Automatic recognition of depression based on audio and video: A review.

Depression is a common mental health disorder. With current depression detection methods, specialized physicians often engage in conversations and physiological examinations based on standardized scales as auxiliary measures for depression assessment. Non-biological markers-typically classified as verbal or non-verbal and deemed crucial evaluation criteria for depression-have not been effectively utilized. Specialized physicians usually require extensive training and experience to capture changes in these features. Advancements in deep learning technology have provided technical support for capturing non-biological markers. Several researchers have proposed automatic depression estimation (ADE) systems based on sounds and videos to assist physicians in capturing these features and conducting depression screening. This article summarizes commonly used public datasets and recent research on audio- and video-based ADE based on three perspectives: Datasets, deficiencies in existing research, and future development directions.

Immediate Effects of Vergence Exercises Using Automatic Dual Rotational Risley Prisms on Accommodative Lag and Facility.

INTRODUCTION: This study evaluated novel automatic dual rotational Risley prisms (ADRRPs) as a vergence exercise tool for patients with myopia to improve accommodative lag and accommodative facility. METHODS: Participants with myopia aged 20-24 years were recruited. After vergence exercises with prisms (treatment group) or plano lenses (control group) using ADRRPs for 10 min, measurements were taken using an open-field autorefractor (Grand Seiko WAM-5500) at viewing distances of 0.4 m and 6.0 m. We measured accommodative facility using a ± 2.00 D accommodative flipper. RESULTS: A total of 56 participants (treatment group, 39; control group, 17) performed vergence exercises using ADRRPs. Participants in the treatment group showed improvements in accommodative lag at a 0.4 m viewing distance, with measurements of 0.57 D (right eye; OD) and 0.53 D (left eye; OS) and 0.21 D (OD) and 0.27 D (OS) before and after the exercises, respectively (p < 0.001). Over-refractions using an open-field autorefractor with spherical equivalent contact lenses at a 6.0 m viewing distance were - 0.01 ± 0.30 D (OD) and 0.03 ± 0.34 D (OS) and 0.15 ± 0.32 D (OD) and 0.19 ± 0.28 D (OS) before and after the exercises, respectively (difference + 0.16 D; p < 0.001). Accommodative facility values before and after exercises were 14.88 ± 3.36 and 15.59 ± 3.60 cpm, respectively (p < 0.01). No significant differences in accommodative lag, relaxation, and accommodative facility before and after exercise were observed in the control group. CONCLUSIONS: Using ADRRPs in vergence exercises can improve accommodative lag, accommodative facility, and accommodative relaxation in adults with myopia. Further research to evaluate persistent and long-term effects is needed.

Transglutaminase-Catalyzed Glycosylation Improved Physicochemical and Functional Properties of Lentinus edodes Protein Fraction.

Lentinula edodes has high nutritional value and abundant protein. In order to develop and utilize edible mushroom protein, this study was designed to investigate the effects of TGase-catalyzed glycosylation and cross-linking on the physicochemical and functional properties of Lentinus edodes protein fraction. The results showed that within a certain time, glycosylation and TGase-catalyzed glycosylation decreased the total sulfydryl, free sulfydryl, disulfide bond, surface hydrophobicity, ß-fold and α-helix, but increased the fluorescence intensity, random coil, ß-turn, particle size and thermal stability. The apparent viscosity and the shear stress of the protein with an increase in shear rate were increased, indicating that TGase-catalyzed glycosylation promoted the generation of cross-linked polymers. In addition, the TGase-catalyzed glycosylated proteins showed a compact texture structure similar to the glycosylated proteins at the beginning, indicating that they formed a stable three-dimensional network structure. The flaky structure of proteins became more and more obvious with time. Moreover, the solubility, emulsification, stability and oil-holding capacity of enzymatic glycosylated Lentinus edodes protein fraction were significantly improved because of the proper TGase effects of glycosylation grafting and cross-linking. These results showed that glycosylation and TGase-catalyzed glycosylation could improve the processing characteristics of the Lentinula edodes protein fraction to varying degrees.

