Metho...Objective: To explore the application effect of pulmonary rehabilitation nursing intervention in patients with stable chronic obstructive pulmonary disease (COPD) and evaluate its impact on nursing satisfaction. Methods: A total of 120 patients with stable COPD admitted to our hospital from February 2023 to February 2025 were selected and divided into a control group and an observation group according to the order of admission, with 60 cases in each group. The control group received routine nursing care, while the observation group received systematic pulmonary rehabilitation nursing intervention on this basis. Pulmonary function indicators, 6-minute walk test (6MWT) distance, COPD Assessment Test (CAT) scores, incidence of acute exacerbations, and nursing satisfaction were compared between the two groups after nursing. Results: After nursing, the FEV1, FVC, and FEV1/FVC in the observation group were significantly higher than those in the control group, the 6MWT distance significantly increased, and the CAT scores significantly decreased, with statistically significant differences (p < 0.05). The incidence of acute exacerbations in the observation group was lower than that in the control group, and the nursing satisfaction score was higher (p < 0.05). Conclusion: Pulmonary rehabilitation nursing intervention can effectively improve pulmonary function, exercise tolerance, and symptom control in patients with stable COPD, and significantly enhance nursing satisfaction, making it worthy of further clinical promotion.展开更多

文摘Chronic obstructive pulmonary disease(COPD),a disease responsible for early mortality worldwide,is well accepted to be associated with periodontitis epidemiologically.Although both of the diseases are the multi-microbial inflammatory disease,the precise underlying mechanisms by which periodontitis influences the progression of COPD remains largely unknown.Here,we established COPD accompanied with periodontitis mouse models and observed the pronounced progress in pulmonary symptoms and histopathology,cha racterized by poorer respiratory function,thicke ned bronchial walls,and increased neutrophils infiltration in lung tissue.Mechanistically,periodontitis pathogen Porphyromonas gingivalis(P.gingivalis)relocated in the lung through the respiratory tract and LPS from P.gingivalis promoted the secretion of chemokines CXCL2 and G-CSF of alveolar epithelial cells through NF-κB and p38 MAPK pathways to recruit neutrophils.Furthermore,exposure to P.gingivalis of infiltrated neutrophils released matrix metallopeptidase-8(MMP-8)and neutrophil elastase(NE),which aggravated airway inflammation and tissue damage.These findings indicated that periodontitis could exacerbate COPD via its pathogen P.gingivalis,which translocated in the lung and stimulated neutrophil chemotaxis and activation in the lung.

文摘Chronic obstructive pulmonary disease(COPD)is one of the leading causes of death and disability worldwide.Its complex etiology involves factors such as smoking,air pollution,genetic susceptibility,and social environment.With the accelerating global aging population and urbanization,the incidence and burden of COPD continue to rise.Current treatment strategies for COPD are relatively conservative,primarily focusing on bronchodilators,inhaled corticosteroids,and long-term oxygen therapy.Although these approaches can alleviate symptoms and slow disease progression to some ex-tent,they fail to effectively target the underlying mechanisms of the disease,leaving an unmet clinical need for more-effective therapies.This highlights the urgency of de-veloping innovative drugs that are both safe and efficacious to address the challenges in COPD treatment.As a traditional Chinese medicine with a long history,Colla corii asini has garnered significant attention for its diverse pharmacological effects and fa-vorable safety profile.Research has shown that Colla corii asini possesses multiple bio-logical activities,including hematopoiesis,nourishing the lungs,enhancing immunity,anti-infection,antiaging,antitumor,and antifatigue effects.Moreover,it has demon-strated potential in regulating oxidative stress,immune imbalance,and inflammatory responses.Recent evidence suggests that Colla corii asini may play a protective role in lung function through multitarget and multipathway mechanisms.Based on previ-ous research findings,this paper explores the potential therapeutic value of Colla corii asini in COPD treatment by addressing the current clinical management challenges and identifying potential therapeutic targets.It also integrates the pharmacological effects of Colla corii asini into a broader treatment context,providing new perspec-tives for comprehensive COPD management and laying the theoretical foundation for its modernization and innovative application.

