BACKGROUND Currently,there is insufficient data about the accuracy in the diagnosing of pancreatic cystic lesions(PCLs),especially with novel endoscopic techniques such as with direct intracystic micro-forceps biopsy(mFB)and needle-based confocal laser-endomicroscopy(nCLE).AiM To compare the accuracy of endoscopic ultrasound(EUS)and associated techniques for the detection of potentially malignant PCLs:EUS-guided fine needle aspiration(EUS-FNA),contrast-enhanced EUS(CE-EUS),EUS-guided fiberoptic probe cystoscopy(cystoscopy),mFB,and *** This was a single-center,retrospective *** identified patients who had undergone EUS,with or without additional diagnostic techniques,and had been diagnosed with *** determined agreement among malignancy after 24-mo follow-up findings with detection of potentially malignant PCLs via the EUSguided techniques and/or EUS-guided biopsy when available(EUS malignancy detection).RESULTS A total of 129 patients were included, with EUS performed alone in 47/129. in 82/129 patients,EUS procedures were performed with additional EUS-FNA (21/82), CE-EUS (20/82), cystoscopy(27/82), mFB (36/82), nCLE (44/82). Agreement between EUS malignancy detection and the 24-mo follow-up findings was higher when associated with additional diagnostic techniques thanEUS alone [62/82 (75.6%) vs 8/47 (17%);OR 4.35, 95%Ci: 2.70-7.37;P ighestmalignancy detection accuracy was reached when nCLE and direct intracystic mFB were bothperformed, with a sensitivity, specificity, positive predictive value, negative predictive value andobserved agreement of 100%, 89.4%, 77.8%, 100% and 92.3%, respectively (P ith EUS-alone).CONCLUSiONThe combined use of EUS-guided mFB and nCLE improves detection of potentially malignantPCLs compared with EUS-alone, EUS-FNA, CE-EUS or cystoscopy.

在现代教育环境下,网络多媒体资源的开发已经允许发展新的教学理念和方法。高等教育的发展需要教师和学生利用在线学习资源,以获得更直接的师生交流。这就是为什么iCT教学的概念逐渐在日常教学中深入,并相互交融。网络在线资源的类型有很多种:从论坛,线上图书馆等等在线虚拟学习环境。在某种程度上,在线教学与面对面教学的三大优势分别是:及时性,灵活性和交互性。有很多关于这种教学技术的研究课题,旨在探索在线学习技术,使学生和教师从中获得更好的学习体验和效率。因此在学生的学习过程中对其使用的软件,内容产生意见和反馈。教师与学生进行教-学互动时,双方这个过程做出不同的理解。所以,在此引出教育研究去了解新一代的学生需要用什么方式去更好的学习。
