In tropical countries like India,malaria has been one of the most common parasitic illnesses leading to frequent hospitalization and causing major economic burden among the masses. Although Plasmodium vivax infection is considered to be benign,in contrast to Plasmodium, falciparum infection which is notorious for its severe splenic complications can occur frequently. Splenomegaly tends not to receive special attention,as it is not usually accompanied by any symptoms and can be gradually resolved via standard antimalarial therapy.Splenic infarction, although rarely attributable to malaria in an endemic region with high parasitemia,can be a rare presentation of this disease entity. 展开更多

The present study enrolled a Chinese family that comprised 34 members and spanned three generations. Eight members were diagnosed with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy, and disease diagnoses corresponded with autosomal incomplete dominance inheritance. The primary clinical manifestations included paralysis, dysarthria, and mild cognitive deficits. Magnetic resonance imaging revealed diffuse leukoencephalopathy with involvement of bilateral anterior temporal lobes, in particular the pons. In addition, multiple cerebral infarction was identified in the proband. Sural nerve biopsy findings of the proband revealed granular osmophilic material deposits in the extracellular matrix, which were adjacent to smooth muscle cells of dermal arterioles. Screening exons 2-4 for NOTCH 3 mutations by direct sequencing did not reveal any abnormalities. 展开更多

Protective effect of catalpol on myocardium was studied in relation to endothelial progenitor cells, Notch1 signaling pathway and angiogenesis in rats with isoprenaline (INN)-induced acute myocardial infarcts. To analyze the pathological status and impact of catalpol on the rats, 3 weeks after intragastric gavage, the animals were verified for myocardial infarcts with electrocardiogram and measured for enzyme activity of lactate dehydrogenase (LDH), malondialdehyde (MDA), creatine kinase (CK) and superoxide dismutase (SOD) in myocardium, and further analyzed using HE and TTC staining, as well as visual examination of infarct area. Flow cytometry study of endothelial progenitor cells (EPCs) indicated that the EPCs were mobilized during infarction. The roles of Notch1 signaling pathway in angiogenesis of the infracted animals were studied using immunohistochemistry analysis of RBPjκ and Western blot analysis of Notch1 and Jagged1. Our results obtained from the rats treated with catalpol, positive drug and control showed that catalpol could protect rats from infarction probably by mobilization of EPCs and activation of Notch1 signaling pathway. 展开更多

Objective To study the relationships between cognitive impairment in patients with lacunar infarcts and quantitative CT measures and to determine the independent correlative factors of cognitive impairment.Methods Neuropsychological examination was conducted for 128 patients with acute lacunar infarct.Number,location,and volume of infarcts,cerebral atrophy index and severity of white matter lesions(WMLs) were measured and recorded.Results The number of lacunar infarcts in cognitive impairment (CI) group was significantly larger than that in cognitive normal(CN) group.Mean width of sulcus and sylvian fissure,index of frontal horn and ventricular-brain ratio(VBR) were significantly different in both groups.There were more patients with 3 grades or 4 grades WMLs in CI group(62%) than those in CN group(22%).The total volume of lacunar infarcts showed no statistically significant difference.Logistic regression analysis indicated that the number of lacunar infarcts in frontal subcortex and thalamus,the volume of infarcts in anterior periventricular white matter,width of cerebral sulcus and sylvian fissure were correlated with cognitive impairment respectively.Additionally,age and education were correlative factors of cognitive impairment in patients with lacunar infarct.Conclusion Correlative factors of cognitive impairment in patients with lacunar infarct are not merely one feature,but a combination of infarct features(number,location,and volume),cortical atrophy and host factors(age and education). 展开更多

Exogenous stem cell transplantation and endogenous stem cell mobilization are both effective for the treatment of acute cerebral infarction. The compound dl-3-butylphthalide is known to improve microcirculation and help brain cells at the infarct loci. This experiment aimed to investigate the effects of dl-3-butylphthalide intervention based on the transplantation of hematopoietic stem cells and mobilization of endogenous stem cells in a rat model of cerebral infarction, following middle cerebral artery occlusion. Results showed that neurological function was greatly improved and infarct volume was reduced in rats with cerebral infarction. Data also showed that dl-3-butylphthalide can promote hematopoietic stem cells to transform into vascular endothelial cells and neuronal-like cells, and also enhance the therapeutic effect on cerebral infarction by hematopoietic stem cell transplantation and endogenous stem cell mobilization. 展开更多

