文摘The current animal models of stroke primarily model a single intracerebral hemorrhage(ICH)attack,and there is a lack of a reliable model of recurrent ICH.In this study,we established 16-month-old C57 B L/6 male mouse models of ICH by injecting collagenaseⅦ-S into the left striatum.Twenty-one days later,we injected collagenaseⅦ-S into the right striatum to simulate recurrent ICH.Our results showed that mice subjected to bilateral striatal hemorrhage had poorer neurological function at the early stage of hemorrhage,delayed recovery in locomotor function,motor coordination,and movement speed,and more obvious emotional and cognitive dysfunction than mice subjected to unilate ral striatal hemorrhage.These findings indicate that mouse models of bilateral striatal hemorrhage can well simulate clinically common recurrent ICH.These models should be used as a novel tool for investigating the pathogenesis and treatment targets of recurrent ICH.

文摘Purpose:The aim of the current study was to investigate the association of accelerometer-measured sleep duration and different intensities of physical activity(PA)with the risk of incident type 2 diabetes in a population-based prospective cohort study.Methods:Altogether,88,000 participants(mean age=62.2±7.9 years,mean±SD)were included from the UK Biobank.Sleep duration(short:<6 h/day;normal:6-8 h/day;long:>8 h/day)and PA of different intensities were measured using a wrist-won accelerometer over a 7-day period between 2013 and 2015.PA was classified according to the median or World Health Organization-recommendation:total volume of PA(high,low),moderate-to-vigorous PA(MVPA)(recommended,not recommended),and light-intensity PA(high,low).Incidence of type 2diabetes was ascertained using hospital records or death registries.Results:During a median follow-up of 7.0 years,1615 incident type 2 diabetes cases were documented.Compared with normal sleep duration,short(hazard ratio(HR)=1.21,95%confidence interval(95%CI):1.03-1.41)but not long sleep duration(HR=1.01,95%CI:0.89-1.15)was associated with excessive type 2 diabetes risk.This increased risk among short sleepers seems to be protected against by PA.Compared with normal sleepers with high or recommended PA,short sleepers with low volume of PA(HR=1.81,95%CI:1.46-2.25),not recommended(below the World Health Organization-recommended level of)MVPA(HR=1.92,95%CI:1.55-2.36),or low light-intensity PA(HR=1.49,95%CI:1.13-1.90)had a higher risk of type 2 diabetes,while short sleepers with a high volume of PA(HR=1.14,95%CI:0.88-1.49),recommended MVPA(HR=1.02,95%CI:0.71-1.48),or high light-intensity PA(HR=1.14,95%CI:0.92-1.41)did not.Conclusion:Accelerometer-measured short but not long sleep duration was associated with a higher risk of incident type 2 diabetes.A higher level of PA,regardless of intensity,potentially ameliorates this excessive risk.

文摘Background:Diabetic nephropathy(DN)is a serious complication of diabetes with rising prevalence worldwide.We aimed to explore the anti-DN mechanisms of the compound celastrol derived from the medicinal plant Tripterygium wilfordii.Methods:Celastrol-related targets were obtained from Herbal Ingredients’Targets(HIT)and GeneCards databases.DN-related targets were retrieved from GeneCards,DisGeNET,and Therapeutic Targets Database(TTD).A Protein-protein interaction(PPI)network was established using the Search Tool for the Retrieval of Interacting Genes(STRING)database.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses were performed using ClusterProfiler.The cytoHubba plugin was used to select the top 10 hub targets.Molecular docking was performed employing PyMOL and AutoDock software.Cell counting kit-8(CCK-8)and flow cytometry assays were used to detect the viability and apoptosis of NRK-52E cells,respectively.The mRNA expression levels of mitogen-activated protein kinase 3(MAPK3),tumor necrosis factor(TNF),and AKT serine/threonine kinase 1(AKT1)in NRK-52E cells were assessed using quantitative real-time polymerase chain reaction(qRT-PCR).Results:We obtained sixty-six overlapping targets of celastrol and DN.GO and KEGG analyses demonstrated that the core targets of celastrol and DN were mainly involved in the inflammatory and immune response,oxidative stress,advanced glycation end products(AGEs)and their receptors(RAGEs)(AGE-RAGE),TNF,interleukin 17(IL-17),and MAPK signaling pathways.Finally,based on the good binding activity with celastrol,MAPK3,TNF,and AKT1 were identified as the foremost targets of celastrol.We observed that celastrol enhanced the viability of high glucose(HG)-treated NRK-52E cells and inhibited apoptosis in the in vitro assays.Moreover,celastrol decreased the mRNA expression levels of MAPK3,TNF,and AKT1 in high glucose(HG)-treated NRK-52E cells.Conclusion:Celastrol may treat DN by targeting APK3,TNF,and AKT1 and regulating inflammatory responses and oxidative stress through the AGE-RAGE,TNF,IL-17,and MAPK signaling pathways.

