Objective To investigate the effect of bone metabolic markers on sarcopenia in elderly patients with type 2 diabetes mellitus (T2DM). Methods A total of 412 patients with T2DM in the department of endocrinology of Nanjing Central Hospital from May 2020 to June 2025 were selected as the research subjects. According to Asian Working Group for Sarcopenia (AWGS) in 2019, these patients were evaluated for skeletal muscle mass index (ASMI), muscle strength, and muscle function, and were divided into a sarcopenia group (84 cases) and a non-sarcopenia group (328 cases). The glucolipid metabolic indexes were detected in both groups of patients, and the bone metabolic markers were evaluated, including procollagen type 1 N-terminal peptide (P1NP), beta-C-terminal telopeptide of type 1 collagen (β-CTX), and 25-hydroxy vitamin D [25-(OH)D]. The factors influencing the occurrence of sarcopenia in T2DM patients were analyzed by logistic regression analysis, and the diagnostic values of bone metabolic markers on sarcopenia in patients with T2DM were assessed by ROC curve. Results The levels of P1NP and 25-(OH)D were lower, while β-CTX level was higher in the sarcopenia group compared to the non-sarcopenia group, with statistical differences (P<0.05). After logistic correlation analysis, it was found that P1NP, β-CTX and 25-(OH)D were all influencing factors for the occurrence of sarcopenia in T2DM patients. ROC curve analysis suggested that combined detection of PINP, β-CTX, and 25-(OH)D had higher diagnostic value, with an area under the curve up to 0.805. Conclusion The abnormal expression of bone metabolic markers is associated with the increased risk of sarcopenia in patients with T2DM. The detection of serum bone metabolic markers expression level is of certain significance for the assessment of diabetes-related sarcopenia.

ObjectiveTo systematically assess the public health governance capacity in Zhejiang Province, to conduct an in-depth analysis of its strengths and weaknesses, so as to provide scientific basis and strategic recommendations for further enhancement. MethodsA systematic collection of policy documents, public information reports, and research literature related to public health governance capacity in Zhejiang Province from 2002 to 2023 was conducted (encompassing a total of 1 263 policy documents, 138 pieces of information reports and 631 research articles). Based on the evaluation criteria suitable for public health systems previously developed by the research team, the basic status and magnitude of change in public health governance capacity in Zhejiang Province was evaluated. Additionally, normative gap analyses were employed to identify the strengths and weaknesses. ResultsZhejiang Province ranked 4th nationwide in terms of public health governance capacity with a score of 733.4 points (1 000.0-point maximum). The province has effectively implemented the principle of health first (scoring 698.5 points in the assessment of health-first strategy implementation) and attached sufficient importance to health-related goals (scoring 658.2 points in the scientific rationality of goal setting). However, the implementation of inter-departmental coordination and incentive mechanisms only scored 178.7 points, the feasibility of management and monitoring mechanisms scored even lower at only 144.0 points, and the coverage of incentive mechanisms scored 286.0 points. ConclusionZhejiang Province has effectively implemented its health first strategy and attached great importance to health targets, but still needs to strengthen cross-departmental coordination mechanisms and health-oriented incentives.

ObjectiveTo develop a community-family management model for older adults with mild cognitive impairment (MCI) and to formulate detailed application specifications, and to fully leverage the initiative of communities and families under limited resource conditions, for achieving community-based early detection and early intervention for older adults with MCI. MethodsA systematic literature review was conducted to identify pertinent publications. Corpus-based research methodologies were employed to extract, refine, integrate and synthesize management elements, thereby establishing the specific content and service processes for each stage of the management model. Utilizing the 5W2H analytical framework, essential elements such as management stakeholders, target populations, content and methods for each stage were delineated. The model and its application guidelines were finalized through expert consultation and demonstration. ResultsAn expert evaluation of the management model yielded mean scores of 4.84, 4.32 and 4.84 for acceptability, feasibility and systematicity, respectively. By integrating the identified core elements with expert ratings and feedback, the final iteration of the community-family management model for older adults with MCI was formulated. This model comprised of five stages: screening and identification, comprehensive assessment, intervention planning, monitoring and referral pathways to ensure implementation, and enhanced support for communities, family members and caregivers. Additionally, it included 18 specific application guidelines. ConclusionThe proposed management model may theoretically help delay cognitive decline, improve cognitive function and potentially promote reversal from MCI to normal cognition. It may also enhance the awareness and coping capacity of older adults and their families, strengthen community healthcare professionals' ability to early identify and manage MCI.

