title: [Effects of Chaiqin Chengqi Decoction on activation of nuclear factor-kappaB in pancreas of rats with acute necrotizing pancreatitis].
abstract: OBJECTIVE
  To explore the mechanism of Chaiqin Chengqi Decoction (CQCQD) in treatment of rats with acute necrotizing pancreatitis (ANP).
  
  
  METHODS
  Thirty SD rats were randomly divided into 3 groups: sham-operated (SO) group, ANP group and CQCQD-treated group. ANP was induced by retro-pumping 3.5% sodium cholate to common bile duct. Blood sample was collected from abdominal vein for examination and the pancreatic tissue samples were taken for making pathology section 6 hours later. The pancreatic tissue (HE staining) was observed by light microscope. The content of tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) was detected with the method of enzyme-linked immunosorbent assay, and the activation of nuclear factor-kappaB (NF-kappaB) in pancreas was detected by immunohistochemical method.
  
  
  RESULTS
  Compared with the SO group, there was dramatic increase in the white blood cell (WBC) counts and AMY level in the ANP group (P<0.05, P<0.01). Compared with the ANP group, the WBC counts and AMY level in CQCQD-treated group were significantly reduced (P<0.05). The edema, inflammatory infiltration, haemorrhage and necrosis scores and total pathological score in the ANP group were obviously higher than those in the SO group (P<0.01). The edema, haemorrhage and inflammatory infiltration scores and the total pathological score in CQCQD-treated group were decreased (P<0.05). The integral optical density of NF-kappaB p65 positive cells of pancreas in CQCQD-treated group was lower than that in the ANP group (P<0.05).
  
  
  CONCLUSIONS
  CQCQD can reduce the content of serum TNF-alpha and IL-6, depress the activation of NF-kappaB, and lessen the pancreatic lesions.
