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.

Objective To investigate the value of combining preoperative magnetic resonance imaging(MRI)and postoperative pathological assessment of lymph node metastasis in predicting overall survival in rectal cancer patients.Methods This retrospective study collected clinical,pathological and image information of 2610 patients histopathologically confirmed with rectal adenocarcinoma at the Sixth Affiliated Hospital of Sun Yat-sen University between January 2016 and December 2021.All patients underwent MRI scans and were divided into three groups according to lymph node status assessed by preoperative MRI(MRIN)and postoperative pathology(PN):MRIN+but PN-(MRIN+group),PN+but MRIN-(PN+group),MRIN+and PN+(MRI-PN+group).Inverse probability weighting(IPW)was used to adjust for confounding factors.Kaplan-Meier curves were used to estimate overall survival and log-rank tests were used to compare the difference.Univariate Cox regression models were used to analyze the correlation between tumor characteristics and overall survival,and bidirectional stepwise Cox regression models were used to identify independent risk factors for overall survival.Results The MRI-PN+group showed higher tumor staging,more frequent perineural invasion,more distant metastases,and a higher risk of death compared to the P N+group and MRIN+group(all P＜0.05).Kaplan-Meier curves showed that the 3-year survival rates for the MRIN+group,PN+group,and MRI-PN+group were 90.5%,79.1%,and 76.4%,respectively;the 5-year survival rates were 85.7%,71.5%,and 59.2%,respectively.Stepwise Cox regression showed that age,tumor location,carcino-embryonic antigen,carbohydrate antigen 19-9,lymph nodes number,pathological tumor stage,lymphovascular invasion,perineural invasion,distant metastasis,neoadjuvant therapy and adjuvant therapy,and MRI-pathology lymph node status were independent risk factors for overall survival in rectal cancer(all P＜0.05).Conclusion Evaluating the lymph node status by combining preoperative MRI and postoperative pathology helps predict overall survival in rectal cancer patients more accurately.

OBJECTIVE: To construct cytarabine-resistant acute myeloid leukemia (AML) cell lines, and explore the correlation between Sirt1, PGC-1α expression levels and drug resistance. METHODS: Human acute promyelocytic leukemia Kasumi-1 cells were induced by the method of gradually increasing the concentration of Ara-C drug. The IC₅₀ value of Kasumi-1 cells before and after drug addition was detected by CCK-8 method, so as to construct Ara-C resistant cell lines. The expression levels of Sirt1 and PGC-1α mRNA in Kasumi-1 drug-resistant cell lines and their parental cell lines were detected by real-time fluorescence quantitative PCR, and the expression levels of Sirt1 and PGC-1α protein in kasumi-1 drug-resistant cell lines and their parental cell lines were detected by Western blot. RESULTS: The constructed Kasumi-1 cell line had common morphological characteristics of drug-resistant cell lines under microscope, and the drug resistance index was greater than 5, indicating that Kasumi-1 drug-resistant cells had good drug resistance after the construction. The RT-qPCR and Western blot assays showed that the expression levels of Sirt1 and PGC-1α mRNA and protein in the drug-resistant cell lines were higher than those of the parental cell lines (P<0.001). CONCLUSION AML cell lines resistant to Ara-C can be successfully induced by the method of gradually increasing the concentration, and the co-high expression of Sirt1 and PGC-1α may mediate the drug resistance of AML cells.

