Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Licorice is a medicinal herb with a 2000-year history of applications in traditional Chinese medicine. Isoliquiritigenin (ISL) is a bioactive chalcone compound isolated from licorice. It has attracted increasing attention in recent years due to its excellent anti-inflammatory activity. AIM OF THE STUDY This study is to provide a comprehensive summary of the anti-inflammatory activity of ISL and the underlying molecular mechanisms, and discuss new insights for its potential clinical applications as an anti-inflammation agent. MATERIALS AND METHODS We examined literatures published in the past twenty years from PubMed, Research Gate, Web of Science, Google Scholar, and SciFinder, with single or combined key words of "isoliquiritigenin", "inflammation", and "anti-inflammatory". RESULTS ISL elicits its anti-inflammatory activity by mediating various cellular processes. It inhibits the upstream of the nuclear factor kappa B (NF-κB) pathway and activates the nuclear factor erythroid related factor 2 (Nrf2) pathway. In addition, it suppresses the NOD-like receptor protein 3 (NLRP3) pathway and restrains the mitogen-activated protein kinase (MAPK) pathway. CONCLUSIONS Current studies indicate a great therapeutical potential of ISL as a drug candidate for treatment of inflammation-associated diseases. However, the pharmacokinetics, biosafety, and bioavailability of ISL remain to be further investigated.

Mechanisms of Qingyi Decoction in Severe Acute Pancreatitis-Associated Acute Lung Injury via Gut Microbiota: Targeting the Short-Chain Fatty Acids-Mediated AMPK/NF-κB/NLRP3 Pathway. Microbiol Spectr 2023; 11:e0366422. [PMID: 37338348 PMCID: PMC10434154 DOI: 10.1128/spectrum.03664-22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2022] [Accepted: 05/24/2023] [Indexed: 06/21/2023] Open
Abstract
The pivotal roles of gut microbiota in severe acute pancreatitis-associated acute lung injury (SAP-ALI) are increasingly revealed, and recent discoveries in the gut-lung axis have provided potential approaches for treating SAP-ALI. Qingyi decoction (QYD), a traditional Chinese medicine (TCM), is commonly used in clinical to treat SAP-ALI. However, the underlying mechanisms remain to be fully elucidated. Herein, by using a caerulein plus lipopolysaccharide (LPS)-induced SAP-ALI mice model and antibiotics (Abx) cocktail-induced pseudogermfree mice model, we tried to uncover the roles of the gut microbiota by administration of QYD and explored its possible mechanisms. Immunohistochemical results showed that the severity of SAP-ALI and intestinal barrier functions could be affected by the relative depletion of intestinal bacteria. The composition of gut microbiota was partially recovered after QYD treatment with decreased Firmicutes/Bacteroidetes ratio and increased relative abundance in short-chain fatty acids (SCFAs)-producing bacteria. Correspondingly increased levels of SCFAs (especially propionate and butyrate) in feces, gut, serum, and lungs were observed, generally consistent with changes in microbes. Western-blot analysis and RT-qPCR results indicated that the AMPK/NF-κB/NLRP3 signaling pathway was activated after oral administration of QYD, which was found to be possibly related to the regulatory effects on SCFAs in the intestine and lungs. In conclusion, our study provides new insights into treating SAP-ALI through modulating the gut microbiota and has prospective practical value for clinical use in the future. IMPORTANCE Gut microbiota affects the severity of SAP-ALI and intestinal barrier function. During SAP, a significant increase in the relative abundance of gut pathogens (Escherichia, Enterococcus, Enterobacter, Peptostreptococcus, Helicobacter) was observed. At the same time, QYD treatment decreased pathogenic bacteria and increased the relative abundance of SCFAs-producing bacteria (Bacteroides, Roseburia, Parabacteroides, Prevotella, Akkermansia). In addition, The AMPK/NF-κB/NLRP3 pathway mediated by SCFAs along the gut-lung axis may play an essential role in preventing the pathogenesis of SAP-ALI, which allows for reduced systemic inflammation and restoration of the intestinal barrier.

