ObjectiveTo address the shortage of high-caliber multidisciplinary professionals in China's rehabilitation engineering field and the prominent issue of "separation between medicine and engineering" in existing curricula, this study introduces the World Health Organization rehabilitation competency framework (RCF) to construct a systematic curriculum system for rehabilitation engineering. MethodsGuided by the four core competency domains of RCF (practice, professionalism, learning and development, management and leadership) and their associated supporting knowledge, the rehabilitation engineering curriculum was restructured into a modular framework, piloted and validated within the Biomedical Engineering (Intelligent Robotics) program at University of Health and Rehabilitation Sciences. ResultsA four-tiered curriculum system comprising General Education-Disciplinary Platform-Professional Core-Diverse Electives with a total of 160 credits was established, achieving precise mapping between competency objectives and course content. The students in the pilot cohort demonstrated outstanding academic performance (50% ranked in the top ten of their major), they also gained a deeper understanding and mastery of interdisciplinary knowledge integrating medicine and engineering. ConclusionThe RCF-based curriculum system effectively promotes the organic integration of medical and engineering knowledge, providing an internationally aligned competency-oriented paradigm for rehabilitation engineering talent cultivation, which holds significant value for broader application.

ObjectiveTo investigate the potential targets and mechanisms of Draconis Sanguis (DS), a valuable traditional Chinese medicine derived from the resin of the palm tree Daemonorops draco Bl (D. Sanguis, Xue Jie), in the treatment of myocardial infarction (MI).MethodsWe explored the potential mechanisms of DS in the treatment of MI using network pharmacology, bioinformatic techniques, and transcriptomic analysis, followed by validation through in vivo and in vitro experiments.ResultsNetwork pharmacology and bioinformatic analyses identified five genes (Fpr1, Glul, Mme, Mmp9, and Pla2g7) as potential targets for MI treatment. Moreover, DS significantly ameliorated cardiac function, inflammatory responses, and MI-induced myocardial fibrosis in vivo. Transcriptomic and bioinformatic analyses identified Pla2g7 as the most critical target in the DS treatment of MI. Molecular docking revealed that the key active ingredient in DS has a strong affinity for this gene. Furthermore, DS reduced the expression of Pla2g7 (P = .0009), NLRP3 (P = .003), interleukin-18 (P .001), and interleukin-1β (P = .004) mRNAs in vivo.ConclusionsThe results indicate that DS can downregulate the expression of Pla2g7 and reduce the inflammatory response. This demonstrates the potential therapeutic target of DS and the mechanism underlying its cardioprotective effects.

Objectives:To explore the relationship between carboxymethyl lysine (CML) and type 2 diabetes (T2DM) with myopenia, so as to provide some clinical reference for clinical prevention and early intervention of myopenia.Methods:A case-control study was conducted, selecting 142 T2DM patients admitted to the Endocrinology Department of the Affiliated Hospital of North China University of Science and Technology from November 2022 to November 2023. According to the diagnostic criteria of the 2019 consensus of experts on the diagnosis and treatment of sarcopenia, the patients were divided into a case group (T2DM with sarcopenia, 58 cases) and a control group (T2DM without sarcopenia, 84 cases). Collect and compare general information, serological data, and body composition data of two groups of patients. Two independent sample t-test is used for inter group comparison of metric data that conforms to normal distribution; Non parametric tests are used for inter group comparisons of non normally distributed quantitative data; The comparison of count data between groups is conducted using χ2 test. Multivariate logistic regression analysis was used to analyze the relationship between carboxymethyl lysine and type 2 diabetes with myopenia. Draw receiver operating characteristic (ROC) curves and analyze the efficacy of carboxymethyllysine in diagnosing T2DM with muscle atrophy. Results:Univariate analysis showed the BMI ((21.59±3.04) kg/m 2), FINS (4.49 (1.85,9.03) U/L), and FCP ((1.45±0.96) mg/L) levels of the patients in the case group were lower than those in the control group(27.32±3.74) kg/m 2, 6.91 (3.74, 11.99) U/L, (2.64±1.23) mg/L), while age, ((64.67±6.75) years old) of disease duration(12.16±6.69) years, and CML (5.70±2.14 μg/L) were higher than those in the control group ((62.23±7.33) years old, (8.70±8.01) years, (2.38±0.73) μg/L), and the differences were statistically significant (Statistical values were t=9.66, Z=2.86, t=6.46, t=2.02, t=2.70, t=13.17; P values were <0.001, 0.004, <0.001, 0.046, 0.008, <0.001). Multifactorial binary logistic regression analysis showed that CML ( OR(95%CI):3.242 (1.933-5.437)) and BMI ( OR(95%CI):0.636 (0.505-0.801)) were associated with T2DM combined with sarcopenia (all P<0.001). The results of the ROC curve showed that the area under the curve (AUC) of CML was 0.934, and the corresponding optimal cut-off value was 3.038 μg/L. The diagnostic efficacy of CML for the diagnosis of T2DM combined with myasthenia gravis was high, and the diagnostic results were in good agreement with the actual results. Conclusions:Carboxymethyl lysine is associated with T2DM combined with muscle atrophy. CML has a high diagnostic efficacy in diagnosing T2DM combined with muscle atrophy, and it has certain practical value in diagnosing T2DM combined with muscle atrophy.

