Different colony stimulating factor on the effect of acute myeloid leukemia in patients with complete remission of dendritic cell subsets / 中国基层医药

ABSTRACT

Objective To study the granulocyte colony stimulating factor ( G-CSF ) and granulocyte macro-phage colony stimulating factor ( GM-CSF) in complete remission of acute myeloid leukemia ( AML) patients with den-dritic cells(DC)changes in the function and its subsets .Methods 36 cases of complete remission according to AML patients were randomly divided into 3 groups,G group was given G-CSF 200g/d,subcutaneous injection ,GM group were given GM-CSF 200g/d,subcutaneous injection ,the control group were injected with normal saline .The curative effects were compared.Results The expression of G in group DC,CD83 and CD86 on surface of CD80 were lower than that in GM group and C group (t=4.34,5.43,4.54,4.54,5.25,3.54,all P<0.05),GM group,DC expression of CD11c was higher than that of G group and C group (t=4.54,4.27,all P<0.05).G group and GM group DC in promoting lymphocyte proliferation were higher than those in C group (t=4.54,5.64,all P<0.05);group GM DC to promote the ability of CD4 +T lymphocyte proliferation was higher than that of G group (t=3.54,P<0.05).ELISA assay,GM group DC secretion of IL-12 than that of group G and C group;group G DC secretion of IL-10 was higher than that of GM group and C group (t=3.54.4.23,4.32,3.87,all P<0.05).Conclusion G-CSF and GM-CSF can make the complete remission in patients with AML subgroup DC shift ,the bias of G-CSF DC2 and certain immuno-suppressive effect ,while GM-CSF DC subsets of DC 1 and promotes cell immune deviation .