Flavonoids in Amomum tsaoko Crevost et Lemarie Ameliorate Loperamide-Induced Constipation in Mice by Regulating Gut Microbiota and Related Metabolites. Int J Mol Sci 2023; 24:ijms24087191. [PMID: 37108354 PMCID: PMC10139007 DOI: 10.3390/ijms24087191] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2023] [Revised: 04/04/2023] [Accepted: 04/06/2023] [Indexed: 04/29/2023] Open
Abstract
Amomum tsaoko (AT) is a dietary botanical with laxative properties; however, the active ingredients and mechanisms are still unclear. The active fraction of AT aqueous extract (ATAE) for promoting defecation in slow transit constipation mice is the ethanol-soluble part (ATES). The total flavonoids of ATES (ATTF) were the main active component. ATTF significantly increased the abundance of Lactobacillus and Bacillus and reduced the dominant commensals, such as Lachnospiraceae, thereby changing the gut microbiota structure and composition. Meanwhile, ATTF changed the gut metabolites mainly enriched in pathways such as the serotonergic synapse. In addition, ATTF increased the serum serotonin (5-HT) content and mRNA expression of 5-hydroxytryptamine receptor 2A (5-HT2A), Phospholipase A2 (PLA2), and Cyclooxygenase-2 (COX2), which are involved in the serotonergic synaptic pathway. ATTF increased Transient receptor potential A1 (TRPA1), which promotes the release of 5-HT, and Myosin light chain 3(MLC3), which promotes smooth muscle motility. Notably, we established a network between gut microbiota, gut metabolites, and host parameters. The dominant gut microbiota Lactobacillus and Bacillus, prostaglandin J2 (PGJ2) and laxative phenotypes showed the most significant associations. The above results suggest that ATTF may relieve constipation by regulating the gut microbiota and serotonergic synaptic pathway and has great potential for laxative drug development in the future.

Abstract
The aim of this study was to investigate the effect of naringin on lipopolysaccharide (LPS)-induced jejunal barrier function in mice. Forty-five 3-week-old healthy male Balb/c mice with similar body weights were randomly divided into control group, LPS group, LPS + naringin group, with 15 mice in each treatment group. The mice were intraperitoneally injected with the same dose of saline or LPS (10 mg per kg BW) at 43 d. The blood samples, liver and jejunal tissues were collected after 3 h of injection. The results showed that LPS significantly increased the serum diamine oxidase (DAO) activity, D-lactate (D-LA) concentration, and malondialdehyde (MDA) content in liver and jejunum, while decreased the activities of superoxide dismutase (SOD), glutathione peroxidase (Gpx) and catalase (CAT) in liver and jejunum. The LPS treatment caused an increase in the crypt depth and a decrease in the villus height and the ratio of villus height to crypt depth (V/C) of the jejunum. In addition, the LPS treatment significantly increased the mRNA expressions of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), IL-6, toll-like receptor 4 (TLR4), p38-mitogen-activated protein kinase (p38 MAPK), nuclear factor-κB (NF-κB) and kelch-like ECH-associated protein 1 (Keap1), while decreased mRNA expressions of zonula occludens 1 (ZO-1), occludin, claudin, mucin 2 (MUC2) and junctional adhesion molecule 2 (JAM2), Gpx, SOD1, GST, CAT and nuclear factor-erythroid 2-related factor 2 (Nrf2). However, the naringin treatment mitigated these effects induced by LPS. Taken together, our findings suggested that naringin attenuates LPS-induced intestinal barrier damage by inhibiting inflammatory factors and improving antioxidant function and intestinal tight junction, which might be mediated by activating the Nrf2 signaling and suppressing the TLR4/p38 MAPK/NF-κB signaling.

Abstract
The surge of scientific interest in the discovery of Nuclear Factor Erythroid 2 (NFE2)-Related Factor 2 (NRF2)-activating molecules underscores the importance of NRF2 as a therapeutic target especially for oxidative stress. The chemical reactivity and biological activities of several bioactive compounds have been linked to the presence of α,β-unsaturated structural systems. The α,β-unsaturated carbonyl, sulfonyl and sulfinyl functional groups are reportedly the major α,β-unsaturated moieties involved in the activation of the NRF2 signaling pathway. The carbonyl, sulfonyl and sulfinyl groups are generally electron-withdrawing groups, and the presence of the α,β-unsaturated structure qualifies them as suitable electrophiles for Michael addition reaction with nucleophilic thiols of cysteine residues within the proximal negative regulator of NRF2, Kelch-like ECH-associated protein 1 (KEAP1). The physicochemical property such as good lipophilicity of these moieties is also an advantage because it ensures solubility and membrane permeability required for the activation of the cytosolic NRF2/KEAP1 system. This review provides an overview of the reaction mechanism of α,β-unsaturated moiety-bearing compounds with the NRF2/KEAP1 complex, their pharmacological properties, structural activity-relationship and their effect on antioxidant and anti-inflammatory responses. As the first of its kind, this review article offers collective and comprehensive information on NRF2-activators containing α,β-unsaturated moiety with the aim of broadening their therapeutic prospects in a wide range of oxidative stress-related diseases.

