title: [Effect of massage on hemodynamics parameters of uterine artery and serum prostaglandin in treating patients with primary dysmenorrhea].
abstract: OBJECTIVE
  To observe the curative effect of massage in the treatment of primary dysmenorrhea (PD), and its effect on hemodynamics parameters of uterine artery and serum prostaglandins.
  
  
  METHODS
  60 PD patients were randomly assigned to the massage group and the control group, 30 in each. Patients in the massage group received massage, while those in the control group orally took ibuprofen sustained release capsule, both for three menstrual cycles. The pain degree was assessed using visual analogue scale (VAS). The hemodynamics parameters of uterine artery [including pulsatility index (PI), resistance index (RI), systolic to diastolic peak ratio (S/D)], the serum levels of prostaglandin F2alpha (PGF2alpha) and PGE2 in the menstruation were detected in the two groups before and after treatment.
  
  
  RESULTS
  There was no statistical difference in each index before treatment between the two groups (P>0.05). Compared with the control group after treatment, the scores of VAS (mm, 33. 17+/-7.93 vs 63.53+/-9.48), PI (2.18+/-0.18 vs 2.74+/-0.23), RI (0.67+/-0.09 vs 0. 86+/-0.27), S/D (5.44+/-0.47 vs 7.56+/-0.28), and serum PGF2a level (ng/L, 28. 10+/-2.41 vs 37.68+/-2.16) were lower and serum PGE, level (ng/L, 29.82+/-2.13 vs 26.43+/-1.42) higher in the massage group, showing statistical difference (P<0.05, P<0.01).
  
  
  CONCLUSIONS
  Massage had favorable therapeutic effect on PD. Its effect might be achieved through improving the blood circulation of uterus, adjusting the abnormal levels of PGF2a and PGE2, thus exerting pain relief effect.
