Susceptibility gene for stroke or cerebral infarction in the Han population in Hunan Province of China

The scavenger receptor class B type I gene can protect against atherosclerosis; a mononucleotide polymorphism is associated with differences in blood lipid metabolism, postprandial serum lipid levels, insulin resistance, coronary artery disease and familial hyperlipidemia. In this study, the scavenger receptor class B type I gene exon 1 G4A gene polymorphism in atherosclerotic cerebral infarction patients, cerebral hemorrhage patients and normal controls was detected using the polymerase chain reaction-restriction fragment length polymorphism method. The results showed that the GA ＋ AA genotype frequency of scavenger receptor class B type I gene G4A in atherosclerotic cerebral infarction patients was similar to that in cerebral hemorrhage patients and normal controls; however, the A allele frequency was significantly lower than that in normal controls. The serum level of high-density lipoprotein cholesterol in patients with the scavenger receptor class B type I gene G4A GA ＋ AA genotype was significantly higher, while the serum level of low-density lipoprotein cholesterol was significantly lower than that in patients with the GG genotype, in both the atherosclerotic cerebral infarction and cerebral hemorrhage groups. The serum level of high-density lipoprotein cholesterol in patients with the scavenger receptor class B type I gene G4A GA ＋ AA genotype was significantly higher, while the serum levels of low-density lipoprotein cholesterol and total cholesterol were significantly lower than those in normal controls with the GG genotype. Our experimental results suggest that the G4A polymorphism of the scavenger receptor class B type I gene is a possible predisposing risk factor for atherosclerotic cerebral infarction, and that it has no association with cerebral hemorrhage in the Hart population in Hunan province of China. The A allele is possibly associated with the metabolism of high-density and low-density lipoprotein cholesterol.

Central post-stroke pain due to injury of the spinothalamic tract in patients with cerebral infarction： a diffusion tensor tractography imaging study

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.

High matrix metalloproteinase-9 expression induces angiogenesis and basement membrane degradation in stroke-prone spontaneously hypertensive rats after cerebral infarction

Basement membrane degradation and blood-brain barrier damage appear after cerebral infarc- tion, severely impacting neuronal and brain functioning; however, the underlying pathogenetic mechanisms remain poorly understood. In this study, we induced cerebral infarction in stroke- prone spontaneously hypertensive rats by intragastric administration of high-sodium water （1.3% NaC1） for 7 consecutive weeks. Immunohistochemical and immunofluorescence assays demonstrated that, compared with the non-infarcted contralateral hemisphere, stroke-prone spontaneously hypertensive rats on normal sodium intake and Wistar-Kyoto rats, matrix metalloproteinase-9 expression, the number of blood vessels with discontinuous collagen IV expression and microvessel density were significantly higher, and the number of continuous collagen IV-positive blood vessels was lower in the infarct border zones of stroke-prone sponta- neously hypertensive rats given high-sodium water. Linear correlation analysis showed matrix metalloproteinase-9 expression was positively correlated with the number of discontinuously collagen IV-labeled blood vessels and microvessel density in cerebral infarcts of stroke-prone spontaneously hypertensive rats. These results suggest that matrix metalloproteinase-9 upregula- tion is associated with increased regional angiogenesis and degradation of collagen IV, the major component of the basal lamina, in stroke-prone spontaneously hypertensive rats with high-sodi- um water-induced focal cerebral infarction.

Risk Factors for Prevention Stroke (IS or TIA) Due to Cerebral Infarction in Young Adults: A Meta-Analytical Study

