title: [Significance of polypeptide antigen of HCVE2/NS1 relative conservation region in detection of anti-HCV].
abstract: OBJECTIVE
  In order to study the significance of HCVE2/NS1 relative conservation region antigen.
  
  
  METHODS
  EIA was established with HCVE2/NS1 relative conservation polypeptide antigen, as well as serum HCV RNA and ALT in patients with HCV infection.
  
  
  RESULTS
  The positive rate of 96 cases patients who were infected by HCV is 41.67%, acute 13.55% and chronic 25.04%, and we found that there were 3 cases weak positive in 40 healths; Agreement rate is 62.5% in 40 cases of the positive of anti-E2/NS1 in sera with HCVRNA, and they have relation. In ALT level in sera, acute infection of HCV is higher than chronic (P < 0.05).
  
  
  CONCLUSIONS
  There are virus necleic acid in sera when anti-HCVE2/NS1 appearence positive; however, antibody of anti-E2/NS1 relative conservation region has the some neutralive actions, and this humor immunity may have the actions in clearing virus, but wether anti-body of anti-E2/NS1 relative conservation of HCV is or not neutralive antibody well be investigated further.