Research progress on the effectiveness of smallpox vaccination against mpox virus infection / 中华流行病学杂志

With the expansion of mpox virus infection from endemic to a global epidemic in 2022, the WHO declared that the mpox event constituted a Public Health Emergency of International Concern. Due to the high degree of gene sequence similarity among orthopox viruses and cross-reactive antibodies induced by orthoviruses, smallpox vaccination may affect the immune response induced by mpox virus infection. The analysis of the protective effects of smallpox vaccination against mpox virus infection will help define the focus of prevention and control. In this review, we clarify the protection of the smallpox vaccine against mpox virus infection by analyzing the correlation between smallpox vaccination, immune response status, and clinical data and providing evidence for the prevention, control, and strategies of mpox epidemics.

Research progress on the effect of hyperthermia on vascular endothelial growth factor in tumor microenvironment / 中华放射肿瘤学杂志

Vascular endothelial growth factor (VEGF) plays an important role in promoting tumor vascular growth and changing vascular wall permeability. With the in-depth study of tumor hyperthermia and tumor microenvironment, more and more studies have shown that hyperthermia exerts multiple regulatory effects on VEGF in tumor microenvironment. Combined with current research progress in China and abroad, this article reviews the effect of hyperthermia on VEGF and its related cells and factors in tumor microenvironment, aiming to provide new ideas for the clinical application of tumor hyperthermia combined with immune or targeted therapy.

Effect of hyperthermia on biological behavior of squamous cell carcinoma of the tongue by regulating ferroptosis pathway / 中华放射肿瘤学杂志

Objective:To investigate the regulation and possible mechanism of hyperthermia (HT) on the ferroptosis of squamous cell carcinoma of the tongue cell line CAL-27.Methods:Half maximal inhibitory concentration (IC 50) of Fer-1, an inhibitor of ferroptosis, was detected by CCK-8 assay and used for subsequent experiments. CAL-27 cells were divided into the HT, control, Fer-1 and HT+ Fer-1 groups according to experimental design. Reactive oxygen species (ROS) levels and iron ion concentration were determined by corresponding detection kits. The p53 and TfR1 mRNA levels were detected by real-time reverse transcription PCR. Cell migration was detected by cell scratch test and cell apoptosis was detected by flow cytometry. Results:HT significantly up-regulated the ROS levels ( P<0.01) and iron ion concentration ( P<0.001), and significantly increased the expression levels of p53 and TfR1 mRNA (both P<0.01). The cell migration ability was decreased ( P<0.001), whereas cell apoptosis rate was increased by HT ( P<0.01). In the HT+Fer-1 group, the ROS levels ( P<0.001), iron ion concentration ( P<0.001), expression levels of p53 and TfR1 mRNA (both P<0.01) were significantly down-regulated, the cell migration ability was recovered ( P<0.01), and cell apoptosis rate was decreased ( P<0.01) compared with those in the HT group, respectively. Conclusions:HT may induce the ferroptosis of CAL-27 cell line, inhibit cell migration ability and promote cell apoptosis by activating the p53/TfR1 pathway.

Clinical research progress of human respiratory syncytial virus vaccine / 中华预防医学杂志

Human respiratory syncytial virus (HRSV) is one of the main pathogen causing severe acute lower respiratory tract infections in infants and the elderly, with high incidence rate and mortality worldwide. Vaccine is one of the important measure to prevent infection, transmission and severe disease of HRSV, but currently there is no officially approved preventive vaccine for prevention of HRSV in the world. This paper reviews and analyzes the current research and development progress of HRSV vaccine, summarizes the design routes of different types of HRSV preventive vaccines, and discusses the difficulties and challenges in vaccine research and development, in order to provide reference for the research and development of HRSV vaccine and the development of clinical trials.

Comprehensive genomic profiling of EWSR1/FUS::CREB translocation-associated tumors uncovers prognostically significant recurrent genetic alterations and methylation-transcriptional correlates.

