The aim of the present study was to assess a FVH score and explore its relationship with clinical outcomes. Patients with acute ischemic stroke due to middle cerebral artery M1 occlusion underwent magnetic resonance imaging and were followed up at 10 days （National Institutes of Health Stroke Scale） and 90 days （modified Rankin Scale） to determine short-term clinical outcomes. Effective collateral circulation indirectly improved recovery of neurological function and short-term clinical outcome by extending the size of the pial penumbra and reducing infarct lesions. FVH score showed no correlation with 90-day functional clinical outcome and was not sufficient as an independent predictor of short-term clinical outcome.展开更多

Compared with the control group, the clinical total effective rate and the cortical potential rise rate of the upper limbs were significantly higher, the central motor conduction time of upper limb was significantly shorter, and the upper limb motor-evoked potential amplitude was significantly increased, in the ozone group. In the ozone group, the National Institutes of Health Stroke Score was positively correlated with the central motor conduction time and the motor-evoked potential amplitude of the upper limb. Central motor conduction time and motor-evoked potential amplitude of the upper limb may be effective indicators of motor-evoked potentials to assess upper limb motor function in cerebral infarct patients. Furthermore, major ozonated autohemotherapy may promote motor function recovery of the upper limb in patients with acute cerebral infarction.展开更多

In this study, we sought to explore clinical characteristics of its substypes and biomarkers for prognosis of BAD. A total of 176 consecutive patients with BAD were classified into two groups： paramedianpontine artery group（PPA group, n=70） and lenticulostriate artery group（LSA group, n=106）. Bivariate analyses were used to explore the relationship between white matter hyperintensities（WMHs）, National Institutes of Health Stroke Scale（NIHSS） scores and prognosis evaluated by the modified Rank Scale（m RS） at 6th month after stroke. The differences in prevalence of diabetes mellitus and a history of ischemic heart disease were statistically significant between PPA group and LSA group（χ~2=8.255, P=0.004; χ~2=13.402, P〈0.001）. The bivariate analyses demonstrated a positive correlation between NIHSS and poor prognosis in patients with BAD and in the two subtype groups, and a positive correlation between WMHs and poor prognosis in the PPA group. It is concluded that a significantly higher prevalence of diabetes mellitus and a history of ischemic heart disease exist in the PPA group than in the LSA group. In addition, high grades of NIHSS scores imply poor prognosis in patients with BAD and in the two subtype groups. Moreover, WMHs are a positive predictor for poor prognosis in patients in the PPA group.展开更多

文摘Cerebral blood perfusion and cerebrovascular lesions are important factors that can affect the therapeutic efficacy of thrombolysis.At present,the majority of studies focus on assessing the accuracy of lesion location using imaging methods before treatment,with less attention to predictions of outcomes after thrombolysis.Thus,in the present study,we assessed the efficacy of combined computed tomography（CT） perfusion and CT angiography in predicting clinical outcomes after thrombolysis in ischemic stroke patients.The study included 52 patients who received both CT perfusion and CT angiography.Patients were grouped based on the following criteria to compare clinical outcomes：（1） thrombolytic and non-thrombolytic patients,（2） thrombolytic patients with CT angiography showing the presence or absence of a vascular stenosis,（3） thrombolytic patients with CT perfusion showing the presence or absence of hemodynamic mismatch,and（4） different CT angiography and CT perfusion results.Short-term outcome was assessed by the 24-hour National Institution of Health Stroke Scale score change.Long-term outcome was assessed by the 3-month modified Rankin Scale score.Of 52 ischemic stroke patients,29 were treated with thrombolysis and exhibited improved short-term outcomes compared with those without thrombolysis treatment（23 patients）.Patients with both vascular stenosis and blood flow mismatch（13 patients） exhibited the best short-term outcome,while there was no correlation of long-term outcome with CT angiography or CT perfusion findings.These data suggest that combined CT perfusion and CT angiography are useful for predicting short-term outcome,but not long-term outcome,after thrombolysis.

