Objective The amount of neuroglobin(Ngb) in cerebral cortex after different post-traumatic time intervals were studied in order to find out the value of Ngb in estimating the survival time after trauma.Methods Moderate brain contusions in rats were made using free-falling-body impact device,The area and gray values of Ngb immunoreactive products(Ngb-IR)in the core of injury in cerebral cortex and penumbra and the contra lateral cerebral cortex at different time points after trauma were studied by immunohistochemical method and image analysis.Results The expression of Ngb in the core of injured cerebral cortex declined quickly and reached the nadir by 24 hours and remained at low level for long time.On the contrary,it rose quickly and reached the peak value at 12 hours in the penumbra surrounding the core of injury,then declined gradually and reached normal level at 8d to 16d.Image analysis revealed that the expression of Ngb-IR in the penumbra of injured cortex were stronger than that in the opposite side.Conclusion The amount of Ngb in cerebral cortex at the core and penumbra of injury changed regularly according to different time intervals after trauma.Ngb may play an important role in neuroprotection during acute phase of injury.

AIM　To elucidate the structure of the glycan of SPPA-1, a glycoconjugate isolated from Spirulina platensis. METHODS　Methylation analysis, GC/MS, and 1D, 2DNMR techniques were used to determine the structures of the glycoconjugate (SPPA-1). RESULTS　SPPA-1 was only composed of α-D-glucose and shown to be a (1→4) linked α-D-glucan to which a few glucosyl side chains are attached at O-6 of the glucosyl residues of the main chain. CONCLUSION　The glycan of SPPA-1 is a new glucan.

AIM:To investigate the effects of perfluorocarbon and ligustrazine on lung injury during liver transplantation in pigs with hepatopulmonary syndrome. METHODS:A hepatopulmonary syndrome (HPS) model of pig was established by chronic bile duct ligation. The animals were assigned randomly to 2 groups:(1) Perfluorocarbon in combination with ligustrazine treatment groups (PFCL group):the pigs were treated with intratracheal instillation of perfluorocarbon and ligustrazine; (2) The conventional mechanical ventilation group (MV group):all animals were subjected to mechanical ventilation and orthotopic liver transplantation. After 5 h the lungs were harvested for further analysis. RESULTS:The lung wet to dry weight radio,pulmonary permeation index and leukocyte count in bronchoalveolar lavage fluids (BALF) in PFCL group significantly decreased compared to MV group (P<0.05). Contents of tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) in the lung tissue,plasma and BALF of pigs in PFCL group were significantly lower than those in MV group (P<0.05). Moreover,the activation of NF-κB was inhibited markedly by PFCL. CONCLUSION:Perfluorocarbon in combination with ligustrazine effectively reduces the PMN accumulation in the lungs,inhibits TNF-α and IFN-γ production and protects against lung injury during liver transplantation in pigs with hepatopulmonary syndrome.

Objective To explore the relevance between lipoprotein(a) and atherosclerotic renal artery stenosis in adults.Methods Literature search was conducted in PubMed and EMBASE Database,using “atherosclerotic renal artery stenosis” as the search term as well as in Wanfang Database,China National Knowledge Infrastructure,and Cqvip Database,using “renal artery stenosis” and “lipoprotein” as the search terms,aiming to find case-control or cohort studies published before 2010.The qualities of all the literatures enrolled were evaluated using Newcastle-Ottawa scale and the data from which were analyzed by the Review Manager 5.0 software.Results Five eligible case-control studies (661 cases) entered the Meta analysis.The results showed that the lipoprotein(a) level was not significantly higher in the case group than that in the control group [ mean difference =0.0702 g/L,95％ CI ( - 0.0688,0.2092),P =0.32 ].Conclusion According to the existing studies,the relevance between lipoprotein(a) and atherosclerotic renal artery stenosis can not be established.

