Objective:To investigate the risk factors for patients with hypertriglyceridemia-related acute pancreatitis (HTG-AP) developing into severe acute pancreatitis or experiencing organ failure.Methods:This retrospective cohort study collected clinical data from 2 429 patients diagnosed with acute pancreatitis from five hospitals in China between January 2019 and December 2023 using a pre-designed data collection form. The cohort included 1 516 males and 913 females,with an age of (50.2±16.5)years(range: 11 to 99 years). Among them,353 patients (16.1%) had HTG-AP,while 1 846 (83.9%) had non-HTG-AP. HTG-AP was defined as serum triglyceride levels>500 mg/dl with other etiologies excluded. Intergroup comparisons were performed using t-tests,Mann-Whitney U test or χ2 tests,respectively. Univariate and multivariate logistic regression analyses were conducted to assess risk factors for severe acute pancreatitis after adjusting for potential confounders,and a predictive model was developed and validated. Results:Compared with other etiologies,HTG-AP patients had a higher risk of progressing to SAP ( OR=1.415,95% CI: 0.866 to 2.312, P=0.017) and organ failure ( OR=1.256,95% CI: 1.015 to 1.554, P=0.036). Among HTG-AP patients,risk factors for SAP included body mass index ( OR=1.856,95% CI: 1.742 to 1.987, P=0.033),fasting blood glucose ( OR=1.128,95% CI: 1.036 to 1.229, P=0.006),white blood cell count( OR=1.162,95% CI: 1.055 to 1.281, P=0.002),and the presence of pleural effusion ( OR=13.151,95% CI: 4.330 to 19.946, P<0.01). A nomogram prediction model for SAP in HTG-AP was constructed based on these risk factors,demonstrating good discriminative ability with area under the curve values of 0.877 in the training set and 0.894 in the validation set,along with satisfactory calibration. Conclusions:HTG-AP patients are at higher risk of developing SAP and organ failure. The risk prediction model incorporating body mass index,fasting blood glucose,white blood cell count,and pleural effusion shows good predictive value for SAP.

Non-invasive body fluids contain a wealth of health-related biomarkers.Monitoring these biomarkers can provide valuable information for disease diagnosis,health management,drug abuse screening,and sports performance optimization.In this work,a carbon nanotube-polysiloxane(CNT-Putty)-based wearable electrochemical sensor was constructed on glove by screen-printing method.This electrode material had not only a simple composition,but also a relatively simple synthesis process.In addition,the electrode exhibited superior electrochemical performance compared to commercial screen-printed electrodes.When applied to uric acid(UA)detection in three different body fluids,the CNT-Putty working electrode demonstrated excellent linearity,selectivity,and a low detection limit.The wearable glove sensor could successfully monitor UA levels in body fluids under varying dietary conditions,indicating its potential for personalized UA monitoring and management.

Objective:To understand the current status of thyroid 131I internal exposure of nuclear medicine staff in Jiangxi province and analyze its influencing factors. Methods:An survey was conducted for the years 2022 to 2023, involving 211 nuclear medicine staff who had received 131I treatment in Jiangxi province. The 131I activity in thyroid was measured by in vitro monitoring measurement, and the committed effective dose was estimated. Results:In 2022, 14 nuclear medicine staff were detected to have 131I in thyroid, with activities ranging from 121.32 to 2 859.09 Bq, including four staff who were estimated to have received committed effective doses above 2 mSv. In 2023, there were 21 nuclear medicine staff who were detected to have 131I in thyroid, with activities ranging from 81.75 to 1 482.21 Bq, in which 10 staff were estimated to have the committed effective dose above 2 mSv. There were no statistically significant differences between the two years in detection rate, measured activity, and committed effective dose to thyroid from 131I ( P>0.05). The highest valure of detection rate was found in cleaning staff, and there were no statistically significant differences between different position types ( P>0.05). There was no statistically significant difference in the detection rate of 131I between those who only have received hyperthyroidism treatment and those who have received both hyperthyroidism and thyroid cancer treatment ( P>0.05). Conclusions:The issue of internal exposure of nuclear medicine staff should receive attention. It is necessary to further carry out internal exposure monitoring. Meanwhile, it is suggested that the management of radiation protection should be strengthened in nuclear medicine workplaces on the part of hospitals.

