摘要: 目的: 探讨雌激素受体(ER)基因多态性在新疆维吾尔族(维族)妇女中的分布及其与子宫内膜异位症(内异症)的遗传易感性的关系。 方法: 应用 PCRRFLP技术,检测107例维吾尔族健康妇女(对照组)及65例经腹腔镜或手术证实为内异症患者(内异症组)的ER基因XbaⅠ和PvuⅡ酶切多态性。两组检测对象均为世居新疆的维吾尔族妇女。 结果: ER基因型频率分布符合Hareyweinberg平衡定律。ER等位基因X、x和P、p在内异症组与对照组频率分别为0.223、0.777、0.231、0.769和0.168、0.832、0.341、0.659。ER基因PvuⅡ酶切多态性基因型频率、等位基因频率在内异症组与对照组间的差异有统计学意义(P<0.05 );两组XbaI酶切多态性基因型频率、等位基因频率的差异无统计学意义(P>0.05); ER基因XbaⅠ和PvuⅡ组合基因型分布在组间、组内分布的差异无统计学意义(P>0.05)。 结论: ER基因XbaⅠ酶切多态性与维族妇女内异症发病无关,而PvuⅡ酶切多态性与内异症发病有关。PvuⅡ基因多态性可能是维族妇女子宫内膜异位症发病的危险因素之一。关键词: 维吾尔族;受体, 雌激素;多态现象(遗传学);子宫内膜异位症

Abstract: Objective: To study the distribution of estrogen receptor (ER) gene polymorphisms of the Uygurs in Xinjiang and the association of the polymorphisms with endometriosis of the Uygurs. Methods: This study involved the Uygurs 172(65 cases and 107 controls). XbaⅠ and PvuⅡ polymorphisms of ER gene were detected by polymerase chain reactionrestriction fragment length polymorphism (PCRRFLP) in genome DNA.The data were analyzed by χ2 test. Results: ER allelic frequencies of X, x and P, p alleles were 0.223 ......