Objective:To assess the correlation between frailty and cardiac autonomic nervous system function in elderly patients.Methods:Elderly hospitalized patients aged 65 years and over were enrolled and assessed for frailty by using the clinical frailty scale.Cardiac autonomic modulation was evaluated by heart rate variability analysis through 24 h electrocardiogram recording.Results:A total of 180 elderly patients were enrolled in this study, including 66 patients with frailty and 114 patients without frailty.The mean age of the frailty group was higher than that of the non-frailty group(79.8±6.0 vs.75.0±6.3, t=5.030, P<0.001). The proportions of patients with hypertension, stroke/transient cerebral ischemia attack(TIA), heart failure and osteoarthritis were higher in the frailty group than in the non-frailty group(all P<0.05). Compared with the non-frailty group, the standard deviation of normal-to-normal intervals(SDNN)[103.0(76.0, 121.2) vs.107.5(92.0, 136.0), Z=-2.108, P=0.035], the standard deviation of the averages of NN intervals in all 5-min segments(SDANN)[86.0(67.7, 106.5) vs.97.5(78.0, 126.0), Z=-2.694, P=0.007], normalized low frequency(LFnorm)(53.1±13.0 vs.59.3±13.9, t=-3.024, P=0.003)and low frequency/high frequency(LF/HF)ratio[1.2(1.0, 1.4) vs.1.4(1.1, 1.7), Z=-3.041, P=0.002]were decreased and normalized high frequency(HFnorm)(36.8±9.2 vs.32.2±10.7, t=3.033, P=0.003)was increased in the frailty group.HFnorm in the frailty group was significantly higher than that in the non-frailty group.The incidents of SDANN<92 ms, LFnorm<50 nU, HFnorm>32 nU and LF/HF ratio<1.5 were higher in the frailty group than in the non-frailty group(59.1% or 39/66 vs.41.2% or 47/114, 42.4% or 28/66 vs.22.8% or 26/114, 72.7% or 48/66 vs.49.1% or 56/114, 84.8% or 56/66 vs.65.8% or 75/114, χ2=5.346, 7.660, 9.547, 7.664, P=0.021, 0.006, 0.002, 0.006). Logistic multivariate regression analysis showed that LFnorm, HFnorm and LF/HF ratio were correlated with frailty( OR=0.971, 1.039 and 0.333, all P<0.05), and HFnorm>32 nU and LF/HF ratio<1.5 were risk factors for frailty( OR=2.401 and 2.773, both P<0.05). Conclusions:Cardiac autonomic nerve system function is impaired in elderly frail patients, with the imbalance between the sympathetic and vagus nerves.Therefore particular attention should be paid to heart rate variability in elderly patients with frailty.

Objective:To explore the efficacy and safety of anti-tumor necrosis factor alpha (TNFα) monoclonal antibodies (mAbs) for severe/refractory vasculo-Behcet′s disease (BD).Method:The clinical data of severe/refractory vasculo-BD patients treated with anti-TNFα mAbs were retrospectively analyzed. Response of anti TNFα mAbs was analyzed. The dosage changes of glucocorticoid, the level of erythrocyte sedimentation rate (ESR) and hypersensitive C-reactive protein (hsCRP) before and after treatment were recorded, as well as side effects.Result:Sixteen patients were enrolled. Arterial lesions were reported in 12 patients, including 9 with arterial aneurysm, 6 with arterial dilation, 2 with stenosis and 2 with occlusion. Seven patients presented venous thrombosis, including lower extremity veins ( n=6), cerebral venous sinus ( n=2) and inferior vena cava system ( n=2). Two cases had both arterial and venous involvement. Before the application of TNFα mAbs, all 16 patients failed to response to prednisone or its equivalent dose of 40 (7.5-90) mg/d in combination with cyclophosphamide, methotrexate, thalidomide or azathioprine for median 4 (0-156) months. After a mean duration of treatment for (17.1±6.5) months, 15 patients achieved complete remission and 1 patient achieved partial remission. Three patients received surgery without any postoperative complications. After using anti TNFα mAbs, the dosage of prednisone [5(0-12.5)mg/d vs. 40(7.5-90)mg/d, P<0.01], ESR [(7.3±4.6) mm/1h vs. (33.5±26.7) mm/1h, P<0.01] and hsCRP [1.9(0.2-11.4) mg/L vs. 24.3(0.4-113.9) mg/L, P<0.01] were significantly decreased. Side effects were observed in 2 patients. One developed pulmonary infection 12 months after adalimumab with conventional treatment. Another patient had allergy to infliximab then switched to adalimumab. Conclusion:In combination with corticosteroids and immunosuppressants, anti-TNF α mAbs are effective and well-tolerated in severe/refractory vasculo-BD, with a favorable steroid -sparing effect and rare postoperative complications.

