摘 要 目的 研究银杏黄酮苷元(GA)对多柔比星(DOX)治疗肝癌的增效减毒作用。方法 于ICR小鼠右腋皮下单次接种肝癌细
胞H22以建立荷瘤模型,并将造模成功的小鼠随机分为模型对照组、DOX组(2.5 mg/kg,隔天尾静脉注射1次)、GA组(30 mg/kg,
每天灌胃1次)和GA+DOX组(给药方法同单药组),每组6只。药物干预周期为15 d。观察各组小鼠的一般生长情况,称定其体
质量、瘤体质量并计算抑瘤率,采用金氏公式评估联合用药的效果(Q)。检测各组小鼠血清中甲胎蛋白(AFP)水平,肿瘤组织的病
理改变、细胞凋亡情况和血小板-内皮细胞黏附分子1(CD31)的表达水平,以及心脏指数、血清B型钠尿肽(BNP)和N末端脑钠肽
前体(NT-pro BNP)水平、心脏病理改变和心肌纤维化情况。结果 DOX组、GA组、GA+DOX组小鼠的体质量变化百分比(GA组除
外)、瘤体质量均较模型对照组显著降低(P<0.05或P<0.01),且GA+DOX组的瘤体质量显著低于DOX组(P<0.01);3个药物组
的抑瘤率分别为54.29%、42.50%、89.29%,两药联合的Q为1.21。各药物组小鼠肿瘤组织均有不同程度坏死,血清AFP水平和肿
瘤组织中CD31的表达水平均较模型对照组显著降低(P<0.05或P<0.01),肿瘤组织坏死面积百分比和细胞凋亡阳性率(单药组
除外)均显著增高(P<0.05或P<0.01),且GA+DOX组的细胞凋亡阳性率显著高于DOX组(P<0.05)。DOX组小鼠的心脏指数
显著低于模型对照组(P<0.05),DOX组、GA+DOX组小鼠的血清BNP、NT-pro BNP水平均显著高于模型对照组(P<0.05或P<

ABSTRACT OBJECTIVE To study the effects of increasing efficacy and decreasing toxicity of ginkgo flavone aglycone(GA)
on doxorubicin(DOX)in the treatment of liver cancer. METHODS A tumor bearing model was established by inoculating liver
cancer cell H22 into the right axillary skin of ICR mice. The successfully modeled mice were randomly divided into model control
group,DOX group(2.5 mg/kg,once every other day,via tail vein),GA group(30 mg/kg,once a day,gavage)and GA+DOX
group(the usage was the same as single drug groups),with 6 mice in each group. The administration cycle was 15 days. The
general growth of mice in each group were observed,body weight and tumor weight were measured,and the inhibition rate of
tumor was calculated. Jin’s formula was used to evaluate the effect of combined medication(Q). The serum level of alpha-fetal
protein(AFP),the pathological changes of tumor tissue,cell apoptosis and the expression of platelet-endothelial cell adhesion
molecule-1(CD31)were detected in each group. The cardiac
