Conclusion: The application of VOJTA therapy in the treatment of children with cerebral palsy can not only promote the rehabilitation of gross motor function, but also help to improve the treatment effect, and the earlier the treatment, the better.

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.

Clinical Study on Improving Articulation Clarity in Spastic Cerebral Palsy with 120 Cases of Oral-Facial Acupressure Combined with Oral Placement Therapy

Objective:To observe the efficacy of oral-facial acupressure combined with oral placement therapy(OPT)in improving articulation clarity in 120 children with spastic cerebral palsy,and to explore effective therapeutic solutions for speech disorders associated with spastic cerebral palsy.Methods:A total of 120 children with spastic cerebral palsy and speech disorders,meeting the inclusion criteria,were randomly assigned into two groups:60 cases in the treatment group and 60 cases in the control group.The treatment group received orofacial acupressure combined with OPT,while the control group received only OPT.The Oral Motor Function Assessment Scale(OMFAS),developed by the China Rehabilitation Research Centre(CRRC),was used to evaluate the treatment outcomes before and after the intervention.Results:After the treatment,both the treatment and control groups showed improved mobility of the mandible,lips,and tongue.However,the treatment group exhibited significantly better improvement than the control group,with the difference between the two groups being statistically significant(P<0.05).Conclusion:Oral-facial acupressure combined with OPT can effectively improve articulation clarity in children with spastic cerebral palsy.This combined therapy is recommended for clinical promotion and application.

Modified constraint-induced movement therapy alters synaptic plasticity of rat contralateral hippocampus following middle cerebral artery occlusion

Modified constraint-induced movement therapy is an effective treatment for neurological and motor impairments in patients with stroke by increasing the use of their affected limb and limiting the contralateral limb.However,the molecular mechanism underlying its efficacy remains unclear.In this study,a middle cerebral artery occlusion(MCAO)rat model was produced by the suture method.Rats received modified constraint-induced movement therapy 1 hour a day for 14 consecutive days,starting from the 7^th day after middle cerebral artery occlusion.Day 1 of treatment lasted for 10 minutes at 2r/min,day 2 for 20 minutes at 2 r/min,and from day 3 onward for 20 minutes at 4 r/min.CatWalk gait analysis,adhesive removal test,and Y-maze test were used to investigate motor function,sensory function as well as cognitive function in rodent animals from the 1st day before MCAO to the 21^st day after MCAO.On the 21^st day after MCAO,the neurotransmitter receptor-related genes from both contralateral and ipsilateral hippocampi were tested by micro-array and then verified by western blot assay.The glutamate related receptor was shown by transmission electron microscopy and the glutamate content was determined by high-performance liquid chromatography.The results of behavior tests showed that modified constraint-induced movement therapy promoted motor and sensory functional recovery in the middle cerebral artery-occluded rats,but had no effect on cognitive function.The modified constraint-induced movement therapy upregulated the expression of glutamate ionotropic receptor AMPA type subunit 3(Gria3)in the hippocampus and downregulated the expression of the beta3-adrenergic receptor gene Adrb3 and arginine vasopressin receptor 1 A,Avprla in the middle cerebral artery-occluded rats.In the ipsilateral hippocampus,only Adra2 a was downregulated,and there was no significant change in Gria3.Transmission electron microscopy revealed a denser distribution the more distribution of postsynaptic glutamate receptor 2/3,which is an a-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid receptor,within 240 nm of the postsynaptic density in the contralateral cornu ammonis 3 region.The size and distribution of the synaptic vesicles within 100 nm of the presynaptic active zone were unchanged.Western blot analysis showed that modified constraint-induced movement therapy also increased the expression of glutamate receptor 2/3 and brain-derived neurotrophic factor in the hippocampus of rats with middle cerebral artery occlusion,but had no effect on Synapsin I levels.Besides,we also found modified constraint-induced movement therapy effectively reduced glutamate content in the contralateral hippocampus.This study demonstrated that modified constraint-induced movement therapy is an effective rehabilitation therapy in middle cerebral artery-occluded rats,and suggests that these positive effects occur via the upregulation of the postsynaptic membrane a-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid receptor expression.This study was approved by the Institutional Animal Care and Use Committee of Fudan University,China(approval No.201802173 S)on March 3,2018.

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.

