JOURNAL OF ETHNOPHARMACOLOGY 2024; 337:118926. [PMID: 39393559 DOI: 10.1016/j.jep.2024.118926] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/21/2024] [Revised: 10/03/2024] [Accepted: 10/08/2024] [Indexed: 10/13/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The prevalence of gastrointestinal motility disorders (GMD) is increasing and is characterized by long-term recurrence. Citri Sarcodactylis Fructus (CSF), as a traditional Chinese medicine (TCM) known in "regulating qi and harmonizing the stomach", has therapeutic effects on GMD. However, the material basis of its efficacy is not clear. AIM OF THE STUDY The aim of this study was to evaluate the gastrointestinal motility-promoting activity of CSF extracts and to screen their active ingredients and to perform a preliminary validation. METHODS The chemical composition spectrum of different extracts of CSF were established by ultra high-performance liquid chromatography coupled with quadrupole orbitrap high-resolution mass spectrometry (UHPLC-Q/Orbitrap HRMS). The gastrointestinal motility-promoting activities of CSF were investigated by determining the intestinal propulsion rate, gastric emptying rate, acetylcholinesterase activity, and motilin content in L-arginine-induced GMD mice. Spectrum-effect relationship and network pharmacology analysis were used for the screening of potential active ingredients. A zebrafish gastrointestinal motility model traced with Nile Red was established to validate the active ingredients. Molecular docking prediction was used to explore the mechanism of action of the active ingredient. Finally, Western blotting and TUNEL staining were performed to validate the molecular docking predictions. RESULTS In total, 42 shared components were identified. The main active fraction of CSF to promote gastrointestinal motility was 70% ethanol elution fraction. Eleven potential active ingredients were screened by grey correlation analysis, orthogonal partial least squares analysis, and "active ingredient-target" network. Six compounds were confirmed as the pharmacodynamic substances of CSF by zebrafish gastrointestinal motility model, namely, quercetin, kaempferol, isorhamnetin, diosmetin, hesperetin, and 5,7,3'-trihydroxy-6,4',5'-trimethoxyflavone. Molecular docking predictions and Western blotting assays indicated that CSF may act on AKT and MMP9 targets to exert gastrointestinal motility-promoting activity. CONCLUSION This study provided a foundation for elucidating the gastrointestinal motility-promoting activity of CSF and its material basis by integrating spectrum-effect relationship and network pharmacology. It also provided a theoretical basis for quality control of CSF and a new idea for the discovery and validation of pharmacodynamic substances in TCM.

Abstract
Chronic kidney disease (CKD) affects 9.1% of the population worldwide. CKD may lead to structural and functional gastrointestinal alterations, including impairment in the intestinal barrier, digestion and absorption of nutrients, motility, and changes to the gut microbiome. These changes can lead to increased gastrointestinal symptoms in people with CKD, even in early grades of kidney dysfunction. Gastrointestinal symptoms have been associated with lower quality of life and reduced nutritional status. Therefore, there has been considerable interest in improving gastrointestinal health in this clinical population. Gastrointestinal health can be influenced by lifestyle and medications, particularly in advanced grades of kidney dysfunction. Therapies focused on gastrointestinal health have been studied, including the use of probiotics, prebiotics, and synbiotics, yielding limited and conflicting results. This review summarizes the alterations in the gastrointestinal tract structure and function and provides an overview of potential nutritional interventions that kidney disease professionals can provide to improve gastrointestinal health in individuals with CKD.

Abstract
INTRODUCTION Physiologically based pharmacokinetic (PBPK) modeling is a paradigm shift in this era for determining the exposure of drugs in pediatrics, geriatrics, and patients with chronic diseases where clinical trials are difficult to conduct. AREAS COVERED This review has collated data regarding published PBPK models on chronic kidney disease (CKD), including the drug and system-specific input model parameters and model evaluation criteria. Four databases were used from 13th June 2023 to 10th July 2023 for identifying the relevant studies that met the inclusion/exclusion criteria. Alterations in plasma protein (albumin/alpha-1 acid glycoprotein), gastric emptying time, hematocrit, small intestinal transit time, the abundance of cytochrome (CYP) 450 enzymes, glomerular filtration rate, and physicochemical parameters for different drugs were explicitly elaborated from earlier reported studies. Moreover, model evaluation depicted that models in CKD for most of the included drugs were within the allowed two-fold error range. EXPERT OPINION This review will provide insights for researchers on applying PBPK models in managing patients with different levels of CKD to prevent undesirable side effects and increase the effectiveness of drug therapy.

