摘 要:[目的]探讨低密度脂蛋白受体相关蛋白(LRP)C766T基因多态性与Alzheimer病(AD)的关系。[方法]采用Review Manager 4.2软件,对国内外近10年(2000~2009年)公开发表的有关LRP C766T多态性与AD的关系研究的18篇文献(AD组3 433例,对照组3 922例)的研究结果进行Meta分析。[结果]总体效应检验显示,AD组和对照组C等位基因频率和CC基因型频率差异无统计学意义。随机效应模型OR值及其95%CI分别为1.14(0.97~1.33)和1.06(0.90~1.26)。按照种族分层进行亚组分析发现,对于亚洲人群,携带C等位基因或CC基因型者发生AD的风险分别是未携带者的1.70倍(OR值95%CI:1.35~2.14)和1.49倍(OR值95%CI:1.01~2.20)。对于中国汉族,这种关联强度更为明显,携带C等位基因或CC基因型发生AD的风险分别是未携带者的1.83倍(OR值95%CI:1.43~2.34)和1.89倍(OR值95%CI:1.43~2.50)。[结论]总的来说,尚不能认为LRP C766T多态性与AD有关,但对于亚洲人群,特别是中国汉族,LRP C等位基因和CC基因型过度表达很可能是AD的危险因素之一。[Objectives] To explore the association of low density lipoprotein receptor-related protein gene(LRP) C766T polymorphisms with Alzheimer’s Disease(AD).[Methods] With Review Manager 4.2,we performed a Meta-analysis of 3 433 AD patients and 3922 matched controls drawn from eighteen case-control studies which assessed the association be-tween the LRP C766T polymorphisms and Alzheimer’s disease.[Results] The combined data statistics revealed that there was no statistical difference in the frequencies of C allele(OR=1.14,95%CI: 0.97-1.33) and CC genotype(OR=1.06,95%CI: 0.90-1.26) between AD patients and control subjects.But the effect becomes statistic significant when the data was stratified by ethnic,those who having C allele or CC genotype being roughly 1.70(OR95%CI: 1.35-2.14) or 1.49 times(OR95%CI: 1.01-2.20) more likely to have AD among Asians.To the Chinese Han people,the association becomes stronger,the OR is 1.83(1.43-2.34) or 1.89(1.43-2.50) separately.[Conclusion] Generally speaking,there is no evidence for the involve-ment of LRP C766T polymorphisms in increasing the susceptibility to AD.However,the over expressed C allele and CC geno-types are very likely to be the risk factors among Asian,especially Chinese Han People.
