Purpose: To investigate the correlation between plasma levels of high mobility group protein N1 (HMGN1) and the severity of neurological deficits and prognosis in patients with acute cerebral infarction (ACI).
Patients and Methods: The plasma HMGN1 levels of 108 patients with ACI were detected by ELISA. The National Institutes of Health Stroke Scale (NIHSS) and the modified Rankin Scale (mRS) were used to assess the neurological impairment and outcomes of these patients, respectively. The correlation between HMGN1 levels and clinical parameters was analyzed.
Results: The plasma HMGN1 levels of patients with ACI were positively correlated with their NIHSS and mRS scores. Patients with the large artery atherosclerosis (LAA) subtype in the Trial of Org 10172 in Acute Stroke Treatment (TOAST) classification had higher plasma HMGN1 levels than patients with other subtypes.
Conclusion: HMGN1 levels are positively correlated with the severity of ACI and could be used to predict the prognosis of these patients. HMGN1 can be used as a biological marker and potential target for clinical assessment and therapy of ACI.
