METHODS: Patients with primary dysmenorrhea were enrolled and randomly assigned to a treatment or control group. Subjects' symptoms were differentiated into variousTraditional Chinese Medicine(TCM) syndromes and treated for 10 sessions with puncturing acupuncture or self-pressing right-hand Hegu(LI 4), adding other acupoints based on syndrome. Laser speckle was used to compare the change in the vasomotor amplitude and perfusion of the capillaries in Hegu(LI 4) before and during the treatment. Each subject was required to finish the period pain symptoms observation form, verbal rating scales, numerical rating scale, pain rating index, face rating scale, Zung self-rating depression scale, Zung self-rating anxiety scale, and numerical rating scale before and after treatments. RESULTS: After 10 sessions, the symptom scores, pain index(PI), and visual analog scale(VAS) decreased significantly in treatment group. The volume of blood flow in Hegu(LI 4) declined slightly. No significant evidence supported that needling caused capillary contraction, but the capillary vasomotor amplitude at Hegu(LI 4) increased remarkably. CONCLUSION: Acupuncture can increase the capillary blood flow, thus promoting the flow of Qi and blood in terms of TCM theory, which facilitates pain relief.展开更多

Methods: Twenty healthy subjects, 18 females and 2 males, aged averagely 36 years, were enrolled in this experiment. The traditional box-moxibustion and electrothermal Bian-stone moxibustion were respectively given on the hypogastrium around Guanyuan (CV 4), and the changes of local capillary blood perfusion in the body surface were investigated with Laser Doppler Perfusion Imaging (LDPI). Results:The traditional box-moxibustion was superior to the electrothermal Bian-stone moxibustion in the transient increasing effect in whole body and the long-term increasing effect in the local area of moxibustion on capillary blood perfusion; but for both methods, the increasing effect on the capillary blood perfusion in the local area of moxibustion was same. Conclusion: Electrothermal Bian-stone moxibustion can not completely take the place of the traditional box-moxibustion; but for some disorders with local pain, they possibly have the same effects.展开更多
