To determine the mechanisms of gastric mucosal injury associated with Helicobacter pylori infection, we investigated the contents of cytokines and inflammatory cell infiltration in the gastric mucosa. Ninety-six patients with dyspepsia were studied (58 gastric ulcer, 38 nonulcer dyspepsia). Of the 96 patients, 63 were infected with H. pylori as determined by microscopic examination with HE staining, culture of H. pylori, or the rapid urease test. Endoscopic biopsy specimens were obtained from both the antrum and the body to examine interleukin (IL)-8, IL-6, IL-1 beta, and tumor necrosis factor-alpha contents in the gastric mucosa by enzyme-linked immunosorbent assay. Inflammatory cell infiltration was assessed according to the Sydney system. IL-8 content was enhanced in both the antral and body mucosa of the H. pylori-positive patients compared with the H. pylori-negative patients. Furthermore, IL-8 content correlated well with the infiltration of both mononuclear cells and polymorphonuclear cells. These results suggest that IL-8 plays important roles in the pathogenesis of gastric mucosal injury associated with H. pylori infection.

This study is aimed at comparing the clinical characteristics and histological types of symptomatic and asymptomatic patients with heterotopic gastric mucosa in the upper esophagus (HGMUE) and exploring the factors influencing the occurrence and severity of laryngopharyngeal reflux (LPR) symptoms in these patients. HGMUE is a potential cause of LPR symptoms. This retrospective analysis evaluated 70 patients with HGMUE using a detailed questionnaire.

Objective: To investigate the role of heparan sulfate 6-O-sulfotransferase 2 (HS6ST2) in gastric cancer (GC).
Methods: HS6ST2 expression in GC and adjacent normal gastric mucosa was first detected via immunohistochemical (IHC) staining. The correlation between the expression level of HS6ST2 and clinicopathological parameters were observed.

Gastric cancer (GC) ranks among the top five most diagnosed cancers globally, with particularly high incidence and mortality rates observed in Asian regions. Despite certain advancements achieved through early screening and treatment strategies in many countries, GC continues to pose a significant public health challenge. Approximately 20% of patients infected with develop precancerous lesions, among which metaplasia is the most critical.

Purpose: Daily online adaptive radiation therapy (oART) opens the opportunity to treat gastric mucosa-associated lymphoid tissue (MALT) lymphoma with a reduced margin. This study reports our early experience of cone beam computed tomography (CBCT)-based daily oART treating gastric MALT lymphoma with breath-hold and reduced margins.
Methods And Materials: Ten patients were treated on a CBCT-based oART system.

Objective: To investigate the role of endoscopic ultrasonography (EUS) in the diagnosis and treatment of upper gastrointestinal bleeding of unknown origin in liver cirrhosis, focusing on patients with recurrent treatment of esophageal and gastric varices who failed to identify the bleeding site under direct endoscopy.
Background: Esophagogastric variceal bleeding is one of the severe complications of decompensated liver cirrhosis, and serial endoscopic therapy can improve the long-term quality of life of patients. Most acute bleeding can be detected under direct endoscopy with thrombus or active bleeding, but there are still some patients with recurrent bleeding after repeated treatments, and it is difficult to find the bleeding site, especially in gastric variceal bleeding.
