患恶性肿瘤者约有80％需要化疗,然而化疗在杀伤肿瘤细胞的同时,对正常细胞如胃肠黏膜上皮等都会造成影响,并且在出现疗效的同时常伴有不同程度的毒性反应,往往使一部分患者难以接受预期的治疗,甚至产生恐惧心理,从而影响疗效。 多数化疗药物作用于中枢神经系统,并且对增殖旺盛的胃肠黏膜上皮有抑制作用,患者应用后常有食欲减退、恶心、呕吐、腹泻、腹痛等胃肠道反应。现代医学研究认为,造成胃肠道反应的原因有以下 About 80% of people with malignant tumors need chemotherapy. However, chemotherapy kills tumor cells and affects normal cells, such as gastrointestinal mucosal epithelium. At the same time, there are often different degrees of toxicity in response to chemotherapy. Some patients are difficult to receive the desired treatment, and even produce fear, which affects the efficacy. Most chemotherapeutic drugs act on the central nervous system and have an inhibitory effect on proliferating gastrointestinal mucosal epithelium. Patients often suffer from loss of appetite, nausea, vomiting, diarrhea, abdominal pain, and other gastrointestinal reactions. Modern medical research believes that the causes of gastrointestinal reactions are the following
