BACKGROUND:Research has shown that vanillic acid has anti-inflammatory and anti-oxidative stress effects,but it is unclear whether it has a protective effect on endplate chondrocytes.OBJECTIVE:To explore the effect and mechanism of vanillic acid on endplate chondrocytes under inflammatory microenvironment.METHODS:(1)Primary endplate chondrocytes were isolated from the intervertebral disc of SD rats and identified by toluidine blue staining and collagenⅡ immunofluorescence.(2)The CCK-8 assay was employed to detect the effects of interleukin-1β and vanillic acid on the proliferation activity of endplate chondrocytes,in order to determine the concentration of vanillic acid for subsequent cell treatment.(3)An inflammatory microenvironment was simulated by adding 10 ng/mL interleukin-1β to the culture medium,and the endplate chondrocytes were treated with low,medium,and high mass concentrations of vanillic acid.The expression levels of inflammatory markers and extracellular matrix proteins were detected by western blot assay and immunofluorescence.(4)The expression of nuclear factor κB signaling pathway-related proteins was detected by western blot assay.RESULTS AND CONCLUSION:(1)The morphology of endplate chondrocytes in adherent culture was pike or triangular in shape,positive for toluidine blue staining and immunofluorescence for collagen Ⅱ,indicating that the experimentally extracted cells were endplate chondrocytes.(2)The CCK-8 assay results showed that treatment with 2.5,5,10,and 20 μg/mL vanillic acid for 24 hours did not significantly inhibit the proliferation of endplate chondrocytes.Compared with the interleukin-1β group,the viability of endplate chondrocytes treated with 5,10,and 20 μg/mL vanillic acid for 24 hours was significantly increased(P<0.05).Therefore,5,10,and 20 μg/mL vanillic acid was selected as the low,medium,and high dose groups for subsequent treatment of endplate chondrocytes.(3)Compared with the model group(complete medium containing 10 ng/mL interleukin-1β),the expression of NOD-like receptor thermal domain associated protein 3(NLRP3),matrix metalloproteinase 13,matrix metalloproteinase 3,and tumor necrosis factor alpha protein in the endplate chondrocytes of the low,medium,and high doses of vanillic acid groups were significantly reduced(P<0.05).(4)Compared with the model group,the protein expression of aggrecan and collagen Ⅱ in the endplate chondrocytes of the low,medium,and high dose groups of vanillic acid significantly increased(P<0.05).(5)Compared with the model group,the protein expression of phospho-nuclear factor κB and phospho-inhibitor of nuclear factor κB in the endplate chondrocytes of the low,medium,and high dose groups of vanillic acid was significantly reduced(P<0.05).(6)The above results indicate that vanillic acid may alleviate the inflammatory response and extracellular matrix degradation induced by interleukin-1β in rat endplate chondrocytes by inhibiting the activation of the nuclear factor κB signaling pathway.

AIM:To compare the effect of AT TORBI 709M and Tecnis ZMT intraocular lenses on astigmatism correction in patients with corneal astigmatism at 3 mo after operation based on the standard astigmatism vector analysis.METHODS: This was a retrospective case-control study. The clinical data of 69 patients(69 eyes)with corneal astigmatism who underwent phacoemulsification and implantation of toric intraocular lens(IOL)from June 2021 to December 2021 in Day Surgery Center of Xi'an No.1 Hospital was analyzed. The patients were divided into two groups. In group one, 38 cases(38 eyes)were implanted with AT TORBI 709M, and 31 patients(31 eyes)with Tecnis ZMT in group two. The axial length, preoperative astigmatism and axis, and the degree of intraocular lens were recorded. The uncorrected distance visual acuity(UCDVA), best corrected distance visual acuity(BCDVA), diopter, residual astigmatism and axis were recorded preoperatively and at 1 wk, 1 and 3 mo postoperatively. The postoperative surgical indicators, including spherical equivalent(SE), target induced astigmatism vector(TIA), surgically induced astigmatism vector(SIA), magnitude of error(ME), absolute value of angle of error(|AE|), absolute value of difference vector(|DV|), correction index(CI), and index of success(IOS)were evaluated by the standard astigmatism vector analysis.RESULTS:Postoperative UCDVA and BCDVA were significantly improved(all P<0.001), and there were statistically significant differences compared to preoperative UCDVA and BCDVA(all P<0.001). While, there was no significant difference in UCDVA and BCDVA between the two groups(P=0.275, 0.124). The standard astigmatism vector analysis showed that a good astigmatism correction was achieved in both AT TORBI 709M group and Tecnis ZMT group, and both |DV| and IOS were close to 0(P=0.329, 0.288). The CI of the AT TORBI 709M group was closer to 1, indicating a better astigmatism correction, while the CI of the Tecnis ZMT group was higher than 1, suggesting an overcorrection of astigmatism. However, the difference between the two groups was not statistically significant(P=0.193). The mean residual astigmatism at 3 mo postoperatively was -0.11±0.91 D in the AT TORBI 709M group and -0.46±0.76 D in the Tecnis ZMT group, respectively, showing no statistically significance difference(t=1.732, P=0.088).CONCLUSION:Both the flat loop AT TORBI 709M and the double C-loop Tecnis ZMT intraocular lenses can effectively improve postoperative visual acuity in patients with regular corneal astigmatism, showing good rotational stability and comparable correction abilities for both astigmatism with the rule and against-the-rule astigmatism.

