ABSTRACT
Objective To explore the theory of curriculum contents for gerontological nurse practitioner training which is suitable for the situation of our country. Method Delphi technique was used in this research to build content indicators of gerontological nurse practitioner training curricu-lum, and calculate the variation coefficient. Results The theory training curriculum includes founda-tions of gerontological nursing, geriatric syndrome, facilitating physiological balance and general gero-tological care modules and 41 core indexs. Every coefficient of variation is less than 20 percent [(4.35±0.71), (4.63±0.57), (4.55±0.57), (4.67±0.55)]. The mean values of the importance (4.54± 0.622) and general characteristics are more than four. Conclusion The content setting of the geron-tological nurse practitioner training theory course not only highlights the training characteristics of the geriatric care, but also has comprehensive and systematic content, reflects humanistic care spirit and pays attention to developing nurses’clinical practice ability. Therefore, it is worthy of reference and promotion.

Participants were satisfied with the workshop mode . Conclusion Application of workshop in tralning program can improve nurses' knowledge of fall-prevention and guarantee patient safety.
ABSTRACT
Objective Toinvestigatetheriskfactorsforleukoaraiosis(LA)inpatientswithlarge arteryatherosclerosis(LAA).Methods Theclinicaldata(age,sex,hypertension,diabetes,smoking, serum lipid level,hyperhomocysteinemia,and numbers of stenosis or occluded cerebral arteries)of 312 patients with LAA classified by the modified stop stroke study trial of Org 10172 in acute stroke treatment (SSS-TOAST ) were analyzed retrospectively. The age-related white matter changes (age related white matter changes,ARWMC)scale was used to evaluate LA. All the 312 patients were divided into non-LA group(n=72)and LA group(n=240)according the T2 weighted magnetic resonance imaging (MRI) and fluid attenuated inversion recovery(FLAIR)sequence,and 3 groups according to the (age-related white matter changes,ARWMC)scores:mild LA,moderate LA,and severe LA groups. The patients with multiple risk factors were analyzed by the univariate and multivariate Logistic regression analyses. Results (1)Of the 312 patients with LA,227 were males (72. 8%). Their average age was 64 ± 11 years,and 240 of them (76. 9%)had LA. Multivariate Logistic regression analysis showed that age (OR,2. 911,95%CI 1. 647-5.146,P=0. 000),hypertension (OR,2. 583,95%CI 1. 373-4.857,P<0. 01),diabetes (OR,1. 882, 95%CI 1. 058-3. 348,P <0. 05),the numbers of stenosis or occlusion arteries (OR,1. 851,95%CI 1.018-3. 367,P<0. 05),and lacunar infarction (LI)(OR,1.493,95%CI 1. 202-1. 853,P<0. 01)were the risk factors for LA. (2)The comparison of the clinical data in patients with different severity in the LA group found that there were significant differences in age,hypertension,diabetes,the numbers of stenosis or occlusionarteries,andLIamongthe3groups(allP<0.05).Conclusion Age,hypertension,diabetes, the numbers of stenosis or occlusion arteries,and LI are the independent risk factors for patients with LAA,and it is associated with the severity of LA.
ABSTRACT
Objective To assess the enhancement feature of intracranial atherosclerotic plaque in the vessel supplying the territory of infarction by using high-resolution MR imaging.To analyze the correlation between the degree of plaque enhancement , time elapsed and the concentration of hypersensitive C-reactive protein ( hs-CRP ).Methods The characteristics of vessel walls and intracranial vascular stenoses were retrospectively analyzed in 81 patients with ischemic strokes.All subjects were imaged with a traditional stroke MR protocol and HR-MRI scanning for plaque on a 3.0 T MRI scanner.According to the elapsed time between infarct and MR examination , all cases were classified into early stage (12 weeks, n=10).The characteristics of vessel walls and degrees of enhancement of atherosclerotic plaques were assessed and the concentrations of hs-CRP in all patients were determined.The Kruskal-Wallis H test was used to compare the degree of enhancement and hs-CRP concentration among the early , middle and late stage.The concentration of hs-CRP was presented as median ( interquartile range ).The Spearman correlation was used to analyze the correlation between elapsed time , hs-CRP concentration and degree of enhancement.Results Fifty-five (55/81) plaques were located at the M1 segments, and the other 26 (26/81) plaques were at the basilar artery.The degree and presence of enhancement from strong to none were 29, 25 and 4 in the early stage;4, 6 and 3 in the middle stage and 0, 4, 6 in the late stage, respectively.The degree and presence of enhancement were significantly different among them (H=16.934,P<0.01).There was a remarkable trend of decreasing degree and presence of enhancement of the atherosclerotic plaque relative to increasing time after the ischemic event(r=-0.792,P<0.01).The serum hs-CRP concentration for early, middle and late stage were 7.0(3.0, 13.0), 2.27(1.0, 3.03) and 1.88(0.50, 4.0)mg/L (H=14.345,P<0.01) , respectively.There was a trend of decreasing hs-CRP concentration relative to the time elapsed ( r =-0.357,P<0.01).The degrees of enhancement of the plaques were parallel to the levels of hs -CRP( r=0.526,P<0.01).Conclusions Enhanced HR-MRI scanning may clearly demonstrate the enhancement characteristics of intracranial atherosclerotic plaques as an indicator of inflammation.It might play an important role to detect risk factors for intracranial plaque rupture and subsequent acute ischemic stroke .
