Network Pharmacology-Based Approach to Investigate the Active Ingredients and Therapeutic Mechanisms of Jingu Tongxiao Pill against Osteoarthritis. ACS OMEGA 2023; 8:31529-31540. [PMID: 37663478 PMCID: PMC10468769 DOI: 10.1021/acsomega.3c04724] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/02/2023] [Accepted: 07/28/2023] [Indexed: 09/05/2023]
Abstract
This study aimed to investigate the active ingredients and therapeutic mechanisms of Jingu Tongxiao Pill (JGTXP), a commonly used Chinese patent medicine, in treating osteoarthritis (OA) via network pharmacology analysis combined with experimental validation. First, we administered JGTXP to rat plasma and identified the candidate active compounds. Next, target prediction, protein-protein interaction, compound-target network construction, gene ontology (GO), and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses were conducted for JGTXP. Lastly, the network-derived key targets and pathways were validated in vitro and in vivo. Finally, we identified 106 compounds in JGTXP and 24 absorbed compounds in the rat plasma. Network analysis revealed that JGTXP interferes with OA mainly via regulating the inflammatory response, collagen catabolic process, and osteoclast differentiation, and the nuclear factor kappa B (NF-κB) signaling pathway plays a pivotal role in these processes. Experimentally, JGTXP exerted potential protective effects on articular cartilage and inhibited expression of inflammatory mediators and collagen catabolism-related proteins, including interleukin 1 beta (IL-1β), interleukin 6, tumor necrosis factor alpha (TNF-α), and matrix metalloproteinase (MMP) 3 and MMP13, in a papain-induced OA rat model. Consistently, mRNA expression levels of these factors and nitric oxide release were suppressed by JGTXP in an LPS-induced RAW 264.7 inflammation model. The reporter gene assay showed that JGTXP could reduce the transcriptional activity of NF-κB. Consecutive western blot analysis demonstrated that nuclear NF-κB p65, inducible nitric oxide synthase (iNOS), and cyclooxygenase 2 (COX-2) expression were inhibited while cytoplasmic NF-κB p65 was upregulated by JGTXP. Using a combination of chemical profiling, network pharmacology analysis, and experimental validation, we preliminarily clarified the active ingredients of JGTXP intervention for OA and demonstrated that JGTXP ameliorates OA, at least partially, by regulating the NF-κB signaling pathway.

Continuous care intervention with carbohydrate restriction improves physical function of the knees among patients with type 2 diabetes: a non-randomized study. BMC Musculoskelet Disord 2022; 23:297. [PMID: 35351093 PMCID: PMC8961996 DOI: 10.1186/s12891-022-05258-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2021] [Accepted: 03/22/2022] [Indexed: 11/29/2022] Open
Abstract
Background In a previous study, we assessed a novel, remotely monitored carbohydrate restricted diet regimen including nutritional ketosis in patients with type 2 diabetes and reported significant improvements in weight, glycemic control, abdominal fat and inflammation from baseline to 2 years. Knee outcome measures were collected as a secondary outcome in the trial. This study aims to assess the effect of this intervention on knee functional scores and to identify if changes in weight, central abdominal fat (CAF), glycemic status and high sensitivity C-reactive protein (hsCRP) were associated with its improvement. Methods This prospective analysis included continuous care intervention (CCI, n = 173) and usual care (UC, n = 69) trial participants with type 2 diabetes that reported knee pain at baseline. Knee outcome measures included the Knee injury and Osteoarthritis Outcome Score (KOOS) pain, symptoms, activities of daily living (ADL), sports and recreation function, and knee-related quality of life subscales, and total KOOS score were assessed from baseline to 2 years. Missing data at each time point were replaced with multiple imputation under the assumption of missing at random. To assess if the primary analysis of the knee scores changed under plausible missing not at random assumptions, sensitivity analysis was also performed using pattern mixture models. In CCI, we also assessed factors associated with the improvement of knee scores. Results In the primary analysis, CCI participants demonstrated a statistically significant improvement in total KOOS and all KOOS individual subscale scores at 1 year and maintained through 2 years as opposed to UC patients who showed no significant changes from baseline to 2 years. The significant improvement in total KOOS and its individual subscale scores from baseline to 2 years remained relatively stable in CCI in the sensitivity analysis under different missing not at random scenarios confirming the robustness of the findings from the primary analysis. Approximately 46% of the CCI participants met the 10 points minimal clinically important change at 2 years. A reduction in CAF was associated with improvement in total KOOS and KOOS ADL, while a decrease in hsCRP was associated with improvement in KOOS symptoms scores. Conclusion A very low carbohydrate intervention including nutritional ketosis resulted in significant improvements in knee pain and function among patients with T2D. The improvements in knee function were likely secondary to a reduction in central adiposity and inflammation. Future research on the applicability of this intervention in radiographically confirmed OA patients is important. Trial registration Clinical trial registration: NCT02519309 (10/08/2015).

