Aim To observe the changes on the expression of ?-SMA in rats with adriamycin-induced nephrothy and intervention of Valsartan. Methods The model group were made by unilateral nephrectomy with twice-adriamycin injections by caudal vein. Immunohistochemical method, flow cytometry and pathologic image analysis were used to observe the expression of ?-SMA, FN and LN in rats. Results The expression of ?-SMA was positive in the model group. Rates of positive cell and protein semi-quantitative analysis were more higher than the sham group(P

Objective To evaluate the effect of Ji Tang Zhi on glucose metabolism in insulin resistance (IR) HepG 2 cell line,and to explore the related mechanism.Methods The HepG2 cells were incubated in culture medium addition of 10-7 mol/L insulin for 24 h to establish the IR cell model.Effect of Ji Tang Zhi on rate of glucose absorption in HepG2 cell was detected by the method of glucose oxidase-peroxidase (GOD-POD).We performed an MTT assay to determine cytotoxicity effects of Ji Tang Zhi on HepG2 cell line.The expression of p-IRS-1 Ser307,PI3K and GLUT-4 were detected by Western blotting.Results Incubated with 10-7 mol/L insulin for 24 h,the insulin resistance cell model had been built.Compared with model group,the rate of glucose absorption of cell treated with JTZ (30 ～ 120 μg/mL) was significantly improved.According to model cells,the expression of GLUT-4 and PI3K decreased significantly compared to control cells.While the expression of p-IRS-1 Ser 307 was inhibited and GLUT-4 and PI3K expression were increased in IR cells after treated with JTZ (30 ～ 120 μtg/mL).Conclusion JTZ exert beneficial effects on hyperglycosemia in IR cell line possibly through regulating the levels of GLUT-4,p-IRS-1 Ser307 and PI3K in HepG2 cell.

Objective To compare the efficacy of MRI-transrectal ultrasound(TRUS)software fusion-guided biopsy and cognitive fusion-guided biopsy for detecting prostate cancer(PC).Methods Data of 120 patients with suspected PC(127 lesions)who underwent transperineal prostate biopsy with 2-3 times of target biopsy(TB)and 10 times of system biopsy were retrospectively analyzed.According to TB guidance methods,73 cases(78 lesions)received MRI-TRUS software fusion-guided biopsy were classified into group A,and 47 cases(49 lesions)received cognitive fusion-guided biopsy were classified into group B.The positive rate of PC,clinic significant PC(csPC)and PC in different sized lesions by TB were compared between groups,and the positive rate of PC between 2 or 3 times TB was also compared within each group.Results The positive rate of PC and csPC detected by TB was 55.13%(43/78)and 39.74%(31/78)in group A,53.06%(26/49)and 34.69%(17/49)in group B,respectively,no significant difference was found(all P＞0.05).The positive rate of PC in lesions with the maximum diameter≤10 mm detected by TB in group A was higher than that in group B(P＜0.05),but no significant difference of lesions with the maximum diameter＞10 mm and＜15 mm nor≥15 mm was found between groups(all P＞0.05).No significant difference of positive rate of PC was found between 2 and 3 times TB in group A(P＞0.05),while positive rate of PC of 3 times TB was significantly higher than that of 2 times TB in group B(P＜0.05).Conclusion MRI-TRUS software fusion-guided biopsy had positive rate of PC and csPC similar to that of cognitive fusion-guided biopsy,but was helpful for reducing times of TB and increasing detecting rate for lesions with the maximum diameter≤10 mm.
