Admission clinical characteristics and early clinical outcomes among acute ischemic stroke patients

The purpose of the present study was to investigate the association between admission clinical characteristics and outcomes at discharge among acute ischemic stroke patients in the Chinese population. A total of 2,673 patients with acute ischemic stroke were included in the present study. The clinical characteristics at admission and other study variables were collected for all patients. The study outcome was defined as neurological deficiency （National Institute of Health Stroke Scale score ≥ 10） at discharge or in-hospital death. Compared with the subjects without neurological deficiency at discharge or in-hospital death, the subjects with neurological deficiency at discharge or in-hospital death had a significantly higher prevalence of hyperglycemia or history of atrial fibrillation at admission. Age ≥ 80 years, hyperglycemia, hypertension, and history of atrial fibrillation were significantly associated with neurological deficiency at discharge or in-hospital death after adjustment for other variables. It is concluded that old age （ ≥ 80 years）, hyperglycemia, hypertension and history of atrial fibrillation are significantly associated with neurological deficiency at discharge or in-hospital death among patients with acute ischemic stroke.

Dyslipidemia and Outcome in Patients with Acute Ischemic Stroke

Objective To study the relationship between dyslipidemia and outcome in patients with acute ischemic stroke. Methods Data about 2 568 patients with acute ischemic stroke were collected from 4 hospitals in Shandong Province from January 2006 to December 2008. National Institute of Health Stroke Scale （NIHSS） 〉10 at discharge or death was defined as the outcome. Effect of dyslipidemia on outcome in patients with acute ischemic stroke was analyzed by multivariate logistic regression analysis and propensity score-adjusted analysis, respectively. Results The serum levels of TC, LDL-C, and HDL-C were significantly associated with the outcome in patients with acute ischemic stroke. Multivariate logistic regression analysis and propensity score-adjusted analysis showed that the ORs and 95% CIs were 3.013 （1.259, 7.214）/2.655 （1.298, 5.43）, 3.157 （1.306, 7.631）/3.405 （1.621, 7.154）, and 0.482 （0.245, 0.946）/0.51 （0.282, O.921）, respectively, for patients with acute ischemic stroke. Hosmer-Lemeshow goodness-of-fit test showed no significant difference in observed and predicted risk in patients with acute ischemic stroke （chi-square=8.235, P=0.411）. Conclusion Serum levels of TC, LDL-C, and HDL-C are positively related with the outcome in patients with acute ischemic stroke.

Non-coding RNAs in acute ischemic stroke:from brain to periphery

Acute ischemic stroke is a clinical emergency and a condition with high morbidity,mortality,and disability.Accurate predictive,diagnostic,and prognostic biomarkers and effective therapeutic targets for acute ischemic stroke remain undetermined.With innovations in high-throughput gene sequencing analysis,many aberrantly expressed non-coding RNAs(ncRNAs)in the brain and peripheral blood after acute ischemic stroke have been found in clinical samples and experimental models.Differentially expressed ncRNAs in the post-stroke brain were demonstrated to play vital roles in pathological processes,leading to neuroprotection or deterioration,thus ncRNAs can serve as therapeutic targets in acute ischemic stroke.Moreover,distinctly expressed ncRNAs in the peripheral blood can be used as biomarkers for acute ischemic stroke prediction,diagnosis,and prognosis.In particular,ncRNAs in peripheral immune cells were recently shown to be involved in the peripheral and brain immune response after acute ischemic stroke.In this review,we consolidate the latest progress of research into the roles of ncRNAs(microRNAs,long ncRNAs,and circular RNAs)in the pathological processes of acute ischemic stroke–induced brain damage,as well as the potential of these ncRNAs to act as biomarkers for acute ischemic stroke prediction,diagnosis,and prognosis.Findings from this review will provide novel ideas for the clinical application of ncRNAs in acute ischemic stroke.

