目的:探讨超声引导下复方中药艾迪注射液瘤内注射治疗兔移植性VX2肝肿瘤的作用效果及机制。方法建立新西兰大白兔肝VX2移植性肿瘤模型28只,随机分为3组,即艾迪注射液局部注射治疗组(12只)、经皮无水乙醇注射(percutaneous ethanol injection ,PEI)组(8只)、生理盐水局部注射治疗组(8只)。全部动物在接种2周后每隔3天向肿瘤内注入治疗药物,4次后处死。于术前术后兔耳缘静脉抽血行血生化检查,同时行64排螺旋C T 扫描测量并计算肿瘤体积、肿瘤增长率及肿瘤坏死率,以及进行免疫学、组织细胞学与细胞超微结构的观察。结果各实验组病灶均进行性增大,但艾迪注射液治疗组肿瘤增长率及坏死率最小,与生理盐水组比较差异均有统计学意义( P <0.05),与无水乙醇治疗组比较差异无统计学意义;艾迪注射液治疗组血管内皮生长因子(vascular endothelial growth factor ,VEGF)蛋白表达水平最低,低于无水乙醇治疗组和生理盐水组,有显著差异性( P <0.05);同时,艾迪注射液治疗组有1例出现肝内转移灶,而无水乙醇及生理盐水治疗组分别有4例和5例出现转移灶,有显著差异性( P <0.05);艾迪注射液治疗组AST 、ALT、ALP、BUN及白细胞计数治疗前后均无明显差异,组内及组间比较无统计学意义( P >0.05)。结论艾迪注射液能明显抑制兔肝移植性VX2肿瘤VEGF蛋白的表达。
目的:探討超聲引導下複方中藥艾迪註射液瘤內註射治療兔移植性VX2肝腫瘤的作用效果及機製。方法建立新西蘭大白兔肝VX2移植性腫瘤模型28隻,隨機分為3組,即艾迪註射液跼部註射治療組(12隻)、經皮無水乙醇註射(percutaneous ethanol injection ,PEI)組(8隻)、生理鹽水跼部註射治療組(8隻)。全部動物在接種2週後每隔3天嚮腫瘤內註入治療藥物,4次後處死。于術前術後兔耳緣靜脈抽血行血生化檢查,同時行64排螺鏇C T 掃描測量併計算腫瘤體積、腫瘤增長率及腫瘤壞死率,以及進行免疫學、組織細胞學與細胞超微結構的觀察。結果各實驗組病竈均進行性增大,但艾迪註射液治療組腫瘤增長率及壞死率最小,與生理鹽水組比較差異均有統計學意義( P <0.05),與無水乙醇治療組比較差異無統計學意義;艾迪註射液治療組血管內皮生長因子(vascular endothelial growth factor ,VEGF)蛋白錶達水平最低,低于無水乙醇治療組和生理鹽水組,有顯著差異性( P <0.05);同時,艾迪註射液治療組有1例齣現肝內轉移竈,而無水乙醇及生理鹽水治療組分彆有4例和5例齣現轉移竈,有顯著差異性( P <0.05);艾迪註射液治療組AST 、ALT、ALP、BUN及白細胞計數治療前後均無明顯差異,組內及組間比較無統計學意義( P >0.05)。結論艾迪註射液能明顯抑製兔肝移植性VX2腫瘤VEGF蛋白的錶達。

Objective To explore the principle ,effect and method of percutaneous AiDi injection for tumor ablation . Methods Twenty-eight new zealand white rabbits with implanted liver VX2 tumors were randomly divided into three groups:AiDi injection group (n=12) ,percutaneous ethanol injection (PEI) group (n=8) ,and physiological saline group (n=8) .Three weeks after transplantation ,the drugs were injected into tumors of all the rabbits once every 3 days .After 4 times injection ,the rabbits were killed .The tumors were measured 3 dimensionally with CT ,while the rates of tumor necrosis ,the volume of tumor and the growth rate of the tumor were calculated .Liver and kidney function tests (AST , ALT ,ALP and BUN) as well as white blood cell counts were assessed before and after treatment ,and CT examination was performed at the same time .The morphological and the ultramicrostructural changes were also investigated under light mi-croscope or electron microscope .Vascular endothelial growth factor (VEGF) and expression were examined by immuno-histochemistry .Results Tumors in all groups kept growing after the procedure .Among all 3 groups ,tumor growing rate for AiDi injection group was the lowest and the necrotic rate was the highest ( P <0 .05) ,while no significant difference was found between AiDi injection group and PEI group ( P > 0 .05) .There was no evident change of liver and kidney function before and after treatment in the 3 groups ( P>0 .05) .The expression of VEGF protein was statistically lowest of the AiDi injection group ( P<0 .05) .The expression of VEGF protein in the PEI group was lower than that of the sa-line group .Conclusion AiDi injection can inhibite the expression of VEGF of in the liver VX 2 tumors tissue .
