目的 探讨儿童AL的治疗方法.方法 采用Ficoll-Hypaque法分离AL患儿 MNC,将其分为4组.对照组:以含10%FCS的RPMI1640培养液培养;实验1组:单用 MDP;实验2组:rhGM-CSF+rhIL-4+rhTNF-α;实验3组:rhGM-CSF+rhIL-4+rhTNF-α+MDP.观察每日细胞生长情况及细胞形态,培养8d后计数各组细胞数量并应用流式细胞仪检测各组细胞免疫表型.结果 对照组培养3 d,细胞大量死亡,数量明显减少;而实验各组在培养第2-8天均出现细胞形态的变化;实验各组细胞数及HLA-DR、CD1a、CD83细胞比例均高于对照组,以实验3组最高(P<0.05).结论 MDP对AL患儿骨髓DC有扩增作用并促其成熟,与细胞因子联合作用更强.
Objective To explore the treatment methods for children with AL.Methods The Ficoll Hypaque method was used to isolate MNCs from AL patients,who were divided into four groups.Control group:cultured in RPMI1640 medium containing 10%FCS;Experiment 1 group:using MDP alone;Ex-periment 2 group:rhGM-CSF+rhIL-4+rhTNF-α;Experiment 3 group:rhGM-CSF+rhIL-4+rhTNF-α+MDP.Observe daily cell growth and morphology,count the number of cells in each group after 8 days of culture,and use flow cytometry to detect the immune phenotype of each group of cells.Results After 3 days of cultivation in the control group,a large number of cells died and the quantity significantly de-creased;And all experimental groups showed changes in cell morphology from day 2 to day 8 of cultiva-tion;The number of cells and the proportion of HLA DR,CD1a,and CD83 cells in each experimental group were higher than those in the control group,with the highest in experimental group 3(P<0.05).Conclusion MDP has an amplifying effect on bone marrow DCs in children with AL and promotes their maturation,with a stronger synergistic effect with cytokines.
