Objective To explore the risk factors of esophageal cancer and these factors' interaction Methods 472 new diagnosed cases of esophageal cancer in 2004—2005 and 472 controls were investigated by case-control study. Etiological fractions and interactions between family history of esophageal cancer and other risk factors of esophageal cancer were analyzed. Results The significant independent risk factors included taking hot-meal, preferring pickled-vegetables, preferring dry-rigidity-food, being irritable, drinking polluted-water perennially, family history of esophageal cancer and drinking alcohol a great deal. The etiologic fractions attributable to interaction were 0.855, 0.758, 0.683, 0.464, 0.459, 0.343 and 0.108 respectively. The synergy indexes of family history of esophageal cancer with taking hot-meal and with preferring dry-rigidity-food were both 0.86. Concludes The interactions between family history of esophageal cancer and ill life-behavior-style or drinking polluted-water perennially were particularly significant in the development of esophageal cancer in Dongping County.

Objective To explore the specific anti-tumor effect of cytokine-induced killer cell (CIK) activation by dentritic cells (DC) loaded with the tumor antigen from human lung cancer cell line A549. Methods CIKs and DCs derived from the health donor's peripheral blood monocyte (PBMC) were isolated and induced by the cytokine in vitro. DCs were generated by culture of adherent cells from PBMC for 7days in the presence of IL-4 and GM-CSF. CIKs were generated by culture of non-adherent cells for 7 or 14 days in the presence of INF-?, IL-2, IL-1?, and mouse anti-human CD3 monoclonal antibody. The phenotype of DC and CIK was analyzed by FCM. The activity of DC was evaluated by MLR; and the cytotoxicity of CIK was assayed by MTT. The CIK expression profile of cytokine and signal transduction genes were detected by the DNA micro-array under different circumstances. Results Phenotypic analysis indicated that CD3+CD56+NKT cells were predominant in the CIK cells generated in the current study, and that DC cells expressed high levels of CD40, CD80, CD86 and HLA-DR. As demonstrated by MTT assay, the CIK cells proliferated rapidly, and the DC cells were able to induce an MLR. Both antigen-pulsed and unpulsed DC stimulated the proliferation of CIK cells, and no significant difference was found between the two kinds of DC cells. Unpulsed DC cells did not enhance cytotoxicity mediated by CIK cells even though they were able to stimulate CIK proliferation. Antigen-pulsed DC, however, stimulated CIK cells to specifically kill target cells. The specific antitumor effect was also observed in nude mice bearing tumors. Conclusion One of the major effects of antigen-pulsed DC is to activate CIK cells and to make them specific in killing tumor cells.

Objective To explore the extent and severity of cognitive dysfunction in patients with schizophrenia and in order to offer more credible evidence to the treatment of schizophrenia. Methods Eighty-eight patients with schizophrenia and Fifty healthy controls in Shaoxing city were measured with Wechsler Memory Scale (WMS-RC), Wechsler Adult Intelligence Scale (WAIS-RC), Cancellation Test (CT) and Wisconsin Card Sorting Test (WCST). Results There was statistically significant difference between the two groups in visual recognition, visual reproduction, 1→100, 100→1, accumulation, picture remember, associative learning, touch test, logical memory, reciting figure and memory quotient of WMS-RC (t=2.40, 4.66, 2.90, 3.48, 4.03, 4.40, 2.13, 3.01, 3.97, 2.29, 4.87, respectively; P

Objective To study the effect of cognitive treatment on the compliance for medication and recrudescence of patients with schizophrenia.Method 106 schizophrenic patients were randomly allocated to the study and the control; both groups treated with antipsychotic medical treatment and health education, while the study group also accepted cognitive psychotherapy. Before treatment and at the ends of 0, 6, 12 months of treatment, the efficacy were investigated using the Brief Psychiatric Rating Scale (BPRS), Insight and Treatment Attitude Questionnaire (ITAQ) and Self-designed Compliance Survey in order to assess the compliance and the recrudescence. Results All the indexes after cognitive psychotherapy were significantly better than those before cognitive psychotherapy. Conclusion The cognitive psychotherapy can effectively reinforce the compliance of patients with schizophrenia, and then improve the quality of life for them.

Objective To analyze the relationship between serum lipids level and different stroke subtypes. Methods 120 cases with stroke were divided into two groups randomly: cerebral infarction stroke(60)and hemorrhage stroke (60). 50 non-stroke cases were chosen as control group. Four indexes for blood lipids were determined in all patients. Results Levels of TG, TC, LDL-C in patients with cerebral infarction were significantly higher than those in the control group. There was no significant difference in serum lipid levels between the patients with cerebral hemorrhage and the controls. Conclusions It suggests that disturbance of serum lipid metabolism is a risk factor for cerebral infarction stroke, but no significant relationship was found between cerebral hemorrhage stroke and blood lipids disorder.

