回归文本：解读贾宝玉与秦可卿的关系——贾宝玉论之六

秦可卿在整部《红楼梦》中有着不同寻常的结构意义。秦可卿是作者安排的一个核心人物,她的遽然死去是作者安排的一个情节高潮,一个埋葬恶浊丑陋的高潮。在这个高潮中,主人公贾宝玉穿梭其中,并和秦可卿发生了谜一样的关系。贾宝玉和秦可卿关系非同一般,主要有三个情节可以说明,即卧室梦游、探病流泪、闻逝吐血。这三个情节从心理分析的角度可以解释贾宝玉痴情欲绝的原因。也是打开数百年来解读秦可卿、贾宝玉形象谜团的钥匙。从现存的文本考察,秦可卿无疑是宝玉的性启蒙老师。有理由推论,是秦可卿的诱惑使得贾宝玉遽入梦境,在那太虚梦境里,宝玉受到了近乎性虐待的伤害,使他对性产生了恐惧,造成了他心因性的精神阳痿。     

Body mass index and functional status in community dwelling older Turkish males

Abstract

Objectives: To assess sex hormones in men with obesity and prostate cancer (PCa) and to study association between androgens and the pathogenesis biology of PCa in vitro.

Subjects and methods: One hundred and eighty-one men older than 45?years selected from of a population attending to Urology departments screening for PCa, (78 participants without PCa and 103 patients with PCa). All participants were assessed for body mass index (BMI), age, Gleason score, and PSA. Endocrine profile was determined for LH, total testosterone (TT), 17β-estradiol (E2), prolactin and leptin. Biochemical profile (HbA1c, triacylglycerols and lipoproteins) was also determined. In vitro experiments were also performed, involving the study of 5α-dihydrotestosterone (DHT) and E2 in the presence of adipocyte-conditioned medium (aCM).

Results: All variables were continuous and described a Gaussian distribution unless mentioned. To determine the relation of aggressiveness, variable were transformed into categories. Thus, PCa aggressiveness is associated with the increase of age and BMI (p?<?.0001) but with is decreased with TT and E2 (p?<?.05). Moreover, adipocyte-secreted molecules increase aggressiveness of PCa cells in vitro. Lastly, DTH but not E2 enables invasiveness in vitro.

Conclusions: It was observed a coexistence of hormone axis profile alteration with sex hormones and BMI in PCa patients, in accordance with the new perspective of PCa pathogenesis.     

Children's Psychological Response to Parental Victimization

Abstract

This study found that African American children, 6 through 12 years of age, whose parents had been victims of community violence (i.e., gunshot or stabbing) experienced distress symptoms differently, depending on their gender. In the authors' previous work (Dulmus & Wodarski, 2000), children, age 6-12, whose parents were victims of community violence (e.g., gunshot, stabbing), and whose victimization the children did not witness, were found to be experiencing distress symptoms related to their parents' victimization. The purpose of this current study was to do further analysis to examine children's psychological response to parental victimization by gender. Results indicated that all children in the study were experiencing symptoms in the borderline clinical range as measured by the total score on the Child Behavior Checklist (CBCL), with females having a mean score of 39.5 and males having a mean score of 38. The differences that were found by gender were in children's expression of symptoms; with females experiencing more internalizing symptoms (i.e., withdrawn, somatic complaints, anxiety, depression) and males experiencing more externalizing symptoms (i.e., aggression, delinquent behaviors). Such results support feminist theory, which suggests that girls and boys respond differently to stimuli because of gender differences related to socialization. Such distinctions may be clinically useful when choosing approaches to behavioral interventions.     

Childhood poverty dynamics and adulthood overweight/obesity: Unpacking the black box of childhood

Integrating several life course models, this study examines how childhood poverty dynamics shape the risk of adulthood overweight/obesity. Growth mixture models of yearly poverty data from age 0–16 from the U.S. Panel Study of Income Dynamics identify four childhood poverty trajectories: chronic poverty, early childhood poverty, downward mobility, and poverty-free. Chronic poverty and early childhood poverty groups have higher risk of adulthood overweight/obesity than the poverty-free group. Overweight/obesity risk is not significantly different between the chronic poverty group and the early childhood poverty group, suggesting that the effects of early childhood exposure persist despite subsequent upward mobility. Downward mobility in the absence of early childhood poverty does not significantly increase adulthood obesity risk, providing further evidence that early childhood is a critical period for developing risk of overweight and obesity. These findings shed new light on the timing model, social mobility model, cumulative model, and cumulative inequality theory.

