Objective To investigate the effect of nitric oxide synthase(NOS) inhibitors and L-arginine(L-Arg) on the prognosis of traumatic shock in rats. Methods Traumatic shock models of Sprague-Daulay rats were made and randomly devided into control group (n=24),L-NAME treatment group (n=24),AG treatment group (n=24) and L-Arg treatment group (n=24). Serum nitric oxide(NO) levels and oxygen partial pressure in tissues include skeletal muscles,liver and small intestine were detected at 1h,3h,5h after resuscitation. Meanwhile, hemodynamic data of the rats and their survival rates of 12h and 24h were monitored and recorded. Results Serum NO concentration was statistically lower after resuscitation in L-NAME group than that in control group, while there were no statistical significance of tissues oxygen partial pressure and survival rate in 12、24h between the two groups. AG could decrease serum NO levels only at late stage of traumatic shock,but no effect on the synthesis and relase of NO at early stage of traumati shock.AG could improve tissues oxygen partial pressure of the liver and small intestine, and prolonged the mean survival time. L-Arg could increase serum NO levels, and improve oxygen partial pressure of intestine and significantly increase the survival rate at 12h and 24h in rats with traumatic shock. Conclusions Treatment with AG and L-Arg can improve the prognosis of traumatic shock rats much better than that with L-NAME.

Aim Toinvestigatetheeffectsoftriptonot-erpene methyl ether ( TME ) , a diterpene derived from the medicinal plant Triptergium wilfordii, on human gastric cancer AGS cell proliferation inhibition and ap-optosisinducedinvitro.Methods MTTassaywas used for screening tumor spectrum and detecting the vi-ability of AGS cells and normal human gastric epitheli-al cells GES-1 . Cell morphology was observed by light microscopy and AO / EB staining. Flow cytometry was used to detect cell apoptotic rate and cell cycle. JC-1 staining and fluorescence probe DCFH-DA were em-ployed to detect the changes of mitochondrial mem-brane potential and reactive oxygen species ( ROS ) . The effect of inhibiting AGS clonogenic survival was as-sayed by the method of plate clone formation. Western blot was used to analyse the expression of caspase-3 , caspase-8,Bcl-2andBax.Results MTTresults showed that TME exhibited significantly higher cytotox-icity to gastric cancer AGS cell line than to noncancer-ous cell line GES-1. IC50 for AGS of 48 h treatment was 23 . 85 μmol · L-1 . TME significantly inhibited colony formation and caused morphological changes in AGS cells. Annexin V-FITC / PI double staining showed the apoptotic rate increased. DCFH-DA stai-ning showed TME resulted in an increase in intracellu-lar ROS levels. Mitochondrial membrane potential de-creased after TME treatment. Western blot results showed that TME increased the proportion of Bax /Bcl-2 , with the activation of caspase-8 and caspase-3 . The broad-spectrum caspase inhibitor z-VAD-fmk pre-treatment reduced the expression of caspase-8 and caspase-3. TME enabled AGS cell cycle arrest in G0/G1phase.Conclusion TMEpossessespotenttumor selected toxicity and can induce apoptosis of AGS cells through cell cycle arrest, which is associated with Bcl-2 protein family.
