Objective To investigate the level and influencing factors of subjective well-being of nurses and establish a model of the relationship of job stress, self-efficacy and subjective well-being. Methods Totally 438 nurses from 5 hospitals in Changchun city were investigated with the self-designed demographic questionnaire, General Well-Being Scale, Nurse Job Stressors Scale and Self-Efficacy Scale. Results The total score of subjective well-being was (71.36 ± 18.83) points. Single factor analysis found that age (F=1.759, P<0.01), department (F=1.712, P<0.01), professional title (F=1.364, P<0.05), years of working (F=1.420, P<0.05) and monthly income (F=1.632, P<0.01) were statistically significant. Multiple linear regression analysis showed that sex (t=-2.447, P<0.05), the first factor of job stress (t=-5.033, P<0.01), the second factor (t=-2.478, P<0.05), the third factor (t=-2.315, P<0.05), the fifth factor (t=-5.862, P<0.01) and self-efficacy (t=10.705, P<0.01) were the predictive effectton of subjective well-being. The result of path analysis shows that self-efficacy has a significant effect of adjustment on job stress and subjective well-being (direct effects=-0.62, indirect effects=-0.24, P<0.01). Conclusions The nurse subjective well-being is in the medium level. Hospitals and all related departments should take effective measures to reduce or eliminate unfavorable factors and increase the protective factors, and then improve the level of nurses′subjective well-being and nursing quality.

Objective:To investigate the therapeutic effect of continuous blood purification (CBP) on acute pancreatitis (AP) and its influence on prognosis.Methods:200 patients with AP in our hospital from January 2010 to December 2016 were selected as the subjects,and they were divided into conventional treatment group and CBP treatment group according to the random number table method,600 cases in each group.The conventional treatment group was received conventional drug therapy,and the CBP treatment group was treated with CBP on the basis of commonly used drugs.The disappeared time of clinical symptoms after treatment and the changes of inflammatory factors and the changes of intestinal function before and 72 h after treatment were compared between the two groups,the mortality rate was compared between the two groups at 7 d after treatment.Results:Abdominal pain disappeared time,abdominal distension disappeared time and abdominal tenderness disappeared time in CBP treatment group after treatment were lower than the conventional treatment group (P＜0.05).There was no significant difference in the levels of endotoxin,C reactive protein (CRP),amylase (AMS),two amine oxidase and malondialdehyde before treatment in the two groups (P＞0.05).At 72 h after treatment,endotoxin,CRP,AMS,two amine oxidase and malondialdehyde levels were lower than those before treatment,and the CBP treatment group was lower than the conventional treatment group (P＜0.05).The mortality rate of CBP treatment group was lower than that of conventional treatment group at 7 d after treatment,the difference was statistically significant (P＜0.05).Conclusion:CBP can effectively improve the clinical therapeutic effect of AP,and improve the clinical prognosis of patients.

Objective To explore the influence of introducing standardized patient (SP) into problem-based learning (PBL) to the autonomous learning abilities for undergraduate nursing students based on clinical thinking training. Methods To select 2 classes randomly from full-time professional nursing undergraduate classes enrolled in 2012 from Tianjin university of traditional Chinese medicine, was divided into the experimental group and the control group by random number table method. The control group uses PBL teaching mode, and the experimental group adopts introducing SP into PBL teaching mode. Course lasts for 4 weeks, a total of 18 hours. To evaluate two groups nursing students′the percentage of asking questions by themselves and examination results in the end of the course, and evaluate nursing students′autonomous learning ability before and after the course and after three months of clinical practice respectively. Results The percentage of asking questions by themselves and examination results of the experimental group were 87.80%(36/41) and (84.24±5.12) points, (87.85±5.44) points, the control group were 68.89%(31/45) and (81.51±6.63) points, (84.40±7.96) points, the difference was statistically significant (χ2=4.46, t=2.13, 2.37, P<0.05);There was no statistical significance between two groups in the score of autonomous learning ability before the course (P>0.05), while after course and after three months of clinical practice of the experimental group were (93.71±9.56) points, (103.27±11.92) points, the control group were (85.47 ± 9.28) points , (91.36 ± 10.56) points, the difference was statistically significant (t=3.56, 4.89, P<0.01). Conclusions The teaching mode of introducing SP into PBL can train and improve the autonomous learning ability of undergraduate nursing students,and can provide reference for nursing teaching mode reform.

Object To develop a method of multiplying virus free clonal seedlings of CV.85 5 of Rehmannia glutinosa (Gaert.) Libosch. ex Fisch. et Mey.. Methods The leaf cut segments with or without tips of plantlets were grown in different media (mg/L) (1.MS+BA 0.5; 2 MS+BA 0.5+NAA 0.02;3 MS+BA 0.5+NAA 0.02+GA 3 0.1; 4 1/2 MS+BA 0.1; 5 1/2 MS+BA 0.1+GA 3 0.1; 6.1/2 MS+GA 3 0.1) to select a suitable medium, and the height and the numbers of newly formed leaves and roots were recorded 30 days later. To screen out a favorable condition, similar segments were transferred to No.2 medium at different temperatures in different illuminations, and the height together with the leaf number and the fresh weight of the plantlets was recorded.Results In the former three media, the segments with tips were flourishing and one to three axillary buds were formed at its basal stem; while in those without tips almost every axillary bud developed with the main tip length 0.5～1.5 cm. In the later three media, thd elongation of the segments was usually overstimulated, and the slim plantlets with fewer leaves and more roots formed. When the segments cultured in No.2 medium, all records at 28 ℃ were higher than those at 23 ℃ in the same illuminations. But the leaf size and the height of the plantlets were inversely proportional to the intensity of illumination at the same temperature. In addition, antagonism between BA and GA 3 was found.Conclusion No.2 medium is more suitable for the multiplication of the virus free seedlings of 85 5 when cultured at 28 ℃ in the illumination of 1 000～2 000 lx.

Alectinib, an inhibitor of anaplastic lymphoma kinase (ALK), was approved by the Food and Drug Administration (FDA) for the treatment of patients with ALK-positive non-small cell lung cancer (NSCLC). Here we investigated the reversal effect of alectinib on multidrug resistance (MDR) induced by ATP-binding cassette (ABC) transporters, which is the primary cause of chemotherapy failure. We provide the first evidence that alectinib increases the sensitivity of ABCB1- and ABCG2-overexpressing cells to chemotherapeutic agents in vitro and in vivo. Mechanistically, alectinib increased the intracellular accumulation of ABCB1/ABCG2 substrates such as doxorubicin (DOX) and Rhodamine 123 (Rho 123) by inhibiting the efflux function of the transporters in ABCB1- or ABCG2-overexpressing cells but not in their parental sensitive cells. Furthermore, alectinib stimulated ATPase activity and competed with substrates of ABCB1 or ABCG2 and competed with [125I] iodoarylazidoprazosin (IAAP) photolabeling bound to ABCB1 or ABCG2 but neither altered the expression and localization of ABCB1 or ABCG2 nor the phosphorylation levels of AKT and ERK. Alectinib also enhanced the cytotoxicity of DOX and the intracellular accumulation of Rho 123 in ABCB1-overexpressing primary leukemia cells. These findings suggest that alectinib combined with traditional chemotherapy may be beneficial to patients with ABCB1- or ABCG2-mediated MDR.