Identification of risk factors and construction of a nomogram predictive model for post-stroke infection in patients with acute ischemic stroke

BACKGROUND Post-stroke infection is the most common complication of stroke and poses a huge threat to patients.In addition to prolonging the hospitalization time and increasing the medical burden,post-stroke infection also significantly increases the risk of disease and death.Clarifying the risk factors for post-stroke infection in patients with acute ischemic stroke(AIS)is of great significance.It can guide clinical practice to perform corresponding prevention and control work early,minimizing the risk of stroke-related infections and ensuring favorable disease outcomes.AIM To explore the risk factors for post-stroke infection in patients with AIS and to construct a nomogram predictive model.METHODS The clinical data of 206 patients with AIS admitted to our hospital between April 2020 and April 2023 were retrospectively collected.Baseline data and post-stroke infection status of all study subjects were assessed,and the risk factors for poststroke infection in patients with AIS were analyzed.RESULTS Totally,48 patients with AIS developed stroke,with an infection rate of 23.3%.Age,diabetes,disturbance of consciousness,high National Institutes of Health Stroke Scale(NIHSS)score at admission,invasive operation,and chronic obstructive pulmonary disease(COPD)were risk factors for post-stroke infection in patients with AIS(P<0.05).A nomogram prediction model was constructed with a C-index of 0.891,reflecting the good potential clinical efficacy of the nomogram prediction model.The calibration curve also showed good consistency between the actual observations and nomogram predictions.The area under the receiver operating characteristic curve was 0.891(95%confidence interval:0.839–0.942),showing predictive value for post-stroke infection.When the optimal cutoff value was selected,the sensitivity and specificity were 87.5%and 79.7%,respectively.CONCLUSION Age,diabetes,disturbance of consciousness,NIHSS score at admission,invasive surgery,and COPD are risk factors for post-stroke infection following AIS.The nomogram prediction model established based on these factors exhibits high discrimination and accuracy.

Interaction between Antihypertensive Therapy Class and Pulse Pressure on Outcomes Following Acute Ischemic Stroke

Goal: The effect of pulse pressure and interactions with type of antihypertensive therapy on mortality after acute ischemic stroke has not been previously evaluated. Materials and Methods: A retrospective cohort study was conducted to evaluate the independent and interactive effects of pulse pressure and antihypertensive class (specifically angiotensin converting enzyme inhibitor/angiotensin type 1 receptor blocker, or beta blocker) on mortality following acute ischemic stroke. Findings/Conclusions: 343 patients were identified with 49 months of follow-up. Baseline pulse pressure was 64 mmHg and age was 66.5 years. Patients were divided at a pulse pressure of 70. Patients with pulse pressure ≥ 70 were older (p < 0.001) and had higher comorbid vascular burden (p = 0.031) than those with pulse pressure < 70. Pulse pressure did not remain a significant predictor of follow-up mortality after adjustment for baseline comorbidities. Angiotensin converting enzyme inhibitor/angiotensin type 1 receptor blocker based therapy was associated with lower follow-up mortality when beta blocker was not used in pulse pressure < 70 group (odds ratio 0.07, 95% confidence interval 0.01 - 0.48). Prospective analysis will be needed to confirm the protective effect of angiotensin converting enzyme inhibitor/angiotensin type 1 receptor blocker based on pulse pressure in acute ischemic stroke.

How to Design Economic Predictive Laboratory Panel Evaluating Acute Ischemic Stroke Outcome

Background: acute ischemic stroke (AIS) remains the third cause of death and disability, and acute phase responses, both increasing international normalized ratio (INR) and activated partial thromboplastin time (APTT) are associated with worse outcome. Erythrocyte sedimentation rate (ESR) serves as severity marker, and non-fasting triglycerides (TG) indicates remnants of chylomicrons and very low density lipoproteins potentially pro-inflammatory. Aims: to design predictive economic panel evaluating AIS. Patients and methods: 100(AIS) patients were included, clinically evaluated by Scandinavian Stroke Scale (SSS) and Modified Rankin Score (MRS), subjected to complete blood count (CBC) on Cell-Dyne3700, manual ESR, INR and APTT on SYSMEX-CA1500, serum uric acid (SUA), serum albumin and non-fasting (TG) on Beckman Coulter AU480. Statistical analysis: STATA intercooled version 9.2. Results: odd ratio (OR), confidence interval (CI) of (MRS) in correlation to WBCs count in quartile (Q)3, 4 (OR 8.14, CI 2.29 - 8.90, significant P = 0.01;and OD13.5, CI 3.39 - 53.68, high significant P = 0.001 respectively), to APTT in Q3 (OD 4.15, CI 1.09 - 15.82, P = 0.04), SUA in Q3 (OD 0.19, CI 0.05 - 0.68, P = 0.01), TG in Q3,4 (OD 0.24 CI 0.06 - 0.88, P = 0.03;and OD 0.09, CI 0.02 - 0.34 P = 0.001 respectively) and serum albumin in Q3(OD 0.13, CI 0.04 - 0.51, P = 0.003), insignificant correlations to ESR, INR and platelets. Conclusion: according to (MRS), the economic predictive panel should be included WBCs, APTT, SUA, and non-fasting TG with serum albumin as prognostic tool evaluating functional disability in AIS.

