RÉSUMÉ
BACKGROUND:The three-dimensional structure of acupoint anatomy was integrated into the teaching of acupuncture manipulation. Combined with the implementation and application of the acupuncture and moxibustion in digital virtual human, it can greatly improve the teaching effect and learning interest. OBJECTIVE:To investigate the acupuncture virtual human with integration of virtual reality force feedback technology and tissue deformation. METHODS:Using virtual reality technology, with computer as the core, we generated a specific range of virtual environment with realistic visual, auditory and tactile integration, col ected clinical expert acupuncture technique, matched the sensing equipment that can reflect the intensity, displacement and speed sensing of acupuncture. Based on image segmentation of virtual human, we constructed human tissue mechanics model, built virtual acupuncture-force-feedback system, and faithful y transmitted to the operator by a force feedback device. On one hand, based on VOXEL-MAN virtual human development platform, we finished the three-dimensional browser redevelopment of the science of acupuncture and moxibustion of Shu acupoint, which provided visual perception for people. On the other hand, based on modern biomechanics theory, we established models by graphics and image processing technology and force feedback technology. The stress process of the structure of each layer in the acupuncture point area was given to people in a sense of touch by the manner of virtual reality and force feedback. RESULTS AND CONCLUSION:With the man-machine interactive operation platform of virtual acupuncture force feedback system, operator could see the dynamic process of acupuncture needle into human body, and could feel the real counterforce in the control terminal of force feedback instrument. By operating acupuncture needle in virtual environment of force feedback instrument, acupuncture was performed in virtual human. The system meets the two requirements:the feedback changes produced by tissue interaction were similar to real acupuncture feedback force data measured by instrument. The acupuncture needle entered into different tissues, a sense of power changed significantly;there was progressive feeling with different layers, reaching a realistic experience. During the whole training, the image was smooth;virtual needle was responsive, which better meets the requirements of virtual reality.

BACKGROUND:The correct and effective acupuncture manipulation of famous doctors are used to generate the realistic visual, auditory and tactile integrated computer virtual environments for acupuncture simulation based on the various techniques with the core of computer, which can greatly enhance the realism of the operator, and reduce the clinical acupuncture accidents. OBJECTIVE:To establish the virtual Shenshu acupuncture force feedback simulation system. METHODS:Based on the force feedback device, the Shenyu manipulations from the famous acupuncturists were col ected and integrated into the digital virtual body. On the three-dimensional digital human body integrated with information of Shenshu, the interaction force of needle body and tissues during the acupuncture process was analyzed with the virtual reality technology according to physical characteristics of the tissues within Shenshu, in order to establish the mechanical model to simulate needle body force, and to transmit truly to the operator by the force feedback device. RESUTLS AND CONCLUSION:Shenshu virtual acupuncture force feedback simulation was preliminary established, and the sense of touch could be reproduced lively during mimic the acupuncture of Shenshu on the visualized virtual acupuncture human. Shenyu acupuncture force feedback researches have provided a preliminary exploration for virtual acupuncture that integrated with the information of visual, tactile and force feedback, and also provided a dynamic one-on-one simulation means for acupuncture teaching.

BACKGROUND:Based on the integration of virtual reality technology with acupoints, acupuncture can be expressed three-dimensional y. OBJECTIVE:To explore the structure of points through reconstructing digitalized three-dimensional visualization of Neiguan (PC6) structure based on VOXEL-MAN and Micro-XCT. METHODS:Muscles and other tissues adjacent with Neiguan (PC6) were segmented and merged based on the VOXEL-MAN system combined with the anatomical knowledge of acupoints;nerves and blood vessels were performed with three-dimensional reconstruction;the needle-inserting animation of Neiguan (PC6) was obtained by running script file. Three-dimensional visualization and virtual needle-inserting researches of Neiguan (PC6) were performed. Nature of the acupoints was detected by the Micro-XCT-200 machine additional y. RESULTS AND CONCLUSION:The visualization of the anatomical structure of local Neiguan (PC6) was completed, and the localization and expression of Neiguan (PC6) in the digitized virtual human were realized. The Neiguan (PC6) structure was researched with Micro-XCT-200, and showed there was no new tissue. Local three-dimensional reconstruction of the acupoint structure could help to display the anatomical structure of acupoints and simulate the acupuncture process. It could also help to observe the relationship between the needle body and the surrounding tissues during needle-inserting, which supplying a good basis not only for exploring the security of needle-inserting, but also for improving the clinical effect of acupuncture. The research on the structure of acupoint Neiguan (PC6) by Micro-XCT-200 provides further experimental evidence for the hypothesis of three-dimensional acupoint.
RÉSUMÉ
Objective:To explore the application of data mining in the literature study on acupuncture treatment Of headache,and to summarize the laws between TCM pattern identification of headache and acupoint selection,acupoint combination.Methods:In the study of the clinical literature about acupuncture treatment for headache,published domestically from 1950 to 2008,the number and frequency of the acupoints in the literature,and the selecting laws and frequency of the main acupoints in pattern identification,and the meridian-tropism relationship between the main acupoints and combined acupoints,and the distributing rules of commonly used acupoints on the body surface were investigated by frequency-analyzing method.Resuits:The main acupoints in acupuncture treatment of headache ale primarily the acupoints on the head and specific acupoints from yang meridians,with the acupoints combined in accordance with pattern identification by meridian theory for different paaerns.Conclusion:By analyzing the laws of acupoint selection in the acupuncture treatment of headache with data mining,its new laws can be obtained.

OBJECTIVE:To investigate the situation of adverse drug reactions(ADR) in our hospital.METHODS:In this retrospective study,a total of 270 ADR cases reported between 2005 and 2007 in our hospital were analyzed statistically in respect of the age and sex of patients,drug categories and clinical manifestations etc.RESULTS:Of the 270 ADR cases,patients aged ≤18 years or ≥50 years took the highest proportion(51.1% for the two age groups).The ADR were chiefly manifested as lesion of skin and its accessories,followed by the reaction of digestive system.90.74% of the ADR cases were induced by injections,and 191 cases(70.74%) were induced by antibiotics.CONCLUSION:ADR worth the highest alert in the clinic.
