目的:本课题研究以通过古代文献检索的方式,检索文献来源于《中华医典》第五版所收录的中医古籍,收集和整理有关关元穴与命门穴主治内科病症的古代文献,将其相关条文梳理归纳并进行统计。总结关元穴与命门穴在内科系统的主治病症规律,并探讨其临床应用特点,为临床应用研究提供文献参考。方法:以《中华医典》第五版为中医古代文献的检索源,收录到民国为止以前历代古籍较为完善的版本。为了确保检索的完整性,采用关键词进行检索,以腧穴的名称和别名为检索的关键词,并以简体字和繁体字合并检索和摘录。检索出的条文经过计算机检索和人工阅读,删除重复的文献,参照中国中医药出版社出版的全国高等中医药院校规划教材(新世纪第四版)及《中华人民共和国国家标准——中医临床中诊疗术语(疾病部分)》对古文献所描述的病症进行科别区分和病症名称统一。按照文献的纳入、排除标准选取符合主治内科病症的条文及病案。先将相关文献以关元穴和命门穴主治内科病症分为两大类,再按照内科的7个系统:肺系、心脑系、脾胃系、肝胆系、肾膀胱系、气血津液系、肢体经络系进行归类。对每条文献都要注明其出处、系别及主治的病症,并运用频数统计方法对二穴主治的内科病症进行统计。采用微软Excel电子表格建立数据档案及记录频次统计的结果。通过频数统计结果的表示后,根据计算公式:平均频次等于总频次/病症种类,以此为标准,将大于平均频次的病症种类作为优势病种。总结二穴主治内科各系统的优势病种以及主治应用规律。探讨二穴的主治规律特点和二穴的应用异同。结果:(1)经检索后,有关关元穴的条文有1712条,符合标准的条文共有397条,有关命门穴的条文有3760条,符合标准的条文共有55条。(2)经病症频次统计后,关元穴主治内科病症种类为35种,其中肺系:3种病,心脑系、肝胆系、气血津液系、肢体经络系:各4种病,脾胃系、肾膀胱系:各8种病。而命门穴主治内科病症种类有16种,其中脾胃系、肝胆系:各2种病,心脑系、肾膀胱系、气血津液系、肢体经络系:各3种病。(3)根据计算公式:平均频次等于总频次/病症种类,以此为标准,将大于平均频次的病症种类作为优势病种。总结出关元穴主治的优势病种为12种,其频次从高到低依次为:“泄泻”、“积聚”、“淋证”、“腹痛”、“感冒”、“遗精”、“中风”、“癃闭”、“血证”、“黄疸”、“霍乱”、“头痛”。关元穴在脾胃系统的应用频次最多,其次是肾膀胱、肝胆系统。命门穴主治的优势病症种类有4种,其频次从高到低依次为:“腰痛”、“头痛”、“遗精”、“血证”。命门穴在肢体经络系统应用的频次最多,其次是肾膀胱、气血津液系统。结论:关元穴与命门穴都用于治疗内科各系统的病症。关元穴与命门穴均可治疗肾膀胱系的病症,尤其是在治疗“遗精”关元穴与命门穴可共同配伍应用。关元穴多偏于治疗脾胃系病症、肝胆系病症,而命门穴多偏于治疗肢体经络系病症、气血津液系病症。二穴虽有相同的主治范围,但二穴的主治应用上均有各自的特点,其应用的特点与二穴特异性有着密切相关。

We examined experimentally the flapping performance in terms of aerodynamic force generation of an insect-inspired flapper actuated by both of original LIPCA and compressed LIPCA. Flapping tests for two artificial wing shapes of horse botfly and hawk moth were conducted at the wing rotation angle of 60° and a flapping frequency range from 6 Hz to 12 Hz to find the optimum flapping frequency and to investigate the effect of compressed LIPCA and wing shape on the force generation. Flapping tests in the vacuum were also undertaken to measure the induced inertia force. The aerodynamic force was calculated by subtracting the inertia force from the total force measured in the air. It was found that the average inertia force was relatively small when compared with the average total force. The use of the compressed LIPCA could significantly improve the flapping angle of the flapper from 110° to 130° (18.2% increase) resulting in 24.5% increase in the average aerodynamic force. It was also found that flapper with hawk moth wings could produce larger force than the flapper with horse botfly wings.
