Objective To conduct a systematic search and summary of the relevant evidence regarding the prevention and rehabilitation of radiation-induced trismus in patients with nasopharyngeal carcinoma，and offer recommendations towards the comprehensive prevention and control of trismus in clinical practice. Methods A standardized strategy was employed to search UpToDate，BMJ Best Practice，Cochrane Library，JBI EBP Datebase，GIN，NICE，SIGN，NGC，yimaitong，PubMed，Web of Science，EBSCO，CINAHL，Open Grey，China National Knowledge Infrastructure，Wanfang Medical Network，and VIP database for clinical decisions，guidelines，expert consensuses，systematic reviews，evidence summaries，best practices，and original research. The search time was from the establishment of the databases until March 2023. Results 18 articles were included in total，including 1 best practice，2 evidence summaries，2 clinical decisions，3 guidelines，1 expert consensuses，6 systematic reviews，and 3 original studies. A total of 24 pieces of evidence were summarized in 7 aspects，including multidisciplinary cooperation，identification and prevention of risk factors，standardized assessment，trismus management and functional exercise，nutritional support，health education and follow-up. Conclusion The evidence summarized in this study can provide an evidence-based basis for clinical professionals to develop plans related to the prevention and rehabilitation of trismus in patients with nasopharyngeal carcinoma. When applying the evidence，professionals need to maximize the preventive and rehabilitative effects according to the current status of management of trismus with nasopharyngeal carcinoma in their hospitals and the needs of patients.

Objective To assess the status and analyze the causes of low intake dehydration in elderly patients with cancer at admission，and to provide references for early clinical recognition and prompt intervention. Methods From March 2021 to March 2022，elderly patients with cancer who had been hospitalized within 24 h in a tertiary A hospital in Tianjin were selected by convenience sampling method. The occurrence of low intake dehydration was judged by the calculated plasma osmolality，and the patients were divided into a normal group and a dehydrated group according to the plasma osmolality values，and the influencing factors for the occurrence of low intake dehydration in elderly patients with cancer were screened by logistic regression analysis. Results Among 706 elderly patients with cancer，the incidence of low intake dehydration during admission was 60.91%. Logistic regression analysis showed that comorbid cognitive impairment（OR=2.018），comorbid swallowing disorder（OR=1.611），Barthel score≤60 points（OR=2.572），serum albumin<35 g/L（OR=2.698） and duration of illness>6 months（OR=2.905） were influencing factors of low intake dehydration（P<0.05）. Conclusion Elderly cancer patients who have a high incidence of low intake dehydration on admission and comorbid cognitive impairment，comorbid swallowing disorders，Barthel score≤60 points，serum albumin<35 g/L and duration of illness>6 months are more likely to develop low intake dehydration，and nursing staff should pay close attention to high-risk patients to identify and plan suitable interventions early to reduce the incidence of low intake dehydration.

To summarize the clinical nursing experience of 3 children with high flow fistula of digestive tract who underwent gastric fluid,bile fluid and intestinal fluid reinfusion combined with relay-type nutritional support. The key points of nursing include：nutritional risk screening and assessment,implementation of relay nutritional support treatment,enteral nutrition combined with digestive fluid reinfusion,fistula management and humanistic care for children and their parents. After careful treatment and nursing care,the weight of the 3 children increased steadily and their nutritional status improved gradually. All of them recovered and were discharged from hospital smoothly.

Objective To explore the effect of motivational interview intervention based on self-efficacy theory on caregivers of children with enterostomy.Methods According to literature research and previous studies,motivational interview program was formulated,which included designing motivational interview strategy,screening and training for interviewing nurses. Seventy-two caregivers of children with enterostomy were randomly divided into two groups by using digital random table method with 36 cases in the experimental group and 36 cases in the control group. Five motivational interviews were conducted in the experimental group on the basis of routine health education and follow-up during hospitalization and 1,2,3 months after discharge;while the control group only received routine health education and follow-up. Self-efficacy scores,anxiety levels and complications related to stoma were compared between two groups at 1,2,3 month after discharge.Results After 3 months of intervention,self-efficacy scores of caregivers in the experimental group were higher than the control group,and the anxiety level was lower than the control group（P<0.05）. The incidence of peristomal dermatitis in the experimental group was significantly lower than the control group（P<0.05）.Conclusion Motivational interview intervention can improve self-efficacy level of caregivers of children with enterostomy,reduce their anxiety level,and reduce the incidence of peristomal dermatitis in children with enterostomy.
