新疆地区活体肾移植178例随访

背景:新疆的特殊之处在于是国内少数民族与汉族混杂聚集地,新疆地区目前尚无少数民族与汉族间活体肾移植有种族差异的明确报道。目的:比较新疆地区少数民族与汉族间活体肾移植的种族差异。方法:回顾性分析新疆地区1999/2010行活体肾移植受者的临床资料,并对移植前、后一般临床资料,以及移植后少数民族与汉族间移植肾存活率进行比较分析,将可能影响移植肾存活率的各种因素进行单因素分析。结果与结论:纳入随访资料完善者178例,其中少数民族131例,汉族47例。汉族组受者的移植肾存活率较少数民族组患者稍高,但差异无显著性意义。对可能影响长期移植肾生存的因素进行Cox单因素分析,显示急性排斥反应对移植肾生存有明显影响。提示新疆地区不同民族间接受同种民族活体肾移植的短中期移植肾存活率差异无显著性意义,急性排斥反应为影响移植肾存活的重要因素。

Melanocortin-1 receptor gene variants in four Chinese ethnic populations

There is strong relationship between melanocortin-1 receptor (MCIR) gene variants and human hair color and skin type. Based on a sequencing study of MC1R gene in 50 individuals from the Uygur, Tibetan, Wa and Dai ethnic populations, we discuss the occurrence of 7 mc1r variants consisting of 5 nonsynonymous sites (Val60Leu, Arg67Gln, Val92Met, Arg163Gln and Ala299Val) and 2 synonymous sites (C414T and A942G), among which C414T and Ala299Val were reported for the first time. Confirmation and analysis were the made of 122 individuals at three common point mutations (Val92Met, Arg163Gln, A942G) using PCR-SSCP. The frequency of Arg163Gln variant varies in the four ethnic populations, with percentage of 40%, 85.0%, 66. 2% and 72.7%, respectively, while those of Val92Met and A942G are roughly similar in these four populations. The different environments, migration and admixture of various ethnic groups in China might have impact on the observed frequency of Arg163Gln.

The Social Limitations in the Development of Asian American Literature

This paper traces the social limitations in the development of Asian American literature. The label ＂Asian American literature＂ is so instrumental in instituting the literature, can also regulate creativity. As a strategic term and group identification, ＂Asian American＂ lends itself to the illusion of unity and homogeneity. Scholars differ in the way they elect to demarcate Asian American literature. One of the fundamental barriers to understanding and appreciating Asian American literary expression has been the existence of race stereotypes about Asians in American popular culture. For many Asian American writers, ethnic authenticity is a necessary but weak choice Most early immigrant writers write to challenge the negative view of Asia in the West and see themselves as ambassadors of goodwill to the West. The purpose is to mark difference as exotica and appeal to the benign curiosity of the Western readers while appeal to notions of universal humanity. This type of strong ethnic quotient writing continues to exist in various guises even today. The trade publishers have a predilection for Asian American personal narratives that stress the ＂model minority＂ discourse, ＂good workers＂ image, and Asian Americans＇ ability to accommodate to the basic rules of American society. Asian American writers never stop attempting to build bridges. But we should remind ourselves that boundary crossing must not be merely an aesthetic and intellectual exercise .

Lusitan Identity Paradoxes Revealed by Fado Songs

This paper briefly presents the methods and the results of the investigation conducted within the doctoral study. The goal is to investigate the phenomenon of fado songs in the context of cultural transformations that take place in the uniting Europe. During the investigation, we tried to verify the problem of national and cultural identity of the Portuguese and their attitude towards ethno-cultural auto-identification in fado. According to the research results, the Portuguese are profoundly conscious of the relation between fado and their national and cultural identity. The results show that the Portuguese also consider the songs so strongly tied to their own nation, history, and places in Portugal, that this makes impossible for the foreigners to understand the message （even though some listeners claim, that they ＂feel＂ fado, though not being able to understand the lyrics）. The research results proved that the Portuguese consider fado as a carrier of their identity, or even ＂Portuguese soul＂.

