This study observed the regional cerebral activation of the Waiguan (SJ 5) acupoint following true needling at the true Waiguan acupoint, sham needling at the true Waiguan acupoint and true needling at a sham point using fMRI. The fMRI results demonstrated that compared with sham needling, true needling at Waiguan activated the BA8 area and left cerebellum. Compared with needling at the sham point, needling at Waiguan activated the BA2 area, the left cerebellum and the right inferior semilunar lobule. Thus the activated brain areas caused by needling Waiguan may be the basis for treatment of certain diseases.展开更多

The authors put forward the hypothesis of the "acupoint-related brain". Single-photon emission computed tomography was used to explore the activation of brain regions following true needling in true acupoint Waiguan (SJ 5), sham needling in true acupoint Waiguan, true needling in a sham point, and sham needling in a sham point. The relative specificity of Waiguan in normal persons was analyzed by observing changes in regional cerebral blood flow. Compared with the sham needling in true acupoint group and sham needling in the sham point group, acupuncture at Waiguan can activate brain regions controlling movement. Compared with true needling in the sham point group, acupuncture at Waiguan can also activate brain regions controlling movement. The results suggest that the specificity of needling at an acupoint is related to certain activated cerebral functional regions, which are associated with the clinical application of the acupoint.展开更多

The present study examined Waiguan (SJ 5) as the acupoint of interest. We tested five conditions: a true needling at true acupoint group, a sham needling at true acupoint group, a true needling at sham acupoint group, a sham needling at sham acupoint group, and a healthy control group. We examined changes in glucose metabolism in different functional cortical regions to determine the specific brain activation elicited by acupuncture at Waiguan. The results revealed that true and sham acupuncture at the same acupoint activated different brain regions. In addition, applying acupuncture at a genuine acupoint and a neighboring sham acupoint activated different brain regions. These findings suggest that acupuncture at Waiguan causes activation in some brain regions.展开更多

Here, we investigated whether acupuncture at this acupoint in elderly patients with mild cognitive impairment can also activate neurons in these regions. Resting state and task-related functional magnetic resonance imaging showed that the pinprick senstation of acupuncture at the Taixi acupoint differed signiifcantly between elderly patients with mild cognitive impairment and healthy elderly controls. Results showed that 20 brain regions were activated in both groups of participants, including the bi-lateral anterior cingulate gyrus (Brodmann areas [BA] 32, 24), left medial frontal cortex (BA 9, 10, 11), left cuneus (BA 19), left middle frontal gyrus (BA 11), left lingual gyrus (BA 18), right medial frontal gyrus (BA 11), bilateral inferior frontal gyrus (BA 47), left superior frontal gyrus (BA11), right cuneus (BA 19, 18), right superior temporal gyrus (BA 38), left subcallosal gyrus (BA 47), bilateral precuneus (BA 19), right medial frontal gyrus (BA 10), right superior frontal (BA 11), left cingulate gyrus (BA 32), left precentral gyrus (BA 6), and right fusiform gyrus (BA 19). These results suggest that acupuncture at the Taixi acupoint in elderly patients with mild cogni-tive impairment can also activate some brain regions.展开更多

Methods: Duplicated MCAO model by Zea-longa's thread ligation was assessed by Zausinger's six-point method, and rats with 1-3 scores were chosen to be grouped. According to the randomized and controlled principle, rats were divided into 6 basic control groups (including normal group, sham group, model control group, model group without intervention, Nimodipine group, lateral-to-Renzhong group) and 6 acupuncture groups [including Neiguan (PC6) group, Weizhong (BL40) group, Chize (LU5) group, Sanyinjiao (SP6) group, Renzhong (DU6) group and non-acupoint group]; in each acupoint or non-acupoint 9 different parameter combinations were respectively set by orthogonal intersection method. There were in total 60 groups, and each group had 12 rats. The rats were treated by acupuncture with the lifting-thrusting manipulation every 12 h, in total 6 times. Indices of neurobehavioral scores, cerebral blood flow, infarction rate, microcirculation, and light microscope, etc. were measured. In order to comprehensively evaluate the acupuncture effect to research the specificity of acupoint, a cluster analysis was made with SPSS17.0 for the comprehensive effect scores of the samples computed according to the comprehensive evaluation models, and then sorting and classification were made for the comprehensive effect scores. Results: In the acupuncture groups every acupoint had different therapeutic effect due to different acupuncture parameter combinations; among the acupuncture groups the orders of curative effect were as followings: Neiguan group was of exceptional result, Weizhong group and Sanyinjiao group were of valid results in upper level, Chize group and Renzhong group were of valid results in lower level, and non-acupoint group was of invalid result; the therapeutic result of acupoint group was superior to non-acupoint group; and the curative effect of acupuncture group was also superior to basic control group. Conclusion: The acupoint has the specificity of acupuncture effect, and the acupoint specificity is relative.展开更多

Also it is the key factor for the efficacy of acupuncture treatment. Studies on acupoint specificity have aroused wide interest in scholars both at home and abroad. Some researchers abroad do not support acupoint specificity. Chinese scholars have, after years of research, preliminarily confirmed the existence of acupoint specificity. However, there is still no conclusive evidence to support acupoint specificity in terms of its specific physiological foundation, underlying mechanism and laws. This paper summarizes and analyzes basic and clinical researches on acupoint specificity in biological structure, physiology and acupoint effect, provides clues for further studies and develops the theoretical basis for acupont specificity.展开更多

However, these studies have no standard sham acupuncture control and many other factors can affect the clinical effect. These factors include needle retention time, treatment frequency, and the total number of treatments needed for satisfactory results, and all can change the clinical effect. The majority of existing acupuncture treatment studies do not consider these factors and lack standard dosage criteria. Therefore, it is still too early to conclude that sham acupuncture is as effective as traditional Chinese acupuncture. This article investigates the factors that influence the curative effect of acupuncture as to help set a standard for acupuncture studies in the future.展开更多

文摘Acupuncture point specificity is the theoretical basis for meridian and acupuncture theory. Also it is the key factor for the efficacy of acupuncture treatment. Studies on acupoint specificity have aroused wide interest in scholars both at home and abroad. Some researchers abroad do not support acupoint specificity. Chinese scholars have, after years of research, preliminarily confirmed the existence of acupoint specificity. However, there is still no conclusive evidence to support acupoint specificity in terms of its specific physiological foundation, underlying mechanism and laws. This paper summarizes and analyzes basic and clinical researches on acupoint specificity in biological structure, physiology and acupoint effect, provides clues for further studies and develops the theoretical basis for acupont specificity.

文摘Many clinical trials and experimental studies claim that sham acupuncture is as effective as traditional Chinese acupuncture. However, these studies have no standard sham acupuncture control and many other factors can affect the clinical effect. These factors include needle retention time, treatment frequency, and the total number of treatments needed for satisfactory results, and all can change the clinical effect. The majority of existing acupuncture treatment studies do not consider these factors and lack standard dosage criteria. Therefore, it is still too early to conclude that sham acupuncture is as effective as traditional Chinese acupuncture. This article investigates the factors that influence the curative effect of acupuncture as to help set a standard for acupuncture studies in the future.
