The tumors ranged from 5.5 to 20 cm and had a characteristic histologic appearance with irregular, sharply circumscribed nests and islands of bland-appearing spindled to focally epithelioid cells, surrounded by a cellular desmoplastic stroma.

这9例肿瘤大小为5.5至20cm，瘤组织特征性地表现为：温和的梭形细胞至灶性上皮样细胞排列成巢或成岛，这些细胞巢团界限相当清楚但不规则，周围间质细胞丰富、促纤维组织增生性。

METHODS: Bone marrow was sterilely separated from human. After heparinization, human BMSCs were harvested using density gradient centrifugation and adherence method. At the fifth passage, BMSCs at 1×108/L were incubated in the 6-well plate and divided into 2 groups. BMSCs in the edaravone group were 50% confluent and incubated in L-DMEM containing basic fibroblast growth factor and fetal bovine serum for 24 hours. After washing in PBS, these BMSCs were incubated in serum-free L-DMEM containing 20 mg/L edaravone for 24 hours. BMSCs in the blank control group were incubated in L-DMEM, supplemented with 10% fetal bovine serum.

无菌抽取的骨髓经肝素化后，采用密度梯度离心法及贴壁筛选法分离获得人骨髓间充质干细胞，传至第5代按1× 108 L-1接种于6孔板内，设立2组，依达拉奉组细胞达50%融合时用含碱性成纤维生长因子、胎牛血清的L-DMEM预诱导24 h，PBS洗涤后再用20 mg/L依达拉奉无血清L-DMEM诱导24 h；空白对照组始终用含体积分数为10%胎牛血清的L-DMEM培养，不加任何预诱导剂和诱导剂。

Methods: A rat chronic gastric ulcer model was made by infecting Hp(NCTC11637 strain)after injecting acetic acid into the subserosa of the stomach. In the experiments, the techniques of immunohistochemical stain and in situ hybridization etc. were used to observe the expression of bFGFmRNA and PCNA in th ulcer.
