高校高水平足球运动员攻击行为社会认知研究

采用内隐社会认知的实验方法,结合足球比赛的场景,以高校高水平足球运动员为实验组,高校体育学院足球专选学生为对照组,进行了再认和偏好测验。结果显示,高校高水平足球运动员具有内隐攻击性,不同性别,不同技能水平的足球运动员之间在攻击的外显认知上存在较大差异,但内隐认知上几乎不存在差异。

Thyroid disorders in women of Puducherry

Thyroid stimulating hormone (TSH), Free Thyroxine (FT₄) and Free Triiodothyronine (FT₃) were assayed in 505 women of this region. 60 women had previous history of thyroid disease. The remaining 445 women formed the “Disease free group”. A “Reference group” was obtained by excluding women with previous and present history of thyroid dysfunction. Of the total 505 women examined 15.8% had thyroid dysfunction and 84.2% were euthyroid. 11.5% were hypothyroid (9.5% sub-clinical) and 1.8% hyperthyroid (1.2% clinical). The geometric mean TSH for the total population was 2.65 μIU/ml. It was significantly (p=0.025) lower in the reference population 2.17 μIU/ml. There was no significant difference in the FT₃ and FT₄ values between groups. 19% of women over 60 years had elevated TSH above 4.5 μIU/ml. The 2.5 and 97.5 percentiles of the reference population was 1.1–5.2 μIU/ml. 6.1% of women in the reference group had TSH levels above the reference intervals. Hypothyroidism particularly sub-clinical hypothyroidism is predominantly present amongst women in this iodine sufficient region. Evaluation of thyroid status could help in early detection and treatment.     

经手术切除甲状腺和嗅球的大鼠有可能成为一种难治性抑郁症的实验动物模型

目的：探讨建立伴有甲状腺功能低下的难治性抑郁症实验动物模型的可行性。方法：将30只雄性SD大鼠随机分成3组,每组10只：模型组、假手术组、正常对照组。模型组大鼠首先接受甲状腺切除术,7天后再次接受双侧嗅球切除术;对假手术组大鼠除了不切除甲状腺与双侧嗅球以外,其余操作均与模型组的完全相同;对正常对照组大鼠则不进行任何处理。在最终手术后的第2周,采用旷场试验、强迫游泳试验与Morris水迷宫测试各组大鼠的行为变化。结果：与正常对照组或假手术组大鼠相比较,模型组大鼠长生相对停滞、体重明显减轻,并出现焦虑样和抑郁样行为,空间学习记忆能力明显下降。模型组大鼠的这些指标与正常对照组或假手术组大鼠的差异均有统计学意义（P＜0.01）,但正常对照组与假手术组之间的差异则无统计学意义（P＞0.05）。结论：本研究全程应用两种外科手术建立的大鼠模型在原因与行为变化方面,可较好地模拟出伴有甲状腺功能低下的难治性抑郁症的临床特征,故其可能有潜力成为这类难治性抑郁症激越亚型的一种实验动物模型,也为后续开展联合药物治疗与揭示相关药理学机制的研究打下了一个平台。
