•Use of prohibited drugs specified in the protocol within 14 days before enrollment;
•The mean oxygen saturation \< 85% or the lowest oxygen saturation \< 70% by PSG.
•Acute or chronic diseases affecting efficacy evaluation, such as severe chronic obstructive pulmonary disease (COPD);
•Previous history of drug, alcohol, narcotic or other drug abuse or dependence;
•Any serious cardiovascular system abnormalities (e.g., ischemic cardio-cerebral disease), such as recent myocardial infarction, angina, severe hypertension or arrhythmia in the recent 6 months, ECG Fridericia-corrected QT interval higher than 450 ms, history of left ventricular hypertrophy or mitral valve prolapse;
•Subjects with severe co-morbid medical or biological conditions that may jeopardize participation in the study (especially cardiovascular system problems and unstable diabetes) as judged by the investigator;