Effects of motor imagery on strength, range of motion, physical function, and pain intensity in patients with total knee arthroplasty: A systematic review and meta-analysis. Braz J Phys Ther 2021; 25:698-708.

Abstract
BACKGROUND In the early stages of total knee arthroplasty (TKA) rehabilitation, in which physical function in general can be affected, motor imagery (MI) might play a relevant role. OBJECTIVE To assess the impact of MI on strength, active range of motion (ROM), pain intensity, and physical function in patients with TKA. METHODS We conducted a systematic review and meta-analysis of randomised controlled trials. Pooled effects were calculated as standardised mean differences (SMDs) and 95% confidence intervals (CIs) for the relevant outcomes using random effects model. The certainty of evidence was assessed with GRADE approach. RESULTS This review included 7 articles. The addition of MI to standard therapy, based on low quality of evidence, showed a moderate increase in quadriceps strength (4 studies; SMD: 0.88; 95% CI: 0.42, 1.34) and a small reduction in pain intensity (SMD: 0.63; 95% CI: 0.08, 1.19). It is unclear whether MI can provide beneficial effects for active ROM and function. CONCLUSIONS There is low to very low-quality evidence that adding an MI intervention to standard rehabilitation for patients with TKA may improve quadriceps strength and pain intensity, but the effects of MI on ROM and physical function is unclear.

Abstract
This paper aimed to study the biodegradation of collagen-containing waste (pork skin) induced by collagenase and Neutrase 1.5 MG enzymes and compare the amino acid, peptide, and carbohydrate composition of hydrolysis products. It was found that the degree of biodegradation of collagen-containing raw materials (pork skin) reached 78% when using an enzyme preparation (collagenase with a concentration of 250 U/g of the substrate) at pH 7.0, 40 °C, and a 360 min process duration. It was shown that the content of peptides with a molecular weight of 6.5–14.0 kDa in the hydrolysis products (collagenase) of collagen-containing wastes was 13.4 ± 0.40%, while in the products of hydrolysis (Neutrase 1.5 MG) it was 12.8 ± 0.38%. The study found that the hydrolysis products (Neutrase 1.5 MG) of collagen-containing raw materials contain fewer hexoses, free hexosamines, and hyaluronic acid than the hydrolysis products (collagenase) of collagen-containing raw materials. The content of chondroitin sulfates is practically the same in all samples of hydrolysis products. Proteases with collagenolytic activity are widely used in industry. Recently, they have increasingly been used in pharmaceutical, food, and other industries. Collagenases are promising enzymes for the production of chondroprotectors used for the treatment of osteoarthritis.

