不同剂量血管紧张素-（1-7）对心力衰竭大鼠心室有效不应期及心室颤动阈值的影响 [PDF]
Zhongshan Daxue xuebao. Yixue kexue ban, 2006 【目的】观察不同剂量血管紧张素-（1-7）对慢性心力衰竭大鼠心室有效不应期及心室颤动阈值的影响。【方法】40只Wistar大鼠成功建立慢性心力衰竭模型，随机分为心力衰竭组（n=10）、心力衰竭并血管紧张素-（1-7）处理3个剂量组（每组n=10）。另取10只Wistar大鼠行假手术，为正常对照组。用心电生理研究方法测定心室有效不应期（VERP）、心室颤动阈值（VFT）的变化，比较心力衰竭并血管紧张素-（1-7）处理的3个剂量组、心力衰竭组及正常对照组各项指标。【结果】心力衰竭大鼠VERP（73．5ms ...

Zhongshan Daxue xuebao. Yixue kexue ban, 2004 【目的】 探讨慢性心力衰竭患者血清瘦素水平改变及其与胰岛素抵抗?胰岛素水平之间的关系? 【方法】 观察60例慢性心力衰竭患者及30例正常对照组血清瘦素水平变化,分析血清瘦素与胰岛素抵抗(以I-AI表示)?胰岛素水平之间的关系? 【结果】 慢性心力衰竭组血清瘦素水平较正常对照组明显升高(12.0±3.4)ng/mL vs (6.3±2.0) ng/mL, P < 0.01?与对照组相比,慢性心力衰竭组胰岛素浓度升高(24.1±5.5) ×10-3 U/L vs (13.9±3.1) ×10-3U/L, P

Journal of Diabetes, Volume 15, Issue 11, Page 968-977, November 2023., 2023 Highlights Among 301 studies, diabetes mellitus was the most studied cardiometabolic risk factor. In the network meta‐analysis, cerebrovascular disease had the highest impact (relative risk [RR] 1.69; 95% CI, 1.65–1.73) on COVID‐19 outcomes compared to other cardiometabolic risk factors.

Journal of Diabetes, Volume 15, Issue 1, Page 27-35, January 2023., 2023 Highlights This study constructed the first 5‐year all‐cause mortality risk prediction model for patients with type 2 diabetes mellitus in south China. This well‐performing model, using highly accessible predictors collected in routine clinical settings, provides a powerful tool for clinicians to identify high‐risk diabetic patients.

Implications of fetal premature atrial contractions: systematic review
Ultrasound in Obstetrics &Gynecology, Volume 60, Issue 6, Page 721-730, December 2022., 2022 ABSTRACT Objective Fetal heart‐rate irregularities occur in 1–2% of pregnancies and are usually caused by premature atrial contractions (PAC). Although PAC are considered benign, they may be associated with cardiac defects and tachyarrhythmia. We aimed to determine the incidence of congenital heart defects (CHDs) and complications in fetuses with PAC ...
