摘    要:目的探讨白血病抑制因子(LIF)在正常早孕、稽留流产蜕膜绒毛组织中的表达,及其与稽留流产发生的关系。方法采用免疫组化技术-链霉菌抗生物素蛋白-过氧化酶连接(SP)法对白血病抑制因子(UF)在2组妇女绒毛蜕膜组织中的表达进行组织学定位和表达强弱度分析。通过病理图像分析仪对图片进行观察,并运用所附分析系统软件测量各组平均光密度值(IOD)。采用放射免疫法检测正常早孕妇女(正常早孕组,20例)、稽留流产患者(稽留流产组,25例)血清人绒毛膜促性腺激素(β—hCG)及孕酮(P)水平。结果(1)孕酮及hCG水平在2组孕妇间的比较:正常早孕组孕妇血清中孕酮、hCG水平分别为(37.5±15.2)ng/mL、(9005,8±2134.9)mIU/L,稽留流产组孕妇分别为(19.1±11.6)ng/mL、(3120.3±1213.2)mIU/L,两组孕妇血清孕酮、hCC水平比较,有显著性(P〈0.01);(2)LIF平均相对含量在2组孕妇蜕膜、绒毛组织中的比较:正常早孕组孕妇分别为0.38±0.15,0.36±0.11;稽留流产组孕妇分别为0.20±0.17,0.18±0.13。正常早孕组与稽留流产组比较,差异有显著性(P〈0.05)。结论LIF在稽留流产蜕膜绒毛组织中的表达量降低,可能是导致hCG及孕酮分泌下降,最终造成稽留流产的原因之一。

Abstract:Objective: To study the expression of leukemia inhibitory factor (LIF) in the decidua of normal early pregnancy and missed abortion, and its relationship with missed abortion. Methods. Testing the level of β- hCG and progesterone of normal pregnancy women (20 cases) and patients with missed abortion (25 cases) by radioimmunoassay. Results : ( 1 ) Serum levels of progesterone and hCG are: (37.5 ± 15.2) ng/mL, (9005.8 ±2134. 9) mIU/L in normal early pregnancy; (19. 1 ± 11.6) ng/mL, (3120. 3 ± 1213.2) mIU/L in missed abortion respectively. There was a significant difference in the levels of progesterone and hCG between the two groups ( P 〈0. 05) . (2) The average relative contents of LIF are: 0. 38 ±0. 15, 0. 36 ±0. 11 in normal early pregnancy group; 0. 20 ± 0. 17, 0. 18 ± 0. 13 in missed abortion group respectively. There was a significant difference in the average relative contents of LIF between the two groups ( P 〈 0. 05 ) . Conclusion: The reduction of LIF expression in the decidua of missed abortion may decrease the secretion of hCG and progesterone and cause missed abortion.
Keywords:Pregnancy first trimester  Missed Abortion  Decidua  Chorion  Leukemia inhibitory factor(LIF)
