Objective: To give the living-donor and recipient medical evaluation and moral evaluation pretransplant by Academic and Ethics Committee for Organ Transplantation (AECOT), ensure the transplantation proceed smoothly and the feasibility for moral principles. Methods:AECOT was formed and gave the living-donor and recipient medical evaluation, additional moral evaluation to their family, evaluated the possibility for transplantation, ensured the long-dated safety for living-donor and recognition for ethics, ensured the transplantation proceed successfully. Results: 18 cases were evaluated by AECOT, two cases had the operation refused because of the II-diabetes for one living-donor and the other living-donor refused evaluation, one case had the operation delaied because of the overweight for the living-donor. The rest 15 cases were accepted operation smoothly,both donor and recipient recovered well post transplant. Conclusion:Academic and Ethics Committee for Organ Transplantation(AECOT) is a essential agency for Living Donor Kidney Transplantation.

OBJECTIVETo observe blood uric acid levels and Goldstein grading, as well as their correlation in Wilson's disease (WD) patients with different Chinese medical syndrome types.

METHODSTotally 906 WD patients in line with inclusive criteria were assigned to 6 groups, i.e., the heart spirit confused by phlegm group (HSCP, 26 cases), the phlegm-fire disturbing heart group (PFDH, 90 cases), the retention of damp-heat group (RDH, 113 cases), deficiency of qi and blood group (DQB, 168 cases), the deficiency of Gan-yin and Shen-yin group (DGYSY, 327 cases), the deficiency of Gan and Shen group (DGS, 182 cases) due to different Chinese medical syndrome types. Recruited were another 160 healthy subjects having similar ages and diet structures, who came for medical examinations, as the healthy control group. Venous blood was collected from the medial cubital vein of each-patient on an empty stomach in early mornings to detect blood uric acid levels. Results Blood uric acid levels were lower in each syndrome type group than in the healthy control group (146.08 +/- 67.24 micromol/L in the HSCP group; 157.08 +/- 69.77 micromol/L in the PFDH group; 162.58 +/- 97.72 micromol/L in the RDH group; 156.20 +/- 62.63 micromol/L in the DQB group; 161.83 +/- 111.23 micromol/L in the DGYSY group; 194.41 +/- 90.01 micromol/L in the DGS group; 242.39 +/- 87.55 micromol/L in the healthy control group, P < 0.01). Blood uric acid levels were higher in the DGYSY group than in the other 5 syndrome groups (P < 0.01). Correlation analyses between Goldstein grading and blood uric acid showed that, along with increased Goldstein grade (that was aggravating disease conditions), WD patients' blood uric acid levels decreased (P < 0.01).

CONCLUSIONSWD patient's blood uric acid levels decreased more. Blood uric acid levels and Goldstein grading were different in various Chinese medical syndrome types. Blood uric acid levels had certain value in assessing the severity of WD.

Objective To analyze C4d deposition in the patients with late acute renal allograft rejection,and explore the role of C4d in grafts survival and grafts loss. Methods Thirty-six patients clinical and pathologically diagnosed as having acute rejection more than one year post-transplant were selected. C4d was detected by immunohistochemistry in renal allograft biopsies. The effect of C4d deposition on long-term graft survival was studied. Results Among 36 recipients with late acute renal allograft rejection, 16 cases were positive for C4d (44.4 %) and 20 negative for C4d (55.6 %). Five cases experienced graft loss in C4d positive group (31.3 %), while 6 cases in C4d negative group (30.0%). There was no significant difference in the graft loss rate between C4d-positive group and C4d-negative group. Log-Rank test demonstrated there was no significant difference in graft survival between C4d-positive group and C4d-negative group. The count of the interstitial infiltrated eosinophils in renal allograft was (9.4 + 4.5) and (2.6 + 1.8) respectively in the C4d-positive group and C4dnegative group (P＜0.05). Conclusion C4d deposition in peritubular capillary of the recipients with late acute renal allograft rejection might not be a prognostic marker for graft outcome.

