Analysis of the Effect of Limb Rehabilitation Therapy Combined with Transcranial Magnetic Stimulation Therapy on Muscle Activity in Patients with Upper Limb Dysfunction After Cerebral Infarction

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.

The Effect of Predictive Nursing Intervention on Cardiac Function and Clinical Outcomes in CCU Patients with Acute Myocardial Infarction After Interventional Therapy

Objective:To evaluate the impact of predictive nursing on the care of acute myocardial infarction(AMI)patients in the Coronary Care Unit(CCU)after interventional therapy.Methods:From September 2021 to September 2023,84 AMI patients admitted to the CCU were randomly divided into two groups:the experimental group(42 patients)received predictive nursing,and the reference group(42 patients)received conventional nursing.Cardiac function and clinical outcomes were compared between the groups.Results:Before nursing,there was no difference in cardiac function between the two groups(P>0.05).After nursing,the cardiac function of the experimental group was better than that of the reference group(P<0.05).The clinical outcomes of the experimental group were better than those of the reference group(P<0.05).Before nursing,there was no difference in psychological scores between the two groups(P>0.05).After nursing,the psychological scores of the experimental group were lower than those of the reference group(P<0.05).Conclusion:Predictive nursing can improve the cardiac function and clinical outcomes of AMI patients after interventional therapy and can also regulate patients’negative psychological states.

Application of a hospital–community–family trinity rehabilitation nursing model combined with motor imagery therapy in patients with cerebral infarction

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.

Assessment of post-myocardial infarction lipid levels and management:Results from a tertiary care hospital of Pakistan

BACKGROUND Lipid treatment practices and levels in post-acute myocardial infarction(AMI)patients,which are crucial for secondary prevention.AIM To evaluate the lipid treatment practices and lipid levels in post-myocardial infarction(MI)patients at a tertiary care hospital in Pakistan.METHODS In this cross-sectional study,we analyzed patients who had experienced their first AMI event in the past 3 years.We assessed fasting and non-fasting lipid profiles,reviewed statin therapy prescriptions,and examined patient compliance.The recommended dose was defined as rosuvastatin≥20 mg or atorvastatin≥40 mg,with target total cholesterol levels set at<160 mg/dL and target low-density lipoprotein cholesterol(LDL-C)at<55 mg/dL.RESULTS Among 195 patients,71.3%were male,and the mean age was 57.1±10.2 years.The median duration since AMI was 36(interquartile range:10-48)months and 60% were diagnosed with ST-segment elevation MI.Only 13.8% of patients were advised to undergo lipid profile testing after AMI,88.7% of patients were on the recommended statin therapy,and 91.8% of patients were compliant with statin therapy.Only 11.5% had LDL-C within the target range and 71.7% had total cholesterol within the target range.Hospital admission in the past 12 months was reported by 14.4%,and the readmission rate was significantly higher among non-compliant patients(37.5%vs 5.6%).Subsequent AMI event rate was also significantly higher among non-compliant patients(43.8%vs 11.7%).CONCLUSION Our study highlights that while most post-AMI patients received the recommended minimum statin therapy dose,the inadequate practice of lipid assessment may compromise therapy optimization and raise the risk of subsequent events.

Chemotherapy combined with bevacizumab for small cell lung cancer with brain metastases:A case report

BACKGROUND Small cell lung cancer(SCLC)is a common and aggressive subtype of lung cancer.It is characterized by rapid growth and a high mortality rate.Approximately 10%of patients with SCLC present with brain metastases at the time of diagnosis,which is associated with a median survival of 5 mo.This study aimed to summarize the effect of bevacizumab on the progression-free survival(PFS)and overall survival of patients with brain metastasis of SCLC.CASE SUMMARY A 62-year-old man was referred to our hospital in February 2023 because of dizziness and numbness of the right lower extremity without headache or fever for more than four weeks.The patient was diagnosed with limited-stage SCLC.He received 8 cycles of chemotherapy combined with maintenance bevacizumab therapy and achieved a PFS of over 7 mo.CONCLUSION The combination of bevacizumab and irinotecan effectively alleviated brain metastasis in SCLC and prolonged PFS.

