    Abstract Objective: Older patients with acute myeloid leukemia (AML) face a higher risk of death. This study analyzed the gene sequencing results of an elderly AML patient to provide new ideas for treatment.
    Methods: This study performed single-cell RNA sequencing (scRNA-seq) bioinformatics analysis of blood cells in the peripheral blood and bone marrow of a 64-year-old AML-M5 patient before chemotherapy. The differentially expressed genes (DEGs) were identified, and functional enrichment analyses were performed.
    Results: A total of 7990 and 123 DEGs were identified in monocytes and hematopoietic stem cells (HSCs), respectively. Among the top 40 DEGs analyzed,
    Conclusions: In conclusion, when treating elderly AML patients, it is important to consider their individual characteristics in order to optimize treatment strategies.

    Abstract Methods: Data from single-cell RNA sequencing (RNA-seq) of CLL patients were obtained from the Gene Expression Omnibus database. The R package was utilized to analyze the data, and the relation of results was predicted via the GeneMANIA website. The information of 7 samples covered three stages: observation stage, pretreatment by CIT with rituximab, fludarabine, and cyclophosphamide (pre-CIT), and post-CIT. The differentially expressed genes (DEGs) were identified, and functional enrichment analyses were performed. B cell subpopulations and pseudotime trajectories analysis was conducted.
    Results: A total of 70,659 DEGs were identified. Each patient's DEGs presented their own characteristics, with low similarity. Therefore, it is difficult to identify potential hub genes. Similarly, pathway enrichment analysis showed significant tumor heterogeneity among CLL patients. Analysis of relapsed post-CIT compared to the observation stage suggested that the
    Conclusions: Tumor heterogeneity may be a more common manifestation of CLL. Individualized treatment should be considered for CLL.

    Abstract Background: Circular RNAs (circRNAs) are frequently dysregulated in cancers and are implicated in tumorigenesis and tumor progression. In this study, we investigated the role of circZNF91 in regulating the malignant phenotype of chronic lymphocytic leukemia (CLL) cells and the underlying molecular mechanism.
    Material: /.
    Methods: The expression of circZNF91 was determined by reverse transcription-quantitative polymerase chain reaction (RT-qPCR). The binding sequences between circZNF91/miR-1283 and miR-1283/WEE1 were predicted by the bioinformatic database. The functional interactions were confirmed by the dual-luciferase reporter, RT-qPCR, and Western blot assays. The functional roles of the circZNF91/miR-1283/WEE1 axis in CLL progression were examined by cell proliferation, apoptosis, and EdU incorporation assays.
    Results: circZNF91 was upregulated in CLL samples. Silencing circZNF91 attenuated CLL cell proliferation and induced apoptosis and cell cycle arrest. circZNF91 could sponge miR-1283 to suppress its activity, which in turn upregulated WEE1 expression. Silencing circ-TTBK2 reduced WEE1 expression, while the inhibitor of miR-1283 enhanced WEE1 expression. The miR-1283/WEE1 axis mediated the effects of circZNF91 on cell proliferation and apoptosis, as well as induced cell cycle regulation.
    Conclusions: The circZNF91/miR-1283/WEE1 axis is engaged in the pathological phenotypes of CLL cells, which could serve as potential targets for future therapy development.

    Abstract Objective: To explore the clinical effects of oral small dose of cyclophosphamide (CTX) in the treatment of T-cell large granular lymphocytic leukemia (T-LGLL) accompanied with pure red cell aplasia (PRCA).
    Methods: The clinical features, characteristics of laboratory examinations and the process of oral small dose of CTX treatment after the ineffective treatment of cyclosporine A combining with prednisone in 1 case of T-LGLL with PRCA were reported and discussed with related references.
    Results: The elderly female patient had indolent process, mainly presenting with anemia and significant low hyperplasia of bone marrow erythrocyte cells. Peripheral blood smear showed mainly with characteristic large granular lymphocytic morphology. The results of immunophenotypic analyses and genetic reassortment were compatible with T-LGLL. No effects were shown after 5 months of cyclosporine A combining with prednisone treatment and the patient still needed recurrent blood transfusion. CTX was prescribed as a second-line medication and the dose was 100 mg/d. Hemoglobin could returned to normal level and the efficacy remained for 1 year even after the medication was stopped.
    Conclusion: T-LGLL accompanied with PRCA is a rare disease and oral small dose CTX can be an effective therapeutic regimen.
