With the time of therapy extended,NSE levels declined progressively. There were no significant adverse drug reactions during the treatment period. Conclusions The influence of edaravone therapy on serum levels of NSE in the patients of severe brain trauma is significant,edaravone for patients with severe brain trauma has a better curative effect ,medication safety,and fewer adverse drug reactions during acute phase.

Objective To purify Micrococcus luteus Rpf and Rpf domain fusion protein, and to in-vestigate its effects on growth of Mycobacterium tuberculosis. Methods The recombinant plasmids pPro-EXHT-Rpf and pPro-EXHT-Rpf domain were expressed in E. Coli DHSa and then purified under denaturing condition via Ni-NTA purification system and confirmed by Western blot. The biochemical property of the M. Luteus Rpf and Rpf domain was analyzed by stimulating the resuscitation of M. Tuberculosis H37Ra which were in non-culturable' condition. Results The Rpf and Rpf domain products achieved 95% and 93% pure respectively, and the molecular weight was 30 x 103 and 12 x 103, the yield of purification was about 471 mg/L and 337 mg/L of the culture. The M. Luteus Rpf and Rpf domain from the E. Coli showed activity of stimulating the resuscitation of M. Luteus and M. Tuberculosis H37Ra in non-cuhurable' condition which could be inhibited by monoclonal antibodies of M. Luteus Rpf domain remarkably. Conclusion It was dem-onstrated that the purification of Rpf and Rpf domain have high biological activity for further functional, pharmacological and clinical investigations, and M. Luteus Rpf domain protein is fully active as M. Lateus full-length Rpf.

To investigate the effect of glycyrrhizinate and phospholipids (DGPL) complex on inflammatory gene expression in cell inflammation model induced by palmitic acid (PA).Huh7 cells were divided into control, PA and PA+DGPL groups. For control group, cells were treated with BSA; for PA group, cells were incubated with 0.2 mmol/L saturated fatty acid PA, PA+DGPL group was given 20 μmol/L or 100 μmol/L DGPL in addition to 0.2 μmol/L PA. After 24 h, the expression of inflammation-related genes COX-2 and iNOS and endoplasmic reticulum (ER) stress-related gene GRP78 was determined by RT PCR. Oil red staining was conducted to observe the effect of DGLP on steatosis.Compared with control group, the expression of COX-2, iNOS and GRP78 in PA group was enhanced to 6.07±0.73(<0.05), 3.18±0.91 (<0.01) and 3.21±1.00(<0.05), respectively. Compared to control group, the expression of COX-2,iNOS and GRP78 in 100 μmol/L DGPL group was reduced to 2.40±0.76, 1.60±0.49 and 1.17 ±0.42 (<0.05); and 20 μmol DGPL had similar inhibition effect on COX-2 and iNOS elevation induced by PA (<0.01,<0.05 respectively). In addition, DGLP enhances the steatosis of Huh7 cells as demonstrated by oil red staining.PA can induce the up-regulated expression of inflammation associated genes COX-2, iNOS and ER stress-associated gene GRP78 in Huh7 cells. DGPL is able to protect Huh7 cells from PA induced inflammatory gene expression and the beneficial effect may be partially due to its unsaturated phospholipid component, which may improve ER stress and enhance steatosis.

Objective: To investigate the role of neutrophil elastase inhibitor, sivelestat, in preventing and treating nonalcoholic steatohepatitis (NASH) and its underling mechanisms. Methods: A total of forty 4-week-old male C57BL/6J ApoE-/-mice were equally divided into the following four groups: standard chow (SC)+isotonic saline; SC+sivelestat; high-fat, high-cholesterol (HFHC) diet+isotonic saline; and HFHC+sivelestat. These mice were treated with above methods for 12 weeks. Blood and liver tissue samples were collected to measure biochemical parameters, hepatic steatosis and non-alcoholic fatty liver disease (NAFLD) activity score (inflammation) were evaluated by oil red O staining and HE staining, respectively. The mRNA and protein expression levels of hepatic inflammatory cytokines, CD68, and F4/80 were determined by quantitative RT-PCR and immunohistochemistry, respectively. Comparison of means between the four groups was made by one-way analysis of variance, and comparison between any two groups was made by the LSD or SNK method (for data with homogeneity of variance) or the Tamhane or Dunnett method (for data with heterogeneity of variance). Results: Mice fed with an HFHC diet for 12 weeks developed typical pathological features of NASH compared with those fed with SC. Compared with mice fed with HFHC diet without sivelestat, those treated with HFHC and sivelestat exhibited the following features: (1) significantly reduced fast blood glucose, blood cholesterol, and hepatic biochemical parameters, as well as increased insulin sensitivity; (2) significantly reduced NAFLD activity score (5.71±1.11 vs 3.16±1.16, P < 0.05); (3) reduced monocyte chemoattractant protein-1 and tumor necrosis factor -α; (4) significantly reduced mRNA levels of CD68 and F4/80; and (5) reduced expression of CD68 in the liver. Conclusion Sivelestat alleviates the hepatic steatosis and inflammation of NASH in mice by inhibiting the activation of Kupffer cells.
