Objective To explore the application values of acoustic radiation force impulse imaging (ARFI) in predicting the staging of chronic kidney disease (CKD) and the degree of renal tissue fibrosis. Methods 48 CKD patients of different stages undergoing the examination of ARFI from March to December of 2016 were selected in the study and the pathological types of all the patients were confirmed as nephropathy by the pathological results. Those patients were divided into five stages from Stage 1 to Stage 5 according to the CKD clinical staging. In accordance with the standard of Estimated Glomerular Filtration Rate (eGFR)=60 mL·min-1·1.73m-2, those patients were also divided into the group with eGFR<60 mL·min-1·1.73m-2 and the group with eGFR≥60 mL·min-1·1.73m-2. The shear wave velocity (SWV) of renal cortex in each group was detected by ARFI and compared among different stages and groups. The Spearman correlation analysis was adopted to analyze the correlation of renal cortical elasticity of CKD patients with the indicators such as clinical stage, pathological fibrosis degree, serum creatinine, urea nitrogen, and kidney size respectively. The SWV differences of each group were analyzed by One-way ANOVA. Results The SWV value increased with the aggravation of CKD, and the SWV values of CKD Stage 4 and 5 were the highest and they were(2.51±0.50)m/s and(2.51±0.00)m/s respectively. The SWV value of the group with eGFR<60 mL·min-1·1.73m-2 was (2.29±0.40)m/s, while that of the group with eGFR≥60 mL·min-1·1.73m-2(2.30±0.40)m/s. The results of Spearman correlation analysis showed that the SWV values of renal cortex of CDK patients were not correlated with the indicators including the clinical stage of CKD, pathological fibrosis degree, serum creatinine, urea nitrogen, and kidney size (P>0.05). The results of One-way ANOVA showed that there were no significant differences in the SWV value among all the stages of CKD (P>0.05). Conclusion The SWV value increases with the aggravation of CKD, but it cannot be taken as the method to predict the clinical stage of CKD and the renal tissue fibrosis.

当看到体检报告中那些“不正常”时,有的人急忙上网查询相关信息,有的人到医院挂号看病,有的人甚至做好了住院的准备. 其实,有些体检结论不一定是“有情况”,可以先观察,不急着治疗.体检结论:宫颈糜烂处理意见:没症状可先不治 宫颈糜烂不能按字面去理解,因为它并非真正意义上的糜烂.

国务院于2009年3月17日提出<关于深化医药卫生体制改革的意见>,文中指出:"2020年前基本医疗保险制度全面覆盖城乡居民",实现全民享有健康的目标.解放军总部也适时提出"军队医院要积极参与地方社会医疗制度改革"的要求.医疗是军队密切军民关系的重要手段之一,我军医院从组建第一天起,始终把为地方群众医治疾病当作自己义不容辞的责任.而新医改政策的全面落实对军队医院的发展既是机遇也是考验,面临着诸多客观问题:譬如如何借势新医改促进军队医院的发展以提高军队医院服务保障水平,如何创建研究型现代战区总医院以实现军队医院的转型.本研究通过探讨军队医院目前面临的形势以及存在的不足,提出医疗市场营销在创建研究型现代战区医院中发挥的作用.