Abstract
AIMS Chronic kidney disease (CKD) produces multiple repercussions in the gastrointestinal tract (GIT), such as alterations in motility, gut microbiota, intestinal permeability, and increased oxidative stress. However, despite enteric glial cells (EGC) having important neural and immune features in GIT physiology, their function in CKD remains unknown. The present study investigates colonic glial markers, inflammation, and antioxidant parameters in a CKD model. MAIN METHODS A 5/6 nephrectomized rat model was used to induce CKD in rats and Sham-operated animals as a control to suppress. Biochemical measures in plasma and neuromuscular layer such as glutathione peroxidase (GPx) and superoxide dismutase (SOD) activity were carried out. Kidney histopathology was evaluated. Colon morphology analysis and glial fibrillary acid protein (GFAP), connexin-43 (Cx43), nuclear factor-kappa B (NF-κB) p65, and GPx protein expression were performed. KEY FINDINGS The CKD group exhibited dilated tubules and tubulointerstitial fibrosis in the reminiscent kidney (p = 0.0002). CKD rats showed higher SOD activity (p = 0.004) in plasma, with no differences in neuromuscular layer (p = 0.9833). However, GPx activity was decreased in the CKD group in plasma (p = 0.013) and neuromuscular layer (p = 0.0338). Morphological analysis revealed alterations in colonic morphometry with inflammatory foci in the submucosal layer and neuromuscular layer straightness in CKD rats (p = 0.0291). In addition, GFAP, Cx43, NF-κBp65 protein expression were increased, and GPx decreased in the neuromuscular layer of the CKD group (p < 0.05). SIGNIFICANCE CKD animals present alterations in colonic cytoarchitecture and decreased layer thickness. Moreover, CKD affects the enteric glial network of the neuromuscular layer, associated with decreased antioxidant activity and inflammation.

Abstract
Objective This study aimed to assess the gastric emptying capacity in nondiabetic patients with end-stage kidney disease (ESKD) by ultrasound. Methods Consecutive hemodialysis patients with ESKD (n = 37) and healthy controls (n = 37) were enrolled. All ESKD patients underwent ultrasound examinations on the day of hemodialysis (dialysis day) and the day after hemodialysis (nondialysis day). Standard ultrasound examinations were performed after overnight fasting, immediately after a light meal, and at 6 h after a meal. The antral cross-sectional area and gastric emptying according to the Perlas grading system were evaluated. Results Compared with the controls, patients with ESKD, on both dialysis and non-dialysis days, had significantly larger antral areas when examined in the supine position (p = 0.002 and p = 0.003, respectively), but not in the right lateral decubitus position (p = 0.452 and p = 0.512, respectively). In the supine position, the antral area of ESKD patients before dialysis (8 a.m. on the dialysis day) was larger than that at the same time on the nondialysis day (p = 0.028). The controls had a Perlas grade of either 0 or 1 at 6 h after a meal, whereas five patients (13.5%) and 11 patients (29.7%) in the ESKD group had Perlas grade 2 on the dialysis and non-dialysis days, respectively. Among patients with or without delayed gastric emptying, no differences were detected in the dialysis duration or levels of biochemical markers, except blood urea nitrogen (p = 0.038) and serum creatinine (p = 0.003). Conclusion Nondiabetic patients with ESKD had significantly delayed gastric emptying. Hemodialysis might improve gastric emptying and reduce gastric emptying delay.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Nowadays, gastrointestinal motility disorders (GMD) have reduced the quality of people's daily life worldwide, but there is still a lack of effective western medicine treatment. Fructus aurantii (FA), a representative regulating-qi herbal medicine, has been widely used to treat GMD in China for thousands of years, but it is not clear that which specific components contribute to the efficacy. AIM OF THE STUDY The efficacy differences of various fractions of FA on normal mice and GMD rats were compared, so as to find out the main effective fraction of FA, and to screen the main regulating-qi components based on spectrum-effect relationship and multivariate statistical analysis. MATERIALS AND METHODS The fingerprints of different fractions of FA were established and main compounds were identified with UHPLC-Q-TOF/MS technique. The promoting gastrointestinal motility activities of FA were evaluated by defecation test, gastric emptying and intestinal propulsion test in mice, and further investigated according to the biochemical analysis of 5-HT, SP, MLT, GAS and VIP in GMD rats' plasma. One-way ANOVA was used to find out the difference of efficacy. The active components were screened through spectrum-effect relationship with PCA-X, Pearson bivariate correlation analysis and OPLS analysis. CONCLUSIONS Ethyl acetate fraction is the main active fraction, and nine compounds are the major regulating-qi components. The developed spectrum-effect analysis can be used for the screening of bioactive components in natural products with high accuracy and reliability.

