OBJECTIVE: To investigate the effects and underlying mechanisms of VX765 on osteoarthritis (OA) and chondrocytes inflammation in rats. METHODS: Chondrocytes were isolated from the knee joints of 4-week-old Sprague Dawley (SD) rats. The third-generation cells were subjected to cell counting kit 8 (CCK-8) analysis to assess the impact of various concentrations (0, 1, 5, 10, 20, 50, 100 μmol/L) of VX765 on rat chondrocyte activity. An in vitro lipopolysaccharide (LPS) induced cell inflammation model was employed, dividing cells into control group, LPS group, VX765 concentration 1 group and VX765 concentration 2 group without obvious cytotoxicity. Western blot, real-time fluorescence quantitative PCR, and ELISA were conducted to measure the expression levels of inflammatory factors-transforming growth factor β ₁ (TGF-β ₁), interleukin 6 (IL-6), and tumor necrosis factor α (TNF-α). Additionally, Western blot and immunofluorescence staining were employed to assess the expressions of nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase 1 (HO-1). Thirty-two SD rats were randomly assigned to sham surgery group (group A), OA group (group B), OA+VX765 (50 mg/kg) group (group C), and OA+VX765 (100 mg/kg) group (group D), with 8 rats in each group. Group A underwent a sham operation with a medial incision, while groups B to D underwent additional transverse incisions to the medial collateral ligament and anterior cruciate ligament, with removal of the medial meniscus. One week post-surgery, groups C and D were orally administered 50 mg/kg and 100 mg/kg VX765, respectively, while groups A and B received an equivalent volume of saline. Histopathological examination using HE and safranin-fast green staining was performed, and Mankin scoring was utilized for evaluation. Immunohistochemical staining technique was employed to analyze the expressions of matrix metalloproteinase 13 (MMP-13) and collagen type Ⅱ. RESULTS: The CCK-8 assay indicated a significant decrease in cell viability at VX765 concentrations exceeding 10 μmol/L ( P<0.05), so 4 μmol/L and 8 μmol/L VX765 without obvious cytotoxicity were selected for subsequent experiments. Following LPS induction, the expressions of TGF-β ₁, IL-6, and TNF-α in cells significantly increased when compared with the control group ( P<0.05). However, intervention with 4 μmol/L and 8 μmol/L VX765 led to a significant decrease in expression compared to the LPS group ( P<0.05). Western blot and immunofluorescence staining demonstrated a significant upregulation of Nrf2 pathway-related molecules Nrf2 and HO-1 protein expressions by VX765 ( P<0.05), indicating Nrf2 pathway activation. Histopathological examination of rat knee joint tissues and immunohistochemical staining revealed that, compared to group B, treatment with VX765 in groups C and D improved joint structural damage in rat OA, alleviated inflammatory reactions, downregulated MMP-13 expression, and increased collagen type Ⅱ expression. CONCLUSION VX765 can improve rat OA and reduce chondrocyte inflammation, possibly through the activation of the Nrf2 pathway.

OBJECTIVE: To prepare a novel hyaluronic acid methacrylate (HAMA) hydrogel microspheres loaded polyhedral oligomeric silsesquioxane-diclofenac sodium (POSS-DS) patricles, then investigate its physicochemical characteristics and in vitro and in vivo biological properties. METHODS: Using sulfhydryl POSS (POSS-SH) as a nano-construction platform, polyethylene glycol and DS were chemically linked through the "click chemistry" method to construct functional nanoparticle POSS-DS. The composition was analyzed by nuclear magnetic resonance spectroscopy and the morphology was characterized by transmission electron microscopy. In order to achieve drug sustained release, POSS-DS was encapsulated in HAMA, and hybrid hydrogel microspheres were prepared by microfluidic technology, namely HAMA@POSS-DS. The morphology of the hybrid hydrogel microspheres was characterized by optical microscope and scanning electron microscope. The in vitro degradation and drug release efficiency were observed. Cell counting kit 8 (CCK-8) and live/dead staining were used to detect the effect on chondrocyte proliferation. Moreover, a chondrocyte inflammation model was constructed and cultured with HAMA@POSS-DS. The relevant inflammatory indicators, including