目的 探索促炎症及抗炎症细胞因子在脓毒症小鼠肝损伤中的作用。 方法 盲肠结扎穿孔(CLP)造成小鼠脓毒症模型,假手术(sham)组接受同样手术操作但不行CLP。用RT-PCR的方法检测了脓毒症小鼠肝组织中多种细胞因子(促炎症细胞因子TNFα、IL-1β、IL-6,抗炎症细胞因子IL-4) mRNA的表达,同时还测定了肝组织含水量及微血管通透性的改变。 结果 与sham组相比,CLP小鼠在3h后TNFα、IL-1β基因表达即明显增高(P<0.01),至12h仍然高于sham组(P<0.01),但较3h有所降低;IL-6基因在CLP后3h也明显增高(P<0.01),并且在CLP后12h仍继续增高(P<0.01);与之不同的是IL-4基因,在CLP后3h IL-4基因表达与sham组差异无显著意义,至CLP后12h才明显高于sham组(P<0.01)。CLP后3h肝组织含水量与肝微血管通透性即开始有所升高但与sham组比较差异无显著意义,至CLP后12h进一步增高与sham组比较差异均有显著意义(含水量P<0.05,微血管通透性P<0.01)。 结论 促炎症细胞因子与抗炎症细胞因子之间力量对比的失衡可能是脓毒症并发肝损伤的重要原因
目的 探索促炎癥及抗炎癥細胞因子在膿毒癥小鼠肝損傷中的作用。 方法 盲腸結扎穿孔(CLP)造成小鼠膿毒癥模型,假手術(sham)組接受同樣手術操作但不行CLP。用RT-PCR的方法檢測瞭膿毒癥小鼠肝組織中多種細胞因子(促炎癥細胞因子TNFα、IL-1β、IL-6,抗炎癥細胞因子IL-4) mRNA的錶達,同時還測定瞭肝組織含水量及微血管通透性的改變。 結果 與sham組相比,CLP小鼠在3h後TNFα、IL-1β基因錶達即明顯增高(P<0.01),至12h仍然高于sham組(P<0.01),但較3h有所降低;IL-6基因在CLP後3h也明顯增高(P<0.01),併且在CLP後12h仍繼續增高(P<0.01);與之不同的是IL-4基因,在CLP後3h IL-4基因錶達與sham組差異無顯著意義,至CLP後12h纔明顯高于sham組(P<0.01)。CLP後3h肝組織含水量與肝微血管通透性即開始有所升高但與sham組比較差異無顯著意義,至CLP後12h進一步增高與sham組比較差異均有顯著意義(含水量P<0.05,微血管通透性P<0.01)。 結論 促炎癥細胞因子與抗炎癥細胞因子之間力量對比的失衡可能是膿毒癥併髮肝損傷的重要原因

Objective To investigate the role of pro- and anti-inflammatory cytokines in sepsis induced liver injury in a mice model. Method Male NIH mice were subjected to cecal ligation and puncture (CLP) or sham operation (sham). Pro-inflammatory cytokine (TNFα, IL-1β, IL-6) and anti-inflammatory cytokine (IL-4) gene expression of the liver tissue were assessed by RT-PCR. The permeability of microvascular and water content in liver tissue were also examined. Result A significant increase in TNFα, IL-1β and IL-6 gene expression was observed at 3 and 12 hours after CLP. The level of TNFα and IL-1β at 3 hours was higher than at 12 hours, and the level of IL-6 gene expression at 12 hours was higher than at 3 hours. The level of IL-4 gene expression in the liver tissue was also increased at 12 hours after CLP. The microcirculatory permeability and water content in liver tissue significantly increased at 12 hours after CLP. Conclusion The unbalance of pro- and anti-inflammatory cytokine may play a key role in the development of sepsis induced liver injury.
