Abstract： Humans are quintessentially social, yet much of cognitive psychology has focused on the individual, in individual settings. The literature on joint action is one of the most prominent exceptions. Joint-action research studies the sociality of our mental representations by examining how the tasks of other people around us affect our own task performance. Executive functions are a family of general-purpose cognitive processes that allow us to regulate cognition. The main executive functions are inhibition, shifting, and updating of working memory. Growing evidence suggests that executive functions can be automatically activated in non-social contexts as well as social ones. It is necessary to test whether people automatically engage in doing the tasks their partners do even when it requires executive functions. The Xibe is one of the ethnic groups in China, mainly inhabits Liaoning, Jilin, and Xinjiang Uygur Autonomous Region. The “westward migration” separated the Xibe in Xinjiang and Northeast China and embarked on different development paths. Xibe living in Xinjiang is in a multilingual culture, which not only retains the Xibe language (part of the Tungus-Manchu group of the Altaic phylum), but also absorbs the language and culture of the surrounding ethnic groups, such as the Uigur and Kazak. While the Northeast Xibe merges with the Han ethnic group and gradually loses their own ethnic culture and language. The present study investigates the influence of multi-language and multi-culture on social cognitive function, using a task-switching paradigm to examine one of the core executive functions, which is switching. In Experiment 1, the classical cognitive switching task was conducted to compare cognitive flexibility between the Xingjiang Xibe and the Northeast Xibe. Participants performed either a parity task (odd or even) or a magnitude task (bigger or smaller than 5), according to the frame around the number (diamond or square). The results showed that Xingjiang Xibe have smaller switch costs in the RT measure and greater accuracy. Experiment 2 employed socially relevant stimuli (faces) to tap into the switching flexibility between 2 types of categories (age and gender) and replicated the cognitive benefits of Xingjiang Xibe. These results showed that Xingjiang Xibe has the switching flexibility advantage in individual setting. Experiment 3 compared the switching flexibility of Xingjiang and Northeast Xibe using task-switching paradigm. A switching task was distributed between two participants. Each participant performed only one of the tasks, and did nothing on the trials of the other. In the social condition, two participants shared a computer. Each performed his task on his trials, and did nothing on the trials of the other participant. In the solo (control) condition, there was only one participant, who passively viewed the stimuli when it was not his turn. There were evident switch costs in the social condition and Xingjiang Xibe showed bigger switch costs compared with the Northeast Xibe, which meant they were more automatically engaged in this joint-action situation. It might be argued that, in the social condition, participants were distracted by the presence of a partner, or that they were sometimes uncertain about whose turn it was, and these factors lowered their efficiency. These costs are referred as turn-taking costs. In order to address this issue, Experiment 4 isolated turn-taking costs from task-switching costs by adding a condition in which two participants took turns, but they performed an identical task. This condition didn’t result in switch costs, indicating that costs in Experiment 3 should be interpreted as switching costs. Experiment 5 applied eye test to further prove that Xingjiang Xibe had strong individual tendency to understand the others’ intentions. In summary, the results showed that multilingualism and multiculturalism have different effects on cognitive switching function, positive effect in individual context and negative effect in social context. The results of this study provide important inspiration for the construction of a multi-ethnic country.

Abstract： This paper summarized the nursing measures for four patients with acute pancreatitis after lower extremity endovascular intervention, and provided a reference for the postoperative nursing of vascular intervention surgery. Key issues of nursing included psychological care, preoperative hydration, guidance of dietary, observation of illness condition, prevention of complications, nutrition support and medication care. There are two severe cases of acute pancreatitis, one of which eventually died due to multiple organ failure, and the other was cured after drug treatment. In addition, two mild cases of acute pancreatitis, which were cured after drug treatment. As rare angiographic complication, acute pancreatitis is not easy to be detected early. The possibility of acute pancreatitis must be considered when a patient presents with abdominal pain, elevated creatinine, or multiple organ failure following an interventional procedure. Early detection and diagnosis, and timely treatment are beneficial to improve the cure rate of postoperative complications.

