Objective To explore the potential causal relationship between occupational pneumoconiosis (hereinafter referred to as "pneumoconiosis") and five mental disorders (depression, bipolar disorder, schizophrenia, insomnia and anxiety) using the two-sample Mendelian randomization (MR) method. Methods Single nucleotide polymorphisms (SNPs) loci associated with pneumoconiosis and five mental disorders were screened from Genome-Wide Association Studies. Inverse variance weighting (IVW), weighted median (WM) and MR-Egger regression methods were used to evaluate the significance of the causal relationship between pneumoconiosis and five mental disorders. Sensitivity analysis was used to evaluate the accuracy and reliability of the research results. Results After matching data of pneumoconiosis and the five mental disorders, 16 SNPs were ultimately included as instrumental variables in this study. The result of MR analysis revealed a positive causal relationship between pneumoconiosis and both depression [IVW: odds ratio (OR) and 95% confidence interval (CI) was 1.017 (1.000-1.035), P<0.05] and bipolar disorder [IVW: OR(95%CI)was 1.046(1.009-1.083), P<0.05; WM: OR (95%CI) was 1.055(1.007-1.105), P<0.05]. Result of sensitivity analysis indicated there was no heterogeneity and horizontal pleiotropy in the above results. There was no causal association observed between pneumoconiosis and schizophrenia, insomnia, or anxiety disorders (all P>0.05). Conclusion This study provides genetic evidence supporting a positive causal relationship between pneumoconiosis and both depression and bipolar disorder.

Objective To develop a risk assessment scale for immune checkpoint inhibitor (ICI)-associated myocarditis based on multidisciplinary collaboration, and to evaluate its diagnostic performance. Methods Based on multidisciplinary cooperation, integrating clinical experience from oncology and cardiology, literature data, and patient conditions, a risk assessment scale for ICI-associated myocarditis was developed. A total of 101 patients with malignancies who received immunotherapy at Zhongshan Hospital, Fudan University, from October 2020 to October 2024 were included as the validation cohort. Patients were stratified into low-risk (0-1 point), medium-risk (2-4 points), and high-risk (≥5 points) groups based on their scale scores. The association between pretictive risk stratifications and actual assessment results was assessed using the Cox proportional hazards regression model. The predictive value of the scale for ICI-associated myocarditis was evaluated using receiver operating characteristic (ROC) curve. Agreement between the scale scores and actual assessment results was assessed using Cohen’s Kappa coefficient. Results Based on the scale pretictive results, 28(27.7%), 8(7.9%), 65(64.4%) patients were at low risk, medium risk, and high risk for ICI-related myocarditis, respectively; however, 46(45.5%), 8(7.9%), 47(46.5%) were at low risk, medium risk, and high risk actually. Kaplan-Meier survival analysis showed that the cumulative incidence of ICI-related myocarditis in the high-risk group was significantly higher than that in the medium- and low-risk groups (P＜0.05). In the multivariable-adjusted Cox proportional hazards model, the ICI-related myocarditis risk in high-risk group was about 4 times that in the low-risk group. ROC curve analysis demonstrated that the average area under the curve (AUC) for predicting ICI-related myocarditis was 0.81, with an accuracy of 0.74. The Cohen’s Kappa coefficient was 0.55, indicating moderate agreement. In the actual high-risk group, no patient was predicted to be at low risk; in the actual low-risk group, 16 patients were predicted to be at high risk. Conclusions This risk assessment scale for ICI-associated myocarditis shows high predictive performance. It provides oncologists with a simple yet effective multidisciplinary diagnostic reference tool, potentially enhancing early identification of ICI-associated myocarditis.

