Clinical characteristics of acute non-varicose upper gastrointestinal bleeding and the effect of endoscopic hemostasis

BACKGROUND Acute non-variceal upper gastrointestinal bleeding(ANVUGIB)constitutes a prevalent emergency within Gastroenterology,encompassing 80%-90%of all gastrointestinal hemorrhage incidents.This condition is distinguished by its abrupt onset,swift progression,and notably elevated mortality rate.AIM To gather clinical data from patients with ANVUGIB at our hospital in order to elucidate the clinical characteristics specific to our institution and analyze the therapeutic effectiveness of endoscopic hemostasis.METHODS We retrospectively retrieved the records of 532 patients diagnosed with ANVUGIB by endoscopy at our hospital between March 2021 and March 2023,utilizing our medical record system.Data pertaining to general patient information,etiological factors,disease outcomes,and other relevant variables were meticulously collected and analyzed.RESULTS Among the 532 patients diagnosed with ANVUGIB,the male-to-female ratio was 2.91:1,with a higher prevalence among males.Notably,43.6%of patients presented with black stool as their primary complaint,while 27.4%had hematemesis as their initial symptom.Upon admission,17%of patients exhibited both hematemesis and black stool,while most ANVUGIB patients primarily complained of overt gastrointestinal bleeding.Urgent routine blood examinations at admission revealed that 75.8%of patients had anemia,with 63.4%experiencing moderate to severe anemia,and 1.5%having extremely severe anemia(hemoglobin<30 g/L).With regard to etiology,53.2%of patients experienced bleeding without a definitive trigger,24.2%had a history of using gastric mucosa-irritating medications,24.2%developed bleeding after alcohol consumption,2.8%attributed it to improper diet,1.7%to emotional excitement,and 2.3%to fatigue preceding the bleeding episode.Drug-induced ANVUGIB was more prevalent in the elderly than middle-aged and young individuals,while bleeding due to alcohol consumption showed the opposite trend.Additionally,diet-related bleeding was more common among the young age group compared to the middle-aged group.Gastrointestinal endoscopy identified peptic ulcers as the most frequent cause of ANVUGIB(73.3%),followed by gastrointestinal malignancies(10.9%),acute gastric mucous lesions(9.8%),and androgenic upper gastrointestinal bleeding(1.5%)among inpatients with ANVUGIB.Of the 532 patients with gastrointestinal bleeding,68 underwent endoscopic hemostasis,resulting in an endoscopic treatment rate of 12.8%,with a high immediate hemostasis success rate of 94.1%.

Enterogenic Stenotrophomonas maltophilia migrates to the mammary gland to induce mastitis by activating the calcium-ROS-AMPK-mTOR-autophagy pathway

Background Mastitis is an inflammatory disease of the mammary gland that has serious economic impacts on the dairy industry and endangers food safety.Our previous study found that the body has a gut/rumen-mammary gland axis and that disturbance of the gut/rumen microbiota could result in‘gastroenterogenic mastitis'.However,the mechanism has not been fully clarified.Recently,we found that long-term feeding of a high-concentrate diet induced mastitis in dairy cows,and the abundance of Stenotrophomonas maltophilia(S.maltophilia)was significantly increased in both the rumen and milk microbiota.Accordingly,we hypothesized that‘gastroenterogenic mastitis'can be induced by the migration of endogenous gut bacteria to the mammary gland.Therefore,this study investigated the mechanism by which enterogenic S.maltophilia induces mastitis.Results First,S.maltophilia was labelled with superfolder GFP and administered to mice via gavage.The results showed that treatment with S.maltophilia promoted the occurrence of mastitis and increased the permeability of the blood-milk barrier,leading to intestinal inflammation and intestinal leakage.Furthermore,tracking of ingested S.maltophilia revealed that S.maltophilia could migrate from the gut to the mammary gland and induce mastitis.Subsequently,mammary gland transcriptome analysis showed that the calcium and AMPK signalling pathways were significantly upregulated in mice treated with S.maltophilia.Then,using mouse mammary epithelial cells(MMECs),we verified that S.maltophilia induces mastitis through activation of the calcium-ROS-AMPK-mTOR-autophagy pathway.Conclusions In conclusion,the results showed that enterogenic S.maltophilia could migrate from the gut to the mammary gland via the gut-mammary axis and activate the calcium-ROS-AMPK-mTOR-autophagy pathway to induce mastitis.Targeting the gut-mammary gland axis may also be an effective method to treat mastitis.