Abstract： Several components in phonogram characters, such as ‘女’, ‘口’ and ‘马’, can be phonetic radical in the phonetic components’ location or semantic radical in the semantic components’ location. We call these components Chinese wordable components (or Chinese wordable radical), and such components must be a single Chinese character. The location and function of Chinese wordable components vary in Chinese characters. In theory, each wordable components can appear in different parts of Chinese characters. However, the same component appears in different locations of Chinese characters with different characterisation characteristics because of the assumption that the location of components follows orthographic rules, and the frequency of the components’ location is different. However, previous studies have failed to distinguish between components’ location and the frequency of components in various locations and did not explore the effects of wordable components in different locations.This study used the component priming paradigm, which can effectively explore the effect of components’ location on the cognition of Chinese characters. With regard to components that can appear in different locations of Chinese characters, this study investigated the roles of different parts in Chinese character recognition by matching the usage frequency of Chinese characters (all high-frequency characters), stroke numbers and other factors in the component priming paradigm. Experiment 1 adopted the component priming paradigm to investigate the function of wordable components in different locations in Chinese character recognition. The priming stimuli were wordable components of three locations (primary semantic radical, secondary semantic radical and phonetic radical). The target stimuli were Chinese characters that contained these wordable components in three locations. Subjects were asked to identify the true and false characters of the target Chinese characters. Experiment 2 adopted component priming and visual search paradigms to investigate the function of wordable components in different locations. The priming stimuli were similar to those in Experiment 1. The target stimuli were square pictures that contained four Chinese characters. Subjects were asked to determine the presence of true and false characters in the picture, and eye movement data were recorded.The following points were gathered from the results. Firstly, the priming effect of the wordable component in the phonetic radical’s location was stronger than that in the semantic radical’s location. Secondly, when the wordable components were applied as semantic radical, they only appeared in the primary semantic radical’s location rather than in the secondary semantic radical’s location. Lastly, the wordable components in the phonetic radical’s location promoted not only the cognition of Chinese characters containing the phonetic radical’s location components but also the cognition of Chinese characters containing the primary semantic radical’s location components. However, they hindered the cognition of Chinese characters containing the secondary semantic radical’s location components. When priming components appeared in the secondary semantic radical’s location, they had no effect on the Chinese characters containing related components.The study showed that in Chinese character cognition, the effect of component location includes the dual effect of the components’ location and the frequency of the components’ location.

Abstract： Colorectal cancer (CRC) is one of the most common tumors in the world. Colorectal polyps are local protuberant lesions higher than the intestinal mucosa, and about 90% of CRC is evolved from polyp. According to the traditional concept, the occurrence and development of CRC is mostly through the "adenoma-cancer" sequence. However, studies have found that serrated polyps also form subclasses with different morphology and genes, and are closely related to microsatellite unstable CRC. About 15%~30% of CRC develops through the "serrated polyp-cancer" pathway. This article mainly reviews the clinical characteristics of colorectal adenoma, serrated polyp and post-inflammatory polyps, through retrospective analysis of large samples, to summarize the incidence of different pathological types of colorectal polyps in the progression of carcinogenesis and the follow-up monitoring after polypectomy,so as to provide a better reference for follow-up monitoring of polyp patients and early screening and early treatment of precancerous lesions.

