From this study, both low hCG and high hCG are adversity to pregnancy, hCG level reflect the growth and function situation of trophocyte which is the main component of placenta, whereas, the level of steroid hormone which close to hCG directly influence whether pregnancy will maintain, but in some cases being short of oxygen in uterine placenta local, usually display hCG level higher than normal pregnancy.

在正常妊娠时hCG过低往往预示着流产的可能，从本研究结果看，可能不仅仅是hCG水平过低对妊娠不利，hCG水平很高对妊娠也不利。hCG水平的高低反映了作为胎盘主要组份的滋养细胞的生长情况与功能，而与hCG水平高低密切相关的类固醇激素的高低直接影响了妊娠能否持续下去。

Carps were fed on basal diets with additive cysteamine at different levels of 0, 200, 400, 600 and 800 mg/kg for 42 days respectively to investigate the effects of cysteamine on carp's growth and the levels of relevant hormone and biochemical indexes of blood.

在鲤鱼基础饵料中分别添加0、200、400、600和800mg/kg的半胱胺，经过42d的饲养试验，研究不同水平的半胱胺对鲤鱼生长、相关激素水平、血清生化指标的影响。

Itamin D from the skin and diet is metabolized in the lier to 25-hydroxyitamin D (Figure 1), which is used to determine a patient's itamin D status1,2,3,4; 25-hydroxyitamin D is metabolized in the kidneys by the enzyme 25-hydroxyitamin D-1-hydroxylase (CYP27B1) to its actie form, 1,25-dihydroxyitamin D.1,2,3,4 The renal production of 1,25-dihydroxyitamin D is tightly regulated by plasma parathyroid hormone leels and serum calcium and phosphorus leels.1,2,3,4 Fibroblast growth factor 23, secreted from the bone, causes the sodium–phosphate cotransporter to be internalized by the cells of the kidney and small intestine and also suppresses 1,25-dihydroxyitamin D synthesis.5 The efficiency of the absorption of renal calcium and of intestinal calcium and phosphorus is increased in the presence of 1,25-dihydroxyitamin D (Figure 1).2,3,6 It also induces the expression of the enzyme 25-hydroxyitamin D-24-hydroxylase (CYP24), which catabolizes both 25-hydroxyitamin D and 1,25-dihydroxyitamin D into biologically inactie, water-soluble calcitroic acid.2,3,4

从皮肤和食物来的维生素D在肝中代谢为25-羟基维生素D（图1），被用来决定病人体内维生素D情况的1，2，3，4；25-羟基维生素D在肾中被25-羟基维生素D1羟化酶（CYP27B1）转变为有活性的1，25-二羟基维生素D 。1，2，3，4由肾产生1，25-二羟基维生素D是被血浆甲状旁腺激素和血清钙，磷水平紧密调节。1，2，3，4由骨分泌的成纤维细胞生长因子23使钠磷协同转运蛋白被肾和小肠细胞内化及抑制1，25-二羟维生素D合成。5 在1，25-二羟基维生素D作用下肾和小肠吸收钙及磷的效率增高(图1)。2，3，6 它也包括25-羟四- 24 -羟化酶的表达(CYP24)，且将1，25二羟基维生素D和25羟基维生素D异化成无生物活性，水溶性的维生素D3-23羧酸。2，3，4

ObjectiveTo gain insight into the mechanism of iodine and thyroid hormone action in brain development. We have observed the difference of cerebellar morphology between iodine deficient dam rats and the normal ones and have tested whether congenital iodine deficiency could regulate immediate early gene proteins c -fos, c - jun and growth - associated protein - 43 ( GAP - 43) in pup cerebellums.