Objective To evaluate the localization of mitral valvular(MV)prolapse by transthoracic echocardiography(TTE),transesophageal echocardiography(TEE)and explore the interrelationship between the different subregions of MV prolapse and mitral regurgitation(MR).Methods Total of thirtythree patients with MV prolapse and more than moderate MR were included.TEE was used to further judge the location of scallop lesions and the result of both TTE and TEE were compared with the surgical findings respectively.The relationship between the different subregions of MV prolapse and MR was analyzed.Results Compared with the surgery findings,the accuracy rate of TTE and TEE in diagnosis of MV prolapse was 100％ qualitatively,80％ for TTE and 94％ for TEE in localizing the diseased region with the anterior and posterior MV,the result of TEE was significantly different from TTE(P＜0.05).MR level was related to the location of MV prolapse.Conclusions Compared with the TTE,TEE had more advantages in localizing the position of the MV prolapse.Mitral regurgitation is related to the location of MV prolapse.

OBJECTIVETo assess the accuracy of computed tomography angiography (CTA) in quantifying atherosclerotic area in the vascular wall of the carotid artery in comparison with high-resolution magnetic resonance imaging (MRI).

METHODSEighteen subjects (15 males and 3 females aged 63-/+8 years) with >or=50% stenosis in at least one carotid artery were enrolled in this study. CTA and high-resolution MRI scans (in-plane pixel size of 0.25 mmx0.25 mm for both) were conducted within 1 week on a multi-slice spiral CT scanner and a 1.5T MR scanner (Signa, GE Medical Systems), respectively. CTA images were matched with MR images with the carotid bifurcation as the mark. For each patient, multiple matched slices with carotid atherosclerotic plaques in the bilateral carotid arteries were selected to measure the outer wall boundary (OWB) area, lumen area and wall area. Bland-Altman analysis and Pearson correlation coefficients were used to analyze the correlations of the area measurements between CTA and high-resolution MRI.

RESULTSA wide range of lesion size (vascular wall area) was found in these patients. Strong correlations were noted between CTA and high-resolution MRI with the correlation coefficients for OWB area, lumen area and wall area of 0.98, 0.98 and 0.96, respectively. The mean differences between CTA and high-resolution MRI were 0.16-/+5.71 mm(2), 4.47-/+1.44 mm(2) and -4.31-/+5.73 mm(2) for OWB area, lumen area and wall area, respectively.

CONCLUSIONCompared to high-resolution MRI, CTA is also a reliable method to measure carotid vascular wall area. CTA might become an alternative modality to high-resolution MRI for follow-up examination of patients with carotid artery atherosclerosis, especially in uncooperative patients or patients with contra-indications for MRI.

OBJECTIVETo evaluate the capability of magnetic resonance imaging (MRI) using different sequences in displaying atherosclerotic carotid plaque composition.

METHODSThirty-five patients received pre- and post-contrast carotid MRI examination on a 3.0T scanner. TOF, T(1)W, T(2)W, PDW and CE-T(1)W were used for identifying the positive and negative cases for the plaque composition (lipid-rich necrotic core, intraplaque hemorrhage and calcification), and their respective sensitivity, specificity and Cohens κ with 95% CI for displaying the components of the plaques were calculated.

RESULTSA total of 74 plaques were found in the 35 patients, and after exclusion of 6 plaques for a thickness below 3 mm, 68 plaques were included for the analysis. Lipid-rich necrotic core were found in 57 plaques, intraplaque hemorrhage in 30 plaques, and alcification in 43 plaques. CE-T(1)W was the optimal sequence for displaying lipid-rich necrotic core with a sensitivity of 100%, specificity of 90.9%, and κ value of 0.944. Both T(1)W and TOF reliably showed the intraplaque hemorrhage, but the former had a greater sensitivity (100%), specificity (92.1%), and κ value (0.911). Of all the 5 sequences, TOF was the best to show calcification with high sensitivity (100%), specificity (92%), and κ value (0.936).

CONCLUSIONCE-T(1)W is the best sequence to show lipid-rich necrotic core with high sensitivity and specificity. T(1)W and TOF show a high level of agreement with the standard to show the intraplaque hemorrhage. TOF is more sensitive and accurate than the other sequences in displaying calcification. The combination of T(1)W, TOF and CE-T(1)W allows accurate evaluation of each component of the plaque.
