乙型病毒性肝炎临床转归与机体细胞免疫功能状况的相关性研究
曾跃红等[摘要] 目的 探讨乙型病毒性肝炎患者外周血T淋巴细胞亚群、血清干扰素-γ(IFN-γ)和肿瘤坏死因子-α(TNF-α)的变化与疾病临床转归的关系。 方法 收集2009年1~12月益阳市中心医院诊治的352例乙肝病毒性肝炎患者,并选择同期健康人82例作为对照。采用流式细胞仪检测外周血T淋巴细胞亚群(CD3+、CD4+、CD8+),ELISA法检测细胞外血清IFN-γ和TNF-α,比较乙肝病毒性肝炎患者与健康人外周血T淋巴细胞亚群及IFN-γ和TNF-α水平。 结果 不同HBV-DNA载量的患者CD3+、CD4+、CD8+、CD4+/CD8+、IFN-γ和TNF-α水平与健康人比较,差异均有统计学意义(P 0.05)。IFN-α治疗患者治疗6个月和随访1、3、5年时,HBV-DNA阴转率均高于保肝护肝基础治疗患者(P < 0.05)。 结论 乙型病毒性肝炎患者存在细胞免疫功能紊乱,其功能状态直接影响临床转归,动态监测患者T淋巴细胞亚群和血清IFN-γ、TNF-α对乙型病毒性肝炎的诊断、治疗、预后评估及个体化治疗都有重要的意义。

[Abstract] Objective To explore the correlation between the change of T cell subgroups, serum IFN-γ, TNF-α in patients with hepatitis B and clinical prognosis. Methods From January to December 2009, in the Center Hospital of Yiyang City, 352 patients with hepatitis B were selected, and 82 healthy people were selected as control at the same time. Flow cytometer was used to detect the T cell subgroups (CD3+, CD4+, CD8+), and the level of serum IFN-γ and TNF-α were detected by ELISA, the results were compared. Results The levels of CD3+ ......
