摘要
目的探讨黄芪多糖对老年晚期胃癌病人外周血中调节性T细胞(regulatory T cells,Tregs)表达及功能的影响。方法收集60例老年晚期胃癌病人,随机平均分为对照组(5%葡萄糖注射液)、低剂量组(黄芪多糖125 mg)及高剂量组(黄芪多糖250 mg),各组均于用药前后,应用流式细胞仪检测病人外周血中CD4+CD25+Tregs及CD4+CD25+Fox P3+Tregs的表达,应用ELISA法检测病人外周血中Treg相关抗炎细胞因子IL-10和转化生长因子-β1(TGF-β1)的含量,比较2组用药前后的差异。结果高剂量组外周血CD4+CD25+Tregs及CD4+CD25+Fox P3+Tregs的表达较用药前均明显降低(P<0.05),而低剂量组及对照组未见明显减少。同时高剂量组的IL-10及TGF-β1水平较用药前明显减少(P<0.05);而对照组的IL-10及TGF-β1水平较用药前未见明显减少,低剂量组TGF-β1水平较用药前降低(P<0.05)。结论黄芪多糖可能通过降低Tregs的表达及功能减轻老年晚期胃癌病人的免疫抑制状态。
