Patients with Takayasu arteritis combined with aortic valve disease often have a poor prognosis following surgical valve replacement, frequently encountering complications such as perivalvular leakage, valve detachment, and anastomotic aneurysm. This article presents a high-risk case wherein severe aortic valve insufficiency associated with Takayasu arteritis was successfully managed through transcatheter aortic valve implantation via the transapical approach. The patient had satisfactory valve function with no complications observed during the six-month postoperative follow-up. This case provides a minimally invasive and feasible alternative for the clinical management of such high-risk patients.

Objective To explore the clinical value of three-dimensional(3D)fracture mapping in improving the consistency of Arbeitsgemeinschaft für Osteosynthesefragen(AO)/the Orthopaedic Trauma Association(OTA)classification and optimizing preoperative surgical planning for Pilon fractures.Methods This single-center retrospective cohort study included 60 Pilon fracture patients admitted to the Trauma Emergency Center of the Third Hospital of Hebei Medical University between January 2022 and December 2024.All patients underwent preoperative computed tomography(CT)scans.Image standardization and expert manual segmentation/annotation of fracture lines and fragments were performed with 3D Slicer software.3D fracture lines extracted from gold-standard models were registered to a unified standard tibial model.A 3D probability heatmap was constructed by counting spatial fracture frequency,with high-incidence zones analyzed via spatial clustering algorithms.Three orthopedic surgeons independently completed AO/OTA classification and preoperative planning with the assistance of conventional CT only and CT with 3D fracture mapping.Accuracy,time consumption,inter-observer consistency(Cohen's κ),planning time,plan modification frequency,and subjective scores were evaluated.Results The 3D fracture heatmap revealed that fracture lines predominantly concentrated in the anterolateral and posteromedial regions of the distal tibia,with an average of(4.2±1.1)hotspots,a coverage rate of(78.3±5.6)%,and(3.5±1.0)clustering areas.With 3D fracture mapping assistance,classification accuracy was improved to(88.0±5.0)%compared to(75.0±8.0)%with conventional CT(P=0.001);classification time reduced to(10.4±2.5)min from(15.2±3.1)min(P<0.001);and Cohen's κ increased from 0.68±0.05 to 0.82±0.03(P=0.002).For preoperative planning,the average planning time was(15.8±3.2)min in the 3D mapping-assisted group,which was significantly shorter than that of conventional CT group(22.5±4.3)min(P<0.001);the number of plan modifications was(1.5±0.7)times,lower than that of conventional CT group(3.2±1.1)times(P<0.001),and the subjective score was 8.9±0.9,higher than that of conventional CT group(6.8±1.2)(P<0.001).Conclusion The 3D fracture mapping accurately characterizes spatial distribution patterns of Pilon fractures,significantly improves classification accuracy,inter-observer consistency,and preoperative planning efficiency,and thus holds substantial clinical value.

Objective To investigate the diagnostic value of plasma heparin-binding protein(HBP)in the bloodstream infection of tumor patients.Methods The tumor patients treated at Ruijin Hospital,Shanghai Jiao Tong University School of Medicine from Janu-ary 2023 to December 2023 were selected and further divided into the following three groups:124 patients with positive blood cultures(bloodstream infection group),95 with negative blood cultures but positive cultures from other body fluids(culture-positive group),and 100 with negative bacterial cultures(culture-negative group).The levels of HBP,procalcitonin(PCT),C-reactive protein(CRP),interleukin 6(IL-6),white blood cell(WBC),and neutrophil(NE)in the three groups were detected.The level differences of each indicator among three groups were compared.The differences in the expression levels of HBP in the bloodstream infection group with different pathogens such as Gram-negative bacteria,Gram-positive bacteria,and fungi were also compared.The Logistic regression analysis was used to evaluate the predictive efficacy of each indicator for the risk of bloodstream infection.The receiver operating char-acteristics(ROC)curve was used to assess the diagnostic value of each indicator alone and in combination for the bloodstream infection of tumor patients.Results The expression level of HBP in the bloodstream infection group(32.14[14.01,110.40]ng/mL)was sig-nificantly higher than that in the culture-positive group(23.00[5.90,54.87]ng/mL,t=5.39,P＜0.05),and both of them were sig-nificantly higher than that in the culture-negative group(6.80[5.90,16.05]ng/mL,Z=47.248,P＜0.05).HBP had a certain clini-cal predictive value for the occurrence of bloodstream infection in tumor patients(OR=1.017,95％CI:1.008～1.027,P＜0.001).In addition,the levels of HBP in the Gram-negative bacterial infection group(78.04[21.60,157.20]ng/mL)were significantly higher than that in the Gram-positive bacterial infection group(51.00[18.45,106.50]ng/mL,t=2.01,P＜0.05),and both of them were significantly higher than that in the fungal infection group(5.90[5.90,14.17]ng/mL,Z=3.40,P＜0.05).The area under the ROC curve(AUCROC),sensitivity,and specificity of HBP for the diagnosis of bloodstream infection in tumor patients were 0.717,67.37％,and 67.26％,respectively,which were superior to those of PCT(0.700,77.17％,and 52.14％),CRP(0.667,63.16％,and 62.39％),and IL-6(0.629,60.47％,and 60.47％).The AUCROC,sensitivity,and specificity of the combination of HBP,CRP,PCT,and IL-6 were 0.739,70.24％,and 68.42％,respectively,which were better than those of each indicator alone.Conclusion The detection of HBP has high clinical application value in the diagnosis of bloodstream infections of tumor patients and may serve as a potential biomarker for the bloodstream infection of tumor patients.

