Even with progress in comprehending the development of AF, the molecular connections between SD and AF are still not well-defined. The objective of this research was to pinpoint the shared molecular routes responsible for SD-induced AF and investigate possible treatment targets.Methods: Utilizing bioinformatics, we examined two transcriptome datasets from the Gene Expression Omnibus (GEO) database to pinpoint genes with differential expression (DEGs) common to SD and AF. Analyses focusing on functional enrichment, such as Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG), were conducted to pinpoint crucial biological mechanisms and pathways. Furthermore, we utilized immunofluorescence and Western blot techniques to evaluate YBX1 expression and its role in activating NLRP3 inflammasomes in a rat model induced by SD.Results: A total of 540 common DEGs were precisely identified between the AF and SD data collections. Studies emphasizing functional enrichment have highlighted the significance of inflammation pathways, particularly the NOD-like receptor signaling route. The application of machine learning uncovered four crucial genes—CDC5L, MAPK14, RAB5A, and YBX1—with YBX1 becoming the predominant gene in diagnostic processes. Investigating immune penetration revealed significant connections between YBX1 expression and specific immune cell types, notably CD8+ T cells and M1 macrophages. Live studies have demonstrated that SD amplifies the atrial electrical rearrangement, structural changes, the infiltration of inflammatory cells, and the heightened presence of YBX1 along with inflammasome elements.Conclusion: The research pinpoints YBX1 as a crucial gene in SD-related AF, possibly influencing its impact via the NOD-like receptor signaling route and the invasion of immune cells. The results offer crucial understanding of the molecular processes behind AF and propose YBX1 as a possible treatment focus to reduce the risk of AF caused by SD.Keywords: atrial fibrillation, sleep deprivation, bioinformatic analysis, inflammation, YBX1

Employing statistical methodologies including mean ± standard deviation, median, and one-sample t-test, the study sought to analyze and delineate factors associated with morbidity, such as age, childbirth, lactation, and body mass index (BMI).Results: The average age of the 724 patients was 33.4 ± 5.5 years. Among them 54.94% were aged 30– 39 years, 65.16% were within five years after delivery, and 62.56% were breastfeeding for less than 6 months. The BMI of patients aged 30– 39 years was higher than that of the general Chinese population (P < 0.05). There was no significant correlation between smoking, oral contraceptives, trauma, and the incidence of the disease in this group.Conclusion: Non-puerperal mastitis is more prevalent among women of childbearing age, specifically those aged 30– 39 years, who breastfed for less than 6 months within the first five years after childbirth. In this age group, higher BMI is linked to increased morbidity.Keywords: mastitis, clinical feature, non-puerperal, retrospective study, pathogenesis related factors

Subjects were identified by purposive sampling until code saturation. Semi-structured qualitative interviews were conducted with GPs, pharmacists, and patients from community health service centers in three urban districts of Beijing, China. The interviews were transcribed verbatim and the text was analysed using thematic analysis techniques including familiarising with data, generating initial codes, searching for themes, reviewing themes, defining and naming themes, and producing the report.Results: A total of eight GPs, seven pharmacists, and 18 outpatients were interviewed. Data analysis led to the generation of five key themes: (1) mutual trust between patient and GP, (2) communication with healthcare professionals, (3) acquisition of knowledge about medication safety, (4) implementation of medication self-management at home, and (5) different attitudes toward participation in medication decisions. Patients participated in medication safety in multiple ways. However, insufficient knowledge about medication safety, lack of awareness of the patient’s role in ensuring medication safety, shortage of consultation lengths, and being misled by some information were problems with patient participation in medication safety.Conclusion: This exploratory study contributes to our initial understanding of patient participation in medication safety. There were still many issues and barriers in the process of patient participation. Appropriate policies and measures, such as providing various forms of patient education, ensuring sufficient physician-patient communication, giving full play to the role of pharmacists, and making judicious use of digital health tools should be taken to improve medication safety by fully utilising the role of patients.Plain Language Summary: Medication safety is a significant concern around the world. Patient participation in the medication process is effective in reducing the incidence of medication errors and improving medication safety. However, the role of outpatients with chronic conditions in ensuring medication safety is often neglected. This study aims to explore the perspectives and experiences of GPs, pharmacists, and outpatients by qualitative interviews in Beijing, China. The study involved a series of interviews with eight GPs, seven pharmacists, and 18 outpatients living with noncommunicable diseases. The interview revealed five themes: (1) mutual trust between patient and GP, (2) communication with healthcare professionals, (3) acquisition of knowledge about medication safety, (4) implementation of medication self-management at home, and (5) different attitudes toward participation in medication decisions. The findings might help propose suggestions for patient participation in medication safety. Integrating these findings into future studies can help healthcare professionals formulate interventions and better support patients in participating in the medication process.Keywords: medication safety, patient participation, patient safety, qualitative study, noncommunicable disease, community health service centers

