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 investigate the relationship between gestational hyperglycemia and adverse pregnancy outcomes and find out the optimum diagnostic criteria of gestational diabetes mellitus in China. Methods A retrospective population-based study of 14 593 pregnant women, who delivered between Jan. 2005 and Dec. 2009 and accepted the gestational diabetes mellitus ( GDM ) screening and diagnosis was performed. The prevalence of gestational hyperglycemia according to different criteria was calculated, and the incidence of adverse pregnant outcomes relation to gestational hyperglycemia according to different criteria was analyzed. Results ( 1 ) According to National Diabetes Data Group (NDDG) criteria and International Association of Diabetes and Pregnancy Study Groups (IADPSG) criteria, the prevalence of gestational hyperglycemia that intervention required was 8.9% (1293/14 593 ) and 14.7% (2138/14 593 )respectively; the prevalence of gestational hyperglycemia differed significantly between NDDG and IADPSG criteria ( P ＜ 0. 05 ). ( 2 ) The prevalence of macrosomia, large for gestational ages ( LGA), cesarean section,preterm birth and neonatal hypoglycemia etc would increase in gestational glucose metabolic disorders according to any criteria. The prevalence of the complications in gestational hyperglycemia according to NDDG criteria, IADPSG criteria and the patients with normal glucose metabolism is as follows, macrosomia:8.4% ( 108/1293), 11.3% (241/2138) and 6. 7% ( 835/12 403 ); LGA: 9. 7% ( 125/1293 ), 11.7% (250/2138) and 5.5% (687/12 403); cesarean section: 59. 0% (763/1293), 60. 4% ( 1291/2138 ) and 51.6%(6397/12403); preterm birth: 11.4% (147/1293), 9.5% (203/2138) and 6.3% (777/12 403); neonatal hypoglycemia: 2. 6% ( 33/1293 ), 2. 2% (46/2138) and 0. 7% ( 89/12 403 ). ( 3 )About 71.3% (922/1293) of the gestational hyperglycemia according to NDDG criteria could be well control only by diet control. Conclusion The prevalence of perinatal complications would increase in gestational hyperglycemia that achieved IADPSG criteria without intervention, so IADPSG criteria is reasonable in China.

ObjectiveTo study whether the current Institute of Medicine (IOM) pregnancy weight gain recommendationsvarybypre-pregnancybodymassindex(BMI)wassuitabletoChinese people.MethodsA study was conducted on 4736 term singleton live birth gravidas,who were diagnosed normal glucose metabolism and delivered in Peking University First Hospital in 2005 and 2009,by reviewing the medical records.Based on the pre-pregnant BMI,the selected cases were divided into 3 groups:low body mass group ( BMI ＜ 18.5 kg/m2,n =465 ),normal body mass group ( BMI 18.5 - 24.9 kg/m2,n =3549),over body mass group ( BMI ≥ 25 kg/m2,n =722).All the cases were divided into 3 subgroups based on pregnancy weight gain as below,within,and above the IOM recommendations in each pre-pregnant BMI group.Totally 4736 newborns were divided by birth weight into 3 groups:normal birth weight group ( weight 2500 - 4000 g,n =4339 ),macrosomia group ( weight ≥ 4000 g,n =359 ) and low birth weight group (weight ＜ 2500 g,n =38).The difference of age,gestational age,pre-pregnant weight,pre-pregnant BMI and history of delivery of cases between 2005 and 2009 were analyzed.The difference of pregnancy outcome of women whose gestational weight gain was below,within,and above the IOM recommendations was analyzed.Results (1) Compared to mothers with pregnancy weight gain within IOM recommendations in low body mass group,risk of low birth weight in offspring was elevated tendency with pregnancy weight gain below IOM recommendations ( OR =3.71,95％ CI:0.97 - 14.12,P =0.055 ).(2) In normal body mass group, compared to women with pregnancy weight gain within IOM recommendations, risk of macrosomia in offspring was elevated with pregnancy weight gain above IOM recommendations ( OR =2.14,95％ CI:1.62 - 2.83,P ＜ 0.01 ).( 3 ) In over body mass group,compared to women with pregnancy weight gain within IOM recommendations,risk of macrosomia in offspring was elevated ( OR =3.25,95％ CI:1.65 -6.39,P =0.001 ) and risk of hypertensive disorders complicating pregnancy was high ( OR =1.79,95％ CI:1.04 -3.09,P =0.037 ) in women with pregnancy weight gain above IOM recommendations.ConclusionThe current IOM pregnancy weight gain recommendations vary by pre-pregnancy BMI may be suitable to Chinese people.

Objective To observe the changes of serum bilirubin(BIL) and high-sensitivity C-reactive protein(hs-CRP) after percutaneous coronary intervention(PCI) in acute myocardial infarction(AMI) patients.Methods The TBiI,IBil,DBil and hs-CRP levels in serum were detected in 60 AMI patients within 6 hours after attack with immunoturbidimetry before PCI,at the point of operation,6h,12h,24h,72h and 7d afer PCI.30 healthy persons were chosen as normal control.The two groups were compared.Results The hs-CRP level was increased gradually with time in AMI patients after PCI.The peak value was at 72h after PCI and it was significantly higher than those in the normal group( P ＜ 0.05 ).The TBil,IBil,DBil levels at pre-PCI point were significantly lower than the normal group (P ＜ 0.05).These index were gradually recovered to the normal group and no significancet differences between them (P ＞ 0.05 ).The coefficient correlation of hs-CRP and TBil,IBil,DBil were 0.44 ( P ＞ 0.05 ).Conclusion The TBil,IBil,DBil and hs-CRP levels in short time after attack of AMI with PCI presented a dynamic changing and recovered to the normal level.No associativity was observed between them,but as the follow-up index,it was significant for the disease turnover.

