摘要 目的探讨内毒素血症在新生儿全胃肠外营养相关性胆汁淤积(TPNAC)中的作用。方法新生新西兰白兔16只,随机分为2组,每组8只。A组为正常对照组,给母乳喂养;B组为全胃肠外营养组(TPN)组,持续给予全静脉营养。1周后处死动物,无菌条件下取门静脉血测定两组内毒素水平和肝功能指标,包括肝细胞损伤指标丙氨酸转氨酶(ALT)、天门冬氨酸氨基转移酶(AST);胆汁淤积指标碱性磷酸酶(ALP)、血清总胆汁酸(TBA)、总胆红素(TBil)、直接胆红素(DBil)和蛋白指标总蛋白、白蛋白、白球比。结果全静脉营养组内毒素水平明显高于正常对照组,分别为0.299±0.034和0.085±0.024,差异有统计学意义(t=14.54,P<0.01);且血浆内毒素水平分别与ALT、TBA、TBiL、DBil、总蛋白及白蛋白之间成线性关系,回归系数有统计学意义(t_b=7.126,4.441,8.574,12.562,10.153,12.975,P<0.01)。结论内毒素血症在新生儿TPNAC的发病中起重要作用,随着内毒素水平的升高,肝脏损害和胆汁淤积也随之加重。