G protein-coupled receptor kinase 2 (GRK2) participates in the phosphorylation and desensitization of G protein-coupled receptor (GPCR), impacting various biological processes such as inflammation and cell proliferation. Dysregulated expression and activity of GRK2 have been reported in multiple cells in rheumatoid arthritis (RA). However, whether and how GRK2 regulates synovial hyperplasia and fibroblast-like synoviocytes (FLSs) proliferation is poorly understood. In this study, we investigated the regulation of GRK2 and its biological function in RA. We found that GRK2 transmembrane activity was increased in FLSs of RA patients and collagen-induced arthritis (CIA) rats. Additionally, we noted a positive correlation between high GRK2 expression on the cell membrane and serological markers associated with RA and CIA. Immunoprecipitation-mass spectrometry and pull-down analyses revealed tumor necrosis factor receptor-associated factor 2 (TRAF2) as a novel substrate of GRK2. Furthermore, surface plasmon resonance (SPR) and molecular docking assays determined that the C-terminus of GRK2 binds to the C-terminus of TRAF2 at the Gln340 residue. GRK2 knockdown and the GRK2 inhibitor CP-25 attenuated synovial hyperplasia and FLS proliferation in CIA both in vitro and in vivo by decreasing GRK2 membrane expression and activity. Mechanistically, increased GRK2 transmembrane activity contributed to the recruitment of TRAF2 on the cell membrane, promoting GRK2-TRAF2 interactions that facilitate the recruitment of the E3 ubiquitin ligase TRIM47 to TRAF2. This enhanced TRAF2 Lys63 polyubiquitylation and induced nuclear factor (NF)-κB activation, leading to synovial hyperplasia and abnormal proliferation of FLSs. Our study provides a mechanistic and preclinical rationale for further evaluation of GRK2 as a therapeutic target for RA.

OBJECTIVE To investigate the effects and mechanism of Yiqi huoxue decoction (YQHX) on lumbar disc herniation in rats. METHODS Rats were randomly divided into sham operation group, model group, NF-κB inhibitor group (QNZ group, 1 mg/kg), YQHX group (9.1 g/kg) and combination group (YQHX+QNZ group, the same dose as each single drug group), with 10 rats in each group. Except for sham operation group, lumbar disc herniation model of rats was induced in other groups; administration groups were given QNZ intraperitoneally or/and YQHX intragastrically, once a day, for 8 consecutive weeks. The severity of intervertebral disc herniation was evaluated in each group; the pathological changes of intervertebral discs and the changes of autophagy of nucleus pulposus cells were all observed; the level of tumor necrosis factor-α (TNF-α) in serum, and the ratios of Bcl-2/adenovirus E1B interacting protein 3 (BNIP3) and Beclin-1 positive cells in intervertebral disctissues were detected; the phosphorylation of nuclear factor-κB (NF-κB) p65, the expressions of tumor necrosis factor receptor- associated factor-2 (TRAF-2), TRAF-3, BNIP3 and LC3B protein, and mRNA expressions of NF-κB p65, LC3B, p62,BNIP3 and Beclin-1 were determined. RESULTS Compared with model group, Pfirrmann grading score decreased significantly,the pathological injury of intervertebral disc tissue was relieved in YQHX group; the number of autophagosomes in nucleus pulposus cells increased; serum level of TNF-α and mRNA expression of p62 in intervertebral disc tissue decreased significantly; the ratios of BNIP3 and Beclin-1 positive cells, the phosphorylation of NF-κB p65, the expressions of TRAF-2, TRAF-3, BNIP3 and LC3B protein as well as the mRNA expressions of NF- κB p65, LC3B, BNIP3 and Beclin-1 decreased significantly in intervertebral disc tissues (P<0.05). The changes of above indexes in YQHX group were reversed partly in YQHX+QNZ group. CONCLUSIONS YQHX promotes the elevation of autophagy level of intervertebral discs, slows down the inflammatory response and the progression of lumbar disc herniation by activating the NF-κB signaling pathway.