Abstract
Chondrocyte apoptosis contributes to osteoarthritis, while miR-146a is a critical player in chondrocyte apoptosis. Our bioinformatics analysis showed that miR-146a may bind with long non-coding RNA (lncRNA) CALML3 antisense RNA 1 (CALML3-AS1). Our study was therefore carried out to investigate the interactions between lncRNA CALML3-AS1 and miR-146a in osteoarthritis. This study included 66 osteoarthritis patients who were admitted at Shanxi People's Hospital from July 2016 to June 2019. Transfections were performed to analyse gene interactions. RT-qPCR and Western blot were performed to determine the expression levels of gene and protein, respectively. Cell apoptosis of chondrocytes induced by lipopolysaccharide (LPS) was analysed by cell apoptosis assay. We found that CALML3-AS1 was downregulated, while miR-146a was upregulated in osteoarthritis. However, no significant correlation was found between them. In addition, overexpression of CALML3-AS1 or miR-146a did not affect the expression of each other. However, overexpression of CALML3-AS1 resulted in the upregulation of Smad family member 4 (Smad4), a downstream target of miR-146a. We also found that the expression of miR-146a and Smad4 were negatively correlated, while the correlation between CALML3-AS1 and smad4 was not significant. In cell apoptosis assay, overexpression of CALML3-AS1 and Smad4 resulted in decreased proliferation of chondrocytes. MiR-146a played an opposite role and reduced the effects of overexpression of CALML3-AS1 and Smad4. Therefore, CALML3-AS1 may regulate chondrocyte apoptosis by acting as a sponge for miR-146a to upregulate Smad4.

Abstract
PURPOSE The purpose of this study is to determine the efficacy of amniotic suspension allograft (ASA) compared to hyaluronic acid (HA) and saline at up to 12 months of follow-up through the use of patient-reported outcomes, immunoglobulin levels, and anti-human leukocyte antigen (HLA) levels. METHODS Within this multicenter study, 200 patients were randomized 1:1:1 to a single intra-articular injection of saline, HA, or ASA. Patient-reported outcomes, including Knee Injury and Osteoarthritis Outcome Score (KOOS) and visual analog scale (VAS) score, were collected at multiple time points (baseline, 1 week, 6 weeks, 3 months, 6 months) out to 12 months to assess improvements in pain and function. Radiographs at baseline and 12 months were taken to determine radiographic changes, while blood was collected at baseline, 6 weeks, and 6 months to determine changes in immunoglobulins and anti-HLA levels. Statistical analyses were performed using last observation carried forward and mixed effects model for repeated measures. RESULTS Treatment with ASA resulted in significant improvements in KOOS and VAS scores that were maintained through 12 months (P < .05). Treatment with ASA resulted in a 63.2% responder rate at 12 months using the Outcome Measures in Arthritis Clinical Trials-Osteoarthritis Research Society International simplified definition. There were no significant differences between groups for radiographic measures in the index knee, immunoglobulins, C-reactive protein, or anti-HLA serum levels (P > .05). The number and type of adverse events (AEs) reported for ASA were comparable to the HA injection group, while no treatment-emergent AEs were reported for the saline group. CONCLUSIONS This randomized controlled trial of ASA vs HA and saline for the treatment of symptomatic knee osteoarthritis demonstrated clinically meaningful improved outcomes with ASA over the controls out to 12 months postinjection. No concerning immunologic or adverse reactions to the ASA injection were identified with regards to severe AEs, immunoglobulin, or anti-HLA levels. LEVEL OF EVIDENCE Level I, randomized controlled multicenter trial.

Abstract
Osteoarthritis (OA) is a common age‑related joint disorder, for which no effective disease‑modifying drugs are currently available. Long non‑coding RNAs (lncRNAs) are involved in the occurrence of OA. lncRNA small nucleolar RNA host gene 16 (SNHG16) has been reported to regulate inflammation; however, the exact biological function of SNHG16 in OA and its underlying mechanism of action remain unclear. In this study, gene and protein expression levels were detected using reverse transcription‑quantitative PCR and western blotting, respectively. Cell apoptosis was analyzed using flow cytometry and ELISA was performed to detect TNF‑α levels. The interactions between lncRNA SNHG16 and microRNA (miR)‑373‑3p were examined using the dual‑luciferase reporter assay. lncRNA SNHG16 was upregulated in OA tissue compared with normal joint tissue. The expression levels of collagen II were significantly reduced in OA tissue compared with normal tissue. Similarly, aggrecan expression levels were significantly reduced in IL‑1β‑treated CHON‑001 cells compared with the controls. In addition, the protein expression levels of MMP13 were significantly increased in OA tissues and IL‑1β‑treated CHON‑001 cells compared with the controls. SNHG16 knockdown significantly increased the expression levels of aggrecan, and decreased the expression levels of MMP13, cleaved caspase‑3 and p21 in IL‑1β‑treated CHON‑001 cells. In addition, IL‑1β induced CHON‑001 cell apoptosis, while SNHG16 knockdown decreased IL‑1β‑induced apoptosis. Furthermore, the luciferase activity assay suggested that SNHG16 negatively regulated miR‑373‑3p in OA. Finally, the results suggested that the proinflammatory effect of IL‑1β on CHON‑001 cells was significantly reduced by SNHG16 knockdown. In conclusion, lncRNA SNHG16 knockdown significantly limited the progression of OA by sponging miR‑373‑3p in vitro, which suggested that SNHG16 may serve as a potential therapeutic target for OA.

