title: Effect of Xuebijing injection on peripheral T-lymphocyte subpopulations in patients with severe trauma.
abstract: OBJECTIVE
  To investigate the effect and clinical significance of Xuebijing injection on peripheral T-lymphocyte subpopulations in patients with severe trauma.
  
  
  METHODS
  Thirty-three patients with severe trauma were randomly divided into a control group (n=16) and a treatment group (n=17). The patients of two groups were all treated conventionally, and the only difference was that Xuebijing injection was given to patients of the treatment group. The CD4+ and CD8+ subpopulations of T-lymphocyte in the peripheral blood were detected respectively on admission, 3rd and 5th days after trauma by double antibody labeling and flow cytometry.
  
  
  RESULTS
  The CD4+ T-lymphocytes and CD4+/CD8+ ratio of peripheral blood in patients with severe trauma decreased markedly on the 3rd and 5th days after trauma. Furthermore, compared with control group, the peripheral CD4+ T-lymphocytes and CD4+/CD8+ ratio of treatment group renewed obviously on the 5th day after trauma, and showed statistical differences (P<0.05).
  
  
  CONCLUSIONS
  In the treatment of patients with severe trauma, the early use of Xuebijing injection is effective in correcting disorder or suppression of T-lymphocyte subpopulations regulating network, and promoting a more balanced profile of immunologic function.
