Abstract An anomalous origin of the pulmonary artery (AOPA) from the ascending aorta is a relatively rare but important cardiac malformation that frequently involves the right pulmonary artery (RPA). Its clinical manifestations depend mainly on the associated significant pulmonary hypertension, with an extremely high mortality rate in the first year of life. Here, we present a rare survival case of an 11-year-old child with the disease, who was hospitalized due to intermittent abdominal pain, but without any apparent signs of chest tightness or shortness of breath. The low oxygen saturation as discovered during the physical examination. Subsequent examination with transthoracic echocardiography (TTE) and pulmonary artery computed tomography angiography (CTA) revealed this unexpected congenital malformation. Although the estimated mean pulmonary artery pressure (MAP) from the TTE was 51 mmHg, which seemed to contraindicate corrective cardiac surgery, the limitations of TTE were considered. Consequently, after multidisciplinary consultation, surgical intervention was ultimately decided upon, resulting in a favorable prognosis for the patient. This case provides a new insight for clinicians in the diagnosis and treatment of complex congenital heart diseases.

Mesenchymal stem cells (MSCs) are highly plastic, with the capacity to differentiate into a spectrum of tissue-specific stromal cells. In the field of bone regeneration, MSCs have largely been considered for their osteogenic differentiation capacity. MSCs are increasingly being appreciated for their immunomodulatory potential following exposure to pro-inflammatory stimuli (licensing). Pro-inflammatory environments arise following bone injury via activation of resident immune cells like macrophages. We describe the use of a mineralized collagen scaffold as a bone-mimetic in vitro model to study the influence of paracrine versus direct cell-to-cell contact of THP-1 macrophages on MSC osteogenic and immunomodulatory potential. Paracrine stimuli from macrophages enhance MSC osteogenic and immunomodulatory potential via upregulation of key transcriptomic markers as well as via soluble biomolecule production. Direct co-culture of MSCs and macrophages decreased immunomodulatory potential in MSCs, especially for licensed MSCs, but enhanced matrix remodeling and expression of genes related to macrophage chemotaxis. These data demonstrate the significant effect macrophage-derived paracrine factors and direct contact have on MSC activity in a biomaterial model of bone regeneration. This work illuminates a critical need to further understand these processes in more clinically relevant cell models to inform biomaterial design.

Abstract Terrestrial geothermal springs, reminiscent of early Earth conditions, host diverse and abundant populations of Archaea. In this study, we reconstructed 2,949 metagenome-assembled genomes (MAGs) from 152 metagenomes collected over six years from 48 geothermal springs in Tengchong, China. Among these MAGs, 1,431 (49%) were classified as high-quality, while 1,518 (51%) were considered as medium-quality. Phylogenomic analysis revealed that these MAGs spanned 12 phyla, 27 classes, 67 orders, 147 families, 265 genera, and 475 species. Notably, 575 (19%) MAGs represented new taxa at various taxonomic levels, and 2,075 (70%) lacked nomenclature and effective descriptions. The most abundant phyla of archaeal genomes were Thermoproteota, Thermoplasmatota, and Micrarchaeota. The DRTY, ZMQ, and ZZQ geothermal springs were predominated by Archaea, particularly by Thermoproteia and Thermoplasmata. These draft genomes provide new data for studying species diversity and function within terrestrial geothermal spring archaeal communities, thus contributing to the conservation and utilization of thermophilic and hyperthermophilic microbial resources.

Abstract Global warming has accelerated lake salinization, driving changes in microbial community structure and function. However, the dynamics of viral communities in response to salinity remain unclear. Here, we apply metagenomic sequencing to a lake on the Qinghai–Tibet Plateau, spanning a broad salinity gradient, to investigate viral community dynamics. Our findings reveal that salinity strongly influences viral composition and modulates viral lifestyles. Temperate viruses increase in relative abundance along the salinity gradient, whereas virulent viruses show a corresponding decline. These shifts are mirrored in the prokaryotic communities, with Alphaproteobacteria and their infecting temperate viruses, notably Casadabanvirus, becoming more prevalent in higher salinity zones. Viral genomes encode genes associated with osmotic stress adaptation, DNA recombination, and nutrient transport, which may facilitate host adaptation to saline stress. This study provides valuable insights into the interplay between viral and prokaryotic communities in response to lake salinization.

