Abstract
An excessive inflammatory response of the gastrointestinal tract is recognized as one of the major contributors to ulcerative colitis (UC). Despite this, effective preventive approaches for UC remain limited. Rosmarinic acid (RA), an enriched fraction from Perilla frutescens, has been shown to exert beneficial effects on disease-related inflammatory disorders. However, RA-enriched perilla seed meal (RAPSM) and perilla seed (RAPS) extracts have not been investigated in dextran sulfate sodium (DSS)-induced UC in mice. RAPSM and RAPS were extracted using the solvent-partitioning method and analyzed with high-pressure liquid chromatography (HPLC). Mice with UC induced using 2.5% DSS for 7 days were pretreated with RAPSM and RAPS (50, 250, 500 mg/kg). Then, the clinical manifestation, colonic histopathology, and serum proinflammatory cytokines were determined. Indeed, DSS-induced UC mice exhibited colonic pathological defects including an impaired colon structure, colon length shortening, and increased serum proinflammatory cytokines. However, RAPSM and RAPS had a protective effect at all doses by attenuating colonic pathology in DSS-induced UC mice, potentially through the suppression of proinflammatory cytokines. Concentrations of 50 mg/kg of RAPSM and RAPS were sufficient to achieve a beneficial effect in UC mice. This suggests that RAPSM and RAPS have a preventive effect against DSS-induced UC, potentially through alleviating inflammatory responses and relieving severe inflammation in the colon.

Abstract
OBJECTIVE Ulcerative colitis (UC), a chronic and refractory nonspecific inflammatory bowel disease, affects millions of patients worldwide and increases the risk of colorectal cancer. Teprenone is an acylic polyisoprenoid that exerts anti-inflammatory properties in rat models of peptic ulcer disease. This in vitro and in vivo study was designed to investigate the effects of teprenone on UC and to explore the underlying mechanisms. METHODS Human intestinal epithelial cells (Caco-2 cells) serve as the in vitro experimental model. Lipopolysaccharide (LPS, 1 μg/mL) was employed to stimulate the production of pro-inflammatory cytokines (interleukin [IL]-6, IL-1β, and tumor necrosis factor [TNF]-α), Toll-like receptor-4 (TLR4), MyD88 expression, and NF-κB activation. A trinitrobenzene sulfonic acid (TNBS)-induced chronic UC rat model was employed for the in vivo assay. RESULTS Pro-inflammatory cytokine stimulation by LPS in Caco-2 cells was inhibited by teprenone at 40 μg/mL through the TLR4/NF-κB signaling pathway. Teprenone attenuated TNBS-induced UC, decreased myeloperoxidase and malondialdehyde, induced TLR4 expression and NF-κB activation, and increased glutathione and zonula occludens-1 level in the rat colonic tissue. Moreover, Fusobacterium, Escherichia coli, Porphyromonas gingivalis elevation, and Mogibacterium timidum decline in UC rats were inhibited by teprenone. CONCLUSION Based on our results, the protective effects of teprenone for UC may be related to its ability to modulate the gut microbiota and reduce the inflammatory response.

Abstract
BACKGROUND AND AIM Although diet is one of the potential environmental factors affecting ulcerative colitis (UC), evidence is not sufficient to draw definitive conclusions. This Japanese case-control study examined the association between the consumption of coffee, other caffeine-containing beverages and food, and total caffeine and the risk of UC. METHODS The study involved 384 UC cases and 665 control subjects. Intake of coffee, decaffeinated coffee, black tea, green tea, oolong tea, carbonated soft drinks, and chocolate snacks was measured with a semiquantitative food-frequency questionnaire. Adjustments were made for sex, age, pack-years of smoking, alcohol consumption, history of appendicitis, family history of UC, education level, body mass index, and intake of vitamin C, retinol, and total energy. RESULTS Higher consumption of coffee and carbonated soft drinks was associated with a reduced risk of UC with a significant dose-response relationship (P for trend for coffee and carbonated soft drinks were <0.0001 and 0.01, respectively), whereas higher consumption of chocolate snacks was significantly associated with an increased risk of UC. No association was observed between consumption of decaffeinated coffee, black tea, green tea, or oolong tea and the risk of UC. Total caffeine intake was inversely associated with the risk of UC; the adjusted odds ratio between extreme quartiles was 0.44 (95% confidence interval: 0.29-0.67; P for trend <0.0001). CONCLUSIONS We confirmed that intake of coffee and caffeine is also associated with a reduced risk of UC in Japan where people consume relatively low quantities of coffee compared with Western countries.

Abstract
Ulcerative colitis is an inflammatory bowel disease with a complex aetiology characterised by abnormal immune responses and oxidative stress-induced tissue injury. Inflammatory cells play an important role in the progression of this pathology through the overproduction of reactive oxygen species (ROS) from various sources including the NADPH oxidases (NOXs). The aim of this study was to investigate the preventive effect of apocynin, a natural antioxidant molecule and a selective inhibitor of NOXs, on acetic acid (AA)-induced ulcerative colitis in rats. Our results first confirmed that apocynin has a high free radical scavenging capacity as well as a potent iron chelating ability. Oral pretreatment of rats with apocynin (200 mg/kg and 400 mg/kg) for 7 days prior to AA-induced colitis suppressed the increase in pro-oxidant markers in colonic homogenates and preserved colonic cytoarchitecture from acetic acid-induced damage. Oral administration of apocynin (200 mg/kg and 400 mg/kg) also reduced several systemic inflammatory markers such as alkaline phosphatase, iron, pro-inflammatory cytokines, C-reactive protein and myeloperoxidase. This study shows that apocynin protects rats from acetic acid-induced colonic inflammation and suggests that apocynin may have a promising beneficial effect in the prevention of ulcerative colitis.

Abstract
Background and Objectives: Urtica dioica, a source of bioactive functional compounds, provides nutritional and gastrointestinal therapeutic benefits. This study attempted to investigate the prophylactic coloprotective action of an aqueous extract of Urtica dioica (AEUD) on dextran sulfate sodium (DSS)-induced ulcerative colitis (UC). Materials and Methods: Phenolic compounds, total sugar, and mineral levels were determined in AEUD. Then, AEUD at different doses (50, 100, and 200 mg/kg, BW, p.o.) and mesalazine (MESA) as a standard treatment (100 mg/kg, BW, p.o.) were given orally for 21 days. Acute colitis was induced by administering drinking water with 5% (w/v) DSS for 7 days. Body weight variation, fecal occult blood, and stool consistency were determined daily. The severity of colitis was graded according to colon length, disease activity index (DAI), histological evaluations, and biochemical alterations. Rats orally administered DSS regularly developed clinical and macroscopic signs of colitis. Results: Due to its richness in phenolic and flavonoid compounds (247.65 ± 2.69 mg EAG/g MS and 34.08 ± 0.53 mg EQt/g MS, respectively), AEUD markedly ameliorated DAI, ulcer scores, colon length shortening, colonic histopathological changes, and hematological and biochemical modifications. Taken together, AEUD treatment notably (p < 0.01) suppressed DSS-induced UC by reducing oxidative stress via lowering MDA/H2O2 production and stimulating the effect of enzyme antioxidants as well as attenuating inflammation by decreasing CRP levels by 79.5% between the DSS and DSS + AEUD-50 groups compared to the MESA group (75.6%). Conclusions: AEUD was sufficient to exert a coloprotective effect that might be influenced by its bioactive compounds' anti-inflammatory and antioxidant capabilities.

Abstract
Ulcerative colitis (UC) is a non-specific inflammatory bowel illness characterized by intestinal mucosal barrier degradation, inflammation, oxidative damage, and gut microbiota imbalances. Rosa roxburghii Tratt Fruit extract (RRTE) was extracted from Rosa roxburghii Tratt fruit, exhibiting an excellent prevention effect against UC; RRTE could prevent the damage of DSS-induced human normal colonic epithelial (NCM 460) cells, especially in cell viability and morphology, and oxidative damage. Additionally, in UC mice, RRTE could limit the intestinal mucosal barrier by increasing the expression of intestinal tight junction proteins and mucin, reducing inflammation and oxidative damage in colon tissue. More importantly, RRTE can increase the abundance of beneficial bacteria to regulate gut microbiota such as Ruminococcus, Turicibacter, and Parabacteroides, and reduce the abundance of harmful bacteria such as Staphylococcus and Shigella. Furthermore, transcriptomics of colonic mucosal findings point out that the beneficial effect of RRTE on UC could be attributed to the modulation of inflammatory responses such as the IL-17 and TNF signaling pathways. The qPCR results confirm that RRTE did involve the regulation of several genes in the IL-17 signaling pathway. In conclusion, RRTE could prevent DSS-induced damage both in vitro and in vivo.

Abstract
Ulcerative colitis (UC) is a chronic and recurrent inflammatory disease with an unknown pathogenesis and increasing incidence. The objective of this study is to investigate the impact of prophylactic treatment with Cordyceps militaris on UC. The findings demonstrate that prophylactic supplementation of C. militaris powder effectively mitigates disease symptoms in DSS-injured mice, while also reducing the secretion of pro-inflammatory cytokines. Furthermore, C. militaris powder enhances the integrity of the intestinal mucosal barrier by up-regulating MUC2 protein expression and improving tight junction proteins (ZO-1, occludin, and claudin 1) in DSS-injured mice. Multiomics integration analyses revealed that C. militaris powder not only reshaped gut microbiota composition, with an increase in Lactobacillus, Odoribacter, and Mucispirillum, but also exerted regulatory effects on various metabolic pathways including amino acid, glyoxylates, dicarboxylates, glycerophospholipids, and arachidonic acid. Subsequent analysis further elucidated the intricate interplay of gut microbiota, the intestinal mucosal barrier, and metabolites, suggesting that the microbiota-metabolite axis may involve the effect of C. militaris on intestinal mucosal barrier repair in UC. Moreover, in vitro experiments demonstrated that peptides and polysaccharides, derived from C. militaris, exerted an ability to change the gut microbiota structure of UC patients' feces, particularly by promoting the growth of Lactobacillus. These findings suggest that regulatory properties of C. militaris on gut microbiota may underlie the potential mechanism responsible for the protective effect of C. militaris in UC. Consequently, our study will provide support for the utilization of C. militaris as a whole food-based ingredient against the occurrence and development of UC.

