Primary immune thrombocytopenia (ITP) is a bleeding disorder commonly encountered in clinical practice. The International Working Group (IWG) on ITP has published several landmark papers on terminology, definitions, outcome criteria, bleeding assessment, diagnosis, and management of ITP. The Chinese consensus reports for diagnosis and management of adult ITP have been updated to the 4th edition. Based on current consensus positions and new emerging clinical evidence, the thrombosis and hemostasis group of the Chinese Society of Hematology issued Chinese guidelines for management of adult ITP, which aim to provide evidence-based recommendations for clinical decision making.

Cardiomyocyte apoptosis is a common pathological injury in association with acute myocardial infarction (AMI). In the current study, the relationship between Ras-association domain family 1 (RASSF1) and cardiomyocyte apoptosis was investigated. RASSF1 was significantly over expressed in infarcted myocardial tissues as well as in cardiomyocytes induced by hypoxia. Inhibition of RASSF1 expression alleviated cardiomyocytes apoptosis induced by hypoxia in vitro and reduced cardiomyocytes apoptosis after AMI in vivo.RASSF1 expression was directly modulated by miR-125b, which was further confirmed by luciferase reporter assay. The current study verified that the miR-125b/RASSF1 axis was involved in cardiomyocytes apoptosis. To sum up, these results suggest that RASSF1 downregulation alleviated infarction-induced cardiomyocytes apoptosis and was regulated by miR-125b.
