Diagnostic criteria for their main types of nontuberculous other lung diseases can be found in Annex 3; (5)Community healthy people without other lung diseases: those who have no history of tuberculosis, no suspicious symptoms of tuberculosis, no history of respiratory tract and recent respiratory symptoms, and no obvious abnormalities in both lungs on chest imaging (DR) examination; After consultation, there is no history of heart, liver, kidney, digestive tract, nervous system, or psychiatric abnormalities.
