[PMID: 38657365 DOI: 10.1016/j.jpba.2024.116163] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2024] [Revised: 04/17/2024] [Accepted: 04/17/2024] [Indexed: 04/26/2024]
Abstract
Psoriasis is a refractory inflammatory skin disorder in which keratinocyte hyperproliferation is a crucial pathogenic factor. Up to now, it is commonly acknowledged that psoriasis has a tight connection with metabolic disorders. Withanolides from Datura metel L. (DML) have been proved to possess anti-inflammatory and anti-proliferative properties in multiple diseases including psoriasis. Withanolide B (WB) is one of the abundant molecular components in DML. However, existing experimental studies regarding the potential effects and mechanisms of WB on psoriasis still remain lacking. Present study aimed to integrate network pharmacology and untargeted metabolomics strategies to investigate the therapeutic effects and mechanisms of WB on metabolic disorders in psoriasis. In our study, we observed that WB might effectively improve the symptoms of psoriasis and alleviate the epidermal hyperplasia in imiquimod (IMQ)-induced psoriasis-like mice. Both network pharmacology and untargeted metabolomics results suggested that arachidonic acid metabolism and arginine and proline metabolism pathways were linked to the treatment of psoriasis with WB. Meanwhile, we also found that WB may affect the expression of regulated enzymes 5-lipoxygenase (5-LOX), 12-LOX, ornithine decarboxylase 1 (ODC1) and arginase 1 (ARG1) in the arachidonic acid metabolism and arginine and proline metabolism pathways. In summary, this paper showed the potential metabolic mechanisms of WB against psoriasis and suggested that WB would have greater potential in psoriasis treatment.

Triterpenoids from the leaves of Eleutherococcus sessiliflorus, and their antiproliferative activities in TNF-α induced HFLS-RA cells. PHYTOCHEMISTRY 2024; 223:114133. [PMID: 38710375 DOI: 10.1016/j.phytochem.2024.114133] [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: 10/21/2023] [Revised: 04/30/2024] [Accepted: 05/02/2024] [Indexed: 05/08/2024]
Abstract
Five undescribed elesesterpenes L-U, along with nine known 3,4-seco-lupane-type triterpenoids were isolated from the leaves of Eleutherococcus sessiliflorus (Rupr. & Maxim.) S. Y. Hu. Elesesterpene L-S, and U were lupane-type triterpenoids, whereas elesesterpene T was an oleanane-type triterpenoid, probably artifact, as suggested by LC-MS analysis. Out of the nine known compounds, five were initially identified in E. sessiliflorus. Moreover, their structures were definitively determined using spectroscopic analyses, and the absolute configurations of elesesterpenes L-M and sachunogenin 3-O-glucoside were clarified using X-ray crystallographic techniques. The absolute configuration of elesesterpene T was determined by measuring and calculating its ECD. In addition, all compounds were tested to examine their ability to inhibit the proliferation of HFLS-RA cells induced by TNF-α in vitro. Elesesterpene M, chiisanogenin, chiisanoside, and 3-methylisochiisanoside significantly inhibited HFLS-RA proliferation.

Elucidating the hepatoprotective mechanisms of cholic acid against CCl 4-Induced acute liver injury: A transcriptomic and metabolomic study. JOURNAL OF ETHNOPHARMACOLOGY 2024; 328:118052. [PMID: 38518967 DOI: 10.1016/j.jep.2024.118052] [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: 12/07/2023] [Revised: 02/20/2024] [Accepted: 03/12/2024] [Indexed: 03/24/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cholic acid (CA) is one of the main active ingredients in Calculus Bovis, a traditional Chinese medicine, which helps to regulate the heart and liver meridians, clearing the heart, opening the mouth, cooling the liver and calming the wind. However, the molecular mechanism of its liver protective effect is still unclear. AIM OF THE STUDY Growing attention has been directed towards traditional Chinese medicine (TCM), particularly Calculus Bovis, as a potential solution for liver protection. Despite this interest, a comprehensive understanding of its hepatoprotective mechanisms remains lacking. This research seeks to explore the potential protective properties of cholic acid (CA) against CCl4-induced acute liver injury (ALI) in mice, while also examining the mechanisms involved. MATERIALS AND METHODS In the experiment, a mouse model was employed to ALI using CCl4, and the potential therapeutic effects of orally administered CA at varying doses (15, 30, and 60 mg/kg) were assessed. The study employed a multi-faceted approach, integrating liver transcriptomics with serum metabolomics, and conducting thorough analyses of serum biochemical markers and liver histopathological sections. RESULTS Oral CA administration markedly reduced the organ indices of the liver, spleen, and thymus in comparison with the model group. It also elevated the expression of superoxide dismutase (SOD) in serum while diminishing the concentrations of ALT, AST, MDA, IL-6, and TNF-α. Moreover, CA ameliorated the pathological damage induced by CCl4. Integrated metabolomic and transcriptomic analyses indicated that the hepatoprotective action of CA on ALI is mediated through the modulation of lipid metabolic pathways-specifically, metabolisms of glycerophospholipid, arachidonic acid, as well as linoleic acid-and by altering the expression of genes such as Ptgr1, PLpp1, Tbxas1, and Cyp2c37. CONCLUSIONS The current investigation offers insights into the hepatoprotective mechanisms by which CA mitigates ALI caused by CCl4 exposure, thus supporting the further evaluation and development of CA-based therapeutics for ALI.

Effects of Viscum coloratum (Kom.) Nakai on collagen-induced rheumatoid arthritis. JOURNAL OF ETHNOPHARMACOLOGY 2024; 327:118026. [PMID: 38490288 DOI: 10.1016/j.jep.2024.118026] [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: 01/01/2024] [Revised: 02/18/2024] [Accepted: 03/06/2024] [Indexed: 03/17/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Viscum coloratum (Kom.) Nakai has been traditionally used in China for nearly a thousand years to treat rheumatic diseases. However, its efficacy and mechanisms in treating rheumatoid arthritis (RA) have not been demonstrated. AIM OF THE STUDY To investigate the anti-arthritic effects and molecular mechanisms of Viscum coloratum (Kom.) Nakai on collagen-induced arthritic mice through network pharmacology technology and experimental validation. MATERIALS AND METHODS First, the main ingredients of the extract of Viscum coloratum (Kom.) Nakai (EVC) were identified through chemical composition characterization using Ultra Performance Liquid Chromatography Tandem Mass Spectrometry (UPLC-MS). Then, the collagen-induced arthritis (CIA) model was established in DBA/1 J mice and the ameliorative effects of EVC on the progression of CIA mice were evaluated by oral treatment with different doses of the EVC for 28 days. After that, cytokine antibody microarray assay was used to detect the levels of multiple inflammation-related cytokines and chemokines in each group, and performed Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genome (KEGG) enrichment analysis. Subsequently, the potential target for the effective chemical components of EVC in treating RA was identified using various databases. Additionally, a drug-disease target protein-protein interaction network (PPI) was conducted using Cytoscape for visualization and clustering, while GO and KEGG enrichment analyses were performed with the Metascape database. Finally, identified phenotypes and targets by network pharmacology analysis were experimentally validated in vivo. RESULTS Treatment with EVC significantly suppressed the severity of CIA with a dramatic reduction of paw swelling, arthritis index, levels of IgGs (IgG, IgG1, IgG2a, and IgG2b), multi-inflammation-related cytokines and chemokines on the progression of CIA. Histopathological examinations showed EVC could markedly inhibit inflammatory cell infiltration, tartrate-resistant acid phosphatase (TRAP) activity of osteoclast, and bone destruction. Furthermore, GO and KEGG enrichment analyses revealed that EVC could ameliorate RA by inhibiting osteoclast differentiation and regulating multiple signaling pathways including Osteoclast differentiation, IL-17, and TNF. PPI network analysis demonstrated that AKT1, MMP9, MAPK3, and other genes were highly related to EVC in treating RA. Finally, we proved that EVC could inhibit the expression of NFTAc1, MMP9, Cathepsin K, and AKT which were closely related to osteoclast activity. CONCLUSIONS EVC could treat RA through multiple components, multiple targets, and multiple pathways. The present study demonstrated the therapeutic efficacy of EVC and its molecular mechanisms in treating RA, indicating that it would be a potent candidate as a novel botanical drug for further investigation.

