Abstract
ETHNOPHARMACOLOGY RELEVANCE Traditional herbal medicines have been considered as a novel and effective way to treat many diseases. Lizhong decoction (LZD), a classical prescription composed of Zingiber officinale Rosc., Panax ginseng C. A. Mey., Atractylodes macrocephala Koidz., and Glycyrrhiza uralensis Fisch., has been used to treat gastrointestinal disorders in clinical practices for thousands of years. However, the mechanism of LZD in alleviating ulcerative colitis (UC) is still unclear. AIM OF THE STUDY The purpose of this study was to clarify the potential molecular mechanism of LZD in improving UC. MATERIALS AND METHODS The amelioration of LZD on dextran sodium sulfate (DSS)-induced UC mice was evaluated by body weight, colon length, pathology of colon tissues, pro-inflammatory cytokines, and intestinal tight junction (TJ) proteins. Moreover, the gene expression profiles of UC patients were extracted to investigate potential pathological mechanisms of UC. The influence of LZD on ferroptosis was analyzed by iron load, malondialdehyde (MDA), and the expression of ferroptosis-associated proteins. Meanwhile, the inhibition of LZD on oxidative stress (OS) was assessed by the superoxide dismutase (SOD) activity, as well as the expression levels of glutathione (GSH) and glutathione disulfide (GSSG). Furthermore, the influence of LZD on ferroptosis was assessed by inhibiting nuclear factor (erythroid-derived-2)-like 2 (Nrf2). RESULTS LZD showed significant therapeutic effects in UC mice, including reduction of intestinal injury and inflammation. Moreover, LZD treatment notably upregulated the expression of TJ proteins. Further investigation indicated that LZD significantly inhibited the ferroptosis of enterocytes by decreasing iron load and MDA, and increasing the expression levels of solute carrier family 7 member 11 (SLC7A11) and glutathione peroxidase 4 (GPX4) in colon tissues. Furthermore, the decreased activity of SOD, reduced level of GSH, and increased content of GSSG in UC mice were notably reversed by LZD. Consistent with in vivo results, LZD could markedly inhibit ferroptosis and OS in RSL3-induced Caco-2 cells. Mechanistically, LZD alleviated ferroptosis by suppressing OS through the activation of Nrf2 signaling. CONCLUSIONS Collectively, LZD remarkably improved intestinal pathological injury in UC mice, and its potential mechanism was the suppression of ferroptosis in enterocytes by the Nrf2/SLC7A11/GPX4 pathway.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Gastric ulcer (GU) is the injury of the gastric mucosa caused by the stimulation of various pathogenic factors penetrating the deep mucosal muscle layer. An increasing number of studies have shown that traditional Chinese medicine (TCM) is highly effective in treating GU due to its multitarget, multilevel, and multi-pathway effects. AIM OF THE STUDY To review the latest research progress in the treatment of GU by TCM, including clinical and experimental studies, focusing on the target and mechanism of action of drugs and providing a theoretical basis for the treatment of GU by natural herbs. MATERIALS AND METHODS Electronic databases (PubMed, Elsevier, Springer, Web of Science, and CNKI) were searched using the keywords "gastric ulcer", "gastric mucosal lesion", "TCM" and or paired with "peptic ulcer" and "natural drugs" for studies published in the last fifteen years until 2023. RESULTS TCM, including single components of natural products, Chinese patent medicines (CPM), and TCM decoction, is expected to treat GU by regulating various mechanisms, such as redox balance, inflammatory factors, angiogenesis, gastric mucosal protective factors, intestinal flora, apoptosis, and autophagy. CONCLUSIONS We discussed and summarized the mechanism of TCM in the treatment of GU, which provided a sufficient basis for TCM treatment of GU.

