The clinical criteria for both diagnosis and efficacy evaluation of disease are also needed. To include all symptoms, tongue manifestations and pulse presentations into case report form, and to compare the differences in these clinical parameters between effective and noneffective cases by multivariate analysis may be helpful to find more specific indications for therapeutic protocol of TCM. Furthermore, It is suggested that two or more clinical trials on one therapeutic protocol are needed to identify its accurate indications.

中医药规范化治疗方案的研究必须体现中医基本理论，遵循现代医学临床试验设计方法以及利用现代医学关于疾病诊断和疗效判断的标准，应将中医证候相关信息纳入临床试验的检查项目之中，开展两次或多次的临床试验，利用多元统计分析方法，对比分析有效和无效人群的特点，寻求与中医药治疗方案有效结局相关的主观症状、舌象和脉象，从而找到该治疗方案的最佳适应症，形成规范的治疗方案。

The orthogonal design of fifteen factors and two levels is made. At the same time, fifteen components are tested and five key factors have been selected out .Finally the second orthogonal design of five factors and four levels is carried on and the new optimum component of artificial diet of rice stem borer is reached.

同时，本文从已报道的不同二化螟人工饲料中选择了15种饲料成分，采用15因子2水平的正交试验设计，对这15种成分进行了优化，并从中筛选出5个关键因子，然后对这5个关键因子进行了5因子4水平的第二次正交试验优化设计，得出了二化螟人工饲料新的优化配方。

This study applied the response surface design to investigate the response of nitrogen, phosphorus and potassium on the growth of naturally regenerated chamaecyparis stand in Chi-lan-shan, and to investigate the response of thinning, pruning and fertilizing on the growth of Calocedrus formosana stand in Forest Station of National ILan University.

本研究以反应曲面试验设计，於栖兰山桧木天然更新林地进行氮、磷、钾施肥试验，另於国立宜兰大学实验林场台湾肖楠人工林进行疏伐、修枝、施肥试验。

Our experiment aim at use the acupuncture method"Wang's Jiaji points"which created by the famous doctor Leting wang from Beijing hospital of TCM at the early days of the stroke patients to prevent and treat hypermyotonia,prevent muscle spasm or lessen the spasm level,to improve the stroke patient's ADL.that study is a prospective , randomized, double-blind,parallel-group,use the random digits table method,and compared with the"twelve points of hands and feet",which used frequently at acupuncture department of Beijing hospital of TCM.we use the NIHSS scale, improved Ashworth scale,domestic Fugl-Meyer scale, castigatory MBI scale to score the patients'muscular tension and motor function improvement condition.

本试验旨在在中风病人患病早期应用北京中医院名老中医王乐亭先生的&王氏夹脊穴&预防性治疗肌张力增高，防止肌痉挛的出现或减轻其痉挛程度，以改善中风患者的生活质量。在试验设计方面以北京中医院针灸科目前治疗中风应用较多的&手足十二针&为对照治疗方法采用随机、单盲、平行对照设计。并应用NIHSS、改良的Ashworth量表、国内简化的Fugl-Meyer运动评分法、修订的巴氏指数评分方法对患者治疗前后进行评分以了解患者肌张力增高情况及运动功能改善情况。

In 3×3 Latin square design, three wethers of Inner Mongolian White Cashmere goats (25~30 kg) with the same father, fitted with permanent cannulas at the proximal duodenum, and with carotid artery, mesenteric and portal venous catheters were used to investigate the effect of absorbable amino acid pattern in the small intestine, which were M, M90+C10 and M80+C20, on absorption and metabolism of amino acids in IMWC goats.
