ObjectiveTo systematically review the efficacy and safety of lumbrokinase capsule for patients with acute ischemic stroke (AIS).MethodsPubMed, EMbase, The Cochrane Library, CNKI, VIP, CBM and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) on lumbrokinase capsule for patients with AIS from inception to 1st December, 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, then, meta-analysis was performed by using Stata 12.0 software.ResultsA total of 33 RCTs involving 4 751 patients were included. The results of meta-analysis indicated that compared with control group, lumbrokinase capsule could improve the treatment efficiency (RR=3.51, 95%CI 2.29 to 5.39, P<0.001), enhance neurological function (SMD=−0.55, 95%CI −0.72 to −0.38, P<0.001) and reduce fibrinogen after treatment (SMD=−0.93, 95%CI −1.41 to −0.44, P<0.001). Reported adverse reactions included dizziness, nausea and gastric discomfort, and no mortality was reported.ConclusionsCurrent evidence shows that lumbrokinase capsule can improve the neurological deficit in patients with AIS. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
Endovascular treatment for acute ischemic stroke has become the main therapy for large vessel occlusion. In addition to stent thrombectomy, in recent years, the application of aspiration thrombectomy is becoming more and more common. The physical principles of aspiration and stent thrombectomy extraction are different. The thrombus is captured by the negative pressure generated by suction through the contact between the reperfusion catheter and the thrombus, thus achieving cerebrovascular recanalization. Currently, more and more researches support the application of aspiration thrombectomy. What are the advantages and disadvantages of the aspiration thrombectomy compared with the stent thrombectomy and how to apply the aspiration technology reasonably are the hot issues concerned by everyone. This paper reviews the application and research progress of aspirating thrombectomy in order to provide reference for clinical treatment decisions.
ObjectiveTo explore the association between glycosylated hemoglobin level and poor prognosis in acute ischemic stroke (AIS) patients treated with intravenous thrombolysis.MethodsThe AIS patients treated with recombinant tissue-type plasminogen activator who were hospitalized in the Department of Neurology of the First Affiliated Hospital of Henan University of Science and Technology from September to December 2020 were retrospectively included. According to different levels of glycosylated hemoglobin, they were divided into pre-diabetic group (5.7%≤glycated hemoglobin≤6.4%), diabetic group (previously diabetic or glycosylated hemoglobin≥6.5%), and non-diabetic group (glycated hemoglobin <5.7%). The relevant information of the patients was collected, and a telephone follow-up was conducted 90 days after discharge. According to the modified Rankin Scale (mRS) score, the patients were divided into the good prognosis group (mRS score≤2) and the poor prognosis group (mRS score>2). Logistic regression analysis was used to determine the risk factors for the poor prognosis of intravenous thrombolysis in patients with AIS.ResultEventually 101 patients were included, including 44 in the non-diabetic group, 24 in the pre-diabetic group, and 33 in the diabetic group. And 64 patients were in the good prognosis group and 37 patients were in the poor prognosis group. Regression analysis results showed that diabetes was associated with poor prognosis 3 months after intravenous thrombolysis in patients with AIS [odds ratio=6.518, 95% confidence interval (1.568, 27.096), P=0.010]; and the higher the National Institutesof Health Stroke Scale score at admission was, the higher the risk of poor prognosis would be [odds ratio=1.421, 95% confidence interval (1.231, 1.640), P<0.001].ConclusionIn AIS patients who received intravenous thrombolysis, diabetes is associated with poor prognosis after 3 months.
Stroke is a disease that seriously affects the quality of life of patients. Its main characteristics are that the incidence rate is increasing year by year, the risk of death is high, and the prognosis of the disease is poor. For patients with acute cerebral artery occlusive ischemic stroke, intravenous thrombolysis alone has a low recanalization rate and poor long-term prognosis. With the development of interventional treatment technology for cerebrovascular disease, intravascular interventional treatment methods such as arterial thrombolysis, stent placement, and mechanical thrombectomy are more and more applied in the ultra-early stage of acute ischemic stroke. This article reviews the progress of mechanical thrombectomy in the treatment of cerebral artery occlusion in patients with acute ischemic stroke.
