摘　　要：目的观察盐酸多柔比星脂质体联合碘化油用于栓塞肝动脉治疗兔VX2肝癌的药代动力学及药效学表现。方法分别按1∶1、1∶2及2∶1比例配制盐酸多柔比星脂质体-碘化油混悬液,观察其分层时间。将20只健康新西兰大白兔随机均分为A~D组(各5只),对A组经导管注入盐酸多柔比星脂质体-碘化油乳剂、B组注入盐酸多柔比星-碘化油乳剂以栓塞肝动脉,对C组予盐酸多柔比星脂质体、D组予盐酸多柔比星行肝动脉灌注化疗。比较处置后4组1、4、8、12、16、20及24 h血药浓度。以另外20只健康新西兰大白兔建立VX2肝癌模型,并将其随机均分为实验组与对照组(各10只),对实验组经导管注入盐酸多柔比星脂质体-碘化油乳剂、对照组注入多柔比星-碘化油乳剂以栓塞肝动脉;根据改良实体瘤疗效评价标准(mRECIST)评估疗效,记录肿瘤客观缓解率(ORR)及疾病控制率(DCR)。结果不同比例盐酸多柔比星脂质体-碘化油混悬液均于1 min内出现分层。药代动力学实验显示,A、C组处置后各时间点血药浓度相近,且均高于B、D组。药效学实验显示,实验组肿瘤ORR及DCR分别为50.00%(5/10)及90.00%(9/10),对照组分别为40.00%(4/10)及80.00%(8/10)。结论以盐酸多柔比星脂质体-碘化油乳剂行肝动脉栓塞与单纯灌注化疗后各时间点血药浓度相近;前者用于栓塞治疗兔VX2肝癌效果与多柔比星-碘化油乳剂相当。Objective To observe the pharmacokinetics and pharmacodynamics of doxorubicin hydrochloride liposomes combined with iodized oil in hepatic artery embolization of rabbit VX2 liver cancer.Methods Doxorubicin hydrochloride liposomes-lipiodol suspension were prepared at ratios of 1∶1,1∶2 and 2∶1,respectively,and the delamination time of each suspension was observed.Twenty New Zealand white rabbits were randomly divided into group A—D(each n=5).Doxorubicin hydrochloride liposomes-iodized oil emulsion was injected into group A,while doxorubicin hydrochloride-iodized oil emulsion was injected into group B for embolization of hepatic artery.Hepatic artery infusion was performed in group C with doxorubicin hydrochloride liposomes,while in group D with doxorubicin hydrochloride.The blood drug concentrations 1,4,8,12,16,20 and 24 h after treatments were compared among 4 groups.Another 20 healthy New Zealand white rabbits were modeling,and the rabbit models of VX2 liver cancer were randomly divided into experimental group and control group(each n=10).Doxorubicin hydrochloride liposomes-iodized oil emulsion was used in experimental group,while doxorubicin-iodized oil emulsion was used in control group for embolization of hepatic artery.The therapeutic effect was evaluated according to modified response evaluation criteria in solid tumors(mRECIST),and the objective response rate(ORR)and disease control rate(DCR)were recorded.Results Doxorubicin hydrochloride liposomes-lipiodol suspension with different proportions were all stratified within 1 min.Pharmacokinetic experiment showed that the blood drug concentration of group A and C were similar at each time point after treatment,and both higher than that in group B and D.Pharmacodynamics experiments showed that ORR and DCR in experimental group was 50.00%(5/10)and 90.00%(9/10),respectively,while in control group was 40.00%(4/10)and 80.00%(8/10),respectively.Conclusion Blood drug concentrations of doxorubicin hydrochloride were similar at each time point after hepatic art
