Braz J Med Biol Res 2024; 57:e13238. [PMID: 38808885 PMCID: PMC11136484 DOI: 10.1590/1414-431x2024e13238] [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: 01/03/2024] [Accepted: 04/15/2024] [Indexed: 05/30/2024] Open
Abstract
Osteoarthritis (OA) is a highly prevalent joint disorder characterized by progressive degeneration of articular cartilage, subchondral bone remodeling, osteophyte formation, synovial inflammation, and meniscal damage. Although the etiology of OA is multifactorial, pro-inflammatory processes appear to play a key role in disease pathogenesis. Previous studies indicate that electroacupuncture (EA) exerts chondroprotective, anti-inflammatory, and analgesic effects in preclinical models of OA, but the mechanisms underlying these potential therapeutic benefits remain incompletely defined. This study aimed to investigate the effects of EA on OA development in a rat model, as well as to explore associated molecular mechanisms modulated by EA treatment. Forty rats were divided into OA, EA, antagomiR-214, and control groups. Following intra-articular injection of monosodium iodoacetate to induce OA, EA and antagomiR-214 groups received daily EA stimulation at acupoints around the knee joint for 21 days. Functional pain behaviors and chondrocyte apoptosis were assessed as outcome measures. The expression of microRNA-214 (miR-214) and its downstream targets involved in apoptosis and nociception, BAX and TRPV4, were examined. Results demonstrated that EA treatment upregulated miR-214 expression in OA knee cartilage. By suppressing pro-apoptotic BAX and pro-nociceptive TRPV4, this EA-induced miR-214 upregulation ameliorated articular pain and prevented chondrocyte apoptosis. These findings suggested that miR-214 plays a key role mediating EA's therapeutic effects in OA pathophysiology, and represents a promising OA treatment target for modulation by acupuncture.

Abstract
In this study, the active ingredients of 15 Chinese herbal medicines of Duhuo Jisheng Decoction and their corresponding targets were obtained from the Traditional Chinese Medicine Systems Pharmacology (TCMSP) database. The microarray data of Osteoarthritis (OA) were obtained through the GEO database for differential analysis and then a drug target-OA-related gene protein-protein interaction (PPI) network was established. The potential targets of Duhuo Jisheng Decoction in the treatment of OA were acquired by intersecting the OA-associated genes with the target genes of active ingredients. Random walk with restart (RWR) analysis of PPI networks was performed using potential targets as seed, and the top 50 genes of affinity coefficients were used as key action genes of Duhuo Jisheng Decoction in the treatment of OA. A drug-active ingredient-gene interaction network was established. AKT1, a key target of Duhuo Jisheng Decoction in the treatment of OA, was obtained by topological analysis of the gene interaction network. Molecular docking and molecular dynamics verified the binding of AKT1 to its corresponding drug active ingredients. CETSA assay demonstrated that the combination of luteolin and AKT1 increased the stability of AKT1, and the combination efficiency was high. In conclusion, the molecular mechanism of Duhuo Jisheng Decoction in treating OA featured by multiple components, targets, and pathways had been further investigated in this study, which is of significance for discovering as well as developing new drugs for this disease. The findings can also offer personalized diagnosis and treatment strategies for patients with OA in clinical practice.

Int Immunopharmacol 2023; 124:110844. [PMID: 37647678 DOI: 10.1016/j.intimp.2023.110844] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Revised: 08/07/2023] [Accepted: 08/20/2023] [Indexed: 09/01/2023]
Abstract
Intervertebral disc degeneration (IVDD) is one of the leading causes of lower back pain and the most common health problem in the world. Inflammasomes, which is mainly caused by NLRP3, mediated nucleus pulposus pyroptosis has been discovered to be strongly related to IVDD. In addition, Duhuo Jisheng Decoction (DHJSD) has anti-inflammatory and regulatory effects on NLRP3 inflammasome, but the molecular mechanism of whether DHJSD can regulate pyroptosis through NLRP3 to treat IVDD is unclear. In this study, we used a bioinformatics way to discover the molecular mechanism of DHJSD regulation of pyroptosis in IVDD, and validated our predictions through vitro and vivo experiments. Through bioinformatics, we found that NLRP3, GSDMD, IL-1βand other hub proteins of pyroptosis were highly expressed in IVDD SD rats, and network pharmacology discovered that DHJSD may control cellular senescence, apoptosis, and pyroptosis in order to treat IVDD. Additional findings demonstrated that DHJSD could successfully treat IVDD brought on by imaging and histomorphological analysis. Western blot showed that NLRP3, a key protein of pyroptosis, was elevated in rat degenerated nucleus pulposus tissue and lipopolysaccharide-treated Nucleus pulposus Cells (NPCs), and that DHJSD intervention was effective in reducing LPS-induced inflammatory responses and further suppressing the expression of pyroptosis related proteins to improve IVDD. The specific mechanism is that DHJSD inhibits NPCs pyroptosis via the SDF-1/CXCR4-NF-kB-NLRP3 axis. In conclusion, we revealed the intrinsic mechanism of DHJSD regulation of NPCs pyroptosis to improve IVDD and its intrinsic value for IVDD treatment.

