Objective To systematically evaluate the efficacy and safety of traditional Chinese medicine (TCM) compound in treating pulmonary nodules, providing evidence-based medical evidence for TCM intervention in pulmonary nodules. Methods Computer search of PubMed, CNKI, Wanfang, VIP, and SinoMed was conducted to select randomized controlled trials (RCTs) of TCM compound intervention in pulmonary nodules, with the retrieval time from the inception to November 29, 2023. The Cochrane bias risk assessment tool was used to evaluate the quality of the included studies, and Review Manager 5.4 was used for Meta-analysis. Results A total of 18 RCTs were included, covering 8 provinces across the country, with a total sample size of 1301 patients. The TCM compounds used in the included studies all incorporated the method of dissolving phlegm and dissipating nodules. There was a high risk of bias uncertainty in the included studies. Meta-analysis results suggested that TCM compound could significantly reduce the diameter of pulmonary nodules [MD=−1.41, 95%CI (−1.70, −1.13), P<0.001], decrease the number of nodules [MD=−0.37, 95%CI (−0.73, −0.01), P=0.05], alleviate clinical symptoms [MD=−4.84, 95%CI (−6.04, −3.64), P<0.001], and improve lung function [forced expiratory volume in one second (FEV1), MD=0.55, 95%CI (0.09, 1.01), P=0.02; FEV1/forced vital capacity, MD=6.12, 95%CI (4.47, 7.78), P<0.001]. However, there was no statistically significant difference in the probability of malignancy between the experimental group and the control group [MD=−0.01, 95%CI (−0.01, 0.00), P=0.09]. Conclusion TCM compound can significantly reduce the diameter of pulmonary nodules, decrease the number of nodules, alleviate clinical symptoms, and improve lung function, but future multicenter, large-sample, high-quality RCTs are still needed to further explore and verify this conclusion.

ObjectiveTo analyze the characteristics and life loss of injury-related deaths among the registered residents in Anji County from 2015 to 2024, and to provide a reference for conducting targeted injury prevention and control efforts. MethodsData on injury-related deaths among the registered residents in Anji County from 2015 to 2024 were collected from the Chronic Disease Surveillance and Management System of Zhejiang Province. Indicators including the crude mortality rate (CMR), standardized mortality rate (SMR), proportion, potential years of life lost (PYLL), average years of life lost (AYLL) and potential years of life lost rate (PYLLR) were calculated. The annual trends in injury mortality were evaluated using average annual percent change (AAPC). ResultsFrom 2015 to 2024, a total of 3 800 injury deaths were reported in Anji County, accounting for 11.94% of all deaths and ranking as the fourth leading cause of death. The CMR was 80.65/100 000 and showed an upward trend (AAPC=3.53%, P=0.003), while the SMR was 50.68/100 000 with no significant trend (AAPC=-1.47%, P=0.196). The CMR was higher in males (95.03/100 000) than in females (66.49/100 000). The top five causes of injury-related deaths were accidental falls, traffic accidents, suicide, drowning and accidental poisoning. The top two injury-related causes of death varied by age group: for the 0‒<15 age group, they were accidental falls, traffic accidents (with drowning tied for second place); for the 15‒<45 age group, they were traffic accidents and suicide; for the 45‒<65 age group, they were traffic accidents and accidental falls; and for the 65‒105 age group, they were accidental falls and traffic accidents. From 2015 to 2024, the total PYLL due to injury deaths was 47 464.00 person-years, the AYLL was 12.49 years, and the PYLLR was 10.07‰. ConclusionFrom 2015 to 2024, the injury crude mortality rate in Anji County was relatively high and showed an upward trend. Targeted interventions based on demographic characteristics and injury types should be implemented to reduce injury mortality.

Objective To analyze the distribution characteristics of 13 common respiratory pathogens in children in Zibo area from 2020 to 2022.Methods A total of 3091 hospitalized children with respiratory infections admitted to Zibo Maternal and Child Health Hospital from January 2020 to December 2022 were selected as the subjects.Throat swabs or bronchoalveolar lavage fluid samples were collected from the patients,and 13 common respiratory pathogens were tested to analyze the distribution differences among different genders,ages,and seasons.Results Among 3091 pediatric patients,1794 were found to be infected with pathogens.The top three pathogens were Mycoplasma pneumoniae,rhinovirus,and respiratory syncytial virus(RSV).The single infection rate was 47.75％,while the mixed infection rate was 10.28％,with the most common scenario being a mixed infection of two pathogens.There were statistically significant differences in the pathogen profiles across different age groups(P＜0.001):infants had the highest detection rate of RSV,young children were primarily infected with rhinovirus,preschool and school-age children were predominantly infected with Mycoplasma pneumoniae.Seasonal distribution showed that the highest positive rate was in autumn,while the lowest was in spring(P＜0.05).In spring,the main pathogens were rhinovirus and Mycoplasma pneumoniae;in summer,they were rhinovirus and parainfluenza virus;in autumn,they were Mycoplasma pneumoniae and RSV;and in winter,the detection rates of Mycoplasma pneumoniae and influenza B virus were higher.Conclusion From 2020 to 2022,Mycoplasma pneumoniae,rhinovirus and RSV were the main pathogens of children's respiratory tract infection in Zibo area,and there were significant differences in the distribution of pathogens among different ages and seasons.

