试论宋、元、明真武图像变迁的"一线多元"格局

中国道教的真武图像经历了一个不断变化的过程,特别是宋、元、明三代的变化,真武逐步从武神走向了文神、从地域神走向了全国神.明代武神真武、古圣贤模样的文武神真武、古圣贤模样的文神真武、天帝图真武四种类型,基本概括了宋、元、明真武完成人格化以来所形成的几种基本类型.这种变化表现出一种"一线多元"、多元并存的格局,但真武的披发跣足等基本特征一直保持着相对的稳定性.     

Does Body Image Play a Role in Risky Sexual Behavior and Attitudes?

Body image and sexuality, both physically-oriented domains of the self, are likely linked, but few studies have examined their associations. In the present investigation, we studied emerging adult undergraduates (ages 17–19), focusing specifically on risky sexual behaviors and attitudes. Participants (N=434) completed a survey on body image, lifetime sexual behavior, sexual double standard attitudes, and attitudes about condoms. Males who evaluated their appearance more positively and who were more oriented toward their appearance were more likely to report risky sexual behavior, yet females who evaluated their appearance more positively were less likely to report risky sexual behavior. For most sexual attitudes, patterns did not differ by gender. Individuals who were more oriented toward their appearance believed more in the sexual double standard, and those who had more positive evaluations of their appearance perceived fewer barriers to using condoms. Intervention implications are discussed.An earlier version of this paper was presented at the 2003 Emerging Adulthood Conference, Boston, MA.Doctoral candidate in the Department of Human Development and Family Studies at the Pennsylvania State University.

小鼠心肌细胞核DNA变化与死亡时间的关系

目的监测小鼠死后细胞核DNA降解的情况,探讨死后细胞核DNA降解的一般规律。方法应用单细胞凝胶电泳(SCGE)技术结合荧光显微镜和专业的计算机图像分析技术,测定111只小鼠在死后72h内不同时间点小鼠心肌组织细胞头半径、尾长度、头DNA含量比例、尾DNA含量比例、尾矩、Olive矩、头面积、尾面积八项参数的变化值。结果在个体死亡72h内,测定的八项参数指标均显示细胞核DNA降解速率和程度与死亡时间具有高度的相关性,并获得了更能体现DNA降解趋势的二项式回归方程和多元回归方程,均具有高度的统计学意义。结论应用72h内心肌组织DNA变化与死亡时间之间呈线性关系的各组回归方程,可为法医学推断死后经过时间提供一种新的、客观的、精确的方法和参考依据。     

大鼠博落回总碱中毒心肌细胞凋亡的研究

目的观察博落回总碱中毒后大鼠不同时间内心肌细胞凋亡情况,为博落回总碱中毒提供毒理学指标。方法以SD大鼠博落回总碱中毒为实验模型,通过HE染色及凋亡细胞检测技术对大鼠博落回总碱中毒后心肌病理变化进行研究,并对研究结果进行计算机病理学图像分析。结果大鼠在中毒后的不同时间段内,心肌细胞凋亡数高于正常对照组(P<0.01),且凋亡数在不同时间段差异有显著性。结论博落回总碱中毒在临床症状不明显及毒物分析难以检测的情况下,应用凋亡细胞检测技术可成功检测出心肌的病理学变化。

毒鼠强中毒的凋亡细胞研究

目的通过动物实验,研究观察在不同剂量下毒鼠强中毒后不同时间各器官的病理学变化,以期为法医学鉴定提供指标。方法建立小鼠毒鼠强中毒的实验模型,通过常规H.E染色及凋亡细胞检测技术对小鼠毒鼠强急、慢性中毒后脑、心、肝、肾等器官的病理学改变进行系统研究,并对研究结果进行计算机病理学图像分析;对中毒实验组的小鼠上述器官检材进行毒物分析。结果慢性中毒组小鼠在中毒后的不同时间段内,脑、心、肝、肾等器官凋亡细胞数均高于正常对照组及急性中毒致死组,且同一器官的凋亡细胞数在不同中毒时间段内有所差异,差别均有显著性;不同器官的凋亡细胞数的峰值在不同中毒时间段内亦有所不同。急性中毒组小鼠各器官的毒物分析结果为阳性,慢性中毒组均为阴性。结论慢性毒鼠强中毒,在临床症状不明显及法医毒物分析难以检测的情况下,应用凋亡细胞检测技术可成功检测出机体的主要器官的病理学改变,表明小剂量、慢性中毒对机体仍有一定的影响。

Gender Differences in Peer and Parental Influences: Body Image Disturbance,Self-Worth,and Psychological Functioning in Preadolescent Children

The connections between body image disturbance and psychological functioning have been well established in samples of older adolescent girls and young women. Little is known, however, about body image in younger children. In particular, little is known about possible gender differences in preadolescent children. The current study explored self-reported body image disturbance and psychological functioning in relation to peer and parental influences in 141 elementary school-aged girls and boys aged 8–11. Results suggest that girls are more concerned about dieting and are more preoccupied with their weight than are boys. Girls also reported a greater drive for thinness and a higher level of family history of eating concerns than did boys. Correlations suggested that girls' experiences of body image concerns (body dissatisfaction, bulimia, and drive for thinness) were related to a number of factors (such as family history of eating concerns, peer influences, teasing, depression, and global self-worth) whereas boys' experiences of body image concerns were related to fewer factors. On the basis of these findings, the assessment and treatment of body image concerns in preadolescent children (especially girls) are of great importance. Implications for intervention and prevention programs are discussed.
