Abstract
JOURNAL/nrgr/04.03/01300535-202508000-00002/figure1/v/2024-09-30T120553Z/r/image-tiff Traumatic brain injury is a prevalent disorder of the central nervous system. In addition to primary brain parenchymal damage, the enduring biological consequences of traumatic brain injury pose long-term risks for patients with traumatic brain injury; however, the underlying pathogenesis remains unclear, and effective intervention methods are lacking. Intestinal dysfunction is a significant consequence of traumatic brain injury. Being the most densely innervated peripheral tissue in the body, the gut possesses multiple pathways for the establishment of a bidirectional "brain-gut axis" with the central nervous system. The gut harbors a vast microbial community, and alterations of the gut niche contribute to the progression of traumatic brain injury and its unfavorable prognosis through neuronal, hormonal, and immune pathways. A comprehensive understanding of microbiota-mediated peripheral neuroimmunomodulation mechanisms is needed to enhance treatment strategies for traumatic brain injury and its associated complications. We comprehensively reviewed alterations in the gut microecological environment following traumatic brain injury, with a specific focus on the complex biological processes of peripheral nerves, immunity, and microbes triggered by traumatic brain injury, encompassing autonomic dysfunction, neuroendocrine disturbances, peripheral immunosuppression, increased intestinal barrier permeability, compromised responses of sensory nerves to microorganisms, and potential effector nuclei in the central nervous system influenced by gut microbiota. Additionally, we reviewed the mechanisms underlying secondary biological injury and the dynamic pathological responses that occur following injury to enhance our current understanding of how peripheral pathways impact the outcome of patients with traumatic brain injury. This review aimed to propose a conceptual model for future risk assessment of central nervous system-related diseases while elucidating novel insights into the bidirectional effects of the "brain-gut-microbiota axis."

DEN OPEN 2025; 5:e410. [PMID: 39035636 PMCID: PMC11258462 DOI: 10.1002/deo2.410] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 03/23/2024] [Revised: 06/27/2024] [Accepted: 06/30/2024] [Indexed: 07/23/2024]
Abstract
Objectives Although color information is important in gastrointestinal endoscopy, there are limited studies on how endoscopic images are viewed by people with color vision deficiency. We aimed to investigate the differences in the visibility of blood vessels during endoscopic submucosal dissection (ESD) among people with different color vision characteristics and to examine the effect of red dichromatic imaging (RDI) on blood vessel visibility. Methods Seventy-seven pairs of endoscopic images of white light imaging (WLI) and RDI of the same site were obtained during colorectal ESD. The original images were set as type C (WLI-C and RDI-C), a common color vision. These images were computationally converted to simulate images perceived by people with color vision deficiency protanope (Type P) or deutanope (Type D) and denoted as WLI-P and RDI-P or WLI-D and RDI-D. Blood vessels and background submucosa that needed to be identified during ESD were selected in each image, and the color differences between these two objects were measured using the color difference (ΔE 00) to assess the visibility of blood vessels. Results ΔE 00 between a blood vessel and the submucosa was greater under RDI (RDI-C/P/D: 24.05 ± 0.64/22.85 ± 0.66/22.61 ± 0.64) than under WLI (WLI-C/P/D: 22.26 ± 0.60/5.19 ± 0.30/8.62 ± 0.42), regardless of color vision characteristics. This improvement was more pronounced in Type P and Type D and approached Type C in RDI. Conclusions Color vision characteristics affect the visibility of blood vessels during ESD, and RDI improves blood vessel visibility regardless of color vision characteristics.

Abstract
Obscure gastrointestinal bleeding (OGIB), defined in 2010, involves bleeding from the GI tract that remains unexplained after standard diagnostic procedures. OGIB, which accounts for about 5% of all GI bleeds, poses diagnostic and management challenges, particularly due to the anatomical features of the small intestine. Advances in capsule endoscopy (CE) and balloon-assisted endoscopy have improved the diagnostic and therapeutic landscape for small intestinal lesions. Objective To determine the recurrence rate and identify risk factors for recurrence following diagnostic and therapeutic interventions using CE and balloon-assisted endoscopy in patients with OGIB. Methods A retrospective cohort study at Gifu University Hospital analyzed CE procedures for patients with OGIB from 2008 to 2022. Patients underwent CE with subsequent treatments based on the findings. Statistical analyses, including Kaplan-Meier and Cox proportional hazards models, were used to estimate cumulative recurrence rates and identify recurrence risk factors. Results Out of 417 patients, 65.2% had positive CE findings, leading to therapeutic interventions in 16.3% of cases. The cumulative recurrence rates at 12, 24, and 36 months were 4.3%, 9.0%, and 13.9%, respectively. Liver cirrhosis (hazard rate: 4.15, 95% confidence interval 1.88-9.18, p < 0.01) was identified as a significant risk factor for recurrence. Conclusions A significant recurrence rate in OGIB patients, with liver cirrhosis being a major risk factor. Despite diagnostic and therapeutic advances, a comprehensive approach including careful follow-up and consideration of risk factors is essential for management.

Safety and effectiveness of additional triamcinolone acetonide with endoscopic radial incision and cutting for benign stenosis of the lower gastrointestinal tract: A pilot study. DEN OPEN 2025; 5:e70002. [PMID: 39228860 PMCID: PMC11369793 DOI: 10.1002/deo2.70002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/19/2024] [Revised: 07/31/2024] [Accepted: 08/08/2024] [Indexed: 09/05/2024]
Abstract
Objectives Radial incision and cutting (RIC) is being investigated as an alternative endoscopic dilation method for lower intestinal tract stenosis, providing a high technical success rate and improving subjective symptoms. However, several patients develop re-stenosis following RIC. In this pilot study, we aimed to evaluate the safety and efficacy of triamcinolone acetonide (TA) addition after RIC. Methods RIC with TA was performed in 20 patients with lower gastrointestinal tract stenosis. We evaluated the rate of adverse events 2 months after RIC with TA. We investigated the short- and long-term prognoses, as well as the improvement in subjective symptoms, using a visual analog scale. Results The delayed bleeding rate after RIC was 23.8%. Endoscopic hemostasis was achieved in all patients with delayed bleeding. No perforations were observed. The cumulative re-stenosis-free, re-intervention-free, and surgery-free rates 1 year after RIC were 52.9%, 63.7%, and 85.2%, respectively. Subjective symptoms, including abdominal pain, abdominal bloating, nausea, and dyschezia, significantly improved after RIC with TA. Conclusion Although additional TA administration after RIC could be safe, additional TA may not be effective on luminal patency after dilation. Further investigation is warranted.

Gender disparities and woman-specific trends in Barrett’s esophagus in the United States: An 11-year nationwide population-based study. World J Methodol 2025; 15:97512. [DOI: 10.5662/wjm.v15.i1.97512] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2024] [Revised: 07/25/2024] [Accepted: 07/29/2024] [Indexed: 09/29/2024] Open
Abstract
BACKGROUND Barrett's esophagus (BE) is a known premalignant precursor to esophageal adenocarcinoma (EAC). The prevalence rates continue to rise in the United States, but many patients who are at risk of EAC are not screened. Current practice guidelines include male gender as a predisposing factor for BE and EAC. The population-based clinical evidence regarding female gender remains limited.
AIM To study comparative trends of gender disparities in patients with BE in the United States.
METHODS A nationwide retrospective study was conducted using the 2009-2019 National Inpatient Sample (NIS) database. Patients with a primary or secondary diagnosis code of BE were identified. The major outcome of interest was determining the gender disparities in patients with BE. Trend analysis for respective outcomes for females was also reported to ascertain any time-based shifts.
RESULTS We identified 1204190 patients with BE for the study period. Among the included patients, 717439 (59.6%) were men and 486751 (40.4%) were women. The mean age was higher in women than in men (67.1 ± 0.4 vs 66.6 ± 0.3 years, P < 0.001). The rate of BE per 100000 total NIS hospitalizations for males increased from 144.6 in 2009 to 213.4 in 2019 (P < 0.001). The rate for females increased from 96.8 in 2009 to 148.7 in 2019 (P < 0.001). There was a higher frequency of obesity among women compared to men (17.4% vs 12.6%, P < 0.001). Obesity prevalence among females increased from 12.3% in 2009 to 21.9% in 2019 (P < 0.001). A lower prevalence of smoking was noted in women than in men (20.8% vs 35.7%, P < 0.001). However, trend analysis showed an increasing prevalence of smoking among women, from 12.9% in 2009 to 30.7% in 2019 (P < 0.001). Additionally, there was a lower prevalence of alcohol abuse, Helicobacter pylori (H. pylori), and diabetes mellitus among females than males (P < 0.001). Trend analysis showed an increasing prevalence of alcohol use disorder and a decreasing prevalence of H. pylori and diabetes mellitus among women (P < 0.001).
CONCLUSION The prevalence of BE among women has steadily increased from 2009 to 2019. The existing knowledge concerning BE development has historically focused on men, but our findings show that the risk in women is not insignificant.