Remembering pre-independence childhoods in South India: interrogating autobiographies and identities

This article discusses the potential of autobiography for understanding histories of childhood, the effects of late-colonial social policy and the experience of change in India in the decades immediately preceding independence in 1947. This was an era characterized by both increased state intervention in the lives of poor Indian children and the growing influence of universalizing notions about modern childhood. Based on a detailed study of 55 autobiographies produced by those born between 1910 and 1940, the article analyses the ways in which childhood was imagined, defined and discussed by South Indians through memories that coalesce around the themes of innocence, play, education, work, family and social identity. It demonstrates that these narrations of memory also convey aspirations for contemporary Indian children through comparative reference to the binary of ‘today’ and ‘those days’. The article reveals the complexity of ideas and experiences at a local level which, despite the commonality of age, were refracted through the distinctions of gender, religion, race and class.     

Metabolic Syndrome,Obesity, and Related Risk Factors Among College Men and Women

Abstract

Objectives: The primary objective of this study was to characterize the prevalence of overweight/obesity, metabolic syndrome (MbS) and its criteria, and nutrient intakes of college-age men and women via a large-scale screening. Participants and Methods: From August 2005 to July 2008, 2,722 subjects were recruited for the ongoing, cross-sectional Young Adult Health Risk Screening Initiative project. Anthropometric, biochemical, clinical, and dietary data were collected. Results: Approximately one-half of men and more than one-quarter of women were overweight or obese. MbS was identified in 9.9% of men and 3.0% of women; 77% of men and 54% of women had at least 1 MbS criterion. Intakes of saturated fat, magnesium, and fiber, as well as body mass index and reported physical activity levels were related to MbS. Conclusions: Because of high rates of overweight/obesity and MbS, college-age adults are at risk for developing chronic diseases including diabetes mellitus and cardiovascular disease     

高校硕士研究生体质指数与体质指标的相关研究

My Student Body: Effects of an Internet-Based Prevention Program to Decrease Obesity Among College Students

Abstract

Objective: To determine the impact of My Student Body (MSB)–Nutrition, an Internet-based obesity prevention program for college students. Participants: Three hundred and twenty ethnically diverse undergraduate students were randomly assigned to 1 of 3 conditions: MSB-Nutrition program, an on-campus weight management course, and a comparison group. Methods: Students completed baseline and follow-up surveys regarding their nutrition and physical activity behaviors, self-efficacy, stress, attitudes, and body weight. Results: Compared with the on-campus course and a comparison group, the MSB-Nutrition program increased fruit and vegetable consumption, reduced stress, and increased fruit and vegetable self-efficacy but had no significant effect on students’ exercise self-efficacy, exercise behavior, or weight loss. Conclusions: The MSB-Nutrition program was effective in changing students’ nutrition behaviors but had no effect on physical activity behaviors or weight loss. Suggestions for improving Internet-based interventions aimed at decreasing obesity rates among college students are offered.     

Caffeine intake is not associated with serum testosterone levels in adult men: cross-sectional findings from the NHANES 1999–2004 and 2011–2012

Objective: The association of caffeine intake with testosterone remains unclear. We evaluated the association of caffeine intake with serum testosterone among American men and determined whether this association varied by race/ethnicity and measurements of adiposity.

Methods: Data were analyzed for 2581 men (≥20?years old) who participated in the cycles of the NHANES 1999–2004 and 2011–2012, a cross-sectional study. Testosterone (ng/mL) was measured by immunoassay among men who participated in the morning examination session. We analyzed 24-h dietary recall data to estimate caffeine intake (mg/day). Multivariable weighted linear regression models were conducted.

Results: We identified no linear relationship between caffeine intake and testosterone levels in the total population, but there was a non-linear association (p_nonlinearity?p_nonlinearity?≤?.03 both) and only among men with waist circumference <102?cm and body mass index <25?kg/m² (p_nonlinearity?Conclusion: No linear association was identified between levels of caffeine intake and testosterone in US men, but we observed a non-linear association, including among racial/ethnic groups and measurements of adiposity in this cross-sectional study. These associations are warranted to be investigated in larger prospective studies.
