Abstract
The enrichment of the social environment during lactation alleviates the stress of weaned piglets. It is significant to understand how the enriched social environment improves the weaning stress of piglets. RNA sequencing (RNA-seq) of colonic mucosa, 16S rRNA sequencing of feces, and short-chain fatty acids (SCFAs) of colonic content were used to determine the effects of social contact during lactation. In this study, thirty litter lactating piglets were divided into intermittent social contact (ISC) group that contacted with neighbors intermittently, continuous social contact (CSC) group that contacted with neighbors starting at day (D) 14 after birth, and control (CON) group in which piglets were kept in their original litter. The piglets were weaned at D35 and regrouped at D36. The colonic mucosal RNA-seq, fecal microbes, and SCFAs of colonic contents of 63-day-old piglets were analyzed. The results of RNA-seq showed that compared with the CON group, the pathways of digestion and absorption of minerals, protein, and vitamins of piglets were changed in the ISC group, whereas the pathways of retinol metabolism and nitrogen metabolism in the colonic mucosal were affected and stimulated the immune response in the CSC group. Compared with the CON group, the abundances of pernicious microorganisms (Desulfovibrio, Pseudomonas, Brevundimonas, etc.) in the CSC group and pernicious microorganisms (Desulfovibrio, Neisseria, Sutterella, etc.) and beneficial bacteria (Bifidobacterium, Megamonas, and Prevotella_9) in the ISC group were significantly higher (p < 0.05). The abundances of proinflammatory bacteria (Coriobacteriaceae_unclassified, Coprococcus_3, and Ruminococcus_2) in the CSC group were significantly increased (p < 0.05), but the abundances of SCFAs producing bacteria (Lachnospiraceae_UCG-010, Parabacteroides, Anaerotruncus, etc.) and those of anti-inflammatory bacteria (Eubacterium, Parabacteroides, Ruminiclostridium_9, and Alloprevotella) were significantly reduced (p < 0.05) in the CSC group. Compared with the CON group, the concentrations of microbial metabolites, acetate, and propionate in the colonic contents were reduced (p < 0.05) in the ISC group, whereas the concentration of acetate was reduced (p < 0.05) in the CSC group. Therefore, both ISC and CSC during lactation affected the composition of fecal microbes and changed the expression of intestinal mucosal genes related to nutrient metabolism and absorption of piglets.

Abstract
PURPOSE To investigate the protective effect and mechanism of rebamipide on NSAIDs associated intestinal injury. METHODS Intestinal injury was induced in Sprague Dawley rats by intragastric administration of diclofenac with rebamipide intervention, and LPS and TAK-242 were given intraperitoneally respectively. The expression of TLR4/NF-κB and the related proteins in the intestinal mucosa were detected. 55 patients taking NSAIDs and diagnosed as NSAIDs associated small intestinal injury were recruited as NSAIDs group. Another 55 patients without NSAIDs and no obvious abnormality in the small bowel served as the control group. RESULTS The macroscopic and histological scores of the small intestinal mucosa in the rebamipide pretreatment group were significantly lower compared to the diclofenac group (p < 0.01). The expressions of Tollip, ZO-1 and Claudin-1 in the diclofenac group were down-regulated compared with that in the control group, while they increased significantly in the rebamipide pretreatment group (p < 0.01). The expressions of TLR4/NF-κBp65, IL-1β, IL-6, IL-8, and TNF-α significantly increased in the model group while they were down-regulated in the rebamipide pretreatment group (p < 0.05). Administration of LPS 1 h after diclofenac aggravated small intestinal damage, and increased expression of IL-1β, IL-6, IL-8 and TNF-α. Administration of rebamipide did not effectively reverse intestinal injury induced by diclofenac and LPS. In contrast, pretreatment with TAK-242 significantly inhibited damage and prevented the increased expression of the cytokines. The expression of TLR4 and NF-κBp65 in the patients with NSAIDs associated intestinal injury was significantly higher than that in the control group (p < 0.01), while the expression of Tollip was decreased (p < 0.01). CONCLUSION Rebamipide effectively alleviated intestinal mucosa injury by probably suppressing the TLR4/NF-κB signaling pathway and the decreasing of ZO-1 and Claudin-1 induced by diclofenac.

Abstract
Objectives: Rebamipide is a protective drug used for gastric mucosal injuries, and it also exerts protective effects for a variety of other tissues. In this study, murine post-traumatic (PT) osteoarthritis (OA) models in vivo and human OA chondrocytes in vitro were used to examine the effects of rebamipide on articular cartilage degeneration.Methods: Male BALB/c mice were used. The knee ligaments were transected in both knees. Mice were injected with rebamipide into the knee joint every week. Human chondrocytes were stimulated with IL-1β, then treated with or without rebamipide. The levels of mRNA expression of COL2A, IL-1β, TNFα, NF-κB, MMP3, MMP13, ADAMTS5, TIMP3, FGF2, and TGFβ were estimated using real-time PCR.Results: Histological scores were significantly better in the rebamipide 1 mg/mL and 10 mg/mL groups than in the control group. Rebamipide up-regulated the mRNA expressions of COL2A, TIMP3, TGFβ, and FGF2 in chondrocytes and down-regulated IL-1β, TNFα, NF-κB, MMP3, MMP13, and ADAMTS5.Conclusion: Intra-articular injection of rebamipide prevents articular cartilage degeneration for 6 weeks in murine models of OA in vivo. Rebamipide down-regulates inflammatory cytokines and catabolic factors and up-regulates anabolic factors in human chondrocytes in vitro. Rebamipide could be an important treatment for prevention of articular cartilage degeneration.

