ABSTRACT

Abstract Blood-brain barrier (BBB) disruption, inflammation, and cell death are major pathogenic mechanisms in ischemic stroke. Dimethyl fumarate (DMF) has anti-inflammatory and immune-modulatory effects. So, this study aimed to elucidate the effects of DMF on brain ischemia in the middle cerebral artery occlusion (MCAO) model. 69 Sprague-Dawley male rats were allocated into a sham group that was just subjected to surgery stress; vehicle and DMF groups, after MCAO, received vehicle or 30 mg/kg DMF for three days. Neurological scores were evaluated every day. BBB disruption was evaluated by the extravasation of Evans blue. In addition to the measurement of brain water content, the total and infarct volume, numerical density, and the total number of neurons, non-neurons, and dead neurons in the right cortex were estimated by stereological methods. RT-PCR was done to analyze the expression levels of NF-κB and Nrf2. Although brain ischemia treatment with DMF did not have a significant effect on the infarction size, it improved neurobehavioral function, BBB disruption, cerebral edema, increased number of neurons, and expression of Nrf2. It also decreased the number of dead neurons and the expression of NF-κB. DMF beneficial effects on stroke may be mediated through both increase of the Nrf2 and decrease of NF-κB expression

ABSTRACT

Objective:To study the effect of Tanhuo Formula (THW) on the expression of Glial Fibrillary Acidic Protein (GFAP), Caspase-3 and angiogenesis.Methods:Rats were divided into sham group, model group, low-dose THW group, medium-dose THW group, high-dose THW group and Ginaton group according to random number table method. Except the sham group, rats in other groups were subjected to the middle cerebral artery occlusion via a suture method. After 2 hours,rats in the low, medium and high dose of THW groups were gavaged with 0.92, 1.84 and 3.68 g/kg of THW dry extract powder solution respectively, and the Ginaton group were gavaged with 60 mg/kg of Ginaton, once every 24 hours for 3 days. Rats in sham operation group and model group were given equal volume of normal saline by gavage. The limb symmetry score was used to evaluate limb dysfunctions. The immunofluorescence staining of GFAP and Caspase-3 were applied to assess astrocyte activation and neuronal apoptosis, respectively. The double-labeled immunofluorescence staining of platelet-endothelial cell adhesion molecule (CD31) and chondroitinsulphate peoteoglycan (NG2) were performed to detect angiogenesis.Results:Compared with the model group, rats in the high-dose of THW group showed increased limb symmetry score ( P<0.01 or P<0.05), increased number of Caspase-3 (cortex: 765.0±122.4 vs. 1 131.0±392.9; striatum: 895.9±389.8 vs. 1 401.9±453.1) ( P<0.01 or P<0.05) and CD31 +/NG2 + (cortex: 1 355.0±257.9 vs. 825.4±308.1; striatum: 1 290.9±400.9 vs. 675.2±259.7) ( P<0.01) positive cells in the periinfarct cortex and striatum, and attenuated the integrated optical density of GFAP in the perilesional cortex (4 210.00±1 226.38 vs. 7 935.78±2 001.98) ( P<0.01). Conclusions:THW could ameliorate the limb functional disorders, inhibit astroglia activation, down-regulate the expression of Caspase-3, and enhanced angiogenesis in MCAO rats.

ABSTRACT

Vascular cognitive impairment (VCI) is the second most common type of dementia after Alzheimer's disease. As the pathway between the central nervous system and gastrointestinal tract, brain-gut axis has become one of the research hotspots in the pathogenesis of many diseases. Intestinal flora imbalance may mediate or affect vascular risk factors such as atherosclerosis, hypertension, metabolic diseases, and ischemic stroke, and finally accelerate the occurrence and development of VCI. This article reviews the literature on intestinal flora and VCI as well as its main risk factors, in order to provide new ideas for the prevention and treatment of VCI.

