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.
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.
Diabetes mellitus patients have the characteristics of higher morbidity of ischemic stroke, severe symptoms, more recurrent stroke and higher mortality. Current studies have shown that stroke patients with or without diabetes mellitus have different pathophysiological mechanisms during stroke progress. Accordingly, treatment that is beneficial to non-diabetes mellitus patients may not be beneficial to diabetes mellitus stroke patients. This article reviews the current research status of pathophysiological mechanism of diabetes mellitus complicated with ischemic stroke, and provides reference for the relevant research of drug intervention in diabetes mellitus patients complicated with stroke.
Acute ischemic stroke is the most common type of stroke. Hemorrhagic transformation is one of its serious complications, which may lead to severe neurological deterioration and poor prognosis. The occurrence of hemorrhagic transformation is mainly related to the inflammatory mechanism after infarction, blood-brain barrier injury, ischemia-reperfusion injury and abnormal coagulation function. Identification of early predictors of hemorrhagic transformation can help reduce its incidence and severity. However, the mechanism of hemorrhagic transformation is complex, and there is currently no unified standard for its prediction. This article aims to review the related mechanisms and early predictors of hemorrhagic transformation after stroke, in order to provide a reference for early identification and prevention.
Objective To assess the clinical application of lysophosphatidic acid (LPA) as the early warning index for cerebral ischemic stroke (CIS). Methods Trials were collected through electronic searches of PubMed, The Cochrane Library, CBM, CNKI, Wanfang, and VIP (from the date of database establishment to June 2009). We screened the retrieved studies according to the predefined inclusion and exclusion criteria, evaluated the quality of the included studies, performed descriptive analysis and meta-analysis with The Cochrane Collaboration’s RevMan 4.2 software. Results A total of 22 studies were included. The results of meta-analyses showed that, there was a significant difference about LPA level in cerebral infarction (CI) group vs. healthy control group (WMD=2.00, 95%CI 1.85 to 2.15), and in transient ischemia attach (TIA) group vs. healthy control group (WMD=2.48, 95%CI 2.18 to 2.78); and a difference was noted about 24 hours LPA level in CI group vs. healthy control group (WMD=2.40, 95%CI 1.81 to 2.99). Conclusions According to the included studies, the contents of LPA is higher in CIS than that in healthy control group. It would be helpful to measure LPA in the TIA period for intervention. However, more high quality trials are expected for further study, in order to prove the value of LPA as early warning index because of the heterogeneity and poor quality of the current included studies.
Progressive ischemic stroke is one of the major diseases damaging the health of Chinese people. Its pathogenesis is complex and there are many influencing factors, but the treatment methods are limited. In recent years, the rapid development of neuroimaging and the results of various clinical trials have been reported in succession, which have made new progress in the clinical diagnosis and treatment of progressive ischemic stroke. This paper summarizes the progress of progressive ischemic stroke, introduces its pathogenesis (including increased intracranial pressure and reduced perfusion pressure, thrombosis progression, hemorrhagic transformation, cerebral edema, and inflammatory response), influencing factors, predictive indicators (including image indicators, biochemical indicators, and molecular biology indicators) and treatment (including admission to “stroke unit”, intravascular treatment, platelet aggregation inhibition treatment, anticoagulation treatment, and general treatment), to provide references for preventing the occurrence and development of progressive ischemic stroke, assessing the condition, guiding treatment and improving the prognosis.
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.
