Core in jingjin diagnosis and treatment: yizhi weishu / 中国针灸

Jingjin (muscle region of meridian) is a distal diagnosis and treatment system of the sinew/fascia disorders on the base of the concept of jin in TCM. Jin should be a particular palpable structure rather than a single anatomic structure with a specific distributing course. Yizhi weishu refers to a idea running through the whole process of diagnosis and treatment of sinew/fascia disorders, in which, the results, obtained by the overall observation and palpation of patient's sinew/fascia structure, are taken as the criteria of treatment. Yitong weishu (taking the sites of sensitivity or tenderness as the points) verifies this idea in practice. Under the guidance of yizhi weishu, through identifying the primary from the secondary, and regulating yin and yang, the spasticity and flaccidity of sinews/fascia can be cured and the induced diseases treated. The diagnosis and treatment system of jingjin, based on yizhi weishu, develops the original jingjin theory with vague concept involved, formulates a systematic thinking of treatment for sinew/fascia disorders and provides a new approach to clinical treatment.

Effect of Shaolin internal qigong exercise on the surface electromyography signals of shoulder muscle groups in patients with capsulitis of the shoulder / 针灸推拿医学（英文版）

Objective: To unveil the efficacy of Shaolin internal qigong exercise in treating capsulitis of the shoulder (CS) and explore objective outcome measures by observing the changes in the surface electromyography (sEMG) signals of shoulder muscle groups after regular practice of Shaolin internal qigong exercise in CS patients. Methods: Sixty CS patients were randomized into two groups by the random number table method, with 30 cases in each group. Patients in the qigong group practiced Shaolin internal qigong exercise on a regular basis, while patients in the electroacupuncture (EA) group received EA treatment. Before and after treatment, the sEMG signals of six muscles, i.e. biceps brachii, triceps brachii, deltoid, pectoralis major, latissimus dorsi and trapezius muscles, of the affected side were recorded at 45° abduction of the shoulder, 60° forward flexion and 90° internal rotation with the elbow flexed during maximal isometric contraction, and the integrated electromyography (iEMG) of each muscle was calculated. Results: The total effective rate was 93.3％ in the qigong group, higher than 83.3％ in the EA group (P<0.05). Intra-group comparison showed that the iEMG of biceps brachii, triceps brachii, pectoralis major and deltoid muscles in the qigong group increased significantly after intervention at 45° abduction of the shoulder, 60° forward flexion and 90° internal rotation with the elbow flexed (all P<0.05), and the iEMG of trapezius and latissimus dorsi muscles decreased (both P<0.05); in the EA group, the iEMG of biceps brachii, pectoralis major and deltoid muscles increased significantly during contraction (all P<0.05), while the iEMG of triceps brachii, trapezius and latissimus dorsi muscles had no significant changes (all P>0.05). After intervention, there were significant differences in the iEMG of most of muscles between the two groups (all P<0.05), except for the iEMG of deltoid muscle at 45° of abduction of the shoulder joint during isometric contraction (P>0.05). Conclusion: Shaolin internal qigong exercise can effectively increase the motion intensity of the biceps brachii, triceps brachii, pectoralis major and deltoid muscles and reduce the compensation of the latissimus dorsi and trapezius muscles in CS patients; compared with EA, it produces a better result in improving the coordination and stability in shoulder joint movements.

Effect of acupuncture on oxidative stress and apoptosis-related proteins in obese mice induced by high-fat diet / 中国针灸

OBJECTIVE@#To explore the effect of acupuncture on oxidative stress and apoptosis-related proteins of liver in obese mice induced by high-fat diet.@*METHODS@#A total of 45 male C57BL/6 mice were randomized into a control group (10 mice) and a model established group (35 mice). Mice in the model established group were fed with high-fat diet for 16 weeks to establish the obesity model. After model established, 30 mice were randomized into a model group, a non-acupoint group and an acupoint group, 10 mice in each one. Acupuncture was applied at "Guanyuan" (CV 4), " Zusanli" (ST 36), "Yishu" (EX-B 3) in the acupoint group and the points of 0.5 cm and 1 cm to the base of tail in the non-acupoint group, 15 min each time, once a day for 8 weeks. Mice in the control group were fed with normal diet, while mice in the other 3 groups were fed with high-fat diet continuously for 8 weeks. The body weight was measured at 0, 4th, 8th, 12th, 16th, 20th, 24th week in each group respectively. After 24-week intervention, the weight of white adipose tissue of epididymis and perirenal and liver was measured; the levels of serum alanine transaminase(ALT) and glutamic oxaloacetic aminotransferase (AST) were detected by automatic biochemical analyzer; liver homogenate was used to detect the level of malondialdehyde (MDA) and the activity of superoxide dismutase (SOD); the liver morphology was observed by HE staining; the expression of apoptosis-related proteins Bax and Bcl-2 were detected by Western blot.@*RESULTS@#Compared with the control group, the body weight of mice in the model group, the acupoint group and the non-acupoint group was decreased on 16th week into experiment (before intervention, <0.05); compared with the model group and the non-acupoint group, the body weight of mice in the acupoint group were decreased after intervention (<0.05). Compared with the control group, the weight of white adipose tissue and liver, the levels of serum ALT and AST, the level of liver MDA, the expression of liver Bax were increased (<0.05); the activity of liver SOD and the expression of liver Bcl-2 were decreased in the model group after intervention (<0.05). Compared with the model group and the non-acupoint group, the weight of white adipose tissue and liver, the levels of serum ALT and AST, the level of liver MDA, the expression of liver Bax were decreased (<0.05); the activity of liver SOD and the expression of liver Bcl-2 were increased in the acupoint group after intervention (<0.05).@*CONCLUSION@#Acupuncture at "Guanyuan" (CV 4), "Zusanli" (ST 36) and "Yishu"(EX-B 3) can improve obesity and obesity related hepatic disorder by regulating oxidative stress and inhibiting apoptosis in liver.
