| 摘要: |
| 目的 观察131I-牛血清白蛋白（BSA）-聚己内酯（PCL）-索拉非尼（sorafenib）在人甲状腺未分化肿瘤细胞8305C荷瘤裸鼠体内的靶向性分布及其抑瘤作用。方法 制备并鉴定BSA-PCL-sorafenib、131I-BSA-PCL-sorafenib脂质体。12只裸鼠接种人甲状腺未分化肿瘤细胞8305C建立模型，造模成功后分别尾静脉注射生理盐水（对照组）、131I、BSA-PCL-sorafenib和131I-BSA-PCL-sorafenib，通过SPECT/CT显像观察注射后不同时间荷瘤裸鼠体内的放射性分布，比较各组荷瘤裸鼠的体质量及肿瘤质量和体积变化。结果 温育60 min后，131I-BSA-PCL-sorafenib组细胞荧光强度高于对照组。注射22 d后，131I-BSA-PCL-sorafenib组的肿瘤质量和体积最小。结论 131I-BSA-PCL-sorafenib可有效抑制8305C细胞造模诱发的肿瘤生长，在未分化型甲状腺癌的治疗和预后评估中有良好的应用前景。 |

| Abstract: |
| OBJECTIVE To observe the radioactivity distribution and antitumor efficacy of 131I-bovine serum albumin (BSA)-polycaprolactone(PCL)-sorafenib in human anaplastic thyroid carcinoma cells 8305C-bearing nude mouse model. METHODS Prepared and identified BSA-PCL-sorafenib, 131I-BSA-PCL-sorafenib liposomes. Twelve nude mice were inoculated with human anaplastic thyroid carcinoma cells 8305C to establish model. After successful modeling, normal saline (control group), 131I, BSA-PCL-sorafenib, and 131I-BSA-PCL-sorafenib were injected into the tail vein. The radioactivity distribution in tumor-bearing nude mice at different times after injection was observed by SPECT/CT imaging, and the body weight and tumor mass and volume changes of tumor-bearing nude mice in each group were compared. RESULTS After incubation for 60 min, the fluorescence intensity in 131I-BSA-PCL-sorafenib group was higher than that in control group. After injection for 22 d, the weight and volume of tumor in 131I-BSA-PCL-sorafenib group was the smallest one in four groups. CONCLUSION 131I-BSA-PCL-sorafenib can effectively inhibit the tumor growth of 8350C induced-mouse tumor model, which gives a good suggestion for the treatment and prognosis evaluation of anaplastic thyroid carcinoma. |
