摘　　要：目的探讨血清微小RNA-200a(miR-200a)、微小RNA-152(miR-152)在妊娠滋养细胞肿瘤(GTN)预后中的作用。方法选取100例GTN化疗患者为观察组,根据化疗疗效将患者分为预后良好组80例和预后不良组20例;选取同期体检健康女性103例为对照组。采用实时荧光定量PCR法检测血清miR-200a、miR-152表达水平。结果观察组血清miR-200a表达水平高于对照组,miR-152表达水平低于对照组(P<0.05)。随化疗时间延长,预后良好组与预后不良组血清miR-200a表达水平依次降低,miR-152表达水平依次升高(P<0.05)。预后不良组化疗前后血清miR-200a表达水平高于预后良好组,miR-152表达水平低于预后良好组(P<0.05)。预后良好组与预后不良组国际妇产科联盟(FIGO)预后评分、化疗前血HCG水平比较,差异有统计学意义(P<0.05)。化疗前血清miR-200a、miR-152表达水平单独及联合预测GTN化疗患者预后不良的AUC分别为0.793、0.844、0.887。miR-200a、miR-152、FIGO预后评分≥7分与GTN化疗患者预后不良有关(P<0.05)。结论化疗前高表达miR-200a,低表达miR-152可能与GTN化疗患者预后不良有关,可为化疗预后评估提供参考。Objective This study mainly explores the role of serum microRNA-200a(miR-200a)and microRNA-152(miR-152)in gestational trophoblastic tumors(GTN)prognosis.Methods One-hundred GTN chemotherapy patients who treated in our hospital were collected as the observation group,according to the efficacy of chemotherapy,patients were divided into the good prognosis group(80 cases)and the poor prognosis group(20 cases);103 healthy women who underwent physical examination were collected as the control group.Real-time fluorescence quantitative PCR method was applied to detect the expression levels of miR-200a and miR-152 in serum.Results The serum miR-200a expression level in the observation group was higher than that in the control group,while the miR-152 expression level was lower than that in the control group(P<0.05).With the prolongation of chemotherapy time,the expression level of miR-200a in the serum of the good prognosis group and the poor prognosis group decreased sequentially,while the expression level of miR-152 increased sequentially(P<0.05).The expression level of miR-200a in the serum of the poor prognosis group before and after chemotherapy were higher than that of the good prognosis group,while the expression level of miR-152 was lower than that of the good prognosis group(P<0.05).There was a statistically significant difference in the International Federation of Obstetrics and Gynecology(FIGO)prognosis score and pre chemotherapy blood HCG levels between the group with good prognosis and the group with poor prognosis(P<0.05).The AUC of predicting poor prognosis in GTN chemotherapy patients with serum miR-200a and miR-152 expression levels before chemotherapy alone and in combination were 0.793,0.844,and 0.887,respectively.MiR-200a,miR-152,and FIGO prognosis scores≥7 are associated with poor prognosis in GTN chemotherapy patients(P<0.05).Conclusion High expression of miR-200a and low expression of miR-152 before chemotherapy may be associated with poor prognosis in GTN chemotherapy patients,which can provide re
