摘要
目的探讨缺血性脑卒中(IS)后CIND的危险因素及与ACE I/D的交互作用。方法以19~80岁盐亭县人民医院汉族初发IS患者作为研究对象,发病后3月采用简易智能量表(MMSE)和美国精神疾病统计和诊断手册第4版修订本(DSM-Ⅳ-R)进行认知测定,检测ACE I/D多态性,采用Logitic回归分析研究CIND患者的传统危险因素和易感基因以及交互作用;结果共纳入研究对象235例,212例完成3月随访和认知测试,其中27例诊断为痴呆被排除,42例诊断为CIND(22.7%)。分析发现,大面积和中等面积梗死(OR=4.687,P<0.05; OR=4.734,P<0.05)、糖尿病(OR=2.887,P<0.05)、DD基因型(OR=2.852,P<0.05)是IS后CIND的独立危险因素。然而,没有发现有统计学意义的交互作用;结论糖尿病、梗死大小、ACE DD基因型是IS后CIND的独立危险因素。
Objectives To determine the genetic and environmental risk factors in cognitive impairment no dementia(CIND) after ischemic stroke(IS), as well as whether there was evidence of gene-environment interactions. Methods The samples consisted the Han people with first-ever IS at the age of ranging from 19 to 80 years. The ACE I/D polymorphism was detected by polymerase chain reaction(PCR), and the possible risk factors involved in CIND were collected in detail. The cognitive function was evaluated at 3 months after IS according to the Chinese version of Mini-Mental State Examination(MMSE) and Diagnostic and Statistical Manual of Mental Disorders(DSM-Ⅳ-R). Univariate and logistic regression analysis was used for statistical analysis. Results 235 patients were entered into the study and 212 patients were evaluated at the post-IS 3 months. 185 were performed statistical analysis after exclusion of 27 patients with dementia, and 42 patients were diagnosed as CIND. Multivariate logistic regression suggested that the diabetes(OR=2.887, P<0.05), infarct volume(OR=4.734, P<0.05) and ACE DD genotype(OR=2.852, P<0.05)might be independent risk factors of CIND after IS, however, there was no evidence of interactions. Conclusion Diabetes, infarct volume and ACE DD genotype are associated independently with post-IS CIND.
