A total of 115 patients with COPD who were admitted to our hospital from August 2022 to October 2025 were selected as the research subjects. Based on the Hospital Anxiety and Depression Scale (HADS), the patients were divided into the asymptomatic group (HADS anxiety score \u2264 7 points), the mild group (8\u201310 points), and the moderate-to-severe group (&amp;gt; 10 points). Serum levels of Gal-3, Th1 cytokines (IL-2 and IFN-\u03b3), and Th2 cytokines (IL-4 and IL-33) were quantified. Pearson correlation analysis was used to examine the relationship. Logistic regression model was employed to analyze the influencing factors. Receiver operating characteristic curve (ROC) was used to evaluate the diagnostic value of serum Gal-3 and Th1\/Th2.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Serum levels of Gal-3, IL-2, IFN-\u03b3, IL-4, and IL-33 were increased significantly in correlation with symptom severity, with the highest levels observed in the moderate-to-severe group (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0&amp;lt;\u00a00.05).

The combined detection model achieved a superior AUC of 0.905 (95% CI: 0.845\u20130.965) for identifying moderate-to-severe anxiety and depression symptoms. This combined model demonstrated a sensitivity of 85.51% and a specificity of 86.96%, significantly outperforming the single-marker.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Gal-3 was synergistic with Th1\/Th2-related cytokines and was associated with the severity of anxiety and depression symptoms in patients with COPD.
