Exposure to abnormal light-dark cycles causes depression-like behaviour
and learning deficits in mice. The defects seem to occur independently
of disturbances to sleep and other processes regulated by the biological
clock. See Letter p.594

    ABSTRACT: Jet lag disorder and shift work disorder result from extrinsic work and travel obligations in conflict with the intrinsic circadian rhythm. Poor seasonal or ambient light can prolong the time to adapt to either transmeridian travel or shift work. Symptoms of extrinsic circadian disorders are similar to those of other sleep disorders; namely sleepiness, fatigue, poor or irritable moods, or cognitive inefficiency. Misalignment and the secondary effects are usually temporary and reversed over a period of days to weeks, given sufficient opportunity to recuperate and reentrain.

    ABSTRACT: This study aims to evaluate the efficacy of Xiaoyaosan (XYS) for treatment of major depressive disorder (MDD) and to review the studies on antidepressant mechanisms of XYS. The China Knowledge Resource Integrated Database (1998-2014), VIP Journal Integration Platform (1989-2009), and PubMed (1950-2014) were used to search for and collect scientific publications related to XYS and MDD. Clinical trials for "MDD" and "xiaoyao" were screened. Papers that used the original prescription of XYS for treatment and in combination with Western medicines were included, while papers describing modified XYS were excluded. Four investigators read and screened the resulting publications independently, evaluated the associated scientific results and evidence. There were no conclusive results to support the efficacy of XYS for treatment of MDD, owing to limited sample sizes, flaws in blinding and randomization, and lack of multi-centered clinical trials. Among the experimental studies on the effects of XYS possible involvement of 5-hydroxytryptamine, hypothalamic-pituitary-adrenal axis function, and neuroinflammation were possibly involved demonstrated. The effectiveness of XYS for treatment of MDD is uncertain.