ObjectiveTo analyze the patterns of recurrent strokes among patients with initial ischemic stroke and investigate the possible predictors of recurrent ischemic stroke. MethodPatients with recurrent strokes after initial ischemic strokes hospitalized in our hospital between January 2008 and December 2012 were included in the study, and the data of general demographic information, life history, past medical history and laboratory test results were all retrospectively analyzed. The patterns of recurrent strokes in patients with initial ischemic stroke were analyzed, and multivariate logistic regression analysis was used to investigate the independent risk factors for recurrent ischemic stroke. ResultsA total of 237 patients were included in this study, including 198 patients with recurrent ischemic stroke and 39 patients with recurrent hemorrhagic stroke. Among patients with recurrent ischemic stroke, there were 137 patients with anterior circulation stroke, 52 with posterior circulation stroke and 9 with multiple infarction. Multivariate logistic regression analysis showed that older age at initial stroke onset[OR=1.968, 95%CI (1.533, 2.152), P=0.009], frequent mood swings[OR=1.345, 95%CI (1.121, 1.783), P=0.011], hyperlipidemia[OR=1.436, 95%CI (1.216, 1.732), P=0.018] and atrial fibrillation[OR=3.417, 95%CI (2.927, 4.897), P=0.005] were independent risk factors for recurrent ischemic stroke. ConclusionsIschemic stroke is the most common pattern of recurrent strokes; and aging, frequent mood swings, hyperlipidemia and atrial fibrillation are possible predictors of recurrent ischemic stroke after the initial ischemic stroke.
ObjectiveTo explore the relevance of an increase in neutrophil count and early neurological deterioration (END) after intravenous thrombolysis in patients with acute ischemic stroke.MethodsA retrospective study was conducted on the patients who received thrombolysis treatment of alteplase within 4.5 hours after onset between January 2017 and November 2018. Based on the existence of END, the patients were divided into the END group and the non-END group. Univariate and multivariate logistic regression, and receiver operating characteristic curves were used to analyze the relevances between END and the indexes such as neutrophil count, lymphocyte count, and neutrophil to lymphocyte ratio (NLR) after thrombolysis. Paired sample t test and Wilcoxon signed-rank test were used to compare the changes of neutrophil and lymphocyte before and after thrombolysis.ResultsA total of 187 patients were included, including 48 in the END group and 139 in the non-END group. Before thrombolysis, the differences of total protein (t=2.130, P=0.035) and albumin (t=2.777, P=0.007) between the two groups were statistically significant, but the differences in other clinical indexes between the two groups were not statistically significant (P>0.05). After thrombolysis, white blood cell count, neutrophil count, NLR, fibrinase degradation product, baseline and change of National Institute of Health Stroke Scale score, proportion of cardiogenic embolism, degree of responsible vascular stenosis and anterior circulation cortical infarction site were all higher in the END group than those in the non-END group (P<0.05). The total protein, albumin, lymphocyte count and prealbumin in the END group were lower than those in the non-END group (P<0.05). Neutrophil in the END group increased significantly (Z=−2.314, P=0.021) after thrombolysis. Neutrophil count [odds ratio=1.288, 95% confidence interval (1.069, 1.552)] was one of the independent influencing factors of venous thrombolysis END, and the specificity was the highest (the sensitivity was 62.5%, and the specificity was 71.9%).ConclusionsAfter thrombolysis, elevated neutrophil count has some relevance to END. Dynamic monitoring on neutrophil count after intravenous thrombolysis treatment can predict the occurrence of END.
