title: [T cell immunity analysis in children with obstructive sleep apnea syndrome].
abstract: OBJECTIVE
  To probe into the possible impact on T cell immunity in children with obstructive sleep apnea syndrome (OSAS).
  
  
  METHODS
  Lymphocytes in peripheral blood vessel of children with OSAS vs normal controls were checked by APAAP method and analyzed statistically.
  
  
  RESULTS
  The comparison with the controls showed that CD3+ had no significant difference (P>0.05), CD4+, CD4+/CD8+ were significantly lower, CD8+ was significantly higher in children with OSAS (P<0.01), and the analysis of the LSaO2 and period of history showed that the lower the LSaO2, and the longer the period of history, the more effect to CD4+, CD8+, CD3+/CD8+ (P<0.05).
  
  
  CONCLUSIONS
  T cell immunity are impaired in children with OSAS.
