Lower extremity exoskeleton system is a kind of human-machine robot, which combines the artificial intelligence with the power of mechanism. Recent years, the field of lower extremity exoskeleton robots have rapidly evolved and development of relevant technologies have dramatically increased these robots available for facilitating human walking function that could only be imagined a few years ago. Some technologies are so new that they lack the scientific evidence that would justify their use in the real setting. This paper presents an over view of design configurations, control methods and simulation test used for lower extremity exoskeleton robots. Further research efforts are required in order to incorporate many of the new technologies described in this review to promote the development of the lower extremity exoskeleton robots.

Restoring the motor function is a major goal for patients suffering from incomplete spinal cord injury (SCI), and associates with many factors, including the natural recovery and rehabilitation. The rehabilitation engineers are working to develop lower extremity exoskeleton robot that can assist gait training and recovery. Lower extremity exoskeleton robots used in walking ability reconstruction are becoming more advanced and sophisticated during the last decade. This review focuses on new application and technological progress which can be used to recover walking ability and evaluate the quality of movement after motor rehabilitation quantitatively by therapists.

Objective To observe the level of social support and self-efficacy of the breast cancer patients with postoperative chemotherapy, and study the relationship between them. Methods 76 patients were investigated with Social Support Rating Scale and Strategies Used by Patients to Promote Health (SUPPH). Results The total and every dimension scores of SUPPH and Social Support decreased in the patients. The total and every dimension scores of Social Support positively correlated with every dimension scores of SUPPH (P<0.01). Conclusion The level of self-efficacy and social support may relate each other.

Objective To analyze the epidemiological characteristics of pituitary apoplexy and investigate the changes and features of endocrine hormones caused by pituitary apoplexy.Methods A retrospective analysis of the clinical and laboratory data of pituitary tumor and pituitary apoplexy was carried out.Results (1) The incidence of pituitary apoplexy was 31.78％,patients were 15-75 (47.5 ± 11.7) year old,most patients were female.(2)Diabetes,coronary heart disease,menopausal hormone therapy,radiotherapy,surgery,and bromocriptine administration may be related to pituitary apoplexy.(3) There was high incidence of apoplexy in nonfunctioning adenoma.(4) According to the relationship between apoplexy and pituitary tumor,cases with pituitary apoplexy were divided into 5 types.(5) Pituitary apoplexy was associated with low serum creatinine,hypernatremia,hyperchloremia,hypoeosinophilia,and hypobasophilia.(6) 61.61％ of the patients had pituitary hormone deficiency,especially the GnH deficiency.(7)98.10％ of the patients were treated by surgery.Conclusion Pituitary apoplexy has its own clinical characteristics,and more attention should be paid in clinical practice.

Objective To investigate the epidemiology characteristics of spinal cord injury(SCI)in hospital.Methods1264 inpatients with SCI during April 1992～August 2006 were analyzed retrospectively.Results and Conclusion56.1% of the cases were 20～40 years old.Traffic trauma(44.3%)and fall injury(21.8%)were the main causes of SCI.The incidences of affected segments were:cervical segments 31.5%,thoracolumbar 28.1%,and thoracic 21.3%.56.7% were complete injury and 43.3% were incomplete.The most frequent complication of SCI were:urinary tract infection,pressure sore and bladder lithiasis.The expenditure of hospitalization was provided by oneself(52.5%),public medicalcare(33.1%),only 4.1% by hospitalization insurance.

Objective To compare the characteristics of traumatic and non-traumatic spinal cord injury (SCI). Methods 226 patientswere reviewed. Results 73.4% of patients were traumatic SCI, who aged (33.96± 12.18) years, younger than non-traumatic (43.98± 11.4)years; 65.4% were complete injury, more than non-traumatic 38.7%; stayed in hospital for (189.74±157.88) d, longer than non-traumatic(142.53±85.72) d; spent (55270.39±47967.59) yuan, more than non-traumatic (40838.94±34786.85) yuan. The score of activities of daily livingwhen discharged (ADL2) was (54.25±24.16), poorer than non-traumatic (74.88±25.61). Conclusion Trauma is the major cause of SCI.The patients with traumatic SCI were younger, stayed in hosptital for longer time, spent more for hospitalization, and with poor ADL2.

Cardiovascular disorders of spinal cord injury (SCI) are among the most common causes of death in individuals with SCI. The International Spinal Cord Injury Cardiovascular Function Basic Data Set is introduced in order to standardize the collection and reporting of a minimal amount of information on cardiovascular function in daily practice. Moreover, this data set makes it possible to evaluate and compare results from various published studies on cardiovascular function after SCI. The technical terms in this data set are defined in particular in this article.

Urodynamic data studying is universal for evaluating the lower urinary tract function after spinal cord injury. Urodynamic Basic Data Set for Spinal Cord Injury (SCI) is designed to standardize the collection and reporting of a minimal amount of information from the urodynamic study in daily practice in accordance with purpose and vision of the International Spinal Cord Injury Data Sets.

Collection of information on urinary tract imaging is very important for the management of individuals with spinal cord lesions. The purpose of the Urinary Tract Imaging Basic Data Set for Spinal Cord Injury (SCI) individuals is to standardize the collection and reporting of a minimal amount of information on the urinary tract imaging in daily practice in accordance with the purpose and vision of the International Spinal Cord Injury Data Sets. By studying and using the International Spinal Cord Injury Urinary Tract Imaging Basic Data Set, it is helpful to standardize and unify the collection of information on urinary tract imaging of patients with spinal cord injury in China and afford evidences to the treatment of urinary system.

Spinal cord injury(SCI)may result in tetraplegia or paraplegia,which is a great damage to the abilities of patients' daily living.There is no cure of SCI at present,and standard rehabilitation is an effective treatment method of SCI.It will help the SCI patients to develop their remaining function and potential function,prevent all kinds of complications,decrease the incidence of disabilities,improve their quality of life,shorten their stay in hospital and decrease the medical expenditure.The necessary premise of their reentry family and society is to complete the barrier free accessibilities of their housing and occupational training.