The effect of Huanglian Jiedu Decoction on inflammatory factors and oxidative stress in patients with acute ischemic stroke

Objective:To study the clinical efficacy of Huanglian Jiedu decoction in treating acute ischemic stroke(AIS)and its effects on inflammatory factors and oxidative stress.Method:A total of 53 patients with AIS were recruited as the study subjects and randomly divided into a control group and a treatment group using a random number table method.The control group consisted of 26 patients and the treatment group consisted of 27 patients.The control group received conventional Western medicine treatment.The control group received routine Western medicine treatment,while the treatment group received Huanglian Jiedu decoction based on the control group,with 14 days as a course of treatment.The effects of Huanglian Jiedu decoction on neurological function and activities of daily living were evaluated using the National Institute of Health stroke scale(NIHSS)and activities of daily living(ADL)scores.The effects of Huanglian Jiedu decoction on inflammatory reactions and oxidative stress were evaluated by detecting interleukin-4(IL-4),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),transforming growth factorβ(TGF-β),total antioxidative capacity(T-AOC),malondialdehyde(MDA),superoxide dismutase(SOD),and catalase(CAT)levels.Results:After treatment with Huanglian Jiedu Decoction,the ALD scores of AIS patients in both groups increased,while the NISHH scores decreased,suggesting that Huanglian Jiedu Decoction has therapeutic effects on AIS patients.It also reduces the levels of serum IL-6,TNF-α,MDA in AIS patients and increases the levels of IL-4,TGF-β,CAT,SOD,T-AOC,suggesting that Huanglian Jiedu decoction can improve the anti-inflammatory and antioxidant abilities of AIS patients.Conclusion:Huanglian Jiedu decoction can help AIS patients recover their neurological function,increase their capacity for self-care in daily life,and strengthen the body’s anti-inflammatory and antioxidant defenses.

Characteristic metabolic and microbial profiles in acute ischemic stroke patients with phlegm-heat pattern

Objective:To explore the characteristics of plasma metabolites,feces gut microbiota and the crosstalk between gut microbiota and host metabolism in patients with acute ischemic stroke and phlegm-heat pattern(AIS-PHP).Methods:The metabolic and microbiome profiles of 20 AIS-PHP patients and 20 healthy controls(HCs)were analyzed using liquid chromatography-tandem mass spectrometry(LC-MS/MS)-based metabolomics and 16s rDNA sequencing,respectively.The covariation between LC-MS/MS-based metabolite data and 16s rDNA sequence data was presented.Results:Distinct alterations in the plasma metabolic phenotype of AIS-PHP patients were found,in which 16 metabolites differed significantly between the AIS-PHP patients and the HCs.These metabolites represented 17 different metabolic pathways,including amino acid metabolism,lipid metabolism,and nucleotide metabolism.Additionally,significant alterations of gut microbiota composition and taxon were revealed at the phylum level between the AIS-PHP patients and the HCs.In AIS-PHP,Bacteroidetes,Firmicutes,and Proteobacteria dominated.Moreover,some microbes that differed between the 2 groups manifested a sole association with certain metabolites,such as the connection between Bacteroides and inosine and between Lachnospiraceae_unclassified and hypoxanthine.Conclusion:The present study preliminarily investigated the metabolomic and gut microbiome characteristics of AIS-PHP patient indicators.The link between metabolic and microbial dysbiosis in AIS-PHP sheds new light on the function of gut microbiota and associated metabolomics in the pathogenesis of the disease.

