Objective:To investigate the effect of fibulin-3 on the senescence of intervertebral disc nucleus pulposus cells (NPCs) through the regulation of tissue inhibitor of metalloproteinases 3 (TIMP-3) expression and to elucidate the molecular mechanisms involved. Methods:1). The nucleus pulposus tissues and imaging data of 37 patients who had undergone intervertebral disc surgery were collected. The degree of degeneration of the intervertebral discs were classified according to the Pfirrmann grading system. The senescence degree of NPCs was determined using senescence-associated β-galactosidase (SA-β-gal) staining. Fibulin-3 expression levels were determined using Western blot and ELISA. The relationship between fibulin-3 and disc degeneration and NPCs senescence was investigated. 2). Human intervertebral disc NPCs were cultured in vitro. The proliferation and senescence of NPC across continuous passage were observed via CCK-8 assay and SA-β-gal staining, respectively. Fibulin-3 expression levels and the expression of inflammatory cytokines and matrix metalloproteinases were assessed. Exogenous fibulin-3 was added to verify its effect on the proliferation and senescence of NPCs. 3). The effect of fibulin-3 on the apoptosis and proliferation of NPCs was verified through gene overexpression, which was used in combination with an apoptosis inhibitor for bidirectional verification. 4). Bioinformatics analysis was performed to explore the relationship between fibulin-3 and the TIMP family. Experiments overexpressing fibulin-3 and silencing the TIMP-3 gene were performed to verify their role in NPCs senescence. Results:1). The intervertebral disc degeneration samples from 37 patients were classified according to the Pfirrmann grading system. The higher the degeneration grade, the lower fibulin-3 expression. Spearman correlation analysis showed that the disc grade was negatively correlated with the NPC senescence grade (r=-0.87, P<0.001) and fibulin-3 expression (r=-0.79, P<0.001). 2). As the passage number of NPCs increased, fibulin-3 expression gradually decreased, cell proliferation ability weakened, and the expression of inflammatory cytokines and matrix metalloproteinases increased. After exogenous fibulin-3 was added, cell morphology and growth status were maintained, cell senescence was significantly inhibited, and the expression of inflammatory cytokines and matrix metalloproteinases was markedly reduced. 3). Gene overexpression experiments showed that fibulin-3 reduced NPC apoptosis and promoted cell proliferation, thereby inhibiting NPC senescence. 4). Bioinformatics analysis revealed a significant association between fibulin-3 and TIMP-3 of the TIMP family. Further experiments confirmed that overexpressing fibulin-3 enhanced TIMP-3 expression, while silencing the TIMP-3 gene significantly weakened the inhibitory effect of fibulin-3 on NPCs senescence. This indicates that, through regulating TIMP-3, fibulin-3 inhibits the activity of matrix metalloproteinases, affects the synthesis and degradation of the extracellular matrix, and ultimately inhibits NPCs senescence. Conclusion:This study demonstrates that fibulin-3 plays a crucial role in inhibiting the senescence of intervertebral disc NPCs by regulating TIMP-3. The specific mechanisms involved are as follows, fibulin-3 upregulates TIMP-3 expression, inhibits matrix metalloproteinase activity, and reduces extracellular matrix degradation, thereby promoting extracellular matrix synthesis. Additionally, fibulin-3 inhibits NPCs senescence by reducing apoptosis and promoting cell proliferation. Therefore, fibulin-3 and TIMP-3 have potential therapeutic significance in maintaining intervertebral disc health and delaying degeneration.
Objective:To explore the feasibility and accuracy of ultrasound volume navigation (UVN) combined with X-ray fluoroscopy-guided percutaneous pedicle screw implantation through a prospective randomized controlled study. Methods:Patients with thoracic and lumbar vertebral fractures scheduled for percutaneous pedicle screw fixation between January 2022 and January 2023 were enrolled. Among them, 60 patients met the selection criteria and were included in the study. There were 28 males and 32 females, with an average age of 49.5 years (range, 29-60 years). The cause of injury included 20 cases of traffic accidents, 21 cases of falls, 17 cases of slips, and 2 cases of heavy object impact. The interval from injury to hospital admission ranged from 1 to 5 days (mean, 1.57 days). The fracture located at T 12 in 15 cases, L 1 in 20 cases, L 2 in 19 cases, and L 3 in 6 cases. The study used each patient as their own control, randomly guiding pedicle screw implantation using UVN combined with X-ray fluoroscopy on one side of the vertebral body and the adjacent segment (trial group), while the other side was implanted under X-ray fluoroscopy (control group). A total of 4 screws and 2 rods were implanted in each patient. The implantation time and fluoroscopy frequency during implantation of each screw, angle deviation and distance deviation between actual and preoperative planned trajectory by imaging examination, and the occurrence of zygapophysial joint invasion were recorded. Results:In terms of screw implantation time, fluoroscopy frequency, angle deviation, distance deviation, and incidence of zygapophysial joint invasion, the trial group showed superior results compared to the control group, and the differences were significant ( P<0.05). Conclusion:UVN combined with X-ray fluoroscopy-guided percutaneous pedicle screw implantation can yreduce screw implantation time, adjust dynamically, reduce operational difficulty, and reduce radiation damage.