Inetetamab combined with pyrotinib and chemotherapy in the treatment of breast cancer brain metastasis: A case report

BACKGROUND Breast cancer brain metastasis(BCBM)is an advanced breast disease that is difficult to treat and is associated with a high risk of death.Patient prognosis is usually poor,with reduced quality of life.In this context,we report the case of a patient with HER-2-positive BCBM treated with a macromolecular mAb(ine-tetamab)combined with a small molecule tyrosine kinase inhibitor(TKI).CASE SUMMARY The patient was a 58-year-old woman with a 12-year history of type 2 diabetes.She was compliant with regular insulin treatment and had good blood glucose control.The patient was diagnosed with invasive carcinoma of the right breast(T3N1M0 stage IIIa,HER2-positive type)through aspiration biopsy of the ipsilateral breast due to the discovery of a breast tumor in February 2019.Immunohistochemistry showed ER(-),PR(-),HER-2(3+),and Ki-67(55-60%+).Preoperative neoadjuvant chemotherapy,i.e.,the AC-TH regimen(epirubicin,cyclophosphamide,docetaxel-paclitaxel,and trastuzumab),was administered for 8 cycles.She underwent modified radical mastectomy of the right breast in November 2019 and received tocilizumab targeted therapy for 1 year.Brain metastasis was found 9 mo after surgery.She underwent brain metastasectomy in August 2020.Immunohistochemistry showed ER(-)and PR.(-),HER-2(3+),and Ki-67(10-20%+).In November 2020,the patient experienced headache symptoms.After an examination,tumor recurrence in the original surgical region of the brain was observed,and the patient was treated with inetetamab,pyrotinib,and capecitabine.Whole-brain radiotherapy was recommended.The patient and her family refused radiotherapy for personal reasons.In September 2021,a routine examination revealed that the brain tumor was considerably larger.The original systemic treatment was continued and combined with intensity-modulated radiation therapy for brain metastases,followed by regular hospitalization and routine examinations.The patient’s condition is generally stable,and she has a relatively high quality of life.This case report demonstrates that in patients with BCBM and resistance to trastuzumab,inetetamab combined with pyrotinib and chemotherapy can prolong survival.CONCLUSION Inetetamab combined with small molecule TKI drugs,chemotherapy and radiation may be an effective regimen for maintaining stable disease in patients with BCBM.

Effect of fibrinolytic therapy on ST-elevation myocardial infarction clinical outcomes during the COVID-19 pandemic:A systematic review and meta-analysis

BACKGROUND ST-elevation myocardial infarction(STEMI)is the result of transmural ischemia of the myocardium and is associated with a high mortality rate.Primary percutaneous coronary intervention(PPCI)is the recommended first-line treatment strategy for patients with STEMI.The timely delivery of PPCI became extremely challenging for STEMI patients during the coronavirus disease 2019(COVID-19)pandemic,leading to a projected steep rise in mortality.These delays were overcome by the shift from first-line therapy and the development of modern fibrinolytic-based reperfusion.It is unclear whether fibrinolytic-based reperfusion therapy is effective in improving STEMI endpoints.AIM To determine the incidence of fibrinolytic therapy during the COVID-19 pandemic and its effects on STEMI clinical outcomes.METHODS PubMed,Google Scholar,Scopus,Web of Science,and Cochrane Central Register of Controlled Trials were queried from January 2020 up to February 2022 to identify studies investigating the effect of fibrinolytic therapy on the prognostic outcome of STEMI patients during the pandemic.Primary outcomes were the incidence of fibrinolysis and the risk of all-cause mortality.Data were meta-analyzed using the random effects model to derive odds ratios(OR)and 95%confidence intervals.Quality assessment was carried out using the Newcastle-Ottawa scale.RESULTS Fourteen studies including 50136 STEMI patients(n=15142 in the pandemic arm;n=34994 in the pre-pandemic arm)were included.The mean age was 61 years;79%were male,27%had type 2 diabetes,and 47%were smokers.Compared with the pre-pandemic period,there was a significantly increased overall incidence of fibrinolysis during the pandemic period[OR:1.80(1.18 to 2.75);I2=78%;P=0.00;GRADE:Very low].The incidence of fibrinolysis was not associated with the risk of all-cause mortality in any setting.The countries with a low-and middle-income status reported a higher incidence of fibrinolysis[OR:5.16(2.18 to 12.22);I2=81%;P=0.00;GRADE:Very low]and an increased risk of all-cause mortality in STEMI patients[OR:1.16(1.03 to 1.30);I2=0%;P=0.01;GRADE:Very low].Meta-regression analysis showed a positive correlation of hyperlipidemia(P=0.001)and hypertension(P<0.001)with all-cause mortality.CONCLUSION There is an increased incidence of fibrinolysis during the pandemic period,but it has no effect on the risk of all-cause mortality.The low-and middle-income status has a significant impact on the all-cause mortality rate and the incidence of fibrinolysis.

