[PMID: 38263790 DOI: 10.1111/nmo.14745] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Revised: 08/03/2023] [Accepted: 08/29/2023] [Indexed: 01/25/2024]
Abstract
BACKGROUND Inflammatory bowel diseases (IBD) are chronic diseases that are not fully understood. Drugs in use can only be applied for a short time due to their side effects. Therefore, research is needed to develop new treatment approaches. In addition, it has been proven that IBD causes degeneration in the enteric nervous system (ENS). In recent years, it has been discussed that probiotics may have positive effects in the prevention and treatment of inflammatory enteric degeneration. Akkermansia muciniphila (A. muciniphila) is an anaerobic bacterium found in the mucin layer of the intestinal microbiota. It has been found that the population of A. muciniphila decreases in the case of different diseases. In light of this information, the curative effect of A. muciniphila application on colitis-induced inflammation and enteric degeneration was investigated. METHODS In this study, 5 weeks of A. muciniphila treatment in Trinitro-benzene-sulfonic acid (TNBS)-induced chronic colitis model was investigated. Colon samples were examined at microscopic, biochemical, and molecular levels. Fecal samples were collected before, during, and after treatment to evaluate the population changes in the microbiota. Specific proteins secreted from the ENS were evaluated, and enteric degeneration was examined. RESULTS As a result of the research, the ameliorative effects of A. muciniphila were shown in the TNBS colitis model-induced inflammation and ENS damage. DISCUSSION In light of these results, A. muciniphila can potentially be evaluated as a microbiome-based treatment for IBD with further clinical and experimental studies.

Wu D, Zhang Y, Zou B, Lu Y, Cao H. Shaoyao decoction alleviates TNBS-induced ulcerative colitis by decreasing inflammation and balancing the homeostasis of Th17/Treg cells. BMC Complement Med Ther 2023; 23:424. [PMID: 38001450 PMCID: PMC10668496 DOI: 10.1186/s12906-023-04237-9] [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: 02/05/2023] [Accepted: 10/29/2023] [Indexed: 11/26/2023] Open
Abstract
BACKGROUND Ulcerative colitis (UC) is a persistent and non-specific inflammatory condition that mainly affects the bowels and has challenging treatment. UC has a growing incidence and significantly affects the well-being of patients. Many medications used to treat UC can disrupt the metabolism and immune system homeostasis, frequently leading to significant adverse effects. Hence, exploring alternative therapies, such as traditional Chinese medicine and probiotics, has recently emerged as a primary research hotspot owing to their safety. Although the therapeutic mechanism of Shaoyao decoction has not been clarified, it has demonstrated a beneficial clinical effect on UC. AIM This study aimed to assess the effect of Shaoyao decoction on a rat model of UC and investigate its underlying mechanisms. METHODS The rat model of UC was induced by 2,4,6-trinitrobenzenesulfonic acid (TNBS). The extent of damage to the intestines was assessed using the disease activity index (DAI), colonic mucosa damage index (CMDI), and histological scores. Immunohistochemistry was employed to detect the tissue levels of interleukin (IL)-17, transforming growth factor (TGF)-β1, and IL-10. Additionally, the proportion of Th17 and Treg cells was detected using flow cytometry. In colon tissue, the levels of forkhead box (Fox)p3, RAR-related orphan receptor (ROR)γt, IL-6, p-STAT3, and STAT3 proteins were quantified by Western blotting. RESULTS Treatment with Shaoyao decoction enhanced the overall health of rats and reduced colonic damage. Additionally, Shaoyao decoction significantly alleviated the severity of DAI, CMDI, and HS. The proportion of Th17 cells was reduced, and the proportion of Treg cells was increased by Shaoyao decoction. The expression of IL-17 and RORγt was suppressed by Shaoyao decoction, while the expression of IL-10, TGF-β1, and Foxp3 was increased. The expression of IL-6, p-STAT3, and STAT3 was decreased by Shaoyao decoction. CONCLUSION The Shaoyao decoction alleviates the symptoms of TNBS-induced UC by decreasing inflammation and mitigating intestinal damage while preserving the balance between Th17 and Treg. Shaoyao decoction modulates the IL-6/STAT3 axis, thereby regulating the balance between Th17 and Treg cells.

Abstract
Tryptophan (Trp) is an essential amino acid that can be metabolized via endogenous and exogenous pathways, including the Kynurenine Pathway, the 5-Hydroxyindole Pathway (also the Serotonin pathway), and the Microbial pathway. Of these, the Microbial Trp metabolic pathways in the gut have recently been extensively studied for their production of bioactive molecules. The gut microbiota plays an important role in host metabolism and immunity, and microbial Trp metabolites can influence the development and progression of various diseases, including inflammatory, cardiovascular diseases, neurological diseases, metabolic diseases, and cancer, by mediating the body's immunity. This review briefly outlines the crosstalk between gut microorganisms and Trp metabolism in the body, starting from the three metabolic pathways of Trp. The mechanisms by which microbial Trp metabolites act on organism immunity are summarized, and the potential implications for disease prevention and treatment are highlighted.

