ObjectiveTo explore the potential categories and characteristics of the public hospice care demand in Hainan Province, and analyze different potential types of influencing factors, so as to provide reference for relevant departments to improve the public awareness and demand of hospice care. MethodsUsing convenience sampling method, select 6484 cities of the public as the survey object, using the general data questionnaire, the hospice care demand questionnaire of the potential profile analysis, and analyze the influencing factors of the public hospice care demand category. ResultsThe characteristics of the hospice care demand in Hainan Province were divided into three potential categories: low demand group (14.19%), medium demand group (49.99%) and high demand group (35.82%). Multivariate analysis showed that gender, age, education level, cultural belief, and life-death education experience were the main influencing factors of public hospice care demand (p<0.05). Males, those aged 41-60 years, and those with high school education or below had relatively lower hospice care demand, while those with life-death education experience had relatively higher demand. ConclusionRelevant departments should focus on hospice care knowledge popularization and demand enhancement for males, middle-aged groups, and people with low education levels, while strengthening universal life-death education through stratified and classified publicity strategies and educational interventions to improve different populations’ awareness and acceptance of hospice care.

ObjectiveMigraine is a leading neurological disorder and the fourth most common cause of years lived with disability worldwide, affecting nearly 116 million individuals. Although pharmacological treatments are available, their efficacy is often limited by side effects and variable response rates. Repetitive transcranial magnetic stimulation (rTMS) over the dorsolateral prefrontal cortex (DLPFC) offers a safe, non-invasive alternative for migraine management. However, the neurophysiological mechanisms, particularly how rTMS modulates local cortical excitability and distributed pain-related circuits, remain poorly understood. Elucidating these mechanisms is essential for optimizing treatment protocols and improving clinical outcomes. MethodsThis study employed concurrent transcranial magnetic stimulation and electroencephalography (TMS-EEG) to investigate neuroplastic and neurocircuitry mechanisms of DLPFC-rTMS in migraine. Study 1 compared 30 migraineurs and 28 healthy controls to identify abnormalities in TMS-evoked potentials (TEPs) and significant current density (SCD) within sensory-discriminative regions including the primary somatosensory cortex (S1) and posterior insula (pINS), cognitive-affective regions including the anterior insula (aINS) and midcingulate cortex (MCC), and a descending modulatory region, the periaqueductal gray (PAG). Study 2 used a single-blind, crossover, sham-controlled design in 34 healthy participants. Each participant received both active (10 Hz, 80% RMT, 1 500 pulses) and sham DLPFC-rTMS in counterbalanced order. TMS-EEG and cold pain tolerance were assessed before and after each session. ResultsIn Study 1, migraineurs showed a significantly less negative N120 amplitude compared to healthy controls (P=0.027, Cohen’s d=0.60), indicating local intracortical disinhibition. No group differences were observed for N40, P60, or P180 components. At the source level, migraineurs exhibited significantly higher SCD in the S1, pINS, aINS, and MCC (allQ<0.05), but not in the ventroposterior thalamus (vpTHAL), mediodorsal thalamus (mdTHAL), or PAG. In Study 2, active rTMS significantly reduced SCD from pre- to post-stimulation in the S1, aINS, and MCC (all Q<0.05). Sham stimulation also reduced SCD in the S1 (Q<0.05) but not in the aINS or MCC. Although no significant group-level analgesic effect was observed between active and sham conditions (P=0.107), correlation analyses revealed that greater SCD reductions in the S1 and MCC were significantly associated with higher post-rTMS pain tolerance (R=-0.487 and -0.495, both Q<0.01) and larger improvements in pain tolerance(R=-0.487 and -0.451, both Q<0.05). No such correlations were found following sham stimulation, suggesting that the behavioural relevance of neural changes is specific to active rTMS. ConclusionThis study provides novel evidence that migraineurs exhibit both local neuroplastic abnormalities (reduced N120 amplitude) and hyperactivity in key pain-processing regions (S1, pINS, aINS, MCC). A single session of DLPFC-rTMS reduced hyperactivity in the aINS, MCC, and S1. Notably, greater reductions in the S1 and MCC were associated with improved pain tolerance. These findings identify distinct cortical circuitries, particularly within the cognitive-affective pain network, that may serve as potential biomarkers for optimizing rTMS treatment in migraine and other chronic pain conditions. Future studies should validate these results in patient populations experiencing spontaneous migraine attacks and explore multi-session or accelerated rTMS protocols.

