OBJECTIVE To discuss the mechanical virtual reality when acupuncture on Jianliao (TE 14) so as to get perform perceptual knowledge of acupuncture for beginners through studying 3D reconstruction of surrounding tissues of this acupoint. METHODS Related tissues were segmented and reconstructed by establishing mathematics model based on the operational(More)
OBJECTIVE To investigate the intra-retinal expression of neuroglobin (Ngb) and death of retinal ganglion cells (RGCs) in acute retina ischemia rats. METHODS It was an experimental study. The acute retina ischemia model was established by specific hypothesised left retina artery of Sprague-Dawley rats. Forty rats were divided into four groups (0, 15, 30,(More)

OBJECTIVE To discuss the problem difficult to be presented for nerves and blood vessels in the 3D reconstruction of acupoints through studying 3D reconstruction of Jianliao (TE 14). METHODS Muscles and other tissues were segmented by applying cointeractive segmentation method based on chromatic characteristic space; the nerve and blood vessels can be(More)
Acupuncture manipulations on Fengchi (GB 20) of famous doctors were taken through force feedback device, then the data was input into a digitized virtual human. Virtual Fengchi (GB 20) acupuncture force feedback simulation system was built through the virtual reality technology to achieve one-to-one high simulative manipulation effect for acupuncture(More)
This paper discusses the application of virtual reality technology in the 3-D visible human body and acupuncture research. Based on the 3-D visible human fused with the localization information and hierarchy of acupoints, the paper analyzes the force against the needle and haptic rendering during the needle manipulation according to the physical properties(More)
OBJECTIVE To display the Lung Meridian of Hand-Taiyin at the body surface in a virtual human. METHODS After defining the acupoints as the control points, chose suitable function interpolation to compose skeleton curve, actualize surface rendering and to rebuild a tube-like meridian model. RESULTS The rebuilt tubular meridian model had a good visual(More)
OBJECTIVE To study the effect of protein Nogo-66 on the expression of CD11b and MHC-II in retinal microglia of chronic ocular hypertension SD rats and the effects of protein Nogo-66 on the immunogenicity of injured retinal tissues. METHODS It was a control experimental study. Chronic ocular hypertension rat model was established by laser photocoagulation(More)
OBJECTIVE To observe the anatomic structure of Huantiao (GB 30) visually, to imitate the inserting process of the needle to explore the safty of needle insertion and improve the therapeutic effect of acupuncture in clinic. METHODS Combined with anatomic structure of acupoint, muscles and other tissues related with Huantiao (GB 30) were interactively(More)
By comparing and analyzing the similarity among the international scalp acupuncture, JIAO's scalp acupuncture and ZHU's scalp acupuncture, it is believed that the international scalp acupuncture is a combination of traditional acupuncture and other scalp acupuncture on the basis of channel theory of TCM, and this combination is worthy of discussion. However(More)
