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 explore the mechanisms of action of Huanglian Jiedu decoction combined with Xijiao Dihuang decoction (HLJDT-XJDH) in regulating fibroblasts in the treatment of psoriasis. Methods:A mouse model of psoriasis was established by topical application of imiquimod 5% cream on the shaved back; HLJDT-XJDH at different doses of 7.7 and 30.6 g/kg was administered via gavage for intervention, and methotrexate (2 mg/kg) served as a positive control; after 7 days, the severity of skin lesions was assessed using the psoriasis area and severity index (PASI), while histopathological changes of skin tissues were evaluated using hematoxylin-eosin (HE) staining and Baker scoring. For in vitro experiments, fibroblasts were divided into a control group, a model group, a low-dose (5% drug-containing serum) intervention group, and a high-dose (20% drug-containing serum) intervention group; cells in the control group were cultured with 20% normal rat serum for 24 hours; in the model group, cells cultured with 20% normal rat serum were stimulated with 5 ng/ml tumor necrosis factor (TNF) -α and 50 ng/ml interleukin (IL) -17A for 24 hours to mimic fibroblasts during the occurrence of psoriasis; cells in the low- and high-dose intervention groups received the same stimulation as the model group, and were cultured for 24 hours with 5% and 20% HLJDT-XJDH-containing serum, respectively, but not with the 20% normal rat serum. After the above treatment, these cells were co-cultured with keratinocytes (HaCaT cells) using a Transwell system. In addition, on the basis of the control group, fibroblasts were divided into the model group, 20% drug-containing serum intervention group, and 20% drug-containing serum intervention + OE-SFRP2 group; TNF-α and IL-17A were used to stimulate the cells to simulate the psoriatic state; the treatment in the 20% drug-containing serum intervention group was carried out as previously described; in the 20% drug-containing serum intervention + OE-SFRP2 group, cells were transfected with the vector for 48 hours to establish an overexpression model, followed by culture with 20% drug-containing serum for 24 hours, without co-culture with HaCaT cells.. Cell counting kit-8 (CCK-8) assay was performed to assess cell viability, flow cytometry to measure apoptosis rates, enzyme-linked immunosorbent assay (ELISA) to detect levels of inflammatory cytokines (TNF-α, IL-1β, IL-6) as well as chemokine ligand (CXCL) 1 and CXCL12 in mouse serum or cell culture supernatant, qPCR to determine the mRNA expression of inflammatory cytokines, chemokines, cell cycle- and proliferation-related factors, as well as SFRP2 in mouse skin tissues or cells, and Western blot analysis to determine the protein expression of SFRP2, Wnt3a, and β-catenin in fibroblasts. One-way analysis of variance was employed for intergroup comparisons, and post-hoc analysis was conducted using Tukey's test. Results:In vivo mouse experiments showed that compared with the normal control group, the model group exhibited typical psoriatic characteristics in skin morphology, including significant inflammatory infiltration in skin tissues and marked epidermal thickening; compared with the normal control group, the serum levels of TNF-α (531.16 ± 28.27 pg/ml vs. 239.58 ± 10.39 pg/ml), IL-1β (111.40 ± 5.16 pg/ml vs. 80.35 ± 3.87 pg/ml), and IL-6 (109.17 ± 4.84 pg/ml vs. 71.73 ± 2.04 pg/ml) significantly increased in the model group, along with their mRNA expression levels in mouse skin tissues (all P < 0.001) ; compared with the model group, the treatment group showed alleviated psoriatic manifestations, and significant reductions in the levels of inflammatory factors TNF-α (low-dose, high-dose, and positive control groups: 420.80 ± 29.30 pg/ml, 322.33 ± 9.40 pg/ml, 322.97 ± 12.16 pg/ml, respectively), IL-1β (98.69 ± 4.49 pg/ml, 89.02 ± 1.56 pg/ml, 88.88 ± 2.08 pg/ml, respectively), and IL-6 (94.07 ± 3.76 pg/ml, 80.54 ± 3.30 pg/ml, 83.21 ± 3.18 pg/ml, respectively), as well as in their mRNA expression levels (all P < 0.001). In in vitro fibroblast experiments, compared with the control group, the model group exhibited a significant elevation in the supernatant levels of IL-1β (126.42 ± 3.56 pg/ml vs. 34.81 ± 0.44 pg/ml), IL-6 (459.44 ± 9.35 pg/ml vs. 115.51 ± 7.26 pg/ml), CXCL1 (2 434.88 ± 127.63 pg/ml vs. 762.85 ± 30.60 pg/ml) and CXCL12 (3 542.14 ± 35.86 pg/ml vs. 2 095.86 ± 45.12 pg/ml), the expression levels of their mRNAs (all P < 0.001), as well as the protein expression levels of SFRP2, Wnt3a, and β-catenin; after intervention with HLJDT-XJDH-containing serum, all the above indices significantly decreased (all P < 0.001). However, when 20% drug-containing serum intervention was administered simultaneously, the expression of inflammatory factors and chemokines in fibroblasts was significantly higher in the SFRP2 overexpression group than in the non-overexpression group (all P < 0.01). When fibroblasts were co-cultured with HaCaT cells, the model group showed significantly increased cell viability but a decreased apoptosis rate of HaCaT cells compared with the control group, while the low- and high-dose intervention groups showed significantly decreased cell viability but increased apoptosis rates of HaCaT cells compared with the model group (all P < 0.05) . Conclusion:HLJDT-XJDH may exert therapeutic effects in psoriasis by downregulating the SFRP2/Wnt/β-catenin signaling pathway, thereby inhibiting fibroblast activation and inflammatory process, which subsequently suppresses the proliferation of keratinocytes and the activation of inflammatory cells.

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.

Objective : To investigate the causes of false negative results in the detection of Streptococcus agalactiae using fluorescent quantitative PCR(qPCR) targeting the CAMP factor gene(cfb),and to perform a comprehensive analysis of the associated molecular mechanisms. Methods: A total of 76 vaginal secretion samples were evaluated using both qPCR based on cfb gene and bacterial culture methods. Four suspicious strains exhibiting negative qPCR results but positive culture findings were identified using matrix-assisted laser desorption ionization time-of-flight mass spectrometry(MALDI-TOF MS),latex agglutination antigen detection,and the CAMP test. Whole genome analysis was conducted utilizing the MGI DNBSEQ-T7 and Nanopore-PromethION 48 sequencing platforms. Phylogenetic and circular evolutionary trees were constructed using the 16S rRNA gene for strain verification. Multilocus sequence typing(MLST) was conducted,and cfb sequences were aligned and analyzed based on spliced sequences and original data. Specific primers targeting the cfb gene were designed for full-length amplification,followed by verification through agarose gel electrophoresis. Results: The four strains identified as suspicious were classified as S. agalactiae through MALDI-TOF MS,antigen detection,and 16S rRNA gene analysis,with MLST typing indicating ST-862. Phenotypic analysis revealed a negative CAMP test. Whole genome sequence alignment failed to detect the cfb gene or any homologous sequences,and molecular testing confirmed the absence of cfb gene PCR amplification products,thereby confirming its complete deletion. Conclusion This deletion is identified as the molecular mechanism responsible for the false negative qPCR detection of S. agalactiae when targeting this specific gene.It is recommended that the qPCR detection targeting a single cfb gene has limitation,and this may impact clinical diagnosis and treatment decisions. This limitation warrants carefulconsideration.

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.