Lean six sigma (LSS) emphasizes patient demand-oriented, and continuously optimizing prolesses to achieve efficiency and standardization in medical services. Starting in 2021, a specialized children′s hospital (comprising one main campus and three branch campuses) introduced the LSS management method. Through define, measure, analyze, improve, and control, the hospital utilized tools such as questionnaire surveys, SIPOC models, and fishbone diagrams to identify pain points in the building of multi-campus child-friendly hospital and develop improvement measures.To address the main issues of insufficient cross-campus collaboration, significant disparities in service quality among different campuses, unclear functional positioning of each campus, and inadequate integration with social security mechanisms, the hospital implemented a " homogeneity-differentiation-coordination" management mode. The hospital implemented unified diagnosis and treatment standards and clinical pathways, carried out remote consultations and expert rotations, completed mutual recognition of examination and testing results, optimized child friendly labeling and child friendly environment, and built a " hospital-to-hospitals, hospital to medical schools, and hospital to community health centers" linkage platform, etc., to promote the standardization of diagnosis and treatment processes, clear functional positioning of the hospital area, and efficient resource allocation. Through practice, the outpatient appointment rate and patient satisfaction rate in the main hospital had increased from 86.72% and 98.64% in January December 2021 to 91.87% and 99.72% in January December 2024, respectively; The patient waiting time had been shortened from 26.54 minutes to 21.94 minutes, and the efficiency of medical treatment and service experience had been significantly improved. As of 2024, mutual recognition of 214 inspection and testing items had been achieved cross hospital campuses, forming a collaborative pattern of " main hospital leading, campuses support, and resource complementarity", and significantly improving the level of collaboration and child friendly connotation among multi-campus. This practice explored the integration path of multi-campus collaborative governance and child-friendly services, which could provide reference and inspiration for the similar hospitals.

Cervical spinal cord injury without fracture-dislocation (CSCIWFD) is referred to as a special type of cervical spinal cord injury characterized by traumatic spinal cord dysfunction and no significant bony structural abnormalities on imagines. Duo to the high risk of missed diagnosis during the initial consultation, CSCIWFD may lead to progressive neurological deterioration or even complete paralysis, severely impacting patients′ prognosis. Currently, there are no established consensuses over the diagnosis and treatment of CSCIWFD, such as the lack of evidence-based standards for indications of non-surgical treatment and risk of secondary neurological injury, as well as debates over the optimal timing for surgical intervention and indications for different surgical approaches. To address these issues, the Spine Trauma Group of the Orthopedic Branch of the Chinese Medical Doctor Association organized experts in the relevant fields to formulate Diagnosis and treatment guideline for acute cervical spinal cord injury without fracture- dislocation in adults ( version 2025) . Based on evidence-based medicine and the principles of scientific rigor and clinical applicability, the guidelines proposed 11 recommendations covering terminology, diagnosis, evaluation treatment, and rehabilitation, etc., aiming to standardize the management of CSCIWFD.

Objective To study a method for determining the cumulative dose of low-energy neutrons ( < 100 keV) independently based on a CR-39 detector. Methods According to the theory of track etching kinetics, the differences in the tracks formed by low-energy neutrons or fast neutrons in a BN + CR-39 detector under broad-spectrum neutron irradiation were analyzed. A method was proposed to identify the tracks produced by low-energy neutrons under specific etching conditions while avoiding interference from fast neutron tracks. Results Experimental results demonstrated that the BN + CR-39 detector using TASTRAK PADC CR-39 track-detecting plastic could independently detect the tracks of low-energy neutrons when etched in a 6.25 mol/L NaOH solution for 1 h. The track density showed a good linear relationship with the ambient dose equivalent of low-energy neutrons, and the calibration coefficient was 0.0366 μSv·tr⁻¹·cm². Conclusion The BN + CR-39 detector proposed in this study demonstrated high sensitivity to low-energy neutrons. The track identification method can be used for effective and independent determination of the cumulative dose equivalent of low-energy neutrons.

Triple-negative breast cancer (TNBC) is aggressive, with high recurrence rates and poor prognosis. Paclitaxel (PTX) remains a key chemotherapeutic agent for TNBC, but its efficacy diminishes due to the emergence of drug resistance, largely driven by cancer stem-like cells (CSCs), vasculogenic mimicry (VM) formation and tumor immunosuppressive microenvironment (TIME). Pyruvate kinase M2 (PKM2) is highly expressed in TNBC, and is a potential target for TNBC treatment. In this study, we developed a biomimetic codelivery system using albumin nanoparticles (termed S/P NP) to co-encapsulate PTX and shikonin (SHK), a natural inhibitor of PKM2. By inhibiting PKM2, SHK suppressed β-Catenin signaling, thereby reversing CSC stemness and preventing VM formation. The S/P NP system exhibited tumor-targeting delivery effect and significantly inhibited TNBC growth and lung metastasis. Mechanistically, the treatment reversed epithelial-mesenchymal transition (EMT) and stem-like properties of TNBC cells, suppressed VM formation, and remodeled the TIME. It reduced immunosuppressive cells (M2 macrophages, MDSCs) while promoting anti-tumor immunity (M1 macrophages, dendritic cells, cytotoxic T cells, and memory T cells). This dual-action strategy holds promise for improving TNBC therapy by targeting CSCs, VM, and the immune microenvironment, and for overcoming PTX resistance and reducing metastasis.

