Objective To compare the differences of clotting laboratory indices and thromboelastogram (TEG) parameters between pregnant women with gestational diabetes mellitus (GDM ) and healthy pregnant women .Methods The detection results of clotting laboratory indices and TEG in 46 pregnant women with GDM and 49 healthy pregnant women in our hospital from June 2013 to July 2014 were retrospectively analyzed and compared .Results In the comparison of the GDM group and the control group ,the traditional clotting laboratory indices ,INR and PT had statistically significant differences(P<0 .05) .However ,other tra‐ditional clotting laboratory indices ,like APTT ,FIB ,PLT showed no statistically significant differences (P>0 .05) .The common TEG indices of R value ,K value ,Angle ,MA value and CI value were statistically different between the GDM group and control group(P<0 .05) .Conclusion TEG is more sensitive than traditional clotting detection in monitoring the prethrombotic state of pregnant women with GDM and has certain significance for guiding early clinical intervention ,alleviating or delaying complications and improving the maternal and infantile outcome .

A metabonomics method based on gas chromatography_mass spectrometry ( GC_MS) was developed for detecting the significant differences of root exudates of the Cd hyperaccumulator Sedum alfredii under different treatments and study the effect mechanism of S. alfredii tolerating or accumulating the heavy metal Cd. The root exudates were collected after treatment for 4 and 8 days with 0 and 40μmol/L Cd. The collected solution was lyophilized and dissolved with methanol, and after derivatization with methoxyamine hydrochloride and N_methyl_N_trifluoroacetamide, the samples were analyzed by GC_MS. Principal component analysis ( PCA) and orthogonal partial least_squares discrimination analysis ( OPLS_DA) were carried out for pattern recognition and a clear separation among the different treatments was achieved. Twelve compounds which caused the separation among the different treatments were found and identified. With the change of treatments, the relative amount of these 12 compounds revealed different trends, which indicated that the Cd hyperaccumulator S. alfredii could adjust the secretion of root exudates to tolerate or accumulate the heavy metal Cd.

Objective:The drug resistance of E.coli to fluoroquinolones is getting stronger in the recent years.This study aimed at the drug resistance of E.coli induced by fluoroquinolones in vitro,so as to provide a guidance for the rational use of antibiotics and effective control of nosocomial infections.Methods: Drug resistance was induced in vitro by a multi-step method in 10 strains of E.coli from clinical isolates with Ciprofloxacin,Levofloxacin and Gatifloxacin.The minimal inhibition concentration(MIC) of the E.coli was determined by the agar dilution method before and after the induction.Results: After in vitro induction,the E.coli acquired a high resistance(MIC ≥ 128 ?g/ml).And one drug could induce different degrees of resistance to the other two.Conclusion: The MIC of the E.coli induced by fluoroquinolones in vitro was increased by 8 to 8 205 folds compared with that before induction,which demonstrated a gradually developed resistance of E.coli strains to fluoroquinolones.

Objective To present the status of smoking control in the Health and Family Planning System in Hubei Province, and to provide scientific basis for smoking control through secret investigations. Methods During the period from July to August in 2015, 168 sanitary Health and Family Planning institutions were chosen by stratified selection to make questionnaires based on Evaluation Standards for Smoke-free Health and Family Planning Institutions issued by the National Health and Family Planning Commission of the People's Republic of China. Secret investigations were conducted in 165 sampled institutions and comparisons were made between smoke-free environment establishment as well as execution processes according to the fraction after converting into centesimal system (actual score/reserved portion × 100). Results The overall score for smoking control in Health and Family Planning System of Hubei Province has climbed to 79.29 ± 12.40.compared to that of 2011 has increased, but 1.6 lower than the national comprehensive evaluated score of 2014. The score of the city (82.14 ± 10.51) proved to be higher than that of the province (66.51±19.69) and the county, (75.35±13.40);disease control institutions (84.77± 9.45) enjoyed a higher score that the others with lowest scores in medical institutions (72.80 ± 14.95);Xianning won the highest score (88.52±5.12);Jingmen (69.81±5.16) and Xiaogan (67.92±7.98) proved to be the lowest in their scores. Nine regions in 17 embraced a lowest discrepancy of over 30 scores and the highest discrepancy of 50.94 scores between the highest score and the lowest among different institutions;12.73% (21/165) medical institutions had no publicity materials; 5/17 municipal institutions and 3/10 county level institutions were still found selling cigarettes, with only 46.06%(76/165) institutions reaching the standard of banning smoking in indoor places, 21.21%(35/165) institutions still have indoor smoking in non-working places, 1.82%(3/165) institutions have indoor smoking in working places. Only 18 (32.14%) institutions out of 56 medical institutions investigated have established smoking cessation clinics. Conclusions Banning-smoking work is less optimistic in general for Health and Family Planning System in Hubei Province, especially for substratum health and family planning institutions. All kinds of departments should take drastic measures to guaranttee the establishment of smoking-free environment.

