Objective To study the potential role of macrophage migration inhibitory factor(MIF),Interleukin-17(IL-17) and Interleukin-10(IL-10) in the development of HBV-related liver disease.Methods 48 patients with chronic hepatitis B(HBeAg negative and positive,24 cases;21cases of HBV-DNA negative and 27 cases of HBV-DNA positive),81 cases of hepatitis B patients with decompensated cirrhosis and 48 cases of primary liver cancer patients were collected as the experimental group,26 healthy people were as control group.Serum MIF,IL-17 and IL-10 were measured.Results MIF and IL-17 significantly increased,IL-10 significantly decreased in experimental group,compared with the control group(P<0.05),there was significant difference.In addition,there was no significant difference(P>0.05) between positive and negative of chronic hepatitis B.MIF,IL-17 and ALT levels were positively correlated(r=0.693,P<0.01;r=0.897,P<0.001),IL-10 and ALT was negatively correlated(r =-0.285,P=0.037).Conclusion These results indicated that MIF,IL-17 and IL-10 may participate in the pathological process of HBV-related liver disease,serum levels of MIF,IL-17 and IL-10 appear to reflect the severity of tissue injury in HBV-related liver disease.
