摘要： Left ventricular (LV) mass is a well-established prognostic indicator for cardiovascular risk. Measurement of LV mass on coronary computed tomography angiography (CCTA) is considered optional. We aimed to assess for associations between LV mass measured on CCTA with all-cause mortality (ACM) risk and to determine age- and sex-specific distributions.

摘要： Multivessel coronary artery disease (MVD) represents a common finding at invasive coronary angiography (ICA) among out-of-hospital cardiac arrest (OHCA) survivors. However, optimal invasive treatment strategy for MVD in OHCA remains unknown. Our study aims to assess if complete revascularization improves one-year clinical outcomes in these patients.

关键词： Higher-order mesh generation   Curvilinear mesh   Mesh optimization   Minimal surface  

摘要： This paper presents a novel method for generating higher-order meshes for CAD surfaces by leveraging minimal surface theory to improve element shapes. We explore the concept of higher-order mesh distortion through deformation gradients and introduce an energy function designed to minimize the surface area of these meshes, providing a theoretical justification for its effectiveness in untangling. The process of mesh generation starts with segmenting CAD surfaces into linear elements, followed by the insertion of higher-order nodes within these elements. These nodes are then projected onto the CAD surface to form the initial higher-order elements. By optimizing energy functions related to minimal surfaces and the projection distances, we achieve high-quality, geometrically accurate higher-order surface meshes. Our method has been validated on complex geometries, showcasing its potential in creating effective higher-order meshes for industrial CAD models.

关键词： Treg   CAD   T2DM   Immunology   TGF-β   IL-10  

摘要： Patients with coronary artery disease (CAD) combined with type 2 diabetes mellitus (T2DM) develop serious atherosclerotic and diffuse lesions. Inadequate numbers and the dysfunction of CD4⁺CD25⁺Foxp3⁺regulatory T lymphocytes (Treg cells) are common mechanisms underlying the immunopathological damage in CAD and T2DM.

关键词： GPT-4o   radiology report   CAD-RADS   coronary computed tomography angiography (CCTA)   free-text reports  

摘要： Despite the Coronary Artery Reporting and Data System (CAD-RADS) providing a standardized approach, radiologists continue to favor free-text reports. This preference creates significant challenges for data extraction and analysis in longitudinal studies, potentially limiting large-scale research and quality assessment initiatives.

关键词： 全瓷冠修复   CAD/CAM氧化锆全瓷冠   前牙美学  

摘要： 目的 探讨CAD/CAM氧化锆全瓷冠修复对前牙美学修复患者美学效果及功能恢复情况的影响.方法 选取我院2023年10月-2024年10月收治的60例前牙美学修复患者,应用随机数字表法分为观察组(30例)和对照组(30例).对照组采用传统金属烤瓷冠修复,观察组采用CAD/CAM氧化锆全瓷冠修复,比较两组美学效果、功能恢复情况、并发症发生情况.结果 观察组术后1、6个月的美学评分高于对照组,且术后1、3、6个月咀嚼效率高于对照组(P＜0.05);观察组术后6个月美学满意率为96.67%,咀嚼功能恢复率为90.00%,均高于对照组的83.33%、83.33%(P＜0.05);观察组牙龈炎发生率、牙龈出血发生率和修复体松动发生率均低于对照组(P＜0.05).结论 相较于传统金属烤瓷冠修复,在前牙美学修复中采用CAD/CAM氧化锆全瓷冠修复更有利于提升美观效果,改善功能恢复和牙龈健康,降低并发症发生率.
