摘  要:目的探讨过氧化物酶体增殖物激活受体(PPAR)与高甘油三酯血症的关联及基因一基因的交互作用。方法研究对象来自“江苏省多代谢异常和代谢综合征综合防治研究”队列人群。于2009年对随访得到的4083名对象采用单纯随机抽样的方法抽取了820名研究对象,于基线和随访时采集空腹8h静脉血11ml。对研究对象的基线血标本进行PPARα、PPARδ、PPARγ的基因多态性检测,并对随访得到的血标本进行血脂检测。使用logistic回归模型分析不同SNP与高甘油三酯血症的关联,并采用广义多因子降维法(GMDR)模型分析基因一基因的交互作用。结果调查对象中非高甘油三酯血症者474名,高甘油三酯血症者患者346例。rs1800206位点的LL、LV、VV的基因型频数在高甘油三酯血症组分别为211(61.0%)、132(38.2%)、3(0.9%),在非高甘油三酯血症组分别为411(86.7%)、59(12.4%)、4(0.8%)(χ2=74.18,P〈0.01),V等位基因频数在高甘油三酯血症组和非高甘油三酯血症组分别为138(19.9%)和67(7.1%)(χ2=60.62,P〈0.01);rs2016520位点的TT、TC、CC的基因型频数在高甘油三酯血症组分别为177(51.2%)、154(44.5%)、15(4.3%),在非高甘油三酯血症组分别为211(44.5%)、212(44.7%)、51(10.8%)(χ2=12.12,P〈0.01),C等位基因频数在高甘油三酯血症组和非高甘油三酯血症组分别为184(26.6%)和314(33.1%)(χ2=8.07,P〈0.01);rs3856806位点的CC、CT、TT的基因型频数在高甘油三酯血症组分别为149(43.1%)、156(45.1%)、41(11.8%),在非高甘油三酯血症组分别为269(56.8%)、170(35.9%)、35(7.4%)(χ2=15.93,P〈0.01),T等位基因频数在高甘油三酯血症组和非高甘油三酯血症组分别为238(34.4%)和240(25.3%Objective To investigate the association of ten SNP at peroxisome proliferator-activatedreceptors (PPARα, δ, γ) with hypertriglyceridemia and the gene-gene interaction. Methods Participants were recruited from the Prevention of MetS and Multi-metabolic Disorders in Jiangsu province of China Study (PMMJS). A total of 820 subjects were selected from the 4083 participants who had received follow-up examination, by using simple random sampling. Participants in baseline and follow-up study surveys were both collected blood samples 11 ml in the morning after at least 8 hours of fasting. Blood samples which collected at the baseline were subjected to PPARα, PPARδ and PPARγ genotype analyses. Blood samples which collected at the follow-up were used to measure serum triglyceride levels. The logistic regression model was used to analyze the association between different SNP and hypertriglyceridemia, and the generalized multifactor dimensionality reduction (GMDR) was applied to explore the gene-gene interaction. Results The samples included 474 in the non-hypertriglyceridemia group and 346 in the hypertriglyceridemia group. The genotype frequencies of rs1800206 in the hypertriglyceridemia group were 211(61.0% ) for LL, 132(38.2% ) for LV and 3 (0. 9% ) for VV, and in the non-hypertriglyceridemia group were 411(86.7%) for LL, 59(12.4%) for LV and4(0.8%) forVV (χ2 =74.18,P〈0.01) . V allele frequencies of rs1800206 in the hypertriglyeeridemia group was 138 ( 19. 9% ), and in the non-hypertriglyceridemia group was 67 ( 7. 1% ) ( χ2 = 60. 62, P 〈 0. 01 ) . The genotype frequencies of rs2016520 in the hypertriglyceridemia group were 177 (51.2%) for TT, 154 (44. 5% ) for TC and 15 (4. 3% ) for CC, and in the non-hypertriglyceridemia group were 211 (44. 5% ) for TT, 212(44. 7% ) for TC and 51(10.8%) for CC (χ2 = 15.93, P 〈 0.01) .C allele frequencies of rs2016520 in the hypertriglyceridemia group was 184( 26. 6% ), and in the non-hype
