Abstract:
前列腺肿瘤(prostate cancer, PCa)作为常见的老年男性肿瘤疾病,发病率正在逐年上升,细胞连接蛋白(Connexon, Cx)的表达异常是其发生机制之一。研究表明前列腺肿瘤细胞较前列腺上皮表达Cx43明显降低,存在细胞间隙连接通讯(GJIC)缺陷,故Cx43表达缺陷可能在前列腺肿瘤发生发展过程中发挥一定作用。研究发现茶多酚类物质,含硒类物质、激素类物质、维生素类、生物碱类等多种化学物质都对前列腺肿瘤细胞Cx43的表达有影响,进而影响前列腺肿瘤发展状况,故本文将对多种化学因素对前列腺肿瘤细胞连接蛋白Cx43的影响及治疗意义作一综述。
Prostate cancer is a common cancer disease within older male populations and its incidence rate increased year by year. The abnormal exception of connexon is one of its pathogenesis. Researches show that Cx43 expression in prostate cancer was effectively lower compared with prostate epi-thelial, what’s more, there existed a gap junctional intercellular communication defects in prostate cancer. So, Cx43 expression defects may significantly affect the prostate cancer process. Researches also show that tea polyphenols substances, selenium substances, hormone-like substances, vitamins, alkaloids, and other chemical substances are also have different levels of effects on the expression of Cx43 in prostate tumor cells. Therefore, they also influenced the development of prostate cancer. So, the following article will mainly state the effecting of variety chemical factors on Cx43 in prostate cancer cells and therapeutic implications.
权力分享与协商民主:中国参与式预算的制度困境与完善路径
Power Sharing and Consultative Democracy: The Dilemma and Consummation of the Participatory Budget

Abstract: 强化政府受托责任、推动基层民主实现以及弥补政府有限理性的现实需求是参与式预算赖以生存的逻辑起点,参与式预算的实质在于实现预算治理主体的多元化,让民众参与预算决策并分享预算权力。当前我国地方政府关于参与式预算存在制度规范化不足、预算主体资格与能力受限、参与的广度深度有限、参与的形式单一等问题。因此,参与式预算应当从推进预算参与的制度化、建构预算参与的适格主体、扩大公众参与预算的范围以及规范预算参与的程序与方式等方面予以完善,以确保实现预算共同治理目标。
The vital logical basis of participatory budget is the realistic demand for strengthening government accountability, promoting grassroots democracy and making up for the government's limited rationality.The essence of participatory budget is to realize the diversification of budget management subject and let the public participate in budget decision and share budget power.However,the pilot practice of participatory budget conducted by some local government in China still has many problems such as the lack of system standardization,the limit of budget subject’s qualification and ability, the limitation of participating width and depth as well as the uniqueness of participating form.Therefore the future development of China’s participatory budget should focus on improving the institutionalization of participatory budget, training the qualified participating subject,expanding the scope of public participatory budget and regulating the procedure and means of participatory budget.By doing so can we realize the goal of public budget management to the maximum extent.

套期会计方法应用条件改进研究

财会月刊 , 2011,
Abstract: 由于套期保值会计准则对套期会计方法应用的条件进行了严格的界定以及相关制度的缺失,套期会计方法在会计实务中的应用受到了极大的限制。本文以X公司为例,在分析其套期会计方法应用现状的基础上,对其套期会计方法的适用性进行了剖析,最后结合套期会计的国际改进,提出了修订我国套期保值会计准则的建议。  【关键词】套期保值套期会计会计准则  随着衍生金融市场的不断发展,套期会计方法的应用对提高企业会计信息质量具有越来越重要的意义。企业会计准则中对套期会计方法的应用规定了若干限制条件,但由于套期保值业务中套期工具和被套期项目自身公允价值或现金流量变动的复杂性,对是否满足套期会计方法应用条件的理解和判断在不同人员之间经常会出现分歧,尤其在企业会计人员和会计师事务所的注册会计师之间这一问题尤为突出。如何理解和判断是否满足套期会计方法应用条件成为我国会计实务和审计实务中亟待解决的难题,对套期会计方法应用条件的研究必将有助于解决这一现实问题。
高管股权激励与上市公司价值创造关系的实证研究

财会月刊 , 2011,
Abstract: 本文基于价值创造角度,从委托代理理论和激励理论出发,研究上市公司最高管理层股权激励与企业价值之间的关系,并选取沪深A股市场2005~2009年披露高管持股信息的上市公司财务数据为研究样本,构建了上市公司高管股权激励水平与企业价值关系的模型。 【关键词】企业价值经营活动现金流经济增加值(EVA)股权激励当前,我国许多上市公司都引入了股权激励制度作为公司高管薪酬激励计划的一部分,这是因为股权激励制度有助于完善企业的公司治理机制、合理计算和体现企业高管这一特殊人才的人力资本价值。本文选取沪深两市A股市场2005~2009年实行股权激励计划的1695家上市公司为研究样本,找出影响企业价值的关键财务变量,最终得出经营活动现金流指标与高管股权激励程度存在强线性相关关系,表明上市公司最高管理层创造的企业价值越多,其股权激励水平也就越高。创造现金流能力应作为高管业绩考核的关键指标之一。

