The role of beta irradiation on neointimal formation and apoptosis in vein grafts model / 中华外科杂志

<p><b>OBJECTIVE</b>To evaluate the effect of beta irradiation on intimal proliferation and apoptosis in vein grafts.</p><p><b>METHODS</b>Autogenous vein graft model was established in 80 rats by transplanting the internal branch of the jugular vein to the carotid artery by end to end anastomosis. The veins were irradiated by (32)P solution before anastomosis. Two dose schedules were studied: control group (graft, nonirradiated) and radiation group (20 Gy). The grafted veins were harvested at 3, 1, 2 and 4 week respectively after the operation. intimal hyperplasia (IH), smooth muscle cell (SMC), proliferation, p53, bcl-2 and bax were observed pathologically and immunohistochemically. They were analyzed by a computerized system. The presence of apoptotic VSMC was demonstrated by TUNEL method.</p><p><b>RESULT</b>There was a significant decrease in the average intimal thickness at 7, 14 and 28 days (t = 15.694, P < 0.05) in the radiation group. Immunohistochemical analysis of PCNA indicated decreased positive cells in the radiation group compared with the controls at 1 and 2 weeks (t = 60.157, P < 0.01). Apoptosis of VSMC was higher in the radiation group than in the control group at 2 weeks (t = 56.176, P < 0.01). There was no significant difference in expression of P(53) between the two groups, and there was a significant increase in bax/bcl-2 in the radiation group at 2 weeks (t = 9.783, P < 0.05).</p><p><b>CONCLUSION</b>These preliminary results demonstrated that low dose of beta irradiation in the vein graft inhibits SMC proliferation and induces the apoptosis of VSMC in rats.</p>

Expression of E-cadherin and ?-catenin in breast carcinoma and its′ significance / 中国普通外科杂志

Objective To detect the expression of E-cadherin and ?-catenin in breast carcinoma and analyze the relationship between E-cadherin and ?-catenin and the clinicopathological features. Methods The expression of E-cadherin and ?-catenin in breast cancer, paracarcinoma breast tissue, simple mastoplasia and atypical mastoplasia were detected by immunohistochemical method and the results were compared. Results The abnormal expression rates of E-cadherin and ?-catenin in breast cancer tissue were 51.9% and 61.1 %,respectively. Abnormal expression of E-cadherin was significantly correlated with histological grade. Abnormal expression of ?-catenin was significantly correlated with TNM staging, axillary lymph nodes metastasis and postoperative distant metastasis. COX multiple factor analysis showed that neither E-cadherin nor ?-catenin expression was an independent indicator for the prognosis of breast cancer. Conclusions Abnormal expressions of E-cadherin and ?-catenin are correlated with occurrence and development of breast carcinoma. Abnormal expressions of E-cadherin and ?-catenin are good indicators to judge invasion and metastasis of breast carcinoma.
