NHK纪录片的中国表征与价值取向

NHK以纪录片形式对中国持久而强烈的关注在世界电视机构中无出其右。NHK对中国的表征视域是以中国题材对日本自身的价值意义关联来确定的,是其自身文化价值、历史观念和现实利益的一种"映射"。对NHK纪录片的中国表达,不能简单地仅运用单一的内容分析法贴上正面或负面标签,而应该从历史流变和现实场域的复杂关系中进行历史和逻辑考查。

《周易》之阴阳观在中国山水画中的笔墨表征探究

《周易》学说中的“阴阳”是周易哲学的基本内核。阴阳观中,阴阳气化是构成宇宙万物交生交感、周流循环、变化无穷的原动力,宇宙万物乃阴阳而生。中国画笔墨有塑万物之象、呈阴阳之理之能,这阴阳气化与中国画意象以及中国画笔墨表征存在着异质同构的关系。中国画的用笔造型、塑势写境、虚实布局等无不体现着阴阳互对互存、相互融合转化的和谐规律。

Characterization of focal liver lesions with SonoVue~-enhanced sonography: International multicenter-study in comparison to CT and MRI

AIM： To evaluate in a multicenter study whether the sonographic characterization of focal liver lesions can be improved using SonoVue-enhancement; and to compare this method with computed tomography （CT） and magnetic resonance imaging （MRI）. METHODS： One hundred and thirty four patients withone focal liver lesion detected in baseline ultrasound （US） were examined with conventional US, contrastenhanced US （n = 134）, contrast-enhanced CT （n = 115） and/or dynamic contrast-enhanced MRI （n = 70）. The lesions were classified as malignant, benign or indeterminate and the type of lesion was determined. The final diagnosis based on the combined information of all imaging examinations, clinical information and histology （n = 32） was used. Comparisons were made to see whether the addition of contrast-enhanced US led to the improvement of the characterization of doubtful focal liver lesions.RESULTS： In comparison with unenhanced US, SonoVue markedly improves sensitivity and specificity for the characterization （malignant/benign） of focal liver lesions. In comparison with CT and/or dynamic MRI, SonoVue -enhanced sonography applied for characterization of focal liver lesions was 30.2% more sensitive in the recognition of malignancy and 16.1% more specific in the exclusion of malignancy and overall 22.9% more accurate. In the subgroup with confirmative histology available （n = 30）, sensitivity was 95.5% （CEUS）, 72.2% （CT） and 81.8% （MRI）, and specificity was 75.0% （CEUS）, 37.5% （CT） and 42.9% （MRI）. The sensitivity and specificity of CEUS for the identification of focal nodular hyperplasia （FNH） and hemangiomas was 100% and 87%, resulting in an accuracy of 94.5%.CONCLUSION： SonoVue-enhanced sonography emerges as the most sensitive, ost specific and thus most accurate imaging modality for the characterization of focal liver lesions.

Pigment characterization for the 2011 bloom in Qinhuangdao implicated "brown tide" events in China

A large-scale bloom occurred from May to June in 2011 in sea area near Qinhuangdao of the Bohai Sea, leading to huge damage of the scallop culture industry. Similar blooms have been observed in this region for three years. The causative species of the bloom, which dominated the phytoplankton community with the maximum cell density around 109 cell/L, could not be identified with morphological features due to the small cell size （-2 μm）. A pigment analytical method was then adopted to analyze the pigment profile of the phytoplankton samples collected from the blooming sea area. It was found that pico-sized （〈2 μm）, nano-sized （2-20 μm）, and bulk phytoplankton samples had similar pigment profile, representing the pigment signature of the bloom-causative species. The major pigments detected included 19-butanoyloxyfucoxanthin （But-fuco）, fucoxanthin （Fuco）, diadinoxanthin （Diad） and chlorophyll a （Chl a）, and high content of But-fuco was the most significant characteristics of the phytoplankton samples. Based on the pigment composition and content, the bloom-causative species could be tentatively identified as pelagophyte, ＂type 8＂ group of haptophyte, or silicoflagellate. Some unique features of the bloom, such as the extremely high cell density, small-sized and But-fuco containing cells, occurring in early summer, and the feeding-cessation effects on scallops, suggest it be a ＂brown tide＂ event similar to those reported in the east coast of the United States of America. The recurrent ＂brown tide＂ events and their dramatic impacts on the shellfish mariculture industry in QirLhuangdao need close attention in the coming years.

