Depression is theoretically associated with poor social functioning and social impairments, but empirical evidence for poor trust or cooperative behavior among depressed patients is scarce and severely under-researched. Based on a revised version of Trust Game, the present study aimed to clarify the equivocal relationships between depression, trust and altruistic cooperative behaviors, whilst taking into consideration of the potentially confounding effects of trait propensity to trust and locus of control. In the new version of Trust Game, each pairs of participant played the role of an investor and a trustee respectively. The investor player first receives an endowment of a given amount of money and decides how much he/she would like to invest. The invested endowment is then tripled and given to the trustee, played by the other participant who decides how much repayment he would like to return. This procedure is repeated for 10 rounds, trust behavior and altruistic cooperative behavior are then quantified as the averaged invested endowments and repayments, respectively. Results revealed that depressive symptoms negatively predicted invested endowments (i.e., the trust behavior) after the trait propensity to trust was controlled for, but a positive relationship between depressive symptoms and repayments (i.e., the altruistic cooperative behavior) was found, which was significantly moderated by the external locus of control. Specifically, in those with higher scores in externality, depressive symptoms actually resulted in a decrease (rather than an increase) in altruistic cooperation. This work, for the first time, clarified the relationships between depression and trust and altruistic cooperation by introducing trait factors such as propensity to trust and locus of controls, providing a new sight of exploring the effects of depressive symptoms on social functions.

H1N1 swine influenza A virus (H1N1 SwIV) is one key subtype of influenza viruses with pandemic potential. MicroRNAs (miRNAs) are endogenous small RNA molecules that regulate gene expression. MiRNAs relevant with H1N1 SwIV have rarely been reported. To understand the biological functions of miRNAs during H1N1 SwIV infection, this study profiled differentially expressed (DE) miRNAs in pulmonary alveolar macrophages from piglets during the H1N1 SwIV infection using a deep sequencing approach, which was validated by quantitative real-time PCR. Compared to control group, 70 and 16 DE miRNAs were respectively identified on post-infection day (PID) 4 and PID 7. 56 DE miRNAs were identified between PID 4 and PID 7. Our results suggest that most host miRNAs are down-regulated to defend the H1N1 SwIV infection during the acute phase of swine influenza whereas their expression levels gradually return to normal during the recovery phase to avoid the occurrence of too severe porcine lung damage. In addition, targets of DE miRNAs were also obtained, for which bioinformatics analyses were performed. Our results would be useful for investigating the functions and regulatory mechanisms of miRNAs in human influenza because pig serves as an excellent animal model to study the pathogenesis of human influenza.