Abstract
BACKGROUND Limited prospective studies that have examined the association of dietary fibre with IBD have provided inconsistent evidence. AIM To examine any associations between dietary fibre intake and subsequent incidence of IBD, Crohn's disease (CD) and ulcerative colitis (UC) METHODS: We conducted a prospective cohort study of 470,669 participants from the UK Biobank and estimated dietary fibre intake from a valid food frequency questionnaire at baseline. Incident IBD was ascertained from primary care data and inpatient data. Cox proportional hazard models were used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) for associations between dietary fibre intake and the risk of IBD, CD and UC. RESULTS During an average follow-up of 12.1 years, we ascertained 1473 incident IBD cases, including 543 cases of CD and 939 cases of UC. Comparing the lowest quintiles, an inverse association was observed between dietary fibre intake and risk of IBD (HR 0.74, 95% CI 0.58-0.93, p = 0.011) and CD (HR 0.48, 95% CI 0.32-0.72, p < 0.001), but not UC (HR 0.92, 95% CI 0.69-1.24, p = 0.595). For specified sources, dietary fibre intake from fruit and bread decreased the risk of CD, while dietary fibre intake from cereal decreased the risk of UC. CONCLUSIONS Higher consumption of dietary fibre was associated with a lower risk of IBD and CD, but not UC. Our findings support current recommendations to increase the intake of dietary fibre.

Abstract
BACKGROUND Tilapia skin collagen hydrolysates (TSCHs) are the product of enzymatic hydrolysis of collagen, which is mainly extracted from tilapia skin. The components of TSCHs have recently been reported to play a preventive role in dextran sulfate sodium (DSS)-induced ulcerative colitis (UC). However, it has not been illustrated whether TSCHs can prevent against DSS-induced UC via the gut microbiota and its derived metabolites. RESULTS TSCHs are mainly composed of amino acids, which have similar characteristics to collagen, with most having a molecular weight below 5 kDa. In a mouse model of UC, TSCHs had no toxic effect at a dose of 60 g kg-1 and could reduce body weight changes, colon length, histopathological changes and score, and the level of the serum inflammatory cytokine interleukin (IL)-6. Concurrently, 16 S rRNA sequencing showed that TSCHs significantly reduced the abundance of Bacteroidetes and Proteobacteria at the phylum level and norank_f__Muribaculaceae and Escherichia-Shigella at the genus level, while they increased the abundance of Firmicutes at the phylum level and Lachnoclostridium, Allobaculum, Enterorhabdus, and unclassified__f__Ruminococcaceae at the genus level. Target metabolomic analysis showed that TSCHs elevated the concentration of total acid, acetic acid, propanoic acid, and butanoic acid, but reduced isovaleric acid concentrations. Moreover, Pearson correlation analysis revealed that Allobaculum, unclassified_Ruminococcaceae, and Enterorhabdus were positively correlated with acetic acid and butyric acid, but not Escherichia-Shigella. CONCLUSION These findings suggest that TSCHs can prevent UC by modulating gut microbial and microbiota-derived metabolites. © 2023 Society of Chemical Industry.

Abstract
κ-Selenocarrageenan (KSC) is an organic selenium (Se) polysaccharide. There has been no report of an enzyme that can degrade κ-selenocarrageenan to κ-selenocarrageenan oligosaccharides (KSCOs). This study explored an enzyme, κ-selenocarrageenase (SeCar), from deep-sea bacteria and produced heterologously in Escherichia coli, which degraded KSC to KSCOs. Chemical and spectroscopic analyses demonstrated that purified KSCOs in hydrolysates were composed mainly of selenium-galactobiose. Organic selenium foods through dietary supplementation could help regulate inflammatory bowel diseases (IBD). This study discussed the effects of KSCOs on dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) in C57BL/6 mice. The results showed that KSCOs alleviated the symptoms of UC and suppressed colonic inflammation by reducing the activity of myeloperoxidase (MPO) and regulating the unbalanced secretion of inflammatory cytokines (tumor necrosis factor (TNF)-α, interleukin (IL)-6 and IL-10). Furthermore, KSCOs treatment regulated the composition of gut microbiota, enriched the genera Bifidobacterium, Lachnospiraceae_NK4A136_group and Ruminococcus and inhibited Dubosiella, Turicibacter and Romboutsia. These findings proved that KSCOs obtained by enzymatic degradation could be utilized to prevent or treat UC.

Abstract
Ulcerative colitis has been consistently associated with gut microbiota imbalance and disturbed immune system. Emerging research suggests a protective function of polyphenols on prevention and treatment of ulcerative colitis, yet underlying mechanisms remain unclear. Fu brick tea, a postfermented tea, contains abundant polyphenols with anti-inflammatory and antioxidant properties. In the present study, we found that prophylactic supplementation of polyphenols extracted from Fu brick tea (FBTP) dose-dependently alleviated colitis symptoms, immune cells infiltration, and pro-inflammatory cytokines secretion in mice suffering dextran sulfate sodium induced murine colitis. FBTP substantially reshaped gut microbiota and promoted microbial transformation of tryptophan into indole-3-acetic acid (I3A), thereafter leading to aryl hydrocarbon receptor (AHR)-mediated protection from colitis through enhanced expressions of IL-22 and tight junction proteins (i.e., ZO-1, occluding and claudin-1) in colon. Multiomics integration analyses revealed strong connections between I3A, tryptophan-metabolizing bacteria, AHR activity, and pathological phenotypes of colitis. Notably, FBTP failed to significantly alleviate colitis symptoms in the absence of gut microbiota, while intragastric administration of I3A could imitate benefits of FBTP on colitis alleviation and intestinal epithelial homeostasis through a direct enhancement in AHR activity in microbiota-depleted mice. These findings further determine the key role of gut microbiota controlled I3A-AHR signaling in mediating the FBTP on colitis alleviation. This study provides the first data proposing the FBTP as a natural prebiotic for colitis alleviation through the gut microbiota-dependent modulation of the AHR pathway. Most importantly, we also identified I3A as a key microbial metabolite targeted by FBTP for exhibiting health-promoting effects.

Abstract
CONTEXT Ulcerative colitis (UC) is a chronic idiopathic inflammatory bowel disease that is closely related to inflammation and apoptosis. The traditional Chinese medicine compound preparation Huangqin decoction (HQD) has been widely used in the clinical treatment of UC, but the specific mechanism of its function is still inconclusive. OBJECTIVE To explore the pathogenesis of UC based on the IFN-γ/JAK/ETS signalling pathway, and to clarify the biological mechanism of HQD. MATERIALS AND METHODS Forty 8-week-old male C57BL/6 mice were randomly divided into four groups: normal control, model, model + salazosulfapyridine group (500 mg/kg, p.o., pd) and model + HQD (9.1 g/kg, p.o., pd). Using Dextran sulphate sodium (DSS) salt (2.5%, p.o.)+high-fat diet + hot and humid environment to build a mouse model of UC. One month later, the changes of colon morphology, serum inflammatory factors, intestinal epithelial cell apoptosis and IFN-γ/JAK/ETS signalling pathway related protein changes in mice were observed. RESULTS Compared with the model group, HQD significantly reduced the pathological score of the model mice's colon (2.60 ± 0.25 vs. 4.80 ± 0.37), and reduced the serum IFN-γ (200.30 ± 8.45 vs. 413.80 ± 6.97) and other inflammatory factors, and reduced intestinal epithelial cell apoptosis (24.85 ± 4.87 vs. 214.90 ± 39.21). In terms of mechanism, HQD down-regulated IFN-γ/JAK/ETS signalling pathway related proteins in colon tissue of UC model mice. CONCLUSIONS These data indicate that HQD can improve UC by reducing intestinal inflammation and apoptosis, providing experimental evidence for the wide application of HQD in clinical practice of UC.

Abstract
BACKGROUND Previous studies reported that Aloe vera ameliorated DSS-induced colitis and promoted mucus secretion. However, the effect of Aloin A (AA), a major compound of Aloe vera, on colitis and its exact mechanism remains uncovered. METHODS C57BL/6 mice were successively subjected to 3% DSS solution for 5 days and distilled water for 2 days. Concurrently, AA (25, 50 mg/kg) and 5-aminosalicylic (500 mg/kg) were administrated intragastrically from day 1 to day 7. Colitis was evaluated by disease active index (DAI), colon length, inflammation response, and intestinal barrier function. In vitro LS174T cells challenged with 50 ng/ml of lipopolysaccharides (LPS) were used to validate the modulatory action of AA on the Notch signaling pathway. RESULTS Our results showed that oral administration with AA prominently prevented DSS-induced colitis symptoms in terms of decreased DAI, prevention of colon shortening, and reduced pathological damage. AA mitigated the inflammatory response evidenced by the decreased proinflammatory cytokines (TNF-α, IL-1β, IL-6) and increased anti-inflammatory cytokine (IL-10). Besides, AA inhibited apoptosis and facilitated proliferation in colons. Moreover, AA treatment up-regulated the expression of tight junction (TJ) proteins (ZO-1, Occludin) and promoted the secretion of MUC2 to decrease colon permeability. Mechanistically, AA inhibited the Notch pathway to promote the secretion of MUC2, which was consistent with LPS-challenged LS174 cells. CONCLUSION These results suggested that AA could prevent colitis by enhancing the intestinal barrier function via suppressing the Notch signaling pathway. Thus, AA might be a prospective remedy for ulcerative colitis.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Atractylodes lancea (Thunb.) DC. is traditionally used as a folk medicine for treating gastrointestinal diseases in China. Nevertheless, the effect and mechanisms of its anti-inflammatory activity on dextran sodium sulfate (DSS)-induced ulcerative colitis (UC) have not yet been fully investigated. AIM OF THE STUDY This study aimed to explore the therapeutic effect and underlying molecular mechanisms of Ethanolic Extract of Atractylodis Rhizoma (EEAR) on DSS-induced UC mice and LPS-induced RAW264.7 cells. MATERIALS AND METHODS The EEAR was obtained and then analyzed by HPLC analysis. The protective effect of EEAR on DSS-induced UC was evaluated by weight loss, disease activity index (DAI) score, spleen index, goblet cell loss, colon length shortening, myeloperoxidase (MPO) activity and pathological changes. The level of inflammatory cytokines were detected by immunohistochemistry (IHC) and RT-PCR analysis. The expressions of the tight junction (TJ, such as ZO-1, Occludin) proteins and the target proteins in mitogen-activated protein kinase (MAPK) and nuclear factor-kappa B (NF-κB) were determined by western blotting analysis. RESULTS EEAR significantly attenuated the symptoms of UC, suppressed the colon MPO activity, and increased the goblet cell loss. In addition, EEAR could significantly increase the expression of TJs in UC mice. Meanwhile, EEAR treatment could reduce the levels of inflammatory cytokines and inhibit the phosphorylation of MAPK and NF-κB signaling pathways in UC mice and in LPS-induced RAW264.7 cells. CONCLUSION Our results indicated that EEAR ameliorated DSS-induced UC by inhibiting the inflammatory response and maintaining the intestinal barrier function via modulation of MAPK/NF-κB pathways, thus, EEAR might be a promising therapeutic candidate for UC therapy.

