Background: This study was performed to characterize the incidence, costs, and risk factors associated with renal and cardiovascular adverse outcomes following primary percutaneous coronary intervention (pPCI) in patients with ST-elevation myocardial infarction (STEMI). Methods: Patients with STEMI who underwent pPCI using iso-osmolar contrast were enrolled at 39 centers. The incidence of acute kidney injury (AKI) and major adverse renal and cardiovascular events (MARCE) was analyzed, as well as inpatient costs. Logistic regression analysis was performed to identify risk factors. Results: Among 2,293 patients, the incidence of AKI and MARCE within 72 hours post-pPCI was 4.14% (n = 95) and 4.40% (n = 101), respectively. AKI and/or MARCE were associated with systolic blood pressure (AKI: odds ratio [OR], 1.009; 95% confidence interval [CI], 1.000–1.018), hypertension (AKI: OR, 1.815; 95% CI, 1.133–2.906; MARCE: OR, 1.760;95% CI, 1.118–2.769), anterior wall infarction (AKI: OR, 1.895; 95% CI, 1.196–3.004; MARCE:OR, 1.939; 95% CI, 1.240–3.032), Killip class (AKI: OR, 1.465; 95% CI, 1.117–1.922; MARCE:OR, 1.467; 95% CI, 1.131–1.903), and serum creatinine (SCr; MARCE: OR, 1.006; 95% CI, 1.000–1.012). Hospitalization costs for patients with STEMI who developed AKI or MARCE were significantly higher than for those without AKI (9,595 ± 5,795 vs. 8,279 ± 3,872 USD, P = 0.003) or without MARCE (9,890 ± 5,616 vs. 8,255 ± 3,859 USD, P < 0.001). Conclusions In patients with STEMI undergoing pPCI with iso-osmolar contrast, the incidence of AKI and MARCE was associated with higher hospitalization costs. Systolic blood pressure, hypertension, anterior wall infarction, Killip class, and SCr were identified as risk factors for these outcomes.

Objective To analyze the infection status and epidemic trends of soil-borne nematode infections in Yubei, Chongqing City, in 2010,2021, and 2022. Methods The local populations from four survey sites of four towns in 2010 and five sites of five towns in 2021 and 2022 were surveyed regarding their basic information using a unified form. Fecal samples of the participants were collected and tested for soil-borne nematode infections using the modified Kato-Katz thick smear method. Results In 2010, 2 049 participants were surveyed, followed by 1 000 participants in 2021 and 2022. The overall prevalence of parasitic infections declined significantly from 3.86% to 0.20%. In 2010, soil-transmitted nematode included hookworms(3.81%) and roundworms(0.29%). In 2021, the infection rates of roundworms and hookworms were 1.70% and 0.10% respectively. Notably, only Ascaris was identified in 2022(0.20%). The≥60 age group consistently exhibited the highest infection rates across all surveys, followed by the 40-59 age group. The infection rates of males in the three surveys were 3.31%,1.92%, and 0.20% respectively, and those of females were 4.37%, 1.46%, and 0.20% respectively. There was no statistically significant difference in the infection rates between males and females. Educational attainment was inversely associated with infection; in 2010, the highest prevalence was observed among those with primary education or below, whereas in 2021, illiterate or semi-literate individuals showed the highest susceptibility. The occupational distribution of infections in 2010 indicated that retirees (8.33%), farmers(4.86%), and homemakers or unemployed individuals(3.45%)were the most affected. However, in 2021 and 2022, farmers emerged as the predominant occupational group with soil-transmitted nematode infections. Conclusions The infection rate of soil-borne nematodes showed a decreasing trend in Yubei, and the infection species changed from hookworms in 2010 to Ascaris in 2022. Farmers, the elderly, and people with low education levels should continue to be the focus of preventive and control efforts.

Aim To examine the pathogenesis of disul-fide death gene in vascular dementia(VD)by bioin-formatics analysis of disulfide death differentially ex-pressed genes(DEGs)combined with experimental verification.Methods The death DEGs of disulfide were screened and their correlation was analyzed.The VD patients data in the data set were analyzed by clus-tering and typing and gene set variation.The clustering risk of DEGs was tested with a nomogram model,and the optimal learning model was predicted.After the es-tablishment of VD rat model,water maze test,HE stai-ning and RT-qPCR detection were performed to verify the results of health information.Results Four DEGs including SLC7A11 were obtained,which had antago-nistic or synergistic interaction with each other.The genetic data could be divided into two subtypes with significant differences.After typing,VD disulfide DEGs were mainly concentrated in GnRH signaling pathways.The accuracy of the nomogram prediction model was high.Generalized linear was the best ma-chine learning model.Compared with the sham opera-tion group,the escape latency of rats in the model group was prolonged,the number of crossing platforms decreased,the relative mRNA expression levels of Slc3a2 and Slc7a11 decreased,and LRPPRC in-creased.Conclusions SLC7A11 and other disulfide death DEGs and its related GnRH signaling pathway may be an important part of the pathogenesis of VD di-sulfide death.SLC3A2,LRPPRC and SLC7A11 can be used as characteristic genes in the regulation of VD by disulfide death,which may affect VD progression through the regulation of disulfide death.