Some strains can cause food poisoning, and very few can cause clinically severe infections, leading to death. Here, we characterized the genome sequence of B. cereus LIN78 isolated from teeth with deep caries and compared it with those of 25 other related species.Methods: Third-generation sequencing technology, bacteriological analyses, biochemistry, and mass spectrometry were applied to characterize the drug-resistance genes and virulence factors of B. cereus LIN78.Results: The complete genome sequence of B. cereus Lin78 consists of 5647 genes distributed on a circular chromosome, a 393 kbp plasmid, and 928 pseudogenes (37.4% of whole-genome DNA). The LIN78 genome contains 14 sets of 16s, 23s, and 5s ribosomal RNA operons; 106 tRNA genes, one tmRNA, 12 genomic islands, six prophases, 64 repeats; 37 antibiotic-resistant genes; and 1119 putative virulence genes, including enterotoxins and cytolysins. The B. cereus LIN78 genome carries multiple copies of non-ribosomal polypeptide synthetase (NRPS) and post-translationally modified peptides (RiPPs). Phylogenetic analysis of the 26 B. cereus strains showed that B. cereus LIN78 is evolutionarily closely related to B. thuringiensis ATCC 10792 and B. cereus ATCC 14579.Conclusion: The newly isolated B. cereus carries many virulence genes, including enterotoxins and hemolysins, similar to B. anthracis, and multiple antibiotic resistance genes. These findings suggest that the strain has a potential risk of causing disease. Our studies are vital for further exploration of the evolution of B. cereus, its pathogenic mechanisms, and the control and treatment of bacterial infections.Keywords: bacillus cereus, whole-genome DNA sequencing, virulence factor, drug resistance gene, human teeth

Recombinant Human Granulocyte/Macrophage Colony-stimulating Factor (rhGM-CSF) is an immunomodulatory cytokine that has been mainly applied in the treatment of hematological diseases. Clinical evidence regarding GM-CSF in the treatment of diabetic lower extremity ulcers is limited. This study is the first case series that investigates the repurpose effects of rhGM-CSF on diabetic ulcer healing in real clinical practice.Methods: Nine patients diagnosed with diabetes and refractory lower extremity ulcer (ulcer duration ≥ 2 weeks) were included from September 2021 to February 2023 in the Division of Endocrinology, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology. Patients with Wagner grade ≥ 4 and SINDAD ≥ 5 were excluded. The included subjects were treated with rhGM-CSF plus standard of care (SOC) including glycemic control, foot care education, debridement of necrotic tissues, topical wound dressings, offloading, and infection control when necessary. The observation endpoint was complete epithelialization. Their clinical manifestations, laboratory tests, and therapeutic effects were extracted and analyzed.Results: The case series included 9 cases aged from 29 to 80 years and all the patients were male. Seven of 9 patients presented neuropathic ulcer. Only one case showed non-infected ulcer from tissue samples and one case presented ankle brachial index (ABI) < 0.9. It was observed that the ulcer areas among these 9 patients gradually declined throughout the whole treatment period with the average healing velocity 0.32 ± 013 cm2/day and the mean time to complete healing 16.0 ± 3.7 days. The relative area (percentage of initial ulcer area) decreased to 66.7 ± 13.0% on average after the first treatment. Ulcers in all the 9 patients achieved complete epithelialization after 4– 8 times treatments.Conclusion: The case series suggests rhGM-CSF as a promising therapeutic strategy for the treatment of diabetic ulceration. More robust data from randomized controlled trials are required to further evaluate its clinical efficacy.Keywords: recombinant human granulocyte/macrophage colony-stimulating factor, diabetic lower extremity ulcer, diabetic foot ulcer

