Methods: The expression of NF-КBP65 and BCL-2 protein in pa-raffin embedded specimens of pleomorphic adenoma and adjacent normal salivary gland tissue of 20 cases was detected using immunohistochemical S-P method. Results: The positive rates of NF-КBP65 expression in pleomorphic adenoma and adjacent normal salivary gland tissue were? 55% and 10%, and the positive rates of BCL-2 expression were 35% and 10% respectively. The differences of NF-КBP65 and BCL-2 expression in pleomorphic adenoma and tumor adjacent normal salivary gland tissue were statistically significant (P < 0.05).

基于Copula函数的东江流域水文干旱特征分析

Abstract: 东江流域肩负着给珠三角及其周边城市与香港供水的重要任务,水文干旱特征的研究对于东江流域供水的不确定性及可持续性研究具有重要意义。基于此,本文利用Copula函数及第二重现期等方法对东江流域4个水文站1975~2009年的日流量数据进行了分析。研究结果表明,在东江流域,同时发生较高干旱强度与较长历时的干旱事件的风险由上游向下游逐渐减小;而发生较高干旱强度或较长干旱历时的干旱事件风险在上游最小,随着干旱强度或历时增大到一定程度,下游的风险相对降低。在进行水资源管理时,应将流域作为一个整体,全面考虑水文干旱风险在东江流域上中下游的异同,该文的研究对于东江流域水资源管理具有重要理论与现实意义
Variations of hydrological droughts largely decide the variability and availability of water resources of a river basin. The EastRiver basinbears the heavy responsibility for water supply for the megacities within the Pearl River Delta region and those in the vicinity of the Pearl River Delta such as Shenzhen andHong Kong. About 80% of the water consumption of Hong Kong has to be satisfied by the water supply from theEast River. In this case, the sustainable water supply from theEastRiver basinwill be greatly significant for the regional social stability. In this study, statistical behaviors and risks of the hydrological droughts of the East River basin are evaluated using copula functions and the secondary return periods based on the daily streamflow data covering the period of 1975-2009. The research results indicate that the hydrological droughts of high drought severity and long duration are subjected to the decreasing risks from the upper to the lower East River basin. However, the droughts of higher severity or long duration are subjected to the lower risk in the upperEastRiver basinwhen compared to those in the lowerEastRiver basin. Water resources management of theEastRiver basinshould be integrated by taking theEastRiver basinas a whole. And the results of this study will provide theoretical and scientific grounds for the basin-scale water resources management.

Abstract: 采用草鱼生长激素夹心式酶联免疫吸附测定法(ELISA),研究了重组鲤生长激素(rcGH)经胃或肠灌注后,胡子鲶、大口鲶和银鲫血清GH水平的变化规律。胡子鲶、大口鲶直肠分别灌注rcGH(1μg/g和5μg/g)后,血清GH水平迅速升高,而在对照组胡子鲶和大口鲶血清中未检测到内源性的GH,预示处理组血清GH水平的迅速升高是由rcGH从小肠内转移进血液引起的。胡子鲶胃内灌注rcGH(25μg/g)后,在

Abstract: 调查踏勘及观测估算表明,本区除大湖融区外,多年冻土连续分布,其厚度变化在20—100m,表层最大融化深度0.5—1.8m不等,主要取决于地貌单元、雪盖厚度与持续历时,土质及水分状况。小山包顶上发育着30cm厚的地下冰层及高15cm的冰楔。多年冻土层中还存在融化夹层。

我国土冻胀研究进展

冰川冻土 , 1988,
Abstract: 土之冻胀,是由于土温降至冰点以下,土体原孔隙中部分水结冰体积膨胀,以及更主要的是在土壤水势梯度作用下未冻区的水分向冻结前缘迁移、聚集,并冻结体积膨胀所致。在自然条件下,地基土及土工构筑物本身土质、水文及冻结条件的不均一性,造成建筑物的不均匀冻胀变形而不能正常运行、甚至破坏,或者即使在冻结时尚能运行,一俟融化便丧失承载能力而破坏。凡上述种种,通常称为冻胀破坏。简称冻害。综观寒区工程,可以断言土之冻胀作用是季节冻土区各种工程产生冻害的主要原因,也是造成多年冻土区建筑物冻害的主要原因之一。