Objective:To investigate the clinicopathological characteristics of lung transplantation and post-transplantation changes in patients with pneumoconiosis.Methods:A retrospective study was conducted to analyze the clinical and pathological data of 28 patients with pulmonary silicosis who underwent lung transplantation and were managed at the Department of Internal Medicine, Henan Provincial People′s Hospital, Zhengzhou, China from January 2015 to December 2024. Among them, 8 patients underwent lung biopsy 6-20 months after transplantation to evaluate the histopathological changes of the recipient and the donor lungs post-transplantation. The expression of relevant indicators was examined using immunohistochemical EnVision staining, while presence of microorganisms was assessed using histochemical special staining. The patients were all followed up.Results:Among the 28 patients with pneumoconiosis who underwent lung transplantation, 26 were male and 2 were female, with a male-to-female ratio of 13∶1. Their ages ranged from 23 to 68 years, median 50.0 (46.0, 53.5) years. They were diagnosed with pneumoconiosis at local occupational disease prevention and control centers for 3 to 15 years (mean, 9.65 years), including 13 left single lung transplants and 15 right single lung transplants. Gross examination showed fleshy nodules with irregular cystic cavities at the periphery. The cut surfaces exhibited gray-brown color and firm texture. Microscopically, most alveolar structures of the lung were obliterated, with nodular or diffuse proliferation of collagen fibers accompanied by hyaline degeneration. Focal massive carbon dust deposition and massive silicotic fibrosis were observed, surrounded by lung parenchyma with emphysematous changes and localized bullae formation. Seven patients underwent re-biopsy after transplantation that showed extensive infiltration of inflammatory cells. In 4 cases, microscopy revealed complete coagulative necrosis, with negative acid-fast staining and TB-DNA results. Of the 4 cases, 3 cases exhibited Aspergillus infection confirmed by Grocott′s methenamine silver and PAS stains, while 2 cases showed chronic bronchitis with squamous metaplasia. Follow-up revealed that 8 patients died of acute respiratory failure due to severe infection, while the remaining 20 demonstrated significant postoperative improvement in lung function.Conclusions:For patients with advanced pulmonary dust deposition disease who undergo lung transplantation, it is necessary to conduct standardized sampling and pathological assessment of the recipient lungs. In the early post-transplant period, the complications of re-biopsy tissues are mainly fungal infections. The combination of morphological manifestations and immunohistochemical detection is helpful to distinguish infection from rejection reactions. At the same time, it is essential to integrate clinical information and laboratory results to provide post-transplantation pathological assessment for individualized treatment.

The present study examines combs the connotation and development of the HIV/AIDS care cascade, exploring application throughout the entire process and at each linkage. It analyzes extension value in key populations and HIV co-infected other infectious diseases, identifies obstacles in practice, and proposes strategies to help optimize, innovate, and precisely target HIV/AIDS prevention and control in China.

Objective:To evaluate the relationship between the neutrophil-to-lymphocyte ratio (NLR) during the perioperative period and early postoperative recurrence in patients with advanced gastric cancer.Methods:In this prospective study, 188 American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ patients, aged 18-75 yr, with a body mass index of 20-30 kg/m 2, with radiological staging of T 2-4N xM 0, underwent elective gastric cancer radical surgery under general anesthesia at the Fourth Hospital of Hebei Medical University from January 2018 to April 2022, were selected. The NLR was measured at 1 day before operation and postoperative days 1, 3 and 5. The difference between postoperative and preoperative NLR (ΔNLR) was calculated. Based on the presence or absence of tumor recurrence and/or metastasis within 2 yr after surgery, the patients were divided into recurrence group and non-recurrence group. The Cox proportional hazards regression model was employed to evaluate the early postoperative recurrence and perioperative NLR in patients with advanced gastric cancer. Results:A total of 171 patients ultimately completed the follow-up. There were 77 cases in recurrence group and 94 in non-recurrence group. Compared to non-recurrence group, NLR and ΔNLR were significantly increased on the 5th day after operation in recurrence group ( P<0.05). The elevated NLR and ΔNLR at postoperative day 5 were independent risk factors for recurrence within 2 yr in patients with advanced gastric cancer ( HR=1.026, P<0.05). Conclusions:NLR may not be associated with the risk of early postoperative recurrence in the patients with advanced gastric cancer, and further evaluation with large-scale studies is needed.