Image-based visualization of stents in mechanical thrombectomy for acute ischemic stroke:Preliminary findings from a series of cases

BACKGROUND Mechanical thrombectomy is the most effective treatment for great cerebral artery embolization within a set time window.Typically,an arteriogram does not show the localization of the stent after release and whether a thrombus is captured or not.Thus,improving the visualization of a stent in interventional therapy will be helpful for clinicians.AIM To analyze stent imaging findings to enhance clinicians’understanding of a special circumstance,wherein a Solitaire AB retrievable stent was visible during the imaging of a thrombus capture that improved the success rate of stent-based mechanical thrombectomy.METHODS This was a retrospective study with four acute ischemic stroke(AIS)patients who underwent stent-based mechanical thrombectomy.RESULTS Patient 1 was a 64-year-old man admitted after 5 h of confusion;angiography revealed basilar artery occlusion.We inserted a stent into the left posterior cerebral artery-P2 segment and visualized the expanded stent that successfully captured a thrombus.Patient 2 was a 74-year-old man admitted with confusion,which lasted approximately 3 h.Angiography revealed a left middle cerebral artery(MCA)-M1 segment occlusion.A stent was deployed in the distal M2 segment,and we could visualize the stent by capturing the thrombus.Patient 3 was a 74-year-old woman admitted after experiencing left hemiplegia for 3 h.We deployed a stent at the distal right MCAM2 segment,and the developing stent captured a large thrombus.Patient 4 was an 82-year-old man who presented with confusion for 3 h.A developing stent was placed in the distal left MCA-M1 segment,which captured a large thrombus and several fragmented thrombi.CONCLUSION To the best of our knowledge,this is the first report of stent imaging in patients with AIS.We demonstrated the usefulness and substantial potential of stent imaging in stent-based mechanical thrombectomy for AIS.

Early intravenous administration of tirofiban is recommended in patients with acute ischemic stroke treated with alteplase:a meta-analysis

Background:The occurrence of early neurological deterioration following intravenous thrombolysis(IVT)is considered a particularly ominous clinical event and is strongly correlated with poor outcomes.Initiating tirofiban within 24 h after IVT has been suggested as a better treatment option to achieve long-term functional outcomes.However,the rationality of this remedy is a controversial.The purpose of the study was to evaluate the safety and efficacy of early intravenous tirofiban administration after IVT in patients with acute ischemic stroke(AIS).Methods:Databases including PubMed,EMBASE,Cochrane Library,and Web of Science were searched for clinical trials on early tirofiban implementation after IVT in patients with AIS from inception to September 2022.Odds ratios(ORs)were generated for dichotomous variants via meta-analysis using STATA 17.0 MP.Results:Five clinical trials with 725 patients were eligible.The study outcomes demonstrated that early tirofiban administration after IVT was not associated with symptomatic intracranial hemorrhage(OR,0.78;95%confidence interval(CI),0.22–2.74;P=0.70),asymptomatic intracranial hemorrhage(OR,1.11;95%CI,0.52–2.37;P=0.80),systemic bleeding(OR,0.97;95%CI,0.42–2.23;P=0.94),and death(OR,1.05;95%CI,0.47–2.31;P=0.91),but may reduce the incidence of early neurological deterioration(OR,0.09;95%CI,0.02–0.50;P=0.01),and was significantly associated with 90-day excellent(modified Rankin scale score 0–1)(OR,2.01;95%CI,1.35–3.02;P=0.00)and favorable(modified Rankin scale score 0–2)(OR,2.30;95%CI,1.63–3.23;P=0.00)functional outcomes.Conclusion:The early intravenous administration of tirofiban after IVT in patients with AIS may be a safe and effective treatment strategy that improves long-term neurological functional outcomes without increasing the risk of adverse events.

