Objective To investigate the effects of edaravone on the levels of high sensitivity C-reactive protein(hs-CRP) and D-dimer in patients with acute ischemic cerebral infarction. Methods A total of 86 patients with acute ischemic cerebral infarction were randomly divided and assigned into therapy group and control group. The control group was given a routine treatment of acute ischemic stroke. The therapy group was treated with edaravone in addition to the routine treatment. hs-CRP and D-dimer were measured before and after treatment. Barthel index(BI) and Chinese stroke Scale(CSS) of two groups were assessed before treatment and after treatment. Results The levels of hs-CRP and D-dimer were deceased after treatment. After the start of edaravone ,the levels of hs-CRP and D-dimer of therapy group were significantly lower than those of control group(P ＜0.05). The scores of CSS and BI of two groups improved after treatment,and scores of CSS and BI of the therapy group were better than those of the control group(P＜ 0.05). Conclusion Edaravone could decrease the levels of hs-CRP and D-dimer and is beneficial to improve neurofunctional recovery.

Objective:To research the anti-inflammatory effect of LL-37 in mycobacterium tuberculosis ( Mtb ) infected-macrophages,as well as its influence on the secretion of inflammatory cytokines. Methods:( 1 ) THP-1 cells were cultured and incubated with phorbol 12-myristate 13-acetate (PMA) to transform into an adherent macrophage-like state (macrophage,Mφ). Then the THP-1 cell derived macrophages were infected with mycobacterium tuberculosis,and then stimulated with different concentrations of LL-37. (2)The experiment was divided into following groups: ① Control group:THP-1+normal saline (NS);② Mtb group:THP-1+Mtb;③Mtb+LL-37 5 μg/ml group:THP-1+Mtb+5 μg/ml LL-37;④Mtb+LL-37 10 μg/ml group:THP-1+Mtb+10 μg/ml LL-37;⑤Mtb+LL-37 20 μg/ml group:THP-1+Mtb+20 μg/ml LL-37. (3) The mRNA expression levels of IL-12p40,TNF-α,IL-4,and IL-10 will be determined by Real-time PCR respectively at 6,12,24 and 48 hours. The secreted levels of IL-12p40,TNF-α,IL-4,and IL-10 will be determined by ELISA analysis respectively at 6,12,24 and 48 hours. Results:The mRNA expression levels and secreted levels of IL-12p40,TNF-α,IL-4 and IL-10 were increased in Mtb group than those in control group. The mRNA expression levels and secreted levels of pro-inflammatory cytokines IL-12p40 and TNF-α were decreased in the LL-37 groups than those in Mtb group. However,anti-inflammatory cytokines IL-4 and IL-10 mRNA expression levels and secreted levels were increased in the LL-37 groups than those in Mtb group. Conclusion:Exogenous LL-37 inhibited the secretion of inflammatory cytokines in macrophages during mycobacterium tu-berculosis infection. The effect is related to the concentrations of LL-37 and the stimulated time of macrophages which were infected with mycobacterium tuberculosis. The results will provide new insights into the treatment of Mtb infection.

Young faculty are an essential part of a university's strength and is important for its sustainable development.And their scientific research capability is associated with the long-term development of the university.At present,there are 4 major problems with the development of young faculty's research capabilities,which include their relatively single academic knowledge structure,insufficient experience in writing proposals,insufficient opportunities for academic exchange,and inequity in resource allocation.Establishing a training mechanism may help solve some of the problems and promot their development.The research management department of a university must abandon erroneous traditional management concepts,provide research training seminars,develop a new mechanism to stimulate academic exchange,design a system for short-term laboratory rotations,and promote the participation of your faculty in major research projects.These may bring about marked improvement in the improvement of young faculty's research capabilities.

Mitochondria ATP synthase is a key enzyme in cellular energy interconversion. It is generally believed that ATP synthase is strictly confined to mitochondria. However, it has been demonstrated that ATP synthase also occurs on the extracellular surface of vascular endothelial cells, tumor cells and adipocytes, instead of normal cells. Based on this characteristic, many functional researches have been conducted on the angiogenesis, tumor inhibition and lipid metabolism, and the mechanism on which this enzyme works has been preliminarily elucidated. The research advances in cell-surface ATP synthase are reviewed in this paper.
