The male subjects with fertility have no child rearing plan or sperm donation plan with their sexual partners during the trial and within one year after taking the drug, and could take reliable contraceptive measures. 4\. Physical examination, vital signs, laboratory (blood routine, blood biochemistry, coagulation function, urine routine, stool routine and occult blood, etc.), 12 lead ECG, chest X-ray and other tests are normal or abnormal without clinical significance. 5\. Fully understand the purpose and requirements of this trial, voluntarily participate in the clinical trial and sign the written informed consent, and can complete the whole trial process according to the test requirements.
Exclusion criteria
* 1\. Subjects with allergies or allergic diseases, or allergy to test preparations, any of their ingredients and food, or subjects with special dietary requirements, who can not follow the uniform diet. 2\. Inability to swallow oral medications or presence of diseases that affect absorption, distribution, metabolism, or excretion of study medication, as well as the evaluation of drug efficacy and safety, such as hemorrhoids or perianal diseases with regular/ongoing stool blood, habitual constipation or diarrhea, irritable bowel syndrome, inflammatory bowel disease, etc. 3\. History of gastrointestinal ulcer, bleeding, or clinically significant disease, including but not limited to circulatory, endocrine, nervous, digestive, urinary or blood, immune, mental, or metabolic diseases. 4\. Positive hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (HCV Ab), human immunodeficiency virus (HIV) or treponema pallidum antibody results within 1 month prior to dosing. 5\. Use of any drug that inhibits or induces liver drug-metabolizing enzymes (inducers-barbiturates, carbamazepine, phenytoin, rifampicin, dexamethasone, rifabutin, rifapentine, glucocorticoid, omeprazole; inhibitors-SSRI antidepressants, cimetidine, diltiazem, macrolides, verapamil, imidazole antifungals, sedatives and hypnotics, fluoroquinolones, antihistamines, etc.) within 30 days prior to dosing. 6\.
