Although this is a common method for clinical treatment of cerebral infarction, whether it promotes the recovery of motor function remains controversial. Twenty patients with cerebral infarction combined with hemiparalysis were equally and randomly divided into a low frequency r TMS group and a control group. The patients in the low frequency r TMS group were given 1-Hz r TMS to the contralateral primary motor cortex with a stimulus intensity of 90% motor threshold, 30 minutes/day. The patients in the control group were given sham stimulation. After 14 days of treatment, clinical function scores(National Institute of Health Stroke Scale, Barthel Index, and Fugl-Meyer Assessment) improved significantly in the low frequency r TMS group, and the effects were better than that in the control group. We conclude that low frequency(1 Hz) r TMS for 14 days can help improve motor function after cerebral infarction.展开更多

However, there are few studies concerning the use of different frequencies of repetitive transcranial magnetic stimulation on the recovery of upper-limb motor function after cerebral infarction. We hypothesized that different frequencies of repetitive transcranial magnetic stimulation in patients with cerebral infarction would produce different effects on the recovery of upper-limb motor function. This study enrolled 127 patients with upper-limb dysfunction during the subacute phase of cerebral infarction. These patients were randomly assigned to three groups. The low-frequency group comprised 42 patients who were treated with 1 Hz repetitive transcranial magnetic stimulation on the contralateral hemisphere primary motor cortex(M1). The high-frequency group comprised 43 patients who were treated with 10 Hz repetitive transcranial magnetic stimulation on ipsilateral M1. Finally, the sham group comprised 42 patients who were treated with 10 Hz of false stimulation on ipsilateral M1. A total of 135 seconds of stimulation was applied in the sham group and high-frequency group. At 2 weeks after treatment, cortical latency of motor-evoked potentials and central motor conduction time were significantly lower compared with before treatment. Moreover, motor function scores were significantly improved. The above indices for the low- and high-frequency groups were significantly different compared with the sham group. However, there was no significant difference between the low- and high-frequency groups. The results show that low- and high-frequency repetitive transcranial magnetic stimulation can similarly improve upper-limb motor function in patients with cerebral infarction.展开更多

In this study, we investigated injury of the STT in patients with CPSP following cerebral infarction, using DTT. Five patients with CPSP following cerebral infarction and eight age-and sex-matched healthy control subjects were recruited for this study. STT was examined using DTT. Among DTT parameters of the affected STT, fractional anisotropy and tract volume were decreased by more than two standard deviations in two patients(patients 1 and 2) and three patients(patients 3, 4, and 5), respectively, compared with those of the control subjects, while mean diffusivity value was increased by more than two standard deviations in one patient(patient 2). Regarding DTT configuration, all affected STTs passed through adjacent part of the infarct and three STTs showed narrowing. These findings suggest that injury of the STT might be a pathogenetic etiology of CPSP in patients with cerebral infarction.展开更多

However,there are few reports on the influence of electro-acupuncture at the Du meridian on neural stem cell proliferation. OBJECTIVE:To observe the influence of electro-acupuncture at Ren and Du meridians on neural stem cell proliferation in the subventricular zone and altered signal transduction in cerebral ischemia rats. DESIGN,TIME AND SETTING:A randomized,controlled,animal experiment was performed at the Laboratory of Human Anatomy,Medical College of Sun Yat-sen University from May 2006 to February 2008. MATERIALS:Mouse anti-rat bromodeoxyuridine (BrdU) monoclonal antibody was provided by Sigma,USA; mouse anti-rat nestin monoclonal antibody and extracellular signal-regulated protein kinase (ERK) specific inhibitor PD98059 were provided by Calbiochem,Germany; acupuncture needle was provided by Suzhou Acupuncture Supplies,China. METHODS:A total of 126 rats were randomly assigned to four groups:model (n = 36),Du meridian (n = 36),Ren/Du meridian (n = 36),and Ren/Du meridian + PD98059 (n = 18). Rats in the Ren /Du meridian + PD98059 group were observed on days 7 (n = 6) and 14 (n = 12) after cerebral ischemia injury. Rats in the model,Du meridian,and Ren/Du meridian groups were observed on days 7,14,and 28 after cerebral ischemia injury,with 