Abstract： 目的 探讨性别差异对脓毒症大鼠肝脏组织核因子-κB(NF-κB)活化的影响.方法 取40只清洁级Wistar大鼠,雌雄各半,采用腹腔注射内毒素(LPS)5 mg/kg制作脓毒症大鼠模型,利用凝胶阻滞迁移分析方法(EMSA)检测肝脏组织NF-κB的活化情况,同时检测大鼠血清中丙氨酸氨基转移酶(ALT),肿瘤坏死因子-α(TNF-α)以及雌二醇(E2)含量.结果 正常雌雄性大鼠肝脏组织有NF-κB的微弱活化,同时血清中TNF-α及ALT含量较少,各项指标在两组大鼠间差异无显著性(P＞0.05);脓毒症状态下各项指标明显升高,但是雌性大鼠各项指标的变化明显低于雄性(P＜0.01);相关分析表明,雌雄性脓毒症大鼠肝脏组织NF-κB的活化以及血清中TNF-α,ALT含量均与相应组别大鼠血清中E2含量呈显著负相关(P＜0.05).结论 脓毒症大鼠肝脏组织NF-κB的活化及血清中TNF-α,ALT含量存在性别差异,内源性雌激素可能介导了对雌性脓毒症大鼠肝脏的保护作用.
