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.

ObjectiveTo explore the data standard system of electronic medical records in the field of rehabilitation, focusing on the terminology and coding standards, data structure, and key content categories of rehabilitation electronic medical records. MethodsBased on the Administrative Norms for the Application of Electronic Medical Records issued by the National Health Commission of China, the electronic medical record standard architecture issued by the International Organization for Standardization and Health Level Seven (HL7), the framework of the World Health Organization Family of International Classifications (WHO-FICs), Basic Architecture and Data Standards of Electronic Medical Records, Basic Data Set of Electronic Medical Records, and Specifications for Sharing Documents of Electronic Medical Records, the study constructed and organized the data structure, content, and data standards of rehabilitation electronic medical records. ResultsThe data structure of rehabilitation electronic medical records should strictly follow the structure of electronic medical records, including four levels (clinical document, document section, data set and data element) and four major content areas (basic information, diagnostic information, intervention information and cost information). Rehabilitation electronic medical records further integrated information related to rehabilitation needs and characteristics, emphasizing rehabilitation treatment, into clinical information. By fully applying the WHO-FICs reference classifications, rehabilitation electronic medical records could establish a standardized framework, diagnostic criteria, functional description tools, coding tools and terminology index tools for the coding, indexing, functional description, and analysis and interpretation of diseases and health problems. The study elaborated on the data structure and content categories of rehabilitation electronic medical records in four major categories, refined the granularity of reporting rehabilitation content in electronic medical records, and provided detailed data reporting guidance for rehabilitation electronic medical records. ConclusionThe standardization of rehabilitation electronic medical records is significant for improving the quality of rehabilitation medical services and promoting the rehabilitation process of patients. The development of rehabilitation electronic medical records must be based on the national and international standards. Under the general electronic medical records data structure and standards, a rehabilitation electronic medical records data system should be constructed which incorporates core data such as disease diagnosis, functional description and assessment, and rehabilitation interventions. The standardized rehabilitation electronic medical records scheme constructed in this study can support the improvement of standardization of rehabilitation electronic medical records data information.

ObjectiveTo analyze the data structure and standards of rehabilitation outpatient medical records, to provide data support for improving the quality of rehabilitation outpatient care and developing medical insurance payment policies. MethodsBased on the normative documents issued by the National Health Commission, Basic Standards for Medical Record Writing and Standards for Electronic Medical Record Sharing Documents, in accordance with the Quality Management Regulations for Outpatient (Emergency) Diagnosis and Treatment Information Pages (Trial), reference to the framework of the World Health Organization Family of International Classifications (WHO-FICs), the data framework and content of rehabilitation outpatient medical records were determined, and the data standards were discussed. ResultsThis study constructed a data framework for rehabilitation outpatient medical records, including four main components: patient basic information, visit process information, diagnosis and treatment information, and cost information. Three major reference classifications of WHO-FICs, International Classification of Diseases, International Classification of Functioning, Disability and Health, and International Classification of Health Interventions,were used to establish diagnostic standards and standardized terminology, as well as coding disease diagnosis, functional description, functional assessment, and rehabilitation interventions, to improve the quality of data reporting, and level of quality control in rehabilitation. ConclusionThe structuring and standardization of rehabilitation outpatient medical records are the foundation for sharing of rehabilitation data. The using of the three major classifications of WHO-FICs is valuable for the terminology and coding of disease diagnosis, functional description and assessment, and intervention in rehabilitation outpatient medical records, which is significant for sharing and interconnectivity of rehabilitation outpatient data, as well as for optimizing the quality and safety of rehabilitation medical services.

