摘要

目的: 研究六君祛痰解毒汤及其拆方对小鼠Lewis肺癌转移的抑制作用及作用机制。方法: 建立C57BL/6J小鼠Lewis肺癌转移模型

随机分为对照组、替加氟阳性对照组(78 mg·kg-1)、六君祛痰解毒汤(21 g·kg-1)及拆方六君祛痰汤(11 g·kg-1)、解毒汤(10 g·kg-1)和祛痰汤(5 g·kg-1)6组。ig给药15 d后剥瘤称取瘤质量

计算抑瘤率;摘取肺组织

固定后于解剖显微镜下观察肺表面转移灶数

计算肺癌转移率和抗转移率;用免疫组化和图像分析方法检测瘤组织细胞中CD44的表达;用放射免疫法检测血清中透明质酸(HA)及Ⅳ型胶原(Col Ⅳ)的含量。结果: 各治疗组皆可抑制小鼠Lewis肺癌移植瘤的生长

肺癌转移灶明显减少

以六君祛痰解毒汤效果最好。给药各组皆程度不同地抑制小鼠移植瘤细胞CD44的表达

与模型对照组比较

六君祛痰解毒汤具有显著性差异(P<0.05)

六君祛痰汤及祛痰汤具有极显著性差异(P<0.01);4个治疗组皆能降低荷瘤小鼠血清HA和Col Ⅳ的含量

六君祛痰汤的效果最好

六君祛痰解毒汤和祛痰汤次之(P<0.01)

而解毒汤的作用则相对较弱。结论: 六君祛痰解毒汤及其拆方对Lewis肺癌转移模型小鼠具有抗肿瘤转移作用

其机制可能与抑制肿瘤细胞对细胞外基质(ECM)的破坏、使其血清中HA和Col Ⅳ水平降低

下调肿瘤细胞CD44的表达、降低其与基质的黏附

进而抑制肿瘤细胞的运动、侵袭和转移有关。

Abstract

Objective: To study the anti-metastasis effect and mechanism of Liujun Qutan Jiedu decoction and its functional groups in metastasis of C57 BL/6J mice Lewis lung cancer. Method: The Lewis lung metastasis model was established in C57 BL/6J mice

randomly divided into 6 groups: saline model group

Tegafur positive control group (78 mg·kg-1)

Liujun Qutan Jiedu decoction (21 g·kg-1)

Liujun Qutan decoction (11 g·kg-1)

Jiedu decoction (10 g·kg-1)and Qutan decoction (5 g·kg-1).After oral administration for 16 days

the tumor was stripped and weighed to calculate the inhibition rate.The metastatic tumor foci on lung surface in mice were counted to calculate the rate of cancerometastasis and anti-metastasis.Expression of CD44 in tumor cells was measured by immunohistochemistry and image analysis system

the concentrations of serum hyaluronic acid(HA) and collagen Ⅳ(Col Ⅳ) were detected by radioimmunoassay. Result: Liujun Qutan Jiedu decoction and its functional groups could inhibit the metastasis of Lewis lung carcinoma.The metastatic foci occurrence rates of treatment groups on lung surface were lower than model group.The effect of Liujun Qutan Jiedu decoction was the best.All treatment groups can inhibit the expression of CD44 to some degree.Compared with the model group

Liujun Qutan Jiedu decoction had a significant difference(P<0.05)

Liujun Qutan decoction and Qutan decoction had a more significant difference(P<0.01);All four treatment groups could reduce the concentrations of serum HA and Col Ⅳ

however

the effect of Liujun Qutan decoction was the best

the effect of Liujun Qutan Jiedu decoction and Qutan decoction were the second(P<0.01)

and the function of Jiedu decoction was relatively weak. Conclusion: Liujun Qutan Jiedu decoction and its functional groups all have anti-metastasis activities on Lewis lung metastasis model in C57BL/6J mice

and the underlying mechanisms were possibly related to inhibiting the breaking of extracellular matrix(ECM) caused by tumor cells

reducing the concentrations of serum HA and Col Ⅳ.At the same time

the mechanism also related to inhibiting tumor cells moving

attacking and transferring by reducing the expression of CD44 and its adhesion to ECM.