Abstract
The complex interplay of epigenetic factors is essential in regulating the hallmarks of cancer and orchestrating intricate molecular interactions during tumor progression. Circular RNAs (circRNAs), known for their covalently closed loop structures, are non-coding RNA molecules exceptionally resistant to enzymatic degradation, which enhances their stability and regulatory functions in cancer. Similarly, microRNAs (miRNAs) are endogenous non-coding RNAs with linear structures that regulate cellular biological processes akin to circRNAs. Both miRNAs and circRNAs exhibit aberrant expressions in various cancers. Notably, circRNAs can function as sponges for miRNAs, influencing their activity. The circRNA/miRNA interaction plays a pivotal role in the regulation of cancer progression, including in brain, gastrointestinal, gynecological, and urological cancers, influencing key processes such as proliferation, apoptosis, invasion, autophagy, epithelial-mesenchymal transition (EMT), and more. Additionally, this interaction impacts the response of tumor cells to radiotherapy and chemotherapy and contributes to immune evasion, a significant challenge in cancer therapy. Both circRNAs and miRNAs hold potential as biomarkers for cancer prognosis and diagnosis. In this review, we delve into the circRNA-miRNA circuit within human cancers, emphasizing their role in regulating cancer hallmarks and treatment responses. This discussion aims to provide insights for future research to better understand their functions and potentially guide targeted treatments for cancer patients using circRNA/miRNA-based strategies.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Smilax glabra rhizome has a long history been used for clinical purposes in traditional Chinese medicinal for treating various inflammatory conditions. Engeletin1 (ENG) is one of the most abundant bioactive compounds found in Smilax glabra rhizome, with anti-inflammatory, antioxidant, and ulcer-preventing activities. AIM OF THE STUDY The purpose of this study was to investigate the ability of ENG to alleviate inflammatory symptoms and improve epithelial barrier integrity utilize a 2,4,6-trinitrobenzene sulfonic acid2 (TNBS)-induced murine model in Crohn's disease3 (CD)-like colitis, and to characterize the underlying anti-inflammatory mechanisms of action. MATERIALS AND METHODS A colitis model was established in BALB/c mice and treated with ENG for 7 days. RAW264.7 macrophages were pre-treated with ENG and lipopolysaccharide4 (LPS) stimulation. The mice's weight and colon length were assessed. qPCR and Western blotting were used to analyze gene expression and TLR4-NFκB pathway. Flow cytometry was used to analyze the polarization states of the macrophages. RESULTS Treatment with ENG was sufficient to significantly alleviate symptoms of inflammation and colonic epithelial barrier integrity in treated mice. Significant inhibition of TNF-α, IL-1β, and IL-6 expression was observed following ENG treatment in vivo and in vitro. ENG was also determined to be capable of inhibiting the expression of iNOS and CD86, inhibited M1 macrophage polarization in vitro, as well as the TLR4-NFκB signaling pathway. Molecular docking showed a highly stable binding between ENG and TLR4. CONCLUSION ENG has been proven to alleviate inflammation and ameliorate the damage of epithelial barrier in CD-like colitis. ENG also suppressed the M1 macrophages polarization and the inhibited inflammatory cytokines. TLR4-NFκB signaling pathway, especially TLR4, may be the target of ENG. These data offer a new insight into the therapeutic mechanisms of ENG.

JOURNAL OF ETHNOPHARMACOLOGY 2025; 336:118711. [PMID: 39181286 DOI: 10.1016/j.jep.2024.118711] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/09/2024] [Revised: 08/08/2024] [Accepted: 08/17/2024] [Indexed: 08/27/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE According to the theory of Qi and blood in Traditional Chinese Medicine (TCM), the combination of Qi-reinforcing herbs and blood-activating herbs has a synergistic effect in improving blood stasis syndrome, especially in tumor treatment. The classic "Radix Astragali - Salvia miltiorrhiza" duo exemplifies this principle, renowned for invigorating Qi and activating blood flow, employed widely in tumor therapies. Our prior research underscores the potent inhibition of pancreatic tumor xenografts by the combination of Formononetin (from Radix Astragali) and Salvianolic acid B (from Salvia miltiorrhiza) in vitro. However, it remains unclear whether this combination can inhibit the abnormal vascularization of pancreatic tumors to achieve its anti-cancer effect. AIM OF THE STUDY Abnormal vasculature, known to facilitate tumor growth and metastasis. Strategies to normalize tumor-associated blood vessels provide a promising avenue for anti-tumor therapy. This study aimed to unravel the therapeutic potential of Formononetin combined with Salvianolic acid B (FcS) in modulating pancreatic cancer's impact on endothelial cells, illuminate the underlying mechanisms that govern this therapeutic interaction, thereby advancing strategies to normalize tumor vasculature and combat cancer progression. MATERIALS AND METHODS A co-culture system involving Human Umbilical Vein Endothelial Cells (HUVECs) and PANC-1 cells was established to investigate the potential of targeting abnormal vasculature as a novel anti-tumor therapeutic strategy. We systematically compared HUVEC proliferation, migration, invasion, and lumenogenesis in both mono- and co-culture conditions with PANC-1 (H-P). Subsequently, FcS treatment of the H-P system was evaluated for its anti-angiogenic properties. Molecular docking was utilized to predict the interactions between Formononetin and Salvianolic acid B with RhoA, and the post-treatment expression of RhoA in HUVECs was assessed. Furthermore, we utilized shRhoA lentivirus to elucidate the role of RhoA in FcS-mediated effects on HUVECs. In vivo, a zebrafish xenograft tumor model was employed to assess FcS's anti-tumor potential, focusing on cancer cell proliferation, migration, apoptosis, and vascular development. RESULTS FcS treatment demonstrated a significant, dose-dependent inhibition of PANC-1-induced alterations in HUVECs, including proliferation, migration, invasion, and tube formation capabilities. Molecular docking analyses indicated potential interactions between FcS and RhoA. Further, FcS treatment was found to downregulate RhoA expression and modulated the PI3K/AKT signaling pathway in PANC-1-induced HUVECs. Notably, the phenotypic inhibitory effects of FcS on HUVECs were attenuated by RhoA knockdown. In vivo zebrafish studies validated FcS's anti-tumor activity, inhibiting cancer cell proliferation, metastasis, and vascular sprouting, while promoting tumor cell apoptosis. CONCLUSIONS This study underscores the promising potential of FcS in countering pancreatic cancer-induced endothelial alterations. FcS exhibits pronounced anti-abnormal vasculature effects, potentially achieved through downregulation of RhoA and inhibition of the PI3K/Akt signaling pathway, thereby presenting a novel therapeutic avenue for pancreatic cancer management.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Pogostemonis Herba has long been used in traditional Chinese medicine to treat inflammatory disorders. Patchouli essential oil (PEO) is the primary component of Pogostemonis Herba, and it has been suggested to offer curative potential when applied to treat ulcerative colitis (UC). However, the pharmacological mechanisms of PEO for treating UC remain to be clarified. AIM OF THE STUDY To elucidate the pharmacological mechanisms of PEO for treating UC. METHODS AND RESULTS In the present study, transcriptomic and network pharmacology approaches were combined to clarify the mechanisms of PEO for treating UC. Our results reveal that rectal PEO administration in UC model mice significantly alleviated symptoms of UC. In addition, PEO effectively suppressed colonic inflammation and oxidative stress. Mechanistically, PEO can ameliorate UC mice by modulating gut microbiota, inhibiting inflammatory targets (OPTC, PTN, IFIT3, EGFR, and TLR4), and inhibiting the PI3K-AKT pathway. Next, the 11 potential bioactive components that play a role in PEO's anti-UC mechanism were identified, and the therapeutic efficacy of the pogostone (a bioactive component) in UC mice was partially validated. CONCLUSION This study highlights the mechanisms through which PEO can treat UC, providing a rigorous scientific foundation for future efforts to develop and apply PEO for treating UC.

JOURNAL OF ETHNOPHARMACOLOGY 2025; 336:118743. [PMID: 39209000 DOI: 10.1016/j.jep.2024.118743] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/01/2024] [Revised: 08/19/2024] [Accepted: 08/25/2024] [Indexed: 09/04/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Non-alcoholic fatty liver disease (NAFLD) is the leading cause of liver-related morbidity and mortality, with hepatic steatosis being the hallmark symptom. Salvia miltiorrhiza Bunge (Smil, Dan-Shen) and Ligusticum striatum DC (Lstr, Chuan-Xiong) are commonly used to treat cardiovascular diseases and have the potential to regulate lipid metabolism. However, whether Smil/Lstr combo can be used to treat NAFLD and the mechanisms underlying its lipid-regulating properties remain unclear. PURPOSE To assess the feasibility and reliability of a short-term high-fat diet (HFD) induced zebrafish model for evaluating hepatic steatosis phenotype and to investigate the liver lipid-lowering effects of Smil/Lstr, as well as its active components. METHODS The phenotypic alterations of liver and multiple other organ systems were examined in the HFD zebrafish model using fluorescence imaging and histochemistry. The liver-specific lipid-lowering effects of Smil/Lstr combo were evaluated endogenously. The active molecules and functional mechanisms were further explored in zebrafish, human hepatocytes, and hamster models. RESULTS In 5-day HFD zebrafish, significant lipid accumulation was detected in the blood vessels and the liver, as evidenced by increased staining with Oil Red O and fluorescent lipid probes. Hepatic hypertrophy was observed in the model, along with macrovesicular steatosis. Smil/Lstr combo administration effectively restored the lipid profile and alleviated hepatic hypertrophy in the HFD zebrafish. In oleic-acid stimulated hepatocytes, Smil/Lstr combo markedly reduced lipid accumulation and cell damage. Subsequently, based on zebrafish phenotypic screening, the natural phthalide senkyunolide I (SEI) was identified as a major molecule mediating the lipid-lowering activities of Smil/Lstr combo in the liver. Moreover, SEI upregulated the expression of the lipid metabolism regulator PPARα and downregulated fatty acid translocase CD36, while a PPARα antagonist sufficiently blocked the regulatory effect of SEI on hepatic steatosis. Finally, the roles of SEI on hepatic lipid accumulation and PPARα signaling were further verified in the hamster model. CONCLUSIONS We proposed a zebrafish-based screening strategy for modulators of hepatic steatosis and discovered the regulatory roles of Smil/Lstr combo and its component SEI on liver lipid accumulation and PPARα signaling, suggesting their potential value as novel candidates for NAFLD treatment.

