Objective To observe the effects of propylene glycol mannate sulfate(PGMS) on the expression of ICAM-1 and VCAM-1 in kidney of diabetic rats, and explore the protective effect of PGMS on kidney. Methods Diabetes was induced by injecting STZ. Then the rats were randomly divided into four groups: normal control group, diabetic modal group, treatment group with high-dose and low-dose of PGMS. 8 weeks later, the blood glucose concentrations, HbA1c, the ratio of kidney weight to body weight, urinary albumin excretion rate (UAE ) in 24 hours were examined. The ICAM-1 and VCAM-1 located were detected by immunohistochemistry, while the expression of ICAM-1 and VCAM-1 were detected by Western blot method and the levels of ICAM-1 and VCAM-1 mRNA by RT-PCR.Results PGMS could reduce kidney hypertrophy and lower urinary albumin excretion rate (UAE)of 24-hour significantly. Immunohistochemical study with light microscopy demonstrated that the levels, both ICAM-1 and VCAM-1 in the kidney of test groups decreased obviously. PGMS down-regulated the mRNA and protein levels of ICAM-1 and VCAM-1 significantly . A positive correlation between expression of ICAM-1,VCAM-1 and kidney lesion was observed. Conclusion: PGMS decreased the expression of ICAM-1 and VCAM-1 in diabetic rats.

Objective To investigate the effect of total glucosides of paeong (TGP) on the liver lipid infiltration and fibrosis in rats with non-alcoholic fatty liver disease (NAFLD) induced by fructose and high-fat diet. Methods Fructose-high-fatty induced NAFLD rat model was established. Metformin ( MET,200 mg · kg-1 ) and TGP (200,100 mg · kg-1 ) was intragastrically given to the rats in the treatment group,TGP high dose and low dose group,respectively. Normal control group and model control group was intragastrically treated with equivalent distilled water (10 mL·kg-1 ). At the fourth week after the treatment,all the rats were sacrificed and the indices such as serum fasting blood glucose(FBG),INS,insulin sensitivity index (ISI),triglycerides(TG),apelin-36,visfatin,alanine aminotransferase(ALT),aspartate aminotransferase(AST),free fatty acid (FFA),collagen Ⅲ(COLⅢ),collagen Ⅳ(COLⅣ) were determined. Hepatic content of TG was determined and the pathological changes in the liver tissues were observed under the microscope. Results As compared with the model control group,TGP effectively decreased FBG,INS,TG in serum and liver tissues,activity of ALT and AST in serum and content of FAA,Apelin, Visfatin,COLⅢ and COLⅣ,with significant differences (P<0. 05 or P<0. 01). TGP alleviated lipid infiltration and fibrosis in rat liver tissues. Conclusion TGP can inhibit effectively lipid infiltration and fibrosis of NAFLD rats,probably through improving glucolipid metabolism and antogonizing insulin resistance.
