title: [Diagnostic value of assay of brain natriuretic peptide in patients with sepsis of blood-stasis syndrome].
abstract: OBJECTIVE
  To explore the diagnostic value of brain natriuretic peptide (BNP) level in patients with sepsis of blood-stasis syndrome.
  
  
  METHODS
  The prospective method of clinical diagnostic test and evaluation principles of diagnostic test were applied. One hundred and seventy-four patients with sepsis were divided into two groups: blood-stasis syndrome group and non blood-stasis syndrome group. The levels of serum BNP in two groups were detected.
  
  
  RESULTS
  The level of BNP in sepsis patients was related to blood-stasis syndrome (P<0.01). BNP cut-off level was 150 ng/L, sensitivity was 85.3%, specificity was 81%, the maximum value of Youden index was 0.663, and the area under the receiver operating characteristic curve (ROC) value was (0.886+/-0.025).
  
  
  CONCLUSIONS
  BNP can be used as an objective index of blood-stasis syndrome diagnosis for sepsis, and BNP with boundary value of 150 ng/L is an optimal biological index.
