Objective To estimate the frequency of heart valvular involvement in Chinese patients with Takayasu arteritis (TAK) and its correlation with other clinical features. Methods Ninety-one patients with TAK were studied and their clinical manifestations, laboratory test, vascular images and echocardio - gra-phic findings were retrospectively reviewed. The data were compared between patients who had heart valvular involvement and those who had not. Mann-Whitney U-test or Student's t-test, Chi-squared test or Fisher's exact test were used for analysis. Results Aortic regurgitation and mitral regurgitation were both confirmed in 20 (22%) patients. Tricuspid regurgitation and pulmonary valve regurgitation were observed in 10 (11%) and 2 (2%) patients, respectively. Older age at onset, longer disease duration, hypertension and involvement of the ascending aorta were all significantly more frequent in TAK patients with aortic regurgitation (t=2.903, P<0.01; Z=-2.759, P<0.01; χ2=7.918, P<0.01; Z=-4.454, P<0.01) than those without. However, the constitutional symptoms and acute phase reactants [erythrocyte sedimentation rate (ESR) and C reactive protein (CRP)] were not statistically different between patients with and without valvular regurgitation (P>0.05). Aortic valvular pathology examination of the three TAK patients who had underwent aortic valve replacement showed no inflammatory cell infiltration. Conclusion This study has demonstrated that heart valve involvement is common in patients with TAK, mainly in the form of regurgitation, and which may be secondary to hypertension and other cardiovascular complications. We should pay more attention to the screening and treatment of heart valvular involvement in TAK patients.

This research was based on the theory and method of International Classification of Function, Disability and Health (ICF) and looked into the issues of physical function and disability. It tried to explore the purpose, knowledge structure and curriculum of special physical education that met the needs of social development and to restructure the curriculum and content of special physical education. Stu-dents of special physical education should not only master basic specialized knowledge, but also be able to practice theories, so as to better serve all kinds of children with special needs in training, assessment and intervention.

Objective: To prepare the pH dependent-microbially triggered colon targeted pellets of Rheum and optimize the preparation formulation of the targeted pellets. Methods: The pill-core was prepared by dropping preparation method, the pill-core fomulation was optimized by the orthogonal test, with drug loading, entrapment rate, and releasing rate as indexes. With release performance as index, the lagging cover weight increment was screened, the Rheum pellet that released at colon was obtained. Results: The 2% alginate-pectin solution, 0.7% chitosan solution, 1% CaCl2 solution, chitosan-CaCl2 solution with pH of 6.0, and the 4∶1 quantity of reagent (Rheum-accessory) were chosen as the top gallant fomulation to prepare the pill core, then enteric coating weight increased to 30% and the enteric coated-pellet was obtained. In gastric juice after 2 h and in small intestinal juice after 3 h, the coated pellet is cumulatively released to 2.01% and 8.72%, respectively, and released to 92.58% in the colon fluid after 4 h. Conclusion: The preparation fomulation of colon targeted pellet of Rheum is definited, and the colon targeted release is preliminary implemented.

Infected pancreatic necrosis (IPN) is a serious complication which may cause organ failure and death in patients with acute pancreatitis. Surgical debridement is an important therapeutic approach for IPN. With the development of evidence-based medicine, more and more high-level evidences emerge for surgical debridement of pancreatic necrosis tissue, and the traditional treatment strategy has also changed. In the era of minimally invasive surgery, whether 'delayed surgery' should still be executed and how to achieve 'delayed surgery' are the research hotspots in the treatment of IPN. Research evidences reveal that the 'step-up' strategy is not the best strategy for all IPN patients, and alternatives should be explored. In addition, the indications, advantages and disadvantages of open surgery, surgical minimally invasive surgery and endoscopic surgical debridement of pancreatic necrosis tissue have been widely discussed in recent years, and no consensus has yet been reached. At present, the personalized, multidisciplinary, and minimally invasive treatment of IPN is still the mainstream development direction. The authors investigate the timing and strategy of surgical treatment for IPN in order to provide theoretical basis for clinical practice.

Objective To evaluate the efficacy of internal fixation with or without fusion in the treatment of thoracolumbar burst fractures.Methods Clinical controlled trails related to the application of pedicle screw instrumentation with or without fusion for thoracolumbar fractures before March,2012were obtained by searching PubMed,Science Direct,Medline and CNKI.Quality evaluation was made on the included literature,from which data were extracted to integrate various rescarch results by using RevMan 5.1.The quantitative data were analyzed based on the effect scale of mean difference (MD) and bilateral 95％ confidence interval (CI).The numeration data were analyzed in the use of effect scale of odds ratio (OR) and bilateral 95％ CI.The merging of some data was manually completed.Results After retrieving,eight English and one Chinese papers of the clinical controlled trials,and two related Meta analysis were obtained.With exclusion of one repetitive research,eight papers were involved in the review.Meta analysis demonstrated that fusion and non-fusion fixation had no significant differences in aspects of correction of kyphotic angle,correction and correction loss of vertebral body height,neurological function improvement,complication rate,and length of hospital stay.While compared with the fusion fixation,non-fusion fixation showed a more serious correction loss of kyphotic angle,a fewer blood loss and a shorter operation time.Conclusions Non-fusion fixation shows the similar efficacy with fusion fixation in the treatment of some thoracolumbar burst fractures pertaining to releasing compression,restoring spinal stability and preventing complications,but it can also significantly decrease operation time and blood loss.Furthermore,non-fusion fixation may markedly improve patients' quality of life since it restores motion of the instrumented segment after removal of implant and decreases the risk of adjacent segmental degeneration.

Objective Investigations regarding the status of pediatric emergency and relevant facilities distribution in our province represent a crucial prerequisite for further setting up emergency network and improving our first aid capabilities.Methods We had conducted relevant surveys on the medical institutions within our province,including lever 2 and lever 3 hospitals as well as maternal and child care service centers.Results The feedback from 151 institutions indicated that they had 4485 pediatric beds and treated 5 308 severe patients in 2010.Among all,38 hospitals had ventilators for children and 4 hospitals could perform pediatric blood purification treatment.However,no one had mastered the children ECMO technique.Conclusion There is an inadequacy of some emergency equipments and the development in emergency and first aid is uneven.There is a strong request to launch and develop the blood purification and bronchfiberscope techniques,in combination with improvements in the first aid capabilities and emergency network.

Objective To investigate the role of self-made auxiliary device in pelvic tumor radiotherapy with phantom immobilization using Varian cone-beam CT (CBCT).Methods A total of 50 patients with pelvic tumor were enrolled and randomly divided into study group and control group according to the order of enrollment.The patients in the study group were immobilized with thermoplastic phantom and self-made auxiliary device,and those in the control group were immobilized with thermoplastic phantom.CBCT scan and online matching were regularly performed before radiotherapy to obtain the setup errors of the left-right (x),cranial-caudal (y),and anterior-posterior (z) directions.The independent-samples t-test was used for comparison between groups.Results The set-up errors in the x-,y-,and z-directions in the study group were 1.56± 1.00 mm,1.60± 1.29 mm,and 1.36± 1.00 mm,respectively,and those in the control group were 1.76±1.33 mm,2.76±1.69 mm,and 1.92±0.91 mm,respectively (P=0.551,0.009,and 0.043).Conclusions Self-made auxiliary device helps to eliminate the errors in the cranial-caudal direction and solve the problem of involuntary activities of the lower limbs.
