摘要
Ionizing radiation existing in heavy ion cancer therapy,nuclear device,spaceflight or terror attack is one of the major threats to human health and public security.During the past year,the main research task of Department of Space Radiobiology focus on the assessment,protection and underlying mechanisims of ionizing radiation both in vitro and in vivo.Noninvasive biomarkers that can rapidly assess the exposure degree in the early stage of ionizing event are urgently needed for optimal medical treatments when an unexpected accident happens.Serum microRNAs(miRNAs)are ideal biomarkers because they are stable in responding to the changes of environments,conservative in different species and easy for collection.