12 rats per group at each time point. Thread occlusion was used to establish middle cerebral artery occlusion models. Electro-acupuncture was performed at Renzhong (DU 26) and Baihui (DU 20) acupoints in the Du meridian group,as well as Chengjiang (RN 24),Guanyuan (RN 4),Renzhong,and Baihui acupoints in the Ren/Du meridian and Ren/Du meridian + PD98059 groups 2 days after model establishment. In addition,electro-acupuncture stimulation with disperse-dense waves was performed,with 30 Hz disperse wave,100 Hz dense wave,and 5 V intensity for 20 minutes. Rats in the Ren/Du meridian + PD98059 group were treated with 0.2 μg PD98059 injection into the subventricular zone,2 μL per rat. Rats in the model group were not treated with electro-acupuncture. MAIN OUTCOME MEASURES:BrdU/nestin immunofluorescent staining was used to detect proliferating neural stem cells in the subventricular zone of cerebral ischemia rats; Western blot was used to determine phosphorylated ERK1 and 2 (pERK1/2) expression in the subventricular zone. RESULTS:On days 14 and 28 after cerebral ischemia,there were significantly more BrdU-positive and BrdU/nestin-positive cells in the Ren /Du meridian group compared with the Du meridian group (P < 0.05). PD98059 decreased the number of BrdU-positive and BrdU/nestin-positive cells induced by electro-acupuncture at the Ren and Du meridians (P < 0.05). On days 7,14,and 28 after treatment,pERK1/2 expression was significantly greater in the Du meridian and Ren/Du meridian groups compared with the model group (P < 0.05). The promoting effect of electro-acupuncture at Ren and Du meridians on ERK1/2 phosphorylation was superior to electro-acupuncture at the Du meridian alone on day 14 after model induction (P < 0.05). However,PD98059 completely abolished the promoting effect of electro-acupuncture at Ren/Du meridians on pERK1/2 expression (P < 0.05). CONCLUSION:Electro-acupuncture at Ren and Du meridians increased proliferation of subventricular zone neural stem cells,which was related to activation of the ERK pathway in a rat model of cerebral ischemia injury.展开更多

文摘Objective:Red blood cell distribution width(RDW)has been utilized as a prognostic indicator for mortality risk assessment in cardiovascular and cerebrovascular patients.Nevertheless,the prognostic significance of RDW in critically ill patients with cerebral infarction is yet to be investigated.The objective of this study is to examine the association between RDW and the risk of all-cause mortality in cerebral infarction patients admitted to the intensive care unit(ICU).Method:A retrospective cohort study was conducted using the Medical Information Mart for Intensive Care IV 2.2(MIMIC-IV)intensive care dataset for data analysis.The main results were the all-cause mortality rates at 3 and 12 months of follow-up.Cumulative curves were plotted using the Kaplan-Meier method,and Cox proportional hazards analysis was used to examine the relationship between RDW and mortality rates in critically ill cerebral infarction patients.Results:The findings indicate that RDW serves as a significant prognostic factor for mortality risk in critically ill stroke patients,specifically at the 3 and 12-month follow-up periods.The observed correlation between increasing RDW levels and higher mortality rates among cerebral infarction patients further supports the potential utility of RDW as a predictive indicator.Conclusion:RDW emerges as an independent predictor of mortality risk during the 3 and 12-month follow-up periods for critically ill patients with cerebral infarction.
文摘Objective:To analyze the effect of limb rehabilitation therapy combined with transcranial magnetic stimulation therapy on muscle activity in patients with upper limb dysfunction after cerebral infarction(CI).Methods:320 patients with upper limb dysfunction after CI were selected,all of whom were treated in our hospital between June 2021 and June 2023.They were randomly grouped according to the lottery method into the control group(limb rehabilitation therapy,160 cases)and the intervention group(transcranial magnetic stimulation therapy+limb rehabilitation therapy,160 cases).The upper limb function scores,neuro-electrophysiological indicators,daily living ability scores,and quality of life scores of the two groups were compared.Results:Compared with the control group,upper limb function scores and daily living ability scores in the intervention group were higher after treatment,and the neuro-electrophysiological indicators of the intervention group were lower after treatment(P<0.05).Conclusion:Transcranial magnetic stimulation therapy combined with limb rehabilitation therapy has significant effects in patients with upper limb dysfunction after CI and is worthy of promotion and application.

