Data for demographic data, spirometry and exhaled nitric oxide were collected for comparative analysis, correlation analysis and discriminant canonical analysis.Results: The values of FENO200 in asthma, COPD and ACO groups were 11.0(7.0– 22.3), 8.0(6.0– 11.0) and 9.0(6.5– 19.5) ppb, respectively. In the asthma group, FENO200 exhibited negative correlations with FEV1/FVC, MMEF and MEF50. No significant correlation was observed between CANO and pulmonary function parameters. In the COPD group, both FENO200 and CANO showed negative correlation with pulmonary function parameters including FVC, FEV1, PEF, MMEF, MEF75, MEF50. In the ACO group, FENO200 demonstrated no significant correlation with pulmonary function parameters, while CANO was correlated with FEV1, PEF, MMEF and MEF50. In COPD group, ΔFEV1 in the bronchodilator test was correlated with FENO200. As for the ACO group, ΔFEV1 was correlated with CANO. In the discriminant canonical analysis, four parameters including gender, age, MEF75 and FENO50 discriminated between the three groups of asthma, COPD and ACO.Conclusion: In asthma, COPD and ACO, FENO200 has demonstrated a robust correlation with CANO. Elevated FENO200 levels are predominantly indicative of pulmonary function impairment in asthma and COPD, whereas elevated CANO levels are mainly correlated with pulmonary function impairment in COPD and ACO. Compared with FENO200 and CANO, FENO50 may have a better discriminatory ability in distinguishing asthma, COPD and ACO.Keywords: FENO200, CANO, ACO, asthma, chronic obstructive pulmonary disease

Recent studies have reported that electroacupuncture (EA) can treat osteoporosis, but most of which were based on the “kidney governing bones” theory. However, the ancient Chinese medical textbook Huangdi Neijing pointed out that “Gallbladder Meridian of Foot Shaoyang” correlates with bone diseases, including osteoporosis, although the therapeutic regimens were lost after the Tang Dynasty. Here, we explored whether EA at GB points improves osteoporosis and its underlying mechanism. We constructed ovariectomized mice and treated them with EA at GB30 (Huantiao), GB34 (Yanglingquan), and GB39 (Xuanzhong) acupoints. EA treatment significantly improved bone parameters in osteoporotic mice, as evidenced by micro-computed tomography and histological assessment. Additionally, EA treatment elevated the serum levels of estradiol and SOD that were downregulated in osteoporotic mice. Transcriptome and qPCR results verified that EA treatment upregulated the expression of genes associated with bone formation. Moreover, transcriptome analysis revealed differential enrichment of the PI3K–Akt pathway. Furthermore, Western blot analysis demonstrated that estradiol partially counteracted a reduction in p-AKT expression induced by hydrogen peroxide. These findings indicate that EA treatment increases serum estradiol levels in mice, thus inhibiting osteoporosis induced by oxidative stress. This effect is achieved by activating the PI3K–Akt signaling pathway.

Nanofluid, a significant branch of fluid mechanics, plays a pivotal role in thermal management, optics, biomedical engineering, energy harvesting, and other fields. The nanoparticles present in the fluid render the continuum mechanics ineffective, necessitating the adoption of fractional calculus to elucidate the effects of nanoparticles on the motion properties of the nanofluid. This article applies the modified extended tanh-function technique to solve two classical Schrödinger equations, the fractional Phi-4 model and the conformable fractional Boussinesq model, for nanofluids. Multiple exact solutions are obtained, and the corresponding graphical representations are provided to elucidate the basic properties of the nanofluid. This article provides new research perspectives for the development of nanofluids.

This study aims to elucidate the effects of a combination of remimazolam and esketamine vs propofol and esketamine on hemodynamic parameters in elderly patients undergoing painless colonoscopies.Patients and Methods: We conducted a randomized controlled trial involving 754 patients, divided equally between two treatment groups. The remimazolam-esketamine group (RE group) received 0.15 mg/kg of remimazolam and 0.3 mg/kg of esketamine. Conversely, the propofol-esketamine group (PE group) was administered 1.5 mg/kg of propofol with 0.3 mg/kg of esketamine. Primary outcomes focused on the incidence of hypotension. Secondary outcomes assessed were other hemodynamic adverse events, intraoperative blood pressure and heart rate fluctuations, usage of vasoactive agents, sedation efficacy, and additional adverse reactions.Results: Hypotension occurred significantly less frequently in the RE group (9.78%, 95% confidence interval[CI]: 6.67– 12.87%) compared to the PE group (23.57%, 95% CI: 21.22– 30.52%), P< 0.001. The RE group also showed lower incidences of sinus tachycardia, sinus bradycardia, and required less support from vasoactive agents (P< 0.001). Additionally, the RE group experienced smaller fluctuations in blood pressure and heart rate (P< 0.05). Both groups achieved a 100% sedation success rate. Notably, the RE group had a longer induction period but a quicker recovery time (P< 0.001), and lower rates of respiratory depression (P=0.006) and injection pain (P< 0.001).Conclusion: Remimazolam combined with esketamine offers superior hemodynamic stability and significantly reduces adverse event rates compared to propofol plus esketamine in elderly patients undergoing painless colonoscopies, while maintaining effective sedation.Keywords: remimazolam, esketamine, colonoscopy, elderly patients, hemodynamic effects

A novel genus, Paradingleyomyces was introduced to accommodate Pa. lepidopterorum sp. nov., based on a multigene phylogenetic analysis and its distinct morphological characteristics. Maximum likelihood (ML) and Bayesian inference analyses (BI) of ITS, SSU, LSU, tef-1α, rpb1, and rpb2 sequence data shown that Pa. lepidopterorum formed an independent lineage nested between Perennicordyceps and Dingleyomyces. Morphologically, Paradingleyomyces is distinguished from Perennicordyceps by the presence of a white subiculum on the stromata of Ophiocordyceps cf. cochlidiicola. Perithecia are produced sporadically from the base to the apex of the stromata, and the secondary ascospores exhibit a notable length-to-width ratio. These characteristics distinguish Paradingleyomyces from Perennicordyceps which exhibits tortuous, branched, clavate to cylindrical stromata with rhizomorphs, parasitism of coleopteran and hemipteran larvae, and colonizes a broader range of fungal hosts. Additionally, perithecia in Perennicordyceps typically arise from the middle to the upper regions of the stromata, with secondary ascospores displaying a comparatively lower length-to-width ratio. Paradingleyomyces is morphologically identical to Dingleyomyces in its direct production of superficial perithecia on the stromata of Ophiocordyceps species. However, the phylogenetic analysis indicates that Paradingleyomyces and Dingleyomyces are not congeneric. Moreover, this study introduces another novel species, Polycephalomyces tengchongensis, and a novel sexual morph of Pleurocordyceps yunnanensis. Dimorphic phialides and conidia of Pleurocordyceps parvicapitata were observed and described for the first time based on a fresh collection from Tengchong County, Yunnan Province, China.

