METHODS: Mouse embryonic stem cells(ESCs) labeled with enhanced yellow fluorescent protein were cultured in three-dimensional(3-D) self-assembling scaffolds and compared with traditional two-dimentional(2-D) culture techniques requiring mouse embryonic fibroblast feeder layers or leukemia inhibitory factor. 3-D scaffolds encapsulating ESCs were prepared by mixing ESCs with polyethylene glycol tetra-acrylate(PEG-4-Acr) and thiolfunctionalized dextran(Dex-SH). Distribution of ESCs in 3-D was monitored by confocal microscopy. Viability and proliferation of encapsulated cells during long-term culture were determined by propidium iodide as well as direct cell counts and PrestoB lue(PB) assays. Genetic expression of pluripotency markers(Oct4, Nanog, Klf4, and Sox2) in ESCs grown under 2-D and 3-D cultureconditions was examined by quantitative real-time polymerase chain reaction. Protein expression of selected stemness markers was determined by two different methods, immunofluorescence staining(Oct4 and Nanog) and western blot analysis(Oct4, Nanog, and Klf4). Pluripotency of 3-D scaffold grown ESCs was analyzed by in vivo teratoma assay and in vitro differentiation via embryoid bodies into cells of all three germ layers. RESULTS: Self-assembling scaffolds encapsulating ESCs for 3-D culture without the loss of cell viability were prepared by mixing PEG-4-Acr and Dex-SH(1:1 v/v) to a final concentration of 5%(w/v). Scaffold integrity was dependent on the degree of thiol substitution of Dex-SH and cell concentration. Scaffolds prepared using Dex-SH with 7.5% and 33% thiol substitution and incubated in culture medium maintained their integrity for 11 and 13 d without cells and 22 ± 5 d and 37 ± 5 d with cells, respectively. ESCs formed compact colonies, which progressively increased in size over time due to cell proliferation as determined by confocal microscopy and PB staining. 3-D scaffold cultured ESCs expressed significantly higher levels(P < 0.01) of Oct4, Nanog, and Kl4, showing a 2.8, 3.0 and 1.8 fold increase, respectively, in comparison to 2-D grown cells. A similar increase in the protein expression levels of Oct4, Nanog, and Klf4 was observed in 3-D grown ESCs. However, when 3-D cultured ESCs were subsequently passaged in 2-D culture conditions, the level of these pluripotent markers was reduced to normal levels. 3-D grown ESCs produced teratomas and yielded cells of all three germ layers, expressing brachyury(mesoderm), NCAM(ectoderm), and GATA4(endoderm) markers. Furthermore, these cells differentiated into osteogenic, chondrogenic, myogenic, and neural lineages expressing Col1, Col2, Myog, and Nestin, respectively. CONCLUSION: This novel 3-D culture system demonstrated long-term maintenance of mouse ESCs without the routine passaging and manipulation necessary for traditional 2-D cell propagation.展开更多

The terminal lung tissue of the rat was taken out and minced. Then 0.5 % of type Ⅳ collagenase solution was added for digestion and the microvascular segments were obtained by screening. The targeted cells were cultured by “selective conditioned media”. Under phase contrast microscope, the cultured cells were large in size with ragged margin and numerous pseudopodia, which imparted tubule like structure. There was no contact inhibition in growing cells, so multiple layers developed. When they were confluent, there were morphologically no “hillock and dale” growth pattern as in smooth muscle cells or “weave like” pattern as in fibroblasts. The ultrastructure of cultured cells showed numerous digital processes, moderate amount of rough and smooth endoplasmic reticulum, rich Golgi's apparatus, microfilaments, few lysosomes without myofilaments and dense bodies. Immunohistochemical staining revealed that the cultured pericytes had same kind of cellular skeletal protein, α SM actin, like smooth muscle cells. The cultured cells also exhibited positive reaction to CD 34 antigen and S 100 antigen, which were negative in smooth muscle cells and fibroblasts. The cell growth pattern, ultrastructure and immunological phenotype suggested that the cultured cells had characteristics of vascular pericytes. Pericytes are one of the components of microvascular cells, and the establishment of in vitro culture technique of pericytes is of significance for further exploration of the muscularization of non muscular arterioles in lung and the mechanism of structural remodeling of pulmonary vessels.展开更多

It was highlighted that the Hakka's enclosed houses in south Jiangxi has diversified architectural styles and outstanding defensive and living functions. Construction art and religious culture shown by the enclosed houses were interpreted, and the branch of Han people with unique dialects, cultures, folk customs and emotional attitudes was proposed as a miniature of the culture in south Jiangxi. Moreover, it was stressed that more attention of the public and more efforts for the protection should be given to the Hakka's cultures in south Jiangxi, carriers of the locals' history over the past thousands of years.展开更多

