L'exposé comporte deux aspects distincts et reliés: le premier présente les structures énergétiques générales qui président à la nutrition et à la stimulation du bassin et des membres inférieurs, dominées par le yangming, l'énergie de l'Estomac et le méridien curieux chong mo. Le second explore la conscience spatiale du sujet en position débout et orienté dans l'espace tel que le suggère le Suwen 6 dans son évocation d'un axe fondateur guangming-taichong [37VB-3F] et les six niveaux énergétiques. Un parallèle est développé avec les études neurophysiologiques sur la Kinesthèse, touchant à la fois les rapports entre proprioceptivité, équilibration et conscience spatiale, visuelle, ainsi que les problèmes spécifiques posés dans l'évolution par la bipédie.

Guangming (GB37) gained its name before the writing of Huang di Ming Tang Jing (The Yellow Emperor's Mingtang Classic), the earliest work of the art of acupuncture point. However, in acupuncture and moxibustion works before the Song Dynasty, this acupoint was not used to treat eye diseases. In Dou Hanqing's Zhen jiu biao you fu (Song to Elucidate Mysteries in Acupuncture Moxibustion), Guangming was used to treat oculopathy as an alias of Cuanzhu (BL2). Influenced by this, the alias “Guangming” was mistaken as Guangming (GB37) of the Gallbladder Meridian in the Bian que shen ying zhen jiu yu long jing (Bian Que Acupuncture and Moxibustion Jade Dragon Classic) of the Yuan Dynasty, and the symptom of eye itch was added to the indications of Guangming (GB37). This was wrongly informed in the later acupuncture and moxibustion works, and the modern scholars also accepted it and confirmed its effect by the clinical and experimental research.
Changes in electroencephalogram (EEG) signals under repetitive magnetic stimulation at the acupoint of Guangming (GB37) were analyzed using nonlinear dynamics complexity. C0 complexity is a statistical indicators which can quantify time dynamics of EEG signals. The study compared the C0 complexity under magnetic stimulation at GB37 with those at a mock point, as well as the C0 complexity under visual stimulation before and after magnetic stimulation at GB37. The results showed that the C0 complexity values of EEG signals in the electrode F3,Cz,C4 and P3 were different depending on whether magnetic stimulation was at the GB37 or a mock point (P <; 0.05),and the C0 complexity of magnetic stimulation on GB37 was generally higher than that on mock point. Moreover, EEG signals from visual stimulation before magnetic stimulation at GB37 were significantly different from those after magnetic stimulation at GB37 in two electrodes which were C4 and P3(P <; 0.05). The conclusion of the study is that magnetic stimulation at GB37 has a significant impact on EEG signals. First, EEG complexity during magnetic stimulation at GB37 was significantly higher than that at the mock point in frontal area, central area and parietal area (electrodes F3, Cz, C4 and P3). Second, EEG signals in central area and parietal area (electrodes C4 and P3) resulting from visual stimulation differed depending on whether magnetic stimulation at GB37 was given. The study has important significance for the application of magnetic stimulation on acupoints.
Objective To observe the clinical efficacy of acupuncture at Guangming(GB37) and Diwuhui(GB42) in treating dry eye due to different syndromes. Method Thirty-nine dry eye patients(78 eyes) conforming to syndrome of up-flaming liver fire or liver-kidney yin deficiency were randomized into a distant group and a periocular group, to receive acupuncture at distant acupoints [Guangming(GB37) and Diwuhui(GB42)] and periocular acupoints [Cuanzhu(BL2), Tongziliao(GB1), and Taiyang(EX-HN5)], respectively. Result In the distant group, the total effective rate was 60.0% after 2-week acupuncture and 75.0% after 4-week acupuncture; in the periocular group, the total effective rate was 53.6% after 2-week acupuncture and 65.8% after 4-week acupuncture. There were no significant differences between the two groups(P>0.05). The tear production and tear film break-up time(BUT) were significantly improved in both groups after the intervention(P<0.05). The inter-group difference in the improvement of up-flaming liver fire syndrome score was statistically insignificant(P>0.05), while the inter-group difference in the improvement of liver-kidney yin deficiency syndrome score was statistically significant(P<0.05). Conclusion Acupuncture at Guangming and Diwuhui can boost the improvement of dry eye symptoms and tear production, and prolong BUT; dry eye due to up-flaming liver fire achieved a satisfactory therapeutic efficacy in both groups, while liver-kidney yin deficiency type responded better to acupuncture at distant acupoints.