Abstract
Berberine is a natural isoquinoline alkaloid with low toxicity, which exists in a wide variety of medicinal plants. Berberine has been demonstrated to exhibit potent prevention of indomethacin-induced gastric injury (GI) but the related mechanism remains unclear. In the present study, liquid chromatography-mass spectrometry (LC-MS)-based metabolomics was applied for the first time to investigate the alteration of serum metabolites in the protection of berberine against indomethacin-induced gastric injury in rats. Subsequently, bioinformatics was utilized to analyze the potential metabolic pathway of the anti-GI effect of berberine. The pharmacodynamic data indicated that berberine could ameliorate gastric pathological damage, inhibit the level of proinflammatory factors in serum, and increase the level of antioxidant factors in serum. The LC-MS-based metabolomics analysis conducted in this study demonstrated the presence of 57 differential metabolites in the serum of rats with induced GI caused by indomethacin, which was associated with 29 metabolic pathways. Moreover, the study revealed that berberine showed a significant impact on the differential metabolites, with 45 differential metabolites being reported between the model group and the group treated with berberine. The differential metabolites were associated with 24 metabolic pathways, and berberine administration regulated 14 of the 57 differential metabolites, affecting 14 of the 29 metabolic pathways. The primary metabolic pathways affected were glutathione metabolism and arachidonic acid metabolism. Based on the results, it can be concluded that berberine has a gastroprotective effect on the GI. This study is particularly significant since it is the first to elucidate the mechanism of berberine's action on GI. The results suggest that berberine's action may be related to energy metabolism, oxidative stress, and inflammation regulation. These findings may pave the way for the development of new therapeutic interventions for the prevention and management of NSAID-induced GI disorders.

Abstract
OBJECTIVES This study aimed to investigate the effect of Periplaneta americana extract, a traditional Chinese medicine, on hard palate mucosal wound healing and explore the underlying mechanisms. DESIGN Hard palate mucosal wound model was established and the effects of Periplaneta americana extract on hard palate mucosal wound healing were investigated by stereomicroscopy observation and histological evaluation in vivo. Human oral keratinocytes and human gingival fibroblasts, which play key roles in hard palate mucosal wound healing, were selected as the main research cells in vitro. The effects of Periplaneta americana extract on cell proliferation, migration, and collagen formation were determined by cell counting kit-8 (CCK-8) assay, Transwell assay, and Van Gieson staining. The underlying mechanism was revealed by RNA sequencing, and results were verified by western blot assay. RESULTS Stereomicroscopy observation and H&E staining confirmed that Periplaneta americana extract accelerated the healing rate of hard palate mucosal wound (p < 0.001) in vivo. Transwell assay and Van Gieson staining assay showed that Periplaneta americana extract promoted the migration and collagen formation of human oral keratinocytes (p < 0.001) and human gingival fibroblasts (p < 0.001) in vitro. Mechanistically, RNA sequencing and western blot assay demonstrated that Periplaneta americana extract promoted hard palate mucosal wound healing via PI3K/AKT signaling, and the beneficial effects of Periplaneta americana extract were abrogated by the PI3K inhibitor LY294002. CONCLUSIONS Periplaneta americana extract shows promising effects for the promotion of hard palate mucosal wound healing and may be a novel candidate for clinical translation.