Objective To investigate early changes of angiopoietin-2(Ang-2)in multiple trauma patients and assess its clinical significance.Methods Forty-five multiple trauma patients aged 2060 years admitted to the hospital within one hour after injury were randomly divided into three groups according to injury severity score(ISS).Blood specimens were obtained immediately upon arrival in the emergency department and plasma samples were assayed for comparing changes of Ang-2,TNF-a and IL-6.Meanwhile,plasma level of Ang-2 was measured and analyzed under different oxygenation index,shock index and base deficit.Results Plasma level of Ang-2 was positively correlated with ISS(P < 0.01)and was concordant with the plasma levels of TNF-a and IL-6(P<0.01).Furthermore,plasma level of Ang-2 was elevated upon increase of shock index or decrease of oxygenation index(P < 0.01).Plasma level of Ang-2 was elevated with the increase of base deficit(P < 0.01).Conclusions High level of Ang-2 is a marker of endothelial activation and dysfunction early after trauma.Ang-2 is related tightly with the injury severity,inflammation factors,systemic oxygenation and tissue hypoperfusion and may have a tight relation with pathophysiological development and clinical outcome after trauma.

A novel series of bis-nicotine derivatives (3a-3i) were designed, synthesized and evaluated as bivalent anti-Alzheimer's disease agents. The pharmacological results indicated that compounds 3e-3i inhibited both acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) in the micromolar range (IC50, 2.28-117.86 micromol x L(-1) for AChE and 1.67-125 micromol x L(-1) for BChE), which was at the same potency as rivastigmine. A Lineweaver-Burk plot and molecular modeling study showed that these derivatives targeted both the catalytic active site (CAS) and the peripheral anionic site (PAS) of AChE. Besides, these compounds could significantly inhibit the self-induced Abeta aggregation with inhibition activity (11.85%-62.14%) at the concentration of 20 micromol x L(-1).
