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 construct an intelligent segmentation and T-stage diagnostic model for esophageal cancer based on the DAEUnet and ConvNeXt networks using transfer learning.Methods Dicom raw data from 126 patients diagnosed with esophageal cancer between January 2018 and April 2022 were collected,including 100 cases from Department of Thoracic Surgery at the First Affiliated Hospital of Army Medical University and 26 cases from the Department of Thoracic Surgery at Shanxi Cancer Hospital.After data augmentation,a total of 60 275 images were obtained.The DAEUnet esophageal cancer intelligent segmentation network was built,and on this basis,3 classification networks,ConvNeXt,Swin Transformer,and ResNet were constructed for T-stage diagnosis of esophageal cancer.Results The Dice similarity coefficient(DSC)for esophageal cancer intelligent segmentation using the DAEUnet network was 0.82,and the DSC value of the esophagus,aorta,normal esophagus,mediastinal lymph nodes,and heart was 72.4％,87.5％,79.3％,60.5％ and 96.8％,respectively.Among the 3 T-stage diagnosis models for esophageal cancer,the ConvNeXt model performed the best,with a precision value for T1～T4 stages of 0.65,0.727,0.889 and 0.92,respectively,and an AUC value of 0.892,which were superior to the ResNet and Swin Transformer networks.Conclusion The proposed DAEUnet and ConvNeXt-based intelligent segmentation and T-stage diagnosis model for esophageal cancer improves T-stage accuracy and treatment efficiency.

Objective:To construct univariate and multivariate relapse free survival (RFS) prediction models for breast cancer patients with diabetes mellitus type 2 (T2DM) and to compare and select the model with higher predictive performance.Methods:A total of 912 breast cancer patients treated at the First Affiliated Hospital of Dalian Medical University from January 2010 to December 2016 were included, of which 202 patients had T2DM and 710 patients did not. Kaplan-Meier survival curve was drawn based on whether patients had T2DM, and log-rank test was performed based on whether patients had T2DM. All patients were randomly divided into a training set ( n=640) and a validation set ( n=272) at a ratio of 7∶3. Univariate and multivariate Cox proportional risk regression models were used to analyze RFS in breast cancer patients with the survival package. The "rms" package was employed to construct univariate and multivariate RFS prediction models for breast cancer patients with T2DM. Clinical decision curves and calibration curves were used to validate the models. The receiver operator characteristic (ROC) curve was used to compare and analyze the prediction performance of the two models. Results:There were no statistically significant differences between the training set and the validation set patients in terms of age, T2DM, surgical approach, axillary management methods, T stage, N stage, molecular sub-type, estrogen receptor (ER) 1, ER2, progesterone receptor (PR) , ER and PR consistency, Ki67, human epidermal growth factor receptor 2 (HER2) (all P>0.05) . There was a statistically significant difference in histological grade ( χ2=7.59, P=0.022) . Survival analysis showed that the 5-year RFS rate was 83.7% in patients with T2DM and 92.3% in patients without T2DM ( χ2=16.61, P<0.001) . Univariate analysis revealed that age ( HR=1.04, 95% CI: 1.03-1.06, P<0.001) , T2DM ( HR=2.31, 95% CI: 1.49-3.55, P<0.001) , surgical approach ( HR=2.39, 95% CI: 1.20-4.77, P=0.013) , axillary management methods ( HR=2.62, 95% CI: 1.72-3.98, P<0.001) , T stage (T 2: HR=2.13, 95% CI: 1.36-3.31, P<0.001; T 3: HR=6.90, 95% CI: 3.35-14.22, P<0.001) , N stage (N 2: HR=3.87, 95% CI: 2.12-7.07, P<0.001; N 3: HR=8.61, 95% CI: 4.71-15.75, P<0.001) , molecular sub-type (Luminal B: HR=2.74, 95% CI: 1.17-6.36, P=0.019; HER2 +: HR=3.64, 95% CI: 1.38-9.58, P=0.009; TNBC: HR=4.40, 95% CI: 1.71-11.34, P=0.002) , ER1 (>10%: HR=0.57, 95% CI: 0.37-0.90, P=0.016) , ER2 ( HR=0.57, 95% CI: 0.37-0.89, P=0.015) , and PR ( HR=0.56, 95% CI: 0.37-0.86, P=0.008) were all factors influencing RFS in breast cancer patients. Multivariate analysis demonstrated that age ( HR=1.04, 95% CI: 1.02-1.06, P<0.001) , T2DM ( HR=1.82, 95% CI: 1.16-2.85, P=0.009) , T stage (T 2: HR=1.60, 95% CI: 1.01-2.54, P=0.046; T 3: HR=2.64, 95% CI: 1.22-5.72, P=0.014) , N stage (N 2: HR=3.72, 95% CI: 2.01-6.88, P<0.001; N 3: HR=5.34, 95% CI: 2.78-10.25, P<0.001) , and ER1 (>10%: HR=0.63, 95% CI: 0.39-0.99, P=0.046) were independent factors influencing RFS in breast cancer patients. Based on the 10 and 5 variables with P<0.05 in the univariate and multivariate analyses respectively, the nomograms of the univariate and multivariate prediction models were constructed to evaluate the influence of factors such as T2DM on the postoperative RFS of breast cancer patients. Clinical decision curves and calibration curves indicated that both models had high predictive value for RFS in breast cancer patients, and the predictive results were highly consistent with the actual observed results. ROC curve analysis showed that there was no statistically significant difference in the area under the curve (AUC) of the two models for predicting the RFS rates of breast cancer patients in the training set and validation set at 36, 60, and 84 months (all P>0.05) , indicating that the predictive efficacy of the two models was comparable. The multivariate model is more suitable for clinical application because it uses fewer variables. Conclusions:Breast cancer patients with T2DM have poorer prognosis. Age, T2DM, T stage, N stage, and ER1 are independent factors influencing postoperative RFS in breast cancer patients. The multi-factor prediction model of RFS in breast cancer patients based on T2DM is more suitable for clinical application due to its higher predictive efficacy and fewer variables.