Efficacy and Safety of Korean Herbal Medicine for Patients with Post-Accident Syndrome, Persistent after Acute Phase: A Pragmatic Randomized Controlled Trial. Healthcare (Basel) 2023; 11:healthcare11040534. [PMID: 36833066 PMCID: PMC9957496 DOI: 10.3390/healthcare11040534] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Revised: 01/31/2023] [Accepted: 02/01/2023] [Indexed: 02/15/2023] Open
Abstract
This is a pragmatic, two-armed, parallel, single-center, randomized controlled clinical trial for comparative evaluation between the effectiveness of integrated Korean medicine (IKM) and herbal medicine treatment with that of IKM monotherapy (control) for post-accident syndrome persistent after the acute phase. Participants were randomized into Herbal Medicine (HM, n = 20) and Control groups (n = 20) to receive the allocated treatment of 1-3 sessions/week for 4 weeks. Intention-to-treat analysis was conducted. The Difference of Numeric Rating Scale (NRS) change of overall post-accident syndromes from baseline to week 5 for the two groups was 1.78 (95% CI: 1.08-2.48; p < 0.001). Regarding secondary outcomes, a significant decrease compared to the baseline values was confirmed for NRS of musculoskeletal, neurological, psychiatric complaints and general symptoms of post-accident syndromes. In a survival analysis based on the recovery criteria of "patients with a reduction in the NRS of overall post-accident syndromes of ≥50%," the HM group showed a shorter time to recovery than the control group during the 17-week study period (p < 0.001 by the log-rank test). IKM combined with herbal medicine treatment significantly improved the quality of life by relieving somatic pain and alleviating the overall post-accident syndrome persistent after the acute phase; this effect was maintained for at least 17 weeks.

Abstract
Objective To explain the potential mechanisms of Drynariae Rhizoma (DR) in the treatment of low back pain (LBP). Design Network pharmacology was used to reveal the potential mechanisms including collecting the active ingredients of DR, analyzing the common gene targets of LBP and DR, constructing protein-protein interaction (PPI) network, collecting protein classification, performing Gene Ontology (GO) functional analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, and verifying significant gene targets. Results 234 different gene targets and 18 active compounds altogether were obtained. AKT1, VEGFA, and HIF1A were deemed to be major gene targets based on the degree values. According to GO analysis, steroid metabolic process involved 42 (18.10%) potential therapeutic LBP targets, neuronal cell body involved 24 (10.30%) potential therapeutic LBP targets, and protein serine/threonine kinase activity involved 28 (12.02%) potential therapeutic LBP targets in biological process (BP), cellular component (CC), and molecular function (MF), respectively. According to KEGG and pathway interaction analyses, the PI3K-Akt signaling pathway involved 34 (15.89%) potential therapeutic LBP targets, and PI3K-Akt signaling pathway played a significant role in the treatment of LBP. The mRNA expression levels of AKT1 and HIF1A were upregulated in healthy nucleus pulposus (NP) tissue than in degenerative NP tissue. In contrast, the mRNA expression level of VEGFA was downregulated in healthy NP tissue than in degenerative NP tissue. Conclusions In this study, we identified a potential relationship between LBP and DR in this work, as well as a synergistic mechanism of DR in the treatment of LBP, which serves as a benchmark for further in vivo and in vitro research.

Fuzi decoction ameliorates pain and cartilage degeneration of osteoarthritic rats through PI3K-Akt signaling pathway and its clinical retrospective evidence. PHYTOMEDICINE 2022; 100:154071. [PMID: 35378415 DOI: 10.1016/j.phymed.2022.154071] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Revised: 03/17/2022] [Accepted: 03/19/2022] [Indexed: 02/05/2023]
Abstract
BACKGROUND Osteoarthritis (OA) is a difficult disease but the clinic lacks effective therapy. As a classic formula of traditional Chinese medicine (TCM), Fuzi decoction (FZD) has been clinically applied for treating OA-related syndromes, but its anti-OA efficacy and mechanism remain unclear. PURPOSE To experimentally and clinically determine the anti-OA efficacy of FZD and clarify the underlying mechanism. METHODS UPLC/MS/MS was applied to identify the main components of FZD. A monoiodoacetate (MIA)-induced OA rat model was employed to evaluate the in vivo efficacy of FZD against OA, by using pain behavior assessment, histopathological observation, and immunohistochemical analysis. Primary rat chondrocytes were isolated to determine the in vitro effects of FZD by using cell viability assay, wound healing assay, and real-time PCR (qPCR) analysis on anabolic/catabolic mRNA expressions. RNA sequencing (RNA-seq) and network pharmacology analysis were conducted and the overlapping data were used to predict the mechanism of FZD, followed by verification with qPCR and Western blot assays. Finally, a retrospective analysis was performed to confirm FZD's efficacy and safety in OA patients. RESULTS The UPLC/MS/MS result showed that FZD contained atractylenolide I, benzoylhypaconitine, benzoylmesaconitine, benzoylaconitine, hypaconitine, mesaconitine, aconitine, lobetyolin, paeoniflorin, and pachymic acid. The in vivo data showed that FZD restored the cartilage degeneration in MIA-induced OA rats by ameliorating pain behavior parameters, recovering histopathological alterations, benefitting cartilage anabolism (up-regulating Col2 expression), and suppressing catabolism (down-regulating MMP13 and Col10 expressions). The in vitro data showed that FZD increased cell viability and wound healing capacity of chondrocytes, and restored the altered expressions of anabolic and catabolic genes of chondrocytes. The overlapping results of RNA-seq and network pharmacology analysis suggested that PI3K/Akt signaling mediated the anti-OA mechanism of FZD, which was verified by qPCR and Western blot experiments. Clinically, the anti-OA efficacy and safety of FZD were confirmed by the retrospective analysis on OA patients. CONCLUSION The scientific innovation of this study was the determination of anti-OA efficacy of FZD by experimental and clinical evidence and the discovery of its mechanism by integrated RNA-seq, network pharmacology, and molecular experiments, which suggests FZD as a promising TCM agency for OA treatment.

