Objective: To explore the association between stress, coping style, social support and subjective well-being (SWB) of college Students. Methods: 1773 college students from 8 colleges in Guangzhou were tested with Index of Well-being Questionnaire, College Students’ Stress Scale, Simplified Coping Style Questionnaire(SCSQ) and Social Support Rating Scale (SSRS). And structural equation model (SEM) was built based on the data. Results: SEM revealed ?2/df=2.837, RMSEA=0.032, and indexes of GFI、AGFI、NFI、NNFI、CFI were all above 0.9. Stress and passive coping style had passive effect on SWB (the overall regression weights were -0.377 and -0.130 respectively). Social support and positive coping style had positive effect on SWB (the overall regression weights were 0.286 and 0.277 respectively). Conclusion: Stress, coping style and social support are important forecast variables of SWB.

BACKGROUND: Some scholars thought that social support is one of the key factors in determining self-esteem, and most scholars thought that subjective support is more meaningful than objective support. Yet on the domain of social support, Chinese scholars still put forward a problem about utilizations of social support besides subjective and objective support. However,how is the relationship between self-esteem and social support, especially the utilizations of social support in college students?OBJECTIVE: To probe into relationship between self-esteem and social support of college students and understand self-esteem and social support status of them.DESIGN: Cluster sampling and present situation study based on college students.SETTING: Department of medical psychology and behavior science in medical college of a university.PARTICIPANTS: Totally 154 comprehensive college students in south China were investigated.METHODS: Adopting self-esteem scale(SES) and social support questionnaire(SSQ) to conduct a self-evaluating investigation among 154 students in a comprehensive university in south China.MAIN OUTCOME MEASURES: The scores on SES and SSQ on three dimensions for 154 college students.RESULTS: The boy college students got higher scores on self-esteem than that of girls' ( t = 2. 510, P ＜ 0: 05). Non-only-child college students' total scores and utilizations of social support were significantly higher than only child college students(t= -1.983, P ＜0.05; t= -3.475, P=0.01).The self-esteem was significantly positive correlated with the utilization of social support.CONCLUSION: College students'self-esteem is related to social support.

AIM: To investigate the mutagenicity of cadmium and zinc and the effect of zinc on the mutagenicity of cadmium. METHODS: The frequency of sister chromatid exchange (SCE) induced by cadmium, zinc and the combination of cadmium and zinc were observed in cultured human lymphocytes. RESULTS: Cadmium induced the increase in frequency of SCE in human lymphocytes from the concentration 1?10~(-8) mol/L to 1?10~(-6) mol/L, but zinc had a negative result. Zinc reduced the frequency of SCE induced by cadmium at the concentration from 1?10~(-6) mol/L to 1?10~(-4) mol/L and a relationship between dose and effect was also observed. CONCLUSION: Zinc inhibits the mutagenicity of cadmium in cultured human lymphocytes.

Objective To evaluate effects of mindfulness-based relapse prevention treatment in female incarcerated substance abusers with protracted withdrawal syndromes.Methods 120 female incarcerated substance abusers were selected from compulsory rehabilitation/treatment center,they were randomly assigned by throwing coin to either treatment group or control group.All participants in treatment group got mindfulness-based relapse prevention treatment.At pre- and post-session assessment points,all participants completed the Five Factor Mindfulness Questionnaire and Opiate Protracted Abstinent Symptoms Scale.Two sample t -test and chi-square were used to examine the baselines,repeated measures ANOVA for assessing changes of mindfulness and protracted abstinent syndromes between and within groups.Results No differences between-group were found on mindfulness and protracted abstinent syndromes.Group x Time effects emerged for observe facet (F=27.87,P=0.000),describe facet(F=15.10,P=0.000) and total scores of mindfulness (F =12.05,P=0.001 ),the same as craving symptoms(F=7.53,P=0.007) and sleeping symptoms (F=4.40,P=0.038) of protracted abstinent symptoms.On sleep symptoms,participants in treatment group got(5.7 ±4.0) score before treatment points,got (3.5 ±3.1 )after treatment points.Participants in control group got (4.3 ± 3.6) at pre-session assessment,got (3.7 ± 3.5 ) at post-session assessment,participants in treatment group got better improvement in sleeping symptoms.Physical symptom score of protracted abstinent symptoms among treatment group participants showed a downward trend over time(F=14.89,P =0.000).Conclusion Mindfulness-based relapse prevention treatment can increase mindfulness scores,and improve physical and sleeping problems.Compulsory rehabilitation center is helpful for substance abusers.
