Journal of Diabetes, Volume 15, Issue 10, Page 853-865, October 2023., 2023 Highlights Few studies have investigated the association of large‐scale biomarkers and pulse wave velocity (PWV) among diabetic patients. This study investigates the relationships of serum laboratory tests with PWV and explored the associations between PWV and all‐cause mortality among diabetic patients.

, 2022 颈动脉粥样硬化是脑梗死等心血管疾病发生的主要原因。研究血液流动对其成因的影响对颈动脉粥样硬化的预防和治疗有着重要的作用。本研究数值模拟了两个不同颈动脉窦膨大程度和不同前端曲率的颈动脉模型C1、C2,研究了常规有氧运动和久坐对青年、中年、老年三个年龄组颈动脉血流的影响。模拟结果显示,在心脏跳动周期中不同时刻,有氧运动和久坐对颈动脉血流和血管壁面剪应力的影响是不同的,但并未对振荡剪切指数产生显著的影响。同时研究了有氧运动和久坐对反向流量的影响,发现在颈动脉窦膨大程度低且前端曲率高的颈动脉模型C1中 ...
