RESUMO

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. RESULTS: There was no statistically significant difference in the overall ADR between the CF-H290I and PCF-Q260JI groups (81 [40.9%] vs 63 [31.7%], Z = 3.674, P = 0.055). However, the ADRs in the transverse colon and left colon were significantly higher in the CF-H290I group (22 [11.1%] vs 6 [3.0%], Z = 9.588, P = 0.002 and 57 [28.8%] vs 37 [18.6%], Z = 5.212, P = 0.017, respectively). More sessile serrated lesions were detected in the CF-H290I group (52 [26.3] vs 30 [15.1%], Z = 7.579, P = 0.006). Patient satisfaction with colonoscopy was better in the PCF-Q260JI group (8.91 ± 1.09 vs 8.51 ± 1.44, t = -3.158, P < 0.01) with less likelihood of discomfort (23 [11.6%] vs 41 [20.7%], Z = 6.144, P = 0.013), The number of patients willing to undergo colonoscopy in the future was significantly greater in the PCF-Q260JI group (168 [84.4%] vs 149 [75.3%], Z = 5.186, P = 0.023). The cecal intubation time was significantly shorter in the CF-H290I group (256.09 ± 155.70 s vs 315.64 ± 171.64 s, P = 0.004). There were no complications such as perforation or bleeding in either group. CONCLUSION: The CF-H290I and PCF-Q260JI colonoscopes each have advantages when used in patients with a history of abdominal or pelvic surgery. The CF-H290I has higher ADRs in the transverse and left colon whereas the PCF-Q260JI is less painful and better accepted by patients. This study was approved by the Clinical Research Ethics Committee of Wuxi People's Hospital and was registered in the Chinese Clinical Trial Registry (ChiCTR2200063092).

RESUMO

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. The cancer was successfully removed by ESD with no perforation.

RESUMO

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. Then, it was manifested that PTPRO promoted the expression of TLR4 and proinflammatory cytokines in lipopolysaccharide-induced (LPS-induced) inflammatory macrophage model. Besides, PTPRO inhibited the proliferation of intestinal epithelial cells (IECs) but enhanced the apoptosis of IECs in macrophages. Moreover, levels of phosphorylated nuclear factor κB (NF-κB)/p65 and inhibitor of NF-κB α (IκBα) were more significantly increased in PTPRO overexpressed macrophages. In addition, the area under receiver operating characteristic curve was 0.807 (95%CI = 0.686-0.958, P < .001) suggesting PTPRO as an ideal diagnostic marker for UC. Taken these, the present study shows strong evidence that PTPRO exaggerates inflammation in UC via TLR4/NF-κB signaling pathway.

RESUMO

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. The gas chromatography time-of-flight mass spectrometry (GC/TOF-MS) was employed, and principal component analysis was used to reveal the discriminatory metabolites and identify the candidate markers of EC. A total of 41 in serum and 36 identified compounds in tissues were relevant to the malignant prognosis. A marked metabolic reprogramming of EC was observed, including enhanced anaerobic glycolysis and glutaminolysis, inhibited tricarboxylic acid (TCA) cycle, and altered lipid metabolism and amino acid turnover. Based on the potential markers of glucose, glutamic acid, lactic acid, and cholesterol, the receiver operating characteristic (ROC) curves indicated good diagnosis and prognosis of EC. EC patients showed distinct reprogrammed metabolism involved in glycolysis, TCA cycle, glutaminolysis, and fatty acid metabolism. The pivotal molecules in the metabolic pathways were suggested as the potential markers to facilitate the early diagnosis of human EC.
