Discharge planning is the basis of continuous medical service. It could shorten the length of hospital stay, improve bed occu-pancy, reduce readmission rate, save medical costs, and improve the quality of life. It's considered to be important and supplemented by rele-vant policies and regulations to promote development in the United States, the United Kingdom, Canada, Australia and other developed countries. In China, even though Hong Kong and Taiwan have issued discharge planning policies, the mainland is still at the stage of explora-tion. Discharge planning in Chinese mainland has problems like restricted objectives, imperfect content, un-optimized process, unestablished professionals and organizations and so on. Standardized discharge planning guide still needs further research. As the health service system including hospitals, public health institutions and primary health institutions coverd urban and rural gradually, and the new pattern of grad-ing diagnosis and treatment established, it's necessary to analyze the necessity, importance, obstacles and measures of discharge planning in China.

With the social development and the transformation of medical model, providing patients with continuous services and seam-less transfer between different medical institutions, namely continuity care, is inevitable. Discharge planning take patients as the center and patient's needs as the guidance. Patients and their families should actively take part in the plan. Through multi-disciplinary and multi-institu-tional cooperation, patients can continue to enjoy health services after discharge. Discharge planning is the basis of continuous medical ser-vice. This article summrized the background and situation of discharge planning in the United States, Canada, Brazil, the United Kingdom, Ireland, Australia, Japan, India, South Africa, and Hong Kong, Taiwan and mainland in China. When heavy medical burden, aging, im-balence between supply and demand occurred, discharge planning could be helpful to make rational use of medical resources, save medical costs, guarantee the quality of medical service continuity, avoid the occurrence of adverse events after discharge and improve the patients' function and quality of life. This article reviewed group members, time, institutions and process of discharge planning in order to provide ev-idence-based basis for the development of discharge planning in China.

Either injury or reconstruction of anterior cruciate ligament (ACL) may damage proprioceptive sense, remodel central ner-vous system and impair motor control. It is necessary to systematically remodel neuromuscular function, including proprioceptive sense cor-rection, central nervous system remodeling and motor control strengthening etc., for patients after ACL reconstruction.

Objective To understand the causes of injury and levels of disability of patients with traumatic spinal cord injury and explore the related factors with the levels of disability. Methods Literature review and experts panel advice were used to collect the related factors. The questionnaire "Survey on Related Factors of Disability Levels of Patients with Ttraumatic Spinal Cord Injury" was designed for the data collection, including the causes of injury, being conscious or not, protection of the injured areas, tools for transportation, the time getting first aid, levels of emergency hospitals and the time of first spinal surgery. From October 2010 to March 2011, 260 inpatients with traumatic spinal cord injury were surveyed by the well-trained researchers. Results 107 patients(41.2%) were caused by traffic accidents, 69 (26.5%) were caused by falls, 60 (23.1%) by crash, 6 (2.3%)by sports injury, and 18 (6.9%) by other reasons. The results of the extent and the levels were that complete paraplegia take up 41.15%, complete tetraplegia take up 25.38%, incomplete tetraplegia take up 18.08%, incomplete paraplegia take up 15.39%. There were significant differences in the causes of injury between the different extent and levels of injury (P<0.05). There were significant differences in levels of injury between the different extent of injury (P<0.05). Significant differences were existed in the levels of injury among being conscious or not, protection of injured areas during transportation and the secondary transportation (P<0.05). Whereas, no significant difference was observed among protection in the injury site, tools for transportation, the time getting first aid, the levels of emergency hospitals and the first time of spinal surgery between the different extent of injury(P>0.05). Conclusion Not only the causes of injury, but also the protection of injured areas, high frequency of secondary transportation are responsible for the extent of injury and levels of injury in individuals with traumatic spinal cord injury in China.

Objective To explore the feasibility and effectiveness of lateral gastrocnemius muscle branch nerve transferring for deep pe-roneal nerve injury. Methods Thirty-two adult female Sprague-Dawley rats were divided into control group (n=8), sham group (n=8), nerve direct repairing group (n=8) and nerve transferring group (n=8). Twelve weeks after the anastomosis, the nerve anastomosis was observed vi-sually, the length of lateral of gastrocnemius muscle branch (L1), the diameter at the point of entering muscle (D1), the maximum detachable length of nervus peroneus communis (L2), the diameter of deep peroneal nerve (D2) and the distance between branch point and neck of fibu-la (S) were measured. The peroneal nerve functional index (PFI), the amplitude of compound muscle action potential (CMAP), nerve con-duction velocity (NCV), the weight of the tibialis anterior and the creatine kinase (CK) activity of theanterior tibial were compared among groups. Results L10.05). Conclusion It is feasible that lateral head muscular branches of gastrocnemius nerve transferring can repair deep peroneal nerve injury, which is needed to separate superficial peroneal nerve and deep peroneal nerve in the epineurium without damaging nerve for tension free neuroanastomosis. Lateral head muscular branches of gastrocnemius nerve transferring can repair the func-tion after deep peroneal nerve injury.
