SUN Shu-chun,the chief researcher,is one of the famous expert of osteo-traumatology of TCM.He makes systematic sort and study on chirismus on basis of succeeding experience predecessors and his own years of clinic experience.He is good at treating cervical syndrome with TCM chirismus,especially combine it with drugs.In osteo-traumatology academic circles,he is called "the best doctor at home".Professor SUN advocates that the rule of applying various therapies according to different conditions,combination of rigid-flexible,light,skill,gentle,harmony should be obey when we use chirismus.His diagnostic and therapeutic methods and thoughts are original and ingenious.In this article,the author analyzes the academic experience of tendon trauma of professor SUN.

Objective To explore the effect of designing and applying project teaching scheme in higher vocational nursing clinical curriculum. Methods Sophomores of nursing major in grade 2009 and 2010 were selected as experiment subjects. Lecture-based traditional teaching method was applied in tradition group (121 students in grade 2009) while project teaching was applied in reorga-nization group (128 students in grade 2010). The teaching method was evaluated through thoretical exam, vocational skill test, professional quality test and questionnaine surrey. Data were input by us-ing SPSS17.00. T-test and Ranksum test were applied. Results Vocational skill test results of tra-dition group and reorganization group were (76.67 ±13.072) and (85.48 ±10.085) respectively;professional quality test results were (74.77±13.865) and (87.04±8.982), respectively. Differences in both groups had statistical significances (P<0.001). Evaluation on the teaching method was carried out in both groups through a questionnaire. (716/1408) of students in reorganization group thought that project teaching can improve 11 items including comprehensive quality. Except for the item of the-oretical knowledge comprehension, the rest 10 items of both groups had statistical significances (P<0.001). Conclusion Implementation of project teaching in nursing clinical curriculum helps to im-prove students' professional core competence.

Objective To screen for differential expression of genes in bone marrow mesenchymal stem ceils (MSCs) stimulated by electromagnetic fields (EMFs) and to study the mechanism of differentiation of the bone mar- row MSCs induced by EMFs.Methods Mouse bone marrow MSCs were isolated and cultured in vitro.The third- passage cells were stimulated by EMFs,then the total RNA was extracted,purified to cDNA and reversely transcribed to yield a cRNA probe.The cRNA probes from stimulated and control cells were labelled with Cy5 and Cy3,respec- tively.The two samples were hybridized with a mouse oligo microarray,and the hybridization signals were scanned. The reverse transcriptase polymerase chain reaction (RT-PCR) was used to identify the interesting genes:Duspl and Rabl.Results A total of 153 differentially expressed genes were found comparing the stimulated group and the control group.There were 74 up-regulated genes and 79 down-regulated genes in the stimulated group.Semi-quantita- tive RT-PCR confirmed that the Duspl and Rabl mRNA expression levels of the stimulated group were up-regulated. Conclusion The gene expression profiles of the bone marrow MSCs were altered after EMF exposure.The genes are involved in cell proliferation and differentiation,transcription control,metabolism and response to stress.These re- sults provide deeper insight into the mechanism of differentiation of the bone marrow MSCs.

Objective To observe the outcomes of intranasal endoscopic holmium laser-assisted dacryocystorhinostomy in the treatment of chronic dacryocystitis. Methods Forty-seven patients(47 eyes) with chronic dacryocystitis underwent intranasal endoscopic holmium laser-assisted dacryocystorhinostomy.The postoperative follow-up included lacrimal irrigation and intranasal endoscopic examination. Results The patients were followed up for 3 to 6 months.The cure rate was 87.2%,the improvement rate was 6.4%,and the total effective rate(cure rate+improvement rate) was 93.6%.Conclusion Intranasal endoscopic holmium laser-assisted dacryocystorhinostomy causes no scar in the face,less nasal tissue damage,shorter operation time and less hemorrhage,and does not affect the lacrimal irrigation system,which allows correction of intranasal causes of failure in traditional dacryocystorhinostomy.

Teachers are the most important resources of colleges and univesities. Setting up the teachers' competence model of medical colleges and universities is the basis of guaranting the quality of medical education, which accords with the need of the post training of teachers and can be the basis for teachers' competence assessment.

BACKGROUND:From the biological structure, the posterior cruciate ligament is surrounded by the synovial folds of posterior capsule, arising from the inner side of the medial femoral condyle to the posterior part of tibial intercondyloid spine. The main traditional treatment method for posterior cruciate ligament tibial avulsion fracture is open operation, but it is difficult in anatomic reduction, cannot ful y restore knee joint stability and has a great negative impact on the normal function of posterior cruciate ligament. OBJECTIVE:To investigate the effects of arthroscopic implant internal fixation in the treatment of tibial avulsion fracture of the posterior cruciate ligament. METHODS:120 patients with tibial avulsion fracture of the posterior cruciate ligament were randomly assigned into treatment group and control group, with 60 cases in each group. The control group was given the traditional open surgery, and the treatment group was given the arthroscopic surgery. After 3 months, International Knee Documentation Committee (IKDC) scores and Lysholm scores were detected in the two groups;the knee joint range of motion was determined before and 3 months after treatment. RESULTS AND CONCLUSION:Wounds were healed at stage I in al patients with no serious complications. There was no difference in the knee joint range of motion between the two groups before treatment, but the range of motion was increased significantly in both two groups at 3 months after treatment (P<0.05), meanwhile which was higher in the treatment group than the control group (P<0.05). At 3 months after treatment, the excel ent knee function rate was significantly higher in the treatment group (97%) than the control group (88%) according to the Lysholm scores;the IKDC scores were significantly higher in the treatment than the control group in terms of claudication, support, pain, swel ing, and squat (P<0.05). These results indicate that the arthroscopic implant fixation of tibial avulsion fracture of the posterior cruciate ligament has better short-term effects to promote recovery of knee joint function, but no serious complications.
