AIM To investigate the long-term prognosis in peptic ulcer patients continuing taking antithrombotics after ulcer bleeding, and to determine the risk factors that influence the prognosis. METHODS All clinical data of peptic ulcer patients treated from January 1, 2009 to January 1, 2014 were retrospectively collected and analyzed. Patients were divided into either a continuing group to continue taking antithrombotic drugs after ulcer bleeding or a discontinuing group to discontinue antithrombotic drugs. The primary outcome of follow-up in peptic ulcer bleeding patients was recurrent bleeding, and secondary outcome was death or acute cardiovascular disease occurrence. The final date of follow-up was December 31, 2014. Basic demographic data, complications, and disease classifications were analyzed and compared by t- or χ2-test. The number of patients that achieved various outcomes was counted and analyzed statistically. A survival curve was drawn using the Kaplan-Meier method, and the differencewas compared using the log-rank test. COX regression multivariate analysis was applied to analyze risk factors for the prognosis of peptic ulcer patients. RESULTS A total of 167 patients were enrolled into this study. As for the baseline information, differences in age, smoking, alcohol abuse, and acute cardiovascular diseases were statistically significant between the continuing and discontinuing groups(70.8 ± 11.4 vs 62.4 ± 12.0, P < 0.001; 8(8.2%) vs 15(21.7%), P < 0.05; 65(66.3%) vs 13(18.8%), P < 0.001). At the end of the study, 18 patients had recurrent bleeding and three patients died or had acute cardiovascular disease in the continuing group, while four patients had recurrent bleeding and 15 patients died or had acute cardiovascular disease in the discontinuing group. The differences in these results were statistically significant(P = 0.022, P = 0.000). The Kaplan-Meier survival curve indicated that the incidence of recurrent bleeding was higher in patients in the continuing group, and the risk of death and developing acute cardiovascular disease was higher in patients in the discontinuing group(log-rank test, P = 0.000 for both). Furthermore, COX regression multivariate analysis revealed that the hazard ratio(HR) for recurrent bleeding was 2.986(95%CI: 067-8.356, P = 0.015) in the continuing group, while HR for death or acute cardiovascular disease was 5.216(95%CI: 1.035-26.278, P = 0.028).CONCLUSION After the occurrence of peptic ulcer bleeding, continuing antithrombotics increases the risk of recurrent bleeding events, while discontinuing antithrombotics would increase the risk of death and developing cardiovascular disease. This suggests that clinicians should comprehensively consider the use of antithrombotics after peptic ulcer bleeding. 展开更多

BACKGROUND Traumatic injuries,such as falling,car accidents,and crushing mostly cause spinal fractures in young and middle-aged people,and>50%of them are thoracolumbar fractures.This kind of fracture is easily combined with serious injuries to peripheral nerves and soft tissues,which causes paralysis of the lower limbs if there is no timely rehabilitation treatment.Young patients with thoracolumbar fractures find it difficult to recover after the operation,and they are prone to depression,low self-esteem,and other negative emotions.AIM To investigate the association between anxiety,depression,and social stress in young patients with thoracolumbar spine fractures and the effect on rehabilitation outcomes.METHODS This study retrospectively analyzed 100 patients admitted to the orthopedic department of Honghui Hospital,Xi’an Jiaotong University who underwent thoracolumbar spine fracture surgery from January 2022 to June 2023.The general data of the patients were assessed with the Hamilton anxiety scale(HAMA),Hamilton depression scale(HAMD),life events scale,and social support rating scale(SSRS)to identify the correlation between anxiety,depression scores,and social stress and social support.The Japanese Orthopedic Association(JOA)was utilized to evaluate the rehabilitation outcomes of the patients and to analyze the effects of anxiety and depression scores on rehabilitation.RESULTS According to the scores of HAMD and HAMA in all patients,the prevalence of depression in patients was 39%(39/100),and the prevalence of anxiety was 49%(49/100).Patients were categorized into non-depression(n=61)and depression(n=39),non-anxiety(n=51),and anxiety(n=49)groups.Statistically significant differences in gender,occupation,Pittsburgh Sleep Quality Index(PSQI)score,and monthly family income were observed between the non-depression and depression groups(P<0.05).A significant difference in occupation and PSQI score was found between the non-anxiety and anxiety groups.Both depression(r=0.207,P=0.038)and anxiety scores(r=0.473,P<0.001)were significantly and positively correlated with negative life events.The difference in negative life event scores as well as SSRS total and item scores was statist-ically significant between patients in the non-depression and depression groups(P<0.05).The difference between the non-anxiety and anxiety groups was statistically significant(P<0.05)in the negative life event scores as well as the total SSRS scores.Additionally,JOA scores were significantly lower in both anxious and depressed patients.CONCLUSION Young patients with thoracolumbar fractures are prone to anxiety and depression.Patients’anxiety and depression are closely associated with social pressure,which reduces the life pressure of young patients with thoracolumbar fractures,enhances social support,and improves the psychology of anxiety and depression.,which affects patients’recovery. 展开更多

