Abstract： Recently, group emotional contagion has attracted much interest among the scholars of emotional contagion, focusing on the interactive process of emotional contagion among group members. It contains not only direct emotional contagion between two individual, but also the process of group identity, common behavior, collective rules. In addition to inter-individual emotional contagion, group emotional contagion involves two unique emotional outcomes—"emotion cycles" and "collective effervescence". To clarify the occurrence and enhancement process of group emotional contagion, this review associates the three elements of collective ritual (i.e., synchronized actions, shared attention, and shared meaning) and group emotional contagion. Then, the potential mechanisms of collective ritual on group emotional contagion is summarized. First, redundant, repetitive and synchronized actions, as well as shared attention and meaning in collective rituals can trigger the processes related to self-representation. On the one hand, the "self-referential effect" pushes individuals to project personal characteristics into the group, leading to "self-anchoring". On the other hand, collective rituals are characterized by ambiguous causality, but with symbolized social norms embodied. During the process of collective rituals, individuals tend to rely on symbolized social norms to represent themselves, and thus the self-stereotype occurs. As a result, the group identities based on self-anchoring and self-stereotyping is facilitated. Second, strong sense of belonging to the group promotes integrated identity, thereby blurring the boundaries between the individual self and the social self. Highly integrated individuals will experience a transformation of self-representation, from the individual self to the relational self or the collective self (emphasizing group identity), so that an individual will be more closely connected with the group. The group identity generated by collective rituals leads individuals to regard emotion senders as a part of the group and more likely to interpret emotional signals as positive, leading to a larger possibility of emotional mimicry in this context. Emotional imitation under collective ritual produces an emotional experience based on identity, which ultimately enables group emotion to spread on a larger scale. In conclusion, collective rituals enhance group identity through self-stereotyping and self-anchoring. Integrated identity basing on group identity makes individuals pay more attention to group identity, which further leads individuals to transform the individual self into social self and more prone to accepting the group's opinions and emotions. Future studies should further investigate the influencing factors of group emotional contagion and enrich its measurement methods.

Abstract：
"
[Objective] To better understand the occurrence and enhancement mechanism of group emotional contagion, this review analyzed the relationship between the three elements of collective ritual, namely synchronous behavior, shared attention and shared meaning, and group emotional contagion.
[Conclusions] Collective ritual enhanced group identity and further lead to individual transformation of self-representation. Finally, it enhanced the group emotional contagion.
[Limitations]Future research should further investigate the influencing factors of group emotional contagion and enrich its measurement methods.

Abstract： Objective To assess the safety and therapeutic effect of morcellator in transurethral bipolar plasmakinetic anatomical enucleation (TUPKAEP) of benign prostate hyperplasia (BPH). Methods The clinical data of 47 patients with BPH receiving TUPKAEPbetweenJanuaryandJuly,2015wereanalyzed.Duringtheoperation,morcellatorwasusedtosmashtheenucleated BPH which was aspirated with subatmospheric pressure in 29 cases, and the tissue was smashed with bipolar electrosurgical loop slicing from top to bottom and aspirated by ellic suction in 18 cases. Results The procedures were completed successfully inallthe47cases.Thetimeusedforadenomadissociationwas2.24�.09withmorcellatoratthespeedof18.43�.01g/min,and was 17.19�1.74 min with bipolar electrosurgical loop at the speed of 1.91�.65 g/min; the mean total operation time was significantly shorter in morcellator group (28.13�4.71 vs 43.22�5.39 min). The 2 groups showed no significant difference in postoperative continuous bladder irrigation time, postoperative indwelling time of urinarycatheter or postoperativehospital stay.

Abstract： Objective To investigate the antitumor effect of lycorine on renal cell carcinoma ACHN cells and explore the possible mechanism. Methods We used flow cytometry to examine the effect of lycorine on ACHN cell cycle and apoptosis. The cell proliferation, migration and invasion were assessed with MTS assay, wound healing assay, and Transwell assay, respectively. Colony forming assay was performed, and the mRNA and protein levels of Bax, Bcl-2, survivin, caspase-3, cyclin D1 and CDK4 were measured with qRT-PCR and Western blotting. Results Lycorine obviously inhibited the proliferation of ACHN cells with an IC50 of 24.34 μmol/L. Lycorine also induced apoptosis of ACHN cells, caused cell cycle arrest at G0/G1 phase, and suppressed the colony forming ability of the cells in a dose-dependent manner. The migration and invasion of ACHN cells were significantly inhibited by 5 μmol/L lycorine. Lycorine up-regulated the mRNA levels of CDK4, Bax, caspase-3 while down-regulated the levels of survivin, Bcl-2 and Cyclin D1; the protein levels of CDK4 and Bax were increased and cyclin D1, Bcl-2 and surviving expressions were decreased, but caspase-3 expression showed no significant changes following the treatment. Conclusion Lycorine has obvious antitumor effect against ACHN cells, suggesting its value as a new therapeutic agent for renal cell carcinoma.

Abstract： Objective To investigate the effect of stable knockdown of DNA methyltransferase 3b (DNMT3b) on the proliferation and apoptosis of bladder cancer cells. Methods Lentivirus expressing DNMT3b siRNA or the negative control siRNA was infected in human bladder cancer BIU-87 cells. MTT assay and flow cytometry were used to detect cell proliferation and apoptosis, respectively. The inhibitory effect of DNMT3b knockdown on xenograft tumors in nude mice was observed. Real-time PCR and Western blotting were carried out to investigate the expression level of cell apoptosis related genes. Methylation specific PCR was used to examine the methylation in the promoter region of the cell apoptosis related genes. Results The results of real-time PCR and Western blotting showed that DNMT3b mRNA and protein level were stably knocked down in BIU-87 cells. Stable DNMT3b knockdown suppressed BIU-87 cell growth and the tumor formation ability of the cells in nude mice. DNMT3b knockdown promoted the apoptosis of BIU-87 cells, increased the mRNA and protein expression of the cell growth and apoptosis related genes including DAPK, Bax and RASSF1A, and significantly decreased the methylation of these genes. Conclusion Stable DNMT3b knockdown can affect the methylation of the cell growth and apoptosis related genes to regulate their expression, which might be a possible mechanism for suppressed cell growth and enhanced apoptosis of BIU-87 cells.