文摘BACKGROUND Rehabilitation nursing is considered an indispensable part of the cerebral infarction treatment system.The hospital–community–family trinity rehabilitation nursing model can provide continuous nursing services across hospitals,communities,and families for patients.AIM To explore the application of a hospital–community–family rehabilitation nursing model combined with motor imagery therapy in patients with cerebral infarction.METHODS From January 2021 to December 2021,88 patients with cerebral infarction were divided into a study(n=44)and a control(n=44)group using a simple random number table.The control group received routine nursing and motor imagery therapy.The study group was given hospital–community–family trinity rehabilitation nursing based on the control group.Motor function(FMA),balance ability(BBS),activities of daily living(BI),quality of life(SS-QOL),activation status of the contralateral primary sensorimotor cortical area to the affected side,and nursing satisfaction were evaluated before and after intervention in both groups.RESULTS Before intervention,FMA and BBS were similar(P>0.05).After 6 months’intervention,FMA and BBS were significantly higher in the study than in the control group(both P<0.05).Before intervention,BI and SS-QOL scores were not different between the study and control group(P>0.05).However,after 6months’intervention,BI and SS-QOL were higher in the study than in the control group(P<0.05).Before intervention,activation frequency and volume were similar between the study and the control group(P>0.05).After 6 months’intervention,the activation frequency and volume were higher in the study than in the control group(P<0.05).The reliability,empathy,reactivity,assurance,and tangibles scores for quality of nursing service were higher in the study than in the control group(P<0.05).CONCLUSION Combining a hospital–community–family trinity rehabilitation nursing model and motor imagery therapy enhances the motor function and balance ability of patients with cerebral infarction,improving their quality of life.
文摘BACKGROUND The incidence rate of cerebral infarction in young people is increasing day by day,the age of onset tends to be younger,and its internal pathogenesis and mechanism are very complicated,which leads to greater difficulties in treatment.Therefore,it is essential to analyze the key pathway that affects the onset of cerebral infarction in young people from the perspective of genetics.AIM To compare the differentially expressed genes in the brain tissue of young and aged rats with middle cerebral artery occlusion and to analyse their effect on the key signalling pathway involved in the development of cerebral ischaemia in young rats.METHODS The Gene Expression Omnibus 2R online analysis tool was used to analyse the differentially expressed genes in the GSE166162 dataset regarding the development of cerebral ischaemia in young and aged groups of rats.DAVID 6.8 software was further used to filter the differentially expressed genes.These genes were subjected to Gene Ontology(GO)function analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis to determine the key gene pathway that affects the occurrence of cerebral ischaemia in young rats.RESULTS Thirty-five differentially expressed genes(such as Igf2,Col1a2,and Sfrp1)were obtained;73 GO enrichment analysis pathways are mainly involved in biological processes such as drug response,amino acid stimulation response,blood vessel development,various signalling pathways,and enzyme regulation.They are involved in molecular functions such as drug binding,protein binding,dopamine binding,metal ion binding,and dopamine neurotransmitter receptor activity.KEGG pathway enrichment analysis showed a significantly enriched pathway:The cyclic adenosine monophosphate(c-AMP)signalling pathway.CONCLUSION The c-AMP signalling pathway might be the key pathway in the intervention of cerebral infarction in young people.
文摘BACKGROUND Edaravone is a widely used treatment for patients with cerebral infarction and,in most cases,edaravone-induced side effects are mild.However,edaravone-related adverse reactions have been receiving increasing attention.CASE SUMMARY We treated three patients with acute cerebral infarction who died following treatment with edaravone.Edaravone is a widely used treatment for patients with cerebral infarction and,in most cases,edaravone-induced side effects are mild.However,edaravone-related adverse reactions have been receiving increasing attention.CONCLUSION Our cases highlight the importance of educating clinicians regarding the new edaravone-induced clinical syndromes of cerebral infarction as potentially fatal adverse drug reactions.Considering that no laboratory or confirmatory test exists to diagnose edaravone-induced death from cerebral infarction,clinicians’knowledge is the key element in recognizing this phenomenon.
文摘Background: Acute upper gastrointestinal bleeding in liver cirrhosis combined with acute cerebral infarction is uncommon in clinical work, and then combined with acute myelitis is even rarer and more complex, which poses a greater challenge to clinical diagnosis and treatment. This paper reports a case of acute upper gastrointestinal bleeding in liver cirrhosis complicated by acute cerebral infarction and acute myelitis, which be hoped to provide a reference for clinical work. Methods: We retrospectively evaluated the clinical information of a 68-year-old female admitted to the Digestive Medical Department with acute gastrointestinal bleeding and appeared limb movement disorder on the third day. Results: The patient was eventually diagnosed with acute upper gastrointestinal bleeding in liver cirrhosis complicated by acute cerebral infarction and acute myelitis. Conclusions: When patients with liver cirrhosis have abnormal neurological symptoms, in addition to liver cirrhosis-related complications, doctors need to consider cerebrovascular diseases and myelitis.
