Abstract
Ulcerative colitis (UC), often known as UC, is an inflammatory disease of the intestines that has frequent and long-lasting flare-ups. It is unknown precisely how the traditional Chinese drug Indigo Naturalis (IN) heals inflammatory bowel disease, despite its long-standing use in China and Japan. Finding new metabolite biomarkers linked to UC could improve our understanding of the disease, speed up the diagnostic process, and provide insight into how certain drugs work to treat the condition. Our work is designed to use a metabolomic method to analyze potential alterations in endogenous substances and their impact on metabolic pathways in a mouse model of UC. To determine which biomarkers and metabolisms are more frequently connected with IN's effects on UC, liquid chromatography-tandem mass spectrometry analysis of the serum metabolomics of UC mice and normal mice was performed. The outcomes demonstrated that IN boosted the health of UC mice and reduced the severity of their metabolic dysfunction. In the UC model, it was also found that IN changed the way 17 biomarkers and 3 metabolisms functioned.

Abstract
Autoinflammatory disorders and autoimmune diseases result from abnormal deviations of innate and adaptive immunity that heterogeneously affect organs and clinical phenotypes. Despite having etiologic and phenotypic differences, these two conditions share the onset of an aberrant inflammatory process. Targeting the main drivers controlling inflammation is useful to treat both autoimmune and autoinflammatory syndromes. TNF-α is a major player in the inflammatory immune response, and anti-TNF-α antibodies have been a revolutionary treatment in many autoimmune disorders. However, production difficulties and high development costs hinder their implementation, and accessibility to their use is still limited. Innovative strategies aimed at overcoming the limitations associated with anti-TNF-α antibodies are being explored, including RNA-based therapies. Here we summarize the central role of TNF-α in immune disorders and how anti-TNF-based immunotherapies changed the therapeutic landscape, albeit with important limitations related to side effects, tolerance, and resistance to therapies. We then outline how nanotechnology has provided the final momentum for the use of nucleic acids in the treatment of autoimmune and autoinflammatory diseases, with a focus on inflammatory bowel diseases (IBDs). The example of IBDs allows the evaluation and discussion of the nucleic acids-based treatments that have been developed, to identify the role that innovative approaches possess in view of the treatment of autoinflammatory disorders and autoimmune diseases.

Abstract
Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) which is related to an immunological imbalance of the intestinal mucosa. Many clinical evidences indicate probiotics supplementation appears to be effective and safe in patients with UC. Vasoactive intestinal peptide (VIP) is an endogenous neuropeptide with multiple physiological and pathological effects. In this study, we investigated the protective effect of the combination of Lactobacillus casei ATCC 393 (L. casei ATCC 393) with VIP on dextran sodium sulfate (DSS)-induced UC in mice and the potential mechanism. The results showed that, compared with the control group, DSS treatment significantly shortened the colon length, caused inflammation and oxidative stress, and further resulted in the intestinal barrier dysfunction and gut microbiota dysbiosis. In addition, intervention with L. casei ATCC 393, VIP or L. casei ATCC 393 combined with VIP significantly reduced UC disease activity index. However, compared with L. casei ATCC 393 or VIP, L. casei ATCC 393 combined with VIP effectively relieved symptoms of UC by regulating immune response, enhancing antioxidant capacity, and regulating nuclear factor kappa-B (NF-κB) and nuclear factor erythroid-derived-2-like 2 (Nrf2) signaling pathways. In conclusion, this study suggests that L. casei ATCC 393 combined with VIP can effectively relieve DSS-induced UC, which is a promising treatment strategy for UC.

Abstract
Introduction: Polysaccharides from Grifola frondosa (Dicks.) Gray (HSH) and Inonotus obliquus (Fr.) Pilat (BHR) showed noticeable effects on dextran sulfate sodium (DSS)-induced colitis, but their systemic modulation effects have not been fully revealed. This study aimed to investigate the regulation of the gut microbiota and systemic metabolism by HSH and BHR in DSS-induced colitis. Methods: C57BL/6J mice were given DSS (2.5%) in water and were treated with HSH and BHR (200 mg/kg/day) by gavage. Body weight and colon length were recorded, and H&E and AB-PAS staining of the colon were conducted to evaluate the model and the protective effect of the polysaccharides. Additionally, an LC-QTOF/MS-based untargeted metabolomic platform was used to identify the metabolites in the serum, colon tissue, gut contents, and faeces and investigate differential metabolites and metabolic pathways. 16S rDNA gene sequencing was used to measure the composition of bacterial communities. Results: The results showed that the mouse colitis model was established successfully, as evidenced by an increased disease activity index score [2.83 ± 0.62 vs. 0.06 ± 0.14 (p < 0.001)] and shortened colon length [5.43 ± 0.64 cm vs. 7.04 ± 0.29 cm (p < 0.001)], and HSH and BHR ameliorated DSS-induced colitis by improving the disease activity index (2.17 ± 0.28 and 1.83 ± 0.29, respectively) and restoring the colon length (6.12 ± 0.30 cm and 6.62 ± 0.35 cm, respectively). HSH and BHR significantly modulated metabolites involved in aromatic amino acid metabolism, the citrate cycle, purine metabolism, pyrimidine metabolism, etc. HSH and BHR increased the Chao1 index by 64.25% and 60.25%, respectively, and they increased the Shannon index by 13.02% and 10.23%, respectively. They both reversed the increase in the abundances of g_Odoribacter, g_Clostridium, g_AF12, g_Parabacteroides and g_Turicibacter and reversed the decrease in the abundance of g_unclassified_Bacteria induced by DSS. Specifically, HSH reversed the reductions in g_unclassified_Lactobacillales and g_Ruminococcus, and BHR reversed the decreases in g_unidentified_Coriobacteriaceae and g_unclassified_Firmicutes. Discussion: These results suggested that HSH and BHR may ameliorate DSS-induced colitis by global modulation of systemic metabolism and the gut microbiota. Targeting the gut microbiota may be a potentially effective strategy to modulate systemic metabolism and treat colitis.