BACKGROUND Idiopathic omental infarction(IOI)is challenging to diagnose due to its low incidence and vague symptoms.Its differential diagnosis also poses difficulties because it can mimic many intra-abdominal organ pathologies.Although hypercoagulability and thrombosis are among the causes of omental infarction,venous thromboembolism scanning is rarely performed as an etiological investigation.CASE SUMMARY The medical records of the 5 cases,who had the diagnosis of IOI by computed tomography,were examined.The majority of the patients were male(n=4,80%)and the mean age was 31 years(range:21-38).The patients had no previous abdominal surgery or a history of any chronic disease.The main complaint of all patients was persistent abdominal pain.Omental infarction was detected in all patients with contrast-enhanced computed tomography.Conservative treatment was initially preferred in all patients,but it failed in 1 patient(20%).After discharge,all patients were referred to the hematology department for thrombophilia screening.Only 1 patient applied for thrombophilia screening and was homozygous for methylenetetrahydrofolate reductase(A1298C mutation)and heterozygous for a factor V Leiden mutation.CONCLUSION IOI should be considered in the differential diagnosis in patients presenting with progressive and/or persistent right side abdominal pain.Investigating risk factors such as hypercoagulability in patients with IOI is also important in preventing future conditions related to venous thromboembolism. 展开更多

Accurate and automatic segmentation of hyper-acute ischemic infarct from magnetic resonance imaging is of great importance in clinical trials. Manual delineation is labor intensive, exhibits great variability due to unclear infarct boundaries, and most importantly, is not practical due to urgent time requirement for prompt therapy. In this paper, segmentation of hyper-acute ischemic infarcts from diffusion weighted imaging based on Support Vector Machine (SVM) is explored. Experiments showed that SVM could provide good agreement with manual delineations by experienced experts to achieve an average Dice coefficient of 0.7630.121. The proposed method could achieve significantly higher segmentation accuracy and could be a potential tool to assist clinicians for quantifying hyper-acute infarction and decision making especially for thrombolytic therapy. 展开更多

Objectives Endovascular therapy(EVT)now penetrates the once obscure realm of large infarct core volume acute ischaemic stroke(LICV-AIS).This research aimed to investigate the potential correlation between different anaesthetic approaches and post-EVT outcomes in LICV-AIS patients.Methods Between October 2020 and May 2022,the China ANGEL-Alberta Stroke Programme Early CT Score(ASPECT)trial studied patients with LICV-AIS,randomly assigning them to the best medical management(BMM)or BMM with EVT.This post hoc subgroup analysis categorised subjects receiving BMM with EVT into general anaesthesia(GA)and non-GA groups based on anaesthesia type.We applied multivariable logistic regression to evaluate the relationship between anaesthesia during EVT and patient functional outcomes,as measured by the modified Rankin scale(mRS),in addition to the occurrence of complications.Further adjustment for selection bias was achieved through propensity score matching(PSM).Results In total,230 patients with LICV-AIS were enrolled(GA 84 vs Non-GA 146).No significant difference was observed between the two groups in terms of the proportion of patients who achieved an mRS score of 0-2 at 90 days(27.4%for the GA group vs 31.5%for the non-GA group,p=0.51).However,the GA group had significantly longer median surgical times(142 min vs 122 min,p=0.03).Furthermore,GA was associated with an increased risk of postoperative pneumonia(adjusted OR 2.03,95%CI 1.04 to 3.98).The results of PSM analysis agreed with the results of the multivariate regression analysis.No significant difference in intracranial haemorrhage incidence or mortality rate was observed between the groups.Conclusion This post hoc analysis of subgroups of the ANGEL-ASPECT trial suggested that there may be no significant association between the choice of anaesthesia and neurological outcomes in LICV-AIS patients.However,compared with non-GA,GA prolongs the duration of EVT and is associated with a greater postoperative pneumonia risk. 展开更多

