Objective To describe the status of nurse work engagement and to explore the relationship between work engagement and work-related flow experience.The study results provided the basis for how the nurse managers stimulate enthusiasm of nurses and let them devote themselves to work.Methods A convenience sample of 127 nurses from one major hospitals in Beijing city was recruited.Work Engagement Scale and Work-related Flow Experience Questionnaire were used in this study.Results The scores of work engagement were (3.18±0.59),at moderate level.Age,education level and professional titles were the influential factors of nurses' work engagement.The scores of work-related flow experience were (3.48±0.45),at moderate level.The scores of clear goals,focus on tasks,balance of skills and challenges were the top three dimensions of the work-related Flow Experience Questionnaire.Except for the two dimensions,the integration of action and awareness and the weakening of self-awareness,other dimensions of the work-related flow experience appeared statistically significant correlation to the scores of work engagement (P＜0.05 or P＜0.01).Most were moderate positive correlations.Conclusions Both the work engagement and the work-related flow experience are at moderate level.The nurse managers needed to take active measures to enable nurses to have more positive experiences and happiness,so as to enhance nursing work input,to improve quality of care and job satisfaction.

AIM:To observe the situation of rat retinal tissue DNA damage at early diabetic period, discuss the role of the blood glucose fluctuations, and provide a new method for studying the pathogenesis of diabetic retinopathy ( DR) .
METHODS: SD rats were randomly divided into four groups:normal control group (NC), normal fluctuation group ( NF ) , diabetes group ( DM ) and diabetes fluctuation group ( DF ) . Diabetic models were established through intraperitoneal injection of STZ. A certain amount of glucose was injected in the rats of group NF and DF in an intraperitoneal mode three times a day after the model was established, thereby causing blood glucose fluctuations. Rats were killed and the retinal tissues were taken in the 8th week. Single cell gel electrophoresis ( SCGE ) technique was adopted for detecting DNA injury extent in the retina tissue.
RESULTS:Groups NF and DF showed significant and regular fluctuations. The curve of blood glucose fluctuations was relatively stable. All values of MBG, SDBG, LAGE and M were significantly increased compared with group NC. Group DF was increased more significantly. It was statistically significant (P<0. 01). SCGE showed that there were DNA damages in different levels in the cells of group NF, DM and DF. Indicators of cells such as TL, TDNA %, TM, OTM were higher than that in group NC. It was statistically significant ( P<0-01). The comparison difference between two groups was also significant (P<0. 01).
CONCLUSION: Rat retinal tissues have DNA injury during early diabetic period. DNA injury is gradually aggravated with blood glucose fluctuation. It indicates that high blood glucose and blood glucose fluctuation are involved in the mechanism of cell DNA injury, and they may be one of DR early event, have played a certain role in the incidence of DR.

Objective To examine the reliability,validity,and practicability of Cognitive Emotion Regulation Questionnaire (CERQ) in hypertensive patients in China.Methods Altogether 434 hypertensive patients and 462 healthy subjects were recruited. All the subjects were assessed with the CERQ-Chinese version (CERQ-C), Dysfunctional Attitude Scale (DAS), Mood and Anxiety Symptom Questionnaire-Short Form (MASQ-SF), and Center for Epidemiologic Studies Depression Scale (CES-D). We calculated the mean inter-item correlations for the total CERQ and for each of the subscales. Cronbach's alpha coefficient was used to analyze the inter-correlation and reliability, and confirmatory factor analysis was used to examine the 9-factor model. Results 1) Hypertension group reported significantly higher score than that of healthy ones on rumination (12.19±2.51 vs. 11.51±2.60, P<0.001), catastrophizing(8.82±2.19 vs.8.11±2.70,P<0.001),and blaming others(10.76±2.11 vs. 9.88±2.48,P<0.001), and had significantly lower score than that of healthy ones on positive reappraisal(13.80±3.55 vs.14.71±4.11,P<0.001).2)Reliability:In the hypertension group the Cronbach's alpha for the total CERQ was 0.80, and that for the 9 subscales ranged from 0.71 (self-blame) to 0.90 (rumination). In the healthy group the Cronbach's alpha for the total CERQ was 0.79, and that for the 9 subscales ranged from 0.71 (positive reappraisal) to 0.90 (rumination). The mean inter-item correlation coefficient for the 9 subscales was 0.21-0.42(the hypertension group)/0.19-0.32 (the healthy group). In the hypertension group,the test-retest reliability of the total scale was 0.82, the test-retest reliability of the 9 subscales ranged from 0.73 to 0.92. The confirmatory factor analysis showed that the 9 first-order factor data fitted both 2 samples well. Conclusion CERQ meets the psychometric standard and it is reliable and valid for cognitive emotion regulation strategies, which may be regarded as an appropriate assessment tool.

OBJECTIVETo observe the effect of sodium tanshinone II (A) sulfonate (STS) on Ang II -induced atrial fibroblast collagen synthesis and TGF-beta1 activation.

METHODAtrial fibroblasts of neonatal rats were cultured to determine the content of collagen protein. The original synthesis rate determined by the [3H]-proline incorporation method was taken as the index for myocardial fibrosis. The content of active TGF-beta1 and total TGF-beta1 in cell culture supernatants were tested and cultured by ELISA. The expression of thrombospondin-1 (TSP-1) was assessed by using Western blot.

