Abstract
In this paper, the in vivo behavior of orthopedic implants covered with thin films obtained by matrix-assisted pulsed laser evaporation and containing bioactive glass, a polymer, and natural plant extract was evaluated. In vivo testing was performed by carrying out a study on guinea pigs who had coated metallic screws inserted in them and also controls, following the regulations of European laws regarding the use of animals in scientific studies. After 26 weeks from implantation, the guinea pigs were subjected to X-ray analyses to observe the evolution of osteointegration over time; the guinea pigs' blood was collected for the detection of enzymatic activity and to measure values for urea, creatinine, blood glucose, alkaline phosphatase, pancreatic amylase, total protein, and glutamate pyruvate transaminase to see the extent to which the body was affected by the introduction of the implant. Moreover, a histopathological assessment of the following vital organs was carried out: heart, brain, liver, and spleen. We also assessed implanted bone with adjacent tissue. Our studies did not find significant variations in biochemical and histological results compared to the control group or significant adverse effects caused by the implant coating in terms of tissue compatibility, inflammatory reactions, and systemic effects.

Int J Biol Macromol 2023; 253:127126.

Abstract
In this study, a porous sponge material was formed by physically mixing chitosan (CS) and Angelica sinensis polysaccharide (ASP). After removing the water by freeze-drying, the CS/ASP sponge was obtained. The prepared sponges exhibited excellent swelling properties, thermal stability and biocompatibility as well as improvements over the insufficient mechanical properties of pure chitosan sponges. Notably, the ASP released from the CS/ASP sponge could be effectively absorbed by the liver, which endowed the CS/ASP sponge with effective liver-protective effects against CCl4-induced acute liver injury; these protective effects surpassed those of both blank CS and CS/Dextran sponges. The underlying protective mechanism may involve the activation of the Nrf2-mediated antioxidant signaling pathway and the inhibition of hepatocyte apoptosis. Understanding CS/ASP sponges may provide new insights and inspire new methods for the clinical application of ASP. At the same time, we hope to suggest future directions for the development of polysaccharide preparations.

[PMID: 38137182 PMCID: PMC10743209 DOI: 10.3390/foods12244379] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Revised: 11/29/2023] [Accepted: 12/01/2023] [Indexed: 12/24/2023] Open
Abstract
Ginsenoside CK, a kind of rare ginsenoside transformed from protopanaxadiol saponins extracted from the genus Panax, has been proven to possess favorable bioactivities such as anti-inflammatory, anti-cancer, anti-diabetes, and hepatoprotective effects. The current study is targeted to determine the effect of ginsenoside CK on hepatitis induced by concanavalin A (Con A). Mice were treated with different dosages of ginsenoside CK for 7 days, and Con A (15 mg/kg) was intravenously injected to induce autoimmune hepatitis (AIH) after the last administration. The results demonstrated that pretreatment with ginsenoside CK (40 mg/kg) could obviously ameliorate the increase in serum indicators related to liver function such as AST, ALT, and ALP, and hepatic lesions induced by Con A. Meanwhile, ginsenoside CK suppressed hepatocyte apoptosis, which was observed in pathological data, and immunoblotting results showed that the expression of Bax, Bcl-2, and other proteins was regulated by CK. Furthermore, the release of inflammatory cytokines such as tumor necrosis factor-α (TNF-α) and IL-6 in mice with AIH were lowered by the administration of 40 mg/kg of ginsenoside CK. Furthermore, ginsenoside CK elevated the gene expression of Nrf2 and Sirt1 and augmented downstream target genes such as HO-1. In addition, a significant inhibition effect of the TLR4/NF-κB signal was observed in 40 mg/kg CK-pretreated mice compared with the model group. To sum up, the results indicated that ginsenoside CK has a notable hepatoprotective effect against AIH by activating Sirt1/Nrf2 and suppressing the TLR4/NF-κB signaling pathway.

