概括
大动脉置换组之间的系统性炎症反应综合征 (SIRS) 发生率相似. 内皮微粒 (EMP) 在手术后增加,而特定的白内素在常规生物假体中更高.
科学领域:
- 心血管外科心血管外科
- 生物标志物 生物标志物
- 炎症研究 炎症研究
背景情况:
- 系统性炎症反应综合征 (SIRS) 与循环内皮微粒 (EMP) 的升高有关.
- 大动脉置换 (AVR) 是一种常见的心脏手术,具有潜在的炎症后果.
研究的目的:
- 为了比较使用PercevalTM S进行AVR的患者的血EMP度与传统生物假体.
- 评估EMP水平对AVR后短期炎症反应的影响.
主要方法:
- 一项随机临床试验,涉及24名接受隔离AVR的患者,分为PercevalTM S (P组) 和常规生物假体 (C组) 组.
- 分析SIRS发病率,EMP概况,白细胞间蛋白 (IL-6,IL-8),C反应蛋白,以及手术前和24小时,手术后3个月的甲酸.
主要成果:
- 两组之间严重SIRS发病率没有显著差异 (C组的66.7%,P组的50%).
- 在手术后24小时,EMP水平显著增加,在两组中,在三个月内恢复到基线.
- 在手术后24小时,常规生物假体组 (C组) 观察到较高的IL-6和IL-8水平.
结论:
- 在AVR期间,PercevalTM S和传统生物假体之间的严重SIRS发病率是可比的.
- 虽然在两组中,EMP水平在AVR后上升,但传统的生物假体与更高的短期IL-6和IL-8水平有关.
- 三个月后EMP水平正常化,这表明无论假肢类型如何,术后反应都是暂时的.

Inflammation
Overview
Inflammatory Response I: Vascular and Cellular
The inflammatory response is the body's defense against infection, injury, or irritation from bacteria, trauma, toxins, or heat. Inflammation helps locate and destroy pathogens and remove damaged tissue elements to heal the body. During this initial phase, fluid, blood products, and nutrients migrate to the injured area, resulting in redness, heat, swelling, ache, and loss of function. Moreover, signs of systemic inflammation include fever, increased WBC count, malaise, anorexia, nausea,...
Inflammatory Response
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Inflammation: Introduction
Inflammation is a fundamental, protective biological response of vascularized tissues to cellular injury, infection, or harmful stimuli. Its primary function is to eliminate the initial cause of injury, clear necrotic cells and damaged tissue, and initiate the necessary repair processes.Cardinal SignsAcute inflammation presents with classic signs. Redness results from vasodilation and increased blood flow. Heat is due to increased metabolism and circulation. Swelling results from the...
Acute Inflammation I: Inflammatory Response
Acute inflammation is a rapid, short-lived physiological response to tissue injury or infection, designed to eliminate harmful agents and initiate repair. This tightly regulated process typically lasts from minutes to several days and is triggered by factors such as microbial invasion, physical trauma, or chemical injury.Recognition and Mediator ReleaseThe inflammatory response begins when resident immune cells—such as mast cells, macrophages, and dendritic cells—detect damage-associated...
Hypersensitivity Reactions: Immune-Complex Reactions
Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum sickness, a systemic...