Different strategies for ultra-early reperfusion therapy in anterior circulation acute ischemic stroke safety and effectiveness of the comparative observation

Background:To compare the safety and effectiveness of direct mechanical thrombectomy and bridging therapy for stroke with acute anterior circulation large vessel occlusion within 4.5 hours of onset.Methods:Retrospectively collected from 66 patients with acute ischemic stroke admitted to the Department of Neurology of Tongliao Hospital and Xuanwu Hospital from August 2019 to November 2021 within 4.5 hours.According to the different recanalization methods,30 patients were assigned to the direct thrombectomy treatment group,and 36 patients in the bridging treatment group(i.e.,the intravenous thrombolysis bridging mechanical thrombectomy treatment group).The primary outcome measure was the neurological outcome at the onset of 90d.Secondary outcome measures were intraoperative vascular recanalization and reperfusion,and the US National Institute of Health Stroke Scale score at 24 hours after surgery.The primary safety indicators are intracranial hemorrhage,including symptomatic intracranial hemorrhage and non-symptomatic intracranial hemorrhage,and 90d mortality.Results:The direct thrombectomy group had lower body mass index,hypertension and baseline Alberta early computed tomography score than the bridging treatment group,and longer time from onset to visit than the bridging group(206.5(119.5,256.25)min vs.150.5(25.205,212.75)min),the above difference were statistically significant(P<0.05).There were no significant differences in successful vascular reperfusion(93%vs.89%),24 hours postoperative National Institute of Health Stroke Scale score(11(5,18)vs.11(5,20)),intracranial hemorrhage(11%vs.14%),symptomatic intracranial hemorrhage(7%vs.17%),90d mRS0 to 2 points(43%vs.36%)and 90d mortality(23%vs.22%)(P>0.05).Conclusion:Similar clinical efficacy and safety of direct mechanical thrombectomy and bridging therapy for acute anterior circulation large vessel occlusive stroke within 4.5 hours of onset,direct thrombectomy can be used as an alternative scheme for acute anterior circulation intracranial large artery occlusive stroke.

Immediate effects of scalp acupuncture with twirling reinforcing manipulation on hemiplegia following acute ischemic stroke: a hidden association study

Data mining has the potential to provide information for improving clinical acupuncture strategies by uncovering hidden rules between acupuncture manipulation and therapeutic effects in a data set. In this study, we performed acupuncture on 30 patients with hemiplegia due to acute ischemic stroke. All participants were pre-screened to ensure that they exhibited immediate responses to acupuncture. We used a twirling reinforcing acupuncture manipulation at the specific lines between the bilateral Baihui（GV20） and Taiyang（EX-HN5）. We collected neurologic deficit score, simplified Fugl-Meyer assessment score, muscle strength of the proximal and distal hemiplegic limbs, ratio of the maximal H-reflex to the maximal M-wave（Hmax/Mmax）, muscle tension at baseline and immediately after treatment, and the syndromes of traditional Chinese medicine at baseline. We then conducted data mining using an association algorithm and an artificial neural network backpropagation algorithm. We found that the twirling reinforcing manipulation had no obvious therapeutic difference in traditional Chinese medicine syndromes of ＂Deficiency and Excess＂. The change in the muscle strength of the upper distal and lower proximal limbs was one of the main factors affecting the immediate change in Fugl-Meyer scores. Additionally, we found a positive correlation between the muscle tension change of the upper limb and Hmax/Mmax immediate change, and both positive and negative correlations existed between the muscle tension change of the lower limb and immediate Hmax/Mmax change. Additionally, when the difference value of muscle tension for the upper and lower limbs was 〉 0 or 〈 0, the difference value of Hmax/Mmax was correspondingly positive or negative, indicating the scalp acupuncture has a bidirectional effect on muscle tension in hemiplegic limbs. Therefore, acupuncture with twirling reinforcing manipulation has distinct effects on acute ischemic stroke patients with different symptoms or stages of disease. Improved muscle tension in the upper and lower limbs, reflected by the variation in the Hmax/Mmax ratio, is crucial for recovery of motor function from hemiplegia.