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 To understand the current situation of nutrition literacy of primary and secondary school students in Shijingshan District of Beijing, and analyze its influencing factors, and to put forward targeted suggestions for improving the students’ nutrition literacy and promoting their healthy growth. Methods A multi-stage stratified cluster sampling method was used to select 2480 primary and secondary school students and their parents from 5 primary schools, 3 middle schools and 1 high school in Shijingshan District. The multivariate logistic regression model was used to analyze the factors influencing the attainment rate of nutrition literacy. Results The median score of nutrition literacy of 2480 primary and secondary school students from grades 1 to 12 was 77.86 (in hundred-mark system), the quartile range (IQR) was 16.96, and the attainment rate of nutrition literacy was 42.46%. The cognitive level (45.12%) was higher than the skill level (41.20%) among students from grades 3 to 12. In terms of skills, the attainment rate of food preparation was the lowest, at 30.38%. The scores of nutrition literacy of girls were higher than those of boys, and the scores of primary school students were higher than those of secondary school students. Students with different levels of caregiver’s education, family income, and family food environment had different scores of nutrition literacy, and the differences were statistically significant (P<0.05). Multivariate logistic regression analysis showed that the attainment rate of nutrition literacy was closely related to student’s gender and study stage, caregiver’s education level, and family food environment. Conclusion The nutrition literacy of primary and secondary school students in Shijingshan District still needs to be improved, especially in the aspect of skills. Targeted nutrition education should be carried out.

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.

Objective:To investigate disease characteristics of patients with psoriatic arthritis (PsA) based on the PsA cohort in West China Hospital, so as to provide a reference for clinicians in its diagnosis, treatment, and evaluation strategy formulation.Methods:A cross-sectional study was carried out, and a descriptive analysis was conducted on clinical data from PsA patients who were treated at the Department of Dermatology, West China Hospital, Sichuan University between April 2, 2020, and January 21, 2025. Demographic characteristics, clinical manifestations, laboratory and imaging findings, and treatment modalities were analyzed.Results:A total of 530 PsA patients were included, of whom 332 (62.6%) were males and 198 (37.4%) were females, with ages of 44.1 ± 12.4 years. Skin lesions preceded joint symptoms in 452 patients (85.3%), with time intervals ( M [ Q1, Q3]) of 8.0 (3.0, 15.0) years. Overweight or obesity was observed in 319 patients (60.2%), and 188 (35.5%) had comorbid fatty liver. Peripheral joint involvement was common (485 cases, 91.5%), with the proximal interphalangeal joints being most frequently affected by tenderness (172 cases, 35.5%) and swelling (119 cases, 24.5%) ; the number of enthesitis cases identified by ultrasonography (116 cases, 23.9%) was significantly higher than that by clinical examination (82 cases, 15.5%) ; axial joint involvement was observed in 258 patients (48.7%), with the sacroiliac joints most commonly affected (201 cases, 77.9%). Regarding treatment, conventional systemic drugs were predominant in the treatment of psoriasis prior to the diagnosis of PsA; after the diagnosis of PsA, the number of patients receiving targeted therapies increased to 334 (63.0%), with interleukin-17 inhibitors being the most common (140 cases, 26.4%), followed by tumor necrosis factor-α inhibitors (106 cases, 20.0%) and Janus kinase inhibitors (39 cases, 7.4%) . Conclusions:PsA predominantly affects males over 40 years old and is characterized by preceding skin lesions, delayed diagnosis, and multiple comorbidities. High-frequency ultrasound has advantages in the early detection of peripheral enthesitis. Further attention is needed for managing comorbidities such as fatty liver and obesity-related metabolic conditions.

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.

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.
