title: [Effect of xiongshao capsule on vascular remodeling in porcine coronary balloon injury model].
abstract: OBJECTIVE
  To study the effect of Xiongshao Capsule (XS) on vascular remodeling in porcine coronary balloon injury model.
  
  
  METHODS
  Restenosis model was established by oversized balloon injury at mid-region of the left anterior descending coronary artery. The effect of drugs on late lumen loss and vascular remodeling was evaluated with quantitative histological method by combining results from histopathological analysis and coronary arteriography.
  
  
  RESULTS
  Vascular remodeling explained (59 +/- 20)% of late lumen loss. All drugs significantly reduced late lumen loss 4 weeks after balloon injury (P < 0.05 or 0.01). Both low-dose and high-dose XS markedly reduced late lumen loss resulting from vascular remodeling, as compared with the control group (P < 0.05 and P < 0.01 respectively).
  
  
  CONCLUSIONS
  Vascular remodeling played an important role in late lumen stenosis after balloon injury of coronary artery. XS could significantly inhibit pathological vascular remodeling after balloon injury, thus reduce late lumen loss and prevent restenosis.