collagen type Ⅱ, aggrecan (AGG), matrix metalloproteinase 13 (MMP-13), recombinant A disintegrin and metalloproteinase with thrombospondin 5 (Adamts5), and recombinant tachykinin precursor 1 (TAC1) were detected by immunofluorescence staining and real-time fluorescence quantitative PCR, with normal cultured chondrocytes and the chondrocyte inflammation model without treatment as control group and blank group respectively to further evaluate their anti-inflammatory activity. Finally, by constructing a rat model of knee osteoarthritis, the effectiveness of HAMA@POSS-DS on osteoarthritis was evaluated by X-ray film and Micro-CT examination. RESULTS: The overall particle size of POSS-DS nanoparticles was uniform with a diameter of about 100 nm. HAMA@POSS-DS hydrogel microspheres were opaque spheres with a diameter of about 100 μm and a spherical porous structure. The degradation period was 9 weeks, during which the loaded POSS-DS nanoparticles were slowly released. CCK-8 and live/dead staining showed no obvious cytotoxicity at HAMA@POSS-DS, and POSS-DS released by HAMA@POSS-DS significantly promoted cell proliferation (P<0.05). In the chondrocyte anti-inflammatory experiment, the relative expression of collagen type Ⅱ mRNA in HAMA@POSS-DS group was significantly higher than that in control group and blank group (P<0.05). The relative expression level of AGG mRNA was significantly higher than that of blank group (P<0.05). The relative expressions of MMP-13, Adamts5, and TAC1 mRNA in HAMA@POSS-DS group were significantly lower than those in blank group (P<0.05). In vivo experiments showed that the joint space width decreased after operation in rats with osteoarthritis, but HAMA@POSS-DS delayed the process of joint space narrowing and significantly improved the periarticular osteophytosis (P<0.05). CONCLUSION HAMA@POSS-DS can effectively regulate the local inflammatory microenvironment and significantly promote chondrocyte proliferation, which is conducive to promoting cartilage regeneration and repair in osteoarthritis.

BACKGROUND: Clinical trial evidence is limited to identify better topical non-steroidal anti-inflammatory drugs (NSAIDs) for treating knee osteoarthritis (OA). We aimed to compare the clinical efficacy and safety of flurbiprofen cataplasms (FPC) with loxoprofen sodium cataplasms (LSC) in treating patients with knee OA. METHODS: This is an open-label, non-inferiority randomized controlled trial conducted at Peking University Shougang Hospital. Overall, 250 patients with knee OA admitted from October 2021 to April 2022 were randomly assigned to FPC and LSC treatment groups in a 1:1 ratio. Both medications were administered to patients for 28 days. The primary outcome was the change of pain measured by visual analog scale (VAS) score from baseline to day 28 (range, 0-10 points; higher score indicates worse pain; non-inferiority margin: 1 point; superiority margin: 0 point). There were four secondary outcomes, including the extent of pain relief, the change trends of VAS scores, joint function scores measured by the Western Ontario and McMaster University Osteoarthritis Index (WOMAC), and adverse events. RESULTS: Among 250 randomized patients (One patient without complete baseline record in the flurbiprofen cataplasms was excluded; age, 62.8 ± 10.5 years; 61.4% [153/249] women), 234 (93.6%) finally completed the trial. In the intention-to-treat analysis, the decline of the VAS score for the 24-h most intense pain in the FPC group was non-inferior, and also superior to that in the LSC group (differences and 95% confidence interval, 0.414 (0.147-0.681); P <0.001 for non-inferiority; P = 0.001 for superiority). Similar results were observed of the VAS scores for the current pain and pain during exercise. WOMAC scores were also lower in the FPC group at week 4 (12.50 [8.00-22.50] vs . 16.00 [11.00-27.00], P = 0.010), mainly driven by the dimension of daily activity difficulty. In addition, the FPC group experienced a significantly lower incidence of adverse events (5.6% [7/124] vs . 33.6% [42/125], P <0.001), including irritation, rash and pain of the skin, and sticky hair uncovering pain. CONCLUSIONS This study suggested that FPC is superior to LSC for treating patients with knee OA in pain relief, joint function improvement, and safety profile.

