概括
泌尿酸酶类型等离子体激活剂受体 (uPAR) 和细胞纤维素 (cFn) 显示出潜在的生物标志物,用于识别急性缺血性中风 (AIS) 患者对复合组织等离子体激活剂 (rtPA) 治疗反应较低.
科学领域:
- 生物标志物和诊断仪器
- 神经科学是一个神经科学.
- 心血管研究的心血管研究.
背景情况:
- 重组组织等离子体激活剂 (rtPA) 是急性缺血性中风 (AIS) 的主要治疗方法.
- 一大部分AIS患者对rtPA治疗的反应有限.
- 内皮细胞功能障碍是AIS的已知因素,促使对内皮细胞相关的蛋白质进行研究.
研究的目的:
- 探索内皮细胞相关的蛋白质,特别是尿素酶类型的血原激活受体 (uPAR) 和细胞纤维菌素 (cFn),作为潜在的生物标志物.
- 确定能够预测AIS患者对rtPA的低反应的生物标志物.
主要方法:
- 使用Spearman的相关性来分析PAR/cFn水平与AIS结果之间的关系.
- 尽管接受了rtPA治疗,但对rtPA的低反应被持续的糟糕的结果 (修改的兰金级别>2) 定义.
- 后勤回归评估了PAR/cFn对低rtPA反应的预测值.
- 用诱导性中风的动物模型 (老鼠) 来进一步调查 uPAR/cFn-rtPA 关系.
主要成果:
- uPAR和cFn都与有利的AIS结果正相关.
- uPAR和cFn表现出显著的能力,以识别对rtPA反应较低的患者.
- uPAR和cFn被确定为低rtPA反应的独立预测因子.
- rtPA的使用倾向于降低ischemia/reperfusion后cFn和UPAR的血水平.
结论:
- uPAR和cFn被提议作为候选生物标志物,用于识别对rtPA反应较低的AIS患者.
- 低cFn或Upar血水平可能表明患者可能尽管接受rtPA治疗,但结果不佳.

Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...

Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
