快感缺失是抑郁症的核心症状之一,而多巴胺能系统在快感缺失中发挥关键作用。多巴胺能活动十分复杂,受多种大脑结构调节,包括海马体的腹侧下神经带、伏隔核、腹侧苍白球和基底外侧杏仁核等。基础研究和临床研究表明抑郁症中多巴胺能系统缺陷,而这些缺陷可能源于传入回路的失调。本文从抑郁症与多巴胺能系统的联系入手,总结腹侧被盖区多巴胺能神经元的上游通路,包括腹侧海马下托至伏隔核到腹侧苍白球的激活通路和基底外侧杏仁核至腹侧苍白球的抑制通路,并利用基础实验及临床研究客观阐明抑郁样行为及抑郁症中脑多巴胺能系统传入调节的异常,概述了抗抑郁治疗与中脑多巴胺能神经系统的相关性,以期为抑郁症的诊疗和机制的研究提供思路。

In the upper reaches of Yangtze River and other rivers of southwestern China, the debris flows develop and lead to most serious disasters because of the various landforms, complex geological structures and abundant rainfall. The distribution of debris flows has regularity in the regions with different landform, geological structure, and precipitation. The regularities of distribution of debris flows are as following：（1） distributed in transition belts of different morphologic regions; （2） distributed in the area with strong stream trenching; （3） distributed along fracture zones and seismic belts：（4） distributed in the area with abundant precipitation; （5） distribution of debris flow is azonal. The activity of abundant debris flows not only brings harm to Towns, Villages and Farmlands, Main Lines of Communication, Water-Power Engineering, Stream Channels etc., but also induces strong water and soil loss. According to the present status of debris flow prevention, the problems in disasters mitigation and soil conservancy are found out, and the key works are brought up for the future disasters prevention and soil conservancy.

Human settlements are embedded in traffic networks with hierarchical structures. In order to understand the spreading mechanism of infectious diseases and deploy control measures, the susceptible-infected-removed spreading process is studied with agents moving globally on the hierarchical geographic network, taking into account agents’ preference for node layers and memory of initial nodes. We investigate the spreading behavior in the case of global infection under different scenarios, including different directions of human flow, different locations of infection source, and different moving behaviors of agents between layers. Based on the above-mentioned analysis, we propose screening strategies based on layer rank and moving distance, and compare their effects on delaying epidemic spreading. We find that in the case of global infection,infection spreads faster in high layers than in low layers, and early infection in high layers and moving to high layers both accelerate epidemic spreading. Travels of high-layer and low-layer residents have different effects on accelerating epidemic spreading, and moving between high and low layers increases the peak value of new infected cases more than moving in the same layer or between adjacent layers. Infection in intermediate nodes enhances the effects of moving of low-layer residents more than the moving of high-layer residents on accelerating epidemic spreading. For screening measures, improving the success rate is more effective on delaying epidemic spreading than expanding the screening range. With the same number of moves screened, screening moves into or out of high-layer nodes combined with screening moves between subnetworks has better results than only screening moves into or out of high-layer nodes, and screening long-distance moves has the worst results when the screening range is small, but it achieves the best results in reducing the peak value of new infected cases when the screening range is large enough.

The cereal cyst nematode（CCN, Heteroder aavenae） causes serious yield loss on cereal crops, especially wheat, worldwide. Daxing population in Beijing City and Huangyuan population in Qinghai Province, China, are two CCN populations. In this study, the CCN pathotypes of Daxing and Huangyuan populations were characterized by tests on 23 standard ＂International Test Assortment＂ with the local species Wenmai 19 as the susceptible control. Tested materials were grouped by three nematode populations＇ virulence on resistant genes（Rha1, Rha2, Rha3, Cre1） and nonresistant genes, varieties and lines. Both Daxing and Huangyuan populations were avirulent to Ortolan（Ha1）. Barley cvs. Ortolan, Siri, Morocco, Bajo Aragon 1-1, and Martin 403-2 were all resistant to both populations. Cultivars Herta, Harlan 43 and wheat Iskamish-K-2-light were all susceptible to Huangyuan population, all of them, however, were resistant to Daxing population. The other five oats were all resistant to the two tested CCN populations. Except Iskamisch K-2-light, all the other wheat cultivars（Capa, Loros×Koga, AUS 10894, and Psathias） were susceptible to Daxing population. Because the pathotypes of the two tested CCN populations in Beijing and Qinghai were not identical to any of the 13 pathotypes previously characterized by the test assortment, we classified Daxing and Huangyuan populations as the new pathotypes, named Ha91.

实验上发现,邻炔基酚与芳基重氮盐在热催化和光催化条件下反应可生成不同的产物,然而反应机理尚不清晰.本文采用MSCASPT2和密度泛函理论方法研究了热和光驱动反应的催化机理.结果表明,热催化和光催化反应的初始历程相同,都是在HCO3-协助下由Au(Ⅰ)催化剂和邻炔基酚反应得到乙烯基Au(Ⅰ)中间体.在此过程中,Au(l)催化剂与邻炔基酚反应克服14.8 kcal/mol的能垒生成结构扭曲的配合物,此时邻炔基酚的C≡C三键被活化.随后,乙烯基Au(Ⅰ)中间体和芳基重氮盐形成复合物,热催化和光催化反应开始分叉.在黑暗条件下,反应克服15.7 kcal/mol的能垒后生成最终的热催化产物,此时芳基重氮盐的末端N原子直接与乙烯基Au(Ⅰ)中间体的C原子成键.在光照条件下,复合物首先弛豫到激发单重态,经9.8×10^(9)s^(-1)的高效系间窜跃过程衰变到T_(1)态.在T_(1)态,克服7.8 kcal/mol的能垒完成脱氮反应,产生与乙烯基Au(Ⅰ)中间体的Au原子具有相互作用的芳基自由基,随后发生系间窜跃过程到达基态.在基态形成最终的光催化产物.本研究为理解Au(Ⅰ)催化剂与芳基重氮盐的热催化和光催化反应提供了重要的机理见解,发现了无辐射跃迁在光催化反应中的关键作用.
