Discovery of immune related factors in Fenneropenaeus chinensis by annotation of ESTs

A total of 10446 expressed sequence tags (ESTs) are obtained by a large-scale sequencing of a cDNA library from cephalothorax of adult Fenneropenaeus chinensis. An EST analysis platform was built up based on local computers and bioinformatic techniques were used to annotate these ESTs in order to promptly find possible functional genes, especially for immune related factors. About 4% of the ESTs show similarity to the coding sequences of such factors, including lectin, serine protease, serpin, lysozyme, etc. These ESTs provide a partial profile of the immune system in F. chinensis and useful information for further study on these genes.

成就目标与心理健康的关系及相关因素的作用

The relationship between achievement goal and mental health, and the effect of the related factors Abstract Recently, adolescent’s mental health and depression problem have been widely concerned all over the world. Studies concerning it have been done from different perspectives. High school is the key period of adolescent’s physical and mental development, when they may have a high risk of mental conflicts, certain behavioral and emotional problems. Through questionnaire with high school students as subjects, this study examines achievement goal, self-concept, social comparison and the relationship between these factors and mental health. This study consists of three parts: 1) a preliminary exploration of the relationship between vocational school students’ achievement goal, self-concept and their mental health; 2) a revision of the simplified Chinese version for Dykman’ s goal Orientation Inventory; 3) a further discussion on the relationship between high school students’ achievement goal, self-concept, social comparison and depression. Major findings of this study are: 1. Dykman’s Goal Orientation Inventory is revised. This revised version, with high validity and reliability, conforms to Dykman’s theoretical assumptions and can be a convenient and effective measurement for achievement goal. 2. Self-concept and achievement goal of vocational school students can make a significant prediction of their mental health. Learning goal influences mental health through self-concept. 3. Achievement goal, self-concept and social comparison of high school students are closely related to their depression. 4. Self-concept and social comparison of high school students are the mediator variable between achievement goal and depression. The theoretical and practical implications of this study: 1. With the simplified Chinese version of Dykman’s Goal Orientation Inventory revised and used first in this study, its applicability is inspected and the conclusion drawn by Dykman on the prediction of achievement goal on depression is examined as well; on the basis of previous studies, a comprehensive and systematic study is done on how the factors work together to influence mental health(particularly depression). 2. This study enrichs the studies with high school students as subjects. It provides methods and basis for the theoretical studies and interference about high school students’ mental health education and depression problem.
