Objective To investigate the protective effect and its mechanism of edaravone against rat renal tubular epithelial cell injury induced by cisplatin. Methods The rat renal tubular epithelial cells (NRK-52E) were divided into the control, model control (50μmol·mL-1 cisplatin), group A (50μmol·mL-1 cisplatin plus 10μmol·mL-1 edaravone), B (50μmol·mL-1 cisplatin plus 20 μmol·mL-1 edaravone), and C (50 μmol·mL-1 cisplatin plus 40 μmol·mL-1 edaravone). The cell proliferation ability, content of malondialdehyde, activity of superoxide dismutase(SOD), level of reactive oxygen species ( ROS) , rate of apoptosis, express of protein and mRNA of Bax, Bcl-2 and Caspase-3 activation of cell were detected. Results The proliferation and SOD activity in NRK-52E cells declined, malondialdehyde and ROS were elevated upon being co-cultured with cisplatin. Moreover, the rate of apoptosis, express of protein and mRNA of Bax and Bcl-2, and Caspase-3 activation of cells were upregulated compared to the control group. However, edaravone stimulated cell proliferation, SOD activity and protein and mRNA of Bcl-2 and lowered content of malondialdehyde, level of ROS, rate of apoptosis, express of Bax protein and mRNA and Caspase-3 activation of cell(P<0. 05). Conclusion Edaravone can alleviate rat renal tubular epithelial cell injury induced by cisplatin, via inhibiting oxidative stress and down-regulating cell apoptosis.

Objective To evaluate the treatment effect of sustained low-efficiency diafiltration( SLEDF) on patients with severe acute pancreatitis( SAP). Methods Forty-two patients with SAP were randomly divided into continuous veno-venous hemofiltration( CVVH)group with 22 patients and SLEDF group with 20 patients. In addition to routine treatment,patients in CVVH and SLEDF were administrated to patients respectively in two groups. Mortality,incidence of complication,clinical symptoms,sign and laboratory examination and recovery time were recorded and measured. The scores of acute physiology and chronic health evaluation( APACHE)II and multiple organ dysfunction syndrome( MODS ) were performed. The level of C-reactive protein( CRP ),tumor necrosis factor-α( TNF-α),interleukin( IL )-6 and IL-8 were measured. Results There were no significant differences in terms of the mortality(90. 91% vs. 90. 00%;χ2 =0. 010,P=0. 920),incidence of complication (18. 18% vs. 20. 00%;χ2 =0. 023,P =0. 881)and recovery time of clinical symptoms,sign and laboratory examination in CVVH group and SLEDF( P﹥0. 05 ). There were also no significant differences between CVVH and SLEDF group in terms of scores of APACHE II((12. 1 ± 6. 1)vs.(11. 9 ± 7. 2);t=0. 097,P=0. 920), MODS((4. 3 ± 1. 7)vs.(4. 4 ± 1. 8);t=0. 185,P=0. 850),CRP((161. 7 ± 22. 9)mg/L vs.(157. 6 ± 21. 8) mg/L;t=0. 594,P=0. 550),TNF-α((5. 8 ± 1. 9)ng/L vs.(5. 7 ± 1. 8)ng/L;t=0. 175,P=0. 860),IL-6 ((4. 1 ±1. 2)pg/L vs.(4. 2 ± 1. 1)pg/L;t =0. 282,P =0. 780)and IL-8((3. 3 ± 1. 4)pg/L vs.(3. 2 ± 1. 0)pg/L;t=0. 268,P=0. 790)at 72 h post-treatment. However,the above test indices were decreased at 72 h post-treatment than those at admission(P﹥0. 05). Conclusion SLEDF and CVVH are proved with same treatment effect based on the levels of inflammatory cytokine,alleviating pathogenetic condition and improving prognosis in patients with severe acute pancreatitis.

