X-linked hypophosphataemic rickets (XLHR) is a disease of impaired bone mineralization characterized by hypophosphataemia caused by renal phosphate wasting. The main clinical manifestations of the disorder are O-shaped legs, X-shaped legs, delayed growth, and bone pain. XLHR is the most common inheritable form of rickets, with an incidence of 1/20 000 in humans. It accounts for approximately 80% of familial cases of hypophosphataemia and serves as the prototype of defective tubular phosphate (PO43+) transport, due to extra renal defects resulting in unregulated The genome DNA samples of all members in the pedigree were extracted from whole blood. We sequenced all exons of the Objectives
Methods
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

Diagnosis of clavicle osteomyelitis (OM) is often difficult with delayed treatment due to the lower incidence of this disease. The present study aimed to summarize clinical experience with clinical features and treatment of clavicle OM. We systematically searched the Pubmed database to identify studies regarding clinical characteristics and management of clavicle OM from 1980 to 2016, with publication language limited to English. Effective data were collected and pooled for analysis.Aim

Cyclooxygenase-2 (COX-2) enzyme is one of the major mediators during inflammation reactions, and COX-2 gene polymorphisms of rs20417 and rs689466 have been reported to be associated with several inflammatory diseases. However, potential links between the two polymorphisms and risk of developing post-traumatic osteomyelitis remain unclear. The present study aimed to investigate associations between the rs20417 and rs689466 polymorphisms and susceptibility to post-traumatic osteomyelitis in Chinese population. A total of 189 patients with definite diagnosis of post-traumatic osteomyelitis and 220 healthy controls were genotyped for rs20417 and rs689466 using the genotyping method*. Chi-square test was used to compare differences of genotype distributions as well as outcomes of five different genetic models between the two groups.Aim
