摘要
目的了解IL-2等细胞因子在白血病发病机制中的作用。方法测定了51例急性白血病患者PBMNC培养上清中IL-2、IL-6水平及血清sIL-2R、TNFα水平。结果(1)急性白血病患者PBMNC培养上清的IL-2水平显著低于正常(P<0.01)及CR组(P<0.05);而IL-6水平显著高于正常及CR组(P<0.01)。(2)急性白血病患者血清sIL-2R及TNFα水平显著高于正常及CR组(P<0.01)。(3)急性白血病患者血清sIL-2R水平与其外周血幼稚细胞比例呈正相关(r=0.410,P<0.05);在M5患者中血清sIL-2R与TNFα水平正相关(r=0.874,P<0.01)。结论急性白血病患者存在着细胞因子网络的失调,并在急性白血病的发生、发展中起一定的作用。
Objective Recombinant human hematopoietic growth factor (rhHGF) and chemotherapeutic drugs combined treatment is a new strategy which may be useful cure for acute myeloid leukemia. MethodsThe sensitivity of Ara C to mononuclear cell with acute leukemia was detected by INT.Results The results suggested enhancement of the cytotoxicity of Ara C by G CSF、IL 3 or GM CSF.However,none of the HGF significantly affected the drugs cytotoxicity of MNC. The different effects of rhHGF on the sensitivity of the chemotherapeutic drugs in normal versus leukemic cells. Conclusion rhHGF combined with chemotherapeutic drugs may indicate a role for rhHGF in enhancing the selectivity of drugs toward leukemic myeloblasts.
