Impact of vegetation restoration on hydrological processes in the middle reaches of the Yellow River,China

Forestry Studies in China 2009年第4期11卷 209-218页

作者： xin zhong-bao YU xin-xiao Key Laboratory of Soil and Water Conservation and Desertification Combating of the Ministry of Education Beijing Forest Univer-sity 100083 P. R. China

Sediment discharge from the Yellow River originates mainly from the drainage area between Hekouzhen and Longmen, i.e., the Helong area. Spatial-temporal variations of the vegetation cover in this area during the 1981-2007 period have been investigated using GIMMS and SPOT VGT NDVI data. We have also analyzed the interannual variations in vegetation cover and changes in annual runoff and sediment discharge, the consequences from precipitation change and the Grain for Green Project （GGP）. The results show that vegetation cover of the Helong area has increased during the 1981-2007 period. The northwestern part the Helong area, where the flat sandy lands are covered by grass, has experienced the largest increase. The region where the vegetation cover has declined is largely found in the southern and southeastern Helong area, which is a gullied hilly area or forested. Although precipitation was relatively low during the 1999-2007 period, the vegetation cover showed a significant increase in the Helong area, due to the implementation of the GGP. During this period, the most significant improvement in the vegetation cover occurred mainly in the gullied hilly areas of the Loess Plateau, such as the drainage basins of the Kuyehe and Tuweihe rivers and the middle and lower reaches of the Wudinghe and Yanhe rivers. A comparison of the average annual maximum NDVI between the earlier （1998-2002） stage and the next five years （2003-2007） of the GGP indicates that the areas with increases of 10% and 20% in NDVI account for 72.5% and 36.4% of the total area, respectively. Interannual variation of annual runoff and sediment discharge shows a declining trend, especially since the 1980s, when the decrease became very obvious. Compared with the 1950-1969 period, the average runoff during the 1980-2007 period was reduced by 34.8 × 10^8 m3 and the sediment discharge by 6.4 ×10^8 t, accounting for 49.4% and 64.9% of that in the 1950-1969 period, respectively. There is a positive correlati

Biomedical and Environmental Sciences 2006年第6期19卷 495-497页

作者： HONG DAI HUI XUE ZONG-JIE YIN and zhong-xin xiao School of Public Health and Family Medicine Capital Medical University You An Men Beijing 100069 China National Medical Examination Center The Ministry of Public Health Xi Zhi Men Beijing 100044 China

Purpose To explore the needs for basic community-based rehabilitation services for disabled persons in Xuanwu District, Beijing, China, and to identify factors which influence disabled persons to accept rehabilitation services. Method One hundred and eight disabled persons were selected by systematic sampling and simple random sampling to assess their needs for community-based rehabilitation services. Results Of the interviewees, 57A% needed the community-based rehabilitation services, but only 13.9% took advantage of it. The main factors influencing the interviewees to accept these services were cost （P〈0.05）, knowledge about rehabilitation medicine （P〈0.05）; and the belief in the therapeutic benefit of the community-based rehabilitation service （P〈0.05）. Conclusion A considerable gap exists between the supply of community-based rehabilitation services in Beijing and the needs for these services by disabled residents underscoring the need for improved availability, and for additional research.

如何界定缅甸缅族社会结构,人类学界一直存在争议。一种观点认为缅族社会结构最突出的特征是阶序分明、等级森严;另一种观点则极力强调缅族社会中高度平等与个人主义的特点。通过在缅甸长期的田野调查发现,缅族社会结构兼具"强礼仪"与"弱依附"的双重特征,社会成员依照严格固化的礼仪体系进行社会互动,但社会成员之间没有形成强烈的依附关系。弱依附是缅族社会结构的首要特征,缅族社会中的礼仪体系并非是划分身份和等级的工具,而是弱依附社会中的社会整合策略。

