Brief Summary
Pegylated interferon α-2a(Peg-IFN-α) not only inhibit viral replication, but also play an important role in immune regulation, while Nucleoside analog(ue) drugs only inhibit viral replication. In hepatitis B infection, NKs are the main effector cells in early antiviral innate immune response. This study was aimed at investigating the changes of NKs frequency and function, and the expression of costimulatory molecules during Peg-IFN-αand nucleoside analog(ue) therapy.Meanwhile, investigators want to verify whether Peg IFN - alpha suppressed the virus and the reduction of virus led to the recovery of NKs function, or Peg IFN - alpha enhanced NKs function which gave rise to the decline of the virus.

Study Arms (2)
experimental group
EXPERIMENTALpatients who were untreated ever in immune-active phase were given subcutaneous injection of Peginterferon Alfa-2a with starting dose of 180 mg/weekly till 48 weeks.
control group
NO INTERVENTIONpatients who were untreated ever in immune-active phase took Nucleoside Analogues for maintenance treatment.
Interventions
patients untreated in immune-active phase were given subcutaneous injection of Peginterferon Alfa-2a with starting dose of 180 mg/weekly in experiment group.