ObjectiveBased on transcriptomics， to explore the mechanism of Hei Xiaoyaosan regulating the phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway to improve the learning and memory ability of insomnia rats with liver depression syndrome. MethodsSixty 8-week-old male SD rats were randomly divided into the blank group， model group， eszopiclone group （0.09 mg·kg^-1）， and low， medium， and high dose groups of Hei Xiaoyaosan （3.82， 7.65， 15.30 g·kg^-1）， with ten rats in each group. Except for the blank group， the other groups were induced insomnia rat model with liver depression by chronic restraint， tail clamping stimulation and intraperitoneal injection of p-chlorophenylalanine （PCPA）. Each treatment group received intragastric administration according to the specified dosage， once a day for 14 consecutive days. The pentobarbital sodium cooperative sleep test， open field test， and Morris water maze test were used to test the sleep quality， depressive-like behavior， and learning and memory abilities of rats. Additionally， enzyme-linked immunosorbent assay （ELISA） was used to detect the contents of 5-hydroxytryptamine （5-HT）， γ-aminobutyric acid （GABA）， brain-derived neurotrophic factor （BDNF）， glial cell line-derived neurotrophic factor （GDNF） and nitric oxide （NO） in hippocampus. Hematoxylin-eosin （HE） staining was performed to observe pathological changes of the hippocampal tissue， while terminal deoxynucleotidyl transferase deoxyuridine triphosphate （dUTP） nick end labeling （TUNEL） was used to evaluate apoptosis of hippocampal neurons. Transcriptomic sequencing technology was employed to identify differentially expressed genes in hippocampus between the model group and the blank group， as well as between the medium-dose group of Hei Xiaoyaosan and the model group. Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analysis were performed on the intersecting genes. Subsequently， the enriched key genes and signaling pathways were analyzed and verified. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was utilized to assess the mRNA expression levels of phosphatase and tensin homolog （PTEN）， B-cell lymphoma-2 （Bcl-2）-like protein 11 （BCL2L11）， and mitogen-activated protein kinase 1 （MAPK1） in hippocampus， and Western blot was employed to evaluate the protein expressions of PI3K， phosphorylation （p）-PI3K， Akt， p-Akt， Bcl-2， Bcl-2-associated X protein （Bax）， and cleaved Caspase-3 in the same tissue. ResultsCompared with the blank group， the model group exhibited a reduction in body weight， an increase in sleep latency， and a decrease in sleep duration （P<0.01）. Additionally， rats showed obvious depression-like behavior， and their learning and memory abilities decreased. Furthermore， the contents of 5-HT， GABA， NO， BDNF and GDNF in hippocampus decreased （P<0.01）. Histological examination revealed a disorganized cell arrangement in the CA1 region of the hippocampus， characterized by irregular cell shapes， a reduced cell count， deeply stained and pyknotic nuclei， increased vacuolar degeneration， and an elevated apoptosis rate （P<0.01）. Compared with the model group， the body weight of the high and medium dose groups of Hei Xiaoyaosan increased， the sleep latency shortened and the sleep time prolonged （P<0.05， P<0.01）. Additionally， depression-like behavior and learning and memory abilities of rats were significantly improved， the levels of 5-HT， GABA， NO， BDNF and GDNF in the hippocampus increased （P<0.05， P<0.01）. These interventions also ameliorated pathological damage in the hippocampal CA1 area and reduced the apoptosis of hippocampal neurons （P<0.01）. Transcriptomic sequencing results indicated that Hei Xiaoyaosan might exert a therapeutic effect by regulating PI3K/Akt pathway through key mRNAs such as PTEN， BCL2L11， and MAPK1. The roles of these key mRNAs and proteins within PI3K/Akt pathway were further validated. In comparison to the blank group， the expression levels of PTEN， BCL2L11 and MAPK1 mRNA in the hippocampus of rats in the model group were increased （P<0.01）， while the protein expression levels of p-PI3K， p-Akt and Bcl-2 were decreased （P<0.01）， and the protein expression levels of PTEN， Bax and cleaved Caspase-3 were increased （P<0.01）. Compared with the model group， the high-dose and medium-dose groups of Hei Xiaoyaosan could down-regulate the expressions of PTEN， BCL2L11 and MAPK1 mRNAs （P<0.01）， up-regulate the expressions of p-PI3K， p-Akt and Bcl-2 proteins （P<0.01）， and down-regulate the protein expressions of PTEN， Bax and cleaved Caspase-3 （P<0.05， P<0.01）. ConclusionHei Xiaoyaosan may regulate PI3K/Akt signaling pathway by down-regulating expressions of key genes such as PTEN， BCL2L11 and MAPK1， and thus improve the learning and memory abilities of insomnia rats with liver depression syndrome.