Abstract
Schisandra chinensis (SC), a plant of the Magnoliaceae family, commonly known as "North Schisandra chinensis", has been listed as a top-grade Chinese medicine in the Shennong Materia Medica Classic for its high medicinal value since ancient times. Polysaccharides from S. chinensis fruits (SCPs) are an active component in SC, which have various biological activity, including immune regulation, anti-tumor, antioxidant, liver protective, anti-inflammatory and hypoglycemic activity. Research has shown that the extraction methods of SCPs include hot water extraction, water extraction and alcohol precipitation, ultrasonic-assisted, microwave-assisted and so on. Different extraction methods can affect the yield and purity of polysaccharides, and to improve the extraction yield of SCPs, two or more extraction methods can be combined. SCPs are mainly composed of glucose, mannose, rhamnose, galactose, galacturonic acid and arabinose. This article aims to provide a systematic review of the research progress in the extraction and separation methods, structural characterization, and biological activity of SCPs both domestically and internationally in recent years. This deeply explores the pharmacological activity and action mechanism of SCPs, and provides a certain point of reference for the research and clinical application of SC.

Abstract
Schisandra chinensis (Turcz.) Baill (SC) is a traditional sedative in China, with wide applications for treating various neurological disorders. Its polysaccharide component has been gaining increased attention for its potential in nerve protection. While raw SC is the primary focus of current research, its processed products are primarily utilized as clinical medicines. Notably, limited research exists on the mechanisms underlying the effects of wine-processed Schisandra chinensis polysaccharide (WSCP) in Alzheimer's Disease (AD). Therefore, this study seeks to assess the therapeutic impact of WSCP on AD mice and investigate the underlying mechanisms through biochemical and metabolomics analyses. The results demonstrate that WSCP exerts significant therapeutic effects on AD mice by enhancing learning and memory abilities, mitigating hippocampal neuronal damage, reducing abnormal amyloid-beta (Aβ) deposition, and attenuating hyperphosphorylation of Tau. Biochemical analysis revealed that WSCP can increase SOD content and decrease MDA, IL-6, and TNF-α content in AD mice. Furthermore, serum metabolomic results showed that WSCP intervention can reverse metabolic disorders in AD mice. 43 endogenous metabolites were identified as potential biomarkers for WSCP treatment of AD, and the major metabolic pathways were Ala, Glu and Asp metabolism, TCA cycle. Overall, these findings will provide a basis for further development of WSCP.

Protopine ameliorates OVA-induced asthma through modulatingTLR4/MyD88/NF-κB pathway and NLRP3 inflammasome-mediated pyroptosis. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 126:155410. [PMID: 38367422 DOI: 10.1016/j.phymed.2024.155410] [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: 10/29/2023] [Revised: 01/05/2024] [Accepted: 02/01/2024] [Indexed: 02/19/2024]
Abstract
BACKGROUND Chronic airway inflammation and hyperresponsiveness are characteristics of asthma. The isoquinoline alkaloid protopine (PRO) has been shown to exert anti-inflammatory effects, but its mechanism of action in asthma is not known. PURPOSE Investigate the protective properties of PRO upon asthma and elucidate its mechanism. STUDY DESIGN AND METHODS The effects of PRO in asthma treatment were assessed by histology, biochemical analysis, and real-time reverse transcription-quantitative polymerase chain reaction. Then, we integrated molecular docking, western blotting, cellular experiments, immunohistochemistry, immunofluorescence analysis, flow cytometry, and metabolomics analysis to reveal its mechanism. RESULTS In vivo, PRO therapy reduced the number of inflammatory cells (eosinophils, leukocytes, monocytes) in bronchoalveolar lavage fluid (BALF), ameliorated pathologic alterations in lung tissues, and inhibited secretion of IgG and histamine. Molecular docking showed that PRO could dock with the proteins of TLR4, MyD88, TRAF6, TAK1, IKKα, and TNF-α. Western blotting displayed that PRO inhibited the TLR4/NF-κB signaling pathway. PRO regulated expression of the pyroptosis-related proteins NLR family pyrin domain containing 3 (NLRP3) inflammasome, gasdermin D, caspase-1, and drove caspase-1 inactivation to affect inflammatory responses by inhibiting the NLRP3 inflammasome. In vitro, 24 h after treatment with PRO, cell activity, as well as levels of reactive oxygen species (ROS) and interleukin (IL)-1β and IL-18, decreased significantly. Immunofluorescence staining showed that PRO decreased expression of TLR4 and MyD88 in vitro. PRO decreased nuclear translocation of NF-κB p65. Twenty-one potential biomarkers in serum were identified using metabolomics analysis, and they predominantly controlled the metabolism of phenylalanine, tryptophan, glucose, and sphingolipids. CONCLUSION PRO reduced OVA-induced asthma. The underlying mechanism was associated with the TLR4/MyD88/NF-κB pathway and NLRP3 inflammasome-mediated pyroptosis.

Abstract
The ongoing coronavirus infectious disease (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) still urgently requires effective treatments. The 3C-like (3CL) protease of SARS-CoV-2 is a highly conserved cysteine protease that plays an important role in the viral life cycle and host inflammation, providing an ideal target for developing broad-spectrum antiviral drugs. Herein, we describe the discovery of a large number of herbs mainly produced in Heilongjiang Province, China, that exhibited different inhibitory activities against SARS-CoV-2 3CL protease. We confirmed that Syringa reticulata, which is used for clinical treatment of chronic bronchitis and asthma, is a specific and potent inhibitor of 3CL protease. A 70 % ethanol extract of S. reticulata dose-dependently inhibited the cleavage activity of 3CL protease in a fluorescence resonance energy transfer assay with an IC50 value of 0.0018 mg/mL, but had minimal effect in pseudovirus-based cell entry and luciferase-based RNA-dependent RNA polymerase assays. These results suggest that S. reticulata will be a potential leading candidate for COVID-19 treatment.

