ObjectiveTo delineate imaging findings using an imaging platform and investigate the correlation between MRI characteristics of spinal cord atrophy and clinical diagnosis in children with spinal cord injury (SCI). MethodsImaging data of 150 children with SCI admitted to Beijing Bo'ai Hospital, China Rehabilitation Research Center, from January, 2002 to March, 2024 were collected and imported into the imaging platform. The anteroposterior and transverse diameters of the middle part of the spinal cord at the cross-section with the most severe atrophy were measured, and the relevant indicators of the previous normal spinal cord segment were measured as controls; the radiomic features were extracted. Clinical data of the children including gender, age, cause of injury, sensory level, motor level, spinal cord injury level, injury severity and disease course were collected. ResultsSpinal cord atrophy was identified in 81 cases (54%), among which 78 cases (96%) were American Spinal Injury Association Impairment Scale (AIS) grade A and 3 cases (4%) were AIS grade C. The upper boundary of the spinal cord atrophy site strongly correlated with the injury level, motor level and sensory level (r > 0.8, P < 0.001). ConclusionMore than half of children with SCI may develop secondary spinal cord atrophy, the vast majority of whom suffer from complete spinal cord injury; the upper boundary of spinal cord atrophy is correlated with the injury level.

ObjectiveTo construct an actor-network for integrating physical activity into rehabilitation services based on the World Health Organization Rehabilitation in Health Service System framework and actor-network theory (ANT). MethodsContent analysis was employed using the six building blocks of health service systems as the theoretical framework. Actors related to rehabilitation services were extracted and categorized into a rehabilitation actor pool, while a physical activity actor pool was formed based on four major physical activity scenarios. Actors from both pools were integrated, deduplicated and classified to form a final list of integrated actors. Using ANT, the construction process of the actor network integrating physical activity into rehabilitation was analyzed through the four stages of translation: problematization, interessment, enrollment and mobilization. ResultsA dynamic integration network was constructed, comprising human actors (patients, rehabilitation professionals, researchers, sports coaches, government departments, medical institutions, community organizations and industry media, etc.) and non-human actors (assistive devices, sports infrastructure, smart equipment, information systems, online exercise guidance systems, laws and regulations, strategic documents, and exercise prescriptions, etc.). The study identified maximizing rehabilitation outcomes as the mandatory passage point and elaborated on the critical role of government departments as focal actors in coordinating various stakeholders. ConclusionThe integration of physical activity into rehabilitation services is a dynamic network constructed by diverse actors through a process of translation. ANT provides an operational theoretical framework for cross-departmental governance of rehabilitation policies in China, promotes the spatial expansion of the rehabilitation field, and drives its transformation toward a networked and ecological system. The government needs to play a leading role in facilitating role reconstruction and synergy among heterogeneous actors in both the sports and rehabilitation sectors through mechanism design, to create a bidirectional empowerment mechanism that fosters mutual progress and ensures the sustainable development of integrated services.