Objective:To develop a scientific and practical questionnaire for general practice residents, and to conduct multidimensional and comprehensive evaluation of the quality of general practice teaching clinics.Methods:A preliminary draft of the questionnaire items was formulated based on a literature review and in-depth interviews. The Delphi method was employed to conduct two rounds of consultation with 14 experts. Following revisions, a convenience sampling method was used to invite general practice residents from three standardized residency training bases to test the reliability and validity of the questionnaire.Results:The questionnaire consisted of 23 items, covering the three dimensions of preparation, implementation process, and comprehensive evaluation of the teaching clinics. The response rates for the two rounds of the expert consultation were both 100.00%, with expert authority coefficients of 0.89 and 0.90, respectively. The overall Cronbach's α coefficient of the questionnaire was 0.93, and the correlation coefficients between each item score and the total score were all >0.30. Structural validity analysis revealed that three common factors were extracted from the questionnaire, with a cumulative variance contribution rate of 77.89%. Conclusions:The General Practice Teaching Clinic Quality Evaluation Questionnaire for Residents developed in this study demonstrates high reliability and validity. The questionnaire provides a scientific basis for the standardized assessment of teaching quality in general practice clinics. By incorporating resident feedback on the teaching process, the questionnaire promotes the development of a teaching clinic quality improvement mechanism focused on residents and plays a significant role in enhancing the teaching capabilities of supervising physicians in clinics.

Background and Aims:Acute inferior vena cava thrombosis(IVCT)commonly occurs secondary to inferior vena cava filter(VCF)implantation.If not promptly treated,it may lead to serious complications such as bilateral lower limb swelling and pulmonary embolism and can also reduce the likelihood of successful filter retrieval.Percutaneous mechanical thrombectomy(PMT)and catheter-directed thrombolysis(CDT)are currently the main interventional treatments for IVCT,but comparative studies evaluating their efficacy and safety remain limited.This study was to conduct a prospective randomized controlled trial to compare the clinical efficacy and safety of AngioJet mechanical thrombectomy versus conventional CDT in the treatment of acute IVCT and to explore factors influencing filter retrieval rates,thereby providing evidence-based guidance for clinical decision-making.Methods:From January 2022 to December 2024,patients diagnosed with acute IVCT following VCF implantation were prospectively enrolled at the Department of Vascular Surgery,Beijing Jishuitan Hospital,Capital Medical University.Patients were randomly assigned to either the CDT group(n=46)or the PMT group(n=48)according to the interventional procedure used.The two groups were compared in terms of filter retrieval rates,thrombus clearance outcomes,operative time,thrombolytic drug dosage,and incidence of complications.Logistic regression analysis was used to identify factors associated with primary filter retrieval.Results:A total of 94 patients were enrolled,with 46 in the CDT group and 48 in the PMT group.Compared to the CDT group,the PMT group demonstrated a significantly higher primary filter retrieval rate(77.1%vs.43.5%),grade Ⅲ thrombus clearance rate(70.8%vs.37.0%),and better postoperative thrombus scores.Additionally,the PMT group required lower urokinase doses and shorter thrombolysis duration(all P<0.05).The overall filter retrieval rate and 3-month IVC patency were similar between groups,both exceeding 93%.Regarding safety,the CDT group had a higher incidence of catheter-related infections and medical adhesive-related skin injury,while vagal reflex symptoms were more frequent in the PMT group.Logistic regression analysis identified thrombus clearance rate as an independent factor significantly associated with primary filter retrieval in the PMT group(OR=190.773,P<0.05).Conclusion:Compared to CDT,AngioJet mechanical thrombectomy combined with manual aspiration achieves higher thrombus clearance and primary filter retrieval rates in the treatment of acute IVCT while also reducing thrombolysis duration and drug dosage.However,attention should be paid to the increased risk of vagal reflex symptoms.There was no significant difference between the two groups in secondary filter retrieval rates or long-term IVC patency.The choice of intervention should be based on the patient's condition,timing of filter retrieval,and individualized clinical considerations.