Abstract
OBJECTIVE The intestinal barrier injury caused by severe acute pancreatitis (SAP) can induce enterogenous infection, further aggravating the inflammatory reactions and immune responses. This study aimed to test the hypothesis that emodin protects the intestinal function and is involved in the immune response in SAP. METHODS The network pharmacology was established using the Swiss target prediction and pathway enrichment analysis. The SAP mice model was induced by cerulein (50 μg/kg) and lipopolysaccharide (10 mg/kg) hyperstimulation. The pharmacological effect of emodin in treating SAP was evaluated at mRNA and protein levels by various methods. RESULTS The network analysis provided the connectivity between the targets of emodin and the intestinal barrier-associated proteins and predicted the BAX/Bcl-2/caspase 3 signaling pathway. Emodin alleviated the pathological damages to the pancreas and intestine and reduced the high concentrations of serum amylase and cytokines in vivo. Emodin increased the expression of intestinal barrier-related proteins and reversed the changes in the apoptosis-related proteins in the intestine. Simultaneously, emodin regulated the ratio of T helper type 1 (TH1), TH2, TH17, γδ T cells, and interferon γ/interleukin 17 producing γδ T cells. CONCLUSIONS These findings partly verified the mechanism underlying the regulation of the intestinal barrier and immune response by emodin.

Abstract
BACKGROUND Several recent studies have stated that glycyrrhizin and licorice extract are present in most traditional Chinese medicine formulas used against SARS-CoV-2 in China. Significant data are showing that glycyrrhizin and licorice extract have multiple beneficial activities in combating most features of SARS-CoV-2. PURPOSE The aim of current review was to highlight recent progresses in research that showed the evidence of the potential use of glycyrrhizin and licorice extract against COVID-19. METHODOLOGY We have reviewed the information published from 1979 to October 2020. These studies demonstrated the effects , use and safety of glycyrrhizin and icorice extract against viral infections,bacterial infections, inflammatory disorders of lung ( in vitro and in vivo). These studies were collated through online electronic databases research (Academic libraries as PubMed, Scopus, Web of Science and Egyptian Knowledge Bank). RESULTS Pooled effect size of articles provides information about the rationale for using glycyrrhizin and licorice extract to treat COVID-19. Fifty studies demonstrate antiviral activity of glycyrrhizin and licorice extract. The most frequent mechanism of the antiviral activity is due to disrupting viral uptake into the host cells and disrupting the interaction between receptor- binding domain (RBD) of SARS-COV2 and ACE2 in recent articles. Fifty studies indicate that glycyrrhizin and licorice extract have significant antioxidant, anti-inflammatory and immunomodulatory effects. Twenty five studies provide evidence for the protective effect of glycyrrhizin and licorice extract against inflammation-induced acute lung injury and cardiovascular disorders. CONCLUSION The current study showed several evidence regarding the beneficial effects of glycyrrhizin and licorice extract in combating COVID-19. More randomized clinical trials are needed to obtain a precise conclusion.

Luteolin, a dietary flavonoid, has gained increasing interest as an intestinal protectant. This study aimed to evaluate the reparative effect of luteolin against ethanol-induced intestinal barrier damage in a Caco-2 cell monolayer model and the potential mechanisms. Luteolin attenuated ethanol-induced intestinal barrier injury, by increasing transepithelial monolayer resistance (TEER, 27.75 ± 14.75% of the ethanol group, p < 0.01), reducing Lucifer yellow flux (13.21 ± 1.23% of ethanol group, p < 0.01), and upregulating the expression of tight junction (TJ) proteins zonulin occludin-1 (ZO-1), occludin, and claudin-1 (37.963 ± 8.62%, 17.69 ± 7.35%, and 29.40 ± 8.08% of the ethanol group, respectively, p < 0.01). Further mechanistic studies showed that luteolin suppressed myosin light chain 2 (MLC) phosphorylation, myosin light chain kinase (MLCK) activation, nuclear factor kappa-B (NF-κB) nuclear translocation, and mitogen-activated-protein-kinase (MAPK) phosphorylation. Moreover, luteolin also acted as antioxidants indirectly by upregulating antioxidant-responsive-element (ARE) and nuclear factor (erythroid-derived 2)-like 2 (Nrf2) nuclear translocation to relieve ethanol-induced oxidative damage and TJ dysfunction. The results of the study indicate that luteolin may play an effective role in relieving intestinal barrier damage, and this effect is at least partially due to its indirect antioxidant capacity.

