周围血液TBNK淋巴细胞子集的变化及其与慢性阻塞性肺病急性恶化相关
1Department of Geriatrics, Zhejiang Hospital, Hangzhou, People's Republic of China.
慢性阻塞性肺病 (AECOPD) 的急性恶化与免疫系统功能障碍有关. 患有AECOPD的患者表现出T淋巴细胞减少和较低的CD4/CD8比率,这表明在疾病发展中发挥了作用.
科学领域:
- 免疫学 免疫学 免疫学
- 呼吸系统医学 呼吸系统医学
- 细胞生物学 细胞生物学
背景情况:
- 慢性阻塞性肺病 (COPD) 恶化严重影响患者的健康.
- 了解COPD急性恶化 (AECOPD) 期间的免疫变化对于开发向治疗至关重要.
研究的目的:
- 在患有AECOPD.患者的外周血液TBNK淋巴细胞子集的变化调查.
- 探索这些免疫细胞子集的变化与AECOPD的发病因子之间的联系.
主要方法:
- 一项涉及1252名住院患者的横截面研究,其中162名被诊断为AECOPD,1090名为对照.
- 对周围血液T辅助细胞,细胞毒性T细胞,B细胞,自然杀伤细胞 (NK细胞) 和总T细胞的分析.
- 计算CD4/CD8比率的方法.
主要成果:
- AECOPD组的男性和NK细胞比例较高,平均年龄增加.
- 在AECOPD组内观察到T辅助细胞,T细胞总和CD4/CD8比率的显著下降.
- 多变量逻辑回归确定了男性的性别,年龄,T细胞总比率和CD4/CD8比率作为与AECOPD发病率相关的重要因素.
结论:
- 细胞免疫功能障碍,以减少总T淋巴细胞和较低的CD4/CD8比率为特征,存在于AECOPD患者中.
- 这些免疫变化可能在AECOPD的潜在病原发生中发挥作用.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
Mode of...
Pulmonary Tuberculosis III
The first classification is based on the development of the disease, and it includes the following categories:

Chronic Inflammation
Chronic Obstructive Pulmonary Disease-IV: Assessement and Diagnostic Studies
Medical History
Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
Primary Symptoms of COPD:
Pulmonary Tuberculosis II
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
