Recent Research Progress on Study of Paragonimus westermani in China  [PDF]
Dingli Xu, Jing Li, Qi Liao, Tuergong Jiang, Jiang Cai, Yuelong Lv, Jiakuan Lv, Baile Shen, Zexian Xu, Yanting Zhang, Jianfa Liu
Open Access Library Journal (OALib Journal) , 2015, DOI: 10.4236/oalib.1101511
Abstract: Recently, along with the development of biochemical and molecular immunological techniques, the diagnosis methods have been improved in which preparing natural parasite antigens, and genetically engineered recombinant antigens have been applied by using agglutination test, complement fixation methods to detect the human’s serum antibodies for parasite identification of paragonimus infections. To improve the detection rate, some scholars have used phage peptide library technology to further improve the diagnostic effect on Paragonimus westermani in humans. In this paper, we summarized recent studies on diagnosis, pathogenesis and treatment of Paragonimus flukes in China.
Deformation mechanism of compression of 2024 Al alloy in semi-solid state
Shoujing Luo,Jiakuan Sun
Chinese Science Bulletin , 1999, DOI: 10.1007/BF02886092
Abstract: The deformation mechanism of alloy in the semi-solid state has been investigated, with the compression of 2024 Al alloy in the semi-solid state as an example. Experimental results showed that the compressive deformation of 2024 Al alloy in the semi-solid state was mainly caused by the liquid flowing under the hydrostatic compressive stress, the grain boundary sliding under the shear stress and the plastic deformation of grain under the normal compressive stress. Among them, the grain boundary sliding was mainly accommodated by the nucleation and growth of cavity under the hydrostatic tensile stress.
Causes of Peripheral Blood Cytopenias in Patients with Liver Cirrhosis Portal Hypertension and Clinical Significances  [PDF]

Open Journal of Endocrine and Metabolic Diseases (OJEMD) , 2014, DOI: 10.4236/ojemd.2014.44010

Liver cirrhosis portal hypertension patients to reduce the number of blood cells are common in clinical, and often affect the prognosis. This paper discusses cirrhotic portal hypertension patients complicated by the reason of the decrease in the number of peripheral blood cells and what is the clinical significance of these reasons so as to provide theoretical support for the choice of treatment. Splenomegaly and hypersplenism caused should be the main reason for reducing the number of blood cells, but not all, other reasons are alcohol and virus inhibition of bone marrow, liver function impairment, autoimmune damage and loss of blood, etc. If it is a function of the spleen hyperfunction caused by blood cells decreases, blood should rise to normal after splenectomy, or consider other reason or there are other reasons at the same time.

Abstract: The modified generality degree distance, is defined as: \"\",?which is a modification of the generality degree distance. In this paper, we give some computing formulas of the modified generality degree distance of some graph operations, such as, composition, join, etc.
Study on the Dynamic Mechanism of College Student Organization  [PDF]
Yinghan Lv
Open Journal of Social Sciences (JSS) , 2018, DOI: 10.4236/jss.2018.612014
Abstract: College student organization plays an important role in the management of college. A college in Chengdu has become a hot topic on weibo because of a screenshot of a dialogue with strong bureaucratic color recently, which have attracted wide attention of the society. The management problem of college student organization keeps showing up. How to keep the initiative and advancement of college student organization has become an important subject in college research. Based on the analysis of the current situation of college student organization, this paper explores the dynamic mechanism of college student organization, and puts forward feasible suggestions on the management of college student organization.
Effects of Root Extracts from Panax ginseng C. A. Meyer (Araliaceae) of Different Ages on K562 Cells  [PDF]

It is well accepted in China that elder ginsengs have more bioactivity and value than younger ones. However, there is little research about the comparison of beneficial effects of ginsengs with different ages. In this study, ginseng root extracts (GRE) were extracted from ginsengs of 5, 8, 12, 14, and 16 years old, respectively, using 55% ethanol and their effects on human leukemic K562 cells within 48 hours were tested by using Cell Counting Kit-8. The results show that there are significant increases in the cell viability of all the GRE groups compared with Control group within 32 hours. Furthermore, the growth curves of GRE groups were obviously distinct from each other. The cell viability of 5-year-old and 8-year-old GRE groups kept a rapid increase while that of 16-year-old GRE group showed a strong fluctuation within 28 hours. Our results demonstrate that root extracts from ginsengs of different ages contain different bioactivity constituents and have different effects on cell.

A Study of Independent Director’s Reputation Incentive Mechanism Based on the Principal-Agent Theory  [PDF]
Xiaoning LV, Yang LIU
iBusiness (IB) , 2009, DOI: 10.4236/ib.2009.11006
Abstract: This paper applies principal-agent theory to research into the incentive compatibility problems of the independent directors (IDs). The traditional fixed-pay system could preserve the independence of IDs, however, lacking of in-centives, the performance-related incentive mechanisms have great impact on IDs' independence which is the core of the system. This paper considers reputation incentive mechanism (RIM) as an effective way to solve this dilemma. The results, after our study, show that appropriate RIM can maintain IDs' independence as well as their incentive compati-bility. Furthermore, taking the market-signal theory as reference, this paper sets up a model to introduce another func-tion of RIM, which can help the company to identify the different roles of IDs.
EST Translation Guided by Reception Theory  [PDF]
Liangqiu Lv, Puyu Ning
Open Journal of Modern Linguistics (OJML) , 2013, DOI: 10.4236/ojml.2013.32015
Abstract: In the thesis, Reception Theory is introduced to the studies of EST translation to explore the mutual influence and restriction between the author, the translator and readers, as well as the respective reception problems, on the basis of which, the characteristics, principles and strategies of translation are analyzed.

The Relationship between Social Skills and Sports Activities among Chinese College Students  [PDF]
Lu Lv, Kazushi Takami
Psychology (PSYCH) , 2015, DOI: 10.4236/psych.2015.64036
Abstract: The purpose of this study was to understand the current state of social skills among Chinese student, especially focused on the students who participated in sports clubs and took physical exercise regularly, and subsequently conducted a new multi-index model further to explore the relationship between social skills and sports activities. 3000 college students were investigated by two scales named revised Chinese university-student social skills inventor (RChUSSI) and the Chinese college students’ version of Buss-Perry aggression questionnaire (CC-BPAQ), and resulted in 2543 (84.7%) samples return. By the help of analysis of variance and multivariate analysis of covariance, a multi-index model was conducted and examined. This study reported that the period of primary and secondary school might be the most productive years of human achieving and training social skills. Taking sports activities facilitated learning and improving social skills. Thus, primary and secondary school students are encouraged to have sports activities, which are good for their physical and mental health.