Abstract
Introduction:Nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway plays a key role in diverse gene expressions responsible for protection against oxidative stress and xenobiotics. Chalcones with a common chemical scaffold of 1,3-diaryl-2- propen-1-one, are abundantly present in nature with a wide variety of pharmacological properties. This review will discuss the interactions of natural and synthetic chalcones with Nrf2 signaling.Areas covered:Chalcones are reportedly found to activate Nrf2 signaling pathway, expression of Nrf2-regulated antioxidant genes, induce cytoprotective proteins and upregulate multidrug resistance-associated proteins. Chalcones being soft electrophiles are less prone to hostile off-target effects and unlikely to induce carcinogenicity and mutagenicity. Furthermore, their low toxicity, structural diversity, feasibility in structural reorganization and the presence of α,β-unsaturated carbonyl group which makes them suitable drug candidates targeting Nrf2-dependent diseases.Expert opinion:Nrf2-Keap1 signaling pathway plays a central role in redox signaling. However, available therapeutic agents for Nrf2 activation have limited practical applications due to their associated risks, relatively low efficacy and bioavailability. The designing and fabrication of new chemical entities with chalcone scaffold-based Michael acceptor mechanism should be aimed as potential therapeutic Nrf2 activators to target oxidative stress and inflammation-mediated diseases such as atherosclerosis, Parkinson's disease and many more.

Abstract
OBJECTIVES Acute pancreatitis (AP) is a common severe critical illness with a high mortality rate. We aimed to study the effect of vinpocetine (Vinpo) in the treatment of AP because of its anti-inflammatory, antioxidant, and antiapoptotic effects. MATERIALS AND METHODS Thirty two adult male albino Wistar rats were randomized to four groups: control group, Vinpo group (20 mg/kg.P.O.), l-arginine group (two intraperitoneal injections of l-arginine 2.5 g/kg, 1 h apart), and Vinpo + L-arginine group. Vinpo administration was once daily for 7 consecutive days and started 1 h later after l-arginine administration. We measured serum enzyme biomarkers (lipase and amylase), levels of pancreatic malondialdehyde (MDA), total antioxidant capacity (TAC), reduced glutathione (GSH), total sulfhydryl (T-SH), total nitrite/nitrate (NOx), Interluken-6 (IL-6), tumor necrosis factor-alpha (TNF-α), Nuclear factor (erythroid-derived 2)-like 2 (Nrf2), Sirtuin type 1 (Sirt1), and caspase-3 activity. Furthermore; histological changes, anti-insulin, and inducible nitric oxide synthase (iNOS) immuno-expressions were examined. RESULTS l-arginine group displayed AP as manifested by a significant increase in serum lipase and amylase, MDA, NOx, IL-6, TNF-α, caspase-3 with iNOS immuno-expression. Histological changes indicating marked pancreatic injury were observed together with a significant decrease in TAC, GSH, T-SH, Nrf2, Sirt1 levels, and anti-insulin immuno-expression. Vinpo showed a significant amelioration in all parameters. CONCLUSION Vinpo possesses potent ameliorative effects against AP by decreasing oxidative stress, inflammatory process, and apoptosis through regulation of the Sirt1/Nrf2/TNF-α pathway.