Soy proteins (SPs), as vital plant-based proteins, hold significant promise for applications in food and medicine. However, their functional properties are limited due to their complex structures, which often fail to meet practical requirements.. With advancements in modern processing technologies, diverse protein modification techniques have been extensively investigated. This article reviews the effects of physical, chemical, and biological modification technologies on the structural and functional properties of SPs. It explores the mechanisms by which structural modifications improve functional properties and summarizes the current research on enhancing SP properties through combined modification techniques. Future research should focus on expanding the application potential of SPs and advancing the soybean industry.

Peritoneal dialysis is an effective renal replacement therapy for the treatment of end-stage renal disease. Prolonged peritoneal dialysis is prone to peritoneal inflammation， neoangiogenesis， and fibrosis， ultimately leading to interruption of peritoneal dialysis treatment. Recent studies have found that endoplasmic reticulum （ER） stress is closely related to peritoneal dialysis-associated complications. This article summarized the research progress of ER stress in peritoneal dialysis at home and abroad in recent years， mainly from the aspects of cell death， inflammatory signal transduction and epithelial-mesenchymal transition induced by ER stress through three classic signaling pathways， aiming to provide new ideas and directions for the prevention and treatment of peritoneal dialysis-related peritonitis and peritoneal fibrosis.

Objective To analyze the risk factors of ineffective platelet transfusion in leukemia, and explore the predictive value of human leukocyte antigen (HLA)-Ⅰ antibody and transforming growth factor-β1 (TGF-β1) for ineffective platelet transfusion in leukemia. Methods The clinical data of 108 patients with acute leukemia from January 2020 to September 2023 in Banan Hospital Affiliated to Chongqing Medical University were retrospectively analyzed. All patients were treated with platelet transfusion, and the expression of HLA-Ⅰ antibody and TGF-β1 was detected. The subjects were divided into ineffective group (38 cases) and effective group (70 cases) according to the effect of platelet transfusion.The general data, HLA-Ⅰ antibody and TGF-β1 of the two groups were compared, and the risk factors of ineffective platelet transfusion in leukemia were analyzed by logistic regression. The receiver operating characteristic (ROC) curve was drawn to analyze the predictive value of HLA-Ⅰ antibody and TGF-β1 for ineffective platelet transfusion in leukemia. Results A total of 1 575 platelets were transfused in 108 patients, and the effective rate of platelet transfusion was 68.00% (1071/1575). Logistic regression results showed that the number of transfusions＞6 times, infection, active bleeding, low positive bacterial culture, positive HLA-Ⅰ antibody, platelet count before transfusion, low TGF-β1 level were risk factors affecting the ineffectiveness of platelet transfusion in leukemia patients (P＜0.05). ROC curve analysis showed that the AUC of HLA-Ⅰ antibody and TGF-β1 a lone and combined predicting the ineffectiveness of platelet transfusion in leukemia patients was 0.748, 0.712, 0.812, and the sensitivity was 83.20%, 74.30%, 93.80%, respectively, with the combined prediction being the highest. Conclusion Positive HLA-Ⅰ antibodies and low TGF-β1 levels are risk factors for ineffective platelet transfusion in leukemia. Targeted intervention schemes can be used to intervene in patients with the above factors, in order to further improve the effect of platelet transfusion.

Abstract Resistance to gemcitabine in pancreatic ductal adenocarcinoma (PDAC) leads to ineffective chemotherapy and, consequently, delayed treatment, thereby contributing to poor prognosis. Glycolysis is an important intrinsic reason for gemcitabine resistance as it competitively inhibits gemcitabine activity by promoting deoxycytidine triphosphate accumulation in PDAC. However, biomarkers are lacking to determine which patients can benefit significantly from glycolysis inhibition under the treatment of gemcitabine activity, and a comprehensive understanding of the molecular mechanisms that promote glycolysis in PDAC will contribute to the development of a strategy to sensitize gemcitabine chemotherapy. In this study, we aimed to identify a biomarker that can robustly indicate the intrinsic resistance of PDAC to gemcitabine and guide chemotherapy sensitization strategies. After establishing gemcitabine-resistant cell lines in our laboratory and collecting pancreatic cancer and adjacent normal tissues from gemcitabine-treated patients, we observed that circRNA hsa_circ_0008383 (namely cNEK6) was highly expressed in the peripheral blood and tumor tissues of patients and xenografts with gemcitabine-resistant PDAC. cNEK6 enhanced resistance to gemcitabine by promoting glycolysis in PDAC. Specifically, cNEK6 prevented K48 ubiquitination of small ribonucleoprotein peptide A from the BTRC, a ubiquitin E3 ligase; thus, the accumulated SNRPA stopped PP2Ac translation by binding to its G-quadruplexes in 5′ UTR of mRNA. mTORC1 pathway was aberrantly phosphorylated and activated owing to the absence of PP2Ac. The expression level of cNEK6 in the peripheral blood and tumor tissues correlated significantly and positively with the activation of the mTORC1 pathway and degree of glycolysis. Hence, the therapeutic effect of gemcitabine is limited in patients with high cNEK6 levels, and in combination with the mTORC1 inhibitor, rapamycin, can enhance sensitivity to gemcitabine chemotherapy.

