ENVIRONMENTAL TOXICOLOGY 2023; 38:2595-2607. [PMID: 37466184 DOI: 10.1002/tox.23895] [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: 12/01/2022] [Revised: 05/31/2023] [Accepted: 07/01/2023] [Indexed: 07/20/2023]
Abstract
BACKGROUND Exosomes are applied as biomarkers in several diseases according to their disease-specific profiles. However, the exosomes effects in functional dyspepsia (FD) are still fragmentary. Here we examined the role of Eosinophil and mast cell derived-exosomes in FD progression. METHODS Fifty FD subjects and age- and sex-matched healthy controls were included in this retrospective cohort study. Duodenal mucosa and gastric juice were collected to analyze molecular difference. Eosinophil and mast cell were evaluated by immunofluorescence and microarray was subjected to examine the expression levels of NEAT1, miR-211-5p, and glial cell line-derived neurotrophic factor (GDNF), which were subsequently were tested by quantitative reverse transcription PCR (RT-qPCR) validation cohorts. CCK-8 assays, and wound healing assays were used to evaluate integrity of intestinal mucosal barrier in vitro. Rats' weights and gastric emptying rates were used as evaluation of FD severity in vivo. RESULTS Eosinophil and mast cell were enriched and secreted more exosomes in duodenal mucosa of FD patients. We identified differential lncRNAs that were consistently and significantly up regulated in FD cases. Of these, NEAT1 was further validated by RT-qPCR and had closely relationship with GDNF. MiR-211-5p level was found to be reduced in FD and negatively related with NEAT1 and GDNF. Furthermore, NEAT1and GDNF relived FD while miR-211-5p made symptoms worse. The NEAT1/miR-211-5p/GDNF axis had a good predictive ability for FD. CONCLUSIONS The NEAT1/miR-211-5p/GDNF could be a potential FD biomarker.

Systems biology strategy through integrating metabolomics and network pharmacology to reveal the mechanisms of Xiaopi Hewei Capsule improves functional dyspepsia. J Chromatogr B Analyt Technol Biomed Life Sci 2023; 1226:123676. [PMID: 37329776 DOI: 10.1016/j.jchromb.2023.123676] [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: 11/26/2022] [Revised: 03/05/2023] [Accepted: 03/13/2023] [Indexed: 06/19/2023]
Abstract
Functional dyspepsia (FD) is one of the more common functional disorders, with a prevalence of 20-25 %. It seriously affects the quality life of patients. Xiaopi Hewei Capsule (XPHC) is a classic formula originated from the Chinese Miao minority. Clinical studies have demonstrated that XPHC can effectively alleviate the symptoms of FD, but the molecular mechanism has not been elucidated. The purpose of this work is to investigate the mechanism of XPHC on FD by integrating metabolomics and network pharmacology. The mice models of FD were established, and gastric emptying rate, small intestine propulsion rate, serum level of motilin and gastrin were evaluate to study the interventional effect of XPHC on FD. Next, a metabolomics strategy has been developed to screen differential metabolites and related metabolic pathways induced by XPHC. Then, prediction of active compounds, targets and pathways of XPHC in treating FD were carried out by commonly used network pharmacological method. Finally, two parts of the results were integrated to investigate therapeutic mechanism of XPHC on FD, which were preliminary validated based on molecular docking. Thus, twenty representative different metabolites and thirteen related pathways of XPHC in treating FD were identified. Most of these metabolites were restored using modulation after XPHC treatment. The results of the network pharmacology analysis showed ten crucial compounds and nine hub genes related to the treatment of FD with XPHC. The further integrated analysis focused on four key targets, such as albumin (ALB), epidermal growth factor receptor (EGFR), tumor necrosis factor (TNF) and roto-oncogene tyrosine-protein kinase Src (SRC), and three representative biomarkers such as citric acid, L-leucine and eicosapentaenoic acid. Furthermore, molecular docking results showed that ten bioactive compounds from XPHC have good binding interactions with the four key genes. The functional enrichment analysis indicated that the potential mechanism of XPHC in treating FD was mainly associated with energy metabolism, amino acid metabolism, lipid metabolism, inflammatory reactions and mucosal repair. Our work confirms that network pharmacology-integrated metabolomics strategyis a powerful means to reveal the therapeutic mechanisms of XPHC improves FD, which contribute its further scientific research.

