Objective To explore the clinical efficacy of captopril combined with nifedipine in the treatment of type 2 diabetes mellitus complicated with hypertension.Methods 100 patients with type 2 diabetes mellitus complicated with hypertension were divided into two groups by randomized single blind method.The two groups were given conventional hypoglycemic therapy,50 cases in the control group were treated with captopril,while 50 cases in observation group received captopril combined with nifedipine sustained -release tablets.The clinical therapeutic effect was compared between the two groups.Results The effective rate of the observation group was 94%,which of the control group was 80%,the difference was statistically significant (χ2 =9.65,P<0.05).After treatment,the diastolic blood pressure[(80.45 ±3.65)mmHg],systolic blood pressure[(128.67 ±5.66)mmHg],fasting blood glucose[(6.65 ±0.37)μmol/L],2h postprandial blood glucose[(9.76 ±1.22)μmol/L]of the observation group were significantly reduced than before treatment (t =8.06,8.18,8.00,7.94,all P <0.05),and diastolic blood pressure and systolic blood pressure were significantly different with the control group(t=8.66,7.90,all P<0.05). After treatment,the serum creatinine (97.44 ±6.32)μmol/L,urea nitrogen (4.20 ±0.30) mmol/L and 24h urinary albumin (17.99 ±4.10) mg/L of the observation group were significantly reduced compared with before treatment (t=7.67,8.27,8.32,all P<0.05),and the indicators had significant differences with the control group(t=7.23, 7.65,7.67,all P<0.05).Conclusion Captopril and nifedipine sustained-release tablets in the treatment of type 2 diabetic patients with hypertension can effectively reduce the blood pressure,improve renal function,and it has good clinical application and promotion value.

Objective To explore the effects of high insulin and high glucose concentrations on glucose transport activity,the expression of insulin signaling peptides and glucose transporter 4(GLUT4) translocation in primary cultured rat adipocytes.Methods Isolated rat adipocytes were cultured for 24h at insulin(10 4?U/ml) and different concentration glucose(5,10,15 and 25mmol).Then the glucose uptake,cellular contents of insulin receptor substrate(IRS) 1/2,phosphatidylinositol 3-kinase 85 subunit(p85),protein kinase B(PKB) and GLUT4 were measured by Western blotting method.Results These adipocytes treated with insulin and different high concentration glucose had shown to impair glucose uptake in a dose-dependent manner,inhibited cellular IRS1 expression,impaired IRS2 protein expression independent on glucose concentration in the medium,it did not influence the contents of p85,PKB and GLUT4,but decreased GLUT4 translocation.Conclusions Chronic high insulin induced insulin resistance may be caused by the increasing glucose concentration surrounding the cells.The mechanism may be involved in affecting IRSs protein expression and GLUT4 translocation.

Objective To explore the effects of high glucose on glucose transport activity, and phosphorylationandexpressionofinsulinsignalingproteins in primary cultured rat adipocytes. Methods Isolated rat adipocytes were cultured at different glucose concentrations (5, 10, 15, 25 mmol/L) for 24 h. Then the glucose uptake, the phosphorylations of insulin receptor (IR), insulin receptor substrate (IRS) 1 and 2 and protein kinase B (PKB) as well as the protein expressions of IRS1, IRS2, p85 subunit of phosphatitylinositol 3 kinase (p85) and PKB were measured. Results These adipocytes treated with different high glucose showed the impairment of the basal and insulin induced increase in glucose uptake and significant decrease of IR, IRS1 and PKB phosphorylations as well as IRS1 protein expression, but up regulation of IRS2 protein expression. p85 and PKB contents and IRS2 phosphorylation were unaffected. Conclusion The exposure to high glucose inhibits glucose uptake and induces insulin resistance in adipocyte. The mechanism may be involved in affecting the multiple step phosphorylations and the expressions of insulin signaling proteins.

Objective To assesment the effect of risk factors at gestational diabetes mellitus (GDM).Methods We collected 427 pregnant women who had done 75 g oral glucose tolerance test (OGTT) between September 1st,2012 and April 19th,2013 in Peking University First Hospital,including 74 pregnant women diagnosed as GDM (GDM group) and 353 pregnant women undiagnosed (non-GDM group).Then we conducted a multiple logistic regression to analyze the clinical datas collected from two groups,which included age,pre-pregnancy body weight and body mass index (BMI),body weight during 11-12 weeks pregnancy,body weight during 23-24 weeks pregnancy; and fasting plasma glucose(FPG),triglyceride (TG),total cholesterol (TCH),high density lipoprotein (H DL),low density lipoprotein (LDL),fasting insulin (FINS),homeostasis model assessment of insulin resistance (HOMA-IR) during early pregnancy; and family history of diabetes mellitus.Results (1)There were significant difference in age,pre-pregnancy BMI,and FPG,TG,FINS,HOMA-IR during early pregnancy,and family history of diabetes mellitus between two groups (P ＜ 0.05).(2) The risk factors of GDM that have statistical significance included FPG during early pregnancy (OR:4.03,95 ％ CI:1.62-10.02),family history of diabetes mellitus (OR:3.15,95 ％ CI:1.66-5.99),TG during early pregnancy (OR:2.13,95 ％ CI:1.17-3.87),BMI before pregnancy (OR:1.36,95 ％ CI:1.08-1.70),age ≥ 35 years (OR:1.15,95 ％ CI:1.05-1.26),early pregnancy weight gain (OR:1.20,95％ CI:1.06-1.35),mid pregnancy weight gain (OR:1.28,95％ CI:1.12-1.47),FINS during early pregancy (OR:1.09,95％ CI:1.01-1.17).Conclusions FPG,TG and FINS during early pregnancy,BMI before pregnancy,early and mid pregnancy weight gain,family history of diabetes mellitus and age≥35 years are the indepadent risk factors for GDM.We should pay more attention to FPG and TG during early pregnancy,and put weight management into practise since early pregnancy and try to control pregnancy weight gain within reasonable limits.

BACKGROUND : Chitosan, derived from chitin, has a poor solubility which limits its application greatly. For improving its dissolubility, according to the feature that intramolecular hydroxy and amino group in chitosan are easy to be chemically modified, and functional groups are introduced to improve its solubility and functionality to widen the range of its application, which has become one of the new trend of development for investigating the application of chitosan. OBJECTIVE: To sum up the research advancements in the application and modification of chitosan in carboxylation,acylation, alkylation, etherification, etc.RETRTEVE STRATEGY: The relevant articles published in English between 1998 and 2007 were searched for in Pubmed database with the key words of "chitosan, modification", and the relevant articles published between 1998 and 2007 were searched for in Elsevier Science database with the key words "chitosan, modification" and search "derivate" within search results in English. Articles closely related to the structural modification and application of chitosan were involved, and repetitive and old studies were excluded.LTTERATURE EVALUATION: Totally 154 articles were selected, and 30 of them are accorded with the inclusive criteria,including 5 are reviews, and the others are clinical or experimental studies.DATA SYNTHESTS: The intramolecular hydroxy and amino groups in chitosan are mostly modified because they are easy to be chemically modified. Recently, reports lay particular emphasis on the modification in carboxylation, acylation,alkylation, etherification, etc. Functional groups are introduced to improve its solubility and functionality to widen the range of its application.CONCLUSTON: The water-solubility of chitosan can be improved through structural modification and introducing multifunctional group, which can also bring about much more special efficacies.
