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.

Objective Utilizing the International Classification of Functioning,Disability and Health(ICF)framework and Interna-tional Classification of Diseases,the 11th Revision(ICD-11)system,alongside evidence from World Health Or-ganization(WHO)global reports and technical reports from relevant countries,this study systematically exam-ines the definitions,classifications,grading,and assessment methods for visual,hearing,speech,physical,intel-lectual,and mental(psychiatric)disabilities.Methods Employing the ICF's biopsychosocial model,classification,and coding system and ICD-11,and referencing WHO global reports and national technical reports,this study systematically investigated the definitions,classifi-cations,grading and assessment approaches for six prevalent disabilities:visual,hearing,speech,physical,intel-lectual and mental.Results The ICF and ICD-11model and classification system offered a robust framework for defining,classifying,grad-ing and assessing disabilities.Disability definitions should address body function impairments,activity limita-tions,participation restrictions and environmental factors.The definitions,classifications and grading of visual,hearing,speech,physical,intellectual and mental disabilities aligned with ICF categories for body functions and structures,activities and participation and categories of ICD-11.Standardized tools like the WHO Disability As-sessment Schedule(WHODAS 2.0)effectively measured overall activity and participation levels.Conclusion Anchored in the ICF and ICD-11 framework,disabilities are defined,classified,graded and assessed across body functions and structure,activities and participation,and environmental factors.WHODAS 2.0 serves as a universal tool for assessing activities and participation,enabling both comprehensive functional evaluations and the conversion of results from other assessment tools.By analyzing WHO global reports and technical documents in some countries within the ICF and ICD-11 classifications framework,this study highlights global advance-ments in disability definitions,classifications,grading and assessments.Variations in disability statistics stem from differing definitions,diagnostic criteria and assessments.Disability service eligibility criteria should be tai-lored to the needs of recipients and the capacity of providers.

ObjectiveTo systematically analyze international disability data policies and standards, as well as the application of disability data in policymaking, service optimization and inclusive social development, and to clarify the importance of international disability data policies, standard systems and disability data application for the development of disability-related services. MethodsThrough the analysis of policy content and research on the data standard system, this study explored the disability data policy framework, standard system and technical path of data interoperability and integration of international organizations including the United Nations (United Nations Statistics Division and United Nations Children's Fund), World Health Orgnization, United Nations Educational Scientific and Cultural Organization, and International Labour Organization. ResultsInternational organizations established disability data policy frameworks based on their respective mandates, involving data and service development, data standards, data governance, and data application. The international community established a disability data standard system for disability data collection, coding, exchange, interoperability, statistical analysis, data fusion and application. Building a standardized disability data standard system based on the framework of international health classification standards such as International Classification of Functioning, Disability and Health, and International Classification of Diseases, Eleventh Revision would ensure the consistency of cross-national disability data policies, and the interoperability and comparability of disability data, promoting the development of data-driven disability-related services, accurately identifying the service needs of people with disabilities, and optimizing service provision, thereby improving the quality of life and social participation of people with disabilities. ConclusionThe construction and implementation of international disability data policies and data standards have promoted the standardization and interoperability of disability data. With the application of big data, artificial intelligence and blockchain technologies in disability data, international cooperation and cross-industry data fusion in the field of disability data have been promoted, further promoting the development of data-driven disability services, ensuring equal opportunities for people with disabilities to enjoy service resources, and improving the coverage and quality of disability services.