Objective:Multivariate logistic regression analysis was performed to analyze the risk factors for intensive care unit-acquired weakness (ICU-AW) in critically ill patients.Methods:A total of 220 critically ill patients who were admitted to Intensive Care Unit, The First Hospital of Jiaxing from January 2020 to January 2022 were included in this study. The incidence of ICU-AW was recorded. Univariate analysis was conducted to investigate the factors related to ICU-AW, while multiple logistic regression analysis was performed to identify independent risk factors for ICU-AW in critically ill patients.Results:Among the 220 critically ill patients, 64 developed ICU-AW, resulting in an incidence of 29.1% (64/220). There were no significant differences in sex, age, history of alcoholism, history of smoking, marital status, hypertension, diabetes, or use of glucocorticoid (methylprednisolone sodium succinate for injection) between the ICU-AW group and the non-ICU-AW group (all P > 0.05). The proportion of patients with sepsis in the ICU-AW group was higher than that in the non-ICU-AW group [46.9% (30/64) vs. 15.4% (24/156)]. The proportion of patients who were immobilized in the ICU-AW group was higher than that in the non-ICU-AW group [89.1% (37/64) vs. 64.1% (100/156)]. The use of nerve blocker (vecuronium bromide for injection) was more prevalent in the ICU-AW group than that in the non-ICU-AW group [57.8% (37/64) vs. 23.1% (36/156)]. The Acute Physiology And Chronic Health Evaluation Ⅱ score in the ICU-AW group was higher than that in the non-ICU-AW group [16 (11, 23) vs. 12 (8, 17)]. The duration of mechanical ventilation in the ICU-AW group was longer than that in the non-ICU-AW group [8 (4, 13) days vs. 4 (3, 6) days]. The length of hospital stay in the ICU-AW group was longer than that in the non-ICU-AW group [10 (7, 17) days vs. 7 (5, 11) days]. The blood lactate level in the ICU-AW group was higher than that in the non-ICU-AW group [2 (1, 2) mmol/L vs. 1 (1, 2) mmol/L]. All differences were statistically significant ( χ2 = 24.30, 13.83, 24.70, Z = 3.83, 4.59, 3.97, 2.70, all P < 0.05). The results of the univariate analysis, when included in the multivariate logistic regression analysis, showed that sepsis, immobilization, duration of mechanical ventilation, blood lactate level, and Acute Physiology And Chronic Health Evaluation Ⅱ score were independent risk factors for ICU-AW (all P < 0.05). Conclusions:The incidence of ICU-AW is high and the risk factors for ICU-AW are complex. Therefore, targeted control of high-risk factors should be actively performed to prevent and treat ICU-AW.

AIM:To explore the mechanism of doxorubicin/copper(DOX/Cu)complex induced copper death in hepatocellular carcinoma cells.METHODS:Human hepatocellular carcinoma cell line Huh7 was treated with DOX/Cu 0,2.5,4,7.5,10 and 12.5 μmol/L.The cell viability was detected by CCK-8 method.The cell proliferation level was observed by laser microscopy and proliferation kit.The cell invasion ability was determined by cell scratch assay.The flow cytometry was used to de-tect intracellular reactive oxygen species(ROS)and copper ion levels.And the western blot was used to detect intracellular iron-sulfur cluster proteins expression levels.RESULTS:With the increase of DOX/Cu concentration,cell viability,cell prolifera-tion and invasion ability decreased gradually.The copper ion chelating agent(TTM)can significantly restore the effects of DOX/Cu on cell viability.After DOX/Cu treatment,intracellular copper ion and ROS levels related to coproptosis were significantly increased,accompanied by the loss of iron-sulfur cluster proteins.CONCLUSION:DOX/Cu can inhibit hepatocellular carcinoma cells through cuproptosis.

Cholesterol(CH)plays a crucial role in enhancing the membrane stability of drug delivery systems(DDS).However,its association with conditions such as hyperlipidemia often leads to criticism,overshadowing its influence on the biological effects of formulations.In this study,we reevaluated the delivery effect of CH using widely applied lipid microspheres(LM)as a model DDS.We conducted comprehensive in-vestigations into the impact of CH on the distribution,cell uptake,and protein corona(PC)of LM at sites of cardiovascular inflammatory injury.The results demonstrated that moderate CH promoted the accumulation of LM at inflamed cardiac and vascular sites without exacerbating damage while partially mitigating pathological damage.Then,the slow cellular uptake rate observed for CH@LM contributed to a prolonged duration of drug efficacy.Network pharmacology and molecular docking analyses revealed that CH depended on LM and exerted its biological effects by modulating peroxisome proliferator-activated receptor gamma(PPAR-γ)expression in vascular endothelial cells and estrogen receptor alpha(ERα)protein levels in myocardial cells,thereby enhancing LM uptake at cardiovascular inflam-mation sites.Proteomics analysis unveiled a serum adsorption pattern for CH@LM under inflammatory conditions showing significant adsorption with CH metabolism-related apolipoprotein family members such as apolipoprotein A-V(Apoa5);this may be a major contributing factor to their prolonged circu-lation in vivo and explains why CH enhances the distribution of LM at cardiovascular inflammatory injury sites.It should be noted that changes in cell types and physiological environments can also influence the biological behavior of formulations.The findings enhance the conceptualization of CH and LM delivery,providing novel strategies for investigating prescription factors' bioactivity.
