title: Relationship between various Chinese medicine types and T-cell subsets in patients with ulcerative colitis.
abstract: OBJECTIVE
  To investigate the relationship between various Chinese medicine (CM) types and T-cell subsets (CD4(+) and CD8(+)) in the colonic mucous membranes of patients with ulcerative colitis (UC).
  
  
  METHODS
  Fifty UC patients were enrolled, after differentiation into four types by CM syndromes, i.e., the internal heat-damp accumulation type (IHDA), the qi-stagnancy with blood stasis type (QSBS), the Pi-Shen yang-deficiency type (PSYD) and the yin-blood deficiency type (YBD). From every patient, 3-5 pieces of intestinal mucous membrane tissues were taken through colonoscopy to determine the levels of the T-cell subsets (CD4(+) and CD8(+)) using immunohistochemical method. The results were compared with those in the normal control.
  
  
  RESULTS
  The level of CD8(+)increased and the ratio of CD4(+)/CD8(+)decreased mainly in colonic mucous membranous tissues in UC patients. The level of CD4(+)decreased significantly in IHDA types (P<0.01), but decreased only slightly in the PSYD, QSBS and YBD types. CD8(+)increased significantly in the IHDA types (P<0.01), but only slightly in the other three types.
  
  
  CONCLUSIONS
  The IHDA types of UC are closely related with T-cell subsets. The difference of T-cell subsets in various IHDA types of UC patients has provided a theoretical basis for syndrome differentiation in the CM typing of UC.
