Inclusion and exclusion criteria

Inclusion criteria：

Age between 18 and 70 years old, gender is not limited;
Lymphoma was confirmed by histopathological or cytological examination;
The patient needs to receive Selinexor combined chemotherapy containing XPO-1 inhibitor, which may include R-CHOP, R-gemox, DICE, DHAP, SMILE, etc., but is not limited to the above schemes;
Patients who do not routinely undergo preventive platelet elevation therapy after the above treatment can receive salvage therapeutic platelet elevation therapy only when the PLT is < 50×109/L;
Patients with the lowest platelet value < 50×109/L after the previous course of treatment.
The patient's laboratory examination meets the following criteria:

(1) Adequate bone marrow function at Screening: absolute count of blood neutrophils (ANC) ≥1.5×109/L; Platelet (PLT) ≥100×109/L; Hemoglobin (HB) ≥90g/L; (2) Liver function: Without liver metastasis, serum total bilirubin (TBIL) ≤ upper limit of normal (ULN) ×1.5, alanine aminotransferase (ALT), aspartate aminotransferase (AST) ≤ULN×3; With liver metastasis, TBIL≤ upper limit of normal (ULN) ×3, ALT, AST≤ULN×5; (3) Kidney function: creatinine (Cr) ≤1.5×ULN; (4) Coagulation function: International standardized ratio (INR) of prothrombin time (PT) ≤ULN×1.5;

Able to take oral medications;
Patients voluntarily sign informed consent;
Survival is expected to be ≥12 weeks at the time of screening, and can be treated with the current chemotherapy regimen for at least 2 cycles;
Subjects of reproductive age who agree to use reliable contraceptive methods throughout the study period (including male or female condoms, contraceptive foam, contraceptive gel, contraceptive film, contraceptive paste, contraceptive support, abstinence from sex, and insertion of an IUD); Excluding female subjects who have undergone hysterectomy, bilateral salpingectomy, bilateral tubal ligation, or more than 1 year postmenopausal, and male subjects who have undergone bilateral vasectomy or ligation.

Exclusion Criteria:

Thrombocytopenia caused by non-tumor chemotherapy drugs, including but not limited to hypersplenism, infection, and bleeding (including severe visceral or intracranial bleeding), occurred within 6 months before screening;
A history of blood other than lymphoma and chemotherapy-induced thrombocytopenia (CIT), such as acute lymphoblastic leukemia, acute myeloid leukemia, any myeloid malignancy, myelodysplastic syndrome, myeloproliferative diseases, and multiple myeloma;
Any history of arterial or venous thrombosis in the 3 months prior to screening;
Patients had clinical manifestations of severe bleeding (such as gastrointestinal bleeding, craniocerebral hemorrhage, etc.) 2 weeks before screening, or previous PLT > 400×109/L;
The subject has an allergic reaction to hetrombopag or any of its excipients;
Serious cardiovascular disease (such as NYHA heart function) in the 6 months prior to screening Score Ⅲ-Ⅳ), arrhythmias known to increase the risk of thromboembolism, such as atrial fibrillation, after coronary stenting, angioplasty, and coronary artery bypass grafting;
The subjects participated in other clinical studies of similar platelet enhancing drugs within 30 days prior to screening;
As assessed by the investigator, the subject has any concomitant medical history that could impair the subject's safe completion of the study, such as unstable angina pectoris, renal failure on hemodialysis, or active infection requiring intravenous antibiotics;
Subjects who are pregnant or breastfeeding, or who cannot use contraception during the trial;
Other circumstances in which the investigator considers the subject unsuitable for participation in the study;
HIV infected persons;
