简要总结
This study, based on previous registration records, aims to explore the syndrome patterns, disease characteristics, and their interrelationships of IPF at different stages, grades, and in its natural course, thus providing a multidimensional interpretation of the syndrome patterns and characteristics of IPF.
详细描述
This study, based on previous registration records, uses a cross-sectional survey design to collect demographic information, disease-related data, syndrome data, and auxiliary examination data from 2864 IPF patients in China. It aims to elucidate the syndrome types, disease characteristics, and the interrelationships between them of IPF at different stages, grades, and in its natural course.

结局指标
主要结局
Disease Stage
时间窗: Evaluate at baseline.
Recording the disease staging of IPF patients. According to the Adult Idiopathic Pulmonary Fibrosis (Revised Edition) and Progressive Pulmonary Fibrosis: ATS/ERS/JRS/ALAT Official Clinical Practice Guidelines (2022 Edition), and the Chinese Expert Consensus on the Diagnosis and Treatment of Acute Exacerbation of Idiopathic Pulmonary Fibrosis, the disease staging evaluation of IPF is stable phase or acute exacerbation.
Gender, age and physiologic variables (GAP)stage
时间窗: Evaluate at baseline.
Recording the GAP stage of IPF patients. GAP stage is a risk stratification method that quantifies the three core parameters of patients: gender, age, and physiological parameters, by calculating the total score and conducting risk stratification.
Pulmonary function classification
时间窗: Evaluate at baseline.
Recording the pulmonary function classification of IPF patients. According to The Expert Consensus on the Diagnostic Criteria for Adult Lung Function in China, pulmonary function classification is divided into mild, moderate, and severe grades.
Natural course
时间窗: Evaluate at baseline.
Recording the natural course of IPF patient. According to international research, the natural course of IPF can be divided into stable, slow progression, rapid progression, and recurrent acute exacerbation. The specific criteria are as follows: 1.stable: FVC annual decline\<0.13L; 2. stable slow progression: FVC annual decline 0.13L-0.21L; 3. Rapid progress: FVC annual decline\>0.21L; 4. Recurrent acute exacerbations: Annual number of acute exacerbations ≥ 1.
The Traditional Chinese Medicine(TCM) Syndromes
时间窗: Evaluate at baseline.
Evaluate traditional Chinese medicine syndromes by collecting patients' symptoms, signs, and tongue pulse information.
6 Six Minute Walk Distance(6MWD)
时间窗: Evaluate at baseline.
6MWD will be applied to evaluate the exercise capacity. The higher values indicate the better exercise capacity.
The 30 - second sit - to - stand test(30s STS)
时间窗: Evaluate at baseline.
The 30 second sitting and standing test will be used to evaluate lower limb strength and cardiopulmonary function.
A Tool to Assess Quality of life (ATAQ-IPF) total scores
时间窗: Evaluate at baseline.
ATAQ-IPF is currently a specialized scale for evaluating the quality of life, consisting of 13 dimensions and 74 items, with each item scored on a 1-5 scale. The higher the score, the worse the quality of life.
St. George's respiratory questionnaire (SGRQ) total scores
时间窗: Evaluate at baseline.
SGRQ is a scale used to evaluate the quality of life of patients, which includes three dimensions: symptoms, mobility, and the impact of disease on daily life, with a total of 50 items. The total score range of SGRQ is usually between 0 and 100, with higher scores leading to poorer quality of life.
Dyspnea
时间窗: Evaluate at baseline.
Dyspnea will be assessed by modified Medical Research Council(mMRC) scores. A score of 0-4 will be givenaccording to the degree of immediate dyspnea. A higher score indicates a worse condition.
C-reactive protein (CRP)
时间窗: Evaluate at baseline.
The CRP level will be detected by ELISA technology.
Krebs Von den Lungen-6（KL-6）
时间窗: Evaluate at baseline.
The KL-6 level will be detected by ELISA technology.
The pulmonary artery systolic pressure(PASP)
时间窗: Evaluate at baseline.
The PASP will be measured byechocardiogram.
The diameter of the pulmonary artery
时间窗: Evaluate at baseline.
The diameter of the pulmonary artery will be measured byechocardiogram.
Forced vital capacity (FVC)
时间窗: Evaluate at baseline.
FVC will be applied to assess pulmonary function.
FVC as the percentage of the predicted value (FVC%)
时间窗: Evaluate at baseline.
FVC% will be applied to assess pulmonary function.
Diffusing capacity of the lungs for carbon monoxide (DLCO)
时间窗: Evaluate at baseline.
DLCO will be applied to assess pulmonary function.
DLCO as the percentage of the predicted value (DLCO%)
时间窗: Evaluate at baseline.
DLCO% will be applied to assess pulmonary function.