However, there is limited research on the predisposition to MHR and prediabetes. Hence, we conducted a study to investigate the relationship between MHR and the prevalence of prediabetes.Methods: In total, 85,293 participants were included in our cross-sectional observational study. Multivariable regression analysis, subgroup analyses, and interaction testing were used to determine the relationship between MHR and prediabetes. To explore the non-linear association of MHR with prediabetes risk, generalized additive model (GAM) and smoothing splines were applied. The threshold effect analysis of MHR on the risk of prediabetes was further employed to identify the turning point.Results: After controlling for covariates, the results indicated that a positive correlation persisted between MHR and prediabetes (odds ratio (OR) =1.64, 95% confidence interval (CI), 1.48– 1.82), and subgroup analyses found a more robust correlation between MHR and prediabetes in individuals with lower age, SBP, DBP, TG, TC and higher values of BMI and LDL-C than in their counterparts. Additionally, the correlation between MHR and the risk of prediabetes was found to be non-linear, with a turning point of − 0.4 (Log-Likelihood Ratio, P< 0.001). The impact of variables on the two sides of the turning point were 1.94 (1.72, 2.19) and 0.88 (0.69, 1.14).Conclusion: The positive correlation between MHR and the risk of prediabetes in Chinese participants was observed to be non-linear, and MHR ≤ − 0.4 was strongly positively correlated with prediabetes risk.

Identifying novel and potential biomarkers is valuable in the treatment and diagnosis of psoriasis. The goal of this study was to identify novel key biomarkers of psoriasis and analyze the potential underlying mechanisms.Methods: Psoriasis-related datasets were downloaded from the Gene Expression Omnibus database to screen differential genes in the datasets. Functional and pathway enrichment analyses were performed on the differentially expressed genes (DEGs). Candidate biomarkers for psoriasis were identified from the GSE30999 and GSE6710 datasets using four machine learning algorithms, namely, random forest (RF), least absolute shrinkage and selection operator (LASSO) logistic regression, weighted gene co-expression network analysis (WGCNA), and support vector machine recursive feature elimination (SVM-RFE), and were validated using the GSE41662 dataset. Next, we used CIBERSORT and single-cell RNA analysis to explore the relationship between ADAM23 and immune cells. Finally, we validated the expression of the identified biomarkers expressions in human and mouse experiments.Results: A total of 709 overlapping DEGs were identified, including 426 upregulated and 283 downregulated genes. Enhanced by enrichment analysis, the differentially expressed genes (DEGs) were spatially arranged in relation to immune cell involvement, immune-activating processes, and inflammatory signals. Based on the enrichment analysis, the DEGs were mapped to immune cell involvement, immune-activating processes, and inflammatory signals. Four machine learning strategies and single-cell RNA sequencing analysis showed that ADAM23, a disintegrin and metalloprotease, may be a unique, critical biomarker with high diagnostic accuracy for psoriasis. Based on CIBERSORT analysis, ADAM23 was found to be associated with a variety of immune cells, such as macrophages and mast cells, and it was upregulated in the macrophages of psoriatic lesions in patients and mice.Conclusion: ADAM23 may be a potential biomarker in the diagnosis of psoriasis and may contribute to the pathogenesis by regulating immunological activity in psoriatic lesions.Keywords: psoriasis, machine learning, differential gene analysis, CIBERSORT, ADAM23