Abstract
The aim of this study was to analyze the prevalence of Helicobacter pylori infection and gastroduodenal lesions in Montenegrin patients with chronic kidney disease on hemodialysis. The study included 55 hemodialysis patients with dyspeptic symptoms and 50 control subjects with normal kidney function who had also dyspepsia. After dyspepsia assessment by an interview, all subjects underwent gastroduodenoscopy and histopathological analysis of biopsy specimens, taken from the corpus and antrum of the stomach. Helicobacter pylori was confirmed in 50.9% of corpus mucosa i.e. 60.6% of antrum mucosa of maintenance hemodialysis patients. There were no significantly differences in endoscopic findings of the stomach and bacterial presence between the two study groups of participants (p = 0.451), while duodenal lesions were prevalent in control subjects (p < 0.001). The atrophy of corpus mucosa was more common in hemodialysis patients (p = 0.007), especially in those who have been on hemodialysis for a longer time (p < 0.001) and had lower pH (p = 0.011). The prevalence of Helicobacter pylori infection shown an inverse relationship with dialysis duration. Contrary, a positive relationship between Helicobacter pylori and the concentration of bicarbonate was demonstrated (p = 0.031). The prevalence of Helicobacter pylori and atrophic mucosal changes in Montenegrin hemodialysis patients depends on dialysis duration and acid-base balance.

Abstract
The conventional approach to approximating the pharmacokinetics of drugs in patients with chronic kidney disease (CKD) only accounts for changes in the estimated glomerular filtration rate. However, CKD is a systemic and multifaceted disease that alters many body systems. Therefore, the objective of this exercise was to develop and evaluate a whole-body mechanistic approach to predicting pharmacokinetics in patients with CKD. Physiologically based pharmacokinetic models were developed in PK-Sim v8.0 (www.open-systems-pharmacology.org) to mechanistically represent the disposition of 7 compounds in healthy human adults. The 7 compounds selected were eliminated by glomerular filtration and active tubular secretion by the organic cation transport system to varying degrees. After a literature search, the healthy adult models were adapted to patients with CKD by numerically accounting for changes in glomerular filtration rate, kidney volume, renal perfusion, hematocrit, plasma protein concentrations, and gastrointestinal transit. Literature-informed interindividual variability was applied to the physiological parameters to facilitate a population approach. Model performance in CKD was evaluated against pharmacokinetic data from 8 clinical trials in the literature. Overall, integration of the CKD parameterization enabled exposure predictions that were within 1.5-fold error across all compounds and patients with varying stages of renal impairment. Notable improvement was observed over the conventional approach to scaling exposure, which failed in all but 1 scenario in patients with advanced CKD. Further research is required to qualify its use for first-in-CKD dose selection and clinical trial planning for a wider selection of renally eliminated compounds, including those subject to anion transport.

Abstract
Dyspepsia, one of the most prevalent diseases of the digestive tract that impacts the quality of patient life, is mainly caused by gastrointestinal motility disorder. Hawthorn is a commonly used traditional Chinese medicine for treating dyspepsia, and has been proven to improve gastrointestinal motility. Herein, a rat model of gastrointestinal motility disorder was established by subcutaneous injection with atropine. The modeled rats were treated with four polar parts (T1-4 in descending polarity, corresponding to water, n-butanol, ethyl acetate and petroleum ether extracts, respectively) of hawthorn. Through metabolomics analysis, a total of 20 significantly metabolites were identified with significant changes in their abundance levels and these metabolites were related to many metabolic pathways such as amino acid metabolism and primary bile acid biosynthesis. The results showed that T3 had the best therapeutic effect of promoting gastrointestinal motility. Other parts showed no obvious therapeutic effect, demonstrating that the effective components of hawthorn may be compounds of medium polarity. T3 might achieve good therapeutic effects owing to the gastrointestinal motility promotion activity, and by rectifying the disturbed metabolic pathways in the gastrointestinal motility disorder model.

Abstract
Gastrointestinal (GI) motility is a key component of digestive health, and it is a complex both rhythmic and arrhythmic process governed by many physiological factors. The ability to accurately track the movements of the GI tissues in vitro over multiple days would provide valuable insights into GI tract physiology. A correlational analysis tracking algorithm was developed and applied to intestinal smooth muscle tissues that were maintained in organotypic culture. Physiologically relevant metrics, such as frequency, amplitude and motility index were independently assayed to quantify smooth muscle contractions. The results were validated by manually detected frequency determined using a standard software package. The algorithm was capable of tracking the changes in contractions of the same tissues over six days. This proof-of-concept study demonstrates the feasibility of long-term tracking of GI motility in organotypic cultures over multiple days. The approach allows study of the effects on GI smooth muscle contractility of direct controlled targeting of the cells and molecules in the GI tunica muscularis.
