简介:摘要目的探讨门诊和住院患者中120例心电图高耸T波的临床特点及意义。方法;(1)肢体导联大于0.5mv,胸前导联大于1.0mV,但有些正常人可高达1.5mv。因此,高耸T波的动态改变更有意义。(2)T波大于同导联QRS波电压。结果急性心肌缺血60例(50%)、高钾血症10例(8.3%)、主动脉关闭不全2例(1.6%)、早期复极综合征12例(10%)、、完全性左束支传导阻滞10例(8.3%)、脑血管意外5例(4%),左心室肥大10例(8.3%),迷走神经张力增高5例(4%),正常变异6例(5%)。结论高耸T波是临床常见的心电图现象,可出现于多种情况,尤其对急性冠状动脉供血不足心肌梗塞早期、心肌缺血、高钾血症及脑血管意外具有重要的临床意义。

简介:摘要目的探究手术切除T4期肺癌的临床疗效。方法选择我院2011年5月至2015年12月收治的40例手术切除T4期肺癌患者为研究对象,总结这40例患者的资料,并且统计对患者生存率造成影响的因素,主要是治疗因素、病理因素以及临床因素等,对其进行统计、整理、分析以及比较。结果这40例手术切除T4期肺癌患者,年龄小于63岁的患者在手术之后三年或者是五年里存活率明显高于大于63岁的患者的存活率,手术中全部切除的患者在手术之后三年或者是五年里存活率明显高于手术中部分切除患者的存活率,根治切除的患者在手术之后三年或者是五年里存活率明显高于手术中没有根治切除患者的存活率,有淋巴结转移现象的患者在手术之后三年或者是五年里存活率明显高于手术中没有淋巴结转移现象患者的存活率。结论手术切除T4期肺癌患者预后直接和根治切除与否、淋巴结手否转移、手术切除的范围以及患者的年龄有关系。

简介:摘要目的比较非小细胞肺癌(non-smallcelllungcancer,NSCLC)患者外周血CD3+T细胞、CD4+CD25high调节性T细胞(regulatoryTcell,Tregcell)健康人的差异,并分析其临床意义。方法选取NSCLC患者和健康对照组各20例。分别抽取患者和志愿者的外周血3ml,分离其外周血单个核细胞(peripheralbloodmononuclearcell,PBMC),采用流式细胞仪检测CD3+T细胞比例、CD4+CD25highTreg细胞比例(%)。结果健康组CD3+T细胞比例为61.52±13.46%,肺癌组CD3+T细胞比例为55.15±20.11%,两组比较无显著性差异。健康组CD4+CD25highTreg细胞的比例为2.14±0.85%;肺癌组CD4+CD25highTreg细胞的比例为2.76±0.53%,较健康人明显升高(p<0.05)。结论非小细胞肺癌患者存在免疫受损,可能对此开发有效的免疫治疗方法。
