Methods: Cervical radiographs were analyzed. EOP hyperplasia was classified into three subtypes with standardized length measurements. Variables encompassed demographics, ONL-related indices, and sagittal parameters. Subtype comparisons and multivariate regression analyses (with EOP length as dependent variable) were conducted. Results: Analysis of 187 CSM patients (64.2% male) identified gender-specific patterns: males exhibited greater EOP length (9.4±6.8 mm vs. 4.6±3.4 mm, p<0.001). Type III EOP demonstrated male predominance (82.4% vs. type I 31.8%, type II 51.4%; p<0.001), with associated longer hyperplasia length (11.6±6.6 mm vs. type II 5.1±1.9 mm, p<0.001). Type III EOP was associated with higher ONL prevalence (type III 64.8% vs. type I 45.5%, type II 41.9%; p=0.010) and longer ONL osteophyte length (type III 18.8±9.8 mm vs. type I 14.2±8.1 mm, type II 14.2±9.4 mm; p=0.046). Multivariate regression confirmed male sex (β=–3.82, p=0.009), ONL osteophyte length (β=0.16, p=0.017), T1 slope (β=0.27, p=0.041), and spino-cranial angle (β=–0.19, p=0.009) as factors independently associated with EOP length (adjusted R²=0.382). Conclusions Severe EOP hyperplasia exhibits a male-predominant distribution pattern and demonstrates significant radiological associations with ONL and cervical sagittal imbalance in CSM patients. These findings advocate for EOP evaluation in clinical evaluations to identify high-risk biomechanical profiles.

Methods: From March 2020 to March 2023, 100 inpatients with DS were classified into groups A, B, C, and D based on the CARDS classification system. Preoperative radiological data were analyzed to measure the severity of central canal stenosis, facet joint arthropathy, intervertebral disc herniation, and spinal epidural lipomatosis, osteophyte formation, range of motion (ROM), and computed tomography value of the vertebral bodies. The radiological characteristics and clinical contraindications for OLIF were compared among the groups. Results: Of the 100 patients, 51% had clinical contraindications for OLIF, which included 85%, 25%, 62.5%, and 20% of patients in groups A, B, C, and D, respectively. Compared with group B, group A demonstrated greater severity of central canal stenosis, whereas group C showed a higher degree of facet joint arthropathy. More patients in groups A and C had severe central canal stenosis. Regarding the ROM results, group A had segmental stiffness, whereas group D presented relatively unstable slip segments. Conclusions Patients with different DS subtypes have varied radiological characteristics. Groups B and D are suitable candidates for OLIF. Most patients in group A are unsuitable for OLIF because of bony hyperplasia, severe spinal stenosis, and segmental stiffness.

Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Objective:To screen the key genetic,diagnostic and therapeutic targets of chronic obstructive pulmonary disease(COPD)patients by using microarray datasets and Mendelian randomization(MR)method,and to provide the evidence for clinical diagnosis and treatment of COPD.Methods:Four COPD gene expression profile datasets were obtained from the Gene Expression Omnibus(GEO)database.The data were processed and normalized using R software,and differentially expressed genes(DEGs)were screened.MR analysis was performed to explore the causal relationship between COPD and expression quantitative trait loci(eQTL),intersection with DEGs was taken to identify potential key targets.Gene Set Enrichment Analysis(GSEA),Gene Ontology(GO)functional enrichment analysis,and Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling pathway enrichment analysis were conducted to investigate the functional roles and pathways of the key targets,external datasets were used to validate their expression.Results:A total of 1 571 DEGs were screened,including 820 upregulated genes and 751 downregulated genes.MR analysis identified 286 COPD-related genes,and intersection with DEGs revealed 3 upregulated genes:diacylglycerol kinase gamma(DGKG),neurofilament heavy polypeptide(NEFH),and Fc receptor like B(FCRLB);and 6 downregulated genes:STEAP4 metalloreductase(STEAP4),pleckstrin homology domain containing family F member 2(PLEKHF2),CD3d molecule(CD3D),transgelin 2(TAGLN2),tripartite motif containing 22(TRIM22),and ribosomal protein L9(RPL9).The biological function analysis results indicated that these genes were mainly involved in pathways such as iron ion transport into the cells,oxidoreductase activity,primary immunodeficiency,and Th1 and Th2 cell differentiation.The MR analysis results confirmed the causal relationship between these targets and COPD.The external validation results showed that compared with healthy controls,the expression level of FCRLB in COPD samples was significantly increased(P<0.01),while the expression levels of CD3D and RPL9 were significantly decreased(P<0.05 or P<0.01),which was consistent with the MR analysis results,highlighting the reliability of this study.Conclusion:DGKG,NEFH,FCRLB,STEAP4,PLEKHF2,CD3D,TAGLN2,TRIM22,and RPL9 may serve as important regulatory factors and clinical diagnostic/therapeutic targets in the pathogenesis of COPD,providing clues for early screening,diagnosis,and targeted treatment of COPD.

