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

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

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

The distention of the colon without mechanical or anatomical obstruction, Acute Colonic Pseudo-obstruction (ACPO), is a common condition occurring in the critically ill. ACPO in the setting of an acute pulmonary embolism and embolic stroke is a rarity. A 76-year-old female with shortness of breath, left hemiparesis and right-sided paresthesias presented with acute pulmonary embolism and acute infarcts of the left caudate nucleus, thalamus and occipital lobe. Her hospitalization was complicated with persistent distention of the large bowel without dilation of the small bowel. Empiric antibiotics were initiated without improvement and laboratory studies including Clostridium difficile were negative. She underwent nasogastric decompression and two decompressive colonoscopies with a resolution of her symptoms. This case illustrates an example of acute abdominal distension, without underlying etiology, in the setting of acute embolism of the pulmonary and cerebral vasculature. Early identification and action with decompressive colonoscopy were key to preventing further bowel damage or rupture. 展开更多

Hypertension is a primary risk factor for the progression of cognitive impairment caused by cerebral small vessel disease,the most common cerebrovascular disease.Howeve r,the causal relationship between hypertension and cerebral small vessel disease remains unclear.Hypertension has substantial negative impacts on brain health and is recognized as a risk factor for cerebrovascular disease.Chronic hypertension and lifestyle factors are associated with risks for stro ke and dementia,and cerebral small vessel disease can cause dementia and stroke.Hypertension is the main driver of cerebral small vessel disease,which changes the structure and function of cerebral vessels via various mechanisms and leads to lacunar infarction,leukoaraiosis,white matter lesions,and intracerebral hemorrhage,ultimately res ulting in cognitive decline and demonstrating that the brain is the to rget organ of hypertension.This review updates our understanding of the pathogenesis of hypertensioninduced cerebral small vessel disease and the res ulting changes in brain structure and function and declines in cognitive ability.We also discuss drugs to treat cerebral small vessel disease and cognitive impairment. 展开更多

OBJECTIVES Stress-related glycemic indicators,including admission blood glucose(ABG),stress-hyperglycemia ratio(SHR),and glycemic gap(GG),have been associated with worse outcomes after acute myocardial infarction(AMI).However,data regarding their prognostic value in the oldest old with AMI are unavailable.Therefore,this study aimed to investigate the association of stress-related glycemic indicators with short-and long-term cardiovascular mortality(CVM)in the oldest old(≥80 years)with AMI.METHODS In this prospective study,a total of 933 consecutive old patients with AMI admitted to FuWai hospital(Beijing,China)were enrolled.On admission,ABG,SHR,and GG were assessed and all participants were classified according to their quartiles.Kaplan-Meier,restricted cubic splines(RCS),and multivariate Cox regression analyses were performed to evaluate the association between these glycemic indicators and CVM within 30 days and long-term follow-up.RESULTS During an average of 1954 patient-years of follow-up,a total of 250 cardiovascular deaths were recorded.Kaplan-Meier analyses showed the lowest CVM in quartile 1 of ABG and in quartile 2 of SHR and GG.After adjusting for potential covariates,patients in quartile 4 of ABG,SHR,and GG had a respective 1.67-fold(95%CI:1.03-2.69;P=0.036),1.80-fold(95%CI:1.16-2.79;P=0.009),and 1.78-fold(95%CI:1.14-2.79;P=0.011)higher risk of long-term CVM risk compared to those in the reference groups(quartile 1 of ABG and quartile 2 of SHR and GG).Furthermore,RCS suggested a J-shaped relationship of ABG and a Ushaped association of SHR and GG with long-term CVM.Additionally,we observed similar associations of these acute glycemic parameters with 30-day CVM.CONCLUSIONS Our data first indicated that SHR and GG consistently had a U-shaped association with both 30-day and longterm CVM among the oldest old with AMI,suggesting that they may be useful for risk stratification in this special population. 展开更多

Myocardial damage resulting from acute myocardial infarction often leads to progressive heart failure and sudden death,highlighting the urgent clinical need for effective therapies.Recently,tanshinoneⅡA has been identified as a promising therapeutic agent for myocardial infarction.However,efficient delivery remains a major issue that limits clinical translation.To address this problem,an injectable thermosensitive poly(lactic acid-co-glycolic acid)-block-poly(ethylene glycol)-block-poly(lactic acid-co-glycolic acid)gel(PLGA-PEG-PLGA)system encapsulating tanshinoneⅡA-loaded reactive oxygen species-sensitive microspheres(Gel-MS/tanshinoneⅡA)has been designed and synthesized in this study.The thermosensitive hydrogel exhibits good mechanical properties after reaching body temperature.Microspheres initially immobilized by the gel exhibit excellent reactive oxygen species-triggered release properties in a high-reactive oxygen species environment after myocardial infarction onset.As a result,encapsulated tanshinoneⅡA is effectively released into the infarcted myocardium,where it exerts local anti-pyroptotic and anti-inflammatory effects.Importantly,the combined advantages of this technique contribute to the mitigation of left ventricular remodeling and the restoration of cardiac function following tanshinoneⅡA.Therefore,this novel,precision-guided intra-tissue therapeutic system allows for customized local release of tanshinoneⅡA,presenting a promising alternative treatment strategy aimed at inducing beneficial ventricular remodeling in the post-infarct heart. 展开更多

