In order to find a method to monitor and treat the refractory DFU, the ferroptosis level in DFU and traumatic wounds (TW) was monitored and the difference between them was analyzed. At the same time, this study further analyzed the correlation of ferroptosis levels with DM severity and DFU\u2019s healing.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A prospective cohort study was from January, 2021 to December, 2023 in the Second People\u2019s Hospital of Gansu province, which included 59 patients with DFU and 42 patients with TW. We then used the kit to detect the indicators related to ferroptosis, including 4-Hydroxynonenal (4-HNE), Malondialdehyde (MDA) and reactive oxygen species (ROS), in the wound exudate of the two groups of patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The DFU group had higher ferroptosis level than the TW group (4-HNE: <jats:italic>P<\/jats:italic> = 0.003, MDA: <jats:italic>P<\/jats:italic>&amp;lt;0.001, ROS: <jats:italic>P<\/jats:italic>&amp;lt;0.001).

The results of multiple regression analysis showed that 4-HNE (<jats:italic>\u03b2<\/jats:italic> = -0.182, <jats:italic>P<\/jats:italic> = 0.008), MDA (<jats:italic>\u03b2<\/jats:italic> = -0.478,
