母胎界面维生素D受体表达与复发性自然流产相关及可能的机制

目的 探讨母胎界面维生素D受体(VDR)表达与复发性自然流产及胎盘激素的关系.方法 2014年7月至2014年9月在西安交通大学第一附属医院妇产科门诊收集复发性流产患者和正常早孕妇女绒毛和蜕膜组织,采用荧光实时定量聚合酶链式反应(FQ-PCR)检测两组绒毛组织和蜕膜组织中VDR及绒毛膜促性腺激素受体、雌激素受体和孕激素受体mRNA的含量,比较两组表达的差异.结果 复发性流产组绒毛组织中VDR、绒毛膜促性腺激素受体、雌激素受体mRNA相对水平低于对照组(t值分别为4.86、6.16、2.39,均P<0.05);绒毛膜促性腺激素受体和雌激素受体mRNA的表达水平与VDR表达水平明显正相关(F=10.21,P=0.01;F=14.52,P=0.00).复发性流产组蜕膜组织中VDR、绒毛膜促性腺激素受体、雌激素受体mRNA相对水平也低于对照组(t值分别为5.28、2.34、2.60,均P<0.05).结论 母胎界面VDR mRNA表达水平与早期自然流产相关,绒毛组织绒毛膜促性腺激素受体和雌激素受体mRNA的表达水平与VDR表达水平有一定的相关性.但是VDR导致自然流产的机制仍需进一步研究.

Relationship between vitamin D receptor expression on fetal-maternal interface and recurrent miscarriage and possible mechanism

Objective To explore the relationship between vitamin D receptor (VDR) expression on fetal-maternal interface and recurrent miscarriage (RM) and placental hormone.Methods Villous and decidual tissue samples from patients with RM and those at normal early pregnancy were collected outpatient department of obstetrics and gynecology in the First Affiliated Hospital of Xi'an Jiaotong University from July to September in 2014.VDR, human chorionic gonadotropin receptor (HCGR), estrogen receptor (ER) and progesterone receptor (PR) mRNA levels in two groups were detected by fluorescence real-time quantitative polymerase chain reaction (FQ-PCR) and expression difference was compared