Abstract
Severe acute pancreatitis (SAP) is a non-bacterial inflammatory disease that clinically causes a very high rate of mortality. Dihydrokaempferol (DHK) is a natural flavonoid extracted from Bauhinia championii. Our research aimed to establish the treatment function of DHK on SAP-induced pancreas injury and delve into its potential mechanism. In this study, SAP was induced by caerulein (CER) and Lipopolysaccharide (LPS). DHK was administered orally at different doses of 20, 40, or 80 mg/kg. Results from serum amylase/lipase, pancreas hematoxylin-eosin staining technique, pancreas malondialdehyde (MDA), glutathione (GSH), and reactive oxygen species (ROS) showed the therapeutic effect of DHK in a mice SAP model. MTT revealed DHK alleviated CER + LPS induced cytotoxicity in a dose-dependent manner in the pancreatic acinar cells of mice. Next, we verified DHK suppressed the level of Keap1 and promoted transcriptional activation of nuclear Nrf2 in the presence of CER + LPS. The molecular docking study suggested that there is a potential interaction between DHK and Keap1. To further look at the role of Keap1 using in vitro and in vivo models, Keap1 overexpression adenovirus (ad-Keap1) was performed. The results revealed that ad-Keap1suppressed the nuclear translocation of Nrf2 which is enhanced by DHK, and suppressed the antioxidative functionality of DHK both in mice and cell models. Collectively, this research demonstrated that DHK bettered the SAP induced pancreas injury by regulating the Keap1/Nrf2 pathway and regulating oxidative stress injury.

Abstract
Acute pancreatitis is a severe abdominal pathology often associated with several complications including gut dysfunction. Oxidative stress is one of the most important pathways involved in this pathology. Hydroxytyrosol (HT), a phenolic compound obtained from olive oil, has shown anti-inflammatory and antioxidant properties. We evaluated the effects of HT administration on pancreatic and intestinal injury induced by caerulein administration. CD1 female mice were administered caerulein (50 μg/kg) for 10 h. HT treatment (5 mg/kg) was performed 30 min after the first caerulein injection and for two consecutive hours afterwards. One hour after the last caerulein injection, mice were sacrificed and serum, colon and pancreatic tissue samples were collected. HT was able to reduce the serum hallmarks of pancreatitis (amylase and lipase), histological damage score in both pancreas and colon tissue, inflammatory cells recruitment (mast cells) in both injured tissues, intrapancreatic trypsin activity and overexpression of the adhesion molecules (Intercellular Adhesion Molecule-1 (ICAM-1) and P-selectin) in colon. Additionally, HT reduced cytokine (interleukin 1 beta (IL- 1β), interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF-α)) levels in serum, pancreas and colon tissue and chemokine release (monocyte chemotactic protein-1 (MCP1/CCL2)) in pancreas and colon tissue. HT decreased lipid peroxidation and oxidative stress (superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione reductase (GR) and glutathione S-transferase (GST) activity) by enhancing the nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase 1 (HO-1) in both injured tissues. Moreover, HT preserved intestinal barrier integrity, as shown by the diamine oxidase (DAO) serum levels and tight junction (zonula occludens (ZO) and occludin) expression in pancreas and colon. Our findings demonstrated that HT would be an important therapeutic tool against pancreatitis-induced injuries in the pancreas and gut.

Abstract
Pancreatic cancer is a disease with limited therapeutic options. Resistance to chemotherapies poses a significant clinical challenge for patients with pancreatic cancer and contributes to a high rate of recurrence. Oncogenic KRAS, a critical driver of pancreatic cancer, promotes metabolic reprogramming and upregulates NRF2, a master regulator of the antioxidant network. Here, we show that NRF2 contributed to chemoresistance and was associated with a poor prognosis in patients with pancreatic cancer. NRF2 activation metabolically rewired and elevated pathways involved in glutamine metabolism. This curbed chemoresistance in KRAS-mutant pancreatic cancers. In addition, manipulating glutamine metabolism restrained the assembly of stress granules, an indicator of chemoresistance. Glutaminase inhibitors sensitized chemoresistant pancreatic cancer cells to gemcitabine, thereby improving the effectiveness of chemotherapy. This therapeutic approach holds promise as a novel therapy for patients with pancreatic cancer harboring KRAS mutation. SIGNIFICANCE: These findings illuminate the mechanistic features of KRAS-mediated chemoresistance and provide a rationale for exploiting metabolic reprogramming in pancreatic cancer cells to confer therapeutic opportunities that could be translated into clinical trials.

Tanshinone IIA Protects against Acute Pancreatitis in Mice by Inhibiting Oxidative Stress via the Nrf2/ROS Pathway. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2020; 2020:5390482.