中国城镇化对经济增长的影响及其时空分化

人口研究 , 2013,
Abstract: ?文章构建以人口及空间城镇化为解释变量,以消费、投资为控制变量的经济增长解释模型,并采用1996~2011年中国省域面板数据进行估计。结果显示:人口及空间城镇化主要通过投资传导促进经济增长,没有形成对消费的推动。从时间上看,2007年实施新型城镇化战略后,人口城镇化对经济增长的影响效应明显提升,尤其是开启对消费的传导,空间城镇化通过投资传导对经济的促进效应也明显提升。从空间上看,东部人口及空间城镇化主要通过投资传导对经济产生促进作用,而在中西部,除中部人口城镇化通过投资传导略拉动经济增长外,其余人口城镇化作用均不显著,另外,空间城镇化虽然也能通过投资传导促进经济增长,但仍不足以抵消通过消费传导产生的抑制作用。
冻融冻藏过程中κ-卡拉胶对面筋蛋白流变学特性及微观结构的影响

- , 2017, DOI: 10.13982/j.mfst.1673-9078.2017.11.005
Abstract: 利用流变仪、傅里叶变换红外光谱(FT-IR)、激光共聚显微镜(CLSM)探讨添加卡拉胶后对面筋蛋白在冻融过程中流变特性、和结构的影响。结果表明在冻融过程中,面筋蛋白的储能模量(G')、损耗模量(G'')和二级结构随冻融时间的延长其变化分为三个阶段:从冻融开始到30 d为第一个阶段,面筋蛋白的G'、G''随着时间的延长明显下降,二级结构中1629 cm-1处β折叠含量上升%,同时1656 cm-1处α螺旋含量相对下降;冻融30 d到90 d为第二个阶段,面筋蛋白的流变特性和结构变化相对不太明显;冻融90 d到120 d为第三个阶段,G'、G''进一步下降,而1613 cm-1处β折叠含量上升,对应的1656 cm-1处α螺旋含量相应下降。CLSM显示冻融0 d时卡拉胶的分布主要集中在面筋蛋白网络结构的边缘,随着冻融时间的延长卡拉胶与面筋蛋白充分混合,形成蛋白多糖络合物增强面筋蛋白的凝胶特性,而当冻融时间达90 d后,面筋蛋白网络结构进一步破坏,出现了大量不规则的孔洞。
In this paper, the effects of κ-carrageenan on the rheological properties, secondary structure and microscopic property of gluten during the frozen-thaw storage were studied by Rheometer, Fourier Transform Infrared Spectroscopy (FTIR) and Confocal Laser Scanning Microscope (CLSM). The results showed that the changes of the storage modulus (G'), loss modulus (G") and the secondary structure of the gluten were divided into three stages during the frozen-thaw storage. The first stage was form 0 d to 30 d, where the G' and G" of the gluten decreased dramatically, and the content of β-sheet (1629 cm-1) increased significantly with decreasing the content of α-helix (1656 cm-1) simultaneously. The second stage was form 30 d to 90 d, where the changes of rheometer parameters and secondary structure were not significant. During the third stage from 90 d to 120 d, the G' and G" of the gluten dropt again, while the content of β-sheet (1613 cm-1) increased significantly with the decrease of α-helixcontent simultaneously (1656 cm-1). CLSM photographs showed that the distribution of carrageenan mainly concentrated on the edge of gluten network on the frozen-thaw 0 d, and then the carrageenan fully mixed with wheat gluten during the storage, which led to enhance gel properties of gluten. However, the gluten network structure was further damaged and a large number of irregular hole emerged up to 90 d.

Abstract:
万载兴源冲铜矿地处宜丰景德镇板缘深断裂带西段黄茅地区。本文在前人研究基础上,通过对不同矿体矿石中的石英、方解石等脉石矿物进行系统的流体包裹体测温工作,来探讨矿区成矿流体来源。流体包裹体测温得出包裹体均一温度在75~440之间,主要分布于两个温度区间:110~190210~290,显示中低温的特征;盐度变化范围在1.74 wt%~22.58 wt%之间,显示中高盐度的特征。根据均一温度盐度图可以看出矿床成矿流体大致以海底喷流热液和与成岩作用有关的水为主,也有小部分岩浆热液的混合
Xingyuanchong copper deposit at Wanzai is located in the west section of Yifeng-Jingdezhen deep faults—Huangmao. On the basis of previous researches, and by carrying out temperature measurement of fluid inclusions systematically on gangue minerals, such as quartz and calcite, the authors discussed the sources of metallogenic fluids. The results show that 1) the homogenization temperatures of fluid inclusions vary in the range of 75?C~440?C, mainly in two sections: 110?C~ 190?C and 210?C~290?C, showing the feature of low medium temperatures; 2) the salinity ranges from 1.74 wt% to 22.58 wt%, suggesting medium high salinity. The homogenization temperature- salinity figure indicates the metallogeinic fluids are mainly submarine extrusive hydrothermal fluids and fluids related with diagenesis, and a small part of magmatic fluids.
