恶性肿瘤的发病率呈逐年上升的趋势,其严重危害人类的健康。目前,临床上应用的传统抗肿瘤药物存在靶向性差,细胞毒性强,患者不易耐受的缺点。因此,提高抗肿瘤药物的靶向性、减轻药物的不良反廊已成为抗肿瘤药物新型给药系统研究的热点方向。随着肿瘤分子水平研究的不断深入,发现某 The incidence of malignant tumors showed a rising trend year by year, which seriously endanger human health. Currently, the clinical application of traditional anticancer drugs have poor targeting, strong cytotoxicity, the patient is not easy to tolerate the shortcomings. Therefore, to improve the targeting of anti-tumor drugs and to reduce the adverse anti-tumor drugs has become a new drug delivery system for antitumor research hot spots. With the deepening of the study of tumor molecular levels, found that
