[Abstract] Objective:To investigate the impact of the graft content including mononuclear cells(MNC),CD34 cells and T⁃lymphocyte
subsets on post⁃transplant survival. Methods:A retrospective analysis of 121 patients with hematologic malignant diseases undergoing
allogeneic hematopoietic stem cell transplantation(allo⁃HSCT)was performed to investigate the effects of the doses of MNC,CD34 +
+
+
+
cells,CD3 T cells,CD4 T cells,CD8 T cells and regulatory T(Treg)cells in the grafts on hematopoietic reconstitution and survival.
Results:Neutrophils were successfully engrafted in 120 patients,and patients with high doses of CD34 cells(≥6.90×10 /kg)(P < 0.001),

CD3 T cells(≥6.24×10 /kg)(P=0.042)and CD8 T cells(≥1.05×10 /kg)(P=0.021)had more rapid engraftment of neutrophils. Platelets

were successfully engrafted in 119 cases,and high dose CD34 cells were associated with faster platelet reconstruction(P=0.001).
Acute graft⁃versus⁃host disease(aGVHD)occurred in 53(43.8%)patients and 28 patients had chronic graft⁃versus⁃host disease
(cGVHD). One and 3⁃year overall survival(OS)rates were 83.5% and 68.0%,and one and 3⁃year progression⁃free survival(PFS)

rates were 75.0% and 64.4%. In univariate analysis,the patients with high MNC dose(≥9.79×10 /kg),high CD3 T cells dose and

+
+
CD4 /CD8 T cells <3.57 had better OS and the high MNC group had better PFS(P=0.061). Multivariate analysis showed that the CD4 /

CD8 T⁃cell < 3.57 group had better OS(HR=0.288,95%CI:0.084~0.988,P=0.048). One and 3⁃year cumulative incidence of relapse
