摘要 目的:探讨白细胞介素10(IL-10)对慢性心力衰竭(CHF)患者外周血单个核细胞(PBMCs)促炎性细胞因子分泌的影响。方法:15例CHF患者和15例健康人清晨采外周静脉血8ml,肝素抗凝,用淋巴细胞分离液分离出PBMCs。分3组对PBMCs进行培养:用1640培养基培养作为空白组;用含脂多糖(LPS,2mg/L)的1640培养基作为LPS组;用含LPS(2mg/L)和IL-10(20μg/L)的1640培养基培养作为IL-10组。把含有PB-MCs的培养板放在含5%二氧化碳的孵箱中37℃孵育24h,收集培养液离心,吸取上清液。检测肿瘤坏死因子α(TNF-α)、白细胞介素1β(IL-1β)和白细胞介素6(IL-6)水平。结果:CHF患者无论是空白组、LPS组还是IL-10组,TNF-α、IL-1β和IL-6水平均比健康人增高,均差异有统计学意义(均P<0.01)。LPS组比空白组TNF-α、IL-1β、IL-6升高,IL-10组比LPS组TNF-α、IL-1β、IL-6降低,均差异有统计学意义(P<0.05,P<0.01)。结论:CHF患者PBMCs分泌炎性细胞因子增加,而IL-10具有明显的抑制作用。
