title: [Alternation and significance of CD4(+)CD45RA(+) and CD4(+)CD45RO(+) T cells in peripheral blood of colorectal cancer patients].
abstract: OBJECTIVE
  To investigate the alternation and significance of CD4(+)CD45RA(+) T cells and CD4(+)CD45RO(+) T cells in peripheral blood of colorectal cancer patients.
  
  
  METHODS
  The expression of CD4(+) T cells, CD4(+)CD45RA(+) T cells and CD4(+)CD45RO(+) T cells in peripheral blood of 60 colorectal cancer patients were detected with flow cytometry pre-operatively and 1, 3 months post-operatively, compared with those of 10 healthy persons.
  
  
  RESULTS
  CD4(+) T cells expression of colorectal cancer patients was the same as the healthy persons. The proportion of CD4(+)CD45RO(+) T cells of colorectal cancer patients was higher, which descended post-operatively, especially in Dukes A and B patients, while CD4(+)CD45RA(+) T cells showed the opposite findings.
  
  
  CONCLUSIONS
  CD4(+)CD45RA(+) T cells and CD4(+)CD45RO(+) T cells, playing an important immune effect in colorectal cancer patients, is closely related to stage and prognosis.
