title: [Therapeutic efficacy of combined application of lamivudine and bushen recipe in treating chronic hepatitis B and its influence on YMDD motif].
abstract: OBJECTIVE
  To observe the effect of combined application of Lamivudine and Bushen recipe (BSR) in treating patients with chronic hepatitis B (CHB) and its influence on tyrosine-methionine-aspartate-aspartate (YMDD) motif.
  
  
  METHODS
  Eighty-eight patients of CHB with positive HBV-DNA were divided into 3 groups, Group A treated with Lamivudine, Group B treated with Lamivudine plus BSR1 and Group C treated with Lamivudine plus BSR2, the serum HBV-DNA, hepatic biological parameters and YMDD motif mutation were observed.
  
  
  RESULTS
  The positive rate of HBV-DNA (6.45%) and YMDD motif mutation (3.23%) in Group C were lower than those in Group A respectively, after 52 weeks treatment.
  
  
  CONCLUSIONS
  Combined application of Lamivudine and BSR could enhance the therapeutic effect in treating CHB to certain extent, and could reduce the mutation of YMDD motif.