Abstract Objective This study aims to examine the relationship and mechanism between sense of self and nonsuicidal self-injury among college students, providing a new theoretical basis for predicting and preventing such behavior. Methods A total of 1350 college students completed the Sense of Self scale, nonsuicidal self-injury questionnaire, frustration scale, and social problem-solving questionnaire. Results (1) Negative Sense of Self predicts frustration, and frustration positively predicts nonsuicidal self-injury. (2) Frustration serves as a partial mediator in the relationship between sense of self and nonsuicidal self-injury. (3) The impulsive-negligent social problem-solving style regulates the first half of the mediation model by influencing the relationship between sense of self and frustration. Conclusion Frustration, mediated by sense of self, increases the risk of nonsuicidal self-injury, and this relationship is moderated by the impulsive-negligent social problem-solving style. Sense of Self is a necessary but not sufficient condition for nonsuicidal self-injury, indirectly influencing such behavior through frustration triggered by stress events.

The patients and intervention of the two arms were modeled according to the CANDOR trial. Costs were collected from the Chinese health system perspective. One-way sensitivity analysis and probabilistic sensitivity analysis were performed to evaluate the robustness of our conclusions.Results: Compared with the Kd arm, KdD achieved an additional 0.537 quality-adjusted life-years (QALYs) at an incremental cost of &dollar;138,084, resulting in an incremental cost-utility ratios (ICURs) of &dollar;257,319 per QALY. Uncertainty analyses revealed that the model is robust to all the input parameters.Conclusion: From the Chinese healthcare system perspective, adding daratumumab to the Kd regimen for patients with RRMM appears to lack cost-effectiveness. Exploring alternative avenues such as negotiating for a more favorable price or introducing a financial assistance program dedicated to daratumumab and/or carfilzomib could prove to be an effective strategy in enhancing accessibility of this combination.Keywords: cost-effectiveness, daratumumab, multiple myeloma, Markov model, China

Childhood trauma is a distal factor for NSSI and can also lead to cognitive abnormalities and maladaptive emotion regulation during the growth and development of individuals. However, it is unclear how childhood trauma and cognitive-emotional factors interact with NSSI.Objective: This study investigated the roles of childhood trauma and cognitive-emotional factors in NSSI among Chinese college students using network analysis.Methods: A total of 999 students from a university in central China were included in this study. Network analysis was used to examine the interrelationships between the frequency of NSSI thoughts and behaviors, childhood trauma subtypes (measured using the Childhood Trauma Questionnaire-Short Form), and cognitive-emotional factors such as early maladaptive schemas (EMSs) (measured using the Young Schema Questionnaire-Short Form), core self-evaluation (measured using the Core Self-Evaluations Scale), and emotion regulation (ER) strategies (measured using the Emotion Regulation Questionnaire). Structural equation modeling was used to further explore the role of the nodes most closely related to NSSI in the network analysis.Results: Emotional abuse and disconnection/rejection EMS are found to be directly related to NSSI thoughts (edge weight = 0.16 and 0.08, respectively). Disconnection/rejection EMS partially mediated (28.64%) the relationship between emotional abuse and NSSI thoughts, with a higher level of expression suppression corresponding to a greater positive relationship between emotional abuse and the disconnection/rejection EMS (p < 0.01).Conclusion: Our findings were in line with the cognitive-emotional model of NSSI, highlighting the importance of NSSI prevention in identifying risk groups who experienced emotional abuse in childhood and tended to use expressive suppression as an ER strategy.Keywords: childhood trauma, early maladaptive schema, emotion regulation strategy, non-suicidal self-injury, network analysis

Participants were divided into two groups: the IVF/ICSI-ET group (204 cases) and the spontaneous conception (SC) group (1558 cases). After 1:2 propensity score matching (PSM), the two groups were compared for maternal and neonatal outcomes. The SC group (1558 cases) was further divided by age into the < 43 years group (1195 cases) and the ≥ 43 years group (363 cases) for subgroup analysis.Results: Adverse maternal and neonatal outcomes were comparable between the IVF/ICSI-ET group and the SC group, with a higher cesarean section rate (78% vs 67.5%, P =0.013), an increased maternal ICU admissions rate (5.5% vs 1.3%, P =0.008), and a lower birth defects rate (1.1% vs 4.6%, P =0.037) in the IVF/ICSI-ET group. Subgroup analysis showed that women aged ≥ 43 years had higher incidences of gestational diabetes, gestational hypertension, cesarean section, and neonatal asphyxia compared to women aged < 43 years.Conclusion: This study indicated IVF/ICSI-ET is relatively safe for women ≥ 40 years with singleton pregnancies. However, advanced maternal age deteriorated maternal and neonatal outcomes, and IVF/ICSI-ET further heightened the risk of cesarean section and maternal ICU admissions. Therefore, enhanced care and vigilance are crucial for women over 40 undergoing IVF/ICSI-ET.Keywords: in-vitro fertilization, intracytoplasmic sperm injection, advanced maternal age, maternal outcomes, neonatal outcomes

However, the free-text format of MTB surgical records limits the formulation of effective postoperative patient management and rehabilitation plans. This study compares the efficacy of large language models (LLMs) in structuring data from these free-text MTB surgical record.Methods: This retrospective study collected a total of 382 MTB surgical records from a tertiary hospital. An initial analysis of 30 surgical record from these records provided a guiding prompt for LLMs, focusing on basic and advanced characteristics, such as occlusion locations, thrombectomy maneuvers, reperfusion status, and intraoperative complications. Six LLMs—ChatGPT, GPT-4, GeminiPro, ChatGLM4, Spark3, and QwenMax—were assessed against data extracted by neuroradiologists and a junior physician for comparison. The all 382 surgical records were used to test the performance of LLMs. The performance of the LLMs was quantified using Accuracy, Sensitivity, Specificity, AUC, and MSE as an additional metric for advanced characteristics.Results: All LLMs showed high performance in characteristic extraction, achieving an average accuracy of 95.09 ± 4.98% across 48 items, and 78.05 ± 4.2% overall. GLM4 and GPT-4 were most accurate in advanced characteristics extraction, with accuracies of 84.03% and 82.20%, respectively. The processing time for LLMs averaged 73.10 ± 10.86 seconds of six models, significantly faster than the 427.88 seconds for manual extraction by physicians.Conclusion: LLMs, particularly GLM4 and GPT-4, efficiently and accurately structured both general and advanced characteristics from MTB surgical record, outperforming manual extraction methods and demonstrating potential for enhancing clinical data management in AIS treatment.Keywords: large language models, free-text report, mechanical thrombectomy, acute ischemia stroke

The Fugl–Meyer Assessment was used to assess functional impairment. Serum irisin levels were measured using the enzyme-linked immunosorbent assay method. Multivariate logistic regression was employed to explore the factors related to serum irisin levels and AIS.Results: Serum irisin levels in the AIS group were significantly lower than those in the control group. However, no significant association was observed between serum irisin and stroke severity within the AIS cohort. Multivariate logistic regression analysis revealed an inverse correlation between serum irisin levels and AIS risk, indicating that it serves as a protective factor against AIS. The increase in serum irisin levels (adjusted odds ratio (OR) 0.938, 95% confidence interval [CI]: 0.899– 0.977 per 100 pg/mL increment) was associated with a decreased risk of AIS. Analysis of the receiver operating characteristic curve confirmed the diagnostic value of serum irisin for AIS, with the area under the curve being 0.591 (95% CI: 0.522– 0.659, p = 0.012).Conclusion: Serum irisin levels were significantly lower in AIS and were identified as a protective factor, suggesting that serum irisin may have diagnostic value for AIS.Keywords: irisin, acute ischaemic stroke, hemiplegia, risk factors, predictive value

