Lu Xun in the Rhetoric of the Sino-Soviet Split： A View from Contemporary Russia

Frontiers of Literary Studies in China-Selected Publications from Chinese Universities 2013年第3期7卷 483-493页

作者： olga Medvedeva Department of AHKR University of Bergen Postbox 7805 NO-5020 Bergen Norway

The historical role of the prominent Chinese writer, social activist and thinker Lu Xun （1881-1936）, is difficult to overestimate. His works influenced social change within China and became recognized internationally. For these and other reasons, he was of particular interest in the Soviet Union. Since 1932, his works have been published in numerous editions in Russian and have received a great deal of scholarly attention in the Soviet Union. Such unprecedented attention was initially based on the idea that he held similar revolutionary sentiments to those prevailing in the Soviet Union. Later, from the second half of the 1960s to the early 1970s, the ideological disagreements between the Soviet Union and China influenced the direction of Lu Xun studies in the Soviet Union. Soviet leader Khrushchev called for peaceful coexistence with the capitalist West, while Mao Zedong stressed the universal character of the proletarian revolution. Lu Xun was highly respected in both the USSR and China, and thus became an influential tool in this polemic. But, for Soviet scholars, this renewed focus on Lu Xun offered an opportunity to provide a new perspective on the writer＇s works. This paper analyzes how the Sino-Soviet split influenced Russian academics＇ positions on Lu Xun. The focus is on the three main points of contention in the ideological disagreements between the PRC and the USSR. First, Soviet critics focused on the psychological aspects and individualism in the Lu Xun＇s works. Second, a special focus on humanistic elements in the writer＇s ideas can be seen as a result of the Soviet disagreement with the Cultural Revolution＇s period. Third, by pointing to the internationalist aspects of Lu Xun＇s writings, Soviet scholars attempted to expose the Sinocentric political attitudes of the ruling circles in China.

Novel screening test for celiac disease using peptide functionalised gold nanoparticles

AIM To develop a screening test for celiac disease based on the coating of gold nanoparticles with a peptide sequence derived from gliadin, the protein that triggers celiac ***20 nm gold nanoparticles were first coated with NeutrAvidin. A long chain Polyethylene glycol(PEG) linker containing Maleimide at the Ω-end and Biotin group at the α-end was used to ensure peptide coating to the gold nanoparticles. The maleimide group with the thiol(-SH) side chain reacted with the cysteine amino acid in the peptide sequence and the biotinylated and PEGylated peptide was added to the NeutrAvidin coated gold nanoparticles. The peptide coated gold nanoparticles were then converted into a serological assay. We used the peptide functionalised gold nanoparticle-based assay on thirty patient serum samples in a blinded assessment and compared our results with the previously run serologicaland pathological tests on these *** A stable colloidal suspension of peptide coated gold nanoparticles was obtained without any aggregation. An absorbance peak shift as well as color change was caused by the aggregation of gold nanoparticles following the addition of anti-gliadin antibody to peptide coated nanoparticles at levels associated with celiac disease. The developed assay has been shown to detect anti-gliadin antibody not only in quantitatively spiked samples but also in a small-scale study on real non-hemolytic celiac disease patient's *** The study demonstrates the potential of gold nanoparticlepeptide based approach to be adapted for developing a screening assay for celiac disease diagnosis. The assay could be a part of an exclusion based diagnostic strategy and prove particularly useful for testing high celiac disease risk populations.