Abstract
BACKGROUND In Korea, infliximab was approved for use in children with ulcerative colitis (UC) in October 2012.
AIM To compare the clinical course of UC before and after the introduction of biological agents, and to compare with the IBSEN study.
METHODS Patients under 18 years of age, who were diagnosed with UC and followed from January 2003 to October 2020, were included in the study. Group A (n = 48) was followed for at least 2 years between January 2003 and October 2012, and Group B (n = 62) was followed for at least 2 years between November 2012 and October 2020. We compared endoscopic remission, drug composition, relapse rate, steroid-free period, and the quality of life of each group. We plotted the clinical course of the included patients using the pediatric UC activity index score, and compared our patients with those in the IBSEN study.
RESULTS After 2 years of treatment, colonoscopy evaluation revealed different outcomes in the two treatment groups. Remission was confirmed in 14 patients (29.2%) of Group A, and in 31 patients (50.0%) of Group B (P < 0.012). The median cumulative corticosteroid-free period was 3.0 years in Group A and 4.4 years in Group B. Steroid-free period of Group B was significantly longer than that of Group A (P < 0.001). There was a statistically significant difference between the two groups in evaluation of the relapse rate during the observation period (P < 0.001). The plotted clinical course graphs of Group A showed similar proportions to the graphs in the IBSEN study. However, in Group B, the proportion of patients corresponding to curve 1 (remission or mild severity after initial high activity) was high at 76% (47/62).
CONCLUSION The incidence of relapse has decreased and the steroid-free period has increased after the introduction of the biological agent. The clinical course also showed a different pattern from that of IBSEN study. The active use of biological agents may change the long-term disease course in moderate to severe pediatric UC.

Abstract
BACKGROUND Ulcerative colitis (UC) is one of the chronic diseases which is increasing in prevalence and patients suffer from illness flare-ups. UC standard regimen treatment has various side effects besides the efficacy, so there is an interest in administering complementary medicine to reduce adverse effects and increase the efficacy, as well. The aim of this study was to evaluate the efficacy and anti-inflammatory effect of Thymus kotschyanus as an additive treatment in a randomized double-blind placebo-controlled trial of UC patients. METHODS Thirty UC out-patients with mesalazine regimen treatment that fulfilled the inclusion criteria were participated in a 12 week trial and were randomly chosen for the treatment and control group. Fifteen patients were administered a placebo as a control and 15 patients were received Thymus kotschyanus extract by a dose of 0.5 g in a day in the treatment group. Laboratory tests were performed at baseline and week 12. The primary outcome was a reduction in fecal calprotectin as the main intestine inflammatory marker. Likewise, reduction in SCCAI, SIDBQ, and SEO indices were considered as secondary aims. RESULTS Fecal calprotectin was decreased by 54.74% in the treatment group, as compared with the placebo group at week 12 (p = 0.02). A significant reduction in SCCAI was also shown between the two study groups (p = 0.01). Thymus kotschyanus extract was safe and no severe side effects were reported. CONCLUSION Administration of Thymus kotschyanus revealed improvement in UC symptoms by the intestinal anti-inflammation effect of the plant and could be suggested as a potential additive treatment in UC patients. The study protocol has been registered under the identification code: IRCT20200406046965N2.

Abstract
OBJECTIVES To investigate the potential association between uveitis and an increased risk of developing inflammatory bowel disease (IBD). METHODS We conducted a retrospective cohort study by interrogating data from the Taiwan National Health Insurance Research Database entered between January 1, 2001 and December 31, 2013 to identify uveitis patients and age- and gender-matched controls. The cumulative incidence rates of subsequent IBD in the two groups were compared. The adjusted hazard ratio (HR) of IBD related to uveitis was generated by a multivariate cox regression model after adjustment for hypertension, diabetes, hyperlipidaemia, obesity and smoking. Furthermore, the HRs of the Crohn's disease (CD) and ulcerative colitis (UC) IBD subtypes were calculated separately. RESULTS A total of 198,923 subjects with uveitis and 397,846 controls were enroled. The mean age of the cohort was 47.7 ± 18.9 years. A significantly higher cumulative incidence of IBD was found in the uveitis group than in controls (4.13% vs. 1.48%, p < 0.0001). Under univariate cox regression analysis, uveitis patients had a significantly higher risk of IBD (HR = 1.47; 95% confidence interval (CI): 1.43-1.52, p < 0.0001). The association remained significant in the multivariate regression model, with an adjusted HR of 1.44 (95% CI: 1.39-1.49, p < 0.0001). Moreover, in subgroup analysis, uveitis was significantly associated with an increased risk of Crohn's disease (adjusted HR = 1.49; 95% CI: 1.44-1.54), but not with ulcerative colitis (adjusted HR = 1.03; 95% CI: 0.92-1.15). CONCLUSIONS Patients with uveitis are at significantly greater risk of developing IBD than individuals without uveitis.

