ABSTRACT
Objective::To explore the effect of Wenjingtang on the levels of serum platelet activating factor (PAF) and β-endorphins in primary dysmenorrhea patients with cold stagnation and blood stasis syndrome. Method::The 120 cases of dysmenorrhea treated at Second Affiliated Hospital, Heilongjiang University of Chinese Medicine from March 2016 to December 2017 were selected as the observation subjects, and divided into control group and observation group according to the random number table method, with 60 cases in each group. The control group was treated with ibuprofen capsules, while the observation group was treated with Wenjingtang and ibuprofen capsules. Dysmenorrhea symptom scores, clinical efficacy, recurrence condition and serum levels of platelet activating factor and β-endorphins were compared before and after treatment. Result::After treatment, the dysmenorrhea symptom scores decreased significantly in both groups, and the scores of patients in observation group were lower than those in control group (P<0.05). After treatment, the total efficiency in observation group was 95%, which was significantly higher than 83.33% in control group (P<0.05). The level of serum PAF decreased significantly in two groups, and the serum PAF in observation group was significantly decreased compared with control group (P<0.05). The level of serum beta-endorphins in observation group was significantly higher than that of control group (P<0.05). After half a year, the recurrence rate of the observation group was 5%, which was significantly lower than 30% of control group (χ2=12.987, P<0.01). Conclusion::Wenjingtang contributes to the reduction of dysmenorrhea symptoms scores in primary dysmenorrhea patients with cold stagnation and blood stasis syndrome, and can improve the clinical efficacy, reduce the serum PAF level and increase the concentration of β-endorphins, reduce the recurrence rate, improve the quality of life of patients, and it is worth promoting.
