Methods: A total of 6 dysmenorrhea volunteer patients were subjected into this study. On the first positron emission tomography (PET) scan examination, they were assigned to pseudo-acupuncture group by using the acupuncture needle just to prick the skin of Sanyinjiao (SP 6); while on the second PET scans, they were assigned to acupuncture group by inserting the needle into the same acupoint. 18F fluorodeoxyglucose ( 18F-FDG) PET of the whole brain was performed during pseudo-acupuncture and real acupuncture of Sanyinjiao (SP 6). The acquired PET data were analyzed by using statistical parametric mapping (SPM) software to determine changes of glucose metabolism in different cerebral regions. The patient’s pain intensity was rated by using 0-10 numerical pain intensity scale. Results: After pseudo-acupuncture stimulation of Sanyinjiao (SP 6), no significant changes were found in the pain intensity (P>0.05), while after real-acupuncture stimulation, the pain intensity declined significantly (P<0.01). Following acupuncture of the right Sanyinjiao (SP 6), multiple cerebral regions involving pain were activated (increase of glucose metabolism), including ipsilateral lenticular nucleus (globus pallidus, putamen), ipsilateral cerebellum and insular lobe, bilateral dorsal thalamus, ipsilateral paracentral lobule, bilateral amygdaloid bodies, contralateral substantia nigra of the midbrain, bilateral second somatosensory (SⅡ) areas, ispsilateral hippocampal gyrus, frontal part of the ipsilateral cingulated gyrus, and bilateral mammary bodies of the hypothalamus. In addition, fewer regions of the cerebral cortex responded with decrease of the glucose metabolism after real acupuncture.展开更多

The primary outcome was average menstrual pain(VAS-P). Secondary outcomes included the pulsatility index(PI), resistance index(RI), and systolic-diastolic peaks ratio(S/D) in uterine arteries as measured using color Doppler ultrasonography;anxiety as assessed using the Hamilton Anxiety Rating Scale(HAMA), blood pressure(BP),and heart rate(HR).Results: Forty-eight patients completed the study. The TN group exhibited a significant reduction in VAS-P scores(-5.71 mm, 95% confidence interval(CI): -8.78, -2.63, P =.001), RI values(-0.05, 95% CI:-0.09, -0.01, P=.015), and HAMA values(-2.50, 95% CI: -4.78, -0.22, P=.032) when compared with the PN group. No significant differences in PI, S/D, BP, or HR values were observed between the two groups(P >.05).Conclusion: TN at SP 6 was superior to PN in alleviating menstrual pain and anxiety in patients with PD.This analgesic effect of TN may be due to its better ability to improve uterine arterial blood flow via decreases in RI values.展开更多
