Objective   To explore the difference of western blot(WB)bands pattern in various HIV-1 polsitive people by investig ate the WB bands of HIV-1 antibody.

  Methods   People diag nosed as HIV-1 posotive person by WB.

  Results   The WB bands pattern of antibody resistantigen coded by pol gene and the positive rate of P31 antibody has significant difference between the people infected by different transmission mechanism, P < 0.01;The positive rate of P66 and P24 antibody of people less than orequal to 40 years was significant greater than thatof people older than 40 years, P < 0.05;The WB bands pattern of antibody resistantigen coded by polgene and the positive rate of P 66 antibody has significant differnce among people from various regions.

  Conclusion   HIV-1 antibody WB bands pattern is not significant diffferent among people who are different sexor age, butitis different among people who are infected through differenttrans mission mechanism or from various region; the production of some antibody resistantigen coded by HIV-1 polor gaggene is different among people who are infected through different transmission mechanism or from various region or differentage.