Understanding the molecular crossroads in acute liver failure:A pathway to new therapies

In this editorial we comment on the article published in a recent issue of the World Journal of Gastroenterology.Acute liver failure(ALF)is a critical condition characterized by rapid hepatocellular injury and organ dysfunction,and it often necessitates liver transplant to ensure patient survival.Recent research has eluci-dated the involvement of distinct cell death pathways,namely ferroptosis and pyroptosis,in the pathogenesis of ALF.Ferroptosis is driven by iron-dependent lipid peroxidation,whereas pyroptosis is an inflammatory form of cell death;both pathways contribute to hepatocyte death and exacerbate tissue damage.This comprehensive review explores the interplay between ferroptosis and pyroptosis in ALF,highlighting the role of key regulators such as silent information regulator sirtuin 1.Insights from clinical and preclinical studies provide valuable perspectives on the dysregulation of cell death pathways in ALF and the therapeutic potential of targeting these pathways.Collaboration across multiple disciplines is essential for translating the experimental insights into effective treatments for this life-threatening condition.

To explore the mechanism of Yigong San anti-gastric cancer and immune regulation

BACKGROUND Yigong San(YGS)is a representative prescription for the treatment of digestive disorders,which has been used in clinic for more than 1000 years.However,the mechanism of its anti-gastric cancer and regulate immunity are still remains unclear.AIM To explore the mechanism of YGS anti-gastric cancer and immune regulation.METHODS Firstly,collect the active ingredients and targets of YGS,and the differentially expressed genes of gastric cancer.Secondly,constructed a protein-protein interaction network between the targets of drugs and diseases,and screened hub genes.Then the clinical relevance,mutation and repair,tumor microenvironment and drug sensitivity of the hub gene were analyzed.Finally,molecular docking was used to verify the binding ability of YGS active ingredient and hub genes.RESULTS Firstly,obtained 55 common targets of gastric cancer and YGS.The Kyoto Encyclopedia of Genes and Genomes screened the microtubule-associated protein kinase signaling axis as the key pathway and IL6,EGFR,MMP2,MMP9 and TGFB1 as the hub genes.The 5 hub genes were involved in gastric carcinogenesis,staging,typing and prognosis,and their mutations promote gastric cancer progression.Finally,molecular docking results confirmed that the components of YGS can effectively bind to therapeutic targets.CONCLUSION YGS has the effect of anti-gastric cancer and immune regulation.

Mental health status among COVID-19 patients survivors of critical illness in Saudi Arabia:A 6-month follow-up questionnaire study

BACKGROUND Psychological assessment after intensive care unit(ICU)discharge is increasingly used to assess patients'cognitive and psychological well-being.However,few studies have examined those who recovered from coronavirus disease 2019(COVID-19).There is a paucity of data from the Middle East assessing the post-ICU discharge mental health status of patients who had COVID-19.AIM To evaluate anxiety and depression among patients who had severe COVID-19.METHODS This is a prospective single-center follow-up questionnaire-based study of adults who were admitted to the ICU or under ICU consultation for>24 h for COVID-19.Eligible patients were contacted via telephone.The patient’s anxiety and depression six months after ICU discharge were assessed using the Hospital Anxiety and Depression Scale(HADS).The primary outcome was the mean HADS score.The secondary outcomes were risk factors of anxiety and/or depression.RESULTS Patients who were admitted to the ICU because of COVID-19 were screened(n=518).Of these,48 completed the questionnaires.The mean age was 56.3±17.2 years.Thirty patients(62.5%)were male.The main comorbidities were endocrine(n=24,50%)and cardiovascular(n=21,43.8%)diseases.The mean overall HADS score for anxiety and depression at 6 months post-ICU discharge was 11.4(SD±8.5).A HADS score of>7 for anxiety and depression was detected in 15 patients(30%)and 18 patients(36%),respectively.Results from the multivariable ordered logistic regression demonstrated that vasopressor use was associated with the development of anxiety and depression[odds ratio(OR)39.06,95% confidence interval:1.309-1165.8;P<0.05].CONCLUSION Six months after ICU discharge,30% of patients who had COVID-19 demonstrated a HADS score that confirmed anxiety and depression.To compare the psychological status of patients following an ICU admission(with vs without COVID-19),further studies are warranted.