Molecular Characterization of Banana streak virus Isolate from Musa Acuminata in China

Banana streak virus （BSV）, a member of genus Badnavirus, is a causal agent of banana streak disease throughout the world. The genetic diversity of BSVs from different regions of banana plantations has previously been investigated, but there are relatively few reports of the genetic characteristic of episomal （non-integrated） BSV genomes isolated from China. Here, the complete genome, a total of 7722bp （GenBank accession number DQ092436）, of an isolate of Banana streak virus （BSV） on cultivar Cavendish （BSAcYNV） in Yunnan, China was determined. The genome organises in the typical manner of badnaviruses. The intergenic region of genomic DNA contains a large stem-loop, which may contribute to the ribosome shift into the following open reading frames （ORFs）. The coding region of BSAcYNV consists of three overlapping ORFs, ORF 1 with a non-AUG start codon and ORF2 encoding two small proteins are individually involved in viral movement and ORF3 encodes a polyprotein. Besides the complete genome, a defective genome lacking the whole RNA leader region and a majority of ORF1 and which encompasses 6525bp was also isolated and sequenced from this BSV DNA reservoir in infected banana plants. Sequence analyses showed that BSAcYNV has closest similarity in terms of genome organization and the coding assignments with an BSV isolate from Vietnam （BSAcVNV）. The corresponding coding regions shared identities of 88% and -95% at nucleotide and amino acid levels, respectively. Phylogenetic analysis also indicated BSAcYNV shared the closest geographical evolutionary relationship to BSAcVNV among sequenced banana streak badnaviruses.

Characterization of Soil Available Nitrogen in the Major Vegetable Production Areas of Pearl River Delta,China

A macro scale survey was performed to investigate the content of soil available nitrogen (N) and its spatial distribution in the main vegetable production areas of the Pearl River Delta.Preliminary enrichment-deficient index of available N was then developed,which was a base for increasing fertilizer application efficiency and vegetable yield as well as for constructing soil testing and fertilizing formula.In general,most of the vegetable growth areas in Pearl River Delta were N-deficient or medium-N-deficient.There was 30%-62% increase in yield of Chinese cabbage on the N-deficient soil after application of N; when soil available N content was less than 145 mg/kg,the yield increased with application of N fertilizer at a rate of 60-70 kg/hm2.

Large-Scale Traffic Characterization of Chinese Multimedia Messaging Service Using Hadoop

Recently, there have been many mo- bile value-added services in the Chinese mo- bile telecommunication market nowadays. Am- ong them, the characteristics of Multimedia Mes- saging Service （MMS） have not yet been fully understood. In this paper, with the help of a cloud computing platform, we investigated the flow-level charactefistcs of Chinese MMS. All of the experimental data were collected by the TMS equipment deployed in a major node in Sou- them China. The collection time spanned six mo- nths. We performed high-level analysis to show the basic distributions of MMS characteristics. Then, by analysing the detailed MMS features, we determined the distribution of personal MMS, and made a comprehensive comparison between 2G and 3G MMS. Finally, we tried to build a model on the personal MMS inter-arrival time, and we found that the Weibull distribution was optimum.

Characterization of 12 polymorphic microsatellite markers in the Chinese tree shrew (Tupaia belangeri chinensis)

The Chinese tree shrew (Tupaia belangeri chinensis) is a small experimental animal with a close affinity to primates. This species has long been proposed to be an alternative experimental animal to primates in biomedical research. Despite decades of study, there is no pure breed for this animal, and the overall genetic diversity of wild tree shrews remains largely unknown. In order to obtain a set of genetic markers for evaluating the genetic diversity of tree shrew wild populations and tracing the lineages in inbreeding populations, we developed 12 polymorphic microsatellite markers from the genomic DNA of the tree shrew. An analysis of a wild population of 117 individuals collected from the suburb of Kunming, China, showed that these loci exhibited a highly expected heterozygosity (0.616). These 12 microsatellites were sufficient for individual identification and parentage analysis. The microsatellite markers developed in this study will be of use in evaluating genetic diversity and lineage tracing for the tree shrew.

Characterization of Intellectuals in Short Stories ofNam Cao （Viemam） and Lu Xun （China）

Nam Cao and Lu Xun are among high-profile writers who gain wide appreciation. The movements of literary assert this over the latter half of recent century in our country. That reality persistently points us to an urgent need for researches on Nam Cao and Lu Xun. Tints of literary worldviews of Nam Cao and Lu Xun, though upon which numberless research works, both domestic and foreign, have provided multi-directional insights and exploration of artistic creativities, remain misevaluated. B ich Thu, the author of Nam Cao, His Life and Legacies, counted out 191 articles and books themed Nam Cao. They were edited by writers of Nam Cao＇s generation namely Nguyen Huy Tuong, Nguyen Dinh Thi, To Hoai and Nguyen Hong, and even distinguished scholars such as Ha Minh Duc, Phong Le and Nguyen Dang Manh, so on. Regarding Lu Xun, there is no denying the fact of his brilliant artistic ideology. Although Vietnamese readers have gained a late knowledge of him for just a half of century, his name is laid somewhere in the heart of our people, integrally and consistently. Vietnam＇s reader generations restlessly learn about and research on Lu Xun. A pioneering merit badge should be rewarded to the renowned literary critic Dang Thai Mai, for his introduction and translation of Lu Xun to Vietnamese readers since 1943. The most interesting coincidence of Nam Cao and Lu Xun is that their profiles are imbued with the characters in their compositions. Mentioning Lu Xun cannot help a reference to AQ, meanwhile the name ofNam Cao apparently recalls a Philistine Chi. AQ as well as Philistine Chi have become characters of the society＇s spiritual life and long live with the eternal brilliance of their two creators. That coincidence draws countless number of researchers. The ＂matching point＂, referring to the subject of farmers and intellectuals, between Nam Cao and Lu Xun＇s works has been explored to some certain extent. This elicitly invites us for deeper studies. The author of this article, in response to such invitation, delves into the subject with respect to characterization of intellectuals in Nam Cao and Lu Xun＇s short stories.