文摘Objective:To investigate the quantitative assessment efficacy of chest CT combined with serum Vanin-1 and SPP1 in determining the progression stage of chronic obstructive pulmonary disease(COPD).Methods:A total of 100 COPD subjects from our hospital from January 2020 to December 2023 were included and randomly divided into a healthy control group and an experimental group(50 cases each).The healthy control group underwent slow vital capacity measurement using a spirometer,while the experimental group underwent high-resolution thin-slice CT scans and serum Vanin-1 and SPP1 concentration measurements.Pulmonary function parameters,symptom burden,biomarker concentrations,and imaging characteristics were compared between the two groups.Results:The FEV1/FVC ratio in the experimental group(58.3±7.2)was lower than that in the healthy control group(92.1±4.8);the total CAT score(22.4±3.5)was higher than that in the healthy control group(3.1±1.2);both Vanin-1(18.7±2.3μg/L)and SPP1(25.6±4.1μg/L)levels were higher than those in the healthy control group;LAA%-950(38.7±6.2%)and WA%(68.5±5.3%)were significantly higher than those in the healthy control group(all p<0.001).Conclusion:Chest CT combined with serum Vanin-1 and SPP1 can accurately quantify the pathological progression of COPD,providing a dual basis for clinical staging and individualized intervention.
文摘Objective: To explore the application effect of pulmonary rehabilitation nursing intervention in patients with stable chronic obstructive pulmonary disease (COPD) and evaluate its impact on nursing satisfaction. Methods: A total of 120 patients with stable COPD admitted to our hospital from February 2023 to February 2025 were selected and divided into a control group and an observation group according to the order of admission, with 60 cases in each group. The control group received routine nursing care, while the observation group received systematic pulmonary rehabilitation nursing intervention on this basis. Pulmonary function indicators, 6-minute walk test (6MWT) distance, COPD Assessment Test (CAT) scores, incidence of acute exacerbations, and nursing satisfaction were compared between the two groups after nursing. Results: After nursing, the FEV1, FVC, and FEV1/FVC in the observation group were significantly higher than those in the control group, the 6MWT distance significantly increased, and the CAT scores significantly decreased, with statistically significant differences (p < 0.05). The incidence of acute exacerbations in the observation group was lower than that in the control group, and the nursing satisfaction score was higher (p < 0.05). Conclusion: Pulmonary rehabilitation nursing intervention can effectively improve pulmonary function, exercise tolerance, and symptom control in patients with stable COPD, and significantly enhance nursing satisfaction, making it worthy of further clinical promotion.
文摘BACKGROUND Hepatocellular carcinoma(HCC)is a major type of liver cancer worldwide.In advanced stages,portal vein tumor thrombosis(PVTT)and jaundice are common,whereas obstructive jaundice(OJ)is relatively rare.Both conditions markedly reduce survival and increase therapeutic complexity.Recently,hepatic artery infusion chemotherapy(HAIC)in combination with targeted immunotherapy has shown promise for advanced HCC.CASE SUMMARY We report a 47-year-old male with advanced HCC complicated by PVTT and OJ,who was admitted with marked jaundice of the skin and sclera.Imaging revealed a large hepatic mass(14.5 cm×11.3 cm)in the right lobe with associated portal vein tumor thrombus.The tertiary bile duct was only mildly dilated,making percutaneous transhepatic cholangiography drainage infeasible.The patient underwent reduced-dose HAIC,which resulted in significant tumor shrinkage and marked reduction in serum bilirubin.This improvement enabled sequential treatment with lenvatinib and camrelizumab.After six cycles,both liver function and alphafetoprotein levels improved.The patient achieved a progression-free survival of 20 months and an overall survival of 29 months.CONCLUSION HAIC can treat high-bilirubin HCC with PVTT and OJ,allowing for subsequent targeted immunotherapy.

