目的 构建与验证回肠造口术后造口周围皮炎发生的列线图预测模型。方法 回顾性分析广州市中山大学附属第六医院2022年7月—2023年7月收治的441例回肠造口术患者资料。通过单因素Logistic回归确定影响因素，基于训练队列建立列线图模型，并采用受试者操作特征（ROC）曲线和校准曲线分别评估模型的区分度与校准能力，同时通过决策曲线分析（DCA）评估临床实用性。在内部验证队列进行模型性能验证。结果 单因素Logistic回归确定6个危险因素，最终选取其中5个（是否糖尿病、造口定位、是否接受造口护理宣教、造口皮肤凹陷、性别）构建预测模型。训练队列中，模型校准曲线显示良好拟合优度（Hosmer and Lemeshow检验P = 0.976），ROC曲线下面积为0.672；决策曲线证实模型具有临床应用价值，预测模型在验证集上有类似结果。结论 本研究建立的5参数列线图模型具有良好的区分度、校准能力和临床实用价值，可为造口周围皮炎的预测提供量化工具。

       Objective To establish a predictive nomogram for peristomal dermatitis after ileostomy．Methods This study analyzed 441 patients who underwent ileostomy at a third-class premium hospital．The risk factors of peristomal dermatitis were determined by univariate binary Logistics regression．Then a predictive nomogram was established with the risk factors in the training cohort．The discrimination and calibration ability of the nomogram was demonstrated by receiver operating characteristic curves and calibration curves，respectively．Besides，a testing cohort was utilized to validate the nomogram model．To reflect the clinical utility of the model，we also performed decision curve analysis．Results A total of six parameters was determined as the risk factors of peristomal dermatitis．Finally，five of them（whether diabetes，stoma location，whether to receive stoma care education，stoma skin depression，gender）were chosen to establish the nomogram．The calibration curve showed favorable calibration ability in the training cohort with a Hosmer and Lemeshow goodness of fit test P-value of 0.976 and the area under the curve of the nomogram is 0.672．The decision curve showed nomogram had potential clinical utility．These results were consistent with the testing cohort．Conclusions The nomogram established by five parameters was capable of predicting the occurrence of peristomal dermatitis with favorable discrimination and calibration ability and shows potential clinical utility．

目的 探讨与观察思维导图教育模式对肠造口患者生活质量与心理情绪的影响。方法 选择2021年5月—2022年4月本院胃肠外科收治的低位直肠癌术后患者80例为研究对象,按入院顺序随机编号,对应随机数字为偶数的分到思维导图组（n=40）,奇数的分到传统组（n=40）。传统组给予常规健康教育干预,思维导图组在传统组护理的基础上给予思维导图教育模式干预,思维导图组与传统组护理观察时间为3个月。结果 思维导图组护理期间的造口感染、坏死、水肿、出血、旁疝等并发症发生率与传统组相比都降低（P<0.05）。思维导图组与传统组护理后的焦虑与抑郁评分与护理前相比降低（P<0.05）,护理后思维导图组评分与传统组相比降低（P<0.05）。思维导图组的术后住院时间、术后排气时间、术后下床活动时间与传统组相比均减少（P<0.05）。思维导图组护理后的副作用、共性症状、尿路症状、特异躯体症状、特异心理、性功能、尿袋问题等生活质量评分与传统组相比都减少（P<0.05）。结论 思维导图教育模式在肠造口患者的应用能促进缓解心理负面情绪,促进患者康复,提高患者的生活质量,减少术后造口并发症的发生。

Objective To explore and observe the effects of mind map education mode on the quality of life and psychological emotions of patients with enterostomy．Methods From May 2021 to April 2022, 80 cases of patients with postoperative low rectal cancer who were admitted to the Gastrointestinal Surgery Department of our hospital were selected as the research subjects, and all the cases were numbered according to the random admission sequence, and those with even random numbers were assigned to the mind map group（n=40）, and odd numbers were assigned to the traditional group（n=40）．The traditional group was given routine health education intervention, the mind map group was given mind map education mode intervention additionally, and the nursing observation time of both groups was 3 months．Results The incidences of complications such as stoma bleeding, parastomal hernia, stoma necrosis, stoma edema and stoma infection during nursing in the mind map group were lower than that in the traditional group（P<0.05）．The anxiety and depression scores in both groups after nursing were significantly lower than those before nursing（P<0.05）, and the scores in the mind map group after nursing were also significantly lower than those in the traditional group（P<0.05）．The postoperative hospital stay, postoperative exhaust time, and postoperative ambulation time of the mind map group were significantly shorter than those of the traditional group（P<0.05）．The quality of life scores of common symptoms, side effects, urinary tract symptoms, specific somatic symptoms, specific psychology, urine bag problems and sexual function in the mind map group after nursing were significantly lower than those in the traditional group（P<0.05）．Conclusions The application of mind map education model in patients with enterostomy can promote the relief of psychological negative emotions, promote the recovery of patients, reduce the occurrence of postoperative complications, and improve the quality of life of patients．
