An integration of British healthcare and social services has been underway in recent years, and a typical methodology has been formed in the process of regional explorations . Using qualitative research methods of on-site observation and in-depth interviews, the paper studies the Care Programme Approach ( CPA) system of mental health and emergency multidisciplinary teams of Oxfordshire, a typical case of the integrated healthcare system re-forms in the British healthcare system. England’s integrated healthcare reforms have placed primary care and commu-nity health services at the center of the healthcare system and have included social services within the system. The ex-periences of multidisciplinary teams, integrated care pathways, personalized care planning and patient involvement and independence from the reforms are worthy subjects of study for China’s own healthcare delivery system reforms.

Molecular imprinted film modified glassy carbon electrode was prepared by electrochemical polymerization of pyrrole with the cyclic voltammetry in the presence of template molecular, salicylic acid. The template molecules were removed from the modified electrode surface by over-oxidized at 1.3V in the solution of 0.2 mol/L Na2HPO4 for 10 min. The modified electrodes can effectively promote electrochemical oxidation process of salicylic acid in the surface of electrode and avoid interference of structural similar substance such as benzoic acid. Cyclic voltammetry was employed in the electrochemical measurements. The experimental results show that the optimum acidity of background solution is pH 6.86 and the optimum incubation is 10 min. The linear response curve was obtained from 1.0×10-6 mol/L to 2.0×10-3 mol/L, with the detection limit of 8.0×10-7 mol/L. The imprinted electrode has been applied to the analysis of salicylic acid in the simulated samples with recovery rates ranging from 94.6% to 103.4%.

Although private hospitals are generally encountering development difficulties, some private non-profit medical institutions thrived in the medical market. These hospitals have rich experiences in terms of manage-ment system, operation mechanism, and competition methods. In this paper, we summarize the experiences of those well-functioning private non-profit hospitals and analyze the essential conditions for developing private non-profit med-ical institutions. These conditions include meeting local health market needs, ensuring that the hospital management system and operation mechanism result in high-quality health services, ensuring hospital development meets local health plans ( in order to obtain policy support) , ensuring the goal of the hospital is public welfare and that the hospital has strong financial support, obtaining certain social and political capital, and ensuring high-quality managers and staff.

In medical physiology experiment courses, the students observe the functions and learn the rules of biological body, in order to improve their abilities of scientific observation, practice and reflection. Emotion control means willpower to manage emotion, which is the regular psychological response when we deal with issues. Integrating the emotion control education to professional education is imperative to elevate the general quality of medical students.

Objective To investigate the impact of the gestational diabetes mellitus and abnormal glucose challenge test (GCT) on macrosomia. Methods Clinical data of 8656 pregnant women who had antenatal care and delivered in the Department of Obstetrics and Gynecology of the First Hospital of Peking University from Jan 1995 to Mar 2001 were retrospectively analyzed. All of them underwent 50 g GCT. Results The incidence of macrosomia was 8.1% (700/8656). The incidence of macrosomia in GDM or IGT women was 12.5%(69/552), which was significantly higher than that of other women with normal glucose level 7.8%(631/8104, P

BACKGROUND: Biological function of leukocyte-associated immunoglobulin like-receptor 1 (LAIR 1) has clearly researched in China and abroad, but the in vivo biological function of LAIR is poorly understood. OBJECTIVE: To establish LAIR-2 (CD306) eukaryotic expression vectors and to purify and identify the fusion protein. DESIGN, TIME AND SETTING: A single sample observation experiment was performed at the Fourth Military Medical University of Chinese PLA between June 2007 and June 2008.MATERIALS: plg/3c vector was offered by Oxford University, pcDNA3.1 vector was provided by Meyaard doctor. Chinese hamster ovary (CHO) cell lines were preserved by the Department of Immunology, Fourth Military Medical University of Chinese PLA.METHODS: Two eukaryotic expression vectors plg/3c-LAIR-2 and pcDNA3.1-LAIR-2 were constructed and were transfected into CHO cells. The binding activities of LAIR-2 fusion protein to LAIR-2 mAbs were identified by Western blot, immunocytochemistry and flow cytometry assay.MAIN OUTCOME MEASURES: The construction of stably transfected cell lines, and the purification and identification of fusion protein. The activity of LAIR 2 protein combined to corresponding monoclonal antibody.RESULTS: Eukaryotic expression vectors were constructed and trasnsfected into CHO cells successfully. Two cells lines CHO/LAIR-2-Fc and CHO/LAIR-2 that steadily expressed LAIR-2-Fc fusion protein and LAIR-2 protein were established. Western blot assay showed that LAIR-2 protein could bind specially to LAIR-2 mAb 1A7, 3H12 and 4A9. Immunocytochemistry and flow cytometry assay demonstrated that 3H12 and 4A9 could bind to LAIR-2 expressed in the transfected CHO cells. CONCLUSION: Two ceils lines CHO/LAIR-2-Fc and CHO/LAIR-2 were successfully constructed, which can transfected to CHO cells. The eukaryotic expressed LAIR-2 protein has good binding activity to LAIR-2 mAbs.

Objective To investigate the current status of nurses′ work performance and job involvement, and to analyze the impact of nurses′job involvement on work performance. Methods Self-made questionnaires were used to investigate 309 nurses in a 3A military hospital in Beijing. The military hospital is in a high standardization level, which may be properly representative of both military hospitals and 3A hospitals. Results The total score of nurses′work performance was 192.04 ± 31.25. The total score of nurses′ job involvement was 55.48 ± 9.94. The multiple regression analysis showed that the nurses′ work performance would be influenced by staff type, vigor and absorption. Conclusions The nurses′work performance and job involvement were at a high level. Managers should take methods to keep a high level of nurses′job involvement, which may improve work performance.

Objective To investigate the scavenging abilities of ginkgo albumin to reactive oxygen in vitro, as well as the protection and mechanism of ginkgo albumin on damaged DNA. Methods Lotus Seedpod Procyanidin (LSPC) and bovine serum albumin (BSA) were used as control sample, the effect of ginkgo albumin on removal of superoxide anion was determined by Pyrogallol-Luminol system. Scavenging ability of ginkgo albumin on hydroxide free radical was determined by CuSO4-Phen-Vc-H2O2, FeSO4-Luminol-H2O2, and FeSO4-Luminol systems. Luminol-H2O2 system was used to measure the scavenging effect on hydrogen peroxide. Preventive effect of ginkgo albumin on in vitro damaged DNA was determined by CuSO4-Phen-Vc-H2O2-DNA system. Results Ginkgo albumin possessed a good scavenging potency on reactive oxygen and protection on damaged DNA, but promoted oxidation in the FeSO4-Luminol-H2O2 and Luminol-H2O2 chemiluminescence systems. Conclusion Not every chemiluminescences system is suitable for investigating the antioxidant activity of ginkgo albumin.
