The diagnostic value and correlation of magnetic resonance parameters with TNF-α and IL-1α levels in Alzheimer's disease / 中国现代医生

ABSTRACT

Objective To explore the diagnostic value of magnetic resonance DKI parameters and serum levels of tumor necrosis factor-alpha(TNF-α)and interleukin-1α(IL-1α)in Alzheimer's disease(AD).Methods From July 2020 to July 2022,60 patients with Alzheimer's disease in our hospital were selected as the observation group and 60 healthy elderly people over 60 years old as the control group.All patients underwent routine MRI sequence examination,measured DKI parameters,and detected serum TNF-α and IL-1α levels by ELISA.Results The MD value of each brain area was significantly increased in alzheimer's disease patients.FA of white matter,hippocampus and substantia nigra decreased in temporal and parietal cortex,while FA of caudate nucleus,red nucleus and dentate nucleus increased.RK of white matter,hippocampus and thalamus in temporal and parietal cortex decreased significantly,while RK in substantia nigra increased significantly.AK of white matter,thalamus,dentate nucleus and substantia nigra in temporal and parietal cortex were significantly decreased.The MK in white matter,hippocampus and thalamus of temporal and parietal cortex decreased significantly,while the MK in caudate nucleus and substantia nigra increased significantly.The serum levels of homotype hemisoline and acetylcholinesterase increased significantly.Conclusion Combined magnetic resonance DKI parameters and detection of serum TNF-α and IL-1α levels have certain diagnostic and predictive value for the occurrence of Alzheimer's disease.
