摘要: 目的:探讨不同分期的多发性骨髓瘤(MM)患者外周血淋巴细胞各亚群细胞比例与白细胞介素-6(IL-6)表达变化。方法:用流式细胞仪检测35例初治MM患者及10例对照者的外周血淋巴细胞亚群各细胞表达水平,用ELISA法检测IL-6水平。结果:与对照者相比,MM患者的CD4+、CD4+/CD8+明显降低(P<0.01),均与MM分期严重程度呈负相关(r=-0.780,-0.832,P<0.01);MM患者的CD8+显著增加(P<0.01),与MM分期严重程度呈正相关(r=0.737,P<0.01)。MM患者的IL-6水平较对照者显著增加,与MM分期严重程度呈正相关(r=0.961,P<0.01)。结论:IL-6表达增加及T淋巴细胞亚群数目异常变化可能是MM患者免疫异常的机制之一,两者能作为观察MM患者病情严重程度的指标。Abstract: Objective:To investigate the changes of T lymphocytes subsets and expression of interleukin-6 (IL-6) in peripheral blood of the patients with multiple myeloma (MM) in different stages.Method:The peripheral blood was collected from 35 newly diagnosed patients with MM and 10 normal controls.Flow cytometry was used to detect T lymphocyte subsets in peripheral blood,and enzyme-linked immunosorbent assay was used to determine the level of IL-6.Result:Compared with normal controls,the number of CD4+ and the ratio of CD4+/CD8+ in MM patients decreased significantly (P<0.01),and were negatively correlated with the degree of MM (r=-0.780,-0.832,P<0.01);The number of CD8+ increased significantly,and was positively related with the degree of MM (r=0.737,P<0.01);The level of IL-6 increased significantly,and was positively related with the degree of MM (r=0.961,P<0.01).Conclusion:Increase of IL-6 expression and abnormality of T lymphocyte subsets may be one of the mechanisms for cellular immun dysfunction in patients with MM,both of them can serve as indexes for observing the disease state.
