Nordihydroguaiaretic acid (NDGA) is a natural phenolic compound isolated from the creosote bush Larrea divaricata, which has anti-tumor activities both in vitro and in vivo. Its analogs are in clinical development for use in refractory solid tumors. But the mechanisms underlying the anti-cancer effect of NDGA are not fully understood. In this study, we(More)
BACKGROUND AND OBJECTIVE The reading of capsule endoscopy (CE) is time-consuming. Thus, several time-saving features have been added to the CE software by different CE companies. However, the similar pictures elimination mode in the OMOM capsule endoscopy software has not been evaluated yet. Our aim is to evaluate the sensitivity and specificity of the(More)
BACKGROUND The associations between toll-like receptor 2 (TLR2) and toll-like receptor 4(TLR4) polymorphisms and inflammatory bowel disease (IBD) susceptibility remain controversial. A meta-analysis was performed to assess these associations. METHODS A systematic search was performed to identify all relevant studies relating TLR2 and TLR4 polymorphisms(More)
BACKGROUND Behcet's disease (BD) is a systemic inflammatory disease with the histopathological features of leukocytoclastic vasculitis that affects nearly all organs and systems. When it involves the intestine, it is called entero-Behcet's disease (entero-BD). CASE PRESENTATION Here we described a 23-year-old man with entero-BD refractory to conventional(More)
The improvement and implementation of a colonoscopy technique has led to increased detection of laterally spreading tumors (LSTs), which are presumed to constitute an aggressive type of colonic neoplasm. Early diagnosis and treatment of LSTs is clinically challenging. To overcome this problem, we employed iTRAQ to identify LST-specific protein biomarkers(More)
Dear Editor: We present a case of acute glutaraldehyde-induced colitis following polyps treated by endoscopic mucosal resection (EMR). A previously healthy, 56-year-old man underwent a screening colonoscopy after regular bowel cleansing with macrogol electrolytes powder in Endoscopy Center of Nan Fang Hospital in June 2013. Three polyps 6–8 mm in diameter(More)
Small rectal carcinoid tumors (<10 mm) are often removed via endoscopic submucosal dissection (ESD). However, the use of ESD for tumors of an intermediate size (7–16 mm) is less well documented. This study aimed to evaluate the efficacy and safety of ESD compared with endoscopic mucosal resection using a cap (EMR-C) for the treatment of 7–16-mm rectal(More)
BACKGROUND Endoscopic polypectomy is believed to reduce the incidence of colorectal cancer, and it has become a standard practice for the removal of gastrointestinal polyps. However, for patients with implanted cardiac devices, endoscopic polypectomy is thought to be relatively contraindicated. Aside from two case reports from around 10 years ago, few(More)