Abstract
The novel coronavirus pandemic has emerged as one of the significant medical-health challenges of the current century. The World Health Organization has named this new virus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Since the first detection of SARS-CoV-2 in November 2019 in Wuhan, China, physicians, researchers, and others have made it their top priority to find drugs and cures that can effectively treat patients and reduce mortality rates. The symptoms of Coronavirus Disease 2019 (COVID-19) include fever, dry cough, body aches, and anosmia. Various therapeutic compounds have been investigated and applied to mitigate the symptoms in COVID-19 patients and cure the disease. Degenerative virus analyses of the infection incidence and COVID-19 have demonstrated that SARS-CoV-2 penetrates the pulmonary alveoli's endothelial cells through Angiotensin-Converting Enzyme 2 (ACE2) receptors on the membrane, stimulates various signaling pathways and causes excessive secretion of cytokines. The continuous triggering of the innate and acquired immune system, as well as the overproduction of pro-inflammatory factors, cause a severe condition in the COVID-19 patients, which is called "cytokine storm". It can lead to acute respiratory distress syndrome (ARDS) in critical patients. Severe and critical COVID-19 cases demand oxygen therapy and mechanical ventilator support. Various drugs, including immunomodulatory and immunosuppressive agents (e.g., monoclonal antibodies (mAbs) and interleukin antagonists) have been utilized in clinical trials. However, the studies and clinical trials have documented diverging findings, which seem to be due to the differences in these drugs' possible mechanisms of action. These drugs' mechanism of action generally includes suppressing or modulating the immune system, preventing the development of cytokine storm via various signaling pathways, and enhancing the blood vessels' diameter in the lungs. In this review article, multiple medications from different drug families are discussed, and their possible mechanisms of action are also described.

Abstract
Aiming at assessing the therapeutic effect of ethyl rosmarinate (ER) on ulcerative colitis (UC), the following activities were performed in vitro and in vivo in the present study. Firstly, a lipopolysaccharide (LPS)-induced RAW264.7 cell inflammation model was established to determine the level of inflammatory factors. Then, a UC mice model induced by dextran sodium sulfate (DSS) was established to further investigate the effects of ER on symptoms, inflammatory factors and colon histopathology. Finally, serum and colon metabolomics studies were performed to identify the biomarkers and metabolisms closely related to the protective effect of ER on UC. The results showed that after ER intervention, the levels of inflammatory factors (NO, TNF-α, IL-1β and IL-6) and key enzyme (MPO) in cell supernatant, serum or colon were significantly decreased, and the disease activity index and colon tissue damage in mice were also effectively improved or restored. In addition, 28 biomarkers and 6 metabolisms were found to be re-regulated by ER in the UC model mice. Therefore, it could be concluded that ER could effectively ameliorate the progression of UC and could be used as a new natural agent for the treatment of UC.

Abstract
Purpose: Mesenchymal stem cells (MSCs) have immunomodulatory traits making them a promising choice in the treatment of inflammatory diseases such as graft-versus-host disease (GVHD). Tumor necrosis factor-alpha (TNFα) is a major player of inflammatory disease which is blocked by infliximab to reduce the inflammation. The present study aims to assess the infliximab effects on the anti-inflammatory properties of MSCs. Methods: In this study, bone marrow mesenchymal stem cells (BMMSCs) were co-cultured with peripheral blood mononuclear cells (PBMCs) of GVHD patients in the presence of 10, 20 and 30 µg/mL of infliximab for 48 and 72 hours. The mRNA expression of indoleamine-2,3- dioxygenase (IDO) and inducible nitric oxide synthase (iNOS), as well as the secreted amount of prostaglandin E2 (PGE2) in the culture supernatant, were examined. Results: The results of this study show that the expression of IDO and iNOS genes, as well as the secretion amount of PGE2 in co-cultured groups raised dramatically, compared to the culture of BMMSCs or PBMCs alone. In co-culture groups containing infliximab, the expression of IDO and iNOS and also the amount of released PGE2 was significantly decreased compared to the control group without infliximab. However, no difference was found in the expression of assayed factors between 48 and 72 hours of treatments. Conclusion: As an anti-TNFα agent, infliximab can decrease the inflammation in the microenvironment of MSCs, which might mitigate the immunomodulatory effects of MSCs. These effects of anti-inflammatory agents on the immunomodulatory capacity of MSCs should be considered in MSC therapy.

Abstract
The human digestive tract is the cottage to trillions of live microorganisms, which regulate health and illness. A healthy Gut Microbiota (GM) is necessary for preventing microbial growth, body growth, obesity, cancer, diabetes, and enhancing immunity. The equilibrium in GM's composition and the presence/absence of critical species enable specific responses to be essential for the host's better health condition. Research evidences revealed that the dietary plants and their bioactive phytochemicals (BPs) play an extensive and critical role in shaping the GM to get beneficial health effects. BPs are also known to improve gastrointestinal health and reduce the risk of several diseases by modulating GM-mediated cellular and molecular processes. Regular intake of BPs-rich vegetables, fruits, and herbal preparations promotes probiotic bacteria, including Bifidobacteria and Lactobacillus species, while inhibiting unwanted gut residents' development Escherichia coli, and Salmonella typhimurium etc. Upon consumption, BPs contact the GM that gets transformed before being absorbed from the gastrointestinal tract. Biotransformation of BPs by GM is linked with the enhancement of bioactivity/toxicity diminishment of the BPs compared to parental phytochemicals. Therefore, the current review focuses on the role of BPs in shaping GM for the prevention and treatment of human diseases.