Effects and mechanisms of frehmaglutin D and rehmaionoside C improve LPS-induced acute kidney injury through the estrogen receptor-mediated TLR4 pathway in vivo and in vitro. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 123:155218. [PMID: 37980806 DOI: 10.1016/j.phymed.2023.155218] [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: 07/27/2023] [Revised: 10/30/2023] [Accepted: 11/12/2023] [Indexed: 11/21/2023]
Abstract
BACKGROUND Sepsis-induced acute kidney injury (S-AKI) is an inflammatory disease with sex differences and there has no effective drugs to cure it. Frehmaglutin D (Fre D) and rehmaionoside C (Reh C) are two violetone compounds with estrogenic activity isolated from Rehmannia glutinosa. However, whether these two drugs exert protective effects on S-AKI through their estrogen-like activity are unclear. PURPOSE This study aimed to explore the effects and mechanisms of Fre D and Reh C on lipopolysaccharide (LPS)-induced S-AKI through the estrogen receptor pathway in vivo and in vitro and to explore the interaction between ER and TLR4 for the first time. METHODS The LPS-induced female BALB/c mice S-AKI mouse model was established by adding the estrogen receptor antagonist ICI182,780. Renal function, inflammation, oxidative stress, apoptosis, immune cells, and expression of key proteins of the ER-TLR4-IL-1β pathway were tested. The affinity of Fre D and Reh C for the ER was investigated by molecular docking. Then, an in vitro S-AKI model was established, and ERα/ERβ antagonists (MPP/PHTPP) were added and combined with gene overexpression techniques. The interaction between ER and TLR4 was further explored by Co-IP, GST pull-down and SPR techniques. RESULTS Fre D and Reh C ameliorated LPS-induced renal damage, inflammation in mice, regulated the immune cells, decreased ROS levels, increased ERα and ERβ protein expression, and decreased TLR4, caspase 11 and IL-1β protein expression. These effects were blocked by ICI182,780. Molecular docking results showed that Fre D and Reh C bound ERα and ERβ with similar potency. The results of in vitro suggested that Fre D and Reh C reduced the levels of inflammation, ROS and apoptosis, TLR4, caspase 11, and IL-1β protein expression and increased ERα/ERβ protein expression in cells. All of these effects were reversed by the addition of MPP/PHTPP and further enhanced after ERα/ERβ gene overexpression with no significant difference in effects. Moreover, there was an indirect or direct interaction between ER and TLR4, and the binding of ERα and ERβ to TLR4 was concentration dependent. CONCLUSION Fre D and Reh C may improve S-AKI through the ER-TLR4-IL-1β pathway and may act on both ERα and ERβ receptors. Moreover, ERα and ERβ may interact directly or indirectly with TLR4, which was studied for the first time.

Abstract
C. officinalis Kuan is the dry root of Cyathula officinalis Kuan. Clinically, it is used for fall and flutter injury, rheumatism and arthralgia. Phytoecdysteroids have significant anti-inflammatory effects, and the phytoecdysteroids present in C. officinalis Kuan exhibit potential for treating rheumatoid arthritis.This study first developed a selective, accurate and efficient LC-MS/MS method for 12-day pharmacokinetic studies regarding the simultaneous determination of cyasterone, 25-epi-28-epi-cyasterone, precyasterone and capitasterone from C. officinalis Kuan phytoecdysteroids extract in normal and adjuvant arthritis rats.An Agilent Eclipse Plus C18 RRHD column (1.8 µm, 50mm × 2.1 mm) with a gradient mobile phase consisting of water (A) and acetonitrile (B) was used for analysis. The mass analysis was performed in an Agilent 6430 QQQ-MS mass spectrometer with positive mode multiple reaction monitoring (MRM).The results indicated that the AUC0-t and AUC0-∞ values of the four phytoecdysteroids in adjuvant arthritis rats were different from those in normal rats on the first day, which could provide a helpful reference for pharmacological and toxicological studies, as well as clinical applications of C. officinalis Kuan in the treatment of rheumatoid arthritis.

Abstract
Bile acids are the main component of animal bile and are directly involved in the metabolic process of lipids in vivo. Taurochenodeoxycholic acid (TCDCA) is the primary biologically active substance in bile acids and has biological functions such as antioxidant, antipyretic, anti-inflammatory, and analgesic activities and improves immunity. In the present study, we assessed the impact of TCDCA on hyperlipidemia development in mouse models. Mice were fed a high-fat diet (HFD) to induce hyperlipidemia and orally administered different doses of TCDCA orally for 30 days. Then, indicators such as triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) in mice were detected. Using HE and ORO staining techniques, the morphology of the mice's liver tissue was detected. Based on metabolomic and lipidomic analyses, we determined the mechanism of TCDCA in treating hyperlipidemia. The results showed that TCDCA had a significant ameliorating effect on dietary hyperlipidemia. In addition, it exerted therapeutic effects through glycerophospholipid metabolism.

Abstract
Hyperlipidaemia, which is characterized by an excess of lipids or fats in the bloodstream, is a high-risk factor and critical indicator of many metabolic diseases. This study used 16 S rRNA gene sequencing and metabolomics to determine that stachyose (ST) has a therapeutic effect and is a mechanism of hyperlipidaemia. These results show that ST significantly attenuated high-fat diet-induced weight gain and fat deposition while also adjusting the gut microbial composition. Untargeted serum metabolomics identified 12 biomarkers, which suggests that ST may function by regulating metabolic pathways. These results highlight the potential of ST in treating hyperlipidaemia and provides directions for future research including an in-depth investigation of the bioactive components, dosage, and treatment strategies of ST.

Serum, spleen metabolomics and gut microbiota reveals effect of catalpol on blood deficiency syndrome caused by cyclophosphamide and acetylphenylhydrazine. Front Immunol 2023; 14:1280049. [PMID: 38022670 PMCID: PMC10655121 DOI: 10.3389/fimmu.2023.1280049] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2023] [Accepted: 10/20/2023] [Indexed: 12/01/2023] Open
Abstract
Catalpol (CA), extracted from Rehmannia Radix, holds extensive promise as a natural medicinal compound. This study employed 16S rRNA gene sequencing and combined serum and spleen metabolomics to profoundly investigate the therapeutic effects of CA on blood deficiency syndrome (BDS) and the underlying mechanisms. Notably, CA exhibited effectiveness against BDS induced by cyclophosphamide (CP) and acetylphenylhydrazine (APH) in rats-CA substantially elevated levels of crucial indicators such as erythropoietin (EPO), granulocyte colony-stimulating factor (G-CSF), tumor necrosis factor-alpha (TNF-a), and interleukin-6 (IL-6). Additionally, CA could alleviate peripheral blood cytopenia. Furthermore, the analysis of 16S rRNA revealed that CA had the potential to reverse the Firmicutes/Bacteroidetes (F/B) ratio associated with BDS. Through comprehensive serum and spleen metabolomic profiling, we successfully identified 22 significant biomarkers in the serum and 23 in the spleen, respectively. Enrichment analysis underscored Glycerophospholipid metabolism and Sphingolipid metabolism as potential pathways through which CA exerts its therapeutic effects on BDS.

