ABSTRACT
<p><b>OBJECTIVE</b>To investigate the association between HPV16 infection, E6/E7 variations and the cervical lesions.</p><p><b>METHODS</b>HPV subtypes were detected by using flow-through hybridization technique, E6/E7 gene was extracted from cervical lesions in 80 patients with HPV16 infection, PCR amplified, cloned into plasmid pMD18-T and sequenced.</p><p><b>RESULTS</b>HPV 16 was the most common type which accounted for 33.3% (154/463), the HPV16 infection rates increased with the severity of cervical lesions (P < 0.05). Totally in 72 cases the complete E6 and E7 regions were successfully sequenced, the DNA mutation rate of E6/E7 was 88.9% (64/72). A mutation, E6-D32E (T96G) coincided with a specific type of E7 mutation, N29S (A86G). D32E/N29S mutation rate was 38.9% (28/72), the detection rate increased with the severity of cervical lesions (P < 0.05).</p><p><b>CONCLUSION</b>HPV 16 was the most common type in women with cervical lesions in Beijing, D32E/N29S variant associated with the cervical lesions.</p>
