〔摘要〕 小儿之体，阴阳二气稚嫩，尚未成熟，在生长发育过程中，小儿随着阳气的升发，不断建立新的阴阳平衡状态。“少阳学说”可以全面阐述小儿的生理特性和病理特点，强调少阳在阴阳交会、表里转换、脏腑协调、生长发育以及情志调节等方面的关键枢纽作用。“少阳为枢”作为“少阳学说”的核心理论，可体现小儿生长发育中的动态平衡。若少阳枢机正常，则阴平阳秘，五脏安和；若少阳枢机不利，则阴阳失衡，脏腑失和，气机郁滞，疾病由生。四逆散作为调和少阳枢机的经典方剂，通过疏肝解郁、升阳降逆，调节小儿气机，促进阴阳平衡。在儿科临床多种疾病中运用四逆散可疏利枢机，助枢纽功能恢复，附验案一则以供临床参考。

During the growth and development of children， as their yang qi rises， they continuously establish new states of yin-yang balance. The "Shaoyang theory" comprehensively elucidates the physiological and pathological characteristics of children ......
