There are mainly two methods in the treatment of hepatic fibrosis. One is to aimdirectly at the causes by inhibiting hepatitis virus, killing blood fluke, alcoholwithdrawal, removing iron or coin, etc. The other is to suppress fibrosis itself byinhibiting the activation of HSC and proliferation of collogen, as well as promotingthe degradation of collogen.

抗纤维化的治疗一般包括两个方面：①是针对原发病的病因治疗，如抗肝炎病毒、抗血吸虫病、戒酒、去铁和去铜等；②是针对肝纤维化本身的治疗，如抑制HSC的激活、抑制胶原的增生、促进胶原的降解等。

Among them, in tumour of glue mother cell, visible head pledges fasciculus is interrupted in vain, its stop fiber to be able to be through corpus callosum; in meningeal tumour, visible tumour oppresses the head that cause pledges the fiber shift and remaining, fasciculus; that is departed is in in vain a tumour of cell of metamorphic star form is medium, DTT expression sends place head to pledge fasciculus is interrupted in vain formerly for tumor and tumor countershaft dash forward infiltration.

其中，在胶母细胞瘤中，可见脑白质纤维束中断，其终止纤维可通过胼胝体；在脑膜瘤中，可见肿瘤压迫引起的脑白质纤维移位以及残存、被分离的纤维束；在间变性星形细胞瘤中，DTT表现为肿瘤原发部位脑白质纤维束中断以及肿瘤对轴突的浸润。

Methods:(1) ADM was produced from swine skins treated with trypsin followed by Triton X-100.(2) type I collagen of mouse tail was extracted by 0.5mol/L acetoacetic acid.(3) Two kinds of ADM were got by being soaked with 0.02% glutaraldehyde for 5~10 min or being soaked with mouse type I collagen for 24h, then preserved at 4℃.

(1)应用胰蛋白酶消化-去污剂法制备ADM；(2)用0.5mol/L乙酸溶液提取制备I型鼠尾胶原；(3)用0.02%戊二醛溶液浸泡ADM5-10min，制成交联型ADM；另一部分ADM用质量分数0.25%的I型鼠尾胶原浸泡24h，制成胶原包埋型ADM，冰冻保存；(4)用酶消化法培养原代成纤维细胞，取第三代增殖期细胞，将其调整至浓度为2×105/ml的成纤维细胞悬液。

Results Among the 52 cases, 30 cases were confirmed to fibrosarcomas, which were identical with primary dingnoses;22 cases were revised to malignant fibrous histocytoma (8 cases), malignant nerve sheath tumor (4 cases), monophasic spindle cell synovial sarcoma (3 cases), leiomyosarcoma(3 cases), rhabdomyosarcoma(2 cases) and abdominal desmmoid tumor (2 cases). Of the 18 cases, only two cases were misdiagnosed and were revised to malignant fibrous histocytoma and spindle cell synovial sarcoma, respectively.

结果：1980年前52例中维持原诊断30例，修改诊断22例(42.3%)，分别为恶性纤维组织细胞瘤8例、恶性神经鞘膜瘤4例、单相性梭形细胞滑膜肉瘤3例、平滑肌肉瘤3例、横纹肌肉瘤2例、韧带状纤维瘤2例；1980年后纤维肉瘤18例中，维持原诊断16例，修改诊断2例(11.1%)，分别为恶性纤维组织细胞瘤和滑膜肉瘤各1例。

Results Histologically, the tumor was composed of mildly cellular benign-appearing spindle-shaped cells and bands of hyalinized collagen in varying proportions from area to area, and a typical patternless archite...

结果镜下见肿瘤组织由不同比例的纤维母细胞和胶原构成，纤维母细胞分化良好，形态多样，散乱穿梭于胶原蛋白束之间或环绕在玻璃样变的血管周围，伴有局灶性致密区域；胶原成分发生玻璃样变，局部呈轮辐状或瘢痕状排列。

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.

其降解肝正常基质，同时抑制引起肝纤维化的纤维胶原降解，这种情况的特点是前明胶酶A合成和膜型1－MMP表达，使得小叶内细胞激活MMP-2和降解当处的正常肝基质，此外血浆1型组织基质金属蛋白酶抑制剂（TIMP-1）明显升高引起广泛的抑制间隙胶原酶(MMP-1/MMP-13)对纤维肝脏胶原的降解。

To evaluate the role of collagen Ⅰ,Ⅲ and Ⅳ in the formation of the pericystic layer of hepatic hydatid cyst The expression of collagen Ⅰ,Ⅲ and Ⅳ in pericystic layers of hepatic hydatid cysts from 40 patients was observed using immunohistochemical methods.

Some cell dropped into the cavity and became free. Thrombosis or part organization could be seen. The internal elastic layer became thin, disappear or broken. In internal and middle layer existed fibroblasts, fibrocytes and collagen. Some of the wall indicated hyaline change, soomth muscle cell decreased greatly. The massive inflammatory cells invaded the middle and external layer. There were many foam cells in the capsule tissue. Cytoplasm was filled with fatty tissue and cholesterol. some cavities were full of thrombosis. Some thrombosis was fibrosis, the bottom was organization. The surface of the thrombosis existed red blood cell and librae.(2)Elatic fibrila staining: the internal elastic menbrane almost completely disappeared, the intact internal elastic menbran could be seen in the new small vessels.
