RESUMO
Objective To study the content of IL-8 in the peripheral blood and the expression of its mRNA in liver biopsy tissue of patients with hepatocirrhosis.Methods The patients with typical hepatocirrhosis resulted from HBV infection were selected.The IL-8 concentrations in peripheral blood of the Datients were evaluated with ELISA.The content of IL-8 mRNA in liver biopsy was measured by real-time PCR.The level of IL-8 mRNA was surrogated by lg cDNA/lg GAPDH.Reslllts The levels of IL-8 in the serum and its mRNA in hepatic tissue of patients with hepatoeirrhosis were(43 1.39±97.39)μg/L and 1.3647±0.2203,respectively,which were significantly higher than those of control group.MoreoCer,the levels of IL-8 in the serum and IL-8 mRNA in hepatic tissue of patients with positive HBV-DNA were (502.43-4-102.24)μg/L and 1.51424±0.2245,respectively,and both ofwhich were higher than those of patients without HBV-DNA replication(P<0.0l,P<0.05).And the levels of IL-8 in the selqlm and its mRNA in hepatic tissue of patients with higher ALT.AST also increased significantly.compared with those in control group(P<0.01).Conclusion The levels of IL-8 in the peripheral blood and the IL-8 mRNA in liver biopsy tissue of patients with hepatocirrhosis increase.which are related to the degree of HBV-DNA replication and the damage of hepatocytes.The IL-8 plays a key role in local inflammatory infihration of liver and the progression of post-hepatitis cirrhosis.
RESUMO
Objective:To study the expression of IP-10 and its mRNA in liver biopsy of patients with cirrhosis.Methods:The typical patients with cirrhosis after HBV infection were selected,and their serum IP-10 concentrations were evaluated with ELISA,the content of IP-10 mRNA in liver biopsy was measured by Real-time PCR.The level of IP-10 mRNA was represented by lg cDNA/lg GAPDH.The expression of IP-10 in liver biopsy tissue was detected by SP immunohistochemistry stain.Results:The levels of IP-10 in serum and its mRNA in liver biopsy of patients with cirrhosis were (299.3?77.2)pg/ml and (0.856 3?0.150 6),lg cDNA/lg GAPDH respectively,which were significantly higher than those of control groups(P
