ABSTRACT
Objective To investigate the effects of liver function and tumor markers by nucleoside analogues Entecavir on patients with liver cirrhosis after hepatitis B.Methods 90 patients with liver cirrhosis after hepatitis B were selected, according to the different drugs were divided into experimental group and control group.Liver function and levels of tumor markers were compared after experiment.Results Two groups of patients with male to female ratio, average age, course of disease, no significant difference in general data of hepatitis B virus DNA content, comparable (P>0.05);Compared with the control group, the experimental group HBV DNA level is low, the negative rate was significantly higher (P<0.05);Compared with the control group, the experimental group ALT, AST and TBiL levels were significantly increased(P<0.05), ChE, AlB were significantly decreased (P<0.05);Compared with the control group, the experimental group CEA, AFP, CA125 and lower CA199 levels (P<0.05).Conclusion Nucleoside drugs can significantly improve liver function in patients with liver cirrhosis after hepatitis Band tumor markers indicators, and it is significance for treatment of liver cirrhosis after hepatitis.
ABSTRACT
Indigo and indigo-like pigments are widely used in the industry of textile, food and medicine. Now people pays more and more attention to developing an alternative method of indigo production which is "environment-friendy", especially microbial biosynthesis of indigo. Many microorganisms involved in the biosynthesis of indigo have been isolated and characterized, and monooxygenase and dioxygenase have been identified to catalyze indigo biosynthesis. Some genes encoding for these enzymes have been cloned and used to construct "engineering bacteria". With this kind of bacteria, more efficient fermentation systems for indigo production have been exploited. In the meantime, biotransformation of the indigo produced by microorganisms has been under investigation. These progresses will bring us a greener method of indigo and indigo-like pigments production.
