Aplastic anemia in children can be cured. Aplastic anemia is a disease in which the hematopoietic stem cells and bone marrow microenvironment are damaged by different causes, leading to bone marrow hematopoietic failure, for example, in the clinic, children with aplastic anemia receive their own umbilical cord blood left at birth and achieve cure after doing umbilical cord blood transplantation, so children with aplastic anemia can be cured. Aplastic anemia is divided into chronic aplastic anemia and heavy aplastic anemia. For chronic aplastic anemia, the main focus is to promote hematopoietic treatment, giving immunosuppressant and hematopoietic factor treatment. For heavy aplastic anemia, ATG and allogeneic bone marrow transplantation are the main treatments, and the treatment efficiency of ATG and bone marrow transplantation can reach about 60%.
