Research progress in hematopoietic stem cell transplantation for bone marrow acute radiation syndrome / 中国辐射卫生

ABSTRACT

As is known, the nuclear accident resulting from the explosion of a nuclear weapon or the release of nuclear material could cause acute radiation syndrome within a short time. The study had found that the dose of > 0.7 Gy radiation on human body can result in persistent myelosuppression, a kind of acute radiation syndrome, leading to pancytopenia, bleeding, infection and other injuries. Several evidences also have shown that hematopoietic stem cell is conducive to repair hematopoietic injury in bone marrow, improve hematopoietic microenvironment and promote hematopoietic reconstruction. Therefore, hematopoietic stem cell transplantation is widely considered as the main treatment of the bone marrow acute radiation syndrome. However, before a surgery of hematopoietic stem cell transplantation, it still needs more research on donor selection, formulation of preconditioning and prevention of complications such as graft-versus-host disease. This paper mainly summarizes the application and research progress of hematopoietic stem cell transplantation in treating radiation injury.
