The Global Initiative for Asthma (GINA) 2025 has conducted a comprehensive revision of the diagnosis and management of asthma in children aged 5 years and younger.The most important update is the first-time proposal of the specific conditions for asthma diagnosis in this age group.This article aims to interpret the relevant content of diagnosis, exacerbation management, assessment and treatment of asthma in children aged 5 years and younger in GINA 2025.It is hoped that this will provide a reference for clinical practice and enhance the management of asthma in children aged 5 years and younger.

The Global Initiative for Asthma (GINA) continues to optimize asthma treatment strategies and has introduced the concepts of anti-inflammatory reliever (AIR) and maintenance and reliever therapy(MART). AIR mainly includes Budesonide-Formoterol, Beclomethasone-Formoterol, and inhaled corticosteroids(ICS)combined with short-acting beta2-agonist.MART refers to a treatment regimen that utilizes the same ICS-Formoterol combination for both maintenance and reliever therapy.Currently, AIR and MART are recommended for the treatment of asthma in children aged 6 years and older, adolescents and adults.This article provides an interpretation of the pediatric AIR and MART content in GINA 2025, highlighting their clinical application in pediatric asthma treatment and their role in asthma action plans, with the aim of providing a reference for clinicians to optimize the treatment of pediatric asthma.

Pleckstrin homology-like domain family A member 1(PHLDA1)is a pro-apoptotic factor as well as a key regulator of metabolic diseases.In obesity-related diseases,PHLDA1 can reduce liver triglyceride production through inhibition of the expression of sterol regulatory?element binding proteins?1(SREBP?1),and reduce fat syn?thesis through inhibition of peroxisome proliferator?activated receptor γ(PPARγ).However,in cardiovascular dis?eases,PHLDA1 increases vascular calcification,dysfunction,thereby aggravates ischemia?reperfusion injury in the heart and brain.The dual role of PHLDA1 has also been confirmed in tumors.In summary,PHLDA1,as a multi?functional factor,plays different functional roles through various mechanisms.

Objective:To establish and assess the quality control and improvement system for metabolic and bariatric surgery in Beijing.Methods:Based on relevant documents from the National Health Commission and the Beijing Municipal Health Commission,and referencing the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) by the American Society for Metabolic and Bariatric Surgery,a quality control system was developed under the Beijing Quality Control and Improvement Center of Metabolic and Bariatric Surgery. The system incorporated on-site evaluations,data registration,and specialized training. From May to December 2023,on-site assessments were conducted at 21 hospitals in Beijing performing bariatric surgery,evaluating personnel qualifications,infrastructure,clinical workflows,and postoperative follow-up. A quality control database was created to collect real-time surgical data,and training was provided for data entry and professional skills. Assessment results were classified as excellent,qualified,or needing improvement,with rectification suggestions offered and follow-up visits conducted to track progress.Results:All 21 hospitals achieved a 100% compliance rate for surgical indications, 16 (76.2%) met standardized surgical operation criteria,and 14 (66.7%) had standardized postoperative management. However,only 5 (23.8%) achieved a 12-month postoperative follow-up rate of ≥60%,and 4 (19.1%) had established specialized databases. Key challenges included insufficient specialized staffing (19.1%), lack of multidisciplinary collaboration (47.6%), inadequate equipment (57.1%), and low follow-up rates (57.1%). The database collected data from over 2 000 patients across 111 fields. After rectification, specialized database coverage rose to 61.9% (13 hospitals). Multi-level training programs developed backbone physicians and specialized nurses,significantly addressing the shortage of specialized personnel.Conclusion:The quality control system established in this study,through the integration of on-site evaluation,data registration,and specialized training,effectively enhances the standardization of surgical practices and data management capabilities.

Introduction::Observational studies have revealed an association between waist circumference (WC) and atrial fibrillation (AF). However, it is difficult to infer a causal relationship from observational studies because the observed associations could be confounded by unknown risk factors. Therefore, the causal role of WC in AF is unclear. This study was designed to investigate the causal association between WC and AF using a two-sample Mendelian randomization (MR) analysis.Methods::In our two-sample MR analysis, the genetic variation used as an instrumental variable for MR was acquired from a genome-wide association study (GWAS) of WC (42 single nucleotide polymorphisms with a genetic significance of P <5 × 10 –8). The data of WC (from the Genetic Investigation of ANthropometric Traits consortium, containing 232,101 participants) and the data of AF (from the European Bioinformatics Institute database, containing 55,114 AF cases and 482,295 controls) were used to assess the causal role of WC on AF. Three different approaches (inverse variance weighted [IVW], MR–Egger, and weighted median regression) were used to ensure that our results more reliable. Results::All three MR analyses provided evidence of a positive causal association between high WC and AF. High WC was suggested to increase the risk of AF based on the IVW method (odds ratio [OR] = 1.43, 95% confidence interval [CI], 1.30–1.58, P = 2.51 × 10 -13). The results of MR–Egger and weighted median regression exhibited similar trends (MR–Egger OR = 1.40 [95% CI, 1.08–1.81], P = 1.61 × 10 -2; weighted median OR = 1.39 [95% CI, 1.21–1.61], P = 1.62 × 10 -6). MR–Egger intercepts and funnel plots showed no directional pleiotropic effects between high WC and AF. Conclusions::Our findings suggest that greater WC is associated with an increased risk of AF. Taking measures to reduce WC may help prevent the occurrence of AF.

Objective:To develop an imaging-assisted diagnostic tool for schizophrenia based on multimodal magnetic resonance imaging and artificial intelligence techniques.Methods:Three independent datasets were utilized. For each subject, four brain structural metrics including grey matter volume (GMV), white matter volume (WMV), cortical thickness (CT) and deformation-based morphometry (DBM) indicators were extracted from the structural magnetic resonance imaging (sMRI) data, and three brain functional metrics including amplitude of low frequency fluctuation (ALFF), regional homogeneity (ReHo) and functional connectivity (FC) were extracted from the functional magnetic resonance imaging (fMRI) data. To distinguish patients with schizophrenia and healthy controls, single-metric classification models and multi-metrics-fusion classification models were trained and tested using a within-dataset and a between-dataset cross-validation strategy.Results:The results of within-dataset cross-validation showed that the highest accuracy of the single-metric classifications for schizophrenia diagnosis was 86.18% (FC), while the multi-metric-fusion classifications could reach an accuracy of 90.21%. The results of between-datasets cross-validation showed that the highest accuracy of the single-metric classifications for schizophrenia diagnosis was 69.02% (ReHo), while the multi-metric-fusion classifications could reach an accuracy of 71.25%.Conclusion:The functional metrics generally outperforms the structural metrics for the classification between patients with schizophrenia and heathy controls. Additionally, fusion of multi-modal brain imaging metrics can improve the classification performance. Specifically, the fusion of CT, DBM, WMV, FC and ReHo demonstrates the highest classification accuracy, which is a potential tool for imaging-assisted diagnosis of schizophrenia.
