BACKGROUND: Fixation of bone fracture is one of the fundamental methods for bone fracture healing. The technique of AO has a lot of defects, such as negative effect induced by "stress dodging". Recently, the technique of CO is praised highly by national and international scholars. OBJECTIVE: To observe the influence of external fixation of small splint on healing of long bone fracture of rabbit, and compare to the internal fixation of steel plate.DESIGN: Randomized and controlled animal trial. SETTING: Research Institute of Orthopedics, Hubei College of Traditional Chinese Medicine.MATERIALS: The experiment was performed at the Laboratory of Orthopedics, Hubei College of Traditional Chinese Medicine from April 2006 to April 2007. Thirty rabbits were randomly divided into small splint fixation group and steel plate fixation group with 15 rabbits in each group. Small splint was self-made of fir-barks with good elasticity, and composed of exterior, interior, front and back splints. The upper part of the splint was wide and the lower part was narrow. We sting an eyelet in the small splint that is used in front and behind part. A hole was drilled in the front and back splints close to the tubercle of tibia. Steel plate was provided by Jiangsu Golden Deer Group (Type HA2.0). METHODS: The standard models of transverse fracture of 3 mm in the meta-infer 1/3 of left tibia were established. In small splint fixation group (SSF group), the fracture was fixed by plaster stone, and 5 days later, replaced by external fixation of small splint. The steel fixation group (SF group) was fixed by steel plate with 4 holes. Animals were executed 14, 24, and 34 days after surgery, respectively. The growth condition of bony callus in fracture sites was observed, and the histomorphology of bony callus and bone cell production during fracture healing was observed. MAIN OUTCOME MEASURES: Macroscopic observation of rabbit tibial bony callus, and histomorphology of bony callus and bone cell formation. RESULTS: In SSF group, the bony callus formed early, and there were plentiful and active osteoblast. Thirty-four days after surgery, bony union was observed in fracture sites. In SF group, there was little fibrous bony callus in the fracture ends 14 days after surgery, accompanied by granulation tissue. Twenty-four days after surgery, sparing cartilage synostosis was observed. On day 34 days, bony callus span the fracture ends, but fracture ends did not connect completely yet. Compared with the SF group, the quantity of bony callus and the speed of fracture healing were superior in SSF group. CONCLUSION: The external fixation of small splint can promote osteoblastic differentiation and proliferation, absorption of hematoma, calcification of the bony callus, and the growth and rebuilding of bone trabecula.

Objective To observe the clinical efficacy of triple needling at myofascial trigger points plus warm needling in treating periarthritis of shoulder. Method Eighty patients with periarthritis of shoulder were randomized into a treatment group of 44 cases and a control group of 40 cases. The treatment group was intervened by triple needling at myofascial trigger points plus warm needling, while the control group was by warm needling alone. The two groups were treated once a day, 10 times as a treatment course. The Pain Rating Index (PRI), Visual Analogue Scale (VAS), Present Pain Intensity (PPI), and motion of shoulder joint were observed before the treatment and after 2 treatment courses, and the clinical efficacies were compared between the two groups.Result In the treatment group, the PRI, VAS, and PPI scores respectively after 1 and 2 treatment courses were significantly different from those before the treatment (P<0.05,P<0.01). In the control group, the scores after 2 treatment courses were significantly different from those before the treatment (P<0.05). After 2 treatment courses, the scores in the treatment group were significantly different from those in the control group (P<0.01). In both groups, the motions of shoulder joint respectively after 1 and 2 treatment courses were significantly changed compared with those before the treatment (P<0.01). The motions of shoulder joint in the treatment group were significantly different from those in the control group respectively after 1 and 2 treatment courses (P<0.05,P<0.01). The recovery plus markedly-effective rate and total effective rate were respectively 70.5% and 95.5% in the treatment group, versus 52.5% and 90.0% in the control group, and the between-group differences were statistically significant (P<0.01,P<0.05).Conclusion Triple needling at myofascial trigger points plus warm needling is an effective approach in treating periarthritis of shoulder.

Objective To investigate the effect of applying web based problem-based learning in the teaching of bilingual curriculum.Methods 2009 grade nursing undergraduate bilingual class (n =57) was taken as control group and traditional teaching method was used.2010 grade nursing undergraduate bilingual class (n =60) was taken as experimental group and bilingual course of introduction to nursing was used to do web based (Blackboard platform) PBL teaching.Teaching process of the grouping-question posing-data gathering-discussion-mid-term feedback-presentation-summary and evaluation was implemented.Result comparison method,network based PBL learning evaluation sheet and content analysis were employed to complete teaching effect evaluation.Data were analyzed by t test and P < 0.05 signifies statistically significant differences.Results Test scores of experimental group were significantly higher than that in control group (P < 0.05).Mean scores of positive items in web based PBL teaching scale were ≥3.84.Electronic learning file content analysis showed that excellent rates of 7 indicators (student participation,thinking ability,inquiry,etc) were ≥66.7%.Conclusion Web based PBL teaching model is good for improving teaching effectiveness in the teaching of bilingual curriculum.