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Huang-Qi-Jian-Zhong-Tang (HQJZT) is a canonical traditional Chinese medicine (TCM) formula that has been widely used in both the prevention and treatment of gastrointestinal diseases, including gastric ulcer, duodenal ulcer, and chronic atrophic gastritis, in China. AIM OF THE STUDY In the present study, we investigated the gastroprotective potential of HQJZT in a rat model of indomethacin (IND)-induced gastric ulcer and explained the biochemical, cellular, and molecular mechanisms involved. MATERIALS AND METHODS Observations were conducted at the macroscopic level to ascertain the ulcer index (UI) and the curative index (CI). Histopathological examinations were conducted, and a microscopic score (MS) was computed. The gastric juice volume, total acidity, pH value, and pepsin activity were quantified. Antioxidant and oxidative parameters were assessed, namely GSH, CAT, SOD, and MDA content. The RFLSI Pro instrument was employed to measure the blood flow within the gastric mucosa continuously. The mRNA levels of the inflammatory cytokines were assessed using droplet digital PCR (ddPCR). Molecular docking was employed to examine the interaction between representative active components of HQJZT and the binding sites associated with the NF-κB and STAT signaling pathways. The protein expression and localization of p-JAK, p-STAT, p-IκBβ, and p-NF-κB were evaluated through immunofluorescence analysis. RESULTS The administration of HQJZT treatment demonstrated a significant reduction in gastric lesions induced by IND, leading to a notable decrease in the UI. Additionally, HQJZT treatment significantly decreased gastric juice volume, acidity, and pepsin activity, accompanied by increased pH value. IND-treated stomachs exhibited severe hemorrhagic necrosis, submucosal edema, and epithelial cell destruction. However, the administration of HQJZT effectively counteracted these pathological changes. Furthermore, HQJZT administration significantly increased blood flow to the gastric mucosa. HQJZT enhanced antioxidant defenses and modulated oxidative stress by increasing SOD, CAT, and GSH activities while reducing MDA levels. Moreover, HQJZT reversed IND-induced increases in mRNA expression levels of inflammatory cytokines. Molecular docking analysis revealed that the representative active components of HQJZT could bind to the NF-κB and STAT signaling pathways. In addition, immunofluorescence microscopy revealed that HQJZT markedly attenuated the phosphorylation of IκΒβ, NF-κB, JAK, and STAT. CONCLUSIONS The therapeutic and protective effect of HQJZT on gastric ulcers is attributed to its ability to suppress gastric acid secretion, enhance antioxidative defenses and blood flow, mitigate proinflammatory cytokines, and inhibit the activation of NF-κB and STAT signaling pathways.

Abstract
Background: Gastric ulcers (GUs) are prevalent digestive disorders worldwide. Wuzhuyu Decoction (WZYT) is a traditional Chinese medicine that has been employed for centuries to alleviate digestive ailments like indigestion and vomiting. This study aims to explore the potential effects and underlying mechanisms of WZYT on alcohol induced gastric ulcer treatment. Methods: We employed macroscopic assessment to evaluate the gastric ulcer index (UI), while the enzyme-linked immunosorbent assay (ELISA) was utilized for detecting biochemical indicators. Pathological tissue analysis involved hematoxylin-eosin (H&E) staining and Periodic Acid-Schiff (PAS) staining to assess gastric tissue damage. Additionally, the integration of network analysis and metabolomics facilitated the prediction of potential targets. Validation was conducted using Western blotting. Results: The research revealed that WZYT treatment significantly reduced the gastric ulcer index (UI) and regulation of alcohol-induced biochemical indicators levels. Additionally, improvements were observed in pathological tissue. Network analysis results indicated that 62 compounds contained in WZYT modulate alcohol-induced gastric ulcers by regulating 183 genes. The serum metabolomics indicated significant changes in the content of 19 metabolites after WZYT treatment. Two pivotal targets, heme oxygenase 1 (HMOX1) and albumin (ALB), are believed to assume a significant role in the treatment of gastric ulcers by the construction of "compounds-target-metabolite" networks. Western blot analysis confirmed that WZYT has the capacity to elevate the expression of HMOX1 and ALB targets. Conclusion: The integration of network analysis and metabolomics provides a scientific basis to propel the clinical use of WZYT for GUs. Our study provides a theoretical basis for the use of Wuzhuyu decoction in the treatment of gastric ulcers.

