Methods Ten mature Wistar rats were divided into normal control group (5 rats) and adenovirus (E1, E3-Deleted and carried math1 and enhanced green fluorescent protein report gene, Ad-Math1-EGFP) scala vestibuli transfer group (5 rats). Right ears of the Ad-Math1-EGFP transfering group rats were deliveried 5μl Ad-Math1-EGFP (physical tite 2.1×10^11v.p./ml) into cochleas through the way of drilling scala vestibuli of cochlear basal turn. As a control, the normal group received nothing to inner ear. In order to estimate functional condition of vestibule and cochlea, the click-evoked potentials on the surface of the cervical dura mater, auditory brain stem response and swimming time were recorded in all rats at 7 days after treatment, and then histologic and morphologic observation were carried out after animals were sacrificed. Results All animals' morphologic observation showed that inner ear hair cells were normal after transfer.

The cutoff value of E2/E6, used to distinguish the pure episomal form from a mixed form of episomal and integrated HPV16 DNA, was 0.81 in the multiplex real-time PCR test. c） HPV16 existed as episomes in most of the CIN Ⅰ lesions, and 42.9% of them had mixed episomal/integrated HPV16. The integrated form of HPV16 constituted the majority in most of the CIN Ⅱand CIN Ⅲ cases. In squamous cervical carcinomas, the HPV16 was mostly integrated into the host chromosome. d） The rate of HPV16 integration was associated with the degree of cervical lesions and the rate increased with the progression of cervical disease, e） The rate of pure integrated HPV16 in stage Ⅱ and Ⅲ（88%） was higher than that in stage Ⅰ（33.3%）. Conclusions: a） Multiplex real-time PCR is a rapid and sensitive method for detection of the integration state of HPV16 DNA. b） The integration of HPV16 DNA is a very early event in the development of cervical cancer and may act as an activation mechanism for progression from preinvasive to invasive cervical cancer, c） The pure integrated HPV16 in cervical cancer may be a useful prognostic indicator.