To elucidate the mechanisms underlying the divergent clinicopathologic spectrum of EWSR1/FUS::CREB translocation-associated tumors, we performed a comprehensive genomic analysis of fusion transcript variants, recurrent genetic alterations (mutations, copy number alterations), gene expression, and methylation profiles across a large cohort of tumor types. The distribution of the EWSR1/FUS fusion partners-ATF1, CREB1, and CREM-and exon involvement was significantly different across different tumor types. Our targeted sequencing showed that secondary genetic events are associated with tumor type rather than fusion type. Of the 39 cases that underwent targeted NGS testing, 18 (46%) had secondary OncoKB mutations or copy number alterations (29 secondary genetic events in total), of which 15 (52%) were recurrent. Secondary recurrent, but mutually exclusive, TERT promoter and CDKN2A mutations were identified only in clear cell sarcoma (CCS) and associated with worse overall survival. CDKN2A/B homozygous deletions were recurrent in angiomatoid fibrous histiocytoma (AFH) and restricted to metastatic cases. mRNA upregulation of MITF, CDH19, PARVB, and PFKP was found in CCS, compared to AFH, and correlated with a hypomethylated profile. In contrast, S100A4 and XAF1 were differentially upregulated and hypomethylated in AFH but not CCS. Unsupervised clustering of methylation profiles revealed that CREB family translocation-associated tumors form neighboring but tight, distinct clusters. A sarcoma methylation classifier was able to accurately match 100% of CCS cases to the correct methylation class; however, it was suboptimal when applied to other histologies. In conclusion, our comprehensive genomic profiling of EWSR1/FUS::CREB translocation-associated tumors uncovered mostly histotype, rather than fusion-type associated correlations in transcript variants, prognostically significant secondary genetic alterations, and gene expression and methylation patterns.

Individual exposure to ambient PM2.5 and hospital admissions for COPD in 110 hospitals: a case-crossover study in Guangzhou, China.

Few studies have evaluated the short-term association between hospital admissions and individual exposure to ambient particulate matter (PM2.5). Particularly, no studies focused on hospital admissions for chronic obstructive pulmonary disease (COPD) at the individual level. We assessed the short-term effects of PM2.5 on hospitalization admissions for COPD in Guangzhou, China, during 2014-2015, based on satellite-derived estimates of ambient PM2.5 concentrations at a 1-km resolution near the residential address as individual-level exposure for each patient. Around 40,002 patients with COPD admitted to 110 hospitals were included in this study. A time-stratified case-crossover design with conditional logistic regression models was applied to assess the effects of PM2.5 based on a 1-km grid data of aerosol optical depth provided by the National Aeronautics and Space Administration on hospital admissions for COPD. Further, we performed stratified analyses by individual demographic characteristics and season of hospital admission. Around 10 µg/m3 increase in individual-level PM2.5 was associated with an increase of 1.6% (95% confidence interval [CI]: 0.6%, 2.7%) in hospitalization for COPD at a lag of 0-5 days. The impact of PM2.5 on hospitalization for COPD was greater significantly in males and patients admitted in summer. Our study strengthened the evidence for the adverse effect of PM2.5 based on satellite-based individual-level exposure data.

Effect of hyperthermia combined with paclitaxel on proliferation, apoptosis and cycle of human tongue squamous cell carcinoma cell line CAL-27 / 中华放射肿瘤学杂志

