ABSTRACT

Aim To explore new ways for developing anticancer drugs by the separation of pigment from Fu-sarium species JN158 ( Fusarium sp JN158 ) , the iden-tification of its structure, the screening of anticancer components and the study of its partial mechanism. Methods Pigment separation was done by HPLC, structural analysis by UV, IR, NMR, the screening of anticancer activity by MTT. Western blot was used to analyze the protein expression of CyclinD1, NF-κB, VEGF in tumor cells. Results The results showed that the pigment from Fusarium produced a total of six different peaks, of which peak Ⅵ was the anthocya-nins. Its molecular weight is about 382, molecular for-mula is C17 H18 O10 . According to investigation, this pig-ment was probably a new compound, which could in-hibit the proliferation of MCF-7 cells markedly ( IC50:0.011mmol·L-1 ,P<0.05;the control medicine ube-nimex IC50:10 mmol · L-1 ) in a concentration-de-pendent manner, and had no effect on human umbilical cord intravenous endotheliocyte ( HUVEC ) . The influ-ence on the gene expression of CyclinD1, NF-κB, VEGF in MCF-7 cells varied with the concentration of this compound. The Western blot results showed that VI pigment compound inhibited CyclinD1, NF-κB, VEGF gene expression (P<0.05 or 0. 01),compared with the control group. Conclusion The Ⅵ pigment compound from Fusarium sp JN158 could inhibit MCF-7 proliferation by inhibiting CyclinD1, NF-κB, VEGF gene expression. The compound may be a promising compound against breast cancer.

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

Objective:To analyse clinical signification of four kinds of autoimmune antibodies in the patients with viral hepatitis.Methods:ANA RF,anti TM and dsDNA Ab in sera of patients with viral hepatitic disease were detected by means of indirect immune fluerscence(IIF) and ELISA.Results:12 of 63 (19.1%) were only one kind of autoimmune antibody in sera of patients with hepatitis B and 12 of 40(30%) of patients with hepatitis C.There were significantly higher than those of alcoholic and drug hepatitis group(P
