480 women clinically diagnosed of primary dysmenorrhea will be enrolled from nationwide multi-centers. Blood samples were collected from 480 patients before and after treatment (1 experimental group, 3 control groups, treatment cycle of 3 menstrual cycles, follow-up cycle of 5 menstrual cycles), Metabonomics study, and integration of clinical sample information (Serum biochemical indicators, imaging indicators, etc.), through bioinformatics to establish a comprehensive biomarker index system for the evaluation of the efficacy of traditional Chinese medicine, Western medicine and Low-level Light Therapy instrument Methods for the treatment of primary dysmenorrhea and its therapeutic basis.
To observe the clinical efficacy and safety of three methods for the treatment of primary dysmenorrhea. Establish an integrated biomarker index system for the evaluation of the efficacy of traditional Chinese medicine, western medicine and Low-level Light Therapy for the treatment of primary dysmenorrhea, and further explore the mechanism and therapeutic material basis of the three treatment methods for the treatment of primary dysmenorrhea
