Objective To evaluate the effects of clinical pathway combined with transitional care implemented by specialty nurses on patients with coronary heart disease after PCI (percutaneous coronary intervention) therapy. Methods Totally 124 patients after PCI were divided into the experimental group and the control group with random digit table. Patients in the control group received routine education and follow- up during hospitalization and discharge period. The experimental group received clinical pathway combined with transitional care implemented by specialty nurses based on routine education. The level of patients′knowledge, attitude, practice and risk factors were compared between the two groups 6 and 12 months after discharge. Results There were 55 patients in each group completed the research ultimately. The Coronary Heart Disease Knowledge Questionnaire in the experimental group scored (57.61 ±8.77), (81.27±6.88) and (88.47±6.10),while the control group scored (59.71±7.32),(68.61±7.12) and (76.85±7.70), after repeated measurement analysis of variance, F=74.71, 14.52, P<0.01. The scores of General Self- Efficacy Scale (GSES) and Coronary Artery Disease Self- Efficacy Scale (CSMS) between two groups at three time points showed statistical significance, F=5.40, 14.52, P<0.05 or 0.01. The risk factors of coronary heart disease such as total cholesterol, triacylglycerol, hemoglobin A1c, body mass index, systolic pressure and diastolic pressure were statistically different between two groups except for high density lipoprotein cholesterol and low density lipoprotein cholesterol, F=5.82, 20.32, 4.14, 4.15, 4.99, 7.15, P<0.05 or 0.01. Conclusions Clinical pathway combined with transitional care implemented by specialty nurses can improve the knowledge-attitude- practice level of patients, help to control the risk factors of coronary heart disease. It is an effective heart rehabilitation model for patients after PCI.

The fragmentation pathways of two taxanes drugs have been studied in positive ion mode by Q-TOF with the advantages of high mass accuracy and high resolution analysis. The [M+H] + ions were observed by ESI-MS, from which the molecular weights were obtained. Using the protonated pseudo-molecular ions [M+H]+ as internal reference compounds, the accurate mass and element composition of the fragment ions were determined. The collision induced dissociation (CID) data of the [M+H] ions provided fragmentation pathways of related compounds. Results showed that the major cleavage pathways of paclitaxel and docetaxel were the same that the cleavage of C-O bond between the side chain and taxol skeleton easily occurred, then stripping of the functional groups on the parent ring. Some common fragments were formed, such as m/z 105.033 7, 291.137 3, 309.148 5, 327.159 7, 387.181 2 and 509.217 4, which would provide a basis for future qualitative and quantitative analysis of taxanes in vitro and in vivo.

OBJECTIVETo explore the possibility of applying the concept of various stages of dietary behavior changes in Hangzhou residents.

METHODSThe dietary behavior was surveyed and analyzed in 1 388 Hangzhou residents with 18 year-old and older using the various dietary behavior change model model and stages of change.

RESULTSThe proportion of Hangzhou residents with unhealthy dietary behavior was high and associated with gender and education level. The changes of dietary behavior could be divided into 5 stages, i.e. preintention, intention, preparation, action and maintenance. These stages of change happen consecutively. The changes of unhealthy dietary behavior do not match the improvement of health knowledge. Although a significant proportion of the residents understand that it is unhealthy to eat too much fat, pickles and high salt food, there are only a few of them really take action to reduce the consumption of these foods and to consume more milk, fruit and vegetable.

CONCLUSIONSThere are multiple factors that affect the changes of dietary behavior in people. The changes of dietary behavior occur in various consecutive stages. Different intervention measures should be applied to people in different dietary behavior changes.

