Abstract
Background: Chronic urticaria (CU) is a commonly seen skin disorder featured by recurring wheals, with or without angioedema, lasting for at least 6 weeks. Runzao Zhiyang capsule (RZC) has been widely applied to treat patients with CU. This study is aimed at systematically evaluating the efficacy and safety of RZC in treating CU. Materials and Methods: Randomized controlled trials (RCTs) of RZC on treating CU from Chinese and English databases were searched. Data were collected by two independent researchers. The Cochrane Collaboration tool was adopted for evaluating the risk of bias. The meta-analysis was performed with Review Manager 5.3 software. Sensitivity analysis and publication bias assessment were conducted by Stata 14.0 software. Results: Totally 27 studies were included in the analysis, involving 2,703 patients. The pooled results showed that compared with second-generation H1-antihistamines (sgAHs) therapy alone, RZC combined with sgAHs is more effective in improving the total effective rate (RR = 1.32, 95% CI: 1.25 to 1.39, p < 0.00001), the quality of life measured by Dermatology Life Quality Index (DLQI) (MD = -2.63, 95% CI: -3.68 to -1.58, p < 0.00001) and the serum IFN-γ level (SMD = 3.10, 95% CI: 1.58 to 4.62, p < 0.0001), and reducing the recurrence rate (RR = 0.39, 95% CI: 0.27 to 0.55, p < 0.00001), the serum total IgE level (SMD = -2.44, 95% CI: -3.51 to -1.38, p < 0.00001), the serum IL-4 level (SMD = -2.96, 95% CI: -4.10 to -1.83, p < 0.00001), and the incidence of adverse events including dizziness, fatigue, dry mouth, and constipation (RR = 0.53, 95% CI: 0.33 to 0.85, p = 0.009; RR = 0.46, 95% CI: 0.26 to 0.84, p = 0.01; RR = 0.57, 95% CI: 0.34 to 0.95, p = 0.03; RR = 0.24, 95% CI: 0.07 to 0.85, p = 0.03). Conclusion: The current evidence indicates that RZC may be an efficient therapeutic regimen in patients with CU. Nevertheless, owing to the suboptimal quality of the included studies, more large-scale, well-designed RCTs are required to verify the obtained findings.

JOURNAL OF ETHNOPHARMACOLOGY 2023; 308:116217. [PMID: 36758914 DOI: 10.1016/j.jep.2023.116217] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/06/2022] [Revised: 12/28/2022] [Accepted: 01/26/2023] [Indexed: 06/07/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Polygonum multiflorum Radix (PMR) is the dried root tuber of Polygonum multiflorum Thunb., which has been used in the clinic for a variety of pharmacological activities. However, Polygonum multiflorum Radix-induced liver injury (PMR-ILI) has been reported in recent years, which has limited its clinical use to some extent. The occurrence of PMR-ILI is not universal, so finding the different metabolic characteristics between PMR-ILI and Polygonum multiflorum Radix-tolerance group (PMR-T) is very important for the PMR rational clinical application and PMR-ILI early clinical diagnosis. METHODS In this study, 6 clinical plasma samples of PMR-ILI and 13 PMR-T were collected and analyzed by high-resolution liquid chromatography-mass spectrometry. Firstly, the differential metabolites of the two groups were screened by conventional screening methods such as multivariate statistical analysis. Secondly, the characteristic metabolites with greater contribution, correlation with liver injury and high sensitivity were screened by correlation analysis with clinical liver injury indicators, random forest analysis, and receiver operating characteristic curve (ROC). RESULTS After multivariate statistical analysis and screening analysis, 29 differential metabolites were identified. Compared with PMR-T group, the metabolism of glycerol and phospholipid, glutamine and glutamate, phenylalanine, sphingolipid and tryptophan in PMR-ILI group were disturbed. After correlation analysis with liver injury indexes and random forest screening, 8 potential biomarkers closely related to clinical liver injury were obtained. Finally, 3 potential biomarkers with high expression in PMR-ILI, hypoxanthine, LysoPC(P-16:0/0:0) and taurochenodesoxycholic acid, were screened out through the analysis of ROC, which can provide a basis for the early clinical diagnosis. CONCLUSION Based on the analysis of the PMR-ILI and PMR-T plasma samples by LC-MS, three biomarkers of clinical liver injury of Polygonum multiflorum Radix were selected: hypoxanthine, LysoPC(P-16:0/0:0) and taurochenodeoxycholic acid.

