A large amount of research evidence has shown a correlation between cerebral infarction and malignant tumors, and malignant-tumor-related embolic stroke is the main type of malignant-tumor-related cerebral infarction. Hypercoagulation is considered to be the main mechanism. However, due to the complexity of the pathogenesis, the optimal diagnosis, treatment, and prevention strategies remain unclear. This review summarizes the published literature on the concepts, mechanisms, clinical manifestations, laboratory and imaging examinations, treatment and prevention of malignant-tumor-related embolic cerebral infarction, to clearly understand this disease and provide ideas for early recognition, reasonable diagnosis and treatment, improvement of prognosis, and further research of this disease.
Objective To discuss the optimal time for operation in patients with malignant middle cerebral artery (MCA) syndrome. Method The relation between effectiveness and operating time was analyzed in 47 patients to compare the effects of early and delayed operation by SPSS10.0. Results Among 27 patients undergoing early operation, 18 were cured or restored, 4 seriously disabled and 5 died. While among 20 patients undergoing delayed operation, only 9 were cured or restored, 4 seriously disabled and 7 died. The prognosis of delayed operation group was worse than that of early operation group. Conclusions Selecting the optimal time to operate may decrease the mortality and morbidity of MCA syndrome.
Objective To systematically review the relationship between helicobacter pyloric (HP) infection and ischemia stroke. Methods We searched MEDLINE, BIOSIS, VIP, and China Full Text Journal databases to identify the studies that studied the relationship between HP infection and ischemia stroke. All the studies were strictly screened according to the inclusion criteria, and meta-analyses were performed for the included studies using RevMan 4.2 software.Results Eleven case-control studies involving 1 530 patients with ischemia stroke and 1 451 health controls were included. The results of meta-analyses showed that there was a significant difference in the infection ratio of HP between the patients with ischemia stroke and health controls (OR=1.77, 95%CI 1.38 to 2.28, Plt;0.0001), but this difference was not been found after adjusting some related risk factors (1.22, 95%CI 0.93 to 1.59, P=0.15). The results of subgroup meta-analyses showed these differences were only found in the LAA (large-artery atherosclerosis) subgroup (OR=3.65, 95%CI 2.58 to 5.17) and the SAA (small-artery atherosclerosis) subgroup (OR=1.74, 95%CI 1.30 to 2.34), but was not found in the CE (cardiogenic cerebral embolism) subgroup (OR=1.08, 95%CI 0.58 to 2.02). Conclusion HP infection is associated with ischemia stroke, but the relationships between HP infection and the subtypes of ischemia stroke are different. The association between HP and LAA is ber than that between HP and the other subtypes. More evidence is needed to prove whether Helicobacter pyloric infection is an independent risk factor of ischemia stroke.
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.
Objective To assess the clinical efficacy and safety of Xingnaojing for treating cerebral infarction. Methods Randomized controlled trials (RCTs) were identified from MEDLINE (1966 to April 2005), EMBASE (1984 to April 2005), Cochrane Controlled Trials Register (Issue 2, 2005), CBMdisc (1978 to April 2005). We handsearched the related published and unpublished data and their references. All trials about Xingnaojing injection for cerebral infarction were included. Data were extracted and evaluated by two reviewers independently with designed extraction from RevMan 4.2.7 software was used for data analysis. Results Thirteen RCTs involving 1203 patients were include .The results of meta-analysis were listed as the following:①Mortality:Compared with danshen ,2 studies showed that Xingnaojing decreased mortality statistically (RR 0.31 and 95% CI 0.14 to 0.70).Compared with cerebrolysin ,1 study showed Xingnaojing didn’t decrease the mortality (RR 0.92 ,95%CI 0.14 to 6.27);②Total effective rate: Compared with Danshen ,4 studies showed that Xingnaojing were more effective (RR 0.92,95% CI 1.12 to 1.42 ); ③ Cure rate: Compared with each control , Xingnaojing had the same cure rate ;④ Adverse effect: The number of adverse drug reaction was small and the symptoms were moderate;⑤Neurologic impairment score:Compared with Danshen ,3 studies showed that Xingnaojing had better improvement (WMD 3.78 ,95%CI 2.30 to 5.26).Conclusions xingnaojing may decrease the mortality and increase the total effective rate of cerebral infarction .More high quality trials are required.
ObjectiveTo explore the feasibility and effectiveness of community-based rehabilitation for patients with cerebral infarction.
MethodThe cerebral infarction patients (n=285) registered before March 2011 and newly involved in the research between March 2011 and September 2012 were randomly divided into rehabilitation group (n=142) and control group (n=143). The doctors in community hospitals were trained by specialist physicians in Neurology Department and Rehabilitation Department from second-grade hospitals. Community physicians were responsible for the patients' rehabilitation for one year.
ResultsNo differences between the rehabilitation group and the control group in the time of enrollment situation (P>0.05). After six months of intervention, there were significant differences between the two groups of patients in neurological function, daily activity ability, anxiety and depression scale scores (P<0.05), and the difference was more significant after 12 months (P<0.01). The results of Kubota drinking experiment were significantly different between the two groups after six months of intervention (P<0.05).
ConclusionsCommunity-based rehabilitation treatment can significantly reduce the degree of physical and mental disability. The cooperation between second-grade hospitals and community hospitals is an effective way to realize three-stage neurological rehabilitation, which can better improve patients' quality of life and is helpful for them return to the society.
ObjectiveTo explore the relationship between plasma homocysteine level and intracranial artery atherosclerosis in patients with cerebral infarction.
