Abstract:
Objective To explore the relationship between the levels of serum CXC chemokine ligand 9(CXCL9)and neurogranin(NG)and the condition and prognosis of patients with acute ischemic stroke(AIS).Methods A total of 93 confirmed AIS patients(case group)admitted to Xuzhou First People's Hospi-tal from September 2020 to September 2022 were selected as the research subjects.Another 80 physically healthy individuals with similar gender and age to the case group during the same period were selected as the control group.The case group was divided into the mild group(n=27),the moderate group(n=41),and the severe group(n=25)based on the National Institutes of Health Stroke Scale(NIHSS)score.Three months after treatment,they were divided into the good prognosis group(n=71)and the poor prognosis group(n=22)based on the modified Rankin scale(mRS)score.The levels of serum CXCL9 and NG in each group were detected by enzyme-linked immunosorbent assay,and other clinical data were collected.The correlations be-tween serum CXCL9,NG and NIHSS score and mRS score were analyzed by Pearson product-moment correla-tion analysis.The influencing factors of poor prognosis were analyzed by Logistic regression,and the predic-tive value of poor prognosis was evaluated by the receiver operating characteristic curve.Results Compared with the control group,the levels of serum CXCL9 and NG in the case group increased,and the differences were statistically significant(all P＜0.05).Compared with the mild group,the levels of serum CXCL9 and NG in the moderate group and the severe group increased.The levels of serum CXCL9 and NG in the severe group were higher than those in the moderate group,and the differences were statistically significant(all P＜0.05).Serum CXCL9 and NG were positively correlated with NIHSS score and mRS score(P＜0.05).Com-pared with the good prognosis group,the poor prognosis group had a larger cerebral infarction volume,a more severe condition,and higher levels of serum CXCL9 and NG,the differences were statistically significant(all P＜0.05).Elevated serum CXCL9 and NG were independent risk factors for poor prognosis in AIS patients(OR=1.667,1.589,P＜0.05).The area under the curve of serum CXCL9,NG and their combination for pre-dicting poor prognosis was 0.828,0.809 and 0.931,respectively,and the predictive value of the combination of the two was greater than that of any single indicator(Z=2.556,2.783,P＜0.05).Conclusion Serum CXCL9 and NG are upregulated in AIS patients and are related to the disease condition and prognosis.Early combined detection can assist in clinical assessment of the disease severity and prediction of the risk of poor prognosis.
