Until recently, the functions of border-associated macrophages have been poorly understood and largely overlooked. However, a recent study reported that border-associated macrophages participate in stroke-induced inflammation, although many details and the underlying mechanisms remain unclear. In this study, we performed a comprehensive single-cell analysis of mouse border-associated macrophages using sequencing data obtained from the Gene Expression Omnibus(GEO) database(GSE174574 and GSE225948). Differentially expressed genes were identified, and enrichment analysis was performed to identify the transcription profile of border-associated macrophages. CellChat analysis was conducted to determine the cell communication network of border-associated macrophages. Transcription factors were predicted using the ‘pySCENIC' tool. We found that, in response to hypoxia, borderassociated macrophages underwent dynamic transcriptional changes and participated in the regulation of inflammatory-related pathways. Notably, the tumor necrosis factor pathway was activated by border-associated macrophages following ischemic stroke. The pySCENIC analysis indicated that the activity of signal transducer and activator of transcription 3(Stat3) was obviously upregulated in stroke, suggesting that Stat3 inhibition may be a promising strategy for treating border-associated macrophages-induced neuroinflammation. Finally, we constructed an animal model to investigate the effects of border-associated macrophages depletion following a stroke. Treatment with liposomes containing clodronate significantly reduced infarct volume in the animals and improved neurological scores compared with untreated animals. Taken together, our results demonstrate comprehensive changes in border-associated macrophages following a stroke, providing a theoretical basis for targeting border-associated macrophages-induced neuroinflammation in stroke treatment.展开更多

文摘Background:The trajectory of intrinsic capacity(IC)among the older population is characterized by its diversity and is predictive of adverse health outcomes such as disability,nursing home admission,decline in quality of life,and mortality.Gaining an understanding of the trajectory of IC and the factors that influence it is of paramount importance for fostering healthy aging.This research is focused on exploring the trajectory of IC among older adults in China and examining the factors that influence it.Methods:This observational longitudinal cohort study leveraged data from the China Health and Retirement Longitudinal Study(CHARLS),which was conducted in the years 2011,2013,and 2015.For the purpose of this analysis,a total of 2,233 participants who were aged 60 and over were included.A Growth Mixture Model(GMM)was utilized to define trajectory categories for IC.Influential factors were ascertained based on the health ecology model,and binary logistic regression analysis was utilized to investigate the factors linked with the different trajectory categories.Results:Two distinct trajectory classes of IC were identified:Class 1,the normal-stable group,encompassed 90.4%of the elderly population,while Class 2,the declining group,made up 9.6%.Advanced age and a history of stroke were found to be significantly associated with Class 2.High scores in activities of daily living(ADL),employment status,receiving primary or junior high school education,and residence in the East or Central regions of China were significantly linked with Class 1.Conclusion:The trajectory of IC among older Chinese adults is marked by its heterogeneity.Advanced age and a history of stroke are significant risk factors for a declining IC trajectory,while higher ADL scores,being employed,receiving primary or junior high school education,and residing in the East or Central regions of China are protective factors associated with a stable IC trajectory.Healthcare institutions must closely monitor IC levels and understand these trajectory patterns to implement personalized and targeted interventions promptly to maintain IC at a healthy level and advocate for healthy aging.