Abstract： The term meta-stereotype refers to the beliefs of in-group members regarding the stereotypes that out-group members hold about them. Its valence can be positive or negative, and its effects can also be positive or negative. Previous researchers have held the view that the valence and effects of meta-stereotype conform to the “rewarding principle.” In other words, positive meta-stereotype activation would have a positive effect, and negative meta-stereotype activation would have a negative effect. However, recent studies, have found that this relationship was not consistent. Up to now, the nature of the relationship between the valence and effects of meta-stereotype is still a matter of debate. For the negative meta-stereotype activation, its threat effect conforms to the rewarding principle, whereas the reactance effect does not. The threat effect of the negative meta-stereotype is that its activation could result in psychological conflict for individuals engaged in social situations. This may induce them to face a loss of cognitive balance and experience anxiety and stress, resulting in negative consequences. In contrast, it is possible for the activation of negative meta-stereotype to have a positive effect, that is, the reactance effect. When the negative meta-stereotype is activated, individuals perceive that they are being negatively evaluated by the out-group members. They may act to refute the negative evaluation. They would then display positive behaviors in a way to maintain a positive in-group image or prove their own abilities. It was found that the threat and reactance effects of negative meta-stereotype differ in the research scope, mechanism, and interventions that would eliminate the negative effects of meta-stereotype. For the positive meta-stereotype activation, its boost effect conforms to the rewarding principle, whereas the choking effect does not. In general, the positive meta-stereotype reflects the positive evaluation by the out-group to the in-group members; that is, it contains a number of positive characteristics. Therefore, the activation of the positive meta-stereotype can lead to a boost effect. Specifically, when individuals feel that they are positively viewed by the out-group members, they not only feel better about themselves, but also are encouraged to give back to other out-group members in helpful, constructive way. In contrast, positive meta-stereotype activation may also have a negative effect; that is, the choking effect. If individuals perceive that the out-group members hold very high expectations of them, they may feel substantially more pressure. This can bring about undesirable outcomes. They might focus too intensely on themselves, or even feel worry and doubt their own abilities, and subsequently perform badly. After comparing previous studies of the boost and choking effects of positive meta-stereotype, it was found that the differences between them were in the research scope, mechanism, and the mode of activation. Based on the analysis of the four effects mentioned above, it appears that the effects of meta-stereotype activation of different valences are influenced by a variety of factors at the individual and the group levels. Among them, the individual-level factors are the difficulty of retrieving the meta-stereotype, the internal resources, the degree of meta-stereotype personalization, and the impression management motivation; the group-level factors include group social status. Although research on meta-stereotype has gradually expanded, it still mainly focuses on the threat effect of the negative meta-stereotype and the boost effect of the positive meta-stereotype respectively. Studies on the reactance effect of the negative meta-stereotype and the choking effect of the positive meta-stereotype are limited. Many issues remain to be addressed. Future research can further expand the fields and preconditions of the diverse effects activated by the negative and positive meta-stereotypes, explore the interventions to eliminate the negative effects of meta-stereotype, and investigate the role of meta-stereotype activation mode.

Abstract： " Considerable research suggests that musical experience and ability are related to various cognitive abilities. One aspect of cognition that may be related to musical training is executive function (EF), which involves a set of top-down processes that regulate behavior and cognition according to task demands. To date, many studies are investigating this relationship. However, results are mixed and difficult to compare because of not only the variety of EF components examined but also the variety of tasks used to measure EF and the variety of criteria used to categorize participants as “musicians” or “non-musicians.” Moreover, most studies focus more on Western music than Chinese folk music, which has its own unique expression and distinct musical character. Dong Chorus, which is the multipart folk chorus of the Dong people in Guizhou Province, holds an important and unusual position in Chinese polyphonic folk songs. This stature is due to their splendid artistry, long history that can be textually researched, and the great influence of their vivid artistic practice, which gained the favor of numerous musicians. However, only a few scholars have studied the folk songs from the perspective of cognitive psychology or by means of experiments. In this study, we divide EFs into three core components: inhibitory control, working memory, and cognitive flexibility in auditory and visual modalities. Dong musicians (n=32), Dong non-musicians (n=32), and the Han (n=32) high school students were involved in six experiments to test the effect of Dong Chorus on cognition and the existence and generality of the relationship between musical ability and EFs. Results showed that Dong musicians and non-musicians outperformed Han students in inhibitory control and memory updating in auditory and visual versions of EF tasks, but no significant difference existed among the three groups in terms of shifting, which proved the generality of cognitive advantages of Dong Chorus. Dong non-musicians outperformed Han students in inhibition and switching, which suggested the interaction between language and music. In summary, these results indicated that cognitive advantages associated with Dong Chorus are not limited to auditory processes, but they are limited to specific aspects of EF. This finding supports a process-specific (but modality-general) relationship between musical ability and nonmusical aspects of cognition. Protecting and developing the Dong Chorus are important.