文摘BACKGROUND Acute cerebral infarction(ACI)is characterized by a high incidence of morbidity,disability,recurrence,death and heavy economic burden,and has become a disease of concern in global researchers.As ACI has serious effects on patients’physical status,life and economy,often causing anxiety,depression and other psychological problems,these problems can lead to the aggravation of physical symptoms;thus,it is very important to understand the factors affecting the mental health of these patients.AIM To understand the elements that affect the mental health of patients who have suffered an ACI.METHODS A questionnaire survey was conducted among patients with ACI admitted to three tertiary hospitals(Quanzhou First Hospital,Fuqing City Hospital Affiliated to Fujian Medical University,and the 900 Hospital of the Joint Service Support Force of the People’s Liberation Army of China)in Fujian Province from January 2022 to December 2022 using the convenience sampling method.ACI inpatients who met the inclusion criteria were selected.Informed consent was obtained from the patients before the investigation,and a face-to-face questionnaire survey was conducted using a unified scale.The questionnaire included a general situation questionnaire,Zung’s self-rating depression scale and Zung’s self-rating anxiety scale.All questionnaires were checked by two researchers and then the data were input and sorted using Excel software.The general situation of patients with ACI was analyzed by descriptive statistics,the influence of variables on mental health by the independent sample t test and variance analysis,and the influencing factors on psychological distress were analyzed by multiple stepwise regression.RESULTS The average age of the 220 patients with ACI was 68.64±10.74 years,including 142 males and 78 females.Most of the patients were between 60 and 74 years old,the majority had high school or technical secondary school education,most lived with their spouse,and most lived in cities.The majority of patients had a personal income of 3001 to 5000 RMB yuan per month.The new rural cooperative medical insurance system had the largest number of participants.Most stroke patients were cared for by their spouses and of these patients,52.3%had previously smoked.Univariate analysis showed that gender,age,residence,course of disease,number of previous chronic diseases and smoking history were the main factors affecting the anxiety scores of patients with ACI.Age,living conditions,monthly income,course of disease and knowledge of disease were the primary variables influencing the depression score in patients with ACI.The findings of multivariate analysis revealed that the course of disease and gender were the most important factors influencing patients’anxiety scores,and the course of disease was also the most important factor influencing patients’depression scores.CONCLUSION Long disease course and female patients with ACI were more likely to have psychological problems such as a high incidence of emotional disorders.These groups require more attention and counseling.

文摘Objective:To analyze the efficacy and safety of Ginkgo biloba tincture combined with conventional medication in the treatment of cerebral infarction by systematic evaluation.Methods:Searched the randomized controlled trials of Ginkgo biloba tincture in treating cerebral infarction.English literatures were searched from PubMed,EMbase,Cochrane Library and Web of Science,and Chinese literatures were searched from Chinese Biomedical Literature Database(CBM),China National Knowledge Infrastructure(CNKI),China Science and Technology Journal Database(VIP)and Wanfang Medical Database.At the same time,we searched dissertations,conference papers,and found relevant unpublished research results reports.Literature quality was evaluated using a"bias risk assessment tool"and Meta-analysis using RevMan 5.4 software(from the Cochrane Collaboration).A total of 29 literatures were retrieved,and finally 4 literatures meeting the standards were included.There were 455 samples involved,including 244 cases in the experimental group and 211 cases in the control group.Results:①Effectiveness analysis:The total effective rate of Ginkgo biloba tincture combined with routine treatment was better than that of the control group[RR=1.26,95%CI(1.07,1.47),P=0.005].The hematocrit of Ginkgo biloba tincture combined with conventional treatment was significantly better than that of conventional treatment alone(P<0.05),The neurological deficits of Ginkgo biloba tincture combined with routine therapy was significantly improved(P<0.05).After Ginkgo biloba tincture combined with conventional therapy,the scores of mini-mental state examination(MMSE),activity daily living scale(ADL)and MOSSF-36 quality of life scale were significantly better than those of the control group(P<0.05).②Safety analysis:3 articles reported the safety of medication.There was no obvious change in blood routine,liver and kidney function results and no adverse reactions in the experimental group and the control group.Conclusion:The above results indicated that Ginkgo biloba tincture combined with conventional treatment can improve the total effective rate of patients with cerebral infarction,and it is safe and has no adverse reactions.However,the number of literatures included in this study is small,and the quality of controlled trials is not good.It is still necessary to adopt clinical controlled trials with reasonable design,outcome indicators in line with international social norms and large sample content to further improve the evidence level of clinical research.