Combined treatment using acupuncture and music therapy on children with cerebral palsy Gross motor function measure comparison in 60 cases

BACKGROUND： The use of acupuncture has received recognition to effectively treat cerebral palsy. Moreover, music therapy can be used to modify treatment of cerebral palsy. OBJECTIVE： To study the effects of combined treatment using acupuncture and music therapy on gross motor function measure （GMFM） of children with cerebral palsy, compared with acupuncture treatment alone. DESIGN, TIME AND SETTING： Randomized, controlled, clinical study. The experiment was conducted in Shenzhen Hospital of Traditional Chinese Medicine between January 2007 and September 2007. PARTICIPANTS： All children with cerebral palsy in the trial were from the outpatient department of Shenzhen Hospital of Traditional Chinese Medicine. The children were randomly divided into two groups： 30 children in Group B received acupuncture and music therapy, while 30 children in Group A received only acupuncture therapy. METHODS： Subjects in Groups A and B received acupuncture based on syndrome differentiation. The main acupoints were necessary for all participants. At first, flash needling was applied to the acupoints. For the remaining acupoints, the technique of transverse needling was applied to the head acupoints, and perpendicular needling was used for the other points. The inserted needles were twirled and then maintained for 30 minutes. The needle was twirled for one second every other 10 minutes, without reinforcing-reducing techniques. The therapy was performed every other day. The trial consisted of three periods each, and lasted for 84 days. Subjects in Group B received music therapy. They listened to music that they preferred while acupuncture was being performed. Following acupuncture, they were allowed to perform musical activities, such as percussion, singing, and dancing. The music therapy was scheduled for one hour, including listening to music for 30 minutes and music activities for 30 minutes. MAIN OUTCOME MEASURES： The comprehensive functional evaluation scale of cerebral palsy and the GMFM were applied to test symptoms before and after respective treatment. RESULTS： All 60 children were included in final analysis. The general function of all children with cerebral palsy improved, but the general efficiency in Group B was obviously higher than in Group A （93% and 73%, Х^2 = 4.32, P 〈 0.05）. GMFM evaluation showed that the function of crawling and kneeling, standing, and walking improved more significantly in Group B than in Group A （P 〈 0.05）, while the function of lying down, rolling, and sitting remained similar between the two groups （P 〉 0.05）. CONCLUSION： The combination of acupuncture and music therapy on the treatment of cerebral palsy is more effective than acupuncture alone. The various activities in music therapy may affect treatment of cerebral palsy.

Therapies for children with cerebral palsy A Web of Science-based literature analysis

OBJECTIVE： To identify global research trends in three therapies for children with cerebral palsy. DATA RETRIEVAL： We performed a bibliometric analysis of studies on therapies for children with cerebral palsy from 2002 to 2011 retrieved from Web of Science. SELECTION CRITERIA： Inclusion criteria： （a） peer-reviewed published articles on botulinum toxin, constraint-induced movement therapy, or acupuncture for children with cerebral palsy indexed in Web of Science; （b） original research articles, reviews, meeting abstracts, proceedings papers, book chapters, editorial material, and news items; and （c） publication between 2002 and 2011. Exclusion criteria： （a） articles that required manual searching or telephone access; （b） documents that were not published in the public domain; and （c） a number of corrected papers from the total number of articles. MAIN OUTCOME MEASURES： （1） Number of publications on the three therapies; （2） annual publication output, distribution by journals, distribution by institution, and top-cited articles on botulinum toxin; （3） annual publication output, distribution by journal, distribution by institution, and top-cited articles on constraint-induced movement therapy; （4） annual publication, distribution by journal, distribution by institution, and top-cited articles on acupuncture. RESULTS： This analysis, based on Web of Science articles, identified several research trends in studies published over the past 10 years of three therapies for children with cerebral palsy. More articles on botulinum toxin for treating children with cerebral palsy were published than the articles regarding constraint-induced movement therapy or acupuncture. The numbers of publications increased over the 10-year study period. Most papers appeared in journals with a focus on neurology, such as Developmental Medicine and Child Neurology and Journal of Child Neurology.Research institutes publishing on botulinum toxin treatments for this population are mostly in the Netherlands, the United States of America, and Australia; those publishing on constraint-induced movement therapy are mostly in Australia and the United States of America; and those publishing on acupuncture are mostly in China, Sweden and the United States of America.CONCLUSION： Analysis of literature and research trends indicated that there was no one specific therapy to cure cerebral palsy. Further studies are still necessary.

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.