BackgroundIndividuals with chronic multimorbidity exhibit a high prevalence of sleep disturbances， which impair their physical and psychological well-being and impede chronic disease management. Although sleep quality is closely influencing with psychological functioning， empirical evidence regarding the longitudinal trajectories of sleep quality and their influencing factors in this population remains insufficient. ObjectiveTo investigate the longitudinal trajectories of sleep quality and associated factors among patients with chronic multimorbidity from hospitalization through 6 months post-discharge， aiming to facilitate the early identification of high-risk individuals and the development of personalized sleep interventions. MethodsA total of 228 inpatients with chronic multimorbidity， primarily with cardiovascular and metabolic chronic conditions， were enrolled via random sampling at The Third People's Hospital of Fuyang from January 2023 to September 2024. Baseline assessments were conducted during hospitalization using the general socio-demographic questionnaire， the Sleep Dysfunction Rating Scale （SDRS）， the Ruminative Response Scale （RRS）， and the Hospital Anxiety and Depression Scale （HADS）. Sleep quality was further evaluated using the SDRS at 1-， 3-， and 6-month post-discharge. Latent class growth model was employed to delineate trajectories of sleep quality. Multivariate logistic regression analysis was subsequently performed to identify influencing factors of sleep quality. ResultsA total of 201 patients with chronic diseases were included.Based on four predefined assessment time points （baseline， 1 month， 3 months， 6 months post-discharge）， the latent class growth model identified three distinct trajectories of sleep quality： persistent high sleep disturbance （n=72， 35.82%）， moderate sleep disturbance-progression （n=73， 36.32%）， and low sleep disturbance （n=56， 27.86%）. Multivariate logistic regression analysis revealed that， compared with the low sleep disturbance group， multiple factors increased the odds of membership in the persistent high sleep disturbance group： per capita monthly household income of <3 000 yuan （β=13.131， P<0.01） or 3 000–5 000 yuan （β=5.913， P<0.05）， aged 45–65 years （β=9.536， P<0.05）， presence of 3 （β=7.792， P<0.05） or >3 comorbid chronic conditions （β=6.626， P<0.05）， as well as higher RRS （β=0.334， P<0.01） and HADS score （β=1.628， P<0.01）. Additionally， patients aged 45–65 years （β=2.777， P<0.05）， with 3 （β=3.802， P<0.01） or >3 comorbid chronic conditions （β=2.463， P<0.01）， and with higher RRS （β=0.111， P<0.01） and HDAS scores （β=0.350， P<0.05） also demonstrated significantly increased odds of belonging to the moderate sleep disturbance–progression group. ConclusionThere is significant population heterogeneity in sleep quality trajectories among patients with chronic multimorbidity， with age， per capita household monthly income， number of comorbidities， rumination， and anxiety/depression symptoms being identify as the primary influencing factors.

Objective To analyze the correlation of preoperative collagen lectin-11(CL-11),urinary nitrite,and urinary heparin-binding protein(U-HBP)with postoperative urinary sepsis(US)in patients with kidney stones,and to explore their predictive value and warning significance for postoperative US.Methods A total of 190 patients with kidney stones who underwent minimally invasive percutaneous nephrolithotomy at the Second Affiliated Hospital of Kunming Medical University from September 2021 to June 2023 were selected.According to whether they developed US within 7 days after surgery,they were divided into the US group(n=30)and the non-US group(n=160).Baseline data and preoperative levels CL-11,urinary nitrite and U-HBP were compared between the two groups.The correlation between preoperative CL-11,urinary nitrite,U-HBP and postoperative US was analyzed.The predictive efficacy of preoperative CL-11,urinary nitrite,and U-HBP for postoperative US was evaluated.Results The positive rates of CL-11,urinary nitrite,and U-HBP in the US group were(313.68±38.73)ng/mL,46.67%and(157.82±41.61)ng/mL,respectively,which were higher than those in the non-US group at(234.00±41.25)ng/mL,12.50%,and(128.59±36.38)ng/mL(P<0.05).Logistic regression analysis indicated that preoperative CL-11,urinary nitrite,and U-HBP were influencing factors for the occurrence of US.The area under the curve(AUC)for predicting postoperative US was 0.797 for CL-11,0.624 for urinary nitrite,and 0.826 for U-HBP,while the combined AUC for predicting postoperative US was 0.923,with a sensitivity of 90.00%and specificity of 88.75%.Conclusion Patients with postoperative US following kidney stone surgery exhibited elevated levels of urinary nitrite,CL-11,and U-HBP,which were positively correlated with the occurrence of postoperative US.These markers have certain predictive value for postoperative US,and their combined detection offers superior predictive efficacy,potentially serving as warning biomarkers for postoperative US,thereby providing a reference for clinical prevention and control measures.