Abstract
Sweet tea (Lithocarpus litseifolius [Hance] Chun) is a new resource for food raw materials, with plenty of health functions. This study aimed to investigate the preventive effect and potential mechanism of sweet tea extract (STE) against ulcerative colitis (UC). Briefly, BABL/c mice were treated with STE (100 and 400 mg/kg) for 2 weeks to prevent 3% dextran sulfate sodium (DSS)-induced UC. It was found that STE supplementation significantly prevented DSS-induced UC symptoms; suppressed the levels of pro-inflammatory mediators, such as myeloperoxidase and tumor necrosis factor-α; increased the levels of anti-inflammatory cytokines; and up-regulated the expression of tight junction proteins (Zonula occludens-1 and Occludin). STE also altered the gut microbiota profile of UC mice by increasing Bacteroidetes, Lactobacillus, Akkermansia, Lachnospiraceae_NK4A136_group, and Alistipes and inhibiting Firmicutes, Proteobacteria, and Helicobacter, accompanied by a significant increase in the content of butyric acid. Moreover, STE increased the expression of G-protein-coupled receptor (GPR) 43 and GPR109A and inhibited the expression of histone deacetylase 3 (HDAC3) and nuclear factor-κB p65 (NF-κB p65) in the colon. In conclusion, this study indicated that STE has a good preventive effect on UC by regulating gut microbiota to activate butyrate-GPR-mediated anti-inflammatory signaling and simultaneously inhibit HDAC3/NF-κB inflammatory signaling.

Abstract
BACKGROUND Dextran sodium sulfate (DSS)-triggered ulcerative colitis (UC) model in animals provides a valuable platform to preclinically evaluate the outcome of drug candidates for UC. Dandelion root extracts (DRE) have a therapeutic effect on UC. However, the protective mechanism of DRE against UC remains unknown. OBJECTIVES To discover the targeting pathway involved in DRE-induced protection against UC. MATERIAL AND METHODS The UC model was developed in C57BL/6 mice by oral administration of DSS. Following DSS exposure, sulfasalazine (SASP), low dose of DRE (DRE-L), moderate dose of DRE (DRE-M), high dose of DRE (DRE-H), and DRE-H plus mitogen-activated protein kinases (MAPK) agonist (DRE-H+MA) were administered to the mice. Colon Mucosal Damage Index (CMDI) and histopathological analysis were used to evaluate the colonic mucosal damage. The cytokine levels were detected using commercial enzyme-linked immunosorbent assay (ELISA) kits. The MAPK pathway activation was determined with western blotting. RESULTS We found that DRE-H attenuated DSS-triggered colonic mucosal damage. The DSS-induced inflammatory responses and oxidative stress in the bloodstream and colon tissues were dramatically inhibited by DRE-H administration. Also, this plant impaired DSS-provoked phosphorylation levels of extracellular signal-regulated kinases (ERK), c-Jun N-terminal kinases (JNK), p38 mitogen-activated protein kinases (p38), p65, and IκB. More importantly, MAPK agonist, BIM-23A760, removed the protective effect of DRE-H on the bloodstream and colon tissues. CONCLUSIONS The DRE-H is capable of relieving DSS-induced UC, and its mechanism links to the MAPK pathways.

Abstract
BACKGROUND Ulcerative colitis (UC) is a chronic colon inflammation that is linked to exposure to environmental factors leading to improper immune responses to enteric microbes in genetically susceptible individuals. This study was designed to explore the possible protective impact of Empagliflozin (EMPA), an anti-diabetic sodium-glucose cotransporter-2 (SGLT2) inhibitor, on acetic acid (AA)-induced UC in rats. METHOD Intrarectal instillation of AA (2 ml, 3% v/v) was used to induce UC. EMPA (10 & 30 mg/kg) was administered orally for 11 days. RESULTS EMPA successfully counteracted AA-induced UC that was manifested by improving colonic histopathological architecture concomitant with a marked decrease in disease activity index (DAI), colon weight, weight/length ratio, serum lactate dehydrogenase (LDH) activity, and C-reactive protein (CRP) level. Additionally, EMPA successfully restored the disrupted oxidant/antioxidants balance induced by AA. Moreover, EMPA significantly induced silent information regulator-1(SIRT-1) expression along with a significant reduction in phosphatidylinositol-3-Kinase (PI3K), Protein Kinase B (AKT), nuclear factor kappa B (NF-κB), tumor necrosis factor (TNF)-α and interleukins (IL-1β and IL-6) expression in colonic tissues. Furthermore, EMPA successfully improved the colonic barrier that was appeared from the marked induction of tight junction proteins level (occludin and claudin-1). CONCLUSION EMPA successfully counteracted AA-induced UC in rats via the modulation of SIRT1/PI3K/AKT/NF-κB inflammatory pathway, normalizing oxidant/antioxidants balance, and improving the integrity of colon barrier.

Abstract
Lactic acid, a metabolic by-product of host and intestinal microbiota, has been recovered as an active signal molecule in the immune system. In this study, a lactic acid biosynthesis pathway that directly produces lactic acid from glucose rather than ethanol with high production was reconstructed in Saccharomyces cerevisiae. The engineered S. cerevisiae showed anti-inflammatory activity in dextran sulfate sodium (DSS)-induced mice with improved histological damage, increased mucosal barrier, and decreased intestinal immune response. Lactic acid regulated the macrophage polarization state and inhibited the expression of pro-inflammatory cytokines in vivo and in vitro. Increasing the macrophage monocarboxylic acid transporter-mediated active lactic acid uptake suppressed the excessive activation of the NLRP3 inflammasome and the downstream caspase-1 pathway in macrophages. Moreover, lactic acid promoted histone H3K9 acetylation and histone H3K18 lactylation. Meanwhile, the engineered S. cerevisiae altered the diversity and composition of the intestinal microbiota and changed the abundance of metabolic products in mice with colitis. In conclusion, this study shows that the application of engineered S. cerevisiae attenuated DSS-induced colitis in mice via suppressing macrophage pyroptosis and modulating the intestinal microbiota, which is an effective and safe treatment strategy for ulcerative colitis.

Abstract
Previous studies reported that Agrimonia pilosa (AP) Ledeb possessed diverse biological activities, including anti-inflammatory, antioxidant, and anti-tumor activities. However, the effect of AP on ulcerative colitis (UC) remains unclear. In this study, we investigated the therapeutic effect and mechanisms of AP on dextran sodium sulfate (DSS)-induced colitis. The potential constituents of AP were investigated by ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS). A total of 13 compounds were recognized by UPLC-Q-TOF/MS chromatogram. Furthermore, a network pharmacology approach revealed that there are 297 candidate targets of UC and 549 common targets for the 13 active ingredients of AP. GO enrichment and KEGG pathway analysis indicated that AP might have a protective effect on UC through the nuclear factor κB (NF-κB) and nucleotide-binding oligomerization domain (NOD)-like receptor signaling pathways. Subsequent experimental validation in a DSS-induced colitis model revealed that AP alleviated the severity of DSS-induced colitis, reduced the production of proinflammatory factors, and protected against the loss of intestinal integrity. Moreover, AP inhibited the phosphorylation of NF-κB p65 and the activation of the NLRP3 inflammasome. In conclusion, AP ameliorated DSS-induced colitis through suppressing the activation of the NLRP3 inflammasome and NF-κB signaling pathways.

Abstract
BACKGROUND & AIMS The molecular checkpoints driving T cell activation and cytokine responses in ulcerative colitis (UC) are incompletely understood. Here, we studied the Tec kinase ITK in UC. METHODS We analyzed patients with inflammatory bowel disease (n = 223) and evaluated ITK activity as well as the functional effects of cyclosporine-A (CsA). In addition, 3 independent murine colitis models were used to investigate the functional role of ITK. Finally, the activity of ITK was blocked via pharmacological inhibitors and genetically engineered mice. Readout parameters were mini-endoscopy, histopathology, mucosal T cell apoptosis, and cytokine production. RESULTS We found an expansion of pITK-expressing mucosal CD4+ T cells in UC rather than Crohn's disease that correlated with disease severity. CsA suppressed activation of ITK in cultured CD4+ T cells and calcineurin-containing microclusters adjacent to the T cell receptor signaling complex. Functionally, the capacity of CsA to suppress activity of experimental colitis was critically dependent on ITK. Genetic inactivation of Itk via gene targeting or induction of allele-sensitive Itk mutants prevented experimental colitis in 3 colitis models, and treatment with pharmacological ITK blockers suppressed established colitis. In addition, ITK controlled apoptosis and activation of mucosal Th2 and Th17 lymphocytes via NFATc2 signaling pathways. CONCLUSIONS ITK activation was detected in UC and could be down-regulated in cultured T cells by CsA administration. Selective targeting of ITK emerges as an attractive approach for treatment of chronic intestinal inflammation and potentially UC by driving resolution of mucosal inflammation.

Abstract
Ulcerative colitis (UC) is a chronic disease characterized by mucosal and submucosal inflammation, which has a low cure rate and is prone to relapse, due to the immune imbalance of the body. Inhibition of inflammation-related pathways can delay the progression of UC. Toll-like receptor 4 (TLR4) pathway is considered to be one of the important signaling pathways involved in colon inflammation. Eriodictyol (EDT) is a natural flavonoid widely distributed in foodborne plants. EDT plays an important role in the regulation of inflammation and related signaling pathways. However, whether EDT plays a role in UC remains unknown. Herein, we established a TNBS induced animal model of enteritis in Wistar rats. Our data confirmed the establishment of TNBS induced animal model of enteritis and the administration Eriodictyol in Wistar rats. EDT treatment alleviated TNBS-induced intestinal tissue injury in rats. We further found that EDT reduced MPO expression and regulated the cytokine parameters in TNBS-induced intestinal tissues of rats. The levels of TNF-α, IL-1β, IL-6, IL-10, IL-2, and IL-12 were also affected by the treatment of EDT. EDT also affected SOD, CAT, GSH-Px, and MDA level in rats with colitis. Moreover, EDT regulated TNBS-induced TLR4/NF-κB pathway activation, therefore inhibiting the progression of UC. Our results suggest that EDT could be a potential therapeutic agent for UC.

