Objective To discuss the effects of health management model on mental health of undergraduates. Methods A total of 2244 freshmen from a college were randomly assigned to the study group (n =824) and the control group (n = 1420) in 2009. Chinese College Students Mental Health Scale (CCSMHS) was used to investigate the changes of the participants in the study group after receiving the health management and analyze psychological differences between 2 groups. Results In CCSMHS,all P was found to be less than 0. 05, except for anxiety ( t = 1.90, P = 0. 058 ), reliance ( t = 1.27, P = 0. 206), and impulse (t = -0. 60, P = 0. 551 ). In 8 dimensionalities with significant differences, scores were decreased after health management when compared with baselines. Instead of body ( t = - 1.38, P = 0. 168 ), all the other scores showed statistically significant differences between the 2 groups. Conclusion Mental health of those who received health management was better than those who didn't. However, anxiety, reliant, and impulse did not improve as a result of shorter intervention time, and the challenge facing psychology intervenion.

Objective To understand the effect of health management to enhance the community hypertensive patients' self-efficacy. Method With the method of stratified random sampling, 347 patients who come from communities were diagnosed as hypertension were selected as research subjects from the range of Yingze in Taiyuan of Shanxi province. There were 191 males and 156 females, the age ranged from 38 to 72 (55.90±9.60) years. The self efficacy promotion plan was conducted on high blood pressure patients. A comparison before and after six months of health management was made among the self efficacy scores, daily life scores, health behavior scores, drug behavior scores, medical compliance behavior scores by using self-efficacy scale. Excel 2007 and SPSS 19.0 were used for data analyses. Result Before the implementation of health management, the self efficacy scores of research subjects were 26.96 ± 0.77. After the implementation of health management, the value increased to 29.51 ± 0.86 (t=-41.23, P<0.05). In four dimensions, daily life (before and after management 6.85 ± 0.20 and 7.49 ± 0.31, t=-40.66), drug behaviors (before and after management 7.52 ± 0.21 vs. 7.98 ± 0.23, t=-26.93) and medical compliance behavior scores (before and after management 5.26±0.15 vs. 6.78±0.19, t=-115.97) were higher than those before the health management except health behaviors (before and after management 7.25 ± 0.40 vs. 7.26 ± 0.40, t=-1.94, P<0.05). Conclusion Health management regulated the self care behavior of patients with hypertension, improved the patients' compliance and enhanced self efficacy, which played an important role in controlling the development of disease.

Objective To understand the quality of sleeping in medical students, and provide a reference basis for designing sleep health management program for college students. Methods The survey was conducted at a medical college in Shanxi province with stratified random sampling and Pittsburgh Sleep Quality Index (PSQI) scale. Totally 210 individuals were enrolled, 199 completed the questionnaire, with a response rate of 93.5%. SPSS 21.0 statistical software was used for data analysis. Descriptive statistical analysis was carried out for socio-demographic data. Independent t-test, one-way analysis of variance and non-parametric test were used to compare the scores of PSQI between participants. Multiple stepwise linear regression was used to determine influencing factors of sleep quality. Results The average score of PSQI for the 199 medical students interviewed was (6.74±2.42), the incidence of sleep disorder was 50.25%, the overall sleep quality was not high. Learning pressure of medical student had statistically significant in PSQI (Completely unmatched, 5.14 ± 2.32, Mostly unmatched, 5.93 ± 2.73, Mostly matched, 6.70 ± 2.42, Absolutely matched, 7.39 ± 2.10, F=3.366, P=0.020), employment pressure of medical students in PSQI (Completely unmatched, 6.50 ± 0.71, Mostly unmatched, 6.80 ± 3.24, Mostly matched, 5.98 ± 2.14, Absolutely matched, 7.14 ± 2.35, F=3.134, P=0.027). Grade (β=-0.172, P<0.05) and learning pressure (β=0.210, P<0.01) were the main influence factors for students. Conclusion Sleep quality of medical students was not high, upper grade was worse than low grade, the incidence of sleep disorder had increasing trend as learning pressure and degree of employment pressure worsen.

Objective: To explore the relationships among perceived stress, emotion regulation strategies, and abnormal eating behavior among medical students, in order to provide healthy eating behavior reference for medical students, especially under pressure. Methods: Chinese Perceived Stress Questionnaire, Emotion Regulation Questionnaire, and Dutch Eating Behavior Questionnaire were administered among 777 students from three medical universities in Shanxi seleceted by a stratified random cluster sampling method. Results: There were significant differences in unhealthy eating behavior by gender and major. Abnormal eating problem score of clinical medicine students was significantly higher than that of non-clinical medicine students (t=3.56,P<0.01); Scores of restrained eating behavior, emotional eating behavior, and exogenic eating behavior of clinical medicine students were all significantly higher than those of non-clinical medicine students (t=3.45, 3.04, 4.19, P<0.01). Abnormal eating behavior, and restrained eating behavior and exogenic eating behavior in female students were significantly higher than those of male students (t=2.28, 2.58, 2.46, P<0.05). The perceived stress significantly and positively correlated with the abnormal eating behavior (P<0.01); Cognitive reappraisal and expressive inhibition significantly and negatively correlated with abnormal eating behavior respectively (P<0.01); No significant association was found between expressive inhibition and abnormal eating behavior. Cognitive reappraisal mediated the association between abnormal eating behavior with perceived stress which accounted for 36.89%, mediating effect in boys was higher than that of girls. However, expressive inhibition showed no similar effect and gender difference. Conclusion Perceived stress can influence abnormal eating behavior of medical students through cognitive reappraisal directly or indirectly, while expressive inhibition shows no such mediating effect. For medical students under pressure, the skill of emotion regulation through cognitive reappraisal, emotion expression as well as appropriate coping style under pressure should be developed.