Abstract
Background: Few studies have investigated traditional Chinese medicine (TCM) utilization patterns for irritable bowel syndrome (IBS), despite the potential benefits of exploring TCM utilization patterns in optimizing TCM management. This study aimed to evaluate TCM utilization patterns and clinical features for IBS patterns in Taiwan. Methods: This was a population-based cross-sectional study using claim data from the National Health Insurance Research Database between 2012 and 2018. Patients newly diagnosed with IBS and aged over 20 years were included. The TCM utilization patterns and characteristics, including Chinese herbal medicine (CHM) treatment types and prescription patterns, were evaluated. Results: A total of 73,306 patients newly diagnosed with IBS used TCM for IBS at least once. Females used TCM for IBS more than males (female-to-male ratio = 1.89: 1). The age distribution showed a peak at 30-39 years (27.29%), followed by 40-49 years (20.74%) and 20-29 years (20.71%). Patients who received Western medications for IBS had a lower tendency to seek TCM. CHM was the most commonly used TCM modality (98.22%), with Jia-wei-xiao-yao-san being the most commonly prescribed Chinese herbal formula and Bai-zhu being the most frequently prescribed single Chinese herb. Conclusion: This study enhances our understanding of TCM usage patterns for IBS, particularly CHM prescriptions. Further research is needed to investigate commonly used TCM formulas and individual herbs.

Abstract
Currently, considerable attention is focused on exploring the potential relationship between herbal medicine (HM) and the gut microbiome in terms of thermoregulation, which is an important aspect of human health, in modern system biology. However, our knowledge of the mechanisms of HM in thermoregulation is inadequate. Here, we demonstrate that the canonical herbal formula, Yijung-tang (YJT), protects against hypothermia, hyperinflammation, and intestinal microbiota dysbiosis in PTU-induced hypothyroid rats. Notably, these properties were associated with alterations in the gut microbiota and signaling crosstalk between the thermoregulatory and inflammatory mediators in the small intestine and brown adipose tissue (BAT). In contrast to the conventional drug L-thyroxine for curing hypothyroidism, YJT has an efficacy for attenuating systematic inflammatory responses, related with depression in intestinal TLR4 and Nod2/Pglyrp1 signaling pathways. Our findings suggest that YJT could promote BAT thermogenesis and prevent systemic inflammation in PTU-induced hypothyroid rats, which was associated with its prebiotic effect on modulating of the gut microbiota and gene expression with relevance in the enteroendocrine function and innate immune systems. These findings may strengthen the rationale of the microbiota-gut-BAT axis for a paradigm shift to enable holobiont-centric medicine.

Abstract
Nine undescribed geranylgeranylated derivatives (chinensens A-G), including malic acid derivative (A) and phenolic derivatives (B-E), as well as two pairs of enantiomers, [(R), (S)]-chinensens F and [(R), (S)]-chinensens G, were isolated from the roots of Rhus chinensis Mill. Their structures were elucidated by UV, IR, HRESIMS, 1D and 2D NMR spectra, as well as optical rotations. The 95% EtOH extract (95% EXT, 500 mg/kg, p. o.) of the roots of Rhus chinensis and the 95% EtOH fraction (95% FRA, 500 mg/kg, p. o.) from the microporous resin column significantly alleviated indomethacin-induced or water immersion-restraint stress-induced damage in rat gastric mucosa with inhibitory rates from 53% to 89%. The racemic mixture (chinensen G) and its enantiomers [(R), (S)]-chinensens G showed weak activities against H+,K+-ATPase (20%-24%) at a concentration of 0.1 mM, respectively.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The prescription of Wei-Tong-Xin (WTX) is improved based on the prescription "Wanyingyuan", a famous decoction documented in the book of Huatuozhongzangjing in the Han dynasty. Many years of clinical verification have demonstrated that WTX can be used to treat gastrointestinal diseases, especially gastric ulcer (GU). However, the potential pharmacological mechanism is undefined. AIM OF THE STUDY This research was conducted to explore the pharmacological mechanisms under the consideration of the therapeutical effect of WTX against GU by combining the network pharmacology strategy and in-vivo verified experiments. MATERIALS AND METHODS A prediction network describing the relationship between WTX and GU was established based on information collected from multiple databases. Then, the intersecting protein-protein interaction (PPI) network of the drug-disease overlapping gene targets was constructed, and several key targets related to both WTX and GU were obtained. Besides, the Gene Ontology (GO) biological enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were performed to investigate the key target genes and pathways of WTX against GU. Then, the candidate targets and signaling pathways of network pharmacology were validated in a rat model of GU induced by indomethacin following the results and available proof. RESULTS There are 243 targets obtained from the 65 active ingredients in WTX, and 1362 disease targets related to GU were identified. Then, 6 key targets were determined with the PPI interaction network, which was structured from 126 overlapping gene targets. GO and KEGG analyses revealed that the phosphoinositide-3-kinase/protein kinase B (PI3K/AKT) signaling pathway might play a crucial role in the therapeutic mechanism of GU. In vivo verified experiments, WTX significantly reduced the ulcer area and improved the histopathological appearance of gastric tissues. Moreover, down-regulated the protein levels of IL6, TNF-α, and Caspase 3 in the gastric tissues while up-regulating the expression of p-PI3K, p-AKT, p-P53, and VEGFA compared to the model group. CONCLUSION WTX, an ancient traditional Chinese medicine (TCM) compound prescription, may affect the inflammatory response and apoptosis process by regulating PI3K/AKT signaling pathway and related gene targets. Therefore, it is an effective drug candidate for the modern treatment of GU.

