Objective:To summarize the application of digital health technology in swallowing rehabilitation for patients with head and neck neoplasms.Methods:Following the scoping review framework of Arksey and O'Malley, literature on the application of digital health technology in swallowing rehabilitation for patients with head and neck neoplasms was electronically retrieved from databases including the Cochrane Library, Embase, PubMed, Web of Science, CINAHL, IEEE Xplore, China Biology Medicine disc, Wanfang Data, and China National Knowledge Infrastructure. The search period was from database establishment to August 5, 2025.Results:A total of 21 articles were included. Types of head and neck neoplasms included oropharyngeal cancer, nasopharyngeal cancer, oral cancer, tongue cancer, laryngeal cancer, hypopharyngeal cancer, and others. The application forms of digital health technologies involved virtual reality technology, telemedicine systems, interactive mobile health APPs/digital health platforms, and wearable devices. Interactive mobile health apps/digital health platforms were currently the most widely adopted form, with some applications integrating wearable devices for physiological data monitoring. The main components of the intervention included guiding swallowing training methods, training monitoring/supervision and feedback, swallowing function screening/assessment, and health education.Conclusions:The application of digital health technology in swallowing rehabilitation for patients with head and neck neoplasms is still in its early stages, but its advantages in enhancing rehabilitation accessibility and promoting patient adherence have already begun to emerge. Nevertheless, it also faces challenges such as limited user-friendliness, insufficient personalized feedback, and a lack of humanistic care. It is necessary to further explore and develop personalized, precision-oriented intelligent swallowing rehabilitation systems tailored to the specific needs of swallowing rehabilitation for head and neck cancer patients. High-quality clinical studies should be conducted to validate long-term efficacy, thereby providing intelligent solutions for clinical nursing practices in swallowing rehabilitation for these patients.

Objective: To analyze the implementation status and challenges of sex education in special education schools, so as to provide a scientific basis for formulating effective promotion strategies. Methods: From November 2023 to January 2024, a census survey was conducted among 120 in service teachers from 7 special education schools in Luzhou. The questionnaire covered the current status of sex education in schools, teachers attitudes and knowledge toward sex education, and their coping methods for students inappropriate sexual behaviors. Results: About 77.5% of teachers reported having provided sex education to students, but 93.2% indicated a lack of specialized sex education textbooks for special children, 90.4% reported no full time teachers for sex education, and the methods of sex education were relatively limited (50.0% mainly based on lecture method). Nearly 95.8% of teachers held a positive attitude toward sex education, with 98.3% supporting its implementation. Only 26.7% of teachers demonstrated a good grasp of sex education knowledge, with the best understood topic being "recognition and protection of private parts" (21.6%). When dealing with students inappropriate sexual behaviors, the active response rate of teachers was 23.9%, with the highest active response rate observed for "intentionally hugging or kissing the opposite sex" (39.7%). Conclusions The special education schools in Luzhou lack comprehensive sex education curricula, teaching materials and full time teachers, sufficient knowledge among teachers, and adequate proactive responses to students inappropriate sexual behaviors. Greater emphasis should be placed on sex education for special children, including the training of dedicated teachers, to provide comprehensive and high quality sex education services for special children.

OBJECTIVE To explore the potential mechanism of ketamine-induced cognitive impairment in mice based on metabolomics.METHODS Male C57BL/6 mice were randomly divided into control group and ketamine group(25 mg/kg),with 12 mice in each group.Each group of mice was intraperitoneally injected with normal saline or corresponding drugs,4 times a day,for 10 consecutive days.On the last 2 days of drug administration,the cognitive behavior was evaluated by Y maze and novel object recognition test,and the histopathological changes in the prefrontal cortex(PFC)were observed.Ultra-high performance liquid chromatography-tandem mass spectrometry technology was used to analyze the changes of metabolites in PFC,screen for differential metabolites,and perform pathway enrichment analysis.RESULTS Compared with the control group,the morphology of PFC neurons in the ketamine group of mice was inconsistent.There were cavities around the nucleus,and the number of deeply stained cells increased.The mean optical density value of the Nissl staining positive area was significantly reduced,and the alternation rate and discrimination index were significantly reduced(P＜0.05 or P＜0.01).In the PFC tissue samples of mice of the two groups,there were a total of 114 differential metabolites,including 73 up-regulated and 41 down-regulated metabolites,including glutamine,succinic acid,ketoglutarate,and choline,etc.The differential metabolites mentioned above were mainly enriched in metabolism of alanine,aspartate and glutamate,metabolism of arginine and proline,γ aminobutyric acid synapses,pyrimidine metabolism,cholinergic synapses pathways,etc.CONCLUSIONS Ketamine can induce cognitive impairment in mice.Its neurotoxicity is related to abnormal synaptic transmission and energy metabolism,and neuroimmune regulation disorders.

