1、子宫内膜异位症组织SRC-KER与PR表达及意义作者:欧阳江华,郭新华,高萍,夏玉芳单位:青岛大学医学院附属医院妇科,山东青岛【摘要】目的探讨类固醇受体辅活化因子T(SRC-1)、此瞰素受体(ER)、孕激素受体(PR)在卵巢子宫内膜异位症(EMs)病人在位和异位内膜中的表达及其意义。方法采用免疫组织化学SABC法,对45例EMs病人在位和异位内膜及42例对照组正常内膜屮的SRC-l、ER、PR进行染色,并利用图像分析系统测定其灰度值。结果SRC-1在在位内膜屮的表达显著高于异位内膜和对照组内膜,差异有显著性(—8
2、.210、7.260,P<0.05);SRC-1在在位内膜增殖期和分泌期中的表达强度均显著高于相应期别的异位内膜及对照组内膜(258.641、7.650,q=4.162〜12.052,P<0.01)oER、PR在异位内膜增殖期的表达均显著低于同期对照组及在位内膜组(265.08、59.42,q=11.661~14.500,P<0.01);对照组内膜中SRC-1、ER、PR在增殖期表达显著高于分泌期(t=5.909〜10.183,P<0.01)。SRCT、ER、PR在EMs的表达与rAFS分
3、期差异均无显著性(t二1.352〜1.838,P>O.05)o在位内膜中SRC-1与ER的表达强度呈正相关(r=0.779,P<0.05)o结论SRC-1、ER、PR在在位和异位内膜中的表达异常可能与EMs的发生发展有关。【关键词】类固醇受体辅活化因子T;受体,雌激素;受体,孕激素;子宫内膜异位症;免疫组织化学EXPRESSIONSOFSRC-1,ERANDPRANDTHEIRSIGNIFICANCEOUYANGJIANG-HUA,GUOXIN-HUA,GAOPING,etalDepartmentof