ObjectiveTo explore the standardization of inpatient rehabilitation medical record summary sheet, encompassing its structure, content and data standards, to enhance the standardization level of inpatient rehabilitation medical record summary sheet, improve data reporting quality, and provide accurate data support for medical insurance payment, hospital performance evaluation, and rehabilitation discipline evaluation. MethodsBased on the relevant specifications of the National Health Commission's Basic Norms for Medical Record Writing, Specifications for Sharing Documents of Electronic Medical Records, and Quality Management and Control Indicators for Inpatient Medical Record Summary Sheet (2016 Edition), this study analyzed the structure and content of the inpatient rehabilitation medical record summary sheet. The study systematically applied the three major reference classifications of the World Health Organization Family of International Classifications, International Classification of Diseases (ICD-10/ICD-11, ICD-9-CM-3), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Interventions (ICHI Beta-3), for disease diagnosis, functional description and assessment, and rehabilitation intervention, forming a standardized terminology system and coding methods. ResultsThe inpatient rehabilitation medical record summary sheet covered four major sections: inpatient information, hospitalization information, diagnosis and treatment information, and cost information. ICD-10/ICD-11 were the standards and coding tools for admission and discharge diagnoses in the inpatient rehabilitation medical record summary sheet. The three functional assessment tools recommended by ICD-11, the 36-item version of World Health Organization Disability Assessment Schedule 2.0, Brief Model Disability Survey and Generic Functioning domains, as well as ICF, were used for rehabilitation functioning assessment and the coding of outcomes. ICHI Beta-3 and ICD-9-CM-3 were used for coding surgical procedures and operations in the medical record summary sheet, and also for coding rehabilitation intervention items. ConclusionThe inpatient rehabilitation medical record summary sheet is a summary of the relevant content of the rehabilitation medical record and a tool for reporting inpatient rehabilitation data. It needs to be refined and optimized according to the characteristics of rehabilitation, with necessary data supplemented. The application of ICD-11/ICD-10, ICF and ICHI Beta-3/ICD-9-CM-3 classification standards would comprehensively promote the accuracy of inpatient diagnosis of diseases and functions. Based on ICD-11 and ICF, relevant functional assessment result data would be added, and ICHI Beta-3/ICD-9-CM-3 should be used to code rehabilitation interventions. Improving the quality of rehabilitation medical records and inpatient rehabilitation medical record summary sheet is an important part of rehabilitation quality control, and also lays an evidence-based data foundation for the analysis and application of inpatient rehabilitation medical record summary sheet.

To investigate the potential protective effect of thalidomide (THD) on diabetic nephropathy (DN) and its underlying mechanisms. Twenty-four C57BL/6J mice were randomly divided into control, DN and DN+THD200 groups by random number table method. The DN mouse model was established via intraperitoneal injection of streptozotocin. The DN+THD200 group received THD treatment (200 mg·kg -1·d -1) for 8 weeks. Blood and urine biochemical parameters, as well as renal histopathological changes, were compared among the three groups. For in vitro experiments, a high glucose (HG)-induced injury model was established in mouse glomerular podocytes (MPC5). Cells were divided into control (NG), HG, HG+DMSO, HG+THD100 (100 μg/ml), and HG+THD200 (200 μg/ml) groups. THD-treated cells were exposed to THD for 24 h. Western blotting and real-time quantitative PCR were performed to respectively detect protein and mRNA expression levels of ferroptosis-related molecules, including nuclear factor erythroid 2-related factor 2 (NRF2), heme oxygenase 1 (HO-1), and glutathione peroxidase 4 (GPX4). Immunofluorescence was used to evaluate the expression of solute carrier family 7 member 11 (SLC7A11) and 4-hydroxynonenal (4-HNE). The results showed that, compared with control group, DN group exhibited significantly lower blood urea nitrogen, serum creatinine and 24 h urinary albumin levels (all P<0.05). Compared with DN group, DN+THD200 group exhibited significantly lower blood urea nitrogen, serum creatinine and 24 h urinary albumin levels (all P<0.05). Histopathological examination revealed glomerular expansion, mesangial widening, and basement membrane thickening in DN group compared to control group, which were markedly ameliorated by THD treatment. In vitro, HG group showed significantly decreased protein and mRNA expression levels of GPX4, NRF2 and HO-1 compared to NG group. Both HG+THD100 and HG+THD200 groups exhibited upregulated expression levels of these proteins and corresponding mRNA compared to HG group (all P<0.05). Immunofluorescence demonstrated HG group had enhanced 4-HNE fluorescence intensity and reduced SLC7A11 fluorescence intensity, which were reversed by THD treatment. THD alleviates renal injury in DN mice and mitigates HG-induced ferroptosis in MPC5 cells, potentially via activation of NRF2-HO-1-GPX4 signaling pathway.