Objective:To observe the effect of hyperthermia combined with paclitaxel on the proliferation, apoptosis and cycle of human tongue squamous cell carcinoma cell line CAL-27, and to explore the underlying mechanism.Methods:The working concentration of paclitaxel was determined by CCK-8 assay, and the cultured CAL-27 cells were divided into the control, paclitaxel, 42℃ hyperthermia and combined treatment groups. The ability of cell proliferation was detected by colony formation assay, and the cell cycle and apoptosis were determined by flow cytometry. The expression levels of AKT, p-AKT, Bcl-2 and Bax proteins in each group were measured by Western blot.Results:Compared with the control group, the proliferation was significantly inhibited and the apoptosis of CAL-27 cells was significantly promoted in the combined treatment, hyperthermia and paclitaxel groups (all P<0.05), and the anti-proliferation and apoptosis-promoting effect in the combined treatment group was significantly better than those in the hyperthermia and paclitaxel groups (all P<0.05). Western blot showed that hyperthermia combined with paclitaxel could significantly up-regulate the expression level of Bax protein and significantly down-regulate the expression levels of P-AKT and Bcl-2 in CAL-27 cells (all P<0.05). Conclusions:Hyperthermia combined with paclitaxel can play a synergistic role in inhibiting proliferation and promoting apoptosis of tongue squamous cell carcinoma CAL-27 cells. The mechanism may be related to the inhibition of AKT activation and the activation of Bax/Bcl-2 apoptosis signaling pathway.

Differential Gene Expression and Biological Analyses of Primary Hepatocytes Following D-Chiro-Inositol Supplement.

Dietary supplements have improved the prevention of insulin resistance and metabolic diseases, which became a research hotspot in food science and nutrition. Obesity and insulin resistance, caused by a high-fat diet, eventually result in severe metabolic diseases, can be prevented with the dietary supplement D-chiro-inositol (DCI). In this work, we isolated mice primary hepatocytes with palmitic acid stimulation and DCI was applied to compare and contrast its effects of in primary hepatocyte biology. Before and after intervention with DCI, we used RNA-Seq technology to establish a primary hepatocyte transcriptome gene profile. We found that both PA and DCI cause a wide variation in gene expression. Particularly, we found that DCI plays critical role in this model by acting on glycolysis and gluconeogenesis. Overall, we generated extensive transcripts from primary hepatocytes and uncovered new functions and gene targets for DCI.

Generation of human embryonic stem cell models to exploit the EWSR1-CREB fusion promiscuity as a common pathway of transformation in human tumors.

Chromosomal translocations constitute driver mutations in solid tumors and leukemias. The mechanisms of how related or even identical gene fusions drive the pathogenesis of various tumor types remain elusive. One remarkable example is the presence of EWSR1 fusions with CREB1 and ATF1, members of the CREB family of transcription factors, in a variety of sarcomas, carcinomas and mesotheliomas. To address this, we have developed in vitro models of oncogenic fusions, in particular, EWSR1-CREB1 and EWSR1-ATF1, in human embryonic stem (hES) cells, which are capable of multipotent differentiation, using CRISPR-Cas9 technology and HDR together with conditional fusion gene expression that allows investigation into the early steps of cellular transformation. We show that expression of EWSR1-CREB1/ATF1 fusion in hES cells recapitulates the core gene signatures, respectively, of angiomatoid fibrous histiocytoma (AFH) and gastrointestinal clear cell sarcoma (GI-CCS), although both fusions lead to cell lethality. Conversely, expression of the fusions in hES cells differentiated to mesenchymal progenitors is compatible with prolonged viability while maintaining the core gene signatures. Moreover, in the context of a mesenchymal lineage, the proliferation of cells expressing the EWSR1-CREB1 fusion is further extended by deletion of the tumor suppressor TP53. We expect the generation of isogenic lines carrying oncogenic fusions in various cell lineages to expand our general understanding of how those single genetic events drive tumorigenesis while providing valuable resources for drug discovery.

Unclassified low grade spindle cell sarcoma with storiform pattern characterized by recurrent novel EWSR1/FUS-NACC1 fusions.