ABSTRACT

Objective:To investigate the correlation between obstructive sleep apnea (OSA) and triglyceride-glucose (TyG) indexin patients with ischemic stroke.Methods:Patients with ischemic stroke underwent sleep breathing monitoring in Nanjing Stroke Registry Program from August 2020 to August 2021 were retrospectively enrolled. According to apnea-hypopnea index (AHI), the patients were divided into no/mild OSA group (AHI≤15 events/h) and moderate to severe OSA group (AHI>15 events/h). The TyG index was calculated according to triglycerides and fasting blood glucose, and the patients were grouped by quartile. The relationship between moderate to severe OSA and TyG index was determined by ordinal multinomial logistic regression analysis. Pearson correlation analysis was used to evaluate the correlation between TyG index and AHI. Results:A total of 155 patients with ischemic stroke were enrolled in the study, including 66 patients in the no/mild OSA group, 89 in the moderate to severe OSA group; 39 in the Q1 group (TyG index ≤8.46), 39 in the Q2 group (TyG index 8.47-8.78), 39 in the Q3 group (TyG index 8.79-9.17), and 38 in the Q4 group (TyG index >9.17). Ordinal multinomial logistic regression analysis showed that after adjusting for potential confounding factors, higher fasting blood glucose (odds ratio 2.370, 95% confidence interval 1.745-3.222; P<0.001) and moderate to severe OSA (odds ratio 2.377, 95% confidence interval 1.217-4.646; P=0.011) had significant independent positive correlation with TyG index. Pearson correlation analysis showed that AHI was positively correlated with the TyG index in patients with ischemic stroke ( r=0.209, P=0.011). Conclusion:OSA is independently correlated with TyG index in patients with ischemic stroke.

ABSTRACT

Objective:To investigate the predictive value of platelet-to-neutrophil ratio (PNR) on hemorrhagic transformation (HT) and poor outcomes at 90 d after intravenous thrombolysis (IVT) in patients with acute ischemic stroke (AIS).Methods:Patients with AIS received IVT in Hefei Second People's Hospital from July 2019 to June 2021 were retrospectively enrolled. HT was defined as intracerebral hemorrhage found by CT reexamination within 24 h after IVT, and the poor outcome was defined as the modified Rankin Scale score ≥3 at 90 d after onset. Multivariate logistic regression analysis was used to determine the independent predictors of HT and poor outcomes at 90 d, and the predictive value of PNR on HT and poor outcomes at 90 d was analyzed by receiver operating characteristic (ROC) curve. Results:A total of 202 patients with AIS treated with IVT were included, of which 32 had HT and 50 had poor outcomes at 90 d after onset. Multivariate logistic regression analysis showed that PNR at 24 h after IVT was significantly and independently negatively correlated with the poor outcomes (odds ratio [ OR] 0.959, 95% confidence interval [ CI] 0.928-0.991; P=0.012); PNR at admission ( OR 0.886, 95% CI 0.827-0.948; P<0.001) and PNR at 24 h after IVT ( OR 0.923, 95% CI 0.879-0.969; P=0.001) were significantly independently and negatively correlated with HT. ROC curve analysis showed that the area under the curve of PNR at 24 h after IVT for predicting poor outcomes was 0.733 (95% CI 0.659-0.807; P=0.012), the best cutoff value was 35.03, and the predictive sensitivity and specificity were 70.4% and 74%, respectively. The area under the curve of PNR at admission for predicting HT was 0.830 (95% CI 0.774-0.886; P<0.001), the best cutoff value was 34.81, and the predictive sensitivity and specificity were 70% and 93.7%, respectively. The area under the curve of PNR at 24 h after IVT for predicting HT was 0.770 (95% CI 0.702-0.839; P=0.001), the best cutoff value was 41.73, and the predictive sensitivity and specificity were 53.5% and 96.9%, respectively. Conclusion:For patients with AIS treated with IVT, lower PNR at 24 h after IVT is an independent predictor of the poor outcomes at 90 d, while PNR at admission and 24 h after IVT are the independent predictors of HT.

ABSTRACT

Objective:To investigate the efficacy and safety of intravenous thrombolysis based on diffusion-weighted imaging (DWI) and fluid-attenuated inversion recovery (FLAIR) mismatch in patients with wake-up stroke (WUS).Methods:Patients with acute ischemic stroke received alteplase intravenous thrombolysis in the Stroke Center, the Second People's Hospital of Hefei from July 2019 to June 2021 were enrolled retrospectively. According to the time of finding the symptoms, they were divided into WUS group and non-WUS group. The demographic and baseline clinical data were documented and compared between the two groups. The efficacy endpoint was the clinical outcome assessed by the modified Rankin Scale (MRS) score at 90 d after onset. 0-2 was defined as a good outcome, and >2 were defined as a poor outcome. The primary safety endpoint was symptomatic intracranial hemorrhage (sICH); the secondary safety endpoint was death within 90 d after onset. Multivariate logistic regression analysis was used to determine the independent risk factors for poor outcome. Results:A total of 256 patients with acute ischemic stroke were enrolled, including 155 males (60.5%), aged 63.0±8.53 years. The median time from symptom onset to intravenous thrombolysis was 130.5 min, and the median baseline National Institutes of Health Stroke Scale (NIHSS) score was 7. Forty-eight patients (18.7%) were WUS and 208 (81.3%) were non-WUS; 186 (72.7%) had a good outcome and 70 (27.3%) had a poor outcome. There were no significant differences in 90 d good outcome rate (79.2% vs. 71.2%; χ2=1.260, P=0.262), sICH incidence (4.2% vs. 5.3%; χ2=0.102, P=0.750) and 90 d mortality (2.1% vs. 3.4%; χ2=0.000, P=1.000) between the WUS group and the non-WUS group. The baseline NIHSS score, the time from symptom onset to intravenous thrombolysis and the proportion of patients with cardiogenic embolism in the poor outcome group were significantly higher than those in the good outcome group (all P<0.05). Multivariate logistic regression analysis showed that the baseline NIHSS score (odds ratio 1.670, 95% confidence interval 1.453-1.919; P<0.001) and the time from symptom onset to intravenous thrombolysis (odds ratio 1.007, 95% confidence interval 1.000-1.015; P=0.043) were the independent risk factors for the poor outcome. Conclusion:The efficacy and safety of intravenous thrombolysis in DWI-FLAIR-mismatched wake-up stroke patients are comparable to those of acute ischemic stroke within the time window.

