Abstract:
Objective To explore the prognostic value of serum glutathione reductase (GR)，superoxide dismutase (SOD)， cystatin C (Cys-C)，homocysteine (Hcy) and lipoprotein a [Lp(a)] levels in patients with cerebral ischemic stroke(CIS)，and to provide a reference for improving the prognosis of CIS patients. Methods 126 patients with CIS admitted to the 980th Hospital of Joint Logistics Support Force from June 2022 to April 2023 were selected as the observation group，another 126 healthy individuals were selected as the control group at a ratio of 1:1. The expression levels of GR, SOD, Cys-C,Hcy and Lp(a) in the two groups were detected and compared after admission and during physical examination. The degree of neurological deficit in patients with CIS was classified into mild (NIHSS：2 ～ 4 points，n=35), moderate (NIHSS：5 ～ 15 points，n=47), moderate-severe (NIHSS：16 ～ 20 points，n=26) and severe (NIHSS：21 ～ 42 points，n=18) according to the National Institutes of Health Stroke Scale (NIHSS). The expression of serum GR, SOD, Cys-C, Hcy and Lp(a) in patients with different degrees of neurological deficit was compared, and the correlation between each indicator and the degree of neurological deficit was analyzed. The observation group received intravenous thrombolytic therapy after admission and was reexamined one day after thrombolysis. After treatment, follow-up visits were conducted for 28 days. According to the patient’s condition (modified Rankin scale), patients were divided into good prognosis （n=94）and poor prognosis groups（n=32）. The levels of each indicator in patients with different prognoses were compared, and the predictive value of GR, SOD, Cys-C, Hcy and Lp(a) expression for poor prognosis and early warning were analyzed. Results The expression levels of serum GR （48.54±3.07U/L）and SOD（157.17±25.47U/ml）in the observation group were lower than those in the control group （61.68±3.15U/L，203.63±18.31U/ml）, while the expression levels of Cys-C（1.24±0.28mg/L）, Hcy（15.21±1.62μmol/ L）and Lp(a)（386.53±52.16mg/L）were higher than those in the control group（0.82±0.23mg/L，9.58±0.60μmol/L， 257.83±45.34mg/L）, with statistically significant differences (t=13.011 ～ 36.582，all P<0.05). As the disease progressed, the expression levels of GR and SOD gradually decreased, while the expression levels of Cys-C, Hcy and Lp(a) gradually increased, with statistically significant differences (F=14.685 ～ 197.041，all P<0.05). Spearman analysis，GR and SOD were negatively correlated with the degree of neurological deficit in patients with CIS (r=-0.814, -0.753, all P<0.05), while Cys-C, Hcy and Lp(a) were positively correlated with the degree of neurological deficit in patients with CIS (r=0.647, 0.782, 0.724, all P<0.05). The expression of GR and SOD in patients with good prognosis at admission and 1 day after thrombolysis was higher than that in patients with poor prognosis (t = 9.109，6.338；2.934，4.358，all P < 0.05), while the expression of Cys-C, Hcy and Lp(a) was lower than that in patients with poor prognosis (t = 5.246，5.118，8.561；4.636，5.298，7.461，all P < 0.05). The AUC（95%CI） of combined prediction of GR, SOD, Cys-C, Hcy and Lp(a) at admission was 0.898 (0.832 ～ 0.945), and the AUC（95%CI） of combined prediction of GR, SOD, Cys-C, Hcy and Lp(a) at 1 day after thrombolysis was 0.931 (0.871 ～ 0.968). The RR （95%CI）values caused by the expression of GR, SOD, Cys-C, Hcy and Lp(a) at 1 day after thrombolysis were 2.868 (1.594 ～ 5.161), 3.194 (1.807 ～ 5.645), 0.155 (0.082 ～ 0.291), 0.150 (0.071 ～ 0.319) and 0.227(0.119 ～ 0.435). Conclusion Abnormal changes in the levels of GR, SOD, Cys-C, Hcy and Lp(a) are closely related to the degree of neurological deficit and prognosis in patients with CIS. Early combined detection of GR, SOD, Cys-C, Hcy and Lp(a) levels has high predictive value and early warning for evaluating the poor prognosis of patients with CIS.
