Biomechanical analysis of adjacent segments after correction surgery for adult idiopathic scoliosis: a finite element analysis.

The biomechanical aspects of adjacent segment degeneration after Adult Idiopathic Scoliosis (AdIS) corrective surgery involving postoperative changes in motion and stress of adjacent segments have yet to be investigated. The objective of this study was to evaluate the biomechanical effects of corrective surgery on adjacent segments in adult idiopathic scoliosis by finite element analysis. Based on computed tomography data of the consecutive spine from T1-S1 of a 28-year-old male patient with adult idiopathic scoliosis, a three-dimensional finite element model was established to simulate the biomechanics.

Thrombopoietin receptor agonists use and risk of thrombotic events in patients with immune thrombocytopenic purpura: A systematic review and meta‑analysis of randomized controlled trials.

Thrombopoietin receptor agonists (TPO-RAs) have a role in second-line immune thrombocytopenic purpura (ITP) treatment, binding to and activating thrombopoietin receptors on megakaryocyte membranes in the bone marrow. This promotes megakaryocyte maturation and increases platelet production. Despite a 2-6% incidence of thrombotic events during TPO-RA treatment, it remains uncertain whether TPO-RAs elevate thrombosis rates.

Association of High Plasma Levels of Serpin E1, IGFBP2, and CCL5 With Refractory Epilepsy in Children by Cytokine Profiling.

Inflammatory cytokines participate in the pathology of epilepsy and the development of drug resistance. In this study, we combined a cytokine array and enzyme-linked immunosorbent assay to identify new cytokines in the plasma from children on early stage of the onset of epilepsy (EOE) and children with drug-resistant epilepsy (DRE). Compared with healthy controls, a broad up-regulation of cytokines was observed in patients with EOE, and many of the cytokines were not previously reported.

Up-regulation of PRKDC was associated with poor renal dysfunction after renal transplantation: A multi-centre analysis.

Renal transplantation is the only efficacious treatment for end-stage kidney disease. However, some people have developed renal insufficiency after transplantation, the mechanisms of which have not been well clarified. Previous studies have focused on patient factors, while the effect of gene expression in the donor kidney on post-transplant renal function has been less studied.

A novel RIPK1 inhibitor reduces GVHD in mice via a nonimmunosuppressive mechanism that restores intestinal homeostasis.

Intestinal epithelial cells (IECs) are implicated in the propagation of T-cell-mediated inflammatory diseases, including graft-versus-host disease (GVHD), but the underlying mechanism remains poorly defined. Here, we report that IECs require receptor-interacting protein kinase-3 (RIPK3) to drive both gastrointestinal (GI) tract and systemic GVHD after allogeneic hematopoietic stem cell transplantation. Selectively inhibiting RIPK3 in IECs markedly reduces GVHD in murine intestine and liver.

CircRNAs in Malignant Tumor Radiation: The New Frontier as Radiotherapy Biomarkers.

World Health Organization (WHO) data show that of the top 20 factors that threaten human life and health, cancer is at the forefront, and the therapeutic approaches for cancer consist of surgery, radiotherapy, chemotherapy and immunotherapy. For most highly metastatic and recurrent cancer, radiation therapy is an essential modality to mitigate tumor burden and improve patient survival. Despite the great accomplishments that have been made in clinical therapy, an inevitable challenge in effective treatment is radioresistance, the mechanisms of which have not yet been completely elucidated.

Comparative efficacy of 19 drug therapies for patients with idiopathic thrombocytopenic purpura: a multiple-treatments network meta-analysis.

Immune thrombocytopenia (ITP) is the most common clinical bleeding disorder with a high mortality rate and poor long-term survival quality in severe patients. There is controversy on how to choose the appropriate treatment. We systematically reviewed 19 randomized controlled trials (including 2615 participants) from January 1, 2015, to April 20, 2021.

HUWE1 Causes an Immune Imbalance in Immune Thrombocytopenic Purpura by Reducing the Number and Function of Treg Cells Through the Ubiquitination Degradation of Ets-1.

Immune thrombocytopenic purpura (ITP) is an autoimmune bleeding disorder and the decreased number and immunosuppressive dysfunction of Treg cells are key promoters of ITP. However, their mechanisms in ITP development have not been fully clarified. HUWE1 mRNA and protein levels in CD4 T cells in peripheral blood from ITP patients were assessed by quantitative real-time PCR and Western blot.

The clinical outcomes and genomic landscapes of acute lymphoblastic leukemia patients with E2A-PBX1: A 10-year retrospective study.

The clinical outcomes and genomic features of E2A-PBX1 (TCF3-PBX1)-positive B-cell acute lymphoblastic leukemia (B-ALL) patients remain unclear. A total of 137 patients carrying E2A-PBX1 among 3164 B-ALL patients between 2009 and 2019 were retrospectively analyzed. The 5-year overall survival (OS) and disease-free survival (DFS) rates of the whole cohort were 68.

MAFG-driven osteosarcoma cell progression is inhibited by a novel miRNA miR-4660.

Osteosarcoma (OS) is the most common primary bone malignancy in the adolescent population. MAFG (v-maf avian musculoaponeurotic fibrosarcoma oncogene homolog G) forms a heterodimer with Nrf2 (NF-E2-related factor 2), binding to antioxidant response element (ARE), which is required for Nrf2 signaling activation. We found that mRNA and protein expression is significantly elevated in human OS tissues as well as in established and primary human OS cells.

Extracellular vesicles derived from miR-199a-5p-modified adipose-derived mesenchymal stem cells alleviate immune thrombocytopenia by inhibiting T helper 17 differentiation.

The abnormal differentiation of T helper 17 (Th17) cells is considered a vital promoter of immune thrombocytopenia (ITP) progression. Therefore, this study investigated the role of miR-199a-5p in Th17 differentiation and determined whether extracellular vesicles (EVs) derived from miR-199a-5p-modified adipose-derived mesenchymal stem cells (ADSCs) could relieve ITP by inhibiting Th17 differentiation. The miR-199a-5p level was lessened in the spleen tissues of mice with ITP, while the signal transducer and activator of transcription 3 (STAT3) expression and the population of Th17 in CD4T cells were boosted.
