Objective To investigate the relationship between hOGG1 and XPD gene polymorphism and genetic susceptibility of gastric cancer.Methods This study was carried out in Dongying Shengli Petroleum Administration Bureau Hospital.Under the narrow band imaging(NBI) mode,the blood samples of a total of 98 gastric cancers and 80 controls without cancers were collected.Genetic polymorphisms of DNA repair genes were identified by polymerase chain reaction restriction fragment length polymorphism(PCR-RFLP),then its relationship with cancers was analyzed.Results Carrying 326Cys allele with the wine increased the risk of gastric cancer; Lys 751Gln genotype increased the susceptibility of the gastric cancers (OR =1.486,0.73 ～ 3.025).Conclusion Lys751 Gln genotype increases the risk of gastric cancer.

Objective: To investigate the composition and clinical features of inpatients with congenital heart disease (CHD) complicated with pulmonary arterial hypertension (PAH) from a cardiovascular department. Methods: We retrospectively analyzed the clinical data of 238 PAH patients who were identified from 3 674 CHD inpatients in Changhai Hospital during Jan, 2001 to Jul, 2007. Results: Among the 3 674 CHD inpatients who were treated in our hospital in recent 6 years, 238 (6.48%) had PAH. PAH was found in 10.8% of patients with atrial septal defect (ASD), 2.81% of patients with ventricular septal defects (VSD), 5.57% of patients with patent ductus arteriosus (PDA), and 19.6% of patients with complex types. The mean age of patients was (45.6 ± 17.7) years, with 49.6% of them being 40-60 years. Female patients accounted for 69.3% of the total. The composition of PAH patients was: ASD (62.6%), VSD(19.7%), and PDA(13.4%). The patients with VSD, PDA or other complex types were younger than those with ASD(P<0.01). More female PAH patients had ASD than VSD (76.5% vs 44.7%,P<0.01). Most patients had chest distress and dyspnea on exertion as initial symptoms and accentuated pulmonary component of the second heart sound as physical sign; they also had increased cardiothoracic ratio, prominent, dilated central pulmonary arteries on chest radiography, right ventricle enlargement, and incomplete right bundle branch block on ECG. The pulmonary artery systolic pressure(sPAP), as estimated by echocardiography, had a significant correlation with catheterization measurements(r=0.734,P<0.01). Conclusion: PAH is common in patients with CHD, especially in females, those with ASD, and those of 40-60 years old. The clinical presentation, chest radiography and ECG are normal. Echocardiography has important diagnosis value. There is a correlation between echocardiography and catheterization measurements of sPAP.

Objective:Matching pursuit algorithm(MAP),for its good parametric characterization, is applied in Magnetoencephalography(MEG) to study time-frequency distribution. Methods:This paper proposes to apply a high-resolution time-frequency analysis algorithm, the matching pursuit (MP), to extract detailed time-frequency components of SEF signals. Results: Experimental results on cortical SEF signals of several normal subjects show that a series of stable SEF time components can be identified using the MP decomposition algorithm. Conclusion:This study shows that there is a set of stable and minute time-frequency componentsin SEF signals, which are revealed by the MP decomposition. These stable SEF components have specific localizations in the time domain and may provide a reliable index for clinical research of brain function and brain disease pathogenesis.

Objective To assess the impact of parents' occupational class and intergenerational occupational mobility on children's mental health so as to provide evidence for improving health equity.Methods Chinese general social survey 2005 (CGSS2005) dataset was used for multivariate analysis of variance (MANOVA).Results The proportion of children whose father or mother was of lowerclass occupation was 59.0％ and 62.9％,respectively.When grew up,this figure dropped to 49.8％.Those whose father was in the higher-class occupational group reported better mental health status (F =1.449,P=0.015).Downward occupational class mobility experience also increased the risk of mental illness (F =3.050,P =0.048).Conclusion This study suggests an independent relationship between mental health and parents' occupational class and intergenerational occupational mobility.

Objective To investigate the effect of coenzyme Q10 combined with Shenmai injection on serum enzyme in the treatment of brain hypoxic injury after asphyxia by meconium in newborn.Methods 64 cases with brain hypoxic injury after asphyxia by meconium from Medical University of Tianjin Jinghai Clinical College were selected and randomly divided into 2 groups, 32 cases in each group.The control group received maintained ventilation and circulation function and routine drug therapy adequate, and the experiment group received more with coenzyme Q10 combined with Shenmai injection for 7 days.Serum enzymes and myocardial injury markers, oxidative stress and inflammation related factors and the clinical effect and complications were compared after the treatment.Results Compared with before treatment, levels of CK-MB, AST, LDH, CK and α-HBDH decreased in two groups after the treatment, levels of CT-1, CTnI and Mb decreased, levels of SOD and MDA decreased, contents of GSH-Px, APN, IGF-1 increased, contents of Leptin decreased (P<0.05).Compared with the control group, the levels of CK-MB, AST, LDH, CK and α-HBDH in the experiment group were lower, levels of CT-1, CTnI and Mb were lower, levels of SOD and MDA were lower, contents of GSH-Px, APN, IGF-1 were higher, contents of Leptin were lower(P<0.05).The clinical curative effect rate of control group(65.63%) was lower than the experiment group (87.50%)(P<0.05).Conclusion Coenzyme Q10 combined with Shenmai injection in the treatment of brain hypoxic injury after asphyxia by meconium in newborn is curative effective with high safety, and it can reduce serum enzyme and myocardial injury.
