title: [Human papillomavirus type 16 E5 sequence evolution analysis].
abstract: OBJECTIVE
  To investigate the distribution of HPV 16 variants in Han women patients without Cervical intraepithelial neoplasia in the diagnosis and treatment center for cervical disease, department of Obstetrics and Gynecology in China-Japan friendship hospital with HPV 16 E5 sequence phylogenetic analysis.
  
  
  METHODS
  PCR amplification of HPV 16 E5 sequences and sequenced. The association between variations types and different cervical lesions was analyzed.
  
  
  RESULTS
  In this research, We first found that variant classification based on HPV 16 E5 DNA sequence (236 bp) alone had high rate of accuracy. In addition, for the first time, our research revealed that single-4075T can distinguished the As variant from all other variants.
  
  
  CONCLUSIONS
  If E5 sequence was used for phylogenetic analysis, it will greatly reduce the experimental costs and improve efficiency and cost-effectiveness. For the first time, our research revealed that single 4075T can distinguished the As variant from all other variants.
