Devices and services are the most basic elements of assistive technology, and the professionals training and study are the drive for the development of high quality of assistive technology;social consciousness, policies and laws which focus on the independence and social participation of people with disabilities are key elements and necessary social backgrounds. Assistive technology products will have good markets only if people with disabilities can afford them and have an environment in which they can use them. The component ele-ments of assistive technology field will enhance each other only when assistive technology products can be widely used.

Global ischemia model was produced in rabbit by occluding bothvertibral and common carotid arteries. During brain ischemia the onset and peaklatencies of SEPs gradually increased, the amplitudes became lower, till all wavesdisappeared. After reconstruction of brain blood flow the latencies decreased andthe amplitudes increased to the control level. CDP-choline improved the recoveryof SEPs caused by brain ischemia obviously.

The paper studied legislation, policies, government participation through investigations and internet resources and has a complete cognition of assisitive devices condition in Canada. Canadian Federal Government encourages, guides and participates in assistive technology exploiting based on non-discrimination legislation. Assistive technology service system has been running well in social consciousness,funding, quality and varieties of assistive devices, professional service, necessary social environment and public service.

The assistive devices for children with cerebral palsy are various to meet the special needs, which involve position, mobility,communication, education, career, etc. It tends to be accurate function and a variety of functional integration in position and mobility products.Various series of augmentation alternative communication device have been developed. A large number of assistive technology products have been developed in education, independent live, social skill and therapy fields, and Apps are the important components among them. Various techniques of information and switch have been applied, which may revolutionize the assistive industry.

This article introduced the methods and skill by the procedure about consideration of assistive technology in the individualized　educational program (IEP) under the SETT framework, including considering a student's need for assistive technology, gather information　of the student, assessing and matching of assistive technology, solution generation, documenting the solution in the IEP, implementation　plan. The Quality Indicators for Assistive Technology Services (QIAT) and the people component of the IEP team were also introducd in the　article.

This paper introduced the key right of people with disabilities for assistive technology under the U.S. laws, including The Rehabilitation Act, Individuals with Disabilities Education Act, Assistive Technology Act and Americans with Disabilities Act. The assistive technology right involved occupation rehabilitation, employment and education and public area. The related agency needs to respond to these requirement. China can learn some from these acts.

Objectives:To understand the human resources and costs of essential public health services based on community health service centers in Beijing’s rural areas and to offer policy recommendations for advancing the progress of essential public health services. Methods:With the self-designed questionnaire, the paper collected data from the districts of Changping, Tongzhou, Huairou and Miyun. By cluster random sampling, 12 community health service centers and 108 personnel were surveyed based on the level of economic development. Results: The number of young women, preventive personnel and staff with low ranking positions represents a significant share of all essen-tial public health service providers. Beijing’s rural areas deploy a great deal of human resources for vaccination and health education with little set aside for women’s health and reproductive health. The unit cost of setting special col-umns for health education and field disease treatment is higher than other service items. The suburbs deploy a great deal of human resources for service items than the outskirts while the unit costs are lower. Conclusions: Human re-source for essential public health services in Beijing’s rural areas should be strengthened. The costs of service items differ greatly so that policy adjustments and finances should be implemented based on actual demand and resources.

The establishment animal model of Graves’ disease contributes to the study of etiology, pathogenesis and therapeutic modalities. After decades of studies and making improvements, the method of building mice model of Graves’disease has achieved a great development. Although there were many reports of animal model building in Graves’disease, as a mature technology A-subunit of thyrotropin receptor( TSHR)-expressing adenovirus was used to establish Graves’disease mice model, which has been accepted widely because of its high efficacy.

Objective To investigate the effect of extraction of radix isatidis on the expression of transforming growth factor(TGF-β)in lung tissues of rats with radioactive lung injury.Methods 72 female Wistar rats were randomly divided into 3 groups,blank control group(groupA,n=24),simple irradiation group(group B,n=24),irradiation with Chinese medicine group(group C,n=24).Rats in group A and group B were given distilled water 2 mL/200g by gavage for one week,the rats in group C were given extraction of radix isatidis 2 mL/200g(1.6 g/200 g)per day for one week,then the rats received irradiation,during irradiation,the rats' weight was measured once a week,to illuminate the end.After 10-time irradiation(the 30th day), and at 60 days and at 120 days after irradiation,the expression levels of TGF-βin lung tissue were detected;In addition each rat lung tissue morphology was observed.Results The expression levels of TGF-βprotein in group B reached peak at the 30 days after irradiation,which at different time points in group A and group C was significantly lower than that in group B(P<0.01).Rats of group A had no significant change in lung tissue.Rats of group B were observed inflammatory cells in interstitial pulmonary alveolar,alveolar structural damaging,interstitial pulmonary edema,interstitial hemorrhage and inflammatory pulmonary with alveolar cavity;Rats of group C pulmonary interstitial fewer inflammatory cells in alveolar damage were not obvious, with no-pulmonary interstitial edema, hemorrhage and no inflammatory symptoms, comparison between group B and C was not obvious. Conclusion Extraction of radix isatidis could reduce the expression levels of transforming growth factor(TGF-β)in lung tissues of rats with radioactive lung injury ,has better preventive effect on radioactive lung injury,could protect lungtissue from damaging,inhibite alveolar permeability,and present the effect of pulmonary edema.
