目的  研究腹腔應(yīng)用氟尿嘧啶（FU）對腫瘤動物模型CO2氣腹操作后腫瘤細胞的生長與轉(zhuǎn)移的作用。
方法  選取雄性清潔級H-22 小鼠50只，全部接種S-180細胞懸液，平均分成5組： 單純種植組、氣腹組、氣腹+生理鹽水組、氣腹+低濃度（5.0 g/L）FU組和氣腹+高濃度（10.0 g/L）FU組。11 d后全部處死，觀察腫瘤腹壁種植情況和瘤重（腹水重量差值），并通過免疫組化方法檢測增殖細胞核抗原（PCNA）和血管內(nèi)皮生長因子（VEGF）的表達水平。
結(jié)果  除氣腹+低濃度FU組外，其余3組的瘤重均明顯高于氣腹+高濃度FU組，差異有統(tǒng)計學意義（P＜0.05或P＜0.01）。氣腹+高濃度FU組抑瘤率為64.5%，氣腹+低濃度FU組抑瘤率為43.3%。氣腹+生理鹽水組穿刺孔種植瘤結(jié)節(jié)直徑明顯大于氣腹+高濃度FU組和氣腹+低濃度FU組，差異有統(tǒng)計學意義（P＜0.01）。各組小鼠腹水中腫瘤細胞和種植瘤結(jié)節(jié)中PCNA和VEGF表達的差異均有統(tǒng)計學意義（P＜0.05，P＜0.01）。
結(jié)論  腹腔內(nèi)應(yīng)用高濃度的FU對于S180細胞氣腹動物模型的瘤重、穿刺孔種植瘤結(jié)節(jié)有抑制作用，其機理可能與下調(diào)PCNA和VEGF的表達有關(guān)。
