Objective To assess polymerase chain reaction(PCR)combined with restriction fragment length polymorphism(RFLP)and gene sequencing technologies in the detection and typing of HPV DNA.Methods Tissue specimens were collected from skin diseases and venereal disease in perianal or genitals.PCR was performed with HPV DNA general primers(MY09/11)in tissue samples. Positive fragments of HPV DNA were purified and digested by restriction enzymes.The digested fragments were typed by po]yacrylamide gel electrophoresis(PAGE).The Resultswere verified by direct sequencing.Results In 50 clinical samples there were 35 HPV DNA positive,including 26 from patients with condyloma acuminatum,8 from patients with bowenoid papulosis,and 1 from patients with squamous cell carcinoma.In HPV DNA positive samples,19 were HPV6,3 were HPV11,8 were HPV16,4 were HPV6 and HPV 11,and I was HPV62.Sequencing Resultswere in accordance with the PCR-RFLP Results .Conclusion PCRRFLP method is effective in the detection and typing of HPV DNA.