Objective To investigate the relationship between early pregnancy fasting plasma glucose (FPG) and gestational glucose metabolism disorders. Methods Six hundred and fifty-six pregnant women who were singleton, non-diabetes before pregnancy and had FPG examined during 5-13 weeks of pregnancy were admitted into this study from January 1, 2009 to May 31, 2009. All these subjects had routine prenatal examination and finally delivered in the Department of Obstetrics of Peking University First Hospital. The FPG, 50 g glucose challenge test (GCT) after 24 weeks of pregnancy, 75 g oral glucose tolerance test (OGTT), gestational diabetes mellitus (GDM),gestational impaired glucose tolerance (GIGT) were analyzed with receiver operating characteristic (ROC) curve. Results (1) Relationship between FPG and GCT were analyzed with ROC curve.The maximum area under curve was 0. 539 (95% CI: 0. 493-0. 586) and there was no correlation between the FPG and GCT results(P=0. 057). (2) Relationship between early pregnancy FPG and abnormal FPG examined after 24 gestational weeks were also analyzed . The maximum area under curve was 0. 796(95% CI: 0. 672-0. 920). If 5. 05 mmol/L was taken as the cutoff value, the sensitivity and specificity was 54. 5% and 83. 2%, respectively. There was significant relationship between the two values (r=0. 432, P=0. 000). (3) There were no relationship between early pregnancy FPG and the blood glucose value of 1, 2 and 3 h in 75 g OGTT (r=0. 093, 0. 036 and 0. 107, P=0.122, 0. 549 and 0. 074 respectively). OGTT 0 h value was positively related to OGTT 1, 2 and3 h glucose level (r=0.493, 0.421 and 0.368, P=0.000, respectively). (4) All early pregnant FPG values in this study were under 6.1 mmol/L. Twenty-two GDM and 27 GIGT patients were diagnosed in this study. Early pregnancy FPG did not relate to the GDM and GIGT diagnosis.Conclusions Early pregnancy FPG could not replace 50 g GCT as an early screening for glucose metabolic abnormality in pregnancy, but FPG during early pregnancy is necessary.

Objective To evaluate the role of spinal cord CABAA receptors in the analgesic effect of propofol on visceral pain in rats. Methods Adult female SD rats, weighing 190-240 g, were used in this study.The animals were anesthetized with intraperitoneal ketamine 50-100 mg/kg. Intrathecal (IT) catheters were placed at L5-6 interspace according to the technique described by Storkson et al. Thirty-two animals in which IT catheters were successfully placed were randomly divided into 4 groups ( n = 8 each) : dimethyl sulphoxide (DMSO) group (group D), propofol group (group P), bicuculline group (group B) and bicuculline + propofol group (group B +P). Visceral pain was induced by injecting 10% formalin 100 μl underneath the mucous membrane of rectum.Groups D, P and B received IT DMSO 5 μl, propofol 10 μg and bicuculline 2 μg respectively. Group BP received IT bicuculline 2 μg and then IT propofol 10 μg 10 min later. The L5-S1 segment of the spinal cord was removed 2 h after formalin injection to determine FOS protein expression by hnmuno-histochemistry. Results Compared with groups D and B, FOS protein expression was significantly down-regulated in group P ( P ＜ 0.05 ) . There was no significant difference in FOS protein expression between groups D and B ( P ＞ 0.05) . FOS protein expression was significantly up-regulated in group BP compared with group P ( P ＜ 0.05) . Conclusion Propofol has analgesic effect on visceral pain in rats through spinal cord GABAA receptor action.

Objective To investigate the appropriate range of gestational weight gain in pregnant women with abnormal glucose metabolism.Methods A retrospective study was conducted on 661 term singleton pregnant women with gestational abnormal glucose metabolism,who delivered in the Department of Obstetrics and Gynecology of Peking University First Hospital from Jan.2005 to Dec.2007,by reviewing the medical records.All sujects were divided into 4 groups according to their body mass index (BMI) before pregnancy:group Ⅰ (n=40):BMI<18.5;group Ⅱ (n=400):BMI18.5-23.9;group Ⅲ (n=162):BMI 24.0-27.9;group Ⅳ (n=59):BMI≥28.0.The weight gain among different groups and that between women who delivered normal birth weight infant and maerosomia were analyzed.The weight gain of pregnant women who delivered babies weighing 3000～3500 g in each group was determined as the appropriate weight gain for that group.Results The same results were achieved that the weight gain in pregnant women who delivered macrosomia was significantly higher than those who delivered normal birth weight newborns in each group,ie,the weight gains for women who had macrosomia and normal birth weight infants were (17.0±5.2) kg and (14.1±4.7) kg in group Ⅱ,(16.8±7.3) kg and (11.9±5.1) kg in group Ⅲ and (18.3±6.7) kg and (11.2±5.4) kg in group Ⅳ,respectively (P<0.05).The appropriate ranges of weight gain for each group were (15.6±3.3) kg,(14.0-18.0) kg for group Ⅰ,(13.9±4.6) kg,(11.0-16.5) kg for group ]],(11.5±5.2)kg,(9.0-15.0) kgforgroup Ⅲ,(10.1±2.9) kg,(7.0-12.7) kg forgroup Ⅳ.Conclusions Appropriate weight gain based on prepregnant BMI,together with glucose monitoring in women with gestational abnormal glucose metabolism,is helpful for fetal weight control.