Mol Med Rep 2020; 22:5313-5325.

Abstract
Osteoarthritis is a chronic degenerative joint disease. Long non‑coding RNA plasmacytoma variant translocation 1 (PVT1) is involved in the progression of osteoarthritis and exosomes serve a central role in intercellular communication. However, whether PVT1 can be mediated by exosomes in osteoarthritis has not been reported. Whole blood was drawn from osteoarthritis patients and healthy volunteers. Lipopolysaccharide (LPS) was used to stimulate human normal chondrocytes (C28/I2) to construct a cell damage model in vitro. Protein levels were examined via western blot analysis. eThe expression of PVT1, microRNA (miR)‑93‑5p and high mobility groupprotein B1 (HMGB1) was evaluated through reverse transcription‑quantitative PCR. Cell viability and apoptosis were determined through CCK‑8 or flow cytometric assay. Inflammatory cytokines were measured via ELISA. The relationship between PVT1 or HMGB1 and miR‑93‑5p was confirmed by dual‑luciferase reporter assay. PVT1, HMGB1 and exosomal PVT1 were upregulated while miR‑93‑5p was downregulated in osteoarthritis patient serum and LPS‑induced C28/I2 cells. Exosomes from osteoarthritis patient serum and LPS‑treated C28/I2 cells increased PVT1 expression in C28/I2 cells. PVT1 depletion reversed the decrease of viability and the increase of apoptosis, inflammation responses and collagen degradation of C28/I2 cells induced by LPS. PVT1 regulated HMGB1 expression via sponging miR‑93‑5p. miR‑93‑5p inhibition abolished PVT1 silencing‑mediated viability, apoptosis, inflammation responses and collagen degradation of LPS‑stimulated C28/I2 cells. HMGB1 increase overturned miR‑93‑5p upregulation‑mediated viability, apoptosis, inflammation responses and collagen degradation of LPS‑stimulated C28/I2 cells. Furthermore, PVT1 modulated the Toll‑like receptor 4/NF‑κB pathway through an miR‑93‑5p/HMGB1 axis. In summary, exosome‑mediated PVT1 regulated LPS‑induced osteoarthritis progression by modulating the HMGB1/TLR4/NF‑κB pathway via miR‑93‑5p, providing a new route for possible osteoarthritis treatment.

