Besides the MHC gene, HLA-B27, ERAP1 is one of the non-MHC genes which also play key roles in the pathogenesis of AS. It has been reported that there is an association between ERAP1 polymorphisms and AS Risk. However, the results were inconclusive. The aim of the current study was to determine the contribution of ERAP1 polymorphisms to ankylosing(More)
—In the problem of routing in multi-hop wireless networks, to achieve high end-to-end throughput, it is crucial to find the " best " path from the source node to the destination node. Although a large number of routing protocols have been proposed to find the path with minimum total transmission count/time for delivering a single packet, such transmission(More)
INTRODUCTION Accurate prediction of the biochemical recurrence (BCR) is critical for patients after intended curative therapy like radical prostatectomy (RP) or definitive radiotherapy for prostate cancer. Glutathione-S-transferases polymorphisms as well as hypermethylation of GSTP1 and functional genes in carcinogenesis, including tumor suppression gene(More)
RunX2 has been identified to crucially regulate the osteolysis in giant cell tumor of bone. MiR-30a is an intronic miRNA identified as tumor suppressor, but little is known about its role in giant tumor cell of bone. In our research, we reported miR-30a was down-regulated in GCT whereas RunX2 was highly expressed. Further research proved that miR-30a can(More)
BACKGROUND Chordoma in the spine is relatively rare, and minimal information has been published in the literature regarding this subject. Moreover, there are controversies over prognostic factors of this disease. METHODS A retrospective analysis of chordoma in the spine was performed by survival analysis. Local relapse-free survival (LRFS) and overall(More)
In mobile wireless networks, the emerging proximity-based applications have led to needs for highly effective and energy-efficient neighbor discovery protocols. However, existing works cannot realize the optimal worst-case latency in symmetric case, and their performances with asymmetric duty cycles can still be improved. In this work, we investigate(More)
PURPOSE Aggressive giant cell tumor (GCT) is an important subtype of GCT and is relatively rare in the spine. There is little published information regarding this subject. The objective of our study is to discuss prognostic factors for primary aggressive GCT in the spine. METHODS A retrospective study of patients who had primary aggressive GCT in the(More)
STUDY DESIGN A retrospective study was performed. OBJECTIVE To illustrate the characteristics of spine tumors during pregnancy and obtain better insight into therapeutic strategies of such tumors by analyzing 21 cases treated in Changzheng Hospital and reviewing previous reports in the literature. SUMMARY OF BACKGROUND DATA The concurrence of spine(More)

BACKGROUND Various therapeutic approaches have been proposed for the treatment of pediatric patients with eosinophilic granuloma (EG) of the cervical spine. Our aim was to discuss and present our experience with the individualized surgical intervention of pediatric cervical EG complicated with neurologic deficits and/or spinal instability. METHODS We(More)