Abstract
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.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE To determine whether adjuvant Chinese herbal medicine (CHM) treatment is associated with the risk of joint replacement in osteoarthritis (OA) patients. MATERIALS AND METHODS This retrospective study used a population-based national health insurance (NHI) database from 2000 to 2012 in Taiwan. A total of 125,023 newly diagnosed OA patients were selected from one million beneficiaries of longitudinal health insurance database. Based on applying ten selected frequently used CHM formulas for OA, patients were divided into CHM user and non-CHM user. One-CHM to four-non-CHM user were propensity score matched with age, gender, monthly income, urbanization, comorbidities, Nonsteroidal anti-inflammatory drugs (NSAIDs) and index year were adjusted to reduce selection bias and confounding. Cox regression model was used for comparing the hazard ratios (HR) for the risk of joint replacement and Kaplan-Meier curve for the proportion of joint replacement. RESULTS OA patients who were female, younger (20-60 years), higher income and lived in urbanization location were found to preferred using CHM. Younger CHM users had a lower adjusted HR (0.63) of the risk of joint replacement (95% confidence interval (CI) = 0.42-0.94). Compared to non-CHM user, HR among CHM users (≥225 days annually) is 0.48 (95% CI = 0.31-0.76). The proportion of joint replacement in younger non-CHM user began to rise notably with time (log-rank test, p = 0.026). However, this benefit by CHM did not apply to older (over 60 years) OA patients. CONCLUSION This study suggested that adjuvant CHM might be associated with a lower rate of joint replacement in OA patients. CHM therapy might be considered in OA patients to reduce the need of joint replacement.

Abstract
Osteoarthritis (OA) is a common disease characterized by cartilage degeneration. In recent years much attention has been paid to Traditional Chinese Medicine (TCM) since its treatments have shown efficacy for ameliorating cartilage degradation with mild side effects. Osteoking is a TCM prescription that has long been used in OA treatment. However, the exact mechanism of Osteoking are not fully elucidated. In the current study, destabilization of the medial meniscus (DMM)-induced OA mice was introduced as a wild type animal model. After 8 weeks of administration of Osteoking, histomorphometry, OARSI scoring, gait analysis, micro-CT, and immunohistochemical staining for Col2, MMP-13, TGFβRII and pSmad-2 were conducted to evaluate the chondroprotective effects of Osteoking in vivo. Further in vitro experiments were then performed to detect the effect of Osteoking on chondrocytes. TGFβRIICol2ER transgenic mice were constructed and introduced in the current study to validate whether Osteoking exerts its anti-OA effects via the TGF-β signaling pathway. Results demonstrated that in wild type DMM mice, Osteoking ameliorated OA-phenotype including cartilage degradation, subchondral bone sclerosis, and gait abnormality. Col2, TGFβRII, and pSmad-2 expressions were also found to be up-regulated after Osteoking treatment, while MMP-13 was down-regulated. In vitro, the mRNA expression of MMP-13 and ADAMTS5 decreased and the mRNA expression of Aggrecan, COL2, and TGFβRII were up-regulated after the treatment of Osteoking in IL-1β treated chondrocytes. The additional treatment of SB505124 counteracted the positive impact of Osteoking on primary chondrocytes. In TGFβRIICol2ER mice, spontaneous OA-liked phenotype was observed and treatment of Osteoking failed to reverse the OA spontaneous progression. In conclusion, Osteoking ameliorates OA progression by decelerating cartilage degradation and alleviating subchondral bone sclerosis partly via the TGF-β signaling pathway.

