title: [The protein expression difference of transforming growth factor beta1, matrix metalloproteinases 1,7,9 and tissue inhibitors of matrix metalloproteinases-1 between chronic rhinosinusitis, nasal polyps and normal mucosa tissues].
abstract: OBJECTIVE
  To compare the expression difference of transforming growth factor beta1 (TGF-beta1), matrix metalloproteinases1,7,9 (MMP-1,7,9 ) and tissue inhibitors of matrix metalloproteinases-1 (TIMP-1) protein among the chronic rhinosinusitis tissues, nasal polyps tissues and normal nasal mucosa tissues.
  
  
  METHODS
  The protein expression of TGF-beta1, MMP-1, MMP-7, MMP-9 and TIMP-1 in chronic rhinosinusitis tissues from 22 patients, in nasal polyps tissues from 21 patients and in inferior turbinate tissues from 15 patients underwent nasal septum operation was detected by enzyme-linked immunosorbent assay (ELISA).
  
  
  RESULTS
  (1) In chronic rhinosinusitis and nasal polyps tissues, compared with controls, the expression of TGF-beta1, MMP-7, MMP-9, TIMP-1 protein was significant increased (P < 0.05); (2) The expression of TGF-beta1 and TIMP-1 in chronic rhinosinusitis tissues was significant increased versus that in nasal polyps tissues (P < 0.05); (3) Concentration of MMP-7 protein in nasal polyps tissues was found significant higher than that in chronic rhinosinusitis tissues (P < 0.01).
  
  
  CONCLUSIONS
  Different TGF-beta1, MMP-7, TIMP-1 protein level in chronic rhinosinusitis and nasal polyps tissues might be the molecular basis of the different histopathological character of chronic rhinosinusitis and nasal polyp tissues.
