However, the mechanism underlying the effect ofiodine excess on thyroid function remains unknown in part. Moreover, differentanimals show different ability to respond to iodine deficiency and iodine excess.Therefore, it is of great necessary to establish different animal models in vitro andtake a thorough evaluation of the impact of iodine intakes on thyroid function and itspossible regulation mechanism.

迄今的研究多集中于碘摄入水平与甲功关系这一现象的观察，对碘与甲状腺功能变化的剂量-效应关系及其具体调控机制的实验论证尚有待于进一步深入，且不同动物对碘缺乏与碘过量的反应性和耐受性有所不同，因此有必要建立不同的动物模型，就碘对甲状腺功能的影响及其可能的调控机制做系统而深入的研究。

Contrast-enhanced Ultrasound(1) Renal occupied lesions: the contrast-enhanced imaging feature of renal cell carcinomas are multiformity. It was different in time of start-enhancing and start- expurgation and intensio.3 cases revealed wash-in contemporarily and 6 cases revealed wash- in quickly in time of start-enh ancing.In time of start-expurgating, 3 cases showed wash-out quickly, 3cases revealed wash-out contemporarily,3 cases showed wash-out slowly,6 cases revealed a higher contrast enhancement and 3 cases revealed a even contrast enhancement in enhancing intension; 4 cases with renal cyst s,outline had more clear and inside had no contrast media washing in and enhancing;3cases with renal angiomyolipomas washed in slowly,washed out slowly and equal or low enhanced ; 2cases with renal columnar hypertrophy were no outline appearance and the same enhancement and ech o as the nomal rena tissue.

超声造影诊断结果：(1)肾占位性病变：9例肾透明细胞癌，其超声造影表现多种多样，造影后肾脏恶性病灶造影开始增强的时间、开始廓清的时间及增强强度不等，在开始增强的时间方面，与正常肾皮质同时灌注增强的有3例，表现为快进的有6例，在开始廓清的时间方面，快退3例，同退3例，慢退3例，在增强的强度方面，6例病灶表现为高增强，3例为等增强表现；4例肾囊性病灶，超声造影轮廓较二维超声清晰，但内部始终未见增强；3例肾血管平滑肌脂肪瘤表现为慢进慢退，回声呈等、低增强表现；2例肾柱肥大超声造影无明显包块轮廓出现，造影增强的动态变化时间、强度与正常肾组织一致。

The results show that small world network model could explain the big change of intensiveness and connectedness in forming process. And individual selection value function could explain the stable intensiveness, connectedness in growing and mature process. Combined the both, the characteristics of the whole process could be reflected.

研究表明，小世界网络模型模拟的集群网络具有集群形成期网络整体密集性和连通性剧烈变化的特征，而个体选择价值函数模型可以解释集群网络的成长期、成熟期的密集性和连通性趋于稳定的特征，将2种演化规则相结合，则可以反映集群网络从形成期到成熟期的各生命周期特征。

With the interventional method of the modal called improvisational-structured intervention designed for individual therapy for children with autism in the school for children with mental retardation, three case studies are carried out with the clients of children with autism on different levels, and qualitative and quantitative analyses are used on the results to determine the fitness and value of the modal, the interventional method, and different efforts of different types of music activities used during music sessions.