Uncovering the mechanisms of Zhubi decoction against rheumatoid arthritis through an integrated study of network pharmacology, metabolomics, and intestinal flora. JOURNAL OF ETHNOPHARMACOLOGY 2025; 336:118736. [PMID: 39186991 DOI: 10.1016/j.jep.2024.118736] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/15/2024] [Revised: 08/22/2024] [Accepted: 08/23/2024] [Indexed: 08/28/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Zhubi Decoction (ZBD) is a modified formulation derived from the classic traditional Chinese medicine prescription "Er-Xian Decoction" documented in the esteemed "Clinical Manual of Chinese Medical Prescription". While the utilization of ZBD has exhibited promising clinical outcomes in treating rheumatoid arthritis (RA), the precise bioactive chemical constituents and the underlying mechanisms involved in its therapeutic efficacy remain to be comprehensively determined. AIM OF THE STUDY This study aims to systematically examine ZBD's pharmacological effects and molecular mechanisms for RA alleviation. MATERIALS AND METHODS Utilizing the collagen-induced arthritis (CIA) rat model, we comprehensively evaluated the anti-rheumatoid arthritis effects of ZBD in vivo through various indices, such as paw edema, arthritis index, ankle diameter, inflammatory cytokine levels, pathological conditions, and micro-CT analysis. The UPLC-MS/MS technique was utilized to analyze the compounds of ZBD. The potential therapeutic targets and signaling pathways of ZBD in the management of RA were predicted using network pharmacology. To analyze comprehensive metabolic profiles and identify underlying metabolic pathways, we conducted a serum-based widely targeted metabolomics analysis utilizing LC-MS technology. Key targets and predicted pathways were further validated using immunofluorescent staining, which integrated findings from serum metabolomics and network pharmacology analysis. Additionally, we analyzed the gut microbiota composition in rats employing 16 S rDNA sequencing and investigated the effects of ZBD on the microbiota of CIA rats through bioinformatics and statistical methods. RESULTS ZBD exhibited remarkable efficacy in alleviating RA symptoms in CIA rats without notable side effects. This included reduced paw redness and swelling, minimized joint damage, improved the histopathology of cartilage and synovium, mitigated the inflammatory state, and lowered serum concentrations of cytokines TNF-α, IL-1β and IL-6. Notably, the effectiveness of ZBD was comparable to MTX. Network pharmacology analysis revealed inflammation and immunity-related signaling pathways, such as PI3K/AKT, MAPK, IL-17, and TNF signaling pathways, as vital mediators in the effectual mechanisms of ZBD. Immunofluorescence analysis validated ZBD's ability to inhibit PI3K/AKT pathway proteins. Serum metabolomics studies revealed that ZBD modulates 170 differential metabolites, partially restored disrupted metabolic profiles in CIA rats. With a notable impact on amino acids and their metabolites, and lipids and lipid-like molecules. Integrated analysis of metabolomics and network pharmacology identified 6 pivotal metabolite pathways and 3 crucial targets: PTGS2, GSTP1, and ALDH2. Additionally, 16 S rDNA sequencing illuminated that ZBD mitigated gut microbiota dysbiosis in the CIA group, highlighting key genera such as Ligilactobacillus, Prevotella_9, unclassified_Bacilli, and unclassified_rumen_bacterium_JW32. Correlation analysis disclosed a significant link between 47 distinct metabolites and specific bacterial species. CONCLUSION ZBD is a safe and efficacious TCM formulation, demonstrates efficacy in treating RA through its multi-component, multi-target, and multi-pathway mechanisms. The regulation of inflammation and immunity-related signaling pathways constitutes a crucial mechanism of ZBD's efficacy. Furthermore, ZBD modulates host metabolism and intestinal flora. The integrated analysis presents experimental evidence of ZBD for the management of RA.

Triterpenes from Ganoderma lucidum inhibit hepatocellular carcinoma by regulating enhancer-associated lncRNA in vivo. JOURNAL OF ETHNOPHARMACOLOGY 2025; 336:118706. [PMID: 39186989 DOI: 10.1016/j.jep.2024.118706] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/24/2024] [Revised: 07/29/2024] [Accepted: 08/17/2024] [Indexed: 08/28/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ganoderma lucidum (G. lucidum) has been widely used as adjuvant of anti-tumor therapy for variety tumors. The bioactive ingredients of G. lucidum mainly include triterpenes, such as Ganoderic acid A, Ganoderic acid B, Ganoderenic acid A, Ganoderenic acid B, Ganoderenic acid D, and Ganoderic acid X. However, the effects and underlying mechanisms of G. lucidum are often challenging in hepatocellular carcinoma (HCC) treatment. AIM OF THE STUDY To explore the potential role and mechanism of enhancer-associated lncRNAs (en-lncRNAs) in G. lucidum treated HCC through the in vivo and in vitro experiments. MATERIALS AND METHODS Hepa1-6-bearing C57 BL/6 mice model were established to evaluate the therapeutic efficacy of G. lucidum treated HCC. Ki67 and TUNEL staining were used to detect the tumor cell proliferation and apoptosis in vivo. The Mouse lncRNA 4*180K array was implemented to identify the differentially expressed (DE) lncRNAs and mRNAs of G. lucidum treated tumor mice. The constructed lncRNA-mRNA co-expression network and bioinformatics analysis were used to selected core en-lncRNAs and its neighboring genes. The UPLC-MS method was used to identify the triterpenes of G. lucidum, and the in vitro experiments were used to verify which triterpene monomers regulated en-lncRNAs in tumor cells. Finally, a stable knockdown/overexpression cell lines were used to confirm the relationship between en-lncRNA and neighboring gene. RESULTS Ki67 and TUNEL staining demonstrated G. lucidum significantly inhibited tumor growth, suppressed cell proliferation and induced apoptosis in vivo. Transcriptomic analysis revealed the existence of 126 DE lncRNAs high correlated with 454 co-expressed mRNAs in G. lucidum treated tumor mice. Based on lncRNA-mRNA network and qRT-PCR validation, 6 core lncRNAs were selected and considered high correlated with G. lucidum treatment. Bioinformatics analysis revealed FR036820 and FR121302 might act as enhancers, and qRT-PCR results suggested FR121302 might enhance Popdc2 mRNA level in HCC. Furthermore, 6 main triterpene monomers of G. lucidum were identified by UPLC-MS method, and in vitro experiments showed FR121302 and Popdc2 were significantly suppressed by Ganoderenic acid A and Ganoderenic acid B, respectively. The knock/overexpression results demonstrated that FR121302 activating and enhancing Popdc2 expression levels, and Ganoderenic acid A and Ganoderenic acid B dramatically suppressed FR121302 and decreased Popdc2 level in Hepa1-6 cells. CONCLUSIONS Enhancer-associated lncRNA plays a crucial role as an enhancer during hepatocarcinogenesis, and triterpenes of G. lucidum significantly inhibited tumor cell proliferation and induced apoptosis by regulating en-lncRNAs. Our study demonstrated Ganoderenic acid A and Ganoderenic acid B suppressed en-lncRNA FR121302 may be one of the critical strategies of G. lucidum inhibit hepatocellular carcinoma growth.

Abstract
The development and manufacture of high-quality starch are a new research focus in food science. Here, transglutaminase was used in the wet processing of glutinous rice flour to prepare customized sweet dumplings. Transglutaminase (0.2 %) lowered protein loss in wet processing and reduced the crystallinity and viscosity of glutinous rice flour. Moreover, it lowered the cracking and cooking loss of sweet dumplings after freeze-thaw cycles, and produced sweet dumplings with reduced hardness and viscosity, making them more suitable for people with swallowing difficulties. Additionally, in sweet dumplings with 0.2 % transglutaminase, the encapsulation of starch granules by the protein slowed down the digestion and reduced the final hydrolysis rate, which are beneficial for people with weight and glycemic control issues. In conclusion, this study contributes to the production of tasty, customized sweet dumplings.

Abstract
This study comprehensively investigated the effects of high-temperature cooking (HT), complex enzyme hydrolysis (CE), and high-temperature cooking combined enzymatic hydrolysis (HE) on the chemical composition, microstructure, and functional attributes of soluble dietary fiber (SDF) extracted from corn bran. The results demonstrated that HE-SDF yielded the highest output at 13.80 ± 0.20 g/100 g, with enhancements in thermal stability, viscosity, hydration properties, adsorption capacity, and antioxidant activity. Cluster analysis revealed three distinct categories of SDF's physicochemical properties. Principal component analysis (PCA) confirmed the superior functional properties of HE-SDF. Correlation analysis showed positive relationships between the monosaccharide composition, purity, and viscosity of SDF and most of its functional attributes, whereas particle size and zeta potential were inversely correlated. Furthermore, a highly significant positive correlation was observed between crystallinity and thermal properties. These findings suggest that the HE method constitutes a viable strategy for enhancing the quality of SDF sourced from corn bran.

Abstract
Background Metabolic dysfunction-associated fatty liver disease has been linked to negative outcomes in patients with end-stage liver disease following liver transplantation. However, the influence of immunosuppressive regimens on it has not been explored. Methods A retrospective analysis was conducted using the preoperative and postoperative data from patients with end-stage liver disease. The study compared three different groups: tacrolimus-based group, sirolimus-based group, and combined tacrolimus- and sirolimus-based regimens. Binary logistic regression analysis was employed to identify risk factors for metabolic dysfunction-associated fatty liver disease. Results A total of 171 patients participated in the study, consisting of 127 males and 44 females, with a mean age of 49.6 years. The prevalence of posttransplant metabolic dysfunction-associated fatty liver disease was 29.23%. Among the three groups, there were 111 liver transplant recipients in the tacrolimus-based group, 28 in the sirolimus-based group, and 32 in the combination group. A statistically significant difference was observed in the incidence of metabolic dysfunction-associated fatty liver disease (P < 0.05), whereas the other preoperative and postoperative parameters showed no significant differences. Multivariate analysis revealed that a low-calorie diet (95% confidence intervals: 0.15-0.90, P = 0.021) and a combination of tacrolimus- and sirolimus-based immunosuppressive regimen (95% confidence intervals: 1.01-2.77, P = 0.046) were associated with lower risk of posttransplant metabolic dysfunction-associated fatty liver disease. Conclusions Our study indicates that implementing a low-calorie diet and utilizing a combination of tacrolimus- and sirolimus-based immunosuppressive regimen can effectively lower the risk of posttransplant metabolic dysfunction-associated fatty liver disease following liver transplantation.