Gain-of-function SYK variants have been implicated in pediatric inflammatory bowel diseases. This study aimed to investigate the effects of gain-of-function SYK variants on the susceptibility to experimental colitis and macrophage function.Methods: Colitis was induced using dextran sodium sulfate and dinitrobenzene sulfonic acid in mice harboring a gain-of-function variant in SYK (SykS544Y). Intestinal inflammation was assessed via disease activity index, histological analysis, and Western blotting. The frequencies of macrophages, phagocytosis, and reactive oxygen species (ROS) production in bone marrow-derived macrophages (BMDM) were measured via flow cytometry. Chemokines and BMDM chemotaxis were analyzed using real-time quantitative reverse transcription polymerase chain reaction and Transwell assays. The expression of nucleotide-binding domain leucine-rich-containing family, pyrin domain-containing-3 (NLRP3) inflammasome-related proteins were detected using immunohistochemistry, enzyme-linked immunoassay and Western blotting.Results: SykS544Y mice exhibited increased susceptibility to experimental colitis, and macrophage infiltration in colon tissues significantly increased. We observed increased expression of macrophage chemokines in colon tissues and enhanced chemotaxis in SykS544Y BMDM. Additionally, we detected increased levels of fluorescent microspheres and 2.7-dichloride-hydro fluorescein diacetate-labeled ROS in SykS544Y BMDM. Moreover, enhanced levels of NLRP3 inflammasome-related proteins were observed in the colon tissues and BMDM from SykS544Y mice.Conclusion: Gain-of-function variant in SYK may contribute to the pathogenesis of pediatric inflammatory bowel diseases by promoting macrophage migration, phagocytosis, ROS production and activation of NLRP3 inflammasomes.Keywords: inflammatory bowel disease, SYK, gain-of-function variant, macrophage

In the univariate logistic regression analysis, thirty-six out of 46 risk factors, including 34 laboratory markers, were significantly associated with increased odds of severe patients. Multivariate logistic regression analysis showed that the CD19+ lymphocyte count, MYO, LDH, and AFR were associated with increased odds of severe disease. Moreover, Lymphocyte count and AFR levels increased, LDH and CRP levels decreased during hospitalization in recovered severe patients, whereas severe lymphocytopenia and continuously increasing LDH levels were observed in deteriorated patients. AFR level increased and CRP level decreased before the disease worsened in the deteriorated patients; however, when the patients deteriorated, AFR decreased and CRP increased significantly.Conclusion: CD19+ lymphocyte count, MYO, LDH, and AFR are independent biomarkers for early identification of severe COVID-19. Lymphocyte count, AFR, LDH, and CRP levels were helpful in predicting the clinical progression of the disease.\.

While the role of inflammatory and immune factors in GLM has been recognized, a comprehensive clinical evaluation of these markers is still lacking. This study aims to identify potential diagnostic markers and therapeutic targets by comparing immune markers and cytokine levels in GLM patients and healthy controls.Methods: Conducted at Beijing Hospital of Traditional Chinese Medicine, Capital Medical University from July 2023 to May 2024, this study enrolled 30 GLM patients and 15 healthy female controls in a 2:1 ratio. Serum levels of immune markers and cytokines were analyzed to explore their potential association with GLM.Results: The study population comprised 30 GLM patients with a mean age of 33.40 ± 4.12 years and 15 healthy female controls with a mean age of 32.13 ± 6.19 years. Significantly elevated levels of C-reactive protein (CRP), Immunoglobulin A (IgA), Complement Component 3 (C3), Complement Component 4 (C4), Compliment Component 1q (C1q), Alpha1-antit-rypsin (AAT), α 1-acidglycoprotein (AGP), Anti-histone antibodies (Anti-HIS), Anti-Ro52 antibodies (Anti-Ro52), Anti-double stranded DNA antibodies (Anti-dsDNA), Interleukin-6 (IL-6), Interleukin-10 (IL-10), and Tumor Necrosis Factor-α (TNF-α) were observed in GLM patients compared to controls (all P < 0.05). Subgroup analysis revealed higher levels of CRP, C3, C1q, AAT, and AGP in patients with larger mass areas and those with erythema nodosum (all P < 0.05). No significant differences were found in subgroups based on disease duration or recurrence (both P > 0.05).Conclusion: Serum levels of CRP, IgA, AAT, AGP, Anti-HIS, Anti-Ro52, Anti-dsDNA, C3, C4, C1q, IL-6, IL-10, and TNF-α may serve as diagnostic and prognostic indicators for GLM, with CRP, AAT, AGP, and C1q being particularly indicative of disease severity. These markers offer potential therapeutic targets for GLM.Keywords: granulomatous lobular mastitis, peripheral serology, immune markers, cytokine

Abstract The dynamic crack propagation trajectories play a crucial role in enhancing our understanding of spatial mechanisms involved in crack expansion. However, visualization of internal cracks under complex crack conditions has always been a challenge. Biological networks have been honed by many cycles of evolutionary selection pressure and are likely to yield reasonable solutions to such combinatorial optimization problems. This study applied the slime mould algorithm to improve the accuracy of internal crack localization in rocks and employed Minimum spanning tree and Gaussian mixture model to construct the crack propagation trajectories. By introducing the concept of bond length, the evolution characteristics of crack levels were effectively characterized. Research results showed that this approach effectively preserves essential crack localization information while mitigating the influence of interfering parameters, providing crack characterization results that exhibit high consistency with actual fracture patterns. The curves of cumulative bond length and relative bond length over time conform to the trend of a Growth/Sigmoidal curve. The strength of the bond was correlated with the temporal process of crack propagation. This result could be helpful for analyzing crack trajectories and predicting rock stability.

Abstract Branching networks are key elements in natural landscapes and have attracted sustained research interest across the geosciences and numerous intersecting fields. The prevailing consensus has long held that branching networks are optimized and exhibit fractal properties adhering to power-law scaling relationships. However, tidal networks in coastal wetlands and mudflats exhibit scaling properties that defy conventional power-law descriptions, presenting a longstanding enigma. Here we show that the observed atypical scaling represents a universal deviation from an ideal fractal branching network capable of fully occupying the available space. Using satellite imagery of tidal networks from diverse global locations, we identified an inherent “laziness” in this deviation—where the increased ease of channel formation paradoxically decreases the space-filling efficiency of the network. We developed a theoretical model that reproduces the ideal fractal branching network and the laziness phenomenon. The model suggests that branching networks can emerge under a localized competition principle without adhering to conventionally assumed optimization-driven processes. These results reveal the dual nature of branching networks, where “laziness” complements the well-known optimization process. This property provides more flexible strategies for controlling tidal network morphogenesis, with implications for coastal management, wetland restoration, and studies in fluvial and planetary systems.

Abstract Saccharomyces cerevisiae L7 was found to be an excellent starter and biological deacidification strain for Suanyu, however, the underlying mechanisms remain poorly understood. This study aimed to investigate the acid inhibition mechanism of S. cerevisiae L7. The strain enhances the sensory and flavor characteristics of Suanyu. The growth of Lactiplantibacillus plantarum is inhibited due to competition for carbon sources, resulting in a decrease in cell count from 9.00 Lg CFU/mL at 48 h to 7.70 Lg CFU/mL in co-culture. The addition of yeast reduces acidity, decreasing it from 5.83 g/kg to 0.82 g/kg at 48 h, while increasing sugar utilization to 94.52%. We found that cell contact was the main method of inhibition between the two microbials. Transcriptome analysis revealed that multiple pathways were affected under co-culture, ultimately leading to a decrease in lactic acid production. These findings provide valuable insights into the microbial interactions involved in biological deacidification.

