can decrease the expression of iNOS and NO, which implies SIT may protect the type 2 diabetic kidney.