Abstract
Directly administering medication to inflamed intestinal sites for treating ulcerative colitis (UC), poses significant challenges like retention time, absorption variability, side effects, drug stability, and non-specific delivery. Recent advancements in therapy to treat colitis aim to improve local drug availability that is enema therapy at the site of inflammation, thereby reducing systemic adverse effects. Nevertheless, a key limitation lies in enemas' inability to sustain medication in the colon due to rapid peristaltic movement, diarrhea, and poor local adherence. Therefore, in this work, we have developed site-specific thiolated mucoadhesive anionic nanoliposomes to overcome the limitations of conventional enema therapy. The thiolated delivery system allows prolonged residence of the delivery system at the inflamed site in the colon, confirmed by the adhesion potential of thiolated nanoliposomes using in-vitro and in-vivo models. To further provide therapeutic efficacy thiolated nanoliposomes were loaded with gallic acid (GA), a natural compound known for its antibacterial, antioxidant, and potent anti-inflammatory properties. Consequently, Gallic Acid-loaded Thiolated 2,6 DALP DMPG (GATh@APDL) demonstrates the potential for targeted adhesion to the inflamed colon, facilitated by their small size 100 nm and anionic nature. Therapeutic studies indicate that this formulation offers protective effects by mitigating colonic inflammation, downregulating the expression of NF-κB, HIF-1α, and MMP-9, and demonstrating superior efficacy compared to the free GA enema. The encapsulated GA inhibits the NF-κB expression, leading to enhanced expression of MUC2 protein, thereby promoting mucosal healing in the colon. Furthermore, GATh@APDL effectively reduces neutrophil infiltration and regulates immune cell quantification in colonic lamina propria. Our findings suggest that GATh@APDL holds promise for alleviating UC and addressing the limitations of conventional enema therapy.

Abstract
Short- and medium-chain fatty acids (SMCFA) are monocarboxylic acids with a carbon chain length of 1-12 carbon atoms. They are mainly produced in humans by the gut microbiota, play crucial metabolic roles, are vital for intestinal health, and have multifaceted impact on immune and neurological functions. Accurate detection and quantification of SMCFA in different human biofluids is achieved using 3-nitro phenylhydrazine (3-NPH) derivatization of the free fatty acids followed by reverse phase liquid chromatography (RPLC) separation and detection by tandem mass spectrometry (MS/MS). Here, we describe the simultaneous measurement of 14 SMCFA and lactate in detail. All 3-NPH-SMCFA-hydrazones are separated in less than 5 min with an 8-min total run time (injection-to-injection). Linear dynamic range over 0.1-500 μM is achieved for most SCFAs, while it is 0.05-100 μM for MCFAs. Validation of the procedure depicts good linearity (R2 > 0.98) and repeatability (CV ≤ 20%). The lower limit of detection (LLOD) is 10-30 nM. The lower limit of quantification (LLOQ) is 50-100 nM for most analytes, while it is 0.5 μM for acetate. In conclusion, the method offers several benefits compared to alternative methods regarding throughput, selectivity, sensitivity, and robustness.

Abstract
Immunotherapy, led by programmed cell death protein-1 (PD-1) inhibitors, has emerged as a prominent antitumor therapy, yet prognostic challenges persist in pancreatic cancer (PC). This retrospective, single-center study evaluated prognostic factors in advanced PC patients treated with PD-1 inhibitors at the PLA General Hospital's Oncology Department from 2015-2022. With ethics approval by the Ethics Committee of the General Hospital of the People's Liberation Army (S2021-228-03), we analyzed 126 patients using Kaplan-Meier and Cox models. p < .05 was considered a statistically significant difference. Median overall survival (mOS) and progression-free survival (mPFS) were 12.1 and 4.6 months, respectively. Significant mOS predictors were surgery history (44.2 months vs. 10 months, *p = .022), absence of liver metastases (44.2 months vs. 6.4 months, *p = .034), and baseline CA19-9 ≤ 216.15 U/ml (18.5 months vs. 9.2 months, *p = .049). For mPFS, histologic differentiation (5.5 months vs. 3.2 months, *p = .022) and first-line PD-1 inhibitor use (5.1 months vs. 1.5 months, ***p = .001) were key. Subgroup analyses highlighted early progression in low histologic differentiation and earlier death without surgery. History of surgery, absence of liver metastases, baseline CA19-9 level, and histologic intermediate/high differentiation may predict PD-1 inhibitor efficacy in advanced PC, pending validation in prospective trials.

Abstract
This study aims to analyze Coronavirus Disease 2019 (COVID-19)-associated copper-death genes using the Gene Expression Omnibus (GEO) dataset and machine learning, exploring their immune microenvironment correlation and underlying mechanisms. Utilizing GEO, we analyzed the GSE217948 dataset with control samples. Differential expression analysis identified 16 differentially expressed copper-death genes, and Cell type Identification By Estimating Relative Subsets Of RNA Transcripts (CIBERSORT) quantified immune cell infiltration. Gene classification yielded two copper-death clusters, with Weighted Gene Co-expression Network Analysis (WGCNA) identifying key module genes. Machine learning models (random forest, Support Vector Machine (SVM), Generalized Linear Model (GLM), eXtreme Gradient Boosting (XGBoost)) selected 6 feature genes validated by the GSE213313 dataset. Ferredoxin 1 (FDX1) emerged as the top gene, corroborated by Area Under the Curve (AUC) analysis. Gene Set Enrichment Analysis (GSEA) and Gene Set Variation Analysis (GSVA) revealed enriched pathways in T cell receptor, natural killer cytotoxicity, and Peroxisome Proliferator-Activated Receptor (PPAR). We uncovered differentially expressed copper-death genes and immune infiltration differences, notably CD8 T cells and M0 macrophages. Clustering identified modules with potential implications for COVID-19. Machine learning models effectively predicted COVID-19 risk, with FDX1's pivotal role validated. FDX1's high expression was associated with immune pathways, suggesting its role in COVID-19 pathogenesis. This comprehensive approach elucidated COVID-19-related copper-death genes, their immune context, and risk prediction potential. FDX1's connection to immune pathways offers insights into COVID-19 mechanisms and therapy.

Abstract
Clostridium difficile (Clostridioides difficile) is a leading cause of nosocomial infections in hospitalized patients worldwide. Stool samples were collected from 112 inpatients admitted to different hospitals and were screened for C. difficile GDH + toxin A + B by immunoassay, and all positive samples by immunoassay were processed for molecular detection of C. difficile using the GeneXpert assay. C. difficile strains were detected in 12 (10.71%) out of 112 stool samples using the GDH + toxin A + B immunoassay method and toxigenic C. difficile was confirmed in 5 stool samples using the GeneXpert molecular assay. C. difficile strains were also detected in 7 (8.97%) out of 78 stool samples from intensive care unit patients, 3 (25%) out of 12 stool samples from internal medicine ward patients, 1 (11.11%) out of 9 stool samples from surgery ward patients, and 1 (10%) out of 10 stool samples from isolation ward patients using the GDH + toxin A + B immunoassay method and the toxigenic C. difficile strain was confirmed in 1, 2, 1, and 1 stool samples, respectively, using the GeneXpert molecular assay. Toxigenic C. difficile was confirmed in patients at 4 (51.14%) out of 7 hospitals. In the present study, we also analyzed the clinical information of patients with C. difficile-positive stool samples who were receiving one or more antibiotics during hospitalization. The binary toxin gene (cdt), the tcdC gene, and the C. difficile strain polymerase chain reaction (PCR) ribotype 027 were not detected using the GeneXpert molecular assay among 12 C. difficile-positive samples by immunoassay. This study should aid in the prevention of unnecessary empiric therapy and increase the understanding of the toxigenic C. difficile burden on the healthcare system in the southwestern province of Saudi Arabia.

Abstract
Efficacy of cancer immunotherapies relies on correct recognition of tumor antigens by lymphocytes, eliciting thus functional responses capable of eliminating tumor cells. Therefore, important efforts have been carried out in antigen identification, with the aim of understanding mechanisms of response to immunotherapy and to design safer and more efficient strategies. In addition to classical tumor-associated antigens identified during the last decades, implementation of next-generation sequencing methodologies is enabling the identification of neoantigens (neoAgs) arising from mutations, leading to the development of new neoAg-directed therapies. Moreover, there are numerous non-classical tumor antigens originated from other sources and identified by new methodologies. Here, we review the relevance of neoAgs in different immunotherapies and the results obtained by applying neoAg-based strategies. In addition, the different types of non-classical tumor antigens and the best approaches for their identification are described. This will help to increase the spectrum of targetable molecules useful in cancer immunotherapies.

Abstract
Post-reperfusion syndrome (PRS) is a severe and highly lethal syndrome that occurs after declamping the portal vein forceps during liver transplantation. It is marked by severe hemodynamic disturbances manifested by decreased mean arterial pressure, increased heart rate and elevated pulmonary artery pressure. The complex pathogenesis of PRS remains understudied. It is generally believed to be related to the large amount of acidic, cold blood that enters the circulation after release of the portal clamp. This blood is rich in oxygen-free radicals and metabolic toxins, which not only aggravate the ischemia-reperfusion injury of the liver but also further attack the systemic organs indiscriminately. Considering the range of possible adverse prognoses including acute kidney injury, delirium and graft nonfunction, it is imperative that clinicians increase their awareness and prevention of PRS. The aim of this article is to review the current risk factors, pathophysiological mechanisms and prevention strategies for PRS.