WHONET 5.6 was used to analyze the results.Results: A total of 2444 culture samples were received, predominantly sputum (34.66%) and blood (23.36%) samples, with a steady annual increase in specimen types. A total of 572 pathogenic strains were isolated, predominantly from respiratory specimens (54.02%), including 345 Gram-negative bacteria (60.31%), 135 Gram-positive cocci (23.60%), and 92 fungi (16.08%). The most frequent pathogens included Acinetobacter baumannii (30.77%), Candida albicans (11.71%), and Klebsiella pneumoniae (9.97%). Drug sensitivity tests indicated a fluctuating resistance rate of Acinetobacter baumannii over the past five years. Staphylococcus aureus displayed strong in vitro activity against vancomycin, tigecycline, and linezolid, with no resistant strains identified. The detection rates of carbapenem-resistant Acinetobacter baumannii (CR-AB), carbapenem-resistant Pseudomonas aeruginosa (CR-PA), methicillin-resistant Staphylococcus aureus (MRSA), and strains producing extended-spectrum beta-lactamases (ESBL) were 86.78%, 26.79%, 32.45%, 70.27%, and 23.54%, respectively.Conclusion: Compared with other countries in the world, China has increased its data on the prevalence of MDR pathogens and antibiotic resistance.The high resistance rate of Acinetobacter baumannii in the ICU underscores the need for effective infection control measures. Enhanced monitoring of CR-AB, ESBL-producing bacteria, and MRSA is essential, along with improved management of antibacterial drugs and the pursuit of new therapeutic options.Keywords: new-built hospital, intensive care unit, pathogens, multidrug-resistant bacteria, antimicrobial resistance

However, medical personnel and patients face significant obstacles in implementing exercise prescription recommendations. AI has been developed as a beneficial tool in the healthcare field. The performance of intelligent tools such as ChatGPT 4.0 and Intelligent Health Promotion Systems (IHPS) in issuing exercise prescriptions for patients with hypertension comorbidities remains to be verified.Patients and Methods: After collecting patient information through IHPS hardware and questionnaire systems, the data were input into the software terminals of ChatGPT 4.0 and IHPS according to the five stages of the Transtheoretical Model, resulting in exercise prescriptions. Subsequently, experts from various fields scored the accuracy, comprehensiveness, and applicability of each prescription, along with providing professional recommendations based on their expertise. By comparing the performance of both systems, their capability to serve this specific group was evaluated.Results: In most cases, ChatGPT scored significantly higher than IHPS in terms of accuracy, comprehensiveness, and applicability. However, when patients exhibited certain functional movement disorders, GPT’s exercise prescriptions involved higher health risks, whereas the more conservative approach of IHPS was advantageous.Conclusion: The path of generating exercise prescriptions using artificial intelligence, whether via ChatGPT or IHPS, cannot achieve a completely satisfactory state.But can serve as a supplementary tool for professionals issuing exercise prescriptions to patients with hypertension comorbidities, especially in alleviating the financial burden of consulting costs. Future research could further explore the performance of AI in issuing exercise prescriptions, harmonize it with physiological indicators and phased feedback, and develop an interactive user experience.Keywords: artificial intelligence, exercise prescription, hypertension, intelligent health promotion systems, transtheoretical model

The delayed healing of chronic wounds significantly affects patient quality of life, placing a heavy burden on patients, their families, and the healthcare system. Therefore, there is an urgent need to find new treatment methods for chronic wounds. Plant-derived exosome-like nanovesicles (PELNs) may be able to accelerate chronic wound healing. PELNs possess advantages such as good accessibility (due in part to high isolation yields), low immunogenicity, and good stability. Currently, there are limited reports regarding the role of PELNs in chronic wound healing and their associated mechanisms, highlighting their novelty and the necessity for further research. This review aims to provide an overview of PELNs, discussing isolation methods, composition, and their mechanisms of action in chronic wound healing. Finally, we summarize future opportunities and challenges related to the use of PELNs for the treatment of chronic wounds, and offer some new insights and solutions.Keywords: exosomes, exosome-like nanovesicles, plants, chronic wound healing

There is a current research gap regarding the incidence of osteoporosis and its variation by altitude within Sichuan, China. This study aimed to assess the prevalence of osteoporosis among populations residing at different altitudes in western Sichuan Province.Basic Procedures: This study utilized data from a population-based cohort in Sichuan, China. Representative locations were selected, and cluster random sampling was employed to conduct cohort studies across multiple sites in southwestern China. T Baseline data were collected from populations in Mianzhu, Kangting, and Sertar between July 2020 and August 2021. To assess differences in osteoporosis incidence among populations at different altitudes and with varying characteristics, we applied Chi-square and rank-sum tests.Main Findings: The study involved 4074 participants, including 1404 males (34.46%) and 791 individuals diagnosed with osteoporosis (19.42%). The prevalence of osteopenia in mid-altitude and high-altitude regions was 20.05% and 16.28%, respectively, while the prevalence of osteoporosis was significantly different, at 25.85% in mid-altitude areas compared to 13.00% in high-altitude areas (P < 0.001). Further analysis identified statistically significant differences in the prevalence of osteopenia and osteoporosis among females (P< 0.001), middle-aged (P=0.015) and elderly populations (P=0.038), as well as among individuals who were underweight (P=0.011), normal weight (P< 0.001), overweight (P< 0.001), and obese (P=0.038). As altitude increased, the prevalence of osteoporosis decreased in all groups except the elderly, while the prevalence of osteopenia decreased among women and across various BMI categories, but increased among middle-aged and elderly individuals. Additionally, in high-altitude regions, Kangting recorded an 18.10% prevalence of osteopenia and a 14.26% prevalence of osteoporosis, compared to Sertar, which exhibited a 6.54% prevalence of osteopenia and a 6.23% prevalence of osteoporosis, indicating significant differences (P< 0.001).Conclusion: This study demonstrates that higher altitudes are associated with a decreased prevalence of osteopenia and osteoporosis, particularly among females and middle-aged individuals. These results emphasize the importance of developing region-specific osteoporosis prevention strategies.Keywords: osteoporosis, aging, prevalence, altitude, Sichuan province

[Objective] The study aims to compare the genetic diversity and relationship between chloroplast genomes of olive varieties bred in China and those in the mediterranean olives, and to estimate the maternal diversity of olive varieties bred in China, in order to provide a basis for the development of Chinese olive accessions. [Methods] NOVOPlasty v.4.3.1 was used to assemble chloroplast genomes, which were based on the genome re-sequencing data of nine olive varieties bred in China and seven Iranian accessions, both of which were sequenced in this study, as well as fifty-two mediterranean olive accessions downloaded from the database. The sequence polymorphism was calculated. GPA, RAxML-NG, and Network 5.0, and other softwares were used to construct the chloroplast genome map, the relationship of phylogeny, and the network of haplotype, respectively. [Results] The chloroplast genomes of the tested olive accessions were consistent in terms of tetrad structure and number of genes. All chloroplast genomes identified seventeen haplotypes, among which the olive varieties bred in China had only one haplotype which was shared with the most mediterranean cultivated olives. The oleasters had the highest genetic diversity, followed by the mediterranean cultivated olives and then Iranian accessions, while nine olive varieties bred held all genetic diversity of 0. The phylogenetic relationship was consistent with the network of haplotype, and one branch contained most of the mediterranean cultivated varieties, including the Iranian olive accessions and all olive varieties bred in China. [Conclusion] The nine olive varieties bred in China shows an extremely low diversity of maternal origin. It is necessary to select and breed the olive varieties adapted to the habitats in China from a more comprehensive lineage of olive accessions in the later stages.

