To investigate the distribution of common inhalant and food allergens test results in children in Suzhou by gender, age and disease group, and to analyse the changes in allergen distribution in the different years, to provide theoretical guidance for the diagnosis, treatment and monitoring of children′s allergic diseases in Suzhou City. A retrospective cross-sectional study was conducted to analyze the 2 736 children (1 654 males and 1 082 females) who were diagnosed and tested serum content of specific immunoglobulin E (sIgE) antibodies to inhalant and food allergens in the Children′s Hospital of Soochow University between October 2017 and June 2024. The allergen sIgE positive rates epidemiological characteristics were statistically analyzed by Chi square test by grouping based on different year, gender, age and disease. The results showed that a total of 2 736 children screened for allergens, with an overall positive allergen sIgE rate of 73.06%(1 999/2 736), and the top five allergen sIgE positive rates were Dermatophagoides farinae (40.75%, 1 115/2 736), Dermatophagoides pteronyssinus (38.78%, 1 061/2 736), milk (34.65%, 948/2 736), egg whites (32.68%, 894/2 736) and molds and yeasts mixes (mx2) (24.82%, 679/2 736). The positive rates of food allergen sIgE were higher in the 2017-2019 (60.46%, 370/612) than the 2020-2022 (53.79%, 149/227) and after the 2023-2024 (48.46%, 895/1 847) ( χ2=27.059, P<0.001); The positive rates of inhaled allergen sIgE were lower in the 2017-2019 (40.03%, 245/612) than the 2020-2022 (52.71%, 146/227) and the 2023-2024 (56.04%, 1 035/1 847)( χ2=47.223, P<0.001). The positive rates of inhaled allergen sIgE in males (54.96%, 909/1 654) were higher than those in females (47.78%, 517/1 082) ( χ2=13.497, P<0.001). The total positive rate for the food allergen sIgE was highest at 1-3 years of age (67.55%, 589/872) and then gradually decreased with age ( χ2=194.095, P<0.001); The total positive rate of inhaled allergen sIgE was lowest at the age of less than 1 year (8.33%, 22/206) and then gradually increased with age ( χ2=300.329, P<0.001). The positive rates of food allergen sIgE, in descending order from high to low were asthma (59.40%), atopic dermatitis and eczema (48.10%), other groups (48.02%), allergic rhinitis (45.73%) and urticaria (40.00%); The positive rates of inhaled allergen sIgE were asthma (71.05%), allergic rhinitis (63.57%), atopic dermatitis and eczema (62.17%), urticaria (40.00%) and other groups (49.76%), and the difference between disease subgroups were statistically significant( χ2 were 64.841 and 19.055, P<0.05). In conclusion, the top four allergen sIgE positive rates for children in the Suzhou area were Dermatophagoides farinae, Dermatophagoides pteronyssinus, milk and egg white. Total sIgE positive rates for food allergens decreased progressively in the 2017-2019, 2020-2022 and 2023-2024, and total positive rates for inhalant allergens increased progressively in the 2017-2019, 2020-2022 and 2023-2024. The distribution of allergen positive varies with gender, age and disease.

Objective:To investigate the role of aging-related genes(ARGs)in the prognosis of lung squamous cell carcinoma(LUSC)and establish a novel prognostic prediction model.Methods:Transcriptomic data and clinical information of LUSC patients were obtained from TCGA,combined with ARGs from Aging Atlas.Key genes were screened through differential expression analysis,survival analysis,and Cox regression to construct a prognostic model.Model performance was validated in clinical subgroups,and biological pathway enrichment(GSEA)and immune microenvironment analyses were performed.Results:Five ARGs(ERFFI1,MDH1,SENP2,SNAI1,TP63)were identified to build the model.Significant survival differences were observed between high-and low-risk groups(P＜0.001),with 1-,3-,and 5-year AUC values of 0.610,0.668,and 0.665,respectively.The risk score was an independent prognostic factor(HR=11.261,95％CI:3.654-34.701,P＜0.001)and showed predictive efficacy in both early-stage(Ⅰ-Ⅱ,P=0.022)and advanced-stage(Ⅲ-Ⅳ,P=0.004)patients.GSEA revealed significant enrichment of Alzheimer's disease(P=0.003)and cell adhesion pathways(P=0.008)in high-risk groups.SNAI1 correlated positively with M1/M2 macrophage infiltration(r=0.45,P＜0.001),MDH1 associated with 12 immune cell types(|r|＞0.3,P＜0.05),and the risk score linked to CD8+T cells(r=0.38)and M2 macrophages(r=0.32)(both P＜0.001).Twenty-three immune checkpoints(e.g.,TNFRSF14,CD200R1)were differentially expressed between groups and survival-related(P＜0.05).High-risk patients exhibited elevated TIDE scores(P＜0.001),indicating enhanced immune suppression.Conclusion:This model provides a novel tool for LUSC prognosis assessment,but further clinical validation is required.

Objective:To explore the role and possible mechanism of ACOT11 in renal fibrosis model mice.Methods:A mouse model of renal fibrosis was established by unilateral ureteral obstruction(UUO)(Sham group and UUO7 group),and the expression of ACOT11 in the kidneys of UUO induced fibrosis mouse models was detected by protein immunoblotting and real-time fluorescence quantitative PCR(qRT-PCR).Subsequently,immunohistochemistry,Masson staining,H&E staining,PAS staining,and other experimental methods were used to detect the expression levels of fibrosis biomarkers fibronectin,α-SMA,and COL-1 in the kidneys of control and experimental group mice.In addition,by constructing ACOT11 gene knockout model mice and using the gene knockout model mice to construct a renal fibrosis model,the expression levels of fibrosis biomarkers such as fibronectin,α-SMA,COL-1,as well as fibrosis mechanism pathway related indicators TGF-β and Smad2 in the kidneys of each group of mice were further detected.Results:The results of WB and qRT-PCR experiments showed that the expression of ACOT11 in the kidney tissue of UUO model mice was significantly reduced compared to the Sham group.After knocking out the ACOT11 gene,H&E staining,PAS staining,and Masson staining showed that pathological inflammatory reactions such as abnormal glomerular and tubular structures,inflammatory cell infiltration and interstitial fibrous tissue proliferation in mice were significantly aggravated compared to the control group,and the expression of fibrosis markers Fibronectin,α-SMA,and COL-1 was significantly higher than that of the control group.Conclusion:ACOT11 plays a protective role in mice with unilateral ureteral obstruction model.After ACOT11 gene knockout,the fibrosis biomarkers of the mouse kidney increases and the degree of fibrosis worsens.
