This study was conducted to identify whether the TLR4/MyD88/NF-κB signalling pathway plays a vital role in osteoarthritis (OA) treatment with Duhuo Jisheng Decoction (DHJSD) on the basis of a network pharmacology approach (NPA)-integrated experiment. Two experiments were conducted as follow: NPA for DHJSD using six OA-related gene series and the key pathway was screened out using NPA. NPA identified a vital role for the TLR4/MyD88/NF-κB signalling pathway in OA treatment with DHJSD, the conventional western blot analysis and qPCR confirmed it. Furthermore, changes of miR-146a-5p and miR-34a-5p in the cellular models were recovered by DHJSD administration, which synergistically contributed to OA therapy. The toll-like receptor signalling pathway and the NF-κB signalling pathway were meaningfully enriched by the miRNA-regulated gene pathways. This study identified and confirmed the TLR4/MyD88/NF-κB signalling pathway is an essential inflammatory signalling pathway in the DHJSD underlying OA treatment. The results provide a basis for further evaluation of the regulatory mechanism of the drug’s efficacy in treating OA.

Postmenopausal osteoporosis (PMOP) is an estrogen deficiency-induced bone loss, which has been shown an association with an altered gut microbiota (GM). Gut microbiota-bone axis has been recognized as a crucial mediator for bone homeostasis. Icariin (ICA) is an effective agent to delay bone loss by regulating the bone homeostasis. Thus, we hypothesize that ICA can prevent bone loss by modulating GM and regulating metabolite alterations. The effects of ICA on bone metabolism improvement in ovariectomized (OVX) rats and their relationships with the GM and fecal metabolites were investigated. Micro-computed tomography (micro-CT) and hematoxylin-eosin (HE) staining showed a typical bone boss in OVX group, while ICA or estradiol (E2) administration exhibited positive effects on bone micro-architecture improvement. The GM such as Actinobacteria, Gammaproteobacteria, Erysipelotrichi, Erysipelotrichales, Enterobacteriales, Actinomycetales, Ruminococcus and Oscillospira significantly correlated to serum bone Gla-protein (BGP), receptor activator of nuclear factor-κB (RANK), receptor activator of nuclear factor-κB ligand (RANKL), osteoprotegerin (OPG) and tartrate resistant acid phosphatase (TRACP). Further t-test revealed a substantial variation of the GM and fecal metabolites in different treatments. Among them, Lachnoclostridium, Butyricimonas, Rikenella, Paraprevolla, Adlercreutzia, Enterorhabdus, Anaerovorax, Allobaculum, Elusimicrobium, Lactococcus, Globicatella and Lactobacillus were probably the key microbial communities driving the change of bile acid, amino acid and fatty acid, thereby leading to an improvement of PMOP. The significant up-regulation of L-Saccharopine, 1-Aminocyclohexadieneacid and linoleic acid after ICA administration suggested important contributions of amino acid and fatty acid metabolisms in the prevention and treatment of PMOP. Taken together, our study has provided new perspectives to better understand the effects of ICA on PMOP improvement by regulating GM and the associated fecal metabolites. Our findings contribute to develop ICA as a potential therapy for PMOP.

This study aimed to identify whether the NF-κB signaling pathway plays a key role in the treatment of osteoarthritis (OA) with Bushen Zhuangjin Decoction (BZD) based on a typical network pharmacology approach (NPA). Four sequential experiments were performed: 1) conventional high-performance liquid chromatography (HPLC), 2) preliminary observation of the therapeutic effects of BZD, 3) NPA using three OA-related gene expression profiles, and 4) verification of the key pathway identified by NPA. Only one HPLC-verified compound (paeoniflorin) was identified from the candidate compounds discovered by NPA. The genes verified in the preliminary observation were also identified by NPA. NPA identified a key role for the NF-κB signaling pathway in the treatment of OA with BZD, which was confirmed by conventional western blot analysis. This study identified and verified NF-κB signaling pathway as the most important inflammatory signaling pathway involved in the mechanisms of BZD for treating OA by comparing the NPA results with conventional methods. Our findings also indicate that NPA is a powerful tool for exploring the molecular targets of complex herbal formulations, such as BZD.
A large volume sample stacking (LVSS) method in micellar electrokinetic chromatography (MEKC) with diode array detector was developed for the simultaneous separation and analysis of five compounds: protocatechuic acid, protocatechuic aldehyde, caffeic acid, syringetin and vanillin in Cibotium barometz. The electrophoretic separation was performed in a 10 mM sodium dodecyl sulfate (SDS) and 50 mM sodium borax-sodium dihydrogen phosphate system (pH = 8.5) with 10% methanol at a separation voltage of 30 kV after optimizing the typical parameters. The detection limits were from 32 pg to 65 pg, which were around 12–27 times lower than MEKC, and 500 times less than reported methods. Finally, the established method was validated to be applicable for the determination of protocatechuic acid and caffeic acid in Cibotium barometz. This proposed method is expected to facilitate the quality control of Cibotium barometz.