Abstract
A 25-year-old man was admitted to our institution for remission induction therapy to treat a 12-year condition of ulcerative colitis (UC). Previously, he was treated with drugs, such as mesalamine, immunomodulators, prednisolone (PSL), and anti-TNFα anti-body, but remission was not maintained. Therefore, we started remission induction therapy with 20 mg/day of tofacitinib (TOF) to inhibit the action of Janus kinase. On the 29th day after TOF administration, he developed a lung abscess with high fever. A chronic bulla was already present in his lung; therefore, the lung abscess was likely formed due to a combination of the bulla being present and the pharmacological effects of TOF. Our report is significant as it highlights the compounding association between TOF and PSL therapy and bulla presence with the rare adverse effect of developing an abscess.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Lizhong Decoction (LZD) is a classical prescription firstly recorded in "Shanghan Lun". It has been used to clinically treat ulcerative colitis (UC) for thousands of years. However, its mechanism is not clear up to now. AIM OF THE STUDY The goal of this study was to assess the amelioration of LZD on dextran sodium sulfate (DSS)-induced colitis in mice and further clarify its mechanism. MATERIALS AND METHODS The ulcerative colitis model induced by DSS was successfully established and applied to evaluate the intervention effect after oral administration of LZD. Furthermore, the expression of key targets in inflammatory signaling pathways and intestinal tight junction proteins were investigated by enzyme-linked immunosorbent assay (ELISA) and quantitative real time polymerase chain reaction (qPCR) analysis. RESULTS The results showed that all doses of LZD could notably improve DSS-induced colon lesions, reduce histological scores, prolong colon length and increase body weight. Colonic inflammation in UC mice was significantly alleviated by inhibiting the activities of myeloperoxidase (MPO) and superoxide dismutase (SOD), reducing the yield of nitric oxide (NO) and inflammatory cytokines such as interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6), and along with promoting the production of anti-inflammatory cytokines such as interleukin-4 (IL-4) and interleukin-10 (IL-10) after LZD treatment. Furthermore, LZD remarkably down-regulated the level of toll-like receptor 4 (TLR4) and nuclear factor-κB (NF-κB) mRNA and up-regulated the expression of tight junction proteins (zonula occluden-1, occludin and claudin-1) in UC mice. CONCLUSION In summary, this study indicated that LZD could notably improve UC symptoms by suppressing inflammation and ameliorating gut barrier, which provided scientific basis for its clinical application in the future.

Abstract
Biological monoclonal antibodies such as infliximab have significantly remodeled inflammatory bowel disease's treatment course. Despite multiple side effects reported with infliximab, this medication has shown to be robust and practical. There is a paucity of cases reporting venous thromboembolism (VTE) occurrence during the treatment with infliximab. Although such an association's exact mechanism is still not precise, we should be aware of the drug thromboembolic aptitude. Close attention should be given to patients who started infliximab infusion for any symptoms of pulmonary embolism or deep vein thrombosis.

Abstract
6-Aminopyridin-3-ol scaffold has shown an excellent anti-inflammatory bowel disease activity. Various analogues with the scaffold were synthesized in pursuit of the diversity of side chains tethering on the C(6)-position. Structure-activity relationship among the analogues was investigated to understand the effects of the side chains and their linkers on their anti-inflammatory activities. In this study, structural modification moved beyond side chains on the C(6)-position and reached to pyridine ring itself. It expedited us to synthesize diverse ring-modified analogues of a representative pyridine-3-ol, 6-acetamido-2,4,5-trimethylpyridin-3-ol (9). In the evaluation of compounds on their inhibitory actions against TNF-α-induced adhesion of monocytic cells to colonic epithelial cells, an in vitro model mimicking colon inflammation, the effects of compounds 9, 17, and 19 were greater than tofacitinib, an orally available anti-colitis drug, and compound 17 showed the greatest activity. In addition, TNF-α-induced angiogenesis, which permits more inflammatory cell migration into inflamed tissues, was significantly blocked by compounds 17 and 19 in a concentration-dependent manner. In the comparison of in vivo therapeutic effects of compounds 9, 17, and 19 on dextran sulfate sodium (DSS)-induced colitis in mice, compound 17 was the most potent and efficacious, and compound 19 was better than compound 9 which showed a similar degree of inhibitory effect to tofacitinib. Taken together, it seems that either the trimethyl system or the hydroxyl group on the pyridinol ring is essential to the activity. This finding might become a new milestone in the development of pyridinol-based anti-inflammatory bowel disease agents.

