消化系统疾病诊治与组织病理诊断密切相关,高效、规范获取组织样本是关键,对此2021年欧洲胃肠内镜学会制定了消化道及肝胰腺胆道的内镜下组织活检的指南,分为上消化道（含肝、胰腺、胆道）和下消化道两部分,提供了规范活检的指导及建议。笔者对指南就上消化道内镜下组织活检的部分内容进行解读,解读内容为个人观点。

The diagnosis and treatment of digestive system diseases are closely related to histopathological diagnosis．Efficient and standardized acquisition of tissue samples plays a key role．In 2021,European Society of Gastrointestinal Endoscopy（ESGE）had developed guidelines for endoscopic tissue biopsy of the digestive tract and hepatopancreatic biliary tract,which divided into upper gastrointestinal tract（including liver,pancreas,biliary tract）and lower gastrointestinal tract．This guideline provided guidance and recommendations for standardizing biopsies．We interprets some of the contents of the guideline on tissue biopsy under endoscopy of the upper gastrointestinal tract,which are personal opinions．

目的 观察2型糖尿病大鼠肝脏组织中circRNA-0003340的表达,并探讨与糖尿病的关系。方法 选取健康雄性SD大鼠30只,随机分为2组,正常对照组（NC组,n=10）与2型糖尿病组（T2DM组,n=20）,检测FPG、FINs、HbA1c、TC、TG、HDL-C、LDL-C、AST、ALT;行腹腔注射糖耐量实验和胰岛素耐量实验,计算胰岛素抵抗指数（HOMA-IR）;HE染色观察胰岛细胞形态;RT-PCR检测大鼠肝脏组织circRNA-000334的表达量。结果 与NC组比较,T2DM组的AST、ALT、FPG、HAb1c、FINs、HOMA-IR、TG、TC、LDL-C均升高（P<0.05）,HDL-C降低（P<0.05）。circRNA-0003340在T2DM组肝脏组织中的表达较NC组肝脏组织中的表达是下调的,差异有统计学意义（P<0.05）。Sperman相关分析示大鼠肝脏组织中circRNA-0003340表达水平与FPG、TG及TC呈负相关（P<0.05）。结论 circRNA-003340的表达水平可能与T2DM大鼠的糖脂代谢密切相关,circRNA-003340在肝脏组织中的表达水平下调可能参与T2DM的发生发展。

Dysphagia is one of the common complications of chronic obstructive pulmonary disease（COPD）,and is one of the risk factors of acute exacerbation of COPD,which has adverse effects on the prognosis of patients．Accurate assessment of the occurrence and severity of dysphagia in COPD patients is the first step for scientific management．In this paper,the basic characteristics,application status and development status of assessment tools for COPD patients with dysphagia are reviewed,which can provide reference for the selection of assessment tools for clinical medical staff．

肝内胆管细胞癌（ICC）是发病率仅次于肝细胞癌的肝脏恶性肿瘤,它的恶性程度高、术后易复发,且早期无典型症状,大多数患者在确诊时已处于晚期。诊断主要依赖于增强CT、MRI和实验室检查。肝切除术是ICC首选的治疗方法,完整的切缘阴性切除和保留足够残留肝是影响手术预后的重要因素。淋巴结清扫、卡培他滨辅助化疗已被证实对患者有益。局部治疗、分子靶向治疗、免疫治疗等新疗法发展迅速,为晚期ICC患者带来了希望。传统疗法与新疗法的结合为ICC提供新的诊疗思路。

Intrahepatic cholangiocarcinoma（ICC）is the second most common liver malignancy after hepatocellular carcinoma．It is highly malignant,easy to recur after surgery,and has no typical symptoms in the early stage,and most patients are in the late stage when diagnosed．Diagnosis relies on enhanced CT,MRI and laboratory tests．Hepatectomy is the preferred treatment for intrahepatic cholangiocarcinoma．Complete resection with negative margin and adequate residual liver preservation are important factors affecting the prognosis of the operation．Lymph node dissection and adjuvant chemotherapy with capecitabine have been shown to be beneficial for patients．The rapid development of new therapies such as local therapy,molecular targeted therapy and immunotherapy has brought hope to patients with advanced intrahepatic cholangiocarcinoma．The combination of traditional therapy and new therapy provide a new idea for diagnosis and treatment of intrahepatic cholangiocarcinoma．