Interpretation of a Quantitative Diagnosis Model of Traditional Chinese Medicine Syndromes Based on Computer Adaptive Testing. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:3203158. [PMID: 35815272 PMCID: PMC9262526 DOI: 10.1155/2022/3203158] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/23/2021] [Revised: 03/06/2022] [Accepted: 06/09/2022] [Indexed: 11/24/2022]
Abstract
Objectives The aim of this study is to interpret a quantitative diagnosis model of traditional Chinese medicine (TCM) syndromes based on computer adaptive testing (CAT), from the perspective of both patients and clinicians. Methods In this cross-sectional study, patients with postprandial distress syndrome completed the CAT model of TCM syndromes and the Chinese version of the Quality of Life Questionnaire for Functional Digestive Disorders (Chin-FDDQL); the clinicians' diagnosis was concurrently recorded. The patients completed this questionnaire again after 14 ± 2 days. The kappa test and paired chi-square test were used to evaluate the consistency between the CAT model and clinical diagnosis. Minimal clinically important differences (MCID) of the Chin-FDDQL scores were used to assess clinical efficacy from the patients' perspective. Logistic regression was used to examine the association between changes in the CAT model syndrome domain scores and changes in clinical outcomes. Results Changes in the CAT model syndrome domain scores may affect the clinical outcomes of patients with the total scores of Chin-FDDQL (all P < 0.05). There was a correlation between changes in the CAT model syndrome domain scores and the patients' clinical outcomes. Different syndrome elements had different effects on various Chin-FDDQL domains, which was consistent with the theory of TCM. Conclusions This study proposes a method for the clinical interpretation of the CAT model of TCM syndromes, including evidence derived from the application. It may provide a reference for future interpretation of other CAT models.

Clinical Effect of Acupuncture Combined with Traditional Chinese Medicine Application on the Treatment of Functional Dyspepsia in Children and the Influence on Serum 5-HT and NO Levels. COMPUTATIONAL INTELLIGENCE AND NEUROSCIENCE 2022; 2022:6800662. [PMID: 35401711 PMCID: PMC8989592 DOI: 10.1155/2022/6800662] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/25/2022] [Revised: 03/15/2022] [Accepted: 03/21/2022] [Indexed: 12/29/2022]
Abstract
Objective To explore the clinical effect of acupuncture combined with traditional Chinese medicine (TCM) application on the treatment of functional dyspepsia (FD) in children and the influence on serum 5-HT and NO levels. Methods 94 FD children admitted to the pediatric department of our hospital from March 2019 to March 2020 were selected as the research object and divided into the study group (n = 45) and reference group (n = 49) by the number table method. The routine Western medicine therapy was given to the reference group and the combination therapy of acupuncture and TCM application was given to the study group to analyze the effect of different therapies on FD children by detecting their serum 5-hydroxytryptamine (5-HT) and nitric oxide (NO) levels and electrogastrogram (EGG) before and after treatment. Results The sex ratio, mean age, mean duration of disease, mean weight, mean BMI value, and residence of children in the two groups were not significantly different (P > 0.05); after treatment, the study group obtained significantly lower symptom scores and shorter disappearance time of clinical symptoms when comparing with the reference group (P < 0.001); the total clinical effective rate of the study group was significantly higher than that of the reference group (P < 0.05); the treated serum 5-HT and NO levels of children in both groups were significantly lower than those before treatment (P < 0.05), and in the between-group comparison, those of the study group were significantly lower (P < 0.05); and the treated AP, FP, and normal slow wave ratio of gastric antrum and body were significantly higher in the study group than in the reference group (P < 0.05). Conclusion The combination therapy of acupuncture and TCM application is a reliable method for improving the clinical symptoms in FD children. This strategy greatly reduces the levels of serum factors in child patients and shortens the corresponding treatment time. Further research will be conducive to establishing a better solution for such patients.

