Abstract:
Background The pathogenesis of pterygium has been in the study.Relative molecular biology study showed that pterygium is a tumor-like lesion,and based on overseas literatures,human papillomavirus (HPV) is positively expressed in 100％ patients with pterygium in some region.However,if this result is suitable for Chinese patients is unclear.Objective This study was to identify the role of human HPV in the pathogenesis of pterygia in Wuxi area.Methods Forty-eight pterygium specimens including 7 recurrent pterygia and 41 primary pterygia were collected during the operation,and these patients were from Wuxi area.Two cervical carcinoma specimens and 2 conjunctiva specimens from normal donors were obtained as positive control and negative control respectively.The fluorescent quantitative polymerase chain reaction (FQ-PCR) was used to detect HPV DNA of specimens.Results The amplified curves of HPV 6,11 of pterygium specimens,cervical carcinoma specimens and normal specimens were all below the positive quality control curve,but the amplified curves of HPV16,18 were above the quality control curve in cervical carcinoma specimens; while those of pterygium specimens and normal conjunctival specimens were all below the quality control curve.HPV16/18 was identified in 2 cervical carcinoma specimens,but no HPV6/11 was detected in 2 cervical carcinoma specimens.However,HPV DNA expression in primary and recurrent pterygias were absent.Conclusions According to these results,HPV is not the primary cause for the pathogenesis of pterygium in Wuxi region.