However, the extremely complex tumor microenvironment (TME) has the characteristics of antioxidant, even if it induces ferroptosis of tumor cells, its killing effect on tumor cells is still very limited. To solve this problem, we constructed a novel nanomaterials (GOx/EC@Fe3O4@CCM). We evaluated the anticancer effect of this nanomaterial in inhibiting tumor growth through comprehensive in vitro and in vivo experiments.Methods: We successfully synthesized GOx/EC@Fe3O4 by one-pan synthesis method, then coated the Hepatocellular carcinoma cell membrane on its surface by co-extrusion technology, and finally synthesized the GOx/EC@Fe3O4@CCM nanoplatforms. We characterized the compounds in terms of morphology, particle size, and Zeta potential. In addition, we also studied the anti-tumor effect of GOx/EC@Fe3O4@CCM nanoplatforms from the following aspects, including the performance test of the nanoplatform, the intracellular effect of the nanoplatform, the anti-tumor effect in vitro, the intracellular ROS analysis, the intracellular effect of EC, and the anti-tumor effect in vivo.Results: The iron-based carriers in GOx/EC@Fe3O4@CCM nanoplatforms are released and produce ferrous ions (Fe2+) in an acidic environment. Due to the limitation of the endogenous level of hydrogen peroxide (H2O2), we introduced GOx into the TME or tumor cells. Under the catalysis of GOx, glucose reacted rapidly to produce a large amount of H2O2, which then combined with Fe2+ to produce a large number of Hydroxyl radical (·OH). Its toxicity leads to dysfunction of cell membrane and organelles, and then causes cell damage. EC inhibits Nuclear factor erythroid 2-related factor 2 (Nrf2) in cancer cells, which effectively down-regulates downstream gene products, including NAD(P)H quinone oxidoreductase 1 (NQO1) and heme oxygenase 1 (HMOX1). A series of chain reactions reduce the escape effect of oxidative stress (OS) and effectively maintain a high level of intracellular oxidation. Furthermore, it induces sustained and intense ferroptosis in tumor cells. Finally, the use of cancer cell membrane modified nanoplatforms due to the homology of membrane protein components improves the tumor cell targeting of the nanoplatforms, showing significant tumor cell inhibition and killing effect in vivo.Conclusion: The results showed that the GOx/EC@Fe3O4@CCM nanoplatforms successfully induced significant ferroptosis of Hepatocellular carcinoma cells through a cascade effect, and finally effectively promoted cancer cell regression.

It is essential to ensure its efficacy and safety by therapeutic drug monitoring (TDM). Quantitative determination of colistin is difficult due to its complex ingredients. Previous determination methods demand intricate sample pre-treatment which are not only time-consuming but also costly, and is difficult to apply in clinical practice. Therefore, in order to carry out quantitative determination of colistin accurately and quickly, we establish a rapid high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) with simple sample pre-treatment process. The sample was purified by acetonitrile to remove the plasma protein. Then purified colistin was effectively separated from terfenadine, an internal standard (IS) using Phenomenex Kinetex C18 column (50.0× 2.1mm, 5μm) with acetonitrile and water mobile phase at a flow rate of 0.5 mL/min and 40°C column temperature. Colistin and IS were monitored in positive ion mode. Our method expressed good linearity in 50.0~6000 ng/mL of colistin B and 28.31~3397.51 ng/mL of colistin A in plasma. Methodology validations, including selectivity, precision, accuracy, recovery, stability, matrix effect, and dilution integrity met acceptance criteria of Bioanalytical Method Validation (M10) of the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH).Keywords: colistin, HPLC-MS/MS, human plasma, protein precipitation, rapid and simple detection

Although the impact of SiNPs on the ecological niche of the lungs has been extensively explored, the role and mechanism of SiNPs in the microenvironment of lung tumors remain elusive.Methods: In this investigation, Lewis lung carcinoma (LLC) was implanted into the left lung in situ after 28 days of intratracheal SiNPs injection into the lungs of mice. This study evaluates the effects of SiNPs on the tumor immune microenvironment both in vitro and in vivo. Our findings indicate that SiNPs can suppress lung cancer by modulating the immune microenvironment of tumors.Results: SiNPs treatment promotes macrophage M1 polarization by activating both NF-κB pathway and glycolytic mechanisms. This phenomenon may be associated with lung inflammation and fluctuation in the pre-metastatic and metastatic microenvironments induced by SiNPs exposure in mice. Additionally, we have shown for the first time that SiNPs have an inhibitory effect on lung carcinogenesis and its progression.Conclusion: This study uniquely demonstrates that SiNPs suppress lung cancer by promoting M1 polarization of macrophages in the immune microenvironment of lung tumors. Our findings are critical in exploring the interaction between SiNPs and lung cancer. Keywords: silicon nanoparticles, lung cancer, macrophage polarization, NF-κB, glycolysis

Abstract In order to investigate the association between the use of cardiomyopeptidin (CMP) and outcomes in critically ill patients with myocardial injury, we conducted a retrospective cohort study in Nanfang hospital, Southern Medical University. Clinical data of patients with myocardial injury were collected retrospectively and adjusted for possible confounders by propensity score weighting. The main outcome was the in-hospital mortality. Secondary outcomes included the major adverse cardiovascular events (MACE) occurring during the hospital, the individual components of MACEs, changes in high sensitive troponin T (hsTnT) levels, length of stay (LOS) in ICU and hospital. A Cox proportional hazards model was constructed to examine the association between the application of CMP and in-hospital mortality. Logistic regression and linear regression are used to analyze secondary outcomes. In total, 339 critically ill patients with myocardial injury were included in the analysis. After inverse probability of treatment weighting (IPTW), the use of CMP was associated with reduced in-hospital mortality (HR: 0.64, 95%CI: 0.43–0.96, P = 0.03). No significant differences were found in change of hsTnT, the occurrence of MACE and LOS in ICU as well as hospital after IPTW. The association was more significant in the subgroup with hsTnT > 3URL (HR: 0.41, 95%CI: 0.23–0.71, P

Ultrasonic metal welding machines are suitable for various complex applications (e.g., battery tabs) through unique mechanical design, special pressure application methods and high-precision welding. This work reports the weldability, forming quality and fractographic analysis of copper multilayered welded joints which were studied by SEM-EDS characterization, micro-hardness testing and tensile testing based on ultrasonic double roller welding (UDRW). Three groups of process parameters (A, B and C) were established to investigate the performance, production quality and welded joint surface interconnections. The tensile testing results of sample under parameter 3 in group A [S-P3(A)] indicate the maximum tensile strength of 69.859 N in T-peel test while the average tensile strength has increased by 58.525 N due to rise in welding time from 2 sec to 5 sec. The results analysis indicates that welding quality features in S-P3(A) joints under 4 bar, 100 mm/s, 45 % have been exploited. The over-welded zone was transformed into good-welded zone. The micro-cracks, fatigue stations and peeling texture in multilayers were reduced. It was found that when the welding energy was 10000 J then the tearing edges and interlayers cracks were minimized while keeping the other parameters constant. Moreover, when the amplitude increased up to 50 %, then numerous micro-cracks and micro-fissure stations were created, which leads to the occurrence of fracture in multi-layer welded joint. The EDS study investigated that the complex features are formed at the interface junction of sample 3 S3(A) in multilayer welds. The complex multilayer microstructures can induce and produce unique hardness properties for battery manufacturing. It leads to high quality and durable welds. Eventually, it is experimentally demonstrated that robust 40 layer welded joints can be obtained by the UDRW process. Data availability: The datasets used and/or analyzed during the current study are available from the corresponding author upon reasonable request.