To get out of it, it is necessary to dig deeper in the study of aesthetics. The fact that the marginal areas' cultural heritage, agricultural culture, industrial culture and post-industrial culture often coexist in a harmonious way in a nation or the same area attracts the attention of aesthetic anthropologists. The paper mainly analyzes the constructive relationship between the culture of marginal areas and aesthetic anthropology, and discusses how to establish a relationship between them with the help of the development model of Yunnan's marginal culture.展开更多

METHODS: Rat hepatocytes were incubated with AG, L-NAME, L-NNA, Actinomycin D (ActD) and dexamethasone in a medium containing CM (LPS plus TNF-alpha, IL-1 beta, and IFN-gamma) for 24h. NO production in the cultured supernatant was measured with the Griess reaction. Intracellular cGMP level was detected with radioimmunoassy. RESULTS: NO production was markedly blocked by AG and L-NAME in a dose-dependent manner under inflammatory stimuli condition triggered by CM in vitro. The rate of the maximum inhibitory effects of L-NAME (38.9%) was less potent than that obtained with AG(53.7%, P 【 0.05). There was no significant difference between the inhibitory effects of AG and two L-arginine analogues on intracellular cGMP accumulation in rat cultured hepatocytes. Non-specific NOS expression inhibitor dexamethasone (DEX)and iNOS mRNA transcriptional inhibitor ActD also significantly inhibited CM-induced NO production. AG(0.1 mmol x L(-1)) and ActD (0.2 ng x L(-1)) were equipotent in decreasing NO production induced by inflammatory stimuli in vitro, and both effects were more potent than that induced by non-selectivity NOS activity inhibitor L-NAME (0.1 mmol x L(-1)) under similar stimuli conditions (P【0.01). CONCLUSION: AG is a potent selective inhibitor of inducible isoform of NOS,and the mechanism of action may be not only competitive inhibition in the substrate level, but also the gene expression level in rat hepatocytes.展开更多

文摘With the gradual improvement of Chinese women’s status in the 21st century,gender studies and gender relations have become one of the hottest topics in Chinese society,which consequently prompted Chinese Women’s Cinema to attract the attention of larger audiences.With regard to the box office performance of Chinese Women’s Cinema,there seems to be a gap in research in finding an association between women’s status and the relevant films’box office performance.The purpose of this research is to outline the underlying reasons for the changes in gender roles and gender representation in the Chinese film industry over the past few decades in order to better understand this expansive social change in the 21st century.This study provides a comprehensive analysis through the use of questionnaires to better understand society’s attitude towards gender representation within the film industry.The questionnaire findings indicate that there is a direct correlation between people’s awareness of women’s changing status and gender equality and their acceptance of materials produced by Chinese Women’s Cinema.At the some time,it highlights that the Chinese government’s support and initiatives for gender equality have had a significant impact on the general popularity of Chinese Women’s Cinema.The significance of this research is to effectively popularize Chinese Women’s Cinema culture and the box office growth by understanding the social attitude towards gender representation in the Chinese film industry and to provide relevant information about the development direction and trend of Chinese Women’s Cinema.Furthermore,this research aims to provide foundational support for gender equality and help to understand the underlying factors that society needs to promote gender equality.
文摘General situation and distribution of round houses of the Hakka in south Jiangxi were introduced, such architectural styles as enclosed house with a square yard (kouzi wei, in the shape of 口), enclosed house with a yard of three transverse and one longitudinal constructions (guozi wei, in the shape of 国), and enclosed house with a round house in its yard (tao wei) were taken to analyze features of the Hakka's enclosed houses. It was highlighted that the Hakka's enclosed houses in south Jiangxi has diversified architectural styles and outstanding defensive and living functions. Construction art and religious culture shown by the enclosed houses were interpreted, and the branch of Han people with unique dialects, cultures, folk customs and emotional attitudes was proposed as a miniature of the culture in south Jiangxi. Moreover, it was stressed that more attention of the public and more efforts for the protection should be given to the Hakka's cultures in south Jiangxi, carriers of the locals' history over the past thousands of years.
文摘Rural tourism was a new form of tourism gradually emerging in China in recent years. It satisfied urban residents' pursuit of nature and had a promising market prospect. New rural construction of socialism was an important historical task in the process of economic and social development of China at present and in future period. New rural construction was the important basis of rural tourism development and meanwhile rural tourism development could promote new rural construction. Shanxi Merchant's Culture of Xi Village in Jinzhong City was a kind of excellent rural tourism resource. Developing rural tourism was one of the effective ways to promote new rural construction of socialism in Xi Village.

