Research on the clinical effects of new ventral moxibustion box in treating primary dysmenorrhea of the type of congealing cold blood stasis

Objective To observe the clinical effects of new ventral moxibustion box in treating primary dysmenorrhea of the type of congealing cold blood stasis. Methods 158 patients of primary dysmenorrhea of the type of congealing cold blood stasis were randomized into new ventral moxibustion box treatment group（56 patients）,traditional moxibustion box treatment group（52patients）and control group （50patients）. The control group was treated by conventional treatment, and the other two groups were treated by new ventral moxibustion box and traditional moxibustion box. The therapeutic effects were compared after treatment. Results After treatment,the cure rate of new ventral moxibustion box treatment group was 35.71%, the cure rate of traditional moxibustion box treatment group are 34.61%,both were better than18.00%of the control group with statistical significance（χ^2=4.17, 3.62, P〈0.05）. The total effective rate of new ventral moxibustion box treatment group was 92.86%, the total effective rate of traditional moxibustion box treatment group was 90.38%,both were better than 70.00%of the control group with statistical significance（χ^2=9.38, 6.72, P〈0.01）. The safety rate of new ventral moxibustion box treatment group was better than the control group（χ^2=5.91, P〈0.05）. Conclusion The new ventral moxibustion box can not only improve the curative effect of primary dysmenorrhea of the type of congealing cold blood stasis,but also can improve the safety rate in treating primary dysmenorrhea.