Effects of oxygen therapy on the outcome of patients with acute myocardial infarction:A randomized clinical trial

Objective:To investigate the therapeutic effects of supplemental oxygen on patients with myocardial infarction.Methods:This study was a randomized,double-blind clinical trial.The study population included all patients who were admitted to the emergency room of Ali-ibn-Abitaleb and Khatam-al-Anbia hospitals in Zahedan within six hours of the onset of classic symptoms of myocardial infarction.The patients(n=47)were divided into two groups:the case group(with oxygen therapy)and the control group(without oxygen therapy).The initial follow-up was evaluated after one month and the second follow-up was evaluated after three months in the target population in terms of mortality caused by acute myocardial infarction,mortality caused by any other cause,and re-hospitalization caused by acute myocardial infarction.Results:Out of the 47 patients,27 were male(57.4%).The average age of the patients was(60.9±8.1)years.One month after admission,2 patients(8.7%)in the case group and 2 patients(8.3%)in the control group died due to acute myocardial infarction.A total of 7 patients(14.9%)died three months after admission.There was no significant difference between the control and case groups in terms of mortality caused by acute ischemia within one and three months.After one month,2 patients(8.7%)in the case group and 1 patient(4.2%)in the control group died of other causes.After three months,4 patients(8.5%)in total died for other causes.There was no significant difference between the control and case groups in terms of mortality due to other causes within one and three months.One month after admission,5 patients(21.7%)of the case group and 4 patients(16.7%)of the control group were re-hospitalized due to acute myocardial ischemia.During the next three months,3 patients(13.0%)of the case group and 5 patients(20.8%)of the control group were re-hospitalized.There was no significant difference between the control and case groups regarding the rate of re-hospitalization caused by acute myocardial infarction within one and three months after admission.Conclusions:There is no significant relationship between oxygen therapy and death by acute myocardial ischemia,or any other causes.The relationship between oxygen therapy and the rate of re-hospitalization caused by acute myocardial ischemia is not found within one and three months after admission.The results show that oxygen therapy does not affect patients with acute myocardial ischemia within three months after admission.

Brain and spinal cord trauma:what we know about the therapeutic potential of insulin growth factor 1 gene therapy

