ObjectiveTo delineate imaging findings using an imaging platform and investigate the correlation between MRI characteristics of spinal cord atrophy and clinical diagnosis in children with spinal cord injury (SCI). MethodsImaging data of 150 children with SCI admitted to Beijing Bo'ai Hospital, China Rehabilitation Research Center, from January, 2002 to March, 2024 were collected and imported into the imaging platform. The anteroposterior and transverse diameters of the middle part of the spinal cord at the cross-section with the most severe atrophy were measured, and the relevant indicators of the previous normal spinal cord segment were measured as controls; the radiomic features were extracted. Clinical data of the children including gender, age, cause of injury, sensory level, motor level, spinal cord injury level, injury severity and disease course were collected. ResultsSpinal cord atrophy was identified in 81 cases (54%), among which 78 cases (96%) were American Spinal Injury Association Impairment Scale (AIS) grade A and 3 cases (4%) were AIS grade C. The upper boundary of the spinal cord atrophy site strongly correlated with the injury level, motor level and sensory level (r > 0.8, P < 0.001). ConclusionMore than half of children with SCI may develop secondary spinal cord atrophy, the vast majority of whom suffer from complete spinal cord injury; the upper boundary of spinal cord atrophy is correlated with the injury level.

Objective To compare six existing Chinese standards related to visual disability,including Disability Assessment and Code for Life Insurance(Insurance Standard),Specification for Ability Assessment of Older Adults(Elderly Stan-dard),Grading of Disability due to Human Body Injury(Judicial Standard),Standard for Identify Work Ability—Gradation of Disability Caused by Work-related Injuries and Occupational Diseases(Work Injury Standard),Standard for Assessment of Disability Grades of Military Personnel(Military Standard),and Classification and Grading Criteria of Disability(Disability Classification Standard).Methods Based on the theoretical framework of International Classification of Functioning,Disability and Health(ICF)and International Classification of Diseases,the 11th Revision(ICD-11),and with reference to World Report on Vision(WRV),this study analyzed and compared five key dimensions of visual disability across the six stan-dards:definition,classification,grading,assessment methods and coding systems.Results In terms of definition,the insurance,work injury,military,and disability classification standards emphasized vi-sual structure and function,focusing on visual acuity and visual field;the insurance and elderly standards incor-porated activities and participation,reflecting the concept of functional vision;the judicial standard lacked a dedi-cated definition of visual disability.In terms of grading,each standard graded visual disability into different lev-els acoording to different functional indicators.In terms of coding,only the insurance standard adopted the ICF framework,while others used non-ICF numeric codes or lacked standardized coding.In terms of assessment tools,the elderly standard employed a customized perceptual and participation scoring system,while others re-lied primarily on vision charts.Conclusion Most current Chinese standards focus on impairments in visual function,with limited attention to activity limitations and participation restrictions.It is needed for incorporating the concept of functional vision,aligned with ICF and WRV,to establish a unified conceptual framework,terminology,coding system for visual disability,and comprehensive assessments that reflect not only impairments but also the impact on daily functioning and en-vironmental interaction.

