Lung function test was performed on the subjects with Jaeger lung function instrument of Germany.
This Jaeger lung function instrument of Germany is used to test the pulmonary ventilation function of COPD patients. Since the condition requires drug control and treatment, the drug cannot be stopped.
Agilent 1290 Infinity LC system (UHPLC, Santa Clara CA) was used for Targeted metabolite detection.
We used the Agilent 1290 Infinity LC system mass spectrometer to analyze and detect metabolite peaks of patients according to retention time and mass/charge ratio after preliminary experiments and derivatization.
