8. Recent major changes in diet or exercise habits;
9. Use of an investigational drug or product, or participation in a drug research study within 30 days (or 5 half-lives) prior to receiving study drug;
10. History of difficulties in swallowing, or any gastrointestinal disease which could affect the drug absorption;
11. Suffering from any diseases that may increase the risk of bleeding, such as hemorrhoids, acute gastritis, stomach and duodenal ulcers, Thrombocytopenic Purpura and hemophilia, etc;
