[GAO Wei-bin's clinical experience of electric eye acupuncture and stagnant-moving needling for ophthalmopathy].

Professor GAO Wei-bin's clinical experience of electric eye acupuncture and stagnant-moving needling for ophthalmopathy was introduced. The indications of electric eye acupuncture and stagnant-moving needling include external ophtalmoplegia and visual impairment. Professor GAO has proposed new acupoints at the ocular muscles attachment of eyeball, and put forward five experience points: Shangming point, Neiming point, Xiaming point, Waiming point and Tijian point. The points are selected according to different pathological changes of ocular muscles. In the treatment of ophthalmopathy, the tendons and vessels are often regulated at the same time. Neiming point, Shangming point, Xiaming point and Qiuhou point are the main points, with Fengchi (GB 20) and Gongxue (Extra) as the matching points. In addition, attention is paid to the application of stagnant-moving needling and electroacupuncture (continuous dense wave, frequency of 50 Hz).

Acupuncture for gender differences and similarities in cerebral activity of health volunteers: A pilot fMRI study.

This study aimed to explore the feasible gender differences and similarities in cerebral activity response to the acupuncture at local acupoints around knee.Fifteen male and 15 female healthy adults were recruited and included in this study. Functional magnetic resonance imaging (fMRI) was applied to measure cerebral activity response to acupuncture at Liangqiu (ST34), Xuehai (SP-10), Neixiyan (EX-LE4), and Dubi (ST-35).Acupuncture activated the postcentral gyrus, precuneus, temporal, posterior lobe, and occipital lobe in both males and females. When compared with females, males showed brain activation in the right middle frontal gyrus, inferior frontal gyrus, right precuneus, right superior parietal lobule, left cerebellum anterior lobe; and brain deactivation in the right frontal. When compared with males, females were observed brain activation in the right frontal lobe, right parietal lobe, and right middle temporal gyrus; and brain deactivation in the left and right medial frontal gyrus.The results of this study demonstrated that the neural effects of local acupoints around knee might be different between male and female subjects. Further clinical trials should take this gender effect into account in their design of studies.

[Progress of Researches on Mechanisms of Acupuncture Therapy in Regulating Brain Plasticity].

Brain plasticity is referred to the ability of the brain to change in structure and functional activities from microscopic aspects (synapses) in individual neurons to larger-scale aspects such as cortical remapping, neuronal remodeling, etc. in response to injury. Acupuncture has a positive effect in the treatment of cerebral diseases, thus leading to an increasing research on its underlying mechanisms in regulating brain plasticity. The present paper reviewed recent development of studies on acupuncture treatment of Alzheimer's disease, vascular dementia, cerebral ischemia, bone cancer pain, autism, etc. from 1) regulating synaptic plasticity (up-regulating the proportion of hippocampal synapses, increasing synaptic curvature, post-synaptic density, and numerical density, areal density, and lowering synaptic cleft); 2) increasing hippocampal post-synaptic potential slop, peak and peak area of population spikes to evoke long-term potentiation (LTP) by regulating the expression of glutamate N-methyl-D-aspartate (NMDA) and alpha amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid (AMPA) receptors, and growth associated protein (GAP-43); 3) down-regulating the expression of glial fibrillary acidic protein (GFAP) to suppress the activity of astrocytes in the ischemic cerebral area and hippocampus in cerebral ischemia rats, and in the spinal cord dorsal horns of bone cancer rats, etc. and promoting vimentin and connexin 43 expression; and 4) promoting neuronal remodeling, and repair and regeneration of the injured nerve in the central nervous system via regulating neuron-glia network, expression of nerve growth factor, brain derived neurotrophic factor, etc. The future studies should pay more attention to 1) the contribution of acupuncture intervention to the correlation between the initiation of the endogenous protective effect and the brain plasticity during the onset of nerve injury and repair of the injured nerve, and 2) standarization of stimulating quantity, manipulation and duration of acupuncture treatment, as well as the relationship between the stimulating quantity and efficacy.