文摘BACKGROUND Aseptic loosening remains the leading cause of revision in primary total hip arthroplasty(pTHA).However,the literature demonstrates significant variability regarding the relative contributions of different factors.AIM To investigate the key determinants of aseptic loosening,we performed a systematic review and meta-analysis.METHODS A comprehensive search of PubMed,Web of Science,EMBASE,and the Cochrane Library was conducted,encompassing studies from database inception to January 1,2025.Meta-analyses were performed to evaluate factors associated with aseptic loosening following pTHA.Inclusion and exclusion criteria were systematically applied at each stage to ensure methodological transparency and reproducibility.Study quality was assessed using standardized categories.Pooled odds ratio(OR)with corresponding 95%confidence interval were calculated with random-or fixed-effects models to generate reliability estimates,and study heterogeneity was visualized using forest plots.Ten factors,categorized into patient-,surgeon-,and device-related domains,were reviewed and meta-analyzed.Funnel plot analysis demonstrated a relatively symmetrical distribution,suggesting minimal publication bias.RESULTS A meta-analysis of 20 studies(520789 participants)found a pooled prevalence of 1.96%.Significant risk factors for aseptic loosening after pTHA included elevated body mass index(OR=1.116,P<0.001),higher Charlson comorbidity index(OR=1.378,P<0.001),prosthesis-related factors(OR=1.497,P<0.001),and adverse lifestyles(OR=2.198,P=0.037).Protective factors were non-white race(OR=0.445,P<0.001)and favorable genetics(OR=0.723,P<0.001).Male sex increased risk(OR=1.232,P=0.016),while age and anatomy were not significant.Surgical expertise showed a slight protective effect(OR=1.048,P<0.001).A comprehensive understanding of the modifiable and non-modifiable factors contributing to aseptic loosening after pTHA requires consideration of patient-related factors,surgical expertise,and prosthesis characteristics.CONCLUSION The identification of these factors is critical for risk mitigation.High-risk patients should receive targeted counseling regarding individualized profiles.Further studies are warranted to establish clearer causal relationships and identify additional contributing factors.
文摘BACKGROUND Esophageal cancer is highly malignant and frequently metastasizes to bones.Concomitant depression worsens prognosis;however,its incidence and determinants in this specific population remain poorly defined.AIM To determine the incidence of depression and its independent risk factors in patients with esophageal cancer and bone metastasis.METHODS A total of 100 consecutive eligible patients admitted between March 2022 and March 2025 were recruited.Depression was assessed with the Beck Depression Inventory-II;scores>4 defined the depression group(n=42)and scores≤4 the non-depression group(n=58).Demographic,clinical,and laboratory variables were compared between the groups.Multivariate logistic regression was used to identify independent risk factors.RESULTS Depression prevalence was 42.0%(42/100).Univariate analysis demonstrated significant differences in monthly per-capita household income,education level,social support,sleep disorders,and serum high-sensitivity C-reactive protein(all P<0.05);no differences were observed in sex,age,tumor characteristics,or other laboratory indices(all P>0.05).Multivariable analysis revealed the following independent risk factors for depression:Low income[odds ratio(OR)=2.66,95%confidence interval(CI):1.17-6.03],low education(OR=2.46,95%CI:1.08-5.61),low social support(OR=5.10,95%CI:1.81-14.39),sleep disorders(OR=2.79,95%CI:1.23-6.35),and elevated high-sensitivity C-reactive protein(OR=1.31 per unit increase,95%CI:1.18-1.46).CONCLUSION Depression is common among patients with esophageal cancer and bone metastasis.Low socioeconomic status,limited education,insufficient social support,sleep disturbances,and systemic inflammation were independent predictors.Interventions that address these modifiable factors may reduce depression risk in this population.