Epidemiological studies have indicated that branched-chain amino acids(BCAAs)increased and gut microbiota disordered in type 2 diabetes mellitus(T2DM).This study aimed to investigate the mechanism of Lactiplantibacillus plantarum strain 84-3(Lp84-3)combined with Staphylococcus aureus bacteriophage on ameliorating T2DM.Here we perform a case-control study and identify that Staphylococcus_phage was inversely correlated with fasting blood glucose(FBG).It revealed that Lp84-3 could inhibit the growth of S.aureus,and Lp84-3 contains BCAAs degradation enzymes in its genome.Furthermore,Lp84-3 alone or combined with S.aureus bacteriophage interventions can improve blood glucose,insulin resistance,triglycerides,interleukin-1β,tumor necrosis factor-α(TNF-α),BCAAs,and acetyllactate synthase(ALS)in db/db mice.Lp84-3 and S.aureus bacteriophage decreased S.aureus,Malacoplasma iowae,and Oscillibacter sp.,and increased some beneficial such as L.plantarum and Muribaculaceae bacterium.Transcriptomic analyses revealed that Lp84-3 and S.aureus bacteriophage activated the PI3K/AKT/GLUT4 signaling pathway and upregulated key genes of Il22,Hgf,Col6a1,Gh,Itga10,Fgf23,and Prl involved in glucose metabolism in hypothalamus.Collectively,Lp84-3 and S.aureus bacteriophage alleviate T2DM by modulating gut microbiota and enhancing glucose metabolism in hypothalamus,supporting its potential use as a promising functional compound microecological agent for alleviating T2DM. 展开更多

Autophagy directly regulates the amyloid beta-peptide(Aβ)clearance,and its dysfunction occurs in the early pathogenesis of Alzheimer's disease(AD).We previously reported that docosahexaenoic acid-acylated astaxanthin monoester(AST-DHA)showed neuroprotection against AD pathology.However,its in-depth mechanism and autophagic responses in AD brains are poorly understood.Herein,SH-SY5Y cells overexpressing the Swedish mutation(K595N/M596L)of APP gene were established to preliminarily evaluate the actions of AST-DHA on reducing Aβ_(1-42)levels and regulating autophagy.In microglial BV2 cells,AST-DHA and free astaxanthin(F-AST)recovered p62 and LC3Ⅱ/Ⅰlevels,and restored autophagy flux by rescuing the late phase of microglial autophagy.Notably,autophagic inhibitor bafilomycin A1 blunted the abilities of AST-DHA to reduce Aβ_(1-42)and fibral Aβ,suggesting that AST-DHA probably promoted Aβclearance in a microglial autophagy-dependent manner.Further studies in APP/PS1 mice verified that dietary AST-DHA and F-AST promoted Aβphagocytosis via microglial autophagy.Significant decreases of Iba1 and p62 were observed around Aβplaque in the hippocampus and cortex using triple fluorescence staining.Furthermore,AST-DHA exhibited superior performance over F-AST in restoring autophagic dysfunction,ameliorating Aβburden and cognitive deficit.Our findings suggest a possible mechanism of AST-DHA in improving AD by which it restores microglial autophagy to facilitate cerebral Aβclearance.It supports the future application of AST-DHA as an autophagic regulator in maintaining brain function. 展开更多

