Abstract
Hawthorn belongs to the rose family and is a type of functional food. It contains various chemicals, including flavonoids, terpenoids, and organic acid compounds. This study aimed to review the vascular protective effects and molecular mechanisms of hawthorn and its extracts on cardiovascular diseases (CVDs). Hawthorn has a wide range of biological functions. Evidence suggests that the active components of HE reduce oxidative stress and inflammation, regulate lipid levels to prevent lipid accumulation, and inhibit free cholesterol accumulation in macrophages and foam cell formation. Additionally, hawthorn extract (HE) can protect vascular endothelial function, regulate endothelial dysfunction, and promote vascular endothelial relaxation. It has also been reported that the effective components of hawthorn can prevent age-related endothelial dysfunction, increase cellular calcium levels, cause antiplatelet aggregation, and promote antithrombosis. In clinical trials, HE has been proved to reduce the adverse effects of CVDs on blood lipids, blood pressure, left ventricular ejection fraction, heart rate, and exercise tolerance. Previous studies have pointed to the benefits of hawthorn and its extracts in treating atherosclerosis and other vascular diseases. Therefore, as both medicine and food, hawthorn can be used as a new drug source for treating cardiovascular diseases.

JOURNAL OF ETHNOPHARMACOLOGY 2023; 304:116075. [PMID: 36572328 DOI: 10.1016/j.jep.2022.116075] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/25/2022] [Revised: 12/16/2022] [Accepted: 12/17/2022] [Indexed: 06/17/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ulcerative colitis (UC) has become a healthy burden worldwide due to its insidious onset and repetitive relapse, with a rather complex etiology, including inappropriate immune response, dysbiosis, genetic susceptibility, and unhealthy diets. The Wu-Shi-Cha (WSC) formula is a widely utilized drug to protect against gastrointestinal disorders. AIM OF THE STUDY The study aspired to dissect the pertinent mechanisms of the WSC to treat UC. MATERIALS AND METHODS Network pharmacology and weighted gene co-expression network analysis (WGCNA) were performed to predict the targets of WSC in the context of UC and colorectal cancer. Dextran sodium sulfate (DSS) was used to construct murine models of experimental colitis, and the WSC was given to colitis mice for 14 days. Feces and colon samples were subjected to 16S rRNA gene sequencing combined with liquid chromatography-mass spectrometry (LC-MS) and biochemical experiments, respectively. RESULTS Network pharmacology analysis predicted that the WSC formula could orchestrate inflammation, infection, and tumorigenesis, and WGCNA based on The Cancer Genome Atlas (TCGA) database showed a potent anti-neoplastic effect of the WSC therapy for colorectal cancer. The WSC therapy rescued bursts of pro-inflammatory cytokines and colonic epithelial collapse in DSS-induced colitis mice. Moreover, the high dose of WSC treatment facilitated the alternative activation of peritoneal macrophages (Mφs) and these Mφs were conducive to the survival of intestinal stem cells (ISCs), and the disturbed homeostasis of gut microbiota was re-established after WSC treatment, as evidenced by the decreased colonization of pathological taxa in the fecal samples. CONCLUSION The WSC formula suppresses inflammation and re-establishes the homeostasis of gut microbiota, thereby ameliorating colitis progression.

Chemoprevention with a tea from hawthorn ( Crataegus oxyacantha) leaves and flowers attenuates colitis in rats by reducing inflammation and oxidative stress. FOOD CHEMISTRY-X 2021; 12:100139. [PMID: 34712949 PMCID: PMC8531563 DOI: 10.1016/j.fochx.2021.100139] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 10/01/2021] [Accepted: 10/04/2021] [Indexed: 12/19/2022]
Abstract
A tea from the leaves and flowers of hawthorn is rich in flavonoids, especially vitexin-2-O-rhamnoside. Mesalamine and hawthorn tea have positive healing effects in rats with colitis. Hawthorn tea reduces the length and area of the brownish necrotic lesions. Hawthorn tea diminishes the levels of the inflammatory markers MPO and IL-1β. Hawthorn tea regulates the activity of the oxidative stress enzymes CAT and GR.
The purpose of the study was to determine the effects of a tea from the leaves and flowers of Crataegus oxyacantha in rats with colitis. Colitis was induced by administration of 2,4,6-trinitrobenzene sulfonic acid. Hawthorn tea (HT) (100 mg/kg) was given via gavage for 21 days and the mesalamine drug (100 mg/kg) was administrated during the period of disease onset. HT was rich in total phenolic compounds (16.5%), flavonoids (1.8%), and proanthocyanidins (1.5%); vitexin-2-O-rhamnoside was the main compound detected. Mesalamine and the HT diminished the length of the lesions formed in the colon, in addition to reducing the levels of myeloperoxidase and interleukin-1β. Mesalamine was able to significantly reverse the body weight loss, while HT improved the activity of glutathione reductase and catalase. Histological scoring was not changed by the interventions, but it was highly correlated with the necrotic area. HT given at 100 mg/kg can be effective against colitis.

