A Study of the Children Reality TV Show Grade One from the Perspective of Narratology

电视的叙事能力是电视节目的核心竞争力。《一年级》作为湖南卫视推出的一档全新自制的儿童真人秀节目，被认为是真人秀节目向上提升的标志性作品。故事围绕七名学生与两位“明星”实习老师展开叙述。《一年级》之所以获得成功，电视故事的叙事能力是关键。 因此，本文以《一年级》的电视叙事能力为出发点。从叙事学的角度，结合具体的节目做个案的文本分析。在经典叙事学的范畴，研究讨论了《一年级》的叙事结构和叙事话语，解读其故事结构和故事母题，又借鉴5W模式对其叙述者、叙述载体、叙事时间和叙事空间做综合分析，旨在理清《一年级》讲了什么好故事和如何讲出好故事。此外，本文还从后经典叙事学的角度，将《一年级》的叙事与当前的社...Grade One, a brand new children reality show originated and promoted by the Hunan Satellite TV, has drawn great attention in China since its premiere. By “finding a balance between variety show and education”, it is believed to be a landmark program of the improving Chinese reality shows. The Grade One narrates the story of seven pupils and two “celebrity” teachers. The narrative ability of the Gr...学位：文学硕士院系专业：新闻传播学院_传播学学号：3192012115281

Influence of berberine on hyperandrogenism of rats with polycystic ovarian syndrome and StAR protein expression

目的:研究黄连素对多囊卵巢综合征(PCOS)大鼠治疗作用及机制。方法:将48只6周龄SPF级雌性SD大鼠随机分为空白对照组和造模组,造模组采用来; 曲唑(1mg·kg~(-1)·d~(-1))灌胃诱导PCOS模型。造模结束后,将造模成功的大鼠随机分为模型对照组、二甲双胍组、黄连素组,每组11; 只。治疗期间空白对照组、模型对照组均用1%羧甲基纤维素灌胃,二甲双胍组用1%羧甲基纤维素+二甲双胍(135mg·kg~(-1)·d~(-1))灌; 胃,黄连素组用1%羧甲基纤维素+黄连素(81mg·kg~(-1)·d~(-1))灌胃。测定大鼠血清睾酮、空腹胰岛素,光镜下观察大鼠卵巢HE染色病; 理片和StAR免疫组化病理片。结果:本实验模型大鼠出现典型的PCOS表现:卵巢呈多囊样改变;血清睾酮升高(P<0.05);空腹胰岛素升高(P<0; .01),提示存在胰岛素抵抗。二甲双胍和黄连素均能改善模型大鼠的胰岛素抵抗,但黄连素降低睾酮的能力优于二甲双胍(P<0.05)。卵泡膜细胞的细胞; 膜上StAR密度随睾酮值升高而升高。结论:黄连素有治疗PCOS的作用,它不仅能改善胰岛素抵抗,还能通过降低卵泡膜细胞的细胞膜上StAR密度降低血; 清睾酮值,治疗高雄激素血症。Objective: To study the therapeutic effect and mechanism of berberine on; rats with polycystic ovarian syndrome. Methods: Forty-eight six-week SPF; female SD rats were randomly divided into blank control group and model; group. The model group received letrozole to induce PCOS model, then the; successful modeling rats undergone were divided into model control; group, melbine group and berberine group. During the treatment, 1%; carboxymethylcellulose was used on the blank control group and model; control group, 1% carboxymethylcellulose plus melbine were used on the; melbine group while 1% carboxymethylcellulose plus berberine were used; on the berberine group. The testosterone and fasting insulin of rats; were detected, the ovarian pathological slices of HE staining and the; StAR immunohistochemical pathological slices of rats were observed under; light microscopes. Results: In this experiment, the model rats have; typical PCOS manifestations: the ovary has polycystic changes; the; testosterone rises (P<0.05); the fasting insulin rises (P<0.01), which; indicate that insulin resistance exists. Both melbine and berberine can; improve the insulin resistance of model rats, but the performance of; berberine in lowering androgen is better than melbine. The testosterone; of PCOS hyperandrogenism is positively related to the StAR density on; the cytomembrane of theca cells. Conclusion: Berberine has effect on; PCOS. It can not only improve insulin resistance but also treat; hyperandrogenism by lowering the StAR density on the cytomembrane of; theca cells to decrease the testosterone.福建省漳州市自然科学基金项

龙眼APETALA1(AP1)同源基因的克隆与序列分析

根据植物APETALA1(AP1)同源基因的高度保守性,设计合成一对特异引物,从龙眼基因组DNA中扩增出一条长400bp左右的基因片段,插入到pMD-T载体中。测序后分析表明,扩增得到了龙眼AP1同源基因片段。该片段序列包含两个内含子(长96bp和165bp),编码区编码36个氨基酸。与其它植物AP1同源基因的相应区域氨基酸序列具有较高的同源性,其中与花椰菜AP1基因同源性高达91%,与欧亚种葡萄、苹果、柑橘、枇杷的AP1基因同源性都在80%以上。福建省农业科技重大专项资助项目“闽台果茶良种选育研究及产业化”(2004NE02-1
