科学领域:
- 类风湿病学 类风湿病学
- 医疗成像医学成像
- 生物物理学的生物物理.
背景情况:
- 系统性硬化症 (SSc) 是一种复杂的自身免疫性疾病,其特征是皮肤变厚和纤维化.
- 准确评估皮肤硬度对于诊断和监测SSc.的疾病进展至关重要.
- 目前用于评估皮肤硬性的方法,例如修改后的罗丹皮肤评分 (mRSS),在客观性和可靠性方面存在局限性.
研究的目的:
- 评估剪切波弹性图 (SWE) 在量化SSc.患者的皮肤硬性的有效性.
- 确定SWE测量与SSc疾病活动的临床和组织学标志物之间的相关性.
- 评估SWE在区分SSc与SSc类疾病中的诊断价值,并将其灵敏度与现有的诊断标准进行比较.
主要方法:
- 剪切波弹性图 (SWE) 在66名SSc患者,100名健康对照者和27名SSc类疾病患者身上在17个修改的罗丹皮肤评分 (mRSS) 测量站点进行.
- 组之间比较了SWE值,并分析了与总mRSS的相关性,欧洲硬化皮肤研究小组疾病活动指数和组织学原沉积的相关性.
- 用接收器操作特征 (ROC) 曲线分析评估SSc的SWE诊断性能,并与1980年美国风湿病学会 (ACR) 标准进行比较.
主要成果:
- 在所有17个mRSS地点,SWE值在SSc患者中明显高于健康个体.
- 在SSc患者中,即使在临床上不涉及的皮肤部位 (mRSS=0) 中也观察到升高的SWE值.
- SWE与总mRSS (r=0.783),疾病活性指数 (r=0.707) 和原沉积 (r=0.749) 显示出强烈的正相关性.

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies
38
The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Elastic Strain Energy for Shearing Stresses
216
As discussed in previous lessons, strain energy in a material is the energy stored when it is elastically deformed, a concept crucial in materials science and mechanical engineering. This energy results from the internal work done against the cohesive forces within the material. When a material undergoes shearing stress and corresponding shearing strain, the strain energy density, which is the energy stored per unit volume, is calculated. Within the elastic limit, where the stress is...

Imaging Studies for Cardiovascular System I:Echocardiography
368
Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...
