ObjectiveTo investigate the demand and the application outcomes of case-based learning (CBL) combined with teaching case library in continuing education courses for rehabilitation therapists. MethodsA convergent mixed-methods research design was adopted, involving 51 rehabilitation therapists and 31 instructors who participated in the advanced training program at the Department of Rehabilitation Medicine, Peking University Third Hospital between October, 2022 and October, 2024. Self-developed questionnaires were used to collect data on the perceived needs of teachers and students regarding CBL and teaching case library. Differences between CBL + teaching case library and traditional lecturing in student evaluations, classroom participation and interaction were compared using Student Evaluation of Teaching in Medical Lectures, Classroom Participation Scale and Flanders Interaction Analysis System. Semi-structured interviews were conducted to obtain evaluations and attitudes towards this method from both instructors and students' perspectives. ResultsThe survey showed that 91.4% of participating teachers and students supported the use of CBL in the courses, and 82.7% advocated that the teaching case library should include typical cases. Significant differences were observed in teaching preference between teachers and students (χ² = 17.597, P < 0.01). Application effects demonstrated that CBL+teaching library significantly outperformed traditional teaching methods in student previewing behaviors, classroom interaction and learning outcomes (|Z| ≥ 2.646, P < 0.01). Flanders Interaction Analysis indicated that CBL+teaching library was superior to traditional teaching in terms of students' motivation to speak and autonomous learning. Qualitative Research generated four positive themes including cultivating clinical reasoning, being close to clinical practice, deepening knowledge understanding and improving teaching quality; and three negative themes including increasing teaching burden, high software and hardware requirements and posing great challenges to students were generated. ConclusionCompared with traditional teaching methods, CBL combined with teaching case library is closely linked to clinical practice, facilitating students' clinical reasoning, enhancing teaching effectiveness and satisfaction, and therefore aligning with the goals and needs of continuing education for rehabilitation therapists, which is highly recognized by both instructors and students.

Objective:To assess the nutritional status and risk of children with cyclic vomiting syndrome（CVS）and to provide a clinical evidence for nutritional support.Methods:A total of 160 children diagnosed with CVS and 160 healthy controls were prospectively enrolled in the study，who were admitted to Beijing Tsinghua Changgung Hospital from April 2021 to February 2024.Nutritional status was assessed by anthropometric indices（height，weight，and body mass index），and it was expressed in standard deviation score（Z score）.Nutritional risk screening tool STRONGkids was applied to nutritional risk screening，and the laboratory assessment（albumin，pre-albumin，hemoglobin，urea nitrogen and creatinine）were measured.Results:Among the 160 cases，there were 73 males and 87 females，including 18 cases of mild seizures and 142 cases of moderate and severe seizures，with the average onset age of（47.54±2.96）months and an average diagnosis age of（74.89±3.68）months.The average duration from the first attack to diagnosis was（27.35±2.36）months，and the average course of the disease was（41.35±2.63）months.The malnutrition rate of children in CVS was 36.9%（59/160），of which 18.1%（29/160）was severely malnourished.There was a statistically significant difference in the weight-for-age Z-score（WAZ），height-for-age Z-score（HAZ），and body mass index-for-age Z-score（BAZ）between the CVS group and the control group（ P<0.001）.We found a statistically significant difference in laboratory indicators（albumin，pre-albumin，hemoglobin，urea nitrogen and creatinine）between the two groups（all P<0.001）and hemoglobin was positively correlated with WAZ，HAZ and BAZ（ r=0.346,0.250,0.277，all P<0.01）.Using the STRONGkids nutritional risk screening tool，there were 43 cases with moderate nutritional risk and 117 cases with high nutritional risk，and children with high nutritional risk were likely to have lower WAZ，HAZ and BAZ than the children with moderate nutritional risk，and there was a significant difference in WAZ，HAZ，BAZ，hemoglobin，and creatinine between the two groups（ P<0.05）.And there was a correlation between the degree of CVS attack and nutritional risk grouping（ r=0.543， P<0.001）. Conclusion:Children with CVS have a high incidence of malnutrition，and the serum albumin，prealbumin，hemoglobin，urea nitrogen and creatinine levels are of great value for nutritional assessment.The STRONGkids score method helps to evaluate nutritional risk in children with CVS.