Exploration of components and mechanisms of Polygoni Multiflori Radix-induced hepatotoxicity using siRNA -mediated CYP3A4 or UGT1A1 knockdown liver cells. JOURNAL OF ETHNOPHARMACOLOGY 2021; 270:113845. [PMID: 33485974 DOI: 10.1016/j.jep.2021.113845] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/05/2020] [Revised: 01/10/2021] [Accepted: 01/14/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Polygoni Multiflori Radix, the dried root of Polygonum multiflorum Thunb., and its processed products have been used as restoratives for centuries in China. However, the reports of Polygoni Multiflori Radix-induced liver injury (PMR-ILI) have received wide attention in recent years, and the components and mechanism of PMR-ILI are not completely clear yet. Our previous studies found that the PMR-ILI was related to the down-regulation of some drug metabolism enzymes (DME). AIM OF THE STUDY To explore the effect of the inhibition of CYP3A4 or UGT1A1 on PMR-ILI, screen the relevant hepatotoxic components and unveil its mechanism. METHODS RT-qPCR was used to detect the effects of water extract of Polygoni Multiflori Radix (PMR) and its main components on the mRNA expression of CYP3A4 and UGT1A1 in human hepatic parenchyma cell line L02. High-performance liquid chromatography (HPLC) was employed to detect the content of major components in the PMR. And then, the stable CYP3A4 or UGT1A1 knockdown cells were generated using short hairpin RNAs (shRNA) in L02 and HepaRG cells. Hepatotoxic components were identified by cell viability assay when PMR and its four representative components, 2,3,5,4'-tetrahydroxy stilbene glycoside (TSG), emodin (EM), emodin-8-O-β-D-glucoside (EG), and gallic acid (GA), acted on CYP3A4 or UGT1A1 knockdown cell lines. The PMR-ILI mechanism of oxidative stress injury and apoptosis in L02 and HepaRG cells were detected by flow cytometry. Finally, the network toxicology prediction analysis was employed to excavate the targets of its possible toxic components and the influence on the metabolic pathway. RESULTS PMR and EM significantly inhibited the mRNA expression of CYP3A4 and UGT1A1 in L02 cells, while TSG and GA activated the mRNA expression of CYP3A4 and UGT1A1, and EG activated CYP3A4 expression while inhibited UGT1A1 expression. The contents of TSG, EG, EM and GA were 34.93 mg/g, 1.39 mg/g, 0.43 mg/g and 0.44 mg/g, respectively. The CYP3A4 or UGT1A1 knockdown cells were successfully constructed in both L02 and HepaRG cells. Low expression of CYP3A4 or UGT1A1 increased PMR cytotoxicity remarkably. Same as PMR, the toxicity of EM and GA increased in shCYP3A4 and shUGT1A1 cells, which suggested EM and GA may be the main components of hepatotoxicity in PMR. Besides, EM not only inhibited the expression of metabolic enzymes but also reduced the cytotoxicity threshold. EM and GA affected the level of ROS, mitochondrial membrane potential, Ca2+ concentration, and dose-dependent induced hepatocyte apoptosis in L02 and HepaRG cells. The network toxicology analysis showed that PMR-ILI was related to drug metabolism-cytochrome P450, glutathione metabolism, and steroid hormone biosynthesis. CONCLUSION The inhibition of mRNA expression of CYP3A4 or UGT1A1 enhanced hepatotoxicity of PMR. EM and GA, especially EM, may be the main hepatotoxic components in PMR. The mechanism of PMR, EM and GA induced hepatotoxicity was proved to be related to elevated levels of ROS, mitochondrial membrane potential, Ca2+ concentration, and induction of apoptosis in liver cells.