Abstract Acute type A aortic dissection (ATAAD) is a lethal pathological process within the aorta with high mortality and morbidity. T lymphocytes are perturbed and implicated in the clinical outcome of ATAAD, but the exact characteristics of T cell phenotype and its underlying mechanisms in ATAAD remain poorly understood. Here we report that CD4+ T cells from ATAAD patients presented with a hypofunctional phenotype that was correlated with poor outcomes. Whole transcriptome profiles showed that ferroptosis and lipid binding pathways were enriched in CD4+ T cells. Inhibiting ferroptosis or reducing intrinsic reactive oxygen species limited CD4+ T cell dysfunction. Mechanistically, CD36 was elevated in CD4+ T cells, whose blockade effectively alleviated palmitic acid-induced ferroptosis and CD4+ T cell hypofunction. Therefore, targeting the CD36-ferroptosis pathway to restore the functions of CD4+ T cells is a promising therapeutic strategy to improve clinical outcomes in ATAAD patients.

Abstract Background Cervical lymph node metastasis (CLNM) significantly impacts the prognosis of papillary thyroid carcinoma (PTC) patients. Accurate CLNM prediction is crucial for surgical planning and patient outcomes. This study aimed to develop and validate a nomogram-based risk stratification system to predict CLNM in PTC patients. Methods This retrospective study included 1069 patients from Zhongshan Hospital and 253 from the Qingpu Branch of Zhongshan Hospital. Preoperative ultrasound (US) data and various nodule characteristics were documented. Patients underwent lobectomy with central lymph node dissection and lateral dissection if suspicious. Multivariate logistic regression, least absolute shrinkage and selection operator (LASSO) regression, and the random forest algorithm were used to identify CLNM risk factors. A nomogram was constructed and validated internally and externally. Model performance was assessed via receiver operating characteristic (ROC) curves, calibration plots, DeLong’s test, decision curve analysis (DCA), and the clinical impact curve (CIC). Results Six independent CLNM risk factors were identified: age, sex, tumor size, calcification, internal vascularity, and US-reported CLNM status. The model's area under the curve (AUC) was 0.77 for both the training and the external validation sets. Calibration plots and Hosmer‒Lemeshow (HL) tests showed good calibration. The optimal cutoff value was 0.57, with a sensitivity of 58.02% and a specificity of 83.43%. Risk stratification on the basis of the nomogram categorized patients into low-, intermediate-, and high-risk groups, effectively differentiating the likelihood of CLNM, and an online calculator was created for clinical use. Conclusion The nomogram accurately predicts CLNM risk in PTC patients, aiding personalized surgical decisions and improving patient management.

Online asynchronous interaction is considered a core part of online teacher training, which has an important impact on learners' learning experience and learning outcomes. How to provide immediate and effective feedback through technical support based on the learners' interactive content and enhance interactive connection has become a key issue in massive online teacher training. This study designed an automated feedback framework from feedback strategy, feedback way, and feedback type. Then, we designed an emotional-cognitive feedback approach and an emotional-cognitive-metacognitive feedback approach based on automated analysis of online asynchronous interactions. A massive online teacher training course was conducted to provide automated feedback to 1438 learners in the online asynchronous interaction. Results showed that the two approaches enabled learners to interact more positively, slow down the growth of the dropout rate, and help learners adjust their emotional state and cognitive level. Particularly, the emotional-cognitive-metacognitive feedback approach could facilitate learners' self-regulation and improve feedback quality. Through questionnaires and semi-structured interviews, we found that learners were obsessed by automated emotional-cognitive-metacognitive feedback approach and they believed that it was helpful for their learning. This study is of great significance and application value to widely carry out high-quality, massive and personalized online learning.