Xingnao Kaiqiao needling method for acute ischemic stroke： a meta-analysis of safety and efficacy

OBJECTIVE： To evaluate the effectiveness and safety of the Xingnao Kaiqiao needling method for treating acute ischemic stroke.DATA SOURCES： We retrieved relevant randomized controlled trials involving Xingnao Kaiqiao acupuncture for treatment of acute ischemic stroke. The China National Knowledge Infrastructure, Weipu Information Resources System, Wanfang Medical Data System, Chinese Biomedical Literature Database, Cochrane Library, and Pub Med were searched from June 2006 to March 2016.DATA SELECTION： We analyzed randomized and semi-randomized clinical controlled trials that compared Xingnao Kaiqiao acupuncture with various control treatments, such as conventional drugs or other acupuncture therapies, for treatment of acute ischemic stroke. The quality of articles was evaluated according to the Cochrane Handbook for Systematic Reviews of Interventions（Version 5.1）, and the study was carried out using Cochrane system assessment methods. Rev Man 5.2 was used for the meta-analysis of the included studies.OUTCOME MEASURES： The mortality rate, disability rate, activities of daily living（Barthel Index）, and clinical efficacy were observed.RESULTS： Twelve studies met the inclusion criteria for this review. The meta-analysis showed that between Xingnao Kaiqiao acupuncture and the control treatment, Xingnao Kaiqiao acupuncture reduced the disability rate [risk ratio（RR） = 0.51, 95% confidence interval（CI） = 0.27-0.98, z = 2.03, P 〈 0.05], elevated the activities of daily living（weighted mean difference = 12.23, 95% CI： 3.66-20.08, z = 2.80, P 〈 0.005）, and had greater clinical efficacy（RR = 1.61, 95% CI： 1.23-2.09, z = 3.53, P 〈 0.0004）. However, there was no significant difference in mortality rate（RR = 0.61, 95% CI： 0.15-2.45, z = 0.70, P 〉 0.05）. CONCLUSION： The Xingnao Kaiqiao needling method is effective and safe for acute ischemic stroke. However, there was selective bias in this study, and the likelihood of measurement bias is high. Thus, more high-quality randomized controlled trials are needed to provide reliable evidence of the efficacy and safety of Xingnao Kaiqiao acupuncture in the treatment of acute ischemic stroke.

Hyperglycemia in acute ischemic stroke: physiopathological and therapeutic complexity

Diabetes mellitus and associated chronic hyperglycemia enhance the risk of acute ischemic stroke and lead to worsened clinical outcome and increased mortality. However, post-stroke hyperglycemia is also present in a number of non-diabetic patients after acute ischemic stroke, presumably as a stress response. The aim of this review is to summarize the main effects of hyperglycemia when associated to ischemic injury in acute stroke patients, highlighting the clinical and neurological outcomes in these conditions and after the administration of the currently approved pharmacological treatment, i.e. insulin. The disappointing results of the clinical trials on insulin(including the hypoglycemic events) demand a change of strategy based on more focused therapies. Starting from the comprehensive evaluation of the physiopathological alterations occurring in the ischemic brain during hyperglycemic conditions, the effects of various classes of glucose-lowering drugs are reviewed, such as glucose-like peptide-1 receptor agonists, DPP-4 inhibitors and sodium glucose cotransporter 2 inhibitors, in the perspective of overcoming the up-to-date limitations and of evaluating the effectiveness of new potential therapeutic strategies.

Maternal dietary deficiencies in folic acid or choline worsen stroke outcomes in adult male and female mouse offspring

Maternal one-carbon metabolism plays an important role in early life programming.There is a well-established connection between the fetal environment and the health status of the offspring.Howeve r,there is a knowledge gap on how maternal nutrition impacts stro ke outcomes in offspring.The aim of our study was to investigate the role of maternal dietary deficiencies in folic acid or choline on stroke outcomes in 3-month-old offspring.Adult female mice were fed a folic acid-deficient diet,choline-deficient diet,or control diet 4 weeks before pregnancy.They we re continued on diets during pregnancy and la ctation.Male and female offspring were weaned onto a control diet and at 2 months of age were subjected to ischemic stroke within the sensorimotor cortex via photothrombotic damage.Mothers maintained on either a folic acid-deficient diet or choline-deficient diet had reduced levels of S-adenosylm ethionine in the liver and S-adenosylhomocysteine in the plasma.After ischemic stro ke,motor function was impaired in 3-month-old offspring from mothers receiving either a folic acid-deficient diet or choline-deficient diet compared to the animals receiving a control diet.In brain tissue,there was no difference in ischemic damage volume.When protein levels were assessed in ischemic brain tissue,there were lower levels of active caspase-3 and hypoxia-inducible factor 1α in males compared to females and betaine levels were reduced in offspring from the mothers receiving a choline-deficient diet.Our results demonstrate that a deficient maternal diet at critical time points in neurodevelopment results in worse stro ke outcomes.This study emphasizes the importance of maternal diet and the impact it can have on offspring health.

