title: Clinical significance of dynamic detection for serum levels of MCP-1, TNF-α and IL-8 in patients with acute pancreatitis.
abstract: To observe dynamic changes of levels of monocyte chemotactic protein-1 (MCP-1), tumor necrosis factor-α (TNF-α) and interleukin-8 (IL-8) in patients with acute pancreatitis and to investigate its evaluation value on the severity of acute pancreatitis.
  
  
  
  A total of 109 patients with acute pancreatitis admitted were divided into mild acute pancreatitis group (MAP group, 42 cases), moderately severe acute pancreatitis (MSAP group, 35 cases) and severe acute pancreatitis (SAP group, 32 cases). ELISA was used to detect the serum levels of MCP-1, TNF-α and IL-8 of patients at day 1, day 4 and day 7 of admission to hospital.
  
  
  
  The serum levels of MCP-1, TNF-α and IL-8 from MAP group, MSAP group and SAP group at day 1 of admission to hospital all significantly increased. There was a significant difference between MAP group and control group, MSAP group and MAP group, SAP group and MSAP group (P < 0.05). The serum concentrations of IL-8 from MASP group and SAP group obviously increased at day 1, and there was significant difference between MASP group and MAP group, SAP group and MSAP group (P < 0.05), while the difference between MAP group and control group was not obvious (P > 0.05); The serum concentrations of MCP-1, TNF-α and IL-8 from MAP group all reached the highest level at day 4, which were significantly higher than the detection levels at day 1. In MSAP group and SAP group, the serum concentrations of MCP-1, TNF-α and IL-8 were the highest at day 1, which were significantly higher than the detection levels at day 4 and 7. At each detecting timing, the serum concentrations of MCP-1, TNF-α and IL-8 from MSAP group and SAP group were all higher than those of MAP group and MSAP group, respectively.
  
  
  
  The dynamic changes of serum levels of MCP-1, TNF-α and IL-8 in patients with acute pancreatitis have their rules, and the change rule of MAP group was different with that of MSAP and SAP group, which showed the reference value for the diagnosis and illness severity evaluation of acute pancreatitis.
