Implementation and Evaluation of Discharge Planning for Patients Undergoing Umbilical Cord Blood Transplantation.

BACKGROUND Umbilical cord blood transplantation (UCBT) patients have high rates of unplanned readmissions and poor quality of life (QoL). The aim of this study was to evaluate the effects of discharge planning on unplanned readmissions, self-efficacy, QoL, and clinical outcomes. MATERIAL AND METHODS Patients who received their first UCBT from April 2022 to March 2023 were included.

LukS-PV Induces Apoptosis the SET8-H4K20me1-PIK3CB Axis in Human Acute Myeloid Leukemia Cells.

Evidence suggests that histone modification disorders are involved in leukemia pathogenesis. We previously reported that LukS-PV, a component of Panton-Valentine leukocidin (PVL), has antileukemia activities that can induce differentiation, increase apoptosis, and inhibit proliferation of acute myeloid leukemia (AML) cells. Furthermore, LukS-PV inhibited hepatoma progression by regulating histone deacetylation, speculating that LukS-PV may exert antileukemia activity by targeting histone modification regulators.

Effects and long-term follow-up of using umbilical cord blood-derived mesenchymal stromal cells in pediatric patients with severe BK virus-associated late-onset hemorrhagic cystitis after unrelated cord blood transplantation.

This is a retrospective study to evaluate the efficacy and safety of umbilical cord blood-derived mesenchymal stromal cells (MSCs) for the treatment of pediatric patients with severe BK virus-associated late-onset hemorrhagic cystitis (BKV-HC) after unrelated cord blood transplantation (UCBT). Thirteen pediatric patients with severe BKV-HC from December 2013 to December 2015 were treated with MSCs. The number of MSCs transfused in each session was 1 × 10 /kg once a week until the symptoms improved.

[Efficacy Analysis of Unrelated Cord Blood Transplantation for High-Risk Refractory AML1-ETO Positive Myeloid Leukemia].

Objective: To analyze the clinical outcomes of engraftment, graft-versus-host disease (GVHD) and survival in the patients with AML1-ETO positive acute myeloid leukemia (AML) treated with unrelated umbilical cord blood transplantation (UCBT).

Methods: Forty-Five patients with high-risk refractory AML1-ETO positive AML were treated with a single UCBT in a single center from July 2010 to April 2018. All the patients underwent a myeloablative preconditioning regimen，and cyclosporine A (CSA) combined with mycophenolate mofetil (MMF) was used to prevent GVHD.

[Effects of HMGB1 on human cord blood CD34(+) hematopoietic stem cells proliferation and differentiation in vitro.].

Objective: To study both the release of HMGB1 from irradiation-treated mesenchymal stem cells (MSCs) and the effects of HMGB1 on human cord blood CD34(+) hematopoietic progenitor cell proliferation and differentiation.

Methods: MSCs were obtained from human bone marrow. HMGB1 released by the MSCs after treatment with 12 Gy gamma-ray irradiation was determined by enzyme linked immunosorbent assay (ELISA).

[Influence of high mobility group box 1 on migration of human cord blood CD34(+) cells].

The objective of study was to explore the influence of high mobility group box 1 (HMGB1) on migration of cord blood CD34(+) cells and their mechanism of migration. The expressions of receptor for advanced glycation end products (RAGE), toll-like receptor-2 (TLR2) and TLR4 were detected by flow cytometry. The CD34(+) cells in umbilical cord blood (CB) were enriched by MiniMACS and were exposed to various concentration of HMGB1 (10, 50, 100, 1, 000 ng/ml), then the migration effect of HMGB1 on umbilical cord blood (UCB) CD34(+) cell count was determined by microscopy, the chemotactic index was calculated.