Abstract
PURPOSE OF REVIEW Traditional Chinese medicine (TCM) has been in use for thousands of years in Asian countries and is rapidly gaining popularity in the Western world. Among different forms of TCM, the traditional Chinese herbal therapy and acupuncture are the most popular modalities. Here, we review the fundamentals of TCMs for clinicians practicing in the West and will also detail the evidence-based utility of Chinese herbal medicine in the management of functional gastrointestinal disorders (FGIDs). RECENT FINDINGS In the recent decades, the popularity and usage of traditional Chinese herbal medicine in FGIDs is increasing in the West. TCMs are commonly utilized by many patients with FGIDs as the conventional therapies do have limitations such as cost, inadequate symptom control and adverse effects. The unfamiliarity of TCM philosophy among clinicians in the West, and shortage of traditional Chinese herbalists remain. The philosophy of TCM is complex and entirely different from the Western medical concepts and is difficult to understand for a clinician trained in the West. Further traditional Chinese herbal therapies are often viewed skeptically by the clinicians in the West for various reasons such as lack of scientific rigor, inconsistencies in the constituents of herbal products, and also concerns due to adverse herb effects. Future clinical trials in FGIDs should focus on herb product quality, herb-drug interactions, and standardized criteria for diagnosis and management outcomes.

Mechanisms Underlying the Action of Ziziphi Spinosae Semen in the Treatment of Insomnia: A Study Involving Network Pharmacology and Experimental Validation. Front Pharmacol 2022; 12:752211. [PMID: 35002696 PMCID: PMC8740267 DOI: 10.3389/fphar.2021.752211] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Accepted: 11/25/2021] [Indexed: 01/13/2023] Open
Abstract
Purpose: This study aimed to investigate the potential mechanisms and related bioactive components of ZSS for the treatment of insomnia. Method: The insomnia model of rat induced by PCPA was established. After oral administration of ZSS extract, the general morphological observation, pentobarbital sodium-induced sleep test and histopathological evaluation were carried out. Network pharmacology, assisted by UHPLC-Q-Exactive-MS/MS analysis, was developed to identify the targets of ZSS in the treatment of insomnia, as well as the corresponding signaling pathways. In addition, we validated the identified targets and pathways by RT-qPCR and immunohistochemical analysis. Results: The pentobarbital sodium-induced sleep test, determination of 5-HT and GABA levles in hypothalamic tissues and HE staining showed that ZSS extract was an effective treatment for insomnia. Network pharmacology analysis identified a total of 19 candidate bioactive ingredients in ZSS extract, along with 433 potentially related targets. Next, we performed protein-protein interaction (PPI), MCODE clustering analysis, GO functional enrichment analysis, KEGG pathway enrichment analysis, and ingredient-target-pathway (I-T-P) sub-networks analysis. These methods allowed us to investigate the synergistic therapeutic effects of crucial pathways, including the serotonergic and GABAergic synapse pathways. Our analyses revealed that palmitic acid, coclaurine, jujuboside A, N-nornuciferine, caaverine, magnoflorine, jujuboside B, and betulinic acid, all played key roles in the regulation of these crucial pathways. Finally, we used the PCPA-induced insomnia in rats to validate the data generated by network pharmacology; these in vivo experiments clearly showed that pathways associated with the serotonergic and GABAergic system were activated in the rats model. Furthermore, ZSS treatment significantly suppressed high levels of HTR1A, GABRA1, and GABRG2 expression in the hypothalamus and reduced the expression levels of HTR2A. Conclusion: Based on the combination of comprehensive network pharmacology and in vivo experiments, we successfully identified the potential pharmacological mechanisms underlying the action of ZSS in the treatment of insomnia. The results provide a theoretical basis for further development and utilization of ZSS, and also provide support for the development of innovative drugs for the treatment of insomnia.

