ABSTRACT
This paper reviewed the filiform needle insertionmethods in multi-edition of , explored its evolution and reasons, and analyzed its development trend. By referring multi-edition of and related literature regarding acupuncture manipulation published after 1940s, combined with acupuncture manipulation characteristics of modern and contemporary acupuncture masters, it was found that the definition of needle insertion methods needed to be improved after several changes. The classification of needle insertion methods was stable over development. The thrusting method of needle insertion was previously included, and then disappeared. The description of needle insertion methods was improving. These evolutions were mainly influenced by the academic and clinical background, the academic thought of writers and acupuncture masters, the internationalization and standardization of acupuncture and so on. The twist-inserting method and some other needle-inserting instrument meet the safe, sterile, painless and convenient development trend, which might be included in in the future.
ABSTRACT
Objective To compare the different effect of two gastric tube insertion methods in pa-dents undergoing computed tomographic virtual endoscopy. Methods 56 patients undergoing computed tomographic virtual endoscopy were randomly divided into group A and B according to gastric tube insertion methods, group A inserted gastric tube to descending duodenum by gastroscope, group B inserted by Jag precursor via nose. One- time success rate and the incidence rate of side effect were compared between the two groups. X2 test was adopted. Results One- time success rate of group A and B was 33.3%, 82.9% respectively, with obvious statistic difference. The incidence rate of side effect of group A was higher than that of group B. Conclusions Inserting gastric tube to descending duodenum by Jag precursor via nose is convenient, time- saving, causing less pain and resulting in higher success rate.
ABSTRACT
PURPOSE: To compare clinical and radiological results between standard insertion method and semiextended method which was designed to improve proximal fixation and alignment in proximal tibia fracture. MATERIALS AND METHODS: A retrospective review from May 2000 to February 2004, identified 24 extraarticular fractures in proximal tibia, initially treated with locked intramedullary nails at least 1 year follow up. There were 12 open injuries, 4 segmental, 3 butterfly fragments and 17 comminuted. Semiextended method was used in 10 fratures and standard insertion method which is cephalad to tibial tubercle in 14. Follow up clinical assessment consisted of review of associated injuries and complications and these two methods were compared by postoperative angulation and displacement in anteroposterior and lateral radiographs. Data were analysed by t-tests. RESULTS: In semiextended group, average angulation was 2.3 degrees in coronal and 2.8 degrees in sagittal plane and average displacement was 4.5 mm in coronal and 5.3 mm in sagittal. In ordinary group, average angulation was 5.1 degrees in coronal and 7.4 degrees in sagittal plane and average displacement was 6.1 mm in coronal and 5.3 mm in sagittal. In semiextended group, there were significant reduction in coronal angulation (p=0.006) and sagittal angulation (p=0.001), but there was no significant difference in coronal (p=0.344) and sagittal (p=0.99) displacement. Both groups showed anterior, valgus angulation and posterolateral displacement in most cases. There were 14 associated injuries and one patient developed nonunion and was treated by nail exchange with autogenous bone graft. CONCLUSION: Our retrospective analysis demonstrated that semiextended method is effective for reducing coronal and sagittal angulation, but is not helpful for reducing displacement in both planes.

Infection is one of the most serious complications of acupuncture. But no infection ever appears without contamination, so the best method for preventing infection is to avoid contamination.<BR>There are two causes of contamination by acupuncture, namely, unsatisfactory disinfection of skin and contaminated neeedles. The former involves incomplete skin cleaning and inadequate disinfection. The latter is caused by contact with unsanitary matter. Some factors which are usually considered insignificant, such as contamination by needle tube, finger push technique, needle insertion technique or contamination in the needle case, should be re-examined.<BR>The author never touches the part of the needle which can penetrate the skin. This simple measure can help to prevent contamination of needles and consequent infection.
ABSTRACT
Dr. Youn-Sic Chun and coworkers invented the new machine for getting information about the relative effectiveness of the orthodontic appliances and we named it Calorific machine. The author and colleagues used this machine to compare with tooth moving mechanism by 3 types of the insertion method of precision-TPA for derotating the posterior teeth. We measured the distance of tooth movement and found out the rotational center on the occlusal X-ray film and the tooth movement on the occlusogram and then processed paired t-test by SAS program. The results were as follow : 1. In the intermolar width, the mesial insertion method showed the loss of distance, and the other methods(-distal insertion method, mesial expansion method-) showed the increase of distance. 2. In the arch length, the distal insertion method was exhibited as most recommandable way for increasing the arch length. 3. The rotation center of the mesial insertion method for derotating the molar, was located between mesial pit and central pit of the lower 2nd molar. and, in the distal insertion method, it was located between distal pit and distolingual cusp, and in the mesial expansion method was located at distal pit.

The authors' developed a new methods of preparing and inserting intradermal needles for small experimental animals.<br>To create the new type of needle, the tip of a filiform needle (0.14mm in diameter) was pinched into a wavy shape using mosquito forceps. A length of about 1.5mm of this wavy section was then cut off and used as an intradermal needle.<br>Designated areas of the mice were depilated, and the acupoints marked. For insertion, an injection needle (27 gauge) was used to penetrate directly beneath the marked point, starting from slightly above the marking. The wavy needle was then inserted into the tip of the injection needle and a filiform needle (0.18mm in diameter; adjusted length) used to push the wavy needle out, thereby inserting it into the intended point.<br>Using this method, insertion of the needles was easily carried out, and they stayed in places. This method therefore seems to be highly applicable for the insertion of intradermal needles in experimental animals.