文摘Objective This study investigated the effect of reducing soluble epoxide hydrolase(sEH,encoded by the Ephx2 gene)on the mediation of EETs metabolism during ferroptosis in emphysema in vivo.Methods Male C57BL/6J wild-type(WT)and Ephx2^(-/-)mice received whole-body exposure to either cigarette smoke(CS)or air for 16 weeks.The alveolar structure,pulmonary function,lung tissue morphology,cell death,and ferroptosis levels were assessed following exposure.Results CS exposure caused emphysema,reduced pulmonary function,and induced ferroptosis in mice compared with exposure to air.In contrast,following CS exposure,Ephx2^(-/-)mice exhibited significantly lower levels of emphysema,impaired lung function,lung cell death,intracellular iron,lipid reactive oxygen species,cyclooxygenase-2,4-hydroxynonenal,and malondialdehyde levels than those of WT mice.However,Ephx2^(-/-)mice exhibited higher levels of glutathione and ferritin heavy chain 1 than those of WT mice.SLC7A11 expression was significantly reduced,whereas glutathione peroxidase 4 expression was markedly increased in Ephx2^(-/-)mice compared with WT mice.Statistically significant differences(P<0.05)were observed.Conclusion These results suggest that Ephx2 deficiency inhibits ferroptosis to alleviate CS-induced emphysema,primarily by mitigating its inhibitory effect on the cystine/glutathione/glutathione peroxidase 4 axis.Therefore,Ephx2 represents an effective therapeutic target in CS-induced chronic obstructive pulmonary disease(COPD).

文摘Objective Patients with atherosclerotic cardiovascular disease(ASCVD)following percutaneous coronary intervention(PCI)are classified as very-high-risk individuals in cardiovascular disease(CVD)risk stratification.The distribution pattern of traditional Chinese medicine(TCM)syndromes in this patient population,as well as its association with blood lipid profiles and clinical prognosis,remains unclear.The present prospective cohort study aims to investigate these correlations,thereby providing insights to enrich the research fields.Methods We enrolled consecutive patients with ASCVD who underwent PCI at the Integrated Cardiology Unit of China-Japan Friendship Hospital between September 1,2020 and December 31,2022.Demographics and clinical characteristics,signs and symptoms defining each TCM syndrome,and fasting venous blood samples were collected at baseline and follow up or upon major adverse cardiovascular events(MACEs).We analyzed the correlation between TCM syndromes,blood lipid profiles,and MACEs,and developed a new joint prognostic model incorporating both TCM syndromes and blood lipids using logistic regression.The analyses were based on detailed baseline and one-year follow-up data.Results A per-protocol analysis was performed on 586 patients with complete data ultimately.During the one-year follow-up,174 patients(29.69%)experienced a MACE.We performed statistical analyses on comorbidities,medication,and biochemical indicators across groups defined by TCM syndrome differentiation.When comparing different TCM syndromes,no significant differences were found in age,body mass index(BMI),history of revascularization,comorbidities,family history of CVD,smoking or drinking,or statin intensity(P>0.05).Patients with intertwined phlegm and blood stasis syndrome exhibited significantly higher levels of total cholesterol(TC,5.27±1.18 mmol/L,P<0.001),triglyceride(TG,1.96±1.33 mmol/L,P=0.008),low-density lipoprotein cholesterol(LDL-C,3.35±0.79 mmol/L,P<0.001),and high-density lipoprotein cholesterol(HDL-C,1.24±0.81 mmol/L,P<0.001)compared with those with other TCM syndromes combined.A multivariable logistic regression model was constructed to predict MACEs.The model included TCM syndrome type[with intertwined phlegm and blood stasis as a predictor,adjusted odds ratio(OR)=1.413,95%confidence interval(CI):0.517–3.864,P=0.501],age(adjusted OR=0.97,95%CI:0.955–1.001,P=0.057),male gender(adjusted OR=0.698,95%CI:0.416–1.170,P=0.173),TC(adjusted OR=1.004,95%CI:0.513–1.965,P=0.990),and LDL-C(adjusted OR=5.825,95%CI:2.214–15.326,P<0.001).This model demonstrated good discriminatory ability for MACEs in post-PCI ASCVD patients[the area under the receiver operating characteristic(ROC)curve(AUC)=0.865,95%CI:0.816–0.914].Conclusion The intertwined phlegm and blood stasis TCM syndrome is associated with a distinct atherogenic lipid profile characterized by elevated levels of TC and LDL-C.The prognostic model that incorporates this TCM syndrome type along with conventional lipid parameters(TC and LDL-C)shows good discriminatory ability for predicting MACEs in ASCVD patients after PCI,underscoring the potential clinical utility of integrating TCM syndrome differentiation into CVD risk assessment.