Objective To review the effect of resection of pediaric craniopharyngioma and the long-term quality of life. Methods The clinical datas before, during and after operation of 30 pediatric craniopharyngioma patients who were operated in Xuanwu Hospital, Capital Medical University from March 2014 to June 2024 were collected for retrospective analysis. The Katz index, body mass index (BMI), as well as one's ability to paparticipate in normal school life and physical exercise at last follow - up were recorded as key factors of long - term quality of life assesement. Results There were 7 (23.33%) of pediatric craniopharyngioma patients were identified as obese, 19 (63.33%) patients had endocrine dysfunction and 30 (100%) were identified as Katz index grade A before operation. Total resection of the tumor was achieved in 29 cases, while one case had subtotal resection. Median follow-up time was 38.00 (17.25, 53.00) months. The number of obese children increased to 9 (30%) during the last follow-up, but showed no statistic significance (χ2 = 0.125, P = 0.727). The number of patients with endocrine dysfunction increased to 27 (90%), and showed statistic significance (χ2 = 4.083, P = 0.039). All 30 cases remained Katz index grade A during the last follow-up. During the last follow-up, only one patient hadn't return to normal school life and 2 patients couldn't join physical exercise in school after total resection of craniopharyngioma. Conclusions Total resection in pediatric craniopharyngioma patients can still achieve good prognosis, and should be the target of surgical treatment.

There are many ships and ports in Shanghai coastal zones, where disastrous weather occurs frequently. Meteorological disasters often threaten the safety of people’s lives and properties along the coast and in the ports. In the past, the meteorological warnings for Shanghai coastal zones are mainly based on those issued for Yangshan Port by Shanghai Marine Meteorological Centre (SMMC), which are called “unified warnings”. However, there are obvious differences in the time and intensity of meteorological disasters in each region, and the unified warnings cannot meet the needs of the production and operation of the shipping and ports. In 2020, Shanghai coastal zones were divided into five sub-zones, where the meteorological forecast and warnings were carried out separately from July 2020. Based on hourly observational data of the representative stations in Shanghai coastal zones and warning signal data from 2016 to 2022, the gale events are selected to analyse the statistical characteristics of temporal and spatial distribution and evaluate the forecast quality and the economic benefits of the zonal warnings. The results show that: (1) The farther away from the coastline, the more gale days, the higher the wind speed and the longer the duration; the higher the wind speed during the process, the more obvious the difference of wind scale. In particular, the wind scale caused by typhoons can range up to 5 levels. (2) Compared with the “unified warning”, the missing alarm rate (MAR) of gale warnings in each sea area has been reduced significantly, by up to 5%, the false alarm rate (FAR) for the western part of Yangtze River estuary is reduced by more than 8% and the TS score is significantly improved by more than 10%. (3) The advance time of gale warnings has been reduced by more than 3 hours, the maintaining duration has been shortened by more than 16 hours at most, which can reduce the loss of nearly 18 million RMB and improve the production efficiency of the coastal zones of Shanghai greatly. The results of this paper show that refined marine meteorological forecasts and early warnings provide a safety guarantee for marine transportation and port production operations, resulting in significant social and economic benefits and the enhancement of the comprehensive guarantee level of marine meteorological services in Shanghai. In the next step, we will continue to research and develop more refined objective forecast methods adapted to this business, then build a regional shared operational system platform and extend it to the Yangtze River Delta region, so as to promote the high-quality development of shipping meteorological integration in the Yangtze River Delta region.

Abstract The ore pass wall in underground mines is often damaged by the impact and wear caused by unloaded ores. Studying the mechanisms of rock damage and failure under different impact angles can provide technical insights for the design and maintenance of the ore passes. This study employed an inclined impact experimental device along with a drop hammer loading test machine to perform cyclic low-energy impact tests on sandstone samples at five different inclined plane angles. The porosity of the rock samples was measured using a nuclear magnetic resonance (NMR) detection system, which provided data on porosity, T2 spectrum distribution, and NMR images of the samples after different numbers of impacts at different slope angles. The results indicate that: (1) Under cyclic inclined plane impact loading, an increase in the inclination angle, leads to reduced damage to the rock sample. The rock sample impacted at a 45° inclined plane exhibited the most severe damage. Rock samples with large inclination angles are more prone to experience rupture fractures at the tip of the inclined plane, primarily due to shear-tensile failure. The porosity changes dramatically at initially slope angles, resulting in greater damage. (2) As the number of impacts increases, the porosity of the samples first decreases, then increases, and subsequently decreases again. This progression corresponds to the closure of large pores following the first impact, followed by the expansion of micropores into macropores after 5 impacts, ultimately leading to gradual degradation of the samples until failure. (3) As the number of impacts increases, new cracks form within the rock sample and small cracks expand. Despite an increase in the number of micropores, the macropores still exert a significant influence on the rock samples, with the macropore spectrum area accounting for over 95%.

Abstract Background Irrational drug use has become a global problem threatening human health. As future health professionals, medical college students’ medication literacy (ML) is critical. Their mastery of medication-related knowledge will directly affect public medication safety in the future. Methods The initial scale was developed through a literature review and was modified through expert consultation and student interviews to form the initial scale with 14 items. In 2020, a questionnaire survey was conducted among students in a medical college for item analysis, reliability test, validity test and other analyses. Results The total Cronbach’s α coefficient was 0.826 and split-half reliability was 0.852. The Cronbach’s α coefficients for functional medication literacy, communicative medication literacy, and critical medication literacy were 0.901, 0.858, and 0.851, respectively. The item-level content validity index (I-CVI) ranged from 0.833 to 1.000 (≥ 0.78). Factor analysis of 14 items showed that KMO = 0. 852(> 0.7) and Bartlett’s spherical test p 40%). The confirmatory factor analysis identified a three-factor model and showed goodness of fit indices for the scale: The χ²/df = 2.623, The Goodness of Fit Index (GFI) = 0.905, The Comparative Fit Index (CFI) = 0.950, Normed Fit Index (NFI) = 0.922, Tucker-Lewis index (TLI) = 0.938, and The Root Mean Square Error of Approximation (RMSEA) = 0.078. Conclusion A new scale for evaluating the medication literacy of Chinese medical college students was preliminarily developed, demonstrating good reliability and validity. Itcan be used as a preliminary measurement tool for assessing medical students’ medication literacy. However, due to the limitations of this study, the practical application of the scale needs to be further examined in a larger sample and should be refined in future studies.

In order to enhance the drug anti-tumor efficacy and biocompatibility，diselenide-hyaluronic acid has been developed as tumor therapy drug under irradiation in this research. In cellular toxicity evaluation，we observed that the introduction of hyaluronic acid had reduced the toxicity of diselenide agent. Under low therapeutic irradiation dose 4 Gy，remarkable anti-tumor effect has been realized，which tumor cellular viability can be realized with the drug concentration of only 27 μg/mL. The diselenide-hyaluronic acid developed in this research can provide an effective tumor therapy protocol under irradiation.

