Methods There were 165 cases of mesenchymal tumors were investigated the expression of nestin by immunohistochemistry, including 96 CD117-positive GISTs, 5 CD117-negative GISTs, 10 oesophagus leiomyomas, 33 digestive tract Schwannomas, 6 fibromatosis and 15 leiomyosarcomas in abdominal cavity.

用免疫组化EnVi-sion法检测96例CD117阳性、5例CD117阴性的GISTs，以及食管平滑肌瘤（10例）、消化道雪旺瘤（33例）、肠纤维瘤病（6例）以及腹腔平滑肌肉瘤（15例），观察这些肿瘤中nestin的表达状况。

A static headspace GC-MS method was used to detect sulfur in the fumatory Radix Bupleuri,the authentic samples free of sulfur was detected as reference.

运用静态顶空毛细管气相色谱-质谱联用技术进行检测市售柴胡是否经硫黄熏蒸，并从产地采集未经硫黄熏蒸的柴胡作为阴性对照药材与市售柴胡进行比较。

Results (1) In the controls and the dilated intestine segment of the HD,CAD-positive ganglionic cells were observed in myenteric and submucosal plexus.

结果 （1）在正常对照组与HD扩张段组肠壁肌间和黏膜下层可见CAD只对神经丛中神经节细胞阳性表达，对神经纤维与神经胶质细胞均不表达。S-100染色与CAD染色相反，神经纤维与神经胶质细胞均阳性表达，神经节细胞阴性表达，表现为阳性神经丛中细胞状&空白区&。

Of 763 patients who tested negatie, 317 turned out to hae been gien wrong results.
