Objectives: Colorectal endoscopic submucosal dissection (ESD) is challenging because of the difficulty in adequately visualizing the submucosal layer. Many traction methods have been developed to facilitate submucosal dissection; however, they are not widely applied. Therefore, we designed a new traction device, a traction ring, and conducted this pilot study to evaluate its feasibility and safety for colorectal ESD.

- COX-2 and 5-LOX enzymes are found to be overactive in esophageal squamous cell carcinoma (ESCC), prompting this study to explore how inhibiting these enzymes affects cancer growth.
- The inhibitors, Nimesulide (for COX-2) and AA861 (for 5-LOX), were shown to reduce cell growth and promote cell death, as well as decrease specific inflammatory substances (PGE(2) and LTB(4)).
- Animal tests revealed that treated tumors were significantly smaller, with lower cell proliferation rates, supporting the idea that using both inhibitors together might be more effective against ESCC than using either one alone.
Aim: To compare the prevalence of H pylori infection, peptic ulcer, cytomegalovirus (CMV) infection and Candida esophagitis in human immunodeficiency virus (HIV)-positive and HIV-negative patients, and evaluate the impact of CD4 lymphocyte on H pylori and opportunistic infections.
Methods: A total of 151 patients (122 HIV-positive and 29 HIV-negative) with gastrointestinal symptoms were examined by upper endoscopy and biopsy. Samples were assessed to determine the prevalence of H pylori infection, CMV, candida esophagitis and histologic chronic gastritis.