OBJECTIVE: To investigate the effect of indirubin for relieving joint inflammation and injury in a rat model of osteoarthritis. METHODS: Articular cartilage chondrocytes were isolated from adult rat knee joint and cultured in the presence of interleukin-1β (IL-1β) and 0.1, 0.5, 1.0, or 2.0 μmol/L indirubin. The cells were transfected with NPAS2 siRNA or a non-specific siRNA, and the cell proliferation and apoptosis were evaluated using tetramethylthiazole blue staining and flow cytometry. The protein expression levels of Bax, Bcl-2, ACAN, COL2A1, MMP-13 and NPAS2 were detected with Western blotting, and the levels of NO, PGE2 and TNF-α in the culture supernatant were determined with ELISA. The mRNA expression levels of NPAS2, ACAN, COL2A1 and MMP-13 were detected using fluorescence quantitative PCR. In a C57BL/6 mouse model of osteoarthritis, the effect of indirubin on BAX, Bcl-2, ACAN and MMP-13 protein expressions in the bone and joint tissues were evaluated with Western blotting. RESULTS: Treatment with 0.1 μmol/L indirubin produced no significant changes in chondrocyte proliferation, apoptosis, caspase-3 activity, or BAX and Bcl-2 protein expressions. At higher doses (0.5, 1.0 and 2.0 μmol/L), indirubin significantly promoted cell proliferation, increased Bcl-2 protein expression, and lowered cell apoptosis rate, caspase-3 activity and Bax protein expression (P < 0.05). Indirubin treatment at 0.5 μmol/L up-regulated the protein and mRNA expressions of NPAS2, ACAN and COL2A1, and down-regulated the expressions of MMP-13, NO, PGE2 and TNF-α (P < 0.05). Interference of NPAS2 expression significantly attenuated the protective effect of 0.5 μmol/L indirubin against IL-1β-induced chondrocyte injury. The mouse model of osteoarthritis showed obviously increased protein levels of BAX and MMP-13 (P < 0.01) and decreased levels of Bcl-2 (P < 0.05) and ACAN (P < 0.01) in the knee joint, and indirubin treatment of the mouse models significantly inhibited the increase of BAX and MMP-13 protein expressions (P < 0.01) and up-regulated the protein expressions of Bcl-2 and ACAN (P < 0.05). CONCLUSION Indirubin has a protective effect on osteoarthritis tissue and alleviates inflammation and damage of osteoarthritis chondrocytes possibly through NPAS2.

Osteoarthritis is a common disease characterized by degenerative lesions of articular cartilage in the elderly.Fufang Duzhong Jiangu Granulues(FDJG), a classical prescription for the treatment of osteoarthritis, has the effects of nourishing liver and kidney, nourishing blood and sinew, and dredging collaterals and relieving pain.In this study, molecular simulation technology was combined with molecular biology methods to explore and verify the potential pharmacodynamic substances and molecular mechanism of FDJG in the treatment of osteoarthritis.Arachidonic acid(AA) metabolic pathway is a typical anti-inflammatory pathway, and secretory phospholipase A2 group ⅡA(sPLA2-ⅡA), 5-lipoxygenase(5-LOX), cyclooxygenase-2(COX-2), and leukotriene A4 hydrolase(LTA4 H) are the key targets of the pathway.Therefore, in this study, based on the pharmacophores and molecular docking models of the four key targets in AA pathway, a total of 1 522 chemical components in 12 medicinals of FDJG were virtually screened, followed by weighted analysis of the screening results in combination with the proportions of the medicinals in the prescription.The results showed that mainly 73 components in the preparation could act on the above four targets, suggesting they might be the potential anti-osteoarthritis components of FDJG.Considering the predicted effectiveness, availability, and compatibility of the medicinals, coniferyl ferulate, olivil, and baicalin were selected for further verification.Specifically, lipopolysaccharide(LPS)-induced RAW264.7 inflammatory cell model was used to verify the anti-inflammatory activity of the three components.The results showed that the three can effectively inhibit the release of NO, supporting the above selection.In addition, targets 5-LOX, COX-2, and LTA4 H had high activity, which suggested that they may be the key anti-osteoarthritis targets of FDJG.The comprehensive activity values of Eucommiae Cortex, Achyranthis Bidentatae Radix, Ginseng Radix et Rhizoma, Lycii Fructus, and Astragali Radix were much higher than that of other medicinals in the prescription, indicating that they may be the main effective medicinals in FDJG acting on the AA pathway.In this study, the potential anti-osteoarthritis components of FDJG were obtained.Moreover, it was clarified that the anti-osteoarthritis mechanism of FDJG was to act on LOX and COX pathway in AA metabolic pathway, which provided a reference for the study of pharmacodynamic substances and molecular mechanism of FDJG.

