Objective: To observe the meridian-acupoint reactions of foot three yin meridians in primary dysmenorrhea(PD) and secondary dysmenorrhea(SD) patients, so as to summarize the rules of meridian-acupoint reaction and acupoints selection., Methods: Thirty-five patients with PD (PD group), 34 patients with SD (SD group) and 35 healthy subjects (healthy group) were recruited. The compression method was used to examine the lower leg segment of the foot three yin meridians. Positive reactions(palpable skin changes, including cords, nodules, depressions) and tenderness of meridians and acupoints were recorded. The visual analogue scale (VAS) was used to evaluate the tenderness severity of acupoints., Results: Compared with the healthy group, the probability of positive reactions and tenderness in foot three yin meridians were higher in PD and SD groups ( P <0.01, P <0.05). Compared with the PD group, the probability of positive reactions in Spleen and Liver Meridians were higher in the SD group, with higher probability of tenderness in Liver Meridian( P <0.05). The probability of positive reactions and tenderness in the Spleen Meridian of PD and SD groups was significantly higher than that in the Kidney Meridian ( P <0.01), while the probability of tenderness in the Spleen Meridian of the PD group was significantly higher than that in the Liver Meridian ( P <0.05). Positive reactions and tenderness were concentrated at Yinlingquan (SP9), Diji (SP8) and Sanyinjiao (SP6) of Spleen Meridian and Xiguan (LR7) and Ligou (LR5) in Liver Meridian of PD and SD groups. In comparison with the PD group, the probability of positive reactions, tenderness and VAS score of SP8 and LR5 of the SD group were higher ( P <0.05, P <0.01)., Conclusion: The positive reaction occurs most frequently in the Spleen Meridian, followed by the Liver Meridian, and least frequently in the Kidney Meridian. The acupoints with positive reaction are different between PD and SD, which suggests that the Spleen Meridian acupoints should be the main acupoints when treating the two kinds of dysmenorrhea, and acupoints should also be selected according to the meridian and acupoint examination results.

Objective: To observe the clinical effect of acupuncture by stages on secondary dysmenorrhea of adenomyosis through prospective case-series study., Methods: A total of 36 cases of adenomyosis patients with moderate-to-severe dysmenorrhea were treated with acupuncture by stages. The acupoints of Diji (SP 8), Sanyinjiao (SP 6), Ciliao (BL 32) and Shiqizhui (EX-B 8) were selected and acupuncture was given once a day during menstrual period; the acupoints of Guanyuan (CV 4), Zigong (EX-CA1), Sanyinjiao (SP 6) and Zusanli (ST 36) ect. were selected and acupuncture was given twice per week during non-menstrual period. All the treatment was given for three menstrual cycles. The visual analogue scale (VAS), Cox menstrual symptom scale (CMSS), Endometriosis Health Profile-5 (EHP-5) scores and the menstrual blood volume of pictorial blood loss assessment chart (PBAC) were observed before treatment and at the 1st, 2nd and 3rd menstrual cycle into treatment. Before treatment and at the 3rd menstrual cycle into treatment, the volume of uterus was measured by transvaginal ultrasound and the correlation among the quality of life, the severity of pain and symptoms was analyzed., Results: The VAS, CMSS and EHP-5 scores at the 1st, 2nd and 3rd menstrual cycle into treatment were lower than those before treatment ( P <0.01, P <0.05), and the PBAC scores were reduced but without statistical different ( P >0.05). Compared before treatment, at the 1st, 2nd and 3rd menstrual cycle into treatment, the PBAC scores were reduced in patients with PBAC>100 points ( P <0.01). Compared between 2nd and 1st menstrual cycle into treatment, between 3rd and 2nd menstrual cycle into treatment, the VAS, CMSS scores were all decreased ( P <0.01, P <0.05). There was a significant positive correlation between the severity score of CMSS and EHP-5 at the corresponding time points of the 1st, 2nd and 3rd menstrual cycle into treatment ( P <0.01)., Conclusion: The acupuncture by stages has significant analgesic effect in patients with secondary dysmenorrhea of adenomyosis, and has the advantages of relieving the menstruation-related symptoms, regulating menstrual blood volume and improving the quality of life.

To discuss the acupuncture and moxibustion thoughts of diagnosis and treatment for secondary dysmenorrhea of adenomyosis on the basis of disease location and pathogenesis. In clinic, we take the "principle, method, prescription, acupoint and technic" as the outline, paying attention to identify disease location and establishing the method of "promoting blood to remove stasis, regulating thoroughfare vessel and conception vessel" on the basis of the pathogenesis of "stasis obstructing uterus, disharmony of thoroughfare vessel and conception vessel". The prescription combines "dredging" with "conditioning", and the emphasis should be different in different periods. In menstrual period, we put emphasis on activating the circulation of qi and blood as well as clearing meridians to relieve pain and choose the acupoints on the spleen meridian of foot- taiyin and experimental points, such as Diji (SP 8), Sanyinjiao (SP 6), Ciliao (BL 32), Shiqizhui (EX-B 8). In the intermenstrual period, we regulate the qi and blood of thoroughfare vessel and conception vessel, and the function of viscera. The acupoints for the disease root are mainly at spleen meridian of foot- taiyin and conception vessel, such as Sanyinjiao (SP 6), Guanyuan (CV 4), Zigong (EX-CA 1), Zusanli (ST 36). And the reinforcing and reducing technic are applied accordingly.