Ischemic strokes (IS), also referred to as cerebral ischemia or brain ischemia, is a significant cause to the brain cells damage or death. Approximately, 10% - 14% of ischemic strokes cases occurred in young adults. Hence, we conducted a meta-analysis to find the effective interventions to prevent the best strokes caused by cerebral infarction in young adults. The search was done in different databases, including Google scholar, PubMed, Embase, Medline, Cochrane Central Register of Controlled Trials, Cochrane Database, Scopus, and Web of Science from January 2016 to April 2020, and only English published articles were considered. Our analysis included studies that stratified the risk of ischemic stroke by CHA2DS2-VASc score for patients with nonvalvular atrial fibrillation. Further, random effects model was used to estimate the summary annual rate of IS. Pooled relative risks and odds ratios, with their 95% confidence intervals, were calculated, respectively. The analysis was conducted using STATA (version 12), pooled effect sizes were calculated using the random-effects model and heterogeneity was tested for using the I2 statistic. The analysis included 13 studies. The analysis shows that diabetes, high blood pressure, ischemic heart disease, atrial fibrillation, hypercholesterolemia, alcohol consumption and smoking are significant risk factors. In Caucasian and Chinese ischemic stroke patients, the risk factor associations associated with ischemic stroke subtypes are similar. Compared to all other ischemia subtypes, diabetes is more familiar with aortic stroke, atrial fibrillation, ischemic heart disease (with obstruction), hypertension and diabetes. Our research shows that atrial fibrillation, ischemic heart disease, and hypercholesterolemia are low in patients with ischemic stroke and the risk factors are higher. Further analysis of each patient’s data is required to enable confounders’ adjustments to confirm and expand these findings.

Effect of adjuvant Naoxintong capsule therapy on nerve function and inflammatory stress response in patients in convalescence of cerebral infarction

Objective: To explore the effect of adjuvant Naoxintong capsule therapy on nerve function and inflammatory stress response in patients in convalescence of cerebral infarction. Methods:91 patients with cerebral infarction who were treated in our hospital between September 2015 and October 2017 were selected as the research subjects, and the medication during convalescence was reviewed and used to divide all patients into the control group (n=50) who received conventional western medicine treatment and the Naoxintong capsule group (n=41) who received western medicine combined with Naoxintong capsule treatment. The differences in serum levels of nerve function indexes, inflammatory mediators and oxidative stress indexes were compared between the two groups before convalescence medication (T1) and after 1 month of convalescence treatment (T2). Results: At T1, serum levels of nerve function indexes, inflammatory mediators and oxidative stress indexes were not significantly different between the two groups. At T2, serum nerve function indexes Copeptin and α-HBDH levels of Naoxintong capsule group were lower than those of control group whereas BDNF and IGF-1 levels were higher than those of control group;serum inflammatory mediators hs-CRP, YKL-40, IL-6 and IL-18 levels were lower than those of control group;serum oxidative stress index SOD level was higher than that of control group whereas 8-OHdG and MDA levels were lower than those of control group. Conclusion: Adjuvant Naoxintong capsule therapy can be further optimize the nerve function and relieve the inflammatory stress response in patients in convalescence of cerebral infarction.

Effect of acupuncture combined with drug therapy on the nerve cytokine secretion and oxidative stress in convalescence of cerebral infarction

Objective: To explore the effect of acupuncture combined with drug therapy on the nerve cytokine secretion and oxidative stress in convalescence of cerebral infarction. Methods: A total of 118 patients in convalescence of cerebral infarction who were treated in the affiliated hospital of our school between August 2014 and December 2016 were divided into control group (n=59) and observation group (n=59) according to the random number table method. Control group received routine drug therapy, and the observation group received acupuncture combined with drug therapy. The differences in serum levels of neurotrophic factors, nerve injury factors and oxidative stress indexes were compared between the two groups before and after treatment. Results: The differences in serum levels of neurotrophic factors, nerve injury factors and oxidative stress indexes were not statistically significant between the two groups before treatment. After treatment, serum neurotrophic factors IGF-1, BDNF and NGF levels of observation group were higher than those of control group;nerve injury factors S-100β, NSE, GFAP and UCH-L1 levels were lower than those of control group;oxidative stress indexes MDA, AOPPs and LHP levels were lower than those of control group while SOD and GSH-Px levels were higher than those of control group. Conclusion: Acupuncture combined with drug therapy can effectively optimize the nerve function, reduce the nerve injury and suppress the systemic oxidative stress response of patients in convalescence of cerebral infarction.

Efficacy of cattle encephalon glycoside and ignotin in patients with acute cerebral infarction: a randomized, double-blind, parallel-group, placebo-controlled study

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).

