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.

RESULTS　The expression of GAP-43 and NF-L were increased by Nerve Regeneration Factor on DRG′s culture. CONCLUSION　This study indicated Nerve Regeneration Factor may up-regulate the gene expression associated nerve growth on cultured nervous cells.

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 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.

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.

AIM:To study the effect of integrin β1 on multidrug resistance in gastric cancer and its possible mechanisms .METHODS:The expression of integrin β1 at mRNA and protein levels in the SGC-7901 cells and SGC-7901/DDP cells was determined by qPCR and Western blot .The expression of integrin β1 in the SGC-7901/DDP cells was silenced by antisense oligodeoxynucleotide .The cell viability was detected by the CCK-8 assay, the cell apoptosis were ana-lyzed by flow cytometry, and the protein levels of integrin β1, Bcl-2/Bax, cleaved caspase-3/caspase-3, cytochrome C ( Cyt-C) and p-AKT/AKT were determined by Western blot .RESULTS:The expression of integrin β1 at both mRNA and protein levels was significantly upregulated in SGC-7901/DDP cells.The expression of integrin β1 was increased in SGC-7901 cells treated with chemotherapeutic agents such as cisplatin , paclitaxel and 5-fluorouracil .Knockdown of integrin β1 induced apoptosis of SGC-7901/DDP cells with an increased sensitivity to the chemotherapeutic agents .Meanwhile , knock-down of integrin β1 downregulated the protein levels of Bcl-2/Bax, p-AKTSer473 and p-AKTThr308 , while promoted the release of Cyt-C and upregulated the protein level of cleaved caspase-3.CONCLUSION:Knockdown of integrin β1 increases the sensitivity of SGC-7901/DDP cells to the chemotherapeutic agents , and promotes the cell apoptosis via mitochondrial apop-tosis pathway .The mechanism may be related to the attenuation of AKT pathway by inhibiting phosphorylations of AKT at Ser473 and Thr308.

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.

Objective To explore the job tasks and qualifications of midwives in China for the next five years.Methods Anonymous surveys were sent by email to 80 professionals to learn the job tasks and qualifications of midwives in China using the Delphi method.The recipients include senior midwives, nursing administrators and nursing educators,senior obstetricians and gynecology department chiefs,as well as health administrators.Results Learnt in the survey were the qualifications and job tasks of professional midwives in China for the next five years.The system concludes 77 job tasks of midwives, among which 31 items are supposed to be completed independently.Conclusion China should develop the midwife system as soon as possible,strengthen the midwife training and education,develop the midwife access system and the corresponding laws and regulations for midwives,standardize midwife management,clear the midwife qualifications and job tasks,formulate normative midwife promotion system,and realize the midwifery scientific management.
