Objective To analyze the distribution of pathogens and the epidemiological characteristics of children with acute lower respiratory tract infections (ALRTI) admitted to Zhengzhou People’s Hospital from February 2024 to February 2026. Methods: A total of 193 pediatric patients with ALRTI who visited Zhengzhou People’s Hospital between February 2024 and February 2026 were selected as study subjects. Throat swab samples were collected from the patients, and pathogen testing results were compiled to compare the distribution of pathogens across different genders, age groups, and seasons of onset. Results: Among the 193 children, 165 tested positive for pathogens, resulting in an overall positive detection rate of 85.49%. The top three most frequently detected pathogens were RSV (20.73%), MP (19.69%), and HRV (15.54%); RSV infection had the highest prevalence (44.83%) among infants, followed by HRV infection (20.69%). Among preschoolers, the prevalence of RSV, HRV, and MP infections (17.31%, 17.31%, and 19.23%, respectively) was relatively high. MP infections were most common among preschool and school-age children (33.33% and 26.32%, respectively); the proportion of mixed infections was lower among infants (6.90%) but higher among preschoolers (20.00%); In spring, the distribution of pathogens was relatively balanced, with high proportions of HRV, MP, and SP infections (14.58%, 12.50%, and 14.58%, respectively). In summer and fall, the MP infection rate was high (31.82% and 28.85%, respectively). In winter, the RSV infection rate (55.10%) was high. The proportion of children with mixed infections was relatively similar across the four seasons, with a relatively higher infection rate (17.31%) in autumn. Conclusion: Among the pathogens identified in children with acute lower respiratory tract infections admitted to Zhengzhou People’s Hospital from 2024 to 2026, RSV and MP were the primary pathogens. The incidence peaks of various respiratory pathogens varied according to the children’s age groups and seasons. Clinicians should conduct early pathogen identification based on actual conditions to guide the development of targeted treatment plans and improve patient outcomes.

       1型糖尿病（T1DM）是一种免疫介导的胰岛β细胞特异性破坏的自身免疫性疾病，全球发病率逐年上升。胰岛自身抗体（IAbs）是T1DM最可靠的生物标志物，用于早期预测和诊断。然而，传统的放射配体法（RBA）虽然具有高实验特异度，但在疾病特异度方面存在局限性，尤其是单抗体阳性的预测价值较低。近年来，电化学发光法（ECL）作为一种无放射性污染的新方法，能够区分高亲和力和低亲和力的IAbs，显著提高了疾病特异度。多项研究表明，ECL法在预测T1DM风险方面优于RBA法，特别是在单抗体阳性的情况下。本文综述了IAbs检测方法的进展及其在T1DM预测和诊断中的应用，强调了ECL法在提高疾病特异度方面的优势。