Objective To investigate the incidence,pathogenetic factors,prognosis and correlation factors of acute kidney injury(AKI) in the hospitalized elderly patients. Methods The clinical data of 4781 elderly patients (aged 65 years and over) in our hospital from June 2008 to December 2009 were collected in this study using the hospital information system(HIS).The patients with AKI were picked out and were retrospectively analyzed. Results Among 4781patients,515cases (10.8％) suffered from AKI and the incidence of AKI increased with growing age. Single factorial analysis of etiology showed that infections (39.2％) was the most common causes of AKI.Multifactorial analysis revealed that the major causes of AKI were infections (81.0％),followed by hypovolemia (67.2 ％ ),nephrotoxic drugs (64.1％ ),cardiovascular diseases (32.3 ％),respiratory failure(17.7％) and neoplasm (9.5％). Multivariate logistic analysis and cox proportional hazard models indicated multiple organ dysfunction syndrome(MODS),gastrointestinal bleeding,mechanical ventilation and malnutrition were independent risk factors inducing end events such as dialysis or death and influencing time of live. Conclusions There is high incidence of AKI in the elderly hospitalized patient.Infections,hypovolemia,nephrotoxic drugs and cardiovascular diseases are the common causes of AKI.Active treatment of primary diseases,early diagnosis and prevention are beneficial for improving the prognosis of AKI.

BACKGROUND: The quality of treatment for critically ill children varies widely at different hospitals. This study aimed to analyze the characteristics of mortality in a pediatric emergency department (PED) at a tertiary children's hospital in Guangzhou, China and to investigate the risk factors associated with the mortality. METHODS: The mortality of pediatric patients at the hospital from 2011 to 2013 was retrospectively analyzed using descriptive statistics. RESULTS: Altogether 466919 patients visited the PED during the period and 43925 of them were admitted for further observation. In 230 deaths, the ratio of boys to girls was 1.4:1, and their age ranged from 2 hours to 16 years (median, 5 months). The time from admission to death ranged from 0 to 216 hours (median, 1.5 hours). There were 92 (40％) patients who died within 24 hours after admission and 104 (45.2％) patients who died on arrival. The prominent causes of the deaths were respiratory diseases, neuromuscular disorders, cardiovascular diseases, and sepsis, most of which were ascribed to severe infection. Sixty-five deaths were associated with more than one concomitant problem. The top concomitant problems were congenital malformation, low gestational age, and severe birth asphyxia. CONCLUSIONS: In our center, 40％ of the patients in the PED died of fatal acute diseases, and pneumonia was the first leading cause of the deaths. Almost half of the deaths occurred on arrival and the rest were due to end-stage malignant diseases. This study emphasized the importance of prevention of birth deficits by reducing deaths in infants and children.

OBJECTIVETo investigate the effect of beta-catenin on the activation of hepatic fibrosis by transforming growth factor-beta 1 (TGFbeta1).

METHODSThe recombinant expression plasmids pcDNA3.1(+)-beta-catenin and pEGFP-N1 were cotransfected into cultured HSC-T6 cells. The expression of smad3, beta-catenin and alpha-SMA, beta-catenin protein in TGFbeta1 treated HSC-T6 cells were detected by RT-PCR and Western-blot.

RESULTSThe expression of smad3 and beta-catenin in the co-transfected cells was higher than that in the untransfected cells (smad3 mRNA were 0.642 +/- 0.011, 0.501 +/- 0.021, 0.511 +/- 0.019, 0.356 +/- 0.017, respectively, F = 135.304, P < than 0.05. beta-catenin mRNA were 0.783 +/- 0.021, 0.543 +/- 0.033, 0.538 +/- 0.024, 0.212 +/- 0.019, respectively, F = 267.340, P < than 0.05. smad3 protein were 0.892 +/- 0.012, 0.124 +/- 0.011, 0.130 +/- 0.021, 0.003 +/- 0.001, F = 2823.813, P < l than 0.05. beta-catenin protein were 0.921 +/- 0.020, 0.210 +/- 0.010, 0.208 +/- 0.008, 0.002 +/- 0.001, respectively, F = 3440.982, P < than 0.05). The expression of beta-catenin and smad3 protein had a positive correlation with the level of alpha-SMA protein in cells (r = 0.901, P < than 0.01; r = 0.939, P < than 0.01).

CONCLUSIONSExpression of smad3/alpha-SMA/beta-catenin is increased in the cultured HSC-T6 cells transfected by beta-catenin gene, especially when the transfected cells are stimulated by TGFbeta1. Our data suggest that beta-catenin could aggravate hepatic fibrosis induced by TGFbeta1.