Abstract
The symbiotic relationships shared between humans and their gastrointestinal parasites present opportunities to discover novel therapies for inflammatory diseases. A prime example of this phenomenon is the interaction of humans and roundworms such as the hookworm, Necator americanus. Epidemiological observations, animal studies and clinical trials using experimental human hookworm infection show that hookworms can suppress inflammation in a safe and well-tolerated way, and that the key to their immunomodulatory properties lies within their secreted proteome. Herein we describe the identification of 2 netrin domain-containing proteins from the N. americanus secretome, and explore their potential in treating intestinal inflammation in mouse models of ulcerative colitis. One of these proteins, subsequently named Na-AIP-1, was effective at suppressing disease when administered prophylactically in the acute TNBS-induced model of colitis. This protective effect was validated in the more robust CD4 T cell transfer model of chronic colitis, where prophylactic Na-AIP-1 reduced T-cell-dependent type-1 cytokine responses in the intestine and the associated intestinal pathology. Mechanistic studies revealed that depletion of CD11c+ cells abrogated the protective anticolitic effect of Na-AIP-1. Next generation sequencing of colon tissue in the T-cell transfer model of colitis revealed that Na-AIP-1 induced a transcriptomic profile associated with the downregulation of metabolic and signaling pathways involved in type-1 inflammation, notably TNF. Finally, co-culture of Na-AIP-1 with a human monocyte-derived M1 macrophage cell line resulted in significantly reduced secretion of TNF. Na-AIP-1 is now a candidate for clinical development as a novel therapeutic for the treatment of human inflammatory bowel diseases.

Abstract
Ulcerative colitis (UC) is a refractory chronic colitis disease with the particularly complex cause. Recently, long noncoding RNAs (lncRNAs) have been reported to be related to the development of UC. LncRNA MEG3 has been proved to play an anti-inflammatory role in a variety of inflammatory diseases, which share similar pathogenesis with UC, indicating the potential involvement of lncRNA MEG3 in UC. This study aims to investigate the functional role and underlying mechanism of lncRNA MEG3 in UC. Gradient concentration of H2O2 (0, 20, 50, 100, and 200 μM) was used to induce Caco-2 damage models in vitro. Cell viability was detected by cell counting kit-8 (CCK-8) assay. LncRNA MEG3, miR-98-5p, and IL-10 levels in H2O2-treated Caco-2 cells were assessed by performing real-time quantitative polymerase chain reaction (RT-qPCR). Moreover, the binding relationship between lncRNA MEG3 and miR-98-5p, as well as the binding relationship between miR-98-5p and IL-10, was validated using dual-luciferase reporter assay. 2, 4, 6-Trinitrobenzenesulfonic acid solution (TNBS) was applied to induce ulcerative colitis in young rats. The body weight, disease activity index (DAI), length and weight of the colons, pathological scores of UC rats, reactive oxygen species (ROS), and inflammatory cytokines were determined to evaluate the effects of lncRNA MEG3 on the progression of UC. Besides, hematoxylin-eosin (HE) staining was exploited to observe histological changes of UC rat colons. In addition, western blotting analysis was also performed to evaluate the apoptosis and pyroptosis-related protein levels. Moreover, lncRNA MEG3, miR-98-5p, and IL-10 levels in UC rat colons were further assessed by RT-qPCR. Meanwhile, IL-10 expression was determined using immunohistochemistry. LncRNA MEG3 and IL-10 levels were distinctly decreased while miR-98-5p was increased in Caco-2 damage models and UC rats. Bioinformatics analysis predicted the binding sites of lncRNA MEG3 to miR-98-5p and miR-98-5p to IL-10. Besides, dual-luciferase reporter assay validated the negative correlation between lncRNA MEG3 and miR-98-5p, miR-98-5p, and IL-10. Overexpressed lncRNA MEG3 reduced. DAI scores and colon weight/length ratio improved UC ulceration. In addition, upregulation of lncRNA MEG3 relieved oxidative stress, inflammatory response, apoptosis, and pyroptosis of UC rat colons. LncRNA MEG3 overexpression alleviates the serve ulceration of UC rat colons by upregulating IL-10 expression via sponging miR-98-5p. To sum up, this study reveals the protective role of lncRNA MEG3 in the development of UC and may provide potential therapeutic targets for UC.

Abstract
The purpose of this paper was to explore the therapeutic effect and underlying mechanism of Tremella fuciformis polysaccharides (TFP) on ulcerative colitis (UC) based on dextran sodium sulfate (DSS)-induced mice UC model and lipopolysaccharide (LPS)-stimulated Caco-2 cells model. The results firstly indicated that TFP can significantly alleviate the symptoms and signs of the DSS-induced mice UC model, which manifests as improvement of body weight loss, increase of colon length, decrease of colon thickness and reduction of intestinal permeability. Then, results from histopathological and electron microscope analysis further implied that TFP could dramatically reduce inflammatory cells infiltration and restore intestinal epithelial barrier integrity. In addition, the experiments of LPS-stimulated Caco-2 cells model in vitro also further confirmed that TFP could markedly inhibit the expressions of pro-inflammatory cytokines and increase related genes or proteins expressions of intestinal barrier and mucus barrier. Taken together, these data suggested that TFP has a significant therapeutic effect on DSS-induced UC model, and its mechanisms are closely linked to the inhibition of inflammation and the restoration of intestinal barrier and mucus barrier function. These beneficial effects may make TFP a promising drug to be used in alleviating UC.

Abstract
Ulcerative colitis (UC) is a chronic and relapsing inflammatory bowel disorder in the colon and rectum leading to low life-quality and high societal costs. Ursolic acid (UA) is a natural product with pharmacological and biological activities. The studies are aimed at investigating the protective and treatment effects of UA against the dextran sulfate sodium- (DSS-) induced UC mouse model and its underlying mechanism. UA was orally administered at different time points before and after the DSS-induced model. Mice body weight, colon length, and histological analysis were used to evaluate colon tissue damage and therapeutic evaluation. Intestinal transcriptome and microbe 16 s sequencing was used to analyze the mechanisms of UA in the prevention and treatment of UC. The early prevention effect of UA could effectively delay mouse weight loss and colon length shorten. UA alleviated UC inflammation and lowered serum and colon IL-6 levels. Three classical inflammatory pathways: MAPKs, IL-6/STAT3, and PI3K were downregulated by UA treatment. The proportion of macrophages and neutrophils in inflammatory cell infiltration was reduced in UA treatment groups. UA could significantly reduce the richness of intestinal flora to avoid the inflammatory response due to the destruction of the intestinal epithelial barrier. The function of UA against UC was through reducing intestinal flora abundance and regulating inflammatory and fatty acid metabolism signaling pathways to affect immune cell infiltration and cytokine expression.

Abstract
Ulcerative colitis (UC) is a chronic inflammatory bowel disease that causes long-lasting inflammation and colitis in the gastrointestinal tract. Depression is a common symptom in patients with UC. (R)-ketamine is a new safer antidepressant than (R,S)-ketamine and (S)-ketamine. Here, we examined the effects of two ketamine enantiomers on the dextran sulfate sodium (DSS)-induced colitis model of UC. Ingestion of 3% DSS in drinking water for 14 days increased the scores of Disease Activity Index (DAI) in mice. Repeated administration of (R)-ketamine (10 mg/kg/day, 14 days or last 7 days), but not (S)-ketamine (10 mg/kg/day, 14 days or last 7 days), significantly ameliorated the increased DAI score and increased blood levels of interleukin-6 (IL-6) in DSS-treated mice. In addition, (R)-ketamine, but not (S)-ketamine, attenuated the reduced colonic length in DSS-treated mice. Furthermore, DSS-induced increased DAI score and blood IL-6 levels were significantly ameliorated after subsequent repeated administration of (R)-ketamine (10 mg/kg/day for last 7 days), but not 5-aminosalicyclic acid (50 mg/kg/day for last 7 days). Moreover, the pretreatment with a tropomyosin-receptor-kinase B (TrkB) antagonist ANA-12 (0.5 mg/kg) significantly blocked the beneficial effects of (R)-ketamine in DSS-induced UC model. The study shows that (R)-ketamine can produce beneficial effects in DSS-induced colitis model through TrkB stimulation. Therefore, (R)-ketamine may be a novel therapeutic drug for inflammatory bowel diseases such as UC.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Dilodendron bipinnatum (Sapindaceae) stem bark decoction and macerate were used to treat uterine inflammation, pain in general, dermatitis and bone fractures. These homemade preparations also have diuretic, stimulant, expectorants and sedative effects and are effective in treating worm infections in the Brazilian Pantanal population. Our previous research confirmed the anti-inflammatory activity of the hydroethanolic extract of inner stem bark of D. bipinnatum (HEDb). AIM This work aimed to investigate the efficacy of HEDb in ameliorating experimental colitis in rats and to elucidate the possible mechanisms involved in the anti-ulcerative colitis properties of HEDb in rats and Caco-2 cell line. MATERIALS AND METHODS The effects on cell viability, IL-8 and TNF-α in human colon adenocarcinoma (Caco-2) were determined by flow cytometer and ELISA. Wistar rats (n = 6-7) were orally gavaged with, vehicle (0.9% saline), HEDb at doses of 20, 100 or 500 mg/kg, or mesalazine at a dose of 500 mg/kg, at 48, 24 and 1 h prior to the administration of trinitrobenzene sulfonic acid via rectal administration to induce colitis. The anti-inflammatory effects of HEDb were assessed macroscopically, by myeloperoxidase (MPO) activity and for glutathione (GSH) concentration in the colon. Additionally, colonic histopathological analyses of UC severity were conducted by different staining methods (H&E, PAS and toluidine blue). Pro-inflammatory cytokines TNF-α and IL-1β were quantified in colonic tissue by ELISA and colonic expressions of COX-2 and IL-17 were analyzed by western blotting. RESULTS HEDb was shown to be non-cytotoxic with mean viability of 80% in Caco-2 cells. HEDb pre-treatments of 1, 5 or 20 μg/mL significantly reduced TNF-α production in Caco-2 cells by 21.8% (p < 0.05), 60.5 and 82.1% (p < 0.001) respectively following LPS treatment compared to LPS alone. However, no change in IL-8 production was observed. HEDb pre-treatment of rats subjected to TNBS significantly (p < 0.001) reduced colonic lesion score. Higher doses (100 and 500 mg/kg) caused a sharp downregulation of haemorrhagic damage, leukocyte infiltration, edema and restoration of mucus production. Moreover, mast cell degranulation was inhibited. Colonic MPO activity was reduced following all doses of HEDb, reaching 51.1% ± 1.51 (p < 0.05) with the highest dose. GSH concentration was restored by 58% and 70% following 100 and 500 mg/kg of HEDb, respectively. The oral treatment of HEDb at doses 20, 100 and 500 mg/kg decreased the concentrations of TNF-α and IL-1β at all doses in comparison to vehicle treated control. In addition, HEDb inhibited the COX-2 and IL-17 expressions with maximal effect at 500 mg/kg (60.3% and 65% respectively; p < 0.001). In all trials, the effect of HEDb at all doses being 20, 100 and 500 mg/kg was statistically comparable to mesalazine (500 mg/kg). CONCLUSIONS HEDb reduces colonic damage in the TNBS colitis model and relieves oxidative and inflammatory events, at least in part, by increasing mucus production, reducing leukocyte migration and reducing TNF-α (in vivo and in vitro), IL-1β, IL-17 and COX-2 expression. Therefore, HEDb requires further investigation as a candidate for treating IBD.