BACKGROUND:The traditional surgical treatment for stromal corneal dystrophy is penetrating keratoplasty.In recent years,more and more doctors are considering using deep lamellar keratoplasty to treat stromal corneal dystrophy.Few studies comparing penetrating keratoplasty and deep lamellar keratoplasty for stromal corneal dystrophy have been reported in China. OBJECTIVE:To compare the clinical efficacy of deep lamellar keratoplasty and penetrating keratoplasty in the treatment of stromal corneal dystrophy. METHODS:Fifty-seven patients(57 eyes)diagnosed with stromal corneal dystrophy and admitted at the General Hospital of Northern Theater Command from January 2000 to January 2018 were selected,including 18 males and 39 females,aged(52.9±20.0)years.They were divided into two groups based on the surgical procedure:21 cases(21 eyes)in the deep lamellar keratoplasty group and 36 cases(36 eyes)in the penetrating keratoplasty group.A 12-month follow-up was conducted to observe the best-corrected visual acuity,corneal endothelial cell density,corneal grafttransparency,intraoperative and postoperative complications,and recurrence of the original disease. RESULTS AND CONCLUSION:Visual acuity at 1,3,6,and 12 months postoperatively was higher than preoperatively in both groups(P<0.05).The postoperative best-corrected visual acuity between the two groups showed no significant difference(P>0.05).With the prolongation of postoperative time,the corneal endothelial cell density gradually decreased in the two groups,and the annual loss rate of corneal endothelial cell density in the penetrating keratoplasty group was higher than that of the deep lamellar keratoplasty group at 6 and 12 months postoperatively(P<0.05),while there was no significant difference in corneal grafttransparency between the two groups at 12 months postoperatively(P>0.05).There were six cases of complications in the deep lamellar keratoplasty group and 14 cases of complications in the penetrating keratoplasty group.There was no recurrence in 57 cases within 12 months after surgery,and the difference in recurrence rates between the two groups at 5 years after surgery was not significant(P>0.05).The graftsurvival rates at 5 years after surgery in the penetrating keratoplasty group and the deep lamellar keratoplasty group were 83%and 86%,respectively,and there was no significant difference between the two groups(P>0.05).To conclude,deep lamellar keratoplasty could be considered as an alternative to penetrating keratoplasty in the treatment of stromal corneal dystrophy.

Objective:To investigate the value of a computed tomography(CT)radiomics-based model for predicting the efficacy of neoad-juvant immunotherapy combined with chemotherapy for locally advanced gastric cancer(LAGC).Methods:Data on 114 patients with LAGC who underwent radical surgery after neoadjuvant immunotherapy combined with chemotherapy at The Second Affiliated Hospital of Xingtai Medical College between June 2019 and June 2021 were retrospectively collected.These patients'data were divided into a training set(n=67)and a validation set(n=47)based on the time of admission.High-throughput features were extracted from baseline portal phase CT images of all patients,and the selected features were used to construct the radiomics prediction model.The predictive performance of the model was evaluated using receiver operating characteristic(ROC)and calibration curves.The prognostic ability of the model was assessed using Kaplan-Meier curves.Results:Based on the maximum relevancy min-redundancy(mRMR)algorithm and least absolute shrinkage and selection operator(LASSO)regression model,5 out of 584 assessed features were incorporated into the radiomics(Rad)score.The respect-ive areas under the curve for predicting pathological complete response(pCR)in the training and validation sets were 0.865 and 0.830,re-spectively,and good fits were obtained(Hosmer-Lemeshow test:P>0.05).The optimal cut-off value for the Rad score was determined based on the Youden index.Patients with high Rad scores had significantly higher 3-year recurrence-free survival rates(82.7%vs.60.4%in the training set and 78.9%vs.53.8%in the validation set)and 3-year overall survival rates(78.9%vs.60.2%in the training set and 79.3%vs.50.0%in the validation set)than those with low Rad scores(P<0.05).Conclusions:The CT radiomics prediction model effectively predicted the pathological response and prognosis of patients with LAGC after neoadjuvant immunotherapy combined with chemotherapy and is ex-pected to serve as a practical clinical tool.

