Study phase:

N/A

研究设计:

病例对照研究 

Study design:

Case-Control study 

研究目的:

(1)明确COPD患者BALF中LC3、Beclin-1、PINK1/Parkin的表达特征,并与健康对照组比较。 (2)分析自噬相关蛋白与疾病严重程度(GOLD分级、急性加重频率、CAT评分)的相关性,评估其作为生物标志物的潜力。 (3)探索自噬-炎症交互作用,如LC3与IL-6、TNF-α的关系,揭示自噬调控COPD炎症的机制。 (4)结合PINK1/Parkin表达,评估线粒体自噬在COPD肺损伤中的作用,为靶向干预提供依据。  

Objectives of Study:

(1) Determine the expression characteristics of LC3, Beclin-1, and PINK1/Parkin in BALF of COPD patients and compare them with those of a healthy control group. (2) Analyze the correlation between autophagy-related proteins and disease severity (GOLD grading, frequency of acute exacerbations, CAT score), and evaluate their potential as biomarkers. (3) Explore the autophagy-inflammatory interaction, such as the relationship between LC3 and IL-6, TNF-α, to reveal the mechanism by which autophagy regulates inflammation in COPD. (4) Combine PINK1/Parkin expression to evaluate the role of mitophagy in COPD-related lung injury, providing a basis for targeted intervention.