Abstract
Ulcerative colitis (UC) is an inflammatory bowel disease with limited therapeutic management approaches. The present study evaluated the potential therapeutic impact of betulin on acetic acid (AA)-induced UC in rats. UC was induced by intracolonic instillation of AA (3% v/v). Rats were treated with betulin (8 mg/kg, I.P., once daily) four days post AA instillation and for 14 consecutive days. Betulin attenuated AA-induced UC as evidenced by retracted macroscopic scores, serum CRP titre and LDH activity, attenuated histopathological hallmarks of UC including mucosal necrosis, haemorrhage, congestion and inflammatory cells infiltration. Moreover, betulin dampened UC-associated colonic inflammatory load with modulation of TLR4/NF-kB axis and reduction in colonic inflammatory cytokines; TNF-α, IL1β and IL-6. Nevertheless, betulin suppressed colonic apoptosis with reduced colonic caspase-3 and caspase-8 expression. The current findings confirm a beneficial therapeutic impact of betulin against UC. The prospective underlying mechanisms include down-regulation of TLR4/NF-κB and the subsequent downstream signalling pathways.

Abstract
The intestinal tract plays an essential role in protecting tissues from the invasion of external harmful substances due to impaired barrier function. Furthermore, it participates in immunomodulation by intestinal microorganisms, which is important in health. When the intestinal tract is destroyed, it can lose its protective function, resulting in multiple systemic complications. In severe cases, it may lead to systemic inflammatory response syndrome (SIRS) and multiple organ dysfunction syndrome (MODS). Thus far, there are no curative therapies for intestinal mucosal barrier injury, other than a few drugs that can relieve symptoms. Thus, the development of novel curative agents for gastrointestinal diseases remains a challenge. Ursolic acid (UA) and its isomer, Oleanolic acid (OA), are pentacyclic triterpene acid compounds. Both their aglycone and glycoside forms have anti-oxidative, anti-inflammatory, anti-ulcer, antibacterial, antiviral, antihypertensive, anti-obesity, anticancer, antidiabetic, cardio protective, hepatoprotective, and anti-neurodegenerative properties in living organisms. In recent years, several studies have shown that UA and OA can reduce the risk of intestinal pathological injury, alleviate intestinal dysfunction, and restore intestinal barrier function. The present study evaluated the beneficial effects of UA and OA on intestinal damage and diseases, including inflammatory bowel disease (IBD) and colorectal cancer (CRC).

Abstract
Background Chinese hawthorn (Crataegus pinnatifida) fruit is a traditional Chinese medicine for treatment of digestive system and cardiovascular diseases. The fruit contains polyphenol compounds, such as epicatechin, that have anti-inflammatory activity. This study aimed to investigate the effects of an alcohol extract of hawthorn fruit (HAE) on inflammation and oxidative stress in rats with doxorubicin-induced chronic heart failure (CHF). Material/Methods Rats were intraperitoneally injected with doxorubicin to induce CHF and subsequently treated with HAE intragastrically once daily for 6 weeks. At the end of the experiment, echocardiographic and hemodynamic parameters were assessed, and enzyme-linked immunoassays were used to detect the levels of cardiac injury markers (brain natriuretic peptide, creatine kinase-MB, aspartate aminotransferase, lactate dehydrogenase, copeptin, and adrenomedullin), oxidative stress markers (glutathione peroxidase and malondialdehyde), and inflammatory cytokines (interleukin [IL]-6, IL-8, IL-1β, and tumor necrosis factor-α). The IL-1β, IL-6, glutathione peroxidase-1, and catalase mRNA levels were also measured by quantitative real-time polymerase chain reaction. Results Our findings indicated that HAE exerts a cardioprotective effect, as shown by improved echocardiographic and hemodynamic parameters, decreased activity of serum myocardial enzymes, reduced serum levels of CHF markers, and inhibited inflammatory response in cardiac tissue. In addition, HAE treatment downregulated the mRNA expression of IL-1β and tumor necrosis factor-α and upregulated the mRNA expression of glutathione peroxidase-1 and catalase compared with untreated doxorubicin-induced CHF rats. Conclusions HAE shows promise for the prevention and treatment of CHF. The cardioprotective effect of HAE appears to be related to inhibition of both the inflammatory response and oxidative stress in vivo.

