Abstract:
Objective To investigate the expression of TLR9 mRNA of peripheral blood mononuclear cells (PBMCs) in patients with acute pancreatitis .Methods Fifty two AP patients with the disease duration in 24 h were collected ,peripheral EDTAK2 coag‐ulation vein blood were collected on the first ,third and fifth day ,then plasma were cryop reserved to detect pancreatic elastase , proinflammatory cytokines and anti‐inflammatory cytokines .Then the peripheral EDTAK2 coagulation vein blood two to three months after treatment were collected in the same method to undertake these tests ,and act as the reference level value .Peripheral blood was collected from 36 acute pancreatitis patients .Three months later ,peripheral blood was collected again from these 36 peo‐ple as controls .PBMCs were isolated by Ficoll‐Hypaque gradient centrifugation .RT‐PCR was adopted to determine the relative con‐tent of the expression of TLR9 mRNA of the PBMCs .Results The relative content of expression of TLR9 mRNA were significant‐ly up‐regulated in the patients with acute pancreatitis ,compared with that of controls (P<0 .05) .The up‐regulated expression of TLR9 mRNA was related to expression of TNF‐a and IL‐1 .Conclusion The up‐regulated expression of TLR9 mRNA in acute pan‐creatitis patients indicates that infective factors might be mediated by TLR 9 .
