基于重组酶聚合酶扩增（RPA）技术的樱桃病毒A（CVA）的检测方法
樱桃 樱桃病毒A 重组酶聚合酶扩增 检测
2020/3/3
根据樱桃病毒 A（cherry virus A，CVA）外壳蛋白基因序列的保守区设计特异性引物和探针，建立了樱桃中 CVA 的重组酶聚合酶扩增（recombinase polymerase amplification，RPA）检测方法。该方法可在恒温 38 ℃条件下进行，40 min 即可完成检测。灵敏度试验表明，采用 RPA 方法检测 CVA 的灵敏性是 PCR 方法的 10 倍，且与侵染樱桃的...

复方丹参对急性脑梗死CVA影响及其细胞保护作用研究
复方丹参 急性脑梗死 细胞保护
2008/11/11
本课题采用LH－450型CVA检测仪对128例急性脑梗死患者，行超早期脑循环动力学各项指标的检测，并与同期进行的头颅CT结果对比分析。研究证实脑循环动力学检测对缺血性脑卒中超早期诊断具有较高的敏感性，阳性率达95.16%。采用放免法和流式细胞仪测定急性脑梗死患者ET、CGRP和CD62p、GPⅡb-Ⅲa含量，观察复方丹参治疗前后上述指标变化，结果显示复方丹参治疗后，ET明显降低、CGRP明显...