The pre-analytical phase is particularly error-prone, contributing to around 70% of laboratory errors. High specimen rejection rates can delay diagnosis and treatment, cause patient discomfort, and increase healthcare costs. Quality Control Circles (QCC) have been introduced to medical institutions to improve process efficiency and reduce errors. This study aims to evaluate the effectiveness of QCC practices in reducing specimen rejection rates in a hospital clinical laboratory.Methods: A QCC initiative was implemented in the clinical laboratory from July 2021 to August 2022. The QCC comprised members from the clinical laboratory, nursing department, and administration. The initiative followed the PDCA (Plan-Do-Check-Act) cycle and involved multiple quality control methods, including flowchart analysis, Pareto analysis, and Fishbone diagrams. The effectiveness of the initiative was evaluated using statistical analyses of specimen rejection rates before and after implementation.Results: The QCC initiative led to a significant reduction in specimen rejection rates. The monthly specimen rejection rate decreased from an average of 1.13% before the intervention to 0.27% after the intervention. The most significant factors contributing to specimen rejection were identified as lack of sample collection information and blood clotting. Targeted interventions, such as appointing specimen collection liaisons, establishing a quality control team, and providing training on blood collection procedures, were implemented. These measures resulted in a notable decrease in the proportion of rejected specimens due to the identified factors.Conclusion: The implementation of QCC practices effectively reduced specimen rejection rates in the hospital laboratory. The study highlights the importance of systematic quality control methods and targeted interventions in improving laboratory processes. The success of the QCC initiative demonstrates its potential for broader application in other healthcare settings to enhance quality and efficiency.Keywords: quality control circle, specimen rejection, quality improvement, PDCA cycle, Pareto analysis

The guardians, who are primarily responsible for the daily care of children, play a crucial role in the early detection of this condition. Therefore, this study aims to explore knowledge, attitude, and practices (KAP) toward CP among guardians of young boys; results would provide a theoretical basis for the development of health education programs.Methods: This web-based cross-sectional study was conducted among guardians of boys in the Department of Pediatric Surgery, local hospital between June 2023 and September 2023. A self-designed questionnaire was developed to collect demographic information of the guardians and to assess their knowledge, attitudes and practices toward CP.Results: A total of 394 questionnaires were collected. Among the guardians, 143 (36.29%) of them were male, 375 (95.18%) were the parents of the children, 279 (70.81%) had a junior college or bachelor’s degree, and 46 (11.68%) reported their children had CP. The knowledge, attitudes and practices scores were 4.00± 2.00 (possible range: 0– 7), 35.63± 3.40 (possible range: 9– 45), and 23.03± 6.97 (possible range: 9– 45), respectively. The structural equation model demonstrated that knowledge had direct effects on attitudes (β=0.63, p< 0.001), and practices (β=0.81, p< 0.001). Moreover, attitudes had direct effects on practices (β=0.43, p< 0.001).Conclusion: This study found insufficient knowledge, positive attitudes, but poor practices toward the CP in guardians of boys, especially among participants from rural areas of families with lower income. It is recommended to tailor educational initiatives and implement strategies to bridge the knowledge-practice gap toward concealed penis in boys.Keywords: knowledge. attitudes, practices, concealed penis, cross-sectional study

To clarify the causal relationship, we conducted a Mendelian randomization (MR) analysis using data from genome-wide association studies (GWAS).Subjects and Methods: The GWAS dataset of vitamin D (GWAS ID: ukb-d-30890_irnt; sample size: 329247) was obtained from the IEU Open GWAS project. And that of TMDs (GWAS ID: finn-b-TEMPORO; sample size: 134280), initiated on August 25th, 2017 and publicly released on December 18th, 2023, was extracted from the FinnGen dataset, whose cases were diagnosed based on the revised International Classification of Diseases, 10th Edition (ICD-10) code K07.6. Both datasets were obtained from the European population. According to three assumptions of MR analysis, a bi-directional MR analysis was performed to measure the causal relationship, with Inverse variance weighted (IVW) as the primary method and MR Egger and Weighted median as supplement. Moreover, diverse sensitivity analyses, including Cochran’s Q test, MR Egger intercept, Mendelian randomized polymorphism RESidual Sum and Outlier (MR-PRESSO), and leave-one-out analysis, were used to verify the stability of the findings.Results: The MR analysis supported causal effects of vitamin D levels on TMDs risks within the European population using IVW method [odds ratio = 1.316; 95% confidence interval = 1.086 to 1.595; P = 0.005], supported by MR Egger and Weighted median. While there was no indication that TMDs have a direct impact on vitamin D levels [β: − 0.00738, standard error = 0.00665; P = 0.568].Conclusion: The study revealed that within the European population higher levels of vitamin D led to higher risks of developing temporomandibular disorders, but found no obvious evidence that TMDs are causally associated with vitamin D. The conclusion should be cautiously interpreted, given the selection bias of TMDs patients sample.Keywords: Mendelian randomization analysis, temporomandibular joint disorders, vitamin D, 25-hydroxyvitamin D

Abstract Background Disorders of consciousness (DoC) are a group of conditions that affect the level of awareness and communication in patients. While neuroimaging techniques can provide useful information about the brain structure and function in these patients, most existing methods rely on a single modality for analysis and rarely account for brain injury. To address these limitations, we propose a novel method that integrates two neuroimaging modalities, functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI), to enhance the classification of subjects into different states of consciousness. Method and results The main contributions of our work are threefold: first, after constructing a dual-model individual graph using functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI), we introduce a brain injury mask mechanism that consolidates damaged brain regions into a single graph node, enhancing the modeling of brain injuries and reducing deformation effects. Second, to address over-smoothing, we construct a dual-level graph that dynamically construct a population-level graph with node features from individual graphs, to promote the clustering of similar subjects while distinguishing dissimilar ones. Finally, we employ a subgraph exploration model with task-fMRI data to validate the interpretability of our model, confirming that the selected brain regions are task-relevant in cognition. Our experimental results on data from 89 healthy participants and 204 patients with DoC from Huashan Hospital, Fudan University, demonstrate that our method achieves high accuracy in classifying patients into unresponsive wakefulness syndrome (UWS), minimally conscious state (MCS), or normal conscious state, outperforming current state-of-the-art methods. The explainability results of our method identified a subset of brain regions that are important for consciousness, such as the default mode network, the salience network, the dorsal attention network, and the visual network. Our method also revealed the relationship between brain networks and language processing in consciousness, and showed that language-related subgraphs can distinguish MCS from UWS patients. Conclusion We proposed a novel graph learning method for classifying DoC based on fMRI and DTI data, introducing a brain injury mask mechanism to effectively handle damaged brains. The classification results demonstrate the effectiveness of our method in distinguishing subjects across different states of consciousness, while the explainability results identify key brain regions relevant to this classification. Our study provides new evidence for the role of brain networks and language processing in consciousness, with potential implications for improving the diagnosis and prognosis of patients with DoC.

