Our results suggest that increased expression of NF-kappa B/RelA contributes to tumor angiogenesis in colorectal cancer. VEGF may play an important role in mediating the NF-kappa B/RelA angiogenic pathway.
SUMMARYBackground: Only limited data of the long-term effect of levosimendan on renal dysfunction in patients with decompensated heart failure (DHF) have been published previously. To date, there has been no similar study carried out in a Chinese population. Design and Methods: A prospective, randomized, placebo-controlled, and double-blind study was performed to investigate the effect of levosimendan on estimated glomerular filtration rate (eGFR) in DHF patients with renal dysfunction during a 30-day period. Sixty-six patients with left ventricular ejection fraction (LVEF) 40% and eGFR 15-89 mL/min/1.73 m
Background: Different sites of esophageal cancer are accompanied by different regional lymph node metastasis (LNM) risks. We aimed to investigate the impact of a lower tumor margin on abdominal LNM risk. Methods: We enrolled patients who underwent esophagectomy for esophageal squamous carcinoma (ESCC) from 2014 to 2017 in West China Hospital. Overall survival (OS) analysis was performed. We measured the distance between the lower tumor margin and esophagogastric junction (LED) with upper gastrointestinal contrast-enhanced X-ray (UGCXR). Multivariate logistic regression analysis and propensity score matching (PSM) were performed to explore the relationship between LED and the risk of abdominal LNM. Abdominal LNM risk in ESCC was stratified based on the location of the lower tumor margin. A model predicting abdominal LNM risk was constructed and presented with a nomogram. Results: The included patients had an abdominal LNM rate of 48.29%. In multivariate logistic regression analysis, LED was identified as a risk factor for abdominal LNM. Subgroup analysis of middle ESCC showed that patients with an LED less than 10 cm had a significantly higher rate of abdominal LNM than those with an LED greater than 10 cm. The abdominal LNM rate in middle ESCC patients with an LED less than 10 cm was 32.2%, while it was 35.1% in lower ESCC patients whose lower tumor margin did not invade the esophagogastric junction (EGJ), which was comparable after PSM. Conclusions: LED could help surgeons evaluate the risk of abdominal LNM preoperatively and better guide dissection of abdominal lymph nodes according to risk level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
