Panax Notoginseng Saponins Combined with Dual Antiplatelet Drugs Potentiates Anti-Thrombotic Effect with Alleviated Gastric Injury in A Carotid Artery Thrombosis Rat Model. J Stroke Cerebrovasc Dis 2022; 31:106597. [PMID: 35716522 DOI: 10.1016/j.jstrokecerebrovasdis.2022.106597] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2022] [Revised: 06/02/2022] [Accepted: 06/08/2022] [Indexed: 10/18/2022] Open
Abstract
OBJECTIVE To observe the combination effects of Panax notoginseng saponins (PNS)and dual antiplatelet drugs (DAPT), and to explore the mechanism via cyclooxygenase /prostaglandin pathway. METHODS Right carotid artery thrombosis was induced in Wistar rats by infiltration with 70% FeCl3, and the animals were randomly divided into sham group, model group, DAPT group and PNS + DAPT group, intragastrically treated for 4 weeks. The cerebral pia mater microcirculation was observed in vivo after anesthetizing by anatomical microscope. The wet weight of carotid artery thrombosis was measured. Gastric mucosal injury was observed by hematoxylin and eosin staining. Platelet aggregation rate was detected with adenosine diphosphate -induced turbidimetry. Platelet CD62p expression was detected by flow cytometry. Concentrations of 6-Ketoprostaglandin F1 alpha, prostaglandin E2 in gastric mucosa and thromboxane B2, 6-Ketoprostaglandin F1 alpha, tissue plasminogen activator, plasminogen activator inhibitor, and fibrin fragment D in the plasma were measured by radioimmunoassay. RESULTS PNS and DAPT increased the blood flow volume of cerebral pia mater and decreased erythrocyte aggregation and leukocyte adhesion of model rats. Compared to DAPT, PNS and DAPT further reduced the weight of carotid artery thrombosis with enhanced inhibition of platelet aggregation, increased tissue plasminogen activator levels and decreased fibrin fragment D levels. PNS and DAPT alleviated gastric injury induced by dual antiplatelet drugs and upregulated the expression of 6-Ketoprostaglandin F1 alpha in the gastric mucosa compared with DAPT. CONCLUSIONS PNS combined with DAPT increased anti-thrombosis effects of DAPT and mitigated DAPT-related gastric injury. The underlying mechanisms may be associated with enhanced antiplatelet aggregation and activation of the fibrinolytic system and up-regulation of 6-Ketoprostaglandin F1 alpha expression in gastric mucosa.

Effectiveness of the polyphenols-rich Sedum dendroideum infusion on gastric ulcer healing in rats: Roles of protective endogenous factors and antioxidant and anti-inflammatory mechanisms. JOURNAL OF ETHNOPHARMACOLOGY 2021; 278:114260. [PMID: 34062247 DOI: 10.1016/j.jep.2021.114260] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/20/2021] [Revised: 05/21/2021] [Accepted: 05/25/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Peptic ulcer is an inflammatory disease that therapeutic options are mainly focused in antisecretory drugs. Sedum dendroideum Moc & Sessé ex DC (Crassulaceae) is employed in folk medicine for the treatment of gastric ulcers. Recently, our group demonstrated that Sedum dendroideum infusion (SDI) is rich in polyphenols (flavonol glycosides, myricetin, quercetin and kaempferol) and promoted gastroprotection against acute ulcer models, without changes gastric acid secretion. AIM OF THE STUDY Here, we follow the investigation of the healing effects of SDI (ED50 = 191 mg/kg) in the chronic gastric ulcer model induced by 80% acetic acid in rats, elucidating underlying mechanisms. MATERIAL AND METHODS Rats were orally treated with vehicle (water, 1 mL/kg), SDI (191 mg/kg), omeprazole (40 mg/kg) or sucralfate (100 mg/kg) twice daily for 5 days after ulcer induction. Following treatments, toxicological effects, macroscopic ulcer appearance, microscopic histological (HE, mucin PAS-staining) and immunohistochemical (PCNA and HSP70) analysis, inflammatory (MPO and NAG activity, cytokine levels measurements) and antioxidant (SOD and CAT) parameters were investigated in gastric ulcer tissues. RESULTS Oral treatment with SDI accelerated gastric ulcer healing, maintained mucin content and promoted epithelial cell proliferation. SDI also reduced neutrophil and mononuclear leukocyte infiltration, TNF-α and IL-1β levels and the oxidative stress, restoring SOD and CAT activities in the ulcer tissue. CONCLUSIONS The gastric healing effect of SDI was mediated through endogenous protective events as well as due to the anti-inflammatory and antioxidant actions. Our observations support and reinforce the traditional utilize of Sedum dendroideum as a natural nontoxic therapeutic alternative for the treatment of gastric ulcers.

