Oral squamous cell carcinoma(OSCC)is a malignant lesion originating from the oral mucosal squamous epithelium,account-ing for over 80％of oral and maxillofacial malignancies.Key etiological factors include tobacco,alcohol abuse,and betel quid chewing.In China,its incidence has shown an overall upward trend,posing a significant threat to public health.OSCC exhibits high local invasive-ness,making early diagnosis critical for improving prognosis.Its clinical management requires close multidisciplinary collaboration among oral and maxillofacial surgery,head and neck surgery,radiation oncology,medical oncology,reconstructive surgery,radiology,patholo-gy,and nutritional support teams.Given the increasing disease burden of OSCC and rapid development of multidisciplinary collaborative models,an expert panel has formulated this integrated management consensus based on evidence-based medicine and extensive deliber-ation.Centered on the'Prevention-Screening-Diagnosis-Treatment-Rehabilitation'framework,the consensus provides comprehensive guidance for the entire disease course of OSCC patients,aiming to standardize clinical practice.

Objective? To evaluate the sleep quality of elderly patients at a ClassⅢ Grade A hospital in Beijing with the Chinese version of Richards-Campbell Sleep Questionnaire (RCSQ) and to assess the reliability and validity of the questionnaire in elderly inpatients. Methods? From October 2017 to July 2018, we selected 155 elderly inpatients at a Class Ⅲ Grade A hospital in Dalian of Liaoning Province by purposive sampling. All of the patients were investigated with the general information questionnaire and the Chinese version of RCSQ. We assessed the test-retest reliability in 30 patients with hospital stay more than one week. Reliability and validity of the questionnaire were tested by the internal consistency, test-retest reliability, split-half reliability and construct validity. Results? The Cronbach's α and split-half reliability of the total questionnaire were 0.898 and 0.837 respectively. The correlation coefficients between items and the total score ranged from 0.805 to 0.909 (P＜0.01). The item correlations of test-retest reliability ranged from 0.362 to 0.884 (P＜0.05) with 0.671 for the correlation in total scores (P＜0.05). Exploratory factor analysis extracted one common factor with 71.541% for the cumulative variance contribution, 0.875 for the KMO value and 460.834 for the Bartlett value (P＜0.01). Confirmatory factor analysis showed that the model fitted well. Conclusions? The Chinese version of RCSQ has good reliability and validity in assessing sleep quality for elderly inpatients which can be an instrument for sleep research or screening in this population.

Objective To test the reliability and validity of the Chinese version of Insomnia Severity Index(ISI-C) in patients with insomnia. Methods One hundred and twenty patients with insomnia were selected from Zhongshan Hospital Affiliated to Dalian University. The subjects had completed the ISI-C scale and Pittsburgh Sleep quality Index(PSQI) scale, Epworth Sleepiness Scale(ESS) at the same time. The reliability and validity of the scale were tested by Cronbach α coefficient, item correlation analysis, exploratory factor analysis and ROC curve test. Results The Cronbach α coefficient of the ISI-C was 0.804,the test-retest reliability was 0.887 (P<0.01). The items of ISI-C scale were correlated with the corresponding items of PSQI (r=0.831, P<0.01), ESS(r =0.218, P<0.05). Two common factors were extracted by factor analysis including the severity of insomnia and the influence of insomnia, and the cumulative contribution rate was 63.117% (P<0.01).When the cutting point was 10.5 points, the sensitivity and specificity were 84.0% and 92.3%, respectively (P<0.01). Conclusions ISI-C scale is a reliable and valid instrument. It can be used to measure the insomnia of patients in hospitals.

Insomnia is the most common sleep disorder, which is common in clinical patients. Effective evaluation is the premise of improving insomnia. This article reviews the common subjective and objective evaluation tools and methods of insomnia, in order to provide reference for medical staff to scientifically evaluate insomnia and formulate corresponding intervention strategies.

Objective To establish a nursing outcome evaluation system for hip replacement patients. Methods The nursing records of 400 hip replacement patients of the orthopedic department of a Class Ⅲ Grade A hospital in Dalian City from January 2015 to January 2017 were reviewed. Based on Nursing Outcomes Classification (Third Edition), the evaluation system for hip replacement patients were constructed combined with literature review, semi-structured interviews and Delphi expert inquiry method was applied to determine the entry content of the system. Results A total of 20 experts were recruited in the consultation. The questionnaire recovery rate of the first round consultation was 85% (17/20), and the second round was 100% (17/17). The expert authority coefficients were 0.839 and 0.850, and the variation coefficient was 0.076 to 0.142. After two rounds of consultation, the experts' opinions reached a good level of consistency. The evaluation system of nursing outcome of hip replacement included 6 dimensions,18 second-level items, and 36 third-level items. Conclusions Based on the nursing outcome, the nursing outcome evaluation scale for hip replacement patients evaluated patients from the perspective of nursing. It is beneficial to enhance the specialized nursing quality in orthopedic department.
