关键词： GB/T 30127   远红外纺织品   远红外发射率   测试要点  

摘要： 近年来,远红外纺织品因具有保温保健功能备受市场青睐,但消费者难以鉴别远红外纺织品。为避免假冒伪劣产品扰乱市场,保障大众消费权益,科学地测试评价远红外纺织品变得尤为重要。通过综合分析与验证认为,GB/T 30127—2013中纺织品远红外发射率测试方法是目前国内科学且适用于测试和评价纺织品远红外性能的方法,但该方法也存在一些不够细致或完善的地方。基于此,研究针对纺织品远红外发射率测试方法中的多个测试要点进行综合分析、操作细化和验证,提出多项测试技巧与实操经验,研究成果可为相关生产、检测及监管单位或部门更科学、准确地评价远红外纺织品提供参考依据。

摘要： The incidence of in-stent restenosis (ISR) remains significant at 5–10 %, despite the widespread use of drug-eluting stents. Patients with ISR frequently present with acute coronary syndrome. End-stage renal disease (ESRD) is associated with accelerated atherosclerosis, and prior studies have demonstrated worse outcomes and higher mortality rates among ESRD patients undergoing percutaneous coronary intervention (PCI) compared to those without renal insufficiency. However, contemporary data regarding outcomes of acute myocardial infarction (AMI) in the setting of ISR in ESRD patients are limited. To this end, we sought to evaluate in-hospital outcomes of AMI and ISR for ESRD patients in the United States.

摘要： 目的分析计算机辅助设计/计算机辅助制作(CAD/CAM)氧化锆全瓷精密附着体义齿修复技术在牙缺损修复中的应用效果。方法选取2023年6月—2025年6月湖南省第二人民医院收治的76例牙缺损患者,按照修复方案不同分为对照组(n=38)与观察组(n=38)。对照组采用钴铬合金烤瓷冠修复,观察组采用CAD/CAM氧化锆全瓷精密附着体义齿修复。比较两组的修复效果、牙周症状、龈沟液指标以及并发症发生情况。结果修复后3个月,观察组的修复总有效率高于对照组,牙龈指数、菌斑指数、龈沟出血指数评分及龈沟液指标白细胞介素-6、肿瘤坏死因子α和基质金属蛋白酶-8水平均低于对照组,差异有统计学意义(P<0.05)。两组的并发症总发生率比较,差异无统计学意义(P>0.05)。结论CAD/CAM氧化锆全瓷精密附着体义齿修复技术能提高牙缺损患者的修复效果,有效改善患者牙周症状,减轻龈沟液炎症反应,且安全性较高。

关键词： 脆弱纺织品   人工老化   加固材料   纤维素纤维   蛋白质纤维  

摘要： 为探究脆弱织物加固材料的适配性,选用戊二醛(GA)、乙二醇缩水甘油醚(EGDE)、丙烯酸树脂Paraloid B72(B72)、羟乙基纤维素(G-HEC)复配液、氨基硅烷偶联剂(PEI)、环氧改性硅烷偶联剂(KH560)为加固材料,文章采用浸渍法分别对棉、麻、真丝织物、毛织物开展系统性加固处理对比实验,对比分析加固前后织物的外观形貌、色差、厚度、硬挺度及拉伸强力。实验结果表明:丙烯酸树脂Paraloid B72对羊毛织物的加固效果最佳,其耐老化性能良好,断裂应力提升1.3倍,有效减缓了老化进程;经戊二醛加固处理后,真丝织物的断裂应力显著提升;G-HEC复配液加固后,棉织物断裂应力提高1.18倍,且在色差控制、硬挺度保持及厚度稳定性方面表现稳定;经PEI-KH560加固后的麻织,断裂应力显著提升,有效减缓了老化进程。由此可见,加固材料与加固基质之间存在适配性,因此在实际文物加固保护工作中,应充分考虑二者的适配性,以最大限度延缓织物劣化,延长其保存寿命。

摘要： Systemic inflammation contributes to the pathophysiology of heart failure (HF). Inflammation in heart failure with mildly reduced ejection fraction (HFmrEF) or heart failure with preserved ejection fraction (HFpEF) has been linked to cardiovascular-kidney-metabolic conditions, whereas inflammation in heart failure and reduced ejection fraction (HFrEF) is thought to develop secondary to cardiac stress and circulatory derangements.

摘要： Cancer therapies save lives but often “break hearts” by damaging the cardiovascular system. As survival improves, therapy-induced cardiotoxicity has become a defining challenge of modern oncology. Recent discoveries reveal that long non-coding RNAs (lncRNAs), once dismissed as genomic noise, are the “RNA rebels” orchestrating cellular responses to cancer treatments. These molecules act as both heartbreakers and healers, amplifying or counteracting oxidative stress, mitochondrial dysfunction, apoptosis, and vascular injury. In anthracycline, radiation, and VEGF-targeted therapies, lncRNAs govern key processes that dictate whether cells succumb to damage or mount protective repair responses. Pro-injury lncRNAs exacerbate senescence and inflammation, while protective ones preserve mitochondrial homeostasis and limit cell death. Beyond mechanistic insight, these molecules hold clinical promise as biomarkers and therapeutic targets, guiding RNA-based strategies to predict, prevent, and treat cardiotoxicity. Understanding how they blur the line between protection and harm may redefine how we safeguard the heart in the era of precision cardio oncology.
