Background/aims: Circular RNAs (circRNAs) are transcribed prevalently in the genome; however, their potential roles in multiple cardiovascular diseases, particularly preeclampsia (PE), are not yet well understood. This study investigated the expression profiles of circRNAs and explored circRNA-mediated pregnancy-associated plasma protein A (PAPP-A) expression as a potential biomarker for PE before 20 weeks of pregnancy.
Methods: A nested case-control two-phase screening/validation study was performed in pregnant women before 20 weeks of gestation (before clinical diagnosis) at Guangzhou Women and Children's Medical Center from 2012 to 2015.

Objective: To assess the features of the platelets (PLTs) of hypertensive disorders of pregnancy (HDP) and to determine whether they have a predictive value for the disorders during the preclinical stage.
Methods: This study included 461 HDPs and 827 normal pregnancies. Platelet counts were compared between the two groups by an independent samples t test; a Fisher's linear discriminant analysis and receiver operator characteristic curve were performed to analyze the diagnostic effects of the variables in developing HDP.