Low frequency repetitive transcranial magnetic stimulation improves motor dysfunction after cerebral infarction

Low frequency （≤ 1 Hz） repetitive transcranial magnetic stimulation （rTMS） 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 rTMS group and a control group. The patients in the low frequency rTMS group were given 1-Hz rTMS 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 rTMS group, and the effects were better than that in the control group. We conclude that low frequency （1 Hz） rTMS for 14 days can help improve motor function after cerebral infarction.

Effects of different frequencies of repetitive transcranial magnetic stimulation on the recovery of upper limb motor dysfunction in patients with subacute cerebral infarction

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.

Use of acupuncture to treat cerebral infarction in the last 10 years A Scopus-based literature analysis

OBJECTIVE： To identify global research trends in the use of acupuncture to treat cerebral infarction. DATA RETRIEVAL： We performed a bibliometric analysis of studies on the use of acupuncture to treat cerebral infarction published during 2002-2011, retrieved from Scopus, using the key words of acupuncture and cerebral infarction or ischemic stroke. SELECTION CRITERIA： Inclusion criteria： peer-reviewed articles on the use of acupuncture to treat cerebral infarction indexed in Scopus and published between 2002 and 2011; types of publications were original research articles, reviews, meeting abstracts, proceedings papers, book chapters, editorial material, and news items. Exclusion criteria： articles that required manual searching or telephone access; documents that were not published in the public domain; and corrected papers. MAIN OUTCOME MEASURES： （a） Annual publication output; （b） language of publication; （c） type of publication; （d） key words of publication; （e） publication by research field; （f） publication by journal （g） publication by country and institution; （h） publication by author; （i） most-cited papers between 2002 and 2006; and （j） most-cited papers between 2007 and 2011. RESULTS： A total of 160 publications on the use of acupuncture to treat cerebral infarction from 2002-2011 were retrieved from Scopus. The number of publications increased gradually over the 10-year study period; most were written in Chinese or English. Articles and reviews constituted the major types. The most frequent key word used was acupuncture. The most prolific journals in this area were Zhongguo 7hen Jiu and the Chinese Journal of Clinical Rehabilitation. Of the 160 publications retrieved, half came from Chinese authors and institutions. Tianjin University of Traditional Chinese Medicine was the most prolific research institute. Two papers were cited 30 times; they were published in 2002 and 2009, respectively. CONCLUSION： In the field of neuroscience, there is little literature on acupuncture for cerebral infarction. The most-cited papers were cited 30 times in the past 3 years. We believe that, with advances in the study of mechanisms in neurobiology, research on acupuncture will also advance and will become the concern of more scholars.

Major ozonated autohemotherapy promotes the recovery of upper limb motor function in patients with acute cerebral infarction

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.

Predictive power of abnormal electroencephalogram for post-cerebral infarction depression

Electroencephalography is a sensitive indicator for measuring brain condition, and can reflect early changes in brain function and severity of cerebral ischemia. However, it is not yet known whether electroencephalography can predict development of post-cerebral infarc- tion depression. A total of 321 patients with ischemic stroke underwent electroencephalography and Hamilton Depression Rating Scale assessment to analyze the relationship between electroencephalography and post-cerebral infarction depression. Our results show that electroencephalograms of ischemic stroke patients with depression exhibit low-amplitude alpha activity and slow theta activity. In con- trast, electroencephalograms of ischemic stroke patients without depression show fast beta activity and slow delta activity. ＂Ihese findings confirm that low-amplitude alpha activity and slow theta activity can be considered as independent predictors for post-cerebral infarction depression.

Nursing perspective of expert consensus on the diagnosis and treatment of cerebral infarction with integrated traditional Chinese and Western medicine

Cerebral infarction(CI)is also known as ischemic stroke.It is one of the most common cerebrovascular diseases,with high mortality and disability rate,which has seriously threatened human health.To better apply the diagnosis and treatment plan of integrated traditional Chinese and Western medicine to the treatment of patients with CI,the Chinese Association of Integrative Medicine issued the Expert Consensus on the Diagnosis and Treatment of Cerebral Infarction with the Integrated Traditional Chinese and Western Medicine in 2021.It involves etiology and pathogenesis of CI,diagnosis and treatment standards of Traditional Chinese Medicine(TCM)and Western Medicine,syndrome elements of TCM,as well as rehabilitation nursing of CI with integrated traditional Chinese and Western medicine during acute period and recovery period.This study interprets the consensus from routine nursing,dietary nursing,emotional nursing,complication nursing,rehabilitation nursing,and continuous nursing,aiming to provide evidence-based support for clinical TCM nursing practice.

