Through correlative analysis and path analysis, it finds that (1) the family environment and the colleges and universities environment have direct and indirect influence on self-identity development of students; and (2) the family environment and the colleges and universities environment exert the major effect on self-identity development of students through identity style as mediational variable, so identity style becomes the explanatory base of self-identity status. That is, the predictive effect of diffuse/avoidant identity style for identity diffusion, normative identity style for identity foreclosure, and information identity style for identity achievement respectively is most significant; and (3) family environment that is helpful, supportive, warm, expressive, and promote autonomy and independence possibly makes students form identity achievement or identity moratorium, family environment that is excessively cohesive and warm but lacking independence possibly promote students to form identity foreclosure, and family environment that lacks of supportive and warm possibly make students form identity diffusion; and (4) colleges and universities environments that have better relationship system, clear developmental purpose, and promote to pay attention to societal concerns, critical and explorative qualities, and provide healthy, expressive, democratic, open atmosphere facilitate identity development, in turn form advanced identity. Colleges and universities environments that only emphasize the receival of colleges and universities aims, order and instilments, and scarcely encourage critique, exploration, individuation possibly make students form identity foreclosure. However, the ones that is remote relationship system, and lacking support, and students don't cognize the aim of colleges and universities possibly make students form identity diffusion.

通过相关分析、路径分析发现：(1)家庭环境和学校环境对大学生自我同一性有直接和间接的影响；(2)家庭环境、学校环境对大学生自我同一性影响主要以同一性加工方式为中介变量，同一性加工方式成为自我同一性状态的解释基础，弥散—回避定向同一性风格对弥散型同一性预测力最大，信息定向同一性风格对成就型和延缓型同一性预测力最大，常规定向同一性风格对排他型同一性预测力最大；(3)相互支持、帮助、关心、自由表达和鼓励自主和独立的家庭环境促进大学生同一性的发展，形成成就型或延缓型同一性状态，过度亲密而缺乏独立性特征的家庭环境可能形成排他型同一性状态，而缺乏支持性，关系疏远的家庭环境可能形成弥散同一性状态；(4)良好的关系系统，明确的发展目标，鼓励学生对社会事务关注、倡导批判和探索精神，塑造良好、健康、可供自由表达、民主、开放的文化氛围的大学校园环境促进大学生同一性发展，形成高级、成熟的自我同一性，而一味强调学校目标的接受，强调秩序、灌输，缺乏对批判、探索、个性发展鼓励的学校环境有可能使学生形成排他型同一性状态，但若学校的关系系统疏远，缺乏支持性的民主的风格，目标不能被学生明确感知的学校环境则可能影响学生形成弥散型同一性。

The cloned BBE gene sequences were 94.84% identified with the reported BBE genes in GenBank previously. Based on the cDNA sequences of COR and BBE ,two fragments about 400～500 bp from each gene with lower identity among them were cloned. The fusion gene BC (744 bp) is fused by the PCR technique. Then the promoter CaMV 35S driven, containing'forward BC fusion fragments-reverse pdk intron-reverse BC fusion fragments', plant siRNA expression vector were constructed based on the vectors pHANNIBAL and pART27.The work will lay the foundation for breeding a low morphine and high thebaine poppy.

利用blast及分子生物学软件DNAStar对COR和BBE基因的cDNA序列同源性进行分析比较，分别从各基因中筛选和克隆了一段同源性极低、约400～500 bp的片段；并应用重叠PCR法将其拼接成744 bp的融合基因BC，以中间载体pHANNIBAL和植物表达载体pART27为基础，构建了以CaMV 35S启动子驱动的含有"正向BC融合片段- pdk内含子-反向BC融合片段"的ihRNAi植物表达载体，通过转化野生罂粟，初步研究了以COR和BBE基因为靶标的RNAi对内源吗啡合成的抑制效果，为进一步培育低吗啡高蒂巴因的罂粟种质提供了依据。

Objective To observe the pathological changes and investigate the hepatocyte apoptosis relating with CYP2E1 in alcoholic liver diseaseof rat. Method the Model of Alcoholic liver Disease: Rats were randomly divided into model group(n=37)and control group(n=33). The dose of 40％ethanol was administerd at 8g/kg body weight by garage twice daily for 8 weeks in model group, and control group was received isovolume saline by gavage. End of 8th week, the activities of serum ALT and AST were detect by autobiochemistry instrument. The pathological changes of liver was observed under light microscope after HE staining, hepatocyte apoptosis was detected by the TUNEL method.

目的： 研究酒精性肝病细胞凋亡程度与细胞色素P4502E1表达的关系方法：用酒精灌胃法制备大鼠酒精性肝病模型，将70只wistar大鼠随机分为正常对照组(33只)和酒精灌胃组(37只)，连续灌胃8周后病理切片观察细胞凋亡程度，干化学法测定ALT、AST的含量变化，用PCR法测定细胞色素P450 2E1的表达变化。

The aim of this study was focused on the cDNAs co-expressed in P35 female and P45 male (sixty-one bands) or expressed only in female at P45, which might play a role in the dimorphic development of RA.

本实验重点研究了P35雌性和P45雄性共表达或P45雌性单独表达的条带(共19条)，推测这些基因片段可能与引起RA核团中的细胞凋亡和性双态性的形成有关。

Eight differential expression bands were cloned and sequenced.Blastn analysis showed that seven of them had highly homology(81%～100%)with EST sequences of Triticum aestivum and Hordeum vulgare.Six of the seven sequences came from Triticum aestivum,and one sequence came from Hordeum vulgare.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
