    Abstract The spread of the COVID-19 virus had a huge impact on human life on the global scale. Many control measures devoted to decrease contact among people have been adopted to slow down the transmission of the disease. A series of measures have been taken in supermarkets, which include restricting the number of customers, keeping social distance, and entering with a shopping cart. In this work, we investigate with numerical simulations the effectiveness of these measures in reducing the contact among customers. Several scenarios with different control measures are designed for numerical analysis. The movements of customers in a supermarket are simulated by a microscopic model for pedestrian dynamics. Moreover, an index based on the distance between customers is defined to measure the degree of contact and therefore evaluate it quantitatively. The effect of these measures on the average contact degree of each customer is explored, and the spatial distribution of the contact among customers in the supermarket is shown in a qualitative way. Simulation results show that except shopping cart measure, the other two measures are effective in reducing contact among customers.

    Abstract Abstract Background Long non-coding RNAs (lncRNAs) play important roles in the progression of glioma. Here, we examined the potential functions of a lncRNA, LINC01003, in glioma and characterized the underlying molecular mechanisms. Methods The GEIPA2 and Chinese Glioma Genome Atlas (CCGA) databases were employed to analyze gene expression and the overall survival curve in patients with glioma. The functions of LINC01003 in glioma growth and migration were assessed by loss-of-function experiments in vitro and in vivo. RNA sequencing was used to determine the signaling pathways effected by LINC01003. Bioinformatics analysis and RNA immunoprecipitation (RIP) assays were used to explore the mechanism underlying the N6-methyladenine (m6A) modification-dependent upregulation of LINC01003 in glioma. Results LINC01003 expression was upregulated in glioma cell lines and tissues. Higher LINC01003 expression predicted shorter overall survival time in glioma patients. Functionally, LINC01003 knockdown inhibited the cell cycle and cell proliferation and migration in glioma cells. Mechanistically, RNA sequencing revealed that LINC01003 mediated the focal adhesion signaling pathway. Furthermore, LINC01003 upregulation is induced by m6A modification regulated by METTL3. Conclusion This study characterized LINC01003 as a lncRNA that contributes to tumorigenesis in glioma and demonstrated that the LINC01003-CAV1-FAK axis serves as a potential therapeutic target for glioma.

    Abstract Traditional markers, such as serum creatinine and blood urea nitrogen, frequently show delayed elevations following acute kidney injury (AKI), limiting their utility for prompt detection and timely intervention in AKI management. Shear wave elastography (SWE) exhibits potential for AKI diagnosis by measuring tissue stiffness. Our study aimed to evaluate the diagnostic performance of SWE in detecting AKI by measuring the stiffness of kidney tissue. Between July 2022 and December 2022, a total of 103 consecutive participants who met the eligibility criteria were prospectively enrolled, underwent SWE measurements, and were classified into AKI or non-AKI groups based on the 2012 Kidney Disease: Improving Global Outcomes (KDIGO) criteria. A receiver operating characteristic (ROC) curve was drawn to examine the feasibility of differentiating between AKI and non-AKI patients and assessing diagnostic performance. The effects of tissue anisotropy on SWE measurements were also examined. Our results revealed that patients in the AKI group exhibited significantly increased stiffness values in specific kidney regions compared with those in the non-AKI group. For the diagnosis of AKI, the optimal cut-off values were identified as 9.9 kPa, 2.9 kPa, and 4.4 kPa for the upper pole medulla, middle cortex, and middle medulla, respectively, in the longitudinal plane. Correspondingly, the areas under the ROC curves for these regions were 0.737 (95% confidence interval [CI]: 0.637, 0.822), 0.736 (95% CI: 0.637, 0.821), and 0.784 (95% CI: 0.688, 0.861). Additionally, we observed a significant variability in stiffness values due to tissue anisotropy, specifically in the segments of the upper pole cortex, and medulla across both longitudinal and transverse planes. SWE serves as a noninvasive approach for the quantification of tissue stiffness and shows promise as an adjunctive tool for the assessment of AKI.

    Abstract Background Myeloid-derived suppressor cell (MDSC) mobilisation is an important immune event in acute myocardial infarction (AMI). The A2B adenosine receptor (A2BAR) plays key role in regulating MDSC function, but its specific involvement in MDSC mobilisation in AMI remains unclear.Methods In AMI patients, the circulating MDSC ratio and A2BAR mRNA expression were measured. A mouse AMI model was established by left anterior descending coronary artery (LADCA) ligation. MDSCs were analysed by FACS and immunofluorescence staining (of heart tissue). A2BAR mRNA expression was assessed by qRT-PCR. Myocardial injury was detected by HE staining. Myocardial cell apoptosis was analysed by immunohistochemistry. Cardiac systolic function was evaluated by transthoracic echocardiography.Results In AMI patients, the circulating MDSC ratio was increased and positively correlated with A2BAR mRNA expression (r = 0.86, p < 0.01). In AMI model mice, the percentage of MDSCs was increased in the circulation and infarcted heart and decreased in the spleen. MRS-1754-mediated A2BAR inhibition decreased the MDSC ratio in the circulation and infarcted heart and prevented the decrease in MDSC number in the spleens of mice with AMI. A2BAR blockade inhibited myocardial cell apoptosis, alleviated myocardial inflammatory injury, and improved myocardial systolic function in the AMI mouse model. Similar results were found in mice after splenectomy. Additionally, spleen-derived MDSC injection increased the MDSC ratio in the infarcted heart, increased myocardial cell apoptosis, aggravated myocardial injury, and decreased cardiac systolic function in mice with AMI.Conclusion Blocking A2BAR alleviates myocardial damage and improves myocardial systolic function through inhibition of spleen-derived MDSC mobilisation after AMI. Key MessagesSpleen-derived MDSC mobilisation aggravates myocardial inflammatory injury within 24 h of AMI.A2BAR promotes spleen-derived MDSC mobilisation within 24 h of AMI.Blocking A2BAR improves myocardial systolic function ...