Although little attention has been paid to cognitive and emotional dysfunctions observed in patients after spinal co rd injury,several reports have described impairments in cognitive abilities.Our group also has contributed significantly to the study of cognitive impairments in a rat model of spinal co rd injury.These findings are very significant because they demonstrate that cognitive and mood deficits are not induced by lifestyle changes,drugs of abuse,and combined medication.They are related to changes in brain structures involved in cognition and emotion,such as the hippocampus.Chronic spinal cord injury decreases neurogenesis,enhances glial reactivity leading to hippocampal neuroinflammation,and trigge rs cognitive deficits.These brain distal abnormalities are recently called te rtiary damage.Given that there is no treatment for Tertiary Damage,insulin growth factor 1 gene therapy emerges as a good candidate.Insulin growth factor 1 gene thera py recove rs neurogenesis and induces the polarization from pro-inflammato ry towards anti-inflammatory microglial phenotypes,which represents a potential strategy to treat the neuroinflammation that supports te rtiary damage.Insulin growth factor 1 gene therapy can be extended to other central nervous system pathologies such as traumatic brain injury where the neuroinflammatory component is crucial.Insulin growth factor 1 gene therapy could emerge as a new therapeutic strategy for treating traumatic brain injury and spinal cord injury.

Cardioprotection and pharmacological therapies in acute myocardial infarction: Challenges in the current era

In patients with an acute ST-segment elevation myocardial infarction, timely myocardial reperfusion using primary percutaneous coronary intervention is the most effective therapy for limiting myocardial infarct size, preserving left-ventricular systolic function and reducing the onset of heart failure. Within minutes after the restoration of blood flow, however, reperfusion itself results in additional damage, also known as myocardial ischemia-reperfusion injury. An improved understanding of the pathophysiological mechanisms underlying reperfusion injury has resulted in the identification ofseveral promising pharmacological(cyclosporin-A, exenatide, glucose-insulin-potassium, atrial natriuretic peptide, adenosine, abciximab, erythropoietin, metoprolol and melatonin) therapeutic strategies for reducing the severity of myocardial reperfusion injury. Many of these agents have shown promise in initial proofof-principle clinical studies. In this article, we review the pathophysiology underlying myocardial reperfusion injury and highlight the potential pharmacological interventions which could be used in the future to prevent reperfusion injury and improve clinical outcomes in patients with coronary heart disease.

Resuscitating acupuncture therapy for glucose metabolism in acute cerebral infarction of basal ganglia

BACKGROUND： Acupuncture can improve motor function in patients with cerebral infarction, and activate brain glucose metabolism in relevant brain areas. However, the association between encephalic region activation and acupuncture, as well as the clinical significance of activation remain unclear. OBJECTIVE： Through the use of positron emission tomography-computed tomography （PET-CT）, acute cerebral infarction patients were analyzed for global cerebral metabolism, cerebral infarction focus, peripheral edema, and pyramidal tract pathway changes, which were directly related to clinical symptoms. The influence of resuscitating acupuncture on cerebral glucose metabolism was analyzed in patients with acute cerebral infarction in basal ganglia. DESIGN, TIME AND SETTNG： Randomized, controlled, clinical trials were performed from March 2007 to October 2008 at the PET-CT Center of the General Hospital of Tianjin Medical University, China. PARTICIPANTS： Twelve patients with acute basal ganglia infarction were recruited from the First Affiliated Hospital of Tianjin University of Traditional Chinese Medicine, the Second Affiliated Hospital of Tianjin University of Traditional Chinese Medicine, Tianjin Chinese Medicine Hospital, and Affiliated Hospital of Medical College of Chinese People＇s Armed Police Force. METHODS： The cerebral infarcted patients were randomly assigned to acupuncture and control groups. In addition to routine treatment, the acupuncture group was treated by acupuncture at the main acupoints for resuscitation [Neiguan （PC 6）, Renzhong （DU 26）, and Sanyinjiao （SP 6）], while the control group received routine treatment. MAIN OUTCOME MEASURES： Before and after treatment, patients with acute cerebral infarction were evaluated for global brain, cerebral infarction focus, and surrounding edema and glucose metabolism in encephalic region of pyramidal tract conduction by 18-labeled fluorodeoxyglucose for PET-CT imaging. RESULTS： The resuscitating acupuncture therapy can significantly activate the metabolism of global brain, infarction center and surrounding edema in patients with cerebral infarction in basal ganglia, also has effects on the activation of glucose metabolism in the encephalic regions of pyramidal tract pathway （P 〈 0.05）. CONCLUSION： Resuscitating acupuncture was superior to routine treatment for significantly activating glucose metabolism in patients with acute cerebral basal ganglia infarction.