ABSTRACT
The curative efficacy of percutaneous transluminal angioplasty and stenting (PTAS) in the treatment of patients with ischemia cerebrovascular disease caused by artery stenosis was explored. The clinical data of 111 patients with ischemia cerebrovascular disease receiving PTAS in Guangdong Province General Hospital from Aug. 2007 to Nov. 2009 were retrospectively analyzed. In total 132 stents were implanted in the 111 patients. The mortality and rate of neural and non-neural complications were assessed perioperatively. Outcomes [including the frequency of transient ischemic attack (TIA), stroke, or death from vascular diseases) were assessed after operation. NIHSS rating was performed in all cases before and at first week, 6th month and 12th month after the operation. The PTAS success rate was 100%. The degree of stenosis was reduced after PTAS. The total complication rate during perioperative period was 15.3% (the rate of neural complications was 3.6%). Sixty-seven patients were followed up. Three patients (4.48%) developed cerebrovascular events within 1 month, containing one case of TIA, one case of ipsilateral mild stroke and one case of contralateral mild stroke. No severe stroke or death was observed. During a follow-up period of 12 months 7 patients had cerebrovascular events (10.44%), including 2 cases of ipsilateral TIA (2.99%), 2 cases of ipsilateral mild stroke and 2 cases of contralateral mild stroke (2.99%), one case of severe stroke (1.49%). In 13 patients receiving DSA re-examination one year after PTAS, 2 patients (15.38%) had in-stent restenosis. NIHSS scores were obviously decreased during a follow-up period as compared with those pre-operation (P<0.05). It was concluded that PTAS could significantly alleviate the neural function deficit of the patients with ischemia cerebrovascular disease. The success rate of PTAS was high, and the rate of complications was lower and the clinical outcomes were satisfactory. PTAS is a safe and effective therapeutic method, though the long-term outcomes need further study.
ABSTRACT
Objective To investigate the typical value of gamma-radiation dose rate and its confidence interval in tank-transported copper ore by using bootstrap resampling techniques. Methods Bootstrap resampling method, coupled with kernel density estimation, introduced to acquire the typical value of gamma-radiation dose rate in copper ore. Results The typical value of gamma-radiation dose rate in copper ore was expressed as the central tendency of the means of resampling, and two kinds of confidence interval, empirical percentile and bias-corrected accelerated confidence interval, were provided as standard error. Conclusion It is clearly demonstrated that this method has an advantage to give a robust description in explanation of central tendency and variation range of gamma-radiation dose rate data profiles.
ABSTRACT
Objective To observe the prognostic factors of functional outcome of patients with cerebral infraction treated in stroke unit.Methods The data of patients with cerebral infractions treated in stroke unit in our hospital were prospectively collected from April 2004 to December 2005 continuously.All the patients They were fol lowed up either by their regular visits to our outpatient clinics or by phone interview.The modified Rankin scale(mRS)score was used as the index of primary outcome.The prognostic factors of the functional outcome were analyzed by monovariate and multivariate logistic regression.Results A total of 150 cases were collected,of whom 98 were with good outcome,52 cases with poor outcome.The multivariate logistic regression showed that the poor outcome was associated with aging,previous history of stroke,high NIHSS scores,complications,and time from onset of the disease to admission to stroke unit.Conclusion The results suggested that older age,having stroke history,higher NIHSS total scores,having complications and delayed hospitalized time were influence factors to functional outcome of cerebral infractions in stroke unit.