文摘Objective The basic helix-loop-helix(bHLH)transcription factors(TFs)are pivotal in regulating fungal growth,development,and secondary metabolism.However,the knowledge about the Ganoderma lucidum bHLHs(GlbHLHs)in ganoderic acid(GA)biosynthesis of G.lucidum was limited.This study aimed to explore the functions of bHLH genes in ganoderic acid biosynthesis during G.lucidum growth development.Methods First,the genome-wide identification of GlbHLHs was performed through Hidden Markov model searches and Two-way blast.Furthermore,through physicochemical properties,gene structure,and phylogenetic analysis,as well as combining the transcriptome and metabolome data from different developmental stages of G.lucidum,candidate GlbHLHs were screened.Subsequently,their regulatory roles in ganoderic acid biosynthesis were explored using yeast one-hybrid and dual-luciferase reporter assays.Results A total of 11 GlbHLH members were characterized in G.lucidum.The upstream promoter regions of these genes enriched hormones and abiotic stress responsive elements.Although individual ganoderic acid monomers demonstrated marked differences in accumulation patterns across specific growth phases and tissue types,overall,the total GA content was consistently higher in caps than in stipes throughout development.In addition,all GlbHLHs exhibited high expression in whole G.lucidum from the primordium to maturation stages.Among them,GlbHLH5 and GlbHLH7 showed the highest expression in any stage and highly correlated with key genes associated with GA pathway.Functional validation through dual-luciferase assays and yeast one-hybrid experiments had demonstrated that GlbHLH5 activated the P2 region of the lanosterol synthase promoter,while GlbHLH7 activated the promoters of squalene epoxidase and squalene synthase.Conclusion Compared to plants,G.lucidum harbored a small number of bHLH members but all high expression in any stages.Additionally,GlbHLH5 and GlbHLH7 with the highest expression among GlbHLHs showed activation in regulating the biosynthesis of GA.These results provide a theoretical reference for further research on ganoderic acid regulation in G.lucidum,and thereby providing a molecular foundation for enhancing ganoderic acid yield to optimize the medicinal value of G.lucidum.

文摘The endpoint carbon content in the converter is critical for the quality of steel products,and accurately predicting this parameter is an effective way to reduce alloy consumption and improve smelting efficiency.However,most scholars currently focus on modifying methods to enhance model accuracy,while overlooking the extent to which input parameters influence accuracy.To address this issue,in this study,a prediction model for the endpoint carbon content in the converter was developed using factor analysis(FA)and support vector machine(SVM)optimized by improved particle swarm optimization(IPSO).Analysis of the factors influencing the endpoint carbon content during the converter smelting process led to the identification of 21 input parameters.Subsequently,FA was used to reduce the dimensionality of the data and applied to the prediction model.The results demonstrate that the performance of the FA-IPSO-SVM model surpasses several existing methods,such as twin support vector regression and support vector machine.The model achieves hit rates of 89.59%,96.21%,and 98.74%within error ranges of±0.01%,±0.015%,and±0.02%,respectively.Finally,based on the prediction results obtained by sequentially removing input parameters,the parameters were classified into high influence(5%-7%),medium influence(2%-5%),and low influence(0-2%)categories according to their varying degrees of impact on prediction accuracy.This classi-fication provides a reference for selecting input parameters in future prediction models for endpoint carbon content.

文摘BACKGROUND Dental implants are widely used to replace missing teeth.Currently,clinicians assess osseointegration success by measuring the implant’s stability within the bone and monitoring the marginal tissue height.Diabetes,especially type 2 diabetes mellitus(T2DM),has been reported to impair implant healing,drastically reducing implant success rates.AIM To analyze the high-risk factors for inflammatory response and prognosis after dental implantation in patients with T2DM,and provide strong evidence for reducing the incidence of postimplant peri-implantitis(PI).METHODS We performed a retrospective review of 146 patients with T2DM who had dental implants placed at Tianjin Fifth Central Hospital,between September 2021 and September 2023,which was regarded as the observation group.Moreover,60 ageand gender-matched individuals with normal blood glucose levels served as the control group.The general information,postoperative periodontal indices,and levels of inflammatory factors were comprehensively analyzed and compared.Furthermore,the incidence of postimplant PI was counted,and multivariate logistic regression was used to identify the determinants of postimplant PI.RESULTS In terms of the periodontal indices,the probing depth,modified sulcus bleeding index,and marginal bone loss in the observation cohorts began to increase significantly at 6 months and 3 months,respectively,after the completion of dental implant restoration.The T2DM cases demonstrated significantly elevated counts of leukocytes,lymphocytes,and neutrophils compared to the controls at 24 hours postoperatively.Moreover,the TNF-α,IL-1β,and IL-6 concentrations started to increase significantly in the gingival crevicular fluid 3 months after the completion of dental implant restoration in both cohorts,with the observation group exhibiting higher levels than the controls at each time point.63 out of the 146 cases developed PI.Multivariate logistic regression analysis indicated that high glycosylated hemoglobin levels,smoking,daily tooth-brushing frequency of less than once,and the anterior tooth as the implant site independently contributed to postimplant PI in T2DM cases,while a tooth-brushing duration of≥3 minutes was a protective factor.CONCLUSION Patients with T2DM are at risk of developing PI following dental implantation.Clinically,it is necessary to enhance the identification of risk factors for postimplant PI,improve risk prediction,prevention,and control,and formulate targeted intervention countermeasures to reduce the occurrence of postimplant PI.
