Objective To investigate the relationship between Sfrp5 and T2DM macroangiopathy , and to evaluate the activation of calcium dobesilate. Methods T2DM patients were divided into experimental group (IMT≥0.90 mm,n = 65)and control group (IMT < 0.90 mm, n = 30)and patients in experimental group were randomly further divided into group A (n = 30,treated with calcium dobesilate) and group B (n = 35, treated with routine therapy). Another 20 healthy control were involved as normal group. Sfrp5,IL-10,TC,TG,FPG, HbA1c and IMT were observed before and after treatment. Results Sfrp5 and IL-10 in experimental group and control group were lower than those in normal group (P < 0.01)and Sfrp5 and IL-10 in experimental group were lower than those in control group (P < 0.05). Correlation analysis showed that sfrp5 and IL-10 were negatively correlated with these above-mentioned indicators and Sfrp5 was positively correlated with IL-10(P < 0.05). After 16-week treatment, the contents of FBG, lipid, HbA1c and IMT were decreased in group A and B, but Sfrp5 and IL-10 were increased in group A (P < 0.01). Sfrp5 and IL-10 didn't alter significantly in group B (P >0.05). IMT in group A were decreased when compared with group B (P < 0.05). Conclusion Sfrp5 is negatively correlated with macroangiopathy. Calcium dobesilate can elevate Sfrp5 and IL-10,thus delay the progression of macroangiopathy.

Objective To study the effects of glimepiride and short-term intensive therapy with insulin on plasma glucose and beta-cell function in newly diagnosed type 2 diabetic patients.Methods 80 newly diagnosed type 2 diabetic patients were divided into two groups of 40 patients each and randomly treated with insulin or glimepiride plus metformin for 8 weeks.The FBG,2hPBG,HbA_1c,improvement of beta-cell function were measured before and after intensive therapy in each group.Results After the treatment,FBG,2hPBG,HbA_1c were significantly decreased (all P<0.001) in each group;FCP and 2hPCP were increased(P<0.05)in each group.Conclusion Glimepiride or short-term intensive therapy with insulin plus metformin could effectively improve glycemic control and beta-cell function in newly diagnosed type 2 diabetic patients.

Objective To investigate the role and its mechanisms of tea polyphenols (TP) in the prevention of diabetic renal fibrosis.Methods Mouse model of diabetes mellitus was induced by high-fat diet combined with intraperitoneal injection of streptozotocin (STZ,50 mg/kg).Real-time quantitative polymerase chain reaction (RT-PCR) and Western blotting were used to determine the transcription and expression of genes related to the renal fibrosis.Results Diabetic mouse model was successfully established by injection of high-fat diet plus STZ.The transcription of E-cadherin was decreased and transcriptions of genes related to the renal fibrosis such as transforming growth factor β1 (TGF-β1),vimentin,α-smooth muscle actin (α-SMA),fibronectin,collagen Ⅰ,and collagen Ⅳ were increased in the renal tissues of diabetic mice,which indicated the diabetic nephropathy with renal fibrosis in diabetic mice.Treatment of diabetic mice with TP for 8 weeks could reverse the process of diabetic nephropathy with renal fibrosis in accompanied with the increase of E-cadherin transcription and decrease of TGF-β1-targeted genes such as vimentin,α-SMA,fibronectin,collagen Ⅰ,and collagen Ⅳ in the renal tissues of diabetic mice.Moreover,incubation of normal rat kidney proximal tubular epithelial cell line (NRK-52E) cells with TGF-β1 could also induce the changes in fibrotic morphological and transcription or expression of fibrosis related genes,and all effects of TGF-β1 could be inhibited by TP treatment in NRK-52E cells.Conclusions These results indicate that chronic treatment with TP may relieve renal fibrosis of diabetic nephropathy through the inhibition of TGF-β signaling pathway and provide important experimental data for the prevention and treatment of diabetic nephropathy.

Objective To study the infection status of Helicobacter pylori (H. pylori) and sensitivity to commonly used antibiotics in Taizhou district,Zhejiang province. Methods 39 099 cases aged between 5 and 95 years old(mean as 48.42 years)were involved during January 2010 to December,2013 for this study. Sex ratio was 1 ∶ 0.95. Yearly distribution of the number of cases were 5 031,6 709,11 902 and 15 457 in 2010,2011,2012 and 2013,respectively. Gastric mucosal specimens were collected and H. pylori strains were isolated and cultured in the same platform in Zhiyuan Medical Inspection Institute of Hangzhou. Resistance tests of all the H. pylori isolates were performed to 6 commonly used antibiotics:metronidazole,clarithromycin,amoxicillin,gentamicin, levofloxacin and furazolidone with the agar dilution method. The antibiotic resistance rates of H. pylori strains isolated during year 2010-2013 and the changing trends were analyzed. Results Resistance rates to levofloxacin and clarithromycin kept at higher level and the highest was in 2011 and then decreased in both 2012 and 2013 (P<0.01). The resistance rates to both levofloxacin and clarithromycin reached the highest in 2011(P<0.01),and decreased thereafter,with no significant change in 2013 to 2012(P>0.05). Conclusion Antibiotic resistance rate against metronidazole for HP isolate was highest. Resistance rate against amoxicillin and furazolidone,gentamicin was low. Clinical treatment should choose amoxicillin and furazolidone,gentamicin. The resistance rates to levofloxacin and clarithromycin had been seen at a significantly downwarding trend since 2011. However,the combined resistance rates to levofloxacin and clarithromycin did not seem to reduce since 2012.