Efficacy and Safety of Runzao Zhiyang Capsule as an Add-On Therapy for Chronic Eczema: A Systematic Review and Meta-Analysis. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:6693268. [PMID: 33815560 PMCID: PMC7990555 DOI: 10.1155/2021/6693268] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/08/2020] [Revised: 03/02/2021] [Accepted: 03/05/2021] [Indexed: 11/17/2022]
Abstract
Background Runzao Zhiyang capsule (RZC), an oral Chinese herbal medicine, has been widely used for chronic eczema in China for many years. This study aims to evaluate the efficacy and safety of RZC as an add-on therapy to conventional treatment for chronic eczema. Methods Randomized controlled trials (RCTs) assessing the efficacy and safety of RZC as an add-on therapy for chronic eczema were retrieved from eight literature databases from their inception to 31 August, 2020, including CNKI, WanFang, VIP, Sinomed, PubMed, Cochrane Library, Web of Science, and Embase. The Cochrane risk of bias tool was used to assess the methodological quality of the included studies. The data were analyzed by RevMan5.3 software. Results A total of 18 RCTs involving 1896 patients with chronic eczema were included. Compared with no oral treatment, RZC was superior on the total efficacy rate (TER) (RR = 1.45, 95% CI: 1.23 to 1.72, P < 0.0001), Eczema Area and Severity Index (EASI) (MD = -0.73, 95% CI: -0.90 to -0.56, P < 0.00001), and Visual Analogue Scale (VAS) for pruritus (MD = -2.76, 95%CI: -4.53 to -0.99, P=0.002). Similar results were also seen in a randomized, placebo-controlled trial. Compared with the antihistamine (AH) group, TER in the RZC combined with AH group was significantly higher (RR = 1.32, 95% CI: 1.21 to 1.43, P < 0.00001), and the EASI score (MD = -0.29, 95% CI: -0.38 to -0.20, P < 0.001), the VAS score (MD = -0.19, 95% CI: -0.23 to -0.15, P < 0.00001), and the level of serum total IgE (MD = -9.83 ng/ml, 95% CI: -11.66 to -8.00 ng/ml, P < 0.00001) decreased more significantly in the RZC combined with AH group. In terms of safety, mild gastrointestinal diseases occurred more frequently in the RZC group, and no serious adverse effect was reported. Conclusions RZC as an add-on therapy to conventional treatment shows good effects on chronic eczema, and there is no severe side effect from short-term use of RZC. However, due to suboptimal quality of the included studies, more large-sample and high-quality RCTs are needed to improve the evidence quality.

Sethi GS, Naura AS. Progressive increase in allergen concentration abrogates immune tolerance in ovalbumin-induced murine model of chronic asthma. Int Immunopharmacol 2018; 60:121-131. [PMID: 29729496 DOI: 10.1016/j.intimp.2018.04.047] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2018] [Revised: 04/27/2018] [Accepted: 04/28/2018] [Indexed: 12/11/2022]
Abstract
Persistent inflammation and remodeling of airways are the major hallmarks of asthma. Though airway inflammation diminishes in ovalbumin (OVA)-based mouse model of chronic asthma owing to immune-tolerance linked with repeated allergen exposure, which limits the application of the disease model. Accordingly, the present study was designed to develop a murine model of chronic asthma which presents persistent airway inflammation coupled with remodeling traits. Herein, OVA-sensitized BALB/c mice were challenged with increasing (modified protocol) or constant concentration (conventional protocol) of the allergen for 6 weeks; 3 times/week. The results, indeed, revealed that mice subjected to modified protocol demonstrate an improved response to the allergen as reflected by the significant increase in inflammatory cells particularly, eosinophils in bronchoalveolar lavage fluid compared to conventional protocol. Moreover, the expression of Th2 cytokines and their responsible transcription factors (GATA-3 and STAT-6) was markedly enhanced in lungs. The increase in inflammation was further accompanied by a marked increase in mucus production, collagen deposition, and the expression of allied factors (Muc5ac, Col1α1, and α-SMA). Interestingly, pre-treatment of dexamethasone, a corticosteroid (0.5 mg/kg b.wt., i.p.), suppressed the allergen-induced airway inflammation and mucus production without altering collagen deposition. Failure of dexamethasone seems to be related to their ineffectiveness to modulate the expression of TGF-β, MMP-9, COL1α1, and α-SMA. Overall, our results strongly suggest that mice underwent modified chronic protocol bears more resemblance with asthmatics as it imitates persistent airway inflammation allied with steroid-refractory remodeling traits; hence, may be useful for the evaluation of new/alternative drugs in steroid-refractory asthmatic conditions.
