Objective To investigate the effects of propofol on death-associated protein kinase (DAPK) mRNA expression in a rat model of traumatic brain injury (TBI). MethodsSixty male Wistar rats with a mean age of 3-4 months and mean body weight of 250-300 g were randomly divided into 6 groups ( n = 10 each) : Ⅰ normal control;Ⅱ sham operation; Ⅲ TBI; Ⅳ normal saline (NS) +TBI;Ⅴ fat emulsinn+ TBI and Ⅵ propefol + TBI. TBI was produced according to Feeney et al. In group Ⅲ-Ⅵ the animals were killed and their brains were removed at 24 h after brain contusion. NS 2 ml·kg-1 · h-1 , 10% fat emulsion 2 ml · kg-1 · h-1 and propofol 2 ml·kg-1·h-1 were infused iv for 4 h after lead trauma in group Ⅳ, Ⅴ and Ⅵ respectively. DAPK mRNA expression in the brain tissue was determined by RT-PCR and neuronal apeptosis was assessed by TUNEL. Results The expression of DAPK mRNA and neuronal apoptosis were significantly increased in the TBI group as compared with normal control and sham operation groups. Propefol infusion significantly attenuated neuronal apoptosis and reduced DAPK mRNA expression as compared with TBI, NS and FE groups. ConclusionPropofol can protect the brain from traumatic injury by suppression of the expression of DAPK mRNA.

A sesquiterpene synthase (AsSS4) full-length open reading frame (ORF) cDNA was cloned from wounded stems of Aquilaria sinensis by RT-PCR method. The result showed that the ORF of AsSS4 was 1,698 bp encoding 565 amino acids. Prokaryotic expression vector pET28a-AsSS4 was constructed and transformed into E. coli BL21 (DE3) pLysS. Recombinant AsSS4 protein was obtained after induction by IPTG and SDS-PAGE analysis with a MW of 64 kD. Enzymatic reactions using farnesyl pyrophosphate showed that recombinant AsSS4 protein purified by Ni-agarose gel yielded five sesquiterpene compounds, cyclohexane, 1-ethenyl-1-methyl-2, 4-bis(1-methylethenyl)-, β-elemene, α-guaiene, α-caryophyllene and δ-guaiene. This paper reported the first cloning and functional characterization of AsSS4 gene from A. sinensis, which will establish a foundation for future studies on the molecular mechanisms of wound-induce agarwood formation in A. sinensis
