目的探讨超声在评估肝癌肝动脉栓塞术后肝硬变受损程度方面的价值.方法对43例原发性肝癌患者进行了肝动脉栓塞术前与术后临床肝功能检查及超声分析.结果多次肝动脉栓塞术后肝硬变程度加重,根据Child‘s分级肝功能下降率达67.4%,超声检查肝硬变加重率达70%.两者检查结果相一致.结论超声观察肝内回声的变化对评估多次肝癌肝动脉栓塞术后肝功能损害程度有重要作用. 相似文献

目的探讨系统呼吸功能锻炼指导光碟在食管癌患者围手术期的应用效果。方法将食管癌手术患者100例按入院时间分为对照组和实验组各50例。对照组采用传统方法进行呼吸功能锻炼,实验组采用系统呼吸功能锻炼指导光碟进行呼吸功能锻炼。观察两组患者呼吸功能锻炼的配合程度,术后2h、拔除气管插管当天及拔除气管插管后第2天肺部X线摄片情况。结果实验组患者呼吸功能锻炼配合程度显著优于对照组,术后拔除气管插管当天及第2天肺部X线摄片正常率显著高于对照组(均P0.05)。结论使用系统呼吸功能锻炼指导光碟对食管癌患者进行呼吸功能锻炼,更能保证锻炼的有效性,从而有效地减少肺部并发症的发生。 相似文献

BACKGROUND: The physiological environment of oral cavity is very complex. Dental restoration materials exposed to the weakly acidic body fluids in the long term, and were in the complex influences including physical, chemical, biological and mechanical and other factors. Therefore, the evaluation of biocompatibility for dental materials is the focus of research before entering the clinical trials, and also the important technical indicators to
ensure the clinical safety.
OBJECTIVE: To preliminarily evaluate the biocompatibility of ZrO2 and Al2O3 ceramic composites.
METHODS: The experiment was divided into six groups: ZrO2 and Al2O3 (1:1) 100% extract group, ZrO2 and Al2O3 (1:1) 50% extract group, ZrO2 and Al2O3 ( 4:1) 100% extract group, ZrO2 and Al2O3 (4:1) 50% extract group, and the volume fraction of 0.64% phenol positive control group and 100% fresh medium of negative control group. Acute hemolysis and in vitro cytotoxicity experiments were conducted according to the biological evaluation standards and requirements of GB-T16886 15-2003 medical devices. The effects of the above six groups of extracts on rabbit blood cells and L-929 mouse fibroblast cells were tested respectively.
RESULTS AND CONCLUSION: There was no significant difference in the absorbance values between different concentrations of experimental groups and negative control group (P > 0.05). The cytotoxicity rating of all experimental groups was 0-1 grade. The hemolysis rates in the ZrO2 and Al2O3 (1:1) 100% extract and ZrO2 and Al2O3 (4:1) 100% extract groups were 1.27% and 2.4% respectively, less than the accepted safety standards of 5%. These results demonstrate that the acute hemolytic experiment and in vitro cytotoxicity experiment of (1:1), (4:1) ZrO2 and Al2O3 ceramic composites are all negative, and all have good cytocompatibility and blood compatibility. 相似文献
