目的探讨和分析肿瘤靶向物载体的细胞靶向性。方法 选择293T细胞和H460细胞作为实验标本，实验地点选择该院实验室，时间为2016年2—3月，选择合成的SP5-52、阿霉素、第4代聚酰胺—胺、超滤离心管、荧光分子异硫氰酸荧光素等，并总结和探讨肿瘤靶向性药物所具有的细胞靶向性。结果 在常规药物制剂的条件下对抗肿瘤药物新型靶向载体系统进行发展，并且改善药物在载体内部的代谢动力学相关特征，能够让药物向富集到肿瘤药部位、肿瘤细胞内部聚集，保证疗效得到提升，毒副作用逐渐减小，检测浓度范围之内细胞存活率超过80%，其中G4-Ac毒性为90%、G4-Ac-FITC为87%、而G4-Ac-FITC-SP5-52细胞毒性为97%，差异具有统计学意义（P＜0.05）。结论 在科学技术不断发展和进步的影响下，抗癌药物剂型的研究工作开始朝着靶向、高效、智能化方向发展，理想药物剂型具有控释、缓释、靶向发展前景较为广阔，值得在；临床运用上进行使用和推广。

［Abstract］Objective To investigate and analyze the cell targeting of tumor targeting vector.Methods Source selection to 293T cells and H460 cells as experimental samples，experimental sites were selected in the laboratory of our hospital for February 2016 to 2016 March，SP5 52，doxorubicin，the 4th generation of polyamide amine，ultra filtration centrifuge tube，fluorescence isothiocyanate fluorescein，and summarize and discuss the tumor target to drugs with cell targeting.Results U-under the conditions of conventional pharmaceutical formulations against tumor new drug target to support system development，and improve the drug in the carrier of metabolic dynamics characteristics，can make the drug to enriched to drug site of tumors and tumor cells aggregation，ensure curative effect to improve，toxic side effect decreases gradually，detection concentration range cell survival rate of over 80%，which G4-Ac toxicity is 90%，G4-Ac-FITC as 87%，and G4-Ac-FITC-SP5 52 cytotoxicity was 97%；the difference is statistically significant（P＜0.05）.Conclusion Under the influence of the continuous development of science and technology and progress，form of anticancer drugs work started towards the target，efficient，intelligent direction，ideal of pharmaceutical dosage forms with controlled and sustained release，targeted development prospect is broad，it is in；clinical application of use and promotion.

很多治疗以及诊断肿瘤的药物在临床上的运用较为普遍，这些药物所产生的作用具有显著的非选择性特征，体内分布相对较广，一些正常组织器官有着较多的分布在，治疗剂量下对于正常组织器官的毒副作用较为明显，患者无法耐受，从而导致质量效果受到影响［1］。如何提升抗肿瘤药物治疗效果，首先要能够保证药物的肿瘤选择性得到提升，降低在非靶部位出现聚集的现象，减少药物对非靶部位产生的毒副作用，在降低药物治疗剂量的同时减少不必要的给药次数，提升药物效果［2］。……
