1Preoperative rectosigmoid endoscopic ultrasonography predicts the need for bowel resection in endometriosis显示文摘BACKGROUND Rectosigmoid endometriosis is an underdiagnosed disease responsible for abdominal pain, transit disorders and rectal bleeding. Two surgical approaches,rectosigmoid bowel resection(segmental or patch) or intramuscular layer dissection(shaving), are available.AIM To assess whether the lesion features observed via preoperative rectosigmoid endoscopic ultrasonography(RS-EUS) might predict the need for bowel resection.METHODS This multicentric retrospective study was conducted on patients with rectosigmoid endometriosis who underwent a curative surgical procedure,evaluated by RS-EUS performed by two trained operators, between January 2012 and March 2018. A univariate statistical analysis was performed on nodules' RSEUS features(thickness, width, infiltration of the submucosae, presence of a bump into the digestive lumen and presence of multiple rectosigmoid localizations). A multivariate logistic regression was then performed on the significant results.RESULTS Of the 367 patients, 73 patients with rectosigmoid endometriosis were evaluated by RS-EUS and underwent rectosigmoid surgery. After the univariate analysis was completed, thickness, width and infiltration of the submucosae were identified as potential predictive factors for bowel resection. In a multivariate logistic regression model, only thickness appeared to be a significant [odds ratio(OR) = 1.49, 95% confidence interval(CI): 1.04-2.12, P = 0.028] predictive factor for bowel resection. Receiver operating characteristic analysis performed showed that a thickness over 5.20 mm might be used as cut-off with a sensitivity of 76%, a specificity of 81%, and an area under carve = 0.82. The cut-off values for 100%sensitivity and 100% specificity were 0.90 mm and 10.00 mm, respectively. A trend concerning width to predict the need for resection was also observed(OR1.12, 95%CI: 1.00-1.26, P = 0.054)CONCLUSION The presence of a rectosigmoid nodule of endometriosis greater than 5.20 mm thick on RS-EUS might predict the need for bowel resection.Victor Desplats René-Louis Vitte Joseph du Cheyron Gilles Roseau Arnaud Fauconnier Frédérick Moryoussef 2019World Journal of Gastroenterology2019,25,6:9
2基于斑马鱼胚胎急性毒性测试预测食用油毒性可行性研究显示文摘探讨利用斑马鱼胚胎预测食用油毒性的可行性。用乙腈和正己烷联合提取采自我国台湾地区的7个不同品质的猪油样本,并用甲醇溶解,然后用斑马鱼胚胎测试提取物的毒性,最后用非靶标高分辨率复合四极杆质谱仪偶联超高液相色谱/质谱系统进一步分析低毒、中毒、高毒代表性样本中的化学组成,结合ChemSpider、CT-link和Vega软件分析预测有毒物质的结构和功能。结果表明,不同品质的猪油样本毒性差异大,高毒性猪油的特征性质荷比信号相对应的化学成分为脂肪酸的氧化物,是样本的潜在有毒成分。斑马鱼胚胎急性毒性测试可准确地预测猪油品质,该方法为评估食用油安全提供了一个新的思路。朱燕华 王钟凰 李昱宗 EI-NEZAMI Hani NORINDER Ulf COTGREAVE Ian A DE VITTE Peter 陈雪平 2020中国油脂2020,45,12:2