Objective:To analyze the changes and significance in clinical cardiac indicators of early cardiac myocardial dysfunction and cardiac substructure dose during conventional radiotherapy for N 2-N 3 non-small cell lung cancer (NSCLC) with mediastinal lymph node metastases. Methods:The data of 34 NSCLC patients with lymph node metastases in regions 4-8 admitted to the Affiliated Cancer Hospital of Guizhou Medical University from June 2022 to August 2023 were observed and analyzed. All patients were treated with volumetric modulated arc therapy with a prescribed dose of 60-70 Gy. Cardiac troponin T (cTnT) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) were measured at 6 time points: within 1 week before radiotherapy ( t0); when the cumulative radiotherapy dose reaches 20 Gy ( t20), 40 Gy ( t40), 60 Gy ( t60) during radiotherapy; within 1 week after radiotherapy ( tp); 1 month after radiotherapy( tp1). Left ventricular global longitudinal strain (LVGLS) and left atrial global longitudinal strain (LAGLS) were assessed at 4 time points: t0, t40, tp and tp1, respectively. The changes in cardiac indicators at different time points during radiotherapy and their correlation with substructure doses were analyzed using analysis of variance, linear regression analysis, and Pearson correlation. Results:The correlation between cardiac substructure dose and mean heart dose (MHD) in the study cohort in the descending order was as follows: left ventricle ( B=0.43, P<0.001), right ventricle ( B=0.37, P=0.002), left atrium ( B=0.16, P<0.001), and right atrium ( B=0.15, P=0.001). There were significant differences in the changes of LVGLS and LAGLS across different time points ( F=3.13, P=0.029; F=17.18, P<0.001). At 1 month after radiation, LAGLS was significantly decreased compared to pre-radiation levels ( P=0.009), whereas no significant difference was observed in LVGLS ( P=1.000). No significant differences were observed in the changes of cTnT and NT-proBNP across different time points (all P>0.05). Significant correlations were identified between cTnT and right ventricle mean dose at t40 ( r=0.38, P=0.025), as well as between NT-proBNP and right atrium mean dose at t60 and tp ( r=0.54, P=0.001; r=0.41, P=0.016). Conclusions:At present, there is no significant difference between the sensitive serum markers of myocardial injury and LVGLS in detecting early myocardial injury. LAGLS may hold substantial clinical value. There is uncertainty about radiation injury and repair of various cardiac substructures.

Objective:To analyze the dynamic changes of serum exosome miR-552 and miR-653 levels in pa-tients with gastric cancer before and after chemotherapy and their relationship with clinical benefit.Methods:IA total of 128 patients with gastric cancer received chemotherapy from January 2022 to January 2024.According to the chemo-therapy effect,the two groups were divided into disease progression group and disease remission group.The levels of serum exosome miR-552 and miR-653 before and after chemotherapy were detected in the two groups,the risk fac-tors affecting the chemotherapy effect of gastric cancer patients were screened,the risk nomogram model was con-structed,and the efficacy was evaluated.Results:The proportion of TNM stage(Ⅲ+Ⅳ),lymph node metastasis,dis-tant metastasis,tumor size(>5 cm),invasion depth(T3/T4)and tumor growth pattern(invasive type)in disease progres-sion group was higher than that in disease remission group(P<0.05).The levels of serum exosomes miR-552 and miR-653 in disease progression group were higher than those in remission group before and after chemotherapy(P<0.05).Compared with before chemotherapy,miR-552 and miR-653 levels in both groups decreased(P<0.05).Logistic regres-sion analysis showed that TNM stage,lymph node metastasis,distant metastasis,tumor size,invasion depth,miR-552 and miR-653 were all risk factors affecting the chemotherapy efficacy of gastric cancer(P<0.05).ROC curve results showed that the AUC,95%CI,sensitivity and specificity of risk nomogram model to predict chemotherapy efficacy of gastric cancer were 0.867,0.672～0.991,92.80%and 80.40%,respectively(P<0.001).Calibration curve results showed that both predicted and actual predicted values were near the ideal curve,and the Hosmer-Lemeshow goodness of fit curve test χ2=1.869,P=0.782.Conclusion:The levels of serum exosomes miR-552 and miR-653 are closely related to the chemotherapy efficacy of gastric cancer,and dynamic monitoring of the above indexes is helpful for the evaluation of the disease and prognosis of gastric cancer.In this study,the risk nomogram model constructed based on the above indexes and other risk factors has high predictive value and clinical practicability for chemotherapy efficacy in patients with gastric cancer.

