The reproductive health indices and sex hormone levels in middle-aged and elderly Chinese men

Objective: The aim of this study was to analyze the age-related recession trajectory of reproductive health indices in middle-aged and elderly Chinese men.

Methods: A population-based cross-sectional study was conducted in Jiashan County, Zhejiang in 2012. Healthy men between 40 and 80 years of age were considered eligible for the study. Physical examination and the sex hormones were measured. The subjects were assessed based on the 5-item version of the International Index of Erectile Function (IIEF-5) for Erectile Dysfunction (ED), and Aging Males’ Symptoms (AMS) scale for Symptomatic Late-Onset Hypogonadism (SLOH).

Results: TG showed a decrease at age 60 years. Testis volume and TT did not show significant difference among the four age groups; cFT began to decrease at age 50 years and Bio-T decreased faster at age 50 years. SHBG and LH increased faster at age 50 and 70 years, respectively. IIEF5 score decrease faster at age 60 years. AMS scores increased faster at age 70 years. With the increase in age, the symptoms of ED and SLOH became severer.

Conclusion: Different indices on reproductive health of men showed turning points at different ages. At first, androgenic sex hormones decreased faster, and then erectile dysfunction got severer, and the last overall male syndromes declined.     

China and global internet governance: toward an alternative analytical framework

Drawing on historical methods, this study assesses the conventional “cyber-sovereignty” framework, which has been used to capture and interpret China’s stance toward global Internet governance. This framework focuses on political control and tends to reduce China’s policies to the attempts by an authoritarian state to elevate governments and intergovernmental organizations to be the only legitimate governors of global cyberspace. As it traces the evolution of China’s relationship with the global Internet in the past three decades, the study demonstrates that China’s stance is more complex than the prevalent framework allows and that it is both built upon and different from the US-centric, market-oriented Internet governance scheme. This study recognizes the inadequacy of the conventional framework and invokes a theory of critical political economy of communication, thereby offering an alternative model to explicate the complex power dynamics behind China’s changing strategies. The alternative model advanced in this study is based on the understanding of China’s evolving approach as the product of multifaceted interactions among a group of power-holders that include both state agencies and business units on the transnational level.

马克思主义与当代中国经济学

传统社会主义经济学的弊端已被人们充分认识和批判。但是,我们在对传统社会主义经济学进行清算的时候,理应给予马克思主义以应有的评价。实践在发展,马克思主义也在不断发展。马克思主义对当代中国经济学的走向依然在发挥着重大影响,这个影响是如此真实,以至于在当代中国经济学所关注的所有重大问题中,无论人们承认与否,马克思主义的“幽灵”都无处不在。实践证明,中国经济学的发展和构建必须以马克思主义为基础。