BACKGROUND:If not detected and treated in a timely manner,immune-associated peripheral ulcerative keratitis can lead to corneal thinning,ulcers and even perforation,thereby causing visual loss and affecting the patient's quality of life.OBJECTIVE:To discuss the pathogenesis of immune-associated peripheral ulcerative keratitis and summarize the diagnosis and treatment ideas and the latest treatment methods for this disease.METHODS:Search terms were"peripheral ulcerative keratitis,immunity,immune system disease,pathogenesis,immunomodulatory therapy,surgical treatment,keratoplasty"in English and Chinese.Relevant literature on peripheral ulcerative keratitis published from database inception to October 2024 was searched by computer in CNKI,WanFang,PubMed,and El databases.A total of 68 papers were ultimately selected to comprehensively describe the new research progress in the research on immune-associated peripheral ulcerative keratitis.RESULTS AND CONCLUSION:Immune-associated peripheral ulcerative keratitis includes Mooren's ulcer,blepharokeratoconjunctivitis,superior limbic keratoconjunctivitis,and autoimmune related peripheral ulcerative keratitis.Due to the physiology of the corneal limbus,peripheral ulcerative keratitis is usually associated with an immune response,and the pathophysiologic mechanism is usually related to the deposition of immune complexes in the blood vessels at the limbus and the production of microangiitis.Systemic immunomodulatory therapy should be used whether or not an autoimmune disease is diagnosed prior to the onset of immune-associated peripheral ulcerative keratitis,which can help to reduce ocular complications associated with systemic inflammation.Nonsurgical treatment,such as immunomodulatory therapy,is beneficial for relieving ocular symptoms,but when nonsurgical treatment is ineffective or the lesion infiltrates the Descemet membrane,it can cause corneal perforation.Combined surgical treatment can help maintain the structural integrity of the eyeball.However,there is no clear evidence for the combination of immunomodulatory therapy and surgical treatment in the development of immune-associated Peripheral ulcerative keratitis.This article reviews the literature on the diagnosis and treatment of immune-associated peripheral ulcerative keratitiss.

Objective:To evaluate the long-term clinical efficacy and the influence on anal function of surgery combined with ustekinumab (UST) in active Crohn's disease (CD) patients with perianal fistula.Methods:A retrospective cohort study was conducted. Clinical data of active CD patients with perianal fistula undergoing surgery combined with UST at Longhua Hospital of Shanghai University of Traditional Chinese Medicine from August 2020 to December 2022 were collected. The primary endpoints were clinical healing rate, Wexner score, and anorectal manometry values at week 52 of treatment. Secondary endpoints included the Crohn's disease activity index (CDAI), perianal Crohn's disease activity index (PDAI), laboratory indicators [C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), fecal calprotectin (FC) ], endoscopic remission rate, Van Assche score, and radiographic healing rate at week 52 of treatment.Results:A total of 28 patients were included, with 22 males (78.6%) and 6 females (21.4%) ; age (25.2 ± 7.7) (16.0-52.0) years. There was 1 patient (3.6%) of simple anal fistula. There were 27 patients (96.4%) of complex anal fistulas, including 12 of high intersphincteric type, 15 of high transsphincteric type, in which 15 with branched tracts (or ≥2 fistula tracts). The pre-treatment CDAI was 187.0 (156.0, 245.0), and the PDAI was 10.0 (9.0, 12.0). Among the 28 patients, 23 (82.1%) underwent fistulotomy, 1 (3.6%) underwent transanal opening of intersphincteric space (TROPIS), and 4 (14.3%) underwent video-assisted anal fistula treatment (VAAFT) combined with fistula-tract laser closure (FiLaC). All the patients received UST treatment postoperatively, without concurrent use of immunosuppressants or corticosteroid therapy. At week 52 of treatment, 28 (100%) patients achieved clinical healing. Compared to pre-treatment, Wexner score of patients at week 52 of treatment was significantly lower [0 (0, 0) vs. 1.0 (0, 3.0), P < 0.001], maximum anal sphincter pressure increased [ (137.6±40.9) mmHg vs. (105.1±29.2) mmHg, P < 0.001], maximum anal sphincter contraction time extended [9.0 (5.0, 15.0) s vs. 4.0 (2.0, 6.0) s, P < 0.001], and there was no significant decrease in anal resting pressure ( P > 0.05). Compared to pre-treatment, CDAI, PDAI, Van Assche scores, and simple endoscopic score for Crohn's disease (SES-CD) of patients at week 52 of treatment all significantly decreased (all P < 0.001), and CRP, ESR, and FC all decreased (all P < 0.05), with statistically significant differences. The radiographic healing rate at week 52 of treatment was 75.0% (21/28), and the radiographic remission rate was 92.9% (26/28). The endoscopic remission rate was 57.1% (16/28), and the endoscopic response rate was 82.1% (23/28) . Conclusion:The long-term clinical healing rate of active CD patients with perianal fistula receiving surgery combined with UST is high, and the anal function can be improved significantly.

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.
