The notable proliferation was not observed by eyes in the local of injection. The infiltration of inflammation cells and mild proliferation of fibrocyte around dura mater was observed by HE stained in 4 and 8 weeks after injection. Infiltration and exudation of inflammation cells was observed by HE stained in epidural nerve root. Compared with group A, no changes of group B, C and D were observed under specific stained. Proliferation of type Ⅱ collagen fibers around dura mater was seen under immunohistochemical stained in 4 and 8 weeks after injection. There is no significant demyelination changes under LFB stained. The thickness and shape of the myelin sheath in epidural nerve root was not regular under transmission electronic microscopy in 4 and 8 weeks after injection. Fibroblast was also seen there. In nerve endometrium, macrophage could be seen under TEM, myelinated nerve fiber changed significantly, but nonmyelinated nerve fiber changed mildly. When 8 weeks, the changes of group D is smaller than the group B and C.

In this article, we used automotive immunohistochemical stainer to check the expressions of HBsAg and HCV antigens in 100 cases of HCC and their adjacent tissues, mean while, we checked their histological activity index and hepatic fibrosis degree. We also used radioimmunoassay to detect serum levels of 4 serum fibrosis markers and serum AFP levels in these cases. Immunofluorescence labeling and flow cytometry were used to check the T-cell subpopulations and the activity of NK cells of these 100 cases. Then the correlations among these factors were studied.

This pattern is characterized by the combination of pro-MMP-2 and membrane type 1 (MT1)-MMP expression, which drie pericellular generation of actie MMP-2 and local degradation of normal lier matrix. In addition there is a marked increase in expression of TIMP-1 leading to a more global inhibition of degradation of fibrillar lier collagens by interstitial collagenases (MMP-1/MMP-13). These pathways play a significant role in the progression of lier fibrosis.

Special staining methods, such as Masson and the Van Gieson staining were used to study the distribution of collogen fibers and elastic fibers. ResultsBy HE staining, the subepithelial connective tissues and vessels in the pterygium were more prominent than normal conjunctival tissues. An amorphous subepithelial superficial hyalinized zone and coarse eosinophilic granular materials were observed in the pterygia, but they were not found in normal conjunctival specimens. Coarse fibers were visible only in the deeper subepithelial connective tissues of pterygial samples. With Masson′s staining, the dense staining of collagen fibers was also more prominent in the pterygium than in the subepithelial connective tissues of normal conjunctiva. Abnormal collagen fibers were visible in the deeper sub-epithelial connective tissues of pterygial samples. With Van Gieson staining, abnormal collagen fibers were visible in the deeper subepithelial connective tissues. Dark coarse elastic fibers were found in the abnormal fibers only in the subepithelial deep connective tissues of pinguecula in the pterygia but not in the conjunctiva. With immunohistochemistry staining, MMP-3 was strong in the pterygial epithelium, moderate in fibroblast and absent from pterygial vascular walls. LN was strongly expressed in the blood vessel wall, moderately in the epithelial basement membrane and absent from the entire stroma.

A 46-year-old man presented with a gradually growing nodule on the left dorsal foot, which had been present for over 10 years. In the beginning, the lesion was treated as a keloid. Because of poor response to treatment, biopsy was arranged. Sections showed a dermal tumor composed of numerous foamy cells, hyalinized wiry collagen, spindle cells and entrapped collagen. The foamy cells were positive for KP1(CD68) and negative for S-100 protein and HMB-45. The histological and immunohistochemical results were consistent with the diagnosis of lipidized fibrous histiocytoma.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