Objective To analyze the risk factors for shortterm recurrence of cerebral infarction. Methods The age, gender, blood pressure, blood sugar, serum triglyceride, serum cholesterol, blood coagulation, atrial fibrillation, intaking of tobacco and alcohols, and body mass index (BMI) were detected in the patients with initial cerebral infarction. During the follow-up of 2 years, they were observed on the factors that might be associated with the recurrence of cerebral infarction. Results By single factor analysis, hypertension, hyperglycemia, high blood lipid, high serum cholesterol, high blood fibrinogen, atrial fibrillation, heavy smoking, excessive drinking, obesity were significantly associated with the recurrence of cerebral infarction in the two-years follow-up(P

Objective To explore the relationship between smoking, alcohol drinking and gallstone disease in general male population in Guangdong. Methods Each subject received a questionnaire and took an upper abdominal ultrasound examination in a cross-sectional study. Results The prevalence of gallstone disease became higher with the increase of amount of cigarette smoking per day (trend test ?2=5.542, P=0.019) and with the total amount of cigarette smoking in their life (trend test ?2=7.302, P=0.007), these significance remained after controlling well-known risk factors for gallstone disease such as age and body mass index (BMI) (OR=1.269,95%CI: 1.018~1.580 for cigarette smoking per day and OR=1.295, 95%CI: 1.020~1.646 for total ). Little to moderate alcohol drinking (

Objective To investigate the relationship between CRP and CK-MB among acute and stable patients with COPD in Nanjing city. Methods Using case-control design, 81 COPD patients and 71 normal controls were selected. Both fasting venous and arterial blood samples were collected for COPD patients at the acute and the stable stage separately, while fasting venous blood samples were collected for controls during medical examination. The concentrations of CRP, CK-MB or PaO2 of all blood samples were examined. Results The concentration of CRP and CK-MB were significantly higher among stable COPD patients (7.18?5.62, 10.92?5.33; respectively) than those among controls(3.00?0.91, 3.11?1.46; respectively), while acute patients (51.22?24.53,30.06?16.68; respectively) got much higher concentration of CRP and CK-MB than stable patients did. However, PaO2 was significantly higher among stable COPD patients than that among acute patients. For acute COPD patients, the concentration of CK-MB positively correlated with CRP, while PaO2 negatively correlated with CRP and CK-MB separately. Conclusions CRP and CK-MB were sensitive predictors of COPD status to the transition from stable to acute stage of COPD, and both negatively correlated with PaO2 among these sample COPD patients.

Objective To explore methods for hypertension intervention healthy promotion, improve villagers 'healthy consciousness and facilitate their behavior change in country. Methods Adopted "point to lead side and point combine with side" to develop community diagnosis and mobilization, establish system for measuring blood, organize villagers abstain from tobacco and supervise those who with hypertension in experimental village. Use self comparison to evaluate intervention effects. Results Understanding rate(full understanding means knowing all parts of the project ) about the clinical manifestation and harmful influence of hypertension have increased from 2.0% to 10.4% and 0.2% to 8.7% respectively just after intervening, but preventive knowledge level hasn't improved obviously between 2003(before intervening) and 2006(after intervening).Before 2003, There were no villagers have ever measured their blood pressure on their own, and the rate of medical workers who have measured blood pressure for patients on their own was 28.5%. But after 2006, the rate of villagers who know ought to measure blood pressure periodical was 97.6%, and among them, 83.0% have measured their blood pressure on their own. Medical workers who have measured blood pressure for patients increase to 80%~90%. Through medical institution launching a program named " measuring blood pressure for above 35 years free charge", 137 822 hypertensive were found in 3 years in 6 item country 256 health institutions of township and village levels. Among those 51 505 were found freshly. Conclusion We adopted a series of measures, which were take countryside government to be guidance, take village hospital to be technical support, take village hospital to be flat, take village committee to be support and take villagers prescript to be obligation. Through every intervention, we improved villagers' healthy consciousness and facilitated their behavior change. Trough" measuring blood pressure for above 35 years free of charge", it can make more hypertensive get diagnosis and therapy timely.

Objective To explore the death distribution characteristics of heart disease and the strategies for its prevention and control, based on data of the death rates of different heart diseases among the residents of Henan province from 1987 to 2006. Methods The mortality rates of heart diseases during past 20 years were analyzed by age, sex, living places (urban vs. rural), and by patterns of heart disease as well with SAS9.1. Results In these past 20 years, the mortality rates of heart diseases ranged from 60.93 to 85.10 per 100 000. The annual mortality rate averaged 74.47 per 100 000, and the standardized mortality rate was 61.10 per 100 000, which equaled to 13.14% of the total death number. The death rates of heart diseases had increased significantly with age. Among the male and female of the cities or the rural, the death was mainly due to coronary heart disease. Concludes According to the death distribution characteristics of heart diseases in Henan Province, the prevention and control efforts should focus on the population over 35 years of age.
