Comparison of the characteristics of the CF-H290I and PCF-Q260JI colonoscopes in non-sedated patients with a history of abdominal or pelvic surgery: a randomized controlled study.

Background And Aim: The purpose of this randomized controlled study was to compare the characteristics of the CF-H290I (high-definition) colonoscope with those of the PCF-Q260JI (high-resolution) colonoscope in non-sedated patients with a history of abdominal or pelvic surgery in an effort to help endoscopists to select more effectively and objectively between the various colonoscopes.

Methods: A total of 397 patients who underwent colonoscopy at the Affiliated Wuxi People's Hospital of Nanjing Medical University, between August 2022 and October 2022 were randomized to a CF-H290I group (n = 198) or a PCF-Q260JI group (n = 199) using a computer-generated allocation method. We compared the adenoma detection rate (ADR), patient satisfaction with the examination, discomfort associated with colonoscopy including abdominal distension and pain, cecal intubation time, and patient willingness to undergo colonoscopy in the future between the CF-H290I and PCF-Q260JI groups.

A superficial esophageal cancer with a diverticulum cured by endoscopic submucosal dissection.

Esophageal diverticulum are rare. However, Esophageal cancer that involves diverticula is relatively rare. Here we reported a rare case of a superficial esophageal cancer with an esophageal diverticulum, which was invisible before the endoscopic submucosal dissection.

PTPRO exaggerates inflammation in ulcerative colitis through TLR4/NF-κB pathway.

Previous studies have implicated protein tyrosine phosphatase receptor type O (PTPRO) as a key regulator in inflammation-associated diseases; however, its role in ulcerative colitis (UC) remains largely unknown. Thus, we aim to elucidate the potential role and underlying mechanism of PTPRO in UC. In this study, increased expression of PTPRO, toll-like receptor (TLR4) and inflammatory cytokines were observed in mucosal tissues (MTs) from inflamed areas and lamina propria mononuclear cells (LPMCs) of patients with UC compared with those from healthy controls.

Metabolic Perturbation and Potential Markers in Patients with Esophageal Cancer.

Clinical diagnosis of esophageal cancer (EC) at early stage is rather difficult. This study aimed to profile the molecules in serum and tissue and identify potential biomarkers in patients with EC. A total of 64 volunteers were recruited, and 83 samples (24 EC serum samples, 21 serum controls, 19 paired EC tissues, and corresponding tumor-adjacent tissues) were analyzed.
