研究目的: |
本项目拟围绕非COPD吸烟人群构建包含3年随访的前瞻性队列,纳入符合纳排标准的受试者,定期(每年体检时)采集其临床信息和生物样本(包括血清、痰液、粪便、尿液,仅针对部分有临床操作需求的患者采集肺泡灌洗液和肺组织),并进行生活质量评分、肺功能(包括常规肺功能和脉冲振荡IOS肺功能)测试、影像学检查(HRCT、SPECT),评估受试人群临床进展情况,挖掘COPD早期进展标志性事件。 |
||||||||||||||||||||||
|
Objectives of Study: |
Subjects who met the inclusion and exclusion criteria were enrolled. Clinical information and biological samples (including serum, sputum, feces and urine) were collected regularly (during annual physical examination), and alveolar lavage fluid and lung tissue were collected only for some patients with clinical operation requirements. The quality of life score, pulmonary function test (including routine pulmonary function test and impulse oscillometry IOS pulmonary function test), imaging examination (HRCT, SPECT) were performed to evaluate the clinical progress of the subjects, and to explore the landmark events of early COPD progression. |