文摘Cattle encephalon glycoside and ignotin(CEGI)injection is a compound preparation formed by a combination of muscle extract from hea lthy rabbits and brain gangliosides from cattle,and it is generally used as a neuroprotectant in the treatment of central and peripheral nerve injuries.However,there is still a need for high-level clinical evidence from large samples to support the use of CEGI.We therefore carried out a prospective,multicenter,randomized,double-blind,parallel-group,placebo-controlled study in which we recruited 319 patients with acute cerebral infarction from 16 centers in China from October 2013 to May 2016.The patients were randomized at a 3:1 ratio into CEGI(n=239;155 male,84 female;61.2±9.2 years old)and placebo(n=80;46 male,34 female;63.2±8.28 years old)groups.All patients were given standard care once daily for 14 days,including a 200 mg aspirin enteric-coated tablet and 20 mg atorvastatin calcium,both taken orally,and intravenous infusion of 250–500 mL 0.9%sodium chloride containing 40 mg sodium tanshinone IIA sulfonate.Based on conventional treatment,patients in the CEGI and placebo groups were given 12 mL CEGI or 12 mL sterile water,respectively,in an intravenous drip of 250 mL 0.9%sodium chloride(2 mL/min)once daily for 14 days.According to baseline National Institutes of Health Stroke Scale scores,patients in the two groups were divided into mild and moderate subgroups.Based on the modified Rankin Scale results,the rate of patients with good outcomes in the CEGI group was higher than that in the placebo group,and the rate of disability in the CEGI group was lower than that in the placebo group on day 90 after treatment.In the CEGI group,neurological deficits were decreased on days 14 and 90 after treatment,as measured by the National Institutes of Health Stroke Scale and the Barthel Index.Subgroup analysis revealed that CEGI led to more significant improvements in moderate stroke patients.No drug-related adverse events occurred in the CEGI or placebo groups.In conclusion,CEGI may be a safe and effective treatment for acute cerebral infarction patients,especially for moderate stroke patients.This study was approved by the Ethical Committee of Peking University Third Hospital,China(approval No.2013-068-2)on May 20,2013,and registered in the Chinese Clinical Trial Registry(registration No.ChiCTR1800017937).

文摘Major ozonated autohemotherapy is classically used in treating ischemic disorder of the lower limbs In the present study, we performed major ozonated autohemotherapy treatment in patients with acute cerebral infarction, and assessed outcomes according to the U.S. National Institutes of Health Stroke Score, Modified Rankin Scale, and transcranial magnetic stimulation motor-evoked potential. Compared with the control group, the clinical total effective rate and the cortical potential rise rate of the upper limbs were significantly higher, the central motor conduction time of upper limb was significantly shorter, and the upper limb motor-evoked potential amplitude was significantly increased, in the ozone group. In the ozone group, the National Institutes of Health Stroke Score was positively correlated with the central motor conduction time and the motor-evoked potential amplitude of the upper limb. Central motor conduction time and motor-evoked potential amplitude of the upper limb may be effective indicators of motor-evoked potentials to assess upper limb motor function in cerebral infarct patients. Furthermore, major ozonated autohemotherapy may promote motor function recovery of the upper limb in patients with acute cerebral infarction.

文摘Leukoaraiosis(LA)results from ischemic injury in small cerebral vessels,which may be attributable to decreased vascular density,reduced cerebrovascular angiogenesis,decreased cerebral blood flow,or microcirculatory dysfunction in the brain.In this study,we enrolled 357 patients with mild intracerebral hemorrhage(ICH)from five hospitals in China and analyzed the relationships between LA and clinical symptom severity at admission,neurological function prognosis at 3 months,and 1-year stroke recurrence.Patients were divided into groups based on Fazekas scale scores:no LA(n=83),mild LA(n=64),moderate LA(n=98)and severe LA(n=112).More severe LA,larger hematoma volume,and higher blood glucose level at admission were associated with more severe neurological deficit.More severe LA,older age and larger hematoma volume were associated with worse neurological function prognosis at 3 months.In addition,moderate-to-severe LA,admission glucose and symptom-free cerebral infarction were associated with 1-year stroke recurrence.These findings suggest that LA severity may be a potential marker of individual ICH vulnerability,which can be characterized by poor tolerance to intracerebral attack or poor recovery ability after ICH.Evaluating LA severity in patients with mild ICH may help neurologists to optimize treatment protocols.This study was approved by the Ethics Committee of Ruijin Hospital Affiliated to Shanghai Jiao Tong University(approval No.12)on March 10,2011.
文摘The theory of branch atheromatous disease（BAD） has been commonly underused in clinical practice and research since it was proposed in 1989. In this study, we sought to explore clinical characteristics of its substypes and biomarkers for prognosis of BAD. A total of 176 consecutive patients with BAD were classified into two groups： paramedianpontine artery group（PPA group, n=70） and lenticulostriate artery group（LSA group, n=106）. Bivariate analyses were used to explore the relationship between white matter hyperintensities（WMHs）, National Institutes of Health Stroke Scale（NIHSS） scores and prognosis evaluated by the modified Rank Scale（m RS） at 6th month after stroke. The differences in prevalence of diabetes mellitus and a history of ischemic heart disease were statistically significant between PPA group and LSA group（χ~2=8.255, P=0.004; χ~2=13.402, P〈0.001）. The bivariate analyses demonstrated a positive correlation between NIHSS and poor prognosis in patients with BAD and in the two subtype groups, and a positive correlation between WMHs and poor prognosis in the PPA group. It is concluded that a significantly higher prevalence of diabetes mellitus and a history of ischemic heart disease exist in the PPA group than in the LSA group. In addition, high grades of NIHSS scores imply poor prognosis in patients with BAD and in the two subtype groups. Moreover, WMHs are a positive predictor for poor prognosis in patients in the PPA group.