Abstract
Ulcerative colitis (UC) is a chronic inflammatory disease characterized by diffused inflammation of the colon and rectum mucosa. The pathogenesis of UC is multifactorial, and the exact underlying mechanisms remain poorly understood. This study aims to investigate the effect of mesalazine and atorvastatin combination in enhancing anti-inflammatory effects and attenuates progression of oxazolone colitis in rats. In the present study, male albino rats (N = 60) were divided into six groups (10 rats each), the first two groups served as normal control and a control saline group. Colitis was induced by intra-rectal administration of oxazolone in the 5th and 7th days after pre-sensitization. Then, rats were divided into untreated group, groups treated with mesalazine or atorvastatin or their combination. Colitis was assessed by colon length, body weight, and incidence of diarrhea, rectal bleeding, and histopathology of colon tissue. Colon tissues were used for measuring interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-α), IL-13, signal transducer and activator of transcription-3 (STAT-3), myeloperoxidase activity (MPO), reduced glutathione(GSH), and tissue expression of IL-10, tight junction protein zonula occludens (ZO-1), and caspase-3 genes. The combination therapy significantly attenuated progression of UC by decreasing incidence of diarrhea, rectal bleeding, weight loss, IL-13, IL-6, TNF-α, STAT-3, caspase-3, and MPO activity and significantly increased IL-10, ZO-1, colon length, and GSH content, and these effects were more superior to single drugs. These findings showed that combination therapy was able to ameliorate progression of UC and enhance anti-inflammatory effects possibly by restoring IL-10 and ZO-1 levels and limiting IL-6/STAT-3 trans-signaling.

Abstract
Purpose To examine the therapeutic effect of external adenosine on an acetic acid-induced acute ulcerative colitis model in rats. Methods Thirty male mature rats were divided into three groups as control, acute colitis (AC) and AC+adenosine group (AC+AD). AC was induced by rectal administration of 4% acetic acid (AA). 5mg/kg/day adenosine was performed i.p for 4 weeks to AC+AD group. Rectum and colon were excised for microscopic and histopathological histopathologic evaluations, and immunohistochemical analysis of nuclear factor kappa B (NF-kB). Blood samples were collected for biochemical detection of TNF-α, Pentraxin-3 and malondialdehyde (MDA) levels. Results AC group had generalized hyperemia and hemorrhage with increased macroscopic and histopathological scores compared with control (P <0.0001) while adenosine treatment decreased these scores significantly (P <0.001), with reduced distribution of disrupted epithelium, leukocyte infiltrates, and focal hemorrhage. AC group showed significantly increased immunoexpression of NF-kB in rectum, plasma and tissue levels of TNF-α, plasma Pentraxin-3 and MDA levels (P <0.0001) while adenosine reduced these levels (P < 0.05). Conclusion Adenosine appears to promote healing of colon and rectum exposed to AA-induced AC, suggesting a boosting effect of adenosine on the intestinal immune system to cure ulcerative colitis.

Abstract
The prevalence of diabetes mellitus is increasing all over the world and it is apparent that treatment of diabetic complications has the same importance as primary diabetes treatment and glycemic control. Diabetic complications occur as a result of prolonged hyperglycemia and its consequences, such as advanced glycation end products and reactive oxygen species. Impairment of lipid profile is also contributed to worsening diabetic complications. Therefore, it seems that the application of lipid-lowering agents may have positive effects on reversing diabetic complications besides glycemic control. Statins, a group of lipid-lowering compounds, have been shown to exert antioxidant, immunomodulatory, anti-inflammatory, and antiproliferative properties beyond their lipid-lowering effects. Furthermore, they have been reported to improve diabetic complications with different pathways. In this review, we will discuss the clinical importance, molecular biology of the most important microvascular/macrovascular diabetic complications, possible application of statins and their mechanism of action in retarding these complications.