Creutzfeldt-Jakob disease(CJD)is a rapidly progressive and fatal neurodegenerative disorder caused by prions,with certain infectivity and iatrogenic transmission risks.With the rapid progress and application of new dia-gnostic biomarkers and detection methods,as well as the construction and improvement of surveillance and reporting systems,the detection of CJD in patients domestically and internationally has shown an increasing trend year by year.Due to its long incubation period and heterogeneity of early symptoms,early identification and diagnosis of the disease is difficult,increasing the risk of transmission within medical institutions.Currently,there is a lack of con-sensus on the infection prevention and control of CJD.In order to timely identify and diagnose CJD as well as effec-tively block its transmission in medical institutions,this consensus summarizes 15 clinical concerns and formulates 24 specific recommendations based on the latest domestic and international research findings and clinical evidence,as well as combines with clinical practice,aiming to standardize healthcare-associated infection prevention and control measures for CJD and reduce its transmission risk in medical institutions.

Purpose To investigate the clinicopathological features and diagnosis of breast epithelial-myoepithelial tumors.Methods Collect 10 cases of breast epithelial-myoepithelial tumors.Clinical features,histopathologic fea-tures,immunophenotype,and molecular characteristics were analyzed.Results All patients were female,aged 27-49 years,and the maximum diameter of the mass was 1.5 to 6.0 cm.Among them,8 cases were diagnosed as adeno-myoepithelioma(AME)of the breast,1 case as atypical AME,and 1 case as malignant adenomyoepithelioma(AME-M).All ten patients were alive with no evidence of disease or metastasis,with follow-up periods ranging from 4 to 64 months.All epithelial-myoepithelial tumors consisted of proliferative epithelial and myoepithelial cells,with myoepithe-lial hyperplasia being the predominant component.In the atypical AME case,myoepithelial cells exhibited mild to moderate atypia,with mitotic figures observed occasionally(3/10 HPF).AME-M was composed of solid and cystic ar-eas.In the solid area,myoepithelial cells exhibited moderate to severe atypia with a high mitotic rate(6-8/10 HPF).Additionally,necrosis and areas of squamous cell carcinoma were present,leading to a diagnosis of epithelial-myoepithelial carcinoma.Papillary squamous cell carcinoma was found in cystic area and it involved the adjacent lob-ules.The peripheral breast tissue contained focal ductal carcinoma in situ.The luminal epithelial cells showed expres-sion of CK8/18 and CK7.The myoepithelial cells showed expression of p63,CD10,and SMA.The Ki67 index was less than 10％in AME,40％in atypical AME.In the AME-M,it was 80％in the epithelial-myoepithelial carcinoma component,and 70％in the papillary squamous cell carcinoma component.Sanger sequencing of 6 cases AME and 1 case atypical AME revealed no hotspot mutations in HRAS or PIK3CA.In one case of AME-M,pyrosequencing indica-ted no hotspot mutations of AKT1,KRAS,HRAS,and PIK3 CA in the components of epithelial-myoepithelial carcino-ma and papillary squamous cell carcinoma while one KRAS(c.183A＞C/T,p.Q61H)mutation was present in the peripheral ductal carcinoma in situ.Molecular genetic analysis on 22 short tandem repeat loci showed an identical pat-tern including LOH at D19S433 in both components of AME-M and squamous cell carcinoma.Conclusion AME is an rare tumor with a heterogeneous morphology.The biphasic proliferation of epithelial and myoepithelial components is the key to correct diagnosis.Molecular genetic analysis suggested AME-M and squamous cell carcinoma were clonally independent from the peripheral ductal carcinoma in situ.

