细胞因子在重症急性胰腺炎发病机制中的作用

重症急性胰腺炎是胰酶异常激活引起的全身炎症反应,受损的胰腺组织可作为抗原或炎性刺激物,使免疫系统和炎症反应中活化的细胞产生炎症介质、细胞因子、促发细胞冈子的级联反应,从而使局部病变发展为全身性的病损过程.促炎因子介导并加重组织损伤,而抗炎因子则平衡前者的损伤作用.抗炎促炎因子的相互作用,导致抗炎反应和促炎反应失衡,全身炎症反应综合征的出现,甚至发展成为多器官功能障碍综合征.

Funtion of cytokine in pathogenesy of severe acute pancreatitis

Severe acute pancreatitis is the systemic inflammatory reaction caused by the preternatural activation of trypsogen. The necrotizing pancrea as the antigen or stimulant, activiates immunocyte and in-flammatory cell to release a great deal of cytokines, including proinflammatery factor and anti-inflammatory factor. The former aggravates the damage of constitution, the latter could antigonize the damage of anti-inflam-matory factor. The unbalance of pro-and anti-inflammatory cytokines ,leads to the occurrence of systemic in-flammatory syndrome, even the mutiple organ failure.
