目的 通过Meta分析评估醛固酮合成酶CYP11B2(-344C/T)基因多态性与左心室肥厚之间的相关性.方法 查阅1992年1月至2011年12月发表的有关醛固酮合成酶CYP11B2(-344C/T)基因多态性与左心室肥厚关系的相关研究文献,数据库包括Embase、Pubmed、CNKI(中国期刊全文数据库)、CBM(中国生物医学文献数据库)、VIP(维普中文期刊数据库)及万方数据库.以左心室肥厚组和正常对照组基因分布的OR值为统计量,应用RevMan 5.1软件对各研究结果进行异质性检验和相关数据的合并,最终入选6篇病例对照试验文献,为避免文献间的异质性,将纳入文献分为高血压与种族两个亚组进行分析.结果 共入选左心室肥厚患者541例,对照组553例.左心室肥厚组与对照组CC/(CT +TT),在高血压亚组中OR值1.15(95% CI:0.74 ~1.80),显著性检验Z值为0.63,P=0.53;在种族亚组中OR值1.15(95%CI:0.74 ~ 1.80),显著性检验Z值为0.63,P=0.53.左心室肥厚组与对照组C等位基因/T等位基因频率OR值1.15(95%CI:0.76~1.74)/0.87(95%CI:0.58~1.31),显著性检验Z值为0.67,P=0.50.结论 无论是高血压人群或是不同种族人群,醛固酮合成酶CYP11B2(-344C/T)基因多态性与左心室肥厚无关.
目的 通過Meta分析評估醛固酮閤成酶CYP11B2(-344C/T)基因多態性與左心室肥厚之間的相關性.方法 查閱1992年1月至2011年12月髮錶的有關醛固酮閤成酶CYP11B2(-344C/T)基因多態性與左心室肥厚關繫的相關研究文獻,數據庫包括Embase、Pubmed、CNKI(中國期刊全文數據庫)、CBM(中國生物醫學文獻數據庫)、VIP(維普中文期刊數據庫)及萬方數據庫.以左心室肥厚組和正常對照組基因分佈的OR值為統計量,應用RevMan 5.1軟件對各研究結果進行異質性檢驗和相關數據的閤併,最終入選6篇病例對照試驗文獻,為避免文獻間的異質性,將納入文獻分為高血壓與種族兩箇亞組進行分析.結果 共入選左心室肥厚患者541例,對照組553例.左心室肥厚組與對照組CC/(CT +TT),在高血壓亞組中OR值1.15(95% CI:0.74 ~1.80),顯著性檢驗Z值為0.63,P=0.53;在種族亞組中OR值1.15(95%CI:0.74 ~ 1.80),顯著性檢驗Z值為0.63,P=0.53.左心室肥厚組與對照組C等位基因/T等位基因頻率OR值1.15(95%CI:0.76~1.74)/0.87(95%CI:0.58~1.31),顯著性檢驗Z值為0.67,P=0.50.結論 無論是高血壓人群或是不同種族人群,醛固酮閤成酶CYP11B2(-344C/T)基因多態性與左心室肥厚無關.

Objective To investigate the association between CYP11 B2 gene polymo-rphism and left ventricle hypertrophy with meta analysis.Methods Literatures about the association of CYP11 B2 gene polymorphism and left ventricle hypertrophy from January 1992 to December 2011 were searched.The electronic databases retrieved from Pubmed,Embase,China national knowledge intemet,Chinese biological medicine disk,VIP fulltext database and Wanfang fulltext database.Odds ratio of CYP11 B2 genotype distributions in left ventricle hypertrophy patients comparing with healthy control were analyzed.RevMan5.1 software was applied for investigating hereogeneity among individual studies and summarizing effects with proper statistical methods.Six case control studies were enrolled.Results A total of 541 cases and 553 controls were enrolled for the study.The pooled OR of CC vs TT + TC genotype was 1.15 (95% CI:0.74 ~ 1.80) (Z =0.63,P =0.53) in the subgroup of hypertension,and the pooled OR of CC vs TT + TC genotype was 1.15 (95 % CI:0.74 ~ 1.80) (Z =0.63,P =0.53) in the subgroup of race.The pooled OR of C vs T allele was 1.15 (95% CI:0.76 ~ 1.74) vs 0.87 (95% CI:0.58 ~ 1.31) (Z =0.67,P =O.50).Conclusion Whether the hypertension or the race,the genotype of CYP11 B2 polymorphism has no association with an increased risk of left ventricle hypertrophy.
