Abstract:
Objective To study the relationship between histological activity index and serum of tumor nec-rosis factor-α( TNF-α) ,peripheral blood T cell subsets in patients with chronic hepatitis B.Methods Histopatholog-ical examinations were performed in 237 patients with chronic hepatitis B and 12 controls.The histological activity index( HAI) were analyzed by knodels method.These patients were divided into the four groups according to histologi-cal activity index classification:the control group(n=12),mild group(n=67),moderate group(n=89),and severe group(n=81).The serum levels of TNF-αwere determined by ELISA,and peripheral blood T cell subsets were ana-lyzed by flow cytometry.Results The serum level of TNF-αin the mild group[(29.65 ±10.15)μg/L],moderate group[(38.96 ±7.32)μg/L]and severe group[(47.73 ±6.99)μg/L]were higher than those in the control group [(13.78 ±6.40)μg/L](q=14.38,19.97,24.83,all P<0.05),significant positive correlation lied between the histological activity index classification and the serum level of TNF-α(r=0.708,P<0.05).The rate of CD8+cells in the moderate group[(27.66 ±6.63)μg/L]and the severe group[(28.98 ±5.92)μg/L]were higher than those in the control group[(22.32 ±1.84)μg/L](q=3.84,4.76,all P<0.05),and the ratio of CD4+/CD8+in the moderate group(1.32 ±0.37) and the severe group(1.19 ±0.30) were lower than those in the control group(1.67 ±0.14) (q=4.20,5.72,all P<0.05),but the rate of CD8+cells and the ratio of CD4+/CD8+showed no significance among the mild group,moderate group and severe group.Conclusion TNF-αand disorder of cellular immunity may play an important role in the development and progression of intrahepatic vascular lesion.
