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%.

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.

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

Objective To explore psychological resilience, anxiety, depression, coping styles and social supports status among parents of preterm infants of ophthalmic clinic, and analyze their relationship. Methods A total of 217 parents of preterm infants at ophthalmic clinic of hospital were selected by convenience sampling method and investigated by self- designed general information questionnaire, Connor-Davidson Resilience Scale, Self-rating Anxiety Scale, Self-rating Depression Scale, Social Support Rating Scale, and Simplified Coping Style Questionnaire. Results The total score of psychological resilience was (67.48 ± 14.20) points. The average score of positive coping styles dimension was (1.98±0.50) points, and negative coping style dimension score was (1.19±0.55) points. The social support score was moderate with a total score of (42.75 ± 6.17) points, the anxiety and depression got a total score of (36.77 ± 8.17) points and (39.67 ± 9.02) points respectively. Psychological resilience was negatively correlated with anxiety and depression (r=-0.363--0.242, P<0.01), and was positively correlated with coping styles and the social support (r=0.141-0.312, P<0.05 or 0.01). Multi-factor linear regression analysis showed that depression and social support were the influence factors of psychological resilience(t=-4.376, 2.516, P<0.01 or 0.05). Conclusions The parents of preterm infants are at the poor psychological states. Coping styles and depression are the important factors which affect psychological resilience among parents of preterm infants. Nurses should assess the psychological status of the parents, provide targeted interventions to relieve stress, guide the parents use social support effectively, and improve their psychological state.

A total of 160 elderly patients with Ⅰ -Ⅲ essential hypertension were enrolled in the study and examined with high-frequency color Doppler ultrasonography (America ATL Company HDI3500 type color ultrasonoscope). Common carotid artery (CCA), internal carotid artery and external carotid artery (ECA) were detected, including carotid artery intima-media thickness (CAIMT) and hemodynamic index. At the same time, 110 healthy elders were taken as contrast group. With the increased degree of hypertension, CAIMT was gradually enhanced and the most obviously in patients of grade Ⅲ hypertension. There were significant differences in grade Ⅲ, Ⅱ, Ⅰ and contrast group (P

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 chemiluminescences system is suitable for investigating the antioxidant activity of ginkgo albumin.
