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。

Plant cellulose A extract, through the metabolic stimulation on the epidermis and dermis of eye lines, makes keratinized cell differentiation, promotes epidermal renewal, and promote the repairing of eye wrinkles by stimulating the synthesis of collagen and weakening the activity of metalloprotease that destructs elastic fiber.

植物纤维素A提取物，通过对眼纹的表皮和真皮层的代谢性刺激作用，对角质细胞分化，促进表皮更新，通过刺激胶原蛋白的合成和削弱造成弹性纤维毁坏的金属蛋白酶的活性，促进眼部皱纹的修复。

The PEA gene product was detected in the medium with Western blot, which indicated that the PEA gene with original signal peptide could be expressed with secretary form in eucaryotic cells.

表达产物经蛋白免疫印迹法（Western-blot）检测，表明本文构建的含有原基因信号肽的PEA基因能够在真核细胞进行分泌性表达，这为基于PEA的免疫毒素、疫苗佐剂和疫苗载体的研究奠定了基础。

Aim To study the effect and mechanism of action of total glucosides of paeony on synoviocytes from rats with collagen-induced arthritis.

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］。
