ABSTRACT
Objective:To investigate the relationship between the changes of serum lipoprotein associated phospholipase A2 (Lp-PLA2), human Parkinson′s protein 7 (PARK7), erythropoietin (EPO) and neurological deficit score (NIHSS) and carotid intima-media thickness (CIMT) in patients with acute ischemic stroke (AIS).Methods:150 patients with AIS diagnosed in our hospital from January 2016 to January 2018 (AIS group) and 80 healthy subjects were selected as the control group. The Lp-PLA2, PARK7, EPO levels were compared between the two groups according to NIHSS score (mild, moderate and severe), carotid atherosclerotic plaque (unstable plaque, stable plaque, no plaque).Results:The serum level of Lp-PLA2, PARK7, EPO and CIMT values in the AIS group were significantly higher than those in the control group ( P<0.05). The Lp-PLA2 and PARK7 levels in the mild, moderate and severe AIS patients were gradually increased among the three groups, with statistically significant difference ( P<0.05). There was no significant difference in EPO levels between the different NIHSS groups ( P>0.05); The levels of Lp-PLA2, PARK7 and EPO of AIS patients in non plaque group, stable plaque group and unstable plaque group were gradually increased among the groups, and the difference between the two groups was statistically significant ( P<0.05). The level of Lp-PLA2 and PARK7 in patients with AIS and the NIHSS scores showed a significant positive correlation ( P<0.05). There was a significant positive correlation between Lp-PLA2, PARK7, EPO and CIMT in patients with AIS ( P<0.05). Conclusions:The serum levels of Lp-PLA2, PARK7 and EPO were significantly increased in AIS patients. Lp-PLA2, PARK7 were related to the aggravation of neurological deficits in potential patients. Lp-PLA2, PARK7 and EPO were related to the increase of carotid intima-media thickness in potential patients.
