ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the efficacy of three categorized formulas for tonifying Shen yang, i.e. Shenqi Pill (SP), Yougui Pill (YP), and Yougui Drink (YD) based on rough set, thus exploring the law of compatibility between the core herbs and the edge herbs as well as the law of compatibility between the yang-tonifying herbs and the yin-tonifying herbs in the core herbs.</p><p><b>METHODS</b>The rats were divided into the normal group, the Shen-yang deficiency model group, and the original prescription group, the core herbs group, and the edge herbs group of this three categorized formulas for tonifying Shen yang, 11 groups altogether. Thyroxine (T4), cortisol (CORT), and testosterone (T) were detected respectively. The decision rules model based on rough set was set up, the interactions between various herbs were analyzed according to the decision rules.</p><p><b>RESULTS</b>There were synergies between yam and cinnamon, yam and aconite, as well as yam and wolfberry. Poria alisma, Cortex Moutan, and oriental waterplantain tuber had no effect themselves, but they had synergistic effects with the core herbs in SP. Angelica had a certain effect itself, but its functions were different to different core herbs in YP. Licorice had no effect itself, and it was antagonistic with the core herbs in YD.</p><p><b>CONCLUSIONS</b>The compatibility of core herbs of categorized formula for tonifying Shen yang should focus on benefiting both yin and yang, as well as mutual rooting of yin-yang. Appropriate edge herbs should be chosen for compatibility according to different core herbs. The decision rules model based on rough set has a good prospect in exploring the law of compatibility of the categorized formulas.</p>

<p><b>OBJECTIVE</b>To evaluate the key indicators in the pituitary-target gland axes in the animal model of Shen-yang deficiency syndrome (SYDS).</p><p><b>METHODS</b>The 8 biological indicators [thyroid stimulating hormone (TSH), 3, 3', 5-triiodothyronine (T3), thyroxine (T4), luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone (T), adrenocorticotropic hormone (ACTH), and cortisol (CORT)] in the pituitary-target gland axes were grouped using factor analysis. Then the sensitivity of every indicator was calculated according to the sensitivity function defined in this paper, so as to find all the most sensitive indicators in every group as key indicators of SYDS.</p><p><b>RESULTS</b>The key indicators in the early period of SYDS were T, LH, T4, and CORT. The key indicators in the middle period were LH,T, CORT, and ACTH. The key indicators in the late period were LH, T, CORT, and FSH.</p><p><b>CONCLUSIONS</b>T, LH, and CORT were the common key indicators of the three periods, and other different key indicator of SYDS in the early, middle and late period were T4, ACTH, and FSH respectively, which changed from the thyroid axis to the adrenal axis and then to the gonadal axis as the period changed. The key indicators in the late period were mainly in the gonadal axis, showing gonadal dysfunction in the late period.</p>