Kagome superconductors with TC up to 7 K have been discovered for over 40 y. Recently, unconventional chiral charge order has been reported in kagome superconductor KV3Sb5, with an ordering temperature of one order of magnitude higher than the TC. However, the chirality of the charge order has not been reported in the cousin kagome superconductor CsV3Sb5, and the electronic nature of the chirality remains elusive. In this paper, we report the observation of electronic chiral charge order in CsV3Sb5 via scanning tunneling microscopy (STM). We observe a 2 × 2 charge modulation and a 1 × 4 superlattice in both topographic data and tunneling spectroscopy. 2 × 2 charge modulation is highly anticipated as a charge order by fundamental kagome lattice models at van Hove filling, and is shown to exhibit intrinsic chirality. We find that the 1 × 4 superlattices form various small domain walls, and can be a surface effect as supported by our first-principles calculations. Crucially, we find that the amplitude of the energy gap opened by the charge order exhibits real-space modulations, and features 2 × 2 wave vectors with chirality, highlighting the electronic nature of the chiral charge order. STM study at 0.4 K reveals a superconducting energy gap with a gap size 2Δ=0.85meV, which estimates a moderate superconductivity coupling strength with 2Δ/kBTC=3.9. When further applying a c-axis magnetic field, vortex core bound states are observed within this gap, indicative of clean-limit superconductivity.

Logistic regression analysis and receiver operating characteristic (ROC) curves were applied to judge the accuracy of these novel biomarkers to predict in-hospital mortality.Results: Surviving AECOPD patients had lower NLR, PLR, and lymphocyte-to-monocyte ratios than non-survival patients (all P < 0.001). According to Pearson’s correlation test, there was a linear correlation between novel and traditional biomarkers (all P < 0.05). In terms of a single biomarker, the AUC value of NLR was the largest, which was not inferior to C-reactive protein (Z-P = 0.064), and superior to erythrocyte sedimentation rate (Z-P = 0.002) and other novel single inflammatory biomarkers (all Z-P < 0.05). The mortality of patients with NLR ≥ 4.43 was 2.308-fold higher than that of patients with NLR < 4.43. After dividing patients into a higher or lower NLR group, pooled results showed that patients with NLR ≥ 4.43 had a higher rate of treatment failure, intensive care unit admission, longer hospital length of stay, one-year mortality after the index hospitalization, and overall mortality than patients with NLR < 4.43 (all P < 0.001). Patients with NLR ≥ 4.43 were associated with higher and earlier first readmission due to AECOPD than patients with lower NLR.Conclusion: NLR was the best to forecast the clinical prognosis and readmission risk among AECOPD patients, which was not inferior to CRP, and the best cut-off value of NLR was 4.43.Keywords: acute exacerbations of chronic obstructive pulmonary disease, neutrophil–lymphocyte ratio, mortality, inflammatory biomarkers, readmission rate, treatment failure rate

In this study, we explore the use of unsteady transit time distribution (TTD) theory to model solute transport in biofilters, a popular form of nature-based or “green” storm water infrastructure (GSI). TTD theory has the potential to address many unresolved challenges associated with predicting pollutant fate and transport through these systems, including unsteadiness in the water balance (time-varying inflows, outflows, and storage), unsteadiness in pollutant loading, time-dependent reactions, and scale-up to GSI networks and urban catchments. From a solution to the unsteady age conservation equation under uniform sampling, we derive an explicit expression for solute breakthrough during and after one or more storm events. The solution is calibrated and validated with breakthrough data from 17 simulated storms at a field-scale biofilter test facility in Southern California, using bromide as a conservative tracer. TTD theory closely reproduces bromide breakthrough concentrations, provided that lateral exchange with the surrounding soil is accounted for. At any given time, according to theory, more than half of the water in storage is from the most recent storm, while the rest is a mixture of penultimate and earlier storms. Thus, key management endpoints, such as the pollutant treatment credit attributable to GSI, are likely to depend on the evolving age distribution of water stored and released by these systems.

