目的 研究CXC趋化因子配体4（CXCL4）、基质金属蛋白酶-9（MMP-9）、微小RNA-24（miR-24）对急性脑梗死（ACI）早期神经功能恶化（END）的预测价值。方法 分别选择2020年1月—2021年6月我院收治的30例ACI早期END患者（ACI+END组）,30例单纯ACI患者（ACI组）,同时期30例健康人群作为对照组,检测受试者CXCL4、MMP-9、miR-24表达情况及存在的相关性,分析血清CXCL4、MMP-9、miR-24表达情况与ACI早期发生END的关系。结果 CXCL4、MMP-9水平在对照组、ACI组、ACI+END组中依次升高,miR-24相对表达量依次降低（P<0.05）。血清CXCL4、MMP-9、miR-24水平在轻度、重度患者中呈升高趋势,miR-24相对表达呈降低趋势（P<0.05）。Logistic回归分析血清CXCL4、MMP-9、miR-24表达异常与ACI早期发生END独立相关（P<0.05）。经Pearson相关性分析发现,CXCL4与MMP-9之间呈正相关（r=0.584,P=0.001）;CXCL4、miR-24之间呈负相关（r=-0.569,P=0.001）,MMP-9、miR-24之间呈负相关（r=-0.567,P=0.001）。ROC曲线显示,与CXCL4、MMP-9、miR-24单项预测相比,三项联合对ACI的关系及对早期END的预测价值较高（P<0.05）。结论 CXCL4、MMP-9、miR-24在ACI发生END时出现异常表达,检测CXCL4、MMP-9、miR-24水平对ACI早期END具有一定预测价值,可尽早制定相关措施干预,提高治疗效率。

Objective To study the predictive value of CXC chemokine ligand 4（CXCL4）,matrix metalloproteinase-9（MMP-9）,microRNA-24（miR-24）in early neurological deterioration（END）of acute cerebral infarction（ACI）．Methods A total of 30 patients with ACI early END（ACI+END group）and 30 patients with ACI only（ACI group）who were admitted to our hospital from January 2020 to June 2021 were selected,and 30 healthy people（control group）who underwent physical examination in our hospital during the same period were selected．Expressions of CXCL4,MMP-9,and miR-24 were detected and their correlations were analyzed,and the relationship between the expressions of serum CXCL4,MMP-9,miR-24 and the early occurrence of END in ACI were analyzed．Results The levels of CXCL4 and MMP-9 were increased in the control group,ACI group and ACI+END group in turn,and the relative expression of miR-24 was decreased in turn,and the differences among the groups were statistically significant（P<0.05）．The levels of serum CXCL4,MMP-9,and miR-24 increased in mild and severe patients,while the relative expression of miR-24 decreased,and the differences between groups were statistically significant（P<0.05）．Logistic regression analysis showed that abnormal expressions of serum CXCL4,MMP-9 and miR-24 were independently correlated with the early occurrence of END in ACI（P<0.05）．After Pearson correlation analysis,it was found that there was a positive correlation between CXCL4 and MMP-9（r=0.584,P=0.001）,a negative correlation between CXCL4 and miR-24（r=-0.569,P=0.001）;a negative correlation between MMP-9 and miR-24（r=-0.567,P=0.001）．The ROC curve showed that compared with the single prediction of CXCL4,MMP-9 and miR-24,the predictive value of the combined prediction on ACI and early END were higher（P<0.05）．Conclusions CXCL4,MMP-9,and miR-24 are abnormally expressed in ACI when END occurs．Detection of CXCL4,MMP-9,and miR-24 levels has certain predictive value for early END of ACI,and relevant measures can be formulated as soon as possible to improve treatment efficiency．

Objective To investigate the efficacy of breviscapine combined with alteplase in the treatment of acute cerebral infarction beyond thrombolytic time window. Methods A total of 82 patients with acute cerebral infarction beyond thrombolytic time window were randomly divided into experimental group (40 cases) and control group (42 cases). The control group was treated with alteplase, and the experimental group was treated with breviscapine on the basis of the control group. Before and 2 weeks after treatment, the degree of neurological deficit [National Institutes of Health Stroke Scale (NIHSS)], regional tissue perfusion of cerebral infarction [relative cerebral blood volume (rCBV), cerebral blood flow (CBF)], hemorheological indexes [high shear whole blood viscosity (HSBV), low shear whole blood viscosity (LSBV), plasma viscosity (PV), hematocrit (HCT)], the indexes of oxidative stress [malondialdehyde (MDA) and superoxide dismutase (SOD)] were compared between the two groups. Results After 2 weeks of treatment, NIHSS score, HBSV, LSBV, PV, HCT and MDA levels of the two groups were significantly lower than those before treatment, and those of the experimental group were significantly lower than the control group at the same time (P＜0.05). The rCBV, CBF and SOD levels of the two groups were significantly higher than those before treatment, while those of the experimental group was significantly higher than the control group (P＜0.05). Conclusions Breviscapine combined with alteplase in the treatment of acute cerebral infarction beyond thrombolytic time window had good therapeutic effect, which was beneficial to improve the degree of neurological deficit, increase the perfusion volume of infarcted area, improve the cerebral blood flow of patients, and was beneficial to the prognosis and rehabilitation.
