title: [Study of relativity between HBV M and HBV DNA in the cases with hepatitis B].
abstract: OBJECTIVE
  Serum samples of 414 cases with hepatitis B were detected for hepatitis B markers (HBV M) and HBV DNA, in order to investigation the relationship between HBV M and HBV DNA, and its clinical significant.
  
  
  METHODS
  HBV M and HBV DNA were detected by ELISA and blot hybridization methods respectively.
  
  
  RESULTS
  HBV DNA positive rates in the groups of acute and chronic hepatitis B were higher than that in the group of liver cirrhosis (P <0.01); HBV DNA positive rates had no apparent difference between the HBsAg, HBeAg, anti-HBc positive group and the HBsAg, anti-HBs, anti-HBc positive group. Direct relativity was shown between the titer of HBsAg and/or HBeAg and the positive rate of HBV DNA.
  
  
  CONCLUSIONS
  HBV DNA can be treated as a sign of HBV activity; the appearance of anti-HBs can not be taken as indicator of ceasing of HBV replication; the changes in HBsAg and HBeAg titers may be used as clinical evaluation on HBV replication and index for anti-viral therapeutic effect.
