Objective: To investigate the mechanism of Ghrelin/GHS-R signaling pathway in small intestine injury induced by NSAIDs related enteropathy. To clarify the mechanism network of intestinal mucosal repair with naringin as a new therapeutic method.
Methods: Naringin was used as the intervention method, observed the damage of small intestinal mucosa and detected the expression of ghrelin, GHS-R, leptin and TNF-α by electron microscopy, HE staining and immunohistochemistry.
Results: Compared with the control group, the weight of rats in the model group decreased, the thickness of intestinal mucosa became thinner, the structure of intestinal mucosa changed, the expression of ghrelin, GHS-R and leptin decreased, the expression of TNF-α increased. Compared with the model group, the intestinal mucosa of the treatment group was repaired, the expression of ghrelin, GHS-R and leptin was increased, and the expression TNF-α was decreased.
Conclusion: The mechanism of intestinal mucosal damage in patients with NSAIDs related enteropathy may be related to the decreased expression of ghrelin, GHS-R and leptin, and promotion of TNF-α secretion. Naringin can effectively promote the secretion of ghrelin and leptin, the expression of GSH-R, and inhibit the release of TNF-α, so as to repair intestinal mucosa naringin will become a new method to treat and prevent NSAIDs related intestinal diseases.

Dysregulation at the intestinal epithelial barrier is a driver of inflammatory bowel disease (IBD). However, the molecular mechanisms of barrier failure are not well understood. Here, we demonstrate dysregulated mitochondrial fusion in intestinal epithelial cells (IECs) of patients with IBD and show that impaired fusion is sufficient to drive chronic intestinal inflammation.

Inflammatory bowel disease, particularly Crohn's disease (CD), has been linked to modifications in mesenteric adipose tissue (MAT) and the phenomenon known as "creeping fat" (CrF). The presence of CrF is believed to serve as a predictor for early clinical recurrence following surgical intervention in patients with CD. Notably, the incorporation of the mesentery during ileocolic resection for CD has been correlated with a decrease in surgical recurrence, indicating the significant role of MAT in the pathogenesis of CD.

Autoimmune enteropathy (AIE) is a rare immune mediated disorder primarily affecting children, characterized by chronic diarrhea, malabsorption, vomiting, weight loss and villous atrophy. It has also been observed in adults presenting diagnostic and treatment challenges due to its overlap with other gastrointestinal disorders such as celiac disease. Initial diagnostic criteria for AIE include small bowel villous atrophy, lack of response to dietary restrictions, presence of anti-enterocyte antibodies, and predisposition to autoimmunity without severe immunodeficiency.

This case report describes the poisoning of two mares from the same paddock with (Black locust) bark. The poisoning manifested itself by the sudden onset of weakness and fever with transient improvement after the administration of non-steroidal anti-inflammatory drugs and fluids. After the initial stabilisation, the mares were left unattended overnight.

The widespread prevalence of colorectal cancer and its high mortality rate emphasize the urgent need for more effective therapies. When developing new drug products, a key aspect is ensuring that sufficiently high concentrations of the active drug are reached at the site of action. Drug transporters and drug-metabolizing enzymes can significantly influence the absorption and local accumulation of drugs in intestinal tissue.