Knee osteoarthritis (KOA) is a common disease with no specific treatment. Icariin (ICA) is considered an agent for KOA. This study aimed to confirm the pain-related neuromodulation mechanisms of ICA on KOA. Three experiments were designed: (1) verifying the therapeutic effects of ICA in vivo and in vitro, (2) exploring the potential pain-related neuromodulation pathways involved in ICA treatment by functional magnetic resonance imaging (fMRI) and virus retrograde tracing (VRT) and (3) confirming the pain-related targets by tandem mass tag (TMT)-based quantitative proteomics and bioinformatic analyses. Experiment 1 verified the efficacy of ICA in OA animal and cell models. Experiment 2 found a series of brain regions associated with KOA reversed by ICA treatment, indicating that a pain-related hypothalamic-mediated neuromodulation pathway and an endocannabinoid (EC)-related pathway contribute to ICA mechanisms. Experiment 3 explored and confirmed four pain-related genes involved in KOA and ICA treatment. We confirmed the key role of pain-related neuromodulation mechanisms in ICA treatment associated with its analgesic effect. Our findings contribute to considering ICA as a novel therapy for KOA.

An enzyme-catalyzed fluorescence "switch" type sensor was constructed for the determination of alkaline phosphatase (ALP) activity by combining the fluorescence quenching effect of Ag+ on ultrathin g-C3N4 nanosheets (CNNSs) with the simple redox reaction of AA and Ag+. Briefly, Ag+ exhibits a significant quenching effect on the fluorescence of CNNSs. Thus the fluorescence signal of the CNNS-Ag+ system is extremely weak even in the presence of l-ascorbic acid-2-phosphate (AAP) ("off" state). When ALP coexists in the system, the enzyme can specifically catalyze the hydrolysis of AAP to form ascorbic acid (AA), which reduces Ag+ to Ag0. In this case, the fluorescence signal of the system is recovered ("on" state). Based on this principle, a signal-enhanced CNNS fluorescence sensor was developed to determine the activity of alkaline phosphatase. The experimental results show that the detection range of alkaline phosphatase is 0.5-20 U L-1, and the detection limit is 0.05 U L-1 (S/N = 3). Meanwhile, this method was used to assay ALP in serum samples.
膝为筋之府,以筋骨失衡为重要病理基础,临床以骨关节炎为多发.经筋是软组织复合结构的平衡体,足三阳、三阴经筋深聚于膝关节,从而维持关节的结构与功能.肌筋膜是维持肌肉-骨骼系统力学分配协调性及膝关节动静力平衡的整体结构.膝骨关节炎病理特点是筋骨失衡、以筋为先,筋-骨-筋失衡的恶性循环是其迁延进展的的主要因素.经筋与肌筋膜理论为膝骨关节炎的诊疗提供了理论依据,两者的核心理念一致,从整体观来揭示膝骨关节炎的生理、病理变化,为膝骨关节炎辨-防-治的一体化提供新的思路.因此,文章以经筋理论为切入点,借助肌筋膜理论,初探膝骨关节炎点-线-面的治疗方案,旨在为膝骨关节炎的防治提供新策略.
Objective:To explore the pharmacodynamic material basis, action targets and modes of Achyranthis Bidentatae Radix (Niuxi in Chinese) on the simultaneous treatment of Wei syndrome and Bi syndrome in osteoarthritis (OA) from the molecular level.Methods:①Seventy-three chemical components of Niuxi were retrieved from the databases of China National Knowledge Infrastructure (CNKI) and PubMed, and to built molecular dataset of Niuxi. Meanwhile, three drugs related to articular cartilage proteoglycan synthesis stimulation (the treatment for Wei syndrome) and twenty-eight drugs related to anti-inflammation analgesia (the treatment for Bi syndrome) on OA were searched from the DrugBank database, and their corresponding molecular datasets of treating Wei syndrome and Bi syndrome were also built. Based on the platforms of quantitative structure-activity relationship and principal component analysis, the distributions of the above datasets were analyzed in the chemical space.