Objective:The current situation of economic talents in public Traditional Chinese Medicine(TCM)hospitals provides a basis for strengthening the construction of economic talents in TCM hospitals and improving the economic management level of public TCM hospitals.Methods:According to the relevant data of chief accountants and accountants of public TCM hospitals in the annual health financial report from 2016 to 2022,the number of other economic management personnel is estimated.Based on descriptive vertical statistic comparison,the changes of economic management personnel in various types of public TCM in China from 2016 to 2022 were compared horizontally,and the differences in the allocation of economic management personnel in various types of public TCM hospitals among different regional levels were compared.Results:From 2016 to 2022,the proportion of chief accountants in public TCM hospitals in China increased from 10.1%to 22.8%.Public TCM hospitals increased the most accountants in public TCM hospitals are mainly charging personnel.Most accountants are undergraduate students in the east and junior colleges in the middle and west,and the proportion of those without accounting titles.By 2022,the total number of economic management personnel in public TCM hospitals was be 54 000,accounting for 4.6%of the on-the-job employees,but the total number increased but the proportion decreased.Conclusion:Although the allocation of chief accountant in public TCM hospitals has been improved,the chief accountant system still needs to be further implemented;regional differences of accountants are large and high-quality talents are lacking;the shortage of economic management personnel has not yet formed a characteristic team.It is suggested that public TCM hospitals need to promote the integration of business and finance,strengthen training,introduce talents,train high-end compound talents and improve the efficiency of economic management.

Schizophrenia (SZ) stands as a severe psychiatric disorder. This study applied diffusion tensor imaging (DTI) data in conjunction with graph neural networks to distinguish SZ patients from normal controls (NCs) and showcases the superior performance of a graph neural network integrating combined fractional anisotropy and fiber number brain network features, achieving an accuracy of 73.79% in distinguishing SZ patients from NCs. Beyond mere discrimination, our study delved deeper into the advantages of utilizing white matter brain network features for identifying SZ patients through interpretable model analysis and gene expression analysis. These analyses uncovered intricate interrelationships between brain imaging markers and genetic biomarkers, providing novel insights into the neuropathological basis of SZ. In summary, our findings underscore the potential of graph neural networks applied to multimodal DTI data for enhancing SZ detection through an integrated analysis of neuroimaging and genetic features.