Abstract
Gastrointestinal disorder (GID) is a global health disease which leads to heavy public medical burden. Disorders in the intestinal flora have been found in gastrointestinal disorder patients. However, the interaction between GID and the intestinal flora in faecal has not been studied comprehensively. In addition, multicomponent drugs represented by traditional Chinese medicine (TCM) are widely used for treating GID, but their modulation of the intestinal flora has not been investigated. Therefore, in this study, a high-throughput sequencing strategy was used to investigate alterations in the intestinal flora in a rat GID model, followed by an investigation of the modulation by a representative TCM, Xiaoerfupi (XEFP) granule. The results showed that in rats with GID, the relative abundances of Erysipelotrichaceae, Lachnospiraceae, Streptococcaceae increased and that of Ruminococcaceae decreased. At the macro level, the levels of LysoPC(16:0), LysoPC(20:2), LysoPC(15:0), LysoPC(20:2 (11Z, 14Z)), LysoPC(20:1), LysoPC(15:0), LysoPC(20:0) and LysoPE (0:0/20:0) in serum increased and levels of PC(36:4), PC(38:4), PC(o-36;4), PE (MonoMe(13,5)/MonoMe(11,5)) decreased. The imbalance of metabolites was restored by XEFP through ether lipid metabolism pathway. Increase in the phyla Firmicutes/Bacteroidetes (F/B) ratio of the GID rats was restored by XEFP as well. Moreover, XEFP can relief the symptoms of GID rats by increasing bacteria Ruminococcaceae and decreasing Streptococcaceae, Erysipelotrichaceae and Lachnospiraceae in faecal microbiota level. This study represents a comprehensive survey of the interaction between GID and the intestinal flora and a systematic evaluation of modulation by a multicomponent drug.

JOURNAL OF ETHNOPHARMACOLOGY 2021; 275:114119.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE WeiChang'An Pill (WCAP) is used in Traditional Chinese Medicine (TCM) to clinically treat diarrhoea-predominant irritable bowel syndrome (IBS-D); however, the underlying pharmacological mechanisms are unclear to date. AIM OF THE STUDY To explore the mechanism underlying the therapeutic action of WCAP in IBS-D using a network pharmacology approach and in vivo experiments. MATERIALS AND METHODS The active compounds of WCAP were selected from the TCM Systems Pharmacology Database and TCM Integrated Database, and the potential targets were identified using the Swiss Target Prediction and Similarity Ensemble Approach (SEA) databases. The targets related to IBS-D were mined from the Therapeutic Target Database (TTD), National Center for Biotechnology Information Search database (NCBI), DrugBank database, and DisGeNET database. The intersecting protein-protein interactions (PPIs) of the drug-disease crossover genes were analysed, and the central PPI network was constructed using the String database, version 11.0, and Cytoscape version 3.7.2. Following Gene Ontology and Kyoto Encyclopaedia of Genes and Genomes pathway analyses, the gene-pathway network was constructed for identifying the key target genes and pathways. Based on the results and existing evidence, it was selected the cyclic adenosine monophosphate (cAMP) signalling pathway for further validation using in vivo experiments. RESULTS A total of 872 targets were identified from the 77 active compounds in WCAP, which shared 78 targets that were predicted to be related to IBS-D. Twenty-one core targets were identified from the PPI network, which was constructed from the common targets. The results of enrichment analysis revealed that HRT2B, ADRA1A, ADRA1D, and CHRM2 could be the key targets of WCAP in IBS-D, and 11 signalling pathways, including the neuroactive ligand-receptor interaction, calcium signalling, and cAMP signalling pathways, were identified as crucial for the therapeutic activity of WCAP in IBS-D. We also identified the possibility of several interactions and crosstalk between the different pathways. Subsequent molecular biology experiments revealed that the expression levels of cAMP, phospho-(Ser/Thr) protein kinase A substrates (p-PKA), 5-hydroxytryptamine, and proteins in the cAMP signalling pathway, including G protein-coupled receptor (GPCR), adenylyl cyclase 5 (AC5), and cAMP-response element binding protein (CREB), were significantly upregulated in rat models of IBS-D following treatment with WCAP (P < 0.05). However, a reverse trend was observed in the expression of nuclear factor kappa-B (NF-κB) (P < 0.05), which could be attributed to the low-grade inflammation that occurs in IBS-D. CONCLUSION We demonstrated that WCAP may alleviate the symptoms of diarrhoea and visceral sensitivity in IBS-D by regulating the cAMP signalling pathway.