Abstract
Background Danshen (Salvia miltiorrhiza Bunge) and its main active component Tanshinone IIA (TSA) are clinically used in China. However, the effects of TSA on acute pancreatitis (AP) and its potential mechanism have not been investigated. In this study, our objective was to investigate the protective effects of TSA against AP via three classic mouse models. Methods Mouse models of AP were established by caerulein, sodium taurocholate, and L-arginine, separately. Pancreatic and pulmonary histopathological characteristics and serum amylase and lipase levels were evaluated, and changes in oxidative stress injury and the ultrastructure of acinar cells were observed. The reactive oxygen species (ROS) inhibitor N-Acetylcysteine (NAC) and nuclear factor erythroid 2-related factor 2 (Nrf2) knockout mice were applied to clarify the protective mechanism of the drug. Results In the caerulein-induced AP model, TSA administration reduced serum amylase and lipase levels and ameliorated the histopathological manifestations of AP in pancreatic tissue. Additionally, TSA appreciably decreased ROS release, protected the structures of mitochondria and the endoplasmic reticulum, and increased the protein expression of Nrf2 and heme oxygenase 1 of pancreatic tissue. In addition, the protective effects of TSA against AP were counteracted by blocking the oxidative stress (NAC administration and Nrf2 knockout in mice). Furthermore, we found that TSA protects pancreatic tissue from damage and pancreatitis-associated lung injury in two additional mouse models induced by sodium taurocholate and by L-arginine. Conclusion Our data confirmed the protective effects of TSA against AP in mice by inhibiting oxidative stress via the Nrf2/ROS pathway.

Abstract
BACKGROUND Acute pancreatitis (AP) is often associated with intestinal injury, which in turn exaggerates the progression of AP. Our recent study has shown that a low level of serum irisin, a novel exercise-induced hormone, is associated with poor outcomes in patients with AP and irisin administration protects against experimental AP. However, the role of irisin in intestinal injury in AP has not been evaluated.
AIM To investigate the effect of irisin administration on intestinal injury in experimental AP.
METHODS AP was induced in male adult mice by two hourly intraperitoneal injections of L-arginine. At 2 h after the last injection of L-arginine, irisin (50 or 250 μg/kg body weight) or 1 mL normal saline (vehicle) was administered through intraperitoneal injection. The animals were sacrificed at 72 h after the induction of AP. Intestinal injury, apoptosis, oxidative and endoplasmic reticulum (ER) stress were evaluated.
RESULTS Administration of irisin significantly mitigated intestinal damage, reduced apoptosis, and attenuated oxidative and ER stress in AP mice. In addition, irisin treatment also effectively downregulated serum tumor necrosis factor-alpha and interleukin-6 levels and alleviated injury in the pancreas, liver and lung of AP mice.
CONCLUSION Irisin-mediated multiple physiological events attenuate intestinal injury following an episode of AP. Irisin has a great potential to be further developed as an effective treatment for patients with AP.

Abstract
Patients with severe acute pancreatitis (SAP) represent a substantial challenge to medical practitioners due to the high associated rates of morbidity and mortality and a lack of satisfactory therapeutic outcomes. In a previous study, our group demonstrated that bone marrow-derived mesenchymal stem cells (BMSCs) can ameliorate SAP; however, the mechanisms of action remain to be fully understood. BMSCs were intravenously injected into SAP rats 12 h after experimental induction of SAP using sodium taurocholate (NaT). Histopathological changes and the levels of pro-inflammatory mediators were assessed by hematoxylin and eosin (H&E) staining and ELISA, respectively. Autophagy levels were assessed using qRT-PCR, western blotting, immunohistochemistry, immunofluorescence, and transmission electron microscopy. AR42J cells and human umbilical vein endothelial cells (HUVECs) were administered BMSC-conditioned media (BMSC-CM) after NaT treatment, and cell viability was measured using a Cell Counting Kit-8 (CCK-8) and flow cytometry. In vivo, BMSCs effectively reduced multiple systematic inflammatory responses, suppressed the activation of autophagy, and improved intestinal dysfunction. In vitro, BMSC-CM significantly improved the viability of injured cells, promoted angiogenesis, and decreased autophagy. We therefore propose that the administration of BMSCs alleviates SAP-induced multiple organ injury by inhibiting autophagy.