Abstract
Objective Lumbar disc herniation (LDH) is based on the degenerative changes of the intervertebral disc. Many drugs are used to treat and prevent LDH, including Western medicine and Chinese medicine. Duhuo Jisheng Decoction (DHJSD) is one of the most classic Chinese medicine prescriptions. The purpose of our meta-analysis is to evaluate the efficacy and safety of modified DHJSD in the treatment of LDH. Methods We searched multiple databases including PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI) databases, Wanfang Database, and Chinese Scientific Journal Database (VIP) to identify studies that met the inclusion criteria. This meta-analysis was registered at INPLASY with reference number ID: INPLASY202060053. Results Fourteen randomized controlled trials (RCTs) were identified, including 1560 patients. This meta-analysis showed that the total effective rate and cure rate of modified DHJSD are higher than those of diclofenac sodium enteric-coated tablets (total effective rate: RR = 1.18, 95% CI: 1.12 to 1.25, P < 0.0001, I2 = 0%; cure rate: RR = 1.60, 95% CI: 1.30 to 1.97, P < 0.00001, I2 = 2%), diclofenac sodium enteric-coated tablets plus ibuprofen and indomethacin (total effective rate: RR = 1.23, 95% CI: 1.11 to 1.37, P=0.0001, I2 = 0%; cure rate: RR = 1.58, 95% CI: 1.22 to 2.04, P=0.0005, I2 = 0%), and diclofenac sodium sustained-release capsule (total effective rate: RR = 1.49, 95% CI: 1.27 to 1.74, P < 0.00001, I2 = 0%; cure rate: RR = 10.07, 95% CI: 3.29 to 30.88, P < 0.00001, I2 = 5%). Modified DHJSD was also better than Western medicine (MD = −1.56, 95% CI: −2.42 to −0.70, P=0.0004, I2 = 74%) in terms of visual analogue scale (VAS) scores. Three RCTs showed no adverse events in the modified DHJSD group, but adverse events existed in the Western medicine group. Conclusion This meta-analysis showed that modified DHJSD had a more favorable effect on the treatment of LDH than Western medicine, and there were no obvious adverse events. More high-quality RCTs are needed to complement existing conclusions.

Abstract
BACKGROUND Knee osteoarthritis (KOA) is one of the most common chronic muscular diseases in old people. In recent years, people are more and more interested in the use of Chinese herbal medicine (CHM) in the treatment of KOA, such as kidney-tonifying and blood-activating medicinal herbs (KTBAMs) in the treatment of KOA. Many studies have confirmed that KTBAMs are effective in the treatment of KOA. However, it is still unknown whether KTBAMs and NSAIDs are more effective in the treatment of KOA. Therefore, we evaluated the efficacy and safety of KTBAMs and NSAIDs in the treatment of KOA. METHODS Randomized controlled trials (RCTs) from online databases including PubMed, Embase, the Cochrane Library, China National Knowledge Infrastructure, Chinese Scientific Journal Database, Wanfang Data, and Chinese Biomedical Literature Database that compared the efficacy of KTBAMs and NSAIDs in the treatment of KOA were retrieved. The main outcomes included the evaluation of functional outcomes, pain and adverse effects. The Cochrane risk of bias (ROB) tool was used to assess methodological quality. RESULTS The literature will provide a high-quality analysis of the current evidence supporting KTBAMs for KOA based on various comprehensive assessments including the total effective rate, visual analog scale scores, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Lequence scores, Knee Society Scale (KSS) scores, and adverse effects. CONCLUSION This proposed systematic review will provide up-to-date evidence to assess the effect of KTBAMs in the treatment for patients with KOA.

Are Kidney-Tonifying and Blood-Activating Medicinal Herbs Better than NSAIDs for Knee Osteoarthritis? A Systematic Review and Meta-Analysis. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 2019:9094515. [PMID: 31885673 PMCID: PMC6899304 DOI: 10.1155/2019/9094515] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/25/2019] [Revised: 09/19/2019] [Accepted: 09/25/2019] [Indexed: 01/12/2023]
Abstract
Objective To compare the efficacy and safety of kidney-tonifying and blood-activating medicinal herbs (KTBAMs) and nonsteroidal anti-inflammatory drugs (NSAIDs) in the treatment of knee osteoarthritis (KOA). Methods Randomized controlled trials (RCTs) from online databases that compared the efficacy of KTBAMs and NSAIDs in the treatment of KOA were retrieved. The main outcomes included the evaluation of functional outcomes, pain, and adverse effects. The Cochrane risk-of-bias (ROB) tool was used to assess methodological quality. Results A total of 38 RCTs (3994 participants) were included in our meta-analysis. We found that KTBAMs had a significantly higher total effective rate (P < 0.00001, risk ratio (RR) = 1.08, confidence interval (CI) = 1.05 to 1.11, I2 = 4%) and a lower gastrointestinal adverse reaction rate (P < 0.00001, RR = 0.36, CI = 0.24 to 0.53, I2 = 33%) than NSAIDs. KTBAMs showed greater improvements in the Knee Society Scale (KSS) scores (mean difference (MD) = 7.17, 95% CI 0.71 to 13.64, P=0.03). Regarding the visual analog scale (VAS) scores, WOMAC scores, and Lequence scores, there were no significant differences between the KTBAM group and the NSAID group. The GRADE quality level of this systematic review indicated that the very low-quality evidence showed that KTBAMs had a higher total effective rate, while the moderate-quality evidence showed that the adverse reactions of KTBAMs were lower and the KSS scores were higher. Low-quality evidence showed no significant differences in improving VAS scores, WOMAC scores, or Lequence scores. Conclusion KTBAMs were superior to NSAIDs in terms of a higher total effective rate, a lower adverse reaction rate, and a higher KSS score. There were no significant differences between KTBAMs and NSAIDs in improving VAS scores, WOMAC scores, and Lequence scores of patients with KOA. Therefore, KTBAMs may be an alternative effective method for treating KOA. However, high-quality, well-designed RCTs with long-term follow-up are still required.