Objective To observe the influence of the bone cement injection volume on the efficacy of percutaneous vertebroplasty(PVP) in elderly patients with osteoporotic vertebral compression fracture(OVCF),and to provide reference for clinicians to choose the volume of bone cement injection.Methods A total of 90 elderly patients with OVCF admitted to Luoyang Orthopedic-Traumatological Hospital of Henan Province from January 2019 to January 2021 were selected as the study subjects.All patients were treated with PVP.According to the ratio of volume of bone cement to the volume of vertebral body(Vbc/Vvb),the patients were divided into low-dose group(0.1<Vbc/Vvb≤0.2),medium-dose group(0.2<Vbc/Vvb≤0.3) and high-dose group(Vbc/Vvb>0.3),with 30 patients in each group.At the time points of before operation, the first day after operation, 3 and 12 months after operation, the patients′ back pain was assessed by visual analogue scale(VAS),and their functional recovery was assessed by Oswestry dysfunction index(ODI).All patients were reexamined with CT on the first to second day after operation to observe the leakage of bone cement.All patients were followed up for 12 months to observe the refracture of the injured vertebral body and adjacent vertebral body.Results There was no significant difference in the VAS score and ODI score among the three groups at the time points of before operation, the first day after operation, 3 and 12 months after operation(P>0.05).The VAS score and ODI score of the patients in the three groups on the first day, 3 and 12 months after the operation were significantly lower than those before operation(P<0.05).The leakage rate of bone cement in the low-dose group, middle-dose group and high-dose group was 13.33%(4/30),16.67%(5/30) and 40.00%(12/30),respectively.The leakage rate of bone cement in the low-dose group and medium-dose group was significantly lower than that in the high-dose group(χ~2=4.022,0.020;P<0.05).There was no statistically significant difference in the leakage rate of bone cement between the low-dose group and medium-dose group(χ~2=1.131,P>0.05).Within 3 months after operation, the refracture rate of patients in the low-dose group, medium-dose group and high-dose group was 3.33%(1/30),0.00%(0/30) and 6.67%(2/30),respectively.There was no statistically significant difference in the refracture rate among the three groups(χ~2=2.069,P>0.05).Within 6 months after operation, the refracture rate of patients in the low-dose group, medium-dose group and high-dose group was 6.67%(2/30),0.00%(0/30) and 6.67%(2/30),respectively.There was no statistically significant difference in the refracture rate among the three groups(χ~2=2.093,P>0.05).Conclusion The PVP with medium-dose bone cement injection(0.2<Vbc/Vvb≤0.3) can effectively relieve the low back pain, promote the functional recovery of OVCF patients, and reduce the incidence of bone cement leakage.

Intervertebral disc degeneration (IDD) is a chronic disease affecting millions of patients; however, its specific etiology is unknown. G protein-coupled receptors (GPRs) are a superfamily of integral membrane receptors in cells, and the receptors respond to a diverse range of stimuli and participate in multiple cellular activities. Here, using RNA-sequencing (RNA-seq) methods and immunohistochemistry, we revealed that G protein-coupled receptor 35 (GPR35) may have a relationship with IDD. Then, we demonstrated that the deletion of GPR35 in nucleus pulposus cells (NPCs) with siRNA or in Gpr35-/- mice significantly alleviated IDD caused by senescence or mechanical stress, further validating the pathological role of GPR35 in IDD. In addition, GPR35 induced the influx of Ca2+ and upregulation of reactive oxygen species (ROS) under mechanical stress in NPCs, which we believe to be the mechanism of GPR35-induced IDD. Finally, GPR35 caused upregulation of ROS in NPCs under mechanical stress, while excessive ROS stimulated the NPCs to express more GPR35 with a significant dose or time response. The u-regulated GPR35 could sense mechanical stress to produce more ROS and perpetuate this harmful cycle. In summary, our study shows that GPR35 plays a critical role in mediating IDD via mediating the influx of calcium ions and upregulating ROS, which implies a strong potential advantage of GPR35 as a prevention and treatment target in IDD.