Abstract
Objective The present study aimed at the anti-inflammatory and antioxidant effects of the extract of Bruguiera gymnorrhiza (L.) Lam. fruit (BGF) on the gastric injury. Materials and Methods The chemical components in the extract of BGF were used in UPLC/Q-Orbitrap analysis. 60 SD rats were randomized into six groups: normal group (MC), ethanol-injured control group (EC), omeprazole group, and three groups with different doses (50, 100, and 200 mg/kg) of BGF. After continuous administration for seven days, the stomachs of rats were taken out to observe the pathological gastric tissue changes; inflammatory factors and oxidative stress markers in the stomach tissues were measured. Western blot (WB) analyses were conducted to explore the mechanism of BGF on gastric tissue and RAW 246.7 cells with excessive inflammation. Results BGF enhanced gastric mucosal protection by improving the mucosal blood flow of the stomach and significantly decreased inflammatory factors and oxidative stress markers. Moreover, BGF significantly reduced the expression of p-NF-κB p65. Consistently, BGF demonstrated similar effects on LPS-induced RAW 264.7 cells as it did in vivo. Conclusion BGF could accelerate the healing of gastric injury by exerting antioxidant and anti-inflammatory effects and maintaining mucosal integrity.

Abstract
This study aimed at investigating gastroprotective activity of Hericium erinaceus polysaccharide (HEP) and characterizing one of its bioactive fractions. Acetic acid-induced gastric ulcer (GU) rat model was used to evaluate the gastroprotective activity of HEP, while H2O2-induced injury GES-1 cell model was conducted to screen the bioactive fractions from HEP. Moreover, one of the bioactive fractions was characterized using methylation and 1D/2D NMR analysis. Results indicated HEP treatment could ameliorate acetic acid-induced GU in rats. HEP supplement decreased levels of interleukin-6, tumor necrosis factor-α and malondialdehyde and myeloperoxidase activity, and increased releases of nitric oxide, prostaglandin E2, epidermal growth factor, vascular endothelial growth factor and basic fibroblast growth factor and superoxide dismutase activity in gastric tissues of ulcerated rats. Five purified polysaccharides from HEP were screened to be bioactive fractions with cytoprotection on H2O2-induced injury in GES-1 cells. Among them, RP-S was characterized to be a (1 → 6)-β-D-glucan, whose backbone was composed of →6)-β-D-Glcp-(1 → residue and branched with T-β-D-Glcp-(1 → residue at O-3 position. In conclusion, HEP possessed gastroprotection against acetic acid-induced GU in rats and one of its bioactive fractions was a β-D-glucan. This study supports the utilization of HEP in anti-GU and provides evidences for the structure of gastroprotective HEP.

