Background/Aims: The recognition of a correlation between patatin-like phospholipase domain containing-protein 3 (PNPLA3) rs738409 (C>G) and the severity of liver steatosis or fibrosis in chronic hepatitis C (CHC) has not reached a consensus. This meta-analysis sought to investigate with accuracy the association between the PNPLA3 rs738409 (C>G) polymorphism and liver steatosis and advanced fibrosis in CHC patients. Methods: We performed a comprehensive literature search from the PubMed, Embase, Web of Science, and Google Scholar databases up to December 31, 2014. Crude odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. Statistical analyses were performed using Stata 12.0 software. Results: The meta-analysis revealed the severity of liver fibrosis was significantly higher in CHC patients with PNPLA3 rs738409 GG in Caucasians (versus CC+CG: OR, 2.29; 95% CI, 1.57 to 3.35; p<0.05) but not Asian populations. In Caucasians, liver steatosis was also more severe in CHC patients with rs738409 GG (versus CC+CG; OR, 4.33; 95% CI, 2.59 to 7.22; p<0.05). The sensitivity analysis indicated the results of this meta-analysis were stable and no publication bias was detected. Conclusions: PNPLA3 rs738409 (C>G) was associated with the risk of both advanced liver fibrosis and steatosis in patients with CHC, especially among Caucasian populations. (Gut Liver 2016;10:456-463)
BRAIN POTENTIALS OF ONLINE CONTENT EMOTIONALITY ON SOCIAL MEDIA

Introduction Current research investigated whether emotionality of content would facilitate the possibility to share information on social media by using event-related potentials. Theoretical development Emotionality is an excitatory state which evokes autonomic nervous system. Previous studies suggested that stimuli with high emotionality elicited increased P100/P200 amplitudes relative to stimuli with low emotionality (Huang & Luo, 2006). Research design We tested the purpose in an affective priming paradigm in which participants were exposed to online content (i.e. the prime stimulus) followed by a stimulus (i.e. the target stimuli) from International Affective Picture System. Participants were required to judge whether the target was neutral white picture. Next, a nine-point Likert scale was followed to assess the level of emotionality for online content. Result and conclusion We observed a congruency effect in the priming effect. More importantly, early brain potentials P100/P200 were higher when participants were exposed to online content with more possibility to share than online content with less possibility to share. This finding could be explained by the response level account theory (Fazio, 2001). This study provides an insight to neural mechanism underlying emotionality of online content.

Aiming at the triple inverted pendulum which is a strong coupling, multivariable, high-order and unsteady system, a design method of the controller based on PID neural network (PIDNN) optimized by cloud genetic algorithm (CGA) is proposed, this method is called CGA-PIDNN. CGA can be applied to learn and train the PIDNN connection weights. CGA can overcome the defect of the slow convergence rate and premature convergence for genetic algorithm (GA). PIDNN is a simple and normative network which is easy to be realized and has a good dynamic performance. The CGA-PIDNN control system of triple inverted pendulum is verified with MATLAB simulation test. The comparison results with the control effect of PIDNN control system optimized by standard GA (GA-PIDNN) are presented first. Then in LabVIEW environment, by using the combination of virtual reality technology and MATLAB, the three-dimensional (3D) animation simulation model of the triple inverted pendulum CGA-PIDNN control system is built. The simulation results indicate that CGA-PIDNN control method is effective, whose control effects are superior to those by GA-PIDNN control, it is believed that CGAPIDNN is effective and will become a promising candidate of control methods.
