摘要： With the arrival of the 5G era, the live industry is growing rapidly and users are proliferating. Among them, fitness live streaming is in a hot state. In this paper, in order to study the relationship between user interaction behavior and purchase intention between fitness live streaming, a model of the influence of different inter-subject interaction behavior of fitness live streaming on the consumptive desire of live streaming users is proposed by introducing intermediate variables immersion experience and emotional connection. The study conducted a questionnaire survey on 164 live-streaming users who had watched fitness live-streaming. The results show that anchor-user interaction and inter-subject interaction in fitness live streaming positively promote users' immersion experience and emotional connection; users' immersion experience and emotional connection will have a significant positive impact on their purchase intention.

摘要： A PCR-based subtractive hybridization technique was used to identify genes up-regulated in the hibernating bat brain to explore the molecular mechanism of hibernation. Three genes, Liprin-a2, PTP4A2 and CAMKKb were differentially expressed in hibernating bat brain tissue compared to active bat brain tissue. One of them, Liprin-a2, which has recently been shown to have the key function in the organization of presynaptic and postsynaptic multiprotein complexes was studied in detail. We demonstrated that the expression level of Liprin-a2 was up-regulated almost 4-fold in hibernating bat brains by RT-PCR compared to levels in active bats. The differential expression pattern of Liprin-a2 was also detected in muscle, fat, brain and heart tissue of hibernating bats by real-time quantitative PCR. The result indicated that Liprin-a2 was over-expressed in brain and heart tissue and down-regulated in muscle and fat. In brain tissue of hibernating bats, Liprin-a2 expression was statistically significantly higher than in brain tissue of active controls (P = 0.029). The precise control of transcriptional level and the distinctively differential expression pattern of Liprin-a2 in different organs during circannual hibernation may have important physiological significance, not only in maintaining normal function of many key organs but also in effectively conserving limited energy resources without physiological damage.
