Objective To discuss the practice of nursing management model of stroke unit based upon the international standards implemented in the neurological unit.Methods The experiences of the stroke unit management were summarized and applied to instruct the clinical practice.Results After the implementation,the average hospitalization days,the proportion of drugs,medical cost,and mortality rate decreased.The satisfactory degree of patients with the stroke unit increased.Conclusions The nursing management model of stroke unit not only improved the quality of nursing service to stroke patients,but also decreases the mortality and disability rate,shortened the length of hospital stay,and enhanced the satisfaction degree of patients and their family members.

Objective To solve the three principal problems for reusing the software components, i.e., existence, discovery and availability principles, web services provided a new solution for reusing and assembling web software or components under distributed environment with a series of XML-based protocols. Methods A 4+1 meta-model between atomic services, such as Sequence, Parallelism, Alternation, Substitute and Iteration, and a kind of service composition description language in composition process are investigated. Furthermore, an architecture-based service composition model with Ontology Engine is proposed, which is based on the software architecture life-cycle model and provides a mechanism for services composition with dynamic management and deployment. Results The results of the prototype system development show that the service-composed application not only reused the web service components, but also reused the data resources located in distributed databases. Conclusion The method of reused-based web services composition observably decreases the period and cost of development and greatly improves the programming efficiency.

OBJECTIVE: To evaluate the therapeutic efficacy of transdermal fentanyl patches for moderate to severe cancer pain in aspects of pain control, quality of life, ADR, and etc. METHODS: Using the standard case report form combined with brief pain inventory (BPI) and numerical rating scale (NRS), 39 patients with moderate to severe cancer pain who received transdermal fentanyl (initial dose of 25 μg · h-1) for no less than five weeks were investigated. RESULTS: The total effective rate was 97.4% (38/39) and the average pain relief degree was 60.3%. All the patients gained significant improvement in multiple aspects of the quality of life. The main ADRs included constipation, dizziness, nausea, drowsiness, skin itch and etc, which were endurable, especially in the later therapeutic period. CONCLUSION: Transdermal fentanyl patches are the ideal alternative for patients with moderate to severe cancer pain. Copyright 2012 by the Chinese Pharmaceutical Association.

Objective To evaluate the role of the complement 1 q (C1 q) in hepatic ischemia-reperfusion (I/R) injury in rats.Methods Sixty healthy male Sprague-Dawley rats,aged 3-4 months,weighing 180-200 g,were randomized into 2 groups:sham operation group (S group,n =12) and hepatic I/R group (I/R group,n =48).Hepatic specimens were obtained at 1,3,6 and 24 h of reperfusion and were then cut and stained with haematoxylin and eosin for examination of histological changes of the liver (with light microscope) and for determination of superoxide dismutase (SOD) activity and malondialdehyde (MDA) content (by colorimetric method),expression of Clq mRNA (using real-time PCR) and expression of Clq (by using Western blot).Results Compared with S group,the activity of SOD was gradually decreased,the content of MDA was gradually increased,and the expression of Clq and Clq mRNA was gradually up-regulated and peaked at 3 h of reperfusion with the prolongation of reperfusion time in I/R group (P ＜ 0.05).The pathological changes of the liver were aggravated with the prolongation of reperfusion time in I/R group.Conclusion Activation of C1 q is involved in hepatic I/R injury in rats.

Objective:To explore the change of serum interleukin 16 (IL-16) level and the effects of highly-active antiretroviral therapy (HAART) on IL-16 in patients with HIV infection.Methods:77 patients with HIV infection were studied,with fifteen normal subjects studied as controls.The patients were subdivided into stages according to the standards by US Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO).Of all the individuals,the CD4+T cells and CD8+T cells and the amout of IL-16 were measured at each stage to find the difference among normal and groups of the patests,and between the groups with and without HAART.Results:The level of CD4+ T cells in the experimental group were lower than that of the control group in of the patients (P

Objective To study between serum uric acid and early morning blood pressure of the different degrees of Obstructive sleep apnea syndrome(OSAHS)patients.Methods134 cases of OSAHS were divided into mild,midrange and severe groups according to apnea-hypopnea index(AHI),and 23 healthy people as normal control group.serum uric acid and early morning blood pressure were measured among four groups.ResultsSerum uric acid levels in mild,midrange,severe OSAHS groups and the control group were(392.10?88.22)?mol/L,(460.14?118.86)?mol/L,(537.63?134.11)?mol/L,(304.36?80.12)?mol/L,there were significant differences among four groups.there were significant differences between severe OSAHS and the others in blood pressure,as well as between OSAHS midrange group and the control group.ConclusionSerum uric acid in OSAHS patients increased with increasing degree of AHI,the disorder of serum uric acid possiblly contribute to abnormal blood pressure in OSAHS patients.

TGR5,expressing in many tissue cells,is a kind of bile acid membrane receptor and participates in a variety of metabolic and immune diseases.Activated TGR5 can keep the metabolism system in a steady state by mediating the metabolism of bile acid,lipid,and blood sugar,reducing insulin resistance and increasing the body's energy consumption; TGR5 could regulate the immune responses of mononuclear cell and Kupffer cell in the liver.For example,it can regulate the adaptive immune response by inhibiting the expression and release of inflammatory cytokines in Kupffer cells,and regulating the differentiation and maturation of dendritic cells.This review mainly focused on the function of TGR5 in liver metabolism and immune and further explored the related mechanism,as well as its clinical significance in related liver diseases.

Objective To explore the application of PBL (Problem - Based learning) mode in fami-ly peritoneal dialysis training to improve the teaching effects of peritoneal dialysis training. Methods The PBL mode was applied in every peritoneal dialysis training lesson, the teaching effects were evalued af-ter a lesson immediately. Results The PBL mode would be helpful to inspire patients' and their family members' interest to learn the knowledge of peritoneal dialysis training.It was also helpful in knowledge un-derstanding, knowledge mastering and establishment of treatment confidence. Conclusions The PBL mode was an important way to improve the teaching effects of peritoneal dialysis training and realize the teaching objective. It is worth applying in practice of peritoneal dialysis training.
