摘　　要：目的观察加味小柴胡汤对顺铂诱导的大鼠肝BRL细胞核转录因子-kB(NF-kB)、热休克蛋白70(HSP70)表达的影响。方法将BRL细胞分为4组:空白组、顺铂组及加味小柴胡汤大、小剂量组。采用完整细胞蛋白质斑点印迹、免疫组织化学等方法,检测各组细胞NF-kB、HSP70变化。结果顺铂组NF-kB表达明显较空白组升高,HSP70表达降低,组间比较差异有统计学意义;加味小柴胡汤大、小剂量组NF-kB明显较顺铂组低,差异有统计学意义;加味小柴胡汤大、小剂量组HSP70表达均升高,但仅加味小柴胡汤大剂量组差异明显。结论加味小柴胡汤可下调顺铂诱导的BRL细胞NF-kB表达,上调HSP70表达,此作用可能是该方减轻细胞氧化损伤、抑制细胞凋亡重要机理之一。Objective To study the effect of modified Xiaochaihu Decoction on NF-kB and HSP70 of BRL cell induced by cisplatin. Methods BRL Cells were divided into control group, cisplatin group, high and low dose of modified Xiaochaihu decoction. Complete cell protein dot blot technique and immunohistochemisth analysis were appllied to detect the change of NF-kB and HSP70. Results There was a significant increase in NF-kB and decrease in HSP70 of BRL cell induced by cisplatin compared with control group. There was a significant decrease of NF-kB in modified Xiaochaihu decoction group compared with cisplatin group. There were increases of the expression of HSP70 in both high and low dose group, but only the high dose group demonstrated significant difference. Conclution The expression of NF-kB of BRL cell induced by cisplatin can be inhibited while the expression of HSP70 can be enhenced by modified Xiaochaihu decoction. It may be one of important mechanisms of relieving cell oxidize lesion and inhibiting apoptosis by modified Xiaochaihu decoction.