Spatial transcriptomics reveals that metabolic characteristics define the tumor immunosuppression microenvironment via iCAF transformation in oral squamous cell carcinoma

Tumor progression is closely related to tumor tissue metabolism and reshaping of the microenvironment. Oral squamous cell carcinoma (OSCC), a representative hypoxic tumor, has a heterogeneous internal metabolic environment. To clarify the relationship between different metabolic regions and the tumor immune microenvironment (TME) in OSCC, Single cell (SC) and spatial transcriptomics (ST) sequencing of OSCC tissues were performed. The proportion of TME in the ST data was obtained through SPOTlight deconvolution using SC and GSE103322 data. The metabolic activity of each spot was calculated using scMetabolism,and k-means clustering was used to classify all spots into hyper-, normal-, or hypometabolic regions. CD4T cell infiltration and TGF-βexpression is higher in the hypermetabolic regions than in the others. Through CellPhoneDB and NicheNet cell-cell communication analysis, it was found that in the hypermetabolic region, fibroblasts can utilize the lactate produced by glycolysis of epithelial cells to transform into inflammatory cancer-associated fibroblasts (iCAFs), and the increased expression of HIF1A in iCAFs promotes the transcriptional expression of CXCL12. The secretion of CXCL12 recruits regulatory T cells (Tregs), leading to Treg infiltration and increased TGF-β secretion in the microenvironment and promotes the formation of a tumor immunosuppressive microenvironment. This study delineates the coordinate work axis of epithelial cells-iCAFs-Tregs in OSCC using SC, ST and TCGA bulk data, and highlights potential targets for therapy.

Cholesterol metabolism: physiological versus pathological aspects in intracerebral hemorrhage

Cholesterol is an important component of plasma membranes and participates in many basic life functions,such as the maintenance of cell membrane stability,the synthesis of steroid hormones,and myelination.Cholesterol plays a key role in the establishment and maintenance of the central nervous system.The brain contains 20%of the whole body’s cholesterol,80%of which is located within myelin.A huge number of processes(e.g.,the sterol regulatory element-binding protein pathway and liver X receptor pathway)participate in the regulation of cholesterol metabolism in the brain via mechanisms that include cholesterol biosynthesis,intracellular transport,and efflux.Certain brain injuries or diseases involving crosstalk among the processes above can affect normal cholesterol metabolism to induce detrimental consequences.Therefore,we hypothesized that cholesterol-related molecules and pathways can serve as therapeutic targets for central nervous system diseases.Intracerebral hemorrhage is the most severe hemorrhagic stroke subtype,with high mortality and morbidity.Historical cholesterol levels are associated with the risk of intracerebral hemorrhage.Moreover,secondary pathological changes after intracerebral hemorrhage are associated with cholesterol metabolism dysregulation,such as neuroinflammation,demyelination,and multiple types of programmed cell death.Intracellular cholesterol accumulation in the brain has been found after intracerebral hemorrhage.In this paper,we review normal cholesterol metabolism in the central nervous system,the mechanisms known to participate in the disturbance of cholesterol metabolism after intracerebral hemorrhage,and the links between cholesterol metabolism and cell death.We also review several possible and constructive therapeutic targets identified based on cholesterol metabolism to provide cholesterol-based perspectives and a reference for those interested in the treatment of intracerebral hemorrhage.

