目的:探讨B超监测下输尿管镜治疗输尿管结石的临床疗效及可行性。方法:2007年12月~2008年12月采用B超监测下输尿管镜治疗输尿管结石患者34例,结石位于上段4例,中段11例,下段19例。结果:一次性碎石治愈者33例,一次性碎石成功率97%,手术时间(40±15)min,术后2~7天排尽结石,术后住院平均时间3.5(2～5)天。结论:B超监测下输尿管镜治疗输尿管结石对于手术操作者易于随时动态观察结石情况,对于大于0.4 cm的碎石块无遗漏,增加术中一次碎石成功率,可行性高。
Joint attention deficit is one of the core disorders in children with autism, which seriously affects the development of multiple basic skills such as language and communication. Virtual reality scene intervention has great potential in improving joint attention skills in children with autism due to its good interactivity and immersion. This article reviewed the application of virtual reality based social and nonsocial scenarios in training joint attention skills for children with autism in recent years, summarized the problems and challenges of this intervention method, and proposed a new joint paradigm for social scenario assessment and nonsocial scenario training. Finally, it looked forward to the future development and application prospects of virtual reality technology in joint attention skill training for children with autism.
