Osterix (Osx) is an osteoblast-specific transcription factor required for osteoblast differentiation. Inhibition of Wnt pathway by Osx highlights the potential feedback control mechanisms involved in bone formation. Hypoxia-inducible factor-1α (HIF-1α) a master regulator hypoxia. HIF-1α has been reported to couple angiogenesis osteogenesis. Our recent study demonstrated that and cooperatively regulate VEGF expression osteoblasts. Effects hypoxia/HIF-1α on proliferation related are not well...

This study was a retrospective review of prospectively collected clinical data.To evaluate the and radiologic outcomes computer-assisted minimally invasive spine surgery transforaminal lumbar interbody fusion (CAMISS-TLIF) open TLIF for treatment 1-level degenerative disease.Minimally is becoming increasingly popular; however, limited space high rate hardware complications associated with this method are challenging to surgeons. Computer-assisted navigation has potential dynamically show...

There is no available literature for comparison on muscle atrophy between the "stand-alone" oblique lateral interbody fusion (OLIF) and regular OLIF (i.e., combined with percutaneous pedicle screws fixation (PPSF) in patients spondylolisthesis). This study aimed to identify changes back two surgeries.This was a retrospective cohort of who underwent or OLIF+PPSF at Beijing Jishuitan Hospital Shanghai ChangZheng 07/2014 10/2017. Computed tomography (CT) used measure functional cross-sectional...

To compare the safety and effectiveness of robot-assisted minimally invasive transforaminal lumbar interbody fusion (Mis-TLIF) oblique (OLIF) for treatment single-level degenerative spondylolisthesis (LDS).This is a retrospective study. Between April 2018 2020, total 61 patients with treated OLIF (28 cases, 16 females, 12 males, mean age 50.4 years) or Mis-TLIF (33 18 15 53.6 were enrolled evaluated. All pedicle screws implanted percutaneously assisted by TiRobot system. Surgical data...

Epidural adhesion between the spinal dura and surrounding fibrous tissue often occurs post-laminectomy, resulting in clinical symptoms such as nerve compression severe pain. In this study, we report a drug-loaded double-layered electrospun nanofiber membrane to prevent occurrence of epidural adhesion. The nanofibers both layers are made mixture polycaprolactone (PCL) chitosan (CS) but at different weight ratios. bottom layer contacting is loaded with meloxicam (MX) inflammation. top that...

Abstract Bone regeneration involves a series of events in coordinated manner, including recruitment mesenchymal stem cells, induction immune response, inflammatory activity and vascular ingrowth. The microenvironment bone is hypoxic. Low oxygen tension (hypoxia) promotes the upregulation several signaling molecules. primary mediating factor hypoxia-inducible factor-1 (HIF-1). Hypoxia stimulates expression variety cytokines from fibroblasts, endothelial cells osteoblasts. TNF-α key...

Little is known about the effect of lumbar intervertebral disc herniation (LDH) on bone mineral density (BMD), and few previous studies have used quantitative computed tomography (QCT) to assess whether staging LDH correlates with vertebral trabecular volumetric (Trab.vBMD). To explore relationship between Trab.vBMD LDH, seven hundred fifty-four healthy participants aged 20–60 years were enrolled in study from an ongoing degeneration spine knee June 2014 2017. QCT was measure L2–4 magnetic...

Robot-assisted open surgery (RA-OS) is now commonly used in traditional open-exposure spinal screw placement surgery. With the help of robots, robot-assisted minimally invasive (RA-MIS) can achieve less bleeding and tissue damage percutaneous insertion. While research comparing safety accuracy between RA-MIS RA-OS insufficient. This study aims to compare effects thoracic lumbar spine.This was a prospective cohort evaluating 208 patients undergoing insertions from July 2020 September 2021....

Objective To evaluate the relationship between preoperative imaging differences and prognosis in patients with cervical spondylosis vertigo who underwent total disc replacement (TDR). Methods This was a retrospective study of treated single-segment TDR. The severity pre- postoperative evaluated separately. Paired samples t-tests were used to compare symptoms before after surgery. Characteristics plain films, computed tomography myelography magnetic resonance compared different outcomes by...

For patients with degenerative spondylolisthesis, whether additional posterior fixation can further improve segmental alignment is unknown, compared stand-alone cage insertion in oblique lumbar interbody fusion (OLIF) procedure. The aim of this study was to compare changes the radiographical following and same procedure setting OLIF for spondylolisthesis. A retrospective observational study. Selected consecutive spondylolisthesis underwent from July 2017 August 2019. Five radiographic...

This study aimed to compare the clinical outcomes between oblique (OLIF) and transforaminal lumbar interbody fusion (TLIF) for patients with degenerative spondylolisthesis during a 2-year follow-up.Patients symptomatic who underwent OLIF (OLIF group) or TLIF (TLIF were prospectively enrolled in authors' hospital followed up 2 years. The primary treatment effects [changes visual analog score (VAS) Oswestry disability index (ODI) from baseline] at years after surgery; these compared two...

A rapid, simple, and accurate voltammetric method for quantifying total inorganic arsenic in rice was described this work. The simplified sample pretreatment involved the addition of a mixed solution nitric acid L-cysteine, which facilitated simultaneous extraction speciation (As(III)). To eliminate interference from complex matrices, magnetic composites were employed to absorb copper other potential interference. Furthermore, As(III) detected using linear stripping voltammetry with...
