Objective To study the influences of fenofibrate on oxidative stress and endoplasmic reticulum stress in livers of hyperlipidemic rats. Methods Male SD rats were fed with high-fat diet for 12 weeks to induce a model of hyperlipidemia, then divided into control group, high-fat diet group with another four-week high-fat diet and fenofibrate group, in which rats were treated with fenofibrate [100 mg / (kg·d)] for 4 weeks. Then improvement of insulin resistance was detected in rats with GTT and ITT experiment. The serum levels of glucose (GLU), fasting insulin (FINS),triglyceride (TG) and total cholesterol (TC) were detected. The pathological changes of livers were detected with Oil Red O staining. The oxidative stress indices such as T-SOD, Mn-SOD, GSH and T-AOC were detected with liver homogenate. The expression of GRP78 was detected with real-time quantification RT-PCR and Western blot analysis respectively. Results Compared with rats with high-fat-diet, rats after fenofibrate treatment showed obviously improved insulin resistance, lower serum level of TG, TC and FINS (P < 0.05), decreased number and size of lipid droplets in liver tissue sections. T-SOD level in liver homogenate was significantly increased (P < 0.05), while GSH and T-AOC levels increased but had no obvious differences when compared with control group (P > 0.05). The expression of GRP78 at mRNA and protein levels were increased significantly after fenofibrate treatment (P < 0.05). Conclusions Fenofibrate has significant effects on improving insulin resistance and lipid regulation, which might be related to decreased oxidative stress and subsequent endoplasmic reticulum stress.

ObjectiveTo evaluate the diagnostic value of multi-slice CT (MSCT) and multi-dimensional reconstructions for congenital pulmonary stenosis (PS) in children.MethodsThe enhanced thin CT images of 33 patients with PS were retrospectively analyzed,the data was transmitted to the workstation for multi-planar reformation ( MPR),volume rendering technique (VRT) and maximum intensity projection (MIP).The CT imaging features of PS were analyzed combining with operation resul ts and Ultrasonic Cardiogram (UCG).ResultsIn 33 cases of PS,there were 17 cases with pulmonary valve stenosis (PVS),10 cases with right ventricular infundibulum stenosis (RVIS),and 6 cases with pulmonary trunk stenosis (PTS).The first two were correctly diagnosed by UCG,5 cases of PVS and Icases of RVIS were correctly diagnosed by MSCTA,the later was correctly diagnosed by UCG and MSCTA.In 14 cases with collateral circulations between aorta and pulmonary artery ( APC ),all were correctly diagnosed by MSCTA,only 3 case was diagnosed by UCG,1 case was misdiagnosed as PDA.UCG can clearly demonstrate the others intra-cardiac deformities,such as ASD,VSD,RVH,PFO,SV,DORV,TECD and TBD,the accuracy rate of MSCTA was 39.4％,and MSCTA can clearly demonstrate the origin,course and diameter of extracardiac vascular abnormalities,such as PDA,RAA,TGA,TAPVD,CoA,PLSV and VLSA,the accuracy rate of UCG was 697％.ConclusionsMSCT and multi-dimensional reconstruction were a kind of non-invasive method,it was a good approach for extra-cardiac vascular malformations and APC in PS.Combining with UCG,it can further be used to improve the diagnostic accuracy of intra-cardiac malformation and supply diagnostic evidence for clinical treatment.

ABSTRACT:Objective To detect the expressions of thioredoxin (TRX1)and c-jun-activation-domain binding protein-1 (JAB1)in patients with acute myelogenous leukemia (AML)and healthy controls,and measure the TRX1 level in AML patients at different stages for evaluating its clinical significance.Methods The expressions of TRX1 and JAB1 in leukemia samples were analyzed by RT-PCR and Western blot at mRNA and protein levels, respectively.The correlation between TRX1 and JAB1,and the relationship between the gene expression and peripheral blood leukocytes count were also analyzed.Furthermore,serum TRX1 was measured by ELISA.Results TRX1 and JAB1 expressions at both mRNA and protein levels were obviously upregulated in leukemia patients (P<0.05). TRX1 was positively related to JAB1 in both newly diagnosed and recurrent AML patients.And high levels of TRX1 and JAB1 expressions were associated with white blood cell (WBC)counts in AML patients (P<0.05).Moreover, abundance of TRX1 in serum was significantly greater in AML patients,especially in the patients with recurrent AML,than in healthy donors (P<0.05).Conclusion There is a positive correlation between the expressions of TRX1 and JAB1 ,which is closely related to the occurrence and progression of AML.

