摘 要:目的探讨HBeAg(+)与HBeAg(-)HBV携带者外周血中CD4+CD25+调节性T淋巴细胞(Treg)的变化及其意义。方法 HBeAg(+)与HBeAg(-)HBV携带者两组各50例患者,应用流式细胞仪测定外周血CD3+T淋巴细胞所占比例、CD4+和CD8+T淋巴细胞所占比例及其比值、CD4+CD25+Treg所占比例;以同期门诊健康体检者20例为健康对照组。结果与健康对照组相比,HBeAg(+)与HBeAg(-)HBV携带者,在外周血CD3+T淋巴细胞、CD4+与CD8+T淋巴细胞所占比例差异无统计学意义。CD4+与CD8+T淋巴细胞比值,在HBeAg(+)HBV携带者有升高趋势,但与HBeAg(-)HBV携带者和对照组比较差异无统计学意义。HBeAg(+)HBV携带者,CD4+CD25+Treg所占比例较对照组明显升高,而HBeAg(-)HBV携带者,CD4+CD25+Treg所占比例较对照组明显降低,差异均有统计学意义。结论尽管肝功能在正常范围,HBeAg(+)与HBeAg(-)HBV携带者外周血CD4+CD25+Treg比例不同,HBeAg(+)HBV携带者高于健康对照组,而HBeAg(-)HBV携带者低于健康对照组,提示HBeAg(+)与HBeAg(-)HBV携带者处于不同的免疫状态。Objective To investigate the Changes and Value of the Proportion of CD4+CD25+regulatory T cells(Treg) in HBeAg(+) and HBeAg(-) chronic asymptomatic hepatitis B virus carriers(ASC).Methods Patients with HBeAg(+) ASC(n=50),HBeAg(-)ASC(n=50) and normal subjects(n=20) were recruited in this study.Flow cytometric analysis was used to detect the quantification of peripheral CD3+,CD4+ and CD8+T lymphocyte subgroup,CD4+CD25+Treg.Results The proportion of CD3+,CD4+,CD8+T lymphocyte subgroup has no significant difference among healthy controls,HBeAg(+) and HBeAg(-) ASC.The ratio of CD4 and CD8 in HBeAg(+) patients was elevated,but there was no significant difference between healthy controls and HBeAg(+) patients.Contrast to normal subjects,the ratio of CD4+CD25+Treg increases in HBeAg(+) ASC,but decreases obviously in HBeAg(-) ones(P0.05).Conclusion Although having normal hepatic function,HBeAg(+) and HBeAg(-) ASC have different ratio of peripheral CD4+CD25+Treg,Our findings suggest that HBeAg(+) and HBeAg(-) ASC stand in different immune state.
