Abstract:

Objective To investigate the correlation between serum thioredoxin 2(Trx2),phosphorylated tau(P-tau) and total magnetic resonance imaging(MRI) load score and cognitive function in patients with cerebral small vessel disease. Methods Totally,94 patients with cerebral small vessel disease in Cangzhou Central Hospital from July 2019 to July 2020 were enrolled. According to whether they had cognitive function impairment,the patients were classified into cognitive impairment group(38 cases) and non-cognitive impairment group(56 cases). According to the total MRI load score,the patients were classified into mild load group(67 cases) and moderate to severe load group(27 cases). The general data and clinical laboratory determination results were collected. Serum Trx2 and P-tau were determined,and the factors for total MRI load and cognitive function in patients with cerebral small vessel disease was analyzed by multivariant Logistic regression analysis. Pearson correlation analysis was used to evaluate the correlation between each indicator and total MRI load and cognitive function. Results There was statistical significance in sex,age,drinking history,smoking history,high-density lipoprotein cholesterol(HDL-C),uric acid(UA),total MRI load score,Trx2 and P-tau levels between cognitive impairment group and non-cognitive impairment group(P<0.05),and there was no statistical significance in the other indicators(P>0.05). There was statistical significance in sex,age,hypertension history,HDL-C,UA,Trx2 and P-tau levels between mild load group and moderate to severe load group(P<0.05),and there was no statistical significance in the other indicators(P>0.05). Serum Trx2 [odds ratio(OR)=2.751,95% confidence interval(CI) 1.123-6.738] and serum P-tau(OR=2.651,95%CI 1.180-5.956) were independent risk factors for cognitive function impairment in patients with cerebral small vessel disease(P<0.05). Serum Trx2 and P-tau were positively correlated with total MRI load score and CMMSE score in patients with cerebral small vessel disease(P<0.05). Conclusions Serum Trx2 and P-tau are related to total MRI load and cognitive function in patients with cerebral small vessel disease,which can be used to evaluate the severity and cognitive function of cerebral small vessel disease.