Abstract
BACKGROUND The prognosis for advanced intrahepatic cholangiocarcinoma (iCCA) is poor, and there remains an urgent need to develop efficient systemic therapy. The efficacy of Pembrolizumab immunotherapy combined with lenvatinibin in iCCA is still unclear. The role of Epstein-Barr-virus (EBV) as a biomarker in iCCA for response to immunotherapy needs further exploration. CASE PRESENTATION We report a case of a 60-year-old female with EBV-associated advanced iCCA (EBVaiCCA) who progressed after first-line therapy. She accomplished an available response to the combination therapy of pembrolizumab with lenvatinib, with overall survival of 20 months. CONCLUSIONS As far as we know, this is the first case report about the application of Pembrolizumab with lenvatinib for EBVaiCCA patients. This case indicates that the combination of immunotherapy and antiangiogenic therapy provides a glimmer of hope for advanced EBVaiCCA patients.

Abstract
Varicella vaccine was first licensed in Japan and South Korea in 1989 for use in healthy children and was introduced in US in 1995. So far, 29 countries have adopted varicella vaccine in their universal immunization program (UIP). No Asian country, India included, has adopted the varicella vaccine as part of their UIP. The extra-cutaneous sites for VZV diseases are central nervous system and gastrointestinal tract, the expanded disease spectrum includes vasculopathy, myelitis, inflammatory bowel disease, perforated ulcers, and gastritis. The actual disease burden of varicella is not known as most of the infected individuals may not visit the physician. The amplifiable VZV DNA will not always be detectable in cerebrospinal fluid (CSF) samples in protracted illnesses such as vasculopathies, but demonstrable anti-VZV IgG in CSF has diagnostic value. The World Health Organization (WHO) position paper 2014 recommends two doses of varicella and zoster vaccines in targeted population. In India, varicella vaccine is not included in the UIP due to the cost and the belief that lifelong immunity occurs following primary infection. The expanded spectrum of VZV disease and the mounting body of evidence, however, suggest the need for both varicella and zoster vaccines in routine immunization schedule.

Abstract
Fusobacterium nucleatum, an anaerobic Gram-negative bacterium primarily residing in the oral cavity, has garnered significant attention for its emerging role in cancer progression and prognosis. While extensive research has revealed mechanistic links between Fusobacterium nucleatum and colorectal cancer, a comprehensive review spanning its presence and metastatic implications in cancers beyond colorectal origin is conspicuously absent. This paper broadens our perspective from colorectal cancer to various malignancies associated with Fusobacterium nucleatum, including oral, pancreatic, esophageal, breast, and gastric cancers. Our central focus is to unravel the mechanisms governing Fusobacterium nucleatum colonization, initiation, and promotion of metastasis across diverse cancer types. Additionally, we explore Fusobacterium nucleatum's adverse impacts on cancer therapies, particularly within the domains of immunotherapy and chemotherapy. Furthermore, this paper underscores the clinical research significance of Fusobacterium nucleatum as a potential tumor biomarker and therapeutic target, offering a novel outlook on its applicability in cancer detection and prognostic assessment.

A survey into the utilization of probiotics and medicinal plants among individuals afflicted with gastrointestinal disorders in healthcare institutions in Saïda, Algeria. Libyan J Med 2024; 19:2317492. [PMID: 38369815 PMCID: PMC10878339 DOI: 10.1080/19932820.2024.2317492] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2024] [Accepted: 02/07/2024] [Indexed: 02/20/2024] Open
Abstract
Aim: Functional gastrointestinal (GI) disorders are recognized as a major public health concern worldwide. These disorders involve persistent digestive symptoms indicative of digestive tract dysfunction.Materials and Methods: A survey examining the utilisation of probiotics and medicinal plants as supplementary treatments was conducted on 160 patients with GI disorders at healthcare institutions in Saïda from March to April 2023 using questionnaires that had been previously adapted and tested for reliability with Cronbach's alpha test. Raw data collected through the questionnaires were transferred to a database and analysed using SPSS software.Results: Overall, 49.38% of participants possessed knowledge of or actively utilised probiotics; such awareness was strongly associated with the participants' educational attainment (p = 0.029). The noteworthy probiotic supplements were Biocharbon (36.09%), Lactocil (15.38%), Smebiocta (13.61%), Ultrabiotic Adult (12.43%), Effidigest (12.43%), and Ultralevure (7.69%). During crisis, individuals tended to consume natural goods rich in probiotics, including yoghurt (13.26%) and fermented milk (8.60%), as well as foods rich in prebiotic fibre, including vegetables (18.99%), fruits (13.26%), wheat (9.67%), bran (7.52%), rye (6.81%), and oat flakes (6.45%). Additionally, 77.56% of patients used medicinal plants during crises, with Mentha spicata (12.2%), Thymus vulgaris (11.3%), Pimpinella anisum (8.5%), Cuminum cyminum (8.0%), Punica granatum (7.8%), Trachyspermum ammi (7.5%), and Senna acutifolia (7.0%) being the more commonly favoured options in phytotherapy. The main focus of these herbs was to alleviate bloating (57%), constipation (30.12%), and diarrhoea (12.87%) (p < 0.001). The most frequently utilised plant parts were leaves (47.30%), seeds (25.21%), and bark (13.21%). Most patients (82.91%) favoured infusion as their preferred consumption method, and approximately 85.43% believed in phytotherapy's ability to extend symptomatic relief.Conclusion: The understanding of probiotics is still in its infancy, whereas phytotherapy is more widely accepted by patients. Nonetheless, patients are open to the exploration of natural alternatives to conventional medicines.

Abstract
Metastasis accounts for the vast majority of cancer deaths; however, this complex process has yet to be fully explained. To form metastases, cancer cells must undergo a series of steps, known as the "Metastatic cascade", each of which requires a specific functional transformation. Cancer stem cells (CSCs) play a vital role in tumor metastasis, but their dynamic behavior and regulatory mechanisms have not been fully elucidated. Based on the "Metastatic cascade" theory, this review summarizes the effect of liver CSCs on the metastatic biological programs that underlie the dissemination and metastatic growth of cancer cells. Liver CSCs have the capacity to initiate distant organ metastasis via EMT, and the microenvironment transformation that supports the ability of these cells to disseminate, evade immune surveillance, dormancy, and regenerate metastasis. Understanding the heterogeneity and traits of liver CSCs in these processes is critical for developing strategies to prevent and treat metastasis of advanced hepatocellular carcinoma (HCC).

Abstract
Immunotherapy has recently attracted considerable attention. However, currently, a thorough analysis of the trends associated with the epithelial-mesenchymal transition (EMT) and immunotherapy is lacking. In this study, we used bibliometric tools to provide a comprehensive overview of the progress in EMT-immunotherapy research. A total of 1,302 articles related to EMT and immunotherapy were retrieved from the Web of Science Core Collection (WOSCC). The analysis indicated that in terms of the volume of research, China was the most productive country (49.07%, 639), followed by the United States (16.89%, 220) and Italy (3.6%, 47). The United States was the most influential country according to the frequency of citations and citation burstiness. The results also suggested that Frontiers in Immunotherapy can be considered as the most influential journal with respect to the number of articles and impact factors. "Immune infiltration," "bioinformatics analysis," "traditional Chinese medicine," "gene signature," and "ferroptosis" were found to be emerging keywords in EMT-immunotherapy research. These findings point to potential new directions that can deepen our understanding of the mechanisms underlying the combined effects of immunotherapy and EMT and help develop strategies for improving immunotherapy.

Abstract
Whole-genome sequencing was used to identify a dominant inherited NLRP12 c.1382dup mutation in refractory familial Crohn's disease (CD) patients. Additionally, we observed a T insertion at position 1382 in the third exon of NLRP12, leading to a frameshift mutation. Isolation of peripheral blood from mutation carriers and subsequent experiments demonstrated increased interleukin (IL)-1β in CD patients with the NLRP12 c.1382dup mutation. However, the mechanisms by which the NLRP12 c.1382dup mutation mediates IL-1β remain unclear. Our research findings reveal a close correlation between elevated p-ERK levels and increased expression of NLRP3 and IL-1β in the presence of the NLRP12 c.1382dup mutation. Further experiments demonstrate that inhibiting p-ERK with PD98059 effectively reduces the production of NLRP3 and IL-1β. This discovery provides new insights into the pathogenesis of CD, highlighting the significant role of the ERK/NLRP3/IL-1β pathway in the progression of CD. Not only does this offer novel therapeutic targets for treating CD, but it also lays the groundwork for the development of treatment strategies targeting this pathway.

NOD1 and NOD2 genetic variants: Impact on hepatocellular carcinoma susceptibility and progression in Moroccan population. Gene 2024; 931:148847. [PMID: 39147112 DOI: 10.1016/j.gene.2024.148847] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2024] [Revised: 07/25/2024] [Accepted: 08/12/2024] [Indexed: 08/17/2024]
Abstract
BACKGROUND Nucleotide-binding oligomerization domain 1 (NOD1) and NOD2 are involved in carcinogenic processes by recognizing bacterial cell wall components and triggering inflammation. This study explored the association between genetic variations in NOD1 and NOD2 and susceptibility to hepatocellular carcinoma (HCC) and its progression in a Moroccan population. METHODS Genotyping of NOD1 rs2075820 (C>T) and NOD2 rs718226 (A>G) was performed using the TaqMan allelic discrimination assay in 467 Moroccan individuals. The cohort included 156 patients with hepatocellular carcinoma (HCC), 155 patients with liver cirrhosis (LC) diagnosed with HBV, HCV, or MASLD, and 156 controls. RESULTS The NOD1 rs2075820 variant showed no association with HCC susceptibility or progression, which is consistent with in silico predictions. However, the NOD2 rs718226 G allele and GG genotype were more common in the HCC group compared to the cirrhosis and control groups. Individuals with the homozygous G variant had a 2-fold higher risk for HCC (ORad = 2.12; CI=1.01-4.44; Pad = 0.04). Those with the GG genotype also had an increased risk of HCC (GG vs. AG+AA ORad = 2.28; CI=1.15-4.54; Pad = 0.016). Furthermore, GG genotype carriers had a significantly higher risk of HCC progression (ORad = 2.58; CI=1.26-5.31; Pad = 0.031). Individuals with the rs718226 minor allele had a significantly elevated risk of progressing from LC to HCC (ORad = 1.50; CI=1.07-2.09; Pad = 0.016). Stratification analysis indicated that men had a higher risk of HCC progression compared to women (ORad = 4.63; CI=1.53-14.00 vs. ORad = 2.73; CI=1.05-7.09). CONCLUSION The NOD1 rs2075820 polymorphism does not appear to be a genetic risk factor for susceptibility to HCC. In contrast, the non-coding NOD2 rs718226 variant significantly increases HCC susceptibility and promotes liver cancer progression in the Moroccan population. Further studies involving larger cohorts are warranted to definitively confirm or refute the effects of NOD1 and NOD2 genetic variants on liver cancer susceptibility and progression.

