研究目的:

本研究拟阐明人体镉负荷水平对肺纤维化患者肺功能进展、急性加重及生存结局的影响,为揭示环境金属暴露与间质性肺病相互作用机制提供临床证据。  

Objectives of Study:

This study aims to clarify the impact of human cadmium burden levels on lung function progression, acute exacerbation, and survival outcomes in patients with pulmonary fibrosis, thereby providing clinical evidence for revealing the interaction mechanism between environmental metal exposure and interstitial lung disease.