Abstract
AIM Ulcerative colitis (UC) is a common intestinal problem characterized by the diffusion of colon inflammation and immunity dysregulation. Nifuroxazide, a potent STAT-3 inhibitor, exhibits diverse pharmacological properties. The present study aimed to elucidate a novel anti-colitis mechanism of nifuroxazide against the acetic acid-induced UC model. METHODS Rats were grouped into control (received vehicle), UC (2 ml of 5% acetic acid by intrarectal infusion), UC plus sulfasalazine (100 mg/kg/day, P.O.), UC plus nifuroxazide (25 mg/kg/day, P.O.), and UC plus nifuroxazide (50 mg/kg/day, P.O.) and lasted for 6 days. RESULTS The present study revealed that nifuroxazide significantly reduced UC measures, hematological changes, and histological alteration. In addition, treatment with nifuroxazide significantly down-regulated serum CRP as well as the colonic expressions of MPO, IL-6, TNF-α, TLR-4, NF-κB-p65, JAK1, STAT-3, DKK1 in a dose-dependent manner. Besides, our results showed that the colonic Wnt expression was up-regulated with nifuroxazide treatment. In a dose-dependent manner, nifuroxazide markedly alleviated acetic acid-induced cellular infiltration and improved ulcer healing by increasing intestinal epithelial cell regeneration. SIGNIFICANCE Our results collectively indicate that nifuroxazide is an effective anti-colitis agent through regulation of colon inflammation and proliferation via modulation IL-6/STAT-3/Wnt signaling pathway.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Lonicerae Japonicae Caulis, the dried stem and branch of Lonicera japonica Thunb., is a Chinese Materia Medica known as Ren Dong Teng in Chinese with long use history in the traditional Chinese medicine (TCM) prescriptions. Lonicerae Japonicae Caulis possesses heat-clearing and detoxifying functions according to the TCM theory. In recent years, a large amount of experimental and clinical studies proved good anti-inflammatory effects of some heat-clearing and detoxifying herbs. The present study aims to reveal the anti-inflammatory property and functional substances of Lonicerae Japonicae Caulis. MATERIALS AND METHODS For anti-inflammatory activity test, LPS-induced RAW 264.7 macrophages, DSS-induced SPF male C57BL/6J mice model, and LPS-induced SPF male ICR mice model were used in vitro and in vivo, respectively. The behavioral changes, organ damage, and the expression of inflammatory factors such as TNT-α and IL-6 mRNA expression were measured for activity evaluation. Lonicerae Japonicae Caulis samples were prepared by solvent extraction and subsequent column chromatography. The main components were identified and determined using UPLC-UV analysis as well as NMR interpretation after purification. To testify the contribution of main components for the anti-inflammatory activity, different samples were also prepared by compound-knockout strategy. RESULTS Ethanol extract of Lonicerae Japonicae Caulis could attenuate sickness symptoms in mice such as diarrhea, less activity, and depression. It could also alleviate multiple organ damage, and significantly inhibit the expression of pro-inflammatory factors such as TNF-α, IL-1β, IL-6 and IFN-γ in mice. Furthermore, the isochlorogenic acid-rich and biflavonoid-rich fractions and isochlorogenic acids A and C, and ochnaflavone could significantly down-regulate the mRNA expression of TNF-α and IL-6 in LPS-induced RAW 264.7 macrophages. CONCLUSIONS Lonicerae Japonicae Caulis possesses anti-inflammatory property. Its isochlorogenic acid-rich and biflavonoid-rich fractions do the major contribution. And their main components, isochlorogenic acids A and C, and ochnaflavone, take main responsibility for the anti-inflammatory property.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ulcerative colitis (UC) is a relapsing inflammatory disease that still demands for effective remedies due to various adverse effects of the current principal treatments. Centella asiatica is a traditional medical herb with long application history in anti-inflammation. AIM OF THE STUDY To explore the anti-inflammatory effect and possible mechanism of C. asiatica ethanol extract (CA) in a murine colitis model induced by dextran sulfate sodium (DSS). MATERIALS AND METHODS CA was analyzed by high performance liquid chromatograph (HPLC). The colitis model was induced by free access to 3% DSS in distilled water for 7 days. CA (100, 200, and 400 mg/kg) and 5-aminosalicylic acid (5-ASA, 400 mg/kg) were administrated by gavage during the 7-day DSS challenge. At the end of experiment, mice were sacrificed and the brain, colon and cecum contents were harvested for analysis. Colitis was evaluated by disease activity index (DAI), colon length and colon lesion macroscopic score with hematoxylin-eosin staining. Myeloperoxidase (MPO) activity in colon and 5-hydroxytryptamine (5-HT) in brain were determined by ELISA. Tight junction protein expressions (ZO-1, E-Cadherin, Claudin-1) and c-Kit in colon were assessed by western blot and immunohistochemistry, respectively. Microbiota of cecum content was analyzed by 16S rRNA sequencing. RESULTS Data showed that with recovery on the colon length and histological structure, CA prominently decreased DAI and macroscopic score for lesion in the suffering mice. CA relieved the colitis by suppressing inflammatory cell infiltration with decreased MPO activity in the colon, and up-regulated the expression of tight junction protein (ZO-1, E-cadherin) to enhance the permeability of intestinal mucosa. Moreover, CA restored intestinal motility by promoting c-Kit expression in the colon and 5-HT in the brain. Moreover, CA was able to reshape the gut microbiota in the suffering mice. It increased the α-diversity and shifted the community by depleting the colitis-associated genera, Helicobacter, Jeotgalicoccus and Staphylococcus, with impact on several metabolism signaling pathways, which possibly contributes to the renovation on the impaired intestinal mucosal barrier. CONCLUSIONS CA displayed the anti-inflammatory activity against the DSS-induced colitis, which would possibly rely on the restoration on mucosa barrier and gut microbiota homeostasis, highlights a promising application of C. asiatica in the clinical treatment of UC.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Xian-He-Cao-Chang-Yan formula (XHCF) is consisting of six crude drugs including Agrimoniae Herba, Coptidis Rhizoma, Aucklandiae Radix, Cicadae Periostracum, Acori Tatarinowii Rhizoma, and Platycodonis Radix at the ratio of 5:1.5:1.5:1.5:1.5:1. It has been used to improve syndromes of ulcerative colitis (UC) for many years. AIM OF THE STUDY This study was designed to study the bioactive ingredients and therapeutic mechanisms of XHCF. MATERIALS AND METHODS The chemical profile of XHCF was characterized by UHPLC-QTOF-MS/MS. The effects and mechanisms of XHCF on UC were investigated in colitis mice induced by dextran sulfate sodium (DSS) and LPS-stimulated RAW 264.7 cells. RESULTS A total of 103 compounds were characterized in XHCF. XHCF could effectively improve acute colitis induced by DSS. More importantly, XHCF significantly decreased M1 macrophage markers (CD11c, IL-6 and IL-1β) whereas increased M2 macrophage markers (CD206) in colitis mice, suggesting it could regulate macrophage polarization. Furthermore, the levels of HK2 and lactic acid in colon tissues were significantly reduced by XHCF, indicating that XHCF could inhibit glycolysis. It also down-regulated HK2 expression in macrophages challenged by LPS. In addition, XHCF enhanced the phosphorylation of AMPK both in vivo and in vitro, suggesting the involvement of AMPK in XHCF function. CONCLUSIONS XHCF ameliorated DSS-induced colitis in mice via inhibition of M1 macrophage polarization, probably by the modulation of macrophage metabolic reprogramming via AMPK, contributing to its anti-inflammatory activity. The synergistic actions of multiple ingredients might be responsible for the therapeutic benefits of XHCF on UC.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ethnobotanical studies show that the infusion of the leaves from Copaifera malmei Harms (Fabaceae) has been utilized in the Brazilian traditional medicine to treat provocative and gastrointestinal diseases, among others. Recently, our research team has shown that an infusion extract of the leaves of C. malmei has a strong antiulcer activity and its oral use gives no indications of toxicity. AIM OF THE STUDY The aim of the study is to evaluate the anti-inflammatory intestinal effect of an infusion extract from the leaves of Copaifera malmei (IECm) in an animal model of ulcerative colitis induced by 2,4,6-trinitrobenzenesulfonic acid (TNBS). MATERIALS AND METHODS Acute intestinal inflammation was induced in male Wistar rats by TNBS in 20% EtOH (0.25 mL). IECm was administered by oral gavage (for 72, 48, 24 and 2 h) preceding the induction of ulcerative colitis. The colon damage and degree of inflammation were evaluated by morphological observation scores and colon weight. The improved colonic mucosal injury, oxidative stress and inflammatory response were assessed by histopathological investigation and by estimating myeloperoxidase (MPO) activity, malondialdehyde (MDA) and glutathione (GSH) levels and tumor necrosis factor (TNF), interleukin 1β (IL1-β), IL-17 and IL-10 colon tissue concentrations. The histopathological changes were done on the colon tissues by hematoxylin and eosin and Periodic Acid-Schiff staining were utilized to measure the mucus. RESULTS Pre-treatment (25, 100 and 400 mg/kg) with IECm altogether diminished the intestinal inflammation prompted by TNBS in rats by diminishing colonic score by 69.12% (p < 0.01), 19.87% (p < 0.05) and 67.60% (p < 0.01), individually. Improvement of colonic mucosal injury by treatment with IECm was shown by a decline in MPO activity at dosages 25 and 400 mg/kg by 67.98% and 59.68% (p < 0.001), MDA levels 64.80% and 80.00% (p < 0.01) and an expansion in GSH content at all portions (62.53%, 53.38% and 81.20% p < 0.05) compared with vehicle control group. IECm additionally prevention of intestinal inflammation as confirm by decreased cytokine levels, for example, TNF (31.26%, p < 0.05, 50.68% and 45.95%, p < 0.01), IL1-β (56.41%, 58.83% and 56.65%, p < 0.001), IL-17 (51.66%, p < 0.001, 22.23%, p < 0.05 and 49.67%, p < 0.001) and increased the IL-10 levels at 25 and 400 mg/kg (57.13%, p < 0.01 and 35.83%, p < 0.05) respectively. Histopathological examination of the colon tissue displayed recovery of ulcerative colitis of IECm treated animals by reducing leukocyte infiltrate, epithelial, submucosal and muscular layer damages and maintaining mucus production. CONCLUSION These findings revealed that IECm was effective and possess anti-colitic activities in a rodent model of UC and can be useful in inflammatory bowel diseases (IBD). The pre-treatment with IECm decreased intestinal inflammation by reducing macroscopical and microscopical colon injury. In addition, the present study demonstrated that IECm ameliorates TNBS-colitis by promoting antioxidant effect, modulation of cytokines release and restauration of mucus production. The study reinforces the traditional use of the Copaifera malmei leaves infusion to inflammatory gastrointestinal disorders and makes IECm a potential herbal medicine for the treatment of IBD.