Abstract
OBJECTIVE Paeonia lactiflora Pall has long been recognized as an anti-inflammatory traditional Chinese herbal medicine. We aimed to study the pharmacological action of albiflorin, an active ingredient extracted from the roots of Paeonia lactiflora Pall, on diabetic vascular complications. METHODS Human umbilical vein endothelial cells (HUVECs) were stimulated with high glucose and treated with 5, 10, and 20 μM albiflorin. CCK-8 assay, EdU staining, Annexin V-FITC staining, transwell assay, scratch test, RT-PCR, ELISA, Western blot, and immunofluorescence were carried out. SwissTargetPrediction database was used for screening targets of albiflorin and molecular docking was done using Autodock Vina software. RESULTS Albiflorin treatment dose-dependently alleviated high glucose-induced viability loss of HUVECs. In addition, albiflorin promoted the proliferation and migration, while inhibited apoptosis and the release of TNF-α, IL-6, and IL-1β in HUVECs. PARP1 was predicted and confirmed to be a target for albiflorin in vitro. Albiflorin targeted PARP1 to inhibit the activation of NF-κB. Transfection of HUVECs with PARP1 overexpression plasmids effectively reversed the effects of albiflorin on high glucose-treated HUVECs. CONCLUSIONS Albiflorin suppressed high glucose-induced endothelial cell apoptosis and inflammation, suggesting its potential in treating diabetic vascular complications. The action of albiflorin possibly caused by its regulation on inhibiting PARP1/NF-κB signaling.

Abstract
This study aimed to compare the differences between oral administration and intravenous injection of polygalacturonic acid (PGA) in the regulation of immune and intestinal microflora in ulcerative colitis (UC) mice. PGA was administered orally or intravenously. PGA in the high-dose ig group was the most effective in treating UC by increasing colon length and downregulating disease activity index, histopathological score and proinflammatory cytokine levels. In spleen, the efficacy of PGA on restoring Th17/Treg balance in the high-dose iv group was better than that in the high-dose ig group, the opposite was observed in the lamina propria. The level of colonic IL-17A in the high-dose ig group was lower than that in the high-dose iv group, the opposite was observed for that of colonic IL-10. Western blot and immunohistochemistry analysis revealed that PGA in the high-dose ig group decreased the protein expression of RORγt, and increased that of FOXP3. Furthermore, PGA in the high-dose ig group was more effective than that in the high-dose iv group in improving the intestinal microflora structure. Our results suggest that in immune regulation, oral PGA is more effective in the lamina propria and gut microbiota while intravenous PGA is more effective in the spleen.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 102:154202. [PMID: 35665678 DOI: 10.1016/j.phymed.2022.154202] [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: 03/02/2022] [Revised: 05/17/2022] [Accepted: 05/22/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Inflammatory bowel disease (IBD) is a chronic nonspecific inflammatory disease that causes a heavy burden and lacks effective treatments. Chinese herbal medicine prescriptions (CHMPs), which are characterized by a synergistic usage of herbs, are widely used in the management of IBD. The molecular mechanisms of action of CHMP are still ambiguous as the canonical "one-compound-one-target" approach has difficulty describing the dynamic bioreactions among CHMP objects. It seems more flexible to define the holism of CHMP for IBD by employing high-throughput analysis. However, studies that discuss the development of CHMP in treating IBD in a holistic view are still lacking. PURPOSE This review appraised preclinical and clinical research to fully describe the anti-IBD capacity of CHMPs and discussed CHMPs' holistic characteristics that can contribute to better management of IBD. METHODS & RESULTS We screened clinical and preclinical references of CHMP being used as treatments for IBD. We discussed the complexity of IBD and the development of CHMP to present the sophistication of CHMP treatments. To describe the clinical effectiveness of CHMPs against IBD, we performed an umbrella review of CHMP-associated META analyses, in which 1174 records were filtered down to 12 references. Then, we discussed 14 kinds of CHMPs that had a long history of use and analyzed their mechanisms of action. Representative herbs were employed to provide a subordinate explanation for the whole prescription. As holism is the dominant characteristic of CHMPs, we explored applications of CHMPs for IBD with the help of omics, gut microbiome, and network pharmacology, which are potential approaches to a dynamic figure of bioactions of CHMPs. CONCLUSION This review is the first to discuss the potential of CHMPs to manage IBD in a holistic context and will provide inspiring explanations for CHMP applications for further product transformation and application to other diseases.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is a chronic idiopathic disease that is characterized by inflammation of the gastrointestinal tract. Proper management of IBD requires both early diagnosis and novel therapies and management programs. Many reports have suggested that Chinese medicine has unique properties favorable to the treatment of IBD. However, there are no systematic analyses on this topic. PURPOSE This review summarizes recent studies that assessed the effects and mechanisms of Chinese medicine in the treatment of IBD in order to fully understand the advantages of Chinese medicine in the management of IBD. METHODS A literature search was conducted using peer-reviewed and clinical databases, including PubMed, Web of Science, ClinicalTrials.gov, MEDLINE, EMBASE, Springer LINK, Wan-fang database, the Chinese Biomedicine Database, and the China National Knowledge Infrastructure (CNKI). Keywords used were inflammatory bowel disease (including Ulcerative colitis or Crohn's disease) and Chinese medicine. All selected articles were from 1997 to 2021, and each were assessed critically for our exclusion criteria. Studies describing the pathogenesis of IBD, the effects and mechanisms of Chinese medicine in the treatment of IBD, in particular their roles in immune regulation, intestinal flora regulation, and improvement of intestinal barrier function, were included. CONCLUSION This review highlights recent progress in the use of Chinese medicine in the treatment of IBD. It also provides a reference for further evaluation and exploration of the potential of classical multi-herbal Chinese medicine in the treatment of IBD.

