ABSTRACT
<p><b>OBJECTIVE</b>To detect and type human papilloma virus (HPV) in the warts of oral mucosa from HIV-positive patients, and better understand the biological characters of these oral warts.</p><p><b>METHODS</b>Polymerase chain reaction (PCR) was used to detect and type HPV infection by consensus HPV primers Gp5+/Gp6+ and specific HPV primers (HPV6/11, 16, 18, 31, 33) in 34 cases of oral mucosa warts from HIV-positive patients.</p><p><b>RESULTS</b>The HPV infection rate was 88.2% by consensus HPV primers Gp5+/Gp6+; the HPV infection rate of HPV6/11, 16, 18, 31 was respectively 47.06%, 11.67%; 2.94%, and 5.88% by specific HPV primers.</p><p><b>CONCLUSION</b>Most lesions of oral warts from HIV-positive patients are associated with the infection of HPV. The low risk HPV6/11 infection is more common than the high risk HPV16, 18, 31.</p>

Objective: To detect P53 and Ki-67 protein,human papill om a virus (HPV),cytomegalovirus(CMV) and Epstein-Barr virus(EBV)in the warts of o ral mucosa from HIV-positive patients.Methods: The expression P53 and Ki-67 protein,HPV,EBV and CMV were detected by immunohistochemistry and PCR in 34 cases of oral mucosa warts from HIV-positve patients,33 cases of oral epithelia dysplasia and 45 cases of oral squamous cell carcinoma. Results:(1)The expression of P53 and Ki-67 protein in the cases of oral mucosa warts from HIV-positive patients were 23%and 76% re spectively,lower than those in oral suquamous cell carcinoma lesions from non- HIV individuals(62.8% and 97.8% respectively,P0.05).(2)The HPV infection in the warts of oral mucosa from HIV -positive patients was 88.2%,much higher than in oral suquamous cell carcinoma lesions (35.6%) and in dysplastic lesions (9.1%) from non-HIV individuals(P
