RESUMO
@#Objective To explore the predictive value of neutrophil/lymphocyte ratio (NLR) on the 90 day mortality risk of patients with cardiogenic cerebral embolism (CE).Methods 245 patients with cardiogenic cerebral embolism were analyzed retrospectively.Demographic data,vascular risk factors,laboratory tests and end point events were collected.The patients were divided into survival group and death group according to whether or not there were end-point events.Multifactor logistic regression was used to analyze the influencing factors of endpoint events,to draw ROC curve,and to evaluate the predictive value of NLR on endpoint events.Results Of the 245 cases included in the analysis,145 survived and 100 died.Compared with the survivors,the age,hyperlipidemia,atrial fibrillation,mRS score,white blood cell count,glutathione aminotransferase and neutrophil score in the death group were significantly higher (P<0.01),and there was no significant difference in gender,hypertension,diabetes,family history,smoking,alcohol consumption,red blood cell count,hemoglobin and other blood indicators between the two groups(P>0.05).Multivariate logistic regression analysis showed that age,atrial fibrillation,hyperlipidemia and NLR were independent risk factors for 90-day death.ROC shows AUC=0.7558.When the optimal cutoff value of NLR was 5.65,the sensitivity was 68.0%,and the specificity was 76.6%.Conclusion The increase of NLR at admission is a high risk factor for 90 day death in patients with cardiogenic cerebral infarction,and it has a good predictive value for 90 day death.
RESUMO
@#Objective To study the relationship between FTP and RCI.Methods A total of 1017 inpatients in the Department of Neurology,The Second Affiliated Hospital of Baotou Medical College from January 2020 to October 2021 were retrospectively collected.According to the inclusion and exclusion criteria,943 patients were included in the analysis,including 620 cases of initial cerebral infarction and 323 cases of RCI.The clinical data and incidence of FTP were compared between the two groups.Univariate analysis was performed on the risk factors of RCI,and multivariate Logistic regression was used to analyze the independent risk factors.Results The incidence of FTP in RCI was significantly higher than that in primary cerebral infarction (P<0.01),binary logistic regression showed that FTP,hypertension,diabetes mellitus,coronary heart disease and family history were correlated with the recurrence of cerebral infarction,and the calculated OR values were 2.481,1.486,1.652 and 2.402,respectively (P<0.05).Conclusion The incidence of FTP in patients with RCI is higher than that in patients with primary cerebral infarction and FTP is an independent risk factor for recurrent cerebral infarction.
RESUMO
Objective To investigate the association between matrix metalloproteinase (MMP) -2 C735T and MMP-9 C1562T polymorphisms and TOAST subtypes, the outcome in patients with stroke. Methods A total of 232 patients with ischemic stroke were divided into large artery atherosclerosis (LAA, n =37), cardioembolism (CE, n =31), small artery occlusion (SAO, n =65) stroke, stroke of other demonstrated etiology (SOE, n =2), and stroke of undemonstrated etiology (SUE, n =97) according to TOAST criteria. A total of 235 healthy subjects in the outpatient served as control. Genetic polymorphisms of MMP-2 C735T and MMP-9 C1562T were identified by polymerase chain reaction-restriction fragment length polymorphism.The outcome of patients was evaluated with Barthel Index (BI) at day 21 and 90 after stroke.Results The frequencies of MMp-2 735CC genotype and C allele in the ischemic stroke group (CC genotype: 63.36％ vs. 54.04％,x2 =4. 182, P=0.014; C allele: 79.31％vs. 74.04％,x2 =3. 936, P =0. 047 ) and its LAA subtype ( CC genotype: 78. 37％ vs. 54. 04％, x2 =7. 740, P =0. 005; C allele: 87. 83％ vs. 74. 04％, x2 =6. 655, P =0. 01 ) were significantly higher than those in the control group. The frequencies of MMP-9 1562CT +TT genotype and T allele in the ischemic stroke group (CT +TT genotypes: 21.98％ vs. 13. 19％,x2 =6. 233, P=0.013; T allele: 11.64％ vs. 7. 02％ ,x2 =5. 891, P =0. 015)and its LAA subtype(CT +TT genotypes: 32. 43％ vs. 13. 19％ ,x2 =8. 892, P =0. 003; T allele: 20. 27％ vs. 13.19％ ,x2 =13. 950, P =0. 000). Multivariate logistic regression analysis indicated that risk of ischemic stroke and its LAA subtype with MMP-2 735CC genotype (ischemic stroke: odds ratio [OR]1.099, 95％ confidence interval [CI] 1.038-1.260, P =0.028; LAA: OR 1.360, 95％ CI 1. 167-5. 774, P =0. 009) and with MMP-9 1562TT genotype (ischemic stroke: OR 9. 409,95％ CI 1. 154-76. 722, P =0. 036; LAA: OR 8. 962, 95％ CI 1. 380-58. 218, P =0. 022)increased significantly. There were no significant correlation between the different genotypes of MMP-2 and MMP-9 and the outcome of ischemic stroke. Conclusions Polymorphisms of MMP-2 C735T and -9 C1562Tare associated with ischemic stroke and its subtype large artery atherosclerotic stroke, but not associated with the outcome in patients with ischemic stroke
