把握宏观数据与微观感受之间的关系是近年来被普遍关注的问题,但宏观数据与微观感受不一致的原因、影响和背后的政策涵义在研究中尚存在诸多的争议。其中,生活成本变化、就业收入走势和价格总水平的波动是与生产、居民生活直接相关的重要宏观变量,也是最容易产生宏观数据与微观感受相背离的领域。本文在现有研究的基础上,结合国内外出现的新形势、新特点,分析造成宏观数据与微观感受不一致的重要原因。同时,在分析其未来走势的基础上,提出相应的政策建议。

光生电荷的分离和转移被认为是影响BiVO_(4)基光阳极光电性能的核心因素之一.本文设计了在BiVO_(4)光阳极与析氧助催化剂之间插入空穴提取层的方法.Cu_(2)O作为空穴提取层引入到助催化剂层(FeOOH/NiOOH)和BiVO_(4)之间,可以有效优化空穴的迁移路径,延长光生空穴的寿命,从而提高电极的光电化学性能.与BiVO_(4)相比,调整后的BiVO_(4)/Cu_(2)O/FeOOH/NiOOH光阳极的电荷分离效率从70.6%提高到了92.0%.此外,该光阳极在1.23 VRHE(AM 1.5G照明下)下,还显示出了3.85 mA cm^(-2)的高光电流密度,是BiVO_(4)的2.77倍.我们的研究结果表明,电沉积Cu_(2)O空穴提取层是一种简单且可扩展的方法,能够有效提高BiVO_(4)的光电活性,可用于太阳能驱动水分解领域.

胰腺导管腺癌(PDAC)是胰腺癌中一种常见的恶性肿瘤类型,疾病进展快、恶性程度高、预后差、对放化疗不敏感。PDAC的恶化、远处转移、治疗抵抗不仅取决于PDAC细胞,肿瘤微环境在疾病进展与演变的过程中也发挥着不可或缺的作用。胰腺星状细胞(PSCs)是建设肿瘤微环境重要的参与者,为癌细胞的“成长”构建一个“舒适”的微环境。本文通过总结PSCs在肿瘤微环境的发挥的作用以及对PDAC的影响,希望可以从肿瘤微环境方面改善治疗方案,提高患者的生存率。

Based on the multi-regional input-output framework, this paper analyzed the labor and energy transfer embodied in interregional trade in China. Meanwhile, through estimating the energy intensity per unit of labor embodied in final products in each region, this study examines whether the empirical results are consistent with the theoretical hypothesis and provides relevant explanations and industrial development suggestions. Results show that east coastal region and central region are the two main participants in interregional trade. As for the labor embodied in trade, east coastal region is the largest exporter of embodied labor, though it has the highest wage among eight regions; in contrast, north coastal and southwestern region, with relatively low wage, are the two largest importer of embodied labor. As for the energy embodied in trade, northwestern region is the largest exporter of embodied energy. Further analysis indicates that the energy intensity per unit of labor in region with relatively low GRP(such as northwestern region) is the highest,whereas those in Beijing-Tianjin Region and south coastal region(with relatively high GRP) are the lowest. By analyzing the Revealed Comparative Advantage in each region, the paper finds that the main reason for this inconsistency lies in the industrial structure in northwestern and north coastal region, which are highly dependent in primary industries. Improving the infrastructure and upgrading industrial structure are important steps for these regions to transform the extensive growth mode.

A duplex treatment of plasma Zr-alloying and plasma nitriding was used to improve the tribological properties of Ti-6Al-4V. The microstructure of the Zr-N composite（alloyed） layer formed on Ti-6Al-4V and its hardness, friction and wear properties were investigated by using OM, SEM, GDOES, EDS, microhardness tester as well as ball-on-disk tribometer. The results of microstructural analysis show that the alloyed layer is compact and uniform and is mainly composed of ZrN, TiN_（0.3） and AlN. A very tiny adhesive and slight oxidation wear is the primary wear mechanism for the modified Ti-6Al-4V. The tribological property is improved significantly after the duplex treatment. The good combination of antifriction and wear resistance for modified Ti-6Al-4V is mainly attributed to the higher surface hardness of metal nitrides formed on the surface and enhanced supporting of the Zr-diffusing layer.

BACKGROUND:Caroli’s disease, a rare congenital hepatic disease, has a poor prognosis, especially in patients with diffuse dilatation of the bile ducts. But liver transplantation has been a curative option. The aim of this study was to investigate the feasibility and rationality of orthotopic liver transplantation as an indication for patients with diffuse Caroli’s disease. METHODS:The data from 3 patients with diffuse Caroli’s disease who had undergone orthotopic liver transplantation in our unit were analyzed retrospectively. RESULTS:On postoperative day 7, patient 1 had acute rejection which was relieved after pulse treatment with methyprednisolone. He was discharged from hospital on postoperative day 27 and has been in good health for 82 months. Patient 2 had no acute rejection or severe complications, but died of chronic graft dysfunction 34 months postoperatively. Patient 3 had acute rejection on postoperative days 10 and 35, complicated with pulmonary infection, pleural effusion and opportunistic infection. After successful treatment, she resumed work and has been followed up for 47 months. Her condition is good. CONCLUSION:Liver transplantation can offer an effective therapy for patients with diffuse Caroli’s disease, and can provide satisfactory long-term results.