ABSTRACT

Obesity is a recognized risk factor for stroke. However, many studies have shown that compared with normal weight and underweight patients, obese or overweight patients with ischemic stroke have lower risk of death and better functional outcome, suggesting that there is an obesity paradox in patients with ischemic stroke. In contrast, the obesity paradox was not observed in patients receiving reperfusion therapy, including intravenous thrombolysis and endovascular therapy. Therefore, whether there is obesity paradox in ischemic stroke is still controversial. Further high-quality evidence is needed to clarify the correlation between body weight and the outcome of ischemic stroke.

ABSTRACT

As the most effective treatment for acute ischemic stroke, intravenous thrombolysis can not only improve the outcome of patients, but also affect post-stroke depression (PSD) through direct or indirect mechanisms. Therefore, it is of great clinical significance to explore the effect of intravenous thrombolysis on PSD. This article reviews the characteristics of PSD, the possible impact and mechanisms of intravenous thrombolysis on PSD, and the prevention and treatment of PSD.

ABSTRACT

More and more studies have shown that peripheral blood cell counts, including neutrophils, eosinophils, monocytes, lymphocytes, erythrocytes, platelet counts and related ratios are associated with the clinical outcome of patients with acute ischemic stroke after intravenous thrombolysis. Therefore, as a biomarker to predict the outcome of patients with stroke, peripheral blood cell count and related ratio have important clinical application value. This article reviews the predicting value of blood cell count and related ratios for the outcome of intravenous thrombolysis in patients with acute ischemic stroke.

ABSTRACT

Objective:To investigate the effect of aspirin on the outcomes in adult patients with ischemic moyamoya disease treated with encephaloduroarteriosynangiosis (EDAS).Methods:Adult patients with ischemic moyamoya disease treated EDAS in the Department of Neurosurgery, the Fifth Medical Center, PLA General Hospital from January 2015 to September 2018 were enrolled retrospectively. The control group only received EDAS treatment, and the aspirin group received EDAS and aspirin antiplatelet treatment. The data of the both groups were analyzed retrospectively and the effective rate of operation, the incidence of perioperative intracerebral hemorrhage, the incidence of recurrent cerebrovascular events at 6 months after operation and the improvement rate of the modified Rankin Scale (mRS) score were compared.Results:A total of 120 adult patients with ischemic moyamoya disease were enrolled, including 60 in the aspirin group and 60 in the control group. EDAS was performed on 107 cerebral hemispheres in both groups. The operative effective rate in the aspirin group was significantly higher than that in the control group (82.24% vs. 65.42%; χ2=7.836, P=0.005). There was no perioperative cerebral hemorrhage event in the aspirin group and the control group. There was no significant difference in the incidence of cerebral infarction within 6 months after operation, but the incidence of transient ischemic attack in the aspirin group was significantly lower than that in the control group (15% vs. 40%; χ2=9.404, P=0.002). In addition, the improvement rate of mRS score in the aspirin group at 6 months after operation was significantly higher than that in the control group (85% vs. 63.33%; χ2=7.350, P=0.007). Conclusions:The combination of EDAS and aspirin can effectively improve the outcomes of adult patients with ischemic moyamoya disease without increasing the risk of perioperative intracerebral hemorrhage.