ON101 Cream Increases the Wound Healing Rate in Diabetic Patients with Uremia—Cases Report

Diabetic patients who underwent long-term dialysis may increase the prevalence of foot ulceration. In addition, diabetic foot ulcer (DFUs) patients with end-stage renal disease (ESRD) do not heal well, and the amputation rate is 6.5 - 10 times higher compared to the non-nephropathic diabetic population. Thus, a suitable therapeutic agent was needed. ON101 is a topical cream that promotes diabetic wound healing through a unique macrophage-regulating ability. In this case series, we included 5 diabetes patients (mean age 54.6 ± 8.7 years, 4 mal) with ESRD (mean eGFR 7.4 ± 3.35 mL/min/1.73m2) and had experienced dialysis for at least 4.5 years. These patients also have UT (University of Texas) grade 2A DFUs that have existed for at least 1.5 months (mean ulcer duration 8.3 ± 8.97 months). These subjects were applied ON101 twice daily for up to 20 weeks, and wound size was recorded during treatment. Among these subjects, three ulcers (patient No. 1, 2, and 3) completely healed within 10 weeks upon ON101 application, and one ulcer was 99% reduced at 20th weeks (patient No. 4). Only one ulcer didn’t show an obvious response that may due to poor compliance in wound care and glucose control. In summary, the overall healing rate was 60%, suggesting ON101 performed equivalence healing efficacy in dialysis patients compared with those who did not have dialysis.

Promising outcomes 5 weeks after a surgical cervical shunting procedure to unclog cerebral lymphatic systems in a patient with Alzheimer’s disease

Recently,the glymphatic system has been recognised as an important‘waste solutes transport channel’within the brain.1 Studies have shown that blockage of the glymphatic system leads to increased beta-amyloid deposits,accelerating the onset and progression of Alzheimer’s disease(AD).12 Given that cervical lymph nodes receive cerebrospinal fluid from the brain’s glymphatic system,34 we speculated that decompression of the lymphatic trunk and cervical lymphatic-venous anastomosis(LVA)could facilitate the flow of cerebrospinal fluid in the cranial glymphatic system,potentially accelerating the clearance of harmful beta-amyloid and tau proteins.We collaborated with surgeons who specialise in LVA supermicrosurgery for maxillofacial tumours and lymphoedema to develop a procedure to relieve the blockage of the glymphatic system.This surgery employs supermicrosurgery techniques to create LVA connecting the bilateral cervical,deep lymphatic vessels to the veins,resulting in lymphatic trunk decompression,which allows the lymph fluid in the high-pressure lymphatic vessels to flow into the low-pressure venous system.The goal of the minimally invasive surgery is to enhance the removal of proteins,such as beta-amyloid and tau,from the brain’s lymphatic systems to the maxillofacial lymphatic vessels,unclogging protein blockages within the brain.This extracranial procedure is safer than intracranial approaches.

Establishment and characterization of a canine chondrosarcoma cell line:Mango

In the global progress of bone tumor research,established stable and long-lasting transgenic chondrosarcoma(CSA)cell lines are rare,mainly of murine and human origin,while the establishment of canine CSA cell lines has yet to be reported.This study established a canine CSA cell line to facilitate the basic clinical study of canine CSA.Fifty fve cases of canine osteolytic disease were collected,and more than 10 bone tumor samples from dogs with typical clinical signs were used for primary cell culture.A cell line with stable passaging for more than 100 generations and mouse tumorigenic ability was successfully cultured.According to the clinical characteristics of the dog and the histopathological results of the primary tumor,CSA was diagnosed,and the CSA cell line was designated Mango.Immunohistochemical(IHC)results showed that the immunoreactivity of bone gamma-carboxyglutamate protein(BGLAP),secreted protein acidic and rich in cysteine(SPARC),alkaline phosphatase(ALPL),vimentin(VIM)and S100 were positive.However,the immunoreactivity of pan-cytokeratin(PCK),chromogranin A(CGA),and platelet endothelial cell adhesion molecule-1(CD31)was negative.Immunofuorescence(IF)results showed that the protein expressions in the Mango cell line were consistent with the IHC identifcation of the primary tumor.The Mango cell line’s doubling time was 43.92 h,and the cell formation rate exceeded 20%.There were abnormal chromosome numbers,hetero staining with toluidine blue,and certain calcifcation abilities.It could be passaged stably and continuously without changing the cell morphology and characteristics.In vivo,the cells were successfully injected into the nude mice model with a tumorigenic rate of 100%.The immunophenotype of the xenograft tumor was consistent with that of the primary tumor.Therefore,we efectively established a canine CSA cell line.As a promising cell material,this cell line can be used to construct a tumor-bearing model conducive to the subsequent basic research of canine CSA.Moreover,because of its similarity to human CSA,the animal model of CSA is also indispensable for investigating human CSA.