ObjectiveTo evaluate the clinical efficacy and safety of Xiaozhen Formula (消疹方) in preventing skin toxicity induced by epidermal growth factor receptor inhibitors (EGFRIs) in patients with EGFR-mutant non-small cell lung cancer (NSCLC). MethodsA randomized, double-blind, placebo-controlled, multicenter clinical study was conducted. A total of 120 patients with EGFR-mutant NSCLC from seven centers were enrolled and randomly assigned to a treatment group (60 cases) or a control group (60 cases). On the basis of EGFRI-targeted therapy, patients in the treatment group received Xiaozhen Formula granules, whereas those in the control group received Xiaozhen Formula placebo granules, both at 10 g twice daily for 4 consecutive weeks. The primary outcomes were the grading of skin toxicity evaluated using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0 and the incidence of rash. Secondary outcomes included the time to onset and time to resolution of the highest-grade rash, the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) scores, the Hospital Anxiety and Depression Scale (HADS) scores, and disease control rate, together with safety assessments. ResultsBased on the full analysis set (FAS), the incidence of skin toxicity in the treatment group was 18.33% (11/60), significantly lower than 45.00% (27/60) in the control group (P<0.01), with the highest severity of skin toxicity in both groups was grade 2. Among patients who developed rash, the resolution rate in the treatment group was 90.91% (10/11), higher than that 33.33% (9/27) in the control group. The median time to resolution was 15 days (95%CI: 8-17 days) in the treatment group and it was not reached in the control group; the distribution of time to resolution differed significantly between groups (P<0.001). After treatment, the treatment group had higher EORTC QLQ-C30 functional scale and global health status/quality-of-life scores, and lower symptom scale, single-item scores, as well as HADS-A, and HADS-D scores than the control group (P<0.05). In the FAS analysis, the disease control rate (DCR) was 85.0% (51/60) in the treatment group, lower than 100.0% (60/60) in the control group (P=0.003), whereas no significant between-group difference was observed in the per-protocol set (PPS) analysis (P=0.464). The incidence of adverse events did not differ significantly between the two groups (P>0.05), and no definite safety signals related to the investigational drug were observed. ConclusionXiaozhen Formula can reduce the incidence of EGFRI-induced skin toxicity, and improve the outcome of rash regression, the patients' quality of life and psychological status in EGFR-mutant NSCLC patients.

Aim To investigate the protective effects and potential mechanisms of Radix Angelica sinensis and Radix Hedysari ultrafiltrate(RAS-RH)on X-ray-induced cellular damage in Raw264.7 macrophages.Methods An integrated approach combining network pharmacology,molecular docking,and bioinformatics a-nalysis was employed to predict therapeutic targets and signaling pathways of RAS-RH in coronary heart dis-ease(CHD).Subsequent in vitro validation was per-formed using an X-ray(6 Gy)-induced macrophage in-jury model with four experimental groups:control,radi-ation-only model,and three RAS-RH-treated groups at varying concentrations.Cell viability was assessed by CCK-8 assay,apoptosis by flow cytometry with Annexin V-FITC/PI staining,mitochondrial membrane potential by JC-1 fluorescence,and inflammatory cytokine levels(IL-1 β,IL-6,IL-18,TNF-α)by ELISA.Molecular mechanisms were investigated through Western blot and qRT-PCR analyses of TLR4/NLRP3/Caspase-1 sig-naling pathway components and Bcl-2 family proteins.Results Network pharmacology revealed RAS-RH's multi-target action on apoptosis and inflammation-relat-ed pathways,particularly NF-κB and Bcl-2 signaling.Molecular docking identified strong binding affinities between RAS-RH components and TLR4/NLRP3 pro-teins.In vitro studies demonstrated that RAS-RH treat-ment significantly improved cell viability(P<0.01),reduced apoptosis(P<0.01),restored mitochondrial membrane potential(P<0.05),and attenuated radia-tion-induced ultrastructural damage including mem-brane disruption and cytoplasmic vacuolization.ELISA showed marked suppression of pro-inflammatory cyto-kines(P<0.01).Transmission electron microscopy(TEM)analysis revealed that RSA-RH ameliorated pyroptosis-associated ultrastructural alterations,inclu-ding plasma membrane disruption and cytoplasmic vac-uolization.Protein and gene expression analyses con-firmed downregulation of TLR4/NLRP3/Caspase-1 pathway and modulation of Bcl-2/Bax ratio.Conclu-sion RAS-RH exerts radioprotective effects through dual regulation of pyroptosis and apoptosis pathways,suggesting its potential as an adjuvant therapy for radia-tion-induced cardiovascular complications in CHD pa-tients.

