Primary Outcome Measures:

Improvements in double pulmonary diffuse lesions （Chest CT score ） [ Time Frame: 6 months ]

Secondary Outcome Measures:

Clinical symptoms observation: shod of breath, cough (according to each score standard） [ Time Frame: 6 months ]
Granulocyte Macrophage Colony Stimulating Factor(GM-CSF) Antibody titer change [ Time Frame: 6 months ]
Improvements in pulmonary function [ Time Frame: 6 months ]
Pulmonary function tests include residual volume/total lung capacity(RV/TLC), forced vital capacity(FVC), forced expiratory volume in one second/forced vital capacity(FEV1/FVC), diffusing capacity of carbon monoxide(DLCO).
Improvements in arterial blood gas, including alveolar-arterial oxygen difference(A-aDO2), partial pressure of oxygen(PaO2), partial pressure of carbon dioxide in artery(PaCO2), arterial oxygen saturation(SaO2). [ Time Frame: 6 months ]

Arms	Assigned Interventions
Experimental: D1 Patients diagnosed with PAP will be received rhGM-CSF 1.25 ug/kg/d subcutaneously for 1 month, before evaluation on the 30th day (±3 day). If the treatment is effective, participants may be entered into low-dose group(D1)(rhGM-CSF administration 1.25 ug/kg/d, qd, sc, for 2 months，then rhGM-CSF administration 1.25 ug/kg/d, qod, sc, for 3 months), when the chest CT absorption≥25% , and /or the PaO2 elevated by 5 mm Hg.	Drug: rhGM-CSF GM-CSF will be given subcutaneously according to the rule in different groups. Other Names: TOPLEUCON GM-CSF Recombinant Granulocyte Macrophage-Colony Stimulating Factor Granulocyte Macrophage-Colony Stimulating Factor
Experimental: D2 Patients diagnosed with PAP will be received rhGM-CSF 1.25 ug/kg/d subcutaneously for 1 month, before evaluation on the 30th day (±3 day). When the treatment is ineffective, and anti-GM-CSF antibody titers level ≥1:1000，the dose will be increased to 2.5 ug/kg/d. After 2 months, if the clinical response was optimal, that dose is continued for 3 months, and defined as group 2(D2).	Drug: rhGM-CSF GM-CSF will be given subcutaneously according to the rule in different groups. Other Names: TOPLEUCON GM-CSF Recombinant Granulocyte Macrophage-Colony Stimulating Factor Granulocyte Macrophage-Colony Stimulating Factor
Experimental: D3 Patients diagnosed with PAP will be received rhGM-CSF 1.25 ug/kg/d subcutaneously for 1 month, before evaluation on the 30th day (±3 day). When the treatment is ineffective, and anti-GM-CSF antibody titers level ≥1:1000，the dose will be increased to 2.5 ug/kg/d. After 2 months, if the clinical response was not optimal, the patients will receive whole lung lavage(WLL), who are defined as group 3(D3).	Drug: rhGM-CSF GM-CSF will be given subcutaneously according to the rule in different groups. Other Names: TOPLEUCON GM-CSF Recombinant Granulocyte Macrophage-Colony Stimulating Factor Granulocyte Macrophage-Colony Stimulating Factor
Active Comparator: D4 Patients diagnosed with PAP will be received rhGM-CSF 1.25 ug/kg/d subcutaneously for 1 month, before evaluation on the 30th day (±3 day). When the treatment is ineffective, and anti-GM-CSF antibody titers level ＜1:1000，the patients will receive whole lung lavage(WLL), then give rhGM-CSF administration (1.25 ug/kg/d) for 3 months, which belong to group4(D4).	Drug: rhGM-CSF GM-CSF will be given subcutaneously according to the rule in different groups. Other Names: TOPLEUCON GM-CSF Recombinant Granulocyte Macrophage-Colony Stimulating Factor Granulocyte Macrophage-Colony Stimulating Factor Procedure: Whole Lung Lavage(WLL) using double lumen endotracheal tube (DLT) to selectively lavage one lung Other Names: Whole Lung Lavage WLL

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.
