Results A middle age woman had a history of leiomyoma of uterus incision and CT scan shows several nodes in lung. Two gray-whitish nodes were found in the removal specimen, 6 cm、12 cm in respectively diameter, and well demarked from the around tissue. The neoplasia is plenty of tumor cells, some lumenoid structure lined with epithelium in the tumor tissue. Tumor cells is well differentiated and look like smooth muscle cells without the necrosis and karyo-kinesis. The pattern of tumor is similar to the original tumor.

结果 中年女性患者，有子宫平滑肌瘤手术史，胸部CT示右肺多发性结节切除标本见2个灰白色结节，直径分别为6 cm、12 cm，边界清楚，镜下见肿瘤细胞较丰富，并见上皮衬覆的管腔样结构，未见坏死及核分裂象，与原发子宫平滑肌瘤形态相似免疫组化证实为平滑肌源性，且表达雌激素受体。

Methods The changes of contents of AGEs in plasma and the abdominal aorta and changes of VSMC of the abdominal aorta were investigated with methods of fluorospectrophotometry, immunohistochemistry, computer image analysis and transmission electron microscopy on streptozotocin-induced diabetic rats. Results From the fourth week, in diabetic rats, the contents of AGEs in plasma and the abdominal aorta increased, the relative area of α-SM-actin in the abdominal aorta decreased, the density of nucleus of VSMC increased, and mitochondria and rough endoplasmic reticules in VSMC increased.

后者在早期主要是血管平滑肌细胞(vascular smooth muscle cell， VSMC)和胶原纤维增多，弹性纤维减少，动脉增厚等，引起动脉的顺应性降低，舒张功能减弱［1～3］；晚期主要表现为动脉粥样硬化和动脉硬化，其中以VSMC的增生和迁移较为突出，其表型也由收缩型转化为合成型［4，5］。