Background: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a hereditar5 small artery disease caused by NOTCH3 gene mutation. We performed enhanced depth imaging optical coherence tomography (EDI-OCT) to evaluate the retinal vessel changes in CADASIL patients and assessed their consonance with brain magnetic resonance imaging (MPRI) findings. Methods: Of 27 genetically confirmed patients and an equal number of controls were recruited at the Peking University First ttospital from January 2015 to August 2016. All patients underwent 7T-MRI of the brain. Fazekas score, number of small infarcts and microblecds were evaluated. All patients and controls underwent EDI-OCT to measure subtbveal choroidal thickness (SFCT), inner and outer diameters as well as arterial and venous wall thickness, and arterial venous ratio of the inner (AVRin) and outer diameters (AVRout). The relation between retinal vessel changes and Fazekas scores, numbers of small infarcts, or microbleeds was analyzed. Paired t-test was used to compare the SFCT and retinal vessel measurement data between patients and controls. Spearman's correlation was used to investigmc the correlation between retinal vessel changes and MRI lesions. Results: In CADASI L patients, mean SFCT (268.37 ± 46.50 μm) and mean arterial inner diameter (93.46 ± 9.70 gin) were signilicantly lower than that in controls (P 〈 0.00 ), P = 0.048, respectively). Mean arterial outer diameter ( 131.74 ± 10.87 μm), venous inner ( 128.99 ± 13.62 μm) and outer diameter ( 164.82 ±14.77 μm), and mean arterial ( 19.13 ±1.85 μm) and venous ( 17.91 ±2.76 μm) wall thickness were significantly higher than that in controls (P = 0.023, P 0.004, P 〈 0.001, P 〈 0.001, respectively). Arterial inner diameter (r= - 0.39, P 0.044)] AVRin (r -0.65, P 〈 0.001), and AVR,, (r =0.56, P - 0.002) showed a negative correlation with the number of small infarcts. Venous inner diameter (rs=0.46, P= 0.016) showed a positive correlation with the number of small infarcts. Venous inner diameter (r 0.59, P = 0.002), outer diameter (rs=0.47, P= 0.017), showed a positive correlation with the number of cerebral microbleeds (CM Bs). AVRin (r =0.52, P = 0.007) and AVRout (r = -0.40, P =0.048) showed a negative correlation with the number of CMBs. Conclusions: Measurement of retinal vessels using EDI-OCT correlates moderately well with MRI parameters. EDI-OCT might bc a useful evaluation tool for CADASIL patients. 展开更多

Stroke,particularly ischemic stroke,is the leading cause of long-term disability and mortality worldwide.It occurs due to the occlusion of the cerebral arteries,which significantly reduces the delivery of blood,oxygen,and essential nutrients to brain tissues.This deprivation triggers a cascade of cellular events that ultimately leads to neuronal death.Recent studies have clarified the multifactorial pathogenesis of ischemic stroke,highlighting the roles of energy failure,excitotoxicity,oxidative stress,neuroinflammation,and apoptosis.This review aimed to provide a comprehensive insight into the fundamental mechanisms driving neuronal death triggered by ischemia and to examine the progress of neuroprotective therapeutic approaches designed to mitigate neuronal loss and promote neurological recovery after a stroke.Additionally,we explored widely accepted findings regarding the potential pathways implicated in neuronal death during ischemic stroke,including the interplay of apoptosis,autophagy,pyroptosis,ferroptosis,and necrosis,which collectively influence neuronal fate.We also discussed advancements in neuroprotective therapeutics,encompassing a range of interventions from pharmacological modulation to stem cell-based therapies,aimed at reducing neuronal injury and enhancing functional recovery following ischemic stroke.Despite these advancements,challenges remain in translating mechanistic insights into effective clinical therapies.Although neuroprotective strategies have shown promise in preclinical models,their efficacy in human trials has been inconsistent,often due to the complex pathology of ischemic stroke and the timing of interventions.In conclusion,this review synthesizes mechanistic insights into the intricate interplay of molecular and cellular pathways driving neuronal death post-ischemia.It sheds light on cutting-edge advancements in potential neuroprotective therapeutics,underscores the promise of regenerative medicine,and offers a forward-looking perspective on potential clinical breakthroughs.The ongoing evolution of precision-targeted interventions is expected to significantly enhance preventative strategies and improve clinical outcomes. 展开更多

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL), is the most common cause of inherited cerebral small vessel disease, inherited stroke and inherited vascular dementia. It is not infrequent for CADASIL to be mistaken and mistreated for multiple sclerosis (MS). A much less frequent but existing scenario is the co-occurrence of CADASIL and MS (or MS-like inflammatory condition). Such patients may present with spinal cord lesions, brain or spinal cord enhancing lesions, positive oligoclonal bands and high IgG index in the cerebrospinal fluid and good response to corticosteroids or immunomodulating treatments. CADASIL through various mechanisms may trigger or modulate autoimmune reactions, and either be complicated by an inflammatory component or cause an MS-like disorder. 展开更多