Abstract
Jiawei Yanghe decoction (JWYHD) is a Traditional Chinese Medicine (TCM) formula for the treatment of osteoarthritis (OA), however the underlying mechanisms of action of JWYHD in OA are not fully explored. This study investigates how JWYHD protects cartilage from degradation via Wnt/β-catenin signaling pathway. The chondroprotective and anti-inflammatory effect of JWYHD on chondrocytes in vitro and on MIA-induced OA rat model in vivo were investigated. In vitro, JWYHD increased the chondrocyte viability against interleukin (IL)-1β-induced chondrocytes apoptosis and preserved glycosaminoglycans in the extracellular matrix. JWYHD promoted chondrocyte viability against apoptosis, decreased MMP-3, MMP-13, Caspase-3, Caspase-9 via Wnt/β-catenin signaling pathway in both IL-1β-induced and Licl-induced chondrocytes. The qRT-PCR and western blot results showed that mRNA and protein expressions of Wnt signaling pathway related genes β-catenin and CyclinD1, apoptosis related genes Casapase-3 and Caspase-9, collagen degradation related genes Metalloproteinase (MMP)-3 and MMP-13 were up-regulated, and Col2a1 was down-regulated on IL-1β-induced chondrocytes. Treatment with JWYHD reversed these effects in a dose-dependent manner. Licl was used as Wnt/β-catenin signaling pathway activator in chondrocytes to determine the molecular mechanisms. Activation of Wnt signaling pathway by Licl up-regulated β-catenin, CyclinD1, Axin2, Caspase-3, Caspase-9, MMP-3, MMP-13 and IL-1β. These effects were blocked by JWYHD treatment. Furthermore, 75 Sprawl-Dawley rats were used to verify the results obtained in vitro. A total of 75 rats were randomly divided into the control group (no MIA-induced OA, received intragastric administration of an equivalent amount of saline), the OA group (MIA-induced OA, received intragastric administration of an equivalent amount of saline), and the JWYHD treatment group (MIA-induced OA, received intragastric administration of an equivalent amount of various concentrations of JWYHD at 1.4/2.7/5.5 g/kg). After 8 weeks of administration, all rats were sacrificed. JWYHD decreased the MIA-induced up-regulation of β-catenin, CyclinD1, Caspase-3, Caspase-9, MMP-3 and MMP-13 protein expressions in cartilage. It was also demonstrated that JWYHD decreased serum and synovium pro-inflammatory cytokines, IL-1β, IL-6 and TNF-α in MIA-induced OA rats and ameliorated the cartilage degradation. Histopathological staining, macroscopic observation and micro-CT scan with 3-dimension remodeling showed a cartilage protective effect of JWYHD. In conclusion, JWYHD possess multiple capabilities including preventing chondrocyte apoptosis, preserving integrity of extracellular matrix and anti-inflammatory effect in the treatment of OA both in vitro and in vivo.

Abstract
Lower back pain (LBP) is the most common disease in orthopedic clinics world-wide. A classic Fangji of traditional Chinese medicine, Duhuo Jisheng Decoction (DHJSD), has been proven clinically effective for LBP but its therapeutic mechanisms remain unclear. We hypothesized that DHJSD might relieve LBP through inhibiting the exaggerated proinflammatory cytokines and extracellular matrix (ECM) degradation. Thus, we studied the effects of DHJSD on stromal cell-derived factor-1 (SDF-1)-induced inflammation and ECM degradation in human nucleus pulposus cells (hNPCs). The primary hNPCs were isolated from either degenerated human intervertebral disc (HID) of LBP patients or normal HID of lumbar vertebral fracture patients, and cultured in vitro. The cells were treated with SDF-1 (10 ng/mL) and subsequently with different concentrations (100-500 μg/mL) of DHJSD for 24 h, respectively. We found that application of DHJSD significantly antagonized the SDF-1-induced production of proinflammatory cytokines and reduction of aggrecan and type II collagen in the hNPCs. DHJSD also markedly reduced the SDF-1-induced increase of CXCR4 and p-p65 and inhibited the nuclear translocation of p65 in the hNPCs. DHJSD, CXCR4-siRNA, and NF-κB inhibitor (BAY11-7082) caused the same inhibition of exaggerated proinflammatory cytokines in the SDF-1-treated hNPCs. These results provided compelling evidence that DHJSD may inhibit the generation of proinflammatory mediators and ECM degradation of HID through an orchestrated targeting at multiple molecules in the SDF-1/CXCR4/NF-κB pathway, thus offered novel mechanistic insights into the clinical effectiveness of DHJSD on LBP.

