Methods Twenty-one patients with malignant hematological diseases received URD-HSCT. There were 19 cases of peripheral blood hematopoietic stem cell transplantation, one case of bone marrow transplantation, and one case of umbilical cord blood transplantation. There were 8 cases of HLA matched and 13 cases of HLA mismatched transplantation. The median of infused donor MNC was 9.078×108/kg, and the median of CD34 positive cells was 4.62×106/kg. Ten patients were treated with BuCy conditioning regimen, nine patients with modified BuCy2 conditioning regimen, one with non-myeloablative BuCy+fludarabine conditioning regimen, and another one was treated with TBI+VP-16+CTX+CCNU conditioning regimen. Only one case received short-term MTX, cyclosporin A and ATG regimen for prevention of graft-versus-host disease (GVHD). The GVHD prevention regimens of the other patients were based on short-term MTX, cyclosporin A, ATG and mycophenolate mofetil regimen. The hematopoietic reconstitution, complications and prognosis were observed. Results One patient died of intracranial hemorrhage, and hematopoietic reconstitution was achieved in the other 20 patients. The median time for hematopoietic reconstitution shortened by one day in large-dose group compared with that in low-dose group. Adverse reactions included high fever, shivering, gastrointestinal tract adverse reaction, liver injury, oral