Abstract
The altered expression and subcellular distribution of tight junction (TJ) proteins, leading to a dysfunctional intestinal barrier, is a key mechanistic feature of inflammatory bowel disease (IBD). Therefore, increasing the integrity of the intestinal barrier by manipulating the TJ may constitute an innovative and effective therapeutic strategy in IBD. In this context, recent studies showed that dietary polyphenols are able to protect the intestinal TJ barrier integrity. Here, using a cellular model of intestinal inflammation, consisting of cytokine-stimulated HT-29 colon epithelial cells, we show that a polyphenolic extract obtained from Portuguese red wine (RWE) decreased the paracellular permeability across the cell monolayer compared with the control cells, even in the presence of pro-inflammatory cytokines. The beneficial effect of RWE was exerted at three complementary levels: (1) by promoting a significant increase of the mRNA of key barrier-forming TJ proteins, including occludin, claudin-5 and zonnula occludens (ZO)-1 above the levels observed in the control cells; (2) by preventing the decrease in the expression of these proteins under inflammatory conditions and (3) by averting the increase in claudin-2 mRNA, a channel-forming TJ protein induced by pro-inflammatory cytokines. Taken together, these results strongly suggest that polyphenols presented and consumed in red wine as a mixture can reinforce and protect the intestinal barrier against inflammatory stimulus by affecting the TJ protein expression and, thus, without the need for purifying individual compounds, might represent a readily available therapeutic intervention against IBD and intestinal inflammation.

Abstract
BACKGROUND Acute pancreatitis is an inflammatory disease of the pancreas associated with high patient morbidity. Lycium barbarum polysaccharide (LBP), a traditional Chinese medicine with an active component extracted from the goji berry, has previously been reported to have anti-inflammatory effects. This study aimed to investigate the effects of LBP in a mouse model of cerulein-induced acute pancreatitis. MATERIAL AND METHODS Acute pancreatitis was induced by intraperitoneal injection of cerulein in C57BL/6 wild-type mice or nuclear factor erythroid-2-related factor 2 (NRF2) gene knockout mice. LBP or normal saline was administrated by gavage once daily for one week before the induction of acute pancreatitis. At 12 hours after the first intraperitoneal injection of cerulein, the mice were euthanized. Blood and pancreatic tissue were sampled for histology and for the measurement of pro-inflammatory cytokines, serum amylase, and lipase. RESULTS In the untreated mouse model of cerulein-induced acute pancreatitis, amylase and lipase levels were increased, and these levels were reduced by LBP treatment when compared with vehicle treatment. In the untreated mouse model, histology of the pancreas showed edema and inflammation, which were reduced in the LBP-treated mice. In the untreated mouse model, increased levels of tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) were found, which were reduced in the LBP-treated mice. NRF2 gene knockout mice with cerulein-induced acute pancreatitis showed reduced anti-inflammatory effects of LBP treatment. LBP increased the expression of NRF2 and heme oxygenase-1 (HO-1). CONCLUSIONS In a mouse model of cerulein-induced acute pancreatitis, LBP reduced inflammation by upregulating NRF2 and HO-1.

Abstract
Inflammation responses and oxidative stress are closely involved in the pathogenesis of arthritis. Ligustrazine (Lig), a natural four methyl which is isolated from Chinese herb ligusticum chuanxiong hort, has been proved significantly anti-inflammation and anti-oxidative stress effects. The present study aimed to evaluate the effect of Lig on inflammation and oxidative stress in Freund's complete adjuvant (FCA)-induced arthritis in rats. The treatment of Lig significantly decreased the hind-paw volume change and alleviated the histopathological changes in sections of rat paws induced by arthritis. Lig also reduced the serum levels of pro-inflammatory cytokines (interleukin [IL]-6, IL-1 beta, and tumor necrosis factor-alpha), increased the activity of superoxide dismutase (SOD) and reduced the concentration of malondialdehyde (MDA). Besides that, the protein expressions of the sirtuin 1 (Sirt1)/nuclear factor kappa B (NF-κB) and nuclear factor (erythroid-derived 2)-like-2 factor (Nrf-2)/heme oxygenase (HO)-1 pathways determined by western bolt further confirmed that Lig effectively inhibited the Sirt1/NF-κB pathway and activated the Nrf-2/HO-1 pathway. Taken together, our results suggest Lig has therapeutic potential for arthritis, which might be via the regulation of Sirt1/NF-κB and Nrf-2/HO-1 pathways.