人类学强调整体性的研究视角使其对日常生活有着特殊的关怀,相信诸多社会与文化的事项总是会在日常生活中显现出来,而日常生活的改变同时也意味着社会与文化层面的变迁。本文关注云南省元阳县哈尼族箐口村的旅游开发对于村落日常生活的影响,试图指出在旅游开发的过程中,村落日常生活发生了异化,即镶嵌于整体的社会文化体系中的日常生活在不断消解,以经济为基础和目的的单面向日常生活在不断扩张,也即日常生活与社会文化体系的脱嵌,而村落日常生活异化的背后是社会与文化的变迁与重构。通过这一实例,本文试图探讨现代性与日常生活之间的相互关系。

2011年,在缅甸持续了半个世纪之久的军人专政宣告结束,国家政治转型取得了实质性的进展,在此过程中,多党制和普选制的规则得以确立并逐步完善,民主政治的框架初见雏形。国家政治转型为缅甸乡村社会带来了深刻的变化,变化的领域囊括了乡村政治、经济与社会文化等各个方面。缅甸乡村社会在政治转型中呈现出新的面貌,但这一重要的课题在学界还未得到应有的关注。通过在缅甸乡村社会中长期的田野调查,本文发现军政府时代之后的缅甸乡村社会出现了许多新的情况,具体的变化主要包括村落共同体的裂变、乡村权力结构的转型、村民与国家关系的变迁,等等。概而言之,在过去的10年,缅甸乡村政治生活的主旋律逐渐从“抗争政治”向“派别政治”转型。

南传佛教在缅甸已有一千多年的历史,曾被尊崇为缅甸国教,传承至今,南传佛教仍深刻地影响着缅甸的社会文化与日常生活。本文采用田野调查的研究方法,通过对四个不同类型的缅甸寺庙进行人类学考察,从而进一步对当代缅甸南传佛教的形态进行类型学的探讨,认为以维系集体情感为核心的社区佛教、以个体心理治愈为核心的禅修佛教、以扶助弱者为核心的慈善佛教、以培养僧人为核心的教育佛教是当代缅甸佛教的四种核心形态。这四种佛教形态具有不同的性质和功能,并以不同的方式与缅甸社会文化的各个方面紧密联系在一起,这成为南传佛教在缅甸得以不断传承和发展的基础。

Tumor inflammation-specific self-amplifying fluorescent molecular probes induce an anti-tumor immune response

Science China Chemistry 2025年第1期68卷 273-287页

Enhancing the concentration of exogenous molecular drugs within the tumor microenvironment through enzyme-catalyzed polymerization presents a novel strategy for cancer therapy. Nonetheless, the optimization of the catalytic efficiency is often impeded by the inefficient expression of enzymes. Herein, we reported a self-amplifying fluorescent molecular probe, Bis-HTPICG, for photodynamic therapy(PDT) and subsequent PDT-induced immunoreaction. The Bis-HTP-ICG probe possesses a noticeable enzyme-catalyzed polymerization facilitated by myeloperoxidase(MPO), a crucial enzyme secreted by neutrophils at inflammation sites. Upon exposure to laser irradiation, Bis-HTP-ICG showed a high PDT efficacy, inducing an acute inflammatory response that stimulates further recruitment of neutrophils and then elevated MPO secretion. The heightened level of MPO enhances the accumulation of the Bis-HTP-ICG via self-polymerization or binding with intratumoral proteins following MPO enzyme catalysis, instigating a self-amplifying chain reaction cycle involving Bis-HTP-ICG, neutrophils and ***, PDT efficiently incites immunogenic cell death(ICD) in tumor cells, initiating an anti-tumor immune response including dendritic cells(DCs) maturation, T cell proliferation and reprogramming of tumor-associated neutrophils(TANs). This work portrays a promising strategy for self-amplification of fluorescent molecular probes through adjustable enzyme levels,potentially offering a unique avenue to enhance the tumor accumulation of molecular drugs for improved tumor therapy.
