title: [Effects of shuanglong pill on mRNA expression of platelet-derived growth factor A and monocyte chemoattractant protein-1 mRNA].
abstract: OBJECTIVE
  To explore the molecular mechanism of Shuanglong Pill (SLP) in intervening atherosclerosis, mainly the effect of SLP on the mRNA expression of the platelet-derived growth factor-A (PDGF-A) and the monocyte chemoattractant protein-1 (MCP-1).
  
  
  METHODS
  Using the hyperlipoprotein serum (HLS) of cultured rabbits' aortic smooth muscle cell (SMC) to build the atherosclerotic cell model, and medicated serum acting on the cell model by serum pharmacologic method. The effect of SLP medicated serum on the level of PDGF-A, MCP-1 mRNA expression were observed and analysed by means of reverse transcriptase-polymerase chain reaction assay.
  
  
  RESULTS
  It was found that HLS stimulated mRNA expression of the PDGF-A and the MCP-1, but the medicated serum of SLP lowered their expression level.
  
  
  CONCLUSIONS
  SLP could inhibit the function of cellular auto-secreting growth factor, it is one of the possible pharmacologic mechanism in intervening atherosclerosis.