Effect of medical care linkage-continuous management mode in patients with posterior circulation cerebral infarction undergoing endovascular interventional therapy

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.

Long-Term Prognosis of Different Reperfusion Strategies for ST-Segment Elevation Myocardial Infarction in Chinese County-Level Hospitals:Insight from China Acute Myocardial Infarction Registry

Objective To evaluate the long-term prognosis of patients with ST-segment elevation myocardial infarction(STEMI)treated with different reperfusion strategies in Chinese county-level hospitals Methods A total of 2,514 patients with STEMI from 32 hospitals participated in the China Acute Myocardial Infarction registry between January 2013 and September 2014.The success of fibrinolysis was assessed according to indirect measures of vascular recanalization.The primary outcome was 2-year mortality.Results Reperfusion therapy was used in 1,080 patients(42.9%):fibrinolysis(n=664,61.5%)and primary percutaneous coronary intervention(PCI)(n=416,38.5%).The most common reason for missing reperfusion therapy was a prehospital delay>12 h(43%).Fibrinolysis[14.5%,hazard ratio(HR):0.59,95%confidence interval(CI)0.44–0.80]and primary PCI(6.8%,HR=0.32,95%CI:0.22–0.48)were associated with lower 2-year mortality than those with no reperfusion(28.5%).Among fibrinolysistreated patients,510(76.8%)achieved successful clinical reperfusion;only 17.0%of those with failed fibrinolysis underwent rescue PCI.There was no difference in 2-year mortality between successful fibrinolysis and primary PCI(8.8%vs.6.8%,HR=1.53,95%CI:0.85–2.73).Failed fibrinolysis predicted a similar mortality(33.1%)to no reperfusion(33.1%vs.28.5%,HR=1.30,95%CI:0.93–1.81).Conclusion In Chinese county-level hospitals,only approximately 2/5 of patients with STEMI underwent reperfusion therapy,largely due to prehospital delay.Approximately 30%of patients with failed fibrinolysis and no reperfusion therapy did not survive at 2 years.Quality improvement initiatives are warranted,especially in public health education and fast referral for mechanical revascularization in cases of failed fibrinolysis.

Fifteen years of bone marrow mononuclear cell therapy in acute myocardial infarction

In spite of modern treatment, acute myocardial infarction(AMI) still carries significant morbidity and mortality worldwide. Even though standard of care therapy improves symptoms and also long-term prognosis of patients with AMI, it does not solve the critical issue, specifically the permanent damage of cardiomyocytes. As a result, a complex process occurs, namely cardiac remodeling, which leads to alterations in cardiac size, shape and function. This is what has driven the quest for unconventional therapeutic strategies aiming to regenerate the injured cardiac and vascular tissue. One of the latest breakthroughs in this regard is stem cell(SC) therapy. Based on favorable data obtained in experimental studies, therapeutic effectiveness of this innovative therapy has been investigated in clinical settings. Of various cell types used in the clinic, autologous bone marrow derived SCs were the first used to treat an AMI patient, 15 years ago. Since then, we have witnessed an increasing body of data as regards this cutting-edge therapy. Although feasibility and safety of SC transplant have been clearly proved, it's efficacy is still under dispute. Conducted studies and meta-analysis reported conflicting results, but there is hope for conclusive answer to be provided by the largest ongoing trial designed to demonstrate whether this treatment saves lives. In the meantime, strategies to enhance the SCs regenerative potential have been applied and/or suggested, position papers and recommendations have been published. But what have we learned so far and how can we properly use the knowledge gained? This review will analytically discuss each of the above topics, summarizing the current state of knowledge in the field.

