Inclusion Criteria

1. Volunteer to participate in clinical research and sign informed consent;
2. Age ≥18 years;
3. Digestive system malignancy confirmed by histology or cytology; Having used oxaliplatin combined with fluorouracil for at least one cycle of 21-day chemotherapy regimen (CAPOX or SOX regimen), platelet index after chemotherapy: ≥25×109/L and ≤75×109/L;

8. Women of reproductive age must be willing to use adequate contraception during the study of drug treatment.

Exclusion Criteria

1. Thrombocytopenia caused by non-tumor chemotherapy drugs occurred within 6 months before screening, including but not limited to EDTA-dependent pseudothrombocytopenia, hypersplenism, infection, and bleeding;
2. Have any hematological malignancies, including leukemia, myeloma, bone marrow proliferative diseases, lymphoma or bone marrow proliferative diseases;
3. Clinically significant acute or active bleeding within the week prior to screening;
4. Subject has medically known hereditary prethrombotic syndrome (e.g., factor V Leiden mutation, prothrombin G20210A mutation, or hereditary antithrombin III (ATIII) deficiency)
5. The subject has a history of major cardiovascular disease (e.g., congestive heart failure (New York Heart Association Class 3/ cardiac function), known arrhythmias (e.g., atrial fibrillation) that increase the risk of thromboembolic events, coronary stenting, angioplasty, or coronary artery bypass grafting);
6. Subjects had a history of arterial or venous thrombosis within 3 months before screening;
7. Use of a vitamin K antagonist (including low molecular weight heparin, factor Xa inhibitor, or thrombin inhibitor) within 7 days prior to screening;
8. The subject has a history of chronic platelet or hemorrhagic disorders, or thrombocytopenia from causes other than CIT (e.g., chronic liver disease or immune thrombocytopenic purpura);
9. TPO, IL-11 or platelet infusion were used within 10 days before enrollment;
10. Previous use of thrombopoietin receptor agonists (e.g., eltrobopag, romiestine, etc.)
11. Those who cannot be treated with oral drugs;
12. Allergic to hetrombopag or any excipient;
13. Those whose organ function could not tolerate further antitumor therapy as assessed by the investigator; This product is not recommended for use or discontinuation of treatment in patients who meet any of the following criteria for liver function

ALT and AST > 8 x ULN.

ALT or AST>5×ULN for 2 weeks;

ALT or AST>3xULN (total bilirubin >2xULN or INR>1.5);

ALT or AST>3×ULN with progressive fatigue, nausea, vomiting, right upper abdominal pain or tenderness, fever, rash, and/or eosinophilia (>5%).
