目前,我国结核病疫情严重,是全球发病率高的国家之一.儿童作为易感人群,其骨与关节结核病的发病例数有上升趋势.脊柱结核是最常见的骨关节结核,约占骨结核的50％,如诊治有误,可引起较高的致残率[1].尤其是生长发育期的儿童脊柱,一旦受结核感染,其受到的影响要比成人的严重[2].小儿脊柱结核常合并严重后凸畸形,这不仅影响美观,更重要的可能会出现心肺功能不全,甚至脊髓受压而导致瘫痪;而且严重的后凸畸形给患
目的观察早期高压氧治疗对注射玻尿酸所致皮肤缺血的疗效。方法将注射玻尿酸所致皮肤缺血患者42例依据高压氧治疗情况分为2组：A组，给予常规治疗，部分患者高压氧治疗均于72 h后进行。B组，常规治疗基础上均于注射后72 h内行高压氧治疗。记录2组患者显效时间，并将高压氧开始治疗时间与显效时间行Pearson相关性分析；于注射后第10天比较2组患者的显效率。结果A组平均显效时间为(13.2±2.8)d，B