J Gastroenterol Hepatol 2018; 33:156-163. [PMID: 28497645 DOI: 10.1111/jgh.13822] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2017] [Revised: 04/20/2017] [Accepted: 05/09/2017] [Indexed: 12/18/2022]
Abstract
BACKGROUND AND AIM Patients with high Rockall scores have increased risk of rebleeding and mortality within 30 days after peptic ulcer bleeding, but long-term outcomes deserve follow-up after cessation of proton pump inhibitors. The paper aimed to validate whether patients with high Rockall scores have more recurrent ulcer bleeding in a 3.5-year longitudinal cohort. METHODS Between August 2011 and July 2014, 368 patients with peptic ulcer bleeding were prospectively enrolled after endoscopic hemostasis to receive proton pump inhibitors for at least 8 to 16 weeks. These subjects were categorized into either a Rockall scores ≥6 group (n = 257) or a Rockall scores <6 group (n = 111) and followed up until July of 2015 to assess recurrent ulcer bleeding. RESULTS The proportion of patients with rebleeding during the 3.5-year follow-up was higher in patients with Rockall scores ≥6 than in those with scores <6 (10.51 vs. 3.63 per 100 person-year, P = 0.004, log-rank test). Among patients with Rockall scores ≥6, activated partial thromboplastin time prolonged ≥1.5-fold (P = 0.045), American Society of Anesthesiologists physical status class ≥III (P = 0.02), and gastric ulcer (P = 0.04) were three additional independent factors found to increase rebleeding risk. The cumulative rebleeding rate was higher in patients with Rockall scores ≥6 with more than or equal to any two additional factors than in those with fewer than two additional factors (15.69 vs. 7.63 per 100 person-year, P = 0.012, log-rank test). CONCLUSIONS Patients with Rockall scores ≥6 are at risk of long-term recurrent peptic ulcer bleeding. The risk can be independently increased by the presence of activated partial thromboplastin time prolonged ≥1.5-fold, American Society of Anesthesiologists class ≥III, and gastric ulcer in patients with Rockall scores ≥6.

Abstract
The present study was designed to investigate the gastroprotective effect of xanthones 7-preniljacareubin (PJB), 1,3,5,6-tetrahydroxy xanthone (THX), 3-demethyl-2-geranyl-4-prenylbellidypholine (DGP) and 1,5,8-trihydroxy-4', 5'-dimethyl-2H-pyrane (2,3:3,2)-4-(3-methylbut-2-enyl) xanthone (TDP) isolated of branches from G. achachairu. Their structures were identified through the spectroscopic analysis in comparison with previously reported data. The xanthones were tested at dose of 10 mg/kg against ethanol 60%/HCl 0.3 N-induced gastric ulcer in female swiss mice. The xanthones PJB, THX, DGP and TDP exhibit gastroprotective effect after intraperitoneal treatment, but only the first two displayed anti-ulcer activity after oral administration. Both PJB and THX augmented the antioxidative capacity of tissue by an increase in glutathione levels, as well as were able to prevent an increase in myeloperoxidase activity and tumor necrosis factor level. On the other hand, only THX showed an in vitro free radical scavenger activity, and only PJB avoided mucus depletion on gastric mucosa, which was not associated with an increase in mucin production at glandular level. In addition, PJB and THX inhibited the in vitro H(+)K(+)-ATPase activity at similar range as omeprazole. Together, these results demonstrate the anti-ulcer efficacy of xanthones isolated from G. achachairu, which can contribute for future directions in the development of effective strategies to improve gastric diseases.

Abstract
Ampelopsis grossedentata, an indigenous plant in southern China, has been used for treating pharyngitis in traditional Chinese medicine for hundreds of years. In this study, we explored the anti-inflammatory activity of dihydromyricetin (1), its major bioactive component, and the underlying mechanism of this action. We demonstrated that 1 suppressed the levels of pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) as well as increased the level of the anti-inflammatory cytokine interleukin-10 (IL-10) in lipopolysaccharide (LPS)-treated mice. Moreover, 1 was found to markedly inhibit the production of nitric oxide (NO) and the levels of TNF-α, IL-1β, and IL-6, whereas it increased the level of IL-10 in LPS-induced RAW 264.7 macrophage cells. Compound 1 also reduced the protein expression of inducible nitric oxide synthase (iNOS), TNF-α, and cyclooxygenase-2 (COX-2) in macrophage cells. Furthermore, 1 suppressed the phosphorylation of NF-kappa B (NF-κB) and IκBα as well as the phosphorylation of p38 and JNK but not ERK1/2 in LPS-stimulated macrophages. Taken together, the present results suggest that 1 exerts its topical anti-inflammatory action through suppressing the activation of NF-κB and the phosphorylation of p38 and JNK. Thus, 1 may be a potentially useful therapeutic agent for inflammatory-related diseases.

