Objective To explore the effects of self-management strategies on self-efficacy and selfmanagement behavior in female college students with primary dysmenorrhea.Methods Implementing the plan that the interventional group (n=195) received self-management strategies,while the control group (n =196) did not received any intervention.Followed up six months,the self-efficacy and self-management behaviors and Visual Analogue Scale/Score (VAS) of dysmenorrhea pain were compared between two groups before and after the intervention.Results At the 6th month of observation period,the scores of self-efficacy in the intervention group (2.61 ±0.48) were significantly improved compared with the baseline (2.37 ± 0.36) and the control group(2.43±0.46) (both P＜0.05).Besides taking medicine to alleviate dysmenorrhea,other items in the self-management behaviors were significantly higher than baseline and control group (both P＜ 0.05).The mean of dysmenorrhea pain VAS of 6th menstrual period in the intervention group was lower than baseline and the control group (P＜0.05).Conclusion The self-management strategies can effectively improve the self-efficacy and self-management behaviors among female college students,and alleviate the degree of dysmenorrhea pain.

To explore the allocation and equity of health resource in Changsha between 2007 and 2013 and to provide references for government to carry out regional health planning. Method:General statistical analysis was used to describe changes of health resource allocation in Changsha;from the perspective of the population and geography of the nine counties in Changsha, the equality and change of the configuration among doctors, nurses and hospital beds were analyzed by using the Gini coefficient and Theil index. Results:1) The per capita amount of health resources in Changsha increased gradually, and health resources were mainly concentrated in urban areas. 2 ) The Gini coeffi-cients of doctors, nurses and hospital beds was 0. 24~0. 46 according to population distribution between 2007 and 2013 in Changsha, and the Gini coefficient of all health resources by geography was 0. 59~ 0. 79 and peaked in 2009 to then decrease year after year. Following a comparison of the two kinds of regions, the Gini coefficient of urban are-as was significantly higher than that of rural areas, and the Gini coefficient of nurses was the highest among all health resources. 3) Changes in the Theil index were consistent with the Gini coefficient. The difference in the degree of re-source allocation in urban areas exhibited a rising trend, The Theil index was higher than each regional difference. Conclusion:Overall, the equity of allocation of health resources in Changsha between 2007 and 2013 gradually im-proved year by year. The equity of population configuration was greater than that of geographical configuration, and the equity of rural areas was superior to that of urban areas;the equity of the configuration of nurses was poor. The difference between areas is the main factor affecting the equity of Changsha’s health resource allocation.

Objective To investigate the current status of self-management action of patients with chronic kidney disease (CKD) during early-mid stage and its influencing factors. Methods 80 patients were recruited in a tertiary hospital in Beijing from March to June 2011.They were surveyed with a self-designed self-management action questionnaire of patients with CKD. Results The total score of self-management action in patients with CKD was(69.10±5.63 ).1.25％ patients with CKD had bad self-management ability and 88.75％ patients had moderate self-management ability,only 10.00％ patients had good self-management ability.Patients of younger age,with higher education level,ever attending lectures or having inpatient experience had better self-management ability.And the methods of payment also had significant influence on the self-management of patients with CKD. Conclusions When taking care of patients with CKD,health care providers should be more individual case-based,especially paying more attention to those who are older,with low education degree,never have attended health education lectures and do not have inpatient experience,in order to increase patients' self-management ability and help them improve their health status.

Objective:To understand suicide prevention knowledge, suicide attitude and related factors among undergraduates in Changsha.Methods:Using multistage stratified cluster sampling, a total of 1664 undergraduates from six universities in Changsha were tested with Suicide Awareness Questionnaire, Suicide Attitude Questionnaire (QSA), Adolescent Self-Rating Life Events Check List (ASLEC), Social Support Questionnaire (SSQ) and Symptom Checklist 90 (SCL-90). Results:The mean score of suicide awareness among undergraduates was 10.8?0.9 and the correct response rate was 54.5%. The result of suicide awareness score showed, female undergraduates had a lower score than males (9.2?0.8, 12.3?0.8;t=2.33, P=0.020), medical undergraduates had a higher score than ones of humanities and social science or engineering (13.9?0.8, 10.0?1.0, 9.7?0.7;F=10.47, P=0.000), undergraduates from one-child families had a higher score than ones from non-one-child families (11.9?0.7, 9.1?0.9;t=3.25, P=0.034), and college students from nuclear family had a higher score than ones from extended families or one-parent families (14.0?0.9, 10.3?0.8, 9.4?0.7;F=7.49, P=0.000). The major factors related to suicide awareness were gender, specialty and family type (?=0.087, 0.342 and 0.084, respectively). And the major factors related to attitude towards attributes of suicide behaviors were specialty, gender, suicide ideation and mental health status (?=0.688, -0.055, 0.810 and 0.731, respectively). Conclusions:College students in Changsha have severe misunderstands about suicide prevention. It is necessary to pay more attention to the education of suicide knowledge and to cultivate the correct suicide attitude among college students.