Abstract
Ulcerative colitis (UC) is an inflammation of the colon that can progress to colorectal cancer if left untreated. No medication completely cures UC and natural products are sources of alternative approaches. This study aimed to determine the anti-inflammatory potential of Phyllanthus nivosus leaf extract and fractions in a rat model of ulcerative colitis and to identify the active ingredients. UC was induced in rats by intra-rectal infusion of 1ml of 4% acetic acid (AA) in normal saline. AA exposed groups of rats were treated with 100 mg/kg bodyweight of methanol extract, hexane, ethyl-acetate and butanol fractions orally for four days. Another group received the standard drug - Dexamethasone and control rats were given distilled water only. Some biochemical changes were evaluated and the active ingredients were identified using Gas Chromatography-Mass Spectrometry (GC-MS) followed by molecular docking against interleukin-1-beta converting enzyme (Caspase-1), beta-2 adrenergic receptor (ADRB2), cyclooxygenase-2 (COX-2) and tumour necrosis factor-alpha (TNF-α). Exposure of rat colon to acetic acid significantly altered (p < 0.05) serum levels of tumour necrosis factor-alpha (TNF-α), interleukin - 6 (IL-6), nitric oxide (NO), lipid peroxidation product (malondialdehyde or MDA), reduced glutathione (GSH); and activities of superoxide dismutase (SOD) and catalase (CAT). These alterations were however restored in the rats treated with P. nivosus leaf with the ethyl-acetate fraction displaying the highest ameliorative activity. GC-MS analysis of the ethyl acetate fraction revealed the presence of 40 compounds which when subjected to molecular docking demonstrated varying degrees of binding affinities for the protein targets. Ethyl iso-allocholate demonstrated the highest binding affinity for caspase-1, cholest-22-ene-21-ol, 3,5-dehydro-6- methoxy-, pivalate for ADRB2 and TNF-α; and alpha-cadinol for COX-2. The anti-inflammatory potential of Phyllanthus nivosus leaf as a natural remedy and as a source of new drugs against ulcerative colitis is validated.

Abstract
Background Tofacitinib is an oral, small molecule Janus kinase inhibitor approved in Japan for the treatment of ulcerative colitis (UC). Differences in the safety profile of tofacitinib in Japanese patients versus the global population, such as a higher risk of herpes zoster, have been reported. Objectives We conducted post hoc analyses of tofacitinib treatment in Japanese patients with moderate-to-severe UC in two global phase III studies. Methods In OCTAVE Induction 1 (NCT01465763), 62 patients were randomized to placebo or tofacitinib 10 mg twice daily (b.i.d.). In OCTAVE Sustain (NCT01458574), 39 patients with clinical response in OCTAVE Induction 1 were re-randomized to placebo, tofacitinib 5 mg, or 10 mg b.i.d. Efficacy endpoints included: remission (primary endpoint; total Mayo score ≤2; no individual subscore >1; rectal bleeding subscore 0); mucosal healing (Mayo endoscopic subscore ≤1); clinical response (≥30% and ≥3-point decrease from induction study baseline total Mayo score; decrease in rectal bleeding subscore ≥1 or absolute subscore ≤1). Adverse events (AEs) and clinical laboratory parameters were recorded. Results At week 8 of OCTAVE Induction 1, 22.4% of patients achieved remission with tofacitinib (placebo, 7.7%). At week 52 of OCTAVE Sustain, 31.3% and 66.7% of patients receiving tofacitinib 5 and 10 mg b.i.d., respectively, achieved remission (placebo, 9.1%). The occurrence of AEs or serious AEs in Japanese patients was generally similar to that in the global study population, with no new or unexpected safety risks observed. Conclusions Although patient numbers were small, tofacitinib demonstrated numerically greater efficacy versus placebo among Japanese patients in OCTAVE Induction 1 and OCTAVE Sustain, with a safety profile consistent with that of the global study population.

Abstract
Autoimmune hepatitis (AIH) is a cause of chronic, immune-mediated liver injury which without treatment may progress to end-stage liver disease. The disease state, characterized by elevations in liver enzymes, autoantibodies, and interface hepatitis on histology, has been noted to be induced by a wide range of insults. Medications, most commonly minocycline and nitrofurantoin, have long been established as potential inducers of AIH. Recently, biologics, powerful immune-modulators, have also been reported to induce AIH. We conclude that there is an association between administration of biologics in the development of AIH, and whether the relationship is causal will require appropriate studies in the future.

Abstract
Background The aim of the study was to assess the efficacy and safety of tofacitinib and its impact on quality of life in patients with moderate-to-severe ulcerative colitis. Methods We conducted a systematic review and meta-analysis of randomized controlled trials comparing tofacitinib with placebo or any active comparator. We searched Medline, Embase, the Cochrane Library and gray literature for articles published up to May 2017. We synthesized data using a fixed-effect model. We conducted subgroup analysis based on prior exposure to anti-tumor necrosis factor (TNF). We summarized the strength of evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Results We included three trials with 1220 participants. Compared with placebo, tofacitinib was effective in inducing clinical remission (odds ratio [OR] 3.84, 95% confidence interval [CI] 2.29-6.44, I2: 41%, GRADE: moderate), clinical response (OR 2.95, 95%CI 2.21-3.95, I2: 0%, GRADE: high), mucosal healing (OR 2.70, 95%CI 1.81-4.03, I2: 0%, GRADE: high). Tofacitinib was effective in both anti-TNF-naïve and -experienced patients. Tofacitinib had a favorable effect on quality of life. There were no significant differences in the safety profile in terms of the incidence of any or serious adverse events compared to placebo. The risk for infections was increased (OR 1.51, 95%CI 1.05-2.19, I2: 0%, GRADE: moderate), but the incidence of serious infections did not differ between tofacitinib and placebo. Conclusion In patients with moderate-to-severe ulcerative colitis, short-term treatment with tofacitinib is effective for induction of remission and improvement of quality of life.

