To study a method for determination of sulfamethoxazole, sulfadiazine and trimethoprim tablets, a compound tablet of sulfamethoxazole, sulfadiazine and trimethoprim. METHOD: A capillary zone electrophoresis (CZE) method was used to assay three components of this compound preparation. RESULTS: The complete separation of components was achieved with 0.05 molL-1 pH 6.0 running phosphate buffer and a constant voltage of 20 kV (current of 95 μA～105 μA). The retention times of individual components were between three and eight minutes and a good linearity was shown between concentration and peak area in the concentration range over 70 μgml-1～750 μgml-1. When acetanilide was used as internal standard, the relative standard deviation (RSD) of each component determined in a batch was less than 1% (n=9). The recovery of each component was not less than 96.45% with RSD less than 3%. The analytical results obtained from 6 samples of clinical use were inconsistent with those by standard method, however the quantity of each sulfa drug was obtained by CZE method. CONCLUSION: The results showed this method is accurate, simple, and rapid. When this method is used, the quantity of each three components is determined, but by the standard method, only the total quantity of the two sulfa drugs is obtained.

Objective To explore the effect of triperygium wilfordii polyglucoside(TWP) on the podocytes of rats with diabetes nephropathy(DN). Methods One hundred SD rats were randomly divided into normal control group (Group A),DN group (Group B),TWP group(Group C).TWP group was divided into 3 subgroups(Ca,Cb,Cc)according to the different doses 4,8,16mg·kg-1·d-1,respectively.Rats in DN group and TWp group were given streptozocin(STZ)by intraperitoneal injection to establish animal model of diabetes.After 12 weeks,24 h urinary protein excretion rate(UAER),BUN,Scr,white blood cell(WBC),blood glucose(Glu),and kidney weight (KW)/body weight(BW)were determined.The renal pathological changes were evaluated by HE staining.The structural change of podocytes was observed by transmission electron microscope.The expressions of nephrin and podocin were evaluated by immunofluorescence staining. Results (1)Compared to group A,Scr,BUN,Glu,KW/BW,and UAER were significantly higher(P＜0.05)in group B and group C.Whereas the elevated liver enzymes and the decreased WBC were presented in group Cc (3/20). Compared to group A, the protein expressions of nephrin and podocin in nephridial tissue were lower, and the significant differences of pathomorphology in glomerulus,tubules and podocytes were observed in group B and group C. (2) Compared to group B, KW/BW and UAER were lower in group C (P＜0.01); the protein expressions of nephrin and podocin were higher in nephridial tissue; the pathomorphological improvements were exhibited in glomerulus,tubules and podocytes in group C, paralleled with the increase of TWP dose (P＜0.05 or P＜0.01).Conclusions TWP may exert the protective effect on podocytes in diabetic nephropathy rats,dependent on the dose of TWP. The mechanism may be associated with the up-regulatied expressions of nephrin and podocin.

BACKGROUND:Previous studies have found that miR-21 expression is increased during osteogenic differentiation of bone marrow mesenchymal stem cells, but the action and molecular mechanism of miR-21 are stil unclear. OBJECTIVE:To verify the target gene of miR-21, Spry1, and to explore the role of Spry1 in osteogenic differentiation of human bone marrow mesenchymal stem cells. METHODS:Luciferase report was used to verify Spry1 gene targeted by miR-21, and western blot assay was used to detect the expression of Spry1 in the osteogenesis of human bone marrow mesenchymal stem cells. Spry1 expression vector was established and transfected into human bone marrow mesenchymal stem cells. Osteogenesis ability of human bone marrow mesenchymal stem cells was analyzed after Spry1 high expression by alkaline phosphatase, alizarin red staining, RT-PCR and western blot. RESULTS AND CONCLUSION:Luciferase report suggested that Spry1 was a target gene of miR-21. The expression level of Spry1 was decreased in the osteogenesis of human bone marrow mesenchymal stem cells. Increasing expression of Spry1 could inhibit osteogenic differentiation of human bone marrow mesenchymal stem cells. These results indicate that Spry1 as a target gene of miR-21 negatively regulates osteogenic differentiation of human bone marrow mesenchymal stem cells, and plays an important role in bone formation process.