文摘Acute respiratory distress syndrome(ARDS)is a common and clinically devastating disease that causes respiratory failure.Morbidity and mortality of patients in intensive care units are stubbornly high,and various complications severely affect the quality of life of survivors.The pathophysiology of ARDS includes increased alveolar–capillary membrane permeability,an influx of protein-rich pulmonary edema fluid,and surfactant dysfunction leading to severe hypoxemia.At present,the main treatment for ARDS is mechanical treatment combined with diuretics to reduce pulmonary edema,which primarily improves symptoms,but the prognosis of patients with ARDS is still very poor.Mesenchymal stem cells(MSCs)are stromal cells that possess the capacity to self-renew and also exhibit multilineage differentiation.MSCs can be isolated from a variety of tissues,such as the umbilical cord,endometrial polyps,menstrual blood,bone marrow,and adipose tissues.Studies have confirmed the critical healing and immunomodulatory properties of MSCs in the treatment of a variety of diseases.Recently,the potential of stem cells in treating ARDS has been explored via basic research and clinical trials.The efficacy of MSCs has been shown in a variety of in vivo models of ARDS,reducing bacterial pneumonia and ischemia-reperfusion injury while promoting the repair of ventilator-induced lung injury.This article reviews the current basic research findings and clinical applications of MSCs in the treatment of ARDS in order to emphasize the clinical prospects of MSCs.

文摘Background Acute myocardial infarction(AMI)is a high-risk cardiovascular condition associated with increased cellular damage and oxidative stress.Aldo-Keto Reductase 1C3(AKR1C3)is a stress-regulating gene.Nevertheless,its specific role and mechanisms regarding AMI remain unclear.Methods We assessed cardiac function through echocardiography;tissue damage was evaluated using Hematoxylin and Eosin(HE)and Masson trichrome staining.AKR1C3 expression levels were measured through Reverse transcription-quantitative polymerase chain reaction and western blot.Assessed cell viability using Cell Counting Kit-8 and lactate dehydrogenase(LDH)assays.The extent of ferroptosis was determined by measuring the levels of Fe2+,boron-dipyrromethane(BODIPY)and malondialdehyde(MDA),the glutathione/glutathione disulfide(GSH/GSSG)ratio,and the expression of Glutathione Peroxidase 4(GPX4)and Solute carrier 7A11(SLC7A11).Kelch-like ECH-associated protein 1-Nuclear factor erythroid 2-related factor 2-Antioxidant response element(Keap1-Nrf2-ARE)pathway activation was analyzed through western blotting.Nrf2 was inhibited with ML385and activated with(R)-Sulforaphane to investigate the Keap1-Nrf2-ARE pathway.Results The rats in the AMI group displayed reduced heart function,more tissue damage,and lower AKR1C3 expression compared to the Sham group.Similarly,hypoxia-treated H9C2 cells showed reduced viability,and decreased AKR1C3 expression.Overexpressing AKR1C3 in H9C2 cells enhanced viability.Knocking down AKR1C3 exhibited the opposite effect.Of the inhibitors tested,Ferrostatin-1 most effectively restored cell viability in hypoxia-treated H9C2 cells.Moreover,H9C2 cells subjected to hypoxia suggested Keap1-Nrf2-ARE pathway inhibition.Overexpressing AKR1C3 reduced ferroptosis and activated the Keap1-Nrf2-ARE pathway in hypoxia-treated cells,knocking down AKR1C3 exhibited the opposite effect.Further experiments using ML385 in hypoxia-treated H9C2 cells with overexpressed AKR1C3 showed decreased viability and increased ferroptosis compared to the control.Using(R)-Sulforaphane in hypoxia-treated H9C2 cells with knocked-down AKR1C3 exhibited the opposite effect.Conclusion This study's findings indicate that AKR1C3 plays a role in regulating ferroptosis in myocardial cells,with the Keap1-Nrf2-ARE pathway likely being a key mechanism behind it.
文摘BACKGROUND Multiple primary carcinomas(MPCs)are defined as two or more independent primary cancers that occur simultaneously or sequentially in the same individual.Synchronous MPCs are rarer than solitary cancers or metachronous MPCs.Accurate diagnoses of synchronous MPCs and the choice of treatment are critical for successful outcomes in these cases.CASE SUMMARY A 64-year-old patient presented with dysphagia,without obvious cause.A diagnosis of synchronous esophageal squamous cell carcinoma and colon adenocarcinoma with liver metastasis was confirmed based on examination and laboratory results.After multi-disciplinary consultations,combination chemotherapy(a 3-wk cycle with oxaliplatin 212 mg administered on day 1 and capecitabine 1.5 g twice daily on days 1-14)and esophageal cancer radiotherapy were initiated.Based on the results of genetic testing,we switched to a regimen of leucovorin+fluorouracil+oxaliplatin and cetuximab regimen for 8 cycles.Subsequently,capecitabine and bevacizumab were administered until the most recent follow-up,at which the tumor remained stable.CONCLUSION Successful cetuximab chemotherapy treatment provides a reference for the nonoperative and homogeneous treatment of different pathological types of synchronous MCPs.