Abstract
Inflammatory bowel disease (IBD) is a chronic idiopathic inflammatory disorder. A wealth of data pointed out that various aspects of chronic inflammation may be affected by several specific dietary factors. This paper calls attention to anthocyanins enriched plant food and anthocyanin dietary supplements, whose role in the management of IBD and its associated oncogenesis deems crucial. Area covered: We updated the most relevant dietary anthocyanins with potential anti-colitis and preventive effect on inflammatory associated colorectal cancer based on the recent animal and human researches along with revealing the major cellular and molecular mechanisms of action. Mounting evidence reported that anthocyanins enriched plant foods perform their protective role on IBD and inflammatory-induced colorectal cancer via different cellular transduction signaling pathways, including inflammatory transcription factors, SAPK/JNK and p38 MAPK cascade, JAK/STAT signaling, NF-kB/pERK/MAPK, Wnt signaling pathway, Nrf2 cytoprotective pathway as well as AMPK pathway and autophagy. Expert commentary: Combination of anthocyanins enriched dietary supplements with existing medications can provide new therapeutic options for IBD patients. Further, well-designed randomized control trials (RCTs) are essential to evaluate the role of anthocyanins enriched medicinal foods as well as isolated anthocyanin components as promising preventive and therapeutic dietary agents for IBD and its associated oncogenesis.

Ursolic acid (UA) has been reported to have a protective effect in colitis. However, the underlying mechanisms remain to be elucidated. In the present study, experimental ulcerative colitis was induced in male BALB/c mice by the administration of 5% dextran sulfate sodium (DSS) for 7 days, followed by treatment with UA for another 7 days. Hematoxylin & eosin staining was performed to evaluate colon tissue damage, and enzyme assays were used to measure malondialdehyde (MDA) content and superoxide dismutase (SOD) activity in colon homogenate. In addition, serum levels of interleukin (IL)‑1β and tumor necrosis factor (TNF)‑α were measured using an ELISA, and the level of nuclear factor (NF)‑κB p65 in the colonic tissues was assessed by western blotting. The 7‑day DSS administration induced marked colon damage, increased the serum levels of IL‑1β and TNF‑α, increased MDA content and decreased SOD activity in the colon homogenate. These changes were significantly improved by treatment with UA. UA also reduced the DSS‑stimulated high nuclear level of NF‑κB p65 in the colon tissues. These results demonstrate a protective role of UA in ulcerative colitis, and suggest that anti-inflammatory and antioxidant activities are involved in the underlying mechanisms.

Abstract
Crohn's disease and ulcerative colitis presently have no cure and are treated with anti-inflammatory drugs or monoclonal antibodies targeting pro-inflammatory cytokines. A variety of rodent models have been used to model chronic and acute colitis. Dietary polyphenols in foods and botanicals are of considerable interest for prevention and treatment of colitis. Many dietary polyphenols have been utilized for prevention of colitis in rodent models. Berries, green tea polyphenols, curcumin, and stilbenes have been the most extensively tested polyphenols in rodent models of colitis. The majority of polyphenols tested have inhibited colitis in rodents, but increasing doses of EGCG and green tea, isoflavones, flaxseed, and α-mangostin have exacerbated colitis. Few studies have examined combination of polyphenols or other bioactives for inhibition of colitis. Translating polyphenol doses used in rodent models of colitis to human equivalent doses reveals that supplemental doses are most likely required to inhibit colitis from a single polyphenol treatment. The ability to translate polyphenol treatments in rodent models is likely to be limited by species differences in xenobiotic metabolism and microbiota. Given these limitations, data from polyphenols in rodent models suggests merit for pursuing additional clinical studies for prevention of colitis.

Abstract
Statins are among the most widely prescribed medications in the world. In addition to lowering cholesterol, statins have been shown to have immunomodulatory effects in multiple studies. For example, statins modulate the interaction between T cells and antigen-presenting cells, resulting in decreased T-cell activation and reduced levels of inflammatory cytokines. Statins have also been demonstrated to inhibit the migration of leukocytes across vascular endothelium into tissues. Although most research on the immune effects of statins has been conducted in the context of cardiovascular, rheumatological, or metabolic disease, various studies have shown that statins may have a significant impact on intestinal immunity and mucosal inflammation. Clinical research has suggested that statins may have benefit in inflammatory bowel disease. In this article, we review the effect of statins on the immune system and gastrointestinal tract, highlighting the potential for novel therapeutic applications in inflammatory bowel disease.

Abstract
The purpose of this animal study was to evaluate the effects of hawthorn (Crataeus orientalis M Bieber.) extract on serum oxidative status and alveolar bone loss in experimental periodontitis. Twenty-seven Wistar rats were assigned to one of the following groups: non- ligated+placebo (saline) (NL, n = 9), ligature only+placebo (saline) (LO, n = 9), and ligature and treated with hawthorn extract in saline (H, n = 9) (100 mg/kg orogastrically, once a day for 11 days). Periodontitis was induced by submerging a 4/0 silk ligature in the sulcus of the mandibular right first molars of rats, and the animals were sacrificed after 11 days. Micro-CT examinations were performed for linear and volumetric parameter assessment of alveolar bone. Periodontal tissues were histopathologically examined to assess the differences among the study groups. Levels of serum total antioxidant status (TAS)/total oxidant status (TOS), and oxidative stress index (OSI) were also analyzed. Alveolar bone loss was significantly reduced by hawthorn administration compared to LO group (p<0.05). The number of inflammatory cells and osteoclasts in the LO group was significantly higher than that of the NL and H groups (p< 0.05). The number of osteoblasts in the LO and H groups was significantly higher than that of the NL group (p<0.05). TOS and OSI levels were significantly reduced in H group compared to LO group (P <0.05) and TAS levels were similar in H and NL group (p< 0.05). Hawthorn extract showed inhibitory effect on periodontal inflammation and alveolar bone loss by regulating TAS, TOS and OSI levels in periodontal disease in rats when administered systemically.

