[Research on real-time data collection and demonstration system for acupuncture manipulation].

OBJECTIVE: To apply the real-time data collection and demonstration system for acupuncture manipulation to quantitative analysis of acupuncture manipulation for acupuncture teaching and research. METHODS: The real-time observation and analysis of parameter changes of acupuncture manipulation were implemented by this system. RESULTS: During the course of lifting and thrusting manipulation, the needle body moved in a uniform variable motion, and the action force was still kept while the arrival of Qi was achieved. During the course of twirling manipulation, the variations of twirling number and radian caused the changes of resistance moment, and this reaction was related to the body response. During the course of rotating and shaking manipulation, the radius for rotating and shaking was related to such factors as the force, the action point and the direction. CONCLUSION: The real-time data collection and demonstration system for acupuncture manipulation can provide a new experimental method for quantitative data analysis, standardized research and teaching demonstration of acupuncture.

[Electrical acupoint stimulation increases athletes' rapid strength].

OBJECTIVE: To search for a stimulation method for increasing athletes' performance. METHODS: One hundred and fifty athletes were randomly divided into a trial group and a control group, 75 athletes in each group. Acupoints were stimulated with audio frequency pulse modulated wave and multi-blind method were used to investigate effects of the electric stimulation of acupoints on 30-meter running, standing long jumping and Cybex isokinetic testing index. RESULTS: The acupoint electric stimulation method could significantly increase athlete's performance (P < 0.05), and the biomechanical indexes, maximal peak moment of force (P < 0.05), force moment accelerating energy (P < 0.05) and average power (P < 0.05). CONCLUSION: Electrical acupoint stimulation can enhance athlete's rapid strength.

[Effects of manual acupuncture and electroacupuncture on mitochondria of skeletal muscle cells in rats of acute swimming exercise].

OBJECTIVE: To observe effects of acupuncture and electroacupuncture on antioxidant enzyme and Ca2+(-) ATPase activities and Ca2+ content in mitochondria of skeletal muscle cells in rats of acute swimming exercise and explore the mechanism of acupuncture in increasing sport ability. METHODS: Forty male SD rats were randomly divided into 4 groups. The rats in the acupuncture group and the electroacupuncture group were treated respectively with acupuncture and electroacupuncture before acute swimming exercise. After the swimming exercise, the rats were killed and the skeletal muscle was taken, and then the indexes were determined. RESULTS: After acute swimming exercise, the GSH-Px and Ca(2+)-ATPase activities in the mitochondria of the skeletal muscle decreased significantly (P < 0.05) and Ca2+ content increased (P < 0.01) in the swimming group as compared with the control group; in the acupuncture group, SOD activity increased significantly (P < 0.05), GSH-Px and Ca(2+)-ATPase activities increased as compared with the swimming group (P < 0.05); Ca2+ contents in the swimming group and the electroacupuncture group significantly increased as compared with the control group (P < 0.01). CONCLUSION: Acupuncture can protect cells from injury of acute sports and maintain the functions of mitochondria so as to delay fatigue, prolong working time of muscles and prevent muscles from damage.

[Analgesic effects of electroacupuncture of different pulse waveforms in the rat of adjuvant arthritis].

OBJECTIVE: To explore the best pulse waveform of electroacupuncture for treatment of adjuvant arthritis (AA). METHODS: Forty Wistar rats were randomly divided into 5 groups. The electroacupuncture groups of AA were treated with different pulse waveforms of electroacupuncture, respectively. Pain threshold, swelling degrees of joint, and contents of 5-HT, beta-EP and LEK in local tissues of inflammation were observed. RESULTS: After the treatment, pain thresholds of the electroacupuncture groups with different pulse waveforms were higher than that of the model group (P < 0.05, P < 0.01); the local swelling degrees of inflammation in the electroacupuncture group were higher than that in the normal group (P < 0. 01), but was lower than that in the model group (P < 0.05, P < 0. 01); the contents of 5-HT in local tissues of inflammation in the electroacupuncture groups were lower than that in the model group (P < 0.05, P < 0.01); in comparison with the model group, the electroacupuncture of sound-electric wave increased the contents of beta-EP and LEK (P < 0.01, P < 0.05) and the electroacupuncture of intermittent wave increased the content of beta-EP in local tissues of inflammation (P < 0.05). CONCLUSION: Sound-electric wave is the best pulse waveform of electroacupuncture for treatment of adjuvant arthritis.