文摘BACKGROUND Cardiovascular(CV)complications are common in intensive care unit(ICU)patients after gastrointestinal surgery and are associated with increased mortality and prolonged hospital stay.The optimization of postoperative nursing interventions,particularly pain management,is crucial for reducing such complications.AIM To investigate the effects of enhanced recovery nursing on CV complications after gastrointestinal surgery in ICU patients and associated risk factors.METHODS A retrospective analysis was conducted on 78 adult patients who underwent gastrointestinal surgery in the ICU of our hospital between February 2023 and September 2024.Among them,40 patients received standard care(control group),while 38 received enhanced recovery nursing(observation group).We compared the incidence of CV complications and nursing satisfaction between the two groups.Patients were divided into CV complication and non-complication groups based on complication occurrence,and logistic regression analysis was used to identify risk factors.RESULTS In the control and observation groups,the incidence of CV complications was 30.0%(12/40)and 18.4%(7/38),with a nursing satisfaction rate of 70.0%(28/40)and 92.1%(35/38),respectively.The postoperative pain score at 14 days was significantly lower in the observation group(0.27±0.15)compared to the control group(1.65±0.37),with all differences being statistically significant(P<0.05).Univariate analysis indicated significant differences in age,body mass index,hypertension,diabetes,smoking history,history of heart failure,and previous myocardial infarction(P<0.05).Multivariate logistic regression identified heart failure history,previous myocardial infarction,age,hypertension,and diabetes as independent risk factors,with odds ratios of 1.195,1.528,1.062,1.836,and 1.942,respectively(all P<0.05).CONCLUSION Implementing enhanced recovery nursing for ICU patients after gastrointestinal surgery is beneficial in reducing the incidence of CV complications and improving nursing satisfaction.

文摘BACKGROUND Bile leakage is a common complication following laparoscopic common bile duct exploration(LCBDE)with primary duct closure(PDC).Identifying and analyzing the risk factors associated with bile leakage is crucial for improving surgical outcomes.AIM To explore the value analysis of common risk factors for bile leakage after LCBDE and PDC,with a focus on strict adherence to indications.METHODS Clinical data of 106 cases undergoing LCBDE+PDC in the Hepatobiliary and Pancreatic Surgery Department(Division 1)of Chuzhou First People’s Hospital from April 2019 to March 2024 were collected.Retrospective and multiple factor regression analysis were conducted on common risk factors for bile leakage.The change in surgical time was analyzed using the cumulative summation(CUSUM)method,and the minimum number of cases required to complete the learning curve for PDC was obtained based on the proposed fitting curve by identifying the CUSUM maximum value.RESULTS Multifactor logistic regression analysis showed that fibrinous inflammation and direct bilirubin/indirect bilirubin were significant independent high-risk factors for postoperative bile leakage(P<0.05).The time to drain removal and length of hospital stay in cases without bile leakage were significantly shorter than in cases with bile leakage(P<0.05),with statistical significance.The CUSUM method indicated that a minimum of 51 cases were required for the surgeon to complete the learning curve(P=0.023).CONCLUSION With a good assessment of duodenal papilla sphincter function,unobstructed bile-pancreatic duct convergence,exact stone clearance,and sufficient surgical experience to complete the learning curve,PDC remains the preferred method for bile duct closure and is worthy of clinical promotion.