Objective: To present the evolutionary path of Chinese Medical Ethics, analyze the development vein of periodical, explore the journal' s research focuses, and provide reference for related personnel to understand the development of the current research status in the field through visualization technology. Methods:Using biblio-metric method,taking "China National Knowledge Infrastructure" as source of data collection, we used the visual-ization software CiteSpace to draw scientific knowledge maps and analyzed literatures published from 1990 to 2014 in Chinese Medical Ethics. Results:The annualvolume of journal articles fluctuated upwards,with peaks in 1992, 2000 and 2009, and of which the most was in 2009, with 393 articles. "Medical Ethics" and "Doctor-patient Relationship" were hotwords in this field. The publications of domestic and foreign scholars promoted the interna-tional exchange and the development of Chinese medical ethics, and the most productive institutions were often col-leges or universities. Conclusion:Chinese Medical Ethics has effectively promoted the development of bioethics in China, more and more scholars are involved in the relative research of medical ethics, and the old, middle and young scientists and research teams inherit, cooperate and develop with each other. The cross-regional, inter-a-gency and interdisciplinary collaboration remains very limited, whichwill become the important factorinfluencingthe development of the field of Chinese medical ethics in the future.

Objective: To understand the knowledge and behavior towards COVID-19 among primary and middle school students in Guangdong province, so as to provide basis for health education on epidemic prevention and control. Methods: An online questionnaire survey was conducted among 1 222 403 primary and middle school students in Guangdong Province from March 8 to 31, 2020. Results: In Guangdong Province, 96.28%, 80.01% and 38.58% of primary and middle school students knew the transmission route of the novel coronavirus was droplet transmission, contact transmission and aerosol transmission respectively, and 78.22% of the students knew the two main transmission routes. Among COVID-19 prevention and control measures, the top three well-known measures were mask wearing(99.69%), frequent hand washing(99.06%) and social distancing(96.21%). During the pandemic, 88.48% of students wore masks every time they went out, 32.15% reported that they needed parental supervision, and 53.97% reported they would continue wearing masks after the pandemic. 87.21% of students washed their hands every time after going out, 18.78% reported that they needed parental supervision, and 94.92% reported that they would continue washing their hands frequently after the pandemic. Conclusion Primary and middle school students in Guangdong Province had high rates of awareness on transmission route and prevention and control measures of COVID-19. During the pandemic, the rates of wearing masks or washing hands every time after going out was high, and the rates of behavior intention of washing hands after the pandemic was high.

Background::DOK3 (Downstream of kinase 3) is involved primarily with immune cell infiltration. Recent research reported the role of DOK3 in tumor progression, with opposite effects in lung cancer and gliomas; however, its role in prostate cancer (PCa) remains elusive. This study aimed to explore the role of DOK3 in PCa and to determine the mechanisms involved.Methods::To investigate the functions and mechanisms of DOK3 in PCa, we performed bioinformatic and biofunctional analyses. Samples from patients with PCa were collected from West China Hospital, and 46 were selected for the final correlation analysis. A lentivirus-based short hairpin ribonucleic acid (shRNA) carrier was established for silencing DOK3. A series of experiments involving the cell counting kit-8, bromodeoxyuridine, and flow cytometry assays were performed to identify cell proliferation and apoptosis. Changes in biomarkers from the nuclear factor kappa B (NF-κB) signaling pathway were detected to verify the relationship between DOK3 and the NF-κB pathway. A subcutaneous xenograft mouse model was performed to examine phenotypes after knocking down DOK3 in vivo. Rescue experiments with DOK3 knockdown and NF-κB pathway activation were designed to verify regulating effects. Results::DOK3 was up-regulated in PCa cell lines and tissues. In addition, a high level of DOK3 was predictive of higher pathological stages and worse prognoses. Similar results were observed with PCa patient samples. After silencing DOK3 in PCa cell lines 22RV1 and PC3, cell proliferation was significantly inhibited while apoptosis was promoted. Gene set enrichment analysis revealed that DOK3 function was enriched in the NF-κB pathway. Mechanism experiments determined that knockdown of DOK3 suppressed activation of the NF-κB pathway, increased the expressions of B-cell lymphoma-2 like 11 (BIM) and B-cell lymphoma-2 associated X (BAX), and decreased the expression of phosphorylated-P65 and X-linked inhibitor of apoptosis (XIAP). In the rescue experiments, pharmacological activation of NF-κB by tumor necrosis factor-α (TNF-α) partially recovered cell proliferation after the knockdown of DOK3.Conclusion::Our findings suggest that overexpression of DOK3 promotes PCa progression by activating the NF-κB signaling pathway.
