Intervertebral disc degeneration (IVDD) is a chronic degenerative disease with a complex pathophysiological mechanism. Increasing evidence suggests that the NOD-like receptor thermal protein domain associated protein 3 (NLRP3)-mediated pyroptosis of nucleus pulposus cells (NPCs) plays a crucial role in the pathological progression of IVDD. Pyroptosis is a novel form of programmed cell death characterized by the formation of plasma membrane pores by gasdermin family proteins, leading to cell swelling, membrane rupture, and the release of inflammatory cytokines, which trigger an inflammatory response.

Background: Osteoporosis (OP) is a progressive metabolic disorder that is difficult to cure clinically. The molecular mechanisms of OP urgently need to be further examined. This study was designed to explore the potential function of circ_0027885 during osteogenic differentiation, as well as the systematic interactions among circ_0027885, miR-203-3p and runt-related transcription factor 2 (RUNX2).

Background: Calycosin (CA), a flavonoids component, has demonstrated potential neuroprotection effects by inhibiting oxidative stress in spinal cord injury (SCI) models. This study aims to investigate the impact of combined rehabilitation training (RT) and calycosin therapy on neurological function following SCI, primarily by assessing changes in motor function recovery, neuronal survival, neuronal oxidative stress levels, and neural proliferation, in order to provide novel insights for the treatment of SCI.

Materials And Methods: The SCI model was constructed by compressing the spinal cord using vascular clamps.

Objective: The objective of this study was to compare the clinical and radiological outcomes of endoscopic transforaminal lumbar interbody fusion (Endo-TLIF) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF).

Methods: This retrospective study included 110 patients with single-level lumbar degenerative disease who underwent Endo-TLIF or MIS-TLIF between January 2019 and December 2021. Patients were divided into Endo-TLIF (n = 55) and MIS-TLIF groups (n = 55).

Context: Degenerative changes in the lumbar spine more commonly cause spinal stenosis and with the aging of society, its incidence is on the rise. Endoscopic spinal surgery is a minimally invasive technique for decompression. The efficacy of percutaneous, endoscopic, large-channel fusion and transforaminal lumbar interbody fusion (TLIF) need confirmation by more studies.

Objective: This study aimed to evaluate short-term clinical efficacy of percutaneous endoscopic posterior lumbar interbody fusion (Endo-LIF) in the treatment of obese patients with lumbar degenerative diseases (LDD).

Methods: Patients who underwent single-level lumbar fusion surgery from July 2020 to July 2022 were retrospectively analyzed in this study. The main inclusion criterion was a body mass index (BMI) ≥30kg/m.

Article Synopsis
  • The study aimed to evaluate the effectiveness of unilateral-approach endoscopic lumbar interbody fusion (Endo-LIF) for treating lumbar spondylolisthesis with symptoms in both legs.
  • 43 patients underwent the procedure, and important radiological measurements like disk height and foraminal areas were analyzed before and after surgery.
  • Results showed significant improvements in both clinical symptoms, as evidenced by decreased pain scores, and radiological measures, suggesting that this surgical approach is a viable treatment option for the condition.

Intervertebral disk degeneration remains one of the most challenging health problems. In the current study, allopurinol was loaded into the chitosan nanoparticles and then incorporated into chitosan/alginate hydrogels and then further studied for its disk regeneration potential in a rat model. In vitro studies were performed to characterize the hydrogel system, including scanning electron microscopy, cell viability assay, cytoprotection assay, cell migration assay, swelling assay, and drug release assay.

Study Design: A retrospective matched case-control study.

Objective: This study aims to investigate the value of Subcutaneous Lumbar Spine Index (SLSI) as a predictor of early surgical site infection (SSI) after lumbar intervertebral fusion surgery.

Methods: A retrospective case-control study was performed on patients who underwent transforaminal lumbar interbody fusion (TLIF) from January 1, 2014 to December 31, 2019 in a single institution.

Hippo signaling regulates the balance between cell proliferation and apoptosis to control the size of organs during development. Appropriate Hippo signaling is associated with stem cell differentiation, and inappropriate signaling can result in tumorigenesis and cancer. Hippo signaling activity is influenced not only by biochemical signals but also by mechanical force and the cytoskeleton transmitted through cell-cell junctions and cell-matrix adhesions.

Background: Aberrant apoptosis in nucleus pulposus (NP) cells is the primary cause of intervertebral disc degeneration (IDD). In contrast, a large number of studies have confirmed that autophagy may protect NP cells from apoptosis. Sinomenine is an alkaloid monomer, which has been reported to stimulate cell autophagy.

Rationale: Spinal metastases are always associated with specific pain of back and limbs caused by nerve root compression. Although percutaneous endoscopic lumbar discectomy (PELD) has been widely performed on patients with back and radicular pain originating from lumbar disc herniation, this minimally invasive surgery is rarely used for the treatment of spinal metastases.

Patient Concerns: A 71-year-old woman with colon cancer and a known L3 vertebral body metastasis presented with significant progressive pain of low back and limbs.

Osteosarcoma (OS) is the most common highly malignant bone tumor in teens. Vasculogenic mimicry (VM) is defined as de novo extracellular matrix-rich vascular-like networks formed by highly aggressive tumor cells. We previously reported the presence of VM and it is an unfavorable prognostic factor in OS patients.

Vasculogenic mimicry (VM) is a special type of vascular channel formed by tumor cells without endothelial cell participation. Migration-inducing gene 7 (MIG-7) plays an important role in regulating VM. In this study, immunohistochemical staining was used to detect MIG-7 in tissue specimens from 141 primary osteosarcoma patients, and the relationship between MIG-7 and VM was examined.

Notochord nucleus pulposus cells are characteristic of containing abundant and giant cytoplasmic vacuoles. This review explores the embryonic formation, biological function, and postnatal exhaustion of notochord vacuoles, aiming to characterize the signal network transforming the vacuolated nucleus pulposus cells into the vacuole-less chondrocytic cells. Embryonically, the cytoplasmic vacuoles within vertebrate notochord originate from an evolutionarily conserved vacuolation process during neurulation, which may continue to provide mechanical and signal support in constructing a mammalian intervertebral disc.

Hepatocellular carcinoma (HCC) is the third most common malignant tumor worldwide and has a poor survival rate. The poor prognosis can be attributed to several of the characteristics of HCC, such as fast infiltrating growth, early-stage metastasis, high-grade malignancy and poor therapeutic efficacy. The current study presents a case of HCC that was metastatic to the spinal canal with an unknown primary site and discusses the diagnostic probabilities.