Abstract
A selective and sensitive ultra-high-performance liquid chromatography-tandem mass spectrometry method was developed and validated for the determination of three triterpenoid saponins isolated from Astragalus membranaceus leaf extract. In this article, a method for simultaneous determination of Huangqiyenin A, Huangqiyenin E, and Huangqiyenin K was established for the first time. The method was successfully applied to the pharmacokinetic study of Astragalus membranaceus leaf extract after oral administration. Liquid-liquid extraction was applied to plasma sample preparation. Multiple reaction monitoring mode with an electrospray ion source in positive electrospray ionization was chosen to quantify the analytes. Chromatographic separation was performed on a Waters HSS T3 column, using gradient elution with a mobile phase composed of acetonitrile and 5 mM ammonium acetate/water. The pharmacokinetic results showed that all three compounds had the characteristics of rapid absorption-slow metabolism trend. The time of maximum plasma concentration of Huangqiyenin A is higher than Huangqiyenin E and Huangqiyenin K. And the maximum plasma concentration of Huangqiyenin A is higher as well. The pharmacokinetic results revealed the pharmacokinetic characteristics of the three analytes in rat plasma, which could provide a helpful reference for the further study of Astragalus membranaceus leaf extract.

Abstract
PURPOSE/OBJECTIVE(S) There have been numerous studies to date on the treatment of tumors by saturated fatty acids. But the role that ferroptosis plays in this is not clear. Palmitic acid (PA) is a common saturated fatty acid with huge application prospects for inducing tumor cell ferroptosis. MATERIALS/METHODS In vivo and in vitro experiments were performed to verify changes in cell proliferation, apoptosis and ferroptosis after PA treatment of colon cancer cells. Changes in ROS, lipid peroxidation, ferric ions, calcium ions, endoplasmic reticulum (ER) stress, endocytosis recycling trafficking of transferrin after PA treatment of colon cancer cells were detected. Further using necrosis inhibitor (Necrostatin-1), apoptosis inhibitor (Z-VAD-FMK), autophagy inhibitor (CQ), iron death inhibitor (Fer-1), calcium / ferric ion chelator (BAPTA-AM / DFP), iron supplement (FAC), calcium ion agonist (thapsigargin) for positive and negative verification. The association of CD36 expression and patient prognosis in colon cancer patients was subsequently evaluated by bioinformatics analysis. Detect the difference of CD36 expression in different colon cancer cells induced by PA, and further knock down or over express CD36 to explore the change of sensitivity to PA induced ferroptosis. RESULTS PA inhibited colon cancer cell viability in vitro and in vivo, in conjunction with an accumulation of ROS and lipid peroxidation. The ferroptosis inhibitor Ferrostatin-1 but not Z-VAD-FMK, Necrostatin-1, or CQ rescued the cell death induced by PA. Subsequently, we verified that PA-induced ferroptosis through excess iron as cell death was inhibited by iron chelator deferiprone (DFP) but exacerbated by a supplement of ferric ammonium citrate (FAC). Mechanistically, PA leads to endoplasmic reticulum calcium release by inducing ER stress, and the increase of cytosolic calcium level positively regulates the endocytosis recycling transport of transferrin to promote the increase of intracellular iron content. Furthermore, we observed that cells with high expression of CD36 were more vulnerable to PA-induced ferroptosis. Knocking down the expression of CD36 can inhibit the sensitivity of colon cancer cells to PA induced ferroptosis, and vice versa. CONCLUSION In general, we report for the first time that PA can selectively induce ferroptosis in colon cancer cells with high expression of CD36 by activating ER stress/ER calcium release/transferrin-dependent ferroptosis. This provides a new strategy and basis for the precise treatment of tumors.

Abstract
PURPOSE/OBJECTIVE(S) Although lipids have been assessed for their possible roles in cancer survival prediction, studies on the association between serum lipids levels and the prognosis of non-small cell lung cancer (NSCLC) patients are limited. This study aimed to evaluate whether serum lipids are associated with outcomes in patients with NSCLC treated with radiotherapy. MATERIALS/METHODS We conducted a multicenter prospective study on patients diagnosed with NSCLC between January 2018 and February 2021. Participants received thoracic radiotherapy of 60ཞ80 Gy to the primary lung tumor and positive lymph node metastases. We measured patients' serum lipids levels (serum triglyceride, TGs; total cholesterol, TC, high density lipoprotein cholesterol, HDL-C; low density lipoprotein cholesterol, LDL-C) before radiotherapy. The association between serum lipids levels and overall survival (OS) was evaluated using hazard ratios. We sought to determine a threshold point using optimal stratification. Survival analysis was performed using Kaplan-Meier curves. RESULTS Of the 300 participants diagnosed with NSCLC treated with radiotherapy, 165 (55.0%) were men. Median follow-up time was 24.4 months (range 1.0- 101.9 months). Using univariate and multivariate Cox proportional hazard analysis, among those serum lipids, only serum TG was shown to be independent prognostic factors for OS (hazard ratio: 1.203, 95% confidence interval: 1.038 - 1.393, p = 0.014). The cut-off for TG associated with OS was 2.04 mmol/L. Based on the TG cut-off value, 55 NSCLC patients were categorized into the high TG group (>2.04 mmol/L) and 245 in the low TG group (<2.04 mmol/L). The NSCLC patients in the low TG group exhibited higher OS than the high group (median OS, not reach vs 41.4 months, p = 0.025). CONCLUSION TG levels were found to be a significant negative prognostic biomarker for OS in NSCLC patients treated with radiotherapy.

Abstract
Cinobufagin (CBF) is a bufadienolide, which is a major active ingredient of toad venom. In recent years, CBF has attracted increasing attention due to its highly potent and multiple pharmacological activities. To better understand the status of research on CBF, we collated recent studies on CBF to provide a valuable reference for clinical researchers and practitioners. According to reports, CBF exhibits extensive pharmacological properties, including antitumor, analgesic, cardioprotection, immunomodulatory, antifibrotic, antiviral, and antiprotozoal effects. Studies on the pharmacological activity of CBF have mainly focused on its anticancer activity. It has been demonstrated that CBF has a therapeutic effect on liver cancer, osteosarcoma, melanoma, colorectal cancer, acute promyelocytic leukemia, nasopharyngeal carcinoma, multiple myeloma, gastric cancer, and breast cancer. However, the direct molecular targets of CBF are currently unknown. In addition, there are few reports on toxicological and pharmacokinetic of CBF. Subsequent studies focusing on these aspects will help promote the development and application of CBF in clinical practice.

