ABSTRACT
Objective To detect the expression and clinical significance of stro-mal cell derived factor-1 (SDF-1) and CXC chemokine receptor 4 (CXCR4) in peripheral blood of patients with hepatitis C cirrhosis.Methods From January 2015 to January 2018,120 patients with hepatitis C cirrhosis in our hospital were selected as the subjects,including 60 patients with compensated hepatitis C cirrhosis and 60 patients with decompensated hepatitis C cirrhosis,and 60 hepatitis C patients without cirrhosis in the same period were selected as the control group.Enzyme linked immunosorbent assay (ELISA) was used to detect the expression levels of SDF-1 and CXCR4 in peripheral blood;the correlation between SDF-1 and CXCR4 expressions in compensated cirrhosis and decompensated cirrhosis patients was analyzed.Results The expression levels of SDF-1 and CXCR4 in peripheral blood samples of patients with decompensated cirrhosis of hepatitis C were significantly higher than those of patients with compensated cirrhosis of hepatitis C (P ＜ 0.05);the expression levels of SDF-1 and CXCR4 in peripheral blood samples of patients with compensated and decompensated cirrhosis of hepatitis C were significantly higher than those of control group (P ＜ 0.05);the expressions of SDF-1 and CXCR4 in peripheral blood of patients with compensated and decompensated cirrhosis of hepatitis C were positively correlated (r =0.684,P ＜ 0.05,r =0.765,P ＜ 0.05).Albumin (AlB) level in peripheral blood of cirrhosis group was significantly lower than that of control group (P ＜ 0.05);alanine aminotransferase (ALT),aspartate aminotransferase (AST),total bilirubin (TBIL),while fasting insulin (FINs) and interleukin (IL)-6 in cirrhosis group were higher than those of control group (P ＜ 0.05);SDF-1 level and CXCR4 level were positively correlated with AlB,FINs and IL-6 (P ＜ 0.05);multiple regression analysis showed that FINs,IL-6,SDF-1 and CXCR4 were risk factors for hepatitis C cirrhosis.Conclusions The levels of SDF-1 and CXCR4 in peripheral blood of patients with hepatitis C cirrhosis increased,and the levels of SDF-1 and CXCR4 in peripheral blood were positively correlated,suggesting that they may be involved in the regulation of the occurrence and development of hepatitis C cirrhosis.