Hypertensive-Nimodipine Therapy for Middle Cerebral Artery Vasospasm after Resection of Glioblastoma Multiforme: A Case Report and Literature Review

Delayed cerebral ischemia (DCI) due to post-brain tumor resection vasospasm is an often unrecognized yet debilitating complication. We present a patient with DCI after the resection of glioblastoma multiforme (GBM). To our knowledge, this is the first report on DCI after GBM resection. A 52-year-old female patient with headache for one month underwent subtotal resection of a left temporal GBM encasing the proximal middle cerebral artery (MCA). She was well during the immediate postoperative period but developed right upper limb dense monoparesis on postoperative day four with computed tomographic angiography confirming left MCA vasospasm. Symptoms were significantly alleviated with weeklong hypertensive therapy and nimodipine administration;however they recurred soon after cessation of treatment. A high index of clinical suspicion is needed for the diagnosis of post-tumor resection DCI. Any new postoperative neurological deficit that cannot be explained by hemorrhage, seizures or infection should be expeditiously investigated by angiography or transcranial Doppler sonography. Prompt initiation of hypertensive and nimodipine therapy can possibly reverse neurological deficit. Treatment should be guided by Doppler, angiographic or perfusion imaging studies and not by clinical improvement alone.

~1H-magnetic resonance spectroscopy screening for animals with acute cerebral infraction suitable forthrombolytic therapy

BACKGROUND： As a non-invasive technique which can provide comprehensive biological information, 1H-magnetic resonance spectroscopy （1H-MRS） may provide valuable reference data for irreversible recovery or reversible changes in ischemic tissue after stroke. OBJECTIVE： To monitor and evaluate the effect of the urokinase thrombolytic therapy after experimental acute cerebral ischemia by 1H-MRS technology and investigate its adaptability. DESIGN： Randomly controlled animal study. SETTINGS： Shenzhen Hospital of Peking University and National Key Laboratory of Pattern and Atom ＆ Molecular Physics, Wuhan Physics and Mathematics Institute, Chinese Academy of Science. MATERIALS： Eleven healthy adult Sprague-Dawley （SD） rats, weighing 260–300 g and of both genders, were supplied by Experimental Animal Center of Tongji Medical Collage, Huazhong University of Science and Technology [SCXK （e） 2004-007]. 4.7T superconducting nuclear magnetic resonance meter was provided by Brucker Company. METHODS： The experiment was carried out in Shenzhen Hospital of Peking University and National Key Laboratory of Pattern and Atom ＆ Molecular Physics, Wuhan Physics and Mathematics Institute, Chinese Academy of Science from August 2003 to December 2005. ① The rats were randomly divided into 30-minute self-thrombo-embolism group （n =6） and 60-minute self-thrombo-embolism group （n =5）. Six rats in 30-minute self-thrombo-embolism group were occluded with clot embolus for 30 minutes and 5 rats in 60-minute self-thrombo-embolism group were occluded for 60 minutes. 10 000 U/kg urokinase was dissolved in 2 mL saline and the operation lasted for 5 minutes. ② 1H-MRS was performed before thrombolysis and at 3 hours and 24 hours after successful embolization. The metabolic changes of N-acetyl-L-aspartic acid （NAA）/phosphocreatine （PCr） ＋ creatine （Cr）, choline phosphate （Cho）/PCr＋Cr and lactic acid （Lac）/PCr＋Cr in the region of interests were analyzed. ③ The T2W image was conducted 24 hours after the thrombolytic therapy with TR=500 ms and TE=25 ms. ④ The subjects were sacrificed immediately after 1H-MRS and the brain tissues were cut into pieces and stained with HE method; in addition, pathological changes were observed under optic microscope. MAIN OUTCOME MEASURES： ① Metabolic changes of NAA/PCr＋Cr, Cho/PCr＋Cr and Lac/PCr＋Cr in the region of interests; ② T2W image at 24 hours after the thrombolysis; ③ pathological observation of brain tissue. RESULTS： Eleven rats were all involved in the final analysis. ① Metabolic changes in the region of interests ： In 30-minute self-thrombo-embolism group, the Lac peak emerged immediately after the embolism, but the ischemic zone decreased 3 hours after the thrombolytic therapy （0.252±0.01, 0.603±0.01, P 〈 0.01）. Lac/（PCr＋Cr） ratio was 0.290±0.01 at 24 hours after thrombolysis, which was higher than that at 3 hours after thrombolysis （P 〈 0.01）. The NAA/ （PCr＋Cr） ratio decreased significantly at 3 hours after the thrombolysis as compared with that before thrombolysis （0.922±0.16, 1.196±0.01, P 〈 0.05）. In 60-minute self-thrombo-embolism group, the Lac/（PCr＋Cr） ratio was higher at 3 hours after thrombolysis than that before thrombolysis （0.846±0.12, 0.601±0.11, P 〈 0.05） and the NAA/（PCr＋Cr） decreased at 3 hours after the embolism. Fluctuation of NAA/ （PCr＋Cr） ranged from 0.68 to 0.75 before thrombolysis and from 0.71 to 0.75 at 3 hours after thrombolysis. ② T2W image： T2W image showed that 2 subjects in 30-minute self-thrombo-embolism group whose Lac/NAA was higher than 0.7 suffered from intracranial hemorrhage. This meant that the subjects with Lac/NAA 〉 0.7 were more likely to suffer from intracranial hemorrhage. ③ Histological and morphological examinations： Optic microscope demonstrated that interspace surrounding nerve cells was widened at ischemic center; neurons were swelling; nucleus was stained lightly; pyknosis and mesenchymal edema were mainly observed in lateral cortex of brow and vertex and in lateralpart of corpus striatum. CONCLUSION： ①Compound parameters in ischemic area before thrombolysis should be regarded as an important predicting marker for thrombolytic therapy, effect evaluation and termination. ② 1H-MRS combining with other imaging technique is a detecting way for screening cases who are suitable for thrombolytic therapy.