This study aimed to investigate the specific challenges related to access, quality, and coordination of rehabilitation and long-term care experienced by older adult stroke survivors and their caregivers within the Chinese community.Methods: A qualitative phenomenological design was employed to explore the lived experiences of stroke survivors and their caregivers within the Chinese community. A purposive sampling method was used to recruit participants from June to August 2023. Participants engaged in face-to-face semi-structured interviews. The data were analyzed using an inductive thematic analysis approach to identify and understand key themes and sub-themes.Results: The study involved 38 participants, consisting of 21 older adult stroke survivors (13 males, 8 females) and 17 family caregivers (7 males, 10 females), recruited from five Chinese community health service stations. The analysis identified four distinct themes and 11 sub-themes that encapsulated the challenges faced by participants. These themes include (1) Difficulties in accessing medical services (insufficient medical resources, lack of rehabilitation resources, and time-consuming processes), (2) Challenges in daily life (inconvenience in daily mobility, inadequate financial support, and difficulties in applying for home care services), (3) Psychosocial stress (loneliness, powerlessness, and worry about burdening others), (4) Insufficient information (lack of awareness of available community services, and limited public health education activities).Conclusion: Older adult stroke survivors and their caregivers in Chinese communities face significant challenges. To improve their well-being and quality of life, it is crucial to address these challenges through enhanced access to healthcare, better support for daily living, and more effective information dissemination. Meeting these needs requires a coordinated effort from healthcare providers, community stakeholders, and policymakers to develop and implement effective, long-term care solutions.Keywords: stroke, survivors, caregivers, community, qualitative research

The proliferation and differentiation of muscle satellite cells and the apoptosis of cervical myocytes play important roles in the repair of chronic cervical muscle injuries; therefore, this study aimed to explore the potential mechanisms of Tuina to promote the repair of cervical muscle injuries in terms of the proliferation and differentiation of satellite cells and the apoptosis of myocytes.Patients and Methods: Twenty-eight Wistar rats were randomly divided into control group, model group, Tuina group, and meloxicam group, with 7 rats in each group. Except for the control group, each group were establish a chronic cervical muscle injury model (CCMI). Meloxicam (0.79 mg/kg) was administered by gavage, and in the Tuina group, pressure was applied to the Fengchi acupoint on the affected side once a day. Morphological changes of cervical muscle tissues were detected by ultrasonic diagnostic instrument and HE staining, electrophysiological recordings of electromyographic changes, apoptosis rate was detected by TUNEL staining, and positive expression of Bax, Bcl-2, IGF-1, MyoD, and Pax-7 were detected by Immunohistochemistry and Western blot.Results: In CCMI model rats, we observed that the cervical muscle fibers were disorganized, with irregular morphology, and the amplitude of electromyography was significantly weakened, while Tuina could significantly improve these symptoms and effectively promote the repair of chronic cervical muscle injury. Meanwhile, compared with the model group, Tuina could significantly increase the expression levels of IGF-1 (P< 0.01) and MyoD (P< 0.05) and decrease the expression level of Pax7 (P< 0.05). In addition, we found that the number of apoptotic cells in cervical myocytes was reduced after Tuina intervention (P< 0.05), and Tuina inhibited the expression of pro-apoptotic factor Bax (P< 0.01) and promoted the expression of anti-apoptotic factor Bcl-2 (P< 0.05).Conclusion: Tuina can promote the proliferation and differentiation of satellite cells to repair chronic cervical muscle injury by regulating the expression of Pax7, MyoD, and IGF-1, as well as inhibiting the expression of Bax and promoting the expression of Bcl-2 to ameliorate the apoptosis of cervical myocytes in CCMI model rats.Keywords: Tuina, cervical spondylosis, neck pain, satellite cell

Disseminated Intravascular Coagulopathy (DIC) represents a critical complication of sepsis, contributing to increased mortality and economic burden. Despite various prognostic scoring systems, there is a lack of a specific model for DIC prediction in sepsis patients.Methods: This observational study included 336 sepsis patients. Clinical and laboratory data were collected, and prognoses were defined according to established criteria.Results: We enrolled 336 patients, with 304 in the non-DIC group and 32 in the DIC group. Patients with DIC had notably lower platelet (PLT) and higher levels of prothrombin time (PT), lactate (LAC), and procalcitonin (PCT) compared to those without DIC. Univariate and multivariate analyses identified risk factors associated with the DIC, showing that PLT (OR = 0.985, 95% CI 0.978– 0.993, p < 0.001), PT level (OR = 1.140, 95% CI 1.004– 1.295, p = 0.044), and LAC (OR = 1.101, 95% CI 0.989– 1.226, p = 0.078) were related factors. A risk model was established, and its sensitivity and specificity in predicting DIC among sepsis patients were assessed by comparing it to the SOFA score. The area under the ROC curve for the model was 0.850, while the SOFA score was 0.813. With a model score >− 2.12, the sensitivity for predicting DIC was 84.4%, and the specificity was 75.0%.Conclusion: Our study introduces a predictive model for DIC detection in sepsis patients, emphasizing the need for clinicians to focus on patients with high model scores for timely intervention.Keywords: sepsis, risk model, disseminated intravascular coagulopathy, platelet, mortality

In China, higher education increasingly emphasizes innovation and entrepreneurship, recognizing its pivotal role in enhancing college students’ entrepreneurial skills. While extensive research exists on entrepreneurship education for undergraduate students in Chinese universities and vocational colleges, there is a notable gap in studies specifically addressing entrepreneurship coaching for vocational art and design students. This investigation addresses this gap by examining the development of entrepreneurship coaching indicators for vocational art and design majors through a comprehensive literature review. By employing the fuzzy Delphi method, a questionnaire survey involving 12 experts was conducted to establish entrepreneurship coaching indicators for vocational art and design majors in Guangdong, China. The findings reveal a framework comprising entrepreneurship knowledge, practical skills, entrepreneurial dispositions, and intentions, organized into 4 dimensions, 15 principal indicators, and 46 sub-indicators.

In this article, we work on vector optimization problems in linear topological spaces. Our vector optimization problems have weakened convex inequality constraints and weakened affine equality constraints. Our inequalities are given by partial orders that are induced by pointed convex cones. We prove a Farkas–Minkowski-type theorem of alternative and obtain some optimality conditions through the discussions of vector saddle points and scalar saddle points.

Objective Given the high operating speeds, minimal residual acceleration margin, and open-air track conditions of EMU (electric multiple units), as well as the deficiencies in conventional combination correction methods such as poor accuracy in criterion extraction and significant torque adjustment losses. It is aimed to optimize EMU adhesion utilization by analyzing and improving speed acquisition, fault identification, criterion extraction, and torque adjustment. Method A segmented T-method and median filtering method for speed acquisition is employed, and faulty speed data is identified and substituted to reduce the impact of speed interference/faults on adhesion control. The acceleration difference impact rate is used instead of impact rate and the differentiator is substituted with a high-pass filter to minimize the impact of complex track surface conditions on adhesion criterion extraction. For torque adjustment, it latches the torque at the previous wheel slip/skid trigger moment and uses this as a reference to calculate the reducing and increasing torque step sizes in real-time. The reducing and increasing step sizes are divided into 10 segments, executed from large to small to minimize torque losses. The feasibility of these methods is verified through experiments using a type of EMU as example. Result & Conclusion Experimental results demonstrate that during the entire acceleration and deceleration process of anti-slip and anti-skid tests, the deviation of the axle speed from the reference speed is limited. Torque adjustments do not exhibit significant repeated fluctuations, resulting in relatively less train impact. The traction and braking test data calculation analysis show that the adhesion utilization rates of traction anti-slip and braking anti-skid are both greater than 90%, effectively improving adhesion utilization.
