Abstract:
Objective To study the clinical value of detection of peripheral blood natural killer(NK) cells subsets in patients with malignant hematological diseases.Methods A total of 100 patients with malignant blood disease were enrolled from March 2014 to April 2016 as the observation group,including 50 cases in acute stage and 50 cases in mild stage.At the same time,100 health subjects were enrolled as the control group.The number of NK cells in peripheral blood and the changes of subgroups were compared.Results The number of NK cells in the different groups were compared,the absolute numbers and relative numbers of NK cells in the acute phase of leukemia and lymphoma were much lower than those in the control group(P<0.05).While the absolute number and relative number of NK cells in mild stage of leukemia and lymphoma were higher than that in acute phase(P<0.05).After treatment,the absolute number and relative number of NK cells in patients with leukemia and lymphoma were higher than before treatment(P<0.05).Before treatment,levels of CD56bright and CD56dim in patients with leukemia and lymphoma were statistically different with those of control group(P<0.05).After treatment,CD56bright and CD56dim levels were significantly improved in both groups(P<0.05).Conclusion The number of peripheral blood NK cells in patients with hematological malignancies could be reduced,and the cells function might be compromised.Detection of NK cell subsets could be with guiding significance in the treatment of malignant hematologic disease.
