title: [Pathological basis of qi-deficiency and blood stasis syndrome in patients with non-small cell lung cancer viewing from tumor metastasis related factors].
abstract: OBJECTIVE
  To observe the expressions of tumor metastasis related factors (TMRF) in peripheral blood of patients with non-small cell lung cancer (NSCLC) for exploring the molecular mechanism for genesis of qi-deficiency and blood stasis (QDBS) syndrome in patients.
  
  
  METHODS
  Eighty selected NSCLC patients of stage II B/III were differentiated into the QDBS group and the non-QDBS group according to the Chinese medicine syndrome differentiation criteria, 40 in each group. The serum levels of vascular endothelial growth factor (VEGF), endostatin (ES) and soluble intercellular adhesive molecule-1 (slCAM-1) in patients were detected by ELISA, and the expression of adhesive molecule CD44 in peripheral blood was determined using flow cytometry.
  
  
  RESULTS
  Serum levels of VEGF (1002.78 +/- 312.08 ng/L), ES (120.88 +/- 20.00 microg/L), slCAM-1 (531.78 +/- 213.37 microg/L) and CD44 (136.65 +/- 29.60) were significantly higher in patients of QDBS group than in patients of non-QDBS group (653.18 +/- 318.99 ng/L, 98.29 +/- 23.92 microg/L, 409.36 +/- 167.65 microg/L and 98.46 +/- 20.64, respectively, P<0.01).
  
  
  CONCLUSIONS
  Objective inner links are found between the QDBS syndrome and TMRF in NSCLC patients; serum levels of VEGF, ES, slCAM-1 and CD44 can be served as the microcosmic basis for QDBS syndrome differentiation.