Objective To study whether CK20 expression could be served as a noninvasive test for detecting and monitoring bladder cancer. Methods Reverse transcriptase polymerase chain reaction (RT PCR) was used to determine the expression of CK20 in cells collected from the urine of 10 healthy volunteers,41 patients with bladder cancer and in 20 hematuria patients with bladder cancer excluded. Results CK20 amplification band (370bp) was obtained with mRNA extracted from TCC cells of bladder cancer. Of 41 patients with bladder cancer, 37 specimen were positive.No false positive cases were found in the 10 healthy controls and only in 3 of the 20 hematuric cases.Of the 3 false positive, 2 had pelvic cancer and 1 chronic inflammation. CK20 was positive in 23 of the 25 G 1 patients,in 8 of the 9 G 2 patients,and in 6 of the 7 G 3 patients. Conclusions The preliminary results showed that CK20 might be a potential biomarker for the noninvasive detection of bladder cancer by means of assaying urothelial cells from the voided urine specimen with RT PCR.

Metabonom ics is an im portant branch of system biology follow ing the developm ent of ge-nom ics, transcriptom ics and proteom ics. It can perform high-throughput detection and data processing with multiple param eters, potentially enabling the identification and quantification of all sm all m etabolites in a biological system . It can be used to provide com prehensive inform ation on the toxicity effects, toxi-cological mechanisms and biom arkers, sensitively finding the unusual m etabolic changes caused by poi-son. This article mainly review s application of m etabonom ics in toxicological studies of abused drugs, pesticides, poisonous plants and poisonous anim als, and also illustrates the new direction of forensic toxi-cology research.

Objective To investigate the effect of atorvastatin on endothelial dilated function in the patients with coronary heart disease (CHD). Methods The dilatation of brachial arteries during reactive hyperemia and after sublingual administraction of glyceryl trinitrate (GTN) were measured by using B-mode ultrasonography in 120 patients. The endothelial dilatation changes 10～12 weeks after treatment of atorvastatin were observed. Results The content of TC, LDL-C and the incidences of hypertension and diabetes mellitus were higher in CHD group than those in the control group. The flow-mediated dilatation and GTN-induced dilatation of brachial arteries in patients with CHD were significantly reduced as composed with those in control group(P

Objectives To determine the serum levels of high mobility group box-1 protein ( HMGB1 )in patients with acute pancreatitis (AP) and to investigate the contributions of HMGB1 in the pathogenesis of AP. Methods The serum HMGB1 concentrations were determined by enzyme-linked immunosorbent assay in 33 patients with severe acute pancreatitis (SAP), 38 patients with mild acute pancreatitis (MAP) and 28 healthy controls at the time of admission within 72 h after the onset. THe relationships between the serum HMGB1 levels and sex, age, etiology, disease onset, Ranson score, Balthazar CT score, C-reactive protein,lactate dehydrogenase and serum creatinine, total bilirubin levels, local and systematic complications were analized. Results The serum HMGB1 levels in healthy control group, MAP group and SAP group were ( 1.82 ±0.64)μg/L, (6. 13 ±5.80) μg/L and (11.48 ±6.94)μg/L, respectively. The mean value of serum HMGB1 level in MAP group was significantly higher than that in healthy group ( P < 0. 05 ), while it was significantly lower than that in SAP group ( P <0.05 ). Within 24 h after disease onset, the serum levels of HMGB1 began to increase, and reached the peak at 48 h, then decreased and remained higher than normal value at 72 h.There were no remarkable relationships between the serum HMGB1 levels and sex, age, etiology, but it was positively correlated with Ranson score, Balthazar CT score, C-reactive protein, lactate dehydrogenase and serum crkatinine. The serum levels of HMGB 1 in patients with local and / or systematic complications were higher than those in patients without complications, but the difference was not statistically significant.Conclusions HMGB1 is a late inflammation mediator and serum HMGB1 levels were correlated with the severity of AP. HMGB1 may participate in the development of acute renal insufficiency during SAP.
