Background Rapid reexpansion of collapsed lungs leads to reexpansion pulmonary edema （RPE）. We aimed to investigate the effect of melatonin in the prevention of RPE formation. Methods We used a Wistar rat model in which the left lung was collapsed by ligating the left bronchus for 48 hours and then reexpanded and ventilated for an additional 2 hours. Thirty minutes before reexpansion, we injected melatonin （10 mg/kg） or vehicle intraperitoneally. We compared the wet/dry ratio, oxygenation index, myeloperoxidase （MPO） activity, nitric oxide （NO）, malondialdehyde （MDA） and interleukin 8 （IL-8） levels in the reexpanded lungs between untreated and treated animals. Results We found that the wet/dry ratio of the melatonin group was significantly lower than that of the vehicle group, and the oxygenation index was higher in the melatonin group. Compared with the control, melatonin pretreatment significantly decreased the activities of IL-8, NO, MDA levels and MPO in lung tissues. Histopathology of reexpanded lungs showed that the melatonin pretreatment group had less pulmonary edema and less inflammatory cell infiltration. Conclusion Melatonin decreases pulmonary edema and improves oxygenation after reexpansion by attenuating oxidative stress and inhibiting pro-inflammatory cytokines.

The local structure and thermophysical behavior of Mg-La liquid alloys were in-depth understood using deep potential molecular dynamic(DPMD) simulation driven via machine learning to promote the development of Mg-La alloys. The robustness of the trained deep potential(DP) model was thoroughly evaluated through several aspects, including root-mean-square errors(RMSEs), energy and force data, and structural information comparison results;the results indicate the carefully trained DP model is reliable. The component and temperature dependence of the local structure in the Mg-La liquid alloy was analyzed. The effect of Mg content in the system on the first coordination shell of the atomic pairs is the same as that of temperature. The pre-peak demonstrated in the structure factor indicates the presence of a medium-range ordered structure in the Mg-La liquid alloy, which is particularly pronounced in the 80at% Mg system and disappears at elevated temperatures. The density, self-diffusion coefficient, and shear viscosity for the Mg-La liquid alloy were predicted via DPMD simulation, the evolution patterns with Mg content and temperature were subsequently discussed, and a database was established accordingly. Finally, the mixing enthalpy and elemental activity of the Mg-La liquid alloy at 1200 K were reliably evaluated,which provides new guidance for related studies.

Two C16H12O4 isomers of derivatives of pagodane were firstly reported and studied by using DFT method. Geometries, energies, and vibrational frequencies have been calculated for the two C16H12O4 isomers with pagodane-like structures at the B3LYP/6-31G^＊＊ level of theory. Symmetries of isomer 1 and 2 are D2h and D2d, respectively. Heats of formation for the two C16H12O4 isomers have been estimated in this paper. According to the heats of formation, the two C16H12O4 isomers are more stable than pagodane. Heats of formation as well as the vibrational analysis indicate that the two C16H12O4 isomers enjoy sufficient stability to allow for the experimental preparation.

为了探讨苦马豆素通过消化系统对家兔脾脏免疫功能和代谢的影响,将体重为(1.9±0.12)kg的24只家兔随机分成对照组与试验组,每组雌、雄各半。试验组家兔饲喂含有小花棘豆的自制颗粒饲料,饲喂苦马豆素剂量为2 mg/(kg·d),对照组家兔饲喂自制颗粒饲料中不含小花棘豆。所有家兔单笼饲养,自由饮水,每天观测并记录家兔的健康状态。在试验的第60天,采取所有家兔脾脏,对脾脏进行基于iTRAQ的定量蛋白质组学分析、生物信息学分析及关键蛋白质的Western blot验证。结果显示,所有试验组家兔均呈现明显的中毒现象。与对照组相比,共鉴定出315个与新陈代谢(81%)及免疫相关(15%)的差异表达蛋白质(>1.5倍或<1/1.5倍)。而且,苦马豆素中毒家兔脾脏细胞分解代谢处于激活状态,但其免疫反应处于抑制状态。说明苦马豆素抑制了家兔脾脏的免疫功能,激活了脾脏组织的分解代谢。