Objective:To explore the effectiveness of find-organize-clarify-understand- select-plan-do-check-act (FOCUS-PDCA) cycle management in improving the accuracy of Nutritional Risk Screening 2002 (NRS 2002) scoring in inpatients.Methods:This study was a retrospective study. Data from a continuous quality improvement project, namely Improving the Accuracy of Nutritional Risk Screening for Inpatients from People's Hospital of Longhua in 2021 were selected. The NRS 2002 scores of newly admitted patients from 8 departments with relatively high nutritional risk (departments of gstroenterology, neurology, nephrology, respiratory medicine, oncology and hematology, neurosurgery, gastrointestinal surgery, and critical care medicine) from April 10, 2021 to April 29, 2021 (before intervention) were collected. The NRS 2002 scores were evaluated by a multidisciplinary nutrition support team in terms of accuracy and error types. Possible issues in the process of nutritional screening were analyzed and mitigated using the FOCUS-PDCA cycle management method. The NRS 2002 scores from July 18, 2021 to August 8, 2021 (after intervention) were collected in real time to summary the data on accuracy and error types and to evaluate the effect of FOCUS-PDCA.Results:The accuracy of NRS 2002 score in the 8 departments was increased from 52.97% (294/555) to 81.13% (473/583) after intervention, and the difference was statistically significant ( χ2=102.606, P<0.001). The accuracy of nutritional status impairment score was 64.14% before intervention, compared with 90.57% after intervention ( χ2=114.484, P<0.001). The accuracy of disease severity score was 78.56%, compared with 89.54% after intervention( χ2=25.736, P<0.001). The false-negative rate was 68.02% before intervention and 31.87% after intervention, and the difference was statistically significant ( χ2=31.501, P<0.001). Conclusion:FOCUS-PDCA can improve the accuracy of NRS 2002 scoring in inpatients, reduce the risk of failing to identify patients at nutritional risk, and contribute to further nutritional diagnosis and treatment.

AIM:This study aims to investigate the therapeutic effects of Xiaozhen Fang(XZF)on epidermal growth factor receptor(EGFR)inhibitor,erlotinib-induced skin toxicity in mice,with a focus on the underlying functional mechanisms.METHODS:A mouse model of skin toxicity was established and divided into three groups(n=5 per group):blank,erlotinib(150 mg/kg),and erlotinib(150 mg/kg)combined with XZF(45 g/kg)groups.Skin toxicity se-verity and body weight were evaluated.Western blot was performed to detect protein levels of gasdermin D(GSDMD),caspase-1,and interleukin-1β(IL-1β)in skin tissue.Immunofluorescence was employed to analyze gasdermin E,IL-1β,caspase-1,and nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3)expression in skin tissue.In vitro,HacaT cells were cultured and treated with erlotinib followed by different concentrations of XZF-containing se-rum.Cell viability was assessed by MTT assay.Cell ultrastructure was observed by transmission electron microscopy,and p53-binding protein 1(53BP1)expression was analyzed by immunofluorescence staining.RESULTS:The XZF signifi-cantly alleviated erlotinib-induced skin toxicity in mouse model,as evidenced by reduced rash incidence,alleviated limb swelling,and increased body weight(P<0.05).Expression of Gasdermins,IL-1β,caspase-1,and NLRP3 was distinctly down-regulated in dorsal skin tissue(P<0.05 or P<0.01).In vitro,XZF-containing serum markedly suppressed pyropto-sis in HacaT cells(P<0.01),preserved cell membrane integrity,and significantly reduced 53BP1 fluorescence intensity(P<0.01).CONCLUSION:The XZF mitigates EGFR inhibitor,erlotinib-induced skin toxicity in mice,potentially by regulating pyroptosis through the NLRP3/caspase-1/GSDMD signaling pathway.This mechanism exerts a cytoprotective ef-fect and alleviates erlotinib-induced skin toxicity.
