title: [Effects of acupuncture combined with medicine on expression of matrix metalloproteinase-2 in the rat of endometriosis].
abstract: OBJECTIVE
  To probe into an effective method for treatment of endometriosis (EMs) and the mechanism.
  
  
  METHODS
  Rat EMs model was established and they were randomly divided into a model group, an acup-moxibustion group, a TCM group, an acupuncture and medicine group, with a control group set. The acup-moxibustion group were treated with electroacupuncture at "Xuehai (SP 10)", "Sanyinjiao (SP 6)" and moxibustion at "Guanyuan (CV 4)"; the TCM group were treated with stomach perfusion of modified Mojie Tablet in normal saline; the acupuncture and medicine group were treated with the above two methods; both the control group and the model group were bound and treated with stomach perfusion of saline. After treatment of 35 days, the greatest diameter of the ectopic tissue was measured in the rats, pathological observation of the ectopic tissue was made and matrix metalloproteinase-2 (MMP-2) expression in the ectopic tissue was determined.
  
  
  RESULTS
  The greatest diameter of ectopic tissue and MMP-2 expression in the ectopic tissue in the acupuncture and medicine group were significantly lower than those in the model group, the acup-moxibustion group and the TCM group (P < 0.05); and the ectopic endometrium trended to atrophy, and with necrosis of some epithelial cells.
  
  
  CONCLUSIONS
  Combination of acupuncture with medicine has a better therapeutic effect on endometriosis and down-regulates the abnormal increase of MMP-2 level to inhibit the invasion of ectopic tissue to extracellular matrix, so as to reduce the ectopic tissue, hence cure of endometriosis.
