Objective To evaluate the multi-detector CT (MDCT) on pulmonary changes in post-operative adult receptor of liver transplantation complicated with acute respiratory distress syndrome (ARDS).Methods Nineteen adult patients admitted into Tianjin First Center Hospital from January to December 2016 to perform the first time liver transplantation were enrolled in this study. Before operation, the CT showed no significant abnormality in the patients' lungs, after operation MDCT was applied to observe the pulmonary changes of ARDS post-operative complication in the adult receiver of liver transplantation, and the pulmonary changes in different gender of patients were analyzed and compared.Results MDCT showed that after liver transplantation all the 19 patients (100%) had lung pathological changes, of whom 18 cases (94.7%) manifested 2 or more than 2 kinds of pulmonary changes, including consolidation shadows (12 cases, 63.2%), patchy shadows (2 cases, 10.5%), ground glass opacity (6 cases, 31.5%) and pleural effusion (18 cases, 94.7%). In the comparisons between male and female patients with post-operative ARDS after liver transplantation, there were no significant differences in the lung pathological changes shown in MDCT (allP > 0.05) statistically.Conclusion The application of MDCT has great potential value in the evaluation of the disease situation after liver transplantation, that might providehelp to the postoperative treatment.

Objective To correlate between the IQQA(R)-Liver system in planning liver resection and the actual operation performed by surgeons.Methods The data on 65 patients were retrospectively studied.Their preoperative enhanced CT images were analyzed by the IQQA(R)-Liver system to determine the operative plan (Group Q) including the operative technique,the major vessels which required to be transected and the virtual liver resection volume.The above results and the corresponding data collected from the actual operation (Group S) were statistically analyzed to find out whether there was any correlation between them,thus determining the clinical significance of the IQQA(R)-Liver system in preoperative evaluation.Results Group Q and Group S had good correlation in the operative techniques (O) and in the major vessels that required to be transected (A) (uO =0.835,uA =0.893) with no statistical difference between the 2 groups (PO =0.494,PA =0.331).The virtual liver resection volume was 633.96 ± 512.06 (78.30 ~2 559.38)cm3.Conclusion Preoperative evaluation by the IQQA(R)-Liver system had significance in planning partial hepatectomy.

Objective To compare the health related quality of life (HRQoL) of ileal conduit versus orthotopic ileal neobladder using the FACT-BL scale.Methods One hundred and thirty patients underwent radical cystectomy and urinary diversion for invasive bladder cancer from Jan 2006 to Dec 2010 at our hospital.According to different urinary diversions,patients were divided into ileal conduit (IC) and orthotopic ileal neobladder (NB).HRQoL was assessed using FACT-BL.The following scores calculated from the FACT-BL questionnaire and list:physical well-being ( PWB ),social/family well-being ( SWB ),emotional well-being(EWB),functional well-being( FWB),overall bladder-special subscale and total FACT-BL were included.A high FACT score indicated a high level of HRQoL.The medical records of each patient were then reviewed.Clinical parameters including age,sex,type of diversion and pathological status were recorded and analyzed.Results A total of 94 questionnaires were collected,of these patients 50 had an IC and 44 had an NB.Among the respondents,the age at surgery was significantly younger in NB group than IC group (P =0.014 ).While the percent of males,follow-up years and pathological stage T3 or greater revealed no significant difference.The NB group got significantly higher scores in PWB,SWB,EWB and FACT-BL than the IC group.Which indicated that the HRQoL was higher in patients following orthotopic ileal neobladder.Conclusions The HRQoL was better in patients who followed orthotopic ileal neobladder than those who followed ileal conduit.This may indicate that orthotopic ileal neobladder should be considered first when making a decision about which urinary diversion should be used.

Purpose To investigate the value of MRI T2 mapping imaging in diagnosis of lumbar intervertebral disc degenerative (IVDD).Materials and Methods A prospective study was performed on 100 patients who underwent 1.5T MRI examination because of lumbar and back pain from October 2013 to December 2015 at the Fifth People's Hospital of Shanghai,Fudan University.The MRI examinations included conventional sagittal T1WI and T2WI,axial T2WI and median sagittal T2 mapping imaging.According to Pfirrmann standard,475 lumbar intervertebral discs were graded.T2 values of nucleus pulposus (NP) and annulus fibrosus (AF) of anteriority and posterior with different grades were measured and compared.The correlations between T2 value,age and grade were further analyzed.30 patients were selected and underwent a second MR examination after half a year,and the difference of T2 values between the two MR examinations were compared.Results Except for grade Ⅳ and grade Ⅴ,the differences of T2 values of NP between the other grades of lumbar intervertebral discs were statistically significant (P<0.05).T2 values of NP were negatively correlated with the grades (r=-0.77).There were no significant differences in T2 values of NP and AF of anteriority and posterior in 30 patients with back pain between the two MR measurements of half year interval (P>0.05).Conclusion T2 mapping imaging can quantitatively assess the degree of IVDD,especially T2 values of NP can reflect the differences of IVDD with grade Ⅰ-Ⅳ,so it can provide the imaging evidence for the diagnosis of IVDD.
10.The research progress of cardiac magnetic resonance in diagnosis of myocardial amyloidosis
Chinese Journal of Integrated Traditional and Western Medicine in Intensive and Critical Care 2019;26(3):383-385
Cardiac involvement in amyloidosis has a relatively poor prognosis, and early diagnosis and treatment is very important to the prognosis of such involved patients. "One stop type" cardiac examination can be carried out by the cardiac magnetic resonance imaging (CMRI) and the evaluation of cardiac morphology and function can be complete. "One stop type" CMRI may show the thickness of myocardium in left ventricle, cardiac diastolic dysfunction, sub-endocardial enhancement (patch, diffuse and transmural types), rising of T1 value, too fast clarifying rate of contrast agent in blood pool, pericardial and/or pleural cavity effusion, that may help to elevate the efficiency of diagnosis. The CMRI presents myocardial tissue characteristics quite well, that may help for early diagnosis of myocardial amyloidosis, and clearly demonstrate the situation of heart involvement; to follow-up patients with repeat CMRI examinations can monitor drug therapeutic effect, direct and regulate treatment, judge prognosis, etc. so that CMRI possesses very high clinical application value.
