彩色多普勒超声对糖尿病患者肾脏大小与肾血流动力学关系的分析 总被引:3,自引:0,他引:3
目的:应用彩色多普勒超声观察对糖尿病患者肾脏大小形态、结构及各级肾动脉阻力指数(RI)的改变,分析肾脏大小与阻力指数之间的关系,以期寻找更早期的、无创性的糖尿病肾病(DN)辅助诊断方法.方法:选择120例糖尿病(DM)患者,病程<5年为DM1组60例,病程>5年为DM2组60例,排除合并心衰、泌尿系感染、结石、肾血管疾病及其他原因致肾脏原发、继发病变,所有患者尿常规蛋白阴性,血尿素氮、肌酐正常.同时选择120例健康者作为对照组.应用彩色多普勒超声仪检查受试者肾脏大小、各级肾动脉阻力指数.应用SPSS统计软件包进行统计处理.结果:DN2组糖尿病患者肾脏较正常对照组及DM1组者大,两者比较有统计学意义.DM2组RI较DM1组及正常组高.DM2组肾脏大小与肾各级动脉RI之间有线性关系,呈正相关(r=0.85,P<0.05).结论:彩色多普勒超声(CDFI)检测能提示DM患者肾脏大小和肾血流动力学情况,对早期DN的诊断是有价值的. 相似文献

BACKGROUND: Directly percutaneous injection of protein-denaturant hydrochloric acid (PDHA) into tumors can lead to fast killing of tumor, sustained drug release and prevention of in situ recurrence of tumor. However, whether implants can be used combined with denaturant still remains unknown.
OBJECTIVE: To investigate the compatibility of fluorouracil implants and PDHA (6 mol/L).
DESIGN, TIME AND SETTING: Observational study was performed in the Hefei Industry University between October 2006 and March 2007.
MATERIALS: A total of 78 Wistar rats, weighing (200±20) g, half males and half females, were used for testing drug release in vivo. Drugs fluorouracil implants (H20030345; columniform particle, diameter 0.8 mm, length 4 mm; specifications: Fluorouracil 2 mg/particle; batch number: 20060922; meeting the National Drug Quality Standards [WS1-(X-103)-2005Z]) were provided by Wuhu Zhongren Pharmaceutical Company,Ltd. Hydrochloric acid (37%) was analytical reagent.
METHODS: 96 tubes of the implants and PDHA were kept at (37.0±0.5) ℃. Each time, six samples were collected at 1, 8, 16, 24, 96, 120, 168, 240, 360, 432, 480, 528, 600, 720, and 960 hours after incubation. Appearance of the implants was observed by microscope. Stability of fluorouracil in PDHA was determined by HPLC and ultraviolet absorb method. Based on the entering quantity and residual quantity of fluorouracil, the release rates were calculated.
MAIN OUTCOME MEASURES: The approximate solubility, stability and morphological change of fluorouracil in denaturant and the corresponding drug release character in both denaturant and rats in vivo.
RESULTS: At (37.0±0.5) ℃, the fluorouracil was stable for 960 hours in PDHA, the saturated concentration of fluorouracil was (22.72±0.04) g/L. The appearance of implants was intact. The surface was porous. Compared with the speed of releasing drug in rats, the speed of releasing drug was faster in the early stage of release process and slower in the later stage. The drug release was incomplete. At 1, 24, 96, 360 and 960 hours, the implants’ release rates were (11.9±6.7)%, (37.9±5.3)%, (52.6±4.5)%, (75.3±3.8)%, and (85.5±2.1)%, respectively.
CONCLUSION: The fluorouracil implants and hydrochloric acid (6 mol/L) are compatible and no influence is detected during the observation. 相似文献

目的:探讨产前超声检测不同病因致胎儿三尖瓣返流的程度,分析胎儿三尖瓣返流程度及其转归与病因的关系。方法:对2010年1月-2011年9月于本院行常规产前超声检查所发现的56例胎儿三尖瓣反流病例,根据综合检查情况分先心病组、非先心病组、单纯返流组,观察三组胎儿返流的程度、转归及其预后。结果:先心病组11例,非先心病组19例,单纯返流组26例,持续存在并加重8例,减少或消失的28例,无变化的20例。结论:病因与胎儿三尖瓣返流程度及转归有关,存在心内或心外病因的胎儿三尖瓣返流程度轻至重度,且转归多为持续存在或有加重,而单纯返流的胎儿三尖瓣返流程度多较轻,且转归可为减少或消失。 相似文献
