2、以5×10/L的A549/DDP接種于裸鼠皮下,待成瘤后,分別給予生理鹽水0.5ml灌胃,0.2ml順鉑腹腔注射同時(shí)生理鹽水灌胃,0.2ml順鉑腹腔注射順鉑和高、中、低劑量的補(bǔ)中益氣湯灌胃。觀察A549/DDP細(xì)胞在各組裸鼠的致瘤率,計(jì)算抑瘤率;采用免疫組化方法、RT—PCR(realtimePCR)檢測(cè)移植瘤組織中PI3K、AKT的表達(dá)水平。結(jié)果補(bǔ)中益氣湯高、中、低劑量組能不同程度的抑制移植瘤的生長(zhǎng),其中以高、中劑量組最顯著,與順鉑組抑瘤率比較有明顯的統(tǒng)計(jì)學(xué)差異(P<0.05);移植瘤中PI3K、AKT蛋白
3、表達(dá)和mRNA基因的表達(dá)在補(bǔ)中益氣湯高、中、低劑量紐中均有下降,高、中劑量組降低較多,與順鉑組和小劑量比較有統(tǒng)計(jì)學(xué)差異(P<0.05)。結(jié)論補(bǔ)中益氣湯聯(lián)合順鉑對(duì)肺腺癌移植瘤的增殖有明顯的抑制作用,補(bǔ)中益氣湯能通過(guò)調(diào)控PI3K、AKT基因和蛋白的表達(dá)而干預(yù)順鉑的耐藥機(jī)制,這種干預(yù)作用具有一定的量效關(guān)系。關(guān)鍵詞:補(bǔ)中益氣湯;肺腺癌;移植瘤;裸鼠;PDK;AKTDOI標(biāo)識(shí):doi:10.3969/i.issn.1008-0805.2014.09.018中圖分類號(hào):R734.2文獻(xiàn)標(biāo)識(shí)碼:A文章編號(hào):1008-080