β2-Microglobulin exacerbates neuroinflammation,brain damage,and cognitive impairment after stroke in rats

β2-Microglobulin(β2M),a component of the major histocompatibility complex class I molecule,is associated with aging-related cognitive impairment and Alzheimer’s disease.Although upregulation ofβ2M is considered to be highly related to ischemic stroke,the specific role and underlying mechanistic action ofβ2M are poorly understood.In this study,we established a rat model of focal cerebral ischemia by occlusion of the middle cerebral artery.We found thatβ2M levels in the cerebral spinal fluid,serum,and brain tissue were significantly increased in the acute period but gradually decreased during the recovery period.RNA interference was used to inhibitβ2M expression in the acute period of cerebral stroke.Tissue staining with 2,3,5-triphenyltetrazolium chloride and evaluation of cognitive function using the Morris water maze test demonstrated that decreasedβ2M expression in the ischemic penumbra reduced infarct volume and alleviated cognitive deficits,respectively.Notably,glial cell,caspase-1(p20),and Nod-like receptor pyrin domain containing 3(NLRP3)inflammasome activation as well as production of the inflammatory cytokines interleukin-1β,interleukin-6,and tumor necrosis factor-αwere also effectively inhibited byβ2M silencing.These findings suggest thatβ2M participates in brain injury and cognitive impairment in a rat model of ischemic stroke through activation of neuroinflammation associated with the NLRP3 inflammasome.

Relationship between Onset of Cerebral Infarction and Classification of Meteorological Elements

It is well recognized that there are many kinds of diseases that are affected by meteorological factors. This study aims at investing the relation between the onset of cerebral infarction (CI) and climatic elements. Databases of medical emergency transfers in Nagoya during the winter seasons of 2002-2004 were reviewed. We applied a bi-directional self-organizing map (SOM), cluster analysis and decision tree to estimate the effects of climatic elements on the onset of CI. We classified climatic elements into three patterns, such as “rainy weather”, “west high and east low pressure” and “fair weather” by applying SOM. The risk of CI was estimated more clearly over each pattern. The meteorological variances are associated with the onset of CI. This fact was more accurately observed by classification of climatic patterns based on SOM. This study also suggests that effective warning is possible for the onset of CI, if we classify weather patterns.

Influence of Xiaoshuan enteric-coated capsules + aniracetam therapy on cerebral blood perfusion and nerve function in patients with convalescent cerebral infarction

Objective: To investigate the influence of Xiaoshuan enteric-coated capsules + aniracetam therapy on cerebral blood perfusion and nerve function in patients with convalescent cerebral infarction. Methods: A total of 177 cases of patients with convalescent cerebral infarction were retrospectively reviewed and then divided into the control group (n=109) and the Xiaoshuan enteric-coated capsules group (n=68). Control group received aniracetam therapy on the basis of routine treatment, and Xiaoshuan enteric-coated capsules group received Xiaoshuan enteric-coated capsules + aniracetam therapy on the basis of routine treatment. The differences in ultrasound cerebral blood perfusion parameter levels as well as serum neurotrophy index and nerve injury index contents were compared between the two groups. Results: Before treatment, there was no statistically significant difference in ultrasound cerebral blood perfusion parameter levels as well as serum neurotrophy index and nerve injury index contents between the two groups. After treatment, ultrasound cerebral blood perfusion parameters PSV and TMV levels in Xiaoshuan enteric-coated capsules group were higher than those in control group whereas RI level was lower than that in control group;serum neurotrophy indexes bFGF, BDNF and VEGF contents were higher than those of control group;serum nerve injury indexes GFAP, NSE, UCH-L1 and S100B contents were lower than those of control group. Conclusion: Xiaoshuan enteric-coated capsules + aniracetam therapy can significantly increase cerebral blood perfusion and optimize nerve function in patients with convalescent cerebral infarction.