Bridging therapy and direct mechanical thrombectomy in the treatment of cardiogenic cerebral infarction with anterior circulation macrovascular occlusion

BACKGROUND Intravenous thrombolysis is an important treatment for cerebral infarction.However,it is difficult to achieve good results if the patient is complicated with anterior circulation macrovascular occlusion.In addition,the vascular recanalization rate is low,so mechanical thrombectomy,that is,bridging therapy,is needed AIM To investigate the efficacy and safety of bridging therapy and direct mechanical thrombectomy in the treatment of cardiogenic cerebral infarction with anterior circulation macrovascular occlusion.METHODS Ninety-six patients in our hospital with cardiogenic cerebral infarction with anterior circulation macrovascular occlusion from January 2017 to July 2020 were divided into a direct thrombectomy group(n=48)and a bridging group(n=48).Direct mechanical thrombectomy was performed in the direct thrombectomy group,and bridging therapy was used in the bridging treatment group.Comparisons were performed for the treatment data of the two groups(from admission to imaging examination,from admission to arterial puncture,from arterial puncture to vascular recanalization,and from admission to vascular recanalization),vascular recanalization rate,National Institutes of Health Stroke Scale(NIHSS)and Glasgow Coma Scale(GCS)scores before and after treatment,prognosis and incidence of adverse events.RESULTS In the direct thrombectomy group,the time from admission to imaging examination was 24.32±8.61 min,from admission to arterial puncture was 95.56±37.55 min,from arterial puncture to vascular recanalization was 54.29±21.38 min,and from admission to revascularization was 156.88±45.51 min,and the corresponding times in the bridging treatment group were 25.38±9.33 min,100.45±39.30 min,58.14±25.56 min,and 161.23±51.15 min;there were no significant differences between groups(P=0.564,0.535,0.426,and 0.661,respectively).There was no significant difference in the recanalization rate between the direct thrombectomy group(79.17%)and the bridging group(75.00%)(P=0.627).There were no significant differences between the direct thrombectomy group(16.69±4.91 and 12.12±2.07)and the bridging group(7.13±1.23) and(14.40±0.59)in preoperative NIHSS score and GCS score(P=0.200 and 0.203,respectively).After the operation,the NIHSS scores in both groups were lower than those before the operation,and the GCS scores were higher than those before the operation.There was no significant difference in NIHSS and GCS scores between the direct thrombectomy group(6.91±1.10 and 14.19±0.65)and the bridging group(7.13±1.23 and 14.40±0.59)(P=0.358 and 0.101,respectively).There was no significant difference in the proportion of patients who achieved a good prognosis between the direct thrombectomy group(52.08%)and the bridging group(50.008%)(P=0.838).There was no significant difference in the incidence of adverse events between the direct thrombectomy group(6.25%)and the bridging group(8.33%)(P=0.913).CONCLUSION Bridging therapy and direct mechanical thrombectomy can safely treat cardiogenic cerebral infarction with anterior circulation macrovascular occlusion,achieve good vascular recanalization effects and prognoses,and improve the neurological function of patients.

Effect of reperfusion strategy on QT dispersion in patients with acute myocardial infarction:Impact on in-hospital arrhythmia

BACKGROUND Myocardial ischemia and ST-elevation myocardial infarction(STEMI)increase QT dispersion(QTD)and corrected QT dispersion(QTcD),and are also associated with ventricular arrhythmia.AIM To evaluate the effects of reperfusion strategy[primary percutaneous coronary intervention(PPCI)or fibrinolytic therapy]on QTD and QTcD in STEMI patients and assess the impact of the chosen strategy on the occurrence of in-hospital arrhythmia.METHODS This prospective,observational,multicenter study included 240 patients admitted with STEMI who were treated with either PPCI(group I)or fibrinolytic therapy(group II).QTD and QTcD were measured on admission and 24 hr after reperfusion,and patients were observed to detect in-hospital arrhythmia.RESULTS There were significant reductions in QTD and QTcD from admission to 24 hr in both group I and group II patients.QTD and QTcD were found to be shorter in group I patients at 24 hr than those in group II(53±19 msec vs 60±18 msec,P=0.005 and 60±21 msec vs 69+22 msec,P=0.003,respectively).The occurrence of in-hospital arrhythmia was significantly more frequent in group II than in group I(25 patients,20.8%vs 8 patients,6.7%,P=0.001).Furthermore,QTD and QTcD were higher in patients with in-hospital arrhythmia than those without(P=0.001 and P=0.02,respectively).CONCLUSION In STEMI patients,PPCI and fibrinolytic therapy effectively reduced QTD and QTcD,with a higher observed reduction using PPCI.PPCI was associated with a lower incidence of in-hospital arrhythmia than fibrinolytic therapy.In addition,QTD and QTcD were shorter in patients not experiencing in-hospital arrhythmia than those with arrhythmia.

