RESUMEN
Objective To explore the diagnosis value of dual energy CT in severity analysis of acute pancreatitis.Methods Pancreas CT perfusion images of 60 patients were formatted using the method of Siemens dual energy CT.According to the severity of the acute pancreatitis,60 patients were divided into 3 groups:normal control (NC)group,mild acute pancreatitis (MAP)group and severe acute pancreatitis (SAP)group.Every group had 20 patients.Blood flow(BF),blood volume(BV),permeability of capillary surface (PS)and mean transit time(MTT)were calculated by Siemens MMWP workstation post process software.The meaning of these CT perfusion parameters for severity of acute pancreatitis was analyzed.Results Compared to the NC group,BF and BV in MAP,SAP group were reduced significantly (P 0.05).We also found in ≥45 years old patients,MTT in both MAP and SAP groups were higher than NC group(P <0.05).Conclusion (1)BF and BV are useful in diagnosis of acute pancreatitis and analysis of severity of it.(2)PS is useful in diagnosis of acute pancreatitis.(3)MTT is useful in diagnosis of acute pancreatitis in elderly patients (≥45 years old).
RESUMEN
Human cytomegalovirus (HCMV) has a higher prevalence in the population, and most normal individuals after primary infection can establish latent infections. Recent reports have suggested that cytomegalovirus infection associated with lipid metabolism, and play an important role in the pathogenesis of many diseases, such as hepatitis, atherosclerosis, isolated syndrome, metabolic syndrome, etc. This article summarized the relationship between cytomegalovirus infection and lipid metabolism, as well as its role in a variety of diseases progression.