    Abstract Abstract Ulinastatin has been found to have anti-inflammatory effect for patients with sepsis. However, its clinical effects were conflicting. The study aimed to investigate the cost-effectiveness of ulinastatin and to perform mediation analysis to explore the proportion of the total effects that can be explained by inflammatory responses. This is a retrospective study involving critically ill patients with sepsis from January 2014 to July 2017. A total of 263 patients were included in the study, involving 179 patients in the ulinastatin group and 84 in the control group. Ulinastatin group showed significantly lower 28-day mortality rate than that in the control group (31% vs. 55%; p < 0.001). Both total (46330 [26000,83500] vs. 19870 [8747,41140] RMB; p < 0.01) and drug cost (18210 [9492,31920] vs. 7230 [2675,19270] RMB; p < 0.01) were significantly higher in the ulinastatin group than the control group. In multivariable model, the adjusted odds ratio for ulinastatin was 0.304 (95% CI: 0.152 to 0.592; p = 0.001). The mediation analysis showed that the use of ulinastatin was able to reduce the probability of death by 23.5%. The average causal mediation effect of delta C-reactive protein (CRP) was 8%, accounting for 35% of the total effect.

    Abstract Purpose: CD11b+Gr-1+ cells play a key role in inflammation and the purpose of this study was to determine whether splenic CD11b+Gr-1+ cells are mobilized to the kidney and lead to acute kidney injury during sepsis.
    Methods: The sepsis model was generated via cecum ligation and puncture (CLP). The mice were randomly distributed into control, sham operated, CLP and CLP+splenectomy (CLPS) groups (n=5-10/group). The percentage of CD11b+Gr-1+ cells in circulating, bone marrow and spleen were determined. Plasma concentrations of interleukin-6, interleukin-1β, creatinine (Cr) and neutrophil gelatinase-associated lipocalin were measured. CD11b+Gr-1+ cells were detected by immunofluorescence and qRT-PCR. Hematoxylin-eosin (HE) and periodic acid-Schiff (PAS) staining and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labelling (TUNEL) were performed. Expression of mammalian target of rapamycin (mTOR), hypoxia-inducible factor-1α (HIF-1α) and cleaved caspase-3 was measured.
    Results: The percentage of CD11b+Gr-1+ cells in blood was significantly higher in the CLP group and lower in CLPS group. CD11b+Gr-1+ cells in the spleen were significantly lower in the CLP group. In the CLP group, the plasma concentrations of interleukin-6, interleukin-1β, Cr and neutrophil gelatinaseassociated lipocalin were higher. The expression of Gr-1 and CD11b were higher in CLP. The CD11b+Gr-1+ cells were detected in the kidneys of the CLP group. HE, PAS and TUNEL showed inflammatory cell infiltration and cell apoptosis in CLP. Western blot indicated dephosphorylation of mTOR, down-expression of HIF-1α and increased expression of cleaved caspase-3 in sepsis kidney.
    Conclusion: Splenic CD11b+Gr-1+ cells migrated to the kidney in sepsis, which led to acute kidney injury via the inhibition of mTOR/HIF-1α.

    Abstract Objective Nonalcoholic Wernicke’s encephalopathy (WE) is a devastating neuropsychiatric syndrome caused by thiamine deficiency. Although many case reports on WE have been published, more studies are required to guide the diagnosis and treatment of nonalcoholic WE. Methods We retrospectively studied patients who were diagnosed with WE in our hospital. Data on demographics, possible causes, phenomenology, and diagnostic and treatment delays were abstracted from medical records by chart reviews. Results Seventeen patients were diagnosed with nonalcoholic WE. Nonalcoholic WE had many causes, such as gastrointestinal surgery, gastrointestinal tract diseases, vomiting, and psychiatric diseases. Most patients presented with abnormal mental symptoms, including those in a coma. Conclusion In summary, we recommend using operational criteria to diagnose and treat nonalcoholic WE as early as possible to avoid misdiagnosis and treatment delays. Nonalcoholic WE remains a clinical diagnosis, and certain examinations are helpful for this diagnosis, such as measuring serum thiamine concentrations. We should focus on patients who present with abnormal mental symptoms, even those in a coma, and administer parenteral thiamine before any carbohydrate to reduce the high frequency of residual morbidity.
