| Abstract: |
| 目的 <\b>探讨口服避孕药(OC)暴露和血管紧张素原(AGT)基因多态及其联合作用与中国女性脑卒中发病风险的关联.方法 <\b>在“女性避孕药和宫内节育器使用队列”随访的基础上前瞻性收集确诊的脑卒中新发病例,采用病例对照研究方法(按年龄和地区匹配健康对照和医院对照),应用实时荧光定量PCR(Taqman)检测其基因型.结果 <\b>(1)OC轻度升高出血型脑卒中发病风险(OR=1.83,95％CI:1.25～ 2.66).(2)A-6G的AG/GG基因型降低脑卒中发病风险(OR=0.78,95％CI:0.61 ～ 0.99)；Cl1535A的CA/AA基因型使梗塞型脑卒中风险略有降低(OR=0.62,95％CI:0.45 ～ 0.85),AA基因型则使出血型脑卒中的发病风险升高(OR=2.57,95％CI:1.03～6.42).(3)OC和AGT基因的联合作用使得出血型脑卒中的发病风险略有升高.结论 <\b>AGT基因多态性与中国女性脑卒中的发病有关,OC与AGT基因多态性之间的联合作用可能升高出血型脑卒中的发病风险. |

| Objective <\b>To evaluate the associations of oral contraceptives (OC) exposure,angiotensinogen (AGT) gene polymorphism and joint effects on the risk of stroke in Chinese women.Methods <\b>On the basis of a prospective female cohort of contraceptive use,the first-ever-developed (FED) stroke cases,as well as,two sets of age-(± 3 years) and region-matched controls (including neighborhoods and hospitalized patients) were recruited.Between 1 July 2000 and 30 June 2009,a total of 453 FED stroke cases and 919 controls were recruited.Genotyping for polymorphisms of AGT gene was detected by Taqman method.Results <\b>(1) The risk of stroke gradually increased with the cumulative time of OC use in women (P＜0.0001).Compared with the non-users,the risk of hemorrhagic stroke slightly increased among those with OC use (OR=1.83,95％CI:1.25-2.66).(2)Women with AG/GG genotypes of A-6G locus or CA/AA genotypes of Cl1535A locus indicated that there was a slightly reduced risk of stroke (OR=0.78,95％ CI:0.61-0.99; OR=0.73,95％ CI:0.56-0.95).(3) Women with AA genotypes of A-20C locus and AG/GG genotypes of A-6G,when incorporated with CA/AA genotypes of Cl1535A locus with OC,it could increase the risk of hemorrhagic stroke(OR=1.99,95％CI:1.34-2.97; OR=1.84,95％CI:1.15-2.94; OR=1.73,95％CI:1.06-2.85).Conclusion <\b>The AGT gene polymorphisms showed that they did have an impact on the risk of stroke.And the joint effect between women using OC and AGT gene polymorphisms could slightly increase the risk of stroke. |
