人群中甲状腺结节发病率很高,多数均为良性病变,但需要结合病史、临床症状、体征、甲状腺功能检查、超声及甲状腺细针抽吸细胞学(FNAC)检查,以排除恶性肿瘤。针对无恶性征象的甲状腺结节患者可以定期随访,必要时行外科手术治疗。 相似文献

Psychopathy is a disorder that occurs primarily in males. Offenders with psychopathic traits are responsible for a disproportionate amount of crime in society, particularly violent crime. Early childhood is a time when individual differences in empathy and guilt—key indicators of the construct of psychopathy—are first evident. A growing number of longitudinal studies have begun to investigate how factors in infancy and early childhood predict psychopathic-like traits in later childhood, adolescence, and adulthood. These studies have suggested that parenting styles during infancy (parental sensitivity, maternal harsh intrusion, commenting on the emotional state of the child) as well as attachment styles are predictive of later psychopathic-like traits. In addition, child characteristics such as temperament and the functioning of biological systems such as the autonomic nervous system and hypothalamic–pituitary–adrenal axis are predictive. Overall, studies have suggested that at least some of the origins of psychopathic traits are present in infancy and early childhood, which is consistent with the perspective of psychopathy as a neurodevelopmental disorder. A recent evolutionary-developmental model provides hypotheses regarding how psychopathy may develop and why it is more common in males than females. This model, and its implications for intervention, is discussed in the context of the longitudinal studies that have been conducted on psychopathy. 相似文献

Gender-dependent differentiation of the brain at morphological, neurochemical and functional levels of organization have been shown to be primarily controlled by sex differences in gonadal hormone concentrations during pre- and early postnatal development. Indeed, previous studies have reported that pre- and perinatal hormonal environments influence brain development and, consequently, affect sex specific long-term language outcomes.Herein, we investigated whether postnatal surges of estrogen (estradiol) and androgen (testosterone) may predict properties of pre-speech babbling at five months. This study is the first attempt to investigate a possible correlation between sex hormones and infants’ articulatory skills during the typical postnatal period of extended hormonal activity known as ‘mini-puberty.’ A hierarchical, multiple regression approach revealed a significant, robust positive relationship between 4-week concentrations of estradiol and individual articulatory skills. In contrast, testosterone concentrations at five months negatively correlated with articulatory skills at the same age in both boys and girls. Our findings reinforce the assumption of the importance of sex hormones for auditory–vocal development towards language in human infants. 相似文献