Objective:To investigate the association of the interaction and combined effect of renal function and body mass index (BMI) with the risk for all-cause death in patients with type 2 diabetes mellitus (T2DM) in communities of Jiangsu Province.Methods:The study subjects were from the Comprehensive Research Project of Diabetes Prevention and Control conducted in Jiangsu from December 2013 to January 2014, and follow up was conducted for them until September 30, 2023. A total of 20 025 subjects were included in the study. Cox proportional hazards regression model was used to analyze the association of renal function with risk for death in T2DM patients, and the association of interaction between renal function and BMI and their combined effect with all-cause death risk in T2DM patients.Results:In the follow up for 198 370 person-years, a total of 4 459 deaths were recorded. Cox proportional hazards regression model analysis showed that renal dysfunction was associated with 71% risk of all-cause mortality in all T2DM patients [hazard ratio ( HR) =1.71, 95% CI: 1.59-1.84], as well as in all BMI subgroups. Likelihood ratio test indicated an interaction between renal function and BMI (interaction for P=0.030). Compared with patients with normal renal function and normal BMI, those with normal renal function and over weight or obesity had a lower risk of all-cause mortality, and those with renal dysfunction and low weight had the highest risk for death ( HR=2.78, 95% CI: 1.87-4.14). Conclusions:There is association of interaction between renal function and BMI with all-cause mortality in T2DM patients. T2DM patients with renal dysfunction and low body weight had significant higher risk for death.

Objective:To investigate the efficacy of oral folic acid intervention in lung cancer patients with radiation esophagitis (RE) caused by concurrent chemoradiotherapy.Methods:In this randomized, controlled, single-center clinical trial, a total of 82 patients with stage N 2-N 3 lung cancer including small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) admitted to the Affiliated Cancer Hospital of Guizhou Medical University from June 2022 to October 2023 were prospectively included. All enrolled patients were randomly divided into the experimental group (folic acid group) and control group according to 1 vs. 1 of simple random method, and patients in both groups were required to receive radiation therapy for lung lesions and mediastinal metastatic lymph nodes [≥2 cycles of chemotherapy were completed during the same period of radiotherapy (≥40 Gy / 20 F) or targeted drugs were given simultaneously]. The severity of RE was evaluated using the modified common terminology criteria for adverse events criteria of the National Cancer Institute in both groups weekly at the onset of radiation esophagitis symptoms and thereafter until 1 week after the end of radiotherapy. Conventional treatment of RE was delivered according to the grading criteria of the Radiation Therapy Oncology Group. Patients in the folic acid group were given with folic acid tablets 30 mg/d orally at the beginning of radiotherapy until the end of radiotherapy, while those in the control group did not receive any drug intervention. The onset time, severity and duration of RE, and changes in the severity of esophageal toxicity after conventional treatment were recorded and analyzed. Serum folate value, serum vitamin B 12 value and homocysteine value were measured before and after radiotherapy. For continuous quantitative variables, independent sample t-test or independent sample rank-sum test was used for comparison among different groups. For categorical data, Chi-square test or Fisher's exact probability method was used for comparison among different groups. Results:During the observation period, no grade 4 or above RE was reported between two groups. The incidence of grade 0, 1, 2 and 3 RE in the folic acid and control groups was 10% (4/40) and 5% (2/41), 70% (28/40) and 42% (17/41), 15% (6/40) and 51% (21/41), 5% (2/40) and 2% (1/41), respectively. The differences were not statistically significant between two groups ( P=0.456). However, the incidence of grade 0-1 RE in the folic acid group was significantly higher than that in the control group ( Z=2.72, P=0.006). The median time of RE in the folic acid group and control group was 12 d (range 7-52 d) and 15 d (range 11-56 d) after the start of radiotherapy, respectively, with no statistically significant difference ( χ2=-0.75, P=0.456). However, median duration of the individual's most severe RE was 12 d (range 4-36 d) and 21 d (range 7-38 d) in the folic acid group and control groups, respectively, and the differences were statistically significant ( χ2=2.10, P=0.039). In the folic acid group, the grades of swallowing with pain and dysphagia were significantly declined after folic acid intervention, especially at 2 weeks after the occurrence of RE ( P=0.001, P=0.002). The remission rate of RE after 1 week in the folic acid group was higher than that in the control group, and the difference was statistically significant ( χ2=7.36, P=0.012). Conclusion:Oral intake of folic acid during concurrent chemoradiotherapy for lung cancer cannot reduce the incidence of RE, but it may reduce its severity, shorten the duration of the most severe RE in individuals, and have a certain protective effect.