Electroencephalogram findings in 10 patients with post-stroke epilepsy:A retrospective study

BACKGROUND Post-stroke epilepsy is a common and easily overlooked complication of acute cerebrovascular disease.Long-term seizures can seriously affect the prognosis and quality of life of patients.Electroencephalogram(EEG)is the simplest way to diagnose epilepsy,and plays an important role in predicting seizures and guiding medication.AIM To explore the EEG characteristics of patients with post-stroke epilepsy and improve the detection rate of inter-seizure epileptiform discharges.METHODS From January 2017 to June 2020,10 patients with post-stroke epilepsy in our hospital were included.The clinical,imaging,and EEG characteristics were collected.The stroke location,seizure type,and ictal and interictal EEG manifestations of the patients with post-stroke epilepsy were then retrospectively analyzed.RESULTS In all 10 patients,epileptiform waves occurred in the side opposite to the stroke lesion during the interictal stage;these manifested as sharp wave,sharp-wave complex,or spike discharges in the anterior head lead of the side opposite to the lesion.CONCLUSION In EEG,epileptiform waves can occur in the side opposite to the stroke lesion in patients with post-stroke epilepsy.

A nanobody-based blocking enzyme-linked immunosorbent assay for detecting antibodies against pseudorabies virus glycoprotein E

Pseudorabies(PR)is an acute infectious disease of pigs caused by the PR virus(PRV)and results in great economic losses to the pig industry worldwide.PRV glycoprotein E(gE)-based enzyme-linked immunosorbent assay(ELISA)has been used to distinguish gE-deleted vaccine-immunized pigs from wild-type virus-infected pigs to eradicate PR in some countries.Nanobody has the advantages of small size and easy genetic engineering and has been a promising diagnostic reagent.However,there were few reports about developing nanobody-based ELISA for detecting anti-PRV-gE antibodies.In the present study,the recombinant PRV-gE was expressed with a bacterial system and used to immunize the Bactrian camel.Then,two nanobodies against PRV-gE were screened from the immunized camel by phage display technique.Subsequently,two nanobody-HRP fusion proteins were expressed with HEK293T cells.The PRV-gE-Nb36-HRP fusion protein was selected as the probe for developing the blocking ELISA(bELISA)to detect anti-PRV-gE antibodies.Through optimizing the conditions of bELISA,the amount of coated antigen was 200 ng per well,and dilutions of the fusion protein and tested pig sera were separately 1:320 and 1:5.The cut-off value of bELISA was 24.20%,and the sensitivity and specificity were 96.43 and 92.63%,respectively.By detecting 233 clinical pig sera with the developed bELISA and a commercial kit,the results showed that the coincidence rate of two assays was 93.99%.Additionallly,epitope mapping showed that PRV-gE-Nb36 recognized a conserved conformational epitope in different reference PRV strains.Simple,great stability and low-cost nanobody-based bELISA for detecting anti-PRV-gE antibodies were developed.The bELISA could be used for monitoring and eradicating PR.

从H1N1血凝素序列提取的沙门氏菌传递的COBRA-HA1抗原对甲型流感亚型产生广谱保护作用

A universal vaccine is in high demand to address the uncertainties of antigenic drift and the reduced effectiveness of current influenza vaccines.In this study,a strategy called computationally optimized broadly reactive antigen(COBRA)was used to generate a consensus sequence of the hemagglutinin globular head portion(HA1)of influenza virus samples collected from 1918 to 2021 to trace evolutionary changes and incorporate them into the designed constructs.Constructs carrying different HA1regions were delivered into eukaryotic cells by Salmonella-mediated bactofection using a Semliki Forest virus RNA-dependent RNApolymerase(RdRp)-based eukaryotic expression system,pJHL204.Recombinant protein expression was confirmed by Western blot and immunofluorescence assays.Mice immunized with the designed constructs produced a humoral response,with a significant increase in immunoglobulin G(IgG)levels,and a cell-mediated immune response,including a 1.5-fold increase in CD4^(+) and CD8^(+)T cells.Specifically,constructs #1 and #5 increased the production of interferon-γ(IFN-γ)producing CD4^(+)and CD8^(+)T cells,skewing the response toward the T helper type 1 cell(Th1)pathway.Additionally,interleukin-4(IL-4)-producing T cells were upregulated 4-fold.Protective efficacy was demonstrated,with up to 4-fold higher production of neutralizing antibodies and a hemagglutination inhibition titer>40 against the selected viral strains.The designed constructs conferred a broadly protective immune response,resulting in a notable reduction in viral titer and minimal inflammation in the lungs of mice challenged with the influenza A/PR8/34,A/Brisbane/59/2007,A/California/07/2009,KBPV VR-92,and NCCP 43021 strains.This discovery revolutionizes influenza vaccine design and delivery;Salmonella-mediated COBRA-HA1 is a highly effective in vivo antigen presentation strategy.This approach can effectively combat seasonal H1N1 influenza strains and potential pandemic outbreaks.