Objective To compare six representative Chinese standards related to hearing disability in terms of conceptual frame-works,definitions,classification,grading and assessment.Methods Using the framework of International Classification of Functioning,Disability and Health(ICF),World Health Organization Disability Assessment Schedule 2.0(WHODAS 2.0),International Classification of Diseases,Elev-enth revision(ICD-11),and World Report on Hearing(WRH),six national standards,such as Disability Assess-ment and Code for Life Insurance(Insurance Standard),Specification for Ability Assessment of Older Adults(El-derly Standard),Grading of Disability due to Human Body Injury(Judicial Standard),Standard for Identify Work Ability—Gradation of Disability Caused by Work-related Injuries and Occupational Diseases(Work Injury Stan-dard),Standard for Assessment of Disability Grades of Military Personnel(Military Standard),and Classification and Grading Criteria of Disability(Disability Classification Standard),were analyzed in dimensions of defini-tions,coding systems,classification and grading methods,and assessment approaches.Results In terms of definitions,Insurance Standard was relatively comprehensive,covering the dimensions of body func-tion,activities and participation in ICF,which was consistent with the definition of functional hearing in the WRH.Elderly Standard focused on body function.Judicial,Work Injury and Military Standards were more in-clined to physiological damage,emphasizing auditory structure and sensory functions.Although Disability Clas-sification Standard covering dimensions of activities and participation,it did not elaborate on functional out-comes.In terms of classification and grading,different from the WRH's recommendation of 20 dB HL as the stan-dard for hearing impairment,most of the six standards still used 40 dB HL or above as the threshold.For grading levels,Insurance Standard had nine grades,while Judicial,Work Injury and Military Standards had seven grades,Elderly Standard had three grades,and Disability Classification Standard had four grades.The basis for grading relied more on physiological measurements rather than functional performance.In terms of coding systems,only Insurance Standard referred to ICF codes,while the others mostly used self-defined numerical sequences or grade codes.In terms of assessment methods,the WRH advocated a comprehensive assessment integrating auditory ability,self-reports and participation restrictions.However,currently,only Elderly Standard involved subjective sensory scoring,and the others still mainly relied on objective methods,such as pure-tone audiometers,lacking assessment dimensions for social participation and environmental factors.Conclusion Hearing disability should be defined from three levels:hearing structure and function,activity and participa-tion,and environmental factors.However,China's six standards adopt different definitions,classifications,grad-ing systems and assessment methods due to their varying purposes and application scenarios.The majority of these standards are primarily based on body function,specifically hearing loss.Future standards for hearing dis-ability need to consider the introduction of the concept of functional hearing,to determine hearing loss and its im-pact on activity and participation.

Objective To systematically compare five physical disability-related standards widely used in the fields of insurance,work related injury,forensic appraisal,and disability evaluation.The comparison covers definition,coding,classi-fication,grading,and assessment methods to reveal each standard's framework and methodology,and to provide evidence for integrating and optimizing physical disability standards.Methods Based on International Classification of Functioning,Disability and Health(ICF)and International Classifica-tion of Diseases,11th Revision(ICD-11),we analyzed and compared five physical disability-related standards,including Disability Assessment and Code for Life Insurance(Insurance Standard),Grading of Disability due to Human Body Injury(Judicial Standard),Standard for Identify Work Ability—Gradation of Disability Caused by Work-related Injuries and Occupational Diseases(Work Injury Standard),Standard for Assessment of Disability Grades of Military Personnel(Military Standard),and Classification and Grading Criteria of Disability(Disabili-ty Classification Standard).We examined definition,coding systems,classification,grading scales and assess-ment.Results According to the ICF framework,at the level of body functions and structures,physical disability mainly in-volved neuromusculoskeletal and movement related functions(b7),including joint and bone functions(b710-b729),muscle functions(b730-b749),and movement functions(b750-b789).At the activities and participation level,it primarily concerned mobility(d410-d499)and self care(d510-d599).Related conditions were commonly found in Certain infectious or parasitic diseases(01),Diseases of the nervous system(08),Diseases of the muscu-loskeletal system or connective tissue(15),Developmental anomalies(20),and Injury,poisoning or certain other consequences of external causes(22),etc.Among the five standards,only Disability Classification Standard ex-plicitly defined physical disability,yet its terminology did not followed ICF categories.Regarding coding,only the Insurance Standard adopted ICF codes;and the other four used self devised coding systems.The sub catego-ries in these physical disability standards did not fully cover all ICF categories relevant to physical disability.In terms of grading,Disability Classification Standard used a four level grading,whereas the other four standards employed ten level grading.Concerning assessment,all five emphasized evaluation of body structures and func-tions and involved daily activity capacity;however,WHO Disability Assessment Schedule(WHODAS 2.0)for comprehensive functional assessment,had not been proposed for evaluation of general functioning.Conclusion China has developed different physical disability standards to meet diverse needs.There are differences in definition,structure and content.It is necessary to revise and refine the relevant components of physical disabili-ty,including definition,classification,grading,coding and assessment,based on ICF and ICD-11,and to intro-duce WHODAS 2.0 as a comprehensive functional assessment tool.