文摘BACKGROUND The development of prostate cancer(PC)frequently intensifies negative emotional states,such as anxiety and depression,which compromise the effectiveness of radical surgery and reduce treatment adherence.In this study,we hypothesized that psychological resilience plays a crucial role in this process and explored its impact.AIM To investigate the association of resilience with anxiety and depression in patients with PC and to analyze the influencing factors.METHODS We selected 147 patients with PC who visited Qingdao Traditional Chinese Medicine Hospital from January 2022 to June 2024.The resilience scores of patients with PC were assessed using the Connor-Davidson Resilience Scale(CDRISC)from the tenacity,self-improvement,and optimism dimensions.Based on the total CD-RISC score,patients were categorized into groups A(total CD-RISC score>63 points,n=69)and B(total CD-RISC score≤63 points,n=78)for comparative analysis of anxiety[Hamilton Anxiety Rating Scale(HAMA)],depression[Hamilton Depression Rating Scale(HAMD)],sexual function[International Index of Erectile Function-5(IIEF-5)and Sexual Life Quality Questionnaire-Quality of Life(SLQQ-QOL)],and quality of life[the EORTC Core Quality of Life Question naire(QLQ-C30)].The association between CD-RISC and the above indicators was analyzed with Spearman correlation coefficients,and the influencing factors of resilience in patients with PC were identified with binary logistic regression.RESULTS Group A demonstrated statistically lower HAMA and HAMD scores and markedly higher scores of IIEF-5,SLQQQOL,and various QLQ-C30 aspects.Correlation analysis revealed that CD-RISC was significantly negatively correlated with HAMA and HAMD scores and significantly positively correlated with IIEF-5,SLQQ-QOL,and QLQ-C30 total scores.Binary logistic regression analysis revealed educational and per capita monthly household income levels as significant influencing factors of resilience in patients with PC.CONCLUSION Our results indicate a significant correlation of resilience with anxiety and depression in patients with PC.The milder the anxiety and depression emotions in patients,the higher their resilience.Further,assisting patients with PC to improve their educational and per capita monthly household income levels will help their resilience to some extent.
文摘Working at height is widespread across various industries,with frequent and hazardous falls occurring regularly.Such tasks are often linked to multifactorial issues,where the interplay of diverse factors leads to accidents that are challenging to control effectively.This study establishes an index system for the factors influencing falls from height by statistically analyzing 101 incidents,identifying 64 causative elements classified into four categories.These include 17 factors related to operator condition and behavior,13 concerning equipment and facility conditions,7 pertaining to site conditions,and 27 associated with production operations management.Utilizing the Apriori algorithm and Gephi software,the study mined the association rules of causal factors in falls from height and constructed their network diagram.By examining association rules with high support,confidence,and lift,the relationships between key causal factors leading to accidents are clarified,identifying critical operational control points and providing a scientific foundation for reducing the incidence of falls from height.Currently,China's standards related to working at height remain fragmented.This study lays the foundation for the development of comprehensive,systematic,generic safety management standards for working at height,satisfying the needs of the field.

文摘A non-negative latent factor(NLF)model is able to be built efficiently via a single latent factor-dependent,non-negative and multiplicative update(SLF-NMU)algorithm for performing precise representation to high-dimensional and incomplete(HDI)matrix from many kinds of big-data-related applications.However,an SLF-NMU algorithm updates a latent factor relying on the current update increment only without considering past learning information,making a resultant model suffer from slow convergence.To address this issue,this study proposes a proportional integral(PI)controller-enhanced NLF(PI-NLF)model with two-fold ideas:1)Designing an increment refinement(IR)mechanism,which formulates the current and past update increments as the proportional and integral terms of a PI controller,thereby assimilating the past update information into the learning scheme smoothly with high efficiency;2)Deriving an IR-based SLF-NMU(ISN)algorithm,which updates a latent factor following the principle of an IR mechanism,thus significantly accelerating an NLF model's convergence rate.The simulation results on eight HDI matrices collected by real applications validate that a PI-NLF model outstrips several leading-edge models in both computational efficiency and accuracy when estimating missing data within an HDI matrix.The proposed PI-NLF model can be effectively applied to applications involving HDI matrix like e-commerce system,social network,and cloud service system.The code is available at https://github.com/yuanyeswu/PINLF/blob/mainIPINLF-code.zip.
