Previous studies had indicated that interleukin-1 beta (IL-1β) gene single nucleotide polymorphisms (SNPs) associate with different inflammatory diseases. However, potential links between these polymorphisms and susceptibility to extremity chronic osteomyelitis (COM) in Chinese population remain unclear. This study aimed to investigate relationships between IL-1β gene polymorphisms (rs16944, rs1143627, rs1143634 and rs2853550) and the risk of developing extremity COM in Chinese population. Altogether 233 extremity COM patients and 200 healthy controls were genotyped for the four tag SNPs of the IL-1β gene using the SNapShot genotyping method. Comparisons were performed regarding genotype distribution, mutant allele frequency and four genetic models (dominant, recessive, homozygous and heterozygous models) of the 4 SNPs between the two groups.Aim

Previous studies have indicated that TNF-α and lymphotoxin-α (LTA) gene polymorphisms associate with the development of several different inflammatory diseases. However, potential associations of such gene polymorphisms with the susceptibility to extremity chronic osteomyelitis remain unknown. This study aimed to investigate potential links between TNF-α gene polymorphisms (rs1800629, rs361525, rs1799964, rs1800630, rs1799724 and rs1800750) and LTA gene polymorphism (rs909253) and the risk of developing extremity chronic osteomyelitis in Chinese population. A total of 233 patients with extremity chronic osteomyelitis and 200 healthy controls were genotyped for the above 7 polymorphisms of TNF-α and LTA genes using the genotyping method*.Aim
Method
This study aimed to explore the role of miR-320a in the pathogenesis of osteoarthritis (OA). Human cartilage cells (C28/I2) were transfected with miR-320a or antisense oligonucleotides (ASO)-miR-320a, and treated with IL-1β. Subsequently the expression of collagen type II alpha 1 (Col2α1) and aggrecan (ACAN), and the concentrations of sulfated glycosaminoglycans (sGAG) and matrix metallopeptidase 13 (MMP-13), were assessed. Luciferase reporter assay, qRT-PCR, and Western blot were performed to explore whether pre-B-cell leukemia Homeobox 3 (PBX3) was a target of miR-320a. Furthermore, cells were co-transfected with miR-320a and PBX3 expressing vector, or cells were transfected with miR-320a and treated with a nuclear factor kappa B (NF-κB) antagonist MG132. The changes in Col2α1 and ACAN expression, and in sGAG and MMP-13 concentrations, were measured again. Statistical comparisons were made between two groups by using the two-tailed paired Objectives
Methods
In order to evaluate the effectiveness of the Mobi-C implant
in cervical disc degeneration, a randomised study was conducted,
comparing the Mobi-C prosthesis arthroplasty with anterior cervical
disc fusion (ACDF) in patients with single level cervical spondylosis. From January 2008 to July 2009, 99 patients were enrolled and
randomly divided into two groups, those having a Mobi-C implant
(n = 51; 30 men, 21 women) and those undergoing ACDF (n = 48; 28
men, 20 women).The patients were followed up for five years, with
the primary outcomes being the Japanese Orthopaedic Association
score, visual analogue scale for pain and the incidence of further
surgery. The secondary outcomes were the Neck Disability Index and
range of movement (ROM) of the treated segment.Aims
