Objective To study effects and other related problems of surgery for patients with cervical spine fracture and ankylosing spondylitis.Methods Twelve patients with cervical spine fracture and ankylosing spondylitis were treated with surgery from April 1986 to April 2004.All eases were studied retrospectively.They were followed up for an average of 67.5 months and their complete clinical data were kept.The neurological function was evaluated by ASIA (American Spinal Injury Association) impairment scale,and the image analyzing software (Image-Pro Plus 5.1) was used to measure the angles of superior and inferior vertebral bodies of the fusion segment at flexion and extension positions.The difference between flexion and extension angles,?,served as the parameter of interspinal movement.According to the definition of spinal fusion by FDA (Food and Drug Administration),the?≥4?was considered as nonfusion.Other related problems were discussed by descriptive study.Results The average improvement in the nine patients with neurological injury was 1.3 ASIA grades.The injured segments in 10 cases were treated with fusion,of whom nine were fused by internal fixation.The fusion rate was 100%.Three cases were scheduled to have laminoplasty,but two had to receive laminectomy instead because of intraoperative complete fracture at the hinged side.Ten patients were complicated by insufficient function of major organs preop- eratively,and endotracheal intubation was difficult to perform in eight cases.Postoperative complications occurred in three cases,but fortunately healed completely.There were no deaths or fatal complications.Conclusions The neurological function can be improved by surgery for patients with cervical spine fracture and ankylosing spondylitis. Although the cervical spine is instable for most of the patients,fusion with internal fixation is indicated and can be successful.Those who had preoperative systemic diseases are likely to suffer from postoperative complications.The difficult endotracheal intubation is a common intraoperative problem.

AIM: To investigate the level of ET-1 produced by cultured human bronchial epithelial cells (HBECs) under injury and the effects of injured HBECs on ET-1 production in sub-epithelial fibroblasts. The interaction between ET-1 and matrix metalloproteinase-9(MMP-9) was detected in HBECs under damage. The purpose of the study is to evaluate the effect of injured HBECs related to ET-1 release on airway remodeling in asthma. METHODS: ET-1 level was detected in supernatants from cultured HBECs 12 h after being treated with either mechanical scraping or LPS stimulation or mechanical scraping plus LPS, as well as from subepithelial fibroblasts cocultured with mechanical damaged HBECs. It was also measured in the supernatant from HBECs transfected with MMP-9 expression plasmid. MMP-9 activity was assessed in supernatants from HBECs stably transfected with pEGFPc1 -antisense-ET-1 converting enzyme(ECE) RNA. RESULTS: It was found that there was an increase in ET-1 level in supernatants from HBECs either treated with mechanical scraping plus LPS or transiently transfected with MMP-9 plasmid, as well as from sub-epithelial fibroblasts cocultured with mechanical scraping HBECs compared with that in controls. Gelatin zymography showed a obviously attenuated gelatinolytic activity of MMP-9 in conditioned media of HBECs expressing antisense ECE RNA after mechanical damage. CONCLUSIONS: Airway epithelial cells under injury are able to overproduce ET-1 as well as initiate ET-1 release from sub-epithelial fibroblasts, MMP-9 produced by injured bronchial epithelial cells may also increase ET-1 processing leading to ET-1 production further. The interaction between ET-1 and MMP-9, both of which enhanced in damaged HBECs, may play an important role in airway inflammation related to airway remodeling in asthma.
