Abstract: Hypoxia-inducible factor 1? protein or a detection reagent thereof can be used in depression recurrence diagnosis. It has been demonstrated that the specificity of hypoxia inducible factor 1? protein increases in the serum of patients with depression recurrence after interventions. As such, hypoxia inducible factor 1? protein can be used as a peripheral blood biomarker for the early screening or differentia diagnosis of depression recurrence, and for post-intervention assessment of treatment efficacy of patients with depression.
