Background: The relationship between autoimmune gastritis (AIG) and gastric polyps (GPs) is not well understood.

Aim: To explore the clinical characteristics and risk factors of AIG with GPs in patients.

Methods: This double center retrospective study included 530 patients diagnosed with AIG from July 2019 to July 2023.

Neuropilin-1-Targeted Nanomedicine for Spatiotemporal Tumor Suppression through Photodynamic Vascular Damage and Antiangiogenesis.

Antiangiogenic therapy is an effective way to disrupt nutrient supply and starve tumors, but it is restricted by poor efficacy and negative feedback-induced tumor relapse. In this study, a neuropilin-1 (NRP-1)-targeted nanomedicine (designated as FPPT@Axi) is reported for spatiotemporal tumor suppression by combining photodynamic therapy (PDT) with antiangiogenesis. In brief, FPPT@Axi is prepared by utilizing an NRP-1-targeting chimeric peptide (Fmoc-K(PpIX)-PEG-TKPRR) to encapsulate the antiangiogenic drug Axitinib (Axi).

ISRIB inhibits the senescence of type II pulmonary epithelial cells to alleviate pulmonary fibrosis induced by silica in mice.

The role and mechanisms of integrated stress response inhibitor (ISRIB) on silicosis are still not well defined. In the present study, the effects of ISRIB on cellular senescence and pulmonary fibrosis in silicosis were evaluated by RNA sequencing, micro-computed tomography, pulmonary function assessment, histological examination, and Western blot analysis. The results showed that ISRIB significantly reduced the degree of pulmonary fibrosis in mice with silicosis and reduced the expression of type I collagen, fibronectin, α-smooth muscle actin, and transforming growth factor-β1.

Optimization of endometrial cancer organoids establishment by cancer-associated fibroblasts.

Most endometrial cancers (EC) are diagnosed at an early stage with a favorable prognosis. However, for patients with advanced or recurrent disease, the chemotherapy response rate and overall survival remain poor. A novel in vitro model, tumor organoids, has important value in providing a more individualized treatment plan for tumor patients.

OC-STAMP Overexpression Drives Lung Alveolar Epithelial Cell Type II Senescence in Silicosis.

Cellular senescence has been considered an important driver of many chronic lung diseases. However, the specific mechanism of cellular senescence in silicosis is still unknown. In the present study, silicotic rats and osteoclast stimulatory transmembrane protein () overexpression of MLE-12 cells were used to explore the mechanism of OC-STAMP in cellular senescence in alveolar epithelial cell type II (AEC2).

Long noncoding RNA MRCCAT1 promotes metastasis of clear cell renal cell carcinoma via inhibiting NPR3 and activating p38-MAPK signaling.

Background: Recent evidences showed that long noncoding RNAs (lncRNAs) are frequently dysregulated and play important roles in various cancers. Clear cell renal cell carcinoma (ccRCC) is one of the leading cause of cancer-related death, largely due to the metastasis of ccRCC. However, the clinical significances and roles of lncRNAs in metastatic ccRCC are still unknown.

Dishevelled2 promotes apoptosis and inhibits inflammatory cytokine secretion in rheumatoid arthritis fibroblast-like synoviocytes through crosstalk with the NF-κB pathway.

Dishevelled (Dvl) not only links the canonical Wnt and non-canonical Wnt pathways but can also crosstalk with other pathways. As there is no systematic study to date on Dvl in rheumatoid arthritis (RA), we explored the impact of Dvl2 on proliferation and inflammatory cytokine secretion in RA fibroblast-like synoviocytes (FLSs). Expression of Dvl2 in RA synovial tissue and RA-FLSs was measured.

Prospective study of the safety and efficacy of a pancreatic cancer stem cell vaccine.

Introduction: In this trial, we isolated and cultured pancreatic cancer stem cells (CSCs) to produce a vaccine and prospectively evaluated its safety and efficacy in low-, medium-, and high-dose groups.

Material And Methods: Between February and October 2014, we enrolled 90 patients who met the enrollment criteria and assigned them to three groups (n = 30). CSC-specific and CSC-non-specific immunity pre- and post-vaccination were compared by Dunnett's multiple comparison test (one-way ANOVA).

Roles of fibroblast growth factor-inducible 14 in hepatocellular carcinoma.

The prognostic value of the fibroblast growth factor-inducible 14 (Fn14) expression in hepatocellular carcinoma (HCC) is unknown. Real-time PCR (RT-PCR), western blot assays and immunohistochemistry analysis were here performed in order to compare Fn14 expressions in paired liver samples of HCC and normal liver tissue. Most of the tumor tissues expressed significantly higher levels of Fn14 compared to adjacent non-tumor tissues, with Fn14High accounting for 54.

Prevention of needle-tract seeding by two-step freezing after lung cancer biopsy.

Fine-needle aspiration biopsy is a method to detect malignancy for undetermined pulmonary nodules, but has the potential to spread malignant cells from the tumor to the pleural cavity or chest wall. We developed a two-step freezing method to avoid needle-tract seeding, by use of percutaneous cryoablation after biopsy but before the biopsy needle was removed. A man aged 72 years was admitted because of a large mass in right upper lobe.

[A method used in myeloma cell cloning spot image segmentation].

A new interactive image segmentation method used in the multiple myeloma cloning spots image segmentation is presented in the paper. Based on the theory of graph cuts, some pixels are selected as the front object and the background seeds, and the other parts are treated as the unknown region. Then, an energy function is constructed and initialized through K-means, and the minimum cut method is used in the segmentation by energy minimization.

Angelica sinensis: a novel adjunct to prevent doxorubicin-induced chronic cardiotoxicity.

Doxorubicin is an anthracycline antibiotic agent used in the treatment of a variety of solid and haematopoietic tumours, but its use is limited by formation of metabolites that induce acute and chronic cardiac toxicities. Angelica sinensis has been widely used to treat cardiovascular and cerebrovascular diseases in China. In the present study, we used an in vivo mouse model to explore whether A.

Trichoderma taxi sp. nov., an endophytic fungus from Chinese yew Taxus mairei.

Trichoderma taxi sp. nov. was isolated as an endophytic fungus of Taxus mairei growing at the Guanshan Nature Reserve of Jiangxi province, China, and characterized by a combination of phenotypic characteristics and gene analyses of ITS1 and 2, tef1 and rpb2 gene sequences.

Expression of HBcAg mutant with long internal deletion in Saccharomyces cerevisiae and observation of its self-assembly particles by atomic force microscopy (AFM).

An internally truncated C gene of adr hepatitis B virus core antigen with long internal deletion (aa81-aa116) (DeltaHBcAg with 36aa truncation) was expressed in Saccharomyces cerevisiae and the products (DeltarHBcAg) were purified from a crude lysate of the yeast by three steps: Sephrose CL-4B chromatography, sucrose step-gradient ultracentrifugation and CsCl-isopycnic ultracentrifugation. Results of ELISA test and density analysis of CsCl-isopycnic ultracentrifugation indicated that the purified products (DeltarHBcAg protein) with HBeAg antigenicity mainly located at the densities of 1.23 g ml-1.