Abstract
With the epidemic of human obesity, dietary fats have increasingly become a focal point of biomedical research. Epidemiological studies indicate that high-fat diets (HFDs), especially those rich in long-chain saturated fatty acids (e.g., Western Diet, National Health Examination survey; NHANES 'What We Eat in America' report) have multi-organ pro-inflammatory effects. Experimental studies have confirmed some of these disease associations, and have begun to elaborate mechanisms of disease induction. However, many of the observed effects from epidemiological studies appear to be an over-simplification of the mechanistic complexity that depends on dynamic interactions between the host, the particular fatty acid, and the rather personalized genetics and variability of the gut microbiota. Of interest, experimental studies have shown that certain saturated fats (e.g., lauric and myristic fatty acid-rich coconut oil) could exert the opposite effect; that is, desirable anti-inflammatory and protective mechanisms promoting gut health by unanticipated pathways. Owing to the experimental advantages of laboratory animals for the study of mechanisms under well-controlled dietary settings, we focus this review on the current understanding of how dietary fatty acids impact intestinal biology. We center this discussion on studies from mice and rats, with validation in cell culture systems or human studies. We provide a scoping overview of the most studied diseases mechanisms associated with the induction or prevention of Inflammatory Bowel Disease in rodent models relevant to Crohn's Disease and Ulcerative Colitis after feeding either high-fat diet (HFD) or feed containing specific fatty acid or other target dietary molecule. Finally, we provide a general outlook on areas that have been largely or scarcely studied, and assess the effects of HFDs on acute and chronic forms of intestinal inflammation.

Abstract
Ulcerative colitis (UC) is chronic disease characterized by diffuse inflammation of the mucosa of the colon and rectum. Although the etiology is unknown, dysregulation of the intestinal mucosal immune system is closely related to UC. Cinnamaldehyde (CA) is a major active compound from cinnamon, is known as its anti-inflammatory and antibacterial. However, little research focused on its regulatory function on immune cells in UC. Therefore, we set out to explore the modulating effects of CA on immune cells in UC. We found that CA reduced the progression of colitis through controlling the production of proinflammatory cytokines and inhibiting the proportion of Th17 cells. Furthermore, the liquid chromatography-mass spectrometry (LC-MS) method was employed for analyzing and differentiating metabolites, data showed that sphingolipid pathway has a great influence on the effect of CA on UC. Meanwhile, sphingosine-1-phosphate receptor 2 (S1P2) and Rho-GTP protein levels were downregulated in colonic tissues after CA treatment. Moreover, in vitro assays showed that CA inhibited Th17 cell differentiation and downregulated of S1P2 and Rho-GTP signaling. Notably, we found that treatment with S1P2 antagonist (JTE-013) weakened the inhibitory effect of CA on Th17 cells. Furthermore, S1P2 deficiency (S1P2-/-) blocked the effect of CA on Th17 cell differentiation. In addition, CA can also improve inflammation via lncRNA H19 and MIAT. To sum up, this study provides clear evidence that CA can ameliorate ulcerative colitis through suppressing Th17 cells via S1P2 pathway and regulating lncRNA H19 and MIAT, which further supports S1P2 as a potential drug target for immunity-mediated UC.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In folk medicine Hyptis suaveolens (Lamiaceae) has been reported to relieve respiratory and gastrointestinal infections, indigestion, cold, pain, fever, cramps, skin diseases, gastric ulcer and inflammatory disorders. This study investigated the effects and the mechanisms of action of Hyptis suaveolens (L.) Poit (Lamiaceae) ethanol extract (Hs-EtOH) and hexane phase (Hs-HexF) against intestinal inflammation. MATERIAL AND METHODS Acute and relapse TNBS-induced ulcerative colitis protocols were used to evaluate intestinal anti-inflammatory activity. Damage evaluations, biochemical, histological and immunostaining parameters were determined. RESULTS Both extracts decreased macroscopic colonic inflammation and the area of lesion induced by TNBS. Nevertheless, only Hs-HexF was able to reduce colonic wall thickness, edema and diffuse inflammatory cell infiltration and to prevent GSH depletion in the acute model of ulcerative colitis. In the chronic phase with relapse of colonic ulceration, yet again only Hs-HexF significantly attenuated inflammatory parameters and presented a decrease in nitrite/nitrate, MDA, MPO, IL-1-β and TNF-α and increased levels of SOD, CAT, GSH and IL-10. Hs-HexF also significantly reduced positive cells immunostained for PCNA. CONCLUSION The data indicate intestinal anti-inflammatory activity for H. suaveolens, due to the participation of the antioxidant system, decreased neutrophil infiltration and cytokine modulation, as well as, owing to regulation of cell proliferation.

Abstract
Medical care for individuals with ulcerative colitis (UC) has become increasingly subspecialized, and this population presents unique challenges in the delivery of care. Most points of contact are with gastroenterology subspecialty clinics, and primary care providers have shown concern and unfamiliarity about managing these individuals. Gastroenterology subspecialists need to be comfortable discussing the unique preventive care needs of patients with UC, tailored to specific recommendations based on their demographics and current medication usage. This article reviews pertinent topics in preventive care for individuals with UC to provide a framework for gastroenterology subspecialists to be able to provide patient-centered care.

Abstract
Watermelon (Citrulus lantus) is an important horticultural crop which belongs to the Curcubitaceae family. The nutraceutical potential of watermelon has been illustrated by several researchers, which makes it a better choice of functional food. Watermelon has been used to treat various ailments, such as cardio-vascular diseases, aging related ailments, obesity, diabetes, ulcers, and various types of cancers. The medicinal properties of watermelon are attributed by the presence of important phytochemicals with pharmaceutical values such as lycopene, citrulline, and other polyphenolic compounds. Watermelon acts as vital source of l-citrulline, a neutral-alpha amino acid which is the precursor of l-arginine, an essential amino acid necessary for protein synthesis. Supplementation of l-citrulline and lycopene displayed numerous health benefits in in vitro and in vivo studies. Similarly, the dietary intake of watermelon has proven benefits as functional food in humans for weight management. Apart from the fruits, the extracts prepared from the seeds, sprouts, and leaves also evidenced medicinal properties. The present review provides a comprehensive overview of benefits of watermelon for the treatment of various ailments.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Fuzi and ganjiang are widely used as traditional Chinese medicines (TCM) in China, Korea, Japan, and many other southeast Asian countries for treating ulcerative colitis (UC), emesis and heart failure for more than 1800 years. However, the underlying mechanism of fuzi, ganjiang and fuzi-ganjiang herb pair is still unclear. In our study, we explored the therapeutic effects of fuzi, ganjiang and fuzi-ganjiang herb pair against dextran sulfate sodium (DSS)-induced UC in mice model, along with the relevant mechanism. MATERIALS AND METHODS The contents of each marker compound in fuzi decoction (FD), ganjiang decoction (GD) and fuzi-ganjiang decoction (FGD) were determined using LC-MS/MS. During the experiment, bodyweight changes in each group were monitored every 5 days. On the day of sacrifice, colonic length, disease activity index (DAI) and spleen weight were also evaluated and histopathological examination was performed through hematoxylin & eosin (H&E) staining. The levels of myeloperoxidase (MPO) and inflammatory cytokines in colon tissues were determined by enzyme-linked immunosorbent assay (ELISA), and then the relative mRNA productions of inflammatory mediators, such as MPO, inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX)-2 were measured by real-time polymerase chain reaction (PCR). Involvement of MAPK, STAT3 and NF-κB signaling pathways in the pathogenesis of UC was determined in each group using Western Blot (WB) analysis. RESULTS Compared with fuzi and ganjiang single decoction, the content of the alkaloids derived from fuzi (especially the diester alkaloid with strong toxicity, hypaconitine) in fuzi-ganjiang herb pair decoction was reduced. Additionally, the 6-gingerol, which was not found in ganjiang single decoction, was retained in fuzi-ganjiang herb pair decoction. FD, GD, and FGD significantly restored the bodyweight reduction, colon shortening, DAI elevation, splenomegaly and histological score in DSS-induced UC mice. Furthermore, except for the failure of low dosage of ganjiang decoction (GD-L) on IL-17A, all FD, GD and FGD significantly inhibited the production of MPO and inflammatory cytokines, such as IFN-γ, TNF-α, IL-1β, IL-6, IL-10 and IL-17A, and suppressed the relative expression of inflammatory mediators, such as MPO, iNOS and COX-2 mRNA in colon tissues of DSS-induced mice. According to WB analysis, fuzi, ganjiang and fuzi-ganjiang combination inhibited the activation of MAPK, NF-κB and STAT3 signaling pathways. CONCLUSIONS Our study demonstrated that fuzi, ganjiang and fuzi-ganjiang combination possess prominent anti-inflammatory activities against DSS-induced UC mice; the involved mechanism may be related to inhibition the activation of MAPK, NF-κB, and STAT3 signaling pathways.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Physalin B is one of the main active withanolide existed in Physalis alkekengi L. var. franchetii (Mast.) Makino, a famous traditional Chinese food and herbal medicine, which has been widely used as heat-clearing and toxin-resolving medicine for the treatment of various inflammatory disease, such as cough, excessive phlegm, pharyngitis, sore throat, pemphigus, eczema, and jaundice. AIM OF THE STUDY We aimed to confirm the therapeutic effects of Physalin B on ulcerative colitis (UC) and enrich the further application of its traditional anti-inflammatory effect. MATERIALS AND METHODS The anti-UC effects of Physalin B were evaluated in Balb/c mice with dextran sulfate sodium (DSS) induction. The body weight, colon length, disease activity index (DAI) and pathological changes of colon tissue were measured. Cytokine levels were detected by ELISA. NF-κB pathway and protein levels of related pathways, such as signal transducer and activator of transcription 3 (STAT3), β-arrestin1 and NOD-like receptor pyrin domain-containing protein 3 (NLRP3) inflammasome were detected by western blot. RESULTS The dose of Physalin B that is not cytotoxic could dramatically reduce the levels of TNF-α, IL-6 and IL-1β on LPS-stimulated RAW 264.7 cells. Meanwhile, Physalin B dramatically improved clinical signs and symptoms, alleviated body weight loss and colon length shortening in DSS-induced UC mice. Meanwhile, Physalin B also dramatically relieved the pathological damage, reduced in the activity of myeloperoxidase (MPO) and reestablished the balance of pro-inflammatory cytokines. Physalin B could suppress DSS-induced activation of NF-κB. Moreover, Physalin B also markedly suppressed the activation of STAT3, β-arrestin1 and NLRP3 inflammasome. CONCLUSION This study preliminary confirmed the therapeutic effect of Physalin B on experimental acute UC mice and provided robust evidence support for the anti-inflammatory effect of Physalin B, suggesting that Physalin B might be a potential agent for the therapeutic efficacy on UC.

