ABSTRACT
Objective:To construct the human DcR3 expression vector and verify its expression in vitro. Methods: 915 bp human DcR3 gene CDS was amplified from porcine lung tissues,and was cloned into eukaryotic expression vector pEF1a-IRES-DsRed-Express2 which show red fluorescence. And then pEF1a-IRES-DsRed-Express2-DcR3 was transfected into LX-2 cells by FuGene HD. Expression of mRNA and protein lever of Human DcR3 were detected by RT-PCR and Western blot. Results:The levels of DcR3 gene transcription and translation in the hepatic stellate cells were significantly increased after transfection with pEF1a-IRES-DsRed-Ex-press2-DcR3 by RT-PCR and Western blot analysis. Conclusion: DcR3 expression vector was successfully constructed and highly expressed in LX-2 cells.
ABSTRACT
Objective: To observe relation among sICAM-1 level in the sera of patients with chronic viral hepatic disease, viral replication and the clinical significance. Methods: The level changes of sICAM-1, IL-1,IL-8 and TNFa in the sera of patients with chronic hepatitis B(CH),chronic severe hepatitis B(CSH) and hepatocirrhosis (HC) were detected by ELISA. Results: The levels of sICAM-1,IL-1,IL-8 and TNFa in sera of the patients with chronic viral hepatic disease were significantly higher than those of healthy control group(P<0.01). The bilirubin level in the sera of patients with chronic viral hepatic disease of different clinical types positively correlated with sICAM-1 and cytokine activities. The sICAM-1 level in the sera of HBV-DNA or HBeAg positive patients was significantly higher than those of negative patients(P<0.05,P<0.01). Conclusion: The sICAM-1 level and activities of cytokine IL-1,IL-8 and TNFa as well as the bilirubin level in the sera of the patients can reflect the necrosis degree of hepatocytes, and the sICAM-1 level and activities of IL-1,IL-8 and TNFa were related to state of HBV carrier or the active degree of HBV in patients with hepatic disease.
ABSTRACT
Abstract Objective: To observe relationship among sICAM-1、TGF-?1, and cellular factor level changes in the sera of patients with chronic viral hepatic disease, viral replication and clinical significance.Methods;The sICAM-1 .TGF-?1, ,IL-1,IL-8 and TNFa level changes in the sera of patients with chronic hepatitis B(CH), chronic severe hepatitis B(CSH) and hepato-cirrhosis(HC) were detected by FJ-ISA. Re-sults: The sICAM-1, IL-1, IL-8 and TNFa levels in sera of patients with chronic viral hepatic disease were significantly higher than those of healthy group( P
