To investigate the changes of peripheral blood marrow-derived suppressor cell level after chemotherapy induction remission by regimen consisting of vincristine, daunorubicin, L-asparaginase and prednisone (VDLP) and to analyze their relationship with immume system in B-ALL children.Thirty B-ALL children after induction remission by VDLP regimen from August 2015 to August 2016 were selected as B-ALL group and 30 normal healthy children were selected as control group. The peripheral blood in 2 groups was collected and detected by flow cytometry, then the ratios of CD30+ cells and CD33+ HLA-DR- marrow-derived suppressor cells, CD14+CD33+HLA-DR- marrow-derived suppressor cells and CD15+CD33+HLA-DR- marrow-derived suppressor cells were calculated, and their changes after induction remission by VDLP regimen and the relationship with immune system were analyzed.After treatment the ratio of CD33+ cells in peripheral blood of B-ALL group and control group was not significantly different (P> 0.05), moreover, the ratio of CD33+ cells in B-ALL group was significantly higher than that before treatment (P0.05).The ratios of marrow-derived suppressor cells in peripheral blood of B-ALL children in complete remission after treatment with VDLP regimen are higher than those before treatment, but are significantly lower than normal value, which may be related with non-complese recovery of immune system in B-ALL children after treatment.
