碘的

Experimental research on the effect of iodine excess on thyroid function in animal is divided into two aspects: the effect of iodine excess on thyroid function in autoimmune thyroid disease susceptible animal and the effect of iodine excess on thyroid function in common animal.

碘过量对甲状腺功能影响的动物实验研究分为两方面，碘过量对自身免疫病易感动物甲状腺功能的影响和碘过量对普通动物甲状腺功能的影响。

The chapter two was focused on the samarium diiodide promoted organic reactions and their applications in organic synthesis, firstly, a new synthesis of highly substituted cyclopentadienes from a,β-alkynone promoted by samarium diiodide was investigated and the highly substituted cyclopentadienes were prepared in moderate to good yields under mild conditions. Secondly, the Michael addition and Michael-aldol tandem reaction of diorganyl diselenides or diorganyl disulfides with α,β-alkynones mediated by samarium diiodide were studied and a series of alkenylsulfides and alkenylselenides were prepared in good yields. Then the highly regioselecfive nucleophilic addition of the allylsamarium bromide to α,β-alkynones were explored. We found that the allylsamarium bromide reacts with α,β-alkynones to afford regiospecificly 1. 2-nucleophilic addition products in good yields under mild condition. At last we studied the coupling reaction of aryl halides promoted by NiCl〓/PPh〓/Sm〓.

The purpose of this study was to investigate the iodine nutrition and the epidemiologic state of hyperthyroidism in ChongQing after universal salt iodization .

因此，加强对人群碘摄入量的监测，及时调整食盐碘含量，使碘摄入量维持在安全剂量范围内具有重大的意义。

Methods To select who lived in iodine sufficient area which was taken salt iodization program to regard as research target in the assignment for study.

Methods: 141 healthy subjects and 144 patients with thyrocele and hyperthyroidism were randomly choosed from the outpatient department of the First Affiliated Hospital of ChongQing University of Medical Sciences and ChongQing University.

第一部分目的：通过对正常成人和甲状腺肿伴甲亢患者的尿碘对比分析，掌握食盐加碘后重庆市区正常成人和甲状腺肿伴甲亢患者的碘营养状况。

The iodine deficiency was corrected by the supplementation of iodized salt,however ,higher and lower intake of iodine all existed among the patients with thyrocele and hyperthyroidism .

合理补充碘盐能够纠正重庆市居民的碘缺乏状态，目前重庆市处于低碘性甲状腺肿伴甲亢和高碘性甲状腺肿伴甲亢的并存状态。

Results: The mean UI in Chongqing district were higher than proper iodide standard defined by international Council for control of iodine deficiency disorders,and the UI in HT groups were significantly increased compared with Con(P.05). The thyrocele and ophthalmopathy in AITD became more and severer accompanying UI increasing, the rate of goiter and endocrine ophthalmopathy in high iodide AITD was significantly higher than PI AITD( P.05).In the meantime, the positive percentage of TGAb and TPOAb also increased evidently in HI compared with PI(P.05).Cytokine IL-1?

结果：三组患者的平均UI水平高于国际碘缺乏理事会规定的适碘范围，HT患者的UI水平较正常人显著升高（P.05）；在AITD患者UI水平的升高伴随着甲状腺肿大、眼部并发症等临床症状的加重，高碘组与适碘组相比差异有显著性（P.05），且随着UI水平的提高，TGAb和TPOAb阳性百分率明显提高，不同UI水平各组间和每两组间有显著差异(P.05)。
