ABSTRACT

Objective To explore the significance of serum cytokine interferon-gamma (IFN-γ) ,interleukin-4(IL ) ,transforming growth factor-beta 1 (TGF-β1) ,interleukin-9 (IL-9) ,interleukin-17 (IL-17) in detection of youth first-episode depression .Methods Ninety cases of youth first-episode depression as the experimental group were equally divided into 3 groups according to different disease courses(2 years)and other 30 normal persons served as the control group .The levels of serum cytokines were measured by ELISA .The level of each cytokine and Hamilton Depression Scale (HAMD) score were per-formed the Spearman correlation analysis .Results The IL-9 level in the 6 months to 2 years group and > 2 years group was high-er than that in the control group (P2 years group(P<0 .05);the IL-4 level was positively correlated with the depressive mood (P<0 .05) .Conclusion Different cytokines play different roles in youth first-episode depres-sion ,cytokines may involve in the occurrence and development of depression .