②Matrix metalloproteinase-1 (MMP-1), matrix metalloproteinase-3 (MMP-3), and transforming growth factor beta-1 (TGF-β1) were chosen as the targets of treating Wei Syndrome of OA, while interleukine-1 beta (IL-1β), interleukine-6 (IL-6), tumor necrosis factor-alpha (TNF-α) were chosen as the targets of treating Bi syndrome of OA. The platforms of molecular docking and biological network were used to study the interactions between the Niuxi compounds and above targets, and Niuxi compound-target networks related to the treatment of Wei syndrome and Bi syndrome were constructed to analyze the pharmacodynamic material basis, action targets and modes of Niuxi in the therapy of OA.Results:①Comparison of the chemical space distributions between molecular datasets of Niuxi and drugs indicated that the chemical space distributions of the former were more diverse than those of the latter, and the former were the same, or close to the latter with the treatment of Wei syndrome at the back of chemical space, while the former were the same, or close to the latter with the treatment of Bi syndrome at the bottom back corner of chemical space. These revealed the possible effects of Niuxi on Wei syndrome and Bi syndrome of OA.②The compound-target networks showed that the main pharmacodynamic material basis of Niuxi contained saponins, phytosterones, flavonoids and alkaloids. Meanwhile, the Niuxi compound numbers of treating Bi syndrome and Wei syndrome were thirty-seven and twenty-six, respectively. Among them, twenty compounds could simultaneously treating Bi syndrome and Wei syndrome of OA. The maximum number of targets interacting with them was six. Furthermore, in the compound-target network of Niuxi in treating Bi syndrome of OA, the key compound nodes of Niuxi were puerarin, baicalin, quercetin-3-O-rutinose and kaempferol-3-O-glucoside, which belonged to flavonoids, and the key target nodes were IL-1β and TNF-α. In the compound-target network of Niuxi in treating Wei syndrome of OA, the key compound node of Niuxi was baicalin, which belonged to flavonoids, and the key target node was MMP-1.Conclusion:Computer simulation intuitively showed the multi-target effects of Niuxi in simultaneously treating Wei syndrome and Bi syndrome of OA through the modes like promiscuous drug and combination drug. This could provide a basis for Niuxi therapeutic for OA and new drug development from Niuxi.

ETHNOPHARMACOLOGICAL RELEVANCE:Tougu Xiaotong capsules (TXC) are an herbal compound commonly used to treat osteoarthritis (OA) in China. AIM OF THE STUDY:We attempted to verify TXC's therapeutic effects and mechanisms related to the p38 mitogen-activated protein kinase (MAPK) pathway in vivo and in vitro. MATERIALS AND METHODS:TXC's therapeutic effects were assessed by observing cartilage degeneration and inflammatory factors in a modified Hulth's model (in vivo) and a lipopolysaccharides (LPS)-exposed cellular model (in vitro). The expression of biomarkers related to p38 MAPK pathway-mediated inflammation was also investigated. RESULTS:TXC treatment reversed cartilage degeneration related biomarkers (ADAMTS 4, ADAMTS 5, Col I, Col V, MMP 3, MMP 9, and MMP 13) and inflammation factors (IL-1β, TNF-α, and IL-6) in both the animal and cellular OA models. Expression of p-p38 MAPK was downregulated following TXC administration, and changes to microRNAs in the cellular models were recovered. These results indicated that the p38 MAPK pathway-related mechanism may involve therapeutic effects of TXC. CONCLUSIONS:This study verified TXC's efficacy to treat OA in vivo and in vitro and suggests that p38 MAPK pathway-related mechanisms may be involved in TXC's therapeutic effects.
