BACKGROUND Far lateral lumbar disc herniation (FLLDH) accounts for 2.6% to 11.7% of all lumbar herniated discs. Numerous surgical approaches have been described for treating this condition. The purpose of this study was to evaluate minimally invasive surgical techniques for the treatment of FLLDH. METHODS From June 2000 to March 2006, 52 patients with(More)
OBJECTIVE To prospectively evaluate the feasibility, safety and efficacy of the percutaneous pedicle screw fixation through the pedicle of fractured vertebra in the treatment of type A thoracolumbar fractures using Sextant system in the retrospective non-randomized case-control study. METHODS A total of 38 consecutive non-randomized patients with type A(More)
OBJECTIVES To retrospectively analyze the treatment of lumbar spondylolisthesis using minimally invasive and open transforaminal lumbar interbody fusion (TLIF), and compare the clinical results of two techniques. METHODS From June 2006 to May 2010, 371 patients with lumbar spondylolisthesis grade 1 and 2 were treated with TLIF, pedicle screw fixation and(More)
Cardiotrophin-1 (CT-1), a muscle-derived cytokine, supports the survival of motoneuronsin vivo andin vitro. The present study investigated whether adenoviral huCT-1 gene transfer protected injured neurons from cell death or atrophy and promoted regeneration of rubrospinal tract (RST) after spinal cord injury in adult rats. Administration of the adenoviral(More)
The associations between SNPs in intron 6 and intron 7 of the bovine diacylglycerolacyltransferase (DGAT2) gene and growth traits in purebred Nanyang cattle (n=131) were reported in this study. Alleles detected in intron 6 were allele A and B with frequencies of 0.875 and 0.125, respectively; alleles detected in intron 7 were allele N and M with frequencies(More)
OBJECTIVE To investigate the surgical procedures, options and surgical indications for far-lateral lumbar disc herniation between three different minimally invasive procedures. METHODS From January 2000 to October 2006, 52 patients with far-lateral lumbar disc herniation (29 males and 23 females, with the average age of 41.5 years) were treated with(More)
Drought stress is one of the major adverse environmental factors reducing plant growth. With the aim to elucidate the underlying molecular basis of rice response to drought stress, comparative transcriptome analysis was conducted between drought susceptible rice cultivar Zhenshan97 and tolerant cultivar IRAT109 at the seedling stage. 436 genes showed(More)
OBJECTIVE To evaluate the surgical procedure of endoscopic transforminal discectomy, bone grafting and Dynalok pedicle screw fixation under X-Tube operation system in the treatment of lumbar disc herniation combined with segmental instability and/or pars defected spondylolithesis. METHODS From June 2004 to May 2006, 42 patients with classic features of(More)
Several types of stem cells have been successfully demonstrated to exist in the human degenerated intervertebral disc (IVD), which is composed of annulus fibrosus (AF), nucleus pulposus (NP) and cartilage endplate (CEP). However, the differences in the biological characteristics among these and bone marrow derived mesenchymal stem cells (BM-MSCs) remain(More)
OBJECTIVE To evaluate the clinical results of, and surgical techniques for, microendoscopic (METRx) decompression of extraforaminal entrapment of the L5 spinal nerve at the lumbosacral tunnel. METHODS Five patients with extraforaminal entrapment of the L5 spinal nerve in the lumbosacral tunnel were treated in our department, including three men and two(More)