Objective To study the mechanism of oxidative stress involved in the pathogenesis and relapse of acute monocytic leukemia (M5 ).Methods We detected reactive oxide species (ROS)levels,conducted plasma analysis obtained from 76 M5 patients at diagnosis and at relapse,and observed the ultrastructure of mitochondria of mononuclear cells in peripheral blood by transmission electron microscope.Results Compared with that in the control group,the average fluorescence intensity of intracellular ROS was significantly increased in M5 groups, especially in the relapse patients (P < 0.05 ).Low total antioxidative capacity (T-AOC)and antioxidant enzyme activity were characteristic of M5 at both diagnosis and relapse. However, lactate dehydrogenase (LDH ), malondialdehyde (MDA)and 8-hydroxy-2’-deoxyguanine (8-OHdG)increased significantly at both diagnosis and relapse (P < 0.05 ).Prominent ultrastructural abnormalities (mitochondrial swelling,outer membrane blebs,and aberrant cristae disorder)were present in patients with primary M5,and they were obviously abnormal in relapsing M5 patients.Conclusion Oxidative stress is the initiating factor of M5.Mitochondria are the main intracellular location for ROS generation.To maintain the dynamic balance between ROS and antioxidant defence may be the critical factor for preventing relapse.

Objective To assess the value of multi-slice spiral CT in the diagnosis of hepatic venous outflow obstruction (HVO) after liver transplantation. Methods Five patients with HVO were confirmed with digital subtraction angiography and epigastric tri-phase contrast-enhanced CT scans within 4-102 days after liver transplantation, and the CT dynamic enhancement features were retrospectively evaluated. Results Among 5 patients, 2 had middle hepatic vein obstruction, 1 had left hepatic vein obstruction, 1 had right hepatic vein obstruction, and 1 had middle hepatic vein and inferior caval vein obstruction. Contrast-enhanced CT showed typical liver congestion in all 5 patients. The liver parenchyma drained by obstructed hepatic vein was low-density on CT plain scans (1 patient showed mix-density caused by liver parenchyma hemorrhage), while no enhancement on artery phase, moderate enhancement on venous phase and high enhancement on delay phase were observed. During the venous phase, peripheral portal branches were invariably enhanced in the congested area of liver parenchyma. During the delay phase, opacification of the obstructed hepatic vein could be seen. After all patients had treated with interventional therapy, their clinical symptoms were improved, and 2 patients received contrast-enhanced CT scans after interventional therapy, which showed liver congestion relieved and obstructed hepatic vein opacificated well in venous phase. Conclusion Multi-slice spiral dynamic enhancement CT scans can accurately display the location of HVO and the extent of liver congestion.

Objective To evaluate the relationship between CD4+ T lymphocyte count and results of enzyme-linked immunospot (ELISPOT) assay in human immunodeficiency virus (HIV)-Mycobacterium tuberculosis (M.tb) coinfected patients.Methods A total of 193 HIV-infected individuals in Yunnan Province and Shanghai were enrolled.T-SPOT.TB assay was employed to detect M.tb specific T lymphocyte in the peripheral blood mononuclear cells (PBMC).CD4+ T lymphocyte in PBMC from the enrolled subjects was detected by flow cytometry.Data were analyzed using t test.ResultsThe incidence of latent tuberculosis in HIV-infected individuals was 30.6％.The CD4+ T lymphocyte counts in HIV-infected individuals with active tuberculosis were 190×106/L,which were significantly lower than those in HIV-infected individuals with latent tuberculosis (484×106/L; t=6.665,P＜0.01).The HIV-infected individuals were stratified according to CD4+ T lymphocyte counts of ＞500×106/L,200×106-500×106/L,and ＜200×106/L and the constituent ratios of active tuberculosis/latent tuberculosis were 1∶16.2,1∶1.3 and 5.6∶1,respectively.Among 79 subjects with positive T-SPOT.TB results,20 were coinfected with active tuberculosis,in which 14 had CD4+ T lymphocyte counts of ＜200 ×106/L,5 had 200×105-500×106/L and 1 had ＞500×106/L.Fifty-two in 59 HIV/latent tuberculosis patients individuals had CD4+ T lymphocyte counts of ＞200×106/L.ConclusionsThe prevalence of latent tuberculosis in HIV-infected individuals is high in China.Cellular immunity in HIV-infected individuals with active tuberculosis is severely impaired.With the decrease of CD4 ′ T lymphocyte counts,patients with latent tuberculosis are prone to develop active tuberculosis in HIV-infected individuals.The negative predictive value of T-SPOT.TB is significantly diminished in patient with low CD4+ T lymphocyte counts,especially less than 200×106/L.