Mesenchymal stem cells: A promising therapeutic avenue for nonalcoholic fatty liver disease

Non-alcoholic fatty liver disease(NAFLD)is a pressing global health concern that is associated with metabolic syndrome and obesity.On the basis of the insights provided by Jiang et al,this editorial presents an exploration of the potential of mesenchymal stem cells(MSCs)for NAFLD treatment.MSCs have numerous desirable characteristics,including immunomodulation,anti-inflammatory pro-perties,and tissue regeneration promotion,rendering them attractive candidates for NAFLD treatment.Recent preclinical and early clinical studies have high-lighted the efficacy of MSCs in improving liver function and reducing disease severity in NAFLD models.However,MSC heterogeneity,long-term safety concerns,and unoptimized therapeutic protocols remain substantial challenges.Addressing these challenges through standardized protocols and rigorous clinical trials is essential to the safe and successful application of MSCs in NAFLD mana-gement.Continued research into MSC mechanisms and therapeutic optimization is required to improve treatments for NAFLD and related liver diseases.

Effects of Yigan Capsule on the expression of HMGB1,RAGE and NF-κB protein in rats with drug-induced liver injury

Objective:To study the effect of Yigan capsule on the expression of high mobility group protein B1(HMGB1),nuclear factor-B(NF-κB)and receptor for advanced glycation end products(RAGE)in anti-tuberculosis drug-induced liver injury(ATB-DILI),and to explore its protective effect and mechanism on ATB-DILI,so as to provide experimental basis for the clinical application of Yigan capsule.Methods:Twenty-four rats were divided into two groups.Except for the blank group(n=6),the other 18 rats were given isoniazid(INH)+rifampicin(RFP)(50 mg/kg.d)for 4 weeks.Then 18 rats were randomly divided into three groups(model group,low dose group of Yigan capsule and high dose group of Yigan capsule)according to 6 rats in each group.The blank group and the model group were given 0.9%sodium chloride solution by intragastric administration.The low dose group of Yigan capsule was 0.468 g/kg,and the high dose group of Yigan capsule was 1.872 g/kg[1].After 4 weeks,the pathological changes of liver were observed by HE staining.The contents of ALT,AST,ALP,γ-GT and TBIL were detected.The expression of HMGB1,NF-κBp65 and RAGE protein was detected by IHC.The expression levels of HMGB1,NF-κBp65,RAGE,TNF-αand IL-1βwere detected by WB.Result:HE staining showed that the structure of the liver in the model group was disordered,the liver cells showed swelling and fusion,the number of inflammatory cells increased and accompanied by punctate necrosis,while the above pathological changes in each treatment group of Yigan capsule were significantly improved.The contents of ALT,AST,ALP,γ-GT and TBIL in the model group were higher than those in the blank group(P<0.05).The contents of ALT,AST,ALP,γ-GT and TBIL in each treatment group were significantly lower than those in the model group(P<0.05).Compared with the blank group,the expression levels of TNF-αand IL-1βin the model group were increased(P<0.05),and the expression levels of HMGB1,NF-κBp65 and RAGE were increased(P<0.05).Compared with the model group,the expression levels of TNF-αand IL-1βin each treatment group of Yigan capsule decreased(P<0.05),and the expression of HMGB1,NF-κBp65 and RAGE decreased(P<0.05).Conclusion:Yigan capsule may inhibit the secretion of inflammatory factors through HMGB1/RAGE/NF-κBp65 signaling pathway,thus protecting ATB-DILI.