Objective:This study aimed to analyze the genetic variation of the human papillomavirus (HPV) type 39 genomes and to predict and screen the dominant T-cell and B-cell epitopes of the viral early proteins (E1, E2, E6, E7) and late proteins (L1, L2).Methods:A total of 70 full-length sequences of HPV39 variants were retrieved from the clinical samples and the National Center for Biotechnology Information (NCBI) to construct a phylogenetic tree, analyze genetic polymorphisms, and predict the physicochemical properties of the viral proteins. Next, T-cell and B-cell epitopes were predicted using IEDB and ABCpred, and potential dominant epitopes were further selected based on parameters such as the secondary structure of the epitope region, peptide flexibility, hydrophilicity, surface accessibility and antigenicity. Finally, a homology analysis of the potential dominant epitopes was performed with 12 high-risk HPV types.Results:HPV39 variants from different sources can be clustered into two lineages (A and B), each exhibiting distinct mutation patterns. The mutation rate was the highest in E7 and the lowest in E1 among the different viral genes. However, these nucleotide/amino acid mutations did not significantly impact the physicochemical properties of the viral proteins. After prediction and screening, 5 and 6 potential dominant B-cell epitopes were identified in both L1 and L2, respectively. E1, E2, E6, and E7 yielded 18, 10, 4, and 1 potential dominant HLA-I restricted T-cell epitopes, respectively. Additionally, E1, E2, and E6 yielded 7, 3, and 2 potential dominant HLA-II restricted T-cell epitopes, respectively. Homology analysis indicated that T-cell dominant epitopes in E1, E2, and E6, as well as B-cell epitopes in L2, showed high homology (93%-100%) with HPV68, HPV33, HPV45, and HPV59.Conclusions:Bioinformatics analysis and prediction revealed that HPV39 variants can be clustered into two main evolutionary branches, A and B, each exhibiting a specific mutation pattern. The viral proteins contain potential dominant T-cell and B-cell epitopes that can be further investigated, providing valuable theoretical support for the development of HPV39-related peptide-based vaccines and therapeutics.

Objective To explore the effectiveness and safety of polyglycolic acid(PGA)and hydroxypropyl methylcellulose(HPMC)composite materials for suturing after canine sleeve gastrectomy.Methods A total of 36 healthy Beagle dogs were randomly divided into experimental group and control group in a 1∶1 male-to-female ratio.The experimental group underwent gastric sleeve resection with PGA+HPMC composite material for suture reinforcement,while the control group used NV-ET-M60E-2 suture material.Postoperative monitoring included survival status,food intake,and body temperature changes.Venous blood samples were collected before surgery,3 days after surgery,and before euthanasia for routine blood tests.At 2,4,and 8 weeks postoperatively,six dogs were euthanized at each time point for histological examination,hard tissue pathological evaluation,and safety assessment of the heart,liver,spleen,lungs,and kidneys.Results There were no significant differences in blood routine test results between the control group and the experimental group(P＞0.05).Before dissection,the percentage of basophils was significantly higher in the control group than in the experimental group(P=0.015).At 2 weeks after surgery,the severity of liver cell edema in the control group was higher than in the experimental group(P=0.036).However,the two groups did not significantly differ in the histological examination results of the heart,liver,spleen,lungs,or kidneys at other time points(P＞0.05).Hard tissue pathological slice results at 2,4,and 8 weeks after surgery showed no material residue in either group by the 8th week,and there were no significant differences in inflammation and necrosis scores or fibrosis/fat infiltration totals between the two groups(P＞0.05).Inflammation scores and fibrosis/fat infiltration totals at 8 weeks post-operation were significantly lower than those at 2 weeks post-operation(P＜0.05).During the experiment,no near-death phenomena occurred in either group,and no fever or refusal to eat was observed within 3 days after surgery.At dissection,the Beagle dogs appeared normal with glossy fur and no abnormal secretions.Conclusion PGA+HPMC composite materials can be effectively degraded and used as non-toxic suture fixation materials for wound suturing after sleeve gastrectomy,providing a theoretical basis for their clinical application.