BackgroundPhotobiomodulation, specifically high-energy photobiomodulation therapy (H-PBMT), is gaining recognition as a promising non-invasive intervention for managing knee osteoarthritis (KOA). While H-PBMT has demonstrated effectiveness in reducing pain and improving physical function, most evidence to date focuses on short-term symptomatic relief. The potential for H-PBMT to offer sustained benefits and modify the underlying progression of KOA remains insufficiently explored, warranting further investigation.ObjectiveThis study aims to assess the short-term and sustained effects of H-PBMT combined with rehabilitation exercises in patients with mild to moderate KOA, focusing on knee radiographic morphological changes over a 3-month follow-up period.MethodsThis protocol outlines a parallel-group, randomized, double-blind, placebo-controlled trial. Fifty participants with mild to moderate KOA (based on the Kellgren-Lawrence classification) will be randomly assigned to either the active H-PBMT plus exercise group (H-PBMT+E, n = 25) or the placebo photobiomodulation plus exercise group (PL+E, n = 25). Both groups will undergo an 8-week intervention, consisting of conventional rehabilitation exercises paired with either active or placebo photobiomodulation. H-PBMT will be delivered using the BTL-6000 HIL device with a 1064 nm wavelength, providing a total energy dose of 3190 J per 15-minute session. The treatment protocol includes both pulse mode (25 Hz, 5 W, 190 J) for analgesia and continuous mode (5 W, 3000 J) for biostimulation. Participants will be blinded to their group allocation through the use of a placebo device that mimics the active treatment without emitting therapeutic energy. Additionally, the outcome assessors will be blinded to the group allocations to ensure unbiased evaluation of the trial outcomes. The primary outcome is the Knee Injury and Osteoarthritis Outcome Score. Secondary outcomes include the Timed Up-and-Go test, Numerical Pain Rating Scale, and knee X-rays. Outcomes will be evaluated at baseline, immediately post-intervention (week 8), and at 3-month follow-up (week 20). Data will be analyzed according to the intention-to-treat principle, with a two-way repeated measures ANOVA used to assess time, group, and interaction effects.ConclusionThis study is expected to provide valuable insights into the sustained effects and potential disease-modifying properties of combining H-PBMT with rehabilitation exercises in managing KOA. The findings could inform more effective treatment protocols, improving rehabilitation outcomes and patient quality of life.Trial registrationAustralian New Zealand Clinical Trials Registry (ACTRN12624000699561p).

Objectives This study aimed to develop a prediction model for the detection of early sepsis-associated acute kidney injury (SA-AKI), which is defined as AKI diagnosed within 48 hours of a sepsis diagnosis.Design A retrospective study design was employed. It is not linked to a clinical trial. Data for patients with sepsis included in the development cohort were extracted from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database. The least absolute shrinkage and selection operator regression method was used to screen the risk factors, and the final screened risk factors were constructed into four machine learning models to determine an optimal model. External validation was performed using another single-centre intensive care unit (ICU) database.Setting Data for the development cohort were obtained from the MIMIC-IV 2.0 database, which is a large publicly available database that contains information on patients admitted to the ICUs of Beth Israel Deaconess Medical Center in Boston, Massachusetts, USA, from 2008 to 2019. The external validation cohort was generated from a single-centre ICU database from China.Participants A total of 7179 critically ill patients with sepsis were included in the development cohort and 269 patients with sepsis were included in the external validation cohort.Results A total of 12 risk factors (age, weight, atrial fibrillation, chronic coronary syndrome, central venous pressure, urine output, temperature, lactate, pH, difference in alveolar-arterial oxygen pressure, prothrombin time and mechanical ventilation) were included in the final prediction model. The gradient boosting machine model showed the best performance, and the areas under the receiver operating characteristic curve of the model in the development cohort, internal validation cohort and external validation cohort were 0.794, 0.725 and 0.707, respectively. Additionally, to aid interpretation and clinical application, SHapley Additive exPlanations techniques and a web version calculation were applied.Conclusions This web-based clinical prediction model represents a reliable tool for predicting early SA-AKI in critically ill patients with sepsis. The model was externally validated using another ICU cohort and exhibited good predictive ability. Additional validation is needed to support the utility and implementation of this model.

