癌细胞的一个特点就是生长迅速,不停地分裂,快速增长。所以设计抗癌药的时候,这些传统抗癌药都被设计成特异性地攻击快速生长的细胞,以期望只杀死癌细胞,而不对通常生长缓慢的大多数细胞带来伤害。可是,我们的人体偏偏就有一些细胞正常情况下也是生长快速,更新换代很快。比如,骨髓细胞、发囊细胞、口腔黏膜细胞、消化道上皮细胞、女性生殖道细胞,等等。传统化疗药物从静脉注射入体内后,很快遍布全身,杀灭癌细胞的同时,也就无差异地攻击这些生长迅速的细胞,所以常见的副作用就出现了,这其 One of the characteristics of cancer cells is rapid growth, constantly splitting, rapid growth. Therefore, when designing anticancer drugs, these traditional anticancer drugs are all designed to specifically attack rapidly growing cells in the hope of killing only the cancerous cells without damaging most cells, which usually grow slowly. However, our body happens to have some cells under normal circumstances, rapid growth, rapid replacement. For example, bone marrow cells, hair follicle cells, oral mucosal cells, gastrointestinal epithelial cells, female reproductive tract cells, and so on. Traditional chemotherapy drugs from the intravenous injection into the body, quickly spread throughout the body, kill cancer cells, but also indiscriminately attack these rapidly growing cells, so the common side effects appeared