Abstract
BACKGROUND AND PURPOSE The gallnut of Rhus chinensis MILL and its main constituent penta-O-galloyl-β-D-glucose (PGG) inhibited NF-κB activation in LPS-stimulated peritoneal and colonic macrophages. Here we have investigated PGG mechanisms underlying anti-inflammatory effects of PGG in vitro and in vivo. EXPERIMENTAL APPROACH Male C57BL/6 mice (18-22 g, 6 weeks old) were used to prepare peritoneal and colonic macrophages and for the induction of colitis by intrarectal administration of 2,3,4-trinitrobenzene sulphonic acid (TNBS). A range of inflammatory markers and transcription factors were evaluated by elisa, immunoblotting, flow cytometry and confocal microscopy. KEY RESULTS Expression of Toll-like receptor (TLR)-4 or Lipopolysaccharide (LPS) binding to TLR-4 in LPS-stimulated peritoneal macrophages was not affected by PGG. However PGG inhibited binding of an anti-MyD88 antibody to peritoneal macrophages, but did not reduce binding of anti-IL-1 receptor-associated kinase (IRAK1) and IRAK4 antibodies to the macrophages with or without transfection with MyD88 siRNA. PGG potently reduced the activation of IRAK1, NF-κB, and MAPKs in LPS- or pepetidoglycan-stimulated peritoneal and colonic macrophages. PGG suppressed IL-1β, TNF-α and IL-6 in LPS-stimulated peritoneal macrophages, while increasing expression of the anti-inflammatorycytokine IL-10. Oral administration of PGG inhibited colon shortening and myeloperoxidase activity in mice with TNBS-induced colitis, along with reducing NF-κB activation and IL-1β, TNF-α, and IL-6 levels, whereas it increased IL-10. CONCLUSIONS AND IMPLICATIONS PGG reduced activation of NF-κB and MAPK signalling pathways by directly interacting with the MyD88 adaptor protein. PGG may ameliorate inflammatory diseases such as colitis.

Abstract
AIMS Ursolic acid (UA), a natural pentacyclic triterpenoid acid, has been reported to show immunomodulatory activity. This study investigated the effects of UA on nuclear factor-kappa B (NF-κB) signaling in cells and experimental murine colitis. MAIN METHODS Human intestinal epithelial cells (IECs) COLO 205 and peritoneal macrophages from IL-10-deficient (IL-10(-/-)) mice were pretreated with UA and then stimulated with tumor necrosis factor-α (TNF-α) and lipopolysaccharide (LPS), respectively. The expression of pro-inflammatory cytokines was determined by real-time RT-PCR and ELISA. The effect of UA on NF-κB signaling was examined by immunoblot analysis to detect IκBα phosphorylation/degradation and electrophoretic mobility shift assay to assess the DNA binding activity of NF-κB. For in vivo studies, dextran sulfate sodium (DSS)-induced acute colitis in C57BL/6 wild-type mice and chronic colitis in IL-10(-/-) mice were treated with or without UA. Colitis was quantified by histopathologic evaluation. Immunohistochemical staining for phosphorylated IκBα was performed in the colonic tissue. KEY FINDINGS UA significantly inhibited the production of pro-inflammatory cytokines, IκBα phosphorylation/degradation and NF-κB DNA binding activity in both IEC and IL-10(-/-) peritoneal macrophages stimulated with TNF-α and LPS, respectively. UA significantly reduced the severity of DSS-induced murine colitis, as assessed by the disease activity index, colon length, and histopathology. UA also significantly ameliorated the severity of colitis in IL-10(-/-) mice. Furthermore, UA suppressed IκBα phosphorylation in the colonic tissue. SIGNIFICANCE UA inhibits NF-κB activation in both IECs and macrophages, and attenuates experimental murine colitis. These results suggest that UA is a potential therapeutic agent for inflammatory bowel disease.