Abstract
BACKGROUND Degenerative knee osteoarthritis (KOA) shows an increase in morbidity with improvement in the living conditions and extended lifespans. Treatment for degenerative KOA has been gaining attention since it significantly affects the life of the elderly population and is also associated with increased expenses for medical services and high socioeconomic costs. Treatments for degenerative KOA include nondrug therapy, drug therapy, and surgical treatment. For cases that show little response to conservative treatment but have not involved severe deformation of the knee, procedures such as arthroscopic surgery, autologous chondrocyte implantation, or autologous osteochondral transplantation can be performed. However, effective treatment is required for patients experiencing sustained knee pain after surgery. Although studies confirming the therapeutic effects of acupuncture or thread-embedding acupuncture (TEA) treatment for degenerative KOA have been reported, clinical studies on a combination of TEA and electroacupuncture (EA) in patients complaining of knee pain after arthroscopic surgery, autologous chondrocyte implantation, or autologous osteochondral transplantation have not yet been reported. Therefore, this study aimed to evaluate the effectiveness and safety of this combination treatment in patients with persistent knee pain after arthroscopic surgery, autologous chondrocyte implantation, or autologous osteochondral transplantation. METHODS/DESIGN This study has been designed as a 2-group, parallel, single-center, randomized, controlled, assessor-blinded trial. Thirty-six patients with degenerative KOA who complained of pain even after arthroscopic surgery, autologous chondrocyte implantation, or autologous osteochondral transplantation will be randomized to either the (TEA + EA + Usual care) group or the (Usual care only) group in a 1:1 ratio. The patients in the (TEA + EA + Usual care) group will receive TEA treatment once a week for 4 weeks for a total of 4 sessions and EA twice a week for a total of 8 sessions while continuing usual care. The (Usual care only) group will only receive usual care for 4 weeks. To assess the efficacy of the TEA and EA combination treatment, the visual analogue scale, the Korean version of the Western Ontario and McMaster Universities Osteoarthritis Index, the EuroQol 5-Dimension 5-Level, and the doses of the rescue drug taken will be evaluated at baseline (1W) and weeks 2 (2W), 4 (4W), 6 (6W), and 8 (8W). The primary efficacy endpoint is the mean change in visual analogue scale at week 4 (4W) compared to baseline. Adverse events will be assessed at every visit. DISCUSSION This study will provide useful data for evaluating the clinical efficacy and safety of TEA and electroacupuncture combination treatment for improving pain and quality of life after surgery for degenerative KOA.

Abstract
PURPOSE Knee osteoarthritis (OA) is a musculoskeletal disorder that may have a heavy impact on the patients' quality of life. Intra-articular collagen injection may be a safe adjuvant. Recently, CHondroGrid (CG), a hydrolyzed (< 3 kDa) bovine collagen injectable formulation, has been placed on the market. The aim of this study was to investigate the safety and performance profile of CG. METHODS Patients affected by Kellgren Lawrence grade 1 to 4 knee OA and BMI < 30 were treated by administering three CG injections of 2 ml (4 mg) each (at 15 days and 45 days from the first one, respectively) and were followed up for six months after the last administration. Clinical records were retrospectively assessed to compare VAS, Lequesne and WOMAC total, pain, stiffness, and physical function scores collected at baseline and 15, 45, and 225 days after the first injection. RESULTS At the last follow-up, 70 patients (37 men and 33 women, aged 57.1 ± 14.5 years) treated with CG showed a 50% reduction in their median Lequesne score, a 50% reduction in their VAS score at rest and moving, and a ≥ 50% reduction for all other scores under consideration. CONCLUSIONS CG may be a safe and effective adjuvant in the treatment of symptomatic knee OA.

Abstract
Multidisciplinary approach to osteoarthritis (OA) in older patients, whose functional decline is multifactorial and who present with multiple symptoms, has been long advocated, but it is still seldom implemented in daily practice. Therefore, further indications for the management of OA are eagerly awaited and should consider the specific clinical features of this population, including the presence of frailty and comorbidities. This clinical approach should be based both on well-grounded evidence and practical experience of experts in OA management. This manuscript comments the multidisciplinary integrated approach for OA management in the older population, according to the opinion of a multidisciplinary Panel of Experts. This project was developed by a Steering Committee, which consisted of three experts that were identified by the Italian Society of Physical and Rehabilitation Medicine (Società Italiana di Medicina Fisica e Riabilitativa, SIMFER) and the Italian Society for Unified and Interdisciplinary Management of Musculoskeletal Pain and Algodystrophy (Società Italiana per la Gestione Unificata e Interdisciplinare del Dolore muscolo-scheletrico e dell'Algodistrofia, SI-GUIDA). The Steering Committee identified key evidence on the management of OA in the older through systematic research in MEDLINE and EMBASE, selected the most relevant paper among those identified, and defined some questions concerning current unmet needs in the management of symptomatic OA in the older accordingly. The Panel discussed the identified evidence and questions during two meetings. The discussion was used to generate seven statements with relevance to clinical practice. In conclusion, older adults with symptomatic OA present multiple concomitant issues, including other diseases, marked pain, poly-pharmacy, and often poor psychological and/or socioeconomical status. According to the above-described evidence, it is crucial that the approach to those patients is multidisciplinary and based on the use of dedicated tools. A combination of exercise, mechanical support and properly selected analgesic treatment will greatly help the management of the OA patient, improving at the same time his/her quality of life.