Political Identity: A Perspective from Cultural Identity

Identity is the ＂sameness＂ and belonging of identification. In a real sense, cultural identity is often related to ethno-cultural identity, while political identity and national identity are more often inseparable. Cultural identity lays particular stress on the group destiny of a people or ethnic group from which its members cannot withdraw. Political identity, on the other hand, highlights the subjective values and intentions chosen, judged and assessed by the members of society. Since modem times, politics, as the surface of the social structure, has demonstrated increasingly serious conflict and perplexity, and the decline of the political identity has gradually developed into a common social phenomenon. Considering the high complementarity and the mutual stimulation between cultural identity and political identity, we should take cultural identity as the pivot for our entry into the actual practice of community politics, with a view to promoting institutional innovations, making interest adjustments, and intensifying the community members＇ sense of belonging. These are exceptionally meaningful for strengthening the political identity of a community.

National Identity in the Context of Globalization:A Structural Perspective

In this era of ＂liquid modernity,＂ China faces the dual pressures of external globalization and internal social transformation. Within these dual space-time coordinates, academic research should address the question of what makes national identity possible by moving away from its fixation on macro-narratives and concrete micro-analysis of civic or ethnic identity, etc., to focus on meso-analysis. To do this, it is important to allay individuals＇ ontological anxiety so that they return to ontological security; to realize the production and reproduction of a national centripetal force; and to highlight the functional power of national identity. Both theoretical studies and real-world experience show that national identity cannot play a stable and coherent role on its own, but needs the structural support of three fundamental systems： economic incentives, political values, and institutional organization. The functional cohesion of these systems provides an effective path to the realization of national identity.

Teaching to, with, and Against the Test: Language Teaching and Teacher Identity Under Institutional Neoliberalization

Neoliberalism has emerged as a keyword that captures some core features of global economic and educational reforms in recent years. This paper reports a linguistic ethnographic study of how a Chinese language teacher was engaged with neoliberal discourses on language education in and out of the classroom in a suburban public middle school in China, with an attempt to illuminate the complexity of language education in a neoliberal context. The analysis shows three general identity positions-as an opponent, a conformist, and a pragmatist-across the identification trajectory of the focal language teacher through the fieldwork period, in relation to neoliberal exam-oriented education and her various ways of engaging with exam discourses in her language classrooms. This inquiry argues for the perspective of unpredictability and complexity as an alternative that goes beyond the current "deterministic neoliberalism" in understanding the dynamics of neoliberalization in language education, language teaching, and teacher identity formation.

The Chinese Dream： Imagining China

This article will discuss how the official discourse on the Chinese Dream is transformed in the meeting with the public in China. The Chinese Dream will be discussed both as a political framing discourse and as a public communication campaign in order to understand how the very selective responsiveness to the central theme of the Chinese Dream, the great rejuvenation of the Chinese Nation, influences the impact of the Dream discourse. An analysis of a selection of posts from Sina Weibo demonstrates how the Dream discourse contributes to national identity building, or in Benedict Anderson＇s words （in Imagined communities： Reflections on the origin and spread of nationalism, 1991）： to the imagined community that is China.

A Note on Heegaard Genus of Self-amalgamated 3-Manifold

Let M be a connected orientable compact irreducible 3-manifold. Suppose that αM consists of two homeomorphic surfaces F1 and F2, and both F1 and F2 are compressible in M. Suppose furthermore that g(M, F1) = g(M) + g(F1), where g(M, F1)is the Heegaard genus of M relative to F1. Let Mfbe the closed orientable 3-manifold obtained by identifying F1 and F2 using a homeomorphism f : F1 → F2. The authors show that if f is sufficiently complicated, then g(Mf) = g(M, αM) + 1.
