Literature has documented that student nurses undergo stress in their academic and clinical setting. This raises concerns because stress during undergraduate training may result in psychological or emotional impairment during the nurses’ professional life and ultimately affect the quality of patient care. The Objective of the study was to study the prevalence of stress, and the association between sociodemographic factors, stressors and coping strategies with stress. This was a cross-sectional study on 96-year 1-3 nursing students from a government university done between 2015-2018. Bahasa Malaysia translated The General Health Questionnaire, Stressors in Nursing Student Scale Questionnaire and Brief COPE Questionnaire was used in this study. This study had Malay (95.9%) and female (91.7%) dominated population. The prevalence of stress in student nurses was 25%. No association was reported between sociodemographic factors and stress. Among the 4 stressors educational, clinical, confidence and financial, clinical stressor scored the highest mean 6.40 (SD±3.66). Confidence stressor (AOR=1.26 95% CI 1.04-1.53) was the only stressor associated with stress. The top 3 coping strategies practiced by the student nurses were religion (praying), acceptance and planning. Self-blame (AOR 8.18 95% CI 1.86-35.91) was the only coping strategy associated with stress. Stress management programmes, and workshops on stress and coping strategies should be conducted yearly to ensure a well-balanced environment for good learning experiences and prevent stress related health problems and improved academic performance.

Aim To investigate the effect of adenosine on the autophagy and proliferation of hepatocellular carcinoma cells, and improve the curative effect of a-denosine on hepatocellular carcinoma. Methods HepG2 cells were incubated with adenosine, CCK-8 method was used to study the changes of cell prolifera-tion,Western blot was used to study the expression of LC3-Ⅱ and LC3-Ⅰ, and MDC staining was used to observe the number of autophagosomes. Results HepG2 cells were incubated with adenosine(1.0~4.0 mmol·L-1) for 48 h,the proliferation of HepG2 cells were detected at the different time points (12,24,48 h),and the result showed the proliferation was signifi-cantly inhibited by adenosine (P < 0.01). HepG2 cells were incubated with adenosine (0.2,0.5,1.0, 2.0,4.0 mmol·L-1) for 24 h,the ratio of LC3-Ⅱ/LC3-Ⅰ decreased significantly in low concentration of adenosine group (0.2, 0.5 mmol·L-1, P <0.05;1.0 mmol·L-1,P<0.01),and the ratio of LC3-Ⅱ/LC3-Ⅰ increased significantly in higher concentration of adenosine group (4.0 mmol·L-1, P <0.05). HepG2 cells were incubated with adenosine(1.0 mmol·L-1) for 24 h, the ratio of LC3-Ⅱ/LC3-Ⅰ de-creased significantly at 6,12 and 24 h detecting point, the number of autophagosomes were reduced, the low-est ratio of LC3-Ⅱ/LC3-Ⅰ and autophagosomes were observed at 12 h detecting point(P<0.01). Conclu-sions Adenosine inhibits the proliferation of hepato-cellular carcinoma cells,the low concentration of aden-osine inhibits the autophagy,while the high concentra-tion of adenosine increases the autophagy, which is of great significance to reduce multi-drug resistance and improve the therapeutic effect of anti-hepatoma drugs.
