| 摘 要： | 目的:探讨脑源性神经营养因子(brain-derived neurotrophic factor,BDNF)基因G196A住点多态性与抑郁症患者负性生活事件的相关性.方法:对85例抑郁症患者(抑郁症组)和158名健康人(对照组)进行BDNF基因G196A基因型检测和生活事件量表(life events scale,LES)评分,比较2组的结果,分析G196A位点多态性与负性生活事件的相关性.结果:抑郁症组的LES中总生活事件、负性生活事件、正性生活事件评分均高于对照组.抑郁症组G等位基因频率为70%(119/170)、A等位基因频率为30%(51/170);对照组相应为51.3%(162/316)、48.7%(154/316),2组比较差异有统计学意义(P<0.05).抑郁症组G等位基因频率与负性生活事件呈正相关(P<0.05,优势比为3.102,95%可信区间为1.118～8.609);A等位基因频率与负性生活事件呈负相关(P<0.05,优势比2.962,95%可信区间为1.038～8.451).结论:BDNF基因G196A位点G等位基因可能是抑郁症患者对负性生活事件敏感的遗传基础.

| Abstract: | Objective:To investigate an interaction between the genetic polymorphisms(G196A)of brain-derived neurotrophic factor(BDNF)and negative life events in patients with depressive disorders.Methods:Genotype of 85 depressive disorders patients(DD group)and 158 healthy controls(control group)were identified by polymerase chain reaction(PCR).Life events were evaluated using a life events scale(LES),the results of two groups were compared.An interaction of BDNF genetic polymorphisms and negative life events was anal... |