Abstract
Peptic ulcer bleeding is a common emergency. Management of ulcer bleeding requires prompt risk stratification, initiation of pharmacotherapy, and timely evaluation for endoscopy. Although endoscopy can achieve primary hemostasis in more than 90% of peptic ulcer bleeding, rebleeding may occur in up to 15% of patients after therapeutic endoscopy and is associated with heightened mortality. Early identification of high-risk patients for rebleeding is important. Depending on bleeding severity and center availability, patients with rebleeding may be managed by second endoscopy, transarterial angiographic embolization, or surgery. This article reviews the current management of peptic ulcers with an emphasis on rebleeding.

Abstract
Background: Alpha-pinene (α-pinene) is a monoterpene commonly found in essential oils with gastroprotective activity obtained from diverse medicinal plants, including Hyptis species. The genus Hyptis (lamiaceae) consists of almost 400 species widespread in tropical and temperate regions of America. In the north and northeastern Brazil, some Hyptis species are used in traditional medicine to treat gastrointestinal disturbances. Objective: The present study has investigated the gastoprotective effect of purified α-pinene in experimental gastric ulcer induced by ethanol and indomethacin in mice. Materials and Methods: Gastric ulcers were induced in male Swiss mice (20-30 g) by oral administration of absolute ethanol or indomethacin 45 min after oral pretreatment with vehicle, standard control drugs or α-pinene (10, 30, and 100 mg/kg). One hour after the ulcerative challenges, the stomach were removed, and gastric lesions areas measured. The effects of α-pinene on the gastric juice acidity were determined by pylorus ligation model. The gastrointestinal motility and mucus depletion were determined by measuring the gastric levels of phenol red and alcian blue, respectively. Hematoxylin and eosin stained sections of gastric mucosa of the experimental groups were used for histology analysis. Results: α-pinene pretreatment inhibited ethanol-induced gastric lesions, reduced volume and acidity of the gastric juice and increased gastric wall mucus (P < 0.05). Furthermore, we showed an interesting correlation between concentration of α-pinene and gastroprotective effect of Hyptis species (P Pearson = 0.98). Conclusion: Our data showed that the α-pinene exhibited significant antiulcerogenic activity and a great correlation between concentration of α-pinene and gastroprotective effect of Hyptis species was also observed.

Abstract
The monoterpene β-myrcene has been widely used in cosmetics, food and beverages, and it is normally found in essential oil from citrus fruit. The aim of this study was to investigate the anti-ulcer effects of β-myrcene on experimental models of ulcers that are induced by ethanol, NSAIDs (non-steroidal anti-inflammatory drugs), stress, Helicobacter pylori, ischaemia-reperfusion injury (I/R) and cysteamine in order to compare with the essential oil of Citrus aurantium and its major compound limonene. The results indicate that the oral administration of β-myrcene at a dose of 7.50mg/kg has important anti-ulcer activity with significantly decreased gastric and duodenal lesions as well as increased gastric mucus production. The results showed treatment with β-myrcene caused a significant increase in mucosal malondialdehyde level (MDA), an important index of oxidative tissue damage. The β-myrcene was also endowed with marked enhancement of antioxidant enzyme activity from GR system as evidenced by the decreased activity of superoxide dismutase (SOD) and increased levels of glutathione peroxidase (GPx), glutathione reductase (GR), and total glutathione in gastric tissue. Our results also shown that treatment with β-myrcene is not involved with thioredoxin reductase (TrxR) activity. Our results reveal, for the first time, the importance of β-myrcene as an inhibitor of gastric and duodenal ulcers and demonstrate that an increase in the levels of gastric mucosa defence factors is involved in the anti-ulcer activity of β-myrcene.

Abstract
INTRODUCTION Duodenal ulcer penetration into the liver is a rare, but serious complication. Its frequency was thought to have decreased owing to advances in therapies for peptic ulcers. However, we encountered a case in which the duodenal ulcer had penetrated into a previous hemihepatectomy site. PRESENTATION OF CASE A 69-year-old man with a history of left hemihepatectomy 20 months previously presented to the emergency room with sudden-onset abdominal pain and nausea. An upper gastrointestinal examination with a fiberscope revealed a giant ulcer in the duodenal bulb. In addition, a foreign body was detected at the ulcer floor and was strongly suspected of being a ligature from previous hemihepatectomy. DISCUSSION The presence of a gas-filled liver mass and bowel wall thickening with inflammatory changes are important imaging findings for prompt diagnosis of such a condition, but in this case, none of these were reported. Further, no definite abscess was found. Thus, the patient was treated conservatively with a proton pump inhibitor. CONCLUSION This case demonstrates the importance of using absorbable suture materials, adequate lavage in the postoperative peritoneal space and gastroduodenal mucosal protection postoperatively.
