Objective The article aimed to investigate the correlation of lipid profile levels with deoxyribonucleic acid (DNA) damage and total antioxidant capacity (TAC) levels in obese pregnant women. Methods Healthy pregnant women (n=120 ) who took routine prenatal care from August 2011 to August 2012 in our hospital were recruited .All the pregnant women were di-vided into normal weight group ( n =45 ) and obese group ( n=75 ) .The lipid profile levels , DNA damage and TAC levels of two groups were compared and analyzed , and the correlations among lipid profile levels , DNA damage and TAC levels were analyzed . Results Compared to normal weight group , obese group showed significantly higher levels of TC (P=0.000), TG(P=0.000), and LDL-c(P=0.004), but a lower level of HDL-c (P=0.006).The DNA damage and TAC level of obese group were obviously higher than those of normal weight group (P=0.000, P=0.000).The DNA damage was positively correlated with levels of TC , TG and LDL-c among obese pregnant women (r=0.23, P=0.026;r=0.26, P=0.008;r=0.19, P=0.032), and TAC level was positive-ly correlated with TG level (r=0.32,P=0.000). Conclusion Dyslipidemia, imbalance of prooxidant and antioxidant status al-ways occur to obese pregnant women .The DNA damage is positively correlated with levels of TC , TG and LDL-c among obese pregnant women, and TAC is positively correlated with TG level .

Objective:To identify the HLA-A0201 restricted CTL epitopes derived from hepatitis B virus X protein predicted by computer program and general principles in vitro.Methods:HBx gene sequences of Hepatitis B virus genotypes B/C and serotypes adw/adr,with the highest frequencies in Chinese,were computed and analyzed by screening service offered by Internet combined with peptide supermotif,extended motif and quantitative motif prediction.Four most ideal nine-peptides(HBx1,HBx2,HBx3,and HBx4)were selected as candidate peptides.Using flow cytometry,the fluorescence index of both control and experimental groups were detected and the 4 nine-peptides were evaluated with T2 binding assay and DC50 assay.Results:The nine-peptides VLCLRPVGA(HBx1),CLFKDWEEL(HBx2),VLHKRTLGL(HBx3)and HLSLRGLPV(HBx4)were selected as candidate targets.Among the 4 candidate peptides,HBx2 showed higher HLA-A0201 affinity and HBx2,HBx4 showed better stability.Conclusion:Our study indicates that CLFKDWEEL might be a potential HLA-A0201 restricted CTL epitope from hepatitis B virus X protein;further study is needed for verification of its immunity in vivo.

Objective To determine the incidence rate of HPV infection or multi-infections at different stages of cervical lesions in the development of cervical cancer , and the impact of specific types of HPV multi-infections on the risk of cervical cancer. Methods 103 samples of cervical tissues were detected and then divid-ed into ICC/HSIL group and LSIL/NILMF group according to the degree of pathological changes. HPV type was determined by PCR product sequencing. E6 nested multiplex PCR was performed to detect HPV multi-infections. Odds ratios were calculated to determinate the association between the sample category (LSIL/NILM or ICC/HSIL) and the specific types of HPV multi-infections. Results In HPV-positive samples, the rate of multi-in-fections had no significant differences between the two groups. Coinfection of HPV68 with HPV16 increased the risk of ICC/HSIL, as compared with HPV16 or HPV68 infection alone. Conclusions High-risk HPV coinfec-tions has a higher risk to induce ICC/HSIL than does HPV infection alone.

Objective: To examine the association between neonatal birth weight and maternal type 2 diabetes (T2DM), so as to provide insights into the formulation of the early T2DM prevention and improvements of maternal and children health. Methods: Single-nucleotide polymorphisms (SNPs) were collected from two genome-wide association studies (GWAS) that examined the association between neonatal birth weight and maternal T2DM. Inverse variance weighted method was employed for forward Mendelian randomization with 26 birth weight-associated SNPs as instrumental variables and maternal T2DM as the study outcome and for reverse Mendelian randomization with 18 maternal T2DM-associated SNPs as instrumental variables and maternal effects of neonatal birth weight as the study outcome. The heterogeneity was examined using Cochran's Q test, and the pleiotropy was evaluated using MR-Egger regression, while the robustness of the results was evaluated using leave-one-out test. Results: Cochran's Q test detected heterogeneity across two studies (P=0.019, 0.038), and random effect models were employed. Mendelian randomization showed that an increase in neonatal birth weight by per standard error (approximately 488 g) resulted a 29.9% reduction in the risk of maternal T2DM (OR=0.701, 95%CI: 0.547-0.899), and maternal T2DM increased the neonatal birth weight by 0.074 standard errors (OR=1.074, 95%CI: 1.043-1.106). No horizontal pleiotropy was seen for instrumental variables (P=0.241, 0.188). With each SNP excluded in turn, the results of Mendelian randomization study were robust. Conclusion There are bidirectional associations between neonatal birth weight and risk of maternal T2DM.

