生长抑素是一种具有广泛生物学活性的物质 ,它对神经内分泌肿瘤有较强的抑制作用。近年来 ,它对其它实体肿瘤的抑制作用已引起人们的关注。生长抑素的人工合成类似物 ,对肿瘤有较强的抑制作用。其机制可能是通过生长抑制激素受体的介导 ,降低某些生长激素和细胞因子水平 ,从而诱导细胞凋亡 ,调节肿瘤周围血管系统和提高机体免疫力等有关。 Somatostatin is a substance with a wide range of biological activity, it has a strong inhibitory effect on neuroendocrine tumors. In recent years, its inhibitory effect on other solid tumors has drawn people’s attention. Somatostatin synthetic analogues, the tumor has a strong inhibitory effect. The mechanism may be through the growth inhibition of hormone receptor-mediated reduction of certain growth hormone and cytokine levels, thereby inducing apoptosis, regulating the tumor surrounding vascular system and improve the body immunity and so on.
