慢性阻塞性肺疾病患者T淋巴细胞活化与凋亡的变化及临床意义

目的：探讨慢性阻塞性肺疾病（COPD）急性加重期和稳定期患者T淋巴细胞活化与凋亡的变化及临床意义。方法：将64例COPD患者分成2组：急性加重期组（34例）和稳定期组（30例），各组用荧光单抗CD3^ 、CD4^ 、CD25^ 、CD95^ 、CD3^ /CD25^ 、CD8^ /CD28^ 、CD8^ /CD28^-对淋巴细胞进行标记，用流式细胞仪计数。结果：与COPD稳定期相比，急性加重期患者体内CD3^ 、CD95^ 、CD3^ /CD25^ 、CD8^ /CD28^ T淋巴细胞减少，CD4^ 、CD25^ T淋巴细胞无明显变化，CD8^ /CD28^-T淋巴细胞增加。结论：COPD急性加重期患者T淋巴细胞总数减少，亚群发生变化，免疫调节功能紊乱，故在治疗疾病过程中，除对症处理处，必须配合使用调节细胞免疫药物，以改善免疫功能。

Changes of Activation and Apoptosis of T-lymphocyte in Peripheral Blood of Patients With COPD and Their Clinical Significance

Objective To investigate the changes of activation and apoptosis of T-lymphocyte in peripheral blood of patients with chronic obstructive pulmonary disease(COPD) at the attack and relieved stage and their clinical significance. Methods 64 cases of COPD were divided into 2 groups: the acute stage(n=34)and the relieved stage groups(n=30). The T-lymphocytes were marked by fluoromonoantibodies CD 3 +, CD 4 +, CD 25 + , CD 95 +, CD 3 +/CD 25 +, CD 8 +/CD 28 +,CD 8 +/CD 28 - and was counted by flow cytometry . Results Compared with the relieved stage, in patients with COPD at the acute attack period,the CD 3 +, CD 95 +, CD 3 +/ CD 25 +, CD 8 +/ CD 28 - were increased, CD 4 + ,CD 25 + had not obvious change, but CD 8 +/ CD 28 + was increased. Conclusions In COPD at the acute attack stage, the immune function was disordered as the result of the change of T subtype of lymphocytes and the reduction of total T lymphocyte.So except for treatment in accordance with their symptoms,immunodrug of cells should be used in order to raise the immune function of the patients.
