Synergistic Effects of Targeting Survivin and CDK1 on Nasopharyngeal Carcinoma in Vitro and in Vivo  [PDF]
Hongtao Zhou, Xinping Chen, Shuping Chen, Junhong Cai, Jiye Zhang, Shengmiao Fu
Journal of Cancer Therapy (JCT) , 2019, DOI: 10.4236/jct.2019.104024
Abstract: Background: To explore the impact of pU6-based tandem survivin and CDK1-specific short hairpin RNA on the biological behaviors of CNE-2 nasopharyngeal carcinoma cells in vitro and in vivo. Patients and Methods: The vectors of pU6-survivinshRNA, pU6-CDK1shRNA and
pU6-survivinshRNA-CDK1shRNA were constructed and transfected into CNE-2 cells with Lipofectamine TM 2000, respectively. The mRNAs and proteins of CDK1 and survivin were determined by RT-PCR and Western blotting, accordingly. MTT assay was employed to evaluate the proliferation of CNE-2 cells, and flow cytometry was performed to determine the apoptosis of CNE-2 cells. The effects of interfering survivin and CDK1 on tumorigenesis were evaluated by tumor xenografts experiments. Results: Effective plasmids were successfully constructed knocking down survivin and/or CDK1. The proliferation inhibition of CNE-2 cells by pU6-survivinshRNA-CDK1
Agency Cost under the Restriction of Free Cash Flow  [PDF]
Junhong Chu
Journal of Service Science and Management (JSSM) , 2011, DOI: 10.4236/jssm.2011.41011
Abstract: Agency cost theory is an important branch of capital structural theory. Free cash flow has significant impact on agency cost. The combination of research on these two fields would help to build and extend the theoretical system. Based on agency cost theory, the present study firstly categorized the characteristics of free cash flow as well as the statistical methodologies. Furthermore, the existence of investing free cash flow in agency cost was proved by a model. Then free cash flow was introduced into agency cost theory as restriction, the analysis shows that it will change agency cost, in turn, will have an impact on the relationship between agency cost and capital structure, finally, will influence the optimal capital structure point to maintain the equilibrium. Concretely, with the increasing free cash flow, correspondingly, debt proportion will decrease.

Abstract: In this paper, we study geodesic contact CR-lightlike submanifolds and geodesic screen CR-lightlike (SCR) submanifolds of indefinite Sasakian manifolds. Some necessary and sufficient conditions for totally geodesic, mixed geodesic, -geodesic and -geodesic contact CR-lightlike submanifolds and SCR submanifolds are obtained.
A Study on College English Ecological Teaching Strategies in China  [PDF]
Junhong Tang, Wei Zhang
Open Journal of Modern Linguistics (OJML) , 2013, DOI: 10.4236/ojml.2013.33031

The aim of this study was to create ecological college English teaching strategies in non-English speaking countries in view of the increasing importance and popularity of English. The study shows most college students hope they are able to learn English well and they will be very happy if college English teachers can adopt some efficient and suitable teaching strategies. In this paper, the author puts forward college English teaching is a kind of micro-ecosystem in the light of ecology which has got such ecological characteristics as adaptability, openness and sustainability. In order to create suitable ecological college English teaching environments, the college English teaching are supposed to insist on 5C principles, that is, cooperation, competition, consideration, creativeness and continuity which are on the basis of such ecological principles as “Symbiotic Effect”, “Niche”, “Laws Limiting Factor”, “Law of Tolerance”, “the Most Appropriate Principle”, “Flowerpots Effect”. The efficiency and practicality of college English teaching in non-English speaking countries are able to be obtained by using ecological college English teaching strategies discussed in the paper.

The study also conveys most students have realized the importance of ecological consciousness in solving the current ecological crisis. They also would like to gain ecological consciousness and accept the three ways discussed in the part of discussion of cultivating their ecological consciousness. Because college students are the precious source of the world and thus colleges have the special mission of guiding the social trend, developing the social culture and making contributions to spiritual construction, it is absolutely urgent and necessary for colleges to make any effort to cultivate college students’ ecological consciousness.

Dorian Gray’s Spiritual Ecological Crisis and the Inspiration to Modern People  [PDF]
Junhong Tang, Wei Zhang
Advances in Literary Study (ALS) , 2013, DOI: 10.4236/als.2013.12002
Abstract: As an individual of spiritual existence, Dorian Gray, in The Picture of Dorian Gray, lacked the ability to love his lovers and friends, lost the normal aesthetic ability, failed to control his gradually increasing evil desires, so his body and soul began to go far away step by step. The imbalance and instability of his spiri-tual factors like love ethic, moral ethic, aesthetic ethic and life ethic led to the completely collapse of Dorian’s spiritual ecological system, even to his suicide. Dorian’s spiritual ecological crisis inspires the modern people a lot. It provides people with a full view of their own life style, stimulates people to pay more attention to their own spiritual ecological system, and spurs modern people on to adjust their spiritual factors in the right orbit of balance and stability. The government and the public media are supposed to play their part in keeping citizens well-informed of the potential benefit of the normal spiritual eco-logical system. Only does a person’s spiritual ecological system runs in order, he can live normally and make contributions to others, to the society.

The Opposition and Integration between Civilization and Nature―Analysis of Wuthering Heights from the Perspective of Eco-Criticism  [PDF]
Junhong Tang, Yan Liu
Advances in Literary Study (ALS) , 2014, DOI: 10.4236/als.2014.24022
Abstract: Eco-criticism offers a new perspective for us to study Wuthering Heights. In Wuthering Heights, the place of Wuthering Heights and the residents are the representatives of nature, while the place of Thrushcross Grange and the residents are the spokesmen of civilization. The history of the changing relationship between the human beings and the nature is reflected in the relationships of the main characters in Wuthering Heights. Long ago the human beings lived in awe of the nature and admired it and then they exploited the nature excessively. At last they return to respect the nature and form a harmonious relationship between the human beings and the nature under the guidance of the eco-ethic. With the deterioration of the environment, the relationship between the human beings and the nature reflected in Wuthering Heights drives the modern people to think deeply.