Objective To evaluate the reporting quality of randomized controlled trials (RCTs) on acupuncture for acute ischemic stroke. Methods Six databases including The Cochrane Central Register of Controlled Trials (CENTRAL, Issue 4, 2005), MEDLINE (1966 to December 2005), EMbase (1984 to December 2005), China National Knowledge Infrastructure (CNKI, 1994 to December 2005), China Biomedicine Database disc (CBMdisc, 1980 to December 2005), VIP (a full text issues database of China, 1989 to December 2005) were searched systematically. Handsearch for further references was conducted. Language was limited to Chinese and English. We identified 74 RCTs that used acupuncture as an intervention and assessed the quality of these reports against the Consolidated Standards for Reporting of Trials (CONSORT) statement and Standards for Reporting Interventions in Controlled Trials of Acupuncture (STRICTA).Results In regard to the items in the CONSORT statement, 54 (73%) RCTs described baseline demographic and clinical characteristics in each group. Twenty-six (35%) mentioned the method of generating the random sequence, with 4 (5%) using a computer allocation. Only 6 (8%) RCTs had adequate allocation concealment, with 5 RCTs using sealed opaque envelopes and 1 RCT using centralized computer allocation. Only 8 (11%) RCTs used blinding, including 5 described as double-blind. Four (5%) RCTs reported the sample size calculation and 5 (7%) RCTs reported that an intention-to-treat (ITT) analysis. In regard to the items in STRICTA , only 4 (5%) RCTs reported the numbers of needles inserted. In 35 (47%) RCTs the needle type was reported, but only 26 (35%) mentioned the depths of insertion. Only 1 (1%) RCT mentioned the length of clinical experience and 6 (8%) RCTs reported the background of the acupuncture practitioners, but none stated the duration of their training.Conclusion The reporting quality of RCTs of acupuncture for acute ischemic stroke was low. The CONSORT statement and STRICTA should be used to standardize the reporting of RCTs of acupuncture.
Objectives To assess the efficacy and safety of dl-3-butylphthalide for patients with acute ischemic stroke. Methods We collected randomized controlled trials, which compared dl-3-butylphthalide agents with placebo or open control in patients with acute ischaemic stroke, by searching the electronic bibliographic databases, scanning references listed in articles and handsearching journals. Meta-analysis was conducted based on the methods recommended by the Cochrane Collaboration. Results Twenty-one trials involving 2 123 patients were included, of which 2 were placebo-controlled and 19 were open-label controlled. Meta-analysis of 10 trials (n=958), in which neurological deficits were assessed by CSS, suggested that there were significant differences favoring butylphthalide in the mean change of neurological deficits’ score during the treatment period [MD=2.30, 95%CI (1.57, 3.03)]. Meta-analysis of 6 trials (n=590), in which neurological deficits were assessed by NIHSS, also favored butylphthalide [MD=2.06, 95%CI (0.65, 3.46)]. Adverse events (AEs) were reported in 13 trials. Gastrointestinal discomfort (1.7%~8%) and abnormal liver function including abnormal ALT (1.4%~17.5%) and abnormal AST (1.9%~8.82%) were the two most common AEs. However, no severe adverse events (SAEs) were reported. Numbers of dead and dependent patients at the end of followup (at least three months) were not reported in the 21 included trials. Quality of life was not assessed in any of the trials. Conclusion Dl-3-butylphthalide can improve the neurological function after acute ischemic stroke and appears to be safe. However, further study is needed to confirm its effects for lowering rates of death and dependency.
ObjectiveTo explore the association between prediabetes and poor outcome in patients with acute ischemic stroke (AIS).MethodsThe patients with first-ever AIS who were hospitalized in the Department of Neurology, the First Affiliated Hospital of Henan University of Science and Technology from September to December 2018 were retrospectively enrolled. According to the different levels of hemoglobin A1c, the patients were divided into prediabetes group, diabetes mellitus (DM) group and non-DM group. The outcome of the patients 3 months after the discharge was assessed by the modified Rankin Scale and dichotomized as good and poor outcomes. ResultsA total of 188 patients were included, and 160 were eventually included. Among them, 66 cases were in the non-DM group, 39 were in the prediabetes group, and 55 were in the DM group; 68 patients were in the poor prognosis group and 92 were in the good prognosis group. There was no statistically significant difference among the non-DM group, prediabetes group, and DM group (P>0.05) except for hyperlipidemia (χ2=7.781, P=0.020), triglyceride (TG) (F=8.220, P<0.001) and admission blood glucose (F=44.356, P<0.001). There was no statistically significant difference between the good prognosis group and the poor prognosis group (P>0.05) except for hyperlipidemia (χ2=4.847, P=0.028), admission blood glucose (t=−2.940, P=0.004), TG (t=−2.766, P=0.006), and NIHSS (Z=−6.038, P<0.001). Prediabetic [odds ratio (OR)=4.053, 95% confidence interval (CI) (1.491, 11.019)] and diabetic [OR=5.986, 95%CI (2.330, 15.379)] patients had a worse prognosis 3 months after the discharge.ConclusionIn adults with first-ever AIS, prediabetes and diabetes were associated with poor prognosis in patients with AIS after 3 months.