文摘Moyamoya disease(MMD),characterized by progressive internal carotid artery stenosis and collateral vessel formation,prompts cerebral perfusion complications and is stratified into idiopathic and Moyamoya syndrome subtypes.A multifa-ceted approach toward MMD management addresses cerebral infarctions through revascularization surgery and adjunctive medical therapy,while also navigating risks such as intracranial hemorrhage and cerebral infarction resulting from arte-rial stenosis and fragile collateral vessels.Addressing antithrombotic management reveals a potential role for treatments like antiplatelet agents and anticoagulants,despite the ambiguous contribution of thrombosis to MMD-related infarctions and the critical balance between preventing ischemic events and averting hemo-rrhagic complications.Transcranial doppler has proven useful in thromboembolic detection,despite persisting challenges concerning the efficacy and safety of an-tithrombotic treatments.Furthermore,antihypertensive interventions aim to ma-nage blood pressure meticulously,especially during intracerebral hemorrhage,with recommendations and protocols varying based on the patient’s hypertension status.Additionally,lipid-lowering therapeutic strategies,particularly employing statins,are appraised for their possible beneficial role in MMD management,even as comprehensive data from disease-specific clinical trials remains elusive.Com-prehensive guidelines and protocols to navigate the multifaceted therapeutic ave-nues for MMD,while maintaining a delicate balance between efficacy and safety,warrant further meticulous research and development.This protocol manuscript seeks to elucidate the various aspects and challenges imbued in managing and navigating through the complex landscape of MMD treatment.
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Low frequency(≤ 1 Hz) repetitive transcranial magnetic stimulation(r TMS) can affect the excitability of the cerebral cortex and synaptic plasticity. Although this is a common method for clinical treatment of cerebral infarction, whether it promotes the recovery of motor function remains controversial. Twenty patients with cerebral infarction combined with hemiparalysis were equally and randomly divided into a low frequency r TMS group and a control group. The patients in the low frequency r TMS group were given 1-Hz r TMS to the contralateral primary motor cortex with a stimulus intensity of 90% motor threshold, 30 minutes/day. The patients in the control group were given sham stimulation. After 14 days of treatment, clinical function scores(National Institute of Health Stroke Scale, Barthel Index, and Fugl-Meyer Assessment) improved significantly in the low frequency r TMS group, and the effects were better than that in the control group. We conclude that low frequency(1 Hz) r TMS for 14 days can help improve motor function after cerebral infarction.

文摘Studies have confirmed that low-frequency repetitive transcranial magnetic stimulation can decrease the activity of cortical neurons, and high-frequency repetitive transcranial magnetic stimulation can increase the excitability of cortical neurons. However, there are few studies concerning the use of different frequencies of repetitive transcranial magnetic stimulation on the recovery of upper-limb motor function after cerebral infarction. We hypothesized that different frequencies of repetitive transcranial magnetic stimulation in patients with cerebral infarction would produce different effects on the recovery of upper-limb motor function. This study enrolled 127 patients with upper-limb dysfunction during the subacute phase of cerebral infarction. These patients were randomly assigned to three groups. The low-frequency group comprised 42 patients who were treated with 1 Hz repetitive transcranial magnetic stimulation on the contralateral hemisphere primary motor cortex(M1). The high-frequency group comprised 43 patients who were treated with 10 Hz repetitive transcranial magnetic stimulation on ipsilateral M1. Finally, the sham group comprised 42 patients who were treated with 10 Hz of false stimulation on ipsilateral M1. A total of 135 seconds of stimulation was applied in the sham group and high-frequency group. At 2 weeks after treatment, cortical latency of motor-evoked potentials and central motor conduction time were significantly lower compared with before treatment. Moreover, motor function scores were significantly improved. The above indices for the low- and high-frequency groups were significantly different compared with the sham group. However, there was no significant difference between the low- and high-frequency groups. The results show that low- and high-frequency repetitive transcranial magnetic stimulation can similarly improve upper-limb motor function in patients with cerebral infarction.