BackgroundKnee osteoarthritis (KOA) is a prevalent condition causing significant pain and functional impairment. Acupuncture has shown promise as an adjunctive therapy, but conventional manual selection of acupoints lacks standardization. The Acugraph system provides a computerized method for identifying acupoints, potentially enhancing treatment precision.ObjectiveThis study aims to compare the effects of computerized Acugraph-guided acupuncture versus manually selected acupuncture as adjuncts to physiotherapy in managing KOA.MethodsA randomized, double-blind controlled trial will be conducted with 50 participants diagnosed with mild to moderate KOA. Participants will be randomly assigned to one of two groups: Group 1 Comp-AcuPhysio (n = 25), receiving Acugraph-guided acupuncture with physiotherapy, or Group 2 Man-AcuPhysio (n = 25), receiving manually selected acupuncture with physiotherapy. Both groups will undergo 12 weekly treatment sessions, each lasting 60 minutes. Outcome measures, including the Knee Injury and Osteoarthritis Outcome Score, active knee flexion range, Timed Up and Go test, Visual Analog Scale for pain, Short Form-36 health survey, and Personal Integrated Energetics score, will be assessed at baseline and immediately post-intervention. An intention-to-treat analysis will be applied. Changes from baseline to 12 weeks will be analyzed using repeated measures analysis of variance for both within-group and between-group comparisons.ResultsThis study will provide a definitive assessment of the effectiveness of computerized Acugraph-guided acupuncture compared to manually selected acupuncture as supplementary treatments alongside KOA physiotherapeutic rehabilitation.ConclusionThis trial will offer insights into how incorporating technology-driven approaches, such as Acugraph, with physiotherapy can enhance the customization and effectiveness of KOA management, leading to improved clinical outcomes. These results could advocate for the integration of technological tools in acupuncture to boost treatment precision and efficacy for KOA.Trial registrationAustralian New Zealand Clinical Trials Registry (ACTRN12624000646549p).

Background Kangaroo mother care (KMC) is a care of preterm and low birthweight infants carried skin-to-skin contact with the mother’s chest and breastfeeding when possible. KMC has been proven to reduce mortality and morbidity in these infants. However, research on KMC has been limited by significant variability and inconsistency in reported outcomes across studies. These discrepancies hinder the inclusion of KMC clinical research in systematic reviews or meta-analyses, reducing its research value, leading to resource wastage and raising concerns about selective reporting biases. A core outcome set (COS), which defines a list of critical outcomes, can help harmonise the outcomes reported across studies in the same healthcare field. Further, how these outcomes should be measured and/or reported is defined in a core measurement set (CMS). This study aims to develop both a COS and a CMS for KMC to standardise outcome reporting, improve the quality assessments in clinical trials and facilitate data integration. This protocol outlines the methodology for developing a COS and CMS for KMC.Methods and analysis The development of the COS and CMS for KMC will follow six phases: (1) a systematic review, (2) semistructured interviews, (3) merging outcomes, (4) two/three rounds of international Delphi survey, (5) a consensus meeting and (6) development of the CMS. In phases 1 and 2, we will conduct a systematic review and semistructured interviews to identify potential core outcomes and measurements, which will form an initial outcome pool. In phase 3, these outcomes will be categorised into domains based on the core outcome measures for effectiveness (COMET) classification, creating a long list of outcomes for the Delphi survey. In phase 4, the Delphi survey will involve two/three rounds with key stakeholders, including neonatal clinical experts (including doctors and nurses), users of COS (including editors, public health experts, experts in evidence-based medicine and researchers), parents of neonates and policymakers, to refine the candidate core outcomes and measurements. In phase 5, an online consensus meeting with representatives of all stakeholders will finalise the COS. In phase 6, the CMS will be following Consensus-based Standards for the selection of health Measurement Instruments guidelines, which involve conceptual considerations, finding existing outcome measurement instruments, assessing their quality and selecting appropriate instruments for the COS. Parents of neonates will participate in phases 2, 4 and 5.Ethics and dissemination Ethical approval of this study has been granted by the Medical Ethics Committee of West China Second University Hospital (Medical Research 2024 ethics approval no. 167). The finalised COS and CMS will be disseminated through publication in peer-reviewed journals.Trial registration number We have registered the COS in the COMET database (http://www.comet-initiative.org/Studies/Details/2940).