RESULTAng II could significantly increase the content of atrial fibroblast collagen and the collagen synthesis rate, the TSP-1 expression and the concentration of active TGF-beta1, without any obvious change in total TGF-beta1. After the STS treatment, all of the indexes, apart from total TGF-beta1, were obviously down-regulated.

CONCLUSIONSTS could decrease the secretion of Ang II -induced atrial fibroblast collagen and the synthesis rate. Its mechanism is related to the inhibition of TSP-1/TGF-beta1 pathway.

Currently, bacterial resistance situation in health care settings is very serious in China, and the prevalence of a variety of common multidrug-resistant bacteria and pan-resistant bacteria are relatively high. Drug-resistant bacteria in Gram-positive bacteria are mainly methicillin resistant Staphylococcus aureus ( MRSA ) and macrolide-resistant Streptococcus, while glycopeptide-resistant enterococci are still at a low level.The clonal distribution of MRSA and mechanisms of Streptococcus resistance in China are different from those in European and American countries.Cephalosporins and quinolones resistance are the marked characteristic of Enterobacteriaceae with a high occurrence over 60%. Carbapenem-resistant Klebsiella pneumoniae shows a rapid upward trend, and producing KPC-2 type carbapenemases is the main mechanism of its resistance.Resistance in Pseudomonas aeruginosa is relatively stable, with resistant rates ranging from 20%to 30%.Multi-drug resistant Acinetobacter baumannii is a big problem in clinic.More than 50% Acinetobacter baumannii strains are resistant to carbapenems and cephalosporins, and tigecycline-resistant Acinetobacter baumannii is increasing.This paper systematically reviews the status and characteristics of bacterial resistance in last five years with referring to the surveillance data of antimicrobial resistance and the findings of related mechanisms.

Objective To observe the effect of neutralizing monoclonal antibodies to antiglomerular basement membrane (GBM) antibody on anti-GBM nephritis rats. Methods Wistar rats were randomly divided into five groups: control group Ⅰ was a negative control and was injected with healthy human IgG via the caudal vein. Control group Ⅱ was injected with neutralizing monoclonal antibodies to anti-GBM antibody only. Anti- GBM nephritis group was injected with human anti-GBM antibody via the caudal vein only. Intervention group Ⅰ was injected with human anti-GBM antibody via the caudal vein and then with neutralizing monoclonal antibodies to anti-GBM antibody at day 7. Intervention group Ⅱ was injected with human antiGBM antibody via the caudal vein and then with neutralizing monoclonal antibodies to anti-GBM antibody at day 14. The blood, urine and kidney tissue were collected at day 7, 14, 21 for analysis of 24-hour urinary protein, BUN, Ser and histological study. Results At day 21, there were significant decreases in intervention group Ⅰ compared with anti-GBM nephritis group in 24-hour proteinuria [(16.62±5.53) g], BUN[(11.53±2.26) mmol/L] and Scr [(102.46±16.86) μmol/L] (P＜0.05), and also in intervention group Ⅱ as compared to anti-GBM nephritis group, but no significant difference was found (P＞0.05) . There was obvious decrease of renal cell proliferation,crescent formation and deposition of immune complexes in intervention group Ⅰ and intervention group Ⅱ compared with anti-GBM nephritis group, while such improvement in intervention group Ⅰ was more significant. There was no significant change in control group Ⅰ and control group Ⅱ.Conclusion The early application of neutralizing monoclonal antibodies to anti-GBM antibodies can effectively improve the kidney lesions of anti-GBM nephritis rats.

Objective To explore the regulation mechanism of autophagy-related protein, microtubule-associated protein 1 light chain 3 (LC3), via c-Jun in methotrexate resistant human choriocarcinoma JEG-3 cell lines. Methods Human choriocarcinoma JEG-3 cell lines, and methotrexate resistant choriocarcinoma JEG-3 (JEG-3/MTXR) cell lines were used in our present study. Phosphorylation c-Jun (p-c-Jun) was evaluated after exposure to 0.02 ng/ml methotrexate for 72 hours in both cells by western blot. c-Jun gene was knockdown by small interference RNA (siRNA) in JEG-3/MTXR cells, and LC3 was evaluated by western blot and reverse transcription-PCR. The binding of LC3 promoter with c-Jun protein was detected via chromatin immunoprecipitation assay (ChIP) with or without 0.02 ng/ml methotrexate exposure. Results The results showed that p-c-Jun was up-regulated after methotrexate treatment for 72 hours (1.99±0.20, versus 0.20±0.06 at 0 hour;P<0.05) by western blot analysis in JEG-3/MTXR cell lines. Further investigation demonstrated that c-Jun-siRNA could inhibit the up-regulation of LC3 formation and after methotrexate exposure (LC3 mRNA:1.24±0.17 versus 3.03±0.43;LC3 protein:0.52±0.07 verus 1.20± 0.15; all P<0.05). The binding of LC3 promoter by c-Jun protein was up-regulated after methotrexate treatment by the method of ChIP in methotrexate resistant JEG-3/MTXR cells [(2.95 ± 0.35) times]. Conclusion Autophagy-related gene LC3 expression regulated by c-Jun protein may be involved in the effect mechanism of the development of methotrexate resistance in choriocarcinoma JEG-3 cells.