Abstract
Bear bile powder is an essential, traditional and valuable Chinese herbal medicine that clears heat, calms the liver, and improves eyesight. Early studies have shown that bear bile powder has lipid-lowering activity, but due to the scarcity of natural bear bile powder resources, it has yet to be used on a large scale. Researchers have found that tauroursodeoxycholic acid (TUDCA) is the primary characteristic bioactive substance of bear bile powder. This study aimed to investigate the therapeutic effect of TUDCA on high-fat diet (HFD)-induced hyperlipidemia. A hyperlipidemia model was established by feeding mice high-fat chow, following the intervention of different concentrations of TUDCA (25/50/100 mg/kg) orally, the hallmark biochemical indexes (total cholesterol (TC), total triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C)), histopathological examination (hematoxylin-eosin (HE) staining and oil red O (ORO) staining), and metabolomic analysis of serum and liver. The results showed that TUDCA could downregulate total TC, TG, LDL-C, upregulate HDL-C, reduce fat deposition in hepatocytes, reverse hepatocyte steatosis, and exhibit prominent lipid-lowering activity. In addition, it may play a therapeutic role by regulating glycerophospholipid metabolism.

Abstract
In this study, we developed an ultra-performance liquid chromatography-electrospray tandem quadrupole mass spectrometry (UHPLC-ESI-MS/MS) method to simultaneously determine Picroside-I, Picroside-II, Picroside-III, minecoside, and sweroside in rat plasma. The chromatographic column was an ACQUITY UHPLC® BEH Amide Column (2.1 × 100 mm, 1.7 µm; Waters, MA, USA), column temperature 40 °C. The mobile phase was 0.1% formic acid aqueous solution-0.1% formic acid acetonitrile solution. The flow rate was 0.4 mL/min. Multiple reaction monitoring (MRM) and negative ion modes were adopted. The results showed that the calibration curves of five compounds in plasma showed good linearity (r > 0.9911) over the studied dose range. The lower limits of quantification (LLOQ) for Picroside-I, Picroside-II, Picroside-III, minecoside, and sweroside were 6.876, 5.193, 5.040, 1.260, and 4.527 ng/mL, respectively. The intra-day and inter-day precision were <15%. The matrix effects ranged from 95.77 to 101.9%. The Tmax were 1.1 ± 0.2, 1.1 ± 0.1, 0.8 ± 0.1, 1.0 ± 0.2, and 2.1 ± 0.1 h. This study will be useful in understanding the behavior of drugs in the body and the body's effect on drugs. It also offers theoretical underpinnings and highlights the importance of clinical applications and creating novel drugs.

Abstract
ETHNOPHARMACOLOGY RELEVANCE Duhuo Jisheng decoction is a traditional Chinese formula that has been widely used in clinical practice to treat osteoarthritis, which has the effects of removing invaded cold and dampness, relieving joint pain. However, it is difficult to determine the effective substances and mechanisms due to assorted herbs and components, and further research is needed. AIM OF THE STUDY This study was designed to explore and verify the mechanism and targets of DHJSD in the treatment of OA via network analysis and experiments. METHOD In this study, the active ingredients of DHJSD were qualitatively analyzed by UPLC-QDA. Network analysis was used to identify common targets and pathways. Next, we explored the therapeutic mechanism of DHJSD through a rat model of knee osteoarthritis. HE staining was used to judge the establishment of the animal model. ELISA and Western blotting were used to verify the expression of key pathway proteins. CONCLUSION In this study, seventeen chemical constituents in DHJSD were identified. According to the network analysis, we obtained the potential associated pathways of action. Then, molecular docking and SPR experiments showed that the sixteen identified components had high binding energies to IL-6. HE staining showed that the high-dose group of DHJSD had an obvious therapeutic effect on model rats. Compared with the model group, the levels of IL-1β, TNF-α, IL-6, MMP3, MMP13, ADAMTS4 and ADAMTS5 in serum and the expression of STAT3 and p-STAT3 protein in administration groups were significantly decreased. This result indicated that the IL-6/STAT3 signaling pathway was one of the important pathways regulated by DHJSD to improve OA.

Abstract
Phenylpropionamides in the seed of Cannabis sativa L. (PHS) have a protective effect on neuroinflammation and antioxidant activity. In this study, the UHPLC-Orbitrap-fusion-TMS-based metabolomics approach was used to analyze the serum samples and identify potential biomarkers in Streptozotocin (STZ) induced Alzheimer's disease (AD) rats. The results revealed that ptimary bile acid biosynthesis and taurine and hypotaurine metabolism were significantly correlated with STZ-induced AD rats. In addition, the key enzymes in these two pathways were verified at the protein level. The levels of cysteine dioxygenase type I (CDO1), cysteine sulfinic acid decarboxylase (CSAD), cysteamine (2-aminoethanethiol) dioxygenase (ADO), 7α-hydroxylase (CYP7A1), and sterol 12α-hydroxylase (CYP8B1) were the key enzymes affecting the two pathways in AD rats compared with the control group (CON). Furthermore, after a high-dose group of phenylpropionamides in the seed of Cannabis sativa L. (PHS-H) was administrated, the levels of CDO1, CSAD, CYP7A1, and CYP8B1 were all callback. These findings demonstrate for the first time that the anti-AD effect of PHS is associated with the regulation of primary bile acid biosynthesis and taurine and hypotaurine metabolism in STZ-induced AD rats.

Abstract
The present work reported the extraction, purification, characterization of a polysaccharide from roots of Codonopsis pilosula (CPP-A-1) and its effect on liver fibrosis. The findings exhibited that the molecular weight of CPP-A-1 was 9424 Da, and monosaccharide composition were glucose and fructose and minor contents of arabinose. Structural characterization of CPP-A-1 has a backbone consisting of→(2-β-D-Fruf-1)n→ (n ≈ 46-47). Treatment with CPP-A-1 inhibited the proliferation of transforming growth factor-beta 1 (TGF-β)-activated human hepatic stellate cell line (LX-2), and induced cell apoptosis. We used carbon tetrachloride (CCl4) to construct mice model of liver fibrosis and subsequently administered CPP-A-1 treatment. The results showed that CPP-A-1 alleviated CCl4-induced liver fibrosis as demonstrated by reversing liver histological changes, decreased serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) contents, collagen deposition, and downregulated fibrosis-related collagen I and α-smooth muscle actin (α-SMA), and inhibited the generation of excessive extracellular matrix (ECM) components by restoring the balance between matrix metalloproteinases (MMPs) and its inhibitor (TIMPs). Moreover, CPP-A-1 improved anti-oxidation effects detected by promoting liver superoxide dismutase (SOD), glutathione (GSH) and Mn-SOD levels, and inhibition of liver malondialdehyde (MDA) and iNOS levels. CPP-A-1 also ameliorated the inflammatory factor (tumor necrosis factor-alpha (TNF-α) and interleukin (IL)-6), and expression of inflammatory factor genes (TNF-α, IL-11 mRNA). In addition, our results showed that CPP-A-1 inhibited Toll-like receptor 4 (TLR4)/nuclear factor kappa-B (NF-κB) and transforming growth factor-β1 (TGF-β1)/drosophila mothers against decapentaplegic 3 (Smad3) signaling pathways. Furthermore, In vitro tests of LX-2 cells demonstrated that CPP-A-1 not only inhibited α-SMA expression with lipopolysaccharide (LPS) or TGF-β1 stimulation, but also inhibited TLR4/NF-κB and TGF-β1/Smad3 signaling, similar to corresponding small-molecule inhibitors. Therefore, CPP-A-1 might exert suppressive effects against liver fibrosis by regulating TLR4/NF-κB and TGF-β1/Smad3 signaling, our findings support a possible application of CPP-A-1 for the treatment of liver fibrosis.

