The aim of this study was to investigate the relationship of Cys23Ser 5-HT2c receptor gene polymorphism and the duration of IELT in men with LPE. Therefore, a prospective study was conducted in 64 Dutch Caucasian men with LPE. Baseline IELT during coitus was assessed by stopwatch over a 1-month period. All men were genotyped for Cys23Ser 5-HT2c receptor gene polymorphism. Allele frequencies and genotypes of Cys and Ser variants of 5-HT2c receptor gene polymorphism were determined. Association between Cys/Cys and Ser/Ser genotypes and the natural logarithm of the IELT in men with LPE were.investigated. As a result, the geometric mean, median and natural mean IELT were 25.2, 27.0, 33.9s, respectively. Of all men, 20.0%, 10.8%, 23.1% and 41.5% ejaculated within 10, 10-20, 20-30 and 30-60s after vaginal penetration. Of the 64 men, the Cys/Cys and Ser/Ser genotype frequency for the Cys23Ser polymorphism of the 5-HT2c receptor gene was 81% and 19%, respectively. The geometric mean IELT of the wildtypes （Cys/Cys） is significantly lower （22.6s; 95% CI 18.3-27.8s） than in male homozygous mutants （Ser/Ser） （40.4s; 95% CI 20.3-80.4s） （P = 0.03）. It is concluded that Cys23Ser 5-HT2c receptor gene polymorphism is associated with the IELT in men with LPE. Men with Cys/Cys genotype have shorter IELTs than men with Ser/Ser genotypes.展开更多

Aging education is an important part of lifelong education;more importantly, it is an important manifestation of education to deal with the aging society. The interest education of retired college teachers is an important component of the aging education and lifelong education;laying a solid foundation for the interest education of retired college teachers would make great contributions to China's aging education. Helping the retired college teachers to realize second advancement and promotion of their enterprises, as well as realizing self-values via the guiding method of interest education is an essential way under the scientific outlook on development. The realization of the interest education of retired college teachers lies in three steps;i.e. intensifying college teachers' acknowledgement of the interest education, building and perfecting the interest education institutions for the college teachers, as well as conducting the interest education of the retired college teachers.展开更多

Methods： An online questionnaire, which explored the motivation and preferences of the pharmacists to lifelong learning, was sent to all members of the Royal Dutch Pharmaceutical Society （4321） in the Netherlands. The data were analysed using a non-hierarchical clustering technique. Key findings： Two clusters of pharmacists were discovered. Cluster A pharmacists （n = 474） were more motivated by credit points （63.5% vs. 47.2%）, personal interest （84.1% vs. 56.3%）, updating knowledge （73.8% vs. 56.8%） and topicality of CE courses （47.7% vs. 26.1%）. Cluster B pharmacists （n = 199） were predominantly motivated by the aspect ＂duty as a care-giver＂ （97.0% vs. 0 % in cluster A）. Pharmacists who belonged to cluster A tended to be women （60.5%）, often worked part-time （29.3%） and mostly preferred lectures （71.1%）. Cluster B pharmacists consisted of statistically significantly more male pharmacists （52.8%, p = 0.001）, worked more full time （77.4%, p = 0.009） and mostly preferred blended learning （62.3%, p = 0.047）. Conclusions： These results suggest the use of different education formats for different kinds of pharmacists to participate in CE activities.展开更多

The consciousness of ...In the context of modern education, lifelong physical education consciousness is integrated into physical education teaching process, which plays an important role in the development of students. The consciousness of lifelong physical education can not only strengthen the theoretical basis of physical education of secondary vocational students, but also improve their comprehensive quality and anti-frustration ability, and finally guide students to have the thinking and cognition of lifelong physical education. Students in this stage of secondary vocational education are in the period of ideological establishment and rehabilitation, with strong competitiveness and self-esteem, and easy to accept new ideas, establish correct values. Therefore, secondary vocational physical education teachers need to study innovative methods of education together with schools, give guidance and guidance to students, help students form a good habit of loving physical exercise, and then achieve the goal of all-round development.展开更多

In recent years, the Ministry of Education has been calling for the all-round development of morality, intelligence, physique, beauty and labor, encouraging students to take more sports and build up their physique. The effect is not obvious enough. Especially in high school, schools generally pay attention to intellectual education, pay close attention to cultural courses, and pursue the promotion rate. Once upon a time, physical education, as a subject that was not valued highly, was often occupied by other subjects on the grounds that "the physical education teacher was ill" and "the physical education teacher asked for leave", while the students were helpless and unwilling to do so. When the students enter the university campus after the college entrance examination, the students' physique is relatively weak. Besides, due to the influence of traditional concepts, they do not attach importance to physical education class. As a result, the courses fail to keep up with the times and the phenomenon of failing the physical examination is common. As the last important stage of school physical education, university enables college students to enjoy happiness, strengthen their physique, improve their personality, exercise their will and establish lifelong sports awareness through various practical forms. Therefore, the purpose of this paper is to elaborate the significance of cultivating college students' lifelong sports in higher vocational colleges, and point out that college students' interest and habits in physical exercise should be cultivated and stimulated through various channels, so as to learn and master several sports skills and become lifelong hobbies, which will benefit them all their lives and form lifelong sports awareness.展开更多