Modified constraint-induced movement therapy enhances cortical plasticity in a rat model of traumatic brain injury:a resting-state functional MRI study

Modified constraint-induced movement therapy(mCIMT)has shown beneficial effects on motor function improvement after brain injury,but the exact mechanism remains unclear.In this study,amplitude of low frequency fluctuation(ALFF)metrics measured by resting-state functional magnetic resonance imaging was obtained to investigate the efficacy and mechanism of mCIMT in a control co rtical impact(CCI)rat model simulating traumatic brain injury.At 3 days after control co rtical impact model establishment,we found that the mean ALFF(mALFF)signals were decreased in the left motor cortex,somatosensory co rtex,insula cortex and the right motor co rtex,and were increased in the right corpus callosum.After 3 weeks of an 8-hour daily mClMT treatment,the mALFF values were significantly increased in the bilateral hemispheres compared with those at 3 days postoperatively.The mALFF signal valu es of left corpus callosum,left somatosensory cortex,right medial prefro ntal cortex,right motor co rtex,left postero dorsal hippocampus,left motor cortex,right corpus callosum,and right somatosensory cortex were increased in the mCIMT group compared with the control cortical impact group.Finally,we identified brain regions with significantly decreased mALFF valu es at 3 days postoperatively.Pearson correlation coefficients with the right forelimb sliding score indicated that the improvement in motor function of the affected upper limb was associated with an increase in mALFF values in these brain regions.Our findings suggest that functional co rtical plasticity changes after brain injury,and that mCIMT is an effective method to improve affected upper limb motor function by promoting bilateral hemispheric co rtical remodeling.mALFF values correlate with behavio ral changes and can potentially be used as biomarkers to assess dynamic cortical plasticity after traumatic brain injury.

Anxiety Network of Brain Function in Patients with Acute Cerebral Infarction

Objective: To explore the characteristics of brain functional network with anxiety in patients with acute cerebral infarction. Methods: A total of 39 patients with acute cerebral infarction by cranial magnetic resonance examination were included, and all the patients were scored by the Hamilton Anxiety Scale. The anxiety scale is scored by a professional psychiatrist. There are a total of 14 items, including anxiety, nervousness, fear, insomnia, cognitive function, depressed mood, somatic anxiety, sensory system, etc. The total score ≥ 29 points may be severe;≥21 points, there must be obvious;≥14 points, there must be anxiety;a score of more than 7 may indicate anxiety. If the score is less than 7, there are no anxiety symptoms. All patients within 24 to 72 hours, complete the head examination magnetic resonance, computerized calculation of the DWI sequence images, according to the results of the calculation to superimpose the image of the lesion, image reconstruction in space, and carry out Binarization, defining the value of lesions as 1, and the value of non as 0. All lesions are superimposed into one image and integrated. The relationship between the lesions in this superimposed image and anxiety after cerebral infarction was analyzed. Results: The lesions were basically concentrated around the lateral ventricle, and they were mainly concentrated around the lateral ventricle. Conclusion: Patients with acute cerebral infarction in the lateral ventricle or basal ganglia are more prone to post-stroke anxiety. This has a certain evaluation value for the prognosis of future cerebral infarction, and has a certain understanding of the exploration of complications, and has a certain understanding of the exploration of complications.

