Objective To construct a key nursing technology system for the treatment of patients exposed to nuclear radiation in hospitals，and provide technical guidance and support for emergency nursing rescue in hospitals of nuclear radiation accidents. Methods A research group was composed of a team with rich experience in nuclear radiation accidents. Based on 4 scenarios of nuclear radiation accidents（including external irradiation，internal irradiation，external contamination，internal contamination），the literature search was conducted to form the first draft of the system. Delphi method was used to complete 2 rounds of expert letter consultation，and the final draft of the key nursing technology system for hospital treatment of patients with nuclear radiation exposure was constructed according to the revised opinions of experts. Results A total of 16 experts completed 2 rounds of correspondence. The effective recovery rates were 100% and 80%；the recommendation rates were 65% and 50%；the authority coefficients（Cr） were 0.778 and 0.797；the coefficient of variation（CV） of the 2 rounds of expert letter consultation was≤0.25. Finally，a key nursing technology system for in-hospital treatment of patients with nuclear radiation exposure was formed，including 5 first-level indicators，26 second-level indicators and 74 third-level indicators. Conclusion The constructed key nursing technology system for hospital treatment of patients with nuclear radiation exposure is highly practical and scientific，and it is conducive to the formation of standardized nuclear radiation exposure treatment procedures，and provides a theoretical basis for the training and evaluation of nursing staff related to nuclear radiation exposure.

Objective To analyze the real experiences of patients with inflammatory bowel disease（IBD） during dietary restrictions，providing references for healthcare personnel to guide patients in standardizing dietary restriction behaviors. Methods Purposeful sampling was employed to select 14 patients with IBD who were treated at a tertiary A hospital in Shanghai between October 2022 and February 2023 for semi-structured in-depth interviews. Data were analyzed using the Colaizzi’s 7-step method in phenomenological research. Results 4 themes and 13 sub-themes were extracted. Theme 1：facing multiple physiological challenges（hunger，nutritional imbalance，fatigue and muscle atrophy）. Theme 2：experiencing negative psychological disturbances（craving and struggle for gourmet food，diminished zest for life and increased anxiety，feeling embarrassed during social activities）. Theme 3：adopting various coping strategies（self-adjustment and adaptation to dietary restrictions，satisfying oral desires through various avenues，seeking knowledge and guidance on nutrition）. Theme 4：gaining more growth and support（improved symptom and quality of life，enhanced awareness of dietary health，improved ability to manage diet，receiving support from peers and family）. Conclusion The experience of dietary restrictions in IBD patients is complex and varied. Nursing staff should prioritize nutritional risk screening for IBD patients，pay attention to their mental health，provide patients with scientific and personalized dietary guidance，and strengthen social and family support to assist patients in better self-management of their diet.

Objective To understand the dilemmas experience of adolescents with inflammatory bowel disease （IBD） as they transit towards adulthood，and to provide the basis for the development of patient-centered transition nursing intervention program. Methods With the application of phenomenological research method in qualitative research and purposive sampling method，from September to December 2022，15 adolescents with IBD from the department of gastroenterology in 2 tertiary A hospitals in Shanghai for semi-structured in-depth interview，and the interview data were analyzed by Colaizzi 7-step analysis method. Results 4 themes were extracted. ①Self-coping dilemma，including difficulty in adapting to changes in the medical environment，difficulty in adapting to changes in medical roles，difficulty in coping with negative emotional distress，difficulty in meeting the special needs of daily life. ②Family support dilemma，including heavy family financial burden，excessive participation of family caregivers，and insufficient family resilience. ③Medical assistance dilemma，including limited professional assistance and limited information sharing. ④Social support dilemma，including the limited applicability and accessibility of social support，insufficient social cognition and identity. Conclusion Adolescents with IBD face multiple dilemmas as they move towards adulthood. It is suggested that nursing staff should formulate a perfect personalized transition plan，carry out transition-oriented family health education，improve the medical assistance system，further strengthen social support，and improve the level of transition readiness for the adolescents towards adults.

The transition period from children with inflammatory bowel disease（IBD） to adults is an important stage that affects their long-term quality of life. However,most children with IBD have a low degree of readiness during the transition period,which seriously affects the prognosis and quality of life of children. This paper reviews the research progress on the domestic and foreign status of transition readiness for children with IBD,influencing factors,defects and intervention strategies. Suggestions,shortcomings in current research and practice are put forward,aiming to carry out relevant research for our country in the future and provide references to improve the transition readiness of children with IBD to adults.
