title: [Effect of Leonurus Heterophyllus Sweet on tissue factor transcription and expression in human umbilical vein endothelial cells in vitro].
abstract: OBJECTIVE
  To investigate the effect of Leonurus Heterophyllus Sweet, (LHS) on tissue factor (TF) transcription and expression induced by thrombin in human umbilical vein endothelial cells (HUVECs).
  
  
  METHODS
  HUVECs were incubated with different concentrations of LHS and the TF mRNA expression was detected by reverse transcript-polymerase chain reaction (RT-PCR).
  
  
  RESULTS
  LHS treatment of HUVECs at different concentrations and for different times resulted in significant differences in TF expression (Plt;0.01). The transcription of TF in LHS-treated cells was significantly different from that of the blank control group (Plt;0.01).
  
  
  CONCLUSIONS
  LHS can decrease the expression of TF and intervene with TF transcription in HUVECs in vitro.
