Moral injury in the war has been taken seriously since it has been gradually raised as an important military psychological problem.War is not the flavor of a quiet life,nor is it the ideal place to achieve the hero dream.Strong battlefield impact and ethical challenges likely cause moral injury to those innocent soldiers.Based on the American classic war films such as“ Closed Island”,“Born on July 4”,“Field Row” and “Snowden”,this paper mainly expounded the ethical thinking off our causes of moral injury including massacre of the prisoners of war,injustice war,betrayal of the senior officer,and hegemonic government.

Objective To analyze the association of staphylococcal nuclease domain-containing protein 1(SND1) and T-cell intracellular antigen 1(TIA-1) on stress granules, and the regulation of SND1 on stress granules under stress stimuli. Methods The immunofluorescence assay and laser scanning confocal microscopy were used to observe the co-localization of SND1 protein and TIA-1 protein under stress stimuli, and the over-expression plasmids of pEGFP vector were transfected into HeLa cells and to verify which domain of SND1 co-localized with TIA-1 under stress stimuli. RNA interference-mediated knockdown of the expression of SND1 protein in HeLa cells was measured by Western Blotting assay. Then whether the knockdown of SND1 affected the recruitment of TIA-1 on stress granules was observed. Heat shocks under different times were used to identify whether there were dynamic changes in transportation of SND1 and TIA-1 on stress granules. Results SND1 co-localized with TIA-1 on stress granules under stress stimuli, and the associated domain of SND1 were SN domain. TIA-1 still can be recruited on stress granules but a large amount of stress granules were reduced even though the expression of SND1 protein was decreased. And the transportation of SND1 on stress granules was laged behind TIA-1 under different-times of heat shocks. Conclusion SND1 protein co-localizes with TIA-1 on stress granules, and which co-regulates the cellular stress response under stress stimuli.

Sanqi is a popular traditional Chinese medicine and commonly used for promoting blood circulation and removing blood stasis. Notoginsenoside R1, ginsenoside Rg1, Re, Rb1 and Rd are the major active constituents of Sanqi. The purpose of the study was to investigate the pharmacokinetic behavior of the five active constituents from total saponin from Sanqi when it was used in the blood stasis animals or in combination with Gegen. The concentrations of the five active constituents in rat plasma were determined by an ultra-HPLC-ESI-MS/MS method. The main pharmacokinetic parameters were calculated and statistically analyzed using the unpaired student's t-test. It was found that the pharmacokinetic parameters of notoginsenoside R1, ginsenoside Rg1 and Rb1 represented a statistically significant difference (Po0.05) between the normal rats and the blood stasis rats after administration of total saponin from Sanqi (TSFS). And there were statistically significant differences (Po0.05) in the pharmacokinetic parameters of all the five constituents between administration of TSFS alone and combined with total flavonoid from Gegen (TFFG) in blood stasis rats. It suggested that the pharmacokinetic behavior of the active constituents from TSFS could be changed when it was used in blood stasis animals or in combination with TFFG.

To ensure the safety of the commercially available chenpi, a convenient and fast analytical method was developed for the determination of 133 pesticide residues in chenpi using gas chromatography-tandem mass spectrometry (GC-MS/MS). In this study, different extraction solvents, redissolution solvents and adsorbents were tested according to the recovery and purification effect to obtain a modified QuEChERS method. The samples were extracted with acetonitrile. During the clean-up step, octadecyl-modified silica (C18) and graphitized carbon black (GCB) were selected, and aminopropyl (NH2) was used instead of primary secondary amine (PSA) because of its weaker ion exchange capacity which had little effect on the recovery of ditalimfos. Samples were quantified by matrix-matched calibration with internal stan-dards. All pesticides showed good linearity in the respective range, both with values of r2 >0.99. The average recoveries of the pesticides spiked samples ranged from 70.0％ to 112.2％ with the RSDs of 0.2％–14.4％. The modified QuEChERS method was validated and applied to twenty real samples. Five pesticides were found in eight batches, but no pesticide exceeded the maximum residue limits (MRL, MRL reference to European commission).
