Magnetic resonance neurography in analysis of operative safety of transforaminal lumbar interbody fusion in Chinese subjects.

Objective: To measure relevant anatomical variables of lumbosacral nerve root and adjacent structures by magnetic resonance neurography (MRN) and analyze operative safety of transforaminal lumbar interbody fusion (TLIF) in Chinese subjects.

Methods: Twelve normal healthy volunteers (six men, six women) underwent MRN of lumbosacral nerve roots at 3.0 T.

Effects of TGF-β1 and IL-1β on expression of ADAMTS enzymes and TIMP-3 in human intervertebral disc degeneration.

The aim of this study was to investigate the effects of transforming growth factor-β1 (TGF-β1) and interleukin-1β (IL-1β) on the expression of a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS) enzymes and their inhibitor, tissue inhibitor of metalloproteinase 3 (TIMP-3), in human intervertebral disc (IVD) degeneration. Cells from patients with IVD degeneration were cultured with Dulbecco's modified Eagle's medium with Ham's F12 nutrient mixture (DMEM/F12) medium at 37°C in a 5% CO incubator. Cell proliferation was measured by cell counting kit-8 assays with varying concentrations of TGF-β1 and IL-1β in a time-response experiment.

Multifocal osteolytic lesions within lumbar spine in a middle-aged Chinese woman: a benign metastasizing leiomyoma?

Study Design: Case report.

Objective: To describe a case presented as osteolytic lesions involving 2 inconsecutive lumbar, which was pathologically proved to be of smooth muscular origin.

Summary Of Background Data: Smooth muscle tumor of uncertain malignant potential (STUMP) could be diagnosed when the neoplasm showed some malignant behavior, whereas its histologic image revealed very low malignance.
