从IRC结果以及对过渡态结构的电子密度拓扑学分析结果可以确定，羟基自由基在反应过程之中抽取了黄酮类化合物A环上未参与分子内氢键结构的酚羟基上的氢原子形成水分子及稳定性更高的半醌式大环自由基，在整个过程之中羟基自由基从反应物一侧进攻并逐渐发生扭转，直至形成一个进平面结构的过渡态结构，这与上一章关于黄酮类化合物B环的研究结果基本一致。

Results After suppression of1mg dexamethasone,the plasma cortisol of all patients with Cushing's syndrome were more than1.8μg/dl,and94.6%patients'more than5μg/dl.Several kinds of diagnostic standards were good when used for2mg dexamethasone suppression test in Cushing's syndrome,a-mong them,the standard for urine free cortisol after suppression should be adjusted to50%of the contrast and the as-sayed data should in normal limits.Low dose dexamethasone suppression tests were not satisfied when used among the patients with some situations needed to differentiate with Cushing's syndrome.Suppressed by8mg dexamethasone could direct the diagnose of Cushing's disease（97.0%）,though17.7%of this kind of patients could not be sup-pressed;it was not suppressed in other etiological diseases（93.4%）Conclusion The results of dexamethasone sup-pression tests were match the clinical examination.

结果 所有库欣综合征病人在1mg地塞米松抑制后血皮质醇大于1.8μg/dl，94.6%的病人大于5μg/dl；2mg地塞米松抑制后多种诊断标准在库欣综合征病人中均较好，其中尿游离皮质醇抑制后诊断标准应调整为对照值的50%并在正常范围内；小剂量地塞米松抑制试验对类库欣情况鉴别均较差；8mg地塞米松试验能抑制的病人基本可诊断为库欣病（准确性97.0%），但有17.7%的病人不抑制，其他病因的库欣综合征基本不抑制（准确性93.4%）。