Abstract
One mechanism by which non-steroidal anti-inflammatory drugs (NSAIDs) cause intestinal injury is by inducing matrix metalloproteinases (MMPs) that degrade and remodel the extracellular matrix. In addition to the intestinal mucosa, MMPs are expressed in the skin and can be activated by mast cell-secreted tryptase. We therefore investigated whether intestinal injury resulting from treatment with the NSAID indomethacin induced MMPs in the skin of mice and caused an associated disruption of skin function. Hairless mice and mast cell-deficient mice were administered indomethacin, after which damage to the jejuna and skin was assessed with immunohistochemistry and Western blotting. The plasma concentration of inflammatory mediators was assessed to evaluate potential pathways for signalling skin disruption in response to intestinal injury. In hairless mice with intestinal injury, transepidermal water loss (TEWL) was higher and skin hydration was lower than in control mice. The expression levels of mast cells, tryptase, MMP-1 and MMP-9 were also increased, with concurrent degradation of types I and IV collagen. In contrast, no changes in skin TEWL or skin hydration were observed in mast cell-deficient mice with indomethacin-induced intestinal injury. In all mice evaluated, the plasma concentrations of IgE, IgA, histamine and TNF-α were increased in response to indomethacin treatment. Skin disruption was strongly associated with indomethacin-induced small intestinal injury, and the activation of mast cells and induction of tryptase, MMP-1 and MMP-9 are critical to this association.

Abstract
Recent advances in diagnostic technologies have revealed that nonsteroidal anti-inflammatory drugs (NSAIDs) can cause serious mucosal injury in the upper and lower gastrointestinal tract (including the small intestine). A drug to treat NSAID-induced small-intestinal injury (SII) is lacking. Sodium alginate is a soluble dietary fiber extracted from brown seaweed and its solution has been used as a hemostatic agent to treat gastrointestinal bleeding due to gastric ulcers. Whether sodium alginate has therapeutic effects on NSAID-induced SII and its mechanism of action are not known. Here, we investigated if administration of two forms (high-molecular-weight (HMW) and low-molecular-weight (LMW)) of sodium alginate could ameliorate indomethacin-induced SII. Pretreatment with HMW sodium alginate or LMW sodium alginate before indomethacin administration improved ulceration and the resultant intestinal shortening was associated with reduced histological severity of mucosal injury and ameliorated mRNA expression of inflammation-related molecules in the small intestine. We found that mRNAs of secretory Muc2 and membrane-associated Muc1, Muc3 and Muc4 were expressed in the small intestine. mRNA expression of Muc1-4 was increased in indomethacin-induced SII, and these increases were prevented by sodium alginate. Thus, administration of sodium alginate could be a therapeutic approach to prevent indomethacin-induced SII.

Abstract
The effect of rebamipide, a mucosal protective drug, on small intestinal mucosal injury caused by indomethacin was examined using a rat model. Indomethacin administration (10 mg/kg, p.o.) induced intestinal mucosal injury was accompanied by an increase in the numbers of intestinal bacteria particularly Enterobacteriaceae in the jejunum and ileum. Rebamipide (30 and 100 mg/kg, p.o., given 5 times) was shown to inhibit the indomethacin-induced small intestinal mucosal injury and decreased the number of Enterococcaceae and Enterobacteriaceae in the jejunal mucosa to normal levels. It was also shown that the detection rate of segmented filamentous bacteria was increased by rebamipide. PCR array analysis of genes related to inflammation, oxidative stress and wound healing showed that indomethacin induced upregulation and downregulation of 14 and 3 genes, respectively in the rat jejunal mucosa by more than 5-fold compared to that of normal rats. Rebamipide suppressed the upregulated gene expression of TNFα and Duox2 in a dose-dependent manner. In conclusion, our study confirmed that disturbance of intestinal microbiota plays a crucial role in indomethacin-induced small intestinal mucosal injury, and suggests that rebamipide could be used as prophylaxis against non-steroidal anti-inflammatory drugs -induced gastrointestinal mucosal injury, by modulating microbiota and suppressing mucosal inflammation in the small intestine.

Abstract
Background: Continuous administration of low-dose nonsteroidal anti-inflammatory drugs such as indomethacin (IND) is associated with an increased risk of gastrointestinal damage. In this study, the authors developed IND-loaded redox nanoparticles (IND@RNPO) with core–shell-type polymeric micelles possessing nitroxide radicals as reactive oxygen species scavengers. Results: Orally administered IND@RNPO significantly accumulated in the intestinal mucosa and improved blood uptake of IND. Because of the reactive oxygen species-scavenging effect, IND@RNPO did not cause severe inflammation in the small intestine; this effect sharply contrasted with those of orally administered free-IND and IND-loaded polymeric micelles that do not possess reactive oxygen species scavengers. Conclusion: Oral IND@RNPO administration is a useful approach for improving the oral bioavailability of IND and suppressing its adverse effects.