Abstract
Background Osteoarthritis (OA) affects about 40% of people older than 40 years of age, and the mechanism is not well understood. Long non-coding RNA (lncRNA) CAIF is a recently identified critical player in myocardial infarction, while its role in other human diseases is unclear. The present study aimed to investigate the role of CAIF in OA. Material/Methods Levels of CAIF in synovial fluid of OA patients (n=60) and healthy controls (n=60) were measuring by performing quantitative real-time polymerase chain reaction (qRT-PCR). MiR-1246 and interleukin (IL)-6 levels in synovial fluid were measured by performing qRT-PCR and enzyme-linked immunosorbent assay (ELISA), respectively. Cell apoptosis analysis was performed after CHON-001 cells were treated with 500 mg/mL lipopolysaccharide (LPS) for 24 hours. Results We found that CAIF in synovial fluid was downregulated in OA patients and inversely correlated with miR-1246 and IL-6. Downregulated CAIF distinguished OA patients from healthy controls. In cells of chondrogenic cell line CHON-001, CAIF overexpression mediated the inhibited expression of miR-1246 and secretion of IL-6, while miR-1246 overexpression reduced the effects of CAIF overexpression on IL-6 secretion. In addition, CAIF overexpression inhibited the apoptosis of CHON-001 cells under LPS treatment, while miR-1246 overexpression attenuated the effects of CAIF overexpression. Conclusions Therefore, CAIF may downregulate miR-1246 to improve OA.

Intra-Articular Injection of Hydrolyzed Collagen to Treat Symptoms of Knee Osteoarthritis. A Functional In Vitro Investigation and a Pilot Retrospective Clinical Study. J Clin Med 2019; 8:jcm8070975. [PMID: 31277508 PMCID: PMC6678364 DOI: 10.3390/jcm8070975] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2019] [Revised: 06/27/2019] [Accepted: 07/03/2019] [Indexed: 12/19/2022] Open
Abstract
Among all joints affected, knee osteoarthritis has a prevalence of about 10% in men and 13% in women over 60 years old. Knee osteoarthritis has high economic and social costs and may have a devastating impact on patient quality of life. Treatment of symptomatic knee Osteoarthritis may involve oral or topical administration of non-steroidal anti-inflammatory drugs or intra-articular injection of corticosteroids. Recently, a novel injectable collagen formulation (ChondroGrid) consisting of bovine hydrolyzed <3 kDa type I collagen has been developed and is currently available on the market as an injectable medical device. The primary objective of this study was to investigate the in vitro and in vivo effects of ChondroGrid in treating knee osteoarthritis symptoms to assess its safety and performance. Viability and proliferation of ChondroGrid-exposed human chondrocytes derived from five donors were assessed through the Alamar Blue/CyQuant assays. Their expression of MMP1/MMP3 and TIMP1/TIMP3 was then assessed through RT-PCR and that of TGFβ1, IGF-I, and VEGF using ELISA assays. Shape and ECM deposition were assessed using the Bern score after a 28-day ChondroGrid exposure, and collagen deposition was assessed using immunostaining. Records of 20 patients affected by Kellgren Lawrence grade 1 to 4 knee osteoarthritis who received three 4 mg/2 mL ChondroGrid injections 2 weeks apart were then retrospectively assessed to compare VAS, Lequesne, and WOMAC scores collected before and 15, 45, and 225 days after the first injection. ChondroGrid had no effects on the markers under consideration, but induced type-II and inhibited type-I collagen deposition; the Bern score was higher when cells were cultured with ChondroGrid. Patients experienced a 44% Lequesne score and a 55% VAS at moving score reduction. All other scores decreased >70%. ChondroGrid may prompt chondrocytes to produce hyaline cartilage, prevent fibrous tissue formation, and be a safe and effective adjuvant to treat symptomatic knee osteoarthritis.

