Efficacy and safety of hetrombopag in the treatment of recombinant human thrombopoietin-resistant thrombocytopenia after allogeneic hematopoietic stem cell transplantation.

Background: Thrombocytopenia after allogeneic hematopoietic cell transplantation is a challenging clinical problem. Recombinant human thrombopoietin (rhTPO) and thrombopoietin receptor agonists are increasingly used in posttransplant thrombocytopenia. However, the use of hetrombopag in patients with posttransplant thrombocytopenia, especially in patients with resistance to rhTPO, has not yet been reported.

[Effect of rhTPO and rhIL-11 on Thrombocytopenia after Chemotherapy in Leukemia].

Objective: To analyze and compare the efficacy of recombinant human thrombopoietin (rhTPO) and recombinant human interleukin-11 (rhIL-11) in the treatment of thrombocytopenia after chemotherapy in acute leukemia patients.

Methods: 180 patients with acute leukemia complicated with thrombocytopenia after chemotherapy in the First Affiliated Hospital of Anhui Medical University were analyzed retrospectively. Among them, 50 patients who treated with rhTPO and did not receive platelet transfusion were set as group A, 50 patients treated with rhTPO and receive platelet transfusion were set as group B, Forty patients treated with rhIL-11 without platelet transfusion were set as group C, Forty patients who treated with rhIL-11 and received platelet transfusion were set as group D.

TIM-3 Expression Level on AML Blasts Correlates With Presence of Core Binding Factor Translocations Rather Than Clinical Outcomes.

Background: T-cell immunoglobulin and mucin domain-containing molecule 3 (TIM-3) expresses on leukemic stem and progenitor populations of non-M3 acute myeloid leukemia (AML) as well as T lymphocytes. TIM-3 is thought to be involved in the self-renewal of leukemic stem cells and the immune escape of AML cells, however its correlation with AML prognosis is still controversial and worthy of further investigation.

Methods: we simultaneously assessed TIM-3 expression levels of leukemic blasts and T lymphocytes in the bone marrow of AML patients using flow cytometry.

[Identification of Volatile Organic Compounds Used to Diagnose and Evaluate Acute Promyelocyte Leukemia].

Objective: To analyze the characteristics of volatile organic compounds (VOCs) in expiratory air components of patients with acute promyelocytic leukemia (APL), and assess the feasibility of VOCs for the diagnosis and prognostic evaluation of APL.

Methods: The VOCs exhaled from the patients with APL and healthy volunteers should be analyzed with SPME-GC/MS, and compared between newly-diagnosed group, relapse group, remission group, and healthy group with Wilcoxon/Kruskal-Wallis one-way analysis of variance and Dunn-Bonferroni test.

Results: Dimethyl sulfide, toluene, and dodecane obtained of newly-diagnosed APL patients were significantly higher, while ethanol, n-hexanal, and benzaldehyde were significantly lower than those of healthy people (P<0.