Objective To explore the effectiveness of a hospital-to-home transitional health management program for caregivers of children with severe encephalitis,aiming to provide a reference for optimizing transitional care models for these patients.Methods A convenience sampling method was used to select 84 children with severe encephalitis and their caregivers admitted to the neurology department of a tertiary hospital in Zhengzhou between March 2023 and June 2024.According to the admission time,they were divided into an experimental group and a control group,with 42 cases in each group.The experimental group received a hospital-to-home transitional health management program in addition to routine care,while the control group received standard care and discharge instructions.Differences in caregivers' perceived benefits,caregiver burden,disease management ability,and post-intervention outcomes of the children were compared between the 2 groups before and after the intervention.Results All 42 participants in both groups completed the study.After the intervention,the experimental group reported higher perceived benefits of(91.29±9.76)compared to(84.81±12.86)in the control group,lower caregiver burden of(48.55±7.15)compared to(54.71±11.23)in the control group,greater disease management ability of(41.83±4.97)than(37.79±5.23)in the control group,and lower difficulty in disease management of(31.52±7.82)compared to(34.55±3.96)in the control group,with all differences being statistically significant(P＜0.05).No statistically significant difference was found in the prognosis of the children between the 2 groups(P=0.500).Conclusion The hospital-to-home transitional health management program can effectively enhance caregivers'perceived benefits and disease management capabilities,reduce their caregiving burden,and provide scientific evidence for optimizing transitional care for children with severe encephalitis.

Objective:To investigate the clinical value of anorectal ultrasound in diagnosing the internal opening of anal fistulas.Methods:A total of 1 353 patients with anal fistulas who were admitted to the Department of Anorectal Surgery at Ningbo No.2 Hospital and underwent anorectal ultrasound examinationResults:The accuracy of anorectal ultrasound in diagnosing the internal opening of anal fistulas was 89.32%. The accuracy for simple anal fistulas was 95.96% compared to 77.86% for complex anal fistulas，with a statistically significant difference（ χ2=178.328， P<0.001）. Further analysis revealed significantly higher rates of misdiagnosis and missed diagnosis in complex anal fistulas（ R=3.776，9.009），with statistically significant differences（| R|>1.960）. Conclusions:Anorectal ultrasound demonstrates high accuracy in diagnosing the internal opening of anal fistula，providing valuable guidance for clinical treatment decisions.

Purpose To explore the diagnostic value of two-dimensional speckle tracking echocardiography(2D-STE)in differentiating left ventricular hypertrophy(LVH)caused by Fabry disease from other etiologies.Materials and Methods A total of 23 patients clinically confirmed Fabry disease with LVH(Fabry disease group)in Peking University First Hospital from August 2014 to February 2023,retrospectively.23 patients with hypertensive LVH(hypertensive LVH group)and 23 with hypertrophic cardiomyopathy(HCM)(HCM group)were also included.Conventional echocardiographic parameters and 2D-STE-derived left atrial strain and left ventricular longitudinal strain were analyzed and compared among the three groups.LASSO regression was used to select variables and construct a diagnostic model to differentiate hypertensive LVH,HCM and Fabry disease group.Results The Fabry disease group showed significantly reduced left ventricular global longitudinal strain and segmental left ventricular longitudinal strain in the basal anterior wall,basal anterolateral wall and mid inferior wall compared to the hypertensive LVH group(P<0.05).There were no significant differences in left atrial strain,left ventricular global longitudinal strain and segmental left ventricular longitudinal strain between the Fabry disease and HCM groups(P>0.05).Compared to the conventional echocardiography-based model,the combined model did not significantly improve diagnostic accuracy for differentiating the three etiologies(Z=-1.314--0.594,all P>0.05).Conclusion Compared to patients with hypertensive LVH,HCM and Fabry disease group exhibit varying degrees of decrease in global and segmental longitudinal strain of the left atrium and left ventricle.Additional measurements of left ventricular longitudinal strain and left atrial strain do not provide significant incremental diagnostic value over conventional echocardiography in distinguishing among Fabry disease,hypertensive LVH and HCM.