Abstract
BACKGROUND Crohn's disease (CD) is marked by disruption of intestinal epithelial barrier, with unclear underlying molecular mechanisms. This study aimed to investigate key genes regulating the intestinal barrier in CD patients. METHODS Differential gene expression analysis and gene set enrichment analysis were conducted to identify potential key genes involved in CD within the GEO database. Single-cell RNA sequencing from ileum samples in GSE134809 of 59,831 inflamed and uninflamed cells from 11 CD patients and microarray data from ileal tissues in GSE69762 (3 controls and 4 CD patients) and GSE75214 (11 controls and 51 CD patients) with GSE179285 (49 uninflamed and 33 inflamed from CD patients) as the validation set. Protein-protein interaction and logistic regression analyses identified key downregulated genes in CD. A key gene was then investigated through immunohistochemistry of ileal tissues from 5 CD patients and in the Caco-2 cell line with RNA interference and treatment with IFN-γ and TNF-α to stimulate inflammation. RESULTS Single-cell RNA-seq identified 33 genes and microarray identified 167 genes with significant downregulation in inflamed CD samples. PCK1 was identified and validated as one of the most promising candidate genes. Reduced PCK1 expression was evident in inflamed ileal tissues. In vitro, knockdown of PCK1 resulted in decreased cell viability, increased apoptosis, and reduced nectin-2 production, while combination of IFN-γ and TNF-α significantly reduced PCK1. CONCLUSIONS PCK1 is downregulated in inflamed ileal tissues of CD patients and may be a key factor in maintaining epithelial integrity during inflammation in Crohn's disease.

Abstract
BACKGROUND While prior data showed an increasing incidence of hepatocellular carcinoma (HCC) in the United States, there are limited comprehensive and comparative data on the geographical variations of HCC trends in different demographic-specific populations.
AIM To evaluate sex and age-specific incidence rates and time trends in different geographical regions in the United States.
METHODS Age-adjusted HCC incidence rates were collected from the United States Cancer Statistics (USCS) database which covers approximately 98% of the population in the United States. HCC rates were stratified by sex, age, and geographical region. annual percentage change (APC) and average APC (AAPC) were estimated using Joinpoint Regression. A pairwise comparison was conducted between sex-specific trends.
RESULTS There were 467344 patients diagnosed with HCC in the United States in the USCS database between 2001 and 2020. The rates and trends varied by geographical region. When looking at the West region (115336 patients), incidence rates of HCC were overall increasing and also increasing in older adults. However, when evaluating younger adults, HCC incidence rates decreased in men but not in women with a sex-specific absolute AAPC-difference of 2.15 (P = 0.005). When evaluating the Midwest region (84612 patients), similar results were seen. While incidence rates were increasing in the overall population and in older adults as well, they were decreasing in younger men but not in women with a sex-specific absolute AAPC-difference of 1.61 (P < 0.001). For the Northeast region (87259 patients), the analysis showed similar results with decreasing HCC incidence rates in younger men but not counterpart women (Sex-specific AAPC-difference = 3.26, P < 0.001). Lastly, when evaluating the south (180137 patients), the results were also decreasing in younger men but not in women (Sex-specific AAPC-difference = 2.55, P < 0.001).
CONCLUSION Nationwide analysis covering around 98% of the United States population shows an increasing incidence of HCC across all geographical regions, most notably in the South. While younger men experienced decreasing HCC incidence, younger women had a stable trend and this was noted across all regions as well. Our study offers insight into the epidemiology of HCC in different demographic groups across various United States geographical regions. While the reasons contributing to our findings are unclear, they can be related to sex and regional disparities in healthcare access and utilization. Future research is warranted to characterize the temporal change in HCC risk factors across different United States regions.

Abstract
BACKGROUND Prostaglandin E1 (PGE1), or alprostadil, is a potent vasodilator that improves hepatic blood flow and reduces ischemia-reperfusion injury post-liver transplantation (LT). However, the benefits of PGE1 on renal function after LT have not yet been well described.
AIM To assess the impact of PGE1 administration on renal function in patients who underwent liver or liver-kidney transplant.
METHODS This retrospective study included all patients who underwent liver or liver-kidney transplant at our institution from January, 2011 to December, 2021. Patients were classified based on whether they received PGE1. PGE1 was administered post-LT to those with transaminases > 1000 U/L in the immediate postoperative period. Demographics, post-LT treatments and/or complications, renal function, and survival were analyzed. Multivariable logistic regression analysis was performed, and a two-tailed P value < 0.05 was considered statistically significant.
RESULTS A total of 145 patients underwent LT, with 44 (30%) receiving PGE1. Baseline patient characteristics were comparable, except the PGE1 group had significantly higher aspartate aminotransferase (AST) (1961.9 U/L ± 1862.3 U/L vs 878 U/L ± 741.4 U/L, P = 0.000), alanine aminotransferase (1070.6 U/L ± 895 U/L vs 547.7 U/L ± 410 U/L, P = 0.000), international normalized ratio on post-LT day 1 (2 ± 0.74 vs 1.8 ± 0.4, P = 0.03), a longer intensive care unit stay (8.1 days ± 11.8 days vs 3.8 days ± 4.6 days, P = 0.003), more vasopressor use (55.53 hours ± 111 hours vs 16.33 hours ± 26.3 hours, P = 0.002), and higher immediate postoperative complications (18.6% vs 4.9%, P = 0.04). The PGE1 group also had a significantly higher 90-day readmission rate (29.6% vs 13.1%, P = 0.02) and lower 1-year liver graft survival (87.5% vs 98.9%, P = 0.005). However, 30-day readmission (31.6% vs 27.4%, P = 0.64), LT complications (hepatic artery thrombosis, biliary complications, rejection of liver graft, cardiomyopathy), 1-year patient survival (96.9% vs 97.8%, P = 0.77), overall liver graft survival, and overall patient survival were similar between the two groups (95.4% vs 93.9%, P = 0.74 and 88.4% vs 86.9%, P = 0.81 respectively). Although the PGE1 group had a significantly lower glomerular filtration rate (eGFR) on post-LT day 7 (46.3 mL/minute ± 26.7 mL/minute vs 62.5 mL/minute ± 34 mL/minute, P = 0.009), the eventual need for renal replacement therapy (13.6% vs 5.9%, P = 0.09), the number of dialysis sessions (0.91 vs 0.27, P = 0.13), and eGFR at 1-month (37.2 mL/minute ± 35.9 mL/minute vs 42 mL/minute ± 36.9 mL/minute, P = 0.49), 6-months (54.8 mL/minute ± 21.6 mL/minute vs 62 mL/minute ± 21.4 mL/minute, P = 0.09), and 12-months (63.7 mL/minute ± 20.7 mL/minute vs 62.8 mL/minute ± 20.3 mL/minute, P = 0.85) post-LT were similar to those in the non-PGE1 group.
CONCLUSION In patients who received PGE1 for ischemia-reperfusion injury, despite immediate acute renal injury post-LT, the renal function at 1-month, 6-months, and 12-months post-LT was similar compared to those without ischemia-reperfusion injury. Prospective clinical trials are needed to further elucidate the benefits of PGE1 use in renal function.

Abstract
Bioactive components from Porphyra tenera (PT) have been reported to confer various health benefits. The role of PT in inflammatory bowel disease (IBD) has not been fully investigated. This study aimed to explore the anti-inflammatory properties of PT on dextran sodium sulfate (DSS)-treated mice. PT supplementation attenuated the severity of colitis in DSS-treated mice, evidenced by the reduction of disease activity index (DAI), restoration of colonic histological damage and suppression of abnormal inflammatory response. Sequencing analysis indicated that intake of PT alleviated DSS-induced gut microbiota dysbiosis, accompanied by reversing the generation of short-chain fatty acids (SCFAs) and bile acids (BAs). Overall, our findings demonstrated that supplementation of PT attenuated the severity of intestinal inflammation and ameliorated gut microbiota dysbiosis in a murine colitis model, which provided a rationale for further application of edible seaweeds for preventing inflammation-related disorders in humans.

Abstract
Lentinan (LNT), a natural polysaccharide, has been reported to exhibit immunomodulatory effects in the intestine after oral administration. Herein, we aimed to investigate the lymphatic transport of LNT in Peyer's patches (PPs) by traceable fluorescent labeling and to explore whether/how LNT contacts related immune cells. Near-infrared imaging confirmed the absorption of LNT in the small intestinal segment and its accumulation within PPs after oral administration. Subsequently, tissue imaging confirmed that M cells are the main cells responsible for transporting LNT to PPs, and an M cell model was established to explore the involvement of Dectin-1 in the absorption process. Systematic in vitro and in vivo studies revealed that the Dectin-1 further mediates the uptake of LNT by mononuclear phagocytes in PPs. Moreover, LNT can promote the proliferation and differentiation of mononuclear phagocytes, thereby activating immune responses. In summary, this study elucidates the pharmacokinetic mechanisms by which LNT exerts oral immunomodulatory effects, providing a theoretical basis for the development and application of other polysaccharides.

