概括
在患有腹腔大动脉动脉瘤 (AAA) 的患者中,可溶性莱克样氧化低密度脂蛋白受体-1 (sLOX-1) 水平较高,但无法预测AAA大小或破裂风险. 大动脉LOX-1表达在AAA中增加,可能抵消破裂.
科学领域:
- 血管生物学 血管生物学
- 生物标志物发现发现
- 动脉样硬化研究 动脉样硬化研究
背景情况:
- 腹腔大动脉瘤 (AAA) 的手术修复是以直径为依赖的.
- 类似乳清素的氧化低密度脂蛋白受体-1 (LOX-1) 是氧化LDL吸收和动脉样硬化的关键.
- 可溶性LOX-1 (sLOX-1) 是心血管疾病中的潜在生物标志物.
研究的目的:
- 在AAA中调查LOX-1调节.
- 在AAA患者中评估sLOX-1的诊断和风险分层实用性.
主要方法:
- 病例控制研究比较AAA (n=104) 和外周动脉疾病 (n=104) 患者中的sLOX-1.
- 根据年龄,并发症和药物进行统计调整.
- 对大动脉LOX-1mRNA表达的分析及其与细胞和矩阵组件的相关性.
主要成果:
- 在多变量调整后,AAA患者的血清sLOX-1较高.
- sLOX-1与AAA直径,体积或血栓厚度没有相关性.
- 大动脉LOX-1mRNA表达在AAA中升高,并与光滑肌肉的活性蛋白,原蛋白和巨细胞相关.
结论:
- 在AAA中sLOX-1水平受到年龄,心脏代谢疾病和治疗的影响.
- sLOX-1不是AAA风险分层的可靠生物标志物.
- 动脉瘤LOX-1表达的增加可能对AAA破裂起着保护作用.

Aneurysm I: Introduction
15
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

Atherosclerosis I: Introduction
11
Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...
