层粘连蛋白及其受体在葡萄胎中表达与预后的相关研究

目的：探讨层粘连蛋白（Laminin,LN）和受体（Laminin Receptor,LN-R）的表达在葡萄胎预后中的意义.方法：应用免疫组化方法对41例葡萄胎组织（经随访13例发生恶变）和20例正常早孕绒毛组织中LN及LN-R进行检测.结果：LN在正常绒毛、葡萄胎未恶变组和恶变组中的强表达率分别为,90.0%（18/20）、71.4%（20/28）、38.5%（5/13）;LN-R分别为70.0%（14/20）、71.4%（20/28）、84.6%（11/13）.LN表达葡萄胎预后恶变组显著高于其他两组.结论：LN和LN-R在葡萄胎中的表达可能在葡萄胎恶变过程中起重要作用,有望作为判断葡萄胎预后的参考指标之一.

Research on expression of laminin and laminin receptor in hydatidiform mole and prognosis factors

Objective: To investigate the significance of laminin(LN) and laminin receptor(LN-R) in the proceeding and prognosis of hydatidiform mole.Methods: Immunohistochemical SP staining was used to detect the expression of LN and LN-R in 41 hydatidiform mole cases(13 cases were learned to have turned malignant by following up).20 cases of normal early gestational chorion were detected as control.Results: The strong positive rates of LN and LN-R in normal chorion,hydatidiform mole un-malignant group and malignant group were respectively 90.0%(18/20),71.4%(20/28),38.5%(5/13),and 70.0%(14/20),71.4%(20/28),84.6%(11/13).The strong expression of LN had a significant difference between malignant group and the other 2 groups(P<0.05).Conclusion: LN and LN-R may play an important role in malignant proceeding of hydatidiform mole.Detection of LN and LN-R may be of great value in assessing the prognosis of moles.