AIM: To study the role of hypoxia-inducible factor-1alpha(HIF-1?) on lung cancer cells A549 growth in vitro and in vivo. METHODS: To observe the growth rate of A549 cells after HIF-1? transfected, A549 cells (1?10~6/mouse) were inoculated subcutaneously into 20 nude mice, which were randomly divided into two groups: the control group (group A, n=10), the HIF-1? transfected group (group B, n=10). The weights of subcutaneous tumor were detected. The resected specimens were made into paraffin-embedded sections. The proliferating cell nuclear antigen (PCNA) was identified by immunohistochemistry(ISH). The expressions of HIF-1?? apoptosis-related protein survivin and bcl-2 were analyzed by Western blot. RESULTS: The growth rates of the HIF-1? transfected lung cancer cells A549 were significantly increased, and more importantly, the HIF-1? transfected lung cancer cells A549 was able to enhance lung cancer growth in nude mice(P

Objective: To investigate the suicide ideation and related risk factors in laid-off workers in Changsha Method: By cluster sampling, 675 laid-off workers of 6 factories were collected 675 workers still at work matched by sex and age were collected as control All subjects completed Suicide Ideation Questionnaire, SCL-90, SES (self-esteem scale), TCQ (trait coping questionnaire), SSRS (social support rating scale) and LES (life event scale) Among all them, the data of 6 subjects was incomplete, therefore totally there were data of 1344 subjects (rate of drop-off was 0 4%) One-way and multiple logistic regression were employed to identify risk factors for suicide ideation Results: About one in four laid-off workers (23 4%) reported suicide ideation, 4 6% had a suicide plan or thought of exact methods, 2 8% had attempted suicide after unemployment Multiple unconditioned logistic regression analysis showed that the major risk factors for suicide ideation were suicide ideation before unemployment, poor mental health, negative coping style, recent life events, low income, poor social support and poor education Conclusion: The prevalence of suicide ideation among laid-off workers is much higher than that of general population Improving their mental health may be a helpful way to prevent suicide

Objective: To investigate the loneliless situation of the elderly, and explore the relationship between loneliness,filial expectations and intergenerational social support among the elderly. Methods: Using UCLA Loneliness Scale, Intergenerational Social Support and Fealty Expectation Questionnaire, we investigated 423 samples of old people aged 60 ～94 of Changsha City. Results: The mean score of loneliness was 39.8 (s =7.3). Ordinal regression analysis indicated that the loneliness of the elderly was significantly related to received adult children social support (OR=2.208, P=0.006),afforded adult children social support(OR=2.056,P=0.01) and filial expectation(OR=1.872,P=0.027),controlled by age, sex, level of education, marriage, level of family income, and residence status. Filial expectation directly affected loneliness and indirectly affected loneliness through received adult children social support and afforded adult children social support. Conclusion: The loneliness of the elderly are significantly related to filial expectation and intergenerational support.

AIM: To investigate the effects of NF-?B decoy oligodeoxynucleotides (ODNs) on apoptosis in lung cancer cell A549. METHODS: The treatments of lung cancer cells (A549) were divided into three groups: group A (control group); group B (decoy ODN group) and group C (scramble decoy ODN group). FITC-labeled NF-?B decoy ODNs was transfected into A549 with LipofectAMINE TM 2000. The activation was observed by electrophoretic mobility shift assays (EMSA). The proliferation was observed by growth curve. The apoptosis of cells were observed by flow cytometry and TdT mediated dUTP-biotin Nick End Labeling (TUNEL). The expression of Bcl-2 and Fas were observed by Western blot. RESULTS: After FITC-labeled decoy ODNs was transfected for 1 hour, the decoy ODNs was detected in the nuclei of A549 cells. EMSA performed the depression of the NF-?B binding to the nucleus. The growth curve showed the inhibition of the A549 cell growth and the percentage of apoptosis was increased compare with control group by flow cytometry and TUNEL. The amount of apoptosis inhibitor (Bcl-2) in group A and group C were 2.0 times and 2.1 times more than that in group B, respectively. The level of apoptosis accelerator (Fas) in group B were 2.6 times and 2.3 times more than that in group A and group C, respectively via Western blot. CONCLUSION: The NF-?B decoy ODNs accelerate the apoptosis of lung cancer cell A549 and the mechanism may be due to its inhibiting the expression of Bcl-2 and increasing the level of Fas. [
