ABSTRACT
Objective To analyze the overactive bladder symptom score (OABSS) in evaluating bladder dysfunction in the different stages among type 2 diabetes mellitus patients,and to explore the value of bladder hyperactivity symptom score in screening early diabetic bladder dysfunction.Methods A total of 1 157 patients with type 2 diabetes mellitus,aged 40-88 yearswith mean age of 60.2 years,were enrolled from October 2013 to October 2016.The survey included the patients' characteristics,past history,current history,OABSS and quality of life (QOL) index scores.T test,single factor analysis of variance and multiple regression analysis are used to analyze the results.Results As many as 1 157 were qualified for final statistical analysis.OABSS is 1.94 ± 1.23 in group with diabetes duration ＜ 10 years,3.24 ± 1.45in group with diabetes duration 10-20 years,and 4.00 ± 1.72 in group with diabetes duration ＞ 20 years.The differences of OABSS in the different duration of diabetes was statistically significant.As diabetic duration increased,OABSS value increased (F =48.419,P ＜ 0.001).The difference of OABSS in the different HbA1c level,age and concurrent peripheral neuropathy was statistically significant.There was no significant difference of OABSS in the different BMI and distinct therapies.There was no significant difference of OABSS in diabetes with hypertension and without hypertension,with cardiopathy and without cardiopathy,with cerebrovascular disease (CVD) and without CVD,with hyperhpemia and without hyperlipemia.The significant factors were used to make multivariate analysis.The results showed that the duration of diabetes,HbA1 c level,age,peripheral neuropathy were still statistically significant.Standardized partial regression coefficient of diabetic duration was 0.366.OABSS was positively correlated with QOL score (r =0.434,P ＜ 0.001).Conclusions The related symptoms in OABSS with diabetic bladder dysfunction is correlated with the duration of diabetes,HbA1c level,age,concurrent peripheral neuropathy among type 2 diabetes.The duration of diabetes was the most significant factor.OABSS is likely to be one of the tools to assess the early symptoms of diabetic bladder dysfunction.

ABSTRACT
Type 2 diabetic rats were treated with recombiriant adenovirus expressing human adiponectin (Ad-APN).The results showed that the levels of both plasma C-reactive protein and soluble intercellular adhesion molecule-1 were significantly decreased in Ad-APN-treated diabetic rats compared with those of diabetic rats [(18.73±4.66 vs 23.60±4.25)mg/L and (14.91±1.79 vs 19.09±2.95) ng/ml,both P＜0.01].These results suggest that increased serum concentration of adiponectin may improve the status of inflammation in diabetes mellitus.
ABSTRACT
Objective To evaluate the effects of exogenous adenovirus-mediated gene transfer of human apM1 gene (Ad-apM1) on malonaldehyde (MAD) and superoxide dismutase (SOD) levels in human umbilical vein endothelial cells (HUVEC). Methods HUVEC proliferation was measured by MTT after infection by AdapM1. Adiponetin protein level in cell culture medium of HUVEC cells infected with Ad-apM1 was detected by double antibody sandwich ELISA. The levels of MAD and SOD were measured by chromatometry. Results MTT assay showed that Ad-apMl had no effect on HUVEC proliferation. Human adiponectin protein levels in cell culture medium significantly increased after HUVEC was infected with Ad-apM1 for 24, 48, and 72 h, along with decreased MAD and increased SOD ( all P<0.05 ). MAD levels markedly increased and SOD levels decreased after HUVEC were incubated with 100 μmol/L H2O2 for 6, 12, and 24 h, and these reactions were reversed by AdapM1 transfection (all P<0.05 ). Conclusions HUVEC infected with Ad-apM1 effectively secrete human adiponectin. Ad-apM1 exerts antioxidation effect and antagonizes H2O2 -induced endothelial injury.
ABSTRACT
Objective:To construct a mutant of human proinsulin with signal peptide code,so that it may be expressed in eukaryotic system to produce mature human insulin in COS-7 cells.Methods:Human proinsulin gene was mutated by the polymerase chain reaction (PCR) for the site-directed mutagenesis method.Two furin recognized sites of Arg-X-Lys-Arg-motifs were introduced into human proinsulin.Signal peptide,Kozak sequence and restriction enzyme cutting site were added and cloned into pcDNA3.1(+) vector and verified by sequencing analysis.Eukaryotic expression vector was constructed and transfected into COS-7 cells.Insulin were evaluated respectively with RT-PCR,radioimmunoassay and Western blot analysis.Results:The sequencing analysis showed that the mutation sites were correct,and the mutant of human proinsulin was constructed successfully.Human insulin mRNA was highly expressed in transfected COS-7 cells,and secretive recombinant human insulin was detected in the culture supernatant of transfected COS-7 cells by Western blotting.Conclusion:A mutant human proinsulin eukaryotic expression vector is obtained and secretive recombinant human insulin is successfully expressed in COS-7 cells.
ABSTRACT
Objective To study the effect of phosphodiesterase inhibitor pentoxifylline (PTX) on type 1 diabetes in NOD mice and its possible mechanism.Methods Blood glucose, urinary glucose, insulitis and incidence of diabetes were investigated in NOD mice treated with PTX, insulitis was observed by HE staining and the expressions of IFN ?, TNF ?, IL 10 in pancreas were measured by RT PCR technique. Results The incidence of diabetes in the PTX group was 30.0% which was significantly lower than 67.9% in the control group (P
