不同病毒载量HBV感染者外周血T淋巴细胞亚群和转化生长因子β的变化及意义

目的通过检测不同病毒载量慢性乙型肝炎(CHB)患者和HBV携带者(ASC)外周血T淋巴细胞各亚群变化的规律,探讨T淋巴细胞与人转化生长因子(TGF)β、ALT及TBil相关性。方法选择2012年7月至2012年12月兰州市第二人民医院收治的175例HBV感染者作为研究对象,分为ASC组(112例)、CHB组(63例),以同期健康体检者84例作为对照组。运用流式细胞术检测3组血清中T淋巴细胞亚群水平,同时检测肝功能指标等。正态分布的计量资料多组间比较采用方差分析,偏态分布的计量资料组间比较采Kruskal-Wallis H秩和检验。结果与健康对照组相比,ASC和CHB组TGFβ表达水平显著升高(...

Summary:目的通过检测不同病毒载量慢性乙型肝炎(CHB)患者和HBV携带者(ASC)外周血T淋巴细胞各亚群变化的规律,探讨T淋巴细胞与人转化生长因子(TGF)β、ALT及TBil相关性。方法选择2012年7月至2012年12月兰州市第二人民医院收治的175例HBV感染者作为研究对象,分为ASC组(112例)、CHB组(63例),以同期健康体检者84例作为对照组。运用流式细胞术检测3组血清中T淋巴细胞亚群水平,同时检测肝功能指标等。正态分布的计量资料多组间比较采用方差分析,偏态分布的计量资料组间比较采Kruskal-Wallis H秩和检验。结果与健康对照组相比,ASC和CHB组TGFβ表达水平显著升高(P均〈0.05),CD3+、CD4+T淋巴细胞百分数显著降低(P〈0.05或P〈0.01),CD4+与CD8+T淋巴细胞比值显著降低(P〈0.01),CD8+T淋巴细胞百分数显著升高(P〈0.05或P〈0.01)。ASC与CHB组HBeAg阳性组和HBeAg阴性组患者CD3+、CD4+T淋巴细胞百分数均降低,CD8+T淋巴细胞百分数升高,CD4+与CD8+T淋巴细胞百分数降低。结论 TGFβ可能参与了CHB的发病过程,其免疫抑制作用可能是通过对T淋巴细胞、抗原递呈细胞成熟分化的抑制等多个环节发挥作用。

Objective To study the changes in peripheral blood T cell subsets among chronic hepatitis B( CHB) patients and asymptomatic hepatitis B virus( HBV) carriers( ASC),who have different viral loads,and to investigate the correlation of T cell subsets with transforming growth factor beta( TGFβ),alanine aminotransferase,and total bilirubin. Methods A total of 175 HBV infection patients admitted to our hospital from July to December,2012 were recruited and divided into ASC group( n = 112) and CHB group( n = 63); 84 healthy controls who underwent physical examination in the same period were selected as control group. The percentages of T cell subsets in serum were determined by flow cytometry,and liver function parameters were measured. For normally distributed continuous data,comparison between groups was made by analysis of variance; for non- normally distributed continuous data,comparison between groups was made by Kruskal- Wallis H rank sum test.