Despite extraordinary advances in the molecular characterization of soft tissue tumors as a result of the widespread application of next generation sequencing in clinical practice, a subset of lesions remain difficult to diagnose. In this study we describe 3 unclassified spindle cell sarcomas with a monomorphic cytomorphology and distinctive storiform growth, characterized by novel fusions between EWSR1 or FUS1, and NACC1 genes. The tumors occurred in 3 young adult females (age range: 29-31) involving deep soft tissues, two located in the lower extremity and one in the abdominal wall. All three tumors showed patchy positivity for S100 protein, while being negative for SOX10 and retained H3K27me3 expression. All cases were negative for epithelial or muscle markers. As the findings were non-specific, molecular studies using targeted panels of RNA sequencing were performed, including one case tested by TruSight RNA Fusion Panel and 2 cases by Archer FusionPlex. The results showed 2 cases were positive for FUS-NACC1 and one for EWSR1-NACC1 fusions. These findings were further confirmed by FISH using custom BAC probes for a dual-color fusion assay. These results suggest the possibility of a previously undescribed soft tissue neoplasm characterized by a uniform spindle cell phenotype arranged in a storiform and fascicular pattern, expressing S100 protein and harboring NACC1-related fusions. The biologic behavior of this tumor remains to be determined.

Pediatric Mesothelioma With ALK Fusions: A Molecular and Pathologic Study of 5 Cases.

Pediatric mesotheliomas are rare and their pathogenesis remains undefined. In this study, we report 5 cases of malignant mesothelioma in children, characterized by fusions involving the anaplastic lymphoma kinase (ALK) gene. Four cases occurred in females involving the abdominal cavity and were characterized by a pure epithelioid morphology. The fifth arose in the tunica vaginalis of a 15-year-old male and displayed a biphasic epithelioid-sarcomatoid phenotype. All cases demonstrated the classic morphologic and immunohistochemical features of malignant mesothelioma, including tubulopapillary architecture and cuboidal epithelioid cells with eosinophilic cytoplasm and uniform nuclei with vesicular chromatin. Immunohistochemically, all cases showed labeling for ALK, cytokeratins, WT1, and calretinin, while lacking expression of adenocarcinoma immunomarkers. Four cases demonstrated weak-moderate labeling for PAX8 protein, which resulted in diagnostic challenges with primary peritoneal serous carcinoma. The ALK genetic abnormalities were investigated by a combination of molecular methods. Archer FusionPlex was performed in 2 cases, showing fusions between ALK with either STRN or TPM1 genes, resulting in a transcript that retained the ALK kinase domain. One case was further studied by DNA targeted sequencing, but no additional genetic alterations were observed. In 1 case, cytogenetic analysis showed the presence of a t(2;15)(p23;q22) and fluorescence in situ hybridization confirmed the ALK gene break-apart. In the remaining 2 cases, ALK gene rearrangements were demonstrated by fluorescence in situ hybridization. Unlike adult mesotheliomas, which are tightly linked to asbestos exposure, often show loss of BAP1 expression and have complex karyotypes, ALK-rearranged mesothelioma appears to be similar to other fusion-positive mesotheliomas, such as those harboring EWSR1/FUS-ATF1 fusions, sharing significant morphologic overlap, occurring in young patients and displaying a simple, translocation-driven genetic profile.

Hyalinizing epithelioid tumors with OGT-FOXO fusions. A case report of a non-acral soft tissue mass harboring a novel FOXO4 gene rearrangement.

Recurrent fusions between OGT and members of the Forkhead box (FOXO) family of genes have been recently described in three cases of hyalinizing epithelioid acral soft tissue tumors in young adults showing co-expression for EMA and CD34. Despite the lack of an established myoepithelial lineage by immunohistochemistry, these lesions have been labeled as myoepithelioma-like due to their epithelioid phenotype and sclerotic background. In this study, we report a novel FOXO4-OGT fusion identified by targeted RNA sequencing in an unclassified shoulder soft tissue mass in a 40-year-old male. The tumor showed nodular foci of increased cellularity in a uniformly hyalinized background. The neoplastic cells were mainly epithelioid and focally spindled, with eosinophilic cytoplasm and indented nuclei with mild atypia. The tumor lacked significant mitotic activity and necrosis. Immunohistochemically, the tumor showed variable positivity for EMA, pan-CK, CD34, ERG and FLI1, while it was negative for CD31, S100, SOX10, desmin, and MUC4. INI1 expression was retained. Due to its unusual histology and conflicting immunoprofile, TruSight RNA fusion panel sequencing was performed which revealed a fusion between FOXO4 exon 2 to OGT exon 2. This is the first example of a soft tissue lesion harboring OGT-related fusions occurring in a non-acral location and associated with FOXO4 gene. Its line of differentiation and biologic potential remain uncertain.