Abstract
BACKGROUND Ginseng polysaccharides (GP) have been found to exhibit significant immune regulatory effects, making them a promising candidate for treating immune-related diseases. However, their mechanism of action in immune liver injury is not yet clear. The innovation of this study lies in exploring the mechanism of action of ginseng polysaccharides (GP) in immune liver injury. While GP has been previously identified for its immune regulatory effects, this study aims to provide a clearer understanding of its therapeutic potential for immune-related liver diseases. PURPOSE The purpose of this study is to characterize low molecular weight gingeng polysaccharides (LGP), investigate their effect on ConA-induced autoimmune hepatitis (AIH), and identify their potential molecular mechanisms. METHODS LGP was extracted and purified using water-alcohol precipitation, DEAE-52 cellulose column, and Sephadex G200. And its structure was analyzed. It was then evaluated for anti-inflammatory and hepatoprotective effects in ConA-induced cells and mice, assessing cellular viability and inflammation with Cell Counting Kit-8 (CCK-8), Reverse Transcription-polymerase Chain Reaction (RT-PCR), and Western Blot, and hepatic injury, inflammation, and apoptosis with various biochemical and staining methods. RESULTS LGP is a polysaccharide composed of glucose (Glu), galactose (Gal), and arabinose (Ara), with a molar ratio of 12.9:1.6:1.0. LGP has a low crystallinity amorphous powder structure and is free from impurities. LGP enhances cell viability and reduces inflammatory factors in ConA-induced RAW264.7 cells and inhibits inflammation and hepatocyte apoptosis in ConA-induced mice. LGP inhibits Phosphoinositide 3-kinase/protein kinase B (PI3K/AKT) and Toll-like receptors/Nuclear factor kappa B (TLRs/NF-κB) signaling pathways in vitro and in vivo to treat AIH. CONCLUSIONS LGP was successfully extracted and purified, exhibiting potential as a treatment for ConA-induced autoimmune hepatitis due to its ability to inhibit the PI3K/AKT and TLRs/NF-κB signaling pathways and protect liver cells from damage.

Myeloid-derived suppressor cells ameliorate liver mitochondrial damage to protect against autoimmune hepatitis by releasing small extracellular vesicles. Int Immunopharmacol 2023; 114:109540.

Abstract
BACKGROUND Autoimmune hepatitis (AIH) is an inflammatory liver disease that is associated with impaired self-tolerance. Myeloid-derived supprfessor cells (MDSCs) have been considered to exert counterregulatory effects on AIH. However, the specific mechanism underlying these effects is unclear. Herein, we investigated the efficacy and safety of MDSCs in protecting against AIH and explored the underlying mechanism. METHODS Circulating and liver MDSC expression levels in 71 AIH patients and 47 healthy control (HC) individuals were detected by flow cytometry and immunohistochemistry. The adoptive transfer of induced bone marrow-derived MDSCs (BM MDSCs) to AIH mice was used to explore the function of MDSCs. Hepatic injury and mitochondrial damage were evaluated by transaminase levels, histopathology, immunohistochemistry, transmission electron microscopy and western blotting. MDSCs were pretreated with the small extracellular vesicle (sEV) generation inhibitor GW4869 to explore the mechanism. Importantly, sEVs derived from MDSCs and MDSCs-GW4869 were injected into model mice to monitor mitochondrial function and biogenesis. RESULTS Circulating and liver MDSCs were expanded in AIH patients and mouse model. Furthermore, the follow-up data of AIH patients showed that immunosuppressive therapy further promoted the expansion of MDSCs. More importantly, the adoptive transfer of BM MDSCs to AIH mice effectively ameliorated liver injury and regulated the imbalance of the immune microenvironment. Additionally, BM MDSCs reduced liver mitochondrial damage and improved mitochondrial biogenesis. Mechanistically, sEVs derived from BM MDSCs showed the same biological effects as cells, and blocking sEV production weakened the function of BM MDSCs. Finally, multiple long-term administrations of BM MDSCs were proven to be safe in general. CONCLUSION In conclusion, MDSCs ameliorate liver mitochondrial damage to protect against autoimmune hepatitis by releasing small extracellular vesicles.

Paeoniflorin Upregulates Mitochondrial Thioredoxin of Schwann Cells to Improve Diabetic Peripheral Neuropathy Indicated by 4D Label-Free Quantitative Proteomics. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022; 2022:4775645. [PMID: 35340203 PMCID: PMC8956397 DOI: 10.1155/2022/4775645] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/05/2021] [Revised: 02/06/2022] [Accepted: 03/01/2022] [Indexed: 12/12/2022]
Abstract
Diabetic peripheral neuropathy (DPN) is a diabetic complication characterized by demyelination. The pathogenesis of DPN has not been fully elucidated, thus lacking therapies. In the current study, we aimed to confirm whether paeoniflorin (PF) could improve DPN by upregulating mitochondrial thioredoxin (Trx2) based on 4D Label-free proteomic experiments of Schwann cells (SCs) mitochondria. Firstly, PF increased the expression of mitochondrial processing peptidase α (Pmpca) and small ubiquitin-related modifier 1 (Sumo1) to increase mitochondrial protein processing of Trx2. Then, PF increased the protein expression of Trx reductase 2 (TrxR2) and peroxiredoxin 3 (Prx3), which belong to mitochondrial Trx systems. Accordingly, PF decreased mitochondrial reactive oxygen species (ROS) while increasing mtDNA and mitochondrial membrane potential to improve mitochondria function under high glucose environment. Furthermore, total glucosides of paeony capsules (TGP), containing more than 90% PF, increased the Trx2, TrxR2, and Prx3 levels in sciatic nerve of DPN rats, thus reducing demyelination as well as improving mechanical pain threshold, thermal pain threshold, motor nerve conduction velocity (MNCV), and sensor nerve conduction velocity (SNCV). Overall, these results suggest that PF could provide protection for DPN by upregulating Trx2.

