了解东北虎(Panthera tigris altaica)的历史分布和数量动态对加速虎栖息地连通,恢复历史分布区,促进中俄共同保护野生东北虎集合种群具有重要的指导意义。20世纪初期,东北虎曾分布在俄罗斯远东地区南部、朝鲜半岛、中国长白山脉和松花江流域,数量近3 000只。猎捕和栖息地丧失导致东北虎数量急剧下降。20世纪40年代,远东地区东北虎数量仅剩锡霍特山脉中部的20~30只。20世纪中期以后,苏联政府采取了东北虎禁猎、禁捕令、扩大保护地和边境管控等综合保护措施,解除了东北虎的濒危状态,促进了种群复苏和分布区扩大。2015年俄罗斯东北虎种群数量恢复到523~540只,呈现稳步向中俄边境扩展之势。俄罗斯在原生态完好、食物丰富和人为干扰少的东北虎西北历史分布区,将野外救助的幼虎野化放归大自然,建立了稳定的东北虎小型种群,这项试验对于拓展大型猫科动物种群分布区具有重要国际意义。21世纪初,东北虎在中国总数减少到十余只。2017年,中国开展东北虎豹国家公园试点,通过整合自然保护地,东北虎处境开始好转,种群恢复刚刚走出低谷,呈现增长态势,当前的主要工作任务是:一方面优化整合自然保护地,畅通跨界生态廊道,加快边境区东北虎向中方迁徙扩散,壮大中国东北虎繁殖种群; 另一方面实施东北虎野化放归计划,突破幼虎野化训练技术瓶颈,在历史分布区创建新的东北虎野外繁殖种群。

Objective To investigate the effect of roflumilast on pulmonary injury induced by Streptococcus pneumonia (SP) in rat model. Methods Rats were randomly divided into control group, pneumonia model group, roflumilast low dose group, high dose group and roflumilast high dose plus Colivelin (STAT3 activator) intervention group. The level of PaO2, PaCO2, IL-1β, IL-8, IL-10 and TNF-α were detected. Lung tissue wet/dry ratio (W/D), MDA content, MPO and SOD activity were examined. HE staining microscopy was used to observe the pathological injury of lung tissue. Apoptosis, cleaved caspase-3, IL-6, and p-STAT3/STAT3 protein expression were detected. Results Compared with the control group, the lung tissue of animals in the model group showed obvious damage; blood PaO2, oxygenation index (OI), lung tissue IL-10 level, and SOD activity were all significantly reduced; the level of blood PaCO2, lung tissue IL-1β, IL-8, TNF-α and W/D values, MDA content, MPO activity, cell apoptosis rate, cleaved caspase-3, IL-6, and p-STAT3/STAT3 protein expression were significantly increased (P<0.05). Compared with the model group, the lung tissue damage of rats in the low and high dose groups of roflumilast was obviously reduced; the level of blood PaO2, OI and, lung tissue IL-10, and SOD activity were obviously increased, the level of blood PaCO2, lung tissue IL-1β, IL-8, TNF-α and, W/D values, MDA content, MPO activity, cell apoptosis rate, cleaved caspase-3, IL-6, and p-STAT3/STAT3 protein expression were significantly reduced (P<0.05); Colivelin was able to partially reverse the improvement effect of roflumilast on lung injury in rats with SP pneumonia (P<0.05). Conclusions Roflumilast may inhibit inflammatory response, oxidative damage and apoptosis of SP-induced pneumonia in rats resulting in an improvement of lung function. [ABSTRACT FROM AUTHOR]

PROTON transfer reactions , *MASS spectrometry , *ELECTRON impact ionization , *CHEMICAL processes , *ATMOSPHERIC aerosols - Abstract
Atmospheric organic aerosols consist of both gas-phase organic compounds and particle-phase organic compounds. The components of aerosol particles (solid or liquid droplets) can undergo exchange or chemical reactions with gas-phase components, influencing atmospheric physical and chemical processes and potentially impacting atmospheric environment, climate, and human health. Methods for detecting organic compounds in aerosol particle phase are classified into offline and online detection. Offline detection methods involve collecting aerosol samples for analysis using chromatography-mass spectrometry, which is time-consuming and limited sensitivity. Online detection methods involve enriching aerosols through aerodynamic lens and then detecting them using laser ablation or electron impact ionization techniques. However, these methods usually generate a large number of ion fragments, making mass spectrum analysis difficult. Therefore, it is necessary to develop an online detection method for aerosol particle-phase organic compounds with soft ionization and high sampling efficiency. In the present work, a set of aerodynamic lens sampling systems was designed and developed for online detection and analysis of organic compounds in aerosol particle phase. This sampling system consists of a gas-phase stripping module for removing gas-phase organic compounds, an aerodynamic lens module for particle focusing and enrichment, and a thermal desorption module for extracting particle-phase organic compounds. The efficiency of gas-phase organic compound removal and the particle transmission rate of the gas-phase stripping module were firstly investigated. The results showed that gas-phase stripping module achieves a removal efficiency of 98.89% for gas-phase organic compounds, and the particle transmission rate ranges from 75.16% to 91.15% for particles with the diameters between 295 and 375 nm. Subsequently, the effectiveness of the aerodynamic lens was studied through theoretical simulations. The simulation results indicated that the transmission rate of particles in the diameters of 0.36-6.0 μm is above 90% in the designed aerodynamic lens. Finally, The designed aerodynamic lens sampling system with a homemade proton transfer reaction mass spectrometer (PTR-MS) was integrated to develop an aerodynamic lens-PTR-MS device. This device was tested by detecting simulated aerosol samples containing reaction products of α-pinene and ozone. The mass spectrometry results demonstrated that the intensity changes of the examined ten ions are closely related to the presence of α-pinene, confirming that the device can achieve online detection of organic compounds in aerosols ranging from submicron to several micrometers.