Objective To assess the clinical efffects off Ipratropium bromide combined with atomization inhalation of budesonide via a ventilator with a Y-shaped connector on acute exacerbation off chronic obstructive pulmonary disease (AECOPD).Methods A total off 62 AECOPD patients treated at our hospital from June 2013 to September 2014 were randomly divided into the experimental group (n=31,treated with ipratropium bromide combined with atomization inhalation of budesonide) and the control group (n =31,treated with the same amount of saline).Results The airway pressure of mechanical ventilation,the time of mechanical ventilation and the time of staying in the intensive care unit all showed significant differences between the experimental and control groups [(25.4±5.2) cmH2O vs.(38.1±3.4) cmH2O,(6.5±1.3) d vs.(6.8±1.4) d,(8.9±2.1) d vs.(9.5±1.5) d,t=10.934,0.960,1.108,respectively,P＜0.05 for all].The rate of tracheotomy was lower in the experimental group than in the control group (17/31 or 54.8％ vs.20/31 or 64.5％,x2 =0.603,P＜0.05).Conclusions Ipratropium bromide combined with budesonide inhalation under mechanical ventilation via a Y-shaped connector has ffavorable clinical effects on AECOPD.

To investigate the curative effect of electroacupuncture on luteinized unruptured follicle syndrome(LUFS) and its mechanism. Methods:Sixty LUFS patients were randomly allocated to treatment (electroacupuncture) group and control (hCG) group. The follicular condition and ovarian arterial flow under color Doppler ultrasonogaphy and a change in reproductive endocrine level were observed in the patients before and after treatments. The ovulation rates and pregnancy rates were compared between the two groups,and the mechanism was investigated. Results:Both ovulation rate and pregnancy rate were significantly higher in the treatment group than in the control group (P＜0.01). There was a significant difference in the improvement in ovarian arterial flow between the treatment and control groups (P＜0.01). The improvement in endocrine level was significantly more marked in the treatment group than in the control group(P＜0.01). Conclusion:Electroacupuncture has a good effect on luteinized unrupture follicle syndrome. Its mechanism may be related to the improvement in ovarian arterial blood supply and the regulation of endocrine level.

Objective This study was carried out to compare chnical efficiency of methylprednisolone (MP) and dexamethasone (Dex) and their effects on Th cytokines in asthmatic children.Methods A total of 39 children with moderate and severe asthma at acute exacerbation were randomly divided into two groups, one (A) with MP 1 -2 mg/kg (n=21) and the other (B) with Dex 0.25 -0.75 mg/kg (n= 18),every 12 -24 h by intravenous drip.Scores of respiratory effort and peak expiratory flow rate prior to and three days after treatment in the asthmatic children aged over five years were evaluated,respectively,as well as the time of wheezing vanishing after treatment.Serum levels of interleukin-2 (IL-2) and IL-4 were determined by radioimmunoassay (RIA) prior to and three days after treatment,respectively.Results There was statistically significant difference in the time of wheezing vanishing between groups A and B (P = 0.042).Three days after treatment,PEER was significantly higher in group A than that in group B (P = 0.025).No statistically significant difference in serum IL-2 and IL-4,as well as ratio of IL-2/IL-4,was found in group B prior to and three days after treatment (P>0.05).Statistically significant difference in serum IL-2 was not observed in group B prior to and three day after treatment (P>0.05),and serum IL-4 decreased significantly (P=0.001) and ratio of serum IL-2/IL-4 (P=0.027) increased significantly three days after treatment than those prior to treatment.No significant correlation between respiratory-effort scores and ratio of serum IL-2/IL-4 prior to treatment was found (P=0.613).Conclusions Up-regulation of IL-2,or inhibition of release of IL-4,probably is not the main anti-inflammatory mechanism of dexamethasone.Methylprednisolone has little effect on serum IL-2,but can effectively reduce serum IL-4, thus increasing the ratio of serum IL-2/IL-4 and counterbalancing function of the Thl/Th2 cells.