De novo characterization of the root transcriptome of a traditional Chinese medicinal plant Polygonum cuspidatum

Various active components have been extracted from the root of Polygonum cuspidatum. However, the genetic basis for their activity is virtually unknown. In this study, 25600002 short reads （2.3 Gb） of P. cuspidatum root transcriptome were obtained via lllumina HiSeq 2000 sequencing. A total of 86418 urtigenes were assembled de novo and annotated. Twelve, 18, 60 and 54 unigenes were respectively mapped to the mevalonic acid （MVA）, methyl-D-erythritol 4-phosphate （MEP）, shikimate and resveratrol biosynthesis pathways, suggesting that they are involved in the biosynthesis of pharmaceutically important anthra- quinone and resveratrol. Eighteen potential UDP-glycosyltransferase unigenes were identified as the candidates most likely to be involved in the biosynthesis of glycosides of secondary metabolites. Identification of relevant genes could be important in eventually increasing the yields of the medicinally useful constituents of the P. cuspidatum root. From the previously published transcriptome data of 19 non-model plant taxa, 1127 shared orthologs were identified and characterized. This information will be very useful for future functional, phylogenetic and evolutionary studies of these plants.

Distribution characteristics and ecological risk assessment of PAHs in surface waters of China

The concentrations of PAHs in the surface waters from seven river basins in China were summarized from literature published from 2000-2010. Subsequently, the risks from individual PAHs and Y. PAHs in the surface waters of China were quantified by comparing the overlap between the probability distributions of exposure concentrations with the probability distributions of toxicity data. The results show that the concentrations of 15 PAHs in the surface waters ranged from 3.09 to 38139.00 ng L-a, with a geometric mean of 474.93 ng L-1. The significantly higher concentrations of the 15 PAHs occurred in the surface waters from northern China when compared with those from southern China. The concentrations of the 15 PAHs in Chinese surface waters were higher than those in other waters worldwide. The MOSI0 （margin of safety） values were calculated at 90th percen- tile values of exposure concentrations and 10th percentile values of toxicity data, with 5.75, 0.17, 2.33, 0.30, 0.57, 1.74, 1.05, and 0.11 for Ace, Ant, Flu, BaP, Flua, Nap, Phe, and Pyr, respectively. The probabilities of the individual PAH concentrations exceeding the 10th percentile value of the toxicity data were 6.06%, 2.07%, 9.51%, and 2.07% for Nap, Ace, Phe, and Flu, re- spectively, suggesting minimal risk to aquatic organisms; however, the probabilities of BaP, Ant, Flua, and Pyr exceeding this value were 19.49%, 25.46%, 15.15%, and 30.50%, respectively, indicating potential risks. Among the individual PAHs, the ecological risk from Pyr was the highest, followed by, in descending order of risk, Ant, Bap, Flua, Phe, Nap, Flu, and Ace. Additionally, the combined ecological risk of ~ PAH8 in Chinese surface waters was significantly higher than any that of in- dividual PAHs alone. The MOS0 values in the river basins were 〈 1, except for the Haihe River Basin, suggesting a potential combined risk from E PAH8 in the other six fiver basins. The probabilities calculation indicate that low to high ecological risk from E PAH8 for all aquatic species was reported in the Liaohe River Basin （65.58%）, Huaihe River Basin （57.15%）, Songhua River Basin （46.49%）, Pearl River Basin （38.41%）, Yangtze River Basin （25.98%）, Yellow River Basin （15.92%）, and Haihe River Basin （5.22%）.

Gene mutations and clinical phenotypes in Chinese children with Blau syndrome

The mutations of CARD15 gene and clinical features of Chinese patients with Blau syndrome were analyzed. We identified10 missense mutations, out of which five were new: R334 L, E383 D, R471 C, C495 R and D512 F. The rest of them, R334 W,R334Q, G481 D, M513 T and R587 C, have been reported previously. Among all the mutations, R334 W, R334 Q and C495 R had the highest frequency. Blau syndrome was found at early age after birth. It began with lepidic rash and symmetric polyarthritis and was phenotypically characterized by typical rash, arthritis, iridocyclitis and arteritis. Cardiac involvement was also found in Blau syndrome. In addition to nerve deafness, renal involvement, osteochondroma and central nervous system involvement were also found in our patients. Therefore, Chinese children with Blau syndrome have unique gene mutations and complicated clinical phenotypes. Pathologic examination and CARD15 mutation testing should be considered for diagnosis as early as possible for suspected patients.