文摘BACKGROUND The degree of obstruction plays an important role in decision-making for obstructive colorectal cancer(OCRC).The existing assessment still relies on the colorectal obstruction scoring system(CROSS)which is based on a comprehensive analysis of patients’complaints and eating conditions.The data collection relies on subjective descriptions and lacks objective parameters.Therefore,a scoring system for the evaluation of computed tomography-based obstructive degree(CTOD)is urgently required for OCRC.AIM To explore the relationship between CTOD and CROSS and to determine whether CTOD could affect the short-term and long-term prognosis.METHODS Of 173 patients were enrolled.CTOD was obtained using k-means,the ratio of proximal to distal obstruction,and the proportion of nonparenchymal areas at the site of obstruction.CTOD was integrated with the CROSS to analyze the effect of emergency intervention on complications.Short-term and long-term outcomes were compared between the groups.RESULTS CTOD severe obstruction(CTOD grade 3)was an independent risk factor[odds ratio(OR)=3.390,95%confidence interval(CI):1.340-8.570,P=0.010]via multivariate analysis of short-term outcomes,while CROSS grade was not.In the CTOD-CROSS grade system,for the non-severe obstructive(CTOD 1-2 to CROSS 1-4)group,the complication rate of emergency interventions was significantly higher than that of non-emergency interventions(71.4%vs 41.8%,P=0.040).The postoperative pneumonia rate was higher in the emergency intervention group than in the non-severe obstructive group(35.7%vs 8.9%,P=0.020).However,CTOD grade was not an independent risk factor of overall survival and progression-free survival.CONCLUSION CTOD was useful in preoperative decision-making to avoid unnecessary emergency interventions and complications.

文摘Dear Editor,Inguinal hernia repair(IHR)performed during childhood is a prevalent etiological factor for obstructive azoospermia(OA)attributed to vasal injury.OA couples can achieve pregnancy through intracytoplasmic sperm injection or natural pregnancy after microsurgical anastomosis.Recent advancements have highlighted the potential utility of laparoscopy-assisted vasovasostomy for treating OA caused by childhood herniorrhaphy.
文摘Male infertility has seen an increase in prevalence with cases of azoospermia estimated to affect 10%–15%of infertile men.Confirmation of azoospermia subsequently necessitates an early causal differentiation between obstructive azoospermia(OA)and nonobstructive azoospermia(NOA).Although less common when compared to NOA,OA can represent upward 20%–40%of cases of azoospermia.While there are a multitude of etiologies responsible for causing NOA and OA,correctly distinguishing between the two types of azoospermia has profound implications in managing the infertile male.This review represents an amalgamation of the current guidelines and literature which will supply the reproductive physician with a diagnostic armamentarium to properly distinguish between NOA and OA,therefore providing the best possible care to the infertile couple.
文摘Objective:To investigate the clinical efficacy of levofloxacin combined with ambroxol in the treatment of elderly patients with chronic obstructive pulmonary disease(COPD)and pulmonary infection.Methods:A total of 80 elderly COPD patients with pulmonary infection,treated between December 2022 and November 2023,were randomly divided into a control group and an observation group,with 40 cases in each group.The control group was treated with levofloxacin hydrochloride,while the observation group received ambroxol hydrochloride injection in addition to the treatment in the control group.Laboratory indices(white blood cell count,procalcitonin,C-reactive protein,and apolipoprotein E levels),imaging-based pulmonary lesion absorption time,hospital stay,and incidence of adverse reactions were compared between the two groups.Results:After treatment,the biochemical indices of the observation group were significantly lower than those of the control group,with highly significant differences(P<0.001).Compared to the control group,the imaging-based pulmonary lesion absorption time and hospital stay of the observation group were significantly shorter(P<0.001).Additionally,the incidence of adverse reactions in the observation group was significantly lower than in the control group(P<0.05).Conclusion:Levofloxacin combined with ambroxol demonstrates advantages in improving biochemical indices,shortening imaging-based pulmonary lesion absorption time and hospital stay,and reducing adverse reaction rates in elderly COPD patients with pulmonary infection.It holds significant clinical application value.

