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.

Liposome-mediated nucleic acid delivery has been a focus recently, but in the course of delivering nucleic acid, some hurdles seriously limit the nucleic acid exerting treatment effect. This review refers to a series of problems such as low blood stability, reticuloendothelial system absorption, the lower targeting of liposome and the restriction of endosomal escape which are suffered in liposome-mediated nucleic acid delivery; and gives a detail introduction of strategies such as PEGylation, ligand modification, photochemical internalization, the application of degradation liposome and membrane-lytic peptide, to overcome those problems.

Objective To compare and analyse the esthetic effect of four kinds of the porcelain fused to metal crowns (PFMs) in restoring anterior teeth. Methods Based on single standard, a total of 371 anterior teeth from 110 patients were restored by PFM, in which 206 teeth of 59 patients were restored with Ni-Cr alloy PFM, 105 teeth of 29 patients with full circular procelain shoulder PFM, 35 teeth of 16 patients with titanium metal PFM, and 25 teeth of 6 patients with noble metal PFM. The esthetic effect was examined and analysed by single-blind method in one week and after one year. Results Between three days and one week, there was no difference among four PFMs in shapes and colors, which corresponded with adjacent teeth. The edge suitability was good and no significance was found in them. After one year, there was no difference of four PFMs in shapes and colors, which corresponded with adjacent teeth. The edge suitability of noble metal PFM was better than the other three, and the difference was statistically significant. Conclusion The esthetic effect is the best when noble metal PFM is used to restore anterior teeth and better with full circular procelain shoulder PFM.