文摘BACKGROUND Intracranial atherosclerosis,a leading cause of stroke,involves arterial plaque formation.This study explores the link between plaque remodelling patterns and diabetes using high-resolution vessel wall imaging(HR-VWI).AIM To investigate the factors of intracranial atherosclerotic remodelling patterns and the relationship between intracranial atherosclerotic remodelling and diabetes mellitus using HR-VWI.METHODS Ninety-four patients diagnosed with middle cerebral artery or basilar artery INTRODUCTION Intracranial atherosclerotic disease is one of the main causes of ischaemic stroke in the world,accounting for approx-imately 10%of transient ischaemic attacks and 30%-50%of ischaemic strokes[1].It is the most common factor among Asian people[2].The adaptive changes in the structure and function of blood vessels that can adapt to changes in the internal and external environment are called vascular remodelling,which is a common and important pathological mechanism in atherosclerotic diseases,and the remodelling mode of atherosclerotic plaques is closely related to the occurrence of stroke.Positive remodelling(PR)is an outwards compensatory remodelling where the arterial wall grows outwards in an attempt to maintain a constant lumen diameter.For a long time,it was believed that the degree of stenosis can accurately reflect the risk of ischaemic stroke[3-5].Previous studies have revealed that lesions without significant luminal stenosis can also lead to acute events[6,7],as summarized in a recent meta-analysis study in which approximately 50%of acute/subacute ischaemic events were due to this type of lesion[6].Research[8,9]has pointed out that the PR of plaques is more dangerous and more likely to cause acute ischaemic stroke.Previous studies[10-13]have found that there are specific vascular remodelling phenomena in the coronary and carotid arteries of diabetic patients.However,due to the deep location and small lumen of intracranial arteries and limitations of imaging techniques,the relationship between intracranial arterial remodelling and diabetes is still unclear.In recent years,with the development of magnetic resonance technology and the emergence of high-resolution(HR)vascular wall imaging,a clear and multidimensional display of the intracranial vascular wall has been achieved.Therefore,in this study,HR wall imaging(HR-VWI)was used to display the remodelling characteristics of bilateral middle cerebral arteries and basilar arteries and to explore the factors of intracranial vascular remodelling and its relationship with diabetes.

文摘Background:Invasive Trichosporon asahii(T.asahii)infection frequently occurs with a high mortality in immunodeficient hosts,but the pathogenesis of T.asahii infection remains elusive.Circular RNAs(circRNAs)are a type of endogenous noncoding RNA that participate in various disease processes.However,the mechanism of circRNAs in T.asahii infection remains completely unknown.Methods:RNA sequencing(RNA-seq)was performed to analyze the expression profiles of circRNAs,microRNAs(miRNAs),and mRNAs in THP-1 cells infected with T.asahii or uninfected samples.Some of the RNA-seq results were verified by RT-qPCR.Gene Ontology(GO)enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analyses were used to analyze the differentially expressed mRNAs.A circRNA-miRNA-mRNA network was constructed and verified by dual-luciferase reporter assay and overexpression experiments.Results:A total of 46 circRNAs,412 mRNAs and 47 miRNAs were differentially expressed at 12 h after T.asahii infection.GO and KEGG analyses showed that the differentially expressed mRNAs were primarily linked to the leukocyte migration involved in the inflammatory response,the Toll-like receptor signaling pathway,and the TNF signaling pathway.A competing endogenous RNA(ceRNA)network was constructed with 5 differentially expressed circRNAs,5 differentially expressed miRNAs and 42 differentially expressed mRNAs.Among them,hsa_circ_0065336 was found to indirectly regulate PTPN11 expression by sponging miR-505-3p.Conclusions:These data revealed a comprehensive circRNA-associated ceRNA network during T.asahii infection,thus providing new insights into the pathogenesis of the T.asahii-host interactions.