Objective To investigate the improvement effect of Necrostatin-1 (Nec-1) on mouse models with immune checkpoint inhibitor (ICI) -associated myocarditis (ICIAM) and potential mechanism. Methods Ten male BALB/c mice aged 6-8 weeks were selected to construct the ICIAM models. The echocardiography and serum myocardial injury markers were used to assess cardiac function of mice. The levels of inflammatory markers including tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) were detected by enzyme-linked immunosorbent assay (ELISA) and quantitative real-time polymerase chain reaction (qRT-PCR), respectively. Hematoxylin-eosin (HE) staining was used to evaluate myocardial inflammation, and Masson staining was used to evaluate myocardial fibrosis. The expressions of myocardial necroptosis proteins including receptor-interacting protein kinase 1 (RIP1), RIP3, mixed lineage kinase domain-like protein (MLKL) and their phosphorylated forms were detected by Western blotting. The spleen lymphocytes were extracted and co-cultured with HL-1 cell line. Cell viability was measured by cell counting kit-8 (CCK-8). The release of reactive oxygen species (ROS) and changes of mitochondrial membrane potential were observed. RIP1, RIP3, MLKL and their phosphorylated forms were determined. The levels of markers of oxidative stress, including malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), were measured. Results Nec-1 significantly improved the cardiac function injury of mice induced by ICI, and inhibited the release of TNF-α and IL-1β in plasma of ICIAM mice (P＜0.001); inhibited expressions of phosphorylated RIP1, RIP3 and MLKL (P＜0.05); decreased MDA activity, and increased SOD and GSH-Px activity (P＜0.001). In HL-1 cells, Nec-1 intervention inhibited the RIP1-RIP3-MLKL pathway (P＜0.05), improved decrease of the cell viability induced by lymphocytes (P＜0.001), decreased ROS release, increased mitochondrial membrane potential, inhibited MDA activity, and increased SOD and GSH-Px activities (P＜0.001). Conclusions Necroptosis plays an important role in the occurrence and development of ICIAM，but Nec-1 could alleviate the progression of ICIAM by inhibiting necroptosis induced by oxidative stress in cardiomyocytes; RIP1 maybe a new target in treatment of ICIAM.

Objective To investigate the effects of meropenem and amikacin on gut microbiota diversity and composition in a neonatal rat model of necrotizing enterocolitis(NEC).Methods Neonatal SD rats(1～2 d,weighing 5～10 g,both sexes)were subjected to establish a NEC model through artificial formula feeding,hypoxic-cold stress,and lipopolysaccharide(LPS)gavage.The rats were randomly divided into normal control group(Group C,n=12),NEC group(Group N,n=20),meropenem intervention group(Group M,n=20),and amikacin intervention group(Group A,n=20).Following modeling,Group M and Group A received intraperitoneal injections of meropenem(125 mg/kg)or amikacin(468 mg/kg),twice daily for 3 consecutive days.Groups C and N were administered an equal volume of normal saline.At the end of the intervention,colonic contents or fecal samples were collected.The gut microbiota structure was analyzed using 16S rDNA high-throughput sequencing.Bioinformatics analysis was performed using the QIIME2 platform.Alpha diversity was evaluated using Chao1,Shannon,and Simpson indices.Beta diversity was assessed based on Bray-Curtis distance through principal coordinate analysis(PCoA)and non-metric multidimensional scaling(NMDS).Venn and UpSet plots were generated to visualize the composition and overlap of operational taxonomic units(OTUs).Linear discriminant analysis effect size(LEfSe)was applied to identify differentially abundant taxa across groups.Results High-throughput 16S rDNA sequencing showed that the N group had significantly lower 3 indices of α diversity than the C group(P<0.01),that is,a Chao1 index from 230 to 40,a Shannon index from 1.65 to 0.85,and a Simpson index from 0.65 to 0.42.After antibiotic intervention,both the M group and A group obtained obvious increases in the Chao1 index than the N group(P<0.001),with a greater increase observed in the M group than in the A group(P<0.05).However,neither antibiotic group exhibited notable improvements in the Shannon index or Simpson index compared with the N group(P>0.05).Venn and UpSet analyses revealed that the M group had the highest number of unique OTUs(283),while the A group shared the most OTUs(63)with the C group.PCoA and NMDS analyses indicated that the microbial structure of the A group was closer to that of the C group,with better clustering.Taxonomic composition and LEfSe analysis demonstrated that the N group was enriched with potentially pathogenic taxa such as Escherichia coli B2 and Klebsiella under the phylum Proteobacteria,while beneficial bacteria including Lactobacillaceae and Bifidobacteriaceae(phylum Firmicutes)were significantly reduced,indicating severe dysbiosis.In contrast,the A group exhibited a significant increase in beneficial bacteria and a structural tendency toward ecological recovery.The M group,however,was enriched with various conditionally pathogenic and environmentally associated genera,displaying a microbial configuration notably deviating from a healthy state.Conclusion Meropenem and amikacin exhibit differential regulatory effects on the intestinal microbiota in the context of NEC.Amikacin demonstrates superior efficacy in restoring microbial stability and levels of beneficial bacteria,whereas meropenem,although effective for early infection control,warrants caution due to its potential long-term impact on the gut microbiome.