This study aims to investigate the therapeutic effects of alkaloids in Tibetan medicine Bangna(Aconiti Penduli et Aconiti Flavi Radix) on osteoarthritis(OA) rats in vitro and in vivo and the underlying mechanisms. Chondrocytes were isolated from 2-3 week-old male SD rats and lipopolysaccharide(LPS) was used to induce OA in chondrocytes in vitro. Methyl thiazolyl tetrazolium(MTT) assay was used to investigate the toxicity of seven alkaloids(12-epi-napelline, songorine, benzoylaconine, aconitine, 3-acetylaconitine, mesaconitine, and benzoylmesaconine) to chondrocytes. Chondrocytes were classified into the control group, model group(induced by LPS 5 μg·mL~(-1) for 12 h), and administration groups(induced by LPS 5 μg·mL~(-1) for 12 h and incubated for 24 h). The protein expression of inflammatory factors cyclooxygenase-2(COX-2), inducible nitric oxide synthetase(iNOS), tumor necrosis factor-α(TNF-α), and interleukin-1β(IL-1β) in each group were detected by Western blot, and the protein expression of matrix metalloprotease-13(MMP-13), aggrecan, collagen Ⅱ, fibroblast growth factor 2(FGF2) by immunofluorescence staining. For the in vivo experiment, sodium iodoacetate was used to induce OA in rats, and the expression of MMP-13, TNF-α, and FGF2 in cartilage tissues of rats in each group was detected by immunohistochemistry. The results showed that the viability of chondrocytes could reach more than 90% under the treatment of the seven alkaloids in a certain dose range. Aconitine, 12-epi-napelline, songorine, 3-acetylaconitine, and mesaconitine could decrease the protein expression of inflammatory factors COX-2, iNOS, TNF-α and IL-1β compared with the model group. Moreover, 12-epi-napelline, aconitine, and mesaconitine could down-regulate the expression of MMP-13 and up-regulate the expression of aggrecan and collagen Ⅱ. In addition, compared with the model group and other Bangna alkaloids, 12-epi-napelline significantly up-regulated the expression of FGF2. Therefore, 12-epi-napelline was selected for the animal experiment in vivo. Immunohistochemistry results showed that 12-epi-napelline could significantly reduce the expression of MMP-13 and TNF-α in cartilage tissues, and up-regulate the expression of FGF2 compared with the model group. In conclusion, among the seven Bangna alkaloids, 12-epi-napelline can promote the repair of OA in rats by down-regulating the expression of MMP-13 and TNF-α and up-regulating the expression of FGF2.

Metabolomics based on ultra-high performance liquid chromatography-tandem quadrupole time-of-flight mass spectrometry(UHPLC-Q-TOF-MS) was employed to analyze the effect of Cyathulae Radix on serum and urine in rats with knee osteoarthritis, and to decipher the mechanism of Cyathulae Radix in the treatment of knee osteoarthritis. SD rats were randomized into a normal group, a model group, a positive drug group, and a Cyathulae Radix group. The knee osteoarthritis model was established by injecting 2% pa-pain and 0.03 mol·L~(-1) cysteine, and the serum levels of tumor necrosis factor-α(TNF-α) and matrix metalloproteinase-3(MMP-3) in the model group was measured to preliminarily evaluate the therapeutic effect of Cyathulae Radix on knee osteoarthritis. UHPLC-Q-TOF-MS was employed to establish the metabolic profile of endogenous small molecule metabolites in the four groups. Potential biomarkers were screened out by multivariate analysis methods such as partial least squares discriminant analysis(PLS-DA) and orthogonal partial least squares discriminant analysis(OPLS-DA) in combination with t-test, variable importance for projection(VIP), and fold-change. The related metabolic pathways were enriched with the help of MetaboAnalyst 5.0. The results showed that Cyathulae Radix alleviated the general signs of rats with knee osteoarthritis, and reduced the levels of TNF-α and MMP-3 in the rat serum. Twenty-eight differential metabolites that might be associated with the therapeutic effect of Cyathulae Radix were screened out from serum and urine. They were mainly involved in arginine biosynthesis, nicotinate and nicotinamide metabolism, tricarboxylic acid cycle, alanine, aspartate and glutamate metabolism, riboflavin metabolism, glyoxylate and dicarboxylate metabolism, and pyrimidine metabolism. Through metabonomics analysis, this study predicted the possible mechanism of Cyathulae Radix in the treatment of knee osteoarthritis, which laid a foundation for further research.