Epithelioid hemangioma of bone harboring FOS and FOSB gene rearrangements: A clinicopathologic and molecular study.

The diagnosis of epithelioid hemangioma (EH) remains challenging due to its rarity, worrisome histologic features, and locally aggressive clinical and radiographic presentation. Especially in the bone, EH can be misdiagnosed as a malignant vascular neoplasm due its lytic, often destructive or multifocal growth, as well as atypical morphology. The discovery of recurrent FOS and FOSB gene fusions in the pathogenesis of most EH has strengthened its stand-alone classification, distinct from other malignant epithelioid vascular lesions, such as epithelioid hemangioendothelioma or angiosarcoma. In this study we investigate a group of molecularly confirmed skeletal EH by the presence of FOS or FOSB gene rearrangements to better define its clinical and pathologic characteristics within a homogenous molecular subset. The cohort included 38 patients (25 males, 13 females), with a mean age at diagnosis of 38 years (range, 4-75). Regional, multifocal presentation was noted in 10 cases. Only six cases were correctly recognized as EH by the referring institutions, while most were misdiagnosed as other vascular tumors. Of the 17 patients with follow-up data available, five patients (29%) developed local recurrence after marginal en bloc excision (n = 3) or curettage (n = 2). Local recurrence-free survival rates were 84% at 3 years and 38% at 5 years. No metastasis or disease-related death was identified. Imaging studies exhibited no specific features, showing cortical bone destruction and soft-tissue extension in 14 (38%) cases. FOS gene rearrangements were detected in 28 (74%) of cases, while FOSB rearrangements in 10 (26%) cases. Our results highlight the significant challenges encountered in establishing a correct diagnosis exclusive of the molecular testing, mainly due to its overlap to other malignant epithelioid vascular tumors. Skeletal EH emerges as a genetically defined locally aggressive vascular neoplasm, with a high rate of local recurrence, but lacking the propensity for distant spread.

Novel GATA6-FOXO1 fusions in a subset of epithelioid hemangioma.

The genetic hallmark of epithelioid hemangioma (EH) is the presence of recurrent gene fusions involving FOS and FOSB transcription factors, which occur in one-third of the cases. Certain clinical, pathologic, and genotypic correlations have been described, with FOS-related fusions being more often detected in skeletal and cellular variants of EH, while FOSB gene rearrangements are more commonly associated with atypical histologic features and penile location. These fusions are infrequently detected in the cutaneous or head and neck EH. Overall, two-thirds of EH lack these canonical fusions and remain difficult to classify, especially when associated with atypical features and/or clinical presentations. Triggered by an index case of an intravascular soft tissue EH with a novel GATA6-FOXO1 gene fusion by targeted RNA sequencing (Archer® FusionPlex® Sarcoma Panel), we have investigated 27 additional EH cases negative for FOS and FOSB gene rearrangements for this novel abnormality to determine its recurrent potential, and its association with clinical and pathologic features. Four additional EH cases were found to display GATA6-FOXO1 fusions (18%). There were three females and two males, with a mean age of 32 years old. Three lesions occurred in the head and neck (dura, nasopharyngeal, and cheek), one in the back and one in the leg. Two of these lesions were cutaneous and one was intravascular in the subcutis of the leg. Microscopically, the tumors showed a variegated morphology, with alternating vasoformative and solid components, extravasated red blood cells and mild to moderate cytologic atypia. None showed brisk mitotic activity or necrosis. Tumors were negative for FOS and FOSB by immunohistochemistry. In conclusion, we report a new GATA6-FOXO1 fusion in a subset of EH, with a predilection for skin, and head and neck location. The relationship of this novel molecular subset with the more common FOS/FOSB fusion-positive EH remains to be determined.

