胎盘早剥孕妇血浆中Corin水平变化及其临床意义
首发时间:2021-09-18
摘要:目的:ELISA检测孕中期及分娩后胎盘早剥孕妇血浆中可溶性Corin水平,探讨Corin在胎盘早剥疾病发生与发展进程中的作用。方法:收集在南京医科大学附属苏州医院(苏州市立医院)分娩的正常妊娠、子痫前期及胎盘早剥孕妇外周血各40例,以及三组孕妇对应的孕16-18周产检血清。ELISA检测三组孕妇血浆中可溶性Corin及其底物NT-proANP水平,并根据年龄、孕周、产次、疾病严重程度、有无高血压以及是否伴有子痫前期分组,统计分析血浆中可溶性Corin水平与各组的相关性。提取三组孕妇外周血基因组DNA,进行CORIN基因外显子测序,筛选基因变异体。结论:在孕中期与孕晚期,胎盘早剥与子痫前期孕妇血浆中可溶性Corin水平均显著高于正常孕妇,可溶性NT-proANP水平均显著低于正常孕妇。血浆中可溶性Corin水平与胎盘剥离程度、是否伴有高血压/子痫前期正相关。并在1例胎盘早剥孕妇中发现CORIN基因变异体c.102-103 insA。

Alterative plasma Corin in placental abruption patients and its clinical significance
Abstract:Objective: Detect plasma/serum soluble Corin in second trimester and post-delivery patients with placental abruption by ELISA. To investigate the role of Corin in the occurrence and development of placental abruption. Methods: Blood samples were collected from 40 normal pregnant women, 40 pregnant women with preeclampsia or placental abruption in Affiliated Suzhou Hospital of Nanjing Medical University. Detect serum soluble Corin and NT-proANP in second trimester and post-delivery women by ELISA. Study the correlation between plasma Corin levels and area of placental abruption or with/without hypertension or with/without preeclampsia in placental abruption. CORIN gene sequencing to screen variants C. 102-103 insA, R539C, K317E and S472G. Results: In the second and third trimester, plasma/serum soluble Corin levels in placental abruption or preeclampsia patients were significantly higher than those in normal pregnant women, inversely, soluble NT-proANP levels were significantly lower. Plasma/serum soluble Corin levels were positively correlated with the area of placental detachment and the presence of hypertension/preeclampsia. The CORIN gene variant C.102-103 insA was found in only one pregnant woman with placental abruption. Conclusion: Corin plays an extremely important role in the occurrence and development of placental abruption.
