ABSTRACT
Objective To study the change and clinical significance of serum sex hormone levels in patients with Alzheimer's disease(AD).Methods The 1:1 case-control study,male AD group in 25 cases,control group in 25 cases,female AD group in 25 cases,25 cases in the control group.The serum sex hormone levels were measured by chemiluminescence immtmoassay in the two groups,and the data were analyzed.Results There was statistically significant difference in estradiol level between female patients and the control group[(40.820 ± 23.249) pmol/L vs.(153.700 ±113.900) pmol/L,t =4.85,P ＜ 0.001].There were statistically significant differences between male patients and the control group,in estradiol[(99.243 ± 34.657) pmol/L vs.(124.t00 ± 38.432) pmool/L],testosterone [(7.904 ±3.944) nmol/L vs.(19.142 ±7.882) nmol/L] levels (t =2.40,6.37,all P ＜0.05).No significant difference was observed in testosterone level in the female groups (P ＞ 0.05).The promoting follicle stimulating hormone and luteinizing hormone,progesterone,prolactin levels between the male group and female group had no statistically significant differences (all P ＞ 0.05).In patients with simple intelligent screening scale (Mini-Mental State Examination,MMSE),the score was significantly correlated with the level of estradiol (r =-0.281,P ＜ 0.05).Conclusion The level of women's estrogen decline is related to factor in the pathogenesis of AD,estradiol,testosterone levels of male decline is related to factor in the pathogenesis of AD.Estradiol level is low,the severity of the disease moreand more heavy.
ABSTRACT
Objective To understand the risk factors of the elderly in community of Haining city in patients with Alzheimer's disease.Methods Take the elderly Chang street Haining city selected cluster sampling method 7 437 ≥60 years as the research subjects,by using a self-designed questionnaire Alzheimer's disease causes and clinical dementia rating scale,understanding the factors that may affect Alzheimer's disease and aggravating factors,and the data of multi factor regression analysis.Results Multivariate Logistic regression analysis showed that women (Wald x2 =19.96,P ＜ 0.01),aged (Wald x2 =96.01,P ＜ 0.01),widowed (Wald x2 =5.09,P ＜ 0.05),smoking/drinking (Wald x2 =47.77,P ＜ 0.01),living alone (Wald x2 =16.14,P ＜ 0.01),depression (Wald x2 =12.05,P ＜ 0.01) were the risk factors of Alzheimer's disease; Rural (Wald x2 =458.11,P ＜ 0.01) ; Lowculture (Wald x2 =121.39,P ＜0.01) were protective factors for Alzheimer's disease.According to the clinical dementia rating scale of disease severity assessment and pathogenesis of polytomous Logistic regression,the results showed that the elderly (Wald x2 =50.37,P ＜ 0.01),lowculture (Wald x2 =30.39,P ＜ 0.01),widowed (Wald x2 =5.20,P ＜ 0.05),living alone (Wald x2 =16.50,P ＜ 0.01),somatic diseases (Wald x2 =16.58,P ＜ 0.01) and large maternal age (Wald x2 =10.53,P ＜ 0.01) were risk factors for disease.Conclusion Age,widowed,solitude are common risk factors of Alzheimer's disease and aggravating factors,should be combined with risk factors for chronic disease management actively take measures to prevent and delay the occurrence,the development of Alzheimer's disease.