Angioimmunoblastic T-cell lymphoma complicated with Epstein-Barr virus-positive diffuse large B-cell lymphoma: report of two cases and review of literature / 白血病·淋巴瘤

Objective:To investigate the clinicopathological features, treatment and prognosis of patients with angioimmunoblastic T-cell lymphoma (AILT) complicated with Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (DLBCL).Methods:The clinical data of 2 cases of AILT with EBV-positive DLBCL in the Fifth Medical Center of PLA General Hospital were retrospectively analyzed, and the literature was reviewed.Results:One case of complex lymphoma (CL) developed from low fever with systemic superficial lymphadenopathy, the right axillary tumor biopsy showed that AILT complicated with EBV-positive DLBCL. After 8 cycles of chemotherapy, the patient reached unconfirmed complete remission, then received maintenance treatment with chidamide and survived until the deadline. Another case of discordant lymphoma began with subcutaneous nodules and then developed progressive enlargement of superficial lymph nodes. The pathological examination of subcutaneous nodule diagnosed as DLBCL, and the pathological examination of right inguinal lymph node diagnosed as AITL. After 7 cycles of chemotherapy, the patient died of hemophagocytic syndrome.Conclusions:AILT with EBV-positive DLBCL is rare. The main clinical symptom is AITL and the immunophenotypic characteristic indicates the presence of T cells and B cells. At the same time, the prognosis is poor, and the treatment strategy mainly depends on the lymphoma type with unfavorable prognosis.

Effects of mild moxibustion on intestinal microbiome and NLRP3 inflammasome in rats with 5-fluorouracil-induced intestinal mucositis / 中西医结合学报

OBJECTIVE@#The present study investigated how mild moxibustion treatment affects the intestinal microbiome and expression of NLRP3-related immune factors in a rat model of intestinal mucositis (IM) induced with 5-fluorouracil (5-Fu).@*METHODS@#Forty male Sprague-Dawley rats were randomly divided into control, chemotherapy, moxibustion and probiotics groups. The IM rat model was established by intraperitoneal injection of 5-Fu. Mild moxibustion treatment and intragastric probiotic administration were provided once daily for 15 days. Tissue morphology, serum levels of inflammatory factors and the expression levels of tight junction proteins, caspase-1, gasdermin D and NLRP3 were evaluated in colon tissue, through hematoxylin and eosin staining, electron microscopy, enzyme-linked immunosorbent assay, Western blotting, quantitative real-time reverse transcription polymerase chain reaction and immunofluorescence. Gut microbiome profiling was conducted through 16S rRNA amplicon sequencing.@*RESULTS@#Moxibustion and probiotic treatments significantly increased the expression levels of tight junction proteins, reduced cell apoptosis and the expression levels of caspase-1, gasdermin D and NLRP3; they also decreased the serum levels of tumor necrosis factor-α, interleukin (IL)-6, IL-1β and IL-18, while increasing serum levels of IL-10. Moxibustion and probiotic treatments also corrected the reduction in α-diversity and β-diversity in IM rats, greatly increased the proportion of the dominant bacterial genus Lactobacillus and reduced the abundance of the genera Roseburia and Escherichia in chemotherapy-treated rats to levels observed in healthy animals. We also found that these dominant genera were firmly correlated with the regulation of pyroptosis-associated proteins and inflammatory factors. Finally, moxibustion and probiotic treatments elicited similar effects in regulating intestinal host-microbial homeostasis and the expression of NLRP3 inflammasome-related factors.@*CONCLUSION@#Moxibustion exerts its therapeutic effect on IM by ameliorating mucosal damage and reducing inflammation. Moreover, moxibustion modulates the gut microbiota, likely via decreasing the expression levels of the NLRP3 inflammasome.