Evolving of treatment options for cerebral infarction

In this editorial,we comment on a recent article which addressed the therapeutic effect of aspirin plus edaravone in patients with cerebral infarction(CI).Herein,we outline the progress in therapy of CI.Apart from thrombolysis,aspirin is the most effective treatment for CI.Edaravone,a free radical scavenger,reduces endothelial cell damage and delays neuronal cell death.Aspirin plus edaravone mitigates damage to brain tissue by different mechanisms,thereby expediting the reinstation of neurological function.However,the nephrotoxic effect of edaravone,along with gastrointestinal bleeding associated with aspirin,may restrict this combination therapy.Although clinical studies have demonstrated the efficacy of thrombolytic therapy and mechanical thrombectomy,patients receiving these treatments experience modest efficacy and many adverse events.Moreover,interest in exploring natural medicines for CI is increasing,and they appear to have a high potential to protect against CI.The evolution of therapeutic strategies is expected to improve clinical outcomes of patients with CI.

Use of MLC901 in cerebral venous sinus thrombosis:Three case reports

BACKGROUND Cerebral venous sinus thrombosis(CVT)is rare cause of cerebrovascular disease.The incidence is 0.5%of all stroke.The majority of affected patients are young adults(mean age:35-40 years)with mild to moderate disabilities.Poor outcome with severe disability is seen in 13%of cases.Early diagnosis and treatment are important for good outcomes and preventing complications.Treatment options are limited and mostly based on consensus.NeuroAiD II™(MLC901;Moleac Pte,Ltd,Singapore)has a potential beneficial role in post-stroke recovery,by aiding the natural brain recovery process.CASE SUMMARY MLC901 consists of nine natural herbal ingredients.Studies have shown its safety profile and aid in post stroke recovery.The aim of this case series was to demonstrate the potential role of MLC901 in stroke recovery of patients with cerebral venous sinus thrombosis(CVST)who received MLC901 in addition to standard of care.The prescribed dose of MLC901 is 400 mg/cap two capsules,three times a day.Data from these patients were prospectively collected at baseline and at monthly visits,for a duration of 3 mo.Outcome measures included adherence to therapy,side effects,National Institutes of Health Stroke Scale,Glasgow Coma Scale,modified Rankin Scale,and the Short Orientation-Memory-Concentration Test.MLC901 was well tolerated and no side effects were reported.All patients were stable with improved condition.CONCLUSION This case series highlights the potential therapeutic effects of MLC901 on CVST and provides support for further studies.

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.