Objective To investigate the correlation of anthropometric indicators and blood pressure in children. Methods A total of 6 790 children aged 6 to 13 years were inspected by random sampling. The body mass index (BMI), waist circumference (WC), hip circumference (HC), and blood pressure were measured. The waist/hip ratio (WHR) and waist/height ratio (WHtR) were calculated. The data wrer analyzed by SPSS16.0 statistical software. Results The detection rate of hypertension in children was 5.57%. After controlling for age, both in male and female children, the BMI, WC, HC, WHR, WHtR and systolic blood pressure showed a significant positive correlation by partial correlation analysis (all P<0.05). Both in male and female children, the BMI, WC, HC, WHR, and WHtR were significantly higher in children with hypertension than those in children with normal blood pressure (all P<0.05). Among all subjects, 280 children (4.12%) were obese, 622 children (9.16%) were overweight. The detection rates of hy-pertension were significantly different among obese, overweight and normal weight children (P<0.01). The detection rate of hypertension was significantly higher in obese children than that in overweight and normal weight children. The systolic and diastolic blood pressure were all significantly higher in obese and overweight children than that in normal weight children (P<0.05). Conclusion The hypertension prevalence of children aged 6 to 13 years in Zhengzhou is in the low to median level in the same age groups. The BMI, WC, HC, WHR, WHtR are signiifcantly correlated with blood pressure in both gender, and the correlation is the most obvious in HC.

Objective Boy sexual development is affected not only by age, but also by environment factors .The present study was to survey and evaluate the status of sexual development in boys from Zhengzhou area and to explore their influencing factors. Methods The height, weight, waist circumference, hip circumference, penis and testicles in 3779 boys aged from 6 to 13 years old in Zhengzhou were measured .The penis length and testicular volume of different ages and their influencing factors were compared, and the beginning age and sexual development characteristics were explored .The development of genitalia and pubes were evaluated by Tanner staging criteria and standards, which were divided into five stages. Results There were 3779 boys, including 395 overweight cases (10.45%) and 208 obesity cases (5.50%).The testicular volume and penis length increased by age, which increased slowly at the age of 6 to 11, followed by a rapid increase after the age of 11 year old.Testicular volume increased more rapidly than that of penis length. The medians quartile of testicular volume in overweight group ,obese group and normal group were 2.50 mL, 2.50 mL, 2.00 mL, 2.00 mL,2.00 mL,1.00 mL respectively .The testicular volume in overweight group and obese group were significantly greater than that in nor -mal group (P<0.01) and there were no difference between overweight group and obese group .The penis length in overweight group and obese group were significantly less than that in normal group (P<0.01), and there was no difference between overweight group and obese group.Testicular volume and penis length were positively correlated with age, height, weight, body mass index, waist circumference and hip circumference; the correlation between testicular volume and height, penis length and age were the strongest. The age of development of testicle (average 12.02 years) in urban area was later by 2.73 years than that in the rural area (average 9.9 years), the difference was statistically significant (P<0.001).The age of pubic development (P2) and maturity (P5) was (12.34 ±0.83) years and (12.39 ±1.24 ) years.The incidence of precocity in boys was 0.40%. Conclusion The sexual development of boys from Zheng-zhou area is similar to the results of large scale survey from China .Attention should be paid to the effect of obesity on sexual develop-ment, and early intervention should be given, the occurrence of adverse events of sexual development can be avoided .

Objective To summarize the correlation between cytotoxic T lymphocyte associated antigen-4 (CTLA-4) promoter-49 A/G polymorphism and Graves' disease (GD)in China.Methods The publications before Sep.30,2011 about the correlation between CTLA-4 promoter-49 A/G polymorphism and GD in China were collected by searching CNKI,CBM,and Wanfang database.Meta-analysis was performed to check the difference of genotypes such as AG,GG,GG + AG,and G allele between GD group and the control group.Results A total of 6 studies involving 570 cases in GD group and 486 cases in the control group were included in the meta-analysis.According to the heterogeneity of these studies,meta-analysis was performed to analyze the correlation between AG,GG,GG + AG genotype,G allele and GD by fixed effects model.The pooled OR value(95％ CI) of various studies was 1.97 (1.37-2.82),3.66 (2.42-5.53),2.55 (1.82-3.58),and 1.99 (1.49-2.65).Conclusion The meta-analysis demonstrates that CTLA-4 promoter-49 A/G polymorphism increases the possibility of getting GD in Chinese.

Fed with high-fat diet and assessed by hyperinsulinemia-euglycemia clamp technique, rat models with insulin resistance were successfully induced. Compared with normal chow group ( NC ), serum concentrations of free-fatty acids(FFAs) and baseline insulin in high-fat diet group(HF) was higher( P＜0.05 ), the average glucose infusion rate from 60 to 120 min( GIR60-120 ) was lower( P＜0.01 ), and the expression of p-IRE-lα in the liver was higher( P＜0.05 ). Furthermore, the expression of p-IRE-1α in the liver was positvely correlated with the serum concentration of FFAs. All these data indicate that high-fat diet may induce endoplasmic reticulum stress in the liver by elevating serum concentration of FFAs, and may participate in the genesis of insulin resistance via p-IRE-1α.
