Objective To explore significance and impact of hypoxia inducible factor 1α,metastasis associated with colon cancer 1 and transcription factor FOXO4 in gastric carcinoma and clinical pathological characteristics and prognosis .Methods 110 samples diagnosed as gastric carcinoma and 46 samples diagnosed as pericarcinomatous tissue which was 5 cm far away from cancer were collected in first affiliated hospital of Anhui medical university from December 2006 to May 2008 .Immunohistochemical stai-ning was performed in these samples to detect the expressions of HIF-1α,MACC1 and FOXO4 .And the correlation between devel-opment of gastric carcinoma and expressions of HIF-1α,MACC1 and FOXO4 was analyzed with the help of patients′messages .Ka-plan-Meier method and Cox regression were used to analyze patients′5 years survival rate and the factors .Results The expression levels of HIF-1α(P<0 .001) and MACC1(P<0 .001) in gastric carcinoma tissues were significantly higher than pericarcinomatous tissues ,however the expression levels of FOXO4(P<0 .001) was significantly decreased in gastric carcinoma tissues .Statistical a-nalysis revealed that the expressions of HIF-1αand MACC1 were apparently increased with the lower degree of cell differentiation , the greater degree of tumor infiltration ,accompanied with lymph node metastasis and higher TNM scores ,but lowered the expres-sion of FOXO4 factor .There were significant correlations between expressions of the three factors in gastric carcinoma .The expres-sions of HIF-1α,MACC1 and FOXO4 had an apparent influence on the patients′5 years survival rate .And they were independent factors on the prognosis of gastric carcinoma .Conclusion HIF-1α,M ACC1and FOXO4 are abnormal expression in gastric cancer tissue ,and the clinical pathological features of gastric cancer and the prognosis of patients with gastric cancer are closely related .

Objective To evaluate the antitumor effect of corosolic acid and its impact on CAM and YSM angiogenesis.Methods The effects of CRA on A549 proliferation was studied by MTT method in vitro.Tumor-bruden nude mice model were established by injecting A549 lung cancer cell marked with bioluminescent to nude mice,and the growth of tumor in mice were detected by IVIS small animal in vivo imaging system.Experiment of chicken embryos eggs are used to observe the role of drugs on CAMand YSMblood vessels. Results The value of IC50 of CRA for A549 in vitro was 26.8μg/mL.A tumor-burdened animal experiment results showed that the CRA to A549 solid tumor has a certain therapeutic effect.CAM and YSM blood vessels of chicken embryos eggs treated with CRA were decreased significantly than negative control group.Conclusion CRA has certain therapeutic effect for A549,which may be related to the inhibition of angiogenesis in tumor tissues.

Objective To observe the granule tissue remodeling under neoepithelium in minitype pigs' full thickness dermal wounds and discuss the relation between the remodeling and possible ulcers or scars. Methods After the establishment of eight full-thickness dermal wound models with the diameter of 4 cm on the back of six minitype pigs, the specimens were collected from wound edge and wound center immediately, 3, 6, 9, 12, 15, 20, 25, 30 and 45 days, respectively after injury for HE staining, immunohistochemical staining and Van Gieson staining and then observed under light microscope to count the cell number, fibroblasts and vascular endothelial cells as well as evaluate the quantity and arrangement of collagens. Results The mean wound healing time was (29.3?1.8) days. After 9-25 days, the granule tissues in the wound center contained more cells, fibroblasts, collagen and vascular endothelial cells than those under neoepithelium of wound edge (P 0.01). Meanwhile, the collagen quantity and arrangement style of granule tissues under neoepithelium during wounds healing (12-30 days) assembled those under neoepithelium 15 days after wound healing. Conclusion Granule tissue remodeling exists during the healing of full thickness dermal wound.

AIM: To examine the expression of alpha-smooth muscle actin in scar tissue, and observe the phenomenon of apoptosis and its involvement in the process of pathological scarring and the presence of myofibroblasts or absence of cell in the dermis. To investigate the potential role of reparative cell apoptosis in hyperplastic scar formation. METHODS: The samples of scar were obtained from post-burn patients undergoing plastic operation in our burn unit recently, and the samples of control came from skin donor site of the same patient correspondingly. TUNEL assays were performed to evaluate the number of apoptotic cells in scar versus normal skin. In situ hybridization and immunohistochemistry staining technique were employed to determine the expression of different dermis cells markers in scar tissue and normal skin. RESULTS: There existed evident difference in apoptotic cells in the dermis between scars tissue and normal human skin. The expression positive cells were much more in hyperplastic scars than that in normal human skin; the apoptotic cells of proliferative stage were slight more than that of mature stage. However, in proliferative stage, the number of apoptotic cells was higher for the combination of hyperplastic scar than normally healed flat scars. But in mature stage, no obviously difference was detected between hyperplastic scar and normally healed flat scar. The monoclonal anti-? smooth muscle actin (ASMA) expression was significantly stronger in proliferative stage than that of mature stage. CONCLUSIONS: With reconstitution of dermal tissue, myofibroblasts containing alpha-SM actin disappear under normal wound healing, probably as a result of apoptosis. The myofibroblast play a critical role in wound closure and in the pathologic sequelae of healing.
