Participated in clinical trials of other drugs within 4 weeks before the start of the study; 4. Patients with hypertension that cannot be well controlled by a single antihypertensive drug (systolic blood pressure > 140 mmHg, diastolic blood pressure > 90 mmHg, the specific situation is judged by the investigator), suffering from myocardial ischemia or myocardial infarction of grade I or above, arrhythmia of grade I or above (including QT interval >= 440ms), or cardiac insufficiency; 5.

History of deep vein thrombosis or pulmonary embolism within 6 months before enrollment; 17. History of autoimmune diseases (eg, Crohn's disease, rheumatoid arthritis, systemic lupus erythematosus) that lead to end-organ damage or require systemic immunosuppressive/systemic disease-modifying drugs within the past 2 years; 18. Any disease that may interfere with the evaluation of the safety or efficacy of the study treatment.
