基于组合赋权和集对分析的施工项目绿色集成评价

随着建筑业对绿色环保和信息化水平的要求越来越高,传统的施工项目评价难以满足建筑业可持续发展的需要。文章利用扎根理论在传统评价的基础上,增加了绿色施工和信息化评价,构建8个维度的施工项目绿色评价指标体系;通过问卷调查和改进的群组G1赋权法对指标权重进行合理分配;最后结合集对分析计算指标等级联系度,建立面向施工项目的绿色评价模型,并通过工程实例验证了模型的有效性。     

The changing patterns of China’s international standardization in ICT under techno-nationalism: A reflection through 5G standardization

The U.S.-China dispute surrounding 5G motivates further examination on China’s approach to international standardization. While China’s challenges with various standard initiatives to the global standards regime peaked in the 5G dispute have attracted public interests, scholarly approach to the dispute is still limited. We place the dispute in the context of China’s long-standing attempts for international standardization in ICT sectors. With enhanced economic power, China has pursued for pushing indigenous technologies into international standards, which has been a core part of its national science and technology (S&T) policy. This paper examines China’s international standard initiatives from the perspective of techno-nationalism. Our literature review identifies three pillars of techno-nationalism: state empowerment, growth orientation, and global connection. Then we investigate three cases of WAPI, TD-SCDMA and 5G and discuss how the patterns of developing international standards have varied in the framework of techno-nationalism. Over time, China’s international standard initiatives based on techno-nationalism have strengthened global connection and growth orientation, with increasing proximity to techno-nationalism of the Western style. In particular, China’s aspiration for growth orientation was much enhanced with the 5G standard initiative, compared to WAPI or TD-SCDMA, as it aims to be the first mover in the 5G race. Overall, our study suggests that China’s national S&T policy has been moving from the ‘catch-up’ to the ‘first-mover’ strategy, but the transformation continues to take place in the framework of techno-nationalism.

低负荷加压训练改善自发性高血压大鼠的血压效果及机制研究

目的:探究低负荷加压训练对自发性高血压大鼠的降压效果及其作用机制。方法:选取4周龄雄性自发性高血压大鼠,随机分为对照组(高血压安静组)、低负荷训练组、低负荷加压训练组和高负荷训练组。低负荷训练组进行35%~55%1RM递进式低负荷爬梯训练,低负荷加压训练组进行30%~40%血流受限结合35%~55%1RM递进式低负荷爬梯训练,高负荷训练组进行55%~75%1RM递进式高负荷爬梯训练,训练后测定血压、血液中内皮素-1、血管内皮生长因子、一氧化氮合成酶的表达和心肌组织中内皮型一氧化氮合成酶的表达。结果:1)与对照组、高负荷训练组相比,低负荷加压训练组收缩压、舒张压显著下降(P<0.05);与低负荷训练组相比,低负荷加压训练组舒张压显著下降(P<0.05)。2)与对照组相比,低负荷加压训练组血液中内皮素-1表达显著下调(P<0.05),血管内皮生长因子和一氧化氮合成酶表达显著上调(P<0.05);3)与对照组相比,低负荷加压训练组心肌中内皮型一氧化氮合成酶表达显著上调(P<0.05);4)在低负荷加压训练组中,收缩压与内皮素-1呈正相关,相关性分析具有统计学意义(P<0.05);收缩压与一氧化氮合成酶、血管内皮生长因子、内皮型一氧化氮合成酶均呈负相关,相关性分析具有统计学意义(P<0.05)。结论:1)低负荷加压训练降压效果优于高负荷训练;2)低负荷加压训练能够通过下调血液中内皮素-1的表达,上调血液中血管内皮生长因子和一氧化氮合成酶的表达,同时上调心肌中内皮型一氧化氮合成酶表达,改善内皮细胞功能,达到降压的效果。     

Utility of P-SEP,sTREM-1 and suPAR as Novel Sepsis Biomarkers in SARS-CoV-2 Infection

The coronavirus disease 2019 is a highly contagious viral infection caused by SARS-CoV-2 virus, member of coronaviridae family. It causes life threatening complications due to complexity and rapid onset course of the disease. Early identification of high-risk patients who require close monitoring and aggressive treatment remains challengeable till date. Novel biomarkers which help to identify high risk patients at the early stage is high priority. Objective of this review to find utility of P-SEP, sTREM-1 and suPAR for diagnosis, risk stratification and prognosis of SARS-CoV-2 infected cases. Soluble receptors like, P-SEP, sTREM-1 and suPAR have been involved in immune regulation in SARS-CoV-2 infection and elevate more in severe cases. A comprehensive research of databases like PubMed, EMBASE, CNKI and Web of Science was performed for relevant studies. A total of nine out of fifteen research literature in initial screening were included for this review. Interestingly all studies have reported high levels of P-SEP, sTREM-1 and suPAR in SARS-CoV-2 infected cases and the biomarkers positively correlated with severity of infection. This implies that P-SEP, sTREM-1 and suPAR can be implemented as surrogate marker in blood profile for early diagnosis, risk stratification and prognosis in SARS-CoV-2 for better management in Indian population at the current situation.
