The major problem of rural water conservancy facilities during its management and maintenance is in the "been used, under no control" state. And the main reasons of this state are the public belonging property, investment by a single subject, and lack of effective supervision and management mechanism. Since rural water conservancy facilities is used in small scale and has the features of rural "acquaintances community", a balanced long-term interest mechanism for the management and maintenance of rural water conservancy facilities is established for interest-related parties. On short-term view, the most effective measure is to bring the operational status of rural water conservancy facilities into the evaluation indicators of the local government.

AIM To examine the medical status of children with biliary atresia(BA) surviving with native *** In this cross-sectional review,data collected included complications of chronic liver disease(CLD)(cholangitis in the preceding 12 mo,portal hypertension,variceal bleeding,fractures,hepatopulmonary syndrome,portopulmonary hypertension) and laboratory indices(white cell and platelet counts,total bilirubin,albumin,international normalized ratio,alanine aminotransferase,aspartate aminotransferase,γ-glutamyl transpeptidase). Ideal medical outcome was defined as absence of clinical evidence of CLD or abnormal laboratory indices. RESULTS Fifty-two children [females = 32,62%; median age 7.4 years,n = 35(67%) older than 5 years] with BA(median age at surgery 60 d,range of 30 to 148 d) survived with native liver. Common complications of CLD noted were portal hypertension(40%,n = 21; 2 younger than 5 years),cholangitis(36%) and bleeding varices(25%,n = 13; 1 younger than 5 years). Fifteen(29%) had no clinical complications of CLD and three(6%) had normal laboratory indices. Ideal medical outcome was only seen in 1 patient(2%). CONCLUSION Clinical or laboratory evidence of CLD are present in 98% of children with BA living with native livers after hepatoportoenterostomy. Portal hypertension and variceal bleeding may be seen in children younger than 5 years of age,underscoring the importance of medical surveillance for complications of BA starting at a young age.

The Nitrogen Vacancy （NV） center is becoming a promising qubit for quantum information processing. The defect has a long coherence time at room temperature and it allows spin state initialized and read out by laser and manipulated by microwave pulses. It has been utilized as a ultra sensi- tive probe for magnetic fields and remote spins as well. Here, we review the recent progresses in experimental demonstrations based on NV centers. We first introduce our work on implementation of the Deutsch- Jozsa algorithm with a single electronic spin in diamond. Then the quantum nature of the bath around the center spin is revealed and continuous wave dynamical decoupling has been demonstrated. By applying dynamical decoupling, a multi-pass quantum metrology protocol is realized to enhance phase estimation. In the final, we demonstrated NV center can be regarded as a ultra-sensitive sensor spin to implement nuclear magnetic resonance （NMR） imaging at nanoscale.

目的:分析近年来深入研究的几种影响局部骨代谢的细胞生长调节因子,通过探讨各种功能性分子间的作用和联系,从功能的角度了解其决定因素和影响因素,试图勾勒出骨细胞生长、存活、发挥功能的局部体液化学微环境。资料来源:应用计算机检索Medline1980-01/2002-12相关骨代谢调节因子的文献,检索词“Bonemetabolism,adjustingfactors”,并限定文献语言种类为English。同时计算机检索CBM1980-01/2002-12相关骨代谢调节因子的文献,检索词为“骨代谢,调节因子”,并限定语言种类为中文。资料选择:对资料进行初审,选取骨代谢调节因子的文献,开始查找全文。纳入标准:①骨代谢。②调节因子。排除标准:综述文献、重复研究、Meta分析类文章。资料提炼:共收集到57篇关于骨代谢调节因子的文献,纳入22篇符合标准的文献。资料综合:众多的激素、因子共同调节成骨细胞和破骨细胞的代谢活动,它们之间有着协同、促进、抑制的复杂关系,并形成网络。骨组织合成多种生长因子,在骨质疏松发病机制中起着重要作用。成纤维细胞生长因子有利于骨质的生长。血小板衍生生长因子在骨折修复过程中起重要作用。骨是转化生长因子β最大的组织来源和储存库。骨形态发生蛋白在骨间质细胞向成骨细胞转化过程、成骨细胞分化过程以及骨发育和骨形成中起着不可替代的作用。白细胞介素主要由吞噬细胞合成,为多肽类物质。推测P物质在骨的纵向生长过程中可能起调控作用。各种骨代谢影响因子均存在于骨组织中,因而任何时候骨细胞的微环境中都不是只出现某一种因子,也即骨组织代谢是由多种因子同时参与调节。结论:针对影响骨代谢各种功能性分子间的复杂网络关系,在微观领域进行分子结构功能模式的数字化、信息化的研究是其可行的途径,也是极其必要的。

高等教育经费不足已经成为制约我国各层次高校建设和发展的最大难题。对于高等教育资金的筹措,目前研究者大多持这样的观点:中国教育的融资渠道应该也必须多元化,才能改变目前高等教育融资渠道单一、经费不足的困境。但相对于目前巨额的经费缺口而言,其他融资规模微不足道,在当前教育体制下,短期内增长潜力有限,难以改善我国高等教育经费短缺的现状。短期内,解决高等教育经费短缺的有效途径仍是加大政府投资力度。