Objective To investigate the relationship between systemic inflammation response index (SIRI) and early neurological deterioration (END) and 3-month prognosis in patients with acute ischemic stroke. Methods Patients with acute ischemic stroke treated at West China Hospital of Sichuan University and Deyang People’s Hospital between April 2020 and October 2020 were collected. Clinical data were collected using a unified case form and outcomes were followed up for 3 months. According to the poor prognosis, the patients were divided into END group and non-END group. The multivariate logistic regression analysis was used to explore the relationship of SIRI, END and 3-month prognosis. We drew receiver operating characteristic curve to evaluate the value of related factors in predicting the occurrence of END and poor prognosis after 3 months. Results A total of 242 patients were included, of which 47 (19.42%) were in the END group. There were statistically significant differences between the two groups in National Institutes of Health stroke Scale (NIHSS) score on admission, hypertension, creatinine, urea nitrogen, neutrophils count, lymphocyte count, neutrophil count/lymphocyte count ratio (NLR), lymphocyte count/monocyte count ratio, platelet count/lymphocyte count ratio, complications (besides cerebral edema) and SIRI (P<0.05). Logistic regression analysis showed that NIHSS score on admission, hypertension, SIRI and NLR were independent risk factors for END (P<0.05). SIRI had better predictive value for the occurrence of END than NLR (P<0.05). Compared with the non-END group, the patients in the END group had worse prognosis at 3-month [44.7%(21/47) vs. 17.4% (34/195), P<0.05]. NIHSS score on admission had predictive value for clinical prognosis of acute ischemic stroke patients at 3-month. Conclusion SIRI is an independent risk factor for END in patients with acute ischemic stroke, and there is no independent correlation with the 3-month prognosis.
Objective To investigate the clinical features and prognosis of acute isolated corpus callosum infarction. Methods The clinical and imaging data of patients with acute isolated corpus callosum infarction diagnosed in the Department of Neurology of Beijing Geriatric Hospital and the Department of Neurology of China-Japan Friendship Hospital from February 2017 to February 2021 were retrospectively selected. Patients were divided into groups according to infarction location, infarction size and prognosis. According to the infarction location, the patients were divided into single-site lesion group and multi-site lesions group. According to the infarction size, the patients were divided into large lesion group and small lesion group. According to the prognosis, the patients were divided into good prognosis group and poor prognosis group. The clinical characteristics, etiology and prognosis of these diseases were observed and analyzed. Results A total of 52 patients were included. Among them, there were 32 males (61.5%) and 20 females (38.5%), with an average age of (65.4±7.1) years. The most common risk factors were hypertension (44 cases, 84.6%), hyperlipidemia (32 cases, 61.5%), and diabetes (28 cases, 53.8%). The most common infarction site was splenium in the single-site lesion group (24 cases, 46.2%). The vast majority of patients (92.3%) had nonspecific clinical symptoms, and only 4 (7.7%) had corpus callosum disconnection syndrome. In the TOAST etiological classification, Large-artery atherosclerosis (LAA) was the most common (25 cases, 48.1%), followed by small-artery occlusion (14 cases, 26.9%), the responsible vascular lesions were the most common in the P1/P2 segment of posterior cerebral artery (10 cases) and the A1/A2 segment of anterior cerebral artery (9 cases). There was no significant difference in etiology between the groups with different infarction location and the groups with different infarction size (P>0.05). Forty-four cases (84.6%) had a good prognosis, and 8 cases (15.4%) had a poor prognosis. Combined with multiple risk factors, multiple involvement of lesions and large infarction size were associated with poor prognosis (P<0.05). Conclusions Acute isolated corpus callosum infarction is a rare type of ischemic stroke, with the most common involvement of splenium. Its clinical manifestations are mostly nonspecific, and a few may be manifested as disconnection syndrome. The etiology is mostly LAA, and the overall prognosis of such patients is good, and the poor prognosis may be related to the combination of multiple risk factors and the wide range of infarcts.
In recent years, the incidence rate of ischemic stroke in people living with HIV/AIDS (PLWHA) is increasing, attracting wide attention from scholars at home and abroad. In addition to traditional risk factors of stroke, the secondary ischemic stroke in PLWHA is also affected by HIV infection. This study reviews the incidence rate and risk factors of secondary ischemic stroke in PLWHA, in order to provide a theoretical basis for preventing and reducing the incidence of ischemic stroke in PLWHA.