Abstract
Cancer poses a serious threat to human health, and the search for safe and effective drugs for its treatment has aroused interest and become a long-term goal. Traditional Chinese herbal medicine (TCM), an ancient science with unique anti-cancer advantages, has achieved outstanding results in long-term clinical practice. Accumulating evidence shows that saponins are key bioactive components in TCM and have great research and development applications for their significant role in the treatment of cancer. Saponins are a class of glycosides comprising nonpolar triterpenes or sterols attached to hydrophilic oligosaccharide groups that exert antitumor effects by targeting the NF-κB, PI3Ks-Akt-mTOR, MAPK, Wnt-β-catenin, JAK-STAT3, APMK, p53, and EGFR signaling pathways. Presently, few advances have been made in physiological and pathological studies on the effect of saponins on signal transduction pathways involved in cancer treatment. This paper reviews the phytochemistry and extraction methods of saponins of TCM and their effects on signal transduction pathways in cancer. It aims to provide theoretical support for in-depth studies on the anticancer effects of saponins.

Abstract
The bulbs of Allium sativum known as garlic are widely used as food or seasoning. In China they have been used as a traditional Chinese medicine (TCM) since ancient times for the treatment of scabies, tuberculosis, pertussis, diarrhea and dysentery. A. sativum has reportedly shown platelet aggregation inhibition and has been used in the treatment of cardiovascular diseases. However, there are only few studies focussing on the aerial parts, which are normally discarded during harvest. In this study, two new ionone glycosides, dasuanxinosides D and E (1, 2: ), are isolated from the aerial parts together with 13 known compounds including alkanes derivatives and alkyl glycosides (3 - 15: ), which are reported for the first time from this plant. Their structures are identified by extensive NMR and HRMS analyses. The isolated compounds are evaluated for their inhibitory effect on adenosine diphosphate (ADP)-induced platelet aggregation in vitro.

The management and metabolic characterization: hyperthyroidism and hypothyroidism. Neuropeptides 2023; 97:102308. [PMID: 36455479 DOI: 10.1016/j.npep.2022.102308] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/19/2022] [Revised: 10/21/2022] [Accepted: 11/08/2022] [Indexed: 11/13/2022]
Abstract
Hyperthyroidism and hypothyroidism are common diseases resulting from thyroid dysfunction, and are simple to diagnose and treat. The traditional treatment for hypothyroidism is thyroid hormone replacement therapy. The traditional treatments for hyperthyroidism include antithyroid drug, iodine radiotherapy, and surgery. Thyroid disease can be fatal in severe cases if untreated. Current statistical reference ranges used for diagnosis based on relevant biochemical parameters have been debated, and insufficient treatment can result in long-term thyroid hormone deficiency, which is associated with increased risk of cardiovascular disease and persistent symptoms. In contrast, overtreatment can result in heart disease and osteoporosis, particularly in older people and pregnant women. Therefore, under- or over-treatment should be avoided and treatment regimens should be monitored closely. A significant proportion of patients who achieve biochemical treatment goals still complain of significant symptoms. Systematic literature review was performed through the Embase (Elsevier), PubMed and Web of Science databases, and studies summarized evidence regarding treatment and management of hypothyroidism and hyperthyroidism, and reviewed clinical practice guidelines. We also reviewed the latest research on the metabolic mechanisms of hyperthyroidism and hypothyroidism, which contributed to understanding of thyroid diseases in the clinic. A reliable algorithm is needed to management, assessment, and treatment patients with hyperthyroidism and hypothyroidism, which can not only improve management efficiency, but also providing a broad application. In addition, the thyroid disorder showed a lipid metabolism tissue specificity in the Ventromedial Hypothalamus, and effect oxidative stress and energy metabolism of whole body. This review summarizes an algorithm for thyroid disease and the latest pathogenesis that would be useful to generalist and subspecialty physicians and others providing care for patients with this condition.

Abstract
Traditional Chinese medicine (TCM) processing is the summary of long-term clinical experience, processing can change the property, taste and meridian of TCM, achieve the purpose of reducing toxicity and increasing efficiency, to ensure the safety of clinical medication. This paper summarizes the research advance of salt processing in recent years from the aspects of the types of excipients, salt processing methods, salt processing purpose and the influence of salt process on the chemical composition, pharmacodynamic effect and in vivo behavior of TCM, and analyzes and discusses the shortcomings of the current research, so as to provide ideas for the further research and development of salt processing of TCM. The literatures were classified and summarized by consulting the scientific database (such as SciFinder Scholar, CNKI, Google Scholar, Baidu Scholar, etc.), Chinese herbal classics and Chinese Pharmacopoeia and so on. The results show that salt processing is helpful to introduce drugs into the kidney channel and enhance the effect of nourishing Yin and falling fire. The pharmacological effect, chemical composition and in vivo behavior of TCM will change after salt processing. In the future, we should strengthen the research on standardizing the dosage of excipients, the quality standard after processing, the relationship between the change of chemical composition after salt processing and the enhancement of pharmacological efficacy, so as to deeply explain the principle of salt processing, and further improve and optimize the salt making process. By combing the influence of the of salt processing of TCM and analyzed the current problems, we hope to provide guidance for the in-depth study of the salt processing mechanism of TCM and the inheritance and innovation of TCM processing technology.

Abstract
The purpose of this work was to illustrate the effect of processing with vinegar on saikosaponins of Bupleurum chinense DC. (BC) and the protective effects of saikosaponin A (SSA), saikosaponin b1 (SSb1), saikosaponin b2 (SSb2), and saikosaponin D (SSD) in lipopolysaccharide (LPS)-induced acute lung injury (ALI) mice. We comprehensively evaluated the anti-inflammatory effects and potential mechanisms of SSA, SSb1, SSb2, and SSD through an LPS-induced ALI model using intratracheal injection. The results showed that SSA, SSb1, SSb2, and SSD significantly decreased pulmonary edema; reduced the levels of IL-6, TNF-α, and IL-1β in serum and lung tissues; alleviated pulmonary pathological damage; and decreased the levels of the IL-6, TNF-α, and IL-1β genes and the expression of NF-κB/TLR4-related proteins. Interestingly, they were similar in structure, but SSb2 had a better anti-inflammatory effect at the same dose, according to a principal component analysis. These findings indicated that it may not have been comprehensive to only use SSA and SSD as indicators to evaluate the quality of BC, especially as the contents of SSb1 and SSb2 in vinegar-processed BC were significantly increased.

Abstract
Rheumatoid arthritis is a systemic autoimmune disease characterized by chronic symmetrical multiple arthritis. Current traditional counter-therapies are expensive and have side effects. Xanthii Fructus has effects in expelling wind and cold, draining the nasal orifice, and removing wind and dampness. However, its mechanism of action against rheumatoid arthritis is unknown. In this paper, the mechanism of the anti- rheumatoid arthritis effect of Xanthii Fructus is studied by proteomics. The experimental results show that it could significantly reduce serum inflammatory factor levels, alleviate joint edema, improve vasodilation and congestion, and significantly reduce the number of inflammatory cells. Proteomics results show that the PI3K-AKT signaling pathway is the key pathway for Xanthii Fructus to treat rheumatoid arthritis. In this study, we obtained a new understanding of the mechanism of Xanthii Fructus in the treatment of rheumatoid arthritis, which provided a theoretical basis for its prevention and treatment and laid the foundation for further research.

