有关儿童生长生理影响儿童生长的激素可归为两大类,一类包括甲状腺激素、性激素、皮质类固醇等激素,此类激素对生长起允许作用;另一类为生长激素(GH),可以直接刺激生长,其作用是依赖剂量的。人体的生长分为三个阶段。第一阶段是2～3岁前,此期生长迅速,不需GH的作用;第二阶段为4岁至青春期前,此期生长速率保持稳定,非常依赖GH;第三阶段为青春期后,此时的生长同时依赖GH与性激素。关于GH影响生长有以下四种情况:(1)GH分泌速度。(2)GH分泌形式。(3)周围组织对GH的反应。(4)GH的不均一性。GH分 Hormones that affect the growth of a child’s physiology can be grouped into two broad categories, one that includes hormones such as thyroid hormones, sex hormones, and corticosteroids, which allow for growth; the other is growth hormone (GH) Stimulate growth, its role is dependent on the dose. The growth of the human body is divided into three stages. The first stage is 2 to 3 years old, this period of rapid growth, without the role of GH; the second stage of 4 years to pre-puberty, the growth rate remained stable, very dependent on GH; the third stage after puberty, this Growth depends on both GH and sex hormones. GH on the growth of the following four situations: (1) GH secretion rate. (2) GH secretion form. (3) the response of surrounding tissues to GH. (4) Inhomogeneity of GH. GH points