Left ventricular thrombosis caused cerebral embolism during venoarterial extracorporeal membrane oxygenation support: A case report

BACKGROUND Venoarterial(VA)extracorporeal membrane oxygenation(ECMO),an effective short-term circulatory support method for refractory cardiogenic shock,is widely applied.However,retrospective analyses have shown that VA-ECMO-assisted cases were associated with a relatively high mortality rate of approximately 60%.Embolization in important organs caused by complications of left ventricular thrombosis(LVT)during VA-ECMO is also an important reason.Although the incidence of LVT during VA-ECMO is not high,the consequences of embolization are disastrous.CASE SUMMARY A 37-year-old female patient was admitted to hospital because of fever for 4 d and palpitations for 3 d.After excluding the diagnosis of coronary heart disease,we established a diagnosis of“clinically explosive myocarditis”.The patient still had unstable hemodynamics after drug treatment supported by VA-ECMO,with heparin for anticoagulation.On day 4 of ECMO support,a left ventricular thro-mbus attached to the papillary muscle root of the mitral valve was found by transthoracic echocardiography.Left ventricular decompression was performed and ECMO was successfully removed,but the patient eventually died of multiple cerebral embolism.CONCLUSION LVT with high mobility during VA-ECMO may cause embolism in important organs.Therefore,a"wait and see"strategy should be avoided.

Edaravone-loaded poly(amino acid) nanogel inhibits ferroptosis for neuroprotection in cerebral ischemia injury

Neurological injury caused by ischemic stroke is a major cause of permanent disability and death. The currently available neuroprotective drugs fail to achieve desired therapeutic efficacy mainly due to short circulation half-life and poor blood−brain barrier (BBB) permeability. For that, an edaravone-loaded pH/glutathione (pH/GSH) dual-responsive poly(amino acid) nanogel (NG/EDA) was developed to improve the neuroprotection of EDA. The nanogel was triggered by acidic and EDA-induced high-level GSH microenvironments, which enabled the selective and sustained release of EDA at the site of ischemic injury. NG/EDA exhibited a uniform sub-spherical morphology with a mean hydrodynamic diameter of 112.3 ± 8.2 nm. NG/EDA efficiently accumulated at the cerebral ischemic injury site of permanent middle cerebral artery occlusion (pMCAO) mice, showing an efficient BBB crossing feature. Notably, NG/EDA with 50 µM EDA significantly increased neuron survival (29.3%) following oxygen and glucose deprivation by inhibiting ferroptosis. In addition, administering NG/EDA for 7 d significantly reduced infarct volume to 22.2% ± 7.2% and decreased neurobehavioral scores from 9.0 ± 0.6 to 2.0 ± 0.8. Such a pH/GSH dual-responsive nanoplatform might provide a unique and promising modality for neuroprotection in ischemic stroke and other central nervous system diseases.

Autologous Stem Cell Therapy for Cerebral Palsy

Introduction: We describe treatment of Cerebral Palsy with adult stem cells derived from bone marrow and fat of the same patient. Adult stem cells are of two types, the mesenchymal and haemopoietic stem cells which have potential to duplicate, indefinitely produce 50 types of growth factors that repair and regenerate tissues in an epigenetic manner. Every organ has its own stem cells, for example kidney stem cells, liver stem cells, etc. When specialized cells in an organ get damaged, the local stem cells come forward and get differentiated into specialized cells and the tissue damage is replenished. But when the stock of this reserve of local stem cell is over, the organ starts failing. In autologous stem cell therapy, we harvest stem cells from other healthy organs like fat and bone marrow which have abundant stem cells and put them into the diseased organ. Adult stem cells differentiate into neurons in vitro when added with nerve growth factor which is present in every nerve tissue. Our stem cell research was done by following all the guidelines set at national and international level. In India the incidence of cerebral palsy is around 5/1000 live births. In cerebral Palsy the upper motor neuron is weak, hence the lower motor neuron becomes hyper active leading to spasticity. The treatment involves mainly physiotherapy and prognosis is poor. Physiotherapy is a palliation and does not repair damage in the brain. The conventional therapy has failed to give any satisfactory results in these children hence something new needs to be done. Materials and Methods: In last 2 years we did stem cell therapy for 21 cases of CP in our center with age of 9 months to 17 years. Out of 21 cases of CP, 7 (33.3%) cases had quadriplegia, 6 (28.57%) paraplegia and 1 (4.76%) monoplegia, 2 (9%) hypotonic, 5 (23.8%) hemiplegia, 4 (19.04%) with mental retardation and 3 (14.28) had features of ADHD and Autism. 18 patients had squint in the eyes, 8 patients had food regurgitation and drooling of saliva, 2 patients had audiovisual impairment, 3 patients had bronchial asthma and one patient had menstrual irregularity. 26 cases were put as control with age range of 9 months to 19 years. 9 (34.61%) patients had quadriplegia, 8 (30.76%) paraplegia and 3 (11.53) had monoplegia, 3 (11.53%) hypotonic, 5 (19.23) with mental retardation and 6 (23.07) had features of ADHD and autism. 21 patients had squint in the eyes, 11 patients had food regurgitation and drooling of saliva, 4 patients had audiovisual impairment, 5 patients had bronchial asthma in the control group. 11 patients were subjected to adipose tissue derived stem cell therapy and 10 with bone marrow derived stem cell therapy. All patients were examined at 3 monthly intervals. Maximum follow up was 2.5 years and minimum of one year. Results: The results of bone marrow derived stem cells and adipose tissue derived stem cells were almost the same. Results took 3 months to appear and positive outcome came till one year since therapy. The spasticity was significantly reduced in 15 out of 18 patients in 6 months. Out of 18 patients who had squint, it was regressed completely in 12 (66.66%) patients and partially in 3 (16.66%) in 6 months’ time. 8 patients had faulty deglutition and 75% of them had 90%

