摘 要:目的 探討CLL患者骨髓中INF-γ、IL-2、IL-4、IL-10及IL-1β水平的變化及意義。方法 選取我院初診CLL患者66例為病例組,根據Binet分期分為BinetA期29例,BinetB期21例,BinetC期16例;選取同期來我院健康體檢者30例為對照組,另取38例治療中的CLL患者為治療組。應用流式細胞儀分析各組患者骨髓INF-γ、IL-2、IL-4、IL-10、IL-1β表達,觀察在CLL患者不同時期的表達差異。結果 IFN-γ、IL-2表達在CLL各組中均低于對照組(P<0.05),而BinetC期患者表達低于BinetB期(P<0.05),BinetB期低于BinetA期(P<0.05),與Binet分期呈負相關。INF-γ、IL-2在CLL治療后雖高于BinetA期,但P>0.05,而低于對照組(P<0.05)。IL-4、IL-10、IL-1β表達高于對照組(P<0.05),BinetB期高于BinetA期(P<0.05),BinetC期高于BinetB期(P<0.05),與Binet分期呈正相關。治療后IL-4、IL-10、IL-Iβ與BinetA期比較有所降低,但P>0.05,與對照組比較仍高于對照組(P<0.05)。結論 CLL患者骨髓微環境細胞因子表達紊亂,Th1類細胞因子INF-γ、IL-2隨著CLL Binet分期的進展逐漸減低,IL-4、IL-10、IL-1β則逐漸增高,與CLL的發生、發展相關。

Abstract:Objective To investigate the changes and significance of INF-γ,IL-2,IL-4,IL-10 and IL-1β in marrow of CLL patients.Methods 66 patients with newly diagnosed CLL in our hospital were selected as the case group.According to Binet stage,there were 29 cases of BinetA stage,21 cases of BinetB stage and 16 cases of BinetC stage.30 cases of healthy physical examination in our hospital were selected as control group.The CLL patients in the treatment group were the treatment group.Another 38 patients with CLL under treatment were treated.The expressions of INF-γ,IL-2,IL-4,IL-10 and IL-1β in marrow of each group were analyzed by flow cytometry,and the expression differences in different periods of CLL patients were observed.Results The expressions of IFN-γ and IL-2 in CLL group were lower than those in control group(P<0.05),while those in BinetC stage were lower than BinetB stage(P<0.05),and BinetB stage was lower than BinetA stage(P<0.05),negatively correlated with Binet staging.INF-γ and IL-2 were higher than the BinetA phase after CLL treatment,but P>0.05,which was lower than the control group(P<0.05).The expressions of IL-4, IL-10 and IL-1β were higher than those of the control group(P<0.05),the BinetB phase was higher than the BinetA phase(P<0.05), the BinetC phase was higher than the BinetB phase(P<0.05),positively correlated with Binet staging.After treatment,IL-4,IL-10,IL-Iβ and BinetA phase were decreased,but P>0.05,which was still higher than the control group(P<0.05).Conclusion The expression of cytokines in bone marrow microenvironment of patients with CLL is disordered.The cytokines of Th1 type cytokines INF-γ and IL-2 decrease with the progression of CLL Binet stage,and IL-4,IL-10 and IL-1β gradually increase,and CLL occurrence and development are related.

慢性淋巴細胞白血病(chronic lymphocytic leukemia,CLL)是以成熟B淋巴細胞克隆性增殖且腫瘤細胞凋亡受阻、生存期延長為特征的異質性惡性疾病[1]。目前認為CLL的發病機制與免疫異常有關,免疫功能紊亂在其發生、發展過程中起著重要作用[2]。細胞因子是一類小分子分泌蛋白,也是機體免疫系統的重要組成部分,在維持骨髓微環境乃至全身免疫穩態中發揮重要作用。本文應用流式細胞儀檢測CLL不同分期及治療后骨髓微環境中INF-γ、IL-2、IL-4、IL-10及IL-1β水平的變化,探討腫瘤微環境中細胞因子在CLL發生、發展中的意義。
