The liver fibrotic model was induced by CCl4 i.p for 5wk. Telmisartan was given at the same time model establishment in each intervened group by administration lasted for 6wk. Decollate to get the blood of all rats after 7 weeks . ALT、AST and ALB of serum was detected by automatic biochemistry equipment. Hyaluronic acid was detected by ELISA detection. Liver and spleen was obtained to calculate the index. The liver pathological changes were observed in each group of rats after HE staining to evaluate the therapeutic effect of Telmisartan; TGF-β1、PPAR-γand PDGF of liver tissue was detected by the method of immunohistochemistry respectively; The mRNA expression of TGF-β1、MMP-1、TIMP-1、α-SMA、PPAR-γand iNOS was detected by RT-PCR detection, respectively.

Our findings demonstrate that in conjunction with clinical and radiographic findings, immunohistochemical evaluation with a panel of D2-40, EMA, brachyury, and GFAP is most useful in distinguishing chordoid meningioma from chordoid glioma, skeletal myxoid chondrosarcoma, extraskeletal myxoid chondrosarcoma, chordoma, low-grade chondrosarcoma, and enchondroma. A lack of strong, diffuse S100 reactivity may also be useful in excluding chordoid meningioma.

我们的结果表明，结合临床和影像学资料，D2-40、EMA、brachyury和GFAP这样一个免疫标记组合就能很好地鉴别脊索样脑膜瘤和脊索样胶质瘤、骨的黏液样软骨肉瘤、骨外的黏液样软骨肉瘤、脊索瘤、低级别软骨肉瘤、内生性软骨瘤。S100染色不强烈、不弥漫也有助于排除脊索样脑膜瘤的诊断。

OVCs were isolated by density ladder centrifugation in the 4th week, and then OVC's morphology was observed under transmission electromicroscrope and immunocytochemistry were performed to detect the expression of ICAM-1. Results Observing OVC's morphology under transmission electromicroscrope showed that OVC was infantile and undifferentiated with big nucleus, clear nucleolus, large nucleoplasm-ratio, small mitochondria, and little endoplast.

结果 透射电镜下观察到OVCs超微结构的改变为核大，核/浆比大，核仁小，胞浆内细胞器少，可见少量内质网和小线粒体，整个细胞呈幼稚、未分化状态；ICAM-1免疫细胞化学检测阳性；损伤肝组织HE染色和ICAM-1免疫组化检测显示，肝损伤初期，Hering管周围OVCs增生并且ICAM-1阳性表达，随着肝损伤的加重，OVCs继续增生，并且，OVCs沿增生的肝纤维向肝小叶迁移，同时，ICAM-1阳性表达也继续增多，并逐渐向肝小叶弥散分布；透射电镜下观察到，肝损伤初期，OVCs在Hering管周围增生，肝纤维随之增生，增生的OVCs与肝纤维黏附生长。

Results Observing OVC's morphology under transmission electromicroscrope showed that OVC was infantile and undifferentiated with big nucleus, clear nucleolus, large nucleoplasm-ratio, small mitochondria, and little endoplast. In initial stage of damaged liver, OVCs and the expression of ICAM-1 mostly distributed around Hering duct, and then gradually increased and expanded toward hepatic lobule, shown by staining paraffin sections with HE, immunochemistry and transmission electromicroscrope. Immunocytochemistry indicated that ICAM-1 expression on OVCs was positive.
