研究目的:

通过多中心研究建立前瞻性、有国际影响力、开放共享的双胎妊娠母子队列和生物样本库,构建母胎妊娠期生理参数包括代谢内分泌参数,母体体重增重,胎儿生长发育及血流动力学指标,药物跨胎盘转运的数据库;输血综合征、双胎贫血红细胞增多序列征、选择性胎儿宫内生长受限及双胎反向动脉灌注综合征)的预测及预防方法研究,包括双胎早产的预测及预防,子痫前期的预防,双胎特殊并发症的临床评估,构建精准的临床预测模型及干预手段,开展多中心临床研究。  

Objectives of Study:

Through multi-center research, a prospective, internationally influential, open and shared pregnancy cohort and biobank of twin pregnancy were established, and a database of physiological parameters of maternal and fetal pregnancy including metabolic endocrine parameters, maternal weight gain, fetal growth and development and hemodynamic indicators, and drug transplacental transport was constructed. On the basis of the twin mother-infant cohort, the prediction and prevention methods of serious pregnancy complications (preterm birth, preeclampsia and twin-specific complications including twin transfusion syndrome, twin anemia erythrocytosis sequence signs, selective fetal intrauterine growth restriction and twin reverse arterial perfusion syndrome) were studied, including the prediction and prevention of preterm birth of twins, the prevention of preeclampsia, and the clinical evaluation of special complications of twins, and accurate clinical prediction models and intervention methods were constructed, and multi-center clinical studies were carried out.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

数据类型:CRF;根据设计的病例报告表收集受试者相关信息资料。数据收集在本研究主要负责人监督下进行,且对报告数据的准确性、完整性、及时性负责;所有数据均获得于中南大学湘雅医院资料。临床数据将建立数据库报关,数据库有密码保护,且建立时设立逻辑校对程序。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data type: CRF; information about the subjects was collected according to the designed case report form. Data collection was carried out under the supervision of the principal investigator, who was responsible for the accuracy, completeness and timeliness of the reported data; all data were obtained from Xiangya Hospital of Central South University. The clinical data will be reported in a password-protected database with a logical checking procedure.