Objective:To investigate the characteristics of gut microbiota distribution in children with cyclic vomiting syndrome（CVS）complicated by constipation.Methods:The children with CVS, aged from 1 to 16 years, who were admitted to Beijing Tsinghua Changgung Hospital from June 2022 to January 2024, were divided into constipation group and normal group(non-constipation group) according to whether they were complicated with constipation or not.The clinical data and stool samples of children were collect. The abundance, diversity and composition of intestinal flora in fecal samples of two groups were detected by metagenomics sequencing.Results:A total of 20 children with CVS were collected, including 10 patients in constipation group and 10 patients in normal group.There were no significant differences in general demographic data between the two groups, including age at admission, age at first onset, body mass index, gender distribution, disease severity, endoscopic findings, and abdominal pain patterns.Microbiome analysis yielded 470 operational taxonomic units (OTUs), with 414 OTUs identified in normal group and 56 OTUs in constipation group. The abundance and diversity of intestinal flora in constipation group were significantly lower than those in normal group. Principal coordinate analysis and principal component analysis indicated significant structural differences in gut microbiota composition between the two groups. LEfSe analysis revealed distinct taxonomic patterns between the two groups, with the normal group demonstrating predominant representation of Firmicutes at the phylum level, while the constipation group showed higher relative abundance of Bacteroidetes and Actinobacteria. KEGG pathway analysis revealed that the carbon metabolism pathways was significantly enriched in the constipation group.Conclusion:There are significant differences in intestinal flora between CVS children with and without comorbid constipation.Bacteroides and Actinomycetes play an important role in constipation of children with CVS. The diversity and metabolic function of intestinal flora may be one of the pathological mechanisms of CVS complicated with constipation.

Objective:To evaluate the efficacy of combined cricopharyngeal myotomy (CPM) and autologous fat injection laryngoplasty (AFIL) in the management of dysphagia secondary to glossopharyngeal and vagal nerve injury.Methods:This retrospective cohort study collected the clinical data of 18 patients with persistent dysphagia due to glossopharyngeal and vagus nerve injuries, who underwent concurrent cricopharyngeal myotomy (CPM) and autologous fat injection laryngoplasty (AFIL) at the Department of Otolaryngology, Peking Union Medical College Hospital, from January 2017 to December 2024. Pre-and postoperative assessments included electronic flexible laryngoscope, the Chinese version of Swallow Quality-of-Life Questionnaire (CSWAL-QOL), videofluoroscopic swallowing study (VFSS), body weight changes, and nasogastric tube (NGT) removal status with routine follow-up. The comparison of swallowing function before and after surgery was conducted using paired samples t-test and χ2 test. Results:The study cohort comprised 10 male and 8 female patients, with ages ranging from 33 to 70 years (mean±SD: 53.8±10.5). All surgical procedures were completed successfully without complications. During the 6-to 24-month follow-up period, 10 of the 13 patients who were initially nasogastric tube-dependent achieved successful decannulation. Compared with preoperative values, postoperative measurements demonstrated statistically significant improvements across all parameters: mean body weight increased from (56.95±9.14) kg to (59.22±8.72) kg ( t=3.689 , P<0.01), CSWAL-QOL scores improved from 91.89±17.81 to 130.83±25.42 ( t=6.921 , P<0.01), while, both VFSS scales showed marked reductions (VFSS-SWAL: 6.78±1.40 to 3.39±1.61, t=-8.001, P<0.01; PAS: 6.56±1.15 to 2.94±1.26, t=-10.114, P<0.01). Conclusions:Combined CPM and AFIL represents an effective surgical approach for dysphagia following glossopharyngeal and vagal nerve injury, thereby demonstrating significant improvements in both swallowing function and quality of life.