Abstract
Xanthii fructus (XF) is the dried and mature fruit of Xanthium sibiricum Patr. It has the effects of anti-inflammatory, antioxidant and anti-arthritic. Rheumatoid arthritis (RA) is the most common inflammatory disorder and often leads to disability. However, there are few studies on the treatment of RA by XF and the specific mechanism of treatment has not been clarified. This study was designed to explore the effects of proliferation and apoptosis by XF on human fibroblast-like synovial-RA (HFLS-RA) cells and investigate its mechanism. The cell proliferation ability was detected by MTS assay. Hoechst 33,342 staining was used to detect apoptosis, and the apoptosis rate was detected by flow cytometry. The expression levels of NF-κB p65 and β-catenin were detected by Western Blotting. MTS, Hoechst 33,342, flow cytometry analysis showed that the alcohol extract of XF inhibited human fibroblast-like synovial-RA cells proliferation and promoted apoptosis in a dose-dependent manner. Western Blotting experiment showed that the extract of XF could reduce the expression levels of NF-κB p65 and β-catenin. The extract of XF has a significant therapeutic effect on RA in vitro by regulating NF-κB signaling pathway and Wnt/β-catenin signaling pathway. Our research will help to clarify the potential pharmacological mechanism of XF on RA and provide experimental basis for the application of XF in clinical treatment.

HPLC-MS/MS analysis of primary alkaloids in rat plasma after oral administration of "Nux vomica - Glycyrrhiza glabra decoction": A pharmacokinetic study. JOURNAL OF ETHNOPHARMACOLOGY 2022; 298:115588. [PMID: 35931305 DOI: 10.1016/j.jep.2022.115588] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Revised: 07/15/2022] [Accepted: 07/27/2022] [Indexed: 06/15/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Decoction is the most common form of administering traditional Chinese medicine (TCM). During the preparation of decoction, the high temperature and complex chemical environment result in the formation of complex and multiple phases. The differences in drug components in different phases induce gastrointestinal absorption and physiological response. Nux vomica (Strychnos nux-vomica L) is a typical toxic TCM used in China, with remarkable pharmacological activity. In order to reduce its toxicity, nux vomica (NV) is often decocted with Glycyrrhiza glabra (GG) in clinic, and the detoxification mechanism has always been the focus of research interest. Most studies investigated the compatibility of NV-GG, but the in vivo behavior of individual constituents based on phase state has yet to be elucidated. AIM OF THE STUDY To investigate the pharmacokinetic behavior of typical toxic components in different phase states of "NV-GG decoction" in rat plasma. MATERIALS AND METHODS The sediment, suspension, colloid and true solution of "NV-GG decoction" was obtained via physical methods. The main components in different phase states were analyzed via reliable UFLC-Q-TOF-MS high-resolution mass spectrometry. A rapid and accurate HPLC-qqq-MS/MS method was established and validated for accurate determination of brucine and strychnine levels in plasma, followed by pharmacokinetic evaluation of different phase states of "NV-GG decoction" in rats. Kinetex F5 100A (50 mm × 3.0 mm, 2.6 μm) column was used for chromatographic separation. Aqueous solution containing acetonitrile and 0.1% formic acid was used as the mobile phase, followed by gradient elution at 0.4 mL/min. Mass spectra were detected by electrospray ionization (ESI) multiple reaction monitoring (MRM) in positive ion mode. RESULTS Fifteen different alkaloids were detected in different phase states of "NV-GG decoction". Strychnine and brucine, which are toxic components with high content, were selected for quantitative analysis. The established UPLC-qqq-MS/MS method is accurate and reliable with a good linearity (R2 > 0.99) in the respective concentration range, satisfying the quantitative requirements. The pharmacokinetic parameters of different phase states of rats differed significantly after gavage. The deposition phase was the most prominent. The index components showed higher Cmax, AUC0 and Tmax, while the T1/2, MRT, V/F and CL/F were the smallest, with a relatively slow plasma clearance rate in rats. The true solution group showed the lowest Tmax and the fastest absorption. CONCLUSION This method has been successfully utilized to study the pharmacokinetics of different phase states of "NV-GG decoction". Among the four phases, the deposition phase contributed to a large proportion of the in vivo kinetic behavior similar to that of sustained-release preparations, with slow absorption of toxic components and prolonged peak time. The pharmacokinetic parameters and plasma concentration-time curves of each phase can be used to study toxicity reduction of NV-GG and increase its biocompatibility.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Psoriasis is a chronic inflammatory dermatosis related to high morbidity and mortality. The incidence of psoriasis is increasing in recent decades. Some patients with psoriasis are anxious about the underlying side effects of synthetic drugs they are on. Therefore, they are eager to seek alternative and efficient therapy, such as Chinese herbal medicine (CHM). Researchers have found some CHM provides best source for the development of anti-psoriatic drugs because of their structural diversity and fewer adverse reactions. Some of CHM formulas or active constituents extracted from CHM have been rapidly developed into clinical drugs with good efficacy. At present, along with the CHM formulas, single CHM and its active components have been extensively accepted and utilized in the treatment of psoriasis, whose therapeutic mechanisms hitherto have not been thoroughly illustrated. AIM OF THE STUDY This review aimed to comprehensively summarize about the existing therapeutic mechanisms of CHM in the treatment of psoriasis and to provide a reference to develop future related studies in this field. MATERIALS AND METHODS Relevant literatures about how CHM treated psoriasis were acquired from published scientific studies (including PubMed, CNKI, Web of Science, Baidu Scholar, The Plant List, Elsevier and SciFinder). All plants appearing in the review have been included in The Plant List or Medicinal Plant Names Services (MPNS). RESULTS In this review, we collect numerous literatures about how CHM treats psoriasis via immune cells, signaling pathways and disease-related mediators and systematically elucidates potential mechanisms from the point of the suppression of oxidative stress, the inhibition of abnormal abnormal proliferation and differentiation, the inhibition of immune responses, and the suppression of angiogenesis. CONCLUSIONS Psoriasis is considered as a complicated disease caused by interaction among various mechanisms. The CHM formulas, single CHM and its active components have considerable positive reports about the treatment of psoriasis, which brings hope for a promising future of CHM in the clinical therapy of psoriasis. In the paper, we have concluded that the existing therapeutic mechanisms of CHM in the treatment of psoriasis.