Abstract
Background Shaoyao-Gancao decoction (SGD) is a classic prescription in traditional Chinese medicine. SGD is effective in the treatment of gastric and duodenal ulcers. However, the biological activity and possible mechanisms of SGD in the treatment of gastric ulcers have not been fully elucidated. The purpose of this study was to scientifically evaluate the protective effect and potential mechanism of SGD against ethanol-induced gastric ulcers in rats. Methods A single gavage of 10 mL/kg of 75% ethanol was used to establish a rat gastric ulcer model. A histopathological examination of the gastric tissue was performed. The levels of TNF-α, EGF, PGE2, SOD, and TBARS in gastric tissue were measured by ELISA. Cellular apoptosis in gastric tissues was assessed by TUNEL assay. The expression levels of caspase-3 and Bcl-2 were determined by immunohistochemistry. The potential mechanism of SGD in treating gastric ulcers was further studied using a network pharmacology research method. Results The gastric tissue of rats with ethanol-induced gastric ulcers had obvious injury throughout the mucosal layer, which was significantly weakened in rats treated with SGD. Furthermore, treatment with SGD significantly increased the levels of EGF, PGE2, SOD, and Bcl-2 and decreased the levels of TNF-α, TBARS, and caspase-3 in the gastric tissue of rats with ethanol-induced gastric ulcers. SGD reduced ethanol-induced cell apoptosis in gastric tissue from rats with gastric ulcers. A traditional Chinese medicine-based network pharmacology study revealed that SGD exerts its anti-gastric ulcer effect by acting on multiple pathways. Conclusions The above results indicate that SGD can improve gastric ulcers induced by ethanol. Moreover, this study demonstrated multicomponent, multitarget, and multipathway characteristics of SGD in the treatment of gastric ulcers and provided a foundation for further drug development research.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE According to traditional Chinese medicine and a previous literature, many parts of Chinese sumac (Rhus chinensis Mill.), including fruits, are used as traditional herb to prevent or cure many diseases, such as inflammation, diarrhea, malaria, and other acute or chronic gastrointestinal diseases. However, the effects of the fruits on the prevention of gastric ulcer and the underlying mechanisms have not been reported. AIM OF THE STUDY This experiment aimed to investigate the preventive effect of ethanol extract (RM) from Chinese sumac fruits on indomethacin-induced gastric ulcer in mice and the underlying mechanisms. MATERIALS AND METHODS A single gavage of indomethacin was used to induce a gastric ulcer model in Kunming male mice. According to the results of histopathological analysis, immunohistochemistry and immunofluorescence analysis, as well as the expression of prostaglandin E-2, antioxidant enzymes and cytokines, the protective effect of RM on indomethacin-induced gastric ulcer was evaluated. The expression levels of several key proteins involved in oxidative stress, inflammation and apoptosis in gastric tissue were detected to illuminate the underlying mechanisms. RESULTS RM significantly reduced the ulcer index and pepsin activity, improved the microstructure of gastric mucosa and the prostaglandin E-2 content, restored the levels of glutathione and superoxide dismutase, and decreased the contents of malondialdehyde, advanced oxidation protein products, TNF-α, IL-1 β and IL-6. Further experimental results showed that RM could improve the expression levels of HO-1 and NQO1 by activating the Nrf2 protein pathway to alleviate oxidative stress in gastric tissue. At the same time, RM significantly down-regulated the expressions of p-NF-κB, p-IκBα and iNOS to relieve inflammatory response, and inhibited the cellular apoptosis of gastric tissue by up-regulating Bcl-2 and down-regulating Bax and cleaved Caspase-3. CONCLUSIONS The current work clarified that the ethanol extract from Chinese sumac fruits can improve the oxidative stress level, inflammatory response and cell apoptosis in gastric tissue by interfering with the expressions of several key regulatory proteins to prevent indomethacin-induced gastric ulcer in mice. This study may provide some insights and scientific evidence on the application of Chinese sumac fruits as a traditional herb to prevent or alleviate gastric ulcer.

