Neonatal diabetes mellitus （NDM） is a rare monogenic disorder primarily caused by insufficient insulin secretion resulting from mutations in the KCNJ11 and ABCC8 genes. Sulfonylureas， represented by glibenclamide， have become the standard therapy for this type of NDM by precisely closing the mutated ATP-sensitive potassium channels in pancreatic β cells， thereby restoring insulin secretion. Clinical studies confirm that sulfonylureas enable over 90% of patients to successfully transition from insulin to oral treatment， achieving long-term stable glycemic control and improving neurological outcomes to a certain extent. In terms of safety， severe hypoglycemia induced by sulfonylureas is relatively rare and gastrointestinal reactions are mild； moreover， sulfonylureas show good long-term tolerability， and have no adverse effects on child growth and development. In the future， by further refining the full-chain management pathway of “rapid genetic diagnosis-early intervention-specialized dosage forms-long-term follow-up”， the clinical application of sulfonylureas is expected to provide NDM patients with an optimized treatment regimen and maximize their health benefits.

ObjectiveTo construct a competency model for "dual-qualified" teachers in vocational undergraduate rehabilitation therapy programs based on the World Health Organization's rehabilitation competency framework (RCF) and relevant domestic and international standards, and explore the training pathways for rehabilitation therapy teachers in China. MethodsLiterature analysis and comparative research methods were employed to systematically review RCF, physiotherapist-education-framework-FINAL, the Minimum-Standards-for-the-Education-of-Occupational-Therapists, and the "dual-qualified" teacher standards in vocational education for China. Focusing on the characteristics of vocational undergraduate talent cultivation, it took the integration of the "educator-clinical rehabilitation therapist" dual roles as its starting point, combining rehabilitation industry competence with educator standards as its basic principle, and using RCF as its foundational dimension. It then integrated advanced competency dimensions required of vocational undergraduate teachers to form a dimensional framework. Following the systematic curriculum development concept of the work process, the core activities of each dimension were designed by combining, improving and expanding the concept integration method, and describing the ability characteristics in a graded and progressive manner, to construct a model. ResultsThis model was guided by the core concepts of three types of values ​​and four types of professional beliefs. Vertically, it encompassed 28 activities across eight competency dimensions, including teaching practice, rehabilitation practice, digital literacy, professionalism, learning and development, management and leadership, applied research, and social service. Horizontally, it encompassed 53 corresponding competency characteristics across three advanced levels (beginner, intermediate and advanced). ConclusionThis model, through its vertical dimension design and horizontal progressive development, clearly describes the advancement of vocational undergraduate rehabilitation therapy teachers from newly hired teachers to backbone teachers and professional leaders. It not only aligns with the general requirements of the national standards for "dual-qualified" teachers in higher vocational colleges in China, but also incorporates an international perspective on rehabilitation education and practice, and possesses the characteristics of vocational undergraduate education that integrates multiple abilities and roles. At the theoretical level, it provides core theoretical support for establishing standardized and internationalized "dual-qualified" teacher standards for vocational undergraduate rehabilitation therapy programs in China; at the practical level, it serves as an "action map" for teacher professional development, assessment and evaluation, providing a key reference for constructing a systematic high-end skilled rehabilitation talent training system.

Objective:To develop and validate a clinical warning model for severe pediatric community-acquired pneumonia (CAP) using electronic health records.Methods:A retrospective cohort study was conducted, analyzing clinical data of 15 750 children hospitalized for CAP at Wuhan Children′s Hospital between January 1, 2019, and December 31, 2023. Patient data were randomly split into training and testing sets at a 7∶3 ratio. Six supervised machine learning models were constructed in the training set, optimized using five-fold cross-validation, and evaluated in the testing set. Model performance was assessed using ROC-AUC, sensitivity, specificity, positive predictive value, negative predictive value, calibration curves, and clinical decision curve analysis at optimal thresholds. The best-performing model was selected, and SHapley Additive exPlanations (SHAP) were used to interpret feature importance. A program interface was developed based on the model results, enabling integration into clinical decision support systems for automated early warning.Results:A total of 15 750 participants, ranging in age from 28 days to 18 years, were included in the study. The median age was 2 years [interquartile range (IQR): 0-4 years], with 9 555 males (60.67%) and 6 195 females (39.33%). Among them, 2 211 (14.04%) developed severe pneumonia. In the prediction models, XGB outperformed other models with an ROC-AUC of 0.884 (95% CI: 0.870-0.898), sensitivity (0.803, 95% CI: 0.772-0.832), specificity (0.828, 95% CI: 0.816-0.839). Calibration analysis showed strong agreement between predicted and observed risks (Brier score: 0.081, 95% CI: 0.075-0.086). The analysis based on the SHAP method revealed that respiratory rate, heart rate, T-lymphocyte subsets, and red blood cell volume distribution width-SD are predictive factors for severe progression of community-acquired pneumonia (CAP) in children. Conclusion:An interpretable machine learning model was developed for the early detection and personalized treatment planning of severe CAP in children, providing valuable support to clinicians.

