Effects of environmental stress on the depression-like behaviors and the diurnal rhythm of corticosterone and melatonin in male rats.

Environmental stress (ES) is commonly used in producing chronic unpredictable mild stress to study pathogenesis of depression, including the regulatory role of circadian system on depression. However, the direct effect of ES on the circadian system has been rarely explored. The present study was aimed to investigate the effect of ES on depression-like behaviors and diurnal rhythm of plasma hormone/peptide levels in male rats.

Alterations of the daily rhythms of HPT axis induced by chronic unpredicted mild stress in rats.

The relationship between thyroid function and depression has long been recognized. Patients with thyroid disorders are more prone to develop depressive symptoms and conversely depression may be accompanied by various subtle thyroid abnormalities. However, the daily rhythm alteration of the functions of the hypothalamus pituitary thyroid axis (HPT) is uncertain.

Changes in cropland topsoil organic carbon with different fertilizations under long-term agro-ecosystem experiments across mainland China.

Topsoil soil organic carbon (SOC) data were collected from long-term Chinese agro-ecosystem experiments presented in 76 reports with measurements over 1977 and 2006. The data set comprised 481 observations (135 rice paddies and 346 dry croplands) of SOC under different fertilization schemes at 70 experimental sites (28 rice paddies and 42 dry croplands). The data set covered 16 dominant soil types found in croplands across 23 provinces of mainland China.

[Analysis on neuropsychological characteristics of subtypes of attention deficit hyperactivity disorder].

Objective: To explore the neuropsychological characteristics of children with attention deficit hyperactivity disorder (ADHD).

Methods: Neuropsychological tests, including visual working memory, Stroop test, digits inverse reciting, vocabulary fluency, Wisconsin card sort test (WCST), and Temporal discounting were used to evaluate the capacity of response inhibition, phonological working memory, visual working memory executive function and delayed satisfying capacity of subjects.

[The intelligence characteristics of the head traumatic children].

Objective: To explore characteristics of the head traumatic children's intelligence.

Methods: The authors investigated 43 head trauma children and 50 normal children, using Wechser Intelligence Test (C-WISC). Data were analyzed by SPSS10.
