Results The diagnostic accuracy of both MRI and X-ray film was 100%. Compared with X-ray, MRI was capable of clear display of the lesion extent, perpendicular periosteal reaction, the two layers of Codman's triangle and the skip lesions.

结果 MRI及X线平片对下肢骨肉瘤的诊断准确率均为100%，MRI在显示病变范围、放射状骨针、Codman三角两层结构以及跳跃病灶等方面明显优于X线平片检查。

To improve detection efficiency and result accuracy, we developed an improved multiplex PCR technique for specific detection of GMO.①The assay strategy involves multiplex PCR amplification of the target with several biotinylated primer pairs in one tube, followed by the hybridization of multiplex PCR products and membrane-bound oligonucleotide probes. The multiplex PCR/probe hybrid is detected colorimetrically using an alkaline phosphatase conjugate and a chromogenic substrate.

在多基因定性检测技术方面，本文在优化并确定了多基因PCR反应条件的基础上，采用了两种方法对多基因PCR产物进行鉴定：①采用共价结合方法将多个探针固定在Biodyne〓C膜上，将5'端标记生物素的多基因PCR产物与膜上的探针进行杂交及显色反应，首次建立了GMO的多基因PCR-膜相杂交检测方法，实现了一个反应体系中同时检测多种转基因成分的目标，提高了检测效率与准确率。