Objective To analyze the antiviral effect of molnupiravir against influenza virus in vitro and in vivo.Methods The antiviral ability of molnupiravir against influenza virus strain H1N1 PR8 was detected in vitro and in vivo.H uman non-small cell lung cancer cell line(A549 cells)was used as an in vitro model of PR8 infection.The antiviral effects of molnupiravir on virus replication,protein synthesis,and viral particle formation were analyzed using real-time fluorescence quantitative polymerase chain reaction(qRT-PCR),Western blot(WB)assay,and plaque assay.PR8 nose-dripping infected C57BL/6 female mice were used as an in vivo infection model.The antivi-ral ability of molnupiravir was evaluated by detecting viral load,pathological changes,and immunohistochemistry in the control group,administration group,inoculation group,and inoculation-administration group.Results In vitro test results showed that molnupiravir had no significant inhibitory effect on influenza virus replication,protein syn-thesis,and virus particle formation(all P＞0.05).In vivo test results showed that compared with mice infected with H1N1 alone,the viral load in the lung tissue of mice treated with molnupiravir declined significantly,and the extent of pathological changes was milder.Immunohistochemical detection showed a significant weakening in nuclear protein(NP)antigen signal,and the expression levels of interferon(IFN)-α,interleukin(IL)-4,and IL-6 in the lungs were lower(all P＜0.01).Conclusion As a precursor with antiviral activity,molnupiravir can not exert anti-viral activity in lung-derived cells cultured in vitro,but can be transformed into an active form in the host,which significantly decreases the ability of H1N1 influenza virus to proliferate in the lungs and thereby alleviates the da-mage of virus to lung tissue.

Optical coherence tomography angiography (OCTA) is a non-invasive imaging technique that displays fundus blood vessels.Choroidal capillary (CC) is the intraocular tissue with the highest blood perfusion, and its pathological changes are closely related to the occurrence and progression of many retinal and choroidal diseases.Binarization of OCTA-scanned CC images can obtain images with alternating light and dark areas.The dark area represents that the blood flow signal in this area is lower than the detectable lowest resolution, and is defined as choriocapillaris flow deficit (CC FD). Further calculation can obtain the percentage of CC FD, the number of CC FD, CC FD average area and other related quantitative indicators.CC FD-related quantitative indicators are objective and reliable to evaluate the CC structure and perfusion status, thus can be used to predict the progress and prognosis of chorioretinal diseases and provide important reference for the diagnosis, treatment and prognosis of various eye diseases such as age-related macular degeneration, central serous chorioretinopathy and myopia.However, CC FD can be affected by interfering factors like age, scanning range and blood pressure.Besides, there are still several limitations in processing CC images.Therefore, we need to understand and use it correctly.This review summarizes the measurements, influencing factors and application of CC FD-related quantitative indicators obtained by OCTA in different eye diseases and systemic diseases.

As one of the most common and severe complications of diabetic mellitus,diabetic foot ulcers(DFUs)can result in severe tissue damage and dysfunction.Macrophage polarization is an important immune reactions,and the balance of macrophage polarization has remarkable impact on the occurrence,persistence and outcomes of inflammatory reactions.The imbalance of macrophage polarization may aggravate the inflammatory reactions of the diabetic mellitus patients,which therefore exacerbate the symptoms of the DFUs patients and bring more diffi-culties to the treatment.The adjustment of macrophage polarization may facilitate the improvement of symptoms and treatment.The influencing factors for the macrophage polarization and some of potential treatment measures for DFUs targeting the adjustment of macrophage polarization were reviewed in the article.
