This retrospective study analysed 106 acute myeloid leukaemia (AML) patients undergoing autologous haematopoietic stem cell transplantation (ASCT) to assess the impact of multiple small-dose infusions of granulocyte-colony-stimulating factor (G-CSF)-mobilized haploidentical lymphocytes as post-ASCT maintenance therapy. Among them, 50 patients received lymphocyte maintenance therapy, 21 received alternative maintenance therapy, and 35 received no maintenance therapy. Patients receiving lymphocyte maintenance therapy demonstrated significantly higher overall survival (OS) and disease-free survival (DFS) compared to those without maintenance therapy, with 4-year OS and DFS rates notably elevated.

However, clinical data demonstrating the effect of this combination treatment in patients with metastatic soft tissue sarcoma (STS) are currently limited. This study evaluated the safety and efficacy of a programmed cell death protein 1 (PD-1) inhibitor plus doxorubicin in patients with advanced STS who failed previous systemic therapy.

Despite continuous improvements of AML therapy, the prognosis of AML patients remains unsatisfactory. Recently, lncRNAs have been reported to participate in the development of AML. Our data demonstrated that MMP15 and LINC00963 were upregulated and miR-608 was decreased in AML cells (THP-1, HL-60, HEL and MOLM-13) compared to HS-5 cells.

PD-1-blocking therapy alone or in combination with other therapeutic modalities has become a standard treatment for several kinds of solid tumors. However, sarcomas are not indications for anti-PD-1 therapy.

Objective: To screen and identify potential biomarkers specific for T-cell acute lymphoblastic leukemia (T-ALL).

Approximately 10% of patients with polycythemia vera (PV) transform to acute leukemia (blast phase) at 10 years after initial diagnosis of PV. The bone marrow pathologic, cytogenetic, and molecular features of blast phase have not been well characterized. In this study, we reviewed 422 PV patients over a period of 11 years and identified 58 patients who developed acute myeloid leukemia (blast phase) during the course of disease.

Until now, the pathogenesis of MCL has not been fully interpreted. Our current study showed that microRNA (miR)-223 was downregulated in purified CD19 lymphocytes from MCL patients (n = 21) compared with that of healthy donors (n = 20).

The present study describes a case of AML plus maturation (-M2) with multilineage dyspoiesis in a 30-year-old male in whom a 46,XY,t(7;11)(p15;p15) karyotype was detected through chromosome analysis. Subsequent molecular and sequencing analysis demonstrated a fusion gene with a type I fusion between exon 12 and exon 1b, and mutations in neuroblastoma V-Ras oncogene homolog and Wilms tumor 1.

However, the cytogenetic abnormalities in polycythemia vera have not been well characterized and their prognostic impact is largely unknown. In this study, we aimed to address these issues using a large cohort of polycythemia vera patients with cytogenetic information available.

Aims: Chromosome 11q23 translocations, resulting in ) rearrangement, have been well characterised in acute myeloid leukaemia (AML) and acute lymphoblastic leukaemia (ALL). However, little is known of haematopoietic neoplasms associated with 11q23 translocation but without rearrangement (11q23+/-). The aim of this study is to characterise such cases with 11q23+/-.

It has been suggested that omacetaxine mepesuccinate, used alone or with interferon‑α or cytarabine, induces remission in patients with chronic myelogenous leukemia. These effects are possibly mediated by its ability to induce apoptosis of leukemia cells and inhibit the activity of telomerase.

Herein, we synthesized CeVO4 nanocrystals with hexagonal nanoplate structures from the reaction of decavanadate (K6V10O28⋅9 H2O) and CeCl3⋅H2O precursors via a hydrothermal method. This synthetic route has four advantages: 1) the reaction condition is relatively mild, 2) it doesn't need surfactants or templates, 3) it requires no expensive equipment, and 4) products are of higher purity.

After coating them on silica gel, their chiral recognition abilities were evaluated as the chiral stationary phases (CSPs) for high-performance liquid chromatography. These coated-type CSPs exhibited different chiral recognitions depending on the position, nature, and number of the substituents introduced on the phenyl group, and the introduction of either an electron-withdrawing or an electron-donating substituent improved the chiral recognition of the CSPs.

A new ethylenediaminetetraacetic acid- (EDTA-) mediated hydrothermal route to prepare chrysanthemum-shaped samarium orthovanadate (SmVO₄) nanocrystals with decavanadate (K₆V₁₀O₂₈·9H₂O) as vanadium source has been developed. The present hydrothermal approach is simple and reproducible and employs a relatively mild reaction temperature. The EDTA, pH value, and temperature of the reaction systems play important roles in determining the morphologies and growth process of the SmVO₄ products.

Objective: To investigate the effectiveness of testicular sperm cryopreservation in male fertility preservation by evaluating the clinical outcome of ICSI cycles with frozen-thawed testicular sperm for azoospermia patients.
Methods: We retrospectively analyzed 96 samples of cryopreserved testicular sperm obtained by testicular biopsy, vasovasostomy (V-V), vasoepididymostomy (V-E) , of which 55 were subjected to 60 ICSI cycles with frozen-thawed testicular sperm. We evaluated the rates of sperm recovery, fertilization, cleavage, transferable and good-quality embryos, clinical pregnancy, pregnancy outcome, and health of the newborns.
