Despite the psychological training is relevant to, and associated with physical exercise, but its nature determines its specificity. On the psychological point of view, due to the reinforcement of external stimuli, which led to strong psychological pressure, these are manifested through the behaviors of the players when they are compete with others, such as fear, excessive psychological tension, incorrect competition motivation, ambiguous purpose, lack of confidence, even there are phenomenon like isolated characteristics and irritation, etc. Thus, the regulation and control of mental activity, the overcome of the psychological barriers, and the implementation of the psychology training have become a big question which teachers and coaches must pay attention to and need to be solved.展开更多

Negative Transfer of Culture will have cultural misunderstandings and conflicts between nations and hinder the smooth progress of cross-cultural communication. In order to avoid unnecessary misunderstanding, strengthen the friendship between different countries, we should understand, learn and overcome cultural negative transfer. This will combine theoretical knowledge and examples to explain the culture, language and culture negative relationship between migration and elaborate cultural negative transfer of two levels: Negative Transfer negative transfer surface culture and deep culture(including values migration and ethnic psychological aspects), and its negative impact on the English cross-cultural communication. In addition, this paper will propose some strategies and corresponding to the principle of helping people overcome the negative transfer in crosscultural communication, enhance cross-cultural communication ability, up from psychological acceptance, adaptation, and tolerance of different cultures.展开更多

文摘Drug resistance is mainly responsible for cancer recurrence and poor prognosis.Epigenetic regulation is a heritable change in gene expressions independent of nucleotide sequence changes.As the common epigenetic regulation mechanisms,DNA methylation,histone modification,and non-coding RNA regulation have been well studied.Increasing evidence has shown that aberrant epigenetic regulations contribute to tumor resistance.Therefore,targeting epigenetic regulators represents an effective strategy to reverse drug resistance.In this review,we mainly summarize the roles of epigenetic regulation in tumor resistance.In addition,as the essential factors for epigenetic modifications,histone demethylases mediate the histone or genomic DNA modifications.Herein,we comprehensively describe the functions of the histone demethylase family including the lysine-specific demethylase family,the Jumonji C-domain-containing demethylase family,and the histone arginine demethylase family,and fully discuss their regulatory mechanisms related to cancer drug resistance.In addition,therapeutic strategies,including small-molecule inhibitors and small interfering RNA targeting histone demethylases to overcome drug resistance,are also described.
