Article Abstract
To examine the protective effect and mechanism of the original extract of Dendrobium officinale (DE) on gastric lesions caused by aspirin (ASA) facilitate the development of traditional Chinese medicine products. In this study, a gastric lesions rat model was established, and then the rats were treated with DE for 5 days. We found that ASA-induced gastric mucosal detachment and hemorrhagic lesions in rats improved after DE supplementation. Meanwhile, effectively inhibits the secretion of inflammatory mediators (IL-6, IL-1β, TNF-α, MPO, COX-2) and upregulates the activity of antioxidant core components (T-SOD, GSH-Px) and defense factors (TFFs, EGF, EGFR) in gastric tissues. It was further found that DE exerted a defensive effect on the gastric mucosa in association with NF-κB/Nrf-2/HO-1 signaling. In conclusion, DE protects the gastric mucosa from oxidative stress, improves its defenses, as well as being a potential gastric mucosal nutrient in the future, preventing ASA-induced gastric lesions.

Gastric metastasis of breast cancer is rare, and clinical data on its treatment and prognosis are limited at present. Herein, we report a case of gastric metastasis arising from invasive ductal and mucinous carcinoma of the breast and review the literature. A 51-year-old woman was diagnosed with infiltrating and mucinous carcinoma of the right breast accompanied by ipsilateral axillary lymph node and subclavian lymph node metastases.

A 73-year-old male was admitted to our department with complaints of upper abdominal distension, accompanied by dull pain and belching for more than 10 days. Gastroscopy revealed a broad-based raised lesion, approximately 1.0 cm in diameter, on the anterior wall of the gastric body, with a central star-shaped depression, erosion, and surrounding congestion.

Background: Damage to peri-esophageal tissue may occur following pulmonary vein isolation (PVI). Active esophageal cooling has been shown to reduce the incidence of mucosal esophageal injury, probably by dissipation of heat and inhibition of inflammation. Whether it also protects the peri-esophageal vagal nerve plexus and reduces gastric hypomotility and food retention is uncertain.

In the field of gastrointestinal oncology, the development of novel artificial intelligence (AI) processes may help with multiple aspects of cancer care delivery. However, a comprehensive understanding of the current utility of AI in gastrointestinal oncology is lacking. The authors conducted searches in the following databases: MEDLINE (Ovid), Embase (Ovid), and CINAHL (Cumulative Index of Nursing and Allied Health) Ultimate (EBSCO).
