AA is a group of diseases characterized by hematopoietic stem/progenitor cell damage, oerioheral blood cvtooenia, andclinical manifestations including anemia, bleeding and infection, which eventually lead to bone marrow failure. The incidence rate of AA in China is 7.4/10^6, higher than that in Western countries, among which the morbidity of acute AA and chronic AA （CAA） is 1.4/10^6 and 6.0/10^6, respectively.展开更多
