interstitial pulmonary disease;
6. Abnormal coagulation function (INR>1.5 or prothrombin time (PT)>ULN+4 seconds or
APTT>1.5 ULN), have a bleeding tendency or are receiving thrombolytic or anticoagulant
therapy;
7. The daily volume of hemoptysis reached two teaspoons or more before enrollment;
8. Patients who have had clinically significant bleeding symptoms or a clear bleeding
tendency within 3 months before enrollment, such as gastrointestinal bleeding,
hemorrhagic hemorrhoids, hemorrhagic gastric ulcer, fecal occult blood++ and above at
baseline, or vascular
9. Arterial/venous thrombosis events that occurred in the 12 months before enrollment,
such as cerebrovascular accidents (including temporary ischemic attacks, cerebral
hemorrhage, cerebral infarction), deep vein thrombosis, and pulmonary embolism;
10. Known existing hereditary or acquired bleeding and thrombotic tendency (such as
hemophilia, blood coagulation dysfunction, thrombocytopenia, hypersplenism, etc.);

not counted);
12. Patients who received major surgery or suffered severe traumatic injury, fracture, or
ulcer within 4 weeks of enrollment;
13. some factors significantly affect the absorption of oral drugs, such as inability to
swallow, chronic diarrhea, and intestinal obstruction;

drugs cannot be used for the treatment of serious effusions), and patients who are
judged by the investigator can be included in the group,allow to join the group.
