Thickening of the cervical ligamentum flavum (CLF) has been considered as a main cause of cervical spinal stenosis (CSS). A previous study reported that cervical ligamentum flavum thickness (CLFT) is correlated with CSS. However, the whole hypertrophy is different from focal thickness. ⋯ The optimal cut off-point of the CLFT was 1.79 mm, with a sensitivity of 83.5%, specificity of 84.5%, and an area under the curve of 0.92 (95% CI, 0.87-0.96). Both CLFT and CLFA were significantly related to CSS, but CLFA was the more sensitive measurement parameter. Therefore, to evaluate patients with CSS, treating physicians should test for CLFA.

To investigate the efficacy of a nursing approach using B-cell maturation antigen (BCMA)-targeted universal chimeric antigen receptor T-cell (BCMA-UCART) immunotherapy in the treatment of 8 patients with relapsed refractory multiple myeloma (MM). In this study, 16 patients with relapsed and refractory MM who were treated with BCMA-targeted UCART in our department from May 2020 to November 2022 were selected, and were divided into a control group and an experimental group of 8 cases each according to the difference in the nursing methods, and the control group adopted the conventional universal nursing program. The experimental group used the nursing protocol that cooperated with the immunotherapy of this study, and the main points of nursing care included timely assessment of organ functional status, safe and accurate infusion of BCMA-UCART, identification and management of hyperthermia, hypotension, arrhythmia and central nervous system adverse reactions caused by cytokine release after BCMA-UCART infusion, as well as management of fluid imbalance, maintenance of stable blood pressure, and cooperation with physicians to effectively control of inflammatory factors. ⋯ The duration of hospitalization was compared between the two groups after the intervention. The discharge time of the experimental group was significantly shorter than that of the control group (P he.05), and the experimental group effectively controlled cytokine release syndrome, immune effector cell-associated neurotoxicity syndrome and acute graft-versus-host disease. The nursing program with BCMA-UCART immunotherapy is effective in intervening MM patients and promotes their early recovery and discharge from the hospital.

This study aims to identify common molecular biomarkers between amyotrophic lateral sclerosis (ALS) and depression using bioinformatics methods, in order to provide potential targets and new ideas and methods for the diagnosis and treatment of these diseases. Microarray datasets GSE139384, GSE35978 and GSE87610 were obtained from the Gene Expression Omnibus (GEO) database, and differentially expressed genes (DEGs) between ALS and depression were identified. After screening for overlapping DEGs, gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed. ⋯ Five possible target miRNAs, including miR-221-5p, miR-21-5p, miR-100-5p, miR-30b-5p, and miR-615-3p, were predicted by constructing a miRNA-gene network. This study used bioinformatics techniques to explore the potential association between ALS and depression, and identified potential biomarkers. These biomarkers may provide new ideas and methods for the early diagnosis, treatment, and monitoring of ALS and depression.

As individuals age, cancer becomes increasingly common. This continually rising risk can be attributed to various interconnected factors that influence the body's susceptibility to cancer. Among these factors, the accumulation of senescent cells in tissues and the subsequent decline in immune cell function and proliferative potential are collectively referred to as immunosenescence. ⋯ Furthermore, there are several age-related intervention methods, including metformin and rapamycin, which involve genetic and pharmaceutical approaches. This article aims to elucidate the defining characteristics of immunosenescence and its impact on malignant tumors and immunotherapy. We particularly focus on the future directions of cancer treatment, exploring the complex interplay between immunosenescence, cancer, and potential interventions.

To introduce a novel transverse connecting screw system, and to evaluate the biomechanical stability of the novel screw system using human cadaveric specimens. ⋯ The APTCS system was able to restore stability to the atlantoaxial joint. APTCS system has the advantages of easy installation, convenient bone grafting, and strong biomechanical strength.
