Background & Objectives: Self-rated health has been widely used to evaluate health status and accepted as a subjective measurement of quality of life. This study aimed to analyze the associations between self-rated health, health promotion behaviors, and mental health factors and suggest the approaches to improve health status among university students. Methods: Two thousand six hundred seventy-seven students who had stayed at dormitories on campus participated in the DU health survey by self-reported questionnaire from April 10 to 14, 2017. Multivariate logistic regression analysis was performed to estimate the odds ratios and 95% confidence intervals of association of self-rated health with health-related factors among male and female students. Results: 38.6% of the respondents reported good self-rated health. Male and first-year students were more likely to report good self-rated health than female and third-year students. There were significant differences in sex, grade, health problems, BMI, sleeping hours, eating breakfast, consumption of fruits and vegetables, physical activity (regular walking, strength exercise, moderate exercise, vigorous exercise), perceived stress, depression, and suicide thought (p<0.05). Conclusion: Although health promotion programs for university students are essential to support their adaptation to campus life and academic achievement, evidence-based health programs to encourage their participation are still insufficient. Therefore, it should establish a campus-based health policy and develop health promotion programs to increase self-rated health levels and prevent mental health problems for university students.

It has now been well documented in a variety of models that T regulatory T cells (Treg cells) play a pivotal role in the maintenance of self-tolerance, T cell homeostasis, tumor, allergy, autoimmunity, allograft transplantation and control of microbial infection. Recently, Treg cell are isolated and can be expanded in vitro and in vivo, and their role is the subject of intensive investigation, particularly on the possible Treg cell therapy for various immune-mediated diseases. A growing body of evidence has demonstrated that Treg cells can prevent or even cure a wide range of diseases, including tumor, allergic and autoimmune diseases, transplant rejection, graft-versus-host disease. Currently, a large body of data in the literature has been emerging and provided evidence that clear understanding of Treg cell work will present definite opportunities for successful Treg cell immunotherapy for the treatment of a broad spectrum of diseases. In this Review, I briefly discuss the biology of Treg cells, and summarize efforts to exploit Treg cell therapy for autoimmune diseases. This article also explores recent observations on pharmaceutical agents that abrogate or enhance the function of Treg cells for manipulation of Treg cells for therapeutic purpose.

Tumor metastasis involves circulating and tumor-initiating capacities of metastatic cancer cells. Hepatic TM4SF5 promotes EMT for malignant growth and migration. Hepatocellular carcinoma (HCC) biomarkers remain unexplored for metastatic potential throughout metastasis. Here, novel TM4SF5/CD44 interaction-mediated self-renewal and circulating tumor cell (CTC) capacities were mechanistically explored. TM4SF5-dependent sphere growth was correlated with $CD133^+$, $CD24^-$, ALDH activity, and a physical association between CD44 and TM4SF5. The TM4SF5/CD44 interaction activated c-Src/STAT3/ Twist1/ B mi1 signaling for spheroid formation, while disturbing the interaction, expression, or activity of any component in this signaling pathway inhibited spheroid formation. In serial xenografts of less than 5,000 cells/injection, TM4SF5-positive tumors exhibited locally-increased CD44 expression, suggesting tumor cell differentiation. TM4SF5-positive cells were identified circulating in blood 4 to 6 weeks after orthotopic liver-injection. Anti-TM4SF reagents blocked their metastasis to distal intestinal organs. Altogether, our results provide evidence that TM4SF5 promotes self-renewal and CTC properties supported by $CD133^+/TM4SF5^+/CD44^+^{(TM4SF5-bound)}/ALDH^+/CD24^-$ markers during HCC metastasis.

Student research has been proposed as an educational strategy to fulfill the current requirements in basic medical education (BME) and to compatible with the self-directed development of professionalism. It is commonly accepted that the goals of student research are to develop the competencies of critical, reflective, and self-directed thinking; problem-solving; and creativity; as well as to acquire the skills necessary to search for information and analyze the literature; to cultivate the talent of mastering a specialized field through deeply intensified learning; and to establish close relationships between students and supervisors. To successfully implement student research, authorities on BME should to plan the procedure for the student research projects and allocate personal and material resources adequately in order to provide the opportunity for self-evaluation and reflection through the completion of daily records, to develop the habit of consistently evaluating one's own study, and to maintain a collegial relationship between students and supervisors by offering the proper feedbacks in a timely and consistent manner. In conclusion, despite several obstacles and difficulties in the establishment of successful student research projects, student research could provide students the motivation to develop themselves into expert academic researchers, and play a role in educating students to help solve patients' problems based on scientific evidence in the future.

The metaverse is emerging as the next digital environment for people not only to interact and collaborate with others, but also to have virtual consumption experiences. In this study, virtual fashion items for the consumer's digital self are deemed significant products with consumption value. Drawing from the regulatory focus theory, this study examines how consumers' promotion and prevention focus influence value perception and buying behaviors of virtual fashion items in the metaverse context. The data were collected through an online survey. A total of 546 consumers in their twenties who are aware of the metaverse responded to a self-administered questionnaire. The results showed that promotion focus influenced all the perceived consumption values of virtual fashion items such as the economic, visual authority, hedonic, and social value, whereas prevention focus influenced only the visual authority value. Visual authority value negatively affected both purchase intention and willingness to pay premium price, while others had a positive effect. The findings provide theoretical evidence that consumers' regulatory focus is critical in buying virtual fashion items and suggest that marketers devise effective strategies to stimulate consumers' regulatory focus and to emphasize the economic, hedonic, and social value of the items in the metaverse context.