Abstract
Ulcerative colitis (UC) is a chronic, idiopathic, inflammatory bowel disease of the colon. T cell responses have been associated with the pathology of UC. Andrographis paniculata (AP) extract has been previously reported as an effective treatment of UC. The present study aimed to explore the effects of andrographolide, the primary active component of AP, on the T cell responses of patients with UC. Peripheral blood mononuclear cells (PBMCs) were isolated from patients with UC and treated with various concentrations of andrographolide (0, 10, 20 and 30 µg/ml). Andrographolide decreased interferon γ, interleukin (IL)‑23 and IL‑17A, however it increased IL‑4 in a dose‑dependent manner, as indicated by ELISA assay. Andrographolide treatment resulted in a decreased percentage of T helper (Th)1 and Th17 cells and an increased proportion of Th2 cells, as demonstrated by flow cytometry analysis. T‑bet (a Th1‑specific transcription factor) and RAR‑related orphan receptor γt (key transcription factor of Th17 cells) expression was decreased, but GATA‑3 (Th2 lineage‑specific transcription factor) expression was increased following andrographolide treatment as indicated by western blot analysis. These results demonstrated the inhibitory effects on Th1/Th17 responses and the promoting effects on Th2 responses of andrographolide. Experiments on IL‑23‑treated PBMCs from healthy donors revealed similar effects of andrographolide on Th1/Th2/Th17 responses. In summary, these results suggest that andrographolide may be an effective candidate for the treatment of IL‑23‑mediated diseases.

Abstract
BACKGROUND Biologic therapy has revolutionized the management of refractory chronic autoimmune and auto-inflammatory disease, as well as several malignancies, providing rapid symptomatic relief and/or disease remission. Patients receiving biologic therapies have an improved quality of life, facilitating travel to exotic destinations and potentially placing them at risk of a range of infections. For each biologic agent, we review associated travel-related infection risk and expected travel vaccine response and effectiveness. METHODS A PUBMED search [vaccination OR vaccine] AND/OR ['specific vaccine'] AND/OR [immunology OR immune response OR response] AND [biologic OR biological OR biologic agent] was performed. A review of the literature was performed in order to develop recommendations on vaccination for patients in receipt of biologic therapy travelling to high-risk travel destinations. RESULTS There is a paucity of literature in this area, however, it is apparent that travel-related infection risk is increased in patients on biologic therapy and when illness occurs they are at a higher risk of complication and hospitalization. Patients in receipt of biologic agents are deemed as having a high level of immunosuppression-live vaccines, including the yellow fever vaccine, are contraindicated. Inactivated vaccines are considered safe; however, vaccine response can be attenuated by the patient's biologic therapy, thereby resulting in reduced vaccine effectiveness and protection. CONCLUSIONS Best practice requires a collaborative approach between the patient's primary healthcare physician, relevant specialist and travel medicine expert, who should all be familiar with the immunosuppressive and immunomodulatory effects resulting from the biologic therapies. Timing of vaccines should be carefully planned, and if possible, vaccination provided well before established immunosuppression.

Abstract
We aim to investigate the role of microRNA-495 (miR-495) in the intestinal mucosal barrier by indirectly targeting signal transducer and activator of transcription 3 (STAT3) through the Janus kinase-signal transducer and activator of transcription (JAK)/STAT3 signaling pathway in a mouse model of ulcerative colitis (UC). BALB/c mice were selected for establishing mice model of UC, and intestinal tissues of normal and UC mice were collected. ELISA was conducted for detecting levels of TNF-α, IL-6, IFN-γ and IL-10. The levels of SOD, MPO, MDA and NO were tested in the intestinal tissues. Dual luciferase reporter gene assay was applied to determine whether miR-495 directly targets STAT3. Cells were cultured, transfected and assigned into: normal group, blank group, NC group, miR-495 mimic group, miR-495 inhibitor group, siRNA-STAT3 group and miR-495 inhibitor+siRNA-STAT3 group. MTT was used for testing cell proliferation, flow cytometry for cell cycle and apoptosis. Northern blotting and Western blotting were performed to detect miR-495 expression and expressions of STAT3, JAK and Claudin-1. Results show that the UC group had higher expression levels of TNF-α, IL-6, IFN-γ, MPO, MDA, NO, STAT3 and JAK and lower expression levels of IL-10, SOD, miR-495 and Claudin-1, compared to the normal group. Dual luciferase reporter gene assay confirmed that STAT3 was the target gene of miR-495. The miR-495 mimic and siRNA-STAT3 groups had higher expressions of Claudin-1, higher cell proliferation and increased amount of cells in S phase, but lower expressions of STAT3 and JAK, decreased amount of cells in G0/G1 phase and cell apoptotic rate compared with the blank, NC groups. We also found that the miR-495 inhibitor+siRNA-STAT3 group had reduced miR-495 expression. No significant differences were found in mRNA and protein expressions of STAT3, JAK and Claudin-1, cell proliferation, apoptosis and cycle amongst the miR-495 inhibitor+siRNA-STAT3 groups. Our study provides evidence that miR-495 improves the intestinal mucosal barrier function by targeting STAT3 through inhibiting the JAK/STAT3 signaling pathway in UC mice.

