1.Effects and Mechanism of Atherosclerosis Prevention by DMARDs in Patients with Rheumatoid Arthritis
Herald of Medicine 2014;(8):1012-1017
Objective To investigate the effect of DMARDs on the prevention of early-onset atherosclerosis in rheumatoid arthritis ( RA) patients for exploring an appropriate schedule to reduce cardiovascular events. Methods Seventy-two patients with early RA were included in this study. Erythrocyte sedimentation rate ( ESR) and high sensitivity C reactive protein ( hs-CRP) were detected before and after treatment to evaluate inflammation. Carotid intima-media thickness ( cIMT) and endothelium-dependent flow-mediated vasodilatation (ED-FMD) were monitored. Disease Activity Score in 28 Joints (DAS28) and health assessment questionnaire-disability index ( HAQ-DI) was used to assess severity degree of RA and life quality of the patients, respectively. The patients were treated with methotrexate (MTX), hydroxychloroquine (HCQ) and sulfasalazine (SSZ) alone or combined based on severity of RA. Results After 1 year of treatment, ESR, hs-CRP, DAS28 and HAQ-DI were significantly improved (all P<0. 01). At the same time, the serum lipid levels also had obvious changes. However, there was no obvious difference in body mass index ( BMI) after 1 year. The cIMT ratio value was significantly decreased compared to baseline (0. 43±0. 08 mm vs. 0. 50±0. 16 mm, P=0. 002), and FMD% also significantly improved from basic value of 5. 26 to 7. 57 after treatment (P=0. 041). Conclusion Early intervention of RA by using DMARDs can effectively control the disease and slow the progression of atherosclerosis, but also reduce cardiovascular mortality.

Chinese Journal of Practical Nursing 2015;(29):2225-2228
Objective To explore the prevalence of anxiety, depression, loneliness in elderly patients with long- term hospitalization, its coping style and the correlation between them. Methods 48 hospitalized elderly patients with long- term hospitalization were investigated by Standard Scale and self- administrated questionnaire, the Pearson's correlation was used to find the correlation. Results It was concluded that anxiety, depression and other negative emotions were commonly seen in elderly patients with long term hospitalization, these patients usually adopt the avoidance and yield coping style as well,and there was a positive correlation between them, the r value was 0.438, 1.473 amd 0.501 respectively. Conclusions This research confirmed the possibility of negative emotion in elderly patients with large long- term hospitalization, but also closely related to the choice of coping styles. The nursing staff should closely observe and assess the psychological status of elderly patients, planned, targeted to help elderly patients use more positive coping style.

Objective To explore the role of non-receptor tyrosine kinase(c-Src)in sevoflurane pretreatment for relieving myocardial ischemia-reperfusion injury.Methods By using the random number table,the healthy male Wistar rats were randomly divided into 5 groups (n=10):sham operation group (Ⅰ),ischemia-reperfusion group(Ⅱ),sevoflurane pretreatment group(Ⅲ), sevoflurane pretreatment plus dimethyl sulfoxide(DMSO,Ⅳ)and sevoflurane pretreatment plus c-Src specific inhibitor SU6656 group(Ⅴ)groups.The group Ⅲ,Ⅳ and Ⅴ were performed the sevoflurane aftertreatment before reperfusion;the group Ⅴ was in-jected by SU6656 at 5 min before reperfusion;the group Ⅳ was given the equal volume DMSO.The arterial blood sample in each group was collected at 120 min after reperfusion for detecting serum LDH level and CK-MB activity.Rats were killed for taking the heart and separating the left ventricle to calculate the area of myocardial infarctio;the expression levels of Src,phosphorylated Src (p-Src),CAT and SOD in myocardial tissue were detected in each group.Results Compared with the groupⅠ,the level of serum CK-MB and LDH activity,myocardial infarct area and p-Src/Src,CAT,SOD in the other 4 groups were increased significantly (P <0.05);comparing with the group Ⅲ,the serum CK-MB and LDH activity,myocardial infarct area and SOD,CAT,in the group Ⅱ,Ⅳ and Ⅴ were increased,however the level of p-Src/Src was decreased significantly (P <0.05).Conclusion The c-Src-reactive ox-ygen signaling pathway might mediate the role of sevoflurane pretreatment for reducing myocardial ischemia-reperfusion injury in rat.

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.
