To evaluate the association between D2 dopamine receptor gene -141C Ins/Del polymorphism and heroin dependence in Chinese Han population.
Chinese and foreign databases were searched for relevant articles published from the establishment of database to March 2014. Case-control studies on D2 dopamine receptor gene -141C Ins/Del polymorphism with heroin dependence in Chinese Han population were gathered with Meta-analysis by Stata 12.0 software after data abstraction.
Seven case-control studies on association between D2 dopamine receptor gene -141C Ins/ Del polymorphism and heroin dependence were included, which covered 3 211 heroin dependence patients and 1 979 controls. Meta-analysis results showed that the pooled odds ratio (OR), the 95% confidence interval (CI) and P value after combining genotypes were as follows: Ins/Ins vs Del/Del: OR=0.51, 95% CI: 0.27-0.96, P=0.017; Ins/Ins vs Ins/Del+Del/Del: OR=0.82, 95% CI: 0.72-0.94, P=0.448; Ins/Ins+ Ins/Del vs Del/Del: OR=0.53, 95% CI: 0.28-0.98, P=0.019; Ins/Del vs Del/Del: OR=0.59, 95% CI: 0.32-1.07, P=0.045; Ins vs Del: OR=0.79, 95% CI: 0.71-0.89, P=0.101).
D2 dopamine receptor gene -141C Ins/Del polymorphism is associated with heroin dependence in Chinese Han population, and Chinese Han population with Ins allele gene deletion are at lower risk of heroin dependence.
评估D2多巴胺受体基因-141C Ins/Del多态性与中国汉族人群海洛因依赖之间的关联。
检索中外数据库中从数据库建立至2014年3月发表的相关文章。提取数据后，采用Stata 12.0软件对中国汉族人群中D2多巴胺受体基因-141C Ins/Del多态性与海洛因依赖的病例对照研究进行Meta分析。
纳入7项关于D2多巴胺受体基因-141C Ins/Del多态性与海洛因依赖关联的病例对照研究，共涵盖3211例海洛因依赖患者和1979例对照。Meta分析结果显示，合并基因型后的合并比值比（OR）、95%置信区间（CI）及P值如下：Ins/Ins与Del/Del比较：OR = 0.51，95% CI：0.27 - 0.96，P = 0.017；Ins/Ins与Ins/Del + Del/Del比较：OR = 0.82，95% CI：0.72 - 0.94，P = 0.448；Ins/Ins + Ins/Del与Del/Del比较：OR = 0.53，95% CI：0.28 - 0.98，P = 0.019；Ins/Del与Del/Del比较：OR = 0.59，95% CI：0.32 - 1.07，P = 0.045；Ins与Del比较：OR = 0.79，95% CI：0.71 - 0.89，P = 0.101）。
D2多巴胺受体基因-141C Ins/Del多态性与中国汉族人群海洛因依赖相关，携带Ins等位基因缺失的中国汉族人群海洛因依赖风险较低。