Combined intra-articular injection of corticosteroid and hyaluronic acid reduces pain compared to hyaluronic acid alone in the treatment of knee osteoarthritis. Knee Surg Sports Traumatol Arthrosc 2019; 27:1974-1983.

Abstract
PURPOSE Intra-articular injections of corticosteroid (CS) and hyaluronic acid (HA) have individually demonstrated efficacy for knee osteoarthritis (OA); however, both treatments are limited by the trajectory of symptom relief. The combination of CS and HA in the management of knee OA may provide improved symptomatic relief for patients who are candidates for intra-articular therapies. METHODS Electronic databases Medline, EMBASE and Cochrane Library were used to identify relevant publications. Randomized controlled trials (RCT) that evaluated intra-articular injections of combined CS and HA in comparison to HA alone were included. Outcomes eligible for meta-analysis were WOMAC pain, WOMAC total, OMERACT-OARSI responder rate, and treatment-related adverse events. Standardized mean differences (SMD) were calculated for continuous outcomes using an inverse variance method and a random-effects model. Odds ratios (OR) were calculated for dichotomous outcomes using the Mantel-Haenszel method and a random-effects model. Heterogeneity was assessed using the I2 statistic. RESULTS Eight trials (n = 751 patients) were included. Reduction in WOMAC pain scores at 2-4 weeks favoured the combined CS and HA group compared to HA alone [SMD 0.60, 95% CI (0.23, 0.97); p = 0.002, I2 = 75%]. Longer term improvements at 24-26 and 52 weeks WOMAC pain scores also favoured the combined CS and HA group {[SMD 0.25, 95% CI (0.09, 0.41); p = 0.002, I2 = 0%] and [SMD 0.39, 95% CI (0.01, 0.77); p = 0.05, I2 = 0%]} compared to HA alone, respectively. There were no significant differences in WOMAC total scores, OMERACT-OARSI responder rate, or treatment-related adverse events. CONCLUSION Combined intra-articular injections of CS and HA led to reductions in pain at 2-4, 24-26 and 52 weeks compared to HA injections alone. LEVEL OF EVIDENCE Level II-meta-analysis.

Abstract
Osteoarthritis (OA) is one of the most common chronic joint disease. Long non-coding RNAs (lncRNAs) have been confirmed to play important roles in a variety of diseases including OA. However, the underlying mechanism of lncRNA differentiation antagonizing non-protein coding RNA (DANCR) in OA has not been well elucidated. The expression of DANCR in cartilage tissues from OA patients was detected using quantitative real-time PCR. After cell transfection, the effects of DANCR inhibition on the proliferation, apoptosis and inflammatory factors of OA chondrocytes were detected using Cell Counting Kit-8 assay and flow cytometry assay. Novel target of DANCR was then identified through bioinformatics analysis and confirmed by luciferase reporter assay and RNA immunoprecipitation assay. The expression of DANCR was significantly increased in OA patients. Function assays demonstrated that DANCR suppression inhibited the proliferation, inflammation, and promoted apoptosis of chondrocytes cells. Additionally, DANCR regulated survival of OA chondrocytes through acting as a competitive endogenous RNA for miR-216a-5p. Furthermore, JAK2 was a direct target of miR-216a-5p, and DANCR regulated the JAK2/STAT3 signal pathway through miR-216a-5p in OA chondrocytes. In the present study, we concluded that DANCR promoted the proliferation, inflammation, and reduced cell apoptosis in OA chondrocytes through regulating miR-216a-5p/JAK2/STAT3 signaling pathway, indicating DANCR might be a useful biomarker and potential therapeutic target for OA treatment.