Abstract
Total glucosides of paeony (TGP), an active ingredient extracted from the root of Paeonia alba, has been reported to display an anti-inflammatory effect. However, the effect of TGP on allergic rhinitis (AR) is still unknown. The present study aimed to assess the role of TGP in an AR mouse model. An AR mouse model was established using the ovalbumin method. The expression levels of Smad7/TGF-β pathway-related prtoeins in nasal mucosa tissues were determined by immunofluorescence, immunohistochemistry and western blotting. The severity of nasal allergic symptoms was detected by recording the frequency of sneezing and nose rubbing motions in all mice for 20 min. The levels of IgE and inflammatory cytokines, including IL-4, IL-5, IL-17 and IFN-γ, in the serum were measured by conducting ELISAs. H&E staining, periodic acid-Schiff staining and Masson staining were used to detected histopathological changes in mice. The concentrations of malondialdehyde and glutathione, and the activities of superoxide dismutase and catalase in tissue supernatant and serum were quantified using commercial assay kits. Apoptosis of nasal tissue cells was detected by performing TUNEL assays and western blotting. The expression of Smad7 was upregulated and that of TGF-β was downregulated in the nasal tissue of AR mice. Additionally, TGP regulated the Smad7/TGF-β pathway in the nasal tissue of AR mice. TGP alleviated serum IgE, nasal symptoms and histopathological changes in AR mice. Moreover, TGP ameliorated oxidative stress, cell apoptosis and inflammatory response. Smad7 small interfering RNA intervention aggravated the symptoms of AR mice via activation of the TGF-β pathway and reversed the protective effect of TGP in AR mice. TGP ameliorated oxidative stress, apoptosis and inflammatory response via the Smad7/TGF-β pathway in AR.

Abstract
Objectives: Plasmacytoid dendritic cells (pDCs) have been shown to have a role in autoimmune diseases, but their role in Autoimmune Hepatitis (AIH) is not completely clear. In the present study, we assessed the frequency of pDCs in peripheral blood of AIH patients under long-term standard immunosuppressive therapy. Methods: This cross-sectional analysis enrolled 27 AIH patients and 27 healthy controls. We analyzed and compared their proportion of pDCs, CD4+, CD8+, γδ T cells, CD25+ regulatory T (Treg) cells, FoxP3+, Foxp3+CD39+ Treg cells, total B (CD19+) cells, and plasma cells (CD38+) in peripheral blood using flow cytometry immunophenotyping. Results: AIH patients had a lower percentage of pDCs (median frequencies of 0.2% vs. 0.4%; p = .002) and higher expression of CD8 T cells (32.5% vs 28.6%; p = 0.008) in peripheral blood, when compared to healthy controls. We did not find statistically significant differences between the groups regarding the other cell subtypes.Conclusion: Our data suggest a persistent suppression of pDCs in AIH patients, along with increased CD8 T cell activity, years after AIH diagnosis and despite of good clinical response to treatment, thus pointing to a role of pDCs in the AIH pathogenesis.

Abstract
Screening functional food ingredients (FFI) from medicinal and edible plants (MEP) has still remained a great challenge due to the complexity of MEP and its obscure function mechanisms. Herein, an integrated strategy based on sequential metabolites identification approach, network pharmacology, molecular docking, and surface plasmon resonance (SPR) analysis was proposed for quickly identifying the active constituents in MEP. First, the sequential biotransformation process of MEP, including intestinal absorption and metabolism, and hepatic metabolism, was investigated by oral gavage, and intestinal perfusion with venous sampling method. Then the blood samples were analyzed by UPLC-Q Exactive Orbitrap HRMS. Second, the network pharmacology approach was used to explore the potential targets and possible mechanisms of the in vivo metabolites of MEP. Third, molecular docking and SPR approaches were used to verify the specific interactions between protein targets and representative ingredients. The proposed integrated strategy was successfully used to explore the heptoprotective components and the underlying molecular mechanism of Paeoniae Radix Alba (PRA). A total of 44 compounds were identified in blood samples, including 17 porotypes and 27 metabolites. The associated metabolic pathways were oxidation, methylation, sulfation, and glucuronidation. After further screening, 31 bioactive candidates and 377 related targets were obtained. In addition, the bioactive components contained in PRA may have therapeutic potentials for non-alcoholic fatty liver disease (NAFLD). The above results demonstrated the proposed strategy may provide a feasible tool for screening FFI and elaborating the complex function mechanisms of MEP.