Abstract
The bioactivity of polysaccharide was closely related to its fermentation utilization by gut Bacteroides, and its utilization degree was determined by various gut Bacteroides species and different polysaccharides characteristics. The effects of longan polysaccharide (LP) and LP treated by ultrasonic-assisted hydrogen peroxide for 8 h (DLP-8) on gut Bacteroides growth, and their fermentation utilization were compared. The results of LP and DLP-8 on the proliferation of six Bacteroides species showed that Bacteroides uniformis had the highest proliferation index. In fermentation by B. uniformis, DLP-8 (with a lower molecular weight), the viable count of which was higher than that of LP, was degraded more and especially utilized more glucose and glucuronic acid. The microstructure of the two polysaccharides changed differently during fermentation. Moreover, DLP-8 promoted greater short-chain fatty acids production than LP. These results indicated that the fermentation properties of DLP-8 by B. uniformis were superior to those of LP.

Abstract
Recently we have investigated polysaccharide from Imperata cylindrica (ICP) for its physicochemical structure and biological activities. However, the digestion characteristics have yet to be understood. This study investigated the digestion and metabolism characteristics of ICP through in vivo fluorescence tracking, in vitro simulated digestion, fecal fermentation experiments, and microbial sequencing. The results showed that ICP significant distribution in the gastrointestinal tract and kidneys. ICP underwent slight degradation during simulated gastric and intestinal digestion. During fecal fermentation, the utilization degree of ICP and the concentration of short-chain fatty acids (SCFAs) increased. ICP promoted the increase of beneficial microbial abundance. To understand the impact of ICP on the integrity and health of intestinal tissues, molecular docking was employed to preliminarily predict the interaction between ICP and key proteins. The results revealed that ICP could recognize and bind to key proteins through high-affinity targeting binding sites.

Structure-anti-inflammatory activity relationship of garlic fructans in mice with dextran sulfate sodium-induced colitis: Impact of chain length. Carbohydr Polym 2024; 346:122582.

Abstract
The present study identified the protective effects of garlic oligo/poly-saccharides of different chain lengths against dextran sulfate sodium (DSS)-induced colitis in mice and elucidated the structure-function relationships. The results showed that oral intake of garlic oligo/poly-saccharides decreased disease activity index, reduced colon shortening and spleen enlargement, and ameliorated pathological damage in the mouse colon. The dysregulation of colonic pro/anti-inflammatory cytokines was significantly alleviated, accompanied by up-regulated antioxidant enzymes, blocked TLR4-MyD88-NF-κB signaling pathway, enhanced intestinal barrier integrity, and restored SCFA production. Garlic oligo/poly-saccharides also reversed gut microbiota dysbiosis in colitic mice by expanding beneficial bacteria and suppressing the growth of harmful bacteria. High-molecular-weight polysaccharides exhibited stronger alleviating effects on DSS-induced colitic symptoms in mice than low-molecular-weight oligo/poly-saccharides did, probably due to their greater ability to be fermented in the colon. Taken together, this study demonstrated the anti-inflammatory effects of garlic oligo/poly-saccharides and revealed that high-molecular-weight polysaccharide fractions were more effective in alleviating DSS-induced colitis.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease and represents the main cause of liver cirrhosis and hepatocellular carcinoma. Cav3.2 is a T-type calcium channel that is widely present in tissues throughout the body and plays a vital role in energy and metabolic balance. However, the effects of Cav3.2 on the NFALD remain unclear. Here, we investigated the role of Cav3.2 channel in the development and progression of NAFLD. After 16 weeks on a high-fat diets (HFD), Cav3.2 knockout (Cav3.2 KO) improved hepatic steatosis, liver injury and metabolic syndrome in an NAFLD mouse model. We provided evidence that Cav3.2 KO inhibited HFD-induced hepatic oxidative stress, inflammation and hepatocyte apoptosis. In addition, Cav3.2 KO also attenuated hepatic lipid accumulation, oxidative stress, inflammation and hepatocyte apoptosis in palmitic acid/oleic acid (PAOA)-treated primary hepatocytes. These results suggest that therapeutic approaches targeting Cav3.2 provide effective approaches for treating NAFLD.

Abstract
Therapeutic antibodies (Ab) have revolutionized the management of multiple illnesses including respiratory tract infections (RTIs). However, anti-infectious Ab displayed several limitations including antigen restrictiveness, narrowed therapeutic windows, and limited dose in the vicinity of the target when delivered by parenteral routes. Strategies enhancing further Ab-dependent containment of infection are currently needed. Here we showed that a combination of inhaled anti-infectious Ab and probiotics is an efficient formulation to protect against lung infection. Using a mouse model of Pseudomonas aeruginosa-induced pneumonia, we demonstrated a synergistic effect reducing both bacterial burden and pro-inflammatory response affording protection against primary and secondary infections. This is the first study showing that the local combination in the airways of anti-infective Ab and probiotics subverts suboptimal potency of Ab monotherapy and provides protection against respiratory pathogen.

JOURNAL OF ETHNOPHARMACOLOGY 2024; 335:118690. [PMID: 39142621 DOI: 10.1016/j.jep.2024.118690] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/09/2024] [Revised: 07/22/2024] [Accepted: 08/09/2024] [Indexed: 08/16/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Postmenopausal osteoporosis (PMOP) has been considered as a major causative factor for bone-joint pain and inducing pathologic fractures. Bu-Sui-Dan (BSD), a classic ancient herbal formula, has been shown to exhibit osteoprotective effects by promoting bone marrow development and bone growth. However, the exact mechanism of BSD are still unexplored. AIM OF STUDY The study aimed to investigate the protective effect of BSD against osteoporotic injury, and to explore whether BSD regulated BMSCs' osteogenic differentiation by targeting VGLL4, which in turn improved PMOP. MATERIALS AND METHODS The anti-osteoporotic effect of BSD was studied in ovariectomized (OVX) rats and bone marrow mesenchymal stem cells (BMSCs). Micro-CT imaging and HE staining were performed, and the levels of osteogenic protein RUNX2 and osteogenesis-related factor VGLL4 were determined. Co-immunoprecipitation (Co-IP) was further employed to delve into the effects of BSD on the interactions between TEAD4 and RUNX2. The key osteogenic factors 1ALP, COLl1A1, and Osterix expression were detected by RT-qPCR. Co-IP and proximity ligation assay (PLA) were employed to scrutinize the influence of BSD on TEAD4 and RUNX2 inter-binding. Moreover, VGLL4 knockdown in BMSCs was conducted to confirm the role of VGLL4 in the therapeutic mechanism of BSD. RESULTS BSD showed a dose-dependent protective effect against osteoporotic injury, as evidenced by improvement in bone volume, bone microarchitecture, and histomorphometry. Additionally, BSD treatment increased the levels of RUNX2 and its downstream target genes including ALP, COL1A1, and Osterix. Moreover, BSD upregulated VGLL4 expression and lessened TEAD4-RUNX2 interactions. In BMSCs experiment, BSD-containing serum could promote osteogenic differentiation of BMSCs, boosted the expression of osteogenesis-related factors and VGLL4 level. The knockdown of VGLL4 in BMSCs diminished the promotion effect of BSD in osteoblast differentiation, suggesting that VGLL4 play a vital role in the therapeutic effects exerted by BSD. CONCLUSION BSD ameliorated osteoporosis injury and promoted osteoblast differentiation through upregulation of VGLL4 levels, which in turn antagonized TEAD4-mediated RUNX2 transcriptional repression. Our study implied that BSD may be an osteoporosis therapeutic agent.

JOURNAL OF ETHNOPHARMACOLOGY 2024; 335:118628. [PMID: 39053717 DOI: 10.1016/j.jep.2024.118628] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/08/2024] [Revised: 07/21/2024] [Accepted: 07/22/2024] [Indexed: 07/27/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Peucedanum praeruptorum Dunn (PPD) was used to treat gastrointestinal disease in China before the Tang Dynasty, and it was considered a "Top-grade" herb in Shennong Bencaojing, known for its ability to relieve the stomach Qi and indigestion. AIM OF THE STUDY Alcohol consumption can induce severe gastric mucosal injury that lacks effective and safe interventions. We aimed to investigate the gastroprotective effects of Peucedanum praeruptorum Dunn leaf (PPL) after bolting in alcohol-induced gastric damage in mice. MATERIALS AND METHODS Mice were orally administered PPL aqueous extract at doses of 2.5, 5, and 10 g/kg for 5 consecutive days prior to the induction of gastric damage model with ethanol. Gastric tissue was stained by hematoxylin and eosin (H&E), and the levels of pro-inflammatory cytokines and oxidative stress indicators were determined using ELISA and RT-qPCR. RNA-seq was used to detect differentially expressed genes (DEGs) in the gastric tissue, while Western blotting was employed to measure the expressions of IL-17, TNF-a, and AKT pathways. RESULTS Treatment with PPL alleviated alcohol-induced gastric damage in mice, whereas dried root (PPD) and stem (PPS) of Peucedanum praeruptorum Dunn had no gastroprotective function. The content of peucedanocoumarin I was higher in the dried PPL compared to PPD and PPS, with an increase in peucedanocoumarin I content in PPL after boiling. Additionally, PPL administration (5, 10 g/kg) decreased pro-inflammatory factors, such as interleukin-6 (IL-6), IL-8, IL-4, IL-1β, IL-18, and tumor necrosis factor (TNF-a) in alcohol-induced gastric injury mice (p < 0.05), and improved oxidative stress markers, including superoxide dismutase enzymes (SOD), catalase (CAT), and malondialdehyde (MDA) (p < 0.05). RNA-seq data revealed that PPL treatment inhibited alcohol-induced inflammation-related signals, including IL-17 and TNF pathways, and restored alcohol-inhibited gastric digestive and metabolic functions, such as xenobiotics metabolism of cytochrome P450, and protein digestion and absorption pathways. Notably, treatment with PPL downregulated the expressions of IL-17 A, TNF-a, monocyte chemoattractant protein-1 (MCP-1), and AKT-phosphorylation induced by ethanol exposure (p < 0.05). Thus, the aqueous extract of PPL provided protection against alcohol-induced gastric injury by mitigating inflammation and oxidative stress in mice, suggesting a potential novel therapeutic approach for alcohol-induced gastric damage.

