With the construction and development of head and neck tumor, diagnosis and treatment technology and survival rate of patients have been improved in different degrees. Nurses play an important role as managers and practitioners in the treatment and rehabilitation of patients with head and neck tumors, and it is very important to evaluate and manage the treatment and prognosis of head and neck tumor patients scientifically. In this context, the American Cancer Society launched the Head and Neck Cancer Survivorship Care Guideline in 2017 and was endorsed by the American Society for Clinical Oncology. This paper mainly discusses the forming process of the guidelines, the main points of the consensus of experts, the guiding role of the guidelines in clinical work and the obstacles and limitations of the guidelines.

Objective:To carry out content analysis of clinical practice guideline recommendations related to physical activity in survivors of colorectal cancer at home and abroad so as to provide a reference for formulating a standardized and personalized physical activity plan for survivors of colorectal cancer.Methods:Clinical practice guidelines related to physical activity in survivors of colorectal cancer were retrieved in Chinese-English databases, guideline websites and professional society websites by computer from 1st, January 2009 to 1st, July 2019. Guideline recommendations were extracted, translated, classified and analyzed on content with the method of content analysis.Results:A total of 7 clinical practice guidelines were included and 26 recommendations on physical activity of survivors of colorectal cancer were extracted. A total of 8-item content on physical activity were analyzed including the safety and benefits of physical activity, assessment before physical activity, amount of physical activity, way of physical activity, intensity, frequency and duration of physical activity, attention of physical activity, contraindications of physical activity and incremental strategy of physical activity.Conclusions:There are many recommendations on the way, amount, frequency, intensity and attention of physical activity. There are inconsistencies between recommendation mentioned frequency and clinical importance, and consistencies between partial recommendations and domestic practice content, and the recom mendations are more diversified than domestic practice content. We should carry out localization for the high level of foreign guideline to explore the evidences suitable for physical activity in survivors of colorectal cancer in China.

The elderly group is a special group of people. More and more studies have found that the related diseases of the elderly may be closely related to the age of intestine. The microbiota in the intestinal microecology participates in body's defense, immunity, nutrition, metabolism, cancer suppression as well as anti-aging. Once age-related diseases occur, the stability and abundance of intestinal microbiota is bound to be disturbed. This article reviews the relationship between intestinal microbiota and age-related diseases so as to provide new ideas and directions for the treatment and nursing care of elderly diseases.

Mismanagement of pain is a burden on individuals, the health care system and the society. Pain is related to a person's life, which seriously affects the patient's physical health and quality of life. This article interprets the main content of Clinical Best Practice Guidelines:Assessment and Management of Pain (Third Edition) published by Registered Nurses' Association of Ontario (RNAO) in 2013, to help clinical nurses get the latest literature of pain assessment and management, so as to improve the level of care and reduce pain in patients. The updated guidelines emphasize that anyone's pain should be recognized and respected, and that individualized pain assessment and management should include relevant biopsycho-social components. In addition, this guideline advocates continuous learning by health care professionals to update knowledge and information on pain assessment and management, and encourages communication among professional teams in order to optimize pain assessment and management.

With the continuous development of health care, people's awareness of health care is gradually enhanced. Pain has become an important part of disease rehabilitation and nursing. The research and evidence of pain assessment and management are increasing year by year. As the most direct assessor and manager of patients' pain, it is particularly important for nurses to identify and effectively manage different types of pain as soon as possible. In this background, the Registered Nurses' Association of Ontario (RNAO) released Clinical Best Practice Guidelines:Assessment and Management of Pain(Third Edition)in 2013. This article mainly introduces the development, application scope, methodology, main content, quality evaluation and subsidiary information of the guide.
