| Objective:MRI of the hierarchy of portal points, acupuncture safety depth and angle of the system, measuring point on the Danshu and the key organization within the shortest distance, dangerous angle, outward and sides up30°,45°when the dangerous depth, determine the safety of acupuncture in depth, angle; of height, weight, BMI index and the relevance of needling depth. Acupuncture safe for clinical reference values, standard clinical practice of acupuncture.Method:According to body mass index (BMI) formula:BMI=weight/height 2 (Kg/m2) (17.8-22.9) criteria, select from the Heilongjiang University of Traditional Chinese Medicine called the study of 20 young volunteers (male 10,10 women), aged 22-30 years, mean 25.20±1.54 years. Subjects for each and every body measurements (height, weight, BMI index):According to The People's Republic of China national standard "acupoints name and location" (GB/T12346-2006) of the Meridian standard take on the Danshu of vitamin E with a fixed point surface marker. Application of superconducting magnet-based MRI GEsigna0.5T on points to level scan of the Danshu:the Danshu hole through both sides of the Danshu and the middle point of the level of the fault plane is axial (horizontal position) when the shortest distance to connect the section that is oblique sagittal section. T1 weighted images in the horizontal position, respectively, measured on oblique sagittal piercing dangerous depth, angle and diagonal stabbing dangerous skin surface was 30°, 45°diagonal stabbing dangerous when the depth to dangerous depth×75% for the Safety depth; dangerous angle-10°angle for safety. The results of statistical software with SPSS18.0 to show.Results:1. On the Danshu wall of the piercing point to the risk of pleural depth: (1)The depth is dangerous point men on the right 3.44±0.44cm, safe depth of 2.58±0.33cm, the depth of the left point risk 3.35±0.43cm, safe depth of 2.51±0.32cm; (2) Risk women the right point depth 2.98±0.30cm, safety depth 2.23±0.23cm, the depth of the left dangerous point2.89±0.29 cm, safety depth 2.17±0.22cm.2. On the Danshu of the acupuncture point perspective:(1) Men on the right acupuncture point out danger point is 28.72±5.68°, safety point of view is 18.72±5.68°, inward risk acupuncture point is74.26±2.29°, the security angle is 64.26±2.29°, the left points out Acupuncture is a dangerous point of 28.46±4.20°, safety point of view is 18.46±4.20°inward risk acupuncture point is 75.45±1.92°, safety point of view is65.45±1.92°; (2) Women the right acupuncture point out dangerous angle is25.38±3.80°, safety point of view is15.38±3.80°, inward risk acupuncture point is 75.42±1.51°, safety point of view is65.42±1.51°the left point out dangerous acupuncture point is27.70±3.42°, safety point of view is 17.70±3.42°, inward risk acupuncture point is 76.62±1.54°security angle is 66.62±1.54°3. On the Danshu of the acupuncture point to stab dangerous depth of internal tilt:(1) Man on the right risk acupuncture points in the depth 5.33±0.20cm, safety depth 4.00±0.15cm,dangerous men on the left needle points in the depth5.26±0.17cm, safe depth of 3.95±0.13cm; (2) Women in danger right acupuncture points in the depth of 5.23±0.11cm, safety depth 3.92±0.08cm, female on the left needle point in Barbed dangerous depth of 5.16±0.08cm, safety depth 3.87±0.06cm.4. On the Danshu and the next point out the depth of 30°diagonal stabbing:(1) Man on the right risk acupuncture points out the depth 3.50±0.70cm, safety depth 2.63±0.53cm,dangerous men on the left needle points out the depth3.56±0.75cm, safe depth of 2.78±0.57cm; (2) Women in danger right acupuncture points out the depth of 3.10±0.40cm, safety depth 2.33±0.30cm, female on the left needle point out Barbed dangerous depth of 3.28±0.59cm, safety depth 2.46±0.44cm.5. On the Danshu and the next point out the depth of 45°diagonal stabbing:(1) Man on the right risk acupuncture points out the depth 2.70±0.64cm, safety depth 2.03±0.50cm, dangerous men on the left needle points out the depth 2.69±0.61cm, safe depth of 2.02±0.46cm; (2) Women in danger right acupuncture points out the depth of 2.28±0.26cm, safety depth 1.71±0.20cm, female on the left needle point out Barbed dangerous depth of 2..37±0.36cm, safety depth1.78±0.27cm.6. Dangerous to male high index depth and correlation coefficient r= 0.359, p<0.2; women's risk of high index depth and correlation coefficient r =0.362, p<0.2; Dangerous to male weight index depth and correlation coefficient r=0.189, p<0..5; women's risk of weight index depth and correlation coefficient r=0.202, p<0.5; Dangerous to male BMI index depth and correlation coefficient r=-0.063,; women's risk of BMI index depth and correlation coefficient r=-0.046.Conclusion:1. Bilateral piont in danger of the Danshu hole depth, the male and female have obvious difference, tip the direction to consider when the acupuncture gender differences.2. Bilateral point in the hole to Danshu, inward dangerous risk view point there was no significant difference of men and women, suggesting the Danshu of the direction when acupuncture gender differences must not consider.3. Bilateral piont in inward hole on the dangerous depth inclined sting there was no significant difference of men and women, suggesting the depth of the direction when acupuncture need not consider sex differences.4. Bilateral piont in the hole to Danshu 30°,45, dangerous depth inclined thorn on when there was no significant difference of men and women, suggesting the Angle when need not consider acupuncture gender differences.5. The depth of the Danshu hole risk index was no significantly... |
