title: [Systematic review of randomized controlled trials on preventing and treating restenosis after percutaneous coronary intervention with Chinese medicine].
abstract: OBJECTIVE
  To evaluate the randomized controlled trials on preventing and treating restenosis after percutaneous coronary intervention (PCI) with Chinese medicine adopting the principle of evidence-based medicine (EBM).
  
  
  METHODS
  Pertinent literatures were retrieved roundly, and scored depending on Jadad Quality Scale. Meta-analysis was applied on the total effect of outcomes reported using RevMan 4. 2 software. Moreover, the sensitivity was analyzed, the publication bias was identified with funnel-plot and the adverse reaction of medicine was reported.
  
  
  RESULTS
  Among the 17 literatures met the inclusion criteria, only two double-blinded trials were appraised as high quality. The analysis on the recurrence rates of restenosis post-PCI and angina pectoris in patients treated with Chinese medicine illustrated that the rates in the treatment group were all lower than those in the control group with statistical significance (P < 0.01). Sensitivity analysis revealed a relatively stable result of the evaluation. Funnel-plot displayed an asymmetrical figure, indicating the possible existence of publication bias.
  
  
  CONCLUSIONS
  TCM has definite therapeutic effect on preventing and treating restenosis after PCI and reducing the recurrence rate of angina pectoris in patients.
