Guidelines of the National Scientific Society of Infectious Diseases Specialists,

6. Participation in other clinical studies within three months before screening;

7. Chronic respiratory system diseases (asthma, COPD);

8. Administration of neuraminidase inhibitors (zanamivir, oseltamivir), immunomodulators,
systemic glucocorticoids, and antibiotics within one month before screening;

pulmonary embolism or deep vein thrombosis;

11. Chronic alcohol abuse, drug abuse or addiction to the other chemicals in history;

12. Inability to read or write; unwillingness to understand and comply with the Protocol
procedures; non-compliance with the drug dosing regimen or procedures which, in the