OBJECTIVE: To explore the current research status and hotspots in the field of biomechanics of diabetic foot by bibliometric analysis methods. METHODS: Literatures related to biomechanics of diabetic foot published in the Web of Scienc Core Collection (WoSCC) from 1981 to 2024 were searched. CiteSpace software and R language bibliometrics plugin were used to conduct a visual analysis of annual publication volume of the literature, including publication volume of each country and region, the publication situation of authors and institutions, the citation situation of individual literature, and the co-occurrence network of keywords. RESULTS: Totally 996 literatures were included, and the number of published papers increased steadily. The United States (261 papers) and China (89 papers) were the top two countries in terms of the number of published papers. The mediating centrality of the United States was 0.94, and that of China was 0.01. Scholars such as Cavanagh and institutions like the Cleveland Clinic were at the core of research in this field. High-frequency keywords include plantar pressure (plantar pressure), diabetic foot (diabetic foot), ulceration (ulcer), etc. The research focuses on plantar pressure, ulcer formation and prevention, etc. CONCLUSION Biomechanical research on diabetic foot mainly focuses on the pressure distribution on the sole of the foot, callus formation, mechanical analysis of soft tissues on the sole of the foot, and the study of plantar decompression caused by Achilles tendon elongation. The research trend has gradually shifted from focusing on joint range of motion to gait and the design of braces and assistive devices, and has begun to pay attention to muscle strength, gait imbalance and proprioception abnormalities.

First recorded in an official medical book from the Northern Song Dynasty called Taiping Huimin Heji Ju Fang （Prescriptions of the Bureau of Taiping People's Welfare Pharmacy）， Xiaoyaosan has been developed and refined over generations and is preserved to this day. It specializes in soothing the liver，resolving stagnation，fortifying the spleen，and nourishing blood. In this study，ancient traditional Chinese medicine （TCM） books and contemporary studies were reviewed to obtain information on Xiaoyaosan using bibliometrics，including its historical development，dosage，origin，processing methods，decoction dosage，and ancient and modern indications. Furthermore，a question regarding the presence of Zingiberis Rhizoma Recens and Menthae Haplocalycis Herba in Xiaoyaosan was investigated，and a table of key information on Xiaoyaosan was compiled，providing references for developing Xiaoyaosan preparations. According to the weight and measurement system of the Song dynasty，the contemporary equivalent formulation of the decocted Xiaoyaosan consists of 20.65 g of Glycyrrhizae Radix et Rhizoma and 41.3 g of Angelica Sinensis Radix，Poria，Paeoniae Radix Alba，Atractylodis Macrocephalae Rhizoma，and Bupleuri Radix. The formulation is processed to obtain a mixed powder with a particle size of 10 mesh. For each dose，8.25 g of the mixed powder is combined with 1 g of unprocessed Zingiberis Rhizoma Recens and 0.62 g of Menthae Haplocalycis Herba in 300 mL of water. The mixture is decocted until the volume reaches 210 mL，and the residue is then removed，with no specific timing required for administration. After the processing，each dose consists of approximately 0.75 g of Glycyrrhizae Radix et Rhizoma and 1.50 g of Radix Angelica Sinensis，Poria，Paeoniae Radix Alba，Atractylodis Macrocephalae Rhizoma，and Bupleuri Radix. Ancient medical literature shows that Xiaoyaosan primarily treats blood deficiency and overstrain，specifically for symptoms including heat caused by blood deficiency and fatigue，irregular menstruation，headache，eye soreness，pain in the ribs and limbs，and emaciation and bone steaming. In the Qing Dynasty，ZHANG Lu clearly proposed the pathogenesis of liver depression，and since then，the use of Xiaoyaosan in treating various syndromes associated with liver depression has been highly praised by physicians in the Qing dynasty and modern times. Xiaoyaosan has a wide application in modern clinical practices，involving digestive diseases，gynecological diseases，psychological diseases，nervous system diseases，and otorhinolaryngologic diseases. Moreover，it is most commonly used to treat depression and other diseases complicated with depression，hyperplasia of the mammary gland，etc. The key information on Xiaoyaosan and its clinical applications in ancient and modern times investigated in the study could serve as a scientific reference for in-depth research and extended clinical applications of the prescription.