Objective By studying the changes in the institutional distribution of curative care expenditure(CCE)of the elderly population before and after the comprehensive reform medical-pharmaceutical separation and linkage of medical consumption,it provided data reference for the next step of accurately optimizing the elderly patients flow.Methods A multi-stage stratified whole-group sampling survey was used to select the sample.A System of Health Accounts 2011 was used to calculate the CCE of elderly patients in medical institutions.Results The CCE of medical institutions for the elderly population in Beijing increased from 60.457 billion yuan to 797.54 billion yuan,with an average annual growth rate of 6.83%,the fastest growth rate of 24.04%for community-based health treat-ment center.The percentage of CCE in the community increased from 11.31%to 17.71%,while the percentage of CCE in tertiary hospitals decreased by 4.39 percentage points.The flow of CCE for outpatient patients was obviously opti-mized.Younger elderly outpatient patients are more willing to seek treatment in the community,but the flow di-rection of outpatient treatment for elderly patients is more optimized.The CCE fpr elderly outpatient patients with chronic diseases such as endocrine,nutritional and metabolic diseases and nervous system diseases have been substantially transferred to the community-based health center.Conclusion The reform has different impacts on the treatment of elderly patients with different genders,ages and diseases.It is necessary to strengthen the service capacity building of primary medical institutions,highlight the development characteristics of secondary hospitals,and accurately improve the hierarchical diagnosis and treatment system for elderly patients.

Objective To analyze the risk factors of repeated admissions for community-acquired pneumonia(CAP)in adults,and to build a nomogram model to predict individual risk.Methods A total of 2 306 adult hospitalized patients with CAP in Beijing Shijitan Hospital affiliated to Capital Medical University from January 2018 to Decem-ber 2020 were retrospectively selected and divided into repeated admission group and control group according to whether they were readmitted within one year after discharge.Univariate logistic analysis and multivariate logistic a-nalysis were used to determine the risk factors.The risk factors were introduced into R 3.5.3 software to construct the nomogram prediction model.The calibration curve was drawn and the Hosmer-Lemeshow goodness of fit test was performed to evaluate the accuracy of the nomogram prediction model.The receiver operating characteristic(ROC)curve was drawn to evaluate the discrimination of the nomogram prediction model.The decision analysis curve was drawn to measure patient benefits.Results The age,gender,length of stay,total score of comorbidity index,use of special grade antibiotics,history of blood transfusion,and Vaccination history were risk factors of repeated hospi-tal admissions for CAP in adults.The nomogram prediction model of adult CAP repeated admission was constructed based on the above risk factors.The Hosmer-Lemeshow goodness of fit test showed that the fitting effect of the no-mogram prediction model was good(x2=8.873,P=0.353).The ROC curve analysis showed that the area under the curve of the test dataset was 0.775.The results of the decision analysis curve showed that when the threshold was 0.21,the model could generate a net profit of 0.104.Conclusion The nomogram model established in this study has good discrimination and accuracy in predicting the risk of adult CAP repeated admissions and has high clinical application value.

Objective : To evaluate the clinical effect of enamel matrix derivative(EMD) assisted with connective tissue graft(CTG) in the treatment of gingival recession. Methods : Search The Cochrane Library, PubMed, EMbase, Web of Science, Wanfang Public Database,VIP database and CNKI to search for randomized controlled trials of EMD in the treatment of gingival recession. The search period is from the establishment of the databases to October 3, 2022. The test group was treated with EMD+CTG, while the control group was treated with CTG alone. Meta-analyses were performed using Review Manager 5.4.1 and Stat12.0. Results: Meta analysis results showed that only 12 months after treatment, there was a statistically significant difference in the PD and CAL outcome indicators between the EMD assisted treatment group and the control group [MDPD=-0.10, 95% CI (-0.19, -0.01), P = 0.03], [MDCAL=-0.38, 95% CI(-0.71, -0.04), P = 0.03]. There was no significant difference between the test group and the control group in other indicators. Conclusion EMD assisted CTG in the treatment of gingival recession may be beneficial to the reduction of PD and CAL.