The purpose of this study is to explore depression metabolic markers in rat hippocampus and to investigate the anti-depressant effect of genipin and its mechanisms using nuclear magnetic resonance (NMR) metabonomics. Chronic unpredictable mild stress (CUMS) procedure was conducted to establish the depressive rat model. At the beginning of the third week, genipin low dose (25 mg x kg(-1)), middle dose (50 mg x kg(-1)), high dose (100 mg x kg(-1)), and venlafaxine (50 mg x kg(-1)) were given to the CUMS rats separately once daily for two weeks except control and model groups. Rat hippocampus was analyzed by 1H NMR based metabonomics after drug administration for 2 weeks. Significant differences in the metabolic profile of rat hippocampus of the CUMS treated group and the control group were observed with metabolic effects of CUMS including decreasing in glycine and N-acetylaspartate, increasing in inositol, glutamate, lactate, glutamine, taurine and alanine. Genipin showed ideal antidepressive effects at a dose of 50 mg x kg(-1) in rats, decrease of inositol, glutamate, lactate, alanine were observed, while glycine and N-acetylaspartate were increased. Important influence has been found on normal nervous system function of these significant changed metabolites, which suggests that the antidepressant effect of genipin may be played by enhancing the activity of neurons in hippocampus, repairing and improving the function of the neuron. The metabonomics approach is an effective tool for the investigation of the anti-depressant effect and pharmacologic mechanisms of genipin.

Fourty wistar rats were used for experimental study of myocardial infarction (MI )induced by ligation of the left coronary artery. The results showed that the AF and HBFP stalng as well as Ao fluorescence were sensitive in demonstrating the early MI changes occuced 1 ~ 2 hour after coronary arteryligation. The TTC stamg method was reliable for demonstrating the MI margin. Both HBFP and AOfluorescence were under no influeence of the post-mortem autolysis, but the AF reaction were undeithe influence of the early post-mortem autolysis. Four hours were required for complete developemenof MI. The early stage of MI demonstrated by SEM was conslstant with that bv TEM. Both resuhwere influenced by the post-mortem autolysis.

OBJECTIVE:To investigate the protective effect of the compatibilities of ginsenosides Rg1 and aconitine on myocar-dial cell of in vitro cultured heart failure model. METHODS:The myocardial cells of neonate rat were grouped into normal control group,model group,positive control group(Deslanoside injection,1×10-7 mol/L),ginsenosides Rg1 group(1×10-8 mol/L),acon-itine group (1 × 10-9 mol/L) or their compatibilities groups (1∶1,2∶1,1∶2,V/V). Except for normal control group,other groups were given 0.8%pentobarbital sodium to induce heart failure model of myocardial cells. After modeling,each group was given rele-vant medicine for 1 h,and then the activities of T-ATPase,Ca2+-Mg2+-ATPase,Na+-K+-ATPase in cells were all detected. The activi-ties of acyl carrier protein(ACP)and lactate dehydrogenase(LDH),and the contents of brain natriuretic party(BNP),TNF-α and total glycogen were measured in cell culture fluid. RESULTS:Compared with normal control group, T-ATPase and Ca2+-Mg2+-ATPase activities were decreased significantly in model group;meanwhile,Na+-K+-ATPase activity was increased signifi-cantly,and ACP,LDH activities and BNP content in cell culture fluid were increased significantly(P<0.05). Compared with mod-el group,the activities of T-ATPase in treatment groups were increased significantly,while the activity of LDH in cell culture fluid was decreased significantly;when the volume ratio of ginsenoside Rg1 to aconitine was 2∶1,protective effect was the strongest;the activities of Na+-K+-ATPase in aconitine group and compatibility groups were all decreased significantly,with statistical signifi-cance(P<0.05). The activities of ACP and BNP in cell culture fluid were all decreased in treatment groups,but the content of to-tal glycogen in cells and the TNF-α content of in cell culture fluid had no change (P>0.05). CONCLUSIONS:Compatibility of ginsenosides Rg1 and aconitine can improve ATPase activities and membranous permeability,regulate BNP secretion and protect myocardial cell of heart failure model,especially the compatibility of ginsenosides Rg1 to aconitine of 2∶1 ratio.
