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.

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.

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.

Objective To understand the clinical characteristics and treatment outcomes of primary gastrointestinal non-Hodgkin lymphomas (PGINHL) and analyze the differences between T-cell and B-cell lymphomas.Methods.The characteristics of 51 PGINHL patients were analyzed regarding to their clinical manifestations,diagnosis,treatments and outcomes.Results 51 cases of PGINHL meeting the WHO(2008) criteria were identified.The median age of the patients at the time of diagnosis was 56 years old and the male ∶ female ratio was 1.44∶1,35 cases (68.7 ％) had B-lineage and 16 cases (31.3 ％) had T-cell lineage lymphomas.Compared to those with B-cell lymphoma,patients with T-cell lymphoma presented with a greater incidence of such symptoms as hematochezia,diarrhea and night sweating (P ＜ 0.05).After eliminating MALT lymphoma,prognosis of T-cell lymphoma and B-cell lymphoma had no significant difference.Conclusion In PGINHL cases,B-cell lymphomas appeare to be more common and have better prognosis than T-cell lymphomas.

Job Accommodation of American is effective to ensure the equal employment of domestic disabilities. This paper introduced its legal basis, contents and procedures.

There is a huge gap in the quality of assistive technology (AT) service between China and the USA. In the USA, the certification of Assistive Technology Professional （ATP） has been used to supervise the development of AT service, while China is at the beginning of AT service. The current situation and the effects about the certification of ATP, how to get the ATP, the requirements someone must have were discussed in the paper.
