RESULTS	The values of HBeAg and the log value of HBV DNA in the PEG-IFN alpha-2a group were much lower than the values before the treatment ( t = 2.689 , t = 4.080 , P < 0.01 ) , but there was no difference between before and after treatment in the control group ( t = 1.229 , t = 1.009 , P > 0.05 ) .\
