title: [Application of Van-Clear and xylene in the detection of cervical hTERC gene by fluorescence in situ hybridization].
abstract: OBJECTIVE
  To observe the effect of Van-Clear on vamplification of human telomerase RNA component (hTERC) gene in cervical tissues by fluorescence in situ hybridization, and to determine the potential for Van-Clear to replace xylene.
  
  
  METHODS
  A total of 278 specimens of cervix uteri were collected from inpatients of Department of Gynaecology in Boai Hospital of Zhongshan from January to February, 2015, with 81 cases of normal specimens, 68 cases of cervical intraepithelial neoplasia (CIN) I, 57cases of CIN2, 42 cases of CIN3 and 30 cases of cervical invasive cancer. Double samples were collected from the same region. Fluorescence in situ hybridization was applied to detect the changes in the amplification of hTERC gene in 2 groups of specimens from the cervical biopsy.
  
  
  RESULTS
  Differences in the positive expression rate of hTERC gene between the 2 groups of cervical lesions at all levels were not statistically significant (P>0.05).
  
  
  CONCLUSIONS
  There is no significant difference in the positive rate of hTERC gene expression between the slices made by Van-clear and xylene. As an environmental-friend product, Van-Clear possesses certain value in detection of cervical hTERC gene by fluorescence in situ hybridization.