BACKGROUND The aging of the population has become increasingly obvious in recent years,and the incidence of cerebral infarction has shown an increasing trend annually,with high death and disability rates.AIM To analyze the effects of infarct location and volume on cognitive dysfunction in elderly patients with acute insular cerebral infarction.METHODS Between January 2020 and December 2023,we treated 98 cases of elderly acute insula,patients with cerebral infarction in the cerebral infarction acute phase(3-4 weeks)and for the course of 6 months in Montreal Cognitive Assessment Scale(MoCA)for screening of cognition.Notably,58 and 40 patients were placed in the cognitive impairment group and without-cognitive impairment group,respec-tively.In patients with cerebral infarction,magnetic resonance imaging was used to screen and clearly analyze the MoCA scores of two groups of patients with different infarctions,the relationship between the parts of the infarction volume,and analysis of acute insula cognitive disorder in elderly patients with cerebral RESULTS The number of patients with cognitive impairment in the basal ganglia and thalamus was significantly higher than that without cognitive impairment(P<0.05).The total infarct volume in the cognitive impairment group was higher than that in the non-cognitive impairment group,and the difference was statistically significant(P<0.05).The infarct volumes at different sites in the cognitive impairment group was higher than in the non-cognitive impairment group(P<0.05).In the cognitive impairment group,the infarct volumes in the basal ganglia,thalamus,and mixed lesions were negatively correlated with the total MoCA score,with correlation coefficients of-0.67,-0.73,and-0.77,respectively.CONCLUSION In elderly patients with acute insular infarction,infarction in the basal ganglia,thalamus,and mixed lesions were more likely to lead to cognitive dysfunction than in other areas,and patients with large infarct volumes were more likely to develop cognitive dysfunction.The infarct volume in the basal ganglia,thalamus,and mixed lesions was significantly negatively correlated with the MoCA score. 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

Background:Myocardial infarction(MI)is an acute condition in which the heart mus-cle dies due to the lack of blood supply.Previous research has suggested that au-tophagy and angiogenesis play vital roles in the prevention of heart failure after MI,and miR-106a is considered to be an important regulatory factor in MI.But the specific mechanism remains unknown.In this study,using cultured venous endothelial cells and a rat model of MI,we aimed to identify the potential target genes of miR-106a and discover the mechanisms of inhibiting autophagy and angiogenesis.Methods:We first explored the biological functions of miR-106a on autophagy and angiogenesis on endothelial cells.Then we identified ATG7,which was the down-stream target gene of miR-106a.The expression of miR-106a and ATG7 was investi-gated in the rat model of MI.Results:We found that miR-106a inhibits the proliferation,cell cycle,autophagy and angiogenesis,but promoted the apoptosis of vein endothelial cells.Moreover,ATG7 was identified as the target of miR-106a,and ATG7 rescued the inhibition of autophagy and angiogenesis by miR-106a.The expression of miR-106a in the rat model of MI was decreased but the expression of ATG7 was increased in the infarction areas.Conclusion:Our results indicate that miR-106a may inhibit autophagy and angiogenesis by targeting ATG7.This mechanism may be a potential therapeutic treatment for MI. 展开更多