文摘BACKGROUND In a previous study,basilar artery occlusion(BAO)was shown to lead to death or disability in 80%of the patients.The treatment for BAO patients in the acute stage includes thrombolysis and intra-arterial thrombectomy,but not all patients benefit from these treatments.Thus,understanding the predictors of outcome before initiating these treatments is of special interest.AIM To determine the predictors related to the 90-d clinical outcome in patients with BAO in an Asian population.METHODS We performed a retrospective case review of patients admitted to a tertiary stroke center between 2015 and 2019.We used the international classification of diseases-10 criteria to identify cases of posterior circulation stroke.A neurologist reviewed every case,and patients fulfilling the criteria defined in the Basilar Artery International Cooperation Study were included.We then analyzed the patients’characteristics and factors related to the 90-d outcome.RESULTS We identified a total of 99 patients as real BAO cases.Of these patients,33(33.3%)had a favorable outcome at 90 d(modified Rankin Scale:0–3).Moreover,72 patients received intra-arterial thrombectomy,while 13 patients received intravenous tissue-type plasminogen activator treatment.We observed a favorable outcome in 33.3%of the cases and an unfavorable outcome in 66.7%of the cases.We found that the initial National Institutes of Health Stroke Scale(NIHSS)score and several BAO symptoms,including impaired consciousness,tetraparesis,and pupillary abnormalities,were significantly associated with an unfavorable outcome(P<0.05),while cerebellar symptoms were associated with a favorable outcome(P<0.05).In the receiver operating characteristic(ROC)analysis,the areas under the ROC curve of initial NIHSS score,impaired consciousness,tetraparesis,cerebellar symptoms,and pupillary abnormalities were 0.836,0.644,0.727,0.614,and 0.614,respectively.Initial NIHSS score showed a higher AUROC(0.836)compared to BAO symptoms.CONCLUSION The most important predictor of an unfavorable outcome was the initial NIHSS score.BAO symptoms,including tetraparesis,impaired consciousness,and pupillary abnormality were also related to an unfavorable outcome.
文摘目的探讨颅内动脉狭窄、血压变异性与急性缺血性脑卒中(AIS)患者神经功能及预后的关系。方法回顾性分析2018年1月—2021年1月收治的AIS 152例的临床资料。根据是否发生早期神经功能恶化(END)分为END组(n=45)和非END组(n=107)。根据卒中发病后90 d的预后情况分为预后良好组(n=60)和预后不良组(n=92)。评估颅内动脉狭窄程度,监测24 h动态血压,计算收缩压标准差(SSD)、舒张压标准差(DSD)。分析影响患者预后的危险因素。结果END组颅内动脉总狭窄率高于非END组,且END组颅内动脉狭窄程度更严重(P<0.05,P<0.01)。END组24 h SSD、24 h DSD、日间SSD、日间DSD、夜间SSD、夜间DSD均高于非END组(P<0.05,P<0.01)。END组杓型血压节律的比例低于非END组,而非杓型血压节律的比例高于非END组(P<0.05,P<0.01)。颅内动脉中、重度狭窄及入院时美国国立卫生研究院卒中量表评分>12分、24 h SSD>12 mmHg、发生END是导致AIS患者预后不良的危险因素,而杓型血压节律为保护性因素(P<0.05,P<0.01)。结论颅内动脉狭窄程度、血压变异性与AIS患者神经功能有关,且是预后的影响因素。
