Drug: Azacitidine or Ruxolitinib combined with Selinexor

Interventions

Azacitidine or Ruxolitinib combined with Selinexor DRUG

1. The initial dose of Selinexor combined with Azacitidine for the treatment of MDS patients is 40mg QW, adjusted according to blood tests, with the highest dose ≤ 60mg QW. Azacitidine: The initial dose is 75 mg/m ², administered subcutaneously or intravenously, with a cycle of 1-7 days and 28 days until ineffective or intolerant. 2. Selinexor combined with Ruxolitinib for the treatment of patients with MPN symptoms: Selinexor dose: 40mg QW; Adjust according to the blood count, with a maximum dose of ≤ 60mg QW. Initial dose of Ruxolitinib: platelet count\>100 × 109/L before enrollment, initial dose is 15 mg BID; Platelets range from 50-100 × 109/L, with an initial dose of 10 mg BID. Until ineffective or intolerant.
