Objective To understand the present situation of safety organizing and quality of nurse work life in pediatric intensive care unit(PICU),and to discuss the relationship between safety organizing and quality of nurse work life.Methods A total of 279 PICU nurses in eight hospitals in Zhejiang were selected by the safety organizing scale (SOS)and quality of nursing work life(QNWL).Results The score of SOS was (45.23 ±10.88)points,and the score of QNWL was (159.46 ±33.60)points.There was a positive correlation between safety organizing and quality of nurse work life(r =0.256,P <0.05).Conclusion The nurse managers should improve the level of quality of nurse work life by safety organizing.

Objective To investigate the feasibility of high?resolution microendoscopy( HRME) im?aging for animal gastrointestinal mucosa. Methods Mucosal tissues were harvested from the stomach, small intestine, and large intestine of Japanese big?ear white rabbits. The effects of HRME imaging of different lo?cations such as the gastric antrum and fundus, small intestine and large intestine were observed, and those of different exposure time were compared.Accuracy of HRME imaging was compared with pathology. Results The specific tissues of the gastrointestinal mucosa could be clearly distinguished from the HRME images. In the superficial layer of the fundic mucosa, numerous closely arranged glands as well as oval or elongated branched openings of the gastric pits and linear peripheral cracks were visible;the nuclei were arranged reg?ularly. In the superficial layer of the antral mucosa, irregular or tubular openings of the gastric pits and cracked glandular cavities were visible, with the cells surrounding the gastric pits regularly arranged and the nuclei small and densely distributed. In the superficial layer of the small intestine mucosa, stereoscopic thick?finger?shaped villi cluster was visible. The intervillous spaces were crack?like, and the surface was cov?ered by regularly arranged reflective, absorptive cells. In the superficial layer of the large intestine mucosa, many regularly arranged daisy?like round crypts of uniform size, as well as reflective, goblet cells surrounding the crypt and the interval space between crypts were visible. When the exposure time increased, the nuclei became brighter. An excellent correlation was noted between the results of histologic examination and those obtained by using HRME. Conclusion HRME can produce accurate images of the animal gastro?intestinal mucosae and may be a novel technique for further studies of human gastrointestinal pathology.

AIM: To investigate the autophagy of breast cancer cells induced by baicalein and to explore its mechanism.METHODS: The effects of baicalein on the viability of MCF-7 cells and 4T1 cells were investigated by MTT assay, and the dosage of the drug was determined.The expression levels of microtubule-associated protein 1 light chain 3-II (LC3-II) and LC3-I in the MCF-7 cells and 4T1 cells treated with baicalein at doses of 25, 50 and 100 μmol/L, or combined with autophagy inhibitor 3-methyladenine (3-MA) were determined by Western blot.In order to confirm the role of baicalein in autophagy, the effect of 3-MA on the apoptosis of both MCF-7 cells and 4T1 cells induced by baicalein was analyzed by flow cytometry.The protein levels of p-mTOR, mTOR, p-AKT and AKT were examined by Western blot and the role of AKT-mTOR pathway in the induction of autophagy in breast cancer induced by baicalein was determined by the combination of activators.RESULTS: Baicalein at 50 μmol/L and above doses significantly inhibited the viability of breast cancer cells in a dose-and time-dependent manner.The expression of LC3-II/LC3-I in both MCF-7 cells and 4T1 cells was significantly enhanced after the action of baicalein, and the ratio of LC3-II/LC3-I was significantly decreased after 3-MA addition.The results of flow cytometry showed that, compared with baicalein group, the combination of baicalein and 3-MA promoted the levels of necrosis and apoptosis.Moreover, the protein levels of p-mTOR and p-AKT were significantly decreased and were rescued by EGF, while their total protein levels were not changed.CONCLUSION: Baicalein induces autophagy through AKT-mTOR pathway both in MCF-7 cells and 4T1 cells.

Objective To summarize the picture features of high resolution micro-endoscopy (HRME) for normal gastrointestinal mucosa. Methods We select 10 cases' normal esophageal mucosa, gastric and duodenal mucosa, in-testinal mucosa and colonic mucosal biopsies for this study, use HRME to observe the specimens and describe the features of different parts of the digestive tract normal mucosa according to the collected HRME pictures. Results After HRME imaging, all specimens were sent to pathological examination. We obtained 1 284 HRME pictures for 50 cases of biopsy specimens, 400 pictures were selected for results analysis after screening. HRME image charac-teristics of different parts of the digestive tract normal mucosa are as follows. Esophageal mucosa: cell arrangement rules, round and bright nucleus, the same size, nuclear spacing normal, the number of cells per field in basically are the same. Fundic mucosa: numerous closely arranged glands as well as oval or elongated branched openings of the gastric pits and linear peripheral cracks were visible; the nuclei were arranged regularly. Antral mucosa: irregular or tubular openings of the gastric pits and cracked glandular cavities were visible, with the cells surrounding the gastric pits regularly arranged and the nuclei small and densely distributed. Duodenal mucosa:visible villi was large fingers,on both sides of lint jagged depression, stereoscopic obviously, a cluster-like arrangement and the gap was crack-like. Intestinal mucosa:villous structures wider gap is wider, less than the number of the duodenum. Colonic mucosa:the nucleus of the same size, shape rules, round or oval and daisy-like glandular structures. All specimens were confirmed normal mucosa by pathology. Conclusion HRME can accurately identify the different parts of the diges-tive tract normal mucosa and it has a high consistency compared with pathological results.

High Resolution Microendoscopy (HRME) is a new imaging method which based on high resolution fiber and molecular imaging technology and it is possible to organize real-time imaging. After design and optimization of excitation light conduction part, fluorescent image transfer unit, optical fast switching unit and image capture unit, we constructe a HRME imaging system. We make an imaging observation of animal gastrointestinal tract by using HRME system and the results show that the feasibility of virtual pathology of HRME which lay the foundation for further clinical research. As an instant histopathological imaging method, HRME is expected to become a new immediate diagnosis model.
