目的:探讨B细胞非霍奇金淋巴瘤(B cell Non-Hodgkin′s Lymphoma,B-NHL)患者骨髓单个核细胞( BMMC)表面CD40、 CD40 L的表达情况及变化规律,分析CD40、CD40 L表达与淋巴瘤发病、侵袭性及预后的关系及意义。方法采集20例初诊B-NHL伴有骨髓侵犯的患者(实验组)的骨髓标本及12例健康者(对照组)的骨髓标本,分离单个核细胞,采用直接荧光抗体标记,应用流式细胞仪检测细胞表面CD40、CD40 L的表达情况。相关实验结果进行统计学比较。结果(1) B-NHL中CD40阳性率(45.78±3.82)%显著高于正常对照组(13.99±2.20)%,P<0.01;B-NHL中CD40L阳性率(3.44±0.88)%显著低于正常对照组(10.64±1.03)%,P<0.01;(2) B -NHL 伴有骨髓侵犯的患者CD40、CD40L阳性率与病理类型、LDH值、全身症状呈显著相关,P<0.05;(3) B-NHL伴有骨髓侵犯的患者中CD40与CD40L表达呈负相关,r =-0.47,P<0.05。结论(1) CD40、CD40L阳性率与病理类型、LDH值、全身症状密切相关,其可能与B-NHL的侵袭性及预后有关;(2) B-NHL患者中CD40表达的增高、CD40L表达的减少可能是影响其发病的因素之一;(3) B-NHL患者中CD40L表达的减少可能与肿瘤免疫逃逸机制有关。

Objective To explore the expressions and changing regularity of CD 40,CD40L in surface of bone marrow mononuclear cell (BMMC)of patients with B -cell Non-Hodgkin′s Lymphoma.To study the rela-tionship between the expressions of CD 40,CD40L and the pathogenesis、infestation、prognosis,clinical implication of patients with Lymphoma .Methods Twenty bone marrow specimens of B -NHL ( experimental group ) and twelve healthy bone marrow specimens(contiol group)were collected.To separate mononuclear cell,we used di-rect fluorescent antibody to mark cells ,the expressions of CD40 and CD40L were determined by flow cytometry . Statistical study was done between two groups .Results (1) CD40 positive overexpression rate in B -NHL sam-ples(45.78 ±3.82)%was higher than that in normal samples (13.99 ±2.20)% (P<0.01);CD40L positive overexpression rate in B -NHL samples(3.44 ±0.88)% was lower than that in normal samples (10.64 ± 1.03)%(P<0.01).(2)There were significant correlations between the positive overexpression rates of CD 40, CD40L and pathology category,lactic dehydrogenase(LDH)levels,the whole body symptoms in B -NHL patients who suffered from bone marrow involvment(P<0.05).(3)There were negative correlations between CD40 and CD40L expressions in B-NHL patients who suffered from bone marrow involvment (r=-0.47,P<0.05).Con-clusions (1) There are close correlations between CD 40、CD40L and pathology category ,LDH levels and the whole body symptoms,which can likely be correlative in judging the B -NHL prognosis and infestation.(2)High CD40 expressions and low CD40L expressions may probably be one of etiologic factors of B -NHL.(3) Low CD40L expressions may probably be related with the mechanism of tumor escape .
