ABSTRACT
Objective To discuss the applied research of CT perfusion imaging on the diagnosis of splenic diseases. Methods 20 patients with splenic diseases which accepted treatment in our hospital from January 2012 to December 2014 were assigned into group A,including 7 cases of splenic lymphoma patients(group A1),8 cases of leukemia patients with spleen infiltration(group A2)and 5 cases of splenic metastasis(group A3). At the same time,20 healthy persons were selected as the control(group B). Results The result of CT scan was normal in group B,but that showed a variety of lesions in the spleen in group A. The spleen perfusion volume in the group A was significantly higher than that in the control group(P<0.05). The detection rate of CT perfusion imaging was significantly higher than that of CT scan(P<0.05). TIP and MTT in group A were significantly higher than those in group B,while BF,PEI and BV were significantly lower(P<0.05). Conclusion CT perfusion imaging has advantage of simple,short imaging time,less trauma,and a high diagnostic value for the spleen disease,which is an ideal detection means and can be used in clinic.
ABSTRACT
Objective:To study the effect of GABA and A receptor agonist THIP on proliferation and apoptosis of cytokine-induced killer (CIK) cells.Methods:CIK cells were cultured by routine method,and then treated with different concentrations of GABA and THIP.The proliferation of CIK cells were investigated by MTT assay.The apoptosis,cell cycle and immunophenotype were investigated by flow cytometry.Results:GABA could inhibit the proliferation of CIK cells in a dose-dependent manner and affect the distribution of cell cycle of CIK cells(P
