摘要
目的在长期低剂量激素替代疗法（HRT）下,观察绝经后妇女外周血中内吗啡肽1（EM-1）和内吗啡肽2（EM-2）的变化,并对内吗啡呔与雌激素进行相关性分析。方法研究对象系北京协和医院已绝经女职工共169人,全员根据年龄共分为4组,包括50~59岁,60~64岁,65~69岁,70岁以上,每年龄段内均包括HRT组和对照组。用酶联免疫反应测试仪测定受试者血浆性激素水平,用放射免疫法检测血浆内EM-1和EM-2的含量。结果各年龄段HRT治疗组E2的水平均显著高于对照组（P〈0.05）;各年龄段HRT治疗组EM-1和EM-2的水平均低于对照组,且全体受试者血浆雌激素E2的水平与EM-1具有Pearson’s相关性。结论首次观察了在长期低剂量HRT疗法下绝经后妇女外周血中内吗啡肽1和2的变化,该结果对如何保护绝经后妇女的脑认知具有一定的临床意义。
Objective To investigate the levels of EM-1 and EM-2 in peripheral blood with long-term low dose HRT therapy and analyze the relationship between endomorphins and estradiol. Methods 169 female medical staff in Peking Union Medical College Hospital were included in our study. Based on age, participants were divided into 4 groups, including 50~59, 60~64, 65~69 and over 70 years old, HRT group and control group were included in each age group. Plasma hormones including estradiol（E2）, progesterone（P） and testosterone（T） were detected by using Bio-RAD 550 Model ELISA（enzyme-linked immunosorbent assay） device, and levels of EM-1 and EM-2 were examined by radioimmunoassay methods. Results Compared to control group at each age, plasma estrodiol（E2） levels obviously increased in HRT groups（P 0.05）. The levels of EM-1 and EM-2 in HRT group of each age decreased compared to control group, meanwhile, pearson correlation analysis showed that the level of endomorphin-1（EM-1） on all subjects was correlated with their individual estradiol（P 0.01）. Conclusion This is the fi rst observation of the relationship between endomorphins and estradiol in a long-term low-dose HRT therapy, which providing clinical signifi cance of protecting brain cognition in postmenpausal women.
