Nerve-Derived Extracellular Matrix Promotes Neural Differentiation of Bone Marrow Stromal Cells and Enhances Interleukin-4 Efficacy for Advanced Nerve Regeneration.

Facilitating neuronal differentiation of stem cells and microenvironment remodeling are the key challenges in cell-based transplantation strategies for central nervous system regeneration. Herein, the study harnesses the intrinsic pro-neural differentiation potential of nerve-derived extracellular matrix (NDEM) and its specific affinity for cytokines to develop an NDEM-gelatin methacryloyl(gelMA)-based bifunctional hydrogel delivery system for stem cells and cytokines. This system promotes the neural differentiation of bone marrow stromal cells (BMSCs) and optimizes the therapeutic index of Interleukin-4 (IL-4) for spinal cord injury (SCI) treatment.

Shift work, thyroid function and liver function among subway workers.

Background: Shift work is associated with an increased risk of liver injury. However, whether and how shift work alters liver function remains unclear.

Aims: This study aimed to investigate the associations between shift work and the liver function parameters, and further explore the mediating roles of thyroid function indicators.

Rapid on-site determination of heavy metals and metalloids in contaminated biochar samples by accelerated leaching process coupled with voltammetric sensors.

Heavy metals and metalloids are the most common environmental pollutants. Toxicity characteristic leaching procedure (TCLP) is a standard operating procedure that is used to assess heavy metal and metalloid compositions, and evaluate the hazardous nature of waste and waste-derived materials for reuse or disposal, such as determining landfill suitability. However, TCLP and the following detections are time-consuming and require bulky laboratory-based instruments and trained personnel.

Predicting colorectal adenomatous polyps in patients with chronic liver disease: A novel nomogram.

Background: Colorectal polyps are commonly observed in patients with chronic liver disease (CLD) and pose a significant clinical concern because of their potential for malignancy.

Aim: To explore the clinical characteristics of colorectal polyps in patients with CLD, a nomogram was established to predict the presence of adenomatous polyps (AP).

Methods: Patients with CLD who underwent colonoscopy at Tianjin Second People's Hospital from January 2020 to May 2023 were evaluated.

Comparative effectiveness of acupoint stimulation for preventing postoperative nausea and vomiting after general anesthesia: A network meta-analysis of randomized trials.

Objective: To systematically evaluate the effectiveness of different acupoint stimulation techniques in preventing postoperative nausea and vomiting (PONV) after general anesthesia.

Methods: We searched PubMed, Cochrane Library, Web of Science, Embase for relevant papers, about the effect of acupoint stimulation for preventing PONV from their inception to July 31, 2023. Two reviewers performed study screening, data extraction, and risk of bias assessment.
