Effect of various doses of low-tense laser irradiation on proliferative and functional morphology of fundal gastric epitheliocytes in rats was studied by endogastric irradiation with the methods of histochemistry, autoradiography, transmission and scanning electron microscopy. It was shown that laser irradiation effect varied with its dose and was spread on gastric mucosa lying at the site of direct influence. The doses of irradiation that had no alternative effect induced reconstruction of epitheliocytes especially mucocytes indicating intensification of specific function in them, as well as an increase of proliferative activity.

To investigate the clinicopathological features, diagnosis, genetic alterations, and biological behaviors of hamartomatous inverted hyperplastic polyp (HIHP) in the gastrointestinal tract. The clinical, sonographic, endoscopic and pathologic data of 10 HIHP cases diagnosed at the First Affiliated Hospital of Air Force Medical University, Xi'an, China from January 2013 to March 2024 were collected. Their clinicopathological features and histological morphology were analyzed.

The integrity of esophageal epithelial cells in patients with gastroesophageal reflux disease (GERD) or GERD-like symptoms is the first mechanism of protection to decrease the sensitivity to gastric reflux and heartburn symptoms. We investigated the protective effects of Poliprotect (PPRO), a CE-marked medical device, on esophageal epithelial integrity using in vitro and ex vivo models. In vitro, the protective effects of PPRO were tested on Caco-2 cells.