Abstract
AIMS Whether dextran sodium sulfate (DSS)-induced ulcerative colitis (UC) animal models undergo self-healing remains unclear. Therefore, the study aim was to determine if these models have self-healing ability. MAIN METHODS UC was induced using 4% DSS in male KM mice. Histopathological and inflammatory cytokine were evaluated. Fecal samples were analyzed by 16S rDNA gene sequencing. KEY FINDINGS Physiological and inflammatory cytokine changed obviously on days 4-14 of establishment and returned to normal levels by day 21. The degrees of inflammation and injury in pathological sections decreased within 14 days compared with those on day 7. Interleukin (IL)-17A, IL-6, and C-reactive protein (CRP) levels fluctuated daily and were highest at 10 AM, 11 AM, and 8 PM, respectively. Intestinal flora disturbance was most obvious on days 7 and 14. The abundances of Lactobacillus and Alistipes decreased, whereas those of Streptococcus, Escherichia-Shigella, and Oscillibacter increased and mostly recovered by day 21. Lactobacillus and serum CRP level were negatively correlated with inflammation, whereas Streptococcus and Escherichia-Shigella were positively correlated with serum IL-6 level. SIGNIFICANCE The DSS-induced UC murine model was shown to undergo self-healing. Intestinal flora disturbance in the model were obvious from days 4 to 14 and had mostly recovered by day 21.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Inflammatory bowel disease (IBD) is one of the most common chronic inflammatory illnesses of the gastrointestinal tract due to the imbalance of immune homeostasis of T helper cells and/or regulatory T cells (Tregs). The Traditional Chinese medicine herb has been clinically proven for use in the treatment of IBD but its possible mechanism remains unknown. The study aims to assess the effect of Chinese medicinal herb decoction QRZSLXF (Qing Re Zao Shi Liang Xue receipt) for the treatment of TNBS-induced experimental colitis in mice and explore its relevant mechanism involved in Th17 and Tregs. MATERIALS AND METHODS Mice colitis was induced by 50% 2,4,6-Trinitrobenzenesulfonic Acid (TNBS) ethanol solution weekly manner. These established model mice were divided into model control (0.8% NaCl treatment), FICZ, naphthoflavone (NaFTV), dexamethasone (DXM), and QRZSLXF (QrLx) groups. The colonoscopy, H&E staining, and immune staining were used to analyze the disease severity, inflammatory condition and Th17 or Treg related factors expression. High-performance liquid chromatography-mass spectrometry (HPLC/MS) was used to assess the content of FICZ in the colon tissues. Western blot and ELISA were used to examine the expression of Th17 or Treg related factors protein levels. Flow cytometry analysis was performed to assess the number and ratio of Th17/Tregs in splenocytes, and mesenteric lymph node lymphocytes (MLNCs), and lamina propria mononuclear cells (LPMCs). RESULTS NaFTV, DXM and QrLx groups intestinal inflammation scores were significantly lower than that in colitis model control and FICZ groups, while the IL-6, STAT3, and RORγt expression levels were significantly lower than those in the model control and FICZ groups. Mass spectrometry results showed FICZ that in both DXM and QrLx groups was lower than control model and FICZ groups. Flow cytometry results showed that DXM, NaFTV and QrLx could significantly reduce Th17 proportion and increase Treg proportion in splenocytes, MLNCs, and LPMCs. CONCLUSIONS NaFTV and QrLx treatment could decrease symptoms and inflammatory colitis, by decreasing of FICZ concentration and AhR signaling in colon, resulting in reducing the expression of IL-6, STAT3, and RORγt, whereas increasing the expression of FOXP3, consequently reducing the proportion of Th17 cells and increasing the proportion of Treg cells, respectively.