OBJECTIVE: To preliminarily explore the electrophysiological mechanism of acupuncture on plasticity variability of visual cortex. METHODS: Fifty 14-day-old Wistar rats were randomly divided into a blank group, a model group, an early-stage acupuncture group, a middle-stage acupuncture group and a late-stage acupuncture group, 10 rats in each one. Except the blank group, the rats in the remaining groups were treated with eyelid suture to establish the model of monocular deprivation amblyopia. After model establishment, the rats in the blank group and model group were grasped without any intervention everyday. The rats in the acupuncture groups were treated with acupuncture at bilateral “Jingming” (BL 1), “Cuanzhu” (BL 2), “Fengchi” (GB 20) and “Guangming” (GB 37) on the 3rd, 12th and 21st days into model establishment. The needles were retained for 10 min, once a day for totally 9 days. After treatment, the M-NEMEA technology was applied to measure the discharge amplitude and power spectral density of visual cortex area 17 neuron of each group. RESULTS: Compared with the blank group, the number of discharged neuron of visual cortex area 17 was reduced, and the amplitude was significantly reduced in the model group (both P<0.05). Compared with the model group, the numbers of discharged neuron were increased, and the amplitudes were significantly increased in the early-stage acupuncture group and middle-stage acupuncture group (all P<0.05). The neuron discharge amplitude in the early-stage acupuncture group was higher than those in the middle-stage acupuncture group and late-stage acupuncture group (both P<0.05); the neuron discharge amplitude in the middle-stage acupuncture group was higher than that in the late-stage acupuncture group (P<0.05). In the 120-second time domain of acquisition, the distribution of power spectral density in the blank group was mainly between -105 dB and -100 dB; compared with the blank group, the power spectral density in the model group was increased and distributed between -132 dB and -124 dB; compared with the model group, the power spectral densities in the acupuncture groups was reduced and distributed between -115 dB and -110 dB in the early-stage acupuncture group, -120 dB and -115 dB in the middle-stage acupuncture group and -129 dB and -122 dB in the late-stage acupuncture group. CONCLUSIONS: There are abnormal changes of spatiotemporal pattern in visual cortex area 17 of monocular deprivation rats, but acupuncture can regulate abnormal spatiotemporal pattern of neuron. Therefore, there is developmental plasticity of visual cortex neuron in the sensitive period, and early treatment is key to superior efficacy.
OBJECTIVE: To manifest the specificity of acupoints objectively through observing the relationship of both Guangming (GB 37) and Hegu (LI 4) with the some areas of face.METHODS: The patients with peripheral facial paralysis were divided into the Guangming (GB 37) group and Hegu (LI 4) group, and punctured respectively. Before and after treatment, the distribution and change of facial temperatures were measured with infrared thermography and the data on each area was comparatively analyzed.RESULTS: After punctured at Guangming(GB 37), the temperature went up in the areas around the eyes of both health and affected sides, especially on the affected side, which was significantly different from the other facial areas (all P<0.05). After punctured at Hegu (IA 4), the temperature obviously went up in the area around the mouth, which was significantly different from other areas of face, such as the areas of Yintag and health eye. The temperature in the area around the affected eye was significantly higher than that of the area around the health eye.CONCLUSION: There is some close coordination between Guangming (GB 37) and eye area, as well as between Hegu (LI 4) and mouth area, suggesting the specificity of acupoints.
PURPOSE: To investigate whether electroacupuncture can prevent selenite-induced cataract in an experimental model. METHODS: Fifty Wistar rat pups were randomized into 5 groups of 10 animals: Group 1 (control), no procedure was performed; Group 2 (selenite), sodium selenite (30 micromoles/kg body weight) was injected subcutaneously between postpartum days 10 to 12; Group 3 (anesthesia) received the same dose of selenite and underwent ether inhalation anesthesia during 10 minutes daily for one week; Group 4 (electroacupuncture) underwent the same procedure of Group 3, but also receiving electroacupuncture (2 Hz, 50 mA) applied to the Neiguan (PC6) and Guangming (GB37) acupoints during the anesthesia period; and Group 5 (Sham) underwent the same procedures of Group 4, but needles were applied to non-acupoints. The development of cataract was assessed one week later, and its density was graded by slit lamp biomicroscopy. RESULTS: All control rats' lenses (Group 1) were clear. Groups 2, 3 and 5 rats developed more severe cataract or complete opacification. In Group 4 (electroacupuncture), 45% of eyes did not develop cataract while thirty per cent developed less severe cataract than Groups 2, 3 and 5. The between-group difference was statistically significant (p<0.001). Lens opacification grade in Groups 1 and 4 was lower than in the Groups 2, 3 and 5 (p<0.001). CONCLUSION: Electroacupuncture effectively decreased selenite-induced cataract formation rate in pup rats when needles were applied at specific acupoints.
