简介：针灸是在中国的普通处理方法之一，并且它的临床的有效性现在在许多国家被接受了或它全球被扩展了并且作为一种医药形式适用。在中国，临床的实践证明了针灸的指示在神经系统，内分泌系统，免疫系统，循环系统，消化系统，呼吸系统，泌尿系统，生殖系统，血系统，感觉系统和马达包括超过300混乱系统，并且指示逐渐地与针灸的临床的应用程序的开发被创造。自从1949，中国把大重要性纳入了中国药原因的发展，投资了大量钱资助中国药，并且完成了多产的结果，到，作为结果在世界上维持针灸的主角。前面的研究证明了那针灸在临床的实践是有效的，并且它由象nerve-endocrine-im-munenerwork那样的许多过程在双向规定工作，它无疑显示出针灸效果的客观性。上面的研究成就越过世界引起了广泛的注意。

简介：AbstractPediatric skull base lesions are complex and challenging disorders. Safe and comprehensive management of this diverse group of disorders requires the expertise of an experienced multidisciplinary skull base team. Adult endoscopic skull base surgery has evolved due to technologic and surgical advancements, multidisciplinary team approaches, and continued innovation. Similar principles continue to advance the care delivered to the pediatric population. The approach and management of these lesions varies considerably based on tumor anatomy, pathology, and surgical goals. An understanding of the nuances of skull base reconstruction unique to the pediatric population is critical for successful outcomes.
