Abstract:Objective To observe the changes and significance of lipoprotein-associated phospholipase A2 (Lp-PLA2) and oxidized low density lipoprotein (ox-LDL) in patients with acute cerebral infarction (ACI). Methods One hundred and twenty-three patients with initial ACI admitted in Taizhou Enze Medical Center (Group) Enze Hospital in Zhejiang Province from January 2015 to January 2018 were selected as the observation group, and 120 cases of healthy volunteers were selected as the control group. The levels of Lp-PLA2 and ox-LDL were detected immediately after admission and at 12, 24, 72 hours after admission. According to the severity of cerebral infarction, the patients in the observation group were divided into severe cerebral infarction group (n = 34), moderate cerebral infarction group (n = 52) and mild cerebral infarction group (n = 37). The serum levels of Lp-PLA2 and ox-LDL were compared among the three groups. According to different infarct size, the patients in the observation group were divided into large infarction group (n = 38), middle infarction group (n = 49) and small infarction group (n = 36). The changes of Lp-PLA2 and ox-LDL level were compared among the three groups. Results The serum levels of Lp-PLA2 and ox-LDL in the observation group were significantly higher than those in the control group at admission and 12, 24, 72 hours after admission, the differences were statistically significant (P < 0.05). In addition, the serum Lp-PLA2 and ox-LDL levels in the observation group increased first and then decreased with the increase of admission time. The levels of Lp-PLA2 and ox-LDL in severe cerebral infarction group were higher than those in moderate and mild cerebral infarction group (P < 0.05), and that in moderate infarction group was higher than that in mild cerebral infarction group (P < 0.05). The levels of Lp-PLA2 and ox-LDL in the large infarction group were higher than those in the middle and small infarction group (P < 0.05), and that in middle infarction group was higher than that in small infarction group (P < 0.05). Conclusion The levels of serum Lp-PLA2 and ox-LDL are significantly increased in patients with ACI, which can reflect the severity of the disease to a certain extent. They can be used as serum markers, which is of positive significance in evaluating the condition and prognosis of ACI.