Abstract
Eleutherococcus senticosus (Rupr. & Maxim.) Maxim. leaves (ESL) have long been people’s favorite as a natural edible green vegetable, in which phenols and saponins are the main characteristic and bioactive components. This study was first carried out to comprehensively analyze the phenols and saponins in ESL, including phytochemical, qualitative, quantitative, and bioactivity analysis. The results showed that 30 compounds, including 20 phenolic compounds and 7 saponins, were identified. Twelve of them were isolated from Eleutherococcus Maxim. for the first time. In the qualitative analysis, 30 phenolic compounds and 28 saponins were accurately detected. Their characteristic cleavage processes were described by UPLC-QTOF-MS/MS. Ten representative ingredients were quantitated in 29 different regions via a 4000 QTRAP triple quadrupole tandem mass spectrometer (UPLC-QTRAP-MS/MS), and it was found that S19 (69.89 ± 1.098 mg/g) and S1 (74.28 ± 0.733 mg/g) had the highest contents of total phenols and saponins, respectively. The newly developed analysis method for the quantitative determination was validated for linearity, precision, and limits of detection and quantification, which could be applied to the quality assessment of ESL. In vitro experiment, the α-glucosidase inhibitory effect of the phenolic fraction was higher than others, indicating that the phenolic content may be related to the hypoglycemic activity. It was also suggested that ESL could be developed as a natural potential effective drug or functional food.

Abstract
The present study aimed to assess the effects of epileptic treatment of the aerial part of Bupleurum chinense DC. in kainic acid (KA)-induced epilepsy rats and LPS-induced BV2 cells, as well as to identify the active chemical constituents. The in vivo and vitro results showed that 20% ethanol elution fractions of the aerial part of B. chinense DC. (BCE-20) and 70% ethanol elution fractions of the aerial part of B. chinense DC. (BCE-70) could improve the epileptic state of the rats and status epilepticus (SE%). Moreover, ultra-high-performance liquid chromatography (UPLC)-Orbitrap- mass spectrometry (MS) analysis identified BCE-20 and 70 as flavonoids and phenylpropanoids, respectively. The mechanistic analysis also showed that BCE-20 and 70 could regulate neurotransmitter abnormalities and suppresses the expression and secretion of pro-inflammatory cytokines. Notably, BCE-20 and 70 could regulate the Triggering receptor expressed on myeloid cells 2 (TREM2)/nuclear factor-k-gene binding (NF-κB)/inhibitor of NF-κB α (IκBα) pathway to inhibit the neuroinflammation. Our findings support the ethnopharmacological use of the constituent polyphenols and flavonoids from the aerial part of B. chinense DC., as the strong anti-epileptic agents.

Abstract
Three new flavonoid glycosides, Dasuanxinoside F-H (1-3), were isolated from the aerial parts of Allium sativum, together with eight known compounds which were firstly reported in this plant, including three flavonoid glycosides (4-6) and five phenylethanoid glycosides (7-11). Their structures were identified by UV-vis, IR, 1D and 2D NMR spectra, as well as HR-ESI-MS analyses. The inhibitory effect of the isolated compounds on platelet aggregation induced by adenosine diphosphate (ADP) was evaluated in vitro. The results showed that most compounds displayed different degrees of inhibition. Among them, 2, 5, 8 and 9 exhibited the strongest activity on platelet aggregation.

Comprehensive Metabolomics and Network Pharmacology to Explore the Mechanism of 5-Hydroxymethyl Furfural in the Treatment of Blood Deficiency Syndrome. Front Pharmacol 2022; 12:811331. [PMID: 35310893 PMCID: PMC8931835 DOI: 10.3389/fphar.2021.811331] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Accepted: 12/27/2021] [Indexed: 11/13/2022] Open
Abstract
Radix Rehmanniae (RR, from Radix Rehmanniae (Gaertn.) DC.) is a natural medicine used in traditional Chinese medicine (TCM) since ancient times for the treatment of blood disorders. RR is steamed to get Rehmanniae Radix Praeparata (RP), which has a tonic effect on blood; the content of 5-hydromethylfurfural (5-HMF) increases more than four times after steaming. Studies have shown that 5-HMF has positive pharmacological effects on cardiovascular and hematological disorders. This study aimed to explore and verify the impact of 5-HMF on rats with chemotherapy-induced blood deficiency syndrome (BDS). Rats were given cyclophosphamide (CP) and acetophenhydrazine (APH) to induce BDS, the coefficients of some organs (liver, spleen, and kidney) were measured, and a routine blood test examined the coefficients of several peripheral blood cells. Metabolomics and network pharmacology were combined to find important biomarkers, targets, and pathways. Western blot was used to detect the expression of CYP17A1 and HSD3B1 proteins in the spleen. All these findings suggested that the 5-HMF significantly increased the number of peripheral blood cells and reversed splenomegaly in rats. In addition, 5-HMF upregulated CYP17A1 and HSD3B1 protein expression in splenic tissues. Also, 5-HMF ameliorated chemotherapy-induced BDS in rats, and its therapeutic mechanism might depend on steroid hormone biosynthesis and other pathways. It acts on blood deficiency via multiple targets and pathways, which is unique to Chinese medicine.

A comprehensive review of research progress on the genus Arisaema: Botany, uses, phytochemistry, pharmacology, toxicity and pharmacokinetics. JOURNAL OF ETHNOPHARMACOLOGY 2022; 285:114798. [PMID: 34780984 DOI: 10.1016/j.jep.2021.114798] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/10/2021] [Revised: 09/07/2021] [Accepted: 11/01/2021] [Indexed: 06/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The genus Arisaema belongs to the family Araceae, which includes Chinese herbal medicines with wide-ranging pharmacological functions, including those useful for the treatment of stubborn phlegm, cough, epilepsy, tetanus, snakebite, rheumatoid arthritis, and other ailments. AIM OF THE STUDY The current study aimed to comprehensively review the botany, uses, phytochemistry, pharmacology, toxicity, quality control and pharmacokinetics of plants in the genus Arisaema and to provide novel insights to develop future research in this field. MATERIALS AND METHODS Relevant information on the genus Arisaema was obtained from published scientific materials (including materials from PubMed, Elsevier, Web of Science, Google Scholar, Baidu Scholar, CNKI, and Wiley) and other literature sources (e.g., the Chinese Pharmacopoeia, 2020 edition; Chinese herbal books and PhD and MSc thesis). RESULTS The application information complied with this review and included processing techniques, traditional uses, clinical applications and classic prescriptions. Approximately 260 compounds, including flavonoids, alkaloids, saccharides, steroids, fatty acids, amino acids and volatile oils, have been separated and identified from the genus Arisaema. The isolated compounds exhibit wide-ranging pharmacological activities such as antitumor activity, analgesic and sedative activity, antioxidant activity and anti-inflammatory activity. The toxicity and irritant impacts, quality control, and pharmacokinetics are also discussed in this review. CONCLUSIONS Plants in the genus Arisaema are valuable resources with therapeutic potential for a broad spectrum of ailments. Based on the limited literature, this review comprehensively and systematically summarizes current knowledge regarding the genus Arisaema for the first time. However, there have been insufficient studies on the active ingredients and germplasm and insufficient in-depth mechanistic studies. Therefore, isolation and identification of additional effective components and through research on the germplasm, pharmacodynamic mechanisms, and toxicology should be conducted to assess effectiveness and safety and to ensure the quality of the related drugs.
