Gastric cancer prevention by community eradication of Helicobacter pylori: a cluster-randomized controlled trial.

Gastric cancer is a leading cause of cancer-related deaths in China. Affecting more than 40% of the world's population, Helicobacter pylori is a major risk factor for gastric cancer. While previous clinical trials indicated that eradication of H.

Metronomic capecitabine inhibits liver transplant rejection in rats by triggering recipients' T cell ferroptosis.

Background: Capecitabine (CAP) is a classic antimetabolic drug and has shown potential antirejection effects after liver transplantation (LT) in clinical studies. Our previous study showed that metronomic CAP can cause the programmed death of T cells by inducing oxidative stress in healthy mice. Ferroptosis, a newly defined non-apoptotic cell death that occurs in response to iron overload and lethal levels of lipid peroxidation, is an important mechanism by which CAP induces cell death.

Beneficial effects of endoscopic screening on gastric cancer and optimal screening interval: a population-based study.

BACKGROUND : The effectiveness of endoscopic screening on gastric cancer has not been widely investigated in China and the screening interval of repeated screening has not been determined. METHODS : In a population-based prospective study, we included 375,800 individuals, 14,670 of whom underwent endoscopic screening (2012-2018). We assessed the associations between endoscopic screening and risk of incident gastric cancer and gastric cancer-specific mortality, and examined changes in overall survival and disease-specific survival following screening.

Tumor Cell-Derived Exosomal Circ-0072088 Suppresses Migration and Invasion of Hepatic Carcinoma Cells Through Regulating MMP-16.

Tumor-derived exosomes (EXOs), commonly differentially expressed in circular RNAs, have been shown to be crucial determinants of tumor progression and may regulate the development and metastasis of hepatic carcinoma (HCC). Possibly differentially expressed circRNAs in patients with HCC were screened out from the Gene Expression Omnibus (GEO). EXOs were isolated from the culture medium of HCC cells and plasma of patients with HCC, followed by characterization by transmission electron microscope, NanHCCight, and western blotting.

Thoracic de-kyphosis for revision surgery of a failure case of endoscopic discectomy: a case report and literature review.

Background: Indications and clinical outcomes of percutaneous endoscopic thoracic discectomy(PETD) in treating thoracic disc herniation is rarely reported and still controversial. We reported an unsatisfied recovery of thoracic disc herniation with PETD, treated by a second posterior thoracic laminectomy and Ponte osteotomy.

Case Description: A male presented with lower extremity weakness and stagger caused by T3/4 intervertebral disc herniation.

Percutaneous Endoscopic Lumbar Discectomy in Treating Calcified Lumbar Intervertebral Disc Herniation.

Background: We retrospectively analyzed and report the clinical results of percutaneous endoscopic lumbar discectomy (PELD) in treating patients with calcified lumbar intervertebral disc herniation (CLDH).

Methods: The data from 40 patients with CLDH treated with PELD in our hospital from June 2013 to June 2017 were reviewed. Of the 40 patients, 27 (19 men; 8 women; average age, 45.

Tantalum-coated pedicle screws enhance implant integration.

Because titanium alloy (Ti) has the natural advantage of a low elastic modulus, it has become the most commonly used material for the manufacturing of pedicle screws. However, its poor shear strength and osteogenic ability are undesirable properties. The superior osteoinductivity demonstrated by tantalum (Ta) in oral and maxillofacial surgery and joint surgery leads us to assume that the tantalum-coated pedicle screws may have better osteogenic properties and bone anchoring strength.

Cut-off optimization for C-urea breath test in a community-based trial by mathematic, histology and serology approach.

The performance of diagnostic tests in intervention trials of Helicobacter pylori (H.pylori) eradication is crucial, since even minor inaccuracies can have major impact. To determine the cut-off point for C-urea breath test (C-UBT) and to assess if it can be further optimized by serologic testing, mathematic modeling, histopathology and serologic validation were applied.

Human VE-Cadherin Fusion Protein as an Artificial Extracellular Matrix Enhancing the Proliferation and Differentiation Functions of Endothelial Cell.

In an attempt to enhance endothelial cell capture and promote the vascularization of engineered tissue, we biosynthesized and characterized the recombinant fusion protein consisting of human vascular endothelial-cadherin extracellular domain and immunoglobulin IgG Fc region (hVE-cad-Fc) to serve as a bioartificial extracellular matrix. The hVE-cad-Fc protein naturally formed homodimers and was used to construct hVE-cad-Fc matrix by stably adsorbing on polystyrene plates. Atomic force microscop assay showed uniform hVE-cad-Fc distribution with nanorod topography.

Neck motion following multilevel anterior cervical fusion: comparison of short-term and midterm results.

Object: Multilevel anterior cervical decompression and fusion is indicated for patients with multilevel compression or stenosis of the spinal cord. Some have reported that this procedure would lead to a loss of cervical range of motion (CROM). However, few studies have demonstrated the exact impact of the procedure on CROM.