This study aims to assess the efficacy and safety of Hulisan Capsules in the treatment of knee osteoarthritis, which is expected to serve as a reference for clinical practice. To be specific, randomized controlled trial(RCT) on the treatment of knee osteoarthritis with Hulisan Capsules was retrieved from EMbase, PubMed, Cochrane Library, Web of Science, CNKI, Wanfang, SinoMed, and VIP(from inception to November 15, 2021). Two researchers independently screened the articles, extracted the data, and evaluated the risk of bias with ROB. RevMan 5.4 was used for Meta-analysis. Finally, 12 RCTs were screened out, involving 1 703 cases(1 075 in the experimental group and 628 in the control group). Meta-analysis showed that conventional treatment + Hulisan Capsules was superior to conventional treatment alone in terms of symptom relief rate(RR=1.19, 95%CI[1.09, 1.30], P<0.000 1), Lysholm score(MD=11.17, 95%CI[7.35, 15.00], P<0.000 01), visual analogue scale(VAS) score(MD=-0.99, 95%CI[-1.30,-0.68], P<0.000 01), and knee function score(RR=8.94, 95%CI[6.51, 11.37], P<0.000 01). Hulisan Capsules alone was superior to the conventional treatment alone in terms of the symptom relief rate(RR=1.38, 95%CI[1.13, 1.69], P=0.002) and knee function score(MD=2.88, 95%CI[0.81, 4.94], P=0.006), but VAS score was insignificantly different between the patients treated with Hulisan Capsules alone and those with conventional treatment alone(MD=-0.57, 95%CI[-1.42, 0.29], P=0.19). Hulisan Capsules + conventional treatment showed insignificant difference in symptom relief rate from the Zhuifeng Tougu Capsules + conventional treatment(RR=1.07, 95%CI[0.91, 1.25], P=0.44). The Lequesne score was insignificantly different between Hulisan Capsules + conventional treatment and conventional treatment/Zhuifeng Tougu Capsules + conventional treatment(MD=-2.17, 95%CI[-6.29, 1.96], P=0.30). The incidence of adverse reactions in the experimental group was significantly lower than control group(RR=0.57, 95%CI[0.34, 0.96], P=0.03). According to the available data and methods, Hulisan Capsules/Hulisan Capsules + conventional treatment could improve the symptom relief rate, Lysholm score, knee function score, and VAS score of patients with knee osteoarthritis, and alleviate the symptoms of pain, stiffness, and swelling of them. No serious adverse reactions were found yet. In the future, more large-sample and standard clinical trials are needed to verify the effect and safety of Hulisan Capsules in the treatment of knee osteoarthritis.

OBJECTIVE: To explore effects of acupotomy on pain, function, gait and serum inflammatory factors in patients with knee osteoarthritis(KOA). METHODS: From December 2017 to June 2019, 110 patients with KOA were collected and divided into acupotomy group(56 cases) and western medicine group(54 cases) by using random number table method. In acupotomy group, there were 16 males and 40 females, aged from 46 to 74 years old with an average of (62.98±6.68) years old, the course of disease ranged from 1 to 240 months with an average of 24.5(15.25, 33.00) months;were treated with acupotomy on the pain points around knee joint once a week for 3 weeks. In western medicine group, there were 18 males and 36 females, aged from 47 to 73 years old with an average of (64.19±5.98 ) years old;the course of disease ranged from 1 to 220 months with an average of 25.00(13.75, 33.00) months;were took celecoxib capsule orally, 200 mg once a day for 3 weeks. Oxford Knee Score(OKS) was performed before treatment, 3 weeks and 3 months after treatment. Gait kinematics analysis and serum levels of tumor necrosis factor-α(TNF-α) and interleukin-1β (IL-1β) were measured before and after treatment for 3 weeks. RESULTS: All patients were followed up from 6 to 24 months with an average of(15.03±4.55) months. OKS between two groups decreased significantly at 3 weeks and 3 months after treatment(P<0.001). Functional scores and overall scores in acupotomology group were significantly decreased at 3 months compared with 3 weeks after treatment(P<0.001). OKS of acupotomy group were significantly lower than those of western medicine group at 3 weeks and 3 months after treatment(P<0.05). Gait speed, frequency and length between two groups were significantly improved at 3 weeks after treatment(P<0.05). At 3 weeks after treatment, gait freguency of acupotomy group was significantly improved compared with western medicine group(P<0.05). TNF-α and IL-1β were significantly lower in both groups at 3 weeks after treatment than before treatment(P<0.05). At 3 weeks after treatment, level of IL-1 β was lower in western medicine group than in acupotomy group(P<0.05), and difference in TNF-α level was not statistically significant(P>0.05). CONCLUSION Acupotomology of pain points could significantly improve pain, function, gait, and decreased serum inflammatory factors at early to mid stage of KOA patients, in particular, it is superior to non-steroidal anti-inflammatory drugs in terms of knee function recovery and cadence improvement.