Abstract
OBJECTIVE To investigate the anti-inflammatory effects of decursin and decursinol angelate-rich Angelica gigas Nakai (AGNE) on dextran sulfate sodium (DSS)-induced murine ulcerative colitis (UC). METHODS The therapeutic effect of an AGNE was analyzed in a mouse model of UC induced by DSS. Disease activity index values were measured by clinical signs such as a weight loss, stool consistency, rectal bleeding and colon length. A histological analysis was performed using hematoxylin and eosin staining. Key inflammatory cytokines and mediators including IL-6, TNF-α, PGE2, COX-2 and HIF-1α were assayed by enzyme-linked immunosorbent assay or western blotting. RESULTS Treatment with the AGNE at 10, 20, and 40 mg/kg alleviated weight loss, decreased disease activity index scores, and reduced colon shortening in mice with DSS-induced UC. AGNE inhibited the production of IL-6 and TNF-α in serum and colon tissue. Moreover, AGNE suppressed the increased expression of COX-2 and HIF-1α and the increased production of PGE2 in colon tissue were observed in mice with DSS-induced UC. Additionally, histological damage was also alleviated by AGNE treatment. CONCLUSIONS The findings of this study verified that AGNE significantly improves clinical symptoms and reduces the activity of various inflammatory mediators. These results indicate the AGNE has the therapeutic potential in mice with DSS-induced UC.

Abstract
Ulcerative colitis (UC) is a recurrent, chronic intestinal disease. Available treatments for UC are poor effective and/or cause severe adverse events. X-box binding protein 1 (XBP1) and nuclear factor-κB (NF-κB) have been reported to play important roles in UC. Specifically, deletion or downregulation of XBP1 leads to spontaneous enteritis and results in imbalanced secretion of NF-κB and other proinflammatory cytokines. (±)-8-acetonyl-dihydrocoptisine, i.e., (±)-8-ADC, is a monomer semi-synthesized from coptisine. In vitro, (±)-8-ADC activated the transcriptional activity of XBP1, inhibited expression of NF-κB, and reduced production of proinflammatory cytokines, such as tumor necrosis factor alpha (TNF-α) and interleukin-1 beta (IL-1β), in lipopolysaccharide-stimulated IEC6 cells. Therefore, silencing XBP1 would reduce the inhibition effect of (±)-8-ADC on NF-κB expression and the cytokines secretion in vitro. In a dextran sulfate sodium-induced colitis mouse model, oral administration of (±)-8-ADC ameliorated weight loss and colon contracture, and decreased the average disease activity index score and pathological damage. Simultaneously, (±)-8-ADC also increased XBP1 expression, and decreased NF-κB expression and secretion of myeloperoxidase, TNF-α, IL-6 and IL-1β in the colon. Therefore, (±)-8-ADC may ameliorate UC via the XBP1-NF-κB pathway and should be considered as a therapeutic candidate for UC.

Abstract
The effects of indigo naturalis (IN), which is a traditional Chinese herbal formulation, have been clinically demonstrated in treating refractory ulcerative colitis (UC). The present study aimed to verify the effects and mechanisms of IN in experimental UC rats. A total of 48 male Sprague-Dawley rats were randomly divided into six groups: Chow, model, high-dose IN, medium-dose IN, low-dose IN and mesalazine (a bowel-specific aminosalicylate drug) groups. The models were administered 3.5% dextran sodium sulphate solution for 7 days. The treatment groups were administered IN or mesalazine and then sacrificed and sampled on day 8. Disease activity index (DAI), histological damage score (HDS) and myeloperoxidase (MPO) activity were used to evaluate the severity of UC. Colon and serum cytokines were detected using liquid-phase chip technology and the expression of occludin protein in colonic mucosa was assessed by immunohistochemistry and western blot analysis. The results indicated that the oral administration of IN may reduce DAI, HDS and MPO activity. IN also reduced the expression of inflammatory cytokines and increased the expression of colonic mucosal repair-related cytokines and occludin protein. These results highlight the potential of IN as a therapeutic agent for treating UC through its action of inflammation control and colonic mucosal damage repair.

Abstract
The Janus kinase/signal transduction and activator of transcription (JAK-STAT) signaling pathway is implicated in the pathogenesis of inflammatory and autoimmune diseases including rheumatoid arthritis, psoriasis, and inflammatory bowel disease. Many cytokines involved in the pathogenesis of autoimmune and inflammatory diseases use JAKs and STATs to transduce intracellular signals. Mutations in JAK and STAT genes cause a number of immunodeficiency syndromes, and polymorphisms in these genes are associated with autoimmune diseases. The success of small-molecule JAK inhibitors (Jakinibs) in the treatment of rheumatologic disease demonstrates that intracellular signaling pathways can be targeted therapeutically to treat autoimmunity. Tofacitinib, the first rheumatologic Jakinib, is US Food and Drug Administration (FDA) approved for rheumatoid arthritis and is currently under investigation for other autoimmune diseases. Many other Jakinibs are in preclinical development or in various phases of clinical trials. This review describes the JAK-STAT pathway, outlines its role in autoimmunity, and explains the rationale/pre-clinical evidence for targeting JAK-STAT signaling. The safety and clinical efficacy of the Jakinibs are reviewed, starting with the FDA-approved Jakinib tofacitinib, and continuing on to next-generation Jakinibs. Recent and ongoing studies are emphasized, with a focus on emerging indications for JAK inhibition and novel mechanisms of JAK-STAT signaling blockade.

