ABSTRACT
Cancer immunotherapy has recently emerged as a key strategy for cancer treatment. TREM2, a key target for regulating the tumor immune microenvironment, is important in cancer treatment and progression. TREM2 is an immune signaling hub that regulates multiple pathological pathways. It not only suppresses anti-tumor immune responses by inhibiting T cell-mediated immune responses, but it also influences tumorigenesis by affecting NK cell-mediated anti-tumor immunity. Noticeably, TREM2 expression levels also vary significantly among different tumor cells, and it can regulate tumor progression by modulating various signaling pathways. Above all, by summarizing the role of TREM2 in cancer immunotherapy and the mechanism by which TREM2 regulates tumor progression, this paper clarifies TREM2's role in both tumor progression and cancer therapy, identifying a new therapeutic target for oncology diseases.
ABSTRACT
Objective: To design and develop a disposable superfine catheter system for visual examination of bile and pancreatic ducts and predict its clinical application value. Methods: The superfine triple-lumen catheter and miniature photography technology were used to design and produce a disposable superfine catheter for visual examination of bile and pancreatic ducts, and animal experiments were conducted to compare said catheter and SpyGlass™. Results: The designed and developed disposable superfine catheter for visual examination of bile ducts with a diameter of 2.4â mm could enter the third-order and fourth-order bile ducts in the animal liver and also the gallbladder via the cystic duct for observation. The said catheter has a water injection rate of 0.8â mL/s, 0.16 megapixels, a resolution of 400 × 400, a depth of field of 0.3 to 20â mm, and a tilting up angle >90°. Conclusion: The new disposable catheter for visual examination of bile ducts has a superfine diameter, easier operation, and clearer imaging, and is expected to have a higher clinical practical value.
ABSTRACT
Glyphosate is a widely used herbicide. Acute glyphosate poisoning is not uncommon, mostly caused by a large amount of glyphosate entering the human body in a short time, and the common reason is taking it accidently. The manifestations of acute stage are mainly gastrointestinal reactions. The patient in the present study took glyphosate accidently. In the acute stage, the patient presented with nausea and vomiting, but no gastrointestinal bleeding or perforation was found. Upper gastrointestinal obstruction occurred after two months. Endoscopy revealed no abnormalities in the esophagus, but revealed multiple gastric scar changes, and pyloric obstruction. In addition, active gastric ulcer was also observed. Therefore, the choice of gastric lavage method, avoidance of neutralising acid-base reactions, and the long-term use of acid suppression and mucosal protection therapy may have important therapeutic implications for the repair of gastric mucosa in such cases. Key Words: Glyphosate, Ulceration, Pyloric obstruction.

BACKGROUND: Esophageal motility disorders which include achalasia, esophagogastric junction outflow obstruction (EGJ outflow obstruction), jackhammer esophagus (JE), distal esophageal spasm (DES), etc. are rare disease of unknown causes. The diagnosis is based on endoscopy, barium meal, and high-resolution manometry (HRM). With the development of endoscopy, peroral endoscopic myotomy (POEM) has emerged as a standard method for the treatment of achalasia. PURPOSE: The purpose of this article is to enable gastroenterologists to have a more comprehensive understanding of the application status, technical characteristics, clinical efficacy and future prospect of POEM in the treatment of esophageal motility disorders. METHODS: Through a large number of reading literature, combined with clinical practice, summary and analysis of the indications, procedure, efficacy, complications, and controversies of POEM in the treatment of esophageal motility disorders, as well as the current and future perspectives of POEM were studied. RESULTS: POEM is safe and effective in the treatment of esophageal motility disorders, but the GERD reflux rate is higher. CONCLUSIONS: POEM can be a new option for the treatment of esophageal movement disorders, but large sample, multi-center, long-term study reports are needed, and it promotes the development of NOTES technology.
