Objective To explore the accuracy of CT examination in the diagnosis of urinary stone composition.Methods 205 patients with urinary stone admitted from February 2009 to January 2011 were given non-enhanced spiral CT examination and the results were compared with those of infrared spectrometry,which was the golden standard.The area under ROC curve and the accuracy indicators of stone composition were used to evaluate the accuracy.Results According to the area under ROC curve,the optimal threshold(CT value) for the diagnosis of stone composition were: urine ammonium 231 HU,anhydrous uric acid 244 HU,carbonated apatite 862 HU,calcium oxalate monohydrate 640 HU,calcium oxalate dihydrate 675 HU,uric acid dihydrate 281 HU,calcium hydrogen phosphate dihydrate 1 567 HU,and magnesium ammonium phosphate hexahydrate 231 HU.Compared with the randomly acquired area 0.50,the areas under ROC of carbonated apatite,urine ammonium and anhydrous uric acid showed statistically significant differences(P0.05),but the areas under ROC of uric acid dihydrate,calcium hydrogen phosphate dihydrate and magnesium ammonium phosphate hexahydrate showed no statistically significant difference(P0.05).The accuracy and specificity of CT examination in the diagnosis of carbonated apatite,calcium oxalate monohydrate and calcium oxalate dihydrate were 71.4% and 67.2%,81.5% and 48.8% and 53.6% and 46.3% respectively.Conclusion The accuracy of CT examination is high in the diagnosis of carbonated apatite and calcium oxalate monohydrate,but the accuracy for other components is uncertain.The combination with other methods,like the analysis of urine metabolites,can increase accuracy.
目的:评价脑梗死后吞咽障碍患者行逐痰祛瘀汤、针电刺激联合治疗临床效果、对吞咽功能改善作用.方法:选择接诊脑梗死后合并吞咽障碍患者72例开展对比性治疗研究,治疗时间段为2017年6月～2021年6月,以中心随机系统分组原则设置组别后,参照组(35例)接受常规康复治疗,试验组(37例)接受康复治疗+逐痰祛瘀汤+针电刺激治疗.评价患者治疗吞咽障碍改善率,吞咽功能分级占比,吞咽障碍相关不良预后发生率,吞咽功能评分、神经功能损伤评分、生活质量评分及中医证候积分组间差异.结果:(1)治疗后,试验组吞咽障碍改善率(10
目的:分析自体动静脉内瘘(AVF)狭窄中超声引导下经皮球囊扩张血管成形术(PTA)治疗方案应用价值.方法:本项研究于2020年1月正式启动,截止时间是2023年1月.选用此时间段到我院接受诊治的AVF狭窄患者80例为研究对象,并基于完全数字随机表法分为对照组与研究组,分别接受外科手术治疗与PTA治疗.对比观察治疗前后内瘘狭窄改善情况、并发症发生率、术后随访观察AVF内瘘通畅率数据改变.结果:同治疗前相比,两组治疗后AVF狭窄处内径增加,阻力指数降低,肱动脉血流量、泵控血流量、内瘘自然流量升高,横断面积增加
目的:探究个性化护理在老年冠心病患者心绞痛治疗中的临床应用效果.方法:选2020.11至2022.11期间我院收治92例老年冠心病心绞痛患者为研究样本,随机分成对照组(常规护理)和观察组(个性化护理),各46例.比对两组临床应用效果.结果:观察组SAQ评分比对照组高,SAS、SDS评分比对照组低,WHO-QOL-BREF评分比对照组高,不良事件发生率比对照组低,护理满意度比对照组高(P<0.05).结论:个性化护理用于老年冠心病心绞痛患者护理中效果优良,能改善患者心绞痛症状与生活质量,并能减轻负面情绪,减
目的:分析喉癌切除术后并发咽瘘的原因,探讨优质护理的价值.方法:研究对象为37例喉癌及下咽癌患者,通过对其临床资料的回顾分析,整合术后并发咽瘘的原因,并探讨给予优质护理后患者不良情绪、睡眠质量、咽瘘发生率的改善情况,研究起止时间为2021年10月-2022年10月.结果:喉癌切除术后并发咽瘘的因素包括年龄、放疗、同期颈廓清、临床分期、手术方式、手术时间、术前血红蛋白质水平相关;护理后较护理前患者并发咽瘘发生概率、SAS与SDS评分均更低,生活质量评分呈更高显示;上述指标对比均有统计学意义(P<0.05).