Abstract
INTRODUCTION Inducible nitric oxide synthase (iNOS) is the enzyme responsible for the production of nitric oxide (NO), a major proinflammatory and destructive mediator in osteoarthritis (OA). Areas covered: This is a comprehensive review of the recent literature on the involvement of iNOS in osteoarthritis and its potential to be used as a target for OA treatment. Evidence from in vitro, in vivo and human studies was systematically collected using medical search engines. Preclinical studies have focused on the effect of direct and indirect iNOS inhibitors in both animal and human tissues. Apart from direct inhibitors, common pharmacological agents, herbal and dietary medicines as well as hyperbaric oxygen, low level laser and low intensity pulsed ultrasound have been shown to exhibit a chondroprotective effect by inhibiting the expression of iNOS. Expert opinion: Data support the further investigation of iNOS inhibitors for the treatment of OA in human studies and clinical trials. Indirect iNOS inhibitors such as interleukin 1 inhibitors also need to be studied in greater detail. Finally, human studies need to be conducted on the herbal and dietary medicines and on the non-invasive, non-pharmacological treatments.

Abstract
Osteoarthritis (OA) is the most common joint disease among late middle-aged or elderly people. The pathological process of OA mainly involves the degeneration of cartilage tissue and deficiency of joint function. Salvianolic acid B (Sal B) is the main active ingredient of Salvia miltiorrhiza Bge, which possesses anti-inflammatory, anti apoptotic and other pharmacological activities. In this study, primary chondrocytes were cultured to investigate the effects of Sal B on the inflammatory response and apoptosis of OA induced by IL-1β, and to explore the possible mechanism. First, we determined the cytotoxicity of Sal B; the results showed that the cell activity of chondrocytes was not influenced by Sal B when the concentration was below 150 μM. Moreover, Sal B (40 and 80 μM) suppressed the expression of iNOS in OA chondrocytes induced by IL-1β, and restrained the secretion of NO, IL-6, IL-17 and TNF-α in chondrocytes obviously. Sal B (40, 80 μM) significantly alleviated the inhibitory effect of cell activity stimulated by IL-1β and up-regulated the expression of Col II and reduced the expression of Col X. Besides, Sal B down-regulated the expression level of Bax and promoted the expression of Bcl-2, showed a significant effect on promoting proliferation and inhibiting cell apoptosis. In addition, we found that IL-1β significantly reduced the ratio of p-PI3K/PI3K, p-Akt/Akt induced the nuclear translocation of AKT and inhibited the activation of the PI3K/Akt signaling pathway. Finally, the PI3K inhibitor, LY-294002, was added in IL-1β-induced chondrocytes. The results suggest that Sal B ameliorates IL-1β induced inflammation and suppresses apoptosis in OA by activating the PI3K/Akt signaling pathway. Our study reveals the mechanism of Sal B acts on OA and may provide a basis for the treatment of OA with Sal B. Osteoarthritis (OA) is the most common joint disease among late middle-aged or elderly people.![]()

Abstract
Cibotium barometz polysaccharides (CBPS) are one of the most important bioactive components extracted from the Cibotium barometz plant, which belongs to the Dicksoniaceae family. It has been widely used for the treatment of orthopedic diseases in traditional Chinese medicine. However, the molecular mechanisms behind the therapeutic effects of CBPS remain to be clarified. In the present study, the concentration of CBPS was detected by phenol-vitriol colorimetry. Furthermore, the effects stimulated by CBPS on the viability and G1/S cell cycle transition in primary chondrocytes from Sprague-Dawley rats were investigated. A cell viability assay demonstrated that chondrocyte proliferation may be enhanced by CBPS in a dose- and time-dependent manner. The mechanism underlying the promotion of chondrocyte cell cycle was suggested to involve the stimulation of G1 to S phase transition. To further confirm the results, reverse transcription-quantitative polymerase chain reaction and western blot analyses were used to detect the expression of mRNA and protein levels of cyclin D1, cyclin-dependent kinase 4 and retinoblastoma protein. The results suggested that CBPS may stimulate chondrocyte proliferation via promoting G1/S cell cycle transition. Since osteoarthritis is characterized by deficient proliferation in chondrocytes, the present study indicates that CBPS may potentially serve as a novel method for the treatment of osteoarthritis.