文摘Many studies using diffusion tensor tractography(DTT) have demonstrated that injury of the spinothalamic tract(STT) is the pathogenetic mechanism of central post-stroke pain(CPSP) in intracerebral hemorrhage; however, there is no DTT study reporting the pathogenetic mechanism of CPSP in cerebral infarction. In this study, we investigated injury of the STT in patients with CPSP following cerebral infarction, using DTT. Five patients with CPSP following cerebral infarction and eight age-and sex-matched healthy control subjects were recruited for this study. STT was examined using DTT. Among DTT parameters of the affected STT, fractional anisotropy and tract volume were decreased by more than two standard deviations in two patients(patients 1 and 2) and three patients(patients 3, 4, and 5), respectively, compared with those of the control subjects, while mean diffusivity value was increased by more than two standard deviations in one patient(patient 2). Regarding DTT configuration, all affected STTs passed through adjacent part of the infarct and three STTs showed narrowing. These findings suggest that injury of the STT might be a pathogenetic etiology of CPSP in patients with cerebral infarction.

文摘BACKGROUND:Studies have shown that electro-acupuncture at the Ren meridian could improve proliferation of subventricular zone neural stem cells in cerebral-ischemic rats. However,there are few reports on the influence of electro-acupuncture at the Du meridian on neural stem cell proliferation. OBJECTIVE:To observe the influence of electro-acupuncture at Ren and Du meridians on neural stem cell proliferation in the subventricular zone and altered signal transduction in cerebral ischemia rats. DESIGN,TIME AND SETTING:A randomized,controlled,animal experiment was performed at the Laboratory of Human Anatomy,Medical College of Sun Yat-sen University from May 2006 to February 2008. MATERIALS:Mouse anti-rat bromodeoxyuridine (BrdU) monoclonal antibody was provided by Sigma,USA; mouse anti-rat nestin monoclonal antibody and extracellular signal-regulated protein kinase (ERK) specific inhibitor PD98059 were provided by Calbiochem,Germany; acupuncture needle was provided by Suzhou Acupuncture Supplies,China. METHODS:A total of 126 rats were randomly assigned to four groups:model (n = 36),Du meridian (n = 36),Ren/Du meridian (n = 36),and Ren/Du meridian + PD98059 (n = 18). Rats in the Ren /Du meridian + PD98059 group were observed on days 7 (n = 6) and 14 (n = 12) after cerebral ischemia injury. Rats in the model,Du meridian,and Ren/Du meridian groups were observed on days 7,14,and 28 after cerebral ischemia injury,with 12 rats per group at each time point. Thread occlusion was used to establish middle cerebral artery occlusion models. Electro-acupuncture was performed at Renzhong (DU 26) and Baihui (DU 20) acupoints in the Du meridian group,as well as Chengjiang (RN 24),Guanyuan (RN 4),Renzhong,and Baihui acupoints in the Ren/Du meridian and Ren/Du meridian + PD98059 groups 2 days after model establishment. In addition,electro-acupuncture stimulation with disperse-dense waves was performed,with 30 Hz disperse wave,100 Hz dense wave,and 5 V intensity for 20 minutes. Rats in the Ren/Du meridian + PD98059 group were treated with 0.2 μg PD98059 injection into the subventricular zone,2 μL per rat. Rats in the model group were not treated with electro-acupuncture. MAIN OUTCOME MEASURES:BrdU/nestin immunofluorescent staining was used to detect proliferating neural stem cells in the subventricular zone of cerebral ischemia rats; Western blot was used to determine phosphorylated ERK1 and 2 (pERK1/2) expression in the subventricular zone. RESULTS:On days 14 and 28 after cerebral ischemia,there were significantly more BrdU-positive and BrdU/nestin-positive cells in the Ren /Du meridian group compared with the Du meridian group (P < 0.05). PD98059 decreased the number of BrdU-positive and BrdU/nestin-positive cells induced by electro-acupuncture at the Ren and Du meridians (P < 0.05). On days 7,14,and 28 after treatment,pERK1/2 expression was significantly greater in the Du meridian and Ren/Du meridian groups compared with the model group (P < 0.05). The promoting effect of electro-acupuncture at Ren and Du meridians on ERK1/2 phosphorylation was superior to electro-acupuncture at the Du meridian alone on day 14 after model induction (P < 0.05). However,PD98059 completely abolished the promoting effect of electro-acupuncture at Ren/Du meridians on pERK1/2 expression (P < 0.05). CONCLUSION:Electro-acupuncture at Ren and Du meridians increased proliferation of subventricular zone neural stem cells,which was related to activation of the ERK pathway in a rat model of cerebral ischemia injury.

