Altered Impedance of Ear Acupuncture Point MT2 in Breast Cancer Patients: A Preliminary Observation

Skin impedance at acupuncture points (APs) has been used as a diagnostic aid for more than 50 years. In this study, we have a diagnostic tool (JXT-2008) to measure the skin impedance of ear APs of 30 breast cancer patients and the corresponding skin impedance of ear APs of 30 healthy humans, and then we compared these changes in ear AP impedance in breast cancer patients and healthy individuals.

Motion video-based quantitative analysis of the ‘lifting-thrusting’ method: a comparison between teachers and students of acupuncture

Objective To compare objective measures of needle manipulation between students and teachers of acupuncture using motion video analysis technology, to help support instructional acupuncture education. Methods A total of 30 teachers and 60 students participated in this study. Acupuncture needles were inserted at LI11 and motion videos were recorded for three subtypes of ‘lifting-thrusting’ manipulation: (1) ‘mild reinforcing-attenuating’; (2) ‘reinforcing’; and (3) ‘attenuating’. The videos were analysed using Simi Motion 3D software to acquire the movement parameters of four trace marks: ‘thumb tip’; ‘forefinger tip’; ‘forefinger middle joint’; and ‘forefinger base joint’. Differences between the two groups were compared using t-tests, X2 tests and/or rank-sum tests. Results Changes in the near-end interphalangeal joint were positively associated with a range of movement along the X axis. Motion parameters for the thumb tip, the proximal interphalangeal (PIP) joint of the forefinger and the X axis shaft swing near the end of the forefinger in the teacher group were higher than those in the student group. The teacher group featured smaller trough dispersion and smaller crest dispersion during ‘reinforcing’ and ‘attenuating’ manipulations, respectively. Conclusions The ‘lifting-thrusting’ manipulation could be simplified as a fixed-axis rotation using metacarpophalangeal joints in the thumb and forefinger as the shaft centre. Teachers opened at a larger angular variation for the PIP during the lifting and thrusting processes with better spatial control. Temporal control was similar between groups and therefore appears easier to grasp. Repetitive training might be helpful for improving athletic and spatial stability during needle manipulation.

Peculiar Phenomena During Resistance Detection of Acupoints

Studying on resistance specificity of human acupoints is one of the major subjects in the research on acupoint specificity. Even since a long time ago, many methods have been put forward in the detection of acupoint resistance specificity. From the vertical lengthways of the acupoint structure, the methods and means are put forward to detect the acupoint resistance in a series of studies. In the studies, some peculiar phenomena are found out in the detection of the acupoint resistance, and some phenomena are interrelated with the volume conductor characteristics of the human body, and some phenomena might be interrelated with the detecting methods and means. By the summary and analysis of those peculiar phenomena, references are offered to the relevant researchers engaged in the detection of the acupoint resistance.

Development on single acupoint Electro-Acupuncture and its significancy Δ

Basing on analyzing property of the traditional Electro-Acupuncture (EA) and the exiting problem in clinical and experience, and the characteristic of traditional acupuncture therapeutics, we bring forward the conception of “single acupoint Electro- Acupuncture”(SAEA) and “Single-Acupoint Electro- Acupuncture therapeutics”(SAEAT), design the draft of single acupoint Electro-Acupuncture and work out its therapeutics, emphasize the significancy to set up the new electro-acupuncture therapeutics-SAEAT which embodies the traditional acupuncture feature (single acupoint stimulus).

Effects of Acupuncture On Mitochondria of Muscle Cell In Rats of Acute Swimming Exercise

Objective To research on the effects of acupuncture and electroacupuncture on antioxidant enzymes activity, Ca2+ content and Ca2+-ATPase regulation in rat muscle mitochondria after acute swimming exercise. Method Forty male SD rats were divided randomly to 4 groups. The rats in the acupuncture group and electroacupuncture group were respectively treated by the two different methods of acupuncture and electroacupuncture before acute swimming exercise. After the swimming exercise, the rats were executed and the needed materials were taken. Then the relational indexes were determined. Result After acute swimming exercise, the values of GSH-Px activity and Ca2+-ATPase in rat muscle mitochondria in the swimming groups decreased obviously than those in the control group (P<0.05), and the values of Ca2+ content increased obviously (P<0.01). In acupuncture group, SOD activity increased obviously (P<0.05). Compared with swimming team, GSH-Px activity and Ca2+-ATPase in acupuncture group increased obviously(P<0.05). Ca2+ content in swimming group and electroacupuncture group obviously increased than that in control group (P<0.01). Conclusions Acupuncture can protect cells to avoid the acute sports injury, maintain the functions of mitochondria so as to postpone fatigue, extend muscle working time and prevent muscle injury.