文摘BACKGROUND Little is known about the postoperative sleep quality of infective endocarditis patients during hospitalization and after discharge.AIM To investigate the sleep characteristics of infective endocarditis patients and to identify potential risk factors for disturbed sleep quality after surgery.METHODS The Pittsburgh Sleep Quality Index(PSQI)and the Epworth Sleepiness Scale were used to assess patient sleep quality.Logistic regression was used to explore the potential risk factors.RESULTS The study population(n=139)had an average age of 43.40±14.56 years,and 67.6%were men(n=94).Disturbed sleep quality was observed in 86 patients(61.9%)during hospitalization and remained in 46 patients(33.1%)at 6 mo after surgery.However,both PSQI and Epworth Sleepiness Scale scores showed significant improvements at 6 mo(P<0.001 and P=0.001,respectively).Multivariable logistic regression analysis showed that the potential risk factors were age(odds ratio=1.125,95%confidence interval:1.068-1.186)and PSQI assessed during hospitalization(odds ratio=1.759,95%confidence interval:1.436-2.155).The same analysis in patients with PSQI≥8 during hospitalization suggested that not using sleep medication(odds ratio=15.893,95%confidence interval:2.385-105.889)may be another risk factor.CONCLUSION The incidence of disturbed sleep after infective endocarditis surgery is high.However,the situation improves significantly over time.Age and early postoperative high PSQI score are risk factors for disturbed sleep quality at 6 mo after surgery.

文摘As the major source of energy for colonic mucosal cells and as an important regulator of gene expression,inflammation,differentiation,and apoptosis in host cells,microbiota-derived butyrate can enhance the intestinal mucosal immune barrier,modulate systemic immune response,and prevent infections.Maintaining a certain level of butyrate production in the gut can help balance intestinal microbiota,regulate host immune response,and promote the development and maintenance of the intestinal mucosal barrier.Butyrate-producing bacteria act as probiotics and play important roles in a variety of normal biological functions.Bacteriotherapeutic supplementation by using fecal microbiota transplantation to restore butyrate-producing commensal bacteria in the gut has been very successful in the treatment of recurrent and refractory Clostridium difficile(C.difficile)infection or C.difficile-negative nosocomial diarrhea.Administration of probiotics that include butyrate-producing bacteria may have a role in the treatment of inflammatory bowel diseases and in the prevention of necrotizing enterocolitis and late-onset sepsis in premature infants.Furthermore,modulating gut microbiota with dietary approaches may improve intestinal dysbiosis commonly seen in patients with obesity-associated metabolic disorders.Supplementation with a butyrate-producing bacterial stain might be used to increase energy expenditure,improve insulin sensitivity,and to help control obesity and metabolic syndrome.

文摘BACKGROUND Butylphthalide(NBP)and edaravone(EDV)injection are common acute ischemic stroke medications in China,but there is a lack of large real-world safety studies on them.This study aimed to determine the incidence of adverse events,detect relevant safety signals,and assess the risk factors associated with these medications in real-world populations.METHODS In this study,data of acute ischemic stroke patients were extracted from the electronic medical record database of six tertiary hospitals between January 2019 and August 2021.Baseline confounders were eliminated using propensity score matching.The drugs’safety was estimated by comparing the results of 24 laboratory tests standards on liver function,kidney function,lipid level,and coagulation function.The drugs’relative risk was estimated by logistic regression.A third group with patients who did not receive NBP or EDV was constructed as a reference.Prescription sequence symmetry analysis was used to evaluate the associations between adverse events and NBP and EDV,respectively.RESULTS 81,292 patients were included in this study.After propensity score matching,the NBP,EDV,and third groups with 727patients in each group.Among the 15 test items,the incidence of adverse events was lower in the NBP group than in the EDV group,and the differences were statistically significant.The multivariate logistic regression equation revealed that NBP injection was not a promoting factor for abnormal laboratory test results,whereas EDV had statistically significant effects on aspartate transaminase,low-density lipoprotein cholesterol and total cholesterol.Prescription sequence symmetry analysis showed that NBP had a weak correlation with abnormal platelet count.EDV had a positive signal associated with abnormal results in gamma-glutamyl transferase,alanine aminotransferase,aspartate aminotransferase,prothrombin time,and platelet count.CONCLUSIONS In a large real-world population,NBP has a lower incidence of adverse events and a better safety profile than EDV or other usual medications.

文摘This study was designed to investigate the protective effects of Astaxanthin(AST)in rats with diabetes mellitus(DM)induced by streptozotocin.SD rats were divided into control group(n=5,only received normal saline),DM group(n=8)and AST+DM group(n=8;AST:50 mg/kg/day).DM rats were induced by intraperitoneal injection of streptozocin(STZ,65 mg/kg).Blood glucose level and body weight were determined at weeks 0,2,4,6 and 8,respectively.At week 8,kidney function was determined,together with expression of P53 and dynamin-related protein-1(Drp1)by Western blot analysis and immunofluorescence.AST led to increase of body weight in rats with DM.AST+DM group showed a significant decrease in blood glucose level at week 4 compared with DM group(P<0.05).AST improved renal function and significantly reduced expression of P53 and Drp1 in DM rats.In addition,AST can effectively reduce the blood glucose in DM rats,and delayed the pathogenesis of diabetic nephropathy.Such delay mediated by AST may be associated with the downregulation of Drp1 and P53.