Exogenous neural stem cell transplantation has become one of the most promising treatment methods for chronic stroke.Recent studies have shown that most ischemia-reperfusion model rats recover spontaneously after injury,which limits the ability to observe long-term behavioral recovery.Here,we used a severe stroke rat model with 150 minutes of ischemia,which produced severe behavioral deficiencies that persisted at 12 weeks,to study the therapeutic effect of neural stem cells on neural restoration in chronic stroke.Our study showed that stroke model rats treated with human neural stem cells had long-term sustained recovery of motor function,reduced infarction volume,long-term human neural stem cell survival,and improved local inflammatory environment and angiogenesis.We also demonstrated that transplanted human neural stem cells differentiated into mature neurons in vivo,formed stable functional synaptic connections with host neurons,and exhibited the electrophysiological properties of functional mature neurons,indicating that they replaced the damaged host neurons.The findings showed that human fetal-derived neural stem cells had long-term effects for neurological recovery in a model of severe stroke,which suggests that human neural stem cells-based therapy may be effective for repairing damaged neural circuits in stroke patients. 展开更多

Regulatory T cells are crucial immunomodulatory cells that play essential roles in both ischemic stroke and intracerebral hemorrhage.These cells are vital in post-stroke inflammation since they suppress immune responses and promote tissue repair.This review thoroughly examines the dynamic changes in the number and function of regulatory T cells and highlights their distinct roles at various stages of stroke progression.In the acute phase(within 5-7 days),regulatory T cells exert neuroprotective effects primarily by reducing inflammation.In the chronic phase(7 days post-onset),these cells support neuroregeneration and functional recovery.The review also explores the emerging role of regulatory T cells in the brain-gut axis,a key mediator of the systemic immune responses following stroke,and discusses its relevance in modulating post-stroke inflammation and repair.Various strategies aimed at enhancing regulatory T cell responses include adoptive transfer of regulatory T cells,administration of pharmacological agents,and induction of mucosal tolerance.All these approaches can potentially enhance the immunomodulatory and repair functions of regulatory T cells.Nevertheless,despite the promising preclinical results,the translation of regulatory T cell-based therapies into clinical practice is associated with challenges related to optimal timing,dosage,and long-term efficacy.Overall,targeting regulatory T cells is a novel and promising immunoregulatory approach for mitigating stroke-induced injury and promoting neural repair. 展开更多

Background:Myocardial infarction(MI)remains a major global public health challenge.Although advances in reperfusion therapy have reduced acute mortality,post-infarction cardiac remodeling continues to pose a substantial threat to long-term cardiovascular health.Oxidative stress and the ensuing inflammatory response are key drivers of this pathological process,leading to cardiomyocyte death,myocardial fibrosis,and functional impairment.Among the regulatory pathways involved,the kelch-like ECH-associated protein 1(Keap1)/nuclear factor erythroid 2-related factor 2(Nrf2)axis has emerged as a critical therapeutic target for mitigating post-MI cardiac injury.Methods:A murine MI model was established by permanent ligation of the left anterior descending coronary artery.Mice received oral Tongxinbi formula(TXB)at low,medium,or high doses(9/18/36 g/kg)once daily for 28 days.Cardiac function was assessed by echocardiography;myocardial fibrosis by Masson’s trichrome;and endothelial integrity by CD31 immunofluorescence.Plasma markers of endothelial function and inflammation were quantified.In vitro,oxidative stress was induced by H2O2 in vascular endothelial cells and cardiomyocytes,followed by treatment with TXB drug-containing serum.Western blot and RT-qPCR were used to measure components of the Keap1/Nrf2 pathway;ELISA quantified oxidative stress and inflammatory indices.Conditioned-medium experiments evaluated endothelial cell–mediated paracrine protection of cardiomyocytes.Results:TXB significantly improved cardiac function and reduced myocardial fibrosis after MI,in association with preservation of microvascular structure and systemic attenuation of oxidative stress and inflammation.In vitro,TXB activated the endothelial Keap1/Nrf2 pathway,enhanced cellular antioxidant defenses,increased VEGF secretion,and,via endothelial cell-mediated paracrine signaling,alleviated cardiomyocyte injury under oxidative stress.Conclusion:TXB exerts anti-fibrotic and cardioprotective effects by activating Nrf2 signaling and engaging endothelial-mediated paracrine mechanisms,collectively mitigating oxidative stress and inflammation in the post-MI setting. 展开更多

