Objective To investigate the factors of Alzheimer’s Disease (AD). Methods A 1:1 matched case-control study was conducted. The study included 129 patients of clinically diagnosed AD and 129 controls selected from Nanchang and Jiujiang areas. The data were analyzed by the conditional logistic regression. Results The results showed the unsociable personality (OR=2.486,95%CI=1.075～6.638),the history of great negative life events (OR=4.125,95%CI=1.706～12.249),using cookers made of aluminum (OR=2.454,95%CI=1.277～5.268) were identified as risk factors for AD. The good family income state (OR=0.324,95%CI=0.106～0.828) and frequently physical exercises (OR=0.258,95%CI=0.104～0.520) were protective factors for AD. Conclusion Alzheimer’s Disease seems to be related to the income state,frequency of physical exercises,personality,big negative life events,using cookers made of Aluminum.

OBJECTIVE: To explore the safety of different dosages of simvastatin in patients with dyslipidemia. METHODS: 269 patients with essential dyslipidemia were randomly assigned to receive simvastatin (5, 10 or 40 mg?d-1) for 8 weeks. The curative efficacy and the adverse reactions were compared among groups. RESULTS: There were significant differences across the 3 groups (5, 10 or 40 mg?d-1) with regard to the total effective rates on regulating total cholesterol, triglyceride, high-density lipoprotein cholesterol(P0.05). The total incidence of ADRs was 14.87%, which appeared mainly as gastrointestinal reaction and myosalgia, and the differences across the 3 groups were significant (P=0.03), but no significant difference was noted with regard to sex and age (P=0.46,P=0.07). CONCLUSION: Simvastatin may induce ADRs, but in most cases the ADRs were mild,and the incidence of the ADRs increased as the dosage of simvastatin increased.Tailoring the dosage of simvastatin to patients’ clinical characteristics is conducive to patients’ medication safety.

To investigate the ageing status for male population aged or over 20 years old in urban communities, clarifying their distribution characteristics and rules, and to provide reference for aging research.
 Methods: A total of 1 120 men aged or over 20 years old in Nanchang were obtained by stratified sampling, and the aging scale was measured in 9 groups. The distribution characteristics of aging scores were analyzed by normality test, variance analysis, and linear correlation.
 Results: The total score of aging and the scores of physiological, psychological, and physiological dimensions were 54.01±9.24, 32.33±7.54, 14.66±1.64, and 7.02±1.16, respectively. The scores were positively correlated with age. The total score curve of aging was significantly increased in the 25-<30 and 30-<40, 65-<70 and 70-<75 years old groups. The physiological dimension curve was similar to the total score curve. The psychological dimension curve was more pronounced at 55-<60 and 60-<65 years old groups. The social dimension curve raised slowly and smoothly at all ages.
 Conclusion: The total score and the scores for all dimensions of male physiological-psycho-sociological increase with age; and changes near the age group of 55-<60 and 60-<65 are obvious, providing reference for the understanding of male aging.
