  • 缺血性卒中后癫痫动物模型的研究进展

    卒中后癫痫(Post-stroke epilepsy,PSE)是指继发于脑卒中的癫痫发作且既往无癫痫发作史,其病因包括出血性脑卒中和缺血性脑卒中。虽然缺血性 PSE 的发生率低于出血性脑卒中,但由于缺血性卒中患病率远高于出血性脑卒中,从而缺血性 PSE 患者也多于出血性 PSE 患者。作为脑卒中的常见并发症,卒中后早期癫痫发作会加重脑组织损伤,直接影响患者预后。为了研究缺血性 PSE 的发病机制,制定合理的治疗方案,构建了各种动物模型。文章就缺血性 PSE 动物模型研究进展进行综述。

  • Efficacy and safety of two different thrombolytic therapies for patients with hyperacute ischemic stroke

    ObjectiveTo observe and compare the efficacy and safety of intravenous thrombolysis with alteplase or urokinase in the first-ever acute ischemic stroke patients arriving at the hospital 3.5-4.5 h after onset.MethodsClinical data of patients with acute ischemic stroke treated in Shihezi People’s Hospital between January 2019 and October 2020 were prospectively collected. The National Insititutes of Health Stroke Scale (NIHSS) score on the 7th day and the 90th day, the modified Rankin Scale (mRS) score and the Blessed Behavior Scale (BBS) score on the 90th day, and symptomatic bleeding within 36 h after thrombolysis were analyzed and compared between the patients receiving alteplase threatment (the alteplase group) and the ones receiving urokinase treatment (the urokinase group).ResultsTotally 96 patients were treated with intravenous thrombolysis. Among them, 58 patients received alteplase threatment and 38 received urokinase treatment. The difference in NIHSS, mRS, or BBS scores between the two groups before treatment was not statistically significant (P>0.05). On the 90th day after treatment, the NIHSS, mRS, and BBS scores of the alteplase group were 3.59±3.73, 2.26±1.26, and 15.33±8.28, respectively, and those of the urokinase group were 5.95±4.88, 3.00±0.87, and 20.37±11.80, respectively; the differences between the two groups were all statistically significant (P<0.05). There was no significant difference in the rate of symptomatic intracerebral hemorrhage between the two groups within 36 h after treatment (P>0.05). Multiple linear regression analyses showed that the treatment method was related to the NIHSS score on the 7th day, the NIHSS score on the 90th day, the mRS score on the 90th day, and the BBS score on the 90th day (P<0.05), the history of heart disease was related to the mRS score on the 90th day (P<0.05), and the income was related to the BBS score on the 90th day (P<0.05).ConclusionFor the hyperactue ischemic stroke, the overall effect of alteplase treatment may be better than that of urokinase treatment.

  • Correlation between Atrial Fibrillation and Prognosis of Patients with Ischemic Stroke after Intravenous Thrombolysis: A Meta-Analysis

    ObjectiveTo systematically review the correlation between atrial fibrillation and prognosis of patients with ischemic stroke after intravenous thrombolysis. MethodsLiterature search was carried out in PubMed, EMbase, Web of Science, The Cochrane Library (Issue 4, 2014), CBM and WanFang Data up to April 2014 for the domestic and foreign cohort studies on atrial fibrillation and prognosis of patients with ischemic stroke after intravenous thrombolysis. Two reviewers independently screened literature according to inclusion and exclusion criteria, extracted data, and assessed methodological quality of included studies. Then meta-analysis was performed using RevMan 5.2. ResultsA total of 7 cohort studies were finally included involving 69 017 cases. The results of meta-analysis showed that, compared with patients without atrial fibrillation, atrial fibrillation reduced 3-month favourable nerve function of patients with atrial fibrillation (OR=0.85, 95%CI 0.73 to 0.98, P=0.03) but did not influence the risk of death after intravenous thrombolysis (OR=1.47, 95%CI 0.75 to 2.86, P=0.26); and increased the risks of intracranial haemorrhagic transformation (OR=1.36, 95%CI 1.26 to 1.47, P < 0.001) and symptomatic intracranial hemorrhage after intravenous thrombolysis (OR=1.43, 95%CI 1.02 to 1.99, P=0.04). ConclusionFor patients with ischemic stroke, atrial fibrillation does not influence the risk of death, but it increases the risks of intracranial hemorrhage, and worsens 3-month favourable nerve function of after intravenous thrombolysis. For those patients, more assessment before intravenous thrombolysis and more monitoring after intravenous thrombolysis are necessary. Due to limited quality and quantity of the included studies, the abovementioned conclusion still needs to be verified by conducting more high quality studies.

  • The correlation between homocysteine level and overall burden of cerebral small vessel disease in patients with ischemic stroke

    ObjectiveTo investigate the relationship between the level of homocysteine (HCY) and the overall burden of cerebral small vessel disease (CSVD) in patients with ischemic stroke.MethodsA total of 322 patients with first-ever ischemic stroke admitted to the People’s Hospital of Deyang City between January 2016 and December 2017 were enrolled. The patients’ demographic information, clinical information, and serum HCY concentration were collected after admission. The presence or absence of a CSVD was assessed by MRI and the overall burden score for the CSVD was determined. Multivariate logistic regression analysis was used to assess whether serum HCY level was associated with the overall burden of CSVD.ResultsThe median level of HCY was 13.2 μmol/L (inter-quartile range: 4.3 to 22.6 μmol/L). Univariate analysis showed that the difference of HCY levels among patients with different total CSVD scores was statistically significant (F=6.874, P=0.001); Spearman correlation analyses showed that the HCY level grouped by quartiles was correlated to the number of lacunar infarctions (rs=0.267, P=0.001), Fazekas score of white matter lesions (rs=0.122, P=0.042), and enlarged perivascular space (EPV) score (rs=0.319, P=0.001), but was not correlated to cerebral microhemorrhage (rs=−0.010, P=0.869). After multivariate regression analysis to adjust the effects of other factors, compared with the patients with HCY levels in the lowest quartile group, the patients with HCY levels in the highest quartile group were more likely to develop lacunar infarction [odds ratio (OR)=1.892, 95% confidence interval (CI) (1.012, 2.987)], white matter lesions [OR=1.548, 95%CI (1.018, 1.654)], severe EPV [OR=6.347, 95%CI (3.592, 13.978)], and the increase in the CSVD score [OR=2.981, 95%CI (1.974, 5.398)].ConclusionIn patients with ischemic stroke, elevated HCY levels may be associated with the overall burden of the CSVD.

  • Application and research progress of shared decision-making tools in ultra-early vascular recanalization therapy for ischemic stroke

    This article explores the application and research progress of shared decision-making (SDM) tools in ultra-early vascular recanalization therapy for ischemic stroke, focusing on analyzing the functional characteristics and advantages and disadvantages of various tools. Based on functional goals, SDM tools can be divided into four categories: brief decision aids, risk communication tools, patient information tools, and prognosis assessment tools. These tools can assist patients and doctors in making informed treatment decisions quickly in time-sensitive situations, providing a reference for optimizing stroke revascularization treatment. Additionally, SDM tools can facilitate communication between doctors and patients, enabling patients to better understand the risks and benefits of treatment options, leading to choices more aligned with personal preferences and values. Through an in-depth study of these SDM tools, it is expected to improve the diagnostic and treatment efficiency for stroke patients, reduce decision conflicts, promote collaboration between doctors and patients, and provide new ideas and methods for stroke treatment and management.