Biological load-bearing materials,like the nacre in shells,have a unique staggered structure that supports their superior mechanical properties.Engineers have been encouraged to imitate it to create load-bearing bio-inspired materials which have excellent properties not present in conventional composites.To create such materials with desirable mechanical properties,the optimum structural parameters combination must be selected.Moreover,the optimal design of bio-inspired composites needs to take into account the trade-offs between various mechanical properties.In this paper,multi-objective optimization models were developed using structural parameters as design variables and mechanical properties as optimization objectives,including stiffness,strength,toughness,and dynamic damping.Using the NSGA-II optimization algorithm,a set of optimal solutions were solved.Additionally,three different structures in natural nacre were introduced in order to utilize the better structure when design bio-inspired materials.The range of optimal solutions that obtained using results from previous research were examined and explained why this collection of optimal solution ranges is better.Also,optimal solutions were compared with the structural features and mechanical properties of real nacre and artificial biomimetic composites to validate our models.Finally,the optimum design strategies can be obtained for nacre-like composites.Our research methodically proposes an optimization method for achieving load-bearing bio-inspired materials with excellent properties and creates a set of optimal solutions from which designers can select the one that best suits their preferences,allowing the fabricated materials to demonstrate preferred performance. 展开更多

AIM: To investigate the changes of lymphocyte subpopulations, especially CD4^+CD25^ T regulatory cells in Smad3^-/- mice. METHODS: Hematological changes and changes of lymphocyte subpopulations were detected in Smad3"/- mice using cell counter and flow cytometry, respectively, and compared to their littermate controls. RESULTS: The numbers of neutrophils and lymphocytes in peripheral blood were significantly increased in Smad3^-/- mice compared to littermate controls. CD19^+ expressing cells in blood and spleen, and CD8^+ T cells in thymus were all markedly decreased in Smad3^-/- mice. More important, Smad3^-/- mice had an increased population of CD4^+CD25^+ T cells in peripheral lymphoid tissues, including thymus, spleen, and lymph nodes. CONCLUSION: These observations suggest that the changes of lymphocyte subpopulations might play a role in susceptibility to inflammation of Smad3^-/- mice. 展开更多

Theranostic visualization of dextran at the nanoscale is beneficial for understanding the bioregulatory mechanisms of this molecule. In this study, we applied structured illumination microscopy(SIM) to capture the distribution of Cy5-Dextran at different incubation periods in living cells. The results showed that Cy5-Dextran could be absorbed by He La cells. In addition, we clarified that Cy5-Dextran exhibited differential organelle distribution(lysosomal or mitochondrial) in a time-dependent manner. Moreover,lysosomal Cy5-Dextran localization was found to be independent of the autophagy process, while Cy5-Dextran localized to the mitochondria triggered a pro-apoptotic event, upregulating the levels of reactive oxygen species(ROS) to accelerate mitochondrial fragmentation. This work uses a visualized strategy to reveal the anti-tumor bioactivity of dextran, which was achieved by regulating apoptosis and autophagy. 展开更多

A series of mono-and binuclear Co(Ⅱ) complexes (Col-Co7) supported by quinoline-2-imidate ligands were synthesized and thoroughly characterized. Measured by single crystal X-ray crystallography, complexes Col and Co3 adopted distorted tetrahedral structures around the cobalt center. Upon activation by ethylaluminium sesquichloride (EASC), these cobalt complexes exhibited high catalytic activity and cis-l,4-selectivity towards 1,3-butadiene polymerization. The effects of ligand environment, polymerization temperature, and cocatalyst types on the polymerization were investigated in detail. Interestingly, the binuclear Co(Ⅱ) complexes exhibited high thermal stability, and the polymer yields were up to 97.2% even at a high temperature of 70 ℃. 展开更多

The motivation for this study is that the quality of deep fakes is constantly improving,which leads to the need to develop new methods for their detection.The proposed Customized Convolutional Neural Network method involves extracting structured data from video frames using facial landmark detection,which is then used as input to the CNN.The customized Convolutional Neural Network method is the date augmented-based CNN model to generate‘fake data’or‘fake images’.This study was carried out using Python and its libraries.We used 242 films from the dataset gathered by the Deep Fake Detection Challenge,of which 199 were made up and the remaining 53 were real.Ten seconds were allotted for each video.There were 318 videos used in all,199 of which were fake and 119 of which were real.Our proposedmethod achieved a testing accuracy of 91.47%,loss of 0.342,and AUC score of 0.92,outperforming two alternative approaches,CNN and MLP-CNN.Furthermore,our method succeeded in greater accuracy than contemporary models such as XceptionNet,Meso-4,EfficientNet-BO,MesoInception-4,VGG-16,and DST-Net.The novelty of this investigation is the development of a new Convolutional Neural Network(CNN)learning model that can accurately detect deep fake face photos. 展开更多
