Clinical efficacy evaluation and economic analysis of regulating-yinyang moxibustion therapy for primary dysmenorrhea of cold induced blood stasis: a randomized controlled trial
To observe the clinical therapeutic effect and effect mechanism of regulating-
yinyang
moxibustion therapy for primary dysmenorrhea (PD) of cold induced blood stasis
and conduct cost-effectiveness analysis.
Methods
2
Sixty-six patients with PD of cold induced blood stasis were randomly divided into an observation group (33 cases
1 case dropped out) and a control group (33 cases
3 cases dropped out). The patients in the observation group received regulating-
yinyang
moxibustion therapy. Centered at Mingmen (GV4) and Guanyuan (CV4)
moxibustion therapy for warming
yang
and benefiting kidney and for warming kidney and uterus was operated within an 8 cm to 10 cm radius separately. Moxibustion therapy for warming
yang
an
d benefiting kidney was delivered 10 days before menstruation (60 min)
and that for warming kidney and uterus was performed 2 days before menstruation (40 min). One course of regulating-
yinyang
moxibustion therapy consisted of 1 operation for warming
yang
and benefiting kidney and 1 for warming kidney and uterus
and the treatment for 3 menstrual cycles was required. In the control group
gentle moxibustion therapy was operated at Guanyuan (CV4)
Shenque(CV8)
and bilateral Sanyinjiao (SP6)
for 20 min at each acupoint. The intervention began 10 days before menstruation
once every other day; 1 course of treatment consisted of 5 interventions
and the treatment for 3 menstrual cycles was required.Before and after treatment
as well as in follow-up for 3 menstrual cycles after treatment
the scores of visual analogue scale(VAS) for pain
Cox menstrual symptom scale (CMSS)
and traditional Chinese medicine (TCM) clinical syndromes were observed in the two groups. Before and after treatment
the contents of nerve growth factor (NGF) and prostaglandin F2α(PGF2α) in serum were detected. After treatment
the clinical therapeutic effect was compared
the cost-effectiveness analysis performed
and the sensitivity analysis conducted to verify the reliability of the results in the two groups.
Results
2
After treatment and in follow-up
the VAS scores for pain were reduced in comparison with those before treatment in each group (
P
<
0.05)
and the scores in the observation group were lower than those of the control group (
P
<
0.05). The scores for the severity and duration in CMSS were lower than those before treatment in the observation group (
P
<
0.05)
and lower when compared with those in the control group (
P
<
0.05). When compared with the score before treatment
the TCM syndrome scores in the observation group were reduced after treatment and in follow-up (
P
<
0.05)
and the score in the control group was lower after treatment (
P
<
0.05). In follow-up
the TCM syndrome score in the observation group was lower than that in the control group (
P
<
0.05). After treatment
the serum contents of NGF and PGF2α decreased in comparison with those before treatment (
P
<
0.05)
and the contents in the observation group were lower than those in the control group (
P
<
0.05).After treatment
the total effective rate was 81.3% (26/32) in the observation group and was 73.3% (22/30) in the control group
without statistical significance (
P
>
0.05). The cost-effectiveness analysis showed that the cost-effectiveness ratio(CER) in the observation group was lower than that in the control group. The sensitivity analysis found that there was no significant fluctuation of CER in either group.
Conclusion
2
Regulating-
yinyang
moxibustion therapy effectively alleviates pain and TCM syndromes in patients with PD of cold induced blood stasis
which may be related to the decrease of the contents of NGF and PGF2α in serum. This therapy shows its advantages in terms of health economics compared with the conventional gentle moxibustion therapy.
