Has received Glucocorticoid (hereinafter referred to as the "hormone") and at least one immunosuppressive therapy for more than 3 months, the hormone dosage (prednisone equivalent dose calculation) should be less than 15mg/d for at least 1 months, should be immunosuppressant cyclophosphamide, mycophenolate mofetil, cyclosporine, tacrolimus, azathioprine and at least one of methotrexate in, and the type and dose of immunosuppressive agents should be at least stable more than 3 months. The hormone and immunosuppressant therapy scheme allows a reduction in the study period, but is not allowed to increase the volume.

-
The clinical history, signs, serological examination, HRCT and bronchoalveolar lavage results suggest that in addition to inflammatory myopathy and other diseases caused by ILD, such as CTD, systemic vasculitis, infection, tumor, allergic pneumonia caused by sarcoidosis or environmental factors.

-
Patients who were unable to understand or comply with the study procedures, including the completion of a self-administered questionnaire in the absence of help, were less likely to complete the trial.