Abstract
Knee pain is one of the most common lower leg complaints. It is often treated with plantar orthoses to provide cushioning and correct locomotion, imbalances of the foot, and postural deficits. However, the published scientific data are poor concerning the mechanisms involved in pain reduction after wearing foot orthoses, and, to the best of our knowledge, no trial has investigated the mid-term effectiveness. The aim of the present study was to evaluate the effectiveness of foot orthoses according to sound biomechanical principles in the treatment of knee pain. Attention was mainly focused on changes in the central control strategies. Fifteen subjects were included in the protocol. The patients with knee pain were compared with healthy participants (control group) exhibiting no knee pain. In the patients with knee pain, pain perception, dynamic analysis of the gait, stabilometry, the soleus Hoffmann reflex at rest and during voluntary contraction, and V-wave were measured before and 3, 6, and 9 weeks after wearing orthoses. In the control group (n = 5), the same parameters were recorded at 0, 3, 6, and 9 weeks, but the subjects had not worn orthoses. In the patient group (n = 10), the results indicated that pain had significantly decreased from the third week onward, although the parameters of gait and stabilometry remained unchanged. From the sixth week, the soleus Hoffmann reflex during voluntary contraction wave was significantly reduced, suggesting an increase in motoneuronal presynaptic inhibition by non-nociceptive afferents. The V-wave amplitude increased throughout the 9 weeks of the experiment, suggesting a progressive increase in corticospinal and/or extrapyramidal descending pathway inputs, probably due to pain reduction. In the control group, no change was observed throughout the experimental sessions. Our data indicated that foot orthoses relieved patients' knee pain and reduced the descending motor inhibition. Changes in spinal modulation could contribute to a better quality of life. However, this treatment failed to change the altered gait, despite changes in spinal and supraspinal modulation.

Abstract
Methylene blue (MB) is a long-term inhibitor of peripheral nerve axons, thereby alleviating or permanently eliminating pain. However, it remains unknown whether MB is safe and effective method of treating osteoarthritis (OA). MB was injected into the knee joints of rabbits and they were monitored for any histological structural changes. The results revealed no evident changes in the histological structure of the normal knee joint following injection of 1 mg/kg MB at 1, 4, 8 and 24 weeks post-injection. Compared with the vehicle control, MB treatment significantly enhanced the weight distribution and significantly decreased the swelling ratio of the rabbits. Additionally, levels of long non-coding RNA (lncRNA) maternally expressed 3 (MEG3) mRNA were significantly increased following treatment with MB, but the protein expression of P2X purinoceptor 3 (P2X3) was significantly suppressed compared with the vehicle control. The levels of interleukin (IL) 6, tumor necrosis factor (TNF)α, IL-1β and IL-8 were significantly suppressed following MB treatment, indicating that MB protects against OA progression. It was also revealed that MEG3 overexpression significantly suppresses levels of P2X3 protein. ELISA indicated that the MEG3-induced reduction of IL-6, TNFα, IL-1β and IL-8 expression was significantly reversed following P2X3 overexpression. Therefore, the results of the present study demonstrated that MB is an effective method of treating OA-associated pain by upregulating lncRNA MEG3 levels. Additionally, lncRNA MEG3 relieves the OA-associated pain and inflammation in a rabbit model of OA by inhibiting P2X3 expression.

Abstract
Long noncoding RNAs (lncRNAs) have been known to be involved in multiple diverse diseases, including osteoarthritis (OA). The present study aims at exploring the biological role of lncRNA plasmacytoma variant translocation 1 (PVT1) in OA and the underlying mechanism. Results showed that the expression of PVT1 was upregulated in OA chondrocytes compared with normal chondrocytes, silencing PVT1 inhibited the apoptosis of OA chondrocytes, and overexpression of PVT1 promoted the apoptosis of normal chondrocytes. To further investigate the underlying mechanism, miR-488-3p was predicted to be a targeted microRNA of PVT1. Different methods, including MS2 RNA immunoprecipitation (RIP), luciferase activity, and anti-AGO2 RIP, were performed to detect the interaction between PVT1 and miR-488-3p, which suggested that PVT1 negatively regulated miR-488-3p in OA chondrocytes. Moreover, PVT1 promoted the apoptosis of OA and normal chondrocytes through miR-488-3p. Collectively, this study revealed that lncRNA PVT1 regulated the apoptosis of chondrocytes by acting as a sponge for miR-488-3p in OA. PVT1 may be considered a new therapeutic target for the treatment of OA.
