Relations between serum salusin-α and lipoprotein-associated phospholipase A2 in carotid unstable plaque patients with cerebral infarction / 实用医学杂志

ABSTRACT

Objective To study the relationship between serum salusin-α and lipoprotein associated phospholipase A2(Lp-PLA2) in carotid unstable plaque with cerebral infarction. Methods One hundred patients with carotid unstable plaque confirmed by carotid ultrasound, divided into two groups as followscerebral infarction group (CI group, n = 50) or without cerebral infarction (plaque group, n = 50). We took 50 health subjects in the same period as control. The levels of serum salusin-α, Lp-PLA2 were detected by ELISA. Results Serum salusin-αlevel was significantly lower in the CI group than in the control group (P<0.01), and was also significantly lower in the CI group than in the plaque group (P < 0.01); Serum Lp-PLA2 level was obviously higher in CI group than in control group (P<0.05), and was also significantly higher in CI group than in plaque group (P < 0.05); The correlation between serum salusin-α level(OR = 0.140, 95% CI 0.054-0.368, P<0.01) and cerebral infarction was significant in patients with unstable plaque. Conclusions The decrease of serum salusin-α level is significantly in patients with unstable plaque; the increase of Lp-PLA2 is significantly in patients with unstable plaque. The serum salusin-αlevel is a possible risk factor for cerebral infarction.
