title: [Research progress of platelet-rich plasma in treating chronic tissue lesions].
abstract: OBJECTIVE
  To introduce the effect of platelet-rich plasma (PRP) in the treatment of chronic tissue lesions.
  
  
  METHODS
  The latest research papers concerning the relevant subject were reviewed and analyzed.
  
  
  RESULTS
  In PRP, the platelets and cytokines, the interaction of them in the same proportion as they were in the body fluid, played promoting role in repairing the chronic damage of tissues. However, there was still way to go before PRP was applied for clinical use in a wider range.
  
  
  CONCLUSIONS
  PRP has quite a bright outlook in the treatment of chronic tissue lesions.