BACKGROUND Myocardial infarction(MI)is a critical cardiovascular event with multifaceted etiology,involving several genetic and environmental factors.It is essential to understand the function of plasma metabolites in the development of MI and unravel its complex pathogenesis.METHODS This study employed a bidirectional Mendelian randomization(MR)approach to investigate the causal relationships between plasma metabolites and MI risk.We used genetic instruments as proxies for plasma metabolites and MI and conducted MR analyses in both directions to assess the impact of metabolites on MI risk and vice versa.In addition,the large-scale genome-wide association studies datasets was used to identify genetic variants associated with plasma metabolite(1400 metabolites)and MI(20,917 individuals with MI and 440,906 individuals without MI)susceptibility.Inverse variance weighted was the primary method for estimating causal effects.MR estimates are expressed as beta coefficients or odds ratio(OR)with 95%CI.RESULTS We identified 14 plasma metabolites associated with the occurrence of MI(P<0.05),among which 8 plasma metabolites[propionylglycine levels(OR=0.922,95%CI:0.881–0.965,P<0.001),gamma-glutamylglycine levels(OR=0.903,95%CI:0.861–0.948,P<0.001),hexadecanedioate(C16-DC)levels(OR=0.941,95%CI:0.911–0.973,P<0.001),pentose acid levels(OR=0.923,95%CI:0.877–0.972,P=0.002),X-24546 levels(OR=0.936,95%CI:0.902–0.971,P<0.001),glycine levels(OR=0.936,95%CI:0.909–0.964,P<0.001),glycine to serine ratio(OR=0.930,95%CI:0.888–0.974,P=0.002),and mannose to trans-4-hydroxyproline ratio(OR=0.912,95%CI:0.869–0.958,P<0.001)]were correlated with a decreased risk of MI,whereas the remaining 6 plasma metabolites[1-palmitoyl-2-arachidonoyl-GPE(16:0/20:4)levels(OR=1.051,95%CI:1.018–1.084,P=0.002),behenoyl dihydrosphingomyelin(d18:0/22:0)levels(OR=1.076,95%CI:1.027–1.128,P=0.002),1-stearoyl-2-docosahexaenoyl-GPE(18:0/22:6)levels(OR=1.067,95%CI:1.027–1.109,P=0.001),alpha-ketobutyrate levels(OR=1.108,95%CI:1.041–1.180,P=0.001),5-acetylamino-6-formylamino-3-methyluracil levels(OR=1.047,95%CI:1.019–1.076,P<0.001),and N-acetylputrescine to(N(1)+N(8))-acetylspermidine ratio(OR=1.045,95%CI:1.018–1.073,P<0.001)]were associated with an increased risk of MI.Furthermore,we also observed that the mentioned relationships were unaffected by horizontal pleiotropy(P>0.05).On the contrary,MI did not lead to significant alterations in the levels of the aforementioned 14 plasma metabolites(P>0.05 for each comparison).CONCLUSIONS Our bidirectional MR study identified 14 plasma metabolites associated with the occurrence of MI,among which 13 plasma metabolites have not been reported previously.These findings provide valuable insights for the early diagnosis of MI and potential therapeutic targets. 展开更多

OBJECTIVES To evaluate the predictive value of fasting plasma glucose(FPG)for in-hospital mortality in patients with acute myocardial infarction(AMI)with different glucose metabolism status.METHODS We selected 5,308 participants with AMI from the prospective,nationwide,multicenter CAMI registry,of which 2,081 were diabetic and 3,227 were nondiabetic.Patients were divided into high FPG and low FPG groups according to the optim-al cutoff values of FPG to predict in-hospital mortality for diabetic and nondiabetic cohorts,respectively.The primary endpoint was in-hospital mortality.RESULTS Overall,94 diabetic patients(4.5%)and 131 nondiabetic patients(4.1%)died during hospitalization,and the optimal FPG thresholds for predicting in-hospital death of the two cohorts were 13.2 mmol/L and 6.4 mmol/L,respectively.Compared with individuals who had low FPG,those with high FPG were significantly associated with higher in-hospital mortality in diabet-ic cohort(10.1%vs.2.8%;odds ratio[OR]=3.862,95%confidence interval[CI]:2.542-5.869)and nondiabetic cohort(7.4%vs.1.7%;HR=4.542,95%CI:3.041-6.782).After adjusting the potential confounders,this significant association was not changed.Further-more,FPG as a continuous variable was positively associated with in-hospital mortality in single-variable and multivariable models regardless of diabetic status.Adding FPG to the original model showed a significant improvement in C-statistic and net reclassification in diabetic and nondiabetic cohorts.CONCLUSIONS This large-scale registry indicated that there is a strong positive association between FPG and in-hospital mor-tality in AMI patients with and without diabetes.FPG might be useful to stratify patients with AMI. 展开更多

Thrombophilia denotes a condition,whether acquired or hereditary,characterized by increased susceptibility to hypercoagulation.[1]This condition was first described in 1965,coinciding with the discovery of an inherited predisposition to venous thromboembolism(VTE)in patients deficient in antithrombin III.[2]While arterial and venous thromboses are common in hospitalized patients,acute myocardial infarction(AMI)and pulmonary embolism(PE)stand out as lifethreateningconditions.However,theoccurrenceof AMI complicated by PE is exceedingly rare,especially when considering cases where paradoxical embolism originating from a patent foramen ovale is absent.This report presents a case of AMI complicated with PE.A comprehensive understanding of the pathophysiology of this rare yet critical condition is important for ensuring prompt diagnosis and treatment. 展开更多
