Objective: To study the effect of Jinguo Weikang Capsule [see text] on the gene expression of H-ras, epidermal growth factor receptor (EGFR), P53 and C-myc of the gastric mucosa in rats with gastric precancerous lesions, and to investigate the action mechanism of JWC on gastric precancerous lesions.
Methods: A rat model with paratypical proliferation of the gastric epithelium mucosa was established by using 60Co irradiation. Rats were divided into the normal group, model group, high-, medium-, low-dose JWC treatment groups, and the vitacoenzyme control group, and were treated for 30 days. The expression of H-ras, EGFR, P53 and C-myc genes of the gastric mucosa was detected by using immunohistochemical methods.
Results: The expression and over-expression rates of H-ras, EGFR, P53 and C-myc gene in the high-and medium-dose JWC treatment groups were significantly lower (P<0.05) as compared with those of the model group.
Conclusion: JWC can inhibit the expression of the H-ras, EGFR, P53 and C-myc genes expression of the gastric mucosa in rats, which may be one of mechanisms involved in suppressing or reversing gastric carcinogenesis.

Background: Barrett's mucosa in the remnant esophagus (BMRE) is often identified after gastric pull-up reconstruction after esophagectomy. This study aimed to determine the clinical characteristics of BMRE and the factors that affect the development of BMRE.
Methods: The characteristics of BMRE and factors affecting its occurrence were studied in patients with subtotal esophagectomy and gastric pull-up reconstruction who survived at least 3 years after esophageal cancer surgery and who were evaluated by endoscopy.

Introduction And Aim: Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are rare neoplasms originating in neuroendocrine cells from the gastric mucosa and submucosa, small intestine, large intestine, rectum, and pancreas. Our aim was to describe their histopathologic, endoscopic, and clinical characteristics and the experience with these tumors at a tertiary care hospital center in the Colombian Southwest.
Materials And Methods: A retrospective, analytic, observational, and descriptive study included 93 patients diagnosed with GEP-NETs, within the time frame of 2018 and 2022.

Gastric cancer (GC) is a malignant tumor originating from the epithelial cells of the gastric mucosa. The 5-methylcytosine (mC) modification refers to the addition of a methyl group to the fifth carbon atom of cytosine in RNA molecules. This study aimed to investigate the role of NOL1/NOP2/SUN domain (NSUN)6 in GC and its underlying molecular mechanisms.

Histologic gastric eosinophilia (HGE), characterized by dense eosinophil infiltration in gastric mucosa, is an understudied disease with unclear etiology. Unlike its counterpart, eosinophilic esophagitis (EoE), which has defined diagnostic eosinophil thresholds and characteristic endoscopic findings, proposed eosinophil thresholds for the diagnosis of HGE vary and endoscopic findings are not well characterized. This study aimed to assess the clinical, histological, and endoscopic features of HGE in adults and children.

Purpose: Precancerous lesions of gastric cancer (PLGC) represent a crucial juncture in the transformation from gastritis to gastric cancer. Qijie Xiaopi Decoction (QJXPD), a Chinese herbal medicine formulation that has been applied in clinical practice to manage PLGC, which is capable of effectively relieving the symptoms experienced by patients such conditions. However, its mechanism of action remains unclear.