ABSTRACT

Objective:To investigate the correlation between serum brain-derived neurotrophic factor (BDNF) and post-stroke cognitive impairment (PSCI) in patients with acute ischemic stroke, and to evaluate its predictive value for PSCI.Methods:Patients with acute ischemic stroke admitted to the Affiliated Hospital of Jining Medical University from April 2018 to September 2020 were prospectively enrolled. Cognitive impairment was assessed by Montreal Cognitive Assessment (MoCA) at 3 months after onset. Multivariate logistic analysis was used to determine the independent correlation between serum BDNF and PSCI, and receiver operating characteristics (ROC) curve was used to evaluate its predictive value for PSCI. Results:A total of 511 patients with acute ischemic stroke were enrolled, including 332 males (65.0%), aged 60.67±10.18 (range 49-80) years. The median score of the National Institutes of Health Stroke Scale (NIHSS) at the baseline was 5.0 (interquartile range 2.7-6.7), and 413 patients (80.8%) had anterior circulation stroke. The median of serum BDNF was 11.54 μg/L (interquartile range 6.13-16.25 μg/L). PSCI occurred in 310 patients (60.7%). Univariate analysis showed that there were significant differences in age, history of previous transient ischemic attack, baseline NIHSS score and serum BDNF between the PSCI group and the non-PSCI group (all P<0.05). Multivariate logistic analysis showed that there was a significant independent correlation between serum BDNF and PSCI (odds ratio 0.514, 95% confidence interval 0.356-0.807; P=0.005). ROC curve analysis showed that the area under the curve of serum BDNF predicting PSCI was 0.863 (95% confidence interval 0.830-0.896; P<0.001). The best cut-off value was 10.78 μg/L, and the sensitivity and specificity were 74.9% and 86.8% respectively. Conclusion:Higher baseline serum BDNF was a protective factor for PSCI and had good predictive value for PSCI.

ABSTRACT

Objective:To investigate the effect of hemorrhagic transformation (HT) and its different subtypes on the clinical outcome of patients with acute ischemic stroke (AIS).Methods:Patients with AIS within 24 h of onset treated in Henan Provincial People's Hospital from January 2018 to January 2021 were retrospectively enrolled. HT was defined as intracranial hemorrhage found by CT reexamination within 7 d after the onset of AIS, and further divided into hemorrhagic infarction (HI) and parenchymal hematoma (PH) according to the classification standard of European Cooperative Acute Stroke Study (ECASS)-Ⅱ. The modified Rankin Scale was used to evaluate the outcome at 90 d after onset. 0-2 was defined as good outcome and 3-5 were defined as poor outcome. Multivariate logistic regression analysis was used to determine the independent influencing factors of the outcomes. Results:A total of 822 patients were enrolled, including 478 males (58.2%), aged 60.6±10.6 years. The median score of the baseline National Institutes of Health Stroke Scale (NIHSS) was 8 (interquartile range: 6-12). Two hundred and eighty-two patients (34.4%) developed HT and 447 (54.4%) had poor outcomes. Multivariate logistic regression analysis showed that PH-1 (odds ratio [ OR] 2.461, 95% confidence interval [ CI] 1.285-4.712; P=0.007), PH-2 ( OR 5.291, 95% CI 1.178-23.758; P=0.030), blood glucose at admission ( OR 1.063, 95% CI 1.018-1.109; P=0.005) and baseline NIHSS score ( OR 1.124, 95% CI 1.076-1.175; P<0.001) were the independent influencing factors of the poor outcomes. Conclusion:Different HT subtypes have different effects on the outcomes of patients with AIS, among which PH-1 and PH-2 are the independent risk factors for poor outcomes.