Objective:To construct and evaluate the predictive performance of a multiphase ultrasound radiomics model for microvascular invasion（MVI）in hepatocellular carcinoma（HCC）.Methods:A total of 126 patients with pathologically confirmed HCC were retrospectively enrolled from 4 medical centers between May 2018 and July 2025，including the First Hospital of Shanxi Medical University，Shanxi Province Third People's Hospital，Changzhi People's Hospital，and the Organ Transplant Center of the Affiliated Hospital of Qingdao University. A total of 630 ultrasound images of the lesions in different phases were collected，from which 1 561 radiomic features were extracted. The patients from medical institutions in Shanxi Province were chosen as the training set（ n=91），and the patients from the Organ Transplant Center of the Affiliated Hospital of Qingdao University were chosen as the validation set（ n=35）. In the training set，37.4%（34/91）patients presented MVI（+），whereas in the validation set，54.3%（19/35）patients presented MVI（+）. Radiomics features were extracted from ultrasound images，and features related to the MVI（+）were selected through dimensionality reduction analysis. Five multiple machine learning algorithms were used to construct predictive models，which were then evaluated using an external validation set. The Radscore was calculated，and a nomogram was constructed combining Radscore with ultrasound and clinical characteristics to predict MVI. Results:The model combining radiomics features from the portal venous phase and the delay phase showed the best predictive performance in both the training and validation sets，with area under curve（AUC）values of 0.835 and 0.727，respectively. The prediction model developed using radiomics Radscore and clinical indicators could be represented and presented as a nomogram.Conclusions:The radiomics model based on multi-phase ultrasound offers a novel approach for non-invasive preoperative prediction of MVI in liver cancer. Furthermore，its integration with clinical features aids in optimizing clinical treatment strategies.

Based on network pharmacology,molecular docking,and experimental validation,this study explored the mechanism by which Hypericum japonicum Thunb-Prunella vulgaris treat liver injury.Mice were randomly divided into four groups:a control group(CON),a model group(CCl4),a high-dose drug group(TXD-H),and a low-dose drug group(TXD-L).A mouse liver in-jury model was established using CCl4 induction.The pathological morphology of liver tissue was observed,and the serum levels of aspartate aminotransferase(AST)and alanine aminotransferase(ALT)were measured.Active ingredients of traditional Chinese medicine and targets related to these medicines and diseases were obtained from databases such as TCMSP,PubChem,Swiss Tar-get Prediction,GeneCards,and DisGeNET.The intersection of these targets was used to identify potential drug targets.A network diagram illustrating the relationships between"drug-active com-ponent-intersection target"was constructed using Cytoscape.Potential targets were analyzed using the STRING database for protein-protein interaction(PPI)analysis and the DAVID database for Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analysis.Molecular docking validation was performed using AutoDock Tools software.Subsequently,key target genes,including those related to the NLRP3 inflammasome and pyroptosis,were detected to validate the molecular docking results.Animal experimental results showed that compared to the CON group,serum AST and ALT activities in the CCl4 group mice were significantly increased(P＜0.01),while in the TXD-L group,serum AST and ALT activities were significantly decreased(P＜0.05)compared to the CCl4 group,and in the TXD-H group,AST and ALT activities were significantly decreased(P＜0.01).Through network pharmacology,135 potential targets were i-dentified,with key components found to be tetramethoxyluteolin,quercetin,kaempferol,luteolin and morin based on degree values,and key targets including TNF,SRC,AKT1,EGFR and ESR1.GO enrichment analysis yielded 304 entries,while KEGG enrichment analysis identified 91 biologi-cal pathways.Molecular docking results demonstrated strong binding between the main compo-nents of Hypericum japonicurn Thunb-Prunella vulgaris and key targets.qPCR results showed that compared to the CON group,the CCl4 group exhibited upregulated relative expression levels of SRC,EGFR,TNF-α,AKT1,and IL-18 mRNA,with significant increases in MyD88,NF-κB,IL-1β,NLRP3,Caspase-1,and ASC mRNA(P＜0.05),and significant upregulation of TLR4 and GS-DMD mRNA(P＜0.01).Compared to the CCl4 group,the TXD-H group displayed significant downregulation of EGFR,AKT1,TLR4,IL-1β,and GSDMD mRNA(P＜0.01),significant decrea-ses in TNF-α,MyD88,NF-κB,NLRP3,and ASC mRNA(P＜0.05),while SRC,IL-18,and Caspase-1 mRNA showed a downward trend.In conclusion,Hypericum japonicum Thunb-Prunel-la vulgaris exerts hepatoprotective effects through multiple components and pathways,among which inhibition of the NF-κB-NLRP3 pathway to reduce hepatocyte pyroptosis may be one of the important pathways for its protective effects.
