[摘要] 目的 研究慢性乙型肝炎患者外周血T淋巴细胞亚群变化及其临床意义。 方法 对200例慢性乙型肝炎患者和80例健康者,采用流式细胞仪检测T淋巴细胞亚群的改变。 结果 HBeAg阴性慢性乙肝患者CD4+、CD8+、CD4+/CD8+显著高于HBeAg阳性患者,分别为(36.70±3.58)、(32.16±4.51)、(1.72±0.37)和(31.21±4.25)、(28.72±3.23)、(1.54±0.45)(P<0.05)。慢性乙型肝炎患者轻度组、中度组、重度组CD4+ T分别为(40.21±5.26)、(36.25±4.53)、(27.51±4.36),组间比较差异有统计学意义(P<0.05),CD8+ T分别为(31.25±4.55)、(27.19±3.38)、(15.27±2.63),CD4+/CD8+分别为(1.63±0.42)、(1.29±0.32)、(0.75±0.23),组间比较差异有统计学意义(P<0.05)。 结论 慢性乙型肝炎患者机体T淋巴细胞功能有不同程度降低,HBeAg阴性的慢性乙肝患者具有相对较强的细胞免疫状态,随病情程度加重,细胞免疫功能状态亦逐级下降。

[Abstract] Objective To study the possible cause of the difference in cellular immue status in patiens chronic hepatitis B. Methods 200 patients with hepatitis B hospitalized from 2010 to 2011 and 80 cases of healthy subjects were investigated and peripheral T lymphocybe subsets were examined by flow cytometry. Results The quantity of CD4+T、CD8+T、CD4+/CD8+ in HbeAg-negative group was higher than that in HBeAg-positive group,their values were (36.70±3.58)、(32.16±4.51)、(1.72±0.37) and (31.21±4.25)、(28.72±3.23)、(1.54±0.45)(P<0.05),the counts of CD4+、CD8+ and the ratio of CD4+/CD8+ were reduced by in patients with chronic hepatitis B in light group,meidium group and serious group.There was significant difference between the three groups. Conclusion The celllular immune was lower than that in the healthy subjects,cellular immune status was stronger than that in patients with HBeAg-positive,with the worsening of illness,cellular immune status was lower and lower.

慢性乙型肝炎(HBV)感染的自然病程分为免疫耐受期、免疫清除期、非活动或低复制期三个阶段,在免疫清除阶段出现慢性乙型肝炎临床表现,如乏力、纳差、呕吐、黄疸等及ALT升高、HBV-DNA滴度下降、肝组织的坏死炎症。慢性乙型肝炎患者的细胞免疫反应在清除病毒的同时,亦可导致肝细胞损伤,而患者机体免疫反应的不同导致不同的临床表现。笔者应用流式细胞仪检测慢性乙型肝炎患者T淋巴细胞亚群水平,研究其临床意义。

1.1?一般资料
患者来源于2010年4月~2011年5月福建医科大学附属三明第一医院感染科住院的200例慢性乙肝患者,其中慢性轻度组60例,中度组80例,重度组60例;男140例,女60例;年龄16~72岁,平均(42.5±4.3)岁。正常对照组80例为同一医院健康体检者,肝功能正常,甲、乙、丙、戊病毒性肝炎血清标志物为阴性。……
