科学领域:
- 肺部病理学 肺部病理学
- 移植免疫学 移植免疫学
- 组织病理学 组织病理学
背景情况:
- 慢性肺异位移植功能障碍 (CLAD) 是肺移植 (LuTX) 后的一个主要并发症,导致显著的死亡率.
- 膜隔膜扩大 (ASW) 在活检上与急性幽默排斥有关,这表明它可能是早期CLAD预测因素.
研究的目的:
- 为了确定预先症状的组织学标志物来预测LuTX后的CLAD发展.
- 探索ASW,原表达和LuTX接受者的肺功能下降之间的关联.
主要方法:
- 在多个时间点对57名LuTX患者的横支气管活检进行了回顾性分析.
- 微观形态测量和定量逆转录PCR用于评估ASW和基因表达 (COL1A1,COL3A1).
主要成果:
- 早在LuTX后的一年,在患有CLAD (p < 0.001) 的患者中观察到ASW的增加.
- 在较晚的时间点上较高的ASW显著预测了生存率 (HR 1.885).
- 增加的 COL1A1 和 COL3A1 表达与增加的 ASW 和 CLAD 发育相关,同时降低了 DLCO.
结论:
- ASW是一种有价值的前症状组织学标志物,用于早期评估LuTX患者的CLAD风险.
- 这种可访问的横支气管活检标志物反映了预测CLAD的连续对细胞变化.

01:24External and Internal Respiration
External respiration occurs in the lungs, and it is the first step in the journey of oxygen inside the body. When we inhale, oxygen enters our lungs and diffuses across the thin alveolar membrane. The alveoli are tiny, air-filled sacs that provide a vast surface area for gas exchange. Oxygen in the alveoli has a higher partial pressure (105 mmHg) than in the adjacent pulmonary capillaries (40 mmHg), establishing a pressure gradient. As a result, oxygen molecules move from the alveoli into the...
01:10Atelectasis II: Pathophysiology
Atelectasis develops when alveoli lose their air and collapse inward. Because lung tissue is naturally elastic, these air sacs shrink rather than remaining open. Collapsed alveoli are no longer ventilated, reducing their role in gas exchange. Blood flow may continue in these regions, creating a ventilation–perfusion mismatch. Clinical findings include decreased breath sounds, dullness to percussion, reduced chest expansion, and decreased tactile fremitus as sound transmission through collapsed...
01:23Chronic Obstructive Pulmonary Disease II: Emphysema
Emphysema, a major phenotype of chronic obstructive pulmonary disease (COPD), is characterized by irreversible destruction of alveolar walls and permanent enlargement of distal airspaces. Unlike chronic bronchitis, which primarily affects the airways, emphysema predominantly involves the lung parenchyma, where structural damage leads to airflow limitation.PathophysiologyIt most commonly results from prolonged exposure to cigarette smoke and other toxic gases, particularly cigarette smoke.
