Abstract	This article studies the problem of finite-time stability (FTS) and finite-time contractive stability (FTCS) for nonlinear impulsive systems, where the possibility of time delay in impulses is fully considered. Some sufficient conditions for FTS/FTCS are constructed in the framework of Lyapunov function methods. A relationship between impulsive frequency and the time delay existing in impulses is established to reveal FTS/FTCS performance. As an application, we apply the theoretical results to finite-time state estimation of neural networks, including time-varying neural networks and switched neural networks. Finally, two illustrated examples are given to show the effectiveness and distinctiveness of the proposed delay-dependent impulsive schemes.

Abstract	Aims: The aims for this study was to prove the impacts of marital events (marriage rate, divorce rate and marriage squeeze), economic development, and social development on the suicide rate among urban and rural Chinese and reveal the differences in these impacts between urban and rural areas and between genders. Methods: An explanatory time-series analysis methodology was adopted to analyze the nation-wide data ranging from 1987-2017. Results: Marriage rate was a protective factor against the suicide rate among urban and rural men, and rural women; however, divorce rate was a protective factor against the suicide rate only among rural women. For the four groups, the economic development level measured by per capita GDP is a protective factor, while social development measured by urbanization and rural-urban labor migration rates in rural areas plays different roles. Conclusions: Marriage and divorce rates were found to have different meanings for the four groups. This study offers a reference for designing relevant policies and projects to intervene in suicidal behaviors among different groups.

Abstract	Higher sex ratio at birth often leads to sex imbalance and a severe squeeze on the marriage market. Up to now, no systematic studies have examined the relationship between marriage squeeze and suicidal ideation among rural men in a context of sex imbalance. Using surveys conducted in Chaohu (Anhui Province) and Ankang (Shaanxi Province) in China, this study analyzed the impact of marriage squeeze and social support on suicidal ideation among rural men. The perceived marriage squeeze significantly and positively affected suicidal ideation and the perceived social support negatively affected suicidal ideation among married and unmarried rural men. Objective social support did not significantly affect suicidal ideation among married men; however, it negatively affected suicidal ideation among unmarried men. Marriage squeeze increased the incidence of suicidal ideation among rural men, but perceived social support acted as a protective factor against suicidal ideation. These findings support the main effect hypothesis of social support. Objective social support is a double-edged sword, which may increase suicidal ideation incidence among rural men. The article ends with the conclusions and limitations of this study.

Abstract	Objective: This article aims to explore the potential categories of college students' sports behavior motivation and the differences between different family social classes on potential categories. Participants: In total, 1,092 college students were investigated in this study. Methods: This article used the "College Students' Sports Behavior Motivation Questionnaire" to survey 1,092 college students using the whole group sampling method. The potential profile analysis method was applied to classify the types of college students' sports behavior motivation and further analyze the characteristics of different family social classes and sports behavior motivation. Results: College students' sports behavior motivation types can be divided into the following four categories: "low motivation type" (0.82%), "healthy appearance type" (11.45%), "healthy fun type" (37.36%), and "high motivation type" (50.37%). The higher the family's social class, the more the sports behavior motivation of college students tends to be healthy appearance, health, fun, and high motivation. The lower the family social class, the more motivational sports behavior of college students tends to be low motivation. The better the perception of health, the higher the probability that college students belong to the high-motivation type. The fewer chronic diseases that college students have are associated with a healthy appearance and high motivation. Conclusion: There is a certain relationship between the type of college students' sports behavior motivation and their family social class. Therefore, in school physical education, we should open all kinds of sports activities according to college students' sports behavior motivation needs and focus on college students with lower family social class in order to intervene precisely on their motivation for sports behaviors, improve participation, and promote the overall health of college students.

Abstract	Since the COVID-19 pandemic, the use of mobile health apps has been increasing significantly. Many have started using mobile health apps to manage their health and well-being. People need to develop healthy habits that will increase their job productivity, life expectancy and improve their social relationships. This study tests the Health Belief Model with adults in China in influencing health motivation and in turn improving their health behavior. A mobile and online survey was developed, and 120 usable responses were collected. A structural equation modeling was used to test the relationships between perceived benefits, perceived susceptibility, perceived barriers, health motivation, and health behavior. We found perceived self-efficacy, perceived benefits, and perceived susceptibility predicts health motivation, and health motivation predicts health behavior. We did not find that perceived barrier is a predictor for health motivation. We conclude that to encourage behavioral change, it is important to enhance self-efficacy and address the benefits; in the meantime, educating people on susceptibility is also important.