文摘13-Methyltetradecanoic acid can stabilize cell membrane and have anti-inflammatory,antioxidant and anti-apoptotic effects.Previous studies mainly focused on peripheral nerve injury,but seldom on the central nervous system.We investigated whether these properties of 13-methyltetradecanoic acid have a neuroprotective effect on focal cerebral ischemia/reperfusion injury,and detected the expression of basic fibroblast growth factor and vascular endothelial growth factor.This study established rat models of middle cerebral artery occlusion/reperfusion injury by ischemia for 2 hours and reperfusion for 24 hours.At the beginning of reperfusion,13-methyltetradecanoic acid 10,40 or 80 mg/kg was injected into the tail vein.Results found that various doses of 13-methyltetradecanoic acid effectively reduced infarct volume,mitigate cerebral edema,and increased the m RNA and protein expression of basic fibroblast growth factor and vascular endothelial growth factor at 24 hours of reperfusion.The effect was most significant in the 13-methyltetradecanoic acid 40 and 80 mg/kg groups.The findings suggest that 13-methyltetradecanoic acid can relieve focal ischemia/reperfusion injury immediately after reperfusion,stimulate the upregulation of basic fibroblast growth factor and vascular endothelial growth factor to exert neuroprotective effects.
文摘BACKGROUND In both national and international studies,the safety and effectiveness of treatment with the Solitaire stent in patients with ischemic stroke caused by acute large vessel occlusion were good,and the disability rate was significantly reduced.However,there are currently only a few reports on the differences in endovascular treatment for different etiological classifications,especially in the anterior cranial circulation,aorta atherosclerotic stenosis,and acute thrombosis.AIM To investigate the efficacy of Solitaire AB stent-release angioplasty in patients with acute middle cerebral artery atherosclerosis obliterative cerebral infarction.METHODS Twenty-five patients with acute middle cerebral atherosclerosis obliterative cerebral infarction were retrospectively enrolled in this study from January 2017 to December 2019.The Solitaire AB stent was used to improve anterior blood flow to maintain modified cerebral infarction thrombolysis[modified thrombolysis in cerebral infarction(mTICI)]at the 2b/3 level or above,the stent was then unfolded and released.RESULTS All 25 patients underwent successful surgery,with an average recanalization time of 23 min.One patient died of cerebral hemorrhage and cerebral herniation after the operation.The National Institutes of Health Stroke Scale(NIHSS)scores immediately after surgery(7.5±5.6),at 24 h(5.5±5.6)and at 1 wk(3.6±6.7)compared with the preoperative NIHSS score(15.9±4.4),were significantly different(P<0.01).One case of restenosis was observed 3 mo after surgery(the stenosis rate was 50%without clinical symptoms),the modified Rankin scale scores were 0 points in 14 cases(56%),1 point in 4 cases(16%),2 points in 2 cases(8%),3 points in 3 cases(12%),4 points in 1 case(4%),and 6 points in 1 case(4%).CONCLUSION In acute middle cerebral artery atherosclerosis obliterative cerebral infarction,when the Solitaire AB stent is unfolded and the forward blood flow is maintained at mTICI level 2b/3 or higher,stent release may be a safe and effective treatment method;however,long-term observation and a larger sample size are required to verify these findings.
文摘BACKGROUND Acute cerebral infarction is a severe type of ischemic stroke that can be divided into anterior circulation cerebral infarction and posterior circulation cerebral infarction(PCCI).PCCI affects the structure of the posterior circulation brain,because posterior part of the brain,which has more complex anatomical structures and more prone to posterior circulation vascular variation.Therefore,improving the prognosis of PCCI patients is necessary.AIM To explore the effect of medical care linkage-continuous management mode(MCLMM)on endovascular interventional therapy(EIT)for PCCI.METHODS Sixty-nine patients with PCCI who received EIT and conventional nursing intervention were selected as the control group,and 78 patients with PCCI who received EIT and MCLMM intervention were selected as the observation group.The incidence of postoperative complications,compliance and disease selfmanagement behavior after six months of intervention,modified Rankin scale(mRS)and Barthel index(BI)scores in the acute phase and after one year of intervention,and recurrence within one year were compared between the two groups.RESULTS The total incidence rate of postoperative complications in the observation group(7.69%)was lower than that in the control group(18.84%)(P<0.05).The scores for medical compliance behavior(regular medication,appropriate diet,and rehabilitation cooperation rates)and disease self-management behavior(self-will,disease knowledge,and self-care ability)in the observation group were higher than those in the control group(P<0.05).After one year of intervention,in the observation group,the mRS score was significantly lower,and the BI score was significantly higher than those in the control group(P<0.05).The recurrence rate within one year in the observation group(3.85%)was significantly lower than that in the control group(13.04%)(P<0.05).CONCLUSION MCLMM can reduce the incidence of complications after EIT for PCCI,improve patient compliance behavior and disease self-management ability,and promote the recovery of neurological function.