Objective:This study aimed to compare postoperative pain between minimally invasive coronary artery bypass grafting (MICS-CABG) and conventional CABG for multivessel coronary artery disease, comparing baseline characteristics and perioperative data between the two groups, and analyzing risk factors influencing postoperative pain.Methods:A total of 545 patients undergoing elective off-pump coronary artery bypass grafting (OPCABG) for multivessel coronary artery disease at Beijing Anzhen Hospital from July 2022 to July 2023 were included. There were 397 patients in the conventional CABG group (289 males, 108 females, aged 35-77 years) and 148 patients in the minimally invasive CABG group (121 males, 27 females, aged 37-84 years), with 148 patients in each group after propensity score matching. Pain levels were assessed using the Numeric Rating Scale (NRS) at the first 5 days postoperatively (acute postoperative pain, APP) and at 3, 6, and 12 months postoperatively (chronic post-surgical pain, CPSP). Logistic regression was used to analyze risk factors for CPSP at 3 months postoperatively in both groups. Results:Within 48 hours postoperatively, both groups reported maximum NRS pain intensities at rest (NRS 4.0 vs. 6.0) and during activity (NRS 5.2 vs. 7.5). From the third day after surgery, there were no significant differences in resting pain intensity between the two groups, and from the fourth day after surgery, there were no significant differences in pain intensity during movement. With 60.2% in the conventional group and 92.6% in the minimally invasive group experiencing moderate to severe pain at rest (NRS ≥ 4), and 83.5% in the conventional group and 98.0% in the minimally invasive group experiencing moderate to severe pain during activity (NRS ≥ 4). Immediately after drain removal, there was a significant reduction in pain intensity at rest in the minimally invasive group (pre-drain removal NRS 6.0 vs. post-drain removal NRS 2.7), compared to the conventional group (pre-drain removal NRS 4.0 vs. post-drain removal NRS 2.3). However, there was no significant difference in the reduction of pain intensity during activity between the minimally invasive group (pre-drain removal NRS 7.5 vs. post-drain removal NRS 4.2) and the conventional group (pre-drain removal NRS 6.0 vs. post-drain removal NRS 2.7). At 3 months postoperatively, the incidence of CPSP was 35.9% in the conventional group and 35.1% in the minimally invasive group. At 6 months postoperatively, the incidence of CPSP was significantly lower compared to 3 months in both groups (conventional group 8.7% vs. minimally invasive group 6.8%, P<0.001). In the conventional group, higher Europe SCORE Ⅱ was identified as an independent risk factor for CPSP at 3 months postoperatively, while in the minimally invasive group, higher BMI and postoperative use of flurbiprofen for rescue analgesia were identified as independent risk factors. Conclusion:In patients undergoing minimally invasive coronary artery bypass grafting (CABG), the early postoperative acute pain intensity and incidence were higher than those in the conventional CABG group. After drain removal, there were no significant differences in resting pain intensity between the two groups, but pain intensity during movement remained higher in the minimally invasive group compared to the conventional group. The incidence of chronic pain did not differ between the two groups but decreased significantly from 3 months postoperatively. Conventional CABG patients with high preoperative Europe SCORE Ⅱ scores, high preoperative BMI and severe postoperative acute pain tend to have more chronic pain after minimally invasive bypass surgery.