Abstract
Gastric mucosal injury is caused by an imbalance between the mucosal defense and gastro-irritants, leading to gastroenteritis. Diosgenin is a steroidal sapogenin found in the wild Yam plant that has been reported with several pharmacological properties. The aim of this study is to explore the gastroprotective role of diosgenin on gastric mucosal damage caused by HCl/ethanol in rats. Male Sprague-Dawley rats were intragastrically administered with diosgenin (20 mg/kg) before HCl/ethanol (0.15 M HCl in 98 % ethanol) administration. Omeprazole was used as a positive control. Diosgenin-attenuated oxidative stress by enhancing (p < 0.05) antioxidant enzymes, reducing lipid peroxidation (MDA), and modulating nitric oxide (NO) levels. Anti-inflammatory effects of diosgenin were observed by a reduction in pro-inflammatory cytokines (p < 0.05), decreased myeloperoxidase (MPO) activities (p < 0.05), and histopathological observation of gastric mucosal damage. Western blot analysis provided evidence on the downregulation of NF-κβ by diosgenin. The findings showed that diosgenin has a significant protective role on gastric injury caused by HCl/ethanol, through its antioxidant, anti-inflammatory role, and suppression of NF-κβ and MPO activities.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Fructus Lycii and Salvia miltiorrhiza Bunge (FS) are popular Chinese herbs for the treatment of retinitis pigmentosa (RP). AIM OF THE STUDY This study was to evaluate protective effects of FS extract on RP and to explore whether FS extract exerts its protective effects via oxidative stress by regulating Nrf2/HO-1 signaling pathway. MATERIAL AND METHODS FS extract were identified by UPLC chromatographic analysis. Rd10 mice as the model of RP, followed by a 4-week FS extract treatment by intragastric administration. After the animal sacrifice, histopathological examination and Scotopic electroretinography (ERG) analysis were assessed. The oxidative stress markers were determined and the expression levels of Nrf2 and HO-1 mRNA were evaluated by qRT-PCR. The expression and distribution of Nrf2 and HO-1 protein were determined by Western blot and immunohistochemistry. RESULTS The morphological changes of Outer nuclear layer (ONL) thickness and number of the ONL were observed with a significant increased, and the functional changes of a-amplitude and b-wave amplitude were measured with a markedly increased. Treatment with FS extract remarkably increased levels of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), and decreased level of malondialdehyde (MDA). Moreover, FS extract up-regulated mRNA and protein expression of Nrf2 and HO-1. CONCLUSIONS This study indicated that FS extract can improve retinal morphology and function, which may have occurred through the regulation of the Nrf2/HO-1 pathway to inhibit the oxidative reaction.

Abstract
Aprepitant is a selective SP/NK-1 receptor antagonist and used in postoperative and chemotherapeutics induced emesis and vomiting. The aim of our study is to show aprepitant may have beneficial effects on gastrointestinal complaints in cancer patients undergoing chemotherapeutics by indomethacin-induced gastric ulcer model. A total of 48 rats were fasted 24 h for ulcer experiment. Aprepitant doses of 5, 10, 20, and 40 mg/kg were evaluated for their antiulcer activity. Omeprazole (20 mg/kg) was used as a positive control group. Six hours after 25 mg/kg indomethacin administration, all stomachs were dissected out. After macroscopic analyses, tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β), COX-1, and COX-2 mRNA levels and SOD activity, and GSH and MDA levels of stomachs were determined. Histopathological examinations were evaluated. Aprepitant administration exerted 48.14%, 49.62%, 65.92%, and 76.77% ulcer inhibition effects at 5, 10, 20, and 40 mg/kg, respectively. Aprepitant administration decreased oxidative stress and inflammatory parameters in stomach tissues dose dependently. Aprepitant administration increased stomach COX-2 mRNA levels at 20 and 40 mg/kg doses. Although aprepitant appears to be disadvantageous in terms of treating gastric ulcer due to COX enzyme inhibition according to the previous studies, aprepitant has been shown to have ulcer healing effect in our study. When aprepitant is given as an anti-nausea and vomiting drug to cancer patients undergoing chemotherapy, we can argue that it will not be necessary to add a new gastric protective agent as it also shows beneficial effects in gastrointestinal complaints.
