Abstract:
Objective:To investigate the correlation between cognitive impairment and blood glucose, serum neuron specific enolase (NSE) and brain-derived neurotrophic factor (BDNF) levels after ischemic small-artery stroke.Methods:A total of 160 patients with ischemic small-artery stroke who received treatment in Jincheng People's Hospital from January 2018 to December 2019 were included in this study. They were divided into an observation group (with cognitive impairment, n = 68) and a control group (without cognitive impairment, n = 92) according to whether they had cognitive impairment. General data, blood glucose, NSE and BDNF levels were compared between the two groups. Multivariate logistic regression analysis was used to analyze the correlation between cognitive impairment and each factor after ischemic small-artery stroke. Results:There were no significant differences in gender, age, course of disease, body mass index, history of hypertension, hyperlipidemia, history of type 2 diabetes mellitus, history of smoking, and history of drinking between the two groups (all P > 0.05). The National Institute Health of Stroke Scale (NIHSS) score in the observation group was significantly higher than that in the control group [(18.86 ± 4.08) points vs. (14.27 ± 2.66) points, t = 6.664, P < 0.05], and the Mini-Mental State Examination (MMSE) score in the observation group was significantly lower than that in the control group [(21.45 ± 3.03) points vs. (24.28 ± 3.32) points, t = 4.452, P < 0.05]. There were no significant differences in glycosylated hemoglobin, fasting blood glucose, high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triglyceride (TG) and total cholesterol levels between the two groups (all P > 0.05). There were significant differences in oxidized low-density lipoprotein (ox-LDL), NSE and BDNF levels between the two groups. The ox-LDL [(44.8 ± 7.6) mmol/L] and NSE [(26.5 ± 9.5) ng/mL] levels in the observation group were significantly higher than those in the control group [(35.9 ± 4.7) mmol/L, (11.6 ± 6.9) ng/mL, t = 7.04, 8.973, both P < 0.05]. BDNF level in the observation group was significantly lower than that in the control group [(5.1 ± 1.8) ng/mL vs. (6.3 ± 2.4) ng/mL, t = 2.828, P < 0.05]. Multivariate logistic regression analysis showed that ox-LDL and NSE levels and NIHSS score were independent risk factors of cognitive impairment after ischemic small-artery stroke (all P < 0.05), and BDNF level and MMSE score were independent protective factors (all P < 0.05). Conclusion:Cognitive impairment was correlated with NIHSS score, MMSE score, ox-LDL, NSE and BDNF levels in patients with ischemic small-artery stroke. ox-LDL and NSE levels as well as NIHSS score were independent risk factors and BDNF level and MMSE score were independent protective factors of ischemic small-artery stroke.