This article provides a systematic review of the research progress in the mechanisms related to lung cancer and ferroptosis， ferroptosis-related lung cancer biomarkers and gene mutation targets， and ferroptosis-targeted regulation of Chinese medicine in treating lung cancer in the past five years， providing a feasible and effective basis for the prevention and treatment of lung cancer with Chinese medicine and the development of new drugs. According to the available studies， ferroptosis is widely suppressed in lung cancer， while the specific regulatory mechanisms have not been fully elucidated. The suppression is related to lipid metabolism， iron metabolism， cystine/glutamate antiporter system Xc^- （System Xc^-）/glutathione （GSH）/glutathione peroxidase 4 （GPX4）， ferroptosis suppressor protein 1 （FSP1）/coenzyme Q10 （CoQ10）/nicotinamide adenine dinucleotide phosphate ［NAD（P）H］， long non-coding RNA （lncRNA）， nuclear factor E₂-related factor 2 （Nrf2）， and p53. In modern times， traditional Chinese medicine is widely used in the comprehensive treatment of lung cancer， and it has gradually become a hot research topic due to its obvious advantages of anti-tumor activity， high efficacy， and low toxicity. Traditional Chinese medicine plays an important role in the treatment of lung cancer. Studies have shown that the active components， extracts， and prescriptions of Chinese medicine can induce ferroptosis in lung cancer cells through targeted regulation of iron metabolism， lipid metabolism， and p53， Nrf2， LncRNA， and GPX4 pathways to inhibit the growth and proliferation of lung cancer， thus exerting anti-tumor effects. Therefore， regulating ferroptosis is expected to become a new direction for preventing lung cancer. Basic research has shown that Chinese medicine can regulate ferroptosis via multiple targets and pathways in the treatment of lung cancer. At present， Chinese medicine demonstrates great research prospects in regulating ferroptosis to treat lung cancer， which， howeve， still faces challenges to achieve clinical transformation.

Objective: To investigate the association between habitual reading/writing postures and the co-occurrence of common health conditions (overweight/obesity, visual impairment, hypertension, and scoliosis) and comorbidities among children and adolescents, in order to provide data support for the joint prevention of common diseases and comorbidities among children and adolescents. Methods: From September 2021 to June 2022, a multi-stage cluster random sampling method was used to select a total of 4 577 children and adolescents from 16 primary and secondary schools in Ningxia: Jinfeng District of Yinchuan City, Shapotou District of Zhongwei City, Yanchi County of Wuzhong City, and Pingluo County of Shizuishan City. A weighted complex sampling design was used to investigate the association of habitual reading and writing postures with common comorbidities in children and adolescents. Results: The prevalence rates of common diseases among children and adolescents in Ningxia were as follows: overweight/obesity was 22.87%, visual impairment was 62.52%, scoliosis was 2.30%, and hypertension was 1.30%. The prevalence of multimorbidity (co-occurrence of ≥2 conditions) among Ningxia children and adolescents was 15.95%. Multivariate unconditional Logistic regression analysis showed that frequent/always collapsing waist and sitting forward with head lowered increased the risk of common comorbidities in children and adolescents ( OR =1.90, P <0.05). Compared with the corresponding reference group, male children and adolescents aged 9 to 12 years and boys had relatively lower risks of overweight/obesity ( OR =0.71, 0.70); the risk of poor vision among children and adolescents aged 9 to 12 years, male, and urban was relatively low ( OR =0.59, 0.60, 0.73)( P < 0.05 ). Children and adolescents who often/always sat leaning to the left or right were at higher risk of poor vision ( OR =1.78); urban children and adolescents had a higher risk of developing scoliosis ( OR =3.71); children and adolescents aged 9 to 12 had a relatively low risk of developing hypertension ( OR =0.09), and children and adolescents who often/always bent their backs and sat forward on their knees had a higher risk of hypertension ( OR =5.03)( P <0.05). Conclusions Ningxia has a high incidence of common diseases and multiple diseases among children and adolescents, frequent or always collapsing waist and sitting forward with head lowered is associated with common comorbidities in children and adolescents in Ningxia. Proper postural measures for reading and writing should be carried out as soon as possible to encourage children and adolescents to develop good reading and writing habits for effectively preventing and controlling the occurrence of common diseases.

Antibody-drug conjugates (ADCs) represent a promising class of targeted cancer therapeutics that combine the specificity of monoclonal antibodies with the potency of cytotoxic payloads. Despite their therapeutic potential, the use of ADCs faces significant challenges, including off/on-target toxicity and resistance development. This review examines the current landscape of ADC development, focusing on the critical aspects of target selection and antibody engineering. We discuss strategies to increase ADC efficacy and safety, including multitarget approaches, pH-dependent antibodies, and masked peptide technologies. The importance of comprehensive antigen expression profiling in both tumor and normal tissues is emphasized, highlighting the role of advanced technologies, such as single-cell sequencing and artificial intelligence, in optimizing target selection. Furthermore, we explore combination therapies and innovations in linker‒payload chemistry, which may provide approaches for expanding the therapeutic window of ADCs. These advances pave the way for the development of more precise and effective cancer treatments, potentially extending ADC applications beyond oncology.
