Effect of quantitative acupuncture manipulation on the skin temperature of acupoints / 中国针灸

<p><b>OBJECTIVE</b>To verify the effect of lifting-thrusting reinforcing manipulation at Hegu (LI 4) of the right side on skin temperature on the Large Intestine Meridian.</p><p><b>METHODS</b>Thirty healthy volunteers were needled at Hegu (LI 4) on the right side with lifting-thrusting reinforcing manipulation at the depth of 5 - 8 mm, 100 times/min in freqency for 1 min. With PowerLab 8/30 eight-channel high-speed recorders and specially equipped skin temperature detector, the temperatures of Shangyang (LI 1) on the bilateral side, Hegu (LI 4) and Kouheliao (LI 19) on the left side were tested at the time 30 min before the needling, 1 min during the needling and 30 min after the needling.</p><p><b>RESULTS</b>After the lifting-thrusting reinforcing manipulation on the right Hegu (LI 4), the average skin temperature (27.89 +/- 3.56) degrees C before the needling at the left Hegu (LI 4) was increased to (28.30 +/- 2.81) degrees C, the temperature of right Shangyang (LI 1) (24.57 +/- 4.29) degrees C was increased to (26.30 +/- 4.32) degrees C, left Shangyang (LI 1) (25.13 +/- 5.07) degrees C to (26.58 +/- 4.92) degrees C and left Kouheliao (LI 19) (32.11 +/- 1.68) degrees C to (32.25 +/- 2.15) degrees C, all of which were significantly improved to different degrees (P < 0.01, P < 0.05).</p><p><b>CONCLUSION</b>The lifting-thrusting reinforcing manipulation has an effect of increasing skin temperature of acupoints, and the temperature changes after needling are along meridians and have specificity of acupoins.</p>

Analysis on resistance testing and technological research of acupoints / 中国针灸

In order to summarize and analyze the progresses and problems of resistance testing and technology research on acupoints, investigate the related solutions, articles on resistance testing from 1990 to 2011 were collected, and advantages and shortcomings of different types of testing instruments were discussed in this article as well. Detection technology of acupoint impedance has under updating changes, which are often applied on locating acupoints and clinical diagnosis. The progresses of those technologies are mainly embodied in improvement of circuit model, which enable a longer testing duration, less media interference and so on. The previous studies often focus on resistance testing of the skin. Since dermal resistance does not equal to acupoint resistance, the designation of equivalent circuit does not embody the condition of cells, tissues and nerves at acupoints, and testing technology is often affected by factors such as polarization of electrodes, contact medium and anatomical characteristics of acupoints, the resistance of acupoints can not be taken as the effective framework of the diagnostic standard and judgement of therapeutic effect in clinic. Based on the key problems in resistance testing of acupoints, it is proposed by the article that the techniques and designation of circuit model should be reformed, and mathematical model should be established in the study to meet the requirement of the life system. Inductance of human body should be considered in resistance research of acupoints, and interference factors should be eliminate as far as possible in designation of equipments. Thus, the change law of acupoint resistance in the inner part of the body can be fully embodied by the designation of experiments.

Hard and soft tissue changes following the treatment of Class II division 1 malocclusion using twin-block appliance / 华西口腔医学杂志

<p><b>OBJECTIVE</b>To investigate the hard and soft tissue changes following the treatment of Class II division 1 malocclusion using Twin-block appliance.</p><p><b>METHODS</b>50 Class II division 1 malocclusion subjects whose handwrist radiographs were in FG-G stage were selected. One group (27 patients) was treated with Twin-block appliance, the other group (23 patients) was observed without treatment The acquired data of cephalometric of two groups were analyzed statistically with SPSS 11.0.</p><p><b>RESULTS</b>Soft tissue changes, Ls-E, Li-E, U1-Stms, Stms-Stmi, NsLs-FH, LsNsLi, LsNsPg', the angle of H decreased. Sn-Stms, Stmi-Me', Ns-Me', Sn-Me', NsLi-FH, NsPg'-FH, A'Ls-FH, B'Li-FH, LiB' Pg', CmSnLs, GSnPg', the angle of Z increased, there was statistically significant difference (P < 0.05). Hard tissue changes, SNB, L1-NB, IMPA increased, ANB, U1-SN, U1-NA, FMIA decreased, there was statistically significant difference (P < 0.05).</p><p><b>CONCLUSION</b>Sagittal relationship between upper- and lower-jaws is effectively improved after orthopedics with Twin-block appliance. Lower face height increases. Soft tissue profile tends to be straight-styled.</p>