To investigate the feasibility and advantages of "Axis Coordinate Localization Method" combined with total endoscopic technique for parotid surgery. A total of 31 patients with parotid gland tumors who were admitted to the First Affiliated Hospital of Zhengzhou University from January 2022 to August 2024 were included in this study. The cohort comprised 11 males and 20 females, with age of (38.9±13.9) years and a maximum tumor diameter of (19.34±6.89) mm. Among these cases, 93.5% (29/31) involved the superficial lobe and 6.5%(2/31) the deep lobe of the parotid gland. The "axial" localization method was utilized to plan the surgical approach: establishing a coordinate system with the earlobe as the origin, the surface projection of the parotid duct as the x-axis, and a perpendicular line through the origin as the y-axis. The incision type-pre-tragal, retroauricular groove, or postauricular hairline-was selected according to the position of the tumor′s surface projection center within this coordinate system. All operations were performed using a complete endoscopic technique for tumor and glandular tissue resection. Postoperative facial nerve function was assessed with the House-Brackmann grading scale, while patient incision satisfaction, impact on work and daily life, and facial symmetry were quantitatively evaluated using a Numerical Rating Scale (10-point system).　All 31 patients successfully underwent the procedure. Short-term postoperative complications included temporary facial paralysis in 1 case (3.2%), periauricular numbness in 1 case (3.2%), surgical site effusion in 1 case (3.2%), and subcutaneous hematoma in 1 case (3.2%). All complications resolved after appropriate management. During follow-up, there were no instances of sialocele, Frey syndrome, incision infection, or tumor recurrence. Patient ratings were as follows: incision satisfaction (9.42±0.78), impact of surgery on daily life (1.32±0.60), and facial symmetry (9.29±0.78). The one case of temporary facial paralysis recovered 3 months after surgery. The combination of the "Axial" localization method and fully endoscopic technique demonstrates clear clinical feasibility in parotid tumor resection. This approach enables rapid and personalized incision selection based on tumor location, while the endoscopic minimally invasive technique reduces tissue trauma, improves cosmetic outcomes, and enhances surgical safety. It provides a new minimally invasive treatment pathway for patients with benign parotid tumors.

ObjectiveTo elucidate the critical role of rehabilitation medical records (including electronic records) in rehabilitation medicine's clinical practice and management, comprehensively analyzed the structure, core content and data standards of rehabilitation medical records, to develop a standardized medical record data architecture and core dataset suitable for rehabilitation medicine and to explore the application of rehabilitation data in performance evaluation and payment. MethodsBased on the regulatory documents Basic Specifications for Medical Record Writing and Basic Specifications for Electronic Medical Records (Trial) issued by National Health Commission of China, and referencing the World Health Organization (WHO) Family of International Classifications (WHO-FICs) classifications, International Classification of Diseases (ICD-10/ICD-11), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Interventions (ICHI Beta-3), this study constructed the data architecture, core content and data standards for rehabilitation medical records. Furthermore, it explored the application of rehabilitation record summary sheets (home page) data in rehabilitation medical statistics and payment methods, including Diagnosis-related Groups (DRG), Diagnosis-Intervention Packet (DIP) and Case Mix Index. ResultsThis study proposed a systematic standard framework for rehabilitation medical records, covering key components such as patient demographics, rehabilitation diagnosis, functional assessment, rehabilitation treatment prescriptions, progress evaluations and discharge summaries. The research analyzed the systematic application methods and data standards of ICD-10/ICD-11, ICF and ICHI Beta-3 in the fields of medical record terminology, coding and assessment. Constructing a standardized data structure and data standards for rehabilitation medical records can significantly improve the quality of data reporting based on the medical record summary sheet, thereby enhancing the quality control of rehabilitation services, effectively supporting the optimization of rehabilitation medical insurance payment mechanisms, and contributing to the establishment of rehabilitation medical performance evaluation and payment based on DRG and DIP. ConclusionStructured rehabilitation records and data standardization are crucial tools for quality control in rehabilitation. Systematically applying the three reference classifications of the WHO-FICs, and aligning with national medical record and electronic health record specifications, facilitate the development of a standardized rehabilitation record architecture and core dataset. Standardizing rehabilitation care pathways based on the ICF methodology, and developing ICF- and ICD-11-based rehabilitation assessment tools, auxiliary diagnostic and therapeutic systems, and supporting terminology and coding systems, can effectively enhance the quality of rehabilitation records and enable interoperability and sharing of rehabilitation data with other medical data, ultimately improving the quality and safety of rehabilitation services.
