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.

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

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.

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.

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 effects of eye movement desensitization and reprocessing (EMDR) versus cognitive behavior therapy (CBT) for treating adult posttraumatic stress disorder (PTSD) .Methods A total of 81 patients with PTSD con‐forming to the including standard were randomly allocated to the EMDR group ,CBT group ,and control group ,27 cases per group . The PTSD symptoms ,anxiety and depression moods in 3 groups were assessed before and after treatment by adopting the Clinician‐administered PTSD Scale (CAPS) ,Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD) .Results The drop‐out rates were 29 .63% for the EMDR group ,7 .41% for the CBT group and 7 .41% for the control group respectively ;the re‐experience symptoms score of CAPS in the EMDR group was lower than that in the CBT group with statistical difference (P=0 . 036) .Conclusion Both EMDR and CBT are the effective psychological therapeutic method ,EMDR has more effective than CBT in the reproving the re‐experience symptoms of PTSD .The future studies should pay more attention to the application of stabilization technologies for reducing the dropout rate of EMDR .

BACKGROUND: In our previous studies, zinc-calcium-phosphate (Zn-Ca-P) coating has been successful y prepared on the surface of AZ31 magnesium al oy, which improves the corrosion resistance of the al oy. OBJECTIVE: To analyze the hemocompatibility of Zn-Ca-P coated AZ31 magnesium al oy in vitro. METHODS: Zn-Ca-P coating was prepared on the surface of AZ31 magnesium al oy using chemical transformation. Afterwards, the characteristics of the Zn-Ca-P coating were investigated using scanning electron microscope, and X-ray diffraction analyzed its components. Besides, hemocompatibility in vitro was evaluated by platelet adhesion assay, dynamic clotting time test and hemolysis test. RESULTS AND CONCLUSION: Under scanning electron microscope, a flower-like coating was formed ont surface of the AZ31 magnesium al oy, with the main chemical component of insoluble phosphates Zn3(PO4)2?4H2O. And some round distortionless blood platelets adhered to the surface of AZ31 magnesium al oy, with no pseudopodia. In dynamic clotting time test, the long curve of Zn-Ca-P coating tended to descend indicating better anticoagulant activity. And the hemolysis rate was below 5%. In conclusion, Zn-Ca-P coating has good hemocompatibility in vitro.

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.

Objective To evaluate the effectiveness of biofeedback for anxiety patients by carrying out a Meta-analysis.Methods We searched CNKI,VIP,CBM(1989 to 2013) to identify relevant randomized-control trials applying biofeedback for anxiety patients.We used Review Management (RevMan) 5.0 software (provided by the Cochrane collaboration) to conduct Meta-analysis.Results We included 11 studies.Meta-analysis for the biofeedback group vs.the control group showed that biofeedback was significantly superior to control (SMD=-3.00,95％CI:-4.40～-1.61); Meta-analysis for the biofeedback plus drug group vs.drug group showed that biofeedback plus drug was significantly superior to drug (SMD=-1.33,95％CI:-1.82～-0.85).Conclusions We found evidence that biofeedback (applying alone or combined with drugs) is effective in improving anxiety symptom.But all the studies had methodological limitations,our conclusion needs further studies with strict design,high quality and consistent assessment tools to be expounded and proven.