Abstract
Metabolic syndrome (MetS) is a pathological state of many abnormal metabolic sections. These abnormalities are closely related to diabetes, heart pathologies and other vascular diseases. Danggui-Shaoyao-San (DSS) is a traditional Chinese medicine formula that has been used as a therapy for Alzheimer’s disease. DSS has rarely been reported in the application of MetS and its mechanism of how it improves gut microbia dysbiosis and hepatic lipid homeostasis. In this study, three extracts of DSS were obtained using water, 50% methanol in water and methanol as extracting solvents. Their chemical substances were analyzed by ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass (UPLC-Q/TOF-MS). Pharmacodynamic effect of the extracts were evaluated by comparison of biochemical factors, 16S rRNA sequencing test for gut microbiota analysis, as well as metabonomic and transcriptomic assessments on liver tissues from fructose-fed rats. This study aimed at investigating DSS’s mechanism of regulating blood lipid, anti-inflammation and reducing blood glucose. The results showed that the 50% methanol extract (HME) was more effective. It was worth noting that hydroxysteroid 17β-dehydrogenase 13 (HSD17β13) as a critical element of increasing blood lipid biomarker-triglyceride (TG), was decreased markedly by DSS. The influence from upgraded hydroxysteroid 17β-dehydrogenase 7 (HSD17β7) may be stronger than that from downgraded Lactobacillus in the aspect of regulating back blood lipid biomarker-total cholesterol (TC). The differential down-regulation of tumornecrosis factor alpha (TNF-α) and the significant up-regulation of Akkermansia showed the effective effect of anti-inflammation by DSS. The declining glycine and alanine induced the lowering glucose and lactate. It demonstrated that DSS slowed down the reaction of gluconeogenesis to reduce the blood glucose. The results demonstrated that DSS improved pathological symptoms of MetS and some special biochemical factors in three aspects by better regulating intestinal floras and improving hepatic gene expressions and metabolites.

Chang X, Zhang P, Xu XX, Pang B. Total Glucosides of Paeony Inhibited Autophagy and Improved Acute Kidney Injury Induced by Ischemia-Reperfusion via the lncRNA TUG1/miR-29a/PTEN Axis. DRUG DESIGN DEVELOPMENT AND THERAPY 2021; 15:2229-2242. [PMID: 34079224 PMCID: PMC8164873 DOI: 10.2147/dddt.s286606] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Accepted: 03/12/2021] [Indexed: 01/19/2023]
Abstract
Objective Total glucosides of paeony (TGP) has been proven to affect anti-inflammatory, immunomodulatory and hypoxia tolerance. This study investigates the effect of TGP on autophagy in acute kidney injury (AKI) induced by ischemia-reperfusion (I/R). Methods Rat model of AKI induced by I/R was established. Rats were administered with TGP at different doses by oral gavage. The contents of BUN, creatinine, NGAL, Kim-1 and IL-18 were detected. The levels of inflammatory factors (TNF-α, IL-1β and IL-6) and autophagy were measured. The expressions of lncRNA TUG1, miR-29a and PTEN were detected and their binding relationships were verified. I/R rat model with overexpressed TUG1 was established to explore the effect of TGP on kidney injury and autophagy. The hypoxia/reoxygenation (HR) model of HK-2 cells and the HR model of HK-2 cells overexpressing TUG1 and low-expressing PTEN were established. Results TGP decreased the contents of BUN, creatinine, NGAL, Kim-1 and IL-18, and reduced the levels of inflammatory factors. LncRNA TUG1 and PTEN were downregulated, and miR-29a was upregulated in kidney tissues. The binding relationships between lncRNA TUG1 and miR-29a, and miR-29a and PTEN were confirmed. TGP suppressed PTEN expression via the lncRNA TUG1/miR-29a axis. Overexpressing lncRNA TUG1 attenuated the protective effect of TGP on AKI and autophagy in HK-2 cells. TGP improved cell viability and inhibited the autophagy in HR model of HK-2 cells via lncRNA TUG1/miR-29a/PTEN axis. Conclusion TGP inhibited autophagy and improved AKI induced by I/R via the lncRNA TUG1/miR-29a/PTEN axis.