文摘At the turn of the century, the development of aesthetics encounters severe challenges and is trapped in a crisis. To get out of it, it is necessary to dig deeper in the study of aesthetics. The fact that the marginal areas' cultural heritage, agricultural culture, industrial culture and post-industrial culture often coexist in a harmonious way in a nation or the same area attracts the attention of aesthetic anthropologists. The paper mainly analyzes the constructive relationship between the culture of marginal areas and aesthetic anthropology, and discusses how to establish a relationship between them with the help of the development model of Yunnan's marginal culture.

文摘AIM: To study the effects of aminoguanidine (AG) and two L-arginine analogues N(omega)-nitro-L-arginine methyl ester (L-NAME) and N(omega)-nitro-L-arginine (L-NNA) on nitric oxide (NO) production induced by cytokines (TNF-alpha, IL-1 beta, and IFN-gamma) and bacterial lipopolysaccharide (LPS) mixture (CM) in the cultured rat hepatocytes, and examine their mechanisms action. METHODS: Rat hepatocytes were incubated with AG, L-NAME, L-NNA, Actinomycin D (ActD) and dexamethasone in a medium containing CM (LPS plus TNF-alpha, IL-1 beta, and IFN-gamma) for 24h. NO production in the cultured supernatant was measured with the Griess reaction. Intracellular cGMP level was detected with radioimmunoassy. RESULTS: NO production was markedly blocked by AG and L-NAME in a dose-dependent manner under inflammatory stimuli condition triggered by CM in vitro. The rate of the maximum inhibitory effects of L-NAME (38.9%) was less potent than that obtained with AG(53.7%, P 【 0.05). There was no significant difference between the inhibitory effects of AG and two L-arginine analogues on intracellular cGMP accumulation in rat cultured hepatocytes. Non-specific NOS expression inhibitor dexamethasone (DEX)and iNOS mRNA transcriptional inhibitor ActD also significantly inhibited CM-induced NO production. AG(0.1 mmol x L(-1)) and ActD (0.2 ng x L(-1)) were equipotent in decreasing NO production induced by inflammatory stimuli in vitro, and both effects were more potent than that induced by non-selectivity NOS activity inhibitor L-NAME (0.1 mmol x L(-1)) under similar stimuli conditions (P【0.01). CONCLUSION: AG is a potent selective inhibitor of inducible isoform of NOS,and the mechanism of action may be not only competitive inhibition in the substrate level, but also the gene expression level in rat hepatocytes.

文摘Clarifying China’s position in the global system is an important logical basis for developing national diplomacy.Although much research has been done on China’s development status,most studies have been based on country comparisons or institutional en-vironment.In today’s networked era in which the global economy,trade,personnel,and information are closely connected,studies on China’s global position and its status changes and influencing factors in multiple contact networks are still insufficient.In this study,from the perspective of diverse global contact networks,we constructed economic,cultural,and political influence indices to explore the changes and influencing factors on China’s status in the global system from 2005 to 2018.The results show that during the study period,China’s global influence in the fields of economic ties,cultural exchanges,and political contacts increased significantly,but its influ-ence in the fields of cultural exchanges and political contacts lagged far economic ties.The pattern of China’s economic influence on various economies around the world has shown a transformation from an‘upright pyramid’to an‘inverted pyramid’structure.The proportion of these economies in low-influence zones has decreased from more than 60%in 2005 to less than 20%in 2018.China’s cultural and political influence on various economies around the world has increased significantly;however,for the former,the percentage of high-influence areas is still less than 20%,whereas for the latter the percentage of these economies in medium-and high-influence areas is still less than 50%.Analyses such as a scatter plot matrix show that geographical proximity,economic globalization,close cooperation with developing countries,and a proactive and peaceful foreign policy are important factors in improving China’s status in the diverse global network system.
文摘In the process of development, especially in the context of modernization and globalization, cultural heritage in Vietnam is facing many challenges and difficulties in resolving relationships between conservation and development, safeguarding and exploitation, economic and cultural goals, the roles of the government and the community, political and cultural factors. By studying the cases of some elements that UNESCO has inscribed on the Representative List of the Intangible Cultural Heritage of Humanity and List of the World Heritage Sites in Vietnam (including Vietnamese Court Music, Xoan Singing of Phu Tho province, Worship of Hung Kings in Phu Tho, the Cultural Space of the Gongs in the Central Highlands of Vietnam, Ha Long Bay, Trang An Landscape Complex and Complex of Hue Monuments), this paper aims to analyze the specific issues in the above relationships in order to clarify the challenges that the heritage is facing in compliance with the UNESCO’s Conventions on the safeguarding of cultural heritage as well as towards the sustainable development.
