益气化瘀解毒方及其单味药对人肝癌HepG2裸鼠移植瘤血管拟态相关因子的影响

Effect of Yiqi Huayu Jiedu Prescription on the Growth of HepG2 Nude Mice Transplantation Tumor and the Expression of Related Factors of Vascular Mimicry

目的探讨益气化瘀解毒方及其单味药对人肝癌移植瘤血管拟态相关因子表达的影响。方法瘤细胞接种建立人肝癌移植瘤模型,随机分为益气化瘀解毒方组(全方组)、黄芪组、莪术组、重楼组、壁虎组、顺铂组及模型组,除模型组外,各给药组予相应药物干预。21d后,采用免疫组化法检测瘤组织低氧诱导因子-1α(HIF-1α)、基质金属蛋白酶(MMP)-9、MMP-2、E-钙黏附蛋白(E-cad)表达,免疫荧光法观察血管生成拟态结构,实时荧光定量PCR检测瘤组织Twist1、Bcl-2表达。结果与模型组比较,给药后各给药组瘤体积减小(P<0.05),全方组优于黄芪组、重楼组、壁虎组(P<0.05);各组血管生成拟态结构荧光表达稀少,模型组、顺铂组最为明显;除黄芪组外,各给药组HIF-1α及MMP-9、MMP-2表达与模型组比较差异有统计学意义(P<0.05),全方组最为明显;全方组、黄芪组E-cad表达与模型组比较差异有统计学意义(P<0.05);全方组、重楼组、壁虎组与模型组比较Bcl-2表达明显降低(P<0.05),其中全方组Bcl-2表达明显优于其他给药组(P<0.05);全方组、莪术组、重楼组、顺铂组Twist1表达与模型组比较差异有统计学意义(P<0.05)。结论益气化瘀解毒方及其单味药通过下调HIF-1α、Twist1、Bcl-2、MMP-2、MMP-9及上调E-cad表达,从而抑制血管生成拟态形成。

Objective To observe the influencing of Yiqi Huayu Jiedu Prescription on the growth of HepG2 nude mice transplantation tumor and the expression of related factors of vascular mimicry. Methods Models of transplanted tumors, which were made by HepG2 cells in nude mice, were randomly divided into 7 groups, Yiqi Huayu Jiedu Prescription group, Astragali Radix group, Curcumae Rhizoma group, Paridis Rhizoma group, Gecko group, cis-platinum group, and model group. Except for the model group, the rest groups were given relevant medicine for intervention. 21 days later. HIF-1α, MMP-2, MMP-9, and E-cad were detected by immunohistochemistry, and Twist1 and Bcl-2 were detected by fluorescence quantitative PCR. Results Compared with the model group, tumor volume in the rest groups decreased (P<0.05), and the effect in the Yiqi Huayu Jiedu Prescription group was more obvious than the Astragali Radix group, Paridis Rhizoma group and Gecko group (P<0.05);The expression of vasculogenic mimicry structure was rare in each group, and the model group and cis-platinum group were the most obvious;Except for the Astragali Radix group, the expressions of HIF-1α, MMP-2, and MMP-9 showed statistical significance compared with model group (P<0.05);The expression of E-cad in the Yiqi Huayu Jiedu Prescription group and Astragali Radix group showed statistical significance (P<0.05);The expression of Bcl-2 in the Yiqi Huayu Jiedu prescription group, Paridis Rhizoma group, and Gecko group decreased significantly compared with the model group (P<0.05);The expression of Bcl-2 in the Yiqi Huayu Jiedu prescription group was much better than the other groups (P<0.05);The expression of Twist1 showed statistical significance in the Yiqi Huayu Jiedu Prescription group, Curcumae Rhizoma group, Paridis Rhizoma group, and cis-platinum group (P<0.05). Conclusion Yiqi Huayu Jiedu Prescription can reduce expression of HIF-1α, Twist1, Bcl-2, MMP-2, and MMP-9, and increase expression of E-cad, thereby inhibiting the formation of vascular mimicry.
