摘 要:目的系统评价过氧化物酶体增殖物活化受体12(peroxisome proliferator activatedreceptor γ2,PPARl2)基因Pro12A1a多态性与妊娠期糖尿病(gestational diabetes mellitus,GDM)的相关性。方法检索PubMed、The HuGE Navigator、中国知网、万方数据库和维普科技期刊全文数据库中关于Pro12A1a多态性与GDM发病风险遗传关联性的病例对照研究。检索时限均为建库至2014年12月1日。由2名评价员分别进行文献筛选、数据提取和质量评价,采用RevMan5.3软件对纳人文献中的数据进行meta分析。结果共纳入13篇文献,其中中文文献6篇、英文文献7篇,2787例GDM患者和5408例对照者。13篇文献纽卡斯尔渥太华量表质量评分均≥5,质量较优。Meta分析结果显示:(1)总体评价:PPAR12基因Pr012A1a多态性(等位基因A1a或基因型A1a/A1a或Pro/A1a)与GDM发病风险相关,在等位基因模型和显性基因模型中,OR值(95%CI)分别为0.74(0.60~0.93)和0.79(0.65~0.96),P值均〈0.05。(2)不同种族人群分析:亚洲人群PPARγ2基因Pro12A1a多态性与GDM发病风险相关,OR值(95%CI)分别为0.61(0.48~0.79)(等位基因模型)和0.64(0.50~0.82)(显性基因模型),P值均〈0.01。(3)中国人群PPAR12基因Pro12A1a多态性与GDM发病风险相关,OR值(95%CI)分别为0.52(0.36~0.73)(等位基因模型)和0.55(0.39~0.80)(显性基因模型),P值均〈0.01。(4)基因分型方法的亚组分析:采用聚合酶链反应-限制性内切酶技术进行基因分型方法的文献显示PPAR月γ2基因Pro12A1a多态性与GDM发病相关,OR值(95%CI)分别为0.58(0.43~0.79)(等位基因模型)和O.62(0.45~0.85)(显性基因模型),P值均〈0.01。采用TaqMan探针法进行基因分型的文献显示PPARγ2基因Pro12A1a多态性与GDM发病风险无关,OR值(95%CI�Objective To evaluate the association between Pro12A1a polymorphism in peroxisome proliferator activated receptor γ2 (PPARγ2) gene and gestational diabetes mellitus(GDM). Methods Publications on genetic association studies of PPAR γ 2 and GDM were searched using the PubMed database, The HuGE Navigator, China National Knowledge Infrastructure (CNKI), Wanfang database and VIP Science from the inception of the databases to December 1, 2014. Two reviewers independently selected literature according to the inclusion and exclusion criteria, extracted data and assessed the quality of the data using the Newcastle-Ottawa Scale (NOS) standard. Meta-analysis was performed using RevMan 5.3 software. Results Overall, 13 eligible articles were identified, including seven in English and six in Chinese, with a total of 2 787 GDM cases and 5 408 healthy controls. Quality assessment showed that the quality of the 13 articles was all good, with NOS ≥ 5. (1) Prol2Ala polymorphism in PPAR γ2 (allele Ala or genotype Ala/Ala or Pro/Ala) was shown to be highly associated with GDM occurrence on general evaluation, with an OR(95%CI) of 0.74(0.60-0.93) in the allele model and 0.79(0.65-0.96) in the dominant genetic model (P〈0.05, respectively). (2) Pro12A1a polymorphism in PPAR γ2 was shown to be highly associated with GDM occurrence in Asians in a stratification analysis of ethnicity in the populations included in the studies, with an 0R(95%CI) of 0.61(0.48-0.79) in the allele model and 0.64(0.50-0.82) in the dominant genetic model (P〈0.01, respectively). No correlation was found between the Pro12A1a polymorphism in PPAR γ2 and GDM in the Caucasian population. (3) A meta-analysis of six Chinese studies showed that the Pro12A1a polymorphism in PPAR γ2 was associated with the risk of GDM in the Chinese population, with an 0R(95%CI) of 0.52 (0.36-0.73) in the allele model and 0.55(0.39-0.80) in the dominant genetic model (P〈0.01, respectively).
