慢性乙型肝炎患者血清XCL1与免疫损伤的相关性分析

Objective To explore the relevance between serum XCL1 levels and liver damage in hepatitis B patients.Methods The serum concentration of XCL1 was detected by enzyme linked immu-nosorbent assay (ELISA).Peripheral blood T-cell subsets were detected by flow cytometry (FCM).Liver function was assayed by automatic biochemistry analyzer, hepatitis B antigen/antibody semi-quantitative index was detected by time-resolved fluorescence analyzer, and HBV-DNA load was detected by automatic fluorescence quantitative PCR.Results Serum concentration of XCL1 in control group ( n = 20), mild chronic hepatitis B (CHB) group ( n =29), moderate CHB group ( n =20) and severe CHB group ( n =26)were (8.24±1.94) pg/ml, (10.99±1.94) pg/ml, (12.83 ±2.59) pg/ml, (13.72 ±3.13) pg/ml,respectively.The concentration of XCL1 in all CHB groups was significantly higher than control group ( P＜ 0.05 ).The concentration of XCL1 in severe CHB group was significantly higher than mild CHB group (P ＜ 0.05).XCL1 was positively correlated with ALT, AST, TBIL and DBIL, and the coefficients were (r =0.463、 0.472、 0.413、 0.440, P ＜0.01 ), respectively.The serum XCL1 levels in hepatitis B virus with low load group was lower than hepatitis B virus with high load group.The percentage of CD4 + T in hepatitis B virus with low load group and high load group were (41.26 ± 11.33)%, (33.01 ± 5.96)%,and the difference was statistically significant.Conclusion Serum concentrations of XCL1 were closely related to the degree of liver inflammation in hepatitis B patients.XCL1 may be involved in the process of chronic hepatitis B.