Insights into the Action Mechanisms of Traditional Chinese Medicine in Osteoarthritis. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2017; 2017:5190986. [PMID: 28203259 PMCID: PMC5292158 DOI: 10.1155/2017/5190986] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/16/2016] [Revised: 11/27/2016] [Accepted: 12/14/2016] [Indexed: 01/02/2023]
Abstract
Osteoarthritis (OA) is a chronic degenerative joint disease characterized by articular cartilage destruction, synovial inflammation, and osteophyte formation. No effective treatments are available. The current pharmacological medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) and analgesics, accompanied by possible adverse effects, might ameliorate OA symptoms. But they do not arrest the progression of OA. Traditional Chinese medicine (TCM) provides medical value by modification of disease and symptoms in OA. Valuable work on exploring TCM merits for OA patients has been investigated using modern technologies, although the complicated interacting network among the numerous components indicates the uncertainty of target specification. This review will provide an overview of the action mechanism of TCM in the last 5 years, discussing the TCM activities of anti-inflammation, antiapoptosis, antioxidation, anticatabolism, and proliferation in OA. TCM is a proposed medical option for OA treatment.

Du-Huo-Ji-Sheng-Tang Attenuates Inflammation of TNF-Tg Mice Related to Promoting Lymphatic Drainage Function. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2016; 2016:7067691. [PMID: 27239212 PMCID: PMC4863122 DOI: 10.1155/2016/7067691] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/30/2015] [Revised: 02/01/2016] [Accepted: 02/17/2016] [Indexed: 01/09/2023]
Abstract
To investigate whether Du-Huo-Ji-Sheng-Tang (DHJST) attenuate inflammation of RA related to lymphatic drainage function in vivo, we treated eight 3-month-old TNF-Tg mice with DHJST (12 g/kg) or the same volume of physiological saline once every day for 12 weeks, and 3-month-old WT littermates were used as negative control. After twelve weeks, we performed NIR-ICG imaging and found that DHJST increased the ICG clearance at the footpad and the pulse of efferent lymphatic vessel between popliteal lymph node and footpad. Histology staining at ankle joints showed that DHJST decreases synovial inflammation, bone erosion, cartilage erosion, and TRAP+ osteoclast area in TNF-Tg mice. Immunohistochemical staining by using anti-Lyve-1 and anti-podoplanin antibody showed that DHJST stimulated lymphangiogenesis in ankle joints of TNF-Tg mice. And zebrafish study suggested that DHJST promoted the formation of lymphatic thoracic duct. In conclusion, DHJST inhibits inflammation severity and promotes lymphangiogenesis and lymphatic drainage function of TNF-Tg mice.

BMJ Open 2016; 6:e008973. [PMID: 26729379 PMCID: PMC4716222 DOI: 10.1136/bmjopen-2015-008973] [Citation(s) in RCA: 49] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/04/2015] [Revised: 11/23/2015] [Accepted: 11/27/2015] [Indexed: 11/04/2022] Open
Abstract
OBJECTIVES Duhuo Jisheng decoction (DJD) is considered beneficial for controlling knee osteoarthritis (KOA)-related symptoms in some Asian countries. This review compiles the evidence from randomised clinical trials and quantifies the effects of DJD on KOA. DESIGNS 7 online databases were investigated up to 12 October 2015. Randomised clinical trials investigating treatment of KOA for which DJD was used either as a monotherapy or in combination with conventional therapy compared to no intervention, placebo or conventional therapy, were included. The outcomes included the evaluation of functional activities, pain and adverse effect. The risk of bias was evaluated using the Cochrane Collaboration tool. The estimated mean difference (MD) and SMD was within a 95% CI with respect to interstudy heterogeneity. RESULTS 12 studies with 982 participants were identified. The quality presented a high risk of bias. Meta-analysis found that DJD combined with glucosamine (MD 4.20 (1.72 to 6.69); p<0.001) or DJD plus meloxicam and glucosamine (MD 3.48 (1.59 to 5.37); p<0.001) had a more significant effect in improving Western Ontario and McMaster Universities Arthritis Index (total WOMAC scores). Also, meta-analysis presented more remarkable pain improvement when DJD plus sodium hyaluronate injection (MD 0.89 (0.26 to 1.53); p=0.006) was used. These studies demonstrated that active treatment of DJD in combination should be practiced for at least 4 weeks. Information on the safety of DJD or comprehensive therapies was insufficient in few studies. CONCLUSIONS DJD combined with Western medicine or sodium hyaluronate injection appears to have benefits for KOA. However, the effectiveness and safety of DJD is uncertain because of the limited number of trials and low methodological quality. Therefore, practitioners should be cautious when applying DJD in daily practice. Future clinical trials should be well designed; more research is needed.