Efficacy and safety of argatroban in treatment of acute ischemic stroke:A meta-analysis

BACKGROUND Argatroban is a novel direct thrombin inhibitor that has been used for treatment of acute ischemic stroke(AIS).To our knowledge,no systematic analysis has assessed the efficacy and safety of argatroban for treatment of AIS.AIM To evaluate the efficacy and safety of argatroban for treatment of AIS.METHODS Cochrane Library,Medline,PubMed,and Web of Science were searched to retrieve all studies associated with argatroban and AIS.Effective rate,adverse events rate,and 95%confidence intervals were calculated and pooled using metaanalysis methodology.RESULTS We only found four randomized controlled studies,comprising 354 cases with 213 in the argatroban group and 141 in the control group.Great heterogeneity was found in the four studies(c2=11.44,I2=74%,P=0.01).Subgroup analysis could not be performed because of the absence of detailed data.The two most recent studies showed acceptable heterogeneity(c2=1.56,I2=36%,P=0.21).Our analysis showed that argatroban was not more effective than the control therapy in the acute phase of ischemic stroke(Z=0.01,P=0.99).Argatroban did not increase the risk of bleeding compared with the control group(c2=0.37,I2=0%,P=0.54,Z=0.80,P=0.42).CONCLUSION Patients with AIS might not benefit from argatroban and combination therapy with argatroban does not increase bleeding tendency.

Factors influencing clinical outcomes of acute ischemic stroke treated with intravenous recombinant tissue plasminogen activator

Background Thrombolysis with recombinant tissue plasminogen activator （rt-PA） has gained international recognition, clinical outcomes following this thrombolytic therapy varied from patient to patient. Factors affecting clinical outcomes have not been well understood yet, so this retrospective case-control study aimed to investigate factors that may influence clinical outcomes of acute ischemic stroke treated with intravenous rt-PA. Methods One hundred and one patients with acute ischemic stroke who received intravenous rt-PA thrombolysis within 4.5 hours from disease onset were included. Patients were divided into good or poor outcome group according to modified Rankin Scale （mRS） score, good outcome group： mRS score of 0-1; poor outcome group： mRS of 2-6. Stroke characteristics were compared between the two groups. Factors for stroke outcomes were analyzed via univariate analysis and Logistic regression. Results Of the 101 patients studied, patients in good outcome group （n=55） were significantly younger than patients in poor outcome group （n=46, （62.82±14.25） vs. （68.81±9.85） years, P=0.029）. Good outcome group had fewer patients with diabetic history （9.09% vs. 28.26%, P=0.012）, fewer patients with leukoaraiosis （7.27% vs. 28.26%, P=-0.005） and presented with lower blood glucose level （（5.72±1.76） vs. （6.72±1.32） mmol/L, P=0.012）, lower systolic blood pressure level （（135.45±19.36） vs. （148.78±19.39） mmHg, P=0.003）, lower baseline NIHSS score （12.02±5.26 vs. 15.78±4.98, P=0.002） and shorter onset-to-treatment time （OTT） （（2.38±1.21） vs. （2.57±1.03） hours, P=0.044） than poor outcome group. Logistic regression analysis showed that absence of diabetic history （odds ratio （OR） 0.968 （95% CI 0.941-0.996））, absence of leukoaraiosis （OR 0.835 （95% C/0.712-0.980））, lower baseline NIHSS score （OR 0.885 （95% Cl 0.793- 0.989））, lower pre-thrombolysis systolic blood pressure （OR 0.962 （95% CI 0.929-0.997））, and lower blood glucose level （OR 0.699 （95% Cl 0.491-0.994）） before thrombolysis were significantly associated with better outcome. Conclusion Patients with no history of diabetes, no leukoaraiosis, low blood glucose level, low systolic blood pressure level and low baseline NIHSS score before thrombolvsis have a better outcome.
