Objective To investigate the effects of Wuling Powder on insulin resistance of C57BL/6J mice induced by high lipid diet, and discuss the mechanism. Methods C57BL/6J mice were randomly divided into six groups:normal group, model group, rosiglitazone group, Wuling Powder in low, middle, and high dose groups, 10 mice per group. Besides the normal group, other five groups were fed with high fat and sugar diet, with a purpose to establish insulin resistance model. Normal group and model group were given pure water. Rosiglitazone group received a gavage with rosiglitazone of 0.75 mg/kg. Wuling Power low, middle, and high groups received gavage with Wuling Power of 1.23, 3.69, 11.07 g/kg, respectively, the does volume was 0.2 mL/10 g, once a day. The weight and abdominal girth were detected every week. At the end of the sixth week, mice were given 12-hour fasting, and their eyeball were taken for blood. The body weight, length, and fat in abdomen and both kidneys were detected. Paraffin section was made with HE staining. FPG and FINS of each group were detected. ISI and IRI were calculated, and TC and TG were detected. Results Compared with the model group, Wuling Powder can significantly reduce the body weight and abdominal girth of mice (P<0.01, P<0.001), improve liver fatty degeneration, lower the FPG, FINS, TCH, TG, IRI, and increase the ISI in mice (P<0.05, P<0.01). Conclusions Wuling Powder has the effect of preventing insulin resistance of C57BL/6J mice induced by high lipid diet.

Objective To determine the inhibitory effect of a synthetic hexa-peptide GGWSHW (G peptide) derived from thrombospondin-1 (TSP1) on TGF-? activation induced by angiotensin Ⅱ (Ang Ⅱ) in cultured human renal tubular epithelial cells. Methods Human proximal tubular epithelial cell line (HK-2) was cultured in vitro, untreated HK-2 cells were acted as normal control group. HK-2 cells were then stimulated by Ang Ⅱ for 1-24 hours (Ang Ⅱ stimulation group),so that optimal dosage and duration could be chosen.One hour prior to induction,HK-2 cells were pretreated with 10 ?mol/L peptide G (G peptide treated group)or losartan (losartan treated group), the blocker of I type receptor of Ang Ⅱ was acted as inhibitory control.The mRNA and protein levels of TSP1,TGF-?1,FN and PAI-1 were measured by RT-PCR and Western blot. Confocal microscopy and flow cytometry were performed to detect the presence of TSP1, TGF-?1 and co-positive expression of two protein, respectively.The concentrations of total and active TGF-?1 as well as FN and PAI-1 in cell culture supematants were measured by ELISA. Additionally, the expression of Smad2 and p-Smad2 was also examined for the bioactivity of TGF-?1 signaling protein. Results Ang Ⅱ enhanced the expression of TSP1 and TGF-?1 in a temporal-spatial dependent manner. The optimal dosage and duration were 1 ?mol/L and 6 hours,for TSP1,and 0.1 ?mol/L and 12 hours for TGF-?1 respectively.Comparing with untreated HK-2,the co-expression of TSP1 and TGF-?1 induced by A Ⅱ showed a increase of 5.4 folds.In addition,the protein level of p-Smad2 was elevated remarkedly, the mRNA level of FN and PAI-1 was up-regulated by 3 and 1.5 folds, and the concentration was increased by 2.0 and 1.9 folds respectively. Peptide G had less effect on the expression of TSP1 and TGF-?1,whereas it significantly reduced the secretion of active TGF-?1,though total level of TGF-?1 remained up-regulated. Furthermore,comparing with losartan treated group, p-Smad2 expression was reduced by 28.9%, the mRNA level of FN and PAI-1 was decreased by 34.5% and 26% respectively,and the protein levels were reduced by 11.0% and 8.9% respectively. Conclusion The inhibitory peptide derived from TSP1 effectively suppresses TGF-?1 activation through a competitive mechanism and also reduces the secretion of FN and PAI-1 associated with fibrosis.
