Abstract:
Objective To explore the change in heme oxygenase-1 (HO-1) level in cerebrospinal fluid(CSF)and serum in patients with mild cognitive impairment(MCI),and the correlation between HO-1 and the rating scale,to provide a new marker for the diagnosis of MCI.Methods The HO-1 levels in CSF and serum in 45 MCI patients (MCI group) and 85 normal cases (control group) were analyzed with sensitive enzyme linked immunosorbent assays (ELISA).MMSE and MoCA scores were evaluated.Results The level of HO-1 was higher in MCI group than in control group both in CSF [(631.38±32.17)vs(480.75±17.98)ng/ L,P＜0.05],and in serum [(612.52±111.48)vs.(384.16±56.86)ng/ L,P＜0.05].The MCI and normal people HO-1 level had no significant difference between CSF group and serum group (P＞0.05).In MCI group,the levels of serum and CSF HO-1 had a positive correlation with MMSE scores (P＜0.05),but had no obvious correlation with MoCA scores (P＞0.05).In the normal group,the level of HO-1 was negatively related with MMSE scores in serum and CSF,and with MoCA scores in CSF (P＜0.05),but no obvious correlation in serum (P＞0.05).The levels of serum and CSF HO-1 had no obvious correlation with age in both groups (P＞0.05).Conclusions HO-1 concentration in both CSF and serum is significantly higher in MCI group than in normal group,and positively related with MMSE score.Thus the increase of HO-1concentration in both CSF and/or serum might be a new marker for the diagnosis of MCI.
