Journal of Geriatric Cardiology 2016年第11期13卷 894-898页

作者： ji-li yun Xiao-Ying li Medical School of Chinese PLA General Hospital Beijing China Department of Geriatric Cardiology Chinese PLA General Hospital Beijing China

Objectives To investigate the prevalence and characteristics of pulmonary embolism （PE） at autopsy in a Chinese general hospital over a period of 10 years, and to evaluate the antemortem achievement of the prophylaxis, diagnosis, and treatment of PE. Methods All medical records of deaths from the West Branch of the Chinese People＇s liberation Army （PLA） General Hospital were retrospectively re- viewed, for the period of January 1, 2006 to December 31, 2015. Cases in which autopsies had been performed were identified and further analyzed. The numbers and detailed characteristics of patients who had PEs were noted. Prophylactic measures, along with diagnosis and treatment of PE, were recorded, if performed. Results During the 10-year period, 1057 patients died in the study hospital and 278 necrop- sies were performed （autopsy rate： 26.3%）. Nine patients were found to have PE （3.2%）, and in seven of these patients （2.5%）, the PE was considered to be fatal. Embolisms were found in the trunk and bilateral main branches of the pulmonary artery tree in all seven of the fatal PE cases. Right intracardiac thrombosis was detected in five of the nine PE patients （55.6%）. All patients with PE had been hospitalized in medical departments, and only one had undergone surgery during hospitalization. Antemortem prophylaxis was performed in two of the nine PE cases （22.2%）. None of the 9 patients had received a clinical diagnosis of PE before death. Conclusions The incidence of and death rate associated with PE may vary among different races and regions. Continuous monitoring of PE by means of necropsy in certain representative medical institutions is necessary.

Leakage and Stiffness Characteristics of Bionic Cluster Spiral Groove Dry Gas Seal

引用

Chinese Journal of Mechanical Engineering 2018年第2期31卷 148-158页

Spiral groove dry gas seal(S?DGS), the most widely used DGS in the world, encounters the problem of high leakage rate and inferior film stability when used in high?speed machinery equipment, which could not be well solved by optimization of geometrical parameters and molded line of spiral groove. A new type of bionic cluster spiral groove DGS(CS?DGS) is proved to have superior film stability than S?DGS at the condition of high?speed and low?pressure numerically. A bionic CS?DGS is experimentally investigated and compared with common S?DGS in order to provide evidence for theoretical study. The film thickness and leakage rate of both bionic spiral groove and common spiral groove DGS are measured and compared with each other and with theoretical values under different closing force at the condition of static pressure, high?speed and low?pressure, and the film stiffness and stiffness?leakage ratio of these two face seals are derived by the relationship between closing force and film thickness at the steady state. Experimental results agree well with the theory that the leakage and stiffness of bionic CS?DGS are superior to that of common S?DGS under the condition of high?speed and low?pressure, with the decreasing amplitude of 20% to 40% and the growth amplitude of 20%, respectively. The opening performance and stiffness characteristics of bionic CS?DGS are inferior to that of common S?DGS when rotation speed equals to 0 r/min. The proposed research provides a new method to measure the axis film stiffness of DGS, and validates the superior performance of bionic CS?DGS at the condition of high?speed and low?pressure experimentally.

Mapping Quantitative Trait Loci for Post-Anthesis Dry Matter Accumulation in Wheat

Journal of Integrative Plant Biology 2006年第8期48卷 938-944页

Post-anthesis photoassimilation is very important for wheat （Triticum aestivum L.） grain filling. The aim of the present study was to map quantitative trait loci （QTL） for post-anthesis dry matter accumulation （DMA）. A set of 120 doubled haploid （DH） lines, derived from winter wheat varieties Hanxuan 10 and Lumai 14, was grown under field conditions in two consecutive growing seasons during 2002-2004 in Beijing. Post-anthesis DMA per culm and related traits, including flag leaf greenness （FLG） and flag leaf weight （FLW; dry weight per flag leaf） at flowering, and grain weight per ear （GWE） were investigated. All traits segregated continuously in the DH population in both trials. The DMA was significantly and positively correlated with GWE, with the correlation coefficients being 0.79 and 0.66 in the 2002-2003 and 2003-2004 growing seasons （both P〈0.01）, suggesting the importance of DMA in grain filling. Further correlation analysis showed that FLW was more closely correlated with DMA and GWE than FLG in both growing seasons, indicating that FLW was more important than FLG in influencing DMA and GWE. In total, 30 QTLs for these four traits were mapped and distributed on 10 chromosomes. Phenotypic variations explained by an individual QTL were in the range 5.8%-21.3%, 5.9%-17.2%, 5.1%-18.1%, and 5.6%-16.2% for FLG, FLW, DMA, and GWE, respectively. Eight QTLs for DMA were detected, of which four （on chromosome arms 2AS, 4BL, 5AS, and 7AS） were linked with QTLs for GWE; two （on chromosome arms 5BL and 7BL） coincided with QTLs for FLW. These results may provide useful information for developing marker-assisted selection for the improvement of DMA.

Implicit Trust Based Context-Aware Matrix Factorization for Collaborative Filtering

引用

Journal of Donghua University(English Edition) 2016年第6期33卷 914-919页

作者： li ji-yun SUN Cai-qi School of Computer Science and Technology Donghua University Shanghai 201620 China

Matrix factorization （MF） has been proved to be a very effective technique for collaborative filtering （ CF）, and hence has been widely adopted in today＇s recommender systems, Yet due to its lack of consideration of the users＇ and items＇ local structures, the recommendation accuracy is not fully satisfied. By taking the trusts among users＇ and between items＇ effect on rating information into consideration, trust-aware recommendation systems （TARS） made a relatively good performance. In this paper, a method of incorporating trust into MF was proposed by building user-based and item-based implicit trust network under different contexts and implementing two implicit trust-based context-aware MF （]TMF） models. Experimental results proved the effectiveness of the methods.

转移农业剩余劳动力,消除二元经济结构,是实现新农村建设目标的重要途径。以云南劳动力转移为例,分析了农村劳动力转移与城镇化发展的关系,城市化水平滞后、现行的户籍制度、劳动力市场发育滞缓和农村劳动力素质低等是两者不能协调发展的主要原因。改革户籍与土地制度,赋予农民工平等的劳动力保障权利、坚持多元城镇化转移农村富余劳动力原则、大力发展二、三产业,为农村剩余劳动力转移提供就业机会等是劳动力转移与城镇化协调发展之良策。

结直肠癌(CRC)是一种常见的、发生及发展过程复杂的消化系统癌症,其复杂、多级的发生发展过程会影响机体免疫功能,引起免疫变化。外周血单个核细胞(PBMC)是机体免疫系统的重要组成部分,且便于获取,是研究机体免疫功能的理想材料。本研究采用最新的数据非依赖采集(data independent acquision,DIA)质谱新方法结合Skyline软件对结直肠癌患者与良性肠病患者的PBMC蛋白进行定量比较,寻找差异表达蛋白,并对差异蛋白进行Reactome通路及GO分析。结果表明,共找到113个差异表达蛋白,其中,上调蛋白23个,下调蛋白90个,它们参与巨噬细胞、T细胞、树突细胞等多种外周免疫细胞的免疫活动。在这些差异蛋白中,上调蛋白Galectin-1及下调蛋白Dok-2和AHNAK1等蛋白与机体的免疫功能息息相关,有望成为外周血单个核细胞中的结直肠癌免疫标志物。
