肺栓塞患者血浆D-二聚体水平及其他指标与远期全因死亡率的关系
Zhongguo shiyan zhenduanxue, 2023 目的 探讨肺栓塞患者血浆D-二聚体水平及其他指标是否可以预测肺栓塞(PE)患者的长期全因死亡率。方法 选取2017年1月至2022年12月期间在吉林大学第一医院乐群院区住院的308名PE患者，根据结局分为生存组(n=205)和死亡组(n=103)。构建ROC曲线以预测全因死亡率的最佳D-二聚体截断值。计算AUC并获得全因死亡率的预测灵敏度和特异度。建立多因素logistic回归模型来评估D-二聚体水平与全因死亡率的关系。通过绘制Kaplan-Meier曲线显示D-二聚体水平与累积生存时间的关系 ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The poor soft tissue integration around titanium implants creates a microgap that serves as a pathway for pathogen invasion, resulting in infection, inflammation, and the progression of peri‐implantitis. As the implant’s transmucosal component, the abutment determines the degree of peri‐implant soft tissue attachment.

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The urgent environmental crisis caused by polyethylene terephthalate (PET) waste necessitates efficient upcycling strategies. Herein, we establish a novel pathway to transform waste PET plastic into a high‐performance catalytic material for mediating the oxygen evolution reaction (OER). Through a one‐step hydrothermal process, waste PET serves