Effect of Artemisia rupestris L. Extract on Gastrointestinal Hormones and Brain-Gut Peptides in Functional Dyspepsia Rats. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2020; 2020:2528617. [PMID: 33281909 PMCID: PMC7685828 DOI: 10.1155/2020/2528617] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/30/2020] [Revised: 10/14/2020] [Accepted: 10/24/2020] [Indexed: 12/26/2022]
Abstract
Artemisia rupestris L. is the perennial herb of rupestris belonging to Artemisia (Compositae), which is wildly distributed in Xinjiang (China), middle Asia, and Europe. It is known to have anti-inflammatory, hepatoprotective, immune function regulation, and gastrointestinal function regulation effects. AR is used to treat digestive diseases, but the effects of AR on antifunctional dyspepsia (FD) activity have not yet been reported. In this study, we aimed to investigate the therapeutic effects of Artemisia rupestris L. extract (ARE) on gastrointestinal hormones and brain-gut peptide in functional dyspepsia (FD) rats. Sixty Sprague-Dawley rats were randomly divided into 6 groups. An FD rat model was established by irregular tail clamp stimulation for 14 days except the blank group. After FD rat models, the blank group and model group were given menstruum, and the medicated rats were given corresponding medicine for 14 days. The general observations, bodyweight, and food intake were observed, and the content of serum gastrin (GAS), plasma motilin (MTL), plasma vasoactive intestinal peptide (VIP), and plasma somatostatin (SS) by the enzyme-linked immunosorbent assay was observed. The content of plasma VIP and plasma SS in the ARE group was significantly lower than in the model group, and the content of serum GAS and plasma MTL was increased in the ARE group; the GAS expression of antrum and hypothalamus was increased in the ARE group, and SS expression of antrum and hypothalamus was decreased in the ARE group by immunohistochemical detection; the results of semiquantitative reverse transcription polymerase chain reaction (RT-PCR) indicate that ARE inhibits the mRNA expression of VIP. Our results suggest that ARE can recover gastrointestinal hormone levels and regulation of the peripheral and central nervous system and alter gut peptide levels, which confirm the therapeutic effect of ARE on functional dyspepsia.

TR-DH (TD) is a traditional Chinese medicine herb pair that promotes blood circulation and removes blood stasis. In recent years, TD has shown definite benefits in the cardio-cerebrovascular system, but its specific mechanism is not very clear. AIM OF STUDY The purpose of this study was to explore the mechanism by which TD affects cerebral ischaemia/reperfusion (I/R) injury and to optimize the mixture ratio. METHODS The affected metabolic pathways in rat brain tissues after I/R were analysed by network pharmacology and verified with animal pharmacological experiments. RESULTS TD had a certain therapeutic effect on cerebral I/R injury. TD with a TR:DH ratio of 1:1 had the best therapeutic effect. Metabolic pathway analysis showed that the protective mechanism of TD against I/R injury involves mainly regulation of brain tissue ADORA2A protein levels and action on the arachidonic acid (AA) pathway. CONCLUSION TD can ameliorate cerebral I/R injury by regulating ADORA2A degradation in the AA metabolic pathway to attenuate AA metabolic dysfunction and the inflammatory response.

Abstract
Background At certain frequencies, abdominal naprapathy effectively alleviates functional dyspepsia with spleen deficiency. The present study explored the effects of various frequencies of abdominal naprapathy on gastrointestinal mucosal cells in spleen-deficient rabbits. Material/Methods The model of spleen deficiency was established by the method of bitter cold and catharsis. The rabbits were treated with various frequencies (50–100 and 201–250 vibrations/min) of abdominal naprapathy. Results In model rabbits, gastrointestinal mucosal thickness was changed, mucosal epithelial cells were necrotic significantly, a large number of inflammatory cells were infiltrated, and duodenal villus were destroyed. The gastrointestinal mucosal cells had different degrees of regeneration and remodeling under various frequencies of abdominal naprapathy intervention. Among them, the abdominal naprapathy with manipulation frequency of 101–150 times/min showed the best effect. Conclusions The abdominal naprapathy, especially with frequency of 101~150 times/min, repairs gastrointestinal mucosal injury of spleen-deficiency rabbits.
