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.

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.

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.

Positive and meaningful exploration was conducted by related teachers to improve the teaching quality of oral clinical pharmacology.Case based teaching method was applied in the teaching of adverse reactions and bilingual teaching was employed in the teaching of local anesthesia.Correlation and comparison of the key knowledge points were emphasized in the teaching process. Students′ interests were aroused and satisfactory results were achieved through implementing these measures.

An innovative approach,named associating liver partition and portal vein ligation for staged hepatectomy (ALPPS),has made possible a marked increase in future liver remnant (FLR) over a short period of time,and has challenged the concept of unresectability.To date,ALPPS has been employed for a variety of primary and metastatic liver tumors from many centers across the world.Many technical variations of ALPPS have been described.However,much controversy has surrounded this procedure,and many problems remain to be solved,such as the reasons for rapid hypertrophy,the technical feasibility,safety and long-term oncologic outcomes,and the result compared with the conventional two-stage hepatectomy.These aspects are needed to be evaluated further in large-scale studies.We believe that the ALPPS procedure will has much room for further development.

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.