MethodsA total of 120 patients with cerebral infarction diagnosed between January and December 2013 were selected.Plasma homocysteine level was analyzed and intracranial artery was detected by DSA.
ResultsIntracranial artery atherosclerosis can be found in most of patients with cerebral infarction.Moreover,Plasma Hcy level of patients with large cerebral artery atherosclerosis was much higher than others (P<0.05).The much higher Plasma Hcy level,the severe intracranial artery atherosclerosis were found in internal carotid artery and cerebral middle artery (P<0.05).
ConclusionIntracranial artery atherosclerosis is common in patients with cerebral infarction.Occurrence of intracranial artery atherosclerosis is positively correlated with plasma homocysteine level.Plasma homocysteine level may be a risk factor of intracranial artery atherosclerosis in patients with cerebral infarction.
Objective To summarize cl inical experience of carotid endarterectomy (CEA) in treating severe carotid stenosis. Methods Between October 1998 and January 2010, 215 patients with carotid stenosis were treated with CEA. There were 140 males and 75 females with an average age of 66 years (range, 51-88 years). Transient ischemic attack (TIA) occurred in127 cases, and 31 cases had history of cerebral infarction. All cases were diagnosed definitely by selective angiography and/or CT angiography, and stenosis degree was more than 80%; contralateral carotid artery was also involved in 45 cases. Ninty-six cases were found to have coronary artery stenosis by coronary angiography. CEA and coronary artery bypass grafting were performed simultaneously in 25 cases. Peripheral arterial disease was found in 43 cases and treated at the same time. Results A total of 155 patients were followed up 6-72 months. The cl inical symptom significantly alleviated in 148 cases postoperatively. Two cases had compl ication of cerebral hemorrhage within 1 week postoperatively; one died and the other was resumed after the conservative treatment. One case had hypoglossal nerve injury. Four cases had injuring marginal mandibular branch of the facial nerve, and no special treatment was given. Restenosis was found in 25 patients, and the stenosis degree was less than 25%; moreover, the patients had no TIA. One case died of heart attack at 3 years of follow-up period. Conclusion CEA is an effective and safe method for treating severe carotid stenosis.
ObjectiveTo evaluate the usage status of drugs in the treatment of senile cerebral infarction in Xuanwu Hospital of Capital Medical University in 2011, and to provide references for rational usage of drugs for inpatients with senile cerebral infarction.
MethodsMedical records of the elderly (≥60 years old) inpatients with cerebral infarction in Xuanwu Hospital in 2011 were collected. ATC codes were used to standardize names of drug and classifications. Patients' general information, number of patients' used drugs, Defined Daily Doses (DDDs), and Drug Utilization Index (DUI) were calculated by using Microsoft Excel 2007 to evaluate the rationality of drugs usage.
ResultsA total of 430 patients were included. The average age was 70.61±7.29 years old. The average types of diseases were 5.39. The major combined disease was circulatory system disease, accounting for 42.45%. A total of 15 656 medication records were included, involving 243 kinds of drugs (including different administration routes). The average number of used drugs for each patient during the admission was 17.11. The top 5 drugs based on percentage of patients with drug use were Ginkgo Biloba Preparation (injection), clopidogrel (oral), prostaglandin E1 (injection), atorvastatin (oral) and cinepazide (injection). The top 5 drugs of DDDs were Ginkgo Biloba Preparation (injection), ipratropium bromide (inhalation), prostaglandin E1 (injection), folic acid (orla), and clopidogrel (oral). The top 5 drugs of DUI were vitamin B12 (injection), multi-vitamin (oral), nikethamide (injection), methylprednisolone (injection), and vitamin C (oral).
ConclusionFor therapeutic drugs used among the elderly patients with cerebral infarction in Xuanwu Hospital of Capital Medical University, the choice, dosage and administration route of medication are rational. However, the drugs with higher DUI are not related with major diseases, which indicates that we should pay attention to the irrational drug use of clinical application, so as to ensure safety, effectiveness and economy of drug application.
ObjectiveTo analyze the clinical characteristics, risk factors, treatment and prognosis of epilepsy secondary to cerebral infarction.MethodsThe clinical data of 109 patients with epilepsy secondary to cerebral infarction admitted to the Affiliated Central Hospital of Shandong First Medical University from October 2018 to February 2021 were retrospectively analyzed, including the location of cerebral infarction, seizure type, seizure time and antiepileptic treatment.Results3 426 patients with cerebral infarction were treated in the same period, and the incidence of epilepsy secondary to cerebral infarction was 3.18%. Among 109 patients with epilepsy secondary to cerebral infarction, 71 were male and 38 were female, the average age was (67.42 ± 28.58) years. Time of seizure after cerebral infarction: 67 cases (61.47%) were early onset epilepsy and 42 cases (42.47%) were late onset epilepsy. The infarct site: 63.30% (69 /109) in cortex, 11.93% (13/109) in subcortical area, and 24.77% (27/109) in lacunar infarction secondary epilepsy. 5 cases died, the fatality rate was 1.59%, of which 4 patients died of early onset epilepsy, status epilepticus, and 1 patient died of late onset epilepsy due to acute cerebral infarction.ConclusionsIn patients with epilepsy secondary to cerebral infarction, the cortex is the most common site of infarction; focal seizures are more than comprehensive seizures; status epilepticus often indicates poor prognosis, so timely antiepileptic treatment should be given to improve the prognosis.
