Compared two groups of patients with virus should be The incidence of adverse reactions and a sustained virological response. Results of the observation group (SVR), early virological response (EVR) and virological nonresponders (NR) were better than the control group; the observation group of adverse reaction rate was 16.67%, the adverse reaction rate in the control group was 46.67%, two groups of adverse reactions the observation group was better than the control group, and P<0.05, the difference was statistically significant. Conclusion PEG-IFN in patients with chronic hepatitis C alpha -2a combined with Leigh Bhave Lin treatment, the clinical efficacy, side effects are relatively small, with further promotion and Application value
