摘要: 目的:探讨多器官功能障碍综合征(MODS)患者外周血CD4+ CD25+调节性T细胞在治疗前后的改变及与病情的关系。方法: 采集10例MODS患者在治疗前和治疗后1周及10例健康人的外周抗凝血,应用CD4(PE-CY5)、CD25(FITC)和CD127(PE)特异性荧光抗体标记后,通过流式细胞仪对CD4+ CD25+ CD127-调节性T细胞进行三色荧光抗体检测。结果:MODS患者治疗后外周血中CD4+ CD25+ CD127-调节性T细胞的百分比(2.11%±0.33%)低于治疗前(7.44%±1.59%)(P<0.05),但仍高于正常对照组(0.77%±0.09%)(P<0.05)。结论:MODS患者CD4+ CD25+ CD127-调节性T细胞的比例增加,并可能在 MODS的发生发展中起抑制作用。

Abstract: Abstract:Objective To explore the change of CD4+ CD25+ regulatory T cells(Treg) from peripheral blood in patiens with multiple organ dysfunction syndrome(MODS) before and after treatment and its significance.Methods The  frequencies of CD4+ CD25+ CD127-Treg were detected in 10 patients with MODS respectively before treatment and 1 week after treatment and 10 healthy donors by flow cytometry labeled with specific fluorescent antibodies,such as anti-CD4(PE-CY5) ,anti-CD25(FITC) and anti-CD127(PE).Results The frequency of CD4+ CD25+ CD127-Treg in patients after treatment(2.11%±0.33%) was significantly lower than before treatment (7.44%±1.59%) (P<0.05),and they were all higher than that of healthy donors(P<0.05).Conclusion The frequency of CD4+ CD25+ CD127-Treg increases in patients with MODS.That may surpress the process of MODS.