Travelling wave structures for lossless ion manipulations(TW-SLIM)employ travelling wave electric fields to propel ions forward,enabling exceptionally long transmission paths and holding great potential for applications in material transportation and separation.In this study,different from previous studies focusing on the transport performance of macromolecules such as proteins in TW-SLIM,the transmission performance of small molecules(<200 amu)was investigated and analyzed in the turning TW-SLIM through the COMSOL simulation platform,to explore the influence of electrostatic field of protective electrode and radio frequency(RF)electric field on ion transport efficiency,and obtain the optimal value.Compared to macromolecules,small molecules required lower voltage amplitudes from guard electrodes but stricter requirements in terms of the peak-to-peak amplitude and frequency of RF voltage for lossless transmission.Using dimethyl methylphosphonate(DMMP)as a sample and testing it on the TW-SLIM experimental platform,when the protective voltage amplitude was 5 V and the peak-to-peak voltage of the radio-frequency electrode was 440 V at 1.5 MHz,the ion transmission efficiency reached 100%,achieving lossless transmission.The experimental results provided valuable references for application of TW-SLIM in separation and detection of small molecular substances,such as explosives and drugs.

BACKGROUND:The asymmetrical biomechanical environment of adolescent idiopathic scoliosis can lead to further wedge deformation of the vertebral body,which may affect cardiopulmonary function and compress nerves in severe cases.Adolescent idiopathic scoliosis with different degrees of scoliosis should be treated with exercise,bracing,and surgery.However,the mechanical mechanism of selecting an orthopedic approach remains unclear due to the individual variability of patients.OBJECTIVE:To investigate the biomechanical mechanism of different orthopedic modalities for the treatment of adolescent idiopathic scoliosis to provide a basis for clinical selection of treatment modalities based on the spine model of adolescent idiopathic scoliosis patients.METHODS:Based on the CT images of an adolescent idiopathic scoliosis patient,a scoliosis model(C7-L5)was reconstructed in Mimics software in three dimensions,and lateral thrust force was applied at the T8/T9 thorax and vertical distraction force was applied over the C7 vertebra with the magnitude of 20,40,60,80,100,and 120 N.The intervertebral disc stress and vertebral displacement in concave and convex sides,and Cobb angle of the spine were analyzed under two orthopedic modalities.RESULTS AND CONCLUSION:(1)With lateral thrust,there was no significant change in the C7T1-T7T8 intervertebral disc.The concave and convex stress of T7T8-L4L5 segment decreased first and then increased with the increase of lateral thrust force.The correction effect of lateral thrust on the segment near T8T9 was obvious and weakened with the extension of the segment to the cephalic and caudal ends.At 120 N of lateral thrust,the thoracic Cobb angle changed from 53.2° to 32.5° and the lumbar Cobb angle changed from 50.2° to 43.9°.(2)With the vertical distraction,the thoracic intervertebral disc stresses first decreased and then increased,and all the lumbar disc stresses decreased.The C7 displacement was the most obvious,and the correction effect gradually diminished with the segment extended to the caudal end.At a vertical distraction force of 120 N,the thoracic Cobb angle changed from 53.2° to 39.4° and the lumbar Cobb angle changed from 50.2° to 47.6°.(3)It is concluded that both orthopedic modalities provide improvement in the degree of scoliosis,with the thoracic correction being greater than the lumbar correction.Also,the asymmetric stress distribution on the concave and convex sides is improved,which contributes to normal bone growth.A vertical distraction approach is appropriate for larger Cobb angles,and a lateral thrust approach is appropriate for smaller Cobb angles.The results of this study help to understand the mechanism of spinal orthosis and provide a theoretical basis for the choice of orthopedic approach.
