Traditional Chinese Medicine(TCM) Syndrome Classification of Idiopathic Pulmonary Fibrosis(IPF) and Metabolomics

Study Overview
=================
Brief Summary
-----------------
The pathogenesis of idiopathic pulmonary interstitial fibrosis is complex, and there is no specific biomarkers, the treatment effect is not such useful. Currently, it is discovered that Chinese medicine treatment may be effective. The investigators select patients with idiopathic pulmonary interstitial fibrosis and healthy controls, use metabolomics to study the biological characteristics of idiopathic pulmonary interstitial fibrosis, screen biomarkers of IPF, and label different TCM syndromes of IPF, explore the biological nature of IPF TCM syndromes, find the biological changes that occur during the development and progression of IPF and explore the metabolite marker clusters of IPF. Furthermore, the results of this study may find its diagnostic significance for IPF and Looking for potential targets for future treatment of IPF.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Training set<br>The training set is composed of 30 IPF patients and 15 controls. The group is designed to identify differential metabolites between IPF and control groups. | |
| Validation set<br>The validation set is composed of 15 IPF patients and 15 controls. The group is designed to validate differential metabolites identified in the previous groups. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| biomarkers detected in metabolites | Metabolomics of serum based on mass spectrometry.It is non-targeted metabolomics.The study is to find the target metabolite to distinguish IPF. | 1 year | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| High-resolution chest CT total score (CT-Tot) | High-resolution chest CT total score (CT-Tot), which includes the grid shadow and the honeycomb lung. The score range is 0-5, and the larger the score, the more serious the disease. | 1 year | 
| Six Minute Walk Test(6MWT) | The six-minute walk test measures the distance an individual is able to walk over a total of six minutes on a hard, flat surface.It is a simple objective indicator for evaluating cardiopulmonary function | 1 year | 
| Pulmonary function Pulmonary function | Pulmonary function including forced vital capacity(FVC),forced expiratory volume at one second(FEV1),diffusion capacity of lung for carbon monoxide(DLCO) | 1 year | 
| St. George's Respiratory Questionnaire | St. George's Respiratory Questionnaire is measuring impaired health and perceived well-being ('quality of life') in airways disease. the score is 0 to 100，the higher the score is，the worse life quality the patients has. | 1 year |
