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 investigate the effects of azithromycin on hyperoxia induced lung injury in neonatal rats.Methods Ninety 2-day-old neonatal rats were randomly divided into 3 groups (30 cases in each group):air control group,hyperoxia model group,azithromycin treated group.The rats in air control group were exposed to indoor air,and the rats in hyperoxia model group and azithromycin group were exposed to 900 mL?L-1 O2 for 14 days.From 2-days-after birth,rats in treated group received intraperitoneal injection of azithromycin (200 mg?kg-1)per day,rats in air control group and hyperoxia model group received intraperitoneal injection of normal saline.Ten rats in each group were executed and their lung tissues were taken out and were observed under a optical microscope on the 3rd,7th,14th days from the start.The expression of interferon gamma(IFN-?),connective tissue growth factor(CTGF) and matrix metalloproteinase-9 (MMP-9) in the lung tissues were detected by immunohistochemistry.Results There was no expression of IFN-? positive cells in air control group,but the expressional intensity level was gradually enhanced as the time of inhaling hyperoxia prolonged in hyperoxia model group,it reached the peak on the 7th day,and then obviously declined on the 14th day,but still higher than that of air control group.The expressional intensity level of IFN-? in azithromycin treated group was lower than that of hyperoxia model group in each time segment,there were significant differences among them(Pa

Objective To discuss the management, complication and effectiveness of establishing a prolonged hemodialysis access with a long-term venous indwelling catheter. Methods During the penod of July 2007-February 2009, a total of 64 long-term venous indwelling catheters for hemodialysis were placed in 62 patients with terminal chronic renal insufficiency. Results Of the total 64 catheter-placements, 62 were pereformed under DSA guidance and 2 at bed-side. Because of blocked flow, adjustment of the catheter was carried out in 4 cases, replacement of catheter in 2 cases and thrombolytic therapy in one case. In 62 patients, the arterial flow rate after the procedure reached to 230-300ml/min. In 57 cases the indwelling catheter remained in working condition so far. Five cases died within 6 months. Conclusion For establishing a prolonged hemodialysis access. The placement of a long-term venous indwelling catheter is feasible. The main complication is the blocked flow. Which is mainly related to the disposition of the catheter itself or its tip. The right intemal jugular vein is the indwelling site of choice, the tip of double-lumen catheter should be within the superior vein cava. With the help of DSA guidance, the procedure can be performed accurately, safely and easily.

OBJECTIVETo investigate the clinical characteristics of children with Castleman's disease and to improve doctors' awareness of this disease.

METHODSClinical characteristics of 5 cases with Castleman's disease were observed and analyzed and relevant reports in literature were reviewed.

RESULTS(1) All the five patients' histories were long, and the first symptoms of them were painless lymphnode enlargement, and all of them were at school age; 3 patients' abdominal lymphnodes were enlarged, mediastinum lymphnodes enlarged in 3 cases, cervical lymphnodes were involved in 3 cases; (2) The clinical subtypes: the disease in 3 cases was localized Castleman's disease (LCD), all of their pathological subtype was hyaline vascular variant (HV). The rest of them were multicentric Castleman's disease (MCD), whose pathology was plasma cell variant (PC), and both of them had a febrile symptoms; (3) The white blood cells, C-reactive protein and ferritin levels were all elevated to different extents. Four of them had viral infections, and their cellular immune function was abnormal; (4) The LCD patients' prognosis was good after the complete resection. There is no standard therapy for MCD, the available therapies include antiviral, immune modulatory regimens, CD20 B cell monoclonal antibody and chemotherapy, but the prognosis was worse than that of LCD.

CONCLUSIONSCastleman's disease is rare in children, which can be misdiagnosed because it has no specific manifestations. The prognosis depends on the subtype.

Objective To explore the determinants of Alzheimer' s disease (AD) patients with depression.Methods The degree of depression on AD patients was assessed by the geriatric depression scale.Improved cumulative logistic regression (ICLR) was used to analyze the determinants of AD patients with depression.Results 196 AD patients were investigated.Among the 196 AD patients,there were 60(30.6％ ) males and 136(69.4％ ) females,at 58-89 years of age (72.3 ± 6.0).Physical activity,diabetes,MoCA,hearing,economic sources and alcohol were related to the degree of depression of AD patients (P＜0.10 ).The difference between “normal” and “mild depression” was smaller than difference between “mild depression” and “severe depression”.Conclusion AD patients with mild depression were the target population for prevention and they were influenced by several factors listed above.

Objective：To investigate the mechanism of increased glucose uptake, the expression of myoc ardial glucose transporter1 (GLUT1) was determined after low-flow myocardial is chemia. Methods： An in vivo open-chest canine model of low -flow myocardial ischemia was used to correlate myocardial glucose uptake with the number of GLUT1. The expression of myocardial GLUT1 glucose transporter was determined by semiquantitative Northern blotting and immunoblotting. Res ults： GLUT1 mRNA and GLUT1 polypeptide expression was substantially inc reased in ischemic region from the experimental hearts when compared to normal h earts. There was no significant regional difference in GLUT1 expression in eith er normal or ischemic hearts.Conclusion：Myocardial ischemia ind uces a factor or factors which stimulate GLUT1 expression in ischemic myocardial regions. Enhanced GLUT1 expression may be an important protective mechanism by which myocardial cells enhance glucose uptake and metabolism during low-flow my ocardial ischemia.

Objective: To investigate whether there is additi ve effects of hyperinsulinemia and ischemia on expression of canine myocardial G LUT4 gene in vivo. Methods: The expression of myocardial GLU T4 was determined by semiquantitative immunoblotting.The expression of GLUT4 mRN A was determined by semiquantitative Northern blotting. Results: Dramatic changes were seen in GLUT4 mRNA and GLUT4 expression in the ischemic hearts.After infusing insulin for 8 h,regional GLUT4 mRNA and GLUT4 levels in is chemic hearts were 2.5, 2.3-fold that of expression in normal hearts(P<0.01 ). Myocardial glucose uptake in ischemic hearts was increased by 4-fold when co mpared with normal hearts(P<0.01). Conclusion: There are not only additive effects of hyperinsulinemia and low-flow ischemia on canine myoc ardial GLUT4 mRNA and GLUT4 expression in vivo, but also increase of myocar dial glucose uptake. Enhanced GLUT4 expression may be an important protective m echanism by which myocardial cells enhance glucose uptake and metabolism during low-flow ischemia.

Objective: To observe the effect of L-carniti ne (L-CN) in the treatment of congestive heart failure (CHF). Meth ods: Fifty-six cases of chronic CHF randomly received routine treatment (Digitalis, diuretics, vasodilator, ACEI or βblocker) or L-CN (3.0 g/d ,V D×10 d) with routine therapy. Results: The treatment efficiency of L-CN group and control group were 89.3% and 60.7% (P<0.01), respect ively. No adverse reactions related to the drug were observed. Conclusio n: L-CN with routine therapy might be a safe way to the treat CHF.
