Objective:To find out the role of JNK/SAPK signaling-transduction pathway in the effect of elemene against hepatocarcinoma, offering the clue to ilustrate the molecular mechanisms of antitumor effects of elemene. Methods: The detection of the distribution of elemene in Hca-F cells was detected by gas chomatography and apoptotic changes in elemene treated. SMMC7721 cells were examined by TEM. After elemene treatment, the activation of JNK/SAPK in HepG2 cellls and the DAXX gene expression in SMMC7721 cells were detected by Western blotting and RT-PCR respectively. Results: Gas chomatography showed that elemene was detected at 8. 42 minute. The SMMMC7721 cells treated by elemene for 3 hours began to show typical apoptotic changes . The JNK/SAPK activity in HepG2 cell treated with heat shock was the highest of all groups and the group treated with elemene was the next and the control group is the lowest one. There was no DAXX gene expression in SMMC7721 cells treated with elemene. Conclusion: Elemene can diffuse into cells. Tumor cell apoptosis treated with elemene may be induced by JNK/SAPK activating and DAXX signal pathway may not play key role in JNK/SAPK activation induced by elemene.

Objective To explore the patients satisfaction with participation in medical and nursing decision making and the influencing factors among cancer patients, and to provide a basis for developing better medical care services. Methods Totally 159 cancer patients were recruited from Beijing Cancer Hospital, and then were investigated with the general information questionnaire, the patients′ expectation for participation in clinical decision making scale, the patients′ competence for participation in clinical decision making scale, and the patients′satisfaction with participation in medical and nursing decision making questionnaires. Results The total score of patients′satisfaction with participation in medical and nursing decision making were (45.92±3.91) and (34.25±3.31) respectively. Compared with female patients, male patients had higher satisfaction with medical decision making (46.45±3.24&44.87±4.84) and nursing decision making (34.68 ± 2.93&33.42 ± 3.84) (t=2.416, P=0.017;t=2.275, P=0.024);and compared with melanoma patients, lung cancer patients had higher satisfaction with medical decision making (46.51 ± 2.69&43.33 ± 7.07, P=0.002);compared withⅢstage patients, Ⅳstage patients had higher satisfaction with nursing decision making(34.97±2.24&32.40±4.56, P<0.01). Meanwhile, the satisfaction with participation in decision making was significantly positively associated with patients′ expectation and competence for participation in clinical decision making. Conclusions Patients′satisfaction for decision making may vary from different gender, tumor types, disease stages, and patients′expectation and competence. Health care providers still further strength patients′ knowledge and initiative of decision making, and then improve patients′satisfaction with participation in decision making.

Objective To explore the effect of high quality nursing intervention on psycho-logical state and the quality of life in patients with metabolic syndrome.Methods 150 patients with metabolic syndrome were randomly divided into control group and observation group with 75 cases in each.The control group was given the routine nursing method while the observation group received high quality nursing.Psychological state,understanding ability of social support and the quality of life of two groups of patients were analyzed.Results After the intervention,anxiety score in the observation group was lower than that in the control group and score of self-esteem scale and understanding score of social support in the observation group was higher than that in the control group,the results revealed that the difference was statistically significant (P <0.01).Af-ter the intervention,the improvement of indicators of quality of life in observation group was better than that in the control group ,thus ,the difference statistically significant (P < 0 .0 1 or P <0.05).Conclusion High quality nursing has significant effect for patients with the metabolic syn-drome.It can effectively improve the patient’s psychological status and quality of life,so it is wor-thy of clinical application.

Objective:To investigate the effects of liraglutide on the expressions of autophagy markers LC3B, LC3B mRNA and lipid deposition in myocardial tissue of rats with early diabetes mellitus.Methods:A total of 36 healthy male Wistar rats aged 4-5 weeks and weighing (l80-200) g were selected and divided into normal group (group NC, 10 rats) and model group (26 rats) according to random number table. Rats in the NC group were fed with routine diet and rats in the model group were given high glucose and high fat diet for 12 weeks. Rats in the model group were injected with streptozotocin into the abdominal cavity in a single dose of 25 mg/kg after molding. Rats in the model group were further divided into three groups: T2DM group (group DM/NS, 9 rats, given equal volume of saline) , liraglutide intervention group (group DM/LIR, 8 rats, injected with 100 μg/kg liraglutide twice daily) and Liraglutide and Chloroquine intervention group (group DM/LIR+CQ, 8 rats, injected with 100 μg/kg liraglutide twice daily, and injected with Chloroquine 50 mg/kg once every two days) . Rats in group NC were given equal volume of saline. At the end of 12 weeks, all the rats were tested blood glucose and anaesthetized to collect myocardial tissues to observe myocardial lipid deposition and fiber arrangement under light microscope after HE staining. The expressions of LC3B were detected by immunohistochemical method, and the expressions of LC3B mRNA were detected by real-time fluorescence quantitative polymerase chain reaction method. Differences among groups were compared by one-way analysis of variance, pairwise comparison was conducted by using LSD-t test, correlation was analyzed by Pearson correlation.Results:(1) Compared with group NC, the myocardial fibers arranged in disorder, and the ratio of myocardial foam cells/total cardiomyocytes were increased, the level of LC3B mRNA and LC3B were decreased in group DM/NS and DM/LIR+CQ (in group DM/NS: 2.18±0.90 vs 11.79±0.74, 2.03±0.10 vs 1.85±0.06, 194.18±10.19 vs 175.99±6.09, t=25.24, 4.69, 3.22, respectively; in group DM/LIR+CQ: 2.18±0.90 vs 11.24±1.29, 2.03±0.10 vs 1.89±0.08, 194.18±10.19 vs 176.73±7.82, t=17.56, 4.65, 3.99, respectively, all P<0.05) . There is no difference in above indicators (2.18±0.90 vs 1.29±0.60, 2.03±0.10 vs 2.01±0.20, 194.18±10.19 vs 201.27±11.35, t=2.20, 0.28, 1.40, respectively, all P>0.05) . (2) Compared with group DM/NS, the ratio of myocardial foam cells/total cardiomyocytes, the level of LC3B mRNA and LC3B were no difference in group DM/LIR+CQ ( t=1.09, 1.18,0.22, respectively, all P>0.05) . The ratio of myocardial foam cells/total cardiomyocytes was decreased, the level of LC3B mRNA and LC3B were increased in group DM/LIR (11.79±0.74 vs 1.29±0.60, 1.85±0.06 vs 2.01±0.20, 175.99±6.09 vs 201.27±11.35, t=31.86, 2.39, 5.82, respectively, all P<0.05) . (3) The significant negative correlation were observed between the ratio of myocardial foam cells/total cardiomyocytes and LC3B mRNA, LC3B levels (r=-0.977, -0.986, respectively, all P<0.05) . Conclusion:Liraglutide can protect the myocardial structure in early diabetic rats by increasing myocardial autophagy, reducing the number of myocardial foam cells, and improving the myocardial lipid deposition.