However, natural bioactive substances suffer from poor water-solubility and poor stability in the physiological environment. Therefore, to overcome the drawbacks of natural bioactive substances in tumor therapy, there is an urgent need for an ideal nanocarrier to achieve high bioactive substance loading with low toxicity.Materials and Methods: Face-centered cubic hollow mesoporous Prussian Blue (HMPB) NPs were prepared by stepwise hydrothermal method. Among them, PVP served as a protective agent and HCl served as an etching agent. Firstly, MPB NPs were obtained by 0.01 M HCl etching. Then, the highly uniform dispersed HMPB NPs were obtained by further etching with 1 M HCl.Results: In this work, we report a pH-responsive therapeutic nanoplatform based on HMPB NPs. Surprisingly, as-prepared HMPB NPs with ultra-high bioactive substances loading capacity of 329 μg mg− 1 owing to the large surface area (131.67 m2 g− 1) and wide internal pore size distribution (1.8– 96.2 nm). Moreover, with the outstanding photothermal conversion efficiency of HMPB NPs (30.13%), natural bioactive substances were released in the tumor microenvironment (TME). HMPB@PC B2 achieved excellent synergistic therapeutic effects of photothermal therapy (PTT) and chemotherapy (CT) in vivo and in vitro without causing any extraneous side effects.Conclusion: A biocompatible HMPB@PC B2 nanoplatform was constructed by simple physical adsorption. The in vitro and in vivo experiment results demonstrated that the synergy of PTT/CT provided excellent therapeutic efficiency for cervical cancer without toxicity. Altogether, as-designed nanomedicines based on natural bioactive substances may be provide a promising strategy for cancer therapy.Graphical Abstract: Keywords: HMPB NPs, natural bioactive substances, synergistic therapy, negligible side effect

The most common symptom in UC patients was bloody stool (90.7%) followed by diarrhea (87.7%), mucus in stool (72.1%), and abdominal pain (66.3%), which were significantly different from those of CD patients (P < 0.01). In contrast, the most common symptom in CD patients was abdominal pain (80.0%) followed by diarrhea (58.4%), bloody stool (27.6%), and fever (18.2%). Erythrocyte sedimentation, C-reactive protein, and platelets were significantly increased, while hemoglobin was decreased, in the moderately or highly active IBD. The percentage of positive perinuclear anti-neutrophil cytoplasmic antibody was significantly higher in UC patients (31.1%) than that in CD patients (4.8%, P < 0.001), while the percentage of positive anti-intestinal goblet cell antibody was significantly higher in CD patients (23.1%) than that in UC patients (14.9%, P = 0.037).Conclusion: The findings of the current study may provide evidence-based information for Chinese gastroenterologists to treat IBD more effectively in the future.Keywords: inflammatory bowel disease, Crohn’s disease, ulcerative colitis

However, to our knowledge, the specific function of each of the E2Fs and their relation to the disease prognosis of colorectal cancer (CRC) patients remain unknown.Materials and Methods: We used different publicly available databases and tools, such as ONCOMINE, GEPIA2, UALCAN, cBioPortal, Kaplan–Meier plotter, Metascape, and TIMER analysis, to do an in silico exploration of the potential roles of E2Fs in CRC.Results: In our analyses, we found a downregulation of E2F2 expression and an upregulation of E2F1 and E2F3-8 expression in CRC tissues compared to normal controls. These findings were consistent with our subgroup analysis using the different clinicopathological features of CRC patients. Furthermore, overexpression of E2F3 and E2F4 were significantly correlated with worse overall survival (OS) in colon cancer patients. Meanwhile, low levels of E2F2 resulted in a shorter OS in rectal cancer patients. The E2F family members had varying degrees of genetic alterations with the highest alteration rate observed in E2F1 (23%). Interestingly, a moderate positive express correlation had been found in the following E2F family members: E2F1 with E2F4, E2F2 with E2F7, E2F2 with E2F8, and E2F7 with E2F8. In addition, spearman analysis revealed that E2Fs have a strong positive correlation with the critical oncogenes in CRC patients. Lastly, the expression of E2Fs was significantly associated with the infiltration of six immune cells.Conclusion: In this study, we found that E2F2, E2F3, and E2F4 have the potential to be novel prognostic biomarkers in CRC. The role of these E2F family members in disease pathology may be related to their functions in cell cycle regulation, therapeutic resistance, immune cell infiltration, and epithelia-to-mesenchymal transition. Further studies are required to validate our results; however, our findings may help provide a foundation for broadening our understanding of CRC pathology.Keywords: colorectal cancer, E2F, biomarkers, prognosis, bioinformatics