Objective:To assess the cardiac autonomic nervous function in elderly patients with frailty.Methods:Patients aged ≥ 65 years old admitted in Beijing Hospital from September 2018 to August 2019 were enrolled in this study. Clinical frailty score was used to assess the frailty. The cardiac autonomic modulation was evaluated by sinus heart rate turbulence analysis through 24 h electrocardiogram recording.Results:A total of 129 elderly patients were finally enrolled in this study with a mean age of (77.5±6.4) years, 58.1% of them were male. There were 53 patients in frail group and 76 patients in non-frail group. The age of the frailty group was significantly higher than that of the non-frailty group [(80.5±5.5) vs.(75.3±6.2)]; the prevalence of hypertension [84.9%(45/53)], heart failure [32.1%(17/53)] and peripheral vascular diseases [32.1%(17/53)] in the frailty group was significantly higher than that in the non-frailty group [65.8%(50/76), 1.3%(1/76), 17.1%(13/76); t=5.001, χ 2=5.879, 24.606, 3.921; all P<0.05]. Compared with non-frailty group, turbulence onset (TO) [-0.05(-0.92, 0.82)% vs. -0.74(-1.58, 0)%; Z=2.616, P=0.009] was significantly higher in frailty group, while turbulence slope (TS) [2.34(1.30, 5.00)ms/RR vs. 4.34(2.66, 6.39)ms/RR; Z=-3.048, P=0.002] was significantly lower. The rate of TO abnormality [49.1% (26/53) vs. 26.3%(20/76), χ 2=7.038, P=0.008] and TS abnormality [34.7%(29/53) vs. 21.0%(16/76); χ 2=15.579, P<0.001] in the frailty group was significantly higher than that in the non-frailty group. Multivariate logistic regression analysis showed that TO abnormality( OR=2.970, P=0.010, 95 %CI:1.300-6.785) and TS abnormality( OR=3.618, P=0.003, 95 %CI:1.565-8.364) were correlated with frailty. Conclusion:Cardiac autonomic nerve function may be impaired in elderly frail patients, and decreased vagal nerve tension may be presented.

Objective To investigate the clinical characteristics of gastrointestinal involvement in polyarteritis nodosa (PAN),and to improve the understanding of the disease.Methods PAN patients hospitalized in Peking Union Medical College Hospital from March 2002 to September 2016 were enrolled in this study,and were divided into gastrointestinal involvement group and non-gastrointestinal involvement group according to clinical manifestations and imaging findings.Data on clinical features,treatments and outcome were recorded.t test,chi-square test were used for statistical analysis.Results A total of 117 patients with PAN were hospitalized in the past 14 years.The prevalence of gastrointestinal involvement was 38％(44 cases).There was no significant difference in age and sex between the two groups (P＞0.05).Abdominal pain (29 cases,66％) was the most frequent manifestation,then gastrointestinal bleeding (10 cases,23％),splenic infarction (3 cases,7％),gastrointestinal ulcers (2 cases,5％),intestinal obstruction or diarrhea (each 2 cases,5％),and vomiting (1 case,2％).Patients with gastrointestinal involvement had more frequent fatigue (27％ vs 11％;x2=5.156,P=0.023),increased diastolic pressure (55％ vs 34％;x2=4.647,P=0.031),renal (34％ vs 18％;x2=3.998,P=0.046) and cardiac (25％ vs 8％;x2=6.225,P=0.013) involvements.ESR in the gastrointestinal involvement group was significantly higher (75％ vs 56％;x2=4.190,P=0.041).The average follow-up time was 315.8 (20.3,441.3) days,the relapse rate was higher in the gastrointestinal involvement group (23％ vs 8％;x2=4.895,P=0.027).The incidence of death or the irreversible organ injury was higher in the gastrointestinal involvement group (27％ vs 11％,x2=5.156,P=0.023).Conclusion Gastrointestinal invol-vement in poly-arteritis nodosa is common and its condition is severe.The incidence of relapse and death or irreversible organ injury is high.
