Objective:To explore C-terminal tensin-like(CTEN) gene in breast cancer tissue and its significance. Methods:Explore the prevalence and clinical significance of CTEN expression in invasive breast cancer cases ( n = 1409 ) using immunohistochemistry and tissue microarray. Results: The staining pattern for CTEN in breast tumour cells was homogenous cytoplasmic staining. Moderate to strong cytoplasmic immunoreactivity for CTEN was observed in 90% of the studied cases(1268 cases) . CTEN expression was significantly associated with poor prognostic variables including larger tumour size(χ2=4. 254,P=0. 044), higher histological grade(χ2=7. 555,P=0. 019),axillary nodal involvement(χ2=5. 842,P=0. 035),poor Nottingham Prognostic Index (χ2=7. 578,P=0. 016),Local recurrence(χ2=5. 211,P=0. 039),Regional recurrence(χ2=4. 778,P=0. 042),Distant metastases (χ2=4. 780,P=0. 041) and Histological type(χ2=7. 634,P=0. 012). Significant associations were observed between increased CTEN expression and up-regulation of phosphorylated-Akt(P-Akt)(χ2=27. 23,P<0. 001),Phosphoinositide 3 kinase(PIK3)(χ2=37. 22,P<0. 001) and N-cadherin proteins(χ2=26. 91,P<0. 001). Kaplan-Meier survival analysis demonstrated that patients with high CTEN ex-pression had significantly shorter Breast Cancer Specific Survival(P=0. 004) and Metastasis-Free Survival(P=0. 041) than those with low-CTEN expression. Multivariate analysis showed that CTEN was not an independent prognostic marker in breast cancer. Conclusion:CTEN expression increase is a cancer gene,its association with poor prognostic parameters,and the expression of CTEN associated with poor prognosis of breast cancer parameters.

Objective To study the effects of deep hypothermia and L-arginine(NO precursor) pretreatment on cerebral protection after circulatory arrest and resuscitation in a canine model. Methods Ten healthy adult dogs of both sexes, weighing 14.45?2.3kg, were randomly divided into two groups(n=5): sham treatment group and L-arginine pretreatment group. Extracorporeal circulation was established routinely,circulatory arrest was induced when the nasopharyngeal temperature was reduced to 18℃, then the animals were resuscitated 90min later with extracorporeal circulation. SjvO2 was measured at 30min before circulatory arrest, 0min, 45min, 90min after circulatory arrest and at 60minutes after resuscitation. The ultrastructure changes in cerabral cortex were observed with transmission electron microscope (HITACHI 7500). The brain water content was also determined after the dogs were sacrificed. Results SjvO2 had decreased obviously after circulatory arrest, attaining the lowest level in CA 90min.After resuscitation it increased again in both groups. The levels of SjvO2 in dogs of L-arginine pretreatment group were markedly higher than that of control group at 45min and 90min after circulatory arrest (P
