Objective To investigate the cognition about rehabilitation among parents having retarded children aged 0～6 in Beijing. Methods237 retarded children diagnosed in Disabilities Sampling among 0～6 Years Children in Beijing in 2004 were followed up 3 years later, and their parents were investigated with questionnaire about their rehabilitation knowledge. Results25.99% of these children had received rehabilitation services in the 3 years at least once, and was higher in city than in country. 38.39% and 16.52% of their parents knew their children need early rehabilitation and family training. ConclusionIt is necessary to communicate the knowledge of rehabilitation to the parents of retarded children.

Objective To understand the prevalence situation of disabled children with autistic spectrum disorders (ASD) in China. Methods The data of disabled ASD children aged 0~17 years from the Second National Sampling Survey on Disability was selected and analyzed. Results The prevalence rate of disabled ASD was 0.212 among children aged 0~17 years in China, the prevalence rate of disabled ASD among boys (0.282‰ ) was higher than that among girls (0.132‰ ) (χ2=16.119, P=0.000). The prevalence rate of disabled ASD was higher in younger group than that in elder group (P=0.000). There was no significant difference in the prevalence rate of those children between city and countryside (χ2=0.093, P=0.760). There were 73.3% disabled ASD children received rehabilitation training and service, and 26.7% disabled ASD children didn't. Conclusion Disabled ASD children is a big group in China, and their rehabilitation, education, and care after grow-up are badly in need of social attention.

Objective To investigate the correlation between developmental function and pathological behavior in children with autism. Methods A total of 154 children with autism were tested with Revised Chinese Version Psycho-Educational Profile (C-PEP) during 2011 to 2014. Results The scores of fine movement, hand-eye coordination, and oral language of developmental function were lower in the girls than in the boys (t>2.120, P<0.05). Among the children with autism aged 2-7 years, the developmental function was better in the older group than in the younger group (P<0.05);however, it was not better in the children aged 8-10 years and>10 years than in those aged 6-7 years. There was no difference in the scores of pathological behavior between the girls and the boys (P>0.05). Some pathological behaviors were milder in the older group than in the younger group (P<0.05). The scores ofP(pass) in developmental function were positively correlated with the scores ofA(absence) in pathological behavior (P<0.01), and negatively correlated with the scores ofS(severe) in pathological behavior (P<0.01). The scores ofF(fail) in developmental function were negatively correlated with the scores ofA(absence) in patho-logical behavior (P<0.01), and positively correlated with the scores ofS(severe) in pathological behavior (P<0.01). Conclusion Develop-mental function of children with autism is highly correlated with pathological behavior, and the rehabilitation and education of children with autism aged above 7 years should be concerned.

Objective To follow up the rehabilitation, education, and assistive devices utilization of school age children with cerebral palsy. Methods From 2012 to 2015, 80 children with cerebral palsy were called their parents with telephone and filled in the questionnaires. Results 69 children (85.25%) continued to receive rehabilitation, 11 children (13.75%) stopped rehabilitation. 42 children (56.25%) received education in ordinary schools, 15 children (18.75%) received education in special schools, 4 children (5.00%) were nursed in nursing institu-tion, 16 children (20.00%) stayed at home and did not receive any education. The main problem and needing at present were receiving reha-bilitation, receiving school education, relief the rehabilitation cost of more than one institution, etc. 61 children (76.25%) ever applied for as-sistive devices, 19 children (23.75%) did not. The feedback of application process in order were smoothly;applied, but didn't get;the assis-tive devices that received was inappropriate. 29 children (73.75%) needed assistive devices currently, 21 children (26.25%) did not. When asked the category of needed assistive devices at present, 19 parents (20%) answered that they did not know the category of assistive devices well or they did not know which kind of assistive devices they needed. Conclusion It is important to provide quality and quantity rehabilita-tion and education service, popularize the knowledge of assistive devices and their clinical application for cerebral palsy children. Assistive devices providing departments should do more communication with cerebral palsy children and their parents, in order to reduce the waste of resources, and increase the rational use of resources, and provide more benefits for children with disabilities.

Objective To investigation the condition,expectation and support of quality of life in adult with intellectual disability.MethodsA total of 394 adult with intellectual disability,their parents and friends in Beijing were involved in the study.Their qualities of life were evaluated.ResultsAbout quality of life,the adult with intellectual disability had significant more expectation than they had gained actually;their parents and friends had significant more expectation than themselves and staff of primary rehabilitation did.ConclusionIt is necessary to provide support to improve the quality of life of adult with intellectual disability.

Objective To analyze the social and family factors influencing rehabilitation of mental retarded children.Methods 237 children diagnosed as mental retardation in 2004 in Beijing were researched with Self-designed Questionnaires and data were analyzed by Cross-tabs and Logistic Regression statistical method.Results The analysis showed that the degree of disabilities (P<0.001), education received (P<0.05), and the attitude from community to these children (P<0.05), were factors influencing rehabilitation of mental retarded children.Conclusion The degree of disabilities is the most important influencing factor to rehabilitation of mental retarded children; the mild or moderate mental cases can get good rehabilitation in a better community and family environment. The attitude to these children from community can make a great help to the rehabilitation.

Objective To explore the outcome of children with mental retardation after 3 years follow-up. Methods The subjects were 237 children with mental retardation, selected from Beijing Municipal Investigation for Children with Disability in 2004. Gesell Developmental Schedule and Wechsler Intelligence Scale for Children were used to estimate the children's intelligence. Results After 3 years, the outcome showed non-mental retarded, 124 subjects (52.32%); mild mental retarded, 46; moderate mental retarded, 32; severe mental retarded, 16; profound mental retardation, 19. The related factors include urban/suburban (B=-0.622), parental knowledge about rehabilitation training (B=-0.470) and score of personal social interaction in Gesell Test(B=-0.040). Conclusion The outcomes of children with mental retardation are different. But some problems still exist even in non-mental retarded children.

Objective: To compare the molecular weight of sodium hyaluronate in the injection determined by three methods. Methods:Viscometry was used to determine the molecular weight of sodium hyaluronate. The molecular weight and its distribution ( Mw/Mn) was measured by size exclusion chromatography ( SEC) and the combination of multi-angle laser light scattering instrument and size exclusion chromatography( MALLS-SEC) . Results:The results of MALLS-SEC were close to those of viscometry, and Mw/Mn was obtained simultaneously. The average value of molecular weight of three batches of samples was 991962, 1007438 and 990232 with RSD of 6. 5%, 4. 6% and 2. 2%, respectively(n=4). The average value of Mw/Mn was 1. 6, 1. 6 and 1. 6 with RSD of 7. 2%, 3. 2% and 3. 2%, respectively(n=4). Conclusion:MALLS-SEC shows better accuracy and precision, and can be used in the quali-ty control of sodium hyaluronate samples.

Objective To explore the 3D gait analysis of stroke hemiplegic patients. Methods 28 stroke hemiplegic patients were examined with the 3D gait analysis system before and after 6-week rehabilitation. Results After rehabilitation, support phase time of the affected lower limb increased and swing phase time decreased (P<0.05). Step length, stride length and walking speed increased (P<0.05). There was significantly difference in range of motion (ROM) of hip deduction/abduction, flexion/extension, and knee flexion/extension, and ankle internal/external rotation, varus/eversion, dorsiflexion/plantar flexion before and after rehabilitation (P<0.05). Conclusion 3D gait analysis system can evaluate the patient's gait objectively and quantitatively, and provide the basis for rehabilitation assessment.