However, these applications require Au NPs to have excellent stability in different environments, such as extreme pH, high temperature, high concentration ions, and various biomatrix. To meet the requirement of multiple applications, many synthetic substances and natural products are used to prepare highly stable Au NPs. Because of this, we aim at offering an update comprehensive summary of preparation high stability Au NPs. In addition, we discuss its application in nanomedicine. The contents of this review are based on a balanced combination of our studies and selected research studies done by worldwide academic groups. First, we address some critical methods for preparing highly stable Au NPs using polymers, including heterocyclic substances, polyethylene glycols, amines, and thiol, then pay attention to natural product progress Au NPs. Then, we sum up the stability of various Au NPs in different stored times, ions solution, pH, temperature, and biomatrix. Finally, the application of Au NPs in nanomedicine, such as drug delivery, bioimaging, photothermal therapy (PTT), clinical diagnosis, nanozyme, and radiotherapy (RT), was addressed concentratedly.Keywords: high stability Au NPs, polymer, natural product, resistance, nanomedicine

Objectives: To determine the clinical course of fetal isolated non‐immune‐mediated second‐degree atrioventricular block (AVB) and the factors associated with spontaneous recovery in these cases. Methods: Fetuses with isolated non‐immune‐mediated second‐degree AVB were recruited prospectively between 2014 and 2022. These fetuses were divided into two groups: those which recovered spontaneously and those which did not. Maternal and fetal characteristics and intrauterine and postnatal outcomes were compared between the two groups. Results: The study cohort included 20 fetuses with isolated non‐immune‐mediated second‐degree AVB, diagnosed at a median gestational age of 22.0 (range, 17.0–35.0) weeks. In 12 fetuses, 1:1 atrioventricular conduction was restored spontaneously in utero and there was no recurrence during the postnatal follow‐up period. In the remaining eight fetuses, second‐degree AVB was maintained and, in six of these, the pregnancy was terminated on parental request. Of the two liveborn children who had persistent second‐degree AVB prenatally, one had progressed to complete AVB at the latest follow‐up, at the age of 34 months, but was asymptomatic, without heart enlargement or dysfunction. The other child progressed to complete AVB after delivery and was diagnosed with type‐2 long QT syndrome. This infant died aged 2 months. Fetuses in the group that recovered spontaneously had earlier gestational age at diagnosis (median, 20.0 (range, 17.0–26.0) vs 24.5 (range, 18.0–35.0) weeks; P = 0.004) and higher atrial rate at diagnosis (median, 147 (range, 130–160) vs 138 (range, 125–149) bpm; P = 0.006) in comparison with the group that did not recover spontaneously. The best cut‐off values for prediction of failure to recover spontaneously were 22.5 weeks' gestational age at diagnosis and 144 bpm atrial rate at diagnosis, with sensitivities of 87.5% and 75.0%, respectively, and specificities of 92.0% and 87.5%, respectively. Conclusions: The outcome of 60% of fetuses with isolated non‐immune‐mediated second‐degree AVB was favorable. Earlier gestational age and higher atrial rate at diagnosis were associated with spontaneous reversion to normal sinus rhythm. Prenatal genetic testing should be performed in cases with persistent AVB, to exclude heritable disorders including long QT syndrome. These findings provide important information for clinical management and prenatal counseling in these cases. © 2024 International Society of Ultrasound in Obstetrics and Gynecology.

Immunohistochemical (IHC) assays were performed to evaluate COTL1 expression in human GBM tissues and the clinical pathological analysis was performed. Colony formation and MTT assays were performed to evaluate the effects of COTL1 on GBM cell proliferation. Immunoblot assays were performed to detect the expression level of COTL1, Ki67, and PCNA. A xenograft model was developed in mice to assess the effects of COTL1 on tumor growth in vivo.Results: We found COTL1 had an obvious high expression in human GBM tissues. The expression of COTL1 was related to recurrence (P=0.006**) and prognosis of patients with GBM. Our data further demonstrated COTL1 promoted cell proliferation in vitro and contributed to tumor growth of GBM cells in mice.Conclusion: We therefore identified a novel and promising therapeutic target for the treatment of GBM.Keywords: coactosin-like protein, COTL1, glioblastoma), GBM, proliferation, recurrence, prognosis