JOURNAL OF ETHNOPHARMACOLOGY 2024; 335:118646.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ligustrum lucidum W.T. Aiton is a traditional Chinese medicine that has long been used with high hepatoprotective therapeutic and condition value. Specnuezhenide (SP), the standard prominent secoiridoid compound of Fructus Ligustri Lucidi may ameliorate hepatic inflammation in chronic liver diseases. AIM OF THE STUDY Regulating inflammation through SIRT6-P2X7R axis has caused the emergence of novel molecular mechanism strategies for reversing hepatic fibrosis. This study focused on the mechanism of SP in modulating the liver inflammatory microenvironment in hepatic fibrosis. MATERIALS AND METHODS C57BL/6 mice with hepatic fibrosis were stimulated with thioacetamide (TAA) prior to administration of SP. Hepatic stellate cells (HSCs) or normal mouse primary hepatocytes were exposed to transforming growth factor-β (TGF-β) treatment. Meanwhile, normal mouse bone marrow-derived macrophages (BMDMs) were treated with lipopolysaccharide/adenosine triphosphate (LPS/ATP), aiming to obtain the conditioned medium. HSCs and hepatocytes were transfected with SIRT6 knockdown vector (siRNA-SIRT6) to estimate the impact of SP on the SIRT6-P2X7R/NLRP3 signaling pathway. RESULTS SP suppressed the HSCs extracellular matrix (ECM) deposition as well as pro-inflammatory cytokine levels induced by the medium of BMDMs or TGF-β. In addition, SP also significantly up-regulated SIRT6, inhibited P2X7R-NLRP3 inflammasome in HSCs and hepatocytes, and functioned as MDL-800 (a SIRT6 agonist). SP reduced the hepatocytes pyroptosis and further prevented the occurrence of inflammatory response in the liver. SP could inhibit the activation of BMDMs and impede IL-1β and IL-18 from entering extracellular regions. Moreover, deficiency of SIRT6 in HSCs or hepatocytes reduced SP's regulation of P2X7R suppression. For TAA-treated mice, SP mitigated histopathological changes, ECM accumulation, EMT process, and NETs formation in hepatic fibrosis. CONCLUSIONS Therefore, SP decreased inflammatory response via SIRT6-P2X7R/NLRP3 pathway and suppressed fibrillogenesis. These findings supported SP as the novel candidate to treat hepatic fibrosis.

Abstract
OBJECTIVE This study aims to explore the caregiver burden experience in the care of infants with congenital megacolon undergoing home reflux enema. The findings will provide a basis for developing targeted and effective nursing interventions. METHODS A phenomenological research approach was employed. From October 2022 to January 2023, semi-structured in-depth interviews were conducted with 12 caregivers of infants with congenital megacolon undergoing home reflux enema in a tertiary paediatric hospital in Fujian Province. The collected data were analysed and organized using the Colaizzi's 7-step analysis method, leading to the identification of key themes. RESULTS The analysis yielded three major themes concerning the caregiver burden experience in the care of infants with congenital megacolon undergoing home reflux enema: inadequate disease-related knowledge, presence of multiple pressures during the caregiving process, and a desire for greater support. CONCLUSIONS This study employed qualitative interviews with the caregivers of 12 children with congenital Hirschsprung's disease undergoing home reflux enema, and the feelings of caregivers of children with reflux enema at home after discharge were deeply understood. It is recommended to implement positive psychological interventions based on the PERMA model and incorporate "Internet + collaborative nursing" to provide caregivers with professional knowledge, address their pressures and needs, and promote their well-being while enhancing nursing abilities.

Abstract
BACKGROUND The chemotherapy resistance often leads to chemotherapy failure. This study aims to explore the molecular mechanism by which MUC1 regulates paclitaxel resistance in lung adenocarcinoma (LUAD), providing scientific basis for future target selection. METHODS The bioinformatics method was used to analyse the mRNA and protein expression characteristics of MUC1 in LUAD. RT-qPCR and ELISA were used to detect the mRNA and protein expression, flow cytometry was used to detect CD133+ cells, and cell viability was detected by CCK-8 assay. The mRNA-seq was performed to analyse the changes in expression profile, GO and KEGG analysis were used to explore the potential biological functions. RESULTS MUC1 is highly expressed in LUAD patients and is associated with a higher tumour infiltration. In paclitaxel resistance LUAD cells (A549/TAX cells), the expression of MUC1, EGFR/p-EGFR and IL-6 were higher than that of A549 cells, the proportion of CD133+ cells was significantly increased, and the expression of cancer stem cell (CSCs) transcription factors (NANOG, OCT4 and SOX2) were significantly up-regulated. After knocking down MUC1 in A549/Tax cells, the activity of A549/Tax cells was significantly decreased. Correspondingly, the expression of EGFR, IL-6, OCT4, NANOG, and SOX2 were significantly down-regulated. The mRNA-seq showed that knocking down MUC1 affected the gene expression, DEGs mainly enriched in NF-κB and MAPK signalling pathway. CONCLUSION MUC1 was highly expressed in A549/TAX cells, and MUC1-EGFR crosstalk with IL-6 may be due to the activation of NF-κB and MAPK pathways, which promote the enrichment of CSCs and lead to paclitaxel resistance.

Quantifying fecal and plasma short-chain fatty acids in healthy Thai individuals. Comput Struct Biotechnol J 2024; 23:2163-2172.

Abstract
Short-chain fatty acids (SCFAs) are involved in important physiological processes such as gut health and immune response, and changes in SCFA levels can be indicative of disease. Despite the importance of SCFAs in human health and disease, reference values for fecal and plasma SCFA concentrations in healthy individuals are scarce. To address this gap in current knowledge, we developed a simple and reliable derivatization-free GC-TOFMS method for quantifying fecal and plasma SCFAs in healthy individuals. We targeted six linear- and seven branched-SCFAs, obtaining method recoveries of 73-88% and 83-134% in fecal and plasma matrices, respectively. The developed methods are simpler, faster, and more sensitive than previously published methods and are well suited for large-scale studies. Analysis of samples from 157 medically confirmed healthy individuals showed that the total SCFAs in the feces and plasma were 34.1 ± 15.3 µmol/g and 60.0 ± 45.9 µM, respectively. In fecal samples, acetic acid (Ace), propionic acid (Pro), and butanoic acid (But) were all significant, collectively accounting for 89% of the total SCFAs, whereas the only major SCFA in plasma samples was Ace, constituting of 93% of the total plasma SCFAs. There were no statistically significant differences in the total fecal and plasma SCFA concentrations between sexes or among age groups. The data revealed, however, a positive correlation for several nutrients, such as carbohydrate, fat, iron from vegetables, and water, to most of the targeted SCFAs. This is the first large-scale study to report SCFA reference intervals in the plasma and feces of healthy individuals, and thereby delivers valuable data for microbiome, metabolomics, and biomarker research.

Abstract
Metabolic disease is a worldwide epidemic that has become a public health problem. Gut microbiota is considered to be one of the important factors that maintain human health by regulating host metabolism. As an abundant bacterium in the host gut, A. muciniphila regulates metabolic and immune functions, and protects gut health. Multiple studies have indicated that alterations in the abundance of A. muciniphila are associated with various diseases, including intestinal inflammatory diseases, obesity, type 2 diabetes mellitus, and even parasitic diseases. Beneficial effects were observed not only in live A. muciniphila, but also in pasteurized A. muciniphila, A. muciniphila-derived extracellular vesicles, outer membrane, and secreted proteins. Although numerous studies have only proven the simple correlation between multiple diseases and A. muciniphila, an increasing number of studies in animal models and preclinical models have demonstrated that the beneficial impacts shifted from correlations to in-depth mechanisms. In this review, we provide a comprehensive view of the beneficial effects of A. muciniphila on different diseases and summarize the potential mechanisms of action of A. muciniphila in the treatment of diseases. We provide a comprehensive understanding of A. muciniphila for improving host health and discuss the perspectives of A. muciniphila in the future studies.

Abstract
BACKGROUND Ulcerative colitis (UC) is a disease characterized by chronic relapsing-remitting inflammatory disorders and is associated with environmental changes. AIM To explore the disease patterns of Chinese UC patients and to determine controllable related environmental factors. METHODS This multicentre cross-sectional study was performed using a questionnaire survey. Data on clinical characteristics and environmental factors were collected. Patients with a disease course ≥5 years were defined as the long course group, and those with a disease course < 5 years were defined as the short course group. RESULTS A total of 588 effective questionnaires were collected. The proportion of the chronic continuous pattern was the highest among patients with a long disease course (46.8%), and in patients with a short disease course, the proportion of the active to remission pattern was the highest (53.3%). In patients with a long disease course, a higher proportion of patients with adequate sleep was found in the active to remission pattern than in the chronic intermittent (72.1% vs. 43.3%, p = 0.008) and chronic continuous (72.1% vs. 52.4%, p = 0.016) patterns. In patients with a short disease course, the frequency of shellfish and shrimp was higher in the chronic continuous pattern group than in the active to remission pattern group (P = 0.001 and 0.017 respectively). CONCLUSIONS For early diagnosis patients, dietary guidance should be actively carried out. With the prolongation of the disease course, attention should be given to the sleep quality of patients.