Objective To explore the predictive value of serum C-reactive protein(CRP)/albumin(Alb)ratio,cystatin C(CysC),procalcitonin(PCT),and serum amyloid A(SAA)levels for urinary tract infection after percutaneous nephrolithotripsy in patients with upper urinary tract calculi.Methods A retrospective se-lection was made of 127 patients with upper urinary tract calculi who underwent percutaneous nephrolithotrip-sy in this hospital from January 2021 to January 2024 as the research subjects.The patients were divided into the infection group(n=66)and the non-infection group(n=61)according to their postoperative urinary tract infection conditions.Analyze the distribution of pathogenic bacteria in the infection group,as well as the com-parison of clinical data,CRP/Alb ratio,CysC,PCT and SAA levels between the two groups.Multivariate Lo-gistic regression was used to analyze the influencing factors of postoperative urinary tract infection in patients.The receiver operating characteristic(ROC)curve was used to analyze the predictive value of CRP/Alb ratio,CysC,PCT and SAA levels for postoperative urinary tract infection in patients.Results The pathogenic bacte-ria in the infection group were mainly Gram-negative bacteria[44(66.67％)].The proportions of smoking history and operation duration ≥60 minutes in the infection group were higher than those in the non-infection group,and the difference was statistically significant(P＜0.05).The CRP/Alb ratio,CysC,SAA and PCT levels in the infection group were higher than those in the non-infection group,and the difference was statisti-cally significant(P＜0.05).The results of multivariate Logistic regression analysis showed that smoking his-tory,operation duration ≥60 min,upregulation of CRP/Alb ratio,CysC,SAA,and PCT levels were risk fac-tors for postoperative urinary tract infection in patients(P＜0.05).The results of ROC curve analysis showed that the combined prediction of CRP/Alb ratio,CysC,SAA and PCT for postoperative urinary tract infection in patients had a sensitivity of 89.41％,a specificity of 90.22％,and an area under the curve(AUC)of 0.933.The AUC of the combined prediction was higher than that of the individual predictions of CysC,SAA and PCT(Z=3.564,2.846,2.644,P＜0.05).Conclusion The serum CRP/Alb ratio,CysC,PCT,and SAA levels have important predictive value for urinary tract infection after percutaneous nephrolithotripsy in patients with up-per urinary tract calculi.

With the rising incidence of cervical kyphosis, the clinical understanding of this condition has evolved. Studies have shown that a subset of asymptomatic individuals exhibit cervical kyphosis, indicating that not all cases represent pathological changes. A thorough understanding of the common causes, underlying mechanisms, and imaging criteria for pathological cervical kyphosis is essential for establishing a tiered treatment model. Proficiency in stiffness assessment, clinical classification systems, and cervical osteotomy techniques is crucial for surgical planning and complication prevention. However, several key issues remain unresolved, including the optimal surgical approach for rigid cervical kyphosis, sagittal alignment correction targets, and long-term postoperative outcomes. Addressing these challenges requires high-quality clinical research to refine treatment strategies and improve patient care.