Int J Mol Med 2015; 36:1519-28. [PMID: 26497741 PMCID: PMC4678159 DOI: 10.3892/ijmm.2015.2387] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2015] [Accepted: 10/08/2015] [Indexed: 12/15/2022] Open
Abstract
Chondrocyte apoptosis triggered by endoplasmic reticulum (ER) stress plays a vital role in the pathogenesis of osteoarthritis (OA). Bushen Zhuangjin decoction (BZD) has been widely used in the treatment of OA. However, the cellular and molecular mechanisms responsible for the inhibitory effects of BZD on chondrocyte apoptosis remain to be elucidated. In the present study, we investigated the effects of BZD on ER stress-induced chondrocyte apoptosis using a chondrocyte in vitro model of OA. Chondrocytes obtained from the articular cartilage of the knee joints of Sprague Dawley (SD) rats were detected by immunohistochemical staining for type II collagen. The ER stress-mediated apoptosis of tunicamycin (TM)-stimulated chondrocytes was detected using 4-phenylbutyric acid (4-PBA). We found that 4-PBA inhibited TM-induced chondrocyte apoptosis, which confirmed the successful induction of chondrocyte apoptosis. BZD enhanced the viability of the TM-stimulated chondrocytes in a dose- and time-dependent manner, as shown by MTT assay. The apoptotic rate and the loss of mitochondrial membrane potential (ΔΨm) of the TM-stimulated chondrocytes treated with BZD was markedly decreased compared with those of chondrocytes not treated with BZD, as shown by 4′,6-diamidino-2-phenylindole (DAPI) staining, Annexin V-FITC binding assay and JC-1 assay. To further elucidate the mechanisms responsible for the inhibitory effects of BZD on TM-induced chondrocyte apoptosis mediated by ER stress, the mRNA and protein expression levels of binding immunoglobulin protein (Bip), X-box binding protein 1 (Xbp1), activating transcription factor 4 (Atf4), C/EBP-homologous protein (Chop), caspase-9, caspase-3, B-cell lymphoma 2 (Bcl-2) and Bcl-2-associated X protein (Bax) were measured by reverse transcription-polymerase chain reaction (RT-PCR) and western blot analysis. In the TM-stimulated chondrocytes treated with BZD, the mRNA and protein expression levels of Bip, Atf4, Chop, caspase-9, caspase-3 and Bax were significantly decreased, whereas the mRNA and protein expression levels of Xbp1 and Bcl-2 were significantly increased compared with the TM-stimulated chondrocytes not treated with BZD. Additionally, all our findings demonstrated that there was no significant difference between the TM-stimulated chondrocytes treated with BZD and those treated with 4-PBA. Taken together, our results indicate that BZD inhibits TM-induced chondrocyte apoptosis mediated by ER stress. Thus, BZD may be a potential therapeutic agent for use in the treatment of OA.

Liu F, Weng X, Lin P, Zheng C, Xu H, Liu X, Ye H, Li X. Duhuo Jisheng decoction inhibits endoplasmic reticulum stress in chondrocytes induced by tunicamycin through the downregulation of miR-34a. Int J Mol Med 2015; 36:1311-8. [PMID: 26329269 DOI: 10.3892/ijmm.2015.2331] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2015] [Accepted: 07/13/2015] [Indexed: 11/05/2022] Open
Abstract
Our previous study showed that Duhuo Jisheng decoction (DHJSD) inhibited chondrocyte apoptosis by the mitochondria-dependent signaling pathway. Endoplasmic reticulum (ER) stress is upstream of the mitochondria-dependent signaling pathway and has been shown to promote chondrocyte apoptosis that occurs in osteoarthritis (OA). The present study aimed to evaluate whether DHJSD inhibits the chondrocyte apoptosis by regulating ER stress. DHJSD enhanced the viability of tunicamycin (TM)‑exposed chondrocytes, a model of ER stress-induced apoptosis, in a dose‑ and time‑dependent manner, as shown by MTT assay. The present results showed that DHJSD and sodium 4-phenylbutyrate (PBA), an ER stress inhibitor, reduced TM‑induced chondrocyte apoptosis by 4',6-diamidino‑2-phenylindole staining. To gain insight into the mechanisms of DHJSD that are responsible for enhancing the viability and inhibiting TM‑induced chondrocyte apoptosis, the associated mRNA expressions and protein levels were detected by reverse transcription‑polymerase chain reaction (RT‑PCR) and western blot analysis, respectively. The results showed that the expression levels of Xbp1, Xbp1s and Bcl‑2 were increased, and the expression levels of Bip, Atf4, Chop, Bax, caspase‑9 and ‑3 were decreased in the TM‑exposed chondrocytes treated with DHJSD or PBA compared with that in the TM‑exposed chondrocytes. To identify the possible mechanisms, the expression of miR‑34a was examined by the TaqMan microRNA assay, and was downregulated in the TM‑exposed chondrocytes treated with DHJSD or PBA compared with that in the TM-exposed chondrocytes. DHJSD inhibits ER stress in chondrocytes induced by exposure to TM by downregulating miR‑34a, suggesting that DHJSD may be a potential therapeutic agent for OA.
