职场表演的自由与规范——《中国娃娃》的社会表演学解读

Objective: Ovarian cancer is the most fatal gynecological malignant tumor, and it is particularly important for the early diagnosis of ovarian cancer. However, the lack of specific tumor markers has become a major problem in the early diagnosis of ovarian cancer. There is increasing evidence that abnormal methylation of gene promoter plays an important role in the carcinogenic process and can silence gene expression, which is an early event in the pathogenesis of ovarian cancer. The gene promoter methylation found in tumor can be reflected in circulating cell-free DNA(cfDNA) released from tumor to peripheral blood, which is consistent with primary tumor, making cfDNA methylation a noninvasive molecular marker based on blood detection. PRDM2 is closely related to the occurrence and development of tumor, and related research has made great progress, which has the potential as a molecular marker. Therefore, this study will explore the expression and clinical significance of PRDM2 gene promoter methylation in ovarian cancer tumor tissues and plasma ***: The tumor tissues from 56 ovarian cancer patients and 36 normal ovarian tissues were collected admitted to the affiliated Cancer Hospital of Harbin Medical University. The corresponding preoperative plasma samples were collected. The expression of PRDM2 mRNA and protein in ovarian tissues was detected by Real-time quantitative PCR(qPCR) and Western-blot, the status of PRDM2 gene promoter methylation in ovarian tissues was detected by methylation specific PCR(MSP), and the correlation between gene expression and its promoter methylation was analyzed. The status of PRDM2 gene promoter methylation inplasma cfDNA was detected by MSP, and the correlation of PRDM2 gene methylation changes in plasma cfDNA and ovarian tissues was analyzed. Moreover, to explore the relationship between PRDM2 gene promoter methylation and clinicopathological features of ovarian cancer patients, and to evaluate the diagnostic value of PRD

《中国娃娃》通过美国华裔女演员黄柳霜的演艺经历再现了20世纪美国少数族裔演员面临的困境。以社会学和表演的双重视角来观照剧中人物黄柳霜的职场表演,能够从自由、规范和面具三个层面展示她的职业选择和困境背后错综复杂的关系。自由表演是个人按照自己意愿进行的社会表演,注重人的个性。黄柳霜通过自由表演突破传统,实现了演员梦想。规范强调角色背后的各种社会关系制约,使得黄柳霜进入职场后不得不遵循美国主流社会规范,借助面具保障其社会表演的顺利进行。这折射出美国少数族裔演员饰演刻板角色的深层原因——社会规范限制少数族裔演员的自由表演,使其成为反衬美国主流文化中心地位的参照物,误导了观众对他们演艺事业的认知。

Background:Endothelial progenitor cells(EPCs) play a important role in tumor angiogenesis and *** prior study indicated that over-expressed inhibitor of DNA binding/differentiation 1(Id1) in EPCs can promote EPCs proliferation,migration,and *** this study,we assessed the effect of MicroRNAs(miRNAs) on EPCs angiogenesis and its signaling pathway in patients suffered from ovarian cancer(OC).Methods:We cultured peripheral circulating EPCs derived from 32 OC patients and 20 healthy control subjects,respectively..miRNA profiles from EPCs with ovarian cancer patients were compared with that from healthy control subjects,and aberrantly expressed miRNAs in both groups were identified via miRNA microarray and clustering *** the miRNAs,miR-133 was considered as one of the most important miRNAs,which biological function in EPCs was *** revealed the target protein of miR-133,bioinformatic analysis,combined with knockdown and overexpression of miR-133 was ***:We found that miR-133 was an important upstream factor regulated VEGF/Id1 expression,and it appeared a low expression in EPCs with ovarian cancer ***,functional studies revealed that FOXC1 was a direct target protein of miR-133,and FOXC1 silencing attenuated the role of miR-133 in angiogenesis and VEGF/Id1 ***:The study suggested the down-regulated miR-133 may contribute to EPCs angiogenesis with ovarian cancer by increasing FOXC1 expression,so we proposed that miR133 would be a new target in OC therapy.

少数族裔女性在美国的生活是异常艰辛复杂的。残酷的种族歧视打破了她们进入主流社会的愿望。为了得到认可,她们采取迎合主流观众期待的社会表演。然而,这种行为让她们落入了殖民者模拟策略的陷阱,形成了扭曲的客我。理想化表演造成的文化误解只能靠重塑主我才能解开。本文以薇莉娜·哈苏·休斯顿的《茶》为研究对象,探讨剧中五位"战争新娘"的社会表演,以及她们在平衡主我和客我的过程中寻求到的安身立命之道。