文摘Severe cerebral ischemia/reperfusion injury has been shown to induce high-level autophagy and neuronal death.Therefore,it is extremely important to search for a target that inhibits autophagy activation.Long non-coding RNA MEG3 participates in autophagy.However,it remains unclear whether it can be targeted to regulate cerebral ischemia/reperfusion injury.Our results revealed that in oxygen and glucose deprivation/reoxygenation-treated HT22 cells,MEG3 expression was obviously upregulated,and autophagy was increased,while knockdown of MEG3 expression greatly reduced autophagy.Furthermore,MEG3 bound mi R-181 c-5 p and inhibited its expression,while mi R-181 c-5 p bound to autophagy-related gene ATG7 and inhibited its expression.Further experiments revealed that mir-181 c-5 p overexpression reversed the effect of MEG3 on autophagy and ATG7 expression in HT22 cells subjected to oxygen and glucose deprivation/reoxygenation.In vivo experiments revealed that MEG3 knockdown suppressed autophagy,infarct volume and behavioral deficits in cerebral ischemia/reperfusion mice.These findings suggest that MEG3 knockdown inhibited autophagy and alleviated cerebral ischemia/reperfusion injury through the mi R-181 c-5 p/ATG7 signaling pathway.Therefore,MEG3 can be considered as an intervention target for the treatment of cerebral ischemia/reperfusion injury.This study was approved by the Animal Ethics Committee of the First Affiliated Hospital of Zhengzhou University,China(approval No.XF20190538)on January 4,2019.
文摘BACKGROUND Cerebral infarction patients need to be bedridden for long periods of time often resulting in pressure injuries,which may represent a serious threat to patients'life and health.An effective nursing program should be adopted for timely intervention in patients with pressure wounds.AIM To explore the value of nursing services based on a multidisciplinary collaborative treatment team in patients with pressure injury wounds following cerebral infarction.METHODS Patients with cerebral infarction pressure injury wounds in our hospital from December 2016 to January 2021 were selected and divided into one study group and one control group based on the simple random number table method.The control group was treated with conventional nursing care(CNC),and the study group was treated with care services based on multidisciplinary collaborative care(MDCC).The Pressure Ulcer Scale for Healing(PUSH),healing effect,Self-Perceived Burden Score(SPBS),and satisfaction with the intervention were calculated before and after 2 and 4 wk of intervention in both groups.RESULTS Sixty-two patients were enrolled,and 31 patients were assigned to each group.The results of the interventions were as follows:(1)There was no significant difference between the PUSH scores of the MDCC group(11.19±2.46)and CNC group(12.01±2.79)before the intervention(P>0.05),and the PUSH scores were lower after 2 and 4 wk of intervention in the MDCC group(6.63±1.97 and 3.11±1.04)than in the CNC group(8.78±2.13 and 4.96±1.35 points)(P<0.05);(2)The rate of wound healing in the MDCC group(96.77%)was higher than that in the CNC group(80.65%)(P<0.05);(3)There was no significant difference between the SPBS scores of emotional factors(21.15±3.11),economic factors(9.88±2.15),and physical factors(8.19±2.23)in the two groups before the intervention.The scores of emotional factors(13.51±1.88),economic factors(6.38±1.44),and physical factors(5.37±1.08)were lower in the MDCC group than in the CNC group(16.89±2.05,7.99±1.68 and 7.06±1.19)after 4 wk of intervention(P<0.05);and(4)Satisfaction with the intervention was higher in the MDCC group(93.55%)than in the CNC group(74.19%)(P<0.05).CONCLUSION Interventions for patients with cerebral infarction pressure wounds based on an MDCC treatment team can effectively reduce patients'self-perceived burden,improve pressure wound conditions,facilitate wound healing,and increase patient satisfaction with the intervention.