Abstract
Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) with increasing incidence and prevalence in developed countries. The presence of inflammatory cytokines is considered the main detrimental factor in severe types of IBD. The Nrf2 transcription factor plays an important role in reducing the expression of inflammatory agents such as interleukin (IL)-1β and increasing reparative factors such as IL-11. Resveratrol, a plant-derived phenolic compound, reduces the damage in chronic experimentally induced colitis. Twenty patients with UC and also 20 healthy controls were recruited in this study. The proteins expression of Nrf2 and IL-1β was assessed in colonic biopsies by Western blotting. Caco-2 cells were challenged with TNF-α (in vitro simulation of UC), in the presence or not of 190 nM (24 h) and 75 nM (48 h) Resveratrol. Then, Nrf2 and IL-1β in gene and protein expression were measured by real time-PCR and Western blotting in different treatments. Finally, IL-11 proteins expression was measured in culture supernatant by ELISA. A significant increase of IL-1β protein was detected in inflamed colonic tissues from UC patients compared with the control individuals. In Caco-2 cells challenged with TNF-α, protein expression of IL-1β and p-Nrf2 showed an increase, while gene expression of Nrf2 did not show a significant difference. After treatment with Resveratrol, both IL-1β mRNA and protein levels were reduced, while IL-11 protein levels showed any increase. The p-Nrf2 is a dominant form which is prevalent in inflamed tissues from UC patients. Resveratrol can reverse the inflammatory effects of TNF-α by reducing IL-1β and increasing IL-11 production.

Abstract
BACKGROUND Oral 5-aminosalicylic acid (5-ASA; also known as mesalazine or mesalamine) preparations were intended to avoid the adverse effects of sulfasalazine (SASP) while maintaining its therapeutic benefits. In an earlier version of this review, we found that 5-ASA drugs were more effective than placebo for maintenance of remission of ulcerative colitis (UC), but had a significant therapeutic inferiority relative to SASP. In this version, we have rerun the search to bring the review up to date. OBJECTIVES To assess the efficacy, dose-responsiveness, and safety of oral 5-ASA compared to placebo, SASP, or 5-ASA comparators for maintenance of remission in quiescent UC and to compare the efficacy and safety of once-daily dosing of oral 5-ASA with conventional (two or three times daily) dosing regimens. SEARCH METHODS We performed a literature search for studies on 11 June 2019 using MEDLINE, Embase, and the Cochrane Library. In addition, we searched review articles and conference proceedings. SELECTION CRITERIA We included randomized controlled trials with a minimum treatment duration of six months. We considered studies of oral 5-ASA therapy for treatment of participants with quiescent UC compared with placebo, SASP, or other 5-ASA formulations. We also included studies that compared once-daily 5-ASA treatment with conventional dosing of 5-ASA and 5-ASA dose-ranging studies. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. The primary outcome was the failure to maintain clinical or endoscopic remission. Secondary outcomes were adherence, adverse events (AE), serious adverse events (SAE), withdrawals due to AEs, and withdrawals or exclusions after entry. Trials were separated into five comparison groups: 5-ASA versus placebo, 5-ASA versus SASP, once-daily dosing versus conventional dosing, 5-ASA (balsalazide, Pentasa, and olsalazine) versus comparator 5-ASA formulation (Asacol and Salofalk), and 5-ASA dose-ranging. We calculated the risk ratio (RR) and 95% confidence interval (CI) for each outcome. We analyzed data on an intention-to-treat basis, and used GRADE to assess the overall certainty of the evidence. MAIN RESULTS The search identified 44 studies (9967 participants). Most studies were at low risk of bias. Ten studies were at high risk of bias. Seven of these studies were single-blind and three were open-label. 5-ASA is more effective than placebo for maintenance of clinical or endoscopic remission. About 37% (335/907) of 5-ASA participants relapsed at six to 12 months compared to 55% (355/648) of placebo participants (RR 0.68, 95% CI 0.61 to 0.76; 8 studies, 1555 participants; high-certainty evidence). Adherence to study medication was not reported for this comparison. SAEs were reported in 1% (6/550) of participants in the 5-ASA group compared to 2% (5/276) of participants in the placebo group at six to 12 months (RR 0.60, 95% CI 0.19 to 1.84; 3 studies, 826 participants; low-certainty evidence). There is probably little or no difference in AEs at six to 12 months' follow-up (RR 0.93, 95% CI 0.73 to 1.18; 5 studies, 1132 participants; moderate-certainty evidence). SASP is more effective than 5-ASA for maintenance of remission. About 48% (416/871) of 5-ASA participants relapsed at six to 18 months compared to 43% (336/784) of SASP participants (RR 1.14, 95% CI 1.03 to 1.27; 12 studies, 1655 participants; high-certainty evidence). Adherence to study medication and SAEs were not reported for this comparison. There is probably little or no difference in AEs at six to 12 months' follow-up (RR 1.07, 95% CI 0.82 to 1.40; 7 studies, 1138 participants; moderate-certainty evidence). There is little or no difference in clinical or endoscopic remission rates between once-daily and conventionally dosed 5-ASA. About 37% (717/1939) of once-daily participants relapsed over 12 months compared to 39% (770/1971) of conventional-dosing participants (RR 0.94, 95% CI 0.88 to 1.01; 10 studies, 3910 participants; high-certainty evidence). There is probably little or no difference in medication adherence rates. About 10% (106/1152) of participants in the once-daily group failed to adhere to their medication regimen compared to 8% (84/1154) of participants in the conventional-dosing group (RR 1.18, 95% CI 0.72 to 1.93; 9 studies, 2306 participants; moderate-certainty evidence). About 3% (41/1587) of participants in the once-daily group experienced a SAE compared to 2% (35/1609) of participants in the conventional-dose group at six to 12 months (RR 1.20, 95% CI 0.77 to 1.87; moderate-certainty evidence). There is little or no difference in the incidence of AEs at six to 13 months' follow-up (RR 0.98, 95% CI 0.92 to 1.04; 8 studies, 3497 participants; high-certainty evidence). There may be little or no difference in the efficacy of different 5-ASA formulations. About 44% (158/358) of participants in the 5-ASA group relapsed at six to 18 months compared to 41% (142/349) of participants in the 5-ASA comparator group (RR 1.08, 95% CI 0.91 to 1.28; 6 studies, 707 participants; low-certainty evidence). AUTHORS' CONCLUSIONS There is high-certainty evidence that 5-ASA is superior to placebo for maintenance therapy in UC. There is high-certainty evidence that 5-ASA is inferior compared to SASP. There is probably little or no difference between 5-ASA and placebo, and 5-ASA and SASP in commonly reported AEs such as flatulence, abdominal pain, nausea, diarrhea, headache, and dyspepsia. Oral 5-ASA administered once daily has a similar benefit and harm profile as conventional dosing for maintenance of remission in quiescent UC.

