目的:寻找磷酸钙骨水泥/顺铂复合体修复肿瘤性骨缺损的最佳质量构成比.方法:通过原子吸收分光光度法对通过混合-模压法制备的不同质量比构成的磷酸钙骨水泥/顺铂复合体体外缓释液中顺铂浓度进行测定,寻找最合适的磷酸钙骨水泥、顺铂质量构成比,在此基础上制备骨缺损和移植肿瘤动物模型和动物体内进行骨缺损的修复实验和体内抑瘤实验.结果:含0.1%~0.2%顺铂的磷酸钙骨水泥能够修复兔骨缺损,同时又能对肿瘤细胞产生抑制杀伤作用.结论:含0.1%~0.2%顺铂的磷酸钙骨水泥能够消灭残存肿瘤细胞,且最终不影响骨修复的进程.
目的:尋找燐痠鈣骨水泥/順鉑複閤體脩複腫瘤性骨缺損的最佳質量構成比.方法:通過原子吸收分光光度法對通過混閤-模壓法製備的不同質量比構成的燐痠鈣骨水泥/順鉑複閤體體外緩釋液中順鉑濃度進行測定,尋找最閤適的燐痠鈣骨水泥、順鉑質量構成比,在此基礎上製備骨缺損和移植腫瘤動物模型和動物體內進行骨缺損的脩複實驗和體內抑瘤實驗.結果:含0.1%~0.2%順鉑的燐痠鈣骨水泥能夠脩複兔骨缺損,同時又能對腫瘤細胞產生抑製殺傷作用.結論:含0.1%~0.2%順鉑的燐痠鈣骨水泥能夠消滅殘存腫瘤細胞,且最終不影響骨脩複的進程.

Objective To explore the best mass ratio of calcium phosphate cement (CPC) / cisplatin complex filling and to repair bone defect caused by tumor resection. Methods Mixed-molding method was used to obtain cisplatin/calcium phosphate cement complex at 0, 0.1%, 0.2%, and 0.4% mass ratio. Drug concentration was determined by atomic absorption spectrophotometry. Bone defect of rabbits and osteosarcoma of rats were prepared. We implanted CPC and CPC/cisplatin complex to observe the repair of bone defect and the inhibition of tumor in vivo. Results CPC containing 0.1% ~ 0. 2 % cisplatin not only repaired the bone defect in rabbits but also eliminated osteosarcoma in rats. Conclusion CPC containing 0.1% ~ 0. 2 % cisplatin can repair bone defect and eliminate tumor without influencing the prosthetic precess.