Objective:This study aimed to analyze the genomic characteristics of Varicella-Zoster Virus (VZV) strains circulating in Jilin province from 2010 to 2023.Methods:Vesicle fluid from 78 sporadic cases with VZV infection were collected in Jilin province from 2010 to 2023, after detecting by Real-time PCR, 26 specimens (CT<25) were detected by PCR. Open reading frame 22(ORF22), ORF38 and ORF62 were amplified and analyzed. Genotyping was confirmed by SNPs ORF22 (37902, 38019, 38055, 38081 and 38177) and ORF38 (69424). Vaccine strains were indentified from wild-type strains according to ORF38 (69349) and ORF62 (106262, 107252, and 108111). Sequences were analyzed by homologous comparison and phylogenetic analysis.Results:The comparison with Dumas sequence revealed that SNPs (37902, 38055, 38081 and 38177) in ORF22 and ORF38 (69424) have mutations similar to the pOka strain, which belong to clade 2. Compared to the Dumas and Baike strains, all 26 samples were wild-type strains. JL2016-4 strain changes from threonine to asparaginyl at position 38059, JL2021-4 strain changes from arginine to proline at position 37933, from aspartic acid to tyrosine at position 37935, and from aspartic acid at base 38031 to tyrosine. JL2023-1 strain changes from arginine to leucine at position 37933.Conclusions:VZV has been prevalent for 14 years in Jilin province. The main epidemic strains belong to the clade 2. We should strengthen the monitoring of VZV outbreaks and raise the coverage rate of VZV vaccination.

Immune checkpoint inhibitors(ICIs)have emerged as one of the novel immunotherapy drugs in recent years,and been approved for the treatment of multiple tumour types.However,over-activation of the immune system may lead to immune-related advese events,among these,ICIs-induced cardiotoxicity include myocarditis,pericardial disease,atherosclerosis and vasculitis.Although ICIs-induced cardiotoxicity is rare,it may lead to serious clinical complications and even death.Thus,timely identification and management of ICIs-induced cardiotoxicity is vital in clinical practice.Once diagnosed,prompt treatment is required according to the severity of the disease.Standardized prevention and treatment strategies need multidisciplinary collaboration to provide long-term individualized monitoring and management for patients.

Objective To evaluate the effects of combining immune checkpoint inhibitors,trastuzumab,and chemotherapy on the left and right ventricular function in patients with advanced gastric adenocarcinoma expressing human epidermal growth factor receptor 2(HER2).Methods 25 patients with advanced HER2-positive gastric adenocarcinoma who received HER2-ASTRUM therapy(sruili monoclonal antibody combined with trastuzumab and DOS regimen)underwent echocardiographic examinations at baseline(T1),after completion of 4 cycles(T2),and 6 cycles(T3)of chemotherapy.Left ventricular strain,left ventricular myocardial work,right ventricular strain,and ejection fraction were further analyzed.Results Compared with T1,both T2 and T3 showed a decrease in left ventricular ejection fraction(LVEF),(T1,T2,and T3 were[67.3±2.7]％,[63.0±2.9]％and[61.3±3.2]％,P＜0.05).T3 showed a decrease in right ventricular ejection fraction(RVEF),([59.3±7.8]％vs[43.7±6.6]％,P＜0.05),while T2 showed no significant change in RVEF.Both right ventricular global longitudinal strain(RVGLS),(T1,T2,and T3 were[-25.7±5.7]％,[-22.4±5.3]％and[-19.1±3.6]％,respectively;P＜0.05)and right ventricular free-wall longitudinal strain(RVFWLS),(T1,T2,and T3 were[-20.9±4.7]％,[-18.9±4.1]％and[-16.1±3.9]％,P＜0.05)decreased in all three time points.The global work index(GWI)was lower in T2 and T3 than in T1(P＜0.05),while the global constructive work(GCW),global wasted work(GWW),and global work efficiency(GWE)did not show significant changes.Conclusions Combination of trastuzumab,immune checkpoint inhibitors,and chemotherapy has an impact on left ventricular strain,LVEF,and right ventricular strain,as well as GWI,in HER2-positive patients with gastric adenocarcinoma.Left ventricular global longitudinal strain(LVGLS),RVFWLS,and RVGLS can more sensitively monitor cardiac function and detect cardiac dysfunction related to cancer treatment in a timely manner.