Silent brain infarctions and leuko-araiosis in Chinese patients with first-ever acute lacunar strokes

We report on silent brain infarction (SBI) and leuko- araiosis (LA) of 23 patients with clinically diagnosed “first-ever” acute ischemic lacunar stroke. The lacunar syndromes were pure motor hemiparesis (10), pure sensory syndrome (2), ataxic hemiparesis (3), dysarthria clumsy hand syndrome (3), and sensory- motor deficit (5). Nineteen out of the 23 patients presented with completed strokes on arrival to the hospital, and 4 (17%) developed evolving-stroke within 24 hours of stroke onset. A lacune corresponded to the acute stroke could be found in all patients on brain magnetic resonance imaging (MRI), and in 18 (78%) on brain computed tomography (CT). MRI showed additional subclinical or asymptomatic “silent brain infarctions or lacunes” (SBI) in 19 (83%) of 23 patients, and leuko-araiosis (LA) of moderate to severe degree (> grade 2) was present in 61% of patients although dementia was absent. Hypertension is the risk factor in 78% of cases followed by diabetes mellitus, smoking, and elevated plasma cholesterol level. Independence of the types of lacunar syndromes, patients with hypertension and diabetes mellitus are associated with high grade LA. None with normal blood pressure and plasma glucose had grade 3 or grade 4 LA (p < 0.05). In conclusion, evolving-stroke occurs in one- fifth of patients with “first-ever” lacunar infarct within the first 24 hours of stroke onset. SBI was found in 83% of cases. Hypertension and diabetes mellitus are associated with additional SBI and high grade LA. The severity of leuko-araiosis per se dictates the cerebrovascular risks.

Clinical study of recombinant human brain natriuretic peptide in patients with acute myocardial infarction complicating congestive heart failure

Objectives To observe the efficacy and safety of recombinant human brain natriuretic peptide(rh-BNP) on patients with acute myocardial infarction complicating congestive heart failure.Methods 40 patients with acute myocardial infarction complicated by congestive heart failure were randomly divided into control group and treatment group of 20 cases.The control group,15 cases of acute anterior myocardial infarction,5 cases of acute inferior wall myocardial infarction, 15 males and 5 females,aged 55-70 years,mean age 58±12 years;treated 16 cases of acute anterior myocardial infarction,4 cases of acute myocardial infarction,16 males and 4 females,aged 56-70 years,mean age 59±11 years;two groups of age,gender,severity of disease and vascular lesions no significant difference and comparable(P】0.05).Conventional group were given aspirin,clopidogrel, statins,Inotropic,diuretic and vasodilator therapy.In the con- ventional treatment group based on the use of recombinant human brain natriuretic peptide(new bios,Tibet Pharmaceutical Co.,Ltd.Chengdu Nuodikang biopharmaceutical production, usage:1.5μg/Kg intravenous injection(impact), then 0.0075μg-0.01μg/(kg·min)infusion rate).Continuous medication 72 h.The clinical symptoms observed for 3 days in patients before treatment and after treatment,heart rate,blood pressure and left ventricular ejection fraction (LVEF) and tumor necrosis factor(TNF-α),brain natriuretic peptide(BNP) levels were measured.Results In control group,8 cases markedly effect,5 cases effect and 7 cases no effect,the total effective rate was 65%;In treatment group,13 cases markedly effect,6 cases effect and 1 cases no effect,the total effective rate was 95%,compared with two groups P New bios treatment group significantly increased cardiac index(CI) in patients with heart failure and left ventricular ejection fraction(LVEF) than the control group(all P【0.05),further reduce the levels of tumor necrosis (TNF-α) and brain natriuretic peptide(BNP).Conclusions rh-BNP can improve symptoms and heart function,reduced plasma tumor necrosis factor(TNF-α) and BNP levels of acute myocardial infarction patients with congestive heart failure,the treatment safe and reliable.As small sample size observed,larger sample to be accumulated to further evaluate its efficacy and safety.
