Abstract:
Objective Toinvestigatethecorrelationsofthelevelsofplasmasolublereceptorfor advanced glycation end product (sRAGE )with the National Institutes of Health Stroke Scale (NIHSS ), grade of white matter lesions,and risk factors for cerebral vascular disease in patients with acute cerebral infarction.Methods Atotalof120patientswithacutecerebralinfarctionwereenrolledretrospectively. They all underwent head MRI. The plasma sRAGE levels of the acute cerebral infarction group and 120 healthy subjects were detected with enzyme-linked immunosorbent assay (ELISA)and were compared. According to the interquartile range (P25 =540 ng/L,P50 =1030 ng/L,P75 =1400 ng/L ),the plasma sRAGE levels were divided into 4 quartiles (Q1 to Q4). Q1:sRAGE<540 ng/L (n=29),Q2:540 ng/L≤sRAGE≤1030 ng/L (n=31),Q3:1030 ng/L < sRAGE≤1400 ng/L (n =30),and Q4:sRAGE >1400 ng/L (n =30 ). The plasma sRAGE levels in the acute cerebral infarction group and the healthy control group were compared using the Wilcoxon rank sum test. Multiple linear regression analysis was used to analyze the correlations of the sRAGE levels with NIHSS scores,grade of cerebral white matter lesions,and cerebrovascular risk factors. Results (1 )The median level of plasma sRAGE was 870 (540.0,1403. 8)ng/L in the acute cerebral infarction group,which was lower than 1032 (727. 5,1721. 5) ng/L in the healthy control group. There was significant difference (P<0. 05). (2)Single factor analysis showed that the smoking rate,NIHSS scores,the types of deep white matter hyperintensity (DWMH),and the estimated glomerular filtration rate(eGFR)among Q1,Q2,Q3 and Q4 quartiles were significant different (all P<0.05). The smoking rate,ratio of patients with high NIHSS score,incidence of severe DWMH and percentage of the patients with normal eGFR in Q1 (n=29)were 62. 1%(n=18), 44. 8%(n=13),55.2%(n=16)and 51. 7%(n=15),respectively,and they had a higher trend than other quartiles. (3)Multiple linear regression analysis showed that the smoking,NIHSS score,eGFR,and severity of DWMH were the influence factors of the levels of plasma sRAGE in patients with acute cerebral infarction.Thereweresignificantdifferences(allP<0.05).Conclusion Theexpressionlevelsofthe plasma sRAGE in patients with acute cerebral infarction group is significantly lower than those in the healthy subjects,and smoking,neurological defect,eGFR,and severity of DWMH are associated the low level of sRAGE. sRAGE may be used as a reference index for predicting the conditions of acute cerebral infarction.
