Objective To discuss cultivation of higher vocational nursing talents in the model of learning and working rotation during the cooperation of school and hospital. Methods Students were cultivated by two years school study, two years learning and hospital work rotation and one year hospital position practice which was adopted as an "221" mode by means of organizational leadership,agreed safeguard and co-management. Half day learning and half day practice in four learning situation which have been transformed from the real professional workplace. Results Scores of professional core courses and operation skills had been improved significantly; Students cultivated by "221" mode had more superiority on the aspects of post adaptability, hand skills, communication skills and the ability of linking theory to practice. Conclusions The model of learning and working rotation during the cooperation of school and hospital is the important way of cultivating higher vocational nursing talents.

Objective To detecte the pathogenetic mechanism of cortical deficit in persons with strabismic amblyopia by blood oxygenation level dependent-functional magnetic resonance imaging (BOLD-fMRI). Methods The data of BOLD-fMRI of occipital visual cortex in 11 persons with strabismic amblyopia and 8 healthy ones were collected by 1.5T MRI system. The results of binocular pixel exponent in strabismic amblyopia group was compared with that in the normal group and the result of and average activation of cortical neuron in strabismic amblyopia group was analyzed. Results The binocular pixel exponent was lower in the strabismic amblyopia group (14.13%?4.55%) than that in the normal group(47.82%?5.34%) ( P

Objective:To establish an ICP-MS method to determine the contents, extraction and migration of Mg and Al in poly-propylene infusion bottles. Methods:An ignition pretreatment method was adopted to determine the contents of Mg and Al in the mate-rials. Five different extraction media with extreme extraction were used to extract and test Mg and Al in polypropylene infusion bottles. Three injections commonly used in clinics were put into polypropylene infusion bottles to carry out accelerated experiment, and the con-tents of Mg and Al were determined by ICP-MS. Results:Mg and Al both had a good linear relationship within the range of 0. 025-1. 0μg·ml-1 (r =0.999 8 and 0.999 0). The recoveries for polypropylene infusion bottles and extraction and migration test were 93. 77%-105. 0% and 96. 53%-103. 89% with RSD of 0. 4%-6. 9% and 1. 0%-7. 1%(n=9), respectively. Conclusion:The meth-od is accurate, sensitive and simple, which can provide reference for the safety data of polypropylene infusion bottles.

As the development of hospital information systems in the third-tier hospitals of the first grade in China gradually deepens, there has appeared an urgent need to formulate standards for the management of such systems. The paper offers proposals for the structure, composition and main responsibilities of the centers for hospital information management, posts setting and post responsibilities in the centers, the number of allocated personnel in the centers and the number of personnel required for various posts, and management standards and operating procedures in the centers.

Oral imaging techniques have been widely and increasingly used in clinical practice.This article reviews the functions,characteristics and principles of three kinds of oral imaging instruments including panoramic x-ray unit,intraoral x-ray unit and stomatology endoscope.

Objective To investigate the expression of eukaryotic initiation factor 4E(eIF4E) ,vascular endothelial growth factor (VEGF)‐A and VEGF‐C in gastric cancer tissues and their correlation with invasion and metastasis of gastric carcinoma .Methods The expressions of eIF4E ,VEGF‐A and VEGF‐C were detected in tissues of 58 gastric carcinomas and 25 normal gastric mucosa by using immunohistochemical method .Results The positive rate of eIF4E、VEGF‐A and VEGF‐C protein expression were 89 .7%(52/58) ,65 .5% (38/58) ,60 .3% (35/58) in gastric carcinoma ,which were higher than those in normal gastric mucosa tissues which were 4 .0% (1/25) ,12 .0% (3/25) ,8 .0% (2/25) respectively .Expressions of eIF4E ,VEGF‐A and VEGF‐C were significantly correlated with the depth of invasion and lymph node metastasis(P<0 .05) ,but not with the age ,sex of patients(P>0 .05) .Ex‐pressions of eIF4E and VEGF‐C were significantly correlated with tumor differentiation .The expression of eIF4E was being found positively correlated with VEGF‐A and VEGF‐C .Conclusion eIF4E may play certain roles in the oncogenesis and progression of gastric carcinoma .VEGF‐A and VEGF‐C may be helpful in lymph metastasis .Combined detection of eIF4E ,VEGF‐A and VEGF‐C may be helpful to assess the malignant degree and prognosis of gastric carcinoma .

Objective To investigate the levels and the abnormal incidences of apolipoprotein and other related indicators in health people in Hunan province,and to provide data for establishment of reference intervals in Hunan province.Methods The people with physical examination (n =341) were chosen from the Second Xiangya Hospital of Central South University during August 2014 ～ October 2014 (male,n =239;female,n =102) with age from 22 to 77 years old.All people were divided into 4 groups according to their age:group A aged from 22 to 42 (35.56 ± 5.39),group B aged from 43 to 48 (45.59 ± 1.59),group C aged from 49 to 55 (51.19 ± 1.81),and group D aged from 56 to 77 (63.08 ±5.84).The levels of apoAI,apoB,Lp (a),hypersensitive C-reactive protein (hs-CRP),and homocysteine (HCY) were detected with automatic biochemical analyzer,and were compared among different age groups and between male and female in each age group.Results Compared to male,the average levels of apoAI,and Lp (a) were significantly increased (P ＜0.05),and apoB,hs-CRP,and Hcy were significantly decreased (P ＜ 0.05) in the female.The levels of apoB,and hs-CRP were significantly different among 4 age groups (P ＜ 0.05).The abnormal rate in each index among 4 age groups was not significantly different (P ＞ 0.05).For groups A,B and D,the abnormal rate of Hcy was significant higher in male relative to female (P ＜ 0.05).Conclusions All the indices have significant difference between male and female (P ＜0.05).The levels of apoAI,Lp (a),hs-CRP,and Hcy do not change with the changed age.However,apoB has a certain relationship with age.The level and abnormal rate of Hcy are significantly higher in male relative to female.
