简介:AbstractArtificial intelligence (AI) is now a trendy subject in clinical medicine and especially in gastrointestinal (GI) endoscopy. AI has the potential to improve the quality of GI endoscopy at all levels. It will compensate for humans’ errors and limited capabilities by bringing more accuracy, consistency, and higher speed, making endoscopic procedures more efficient and of higher quality. AI showed great results in diagnostic and therapeutic endoscopy in all parts of the GI tract. More studies are still needed before the introduction of this new technology in our daily practice and clinical guidelines. Furthermore, ethical clearance and new legislations might be needed. In conclusion, the introduction of AI will be a big breakthrough in the field of GI endoscopy in the upcoming years. It has the potential to bring major improvements to GI endoscopy at all levels.

简介:AbstractGastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasm of the digestive system and are not sensitive to traditional chemotherapy. Therefore, historically, surgical resection was the only effective therapy. However, the emergence of tyrosine kinase inhibitors (TKIs) has revolutionized the treatment of GISTs, because they target c-Kit and PDGF receptor-α (PDGFRA), which are important in GIST development and progression. As research into c-Kit and PDGFRA continues, an increasing number of different TKIs are being used in the clinical setting. This review aims to discuss the current state of chemotherapy for the treatment of GISTs with different genotypes.

简介:目的:讨胃经穴在胃肠实热型肥胖症治疗中的作用。方法:51例胃肠实热型肥胖症患者随机分为两组,治疗组以胃经取穴为主,对照组采用俞募配穴法取穴。隔日治疗1次,1个月为1个疗程,共治疗3个疗程。观察患者的症状、体征的变化,测量治疗前后的肥胖指标及血瘦素、血脂、血糖、ACHE等实验室指标。结果:与对照组相比,胃经组可显著减少各项肥胖指标(P〈0.01);改善肥胖患者的高瘦素血症(P〈0.05)和脂代谢紊乱(P〈0.05);逆转肥胖患者的副交感神经功能亢进的失衡状态(P〈0.05)。结论:经穴位可以作用于肥胖发生和发展的多个环节,是治疗胃肠实热型肥胖症的关键而有效的选穴。