Abstract
The incidence of inflammatory bowel disease (IBD) has increased steadily worldwide, both in adult and in children; approximately 25% of IBD patients are diagnosed before the age of 18. The natural history of IBD is usually more severe in children than in adults, and can be associated with linear growth impairment, delayed puberty onset, reduced bone mass index, malnutrition, and the need for surgery. Biological therapies, especially blocking tumor necrosis factor-α (TNFα), have radically modified the treatment strategies and disease course of IBD in children. In particular, drugs such as Infliximab and Adalimumab are routinely used in the treatment of pediatric IBD. The role of Infliximab and Adalimumab in the management of pediatric IBD has been recently updated in the Consensus guidelines of ECCO/ESPGHAN. Data regarding short-term and long-term efficacy and safety of these drugs in children, and the effects of "top-down" and "step-up" strategies, are lacking. In this paper, the authors will review current indications, efficacy, and safety of biological therapy in pediatric IBD patients, evaluating all articles published after ECCO/ESPGHAN guidelines publication. The authors carried out a systematic search through MEDLINE through PubMed (http://www.ncbi.nlm.nih.gov/pubmed/) Embase, CINAHL, Cochrane Library, and gray literature, from January 2013 to January 2016. Anti-TNFα has been shown to be effective and safe to maintain remission and to achieve mucosal healing. Multicenter trials based on large sample size cohorts are needed to better clarify long-term efficacy of anti-TNFα and the real incidence of treatment-related complications in pediatric IBD.

Abstract
Psoriasis and the spectrum of inflammatory bowel diseases (IBD) are chronic, inflammatory, organotropic conditions. The epidemiologic coexistence of these diseases is corroborated by findings at the level of disease, biogeography, and intrafamilial and intrapatient coincidence. The identification of shared susceptibility loci and DNA polymorphisms has confirmed this correlation at a genetic level. The pathogenesis of both diseases implicates the innate and adaptive segments of the immune system. Increased permeability of the epidermal barrier in skin and intestine underlies the augmented interaction of allergens and pathogens with inflammatory receptors of immune cells. The immune response between psoriasis and IBD is similar and comprises phagocytic, dendritic, and natural killer cell, along with a milieu of cytokines and antimicrobial peptides that stimulate T-cells. The interplay between dendritic cells and Th17 cells appears to be the core dysregulated immune pathway in all these conditions. The distinct similarities in the pathogenesis are also reflected in the wide overlapping of their therapeutic approaches. Small-molecule pharmacologic immunomodulators have been applied, and more recently, biologic treatments that target proinflammatory interleukins have been introduced or are currently being evaluated. However, the fact that some treatments are quite selective for either skin or gut conditions also highlights their crucial pathophysiologic differences. In the present review, a comprehensive comparison of risk factors, pathogenesis links, and therapeutic strategies for psoriasis and IBD is presented. Specific emphasis is placed on the role of the immune cell species and inflammatory mediators participating in the pathogenesis of these diseases.

Abstract
Ulcerative colitis (UC) is a chronic inflammatory bowel disease of unknown etiology. Current common medical treatments for UC are mainly composed of anti-inflammatory and immune-regulatory medications, such as aminosalicylic acid and glucocorticoids. New biological agents as well as probiotics have also emerged as recommended drugs for clinical treatment of UC. The advances in research and the rapid development of pharmaceutical technology have resulted in new progress in treatments for UC. This article will review recent progress in drug therapy of ulcerative colitis.

Abstract
Biologics have revolutionized the therapeutic approach in inflammatory bowel disease (IBD). Anti-tumor necrosis factor (anti-TNF) agents infliximab and adalimumab currently constitute the major biological therapy in IBD. Additional anti-TNFs such as golimumab and other new biologics are currently being developed for both anti-TNF-naïve and -resistant patients. These include anti-integrins (vedolizumab and etrolizumab), a JAK inhibitor (tofacitinib) and an anti-anti-interleukin (IL)-23 and IL-12 antibody (ustekinumab), among additional drugs in development. The following review discusses the indications, efficacy and safety issues for these novel medications.

Abstract
Colorectal cancer (CRC) is one of the most common malignancies and is associated closely with inflammation before and after development. Macrophages promote colitis and colitis-associated CRC. M1 macrophages contribute to colitis directly through the production of proinflammatory cytokines and through activation of proinflammatory immune cell phenotypes. In cancer, both M1 and M2 macrophages participate in tumor development and progression through cytokine production, changes in cell signaling and activation of T cells. We have identified the mitogen-activated protein kinase-activated protein kinase 2 (MK2) as a regulator of macrophages during colitis-associated CRC (CAC). MK2 is a proinflammatory kinase that promotes production of IL-1α, IL-1β, IL-6 and TNF-α. MK2−/− mice have decreases in macrophages, macrophage-associated chemokines, and proinflammatory cytokines. Most significantly, MK2−/− mice do not develop neoplasms in an inflammatory model of CRC. However, addition of MK2+/+ macrophages to MK2−/− mice increases production of proinflammatory cytokines. In wild type mice, both cytokines and tumor burdens increase upon addition of additional macrophages. These data support the importance of MK2 in macrophage regulation during inflammation-associated CRC.