AIM:Bone morphogenetic protein 7(BMP7)reduces the expression of Yes-related protein 1(YAP1)by down-regulating Ajuba level and decreasing extracellular matrix(ECM)deposition.This study aimed to inves-tigate the influence of these factors on modifying the degree of renal fibrosis in rats with diabetic nephropathy.METH-ODS:Eighteen Sprague-Dawley(SD)rats were randomly divided into three groups:the normal control(NC)group,the diabetes mellitus(DM)group,and the DM group treated with BMP7 overexpressing adeno-associated virus(DM+rAAV-BMP7).Each group consisted of six rats.Diabetic kidney disease(DKD)was established in the DM and DM+rAAV-BMP7 groups by injecting 55 mg/kg streptozotocin(STZ)via the tail vein.NRK-52E cells were divided into three groups:the normal glucose(NG)group,the high glucose(HG)group,and the high glucose group treated with recombinant hu-man BMP7(HG+rhBMP7)group.Pathological changes in renal tissues were observed using hematoxylin and eosin(HE)and Sirius red staining.Immunohistochemical staining was performed to examine the expression sites of Ajuba and YAP1 in the renal cortex.Western blot analysis was conducted to determine the expression levels of BMP7,Ajuba,YAP1,colla-gen type Ⅲ(Col-Ⅲ),and fibronectin(FN)in the rat renal cortex and NRK-52E cells.RT-qPCR was used to measure the mRNA levels of Ajuba and YAP1 in the rat renal cortex.RESULTS:Biochemical indices revealed significantly ele-vated levels of blood glucose,serum creatinine,triglycerides,total cholesterol,and 24-hour urinary protein in the DM group compared to the NC group(P<0.05).In the DM+rAAV-BMP7 group,the levels of serum creatinine,24-hour uri-nary protein,triglycerides,and total cholesterol were lower than those in the DM group(P<0.05).Pathological staining demonstrated that the renal interstitium of the DM group exhibited inflammatory cell infiltration,fibrous tissue,collagen fi-ber deposition,disordered renal tubule arrangement,atrophy,and vacuolar degeneration,which were ameliorated in the DM+rAAV-BMP7 group.Immunohistochemistry revealed that Ajuba and YAP1 were mainly expressed in the cytoplasm and nucleus,with high expression in the cytoplasm of the DM group,which was significantly decreased in the DM+rAAV-BMP7 group.Western blot results indicated that the protein levels of FN,Col-Ⅲ,Ajuba,and YAP1 were up-regulated in the DM and the HG groups(P<0.05),but significantly down-regulated in the DM+rAAV-BMP7 group(P<0.05).RT-qP-CR results demonstrated that the mRNA levels of Ajuba and YAP1 were higher in the DM group and significantly lower in the DM+rAAV-BMP7 group(P<0.05).CONCLUSION:The overexpression of BMP7 can ameliorate renal fibrosis in rats with DKD.This effect is likely mediated by the down-regulation of Ajuba,reduction of YAP1 expression,and subse-quent inhibition of ECM deposition.

Objective To evaluate the short-term efficacy and safety of percutaneous liver puncture for local management of portal vein thrombosis(PVT).Methods Variations in thrombus,blood flow,and laboratory examination results were observed before and after percutaneous liver puncture in 197 patients with PVT,and the occurrence of comorbidities was recorded and followed up for one year after treatment.Results After treatment,the thrombus in the main portal vein vessels almostly disappeared in 119 patients(60.41％)with PVT,the thrombus had a significant reduction in 57 patients(28.93％),and the thrombus had a smaller change or an increase in 21 patients(10.66％);146 patients(74.11％)had smooth blood flow in the main portal vein vessels,29 patients(14.72％)showed significant improvement in blood flow,and 22 patients(11.17％)showed no significant improvement or worsening of blockage.The mean portal venous pressure was significantly lower than that before treatment(P＜0.001);thrombin time,activated partial thromboplastin time,and prothrombin time were prolonged compared to those before thrombolysis(P＜0.001),and fibrinogen were reduced compared to those before thrombolysis(P＜0.001).A total of 35 patients(17.77％)occured comorbidities during treatment.One year after treatment,196 patients(99.49％)with PVT survived,of which thrombus essentially disappeared in 141(71.94％),thrombus stabilized(or decreased)in 42(21.43％),and thrombus increased in 13(6.63％).Conclusion percutaneous liver puncture for local management of PVT is effective and reliable in the short-term and requires standardized management of the entire process.

The study presents a method for the personalized biomechanical modeling of the human head and validates the generated model.Based on the TUST 50th percentile head biomechanical model,the method utilizes head CT data of the target model,and employs three-dimensional point cloud registration and free-form deformation techniques to rapidly develop a personalized head finite element model with detailed brain tissue structures.By reconstructing classic cadaver tests,it is found that the personalized head biomechanical model created by the proposed method shows a good consistency with the results of cadaver tests in kinematic and biomechanical responses.Furthermore,no significant differences are observed when compared with the head biomechanical model developed using reverse engineering method,thus verifying the effectiveness of the developed model.Consequently,the proposed method can be used to quickly construct personalized head biomechanical models with detailed anatomical structures,providing a fundamental computational analysis tool for researches in injury biomechanics,clinical medicine,and forensic identification.
