研究目的:

先兆子痫、胎儿宫内生长迟缓、早产、自然流产、胎盘早剥等一系列妊娠并发症被统称为大产科综合征。其病理生理基础是胎盘血管生产异常,特别是子宫螺旋动脉重铸不良。合体滋养细胞在胚胎种植第8-10天侵入内膜间质的毛细血管,细胞滋养细胞在第12天开始对子宫螺旋动脉的进行重铸改造。目前,合体滋养细胞合成的HCG被用于评价早期胚胎发育情况,而细胞滋养细胞合成的PlGF及sFlt1则用于中晚期妊娠大产科综合征的监测。我们前期检测100例经辅助生殖技术受孕患者胚胎移植第12天的外周血HCG,PlGF和sFlt1水平并随访其妊娠结局,数据显示三者与妊娠丢失具有相关性。因此我们推测其具有联合预测大产科综合征的价值并设计该临床试验以检测胚胎移植第12天外周血HCG,PlGF和sFlt1水平,评价胚胎着床期合体滋养细胞和细胞滋养细胞的功能,评估子宫螺旋动脉重铸情况,统计分析以获得预测大产科综合征疾病的风险值,为更早的预测,监测,防治大产科综合征提供参考。  

Objectives of Study:

Great obstetrical disorders are a spectrum of complications of pregnancy, including preeclampsia, intrauterine growth restriction, preterm labor, spontaneous abortion and abruption placentae. Great obstetrical disorders are associated with defective deep placentation and impaired spiral arteries remodeling. On the 8-10th day of embryo implantation, syncytotrophoblast cells begin to intrude into endometrium and migrate to capillary. And on the 12th day, cytotrophoblast cells remodel spiral arteries. HCG is secreted by syncytotrophoblast cell. In clinical practice, HCG is used to evaluate the conceptus growth in the first trimester. PlGF and sFlt1 are synthesized in cytotrophoblast cells, which are employed to predict the preeclampsia during the second and third trimester. In our previous study, we measured the HCG, PlGF and sFlt1 levels on the 12th day post-embryo-transfer in 100 participants and followed their pregnancy outcomes. Primary statistical analysis showed a relationship between the three biomarker levels and pregnancy loss. Serum HCG, PlGF and sFlt1 levels reflect the functions of syntrophoblast cell and cytotrophoblast cell respectively. And the three biomolecules can be measured as early as on the 12th post-embryo-transfer. We suspect them might be able to predict the great obstetrical syndromes. We design the clinical trial and aim to find the predictive value of HCG, PlGF and sFlt1 levels for great obstetrical syndromes and provide a valuable reference for early detection and early treatment of great obstetrical syndromes.