ABSTRACT

Objective:To investigate the predictive value of baseline peripheral blood neutrophil to lymphocyte ratio (NLR), National Institutes of Health Stroke Scale (NIHSS) score combined with collateral circulation Tan score for the outcome of intravenous thrombolysis in patients with acute anterior circulation large vessel occlusive stroke.Methods:Patients with acute anterior circulation large vessel occlusive stroke received alteplase intravenous thrombolysis in the Departmet of Neurology, the Second Affiliated Hospital of Anhui Medical University from January 2019 to May 2021 were enrolled retrospectively. The modified Rankin Scale score was used to evaluate the outcomes at 90 d after thrombolysis. 0-2 was defined as good outcome and 3-6 were defined as poor outcome. The demographics, clinical data and imaging data between the good outcome group and the poor outcome group were compared. Multivariate logistic regression analysis was used to determine the independent influencing factors of the outcome of thrombolysis, and the receiver operating characteristic (ROC) curve was used to analyze the predictive value of NLR, NIHSS score, Tan score and their combination on the outcome of intravenous thrombolysis. Results:A total of 118 patients with acute anterior circulation large vessel occlusive stroke were enrolled during the study. Their age was 67.73±11.91 years, and there were 71 males (60.2%). Fifty-eight patients (49.2%) were in the good outcome group and 60 (50.8%) were in the poor outcome group. Univariate analysis showed that there were significant differences in NLR, collateral circulation Tan score and baseline NIHSS score between the good outcome group and the poor outcome group (all P<0.05). Multivariate logistic regression analysis showed that NLR (odds ratio [ OR] 1.299, 95% confidence interval [ CI] 1.005-1.679; P=0.046), baseline NIHSS score ( OR 1.150, 95% CI 1.037-1.275; P=0.008), collateral circulation Tan score ( OR 0.298, 95% CI 0.160-0.556; P<0.001) were independently associated with the outcomes. ROC curve analysis showed that the areas under the curve of NLR, baseline NIHSS score, Tan score and their combination for predicting poor outcome were 0.640, 0.752, 0.823 and 0.870, respectively. Conclusions:Peripheral blood NLR before thrombolysis, baseline NIHSS score and collateral circulation Tan score could predict the outcomes after intravenous thrombolysis in patients with acute anterior circulation large vessel occlusive stroke, and the combination of the three had a higher predictive value.

ABSTRACT

Objective:To investigate the correlation between serum CXCL12 and the outcomes after intravenous thrombolytic therapy in patients with acute ischemic stroke.Methods:Consecutve patients with acute ischemic stroke treated with intravenous thrombolytic therapy in the Department of Neurology, the First Affiliated Hospital of Soochow University from January 1, 2020 to August 31, 2021 were enrolled retrospectively. Serum CXCL12 was measured by enzyme-linked immunosorbent assay within 24 h of onset. No improvement in early neurological function was defined as the National Institutes of Health Stroke Scale (NIHSS) 24 h after thrombolysis decreased by <4 compared with the baseline. The clinical outcome was evaluated by the modified Rankin Scale at 90 d after onset, and >2 were defined as a poor outcome. Multivariate logistic regression analysis was used to evaluate the correlation between serum CXCL12 and the outcome after intravenous thrombolysis, and the predictive value of serum CXCL12 for no improvement of early neurological function and poor short-term outcome was analyzed by the receiver operating characteristic (ROC) curve. Results:A total of 66 patients were enrolled, and the serum CXCL12 was 15.72±6.52 g/L. Twenty-seven patients (40.9%) had poor outcomes, and 34 (51.5%) had no improvement in early neurological function. Multivariate logistic regression analysis showed that higher serum CXCL12 was an independent predictor of poor outcome (odds ratio [ OR] 1.245, 95% confidence interval [ CI] 1.093-1.419; P=0.001) and no improvement in early neurological function ( OR 1.250, 95% CI 1.100-1.420; P=0.001). ROC curve analysis showed that the area under the curve of serum CXCL12 for predicting poor outcome was 0.793 (95% CI 0.679-0.908), the best cut-off value was 15.38 μg/L, and the corresponding sensitivity and specificity were 81.5% and 76.9%, respectively. The area under the curve of serum CXCL12 for predicting no improvement of early neurological function was 0.849 (95% CI 0.748-0.951), and the best cut-off value was 15.68 μg/L, and the corresponding sensitivity and specificity were 76.5% and 87.5%, respectively. Conclusion:Serum CXCL12 had a better predictive value for the outcomes of patients with acute ischemic stroke after intravenous thrombolytic therapy.

ABSTRACT

Because the clinical studies of neuroprotective drugs ended in failure, the Stroke Treatment Academy Industry Roundtable recommended the use of non-human primates for preclinical research on stroke. Non-human primates are the bridge between basic experiment and clinical research, and the experimental results are of great reference value. However, non-human primate stroke models have a variety of neurological deficits and behavioral evaluation methods, and the scoring methods also have their own emphases. It is easy to have differences in the evaluation, or there are deficiencies in the scale itself, resulting in inaccurate scoring, which directly affects the experimental results and the implementation of subsequent research. This article summarizes the neurological deficits and behavioral evaluation methods of non-human primate stroke model.

ABSTRACT

There is a certain relationship between chemotherapy and stroke in cancer patients. Its mechanism may be associated with the increase of the prevalence of traditional vascular factors, the promotion of coagulation dysfunction, the induction of anemia, the impairment of cardiac function, and vascular inflammation. The pathophysiological mechanism of chemotherapy-associated stroke is still in the exploratory stage. This article reviews the pathophysiological mechanism, monitoring indicators, and diagnosis and treatment progress of stroke in cancer patients during chemotherapy.
