1Irinotecan therapy and molecular targets in colorectal cancer: A systemic review显示文摘Irinotecan is the second line chemotherapy for advanced stage colorectal cancer (CRC) after failure of first line chemotherapy with oxaliplatin and 5-fluorouracil. The aim of this review is to analyse the data on irinotecan as second line chemotherapy for advanced CRC and the potential roles of the molecular markers, p53 and vascular endothelial growth factor (VEGF) in the management of advanced CRC. Thus, the English literature from 1980 to 2008 concerning irinotecan, p53, VEGF and CRC was reviewed. On review, Phase and clinical trials showed thatirinotecan improves pain-free survival, quality of life, 1-year survival, progression-free survival and overall survival in advanced CRC. p53 and VEGF were expressed in CRC and had a predictive power of aggressive clinical behaviour in CRC. Irinotecan sensitizes p53 wild type, mutant and null cells to Fasmediated cell apoptosis in CRC cells. Wild type p53 cells were more sensitive to irinotecan than mutated p53. Irinotecan has an anti-VEGF effect inhibiting endothelial cell proliferation, increasing apoptosis and reducing microvascular density which is onlylimited by irinotecan toxicity levels. To conclude, irinotecan improves the patient's quality of life and the survival rates of patients with advanced CRC. p53 and VEGF status of the patients' tumour is likely to affect the responsiveness of CRC to irinotecan. It is recommended that studies of the expression of these molecular markers in relation to chemoresponsiveness ofirinotecan should be carried out for better management of patients with advanced CRC.Jessica Weekes Alfred King-Yin Lam Sabe Sebesan Yik-Hong Ho 2009World Journal of Gastroenterology2009,15,29:9

5海南省城镇娱乐场所从业女性对女用安全套的接受性调查显示文摘目的了解娱乐场所从业女性对女用安全套的接受性。方法制定相关的调查问卷,在干预前、中、后分3次对同一地区娱乐场所女性从业人员进行面对面的调查,然后对收集的信息进行比较分析。结果3次调查的样本量分别为158、154及151人,70%左右的从业女性均有商业性性行为,40%以上的人在最近1个月的商业性行为中未使用任何安全套,80%以上的人最近1个月与主要性伴的性行为中未使用任何安全套;96%以上的人对女用安全套的自主防病功能有着一致的认同,使用女用安全套的人数从干预前的1.3%提高到干预中的22.7%和干预后的22.5%,但是对女用安全套外观、使用的简便性等感受性方面的指标,干预后较干预前有所下降。结论娱乐场所从业女性对女用安全套有较为积极的认识,也愿意尝试使用,但若想让该人群广泛接受,女用安全套还需在外观及使用的便捷性方面加以完善。何滨 曾小妹 廖苏苏 冯维平 蔡小丹 王广荣 Margaret Weeks 2010中国热带医学2010,10,3:4
6FSW性行为特征及女用安全套接受意愿调查显示文摘中国艾滋病经异性性传播所占比例已由2008年的40.3%上升到2009年的47.1%,经性传播已成为中国艾滋病传播的主要途径。女性因生物、社会、经济、文化等因素影响,其感染艾滋病的机率为男性的2.5-8倍。女性性服务工作者(fe-male sex workers,FSW)因其高危行为发生频率高、性病感染率高、流动性强、男用安全套使用率低等特点,成为艾滋病由高危人群向普通人群传播的桥梁。为探索更多被女性接受的艾滋病性病预防方法,于2010年3-8月对海南省琼海市高、中、低档娱乐场所中的FSW进行女用安全套接受性调查,现将结果报告如下。何滨 宣冬青 曾庆梅 林友淑 吴彩蝶 李瑞颖 廖苏苏 Margaret Weeks 李江虹 2012中国公共卫生2012,28,10:3