AIM: To compare the effectiveness of foldable capsular body(FCB)with traditional scleral buckling(SB)in the treatment of experimental retinal detachment animal models.METHODS: After successfully establishing rhegmatogenous retinal detachment(RRD)animal models, 24 New Zealand white rabbits were randomly divided into three groups(RRD models group, SB group, and FCB group), with 8 rabbits in each group. The FCB and SB groups underwent SB and FCB surgeries for the RRD animal models, while the RRD models group only consists of RRD models without any surgical intervention during the follow-up period. The follow-up duration was 3 mo. Wide-field neonatal fundus imaging system and ophthalmic B-ultrasound were used to assess the fundus conditions before and after surgery. The Icare® TONOVET Plus tonometer was utilized to evaluate intraocular pressure changes before and after surgery. The Eaton and Draize scoring systems were selected to monitor postoperative inflammatory reactions.RESULTS: The retinal reattachment rates in the FCB and SB groups were 87.5% and 75.0%, respectively, with no statistically significant difference between the groups(P>0.05). The intraocular pressure in both the FCB and SB groups increased postoperatively compared to preoperative levels(P<0.01), and there were no significant differences in intraocular pressure at any time points during the follow-up period between the groups(P>0.05). The intraocular pressure in the RRD models group remained at a low level throughout the follow-up period. The average surgical time for the FCB group was 16.87±2.29 min, which was shorter than 46.25±4.74 min in the SB group(t=-15.166, P<0.001). According to the Eaton and Draize scoring systems, the FCB group had lower grades of conjunctival hyperemia and edema in the early postoperative period compared to the SB group, indicating milder inflammatory reactions(P<0.05).CONCLUSION: Both FCB and SB are effective in treating experimental RRD. Compared to SB, FCB is simpler to operate, and also has a shorter surgical time and milder postoperative inflammatory reactions.

Objective:To investigate the characteristics of resting-state mirror homotopic connectivity and the gray matter volume of brain in patients with neuropsychiatric systemic lupus erythematosus (NPSLE).Methods:From June 2020 to March 2023, a total of 35 NPSLE patients (NPSLE group) and 30 non-NPSLE patients (non-NPSLE group) were selected from Taizhou People's Hospital Affiliated to Nanjing Medical University, another 31 healthy volunteers were recruited as the healthy controls(HC group). All participants underwent resting-state functional magnetic resonance imaging (rs-fMRI) and mini-mental state examination (MMSE) assessments. The patients in NPSLE and non-NPSLE groups were additionally assessed using the fatigue scale for motor and cognitive functions (FSMC) and the hospital anxiety and depression scale (HADS).The DPABI V7.0 toolkit based on the MATLAB platform was used to preprocess the rs-fMRI data and calculate the voxel-mirrored homotopic connectivity(VMHC) indexes, and the differences in VMHC between groups were evaluated by covariance analysis in SPM12.0 software, and the VMHC values of brain regions with significant differences were extracted for further comparison between the two groups.Partial correlation analysis was performed to investigate the association between VMHC values and clinical parameters in NPSLE patients.The brain regions with significant differences between NPSLE patients and non-NPSLE patients were used as region of interest (ROI), and gray matter volumes within these ROIs were then calculated by VBM8 toolbox.Results:(1)There were statistically significant differences in the VMHC values of bilateral precentral gyrus, bilateral dorsolateral superior frontal gyrus, bilateral medial and paracingulate gyrus, bilateral parahippocampal gyrus, bilateral middle occipital gyrus, bilateral postcentral gyrus, and bilateral superior temporal gyrus among the 3 groups( F=11.246-14.102, all P<0.05). The NPSLE group exhibited significantly lower VMHC values in these regions compared to both the non-NPSLE group and HC group (all P<0.05), but there were no significant differences in these regions between the non-NPSLE group and HC group (all P>0.05).(2) The gray matter volumes of bilateral dorsolateral superior frontal gyrus(right: (0.57±0.11)mm 3, (0.65±0.08)mm 3, t=-3.409, P=0.001; left: (0.53±0.10)mm 3, (0.60±0.07)mm 3, t=-3.082, P=0.003), bilateral precentral gyrus(right: (0.32±0.06)mm 3, (0.35±0.04)mm 3, t=-2.044, P=0.045; left: (0.39±0.06)mm 3, (0.42±0.04)mm 3, t=-2.505, P=0.015), right medial and paracingulate gyrus((0.66±0.08)mm 3, (0.70±0.07)mm 3, t=-2.491, P=0.015) and left superior temporal gyrus((0.57±0.09)mm 3, (0.61±0.06)mm 3, t=- 2.344, P=0.022) in the NPSLE group were smaller than those of non-NPSLE group.(3)Correlation analysis showed that the VMHC value of dorsolateral superior frontal gyrus was positively correlated with IgA level in NPSLE patients ( r=0.353, P=0.047). Conclusion:Patients with NPSLE generally have decreased mirror homotopy functional connectivity in the cerebral hemispheres, accompanied by a decrease in gray matter volume in some brain regions, which can provide a certain neuroimaging basis for the pathogenesis of brain injury.