文摘BACKGROUND The correlation conclusions between self-management,frailty,and quality of life(QoL)of chronic obstructive pulmonary disease(COPD)patients are inconsistent.AIM To comprehensively assess the current status of self-management,psychological cognitive impairment,and QoL in elderly patients with COPD.METHODS Convenient sampling was employed to select 312 elderly patients with COPD who were receiving treatment in the respiratory and critical care medicine department of a tertiary grade A hospital from November 2023 to February 2024.The study utilized demographic information and clinical characteristics,selfmanagement behavior,occurrence of psychological cognitive impairment,and QoL as evaluated through general information questionnaires,the COPD patient self-management scale,simple frailty scale,simple mental status scale,clinical dementia assessment scale,and the clinical COPD assessment test questionnaire.This research aims to describe the current status and correlations among selfmanagement behavior,cognitive impairment occurrence,and QoL.RESULTS The average score for self-management behavior in elderly COPD patients was 136.00(119.00,164.50),indicating a moderate level overall.There were 98 cases of cognitive impairment,accounting for 31.4%,with a mental status score of 3(2,3.75).The average QoL score was 24(19,28),indicating a low level.Additionally,there was a negative correlation between total self-management behavior score and cognitive impairment occurrence(r=-0.589,P<0.001),and QoL total score(r=-0.409,P<0.001).Cognitive impairment occurrence was positively correlated with QoL total score(r=0.345,P<0.001).Disease course and self-management behavior score were independent factors affecting the total QoL score in elderly COPD patients(P<0.05).CONCLUSION The self-management behavior of elderly patients with COPD is at a moderate level.However,the occurrence of cognitive impairment is high and significantly influenced by disease course,level of self-management,and mental status.The QoL is low,emphasizing the urgent need to intervene in the self-management behaviors of elderly COPD patients,actively reduce the occurrence of cognitive impairment,and mitigate the impact of the disease on QoL.
文摘This letter responds to Wang et al's recent publication on endoscopic biliary stenting for malignant obstructive jaundice(MOJ)by offering constructive feedback and suggestions for future research.We commend the authors for their comprehensive study design and execution,which included a clear delineation of study groups and a robust set of outcome measures.We suggest that future studies incorporate additional biomarkers,such as serum levels of liver enzymes and bilirubin,to provide a more nuanced understanding of liver function changes post-intervention.The study's focus on short-term survival rates is appreciated,but we recommend exploring longer-term follow-up periods to capture the full spectrum of survival outcomes.Additionally,the inclusion of quality of life assessments using validated instruments could offer a more holistic view of patient outcomes.From a critical care perspective,we advocate for the integration of advanced imaging techniques to better characterize biliary anatomy and potentially predict treatment response or complications.We believe that incor-porating these suggestions could enhance the understanding of endoscopic biliary stenting's role in MOJ management and its impact on patient outcomes,influ-encing future clinical guidelines and practice.

文摘BACKGROUND Obstructive sleep apnea-hypopnea syndrome(OSAHS)is a highly prevalent sleep-related respiratory disorder associated with serious health risks.Although polysomnography is the clinical gold standard for diagnosis,it is expensive,in-convenient,and unsuitable for population-level screening due to the need for professional scoring and overnight monitoring.AIM To address these limitations,this review aims to systematically analyze recent ad-vances in deep learning–based OSAHS detection methods using snoring sounds,particularly focusing on graphical signal representations and network architec-tures.METHODS A comprehensive literature search was conducted following the PRISMA 2009 guidelines,covering publications from 2010 to 2025.Studies were included based on predefined criteria involving the use of deep learning models on snoring sounds transformed into graphical representations such as spectrograms and scalograms.A total of 14 studies were selected for in-depth analysis.RESULTS This review summarizes the types of signal modalities,datasets,feature extraction methods,and classification frameworks used in the current literatures.The strengths and limitations of different deep network architectures are evaluated.CONCLUSION Challenges such as dataset variability,generalizability,model interpretability,and deployment feasibility are also discussed.Future directions highlight the importance of explainable artificial intelligence and domain-adaptive learning for clinically viable OSAHS diagnostic tools.
文摘Endothelial dysfunction is a key factor linking obstructive sleep apnea hypopnea syndrome(OSAHS)with cardiovascular diseases.In this study,we used advanced proteomics and metabolomics approaches to investigate the impact of extracellular vesicles(EVs)derived from the serum of OSAHS patients on endothelial function.Our multi-omics analysis identified dysregulated pathways related to fatty acid metabolism,apoptosis regulation,and inflammatory responses,highlighting fatty acid synthase(FASN)as a crucial player in OSAHS-induced endothelial dysfunction.Both in vitro and in vivo experiments demonstrated that FASN-enriched EVs impair endothelial cell viability and disrupt metabolic homeostasis,offering new insights for the development of targeted therapies for cardiovascular complications associated with OSAHS.