J Pharm Pharmacol 2021; 73:1039-1048. [PMID: 33749788 DOI: 10.1093/jpp/rgab025] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Accepted: 02/05/2021] [Indexed: 01/19/2023]
Abstract
OBJECTIVES The aim of the study was to explore the effect of total glucosides of paeony (TGP) and Tripterygium wilfordii polyglycosides (TWP) on erythrocyte methotrexate polyglutamates (MTXPGs), the metabolites of methotrexate (MTX). METHODS An ultra-high-performance liquid chromatography (UPLC)-tandem mass spectrometry (MS/MS) method was developed to determine MTXPGs. The effects of MTXPGs were analysed using 24 male Sprague-Dawley rats that were randomly divided into the MTX alone, MTX-TGP combined, and MTX-TWP combined groups. Rats were administered MTX at a dose of 0.9 mg/kg once a week, TGP at 0.054 g/kg and TWP at 1.8 mg/kg three times a day. Venous blood (1.0 ml) was collected at weeks 2, 4, 6, 9, 12 and 15 and then analysed using the developed UPLC-MS/MS method. KEY FINDINGS Specificity, linear range, inter-and intra-day precision, recovery, matrix effect and stability of MTXPGs met the standard regulations. This method was successfully used for the detection of MTXPGs. After administration of MTX alone, erythrocyte MTXPGs increased and accumulated in a time- and dose-dependent manner. Compared to MTX alone, the combination with TGP significantly decreased the content of total MTXPGs and short-chain MTXPGs (Methotrexate [MTX/MTXPG1] and 4-amino-10-methylpteroyldiglutamic acid [MTXPG2], P < 0.05), but had no significant effect on long-chain MTXPGs (4-amino-10-methylpteroyltriglutamic acid [MTXPG3], P > 0.05) and very long-chain MTXPGs (4-amino-10-methylpteroyltetraglutamic acid [MTXPG4] and 4-amino-10-methylpteroylpentaglutamic acid [MTXPG5], P > 0.05) at week 15. The combination of MTX with TWP had no significant effect on the content of total MTXPGs, short-chain MTXPGs and long-chain MTXPGs (P > 0.05), but it significantly decreased the content of very long-chain MTXPGs (P < 0.05) at week 15. CONCLUSIONS The UPLC-MS/MS method was successfully used to determine MTXPGs in rat erythrocytes. TGP and TWP in combination with MTX affected the production of MTXPGs of different chain lengths in erythrocytes.

Total glucosides of herbaceous peony (Paeonia lactiflora Pall.) flower attenuate adenine- and ethambutol-induced hyperuricaemia in rats. JOURNAL OF ETHNOPHARMACOLOGY 2020; 261:113054. [PMID: 32534113 DOI: 10.1016/j.jep.2020.113054] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/05/2019] [Revised: 05/19/2020] [Accepted: 05/30/2020] [Indexed: 06/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Herbaceous peony (Paeonia lactiflora Pall.) flower has been used widely in dietotherapy in China and other countries. It has good ethnopharmacological value in the treatment of various metabolic diseases. However, the molecular mechanisms by which it lowers serum uric acid are unknown. The development of pharmaceutical resources is very important. Here, we sought to elucidate the mode of action of herbaceous peony in terms of reducing uric acid levels. AIM OF THE STUDY In the present research, the effects of the total glucosides of herbaceous peony flower were investigated in a rat hyperuricaemia model. Another aim of the study was to clarify the mechanism by which herbaceous peony flower (TGPF) lowers serum uric acid levels. MATERIALS AND METHODS A hyperuricaemic rat model was induced via intragastric administration of 100 mg/kg adenine and 250 mg/kg ethambutol hydrochloride (EH) for 23 d. Then TongFengShu 600 mg/kg, allopurinol 42 mg/kg, or TGPF (50 mg/kg, 100 mg/kg, or 200 mg/kg) was administered 1 h after the adenine and EH treatments. RESULTS TGPF improved weight loss and decreased serum UA, XOD, MCP-1, TNF-α, Cr, and BUN in the rats with hyperuricaemic nephropathy. TGPF downregulated renal URAT1 and GLUT9, upregulated renal OAT1, and ameliorated histopathological changes in the thymus, spleen, and kidney. CONCLUSION TGPF is promising as a therapeutic agent against hyperuricaemia. It regulates the uric acid transporters and diminished serum uric acid levels, and alleviates renal pathology associated with hyperuricaemia.
