[Research progress and reflection on mechanisms of acupuncture against primary dysmenorrhea].

Research articles on the mechanisms of acupuncture in the treatment of dysmenorrhea model in rats were retrieved from PubMed and China National Knowledge Infrastructure (CNKI). As revealed by the analysis, the underlying mechanisms were mainly related to the regulation of endocrine system and neurotransmitters, the modulation of immunoinflammatory responses, the improvement of uterine microcirculation, and reduction of oxidative stress. In the future, research should be carried out to explore the mechanism of acupuncture in relieving dysmenorrhea via acupoints and the specific mechanism of classical acupoints, so as to enrich the multi-pathway mechanisms of acupuncture in treating dysmenorrhea and provide more scientific basis for optimizing clinical modalities for primary dysmenorrhea treatment by acupuncture.