ACUPUNCTURE THERAPY AND POINT-INJECTION OF MEDICINE FOR TREATMENT OF 32 CASES OF INFANTILE CEREBRAL PALSY

In the present study, 32 cases of infantile cerebral palsy were treated with acupunc-ture and point-injection therapies. Among them, 15 cases were cured basicaly, 7 markedly efec-tive, 9 improved and 2 failed, with a total effective rate being 93. 8%. The results showed thatthe therapies both could improve the microcirculation of the brain tissues in favour of recovery ofcerebral functions.

Effect of adjuvant therapy with ginkgo-damole on apoptosis, nerve injury and platelet aggregation of patients with acute cerebral infarction

Objective:To investigate the effect of adjuvant therapy with ginkgo-damole on apoptosis, nerve injury and platelet aggregation of patients with acute cerebral infarction. Methods:A total of 74 patients with acute cerebral infarction treated in our hospital from March 2014 to December 2015 were retrospectively analyzed, and they were divided into ginkgo-damole group and conventional treatment group according to a therapeutic schedule that whether ginkgo-diyidamolum were included. At Week 2 and Week 4 after treatment, contents of apoptosis molecule, nerve injury molecule and index of platelet aggregation in serum were detected. Results:At Week 2 after treatment, contents of soluble Fas, soluble Fas ligand, soluble tumor necrosis factor related apoptosis inducing ligand, S100β, neuron specific enolase, glial fibrillary acidic protein, myelin basic protein, malonaldehyde, endothelin-1, fibrinogen and D-dimer in patients' sera of ginkgo-damole group were significantly lower than those of conventional treatment group. Contents of nitric oxide in sera were obviously higher than that of conventional treatment group. At Week 4 after treatment, contents of soluble Fas, soluble Fas ligand, soluble tumor necrosis factor related apoptosis inducing ligand, S100β, neuron specific enolase, glial fibrillary acidic protein, myelin basic protein, malonaldehyde, endothelin-1, fibrinogen and D-dimer in patients' sera of ginkgo-damole group were significantly lower than those of conventional treatment group. Contents of nitric oxide in sera were obviously higher than that of conventional treatment group. Conclusions:Adjuvant therapy with ginkgo-damole can inhibit the apoptosis of neuron cells and neurogliocyte and reduce the neural function injury and the situation of platelet aggregation.

Effects of ganglioside + aspirin + atorvastatin triple therapy on oxidative stress and inflammatory response in patients with cerebral infarction

Objective: To investigate the effects of ganglioside + aspirin + atorvastatin triple therapy on oxidative stress and inflammatory response in patients with cerebral infarction. Methods:A total of 138 patients with acute cerebral infarction between July 2016 and July 2017 were divided into control group (n=69) and triple group (n=69) by random number table method. Control group accepted conventional symptomatic treatment combined with aspirin and atorvastatin therapy, triple group accepted conventional symptomatic treatment combined with ganglioside, aspirin and atorvastatin triple therapy, and both groups were treated for 1 month. The differences in oxidative stress and inflammatory response were compared between the two groups before and after treatment. Results: Immediately after admission, There was no statistically significant difference in serum levels of oxidative stress indexes and inflammatory mediators between the two groups. After 1 week of treatment and after 4 weeks of treatment, serum oxidative stress indexes ROS and AOPPs levels of triple group were lower than those of control group whereas SOD and CAT contents were higher than those of control group;serum inflammatory mediators IL-6, TNF-α and TGF-β levels were lower than those of control group whereas IL-4, IL-10 and IL-13 levels were higher than those of control group. Conclusion: ganglioside + aspirin + atorvastatin triple therapy can effectively inhibit the systemic oxidative stress and inflammatory response in patients with cerebral infarction.
