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.

AIM To study the protective effect of TFA against cerebral ischemia reperfusion injury. METHORDS The cerebral ischemia model in mice was made by means of ligating bilalateral common carotid arteries.The mice survive rate during 6 h was observed,and malondialdehyde (MDA) in the ischemic cerebral cortex was measured. Using nitrogen anoxia model in mice,the survive time was observed. Ligating bilateral common carotid arteries and descending blood pressure,the cerebral ischemia reperfusion model in rabbits was established. The brain of rabbits was initiated by ischemia for 60 min followed by 30 min of reperfusion. The electroencephalogra phy (EEG) of cerebral ischemia and reperfusion was recorded. Malondialdehyde(MDA) and lactate dehydrogenase(LDH) in the ischemic cerebral cortex were measured. RESULTS TFA(30,60,120 mg?kg -1 ) prolonged the survive time after anoxia in mice,enchanced the survive rate after cerebral ischemia and inhibited the increasing of MDA contents in the cerebral cortex in mice.TFA(12,24,48 mg?kg -1 ) inhibitid the changes of EEG,MDA and LDH induced by cerebral ischemia reperfusion in rabbits. CONCLUSION TFA has protective effects on cerebral ischemia reperfusion injury,the mechanism may relate to attenuating free radical and lipid peroxidation.

ObjectiveTo study the factors which affect the nurses' implementation of cardiac rehabilitation. MethodsData of 134 nurses who worked or are working in cardiology ward in No.1 and No.2 hospital of China Medical University was analyzed by using descriptive and inferential statistics.ResultsThe overall barriers is at a moderate level. The types of the barriers in order of mean score were no formal rehabilitation program, lack of knowledge, lack of facility, lack of support, and lack of understanding. Conclusions In order to improve the motivation of nurses to implement cardiac rehabilitation nursing, something must be done to improve nursing practice , nursing administration, and nursing education.

Objective The PRESENT ( Physicians' Routine Evaluation of Safety and Efficacy of NovoMix 30 Therapy) study is a multinational clinical experience program to report the efficacy, safety and acceptability of NovoMix 30 (BlAsp 30) in patients with type 2 diabetes mellitus inadequately controlled with oral antidiabetic drugs (OADs). Methods A total of 4 754 type 2 diabetes patients inadequately controlled with oral antidiabetic drugs were enrolled in the study. All patients were prescribed BIAsp 30 in accordance with the approved labeling. Data were collected at baseline and at the end of 3 months treatment. Results The mean HbA1c, body mass index (BMI), age, and duration were (9.09±1.70)%, (24.30±2.68)kg/m2, (54.63±10.94)years, and (5.46 ±4.17) years separately. The mean daily dose was (0.43±0.14) U/kg at treatment initiation and (0.48±0.15) U/kg after 3 months treatment. After 3 months, the mean HbA1c, fasting plasma glucose (FPG) and postprandial plasma glucose (PPG) were significantly reduced from baseline levels. The mean HbA1c decreased by (2.04± 1.57)%, FPG by a (3.51±2.55)retool/L, and PPG by a (6.51±4.02) mmol/L (all P<0.01). A significant proportion (49.4%) of the patients achieved target HbA1c of ≤7%. The overall rate of hypoglycaemic episodes (events/patient-yr) decreased from 10. 098 at baseline to 3. 810 at study end. The rate of major hypoglycaemia decreased from 0. 787 to 0.126, and the rate of nocturnal hypoglycaemia decreased from 2.356 to 0.547. Compared with previous treatment, more than 99% of the patients and physicians were "satisfied" or "very satisfied" with BIAsp 30 treatment. Conclusions BIAsp 30 was found to be safe and effective to improve the glycaemia control of type 2 diabetes inadequately controlled with OADs in routine clinical practice.

Radioactive 125I interstitial brachytherapy is easy to cause the intestinal tract tissue damage.Its mechanism possibly correlates to the quick renewal speed of the intestinal tract tissue and a majority of ceils in M, G2 and late S phases. The tolerant dose of intestinal tract tissue is approximately 160 Gy. If the absorbed dose is higher than the tolerant one, the intestinal tract tissue will be damaged. In the clinical practice of radio-active 125I interstitial brachytherapy, through the strict plan of the TPS system before the operation, by using ul-trasound, CT, MR/and other imaging technologies in the operating process and establishing the suitable barrier protection between the seeds and intestinal tract tissue, the radioactive damage of the intestinal tract tissue my be reduced.

Objective To evaluate method of CT simulation (CT sim) in the treatment planning setup of esophageal carcinoma. Methods From Dec.1999 to Jun.2002, 49 patients with pathologically proved esophageal carcinoma were analyzed. All patients underwent CT sim and treatment planning was configured with three symmetrical fields in the isocenter mode. A few comparisons have been made between CT sim and conventional simulation (Con sim) in the treatment planning setup. Results The difference in isocenter position were observed between CT sim and Con sim with 3～18 mm.When the esophageal lumen was taken as portal center, the 90% isodose curve in 42.8%(21/49) of patients were able to cover the whole lesion. When taking the tumor as the portal center, the whole lesion of all patients was totally covered by the 90% isodose curve. Conclusion The CT sim has an advantage in the delineation of lateral extension of esophageal tumor than the Con sim .Selection of irradiation portal should be done according to the size the silhouette of the tumor.
