Chronic gastritis is one of the common diseases of the digestive system. It has the characteristics of repeated attacks and a long course of disease. It is often accompanied by anxiety and depression. There are various ways to treat chronic gastritis with anxiety and depression. The combination of traditional Chinese and Western medicine can be used to treat chronic gastritis with anxiety and depression, and the individualized treatment based on disease differentiation and syndrome differentiation may be a new treatment.

During the period of the troops in warm area rush into the border of alpine area, the low temperature environment can have obvious influence on the gastrointestinal mucosal barrier, brain gut axis, gastrointestinal motility and gastrointestinal electric activity. This paper mainly discusses the mechanism of action, and puts forward the improvement measures of non-drugs, drugs and traditional Chinese medicine, so as to ensure the combat effectiveness of soldiers in the alpine environment.

Probiotics can restore the balance of intestinal flora and mucosal barrier function to treat related diseases. Its safety and effectiveness have been clinically proven. The clinical application of probiotics in common digestive diseases containing antibiotic related diarrhea, ulcerative colitis, diarrhea type irritable bowel syndrome, functional constipation and chronic liver disease were reviewed. It is hoped to lay a foundation for better development and application of probiotics.

Colorectal cancer is one of the most common malignant tumors of the digestive system.Early detection of primary lesions, metastatic lesions and recurrent lesions can guide clinical treatment and assess the prognosis.Imaging diagnosis plays an important role in the diagnosis and treatment of colorectal cancer.Now, the accuracy of tumor staging has been improved with the development of new technologies such as dual-source CT, multimodal MRI technology, PET/CT, contrast-enhanced ultrasonography, simultaneously, various parameters can also evaluate tumor grade, blood supply et al, which is helpful for accurate diagnosis and individualized treatment of tumors.This article summarizes the related research results and reviews the current status and application of imaging methods in the diagnosis and treatment of colorectal cancer and liver metastasis.

Transjugular intrahepatic portosystemic shunt (TIPS) is a common minimally invasive interventional technique for the treatment of liver cirrhosis patients with esophagus and gastric varices and intractable ascites. At present, portal vein puncture is still the difficulty and bottleneck of the operation. Repeated puncture of portal vein may lead to serious complications or even death during perioperative period. Traditionally, vein puncture is an experiential puncture under fluoroscopy, which is blind to some extent and depends heavily on the experience of the operators. In order to reduce the number of puncture times and optimize the accuracy, a variety of puncture guidance techniques have emerged in clinical practice, including direct portal vein puncture marker, CO₂ portal venography marker, real-time bedside ultrasound guidance, and image fusion assistance. These puncture guidance techniques have their own advantages and disadvantages and are evolving in practice. Among them, the potential of image fusion technology is gradually released, which makes portal vein puncture guidance more intelligent, intuitive and concise, and makes TIPS safer. This paper summarizes the progress of this technique.

神经内分泌肿瘤（neuroendocrine neoplasms，NENs）的发病率呈逐渐升高趋势，其中胃肠胰神经内分泌肿瘤（gastroenteropancreatic neuroendocrine neoplasms，GEP-NENs）约占所有NENs的2/3，具有高度的临床异质性^[1,2]。依据GEP-NENs的临床表现、生物标记物及影像特征，对病变进行准确诊断、分期和随访，对制定治疗方案和改善预后均具有重要意义^[1,2,3,4]。随着消化内镜和影像学技术的进步，GEP-NENs的诊治水平也有了很大的提高。临床常用的影像和内镜检查手段包括CT、MRI、核医学、体表超声、胃肠内镜、放大内镜、超声内镜等，这些检查方法各有其优势及不足^[4,5,6,7]。为使临床医生更好地认识NENs的影像学特点，选择最优化的影像学检查方法，国内相关专家参考国内外最新指南和相关文献，并结合临床实际情况起草了本版GEP-NENs影像学诊断专家共识，供广大临床和影像医师参考。

This paper reviews and summarizesthe diagnostic criteria, pathogenesis, epidemiological studies and treatment methods of irritable bowel syndrome(IBS)by combing relevant literature at home and abroad.In the future, IBS willmake breakthroughs in the following research areas in the future, for instance: the improvement of research methods and the acquisition of real data, the exploration of the treatment on special groups(for example on soldiers), the research of personnel performing special tasks, and the exploration of new treatment methods, such as probiotics, vitamins, psychotherapy and immunotherapy.

Gastric varices(GV), as one of the complications of portal hypertension, has a lower incidence than esophageal varices, but bleeding from GV is not easy to control and associated with a high rebleeding rate and high mortality.GV has different characteristics of vascular anatomy and hemodynamics from esophageal varices, with a unique corresponding clinical management strategy.In order to deepen the understanding of GV hemodynamic characteristics and formulate an individualized treatment strategy for GV bleeding, the Minimally Invasive Intervention Collaboration Group of the Gastroenterology Branch of the Chinese Medical Association invites some experts in this field to formulate this consensus.
