title: [Detection of EBV-DNA, EBNA2 and LMP-1 in tumor tissues of han and uygur patients with nasopharyngeal carcinoma in Xinjiang].
abstract: OBJECTIVE
  To investigate the possible differences of human nasopharyngeal carcinogenesis between Han and Uygur patients in xinjiang.
  
  
  METHODS
  Detection of EBV-DNA, EBNA2 and LMP-1 in tumor tissues of 73 patients (Han 41, uygur 32) with nasopharyngeal carcinoma (NPC) were performed by PCR and immunohistochemistry.
  
  
  RESULTS
  Tho positive rate of EBV-DNA, EBNA2 expression was 48.2%(20/41), 43.9% (18/41) in Han and 59.3%(19/32), 43.7%(14/32) in Uygur respectively, no significant difference was found (P > 0.05). Expression of LMP-1 in NPC, in both positive and negative EBV-DNA specimens, was higher in Uygur (78.9%) than that in Han (40%) (P < 0.05),
  
  
  CONCLUSIONS
  The EBV infection may involve in nasopharyngeal carcinogenesis in xinjiang; the LMP-1 of EBV could be a more critical factor in malignant transformation of normal nasopharyngeal epithelium in uygur people than in han Chinese.
