title: [Dracorhodin perchlorate inhibit high glucose-induced connective tissue growth factor formation in human mesangial cells].
abstract: OBJECTIVE
  To study the effect of dracorhodin perchlorate on high glucose-induced connective tissue growth factor (CTGF) expression in human mesangial cells (HMC), and its mechanism of prevention and treatment on renal fibrosis in diabetic nephropathy (DN).
  
  
  METHODS
  The HMC were divided into low glucose group (LG group, 5.5 mmol x L(-1) D-glucose), high glucose group (HG Group 25 mmol x L(-1) D-glucose), each group was located with dracorhodin perchlorate (7. 5 micromol x L(-1)) as comparison, and was examined at 24, 48 h. The expression of CTGF mRNA was assessed by semi quantatiue RT-PCR, and the expression of CTGF protein was assessed by Western blot.
  
  
  RESULTS
  Compared to HG group, the expression of CTGF mRNA and protein were reduced in LG group after stimulating 24, 48 hours (P < 0.01). Compared to HG group, the expression of CTGF mRNA and protein were reduced in HG group by added with dracorhodin perchlorate after stimulating 24, 48 hours (P < 0.01).
  
  
  CONCLUSIONS
  Dracorhodin perchlorate can inhibit high glucose-induced connective tissue growth factor expression in human mesangial cells, and this may be its mechanism of prevention and treatment on renal fibrosis in diabetic nephropathy (DN).
