看红色文化如何与动漫经济相结合——动画电影《西柏坡》简评

时下红色文化热,唱红歌活动大江南北如火如荼。红色电影《西柏坡》将红色文化教育、红色旅游经济与动漫传播相结合,是一次用动画形式弘扬红色文化的大胆尝试。     

中国特色社会主义文化的哲学思考

尽管近年来我国学术界对中国特色社会主义文化进行了深入研究，取得了可喜成果，但是，对于什么是中国特色社会主义文化这个首要问题还是没有完全搞清楚并取得共识。将问题放在一定的历史环境中，具体地历史地认识和解决问题，是马克思主义哲学的基本道理。中国特色社会主义文化是一项伟大的历史性事业，有其具体的历史内涵和时空限度，对之进行时空限度的说明是我们把握其科学内涵、基本性质以及划分其发展阶段、确定其历史地位的基本前提。

文化旅游的产业属性及其发展战略——以成都市为例

分析了文化旅游和旅游的含义，认为文化旅游与旅游的根本区别在于是否以创意为前提，把文化旅游定义为创意产业，就为发展文化旅游找到了方向。并据此分析了成都的旅游资源，指出当前成都文化旅游的发展中存在混淆旅游和文化旅游以及把某一文化样式当作旅游片面发展的误区，提出将成都定位成富有多元文化魅力的度假休闲基地的发展思路。

Simulated microgravity inhibits the proliferation of K562 erythroleukemia cells but does not result in apoptosis

Astronauts and experimental animals in space develop the anemia of space flight, but the underlying mechanisms are still unclear. In this study, the impact of simulated microgravity on proliferation, cell death, cell cycle progress and cytoskeleton of erythroid progenitor-like K562 leukemia cells was observed. K562 cells were cultured in NASA Rotary Cell Culture System (RCCS) that was used to simulate microgravity (at 15 rpm). After culture for 24 h, 48 h, 72 h, and 96 h, the cell densities cultured in RCCS were only 55.5%, 54.3%, 67.2% and 66.4% of the flask-cultured control cells, respectively. The percentages of trypan blue-stained dead cells and the percentages of apoptotic cells demonstrated no difference between RCCS-cultured cells and flask-cultured cells at every time points (from 12 h to 96 h). Compared with flask-cultured cells, RCCS culture induced an accumulation of cell number at S phase concomitant with a decrease at G0/G1 and G2/M phases at 12 h. But 12 h later (from 24 h to 60 h), the distribution of cell cycle phases in RCCS-cultured cells became no difference compared to flask-cultured cells. Consistent with the changes of cell cycle distribution, the levels of intercellular cyclins in RCCS-cultured cells changed at 12 h, including a decrease in cyclin A, and the increasing in cyclin B, D1 and E, and then (from 24 h to 36 h) began to restore to control levels. After RCCS culture for 12–36 h, the microfilaments showed uneven and clustered distribution, and the microtubules were highly disorganized. These results indicated that RCCS-simulated microgravity could induce a transient inhibition of proliferation, but not result in apoptosis, which could involve in the development of space flight anemia. K562 cells could be a useful model to research the effects of microgravity on differentiation and proliferation of hematopoietic cells.     

大学生诚信缺失的对策探讨

T cell regulation in microgravity – The current knowledge from in vitro experiments conducted in space,parabolic flights and ground-based facilities

Dating back to the Apollo and Skylab missions, it has been reported that astronauts suffered from bacterial and viral infections during space flight or after returning to Earth. Blood analyses revealed strongly reduced capability of human lymphocytes to become active upon mitogenic stimulation. Since then, a large number of in vitro studies on human immune cells have been conducted in space, in parabolic flights, and in ground-based facilities. It became obvious that microgravity affects cell morphology and important cellular functions. Observed changes include cell proliferation, the cytoskeleton, signal transduction and gene expression. This review gives an overview of the current knowledge of T cell regulation under altered gravity conditions obtained by in vitro studies with special emphasis on the cell culture conditions used. We propose that future in vitro experiments should follow rigorous standardized cell culture conditions, which allows better comparison of the results obtained in different flight- and ground-based experiment platforms.
