  1. * P value is the statistical value of ANOVA
  2. a Significant difference compared with the sterile group; b significant difference compared with the pancreatic infection group; c significant difference compared with the extrapancreatic infection group; d significant difference compared with the combined infection group, P <0.05 represents a statistically significant difference