OBJECTIVE To investigate the effects of total glucosides of paeony (TGP) on the proliferation and activation-induced cell death of mouse T cells and the mechanism underlying the immunosuppressive effects of TGP. METHODS Purified total T cells isolated from the spleen of C57BL/6 mice were treated with TGP at 0, 50, 100, or 200 μg/mL and stimulated by anti-CD3/ CD28. Flow cytometry was performed to detect the cell death and the proliferation of CFSE-labeled T cells. The expression of Fas/FasL mRNA was detected using RT-PCR, and flow cytometry was used to analyze the expression of Fas/FasL proteins on activated T cells. Western blotting was used to detect the expression of Bcl-2 in the cells. RESULTS TGP treatment for 48 h significantly reduced the total number and percentage of viable T cells and dose-dependently lowered the percentage of divided T cells. TGP treatment obviously up-regulated the cellular expression of Fas mRNA, enhanced Fas expression on the surface of the T cells, and decreased the expression level of Bcl-2 protein in the cells. CONCLUSIONS TGP significantly inhibits proliferation and promotes activation-induced cell death of mouse T cell by increasing the expression of Fas and downregulating the expression of Bcl-2.

Indole-3-carbinol prevents colitis and associated microbial dysbiosis in an IL-22-dependent manner. JCI Insight 2020; 5:127551.

Abstract
Colitis, an inflammatory bowel disease, is caused by a variety of factors, but luminal microbiota are thought to play crucial roles in disease development and progression. Indole is produced by gut microbiota and is believed to protect the colon from inflammatory damage. In the current study, we investigated whether indole-3-carbinol (I3C), a naturally occurring plant product found in numerous cruciferous vegetables, can prevent colitis-associated microbial dysbiosis and attempted to identify the mechanisms. Treatment with I3C led to repressed colonic inflammation and prevention of microbial dysbiosis caused by colitis, increasing a subset of gram-positive bacteria known to produce butyrate. I3C was shown to increase production of butyrate, and when mice with colitis were treated with butyrate, there was reduced colonic inflammation accompanied by suppression of Th17 and induction of Tregs, protection of the mucus layer, and upregulation in Pparg expression. Additionally, IL-22 was increased only after I3C but not butyrate administration, and neutralization of IL-22 prevented the beneficial effects of I3C against colitis, as well as blocked I3C-mediated dysbiosis and butyrate induction. This study suggests that I3C attenuates colitis primarily through induction of IL-22, which leads to modulation of gut microbiota that promote antiinflammatory butyrate.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2019; 62:152940. [PMID: 31100680 DOI: 10.1016/j.phymed.2019.152940] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/26/2018] [Revised: 03/29/2019] [Accepted: 04/22/2019] [Indexed: 06/09/2023]
Abstract
BACKGROUND Psoriasis is a common chronic relapsing immune-mediated inflammatory disease, the prevalence of which has increased in recent years. At present, there are many treatment methods available for the condition, but the curative effect is unsatisfactory. HYPOTHESIS/PURPOSE This study aimed to evaluate the efficacy, adverse reactions, and recurrence rates of using paeoniflorin capsules for psoriasis treatment. STUDY DESIGN systematic review and meta-analysis. METHODS Randomized controlled trials comparing total glycosides of paeony (TGP) with other treatments for patients with psoriasis were retrieved by searching EMBASE, MEDLINE, and the Cochrane Central Register of Controlled Trials electronic databases. Cochrane bias risk tool was used to evaluate the quality of randomized controlled trial (RCT) methodology. The primary outcome measure is the effective number. Secondary outcomes included psoriasis area and severity index (PASI), adverse reactions, recurrence, and inflammatory biomarkers. RESULTS In all, 30 RCTs with 2,802 participants were included in this meta-analysis. The studies were generally of low methodological quality. Although there was no statistically significant difference between the use of TGP capsule alone and other monotherapies in the treatment of psoriasis (RR: 0.93; 95% CI: 0.76-1.15; p = 0.50), the addition of TGP to other therapies had an advantage over monotherapy with regard to the effective number (RR: 1.31; 95% CI: 1.26-1.37; p < 0.00001), PASI (RR: -3.40; 95% CI: -4.22,-2.57; p < 0.00001), adverse reactions, recurrence rate (RR: 0.42; 95% CI: 0.24-0.74; p = 0.002), and inflammatory inhibition (RR:-12.54; 95% CI: -18.50, -6.59; p < 0.0001). CONCLUSIONS TGP can be used to treat psoriasis with reduced adverse reactions and recurrence rates. However, the mechanism of TGP in psoriasis treatment requires to be evaluated further in high-quality, large-sample, and rigorous clinical studies.
