Chinese Journal of Tissue Engineering Research 2007;0(10):-
The performance and clinical application of the skull repair materials differ depending on their variety. Organic glass has ever been widely applied, but its biocompatibility is poor with the high infection rate of subcutaneous effusion; Bone cement is good at histocompatibility but bad at absorption, thus can be only used for parts of skull repair; Medical silica gel polyester grid is cheap and effective, however, local infection and material's expose occur, leading to unsatisfactory appearance; Titanium and Titanium-alloy, as one kind of high polymer materials, have achieved widely application on the clinical practice for repairing skull defects due to their good biocompatibility and physicochemical property, but many shortages are also observed. With the development of the society, patients require more and more, some insufficient materials for the repair have been abandoned, and the materials for repairing skull defects should be selected according to the individual condition. In this paper, various materials of the skull repair were compared concerning the property and clinical application, to search an optimal material for the skull repair, with the good biocompatibility and good clinical efficiency.

3.Research progress of a new therapeutic target in hepatocellular carcinoma glypican-3
Chinese Pharmacological Bulletin 2016;32(11):1486-1489
Glypican-3 ( GPC3 ) plays very important role in the regulation of cell growth and differentiation in hepatocellular car-cinoma ( HCC ) . GPC3 is closely related to the occurrence and development of HCC. A dramatic elevation of GPC3 expression has been reported in a large proportion of HCC, which suggests that GPC3 is remarkably sensitive and specific to the diagnosis of HCC. GPC3 is a potential therapeutic target of HCC. This paper reviews the structure and function of GPC3, the progress of im-munotherapy based on GPC3 of HCC, and discusses the prospect of therapeutic target of liver cancer in the future.

Aim To investigate the apoptosis of human gastric carcinoma AGS cells induced by cecropinXJ. Methods Human gastric carcinoma AGS cells and human normal epithelial cells GES-1 were co-cultured with different concentrations of cecropinXJ ranging from 0. 01 to 1 000 mg·L-1 for 24 h. MTT assay was used to observe the effects of cecropinXJ on the proliferation of AGS cells and GES-1 cells. The ultrastructural changes of the AGS cells were observed by transmission electron microscopy. Hoechst staining was used to de-tect cell apoptosis. The changes of intracellular reac-tive oxygen species ( ROS) and mitochondrial potential were analysed by flow cytometery. The expression of Bax, Bcl-2, caspase-3 and cytochrome C in mRNA level was investigated by qRT-PCR. Western blot was used to determine the protein expression of Bax, Bcl-2, caspase-3 and cytochrome C. Results CecropinXJ significantly suppressed the proliferation of AGS cells in vitro (P<0. 05) in a dose-dependent manner, IC50 =61. 19 mg·L-1 , but had no inhibitive effects on the proliferation of GES-1 cells. After treatment for 24 h, cecropinXJ induced AGS cells nuclear condensation, and increased ROS production, disrupted mitochondri-al integrity. The results of qRT-PCR and Western blot demonstrated cecropinXJ could up-regulate the expres-sion of Bax and down-regulate the expression of Bcl-2 , promote the release of cytochrome C and activate caspase-3. Meanwhile, cecropinXJ promoted caspase-3 activity in a dose-dependent manner, and cell death ratio of AGS cells induced by cecropinXJ was signifi-cantly reduced by caspase-3 and caspase-9 specific in-hibitors treatment. Conclusion CecropinXJ can in-duce apoptosis of AGS cells by downregulating Bcl-2 , upregulating Bax and activating caspase-3 , which may be one of its anti-tumor mechanisms.

The effects of sophoramine (SA) on immune system in normal mice were studied. SA 15. 20mg/kg reduced the weight of thymus,decreased the rate of E rosette,and also suppressed T lymphocyte transformation. The weight and the hemolytic plaque of spleen were not influenced by SA at 15. 20mg/kg. At the dose of 25mg/kg,SA reduced the weight of thymus and spleen,decreased the rate of E rosette and suppressed the T lymphocyte transformation. All of the doses of SA didn' t affect the phagocytotic function of peritoneal macrophage.

Objective We report the pathological features of lung in the dead patients with severe acute respiratory syndrome (SARS). Methods Post-mortem lung and pulomonary hilar lymph nodes tissues of 3 patients dead from SARS were studied by histology and immuhistochemistry with rabbit anti-Fas polyclonal antibody, mouse anti-PCNA, mouse anti- CD83,mouse anti-CD4 and mouse anti-CD8 monoclonal antibodies. Results The surface of lung from 3 cases were shown red or purplish red color. Histopathological examination showed that diffuse interstitial exudative or leakage inflammation and alveolar damages with a pronounced increase of of monocytes in the interval at various levels of progression and severity. There were hyaline-membrane formation, desquamation and apoptosis of type-2 pneumocytes in alveolar spaces. Fibrin thrombus and thrombo-embolism could be found in blood capillary and bronchial artery respectively. We observed some fibrin deposition in alveoli interval. No obviously giant-cell infiltrate within the alveolar lumen. The positive cell of proliferative cell nuclear antigen (PCNA) was rare. Fas antigen were expressed in a lot of type-2 pneumocytes, monocytes of the interval and pulomonary hilar lymph nodes. Comparison with the lymph nodes of chronic inflammation, there were obviously disorganization and attenuation of lymphocyte in lymph nodes of SARS. The proportion of CD4 positive lymphocytes were rare, but CD83 and CD8 positive lymphocyte seemed no decreased, relatively. The seminal changes such as decreased lymphocytes ,white pulp atrophy,hemorrhage and necrosis,and decreased expression of lymphocytes for CD4 antigen could also observe in spleen. Conclusions Severe damages of lung and immunological system damages might lead to death of patients with SARS.

Objective To observe pulmonary fibrosis in severe acute respiratory syndrome (SARS) and to discuss the mechanisms of pulmonary fibrosis in SARS. Methods Hematoxylin and Eosin staining (H&E), histology staining and immuno-histochemical staining (SP methods) were used to investigate the lungs from 4 autopsy cases. Antibodies against collagen type Ⅲ, ?-smooth muscle actin(?-SMA), Fas, FasL and transforming growth factor ?1(TGF-?1) were used for immunohistochemical studies. Results All these four lung tissues showed different degree of pulmonary fibrosis, including the organization of exudative fibrin, glomerulus-like fibrosis in alveolar spaces, the thickening of the alveolar septum, proliferation of fibroblasts, the hyperplasia of collagen fibers and the consolidation of lungs. Sirius red staining and collagen type Ⅲ staining showed the type Ⅲ and the type Ⅰ collagen fibers were the main components of the hyperplastic collagen fibers. ?-SMA were expressed in fibroblasts, immunoreactivity to Fas, FasL, TGF-?1 were all positive and located in plasma of pneumocytes, macrophages and lymphocytes. Conclusions The pulmonary fibrosis can be observed early in SARS patients and the pathogenesis may be involved in the co-effect of many effective cells, inflammatory mediators and cytokines.
