ObjectiveTo explore the microbiological characteristics of Staphylococcus epidermidis with hemolytic phenotype （SEHP）. MethodsHemolytic phenotype was detected using the three-point inoculation method， involving a total of 5 strains of SEHP and 5 strains of Staphylococcus epidermidis with non-hemolytic phenotype （SENHP） . Bacterial species were identified using the Microflex LT MALDI-TOF mass spectrometer， and a phylogenetic tree was constructed through 16S rRNA sequence alignment. Growth curves were monitored through the microcultivation assay. Biofilm formation ability was assessed by microplate crystal violet staining. Red blood cell toxicity was detected using the microplate method. Antimicrobial susceptibility testing of SEHP and SENHP against commonly used antibiotics was performed using a VITEK 2 GP639 test kit. Antagonistic effects of SEHP and SENHP against Staphylococcus aureus and Corynebacterium striatum were evaluated by the Oxford cup inhibition assay. ResultsCompared with SENHP， SEHP exhibited a marked decrease in growth rate during the late logarithmic phase， accompanied by significant hemolytic toxicity. Additionally， it showed lower resistance rates to levofloxacin and moxifloxacin， and could antagonize Staphylococcus aureus and Corynebacterium striatum. ConclusionThe microbiological characteristics of SEHP differ from those of SENHP in that SEHP demonstrates antagonistic effects against S. aureus and C. striatum.

Objective To construct a conceptual framework and methodology for developing disability eligibility/standard using the bio-psycho-social model of disability,and classification theory and methods of the International Classification of Functioning,Disability and Health(ICF).Methods Based on the ICF's bio-psycho-social model,and aliged with the United Nations Convention on the Rights of Persons with Disabilities and the World Health Organization technical documents in the fields of disability statis-tics and services,this study explored the systematic implementation of ICF to construct a conceptual framework and methodology for disability eligibility/standards,including core concepts and terminology of functioning and disability,methods and system of classification and grading,coding system,standardization of disability survey questionnaires and protocols,and assessment/evaluation tools,as well as standard system of disability data.Results The establishment of disability standards should be based on specific application contexts and functions.Stan-dards for surveys and statistics emphasized data collection and analysis,applied to the design of survey question-naires and methodologies.Standards for service eligibility focused on determining service qualification through structured assessments/evaluation of functioning and disability.Comprehensive standards served both purposes.A well-rounded disability standard integrated a clear theoretical framework,scientific classification,grading and coding systems,and standardized disability reporting and evaluation/assessment methods/tools.The conceptual framework and methodological system for disability standards based on ICF comprised five core aspects:a core conceptual and terminological system for disability;disability classification and grading methods and systems;a scientifically structured classification,grading,and coding system;standardized disability reporting and assess-ment/evaluation methods and procedures;and standardized disability data systems.Applying ICF in practice in-volved systematically integrating the theoretical framework into the development of disability classification and grading systems,constructing coding systems using ICF,implementing standardized disability reporting and as-sessment/evaluation tools derived from the ICF,designing and standardizing disability survey instruments,ques-tionnaires/protocols,and assessment/evaluation tools and protocols,and establishing ICF-based disability data standards.Conclusion ICF provides a robust conceptual framework and methodology for the development of disability eligibility/standards.The bio-psycho-social model,conceptual framework and methodological approaches of classification,grading and coding of functioning and disability,and ICF-based standardized survey and assessment/evaluation tools,enable the establishment of core disability concepts and terminology,disability classification and grading systems,disability coding systems,disability survey questionnaires and protocols and assessment/evaluation tools and programs,and disability data standards.The systematic application of the ICF framework and method-ology enhances the scientific rigor,inclusivity and applicability of disability eligibility/standards.

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.

ObjectiveTo investigate the mechanism of action of Bushen Huoxue prescription （BSHXP） in regulating premature ovarian failure in rats through the PTEN-induced kinase 1 （PINK1）/Parkinson's protein （Parkin） signaling pathway-mediated mitophagy. MethodsA total of 48 rats were randomly divided into a blank group consisting of eight rats， while the remaining 40 rats underwent modeling. The modeling group was intraperitoneally injected with 4 mg·kg^-1 cisplatin solution， followed by a second injection one week later， for a total of two injections. The estrous cycle was observed through vaginal smears for 14 consecutive days to determine whether the modeling was successful. The successfully modeled rats were randomly divided into a model group， groups receiving low， medium， and high doses of BSHXP at 9.72， 19.44， and 38.88 g·kg^-1·d^-1 （BSHXP-L， BSHXP-M， and BSHXP-H groups）， and a positive control group treated with estradiol valerate （0.09 mg·kg^-1·d^-1）， for 21 consecutive days. The body weight of the rats was measured weekly. After the final administration， rats were anesthetized， and their blood and ovaries were collected. The ovarian weight was measured. Enzyme-linked immunosorbent assay （ELISA） was used to detect serum levels of anti-Müllerian hormone （AMH）， follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， and estradiol （E₂）. Assay kits were used to measure the levels of superoxide dismutase （SOD） and malondialdehyde （MDA） in the rat serum. Hematoxylin-eosin （HE） staining was used to observe the morphological changes in the ovaries. Immunohistochemistry （IHC） was performed to detect microtubule autophagy-related protein 1 light chain 3B（LC3B） protein expression in ovarian tissue， and electron microscopy was employed to examine the mitochondrial and autophagosome changes in the rat ovaries. Western blot was used to detect the protein expression of PINK1， Parkin， LC3B， and p62. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of PINK1， Parkin， LC3B， and p62 in ovarian tissue. ResultsCompared with the blank group， the model group showed significant reductions in body weight， weight gain， and ovarian weight （P<0.01）， along with decreased serum AMH and E₂ levels （P<0.01）， while FSH and LH levels were increased （P<0.01）. Serum MDA levels were significantly increased （P<0.01）， and SOD levels were significantly reduced （P<0.01）. The ovarian tissue structure was disordered， and the zona pellucida was wrinkled into an irregular acidophilic annular object， accompanied by an increased number of closed follicles. Electron microscopy showed mitochondrial swelling， unclear structure， and no obvious autophagosomes and autolysosome structures. The proteins and mRNA expression levels of PINK1， Parkin， LC3B， and p62 in the ovarian tissue were significantly reduced （P<0.01）. Compared with the model group， all treatment groups showed varying degrees of increases in body weight and ovarian weight （P<0.05， P<0.01）. Except for the BSHXP-L group， all treatment groups showed increased body weight gain （P<0.01）. All treatment groups showed significantly increased serum AMH and decreased FSH levels （P<0.01）. Except for the BSHXP group， all treatment groups showed varying degrees of increase and decrease in serum E₂ and LH levels （P<0.05， P<0.01）. All treatment groups showed reduced serum MDA levels （P<0.01）， while the BSHXP-M， BSHXP-H， and the positive control groups demonstrated improved serum SOD levels （P<0.05， P<0.01）. All treatment groups showed an increased number of follicles at all stages， visible mature follicles， and a decreased number of closed follicles. Electron microscopy showed relieved mitochondrial swelling， morphology close to normal， clear structure， and visible formation of autolysosomes in all treatment groups. Additionally， the protein and mRNA expression levels of PINK1， Parkin， LC3B， and p62 in ovarian tissue were significantly increased （P<0.05， P<0.01）. ConclusionBSHXP may improve ovarian function in rats with premature ovarian failure by regulating the PINK1/Parkin signaling pathway， activating mitochondrial autophagy， and reducing oxidative damage.
