RESUMO

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.

RESUMO

<p><b>OBJECTIVE</b>To investigate the relationship between heart rate variability (HRV) and prostaglandin E2 (PGE2) in patients with renal insufficiencies.</p><p><b>METHODS</b>HRV blood and 24-hour urine prostaglandin E2 (PGE2) detection were detected in the following 4 groups of people: group A was a control group comprised of 20 normal individuals; group B had 20 patients with renal disease but exhibiting normal renal function; group C contained 20 patients with renal disease and compensatory renal function; group D had 20 patients demonstrating renal insufficiencies. The indices standard deviation of all NN intervals (SDNN), index of standard deviation of the averages of NN intervals (SDANN), mean of the standard deviation of all NN intervals performed on all 5-minute segments of the entire recording (SDNNindex), square root of the mean of the sum of the squares of differences between adjacent NN intervals (rMSSD) and NN50 count divided by the total number of all NN intervals (PNN50) were used to evaluate HRV, blood and 24-hour urine were determined by specific radioimmunoassay (RIA).</p><p><b>RESULTS</b>PGE2 in blood and urine and HRV exactly within 24 hours in patients with renal insufficiencies, negatively correlated with worsening damage to renal function. There was a slight or moderate correlation between blood and urine PGE2 and the SDNNindex, SDANNindex, SDNN, rMSSD and PNN50 indices (P < 0.05).</p><p><b>CONCLUSIONS</b>HRV and cardiac autonomic regulatory functions are decreased in the patients with renal insufficiencies, while lower levels of PGE2 may be a related factor.</p>