文摘BACKGROUND Pain often predisposes patients with diabetic foot ulcers(DFUs)to negative emotional states,such as anxiety and depression,which can significantly impair treatment outcomes and recovery.However,very few studies have explored the relationship between anxiety,depression,and pain in DFUs,as well as the associated risk factors.AIM To analyze the correlation between anxiety,depression,and pain in patients with DFUs and to identify the associated risk factors.METHODS This study included 106 patients diagnosed with DFUs who were admitted to Tiantai County People’s Hospital between March 2022 and March 2024.The patients’anxiety levels were evaluated using Zung’s self-rating anxiety scale(SAS),depression status was assessed using Zung’s self-rating depression scale(SDS),and pain intensity was assessed using the visual analog scale(VAS).Subsequently,correlations between SAS,SDS,and VAS scores were analyzed.Univariate and multivariate analyses were conducted to explore the risk factors that contributed to anxiety and depression in patients with DFUs.RESULTS Among the 106 patients,39.62%exhibited anxiety and 43.40%presented with depression.Most patients experiencing anxiety or depression exhibited mild symptoms,with no severe cases observed.Compared with asymptomatic patients,those with anxiety or depression had significantly higher VAS scores.Correlation analysis indicated a significant positive relationship between both SAS and SDS scores and the VAS score.Univariate analysis identified sex,age,Wagner’s grade,presence of other complications,and smoking history as factors significantly associated with anxiety and depression.Multivariate analysis further confirmed that younger age,higher Wagner’s grade,and higher VAS scores were independent predictors of anxiety and depression.CONCLUSION This study reveals a significant positive correlation between anxiety,depression,and pain in patients with DFUs.This finding suggests that timely and effective pain intervention may be beneficial in alleviating negative emotions such as anxiety and depression.In addition,younger age(<50 years),higher Wagner’s grade,and higher VAS scores increase the risk of developing anxiety and depression in this patient population.

文摘Border-associated macrophages are located at the interface between the brain and the periphery, including the perivascular spaces, choroid plexus, and meninges. Until recently, the functions of border-associated macrophages have been poorly understood and largely overlooked. However, a recent study reported that border-associated macrophages participate in stroke-induced inflammation, although many details and the underlying mechanisms remain unclear. In this study, we performed a comprehensive single-cell analysis of mouse border-associated macrophages using sequencing data obtained from the Gene Expression Omnibus(GEO) database(GSE174574 and GSE225948). Differentially expressed genes were identified, and enrichment analysis was performed to identify the transcription profile of border-associated macrophages. CellChat analysis was conducted to determine the cell communication network of border-associated macrophages. Transcription factors were predicted using the ‘pySCENIC' tool. We found that, in response to hypoxia, borderassociated macrophages underwent dynamic transcriptional changes and participated in the regulation of inflammatory-related pathways. Notably, the tumor necrosis factor pathway was activated by border-associated macrophages following ischemic stroke. The pySCENIC analysis indicated that the activity of signal transducer and activator of transcription 3(Stat3) was obviously upregulated in stroke, suggesting that Stat3 inhibition may be a promising strategy for treating border-associated macrophages-induced neuroinflammation. Finally, we constructed an animal model to investigate the effects of border-associated macrophages depletion following a stroke. Treatment with liposomes containing clodronate significantly reduced infarct volume in the animals and improved neurological scores compared with untreated animals. Taken together, our results demonstrate comprehensive changes in border-associated macrophages following a stroke, providing a theoretical basis for targeting border-associated macrophages-induced neuroinflammation in stroke treatment.