8Toward a socio-political approach to water management: successes and limitations of IWRM programs in rural northwestern China显示文摘In rural north-western China,the tension between economic growth and ecological crises demonstrates the limitations of dominant top-down approaches to water management.In the 1990s,the Chinese government adopted the Integrated Water Resources Management(IWRM)approach to combat the degradation of water and ecological systems throughout its rural regions.While the approach has had some success at reducing desertification,water shortage,and ecological deterioration,there are important limitations and obstacles that continue to impede optimum outcomes in water management.As the current IWRM approach is instituted through a top-down centralized bureaucratic structure,it often fails to address the socio-political context in which water management is embedded and therefore lacks a complete treatment of how power is embedded in the bureaucracy and how it articulates through economic growth imperatives set by the Chinese state.The approach has relied on infrastructure heavy and technocratic solutions to govern water demand,which has worked to undermine the focus on integration and public participation.Finally,the historical process through which water management mechanisms have been instituted are fraught with bureaucratic fragmentation and processes of centralization that work against some of its primary goals such as reducing uncertainty and risk in water management systems.This article reveals the historical,social,political,and economic processes behind these shortcomings in water management in rural northwestern China by focusing on the limitations of a top-down approach that rely on infrastructure,technology,and quantification,and thereby advances a more holistic,socio-political perspective for water management that considers the state-society dynamics inherent in water governance in rural China.KuoRay MAO Qian ZHANG Yongji XUE Nefratiri WEEKS 2020Frontiers of Earth Science2020,14,2:3

13Molecular phylogenetic analysis of Leibnitzia Cass.(Asteraceae:Mutisieae:Gerbera-complex),an Asian-North American disjunct genus显示文摘Leibnitzia comprises six species of perennial herbs that are adapted to high elevation conditions and is one of only two Asteraceae genera known to have an exclusively disjunct distribution spanning central to eastern Asia and North America.Molecular phylogenetic analysis of Leibnitzia and other Gerbera-complex members indicates that Leibnitzia is monophyletic,which is in contrast with our expectation that the American Leibnitzia species L. lyrata and L.occimadrensis would be more closely related to another American member of the Gerbera-complex,namely Chaptalia.Ancestral area reconstructions show that the historical biogeography of the Gerbera-complex mirrors that of the entire Asteraceae,with early diverging lineages located in South America that were followed by transfers to Africa and Eurasia and,most recently,to North America.Intercontinental transfer of Leibnitzia appears to have been directed from Asia to North America.Independent calibrations of nuclear(ribosomal DNA internal transcribed spacer region)and chloroplast(trnL-rpl32 intron)DNA sequence data using relaxed clock methods and either mean rate or fossil-based priors unanimously support Miocene and younger divergence times for Gerbera-complex taxa.The ages are not consistent with most Gondwanan vicariance episodes and,thus,the global distribution of Gerbera-complex members must be explained in large part by long-distance dispersal.American species of Leibnitzia are estimated to have diverged from their Asian ancestor during the Quaternary(ca.2 mya)and either migrated overland to North America via Beringia and retreated southwards along high elevation corridors to their present location in southwestern North America or were dispersed long distance.Kristen E.BAIRD Vicki A.FUNK Jun WEN Andrea WEEKS 2010Journal of Systematics and Evolution2010,48,3:2
14Quantifying cold front induced water transport of a bay with in situ observations using manned and unmanned boats显示文摘The generation of high-resolution data is increasingly important in understanding the complexities of coastal ocean and developing sound management strategies, especially in view of the long-term impact of severe weather systems. The impact of severe weather systems, when integrated over time, can be significant when compared with tidal oscillations. This paper presents a study of water transport out of Vermilion Bay in response to a short,intense event associated with a passing atmospheric cold front, and reports the application of an Acoustic Doppler Current Profiler(ADCP) mounted on an Automated Surface Craft(ASC), known as the auto-boat or unmanned boat, developed in our lab at the Louisiana State University, to generate high resolution data accurately at a fraction of the cost of a manned boat. In our study, we used a manned boat and an unmanned boat, each for over 24 h to cover an entire diurnal tidal cycle, to measure flow velocity profiles to calculate the total transport. A stationary ADCP was deployed in the Southwest Pass of the Vermilion Bay from May 2009 to April2012, providing data almost continuously(with only one major gap), with a 717-day record of water transport between the northern Gulf of Mexico and Vermilion Bay, and demonstrates the importance of the pass in water transport.WEEKS Eddie ROBINSON Mark E LI Chunyan 2018Acta Oceanologica Sinica2018,37,11:2
