摘　　要：目的探究纤溶酶原激活物抑制物-1(PAI-1)基因4G/5G多态性与行羟氯喹联合肝素治疗不明原因复发性流产(URSA)患者妊娠结局的相关性。方法选取2019年1月至2021年1月肇庆市第一人民医院收治的138例URSA患者为研究对象,检测所有受试者PAI-1基因4G/5G位点基因多态性。患者均采用羟氯喹联合肝素治疗,根据妊娠结局分为良好妊娠结局组和不良妊娠结局组。观察两组间PAI-1基因4G/5G基因位点基因型及等位基因的分布差异,并分析PAI-1基因4G/5G位点基因多态性与行羟氯喹联合肝素治疗URSA患者妊娠结局的相关性。结果138例患者中117例患者在治疗后妊娠成功,妊娠成功率为84.78%(117/138)。117例妊娠成功的患者中6例失访,失访率为5.13%(6/117)。111例患者中流产22例,低体质量儿6例,死胎、新生儿死亡各2例,不良妊娠结局发生率为28.83%(32/111)。两组职业类别、工作性质、PAI-1基因型分布比较差异有统计学意义(P<0.05或P<0.01),不良妊娠结局组大专及以上的比例低于良好妊娠结局组[37.50%(12/32)比60.76%(48/79)](P<0.05),生化妊娠史占比高于良好妊娠结局组[81.25%(26/32)比50.63%(40/79)](P<0.01)。不良妊娠结局组PAI-1基因4G等位基因频率高于良好妊娠结局组[65.63%(42/64)比37.97%(60/158)](P<0.01)。多因素Logistic回归分析结果显示,PAI-1基因型4G/4G、4G等位基因及生化妊娠史是行羟氯喹联合肝素治疗URSA患者不良妊娠结局发生的危险因素(OR=3.747,95%CI 1.470~6.024;OR=4.204,95%CI 1.672~6.736;OR=2.672,95%CI 1.269~4.076)(P<0.01)。结论PAI-1基因型4G/4G和4G等位基因与行羟氯喹联合肝素治疗URSA患者发生不良妊娠结局关系密切,是导致行羟氯喹联合肝素治疗URSA患者不良妊娠结局发生的危险因素。Objective To explore the correlation between the 4G/5G polymorphism of plasminogen activator inhibitor-1(PAI-1)gene and pregnancy outcomes in patients treated with hydroxychloroquine combined with heparin for unexplained recurrent spontaneous abortion(URSA).Methods A total of 138 patients with URSA treated in Zhaoqing First People′s Hospital from Jan.2019 to Jan.2021 were included.The 4G/5G polymorphisms of PAI-1 gene were detected in all subjects.All of the patients were treated with hydroxychloroquine combined with heparin,and were divided into a good pregnancy outcome group and a bad pregnancy outcome group according to the pregnancy outcome.The differences in the distribution of 4G/5G genotype and alleles of PAI-1 gene between the two groups were observed,and the correlation between the 4G/5G polymorphism of PAI-1 gene and pregnancy outcomes in patients treated with hydroxychloroquine combined with heparin for URSA was analyzed.Results Among the 138 patients,117 had a successful pregnancy after treatment,and the pregnancy success rate was 84.78%(117/138).Among the 117 successful pregnancies,6 cases were lost to follow-up,with a loss rate of 5.13%(6/117).Among the remaining 111 patients,22 had abortion,6 had low body weight infants,2 were stillbirths and 2 were neonatal deaths,and the incidence of adverse pregnancy outcome was 28.83%(32/111).There were statistically significant differences in occupational category,job nature and PAI-1 genotype between the two groups(P<0.05).The proportion of a college degree or above in the adverse pregnancy outcome group was lower than that in the good pregnancy outcome group[37.50%(12/32)vs 60.76%(48/79)](P<0.05),the percentage of biochemical pregnancy history was higher than that in the good pregnancy outcome group[81.25%(26/32)vs 50.63%(40/79)](P<0.01).The 4G allele frequency of the PAI-1 gene was higher in the bad pregnancy outcome group than in the good pregnancy outcome group[65.63%(42/64)vs 37.97%(60/158)](P<0.01).The results of the multivariate Logistic regression a