Objective Based on the theoretical framework of International Classification of Functioning,Disability and Health(ICF),this paper compared the classification and grading methods of disability standards in four areas in China,focusing on definition,classification,grading,coding systems and assessment tools.Methods Four disability standards including Disability Assessment and Code for Life Insurance(insurance standard),Classification of Disability Degrees for Human Body Injury(judicial standard),Grading of Disability for Work-Related Injuries and Occupational Diseases(work-related injury standard),and Classification and Grading of Dis-abilities for Persons with Disabilities(disability eligibility standard)were systematically analyzed.Each standard was reviewed to identify core elements of disability definitions,classification,and grading methods.Content analysis was used to extract and compare the definitions,classification,grading,coding systems,and assessment tools.The strengths,weaknesses,and practical limitations of each standard were analyzed using the ICF frame-work.Results There were different in disability definitions,classification and grading,coding systems,and assessment tools across the standards.In terms of definitions,the insurance standard emphasized ICF's body structure and function impairments;the judicial standard defined disability as limitations in life and work capacity due to bodily injury,covering ICF's body structure and function,activity and participation;the work-related injury standard focused on loss of labor capacity due to work-related injuries,involving body structure and function,activity and partici-pation;the disability eligibility standard refered to the ICF model,defining disability as impairments in body function and structure,and activity limitations and participation restriction.Regarding classification and grading,the insurance standard divided disabilities into eight categories based on body structure and function,with ten grades of disability severity;the judicial standard first graded disabilities into ten levels and then classified as in-jury site;the work-related injury standard divided disabilities into five categories based on clinical disciplines,grading from one to ten;the disability eligibility standard divided disabilities into seven categories,each with four grades.For coding systems and assessment tools,the insurance standard used ICF coding system,while the disability standard for persons with disabilities used a numerical coding system other from ICF,and the other standards did not use coding systems.Assessment tools varied significantly.The use of World Health Organiza-tion Disability Assessment Schedule(WHODAS 2.0)was proposed but not applying it in grading.Conclusion This study has systematically compared and analyzed four typical disability-related standards in China using the ICF framework.Personal Insurance Disability Assessment and Coding,Grading of Disability Caused by Bodily Injury,and Classification and Grading of Disabilities for Persons with Disabilities are all promulgated af-ter 2011,and adopt ICF concepts and methods to define and classify disabilities,considering body function and structure,activity and participation,and environmental factors.However,due to different purposes,their grading methods and levels vary:except for Classification and Grading of Disabilities for Persons with Disabilities,which uses a four-level grading system,the other standards use a ten-level system,primarily based on body func-tion and structure.In disability assessment,the recommended methods differ by category,showing significant variability.Due to differing classification and grading methods,disability data from various standards are lack in comparability.The international trend advocates for a unified disability standard framework based on ICF and ICD-11 to enhance the comparability and exchangeability of disability data.
