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.

Intestinal tuberculosis (ITB) is a specific infection caused by Mycobacterium tuberculosis invading the intestinal wall, encompassing two types: primary and secondary. In clinical practice, it is more commonly secondary to extrapulmonary tuberculosis, such as cavitary pulmonary tuberculosis. In recent years, the incidence of ITB has shown an increasing trend. Due to its insidious onset and the lack of obvious or specific early symptoms, early diagnosis is challenging, often leading to a prolonged disease course. Therefore, accurate early diagnosis is of great significance for the control and prevention of ITB. Currently, the primary diagnostic methods for tuberculosis include etiological examination, histopathological evaluation, molecular biological diagnosis, and imaging studies. This article summarizes recent advances in the application of these diagnostic techniques for ITB, aiming to provide valuable insights for healthcare professionals.

The expert consensus on the clinical treatment of herpes zoster with fire needling was developed, and the commonly used fire needling treatment scheme verified by clinical research was selected to form a standardized diagnosis and treatment scheme for acute herpes zoster and postherpetic neuralgia (PHN), so as to answer the core problems in clinical application. The consensus focuses on patients with herpes zoster, and forms recommendations for 9 key clinical issues, covering simple fire needling and TCM comprehensive therapy based on fire needling, including fire needling combined with cupping, fire needling combined with Chinese herb, fire needling combined with cupping and Chinese herb, fire needling combined with filiform needling, fire needling combined with moxibustion, and provides specific recommendations and operational guidelines for various therapies.

Purpose To investigate the clinicopathological characteristics of the gastric oxyntic gland adenoma(GOGA).Methods We collected 18 samples of GOGA,histopathological features and immunohistochemical staining were assessed.Main features of pathological diagnosis,treatment methods and follow-up were retrospectively analyzed.Results There were 18 patients,including 9 females and 9 males,aged from 36 to 86 years old.The endoscopic im-age showed a flat lesion with whitish in color or a polypoid protrusions.The size ranged from 0.3 cm to 0.8 cm.Hema-toxylin and eosin staining showed irregular glandular structures in the mucosal lamina propria,with branched and anas-tomosed patterns.The tumour demonstrating composed of chief cells hyperplasia with mild nuclear atypia.All lesions were confined to the mucous lamina propria.There was no atrophic within the peripheral gastic mucosa.Immunohisto-chemical examination showed positive for Pepsinogen-Ⅰ and MUC6.Gene mutation were analyzed in 2 cases using next generation sequence technology,and no KRAS and GNAS mutation had been detected.Endoscopic surgical treatment was performed in 11 cases,and biopsy forceps removal was carried out in 7 cases.No recurrence or metastasis was ob-served during the follow-up period of 1 to 58 months.Conclusion GOGA is a rare lesion,and appears to behave bio-logically benign.A full understanding of its histological morphology and biological behavior can improve the diagnostic ability of clinincans,and facilitate further research in the future.

Objective:To analyze the morphologic changes and the extent of severity in end-stage heart disease; and to explore the correlation with their clinical features.Methods:Twelve cases of recipients who underwent pediatric cardiac allograft transplantation were collected from May 2022 to November 2023 at the Seventh Medical Center of People′s Liberation Army of China General Hospital. Gross pathologic examinations were performed and morphological changes were observed under a light microscope after HE, Masson′s trichrome, and reticulin staining. Semi-quantitative analysis of morphologic changes was performed. One case received DMD genetic testing, one received mtDNA variation testing for mitochondriopathy, and 1 received metagenomics next-generation sequencing. Clinical data and related literature were reviewed for comprehensive analysis.Results:There were 12 recipient hearts including 11 dilated cardiomyopathy (DCM) and 1 fulminant myocarditis (FM). The median age of DCM was 12 years (range, 3 to 15 years). DCM showed cardiomyocyte hypertrophy, cardiomyocyte disarray, nuclear morphological changes, interstitial fibrosis and fatty infiltration. One DCM was confirmed as Becker muscular dystrophy by DMD genetic testing. No pathogenic mutations were found in 1 patient that received mtDNA variation testing. H. influenzae was detected in the case of FM. FM showed diffuse and full-thickness inflammatory cell infiltration by large numbers of lymphocytes and plasma cells, scattered eosinophils, and few neutrophils.Conclusions:Cardiac transplantation is an excellent treatment for end-stage heart disease. The morphological features of DCM include cardiomyocyte hypertrophy, nuclear morphological changes, interstitial fibrosis and fatty infiltration. The severity of the lesion is influenced by multiple factors. FM predominantly presents diffuse infiltration of lymphocytes and plasma cells.

Objective:To assess the professional knowledge proficiency of mainstream large language models (LLMs) in medical laboratory education and to explore their potential as educational aids for medical laboratory technology students.Methods:A comprehensive evaluation was conducted using 400 authentic questions from the 2023 Chinese National Clinical Medical Laboratory Technician Qualification Examination. Five LLMs (Copilot, Grok, Yuanbao, Doubao, and Kimi) were tested through two-round interactions using zero-shot prompting and interaction-optimized prompting strategies. The accuracy of answers and the quality of generated content were evaluated. Performance disparities were analyzed using Cochran's Q test. Content quality was scored through the CLEAR framework (completeness, lack of false information, evidence-based reasoning, appropriateness, relevance).Results:In the first-round test, Doubao achieved the highest overall accuracy rate (375/400). The overall accuracy rates of Doubao and Yuanbao significantly outperformed Copilot and Kimi ( P<0.001). After the second-round interactive optimization, the accuracy rate of Kimi significantly improved ( P<0.05), whereas other LLMs showed slight improvements ( P>0.05). Doubao still had the highest overall accuracy rate (380/400). The overall accuracy rates of Doubao and Yuanbao significantly outperformed Copilot ( P<0.005). Evaluation based on the CLEAR framework revealed that Yuanbao, Doubao, and Kimi significantly outperformed foreign models in the dimensions of evidence-based reasoning ( P<0.003) and completeness ( P<0.05), demonstrating standardized citation of authoritative evidence and superior content quality. Conclusions:The tested LLMs possess extensive medical laboratory knowledge. The accuracy of their answers and the quality of the generated content can be improved through single-question input, specifying evidence requirements, and enabling advanced reasoning functions. Domestic LLMs are comparable to foreign LLMs in terms of accuracy, and have significant advantages in the dimensions of evidence-based reasoning and completeness. LLMs can serve as auxiliary tools for learning professional knowledge in medical laboratory technology.