Abstract
Ulcerative colitis (UC) is a chronic and relapsing inflammatory disorder of the gastrointestinal tract, characterized by diarrhea, hematochezia, abdominal distension, and abdominal pain. The perpetuation of inflammation and the impairment of the intestinal barrier are part of the main courses of UC, responsible for the deteriorating inflammatory condition. Patchouli alcohol (PA), extracted from Pogostemon cablin Benth., is employed to treat both inflammation and intestinal barrier damage. Its curative effect on UC was testified firstly by TNBS-induced UC, a chemically induced colitis, and further tested by DSS-induced UC, an acute attack stage of UC in which the clinical course of human UC occurs frequently. PA reduced the levels of TNF-α, IFN-γ, IL-1β, IL-6, and IL-17 in serum and decreased the mRNA expression of pro-inflammatory cytokines (e.g., iNOS, COX-2, TNF-α, IL-1β, and IL-6). Concurrently, PA upregulated the expression of tight junction protein (e.g., ZO-1, ZO-2, claudin-1, and occludin) and the mRNA of mucin-1 and mucin-2 in both animal models. Further, PA ameliorated both histological damage and clinical parameters. Thus, PA could credibly reduce the expression of pro-inflammatory cytokines, protect the integrity of intestinal epithelial barrier, and repair the macroscopic colon lesions in both colitis models.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Sophora alopecuroides L. is one of the most commonly used plants in traditional medicine for the management conditions including inflammatory and gastrointestinal disease. However, the therapeutic mechanism of Sophora alopecuroides L.particularly in inflammatory bowel disease (IBD) remains unclear. AIM OF THE STUDY To evaluate the treatment effects of total alkaloids of Sophora alopecuroides L. in ulcerative colitis (UC) mice model and explore the therapeutic mechanism of KDZ on UC based on bile acid metabolism and gut microbiota. MATERIALS AND METHODS Colitis were induced in BALB/c mice by administering 3.5% dextran sulfate sodium (DSS) in drinking water for 7 days. The mice were then given KDZ (300, 150 and 75 mg/kg) and the positive drug sulfasalazine (SASP, 450 mg/kg) via oral administration for 7 days. The levels of 23 bile acids in the liver, bile, serum, cecum content and colon were determined through ultra-performance liquid chromatography/tandem mass spectrometry (UPLC-MS/MS). The cecum microbiota was characterized through high-throughput Illumina MiSeq sequencing. RESULTS KDZ treatment significantly decreased the disease activity index (DAI) scores and ameliorated colonic injury in DSS-treated mice. The expression of IL-1β and TGF-β1 were suppressed, yet, IL-10 was up-regulated by KDZ and SASP treatment compared with those in the model group. Meanwhile, the serum contents of total bile acid and total cholesterol in the DSS group increased significantly compared with those in the control group, but reversed by SASP and KDZ. The relative abundance of Firmicutes increased after KDZ was administration, whereas the abundance of Bacteroidetes decreased. αMCA, βMCA, ωMCA and CA in the SASP and KDZ groups did not differ from those in the control group, whereas these parameters significantly increased in the DSS group. CONCLUSIONS KDZ had a protective effect on DSS-induced colitis by mitigating colonic injury, preventing gut microbiota dysbiosis and regulating bile acid metabolism.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Polyphenolics (flavonoid and phenolic) rich plants are the effective source for the treatment of acute and chronic degenerative diseases including inflammatory bowel disease. OBJECTIVE This study was aimed to examine the effects of polyphenolics rich leaf acetone extract of P. subpeltata against the indomethacin induced ulcerative colitis in rats. MATERIALS AND METHODS Two consecutive days administration of indomethacin produced chronic inflammation in GIT tissues of rats. Further, the plant extract 200 and 400 mg/kg treatment were continued until 11th day. Then hematological, enzymatic antioxidants, MPO and histological evaluations were analyzed. Moreover, the extracts were treated with RAW267.4 cells for the cytotoxicity, NO and TNF-α analysis. RESULTS The obtained results revealed, that higher dose of the plant extract dropped neutrophil infiltration followed by inhibiting the MPO enzyme levels and controls the enzymatic antioxidants such as SOD, CAT, GSH and LPO. RAW cells study also proved that the plant extract effectively inhibits NO and TNF-α production. CONCLUSIONS Thus, these results suggest that P. subpeltata extract may have therapeutic potential for the treatment of IBD although further clinical research is still warranted.

Abstract
OBJECTIVES The aim of this study was to evaluate the preventive effects of extra virgin olive oil (EVOO) or flaxseed oil (FO) on dextran sodium sulfate (DSS)-induced acute ulcerative colitis in female mice. METHODS Eighty C57BL/6J mice of 8-weeks-old were divided in four groups: Control (SO), 10%EVOO, 10%FO and 5%EVOO+5%FO. The oils were given through the AIN-93M diet. After 30 days, animals were divided in four more groups, in which half received 3%DSS in water for 5 days. Body weight loss, bleeding and stool consistency were verified for the Disease Activity Index (DAI). Animals were euthanized and their colon and spleen weighted and measured. Histopathological analysis, the concentrations of TNF-α, IL-1β, and IL-10 and the iNOS expression were evaluated in the colon samples. RESULTS Animals that received DSS presented with elevated disease activity index values; increased colon weight-to-length ratio; augmented leukocyte infiltration into the lamina propria and submucosa; and increased production of tumor necrosis factor (TNF)-α, interleukin (IL)-1β and IL-6, and greater inducible nitric oxide synthase expression in the distal colon. Individually or in combination, the oils were not able to reverse or mitigate any of the DSS-induced symptoms or damage. Additionally, the group of animals treated with DSS and supplemented with FO displayed increased spleen weight-to-body weight ratio, and the group that received a combination of EVOO and FO presented increased TNF-α levels compared with the respective control group. CONCLUSION Consumption of large amounts of EVOO and FO as a treatment for or prevention against ulcerative colitis could potentially elicit unwanted adverse effects.

Abstract
The pyruvate kinase M2 (PKM2)-mediated aerobic glycolysis has been shown to play a critical role in promoting cell survival and proliferation. However, little is known about the function of intestinal epithelial PKM2 in intestine homeostasis. Here we investigate whether and how intestinal epithelial PKM2 modulates the morphology and function of the adult intestine in experimental colitis. Analyzing colonoscopic biopsies from Crohn's disease and ulcerative colitis patients, we found significantly decreased level of intestinal epithelial PKM2 in patients compared to that in non-inflamed tissues. Similar reduction of intestinal epithelial PKM2 was observed in mice with dextran sulfate sodium-induced colitis. Moreover, intestinal epithelial-specific PKM2-knockout (Pkm2-/-) mice displayed more severe intestinal inflammation, as evidenced by a shortened colon, disruption of epithelial tight junctions, an increase in inflammatory cytokine levels, and immune cell infiltration, when compared to wild-type mice. Gene profiling, western blot, and function analyses indicated that cell survival signals, particularly the Wnt/β-catenin pathways, were associated with PKM2 activity. Increasing mouse intestinal epithelial PKM2 expression via delivery of a PKM2-expressing plasmid attenuated experimental colitis. In conclusion, our studies demonstrate that intestinal epithelial PKM2 increases cell survival and wound healing under the colitic condition via activating the Wnt/β-catenin signaling.

Abstract
BACKGROUND Psychiatric comorbidity might modify the disease course adversely in patients with inflammatory bowel disease (IBD). Treatment options include antidepressants, which, apart from improving mood, have anti-inflammatory properties that might modify the disease course. This nationwide study aimed to examine the influence of antidepressants on the disease course among patients with ulcerative colitis (UC) and Crohn's disease (CD). METHODS Patients registered with an incident diagnosis of CD or UC in the Danish National Patient Register (2000-2017) were included. Information on antidepressant use and proxy measures of disease activity (health care and drug utilization) was extracted from national population registers. Poisson regression was performed to estimate disease activity rates by antidepressant use adjusted for confounders. Furthermore, the analyses were performed stratified by IBD subtype and type of antidepressants. RESULTS A total of 42,890 patients were included (UC: 69.5%; CD: 30.5%). When adjusted for confounders, a lower incidence rate of disease activity was found among antidepressant users compared with nonusers in both CD (incidence rate ratio [IRR], 0.75; 95% confidence interval [CI], 0.68-0.82) and UC (IRR, 0.90; 95% CI, 0.84-0.95) patients. Further, markedly lower rates of disease activity were found among CD (IRR, 0.51; 95% CI, 0.43-0.62) and UC (IRR, 0.67; 95% CI, 0.59-0.75) patients with no use of antidepressants before IBD onset. CONCLUSIONS In this nationwide study, antidepressant use was found to be beneficial on the disease course among patients with UC and CD, particularly in patients with no use of antidepressants before IBD onset. Randomized controlled trials are warranted to investigate the potential of antidepressants being an adjunct treatment to conventional IBD therapy.

Abstract
Ulcerative colitis (UC) and Crohn's disease (CD) are classified as chronic inflammatory bowel diseases (IBD) which have similar symptoms and lead to digestive disorders and inflammation in the digestive system. The reason why they occur is still a mystery. A number of factors can be attributed to the prevalence of CD and UC, some of which include geographical location, inappropriate diet, genetics, and inappropriate immune response. Both diseases are more often diagnosed in urban areas compared to rural areas and both have their own challenges and side effects, but the patients can still have a good quality of life. Given the fact that the prevalence of this disease is higher at younger ages and that it disrupts half the life of the patient, it will, most likely, become a major health problem in the near future, even in developing countries. By reviewing valid scientific resources and evaluating new methods of addressing this disease, the present study aims to provide researchers and patients with new insights into this field and facilitate access to new treatments.

Abstract
Although traditionally used to improve indigestion, diarrhea, dysentery, and constipation, the therapeutic effects of Citrus aurantium on intestinal inflammation remain unclear. The aim of this study was to evaluate the beneficial effects and to identify the active components of a hydroalcoholic extract of C. aurantium (HECA) on ulcerative colitis. HECA was prepared with 70% ethanol solution in water and extracted at 37 °C for 12 h in triplicate, filtered through a sieve, and lyophilized. Phytochemical identification of HECA was performed by ultra-performance liquid chromatography-diode array detector-tandem mass spectrometry (UPLC-DAD-MS/MS). Animals were randomly assigned to one of four groups based on the treatment conditions. Ulcerative colitis was induced by administration of 2.5% dextran sodium sulfate (DSS) in drinking water for 5 d. Body weight, clinical signs, colon length, pro-inflammatory cytokine expression levels, and histopathological findings were evaluated. In UPLC-DAD-MS/MS analysis, the identified phytochemical components of HECA included four alkaloids, seven coumarins, 18 flavonoids, two lignans, two phenolics, and 10 terpenoids. HECA markedly protected against body weight loss and colon shortening. In pathological examination, HECA alleviated DSS-related mucosal inflammatory lesions in the colon. Moreover, HECA markedly reduced the expression levels of interleukin-6, interferon-γ, tumor necrosis factor-α, and monocyte chemotactic protein-1 in colonic inflammation. Taken together, HECA has potential to relieve mucosal inflammation in the colon, suggesting that the putative active ingredients are responsible for the anti-ulcerative effects.