Background:Data on the evolution of recent small sub-cortical infarcts are limited,especially in the Chinese.Previous studies have reported a large heterogeneity in cavitation and infarct location;therefore,the present study assessed the morphology of small subcortical infarcts in the basal ganglia in a Chinese cohort.Methods:Patients who had experienced a recent,single,small sub-cortical infarct in the basal ganglia and received at least one follow-up magnetic resonance imaging(MRI)scan were retrospectively identified from January 2014 to June 2018.Time to followup imaging,baseline infarct size,vascular risk factors,and other clinical data,as well as the morphologic changes of the index infarct and surrounding white matter were recorded.Demographic,clinical and MRI characteristics were respectively compared among three groups(white matter hyper-intensitie[WMH]vs.cavitation vs.absent)and between with and without new WMH formation groups.In addition,logistic regression analyses were performed in investigating the determinate independent predictors for new WMH formation.Results:Seventy-eight subjects were included with a median follow-up time of 304 days(range:124–552 days).We found a significant reduction in infarct size at follow-up:46 of 78(59.0%)infarctions showed some degree of cavitation,19 of 78(24.4%)index lesions resembled non-cavitated WMH,and 13 of 78(16.7%)infarcts had disappeared at follow-up MRI.No factors were found to be associated with differential outcomes of the infarcts.In addition,8 of 78(10.3%)patients demonstrated new WMH formation surrounding the index infarct;white matter progression(odds ratio=15.95,95%confidence interval=1.65–153.99;P=0.017)was an independent risk factor of new WMH formation.Conclusions:More than half of the small sub-cortical infarcts in the basal ganglia progressed to cavities,demonstrating that these infarcts can be reduced and go undetected.The presence of new WMH around the infarct may be indicative of the worsening progression of cerebral small vessel diseases.Additionally,white matter progression is an independent risk factor,which may be a potential therapeutic target. 展开更多

This case reports a presentation of multiple cerebellar infarcts.The 42-year-old male patient presented to the emergency department with a 3-day history of dizziness accompanied by speech abnormalities,visual rotation,nausea,and vomiting without other complaints.Imaging studies,particularly a diffusion-weighted magnetic resonance imaging,confirmed acute cerebral infarction in both cerebellar hemispheres,cerebellar vermis,and ventral side of the left pons,with swelling in the left cerebellar hemisphere and compression in the fourth ventricle and medulla oblongata,as well as the softening lesions in the right lateral ventricle,left parietal occipital lobe,and pontine.This case highlights those multiple cerebellar infarcts are often small,with or without larger territorial infarcts,despite complexity,and the timely diagnosis and intervention are of great importance. 展开更多

Objective This study aimed to investigate the impact of glycemic control and diabetes duration on subsequent myocardial infarction(MI)in patients with both coronary heart disease(CHD)and type 2 diabetes(T2D).Methods We conducted a retrospective cohort study of 33,238 patients with both CHD and T2D in Shenzhen,China.Patients were categorized into 6 groups based on baseline fasting plasma glucose(FPG)levels and diabetes duration(from the date of diabetes diagnosis to the baseline date)to examine their combined effects on subsequent MI.Cox proportional hazards regression models were used,with further stratification by age,sex,and comorbidities to assess potential interactions.Results Over a median follow-up of 2.4 years,2,110 patients experienced MI.Compared to those with optimal glycemic control(FPG<6.1 mmol/L)and shorter diabetes duration(<10 years),the fullyadjusted hazard ratio(HR)(95%Confidence Interval[95%CI])for those with a diabetes duration of≥10 years and FPG>8.0 mmol/L was 1.93(95%CI:1.59,2.36).The combined effects of FPG and diabetes duration on MI were largely similar across different age,sex,and comorbidity groups,although the excess risk of MI associated with long-term diabetes appeared to be more pronounced among those with atrial fibrillation.Conclusion Our study indicates that glycemic control and diabetes duration significant influence the subsequent occurrence of MI in patients with both CHD and T2D.Tailored management strategies emphasizing strict glycemic control may be particularly beneficial for patients with longer diabetes duration and atrial fibrillation. 展开更多

Objective: To explore the therapeutic effect of Huoxue Tongmai capsule combined with edaravone right camphor on patients with acute cerebral infarction (Acute Cerebral Infarction) and the effect of combination therapy on serum inflammatory factors. Methods: In this study, 90 patients with acute cerebral infarction hospitalized in Zhuji People’s Hospital from December 2023 to December 2024 were selected and divided into two groups of 45 patients in each group. The control group used standard medical treatment, and the treatment group compared the changes of serum inflammatory factors IL-CRP, TNF-α, and Hcy with Huoxue Tongmai capsule for 7 days, 14 days and 30 days, and discussed the changes of the modified Rankin scale score (mRS) and National Institutes of Health Stroke Scale (NIHSS) score. Results: At 7 days, 14 days, and 30 days of treatment, the NIHSS score, mRS score, hs-CRP, IL-6, TNF-α, and Hcy levels were statistically significant (P α, and Hcy levels in the treatment group were significantly lower than those in the control group (P Conclusion: Patients with acute cerebral infarction received Huoxue Tongmai capsule combined with edaravone right camphor, which can reduce the inflammatory reaction, improve the nerve function and improve the prognosis. 展开更多
