• 6) The subject is using immunosuppressive, or systemic, or absorbable local hormone therapy to achieve the purpose of immunosuppression (dose > 10mg/day prednisone or other equivalent hormones), and within 2 weeks before enrollment is still in use;

• 7) Ascites or pleural effusion with clinical symptoms requires therapeutic puncture or drainage;

• 8) There are clinical symptoms or diseases of the heart that cannot be well controlled, such as: (1) NYHA grade 2 or higher heart failure (2) unstable angina pectoris (3) myocardial infarction within 1 year (4) clinically significant supraventricular or ventricular arrhythmias requiring treatment or intervention;

• 9) Abnormal coagulation function (PT>16s, APTT>43s, TT>21s, Fbg>2g/L), with bleeding tendency or receiving thrombolytic or anticoagulation therapy;

• 10) The patient currently (within 3 months) has esophageal varices, active gastric and duodenal ulcers, ulcerative colitis, portal hypertension and other gastrointestinal diseases, or the unresectable tumor has active bleeding, or the investigator determines other conditions that may cause gastrointestinal bleeding and perforation;

For example, according to the researcher's judgment, the subjects have other factors that may cause the study to be terminated midway. For example, other serious diseases (including mental diseases) require concomitant treatment. Abnormal laboratory tests, accompanied by family or social factors, will affect the safety of subjects, or the collection of data and samples.