BackgroundPeriviable infants are a highly vulnerable neonatal group, and their survival rates are considerably affected by patient-, caregiver-, and institution-level factors, exhibiting wide variability across different income countries and time periods. This study aims to systematically review the literature on the survival rates of periviable infants and compare rates among countries with varied income levels and across different time periods.MethodsComprehensive searches were conducted across MEDLINE, Embase, CENTRAL, and Web of Science. Cohort studies reporting survival outcomes by gestational age (GA) for periviable infants born between 22 + 0 and 25 + 6 weeks of gestation were considered. Paired reviewers independently extracted data and assessed the risk of bias and quality of evidence. Data pooling was achieved using random-effects meta-analyses.ResultsSixty-nine studies from 25 countries were included, covering 56,526 live births and 59,104 neonatal intensive care unit (NICU) admissions. Survival rates for infants born between 22 and 25 weeks of GA ranged from 7% (95% CI 5–10; 22 studies, n = 5,658; low certainty) to 68% (95% CI 63–72; 35 studies, n = 21,897; low certainty) when calculated using live births as the denominator, and from 30% (95% CI 25–36; 31 studies, n = 3,991; very low certainty) to 74% (95% CI 70–77; 48 studies, n = 17,664, very low certainty) for those admitted to NICUs. The survival rates improved over the two decades studied; however, stark contrasts were evident across countries with varying income levels.ConclusionAlthough the survival rates for periviable infants have improved over the past two decades, substantial disparities persist across different economic settings, highlighting global inequalities in perinatal health. Continued research and collaborative efforts are imperative to further improve the global survival and long-term outcomes of periviable infants, especially those in Low- and Middle-Income Countries.Systematic review registrationPROSPERO, CRD42022376367, available from: https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42022376367.

IntroductionThe involvement of thyroid hormone in cardiovascular disease remains debated. The aim of our research was to ascertain whether thyroid hormone sensitivity indices are related to carotid plaque (CAP) risk in the general population.MethodsWe recruited 5,360 participants for health examinations to explore the correlation between thyroid hormone sensitivity indices and CAP risk. We then compared baseline characteristics of participants with CAP to those without CAP based on multivariate logistic regression analysis. Additionally, we conducted subgroup analyses stratified by gender and age to further elucidate this relationship.ResultsAmong the 5,360 participants, 1,055 (19.7%) were diagnosed with CAP. After adjusting for various confounding factors, our results showed a positive association between CAP risk and the indices (TFQI, PTFQI, TSHI, and TT4RI). Conversely, the FT3/FT4 ratio showed a negative correlation with CAP risk. Sex-based subgroup analysis revealed a stronger correlation between thyroid hormone sensitivity and CAP in females compared to males. In the age subgroup, the significant association was observed in older individuals (age >60) compared to middle-aged participants (age ≤60).ConclusionOur study suggests a significant correlation between thyroid hormone sensitivity and CAP, particularly in females and participants over the age of 60.

Objective: Chronic atrophic gastritis (CAG) is a complex and burdensome disease. However, side effects and compliance issues cannot be ignored due to the long treatment cycle. Numerous studies have confirmed the effectiveness of rutaecarpine (RUT) for treating digestive dysfunction. However, the potential mechanism of action of RUT in the context of CAG treatment remains unclear. This study aimed to explore the therapeutic effects and mechanisms of RUT in 1-methyl-3-nitro-1-nitrosoguanidine-induced CAG using network pharmacology, metabolomics, and traditional pharmacological approaches. Materials and Methods: Pathological tests and ELISA assays were used to observe the therapeutic effects of RUT treatment on CAG. Differential metabolites were identified using ultra-high-performance liquid chromatography-tandem mass spectrometry, and metabolism-related target genes were enriched. The same target genes were identified between RUT and CAG diseases. The intersectional target genes were uploaded to Cytoscape for enrichment, and the nucleotide-binding oligomerization domain (NOD)-like receptor signaling pathway was selected to validate the mechanisms of the study. Finally, cell pyroptosis status was evaluated using the terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling assay, and the expressions of associated proteins of the NOD-like receptor signaling pathway were assessed by Western blotting and immunohistochemistry. Results: RUT alleviated gastric mucosal damage and significantly downregulated indicators associated with inflammation and gastric atrophy. A total of 29 intersection target genes was identified, and core pathways were obtained. The NOD-like receptor signaling pathway and pyroptosis status were selected to validate the mechanisms of RUT treatment in CAG rats. The expression of NOD-related proteins and downstream factors was downregulated in the RUT group. Conclusions: RUT exerts a pharmacological effect on relieving gastric damage in CAG rats by inhibiting NOD-like receptors and inflammasomes.
