Brief summary
The purpose of this study is to establish an efficient and economic treatment scheme by evaluation of the safety and efficacy of subcutaneous injection of low-dose rhGM-CSF, or of similar injection after whole lung lavage , in patients with PAP.
Detailed description
The purpose of this study is to establish an efficient and economic treatment scheme by evaluation of the safety and efficacy of subcutaneous injection of low-dose rhGM-CSF, or of similar injection after whole lung lavage , in patients with PAP. During the observation, study visits will occur at the end of each month. During the 1-year follow-up period which is lasting 6 months after the treatment, all participants will be required to check the various efficacy indicators.
Interventions
GM-CSF will be given subcutaneously according to the rule in different groups.
using double lumen endotracheal tube (DLT) to selectively lavage one lung