Abstract	Interleukin (IL)-22 regulates host defense. This study investigated the predominant IL-22-producing cell subsets under HBV associated immune stages. We found circulating IL-22-producing CD3 + CD8- T cells were significantly increased in immune active (IA) stage than those in immunotolerant stage, inactive carrier and healthy controls (HCs). The plasma IL-22 level was higher in IA and HBeAg-negative CHB compared to HCs. Importantly, CD3 + CD8- T cells were identified as the predominant source of plasma IL-22 production. Up-regulated IL-22-producing CD3 + CD8- T cells obviously correlated with the grade of intrahepatic inflammation. The proportions of IL-22-producing CD3 + CD8- T cells were significantly down-regulated after 48 weeks of Peg-interferon treatment, and the differences were of great significance in patients with normalize ALT levels at 48 weeks, rather than those with elevated ALT levels. In conclusion, IL-22 might play a proinflammatory function in. chronic HBV infected patients with active inflammation and Peg-interferon treatment could attenuate the degree of liver inflammation through down-regulating IL-22-producing CD3 + CD8- T cells.

Abstract	Objective: In the context of Healthy China, the effect of external motivation on sports anomie behavior from the perspective of gender among Chinese college students was investigated. Participants: In total, 2,340 college students were involved in this study. Methods: The self-made scales were used, which were about anomie behavior and external motivation in sports. The independent sample Results: Girls' sports anomie behavior was lower than boys. There were significant gender differences in honor motivation, obedience motivation, and economic motivation; girls' motivations were lower than boys. The academic motivation was negatively correlated with the sports anomie behavior of college students of both genders. The economic motivation was positively correlated with their sports anomie behavior. The honor motivation was negatively correlated with the sports anomie behavior of female college students. Conclusion: Female college students' sports anomie behavior and external motivation are lower than that of male college students. External motivation had a significant influence on college students' sports anomie behavior.

Abstract	Background: Suicidal ideation was proved to be a critical precondition leading to the occurrence of subsequent suicidal behavior. Studies have confirmed that negative life events and forms of social support that youth are experiencing in the current socio-cultural context might have unique impacts on their suicidal ideation. However, the specific mechanism is relatively underexplored. Objective: We sought to investigate the impacts of offline and online social supports on Chinese students' suicidal ideation under the pressure of various negative life events, as well as potential gender differences in these relationships. Methods: Participants were 2,018 middle - high school and university students from Northwestern China, who completed a demographics questionnaire and self-report measures of negative life events, social support, and suicidal ideation. Results: Offline social support had a significant direct effect on suicidal ideation across genders. Among male youth, offline social support only had a moderating effect on the relationship between punitive negative life events and suicidal ideation. Among female youth, offline social support had a significant moderating effect on suicidal ideation under the pressure of all types of negative life events; Online social support only had a significant direct effect on female youth's suicidal ideation, although it did significantly moderate the relationship between all types of negative life events and suicidal ideation, across genders. Conclusion: Our findings revealed direct and moderating effects of offline and online social support on suicidal ideation among youth under the pressure of different types of negative life events, as well as gender-specific patterns in these relationships.

Abstract	In the framework of impulsive control, this article deals with the lag synchronization problem of neural networks involving partially unmeasurable states, where the time delay in impulses is fully addressed. Since the complexity of external environment and uncertainty of networks, which may lead to a result that the information of partial states is unmeasurable, the key problem for lag synchronization control is how to utilize the information of measurable states to design suitable impulsive control. By using linear matrix inequality (LMI) and transition matrix method coupled with dimension expansion technique, some sufficient conditions are derived to guarantee lag synchronization, where the requirement for information of all states is needless. Moreover, our proposed conditions not only allow the existence of unmeasurable states but also reduce the restrictions on the number of measurable states, which shows the generality of our results and wide-application in practice. Finally, two illustrative examples and their numerical simulations are presented to demonstrate the effectiveness of main results.
