Value of spiral CT perfusion parameters for evaluating acute pancreatitis and their correlation with inflammatory factor and JAK2/STAT3 signaling pathway
Objective: To study the value of spiral CT perfusion parameters for evaluating acute pancreatitis and their correlation with inflammatory factor and JAK2/STAT3 signaling pathway. Methods: Patients with acute pancreatitis and patients with pancreatic trauma who underwent surgical resection in Liaocheng Dongchangfu People's Hospital between May 2014 and March 2017 were selected and enrolled in the AP group and the control group of the research respectively; spiral CT perfusion scanning was conducted before surgery to measure the blood flow (BF), blood volume (BV), and mean transit time (MTT), and the serum was collected to determine the contents of inflammatory factors; pancreatitis tissue and normal pancreatic tissue were collected after surgical resection to determine the expression of JAK2/STAT3 signal molecules. Results: pancreatic tissue BF and BV levels of AP group were significantly lower than those of control group while MTT level was not different from that of control group;CRP, PCT, HMGB-1, Ghrelin and sTREM-1 contents in serum as well as JAK2, STAT3, Bcl-2 and Bcl-xL mRNA expression in pancreatic tissue of AP group were significantly higher than those of control group and negatively correlated with BF and BV levels in pancreatic tissue. Conclusion: Spiral CT perfusion parameters BF and BV can reflect the microcirculatory disorder of acute pancreatitis and are associated with the increased secretion of inflammatory factors and the activation of JAK2/STAT3 signaling pathway in the course of disease.
