目的 探讨显微手术治疗破裂大脑中动脉动脉瘤（MCAA）的适应证、术前评估及手术技巧。 方法 回顾性分析2008年1月－2011年1月经翼点入路行显微外科手术治疗的65例破裂MCAA患者的临床资料。其中男40例，女25例；年龄22～78岁，平均46.8岁。术前Hunt-Hess分级：Ⅰ级15例，Ⅱ级25例，Ⅲ级13例，Ⅳ级10例，Ⅴ级2例。动脉瘤直径＜5 mm 10个，5～15 mm 36个，15～25 mm 15个，＞25 mm 4个，平均7.8 mm。其中56例动脉瘤位于大脑中动脉分叉部，5例位于大脑中动脉的M1段，4例位于分叉后M2段。 结果 手术夹闭动脉瘤60例，余5例行动脉瘤夹闭加包裹术。患者术后获随访3～36个月，平均16个月，均无动脉瘤复发或再出血发生。按格拉斯哥预后评分（GOS）结果评定：恢复良好58例（GOS 4～5分），差5例（GOS 2～3分），死亡2例（GOS 1分）。 结论 充分的术前评估，合适的手术入路选择，以及手术技巧的灵活应用是显微外科手术成功治疗破裂MCAA的保证。
Objective To explore the effectiveness of the transforming growth factor-β1(TGF-β1) and tumor necrosis factor-α(TNF-α) inducing human bronchial epithelial(HBE) cells to optimize epithelia-mesenchymal transformation(EMT) model. Methods Blank control, TGF-β1 10 ng/ml, TNF-α 10 ng/ml, TGF-β1 10 ng/ml+TNF-α 10 ng/ml induced human epithelial cells for 24 hours. Then the change of morphological alteration were observed by applying CCK8, cells migration assay and Western blot technique. Results When TGF-β1 plus TNF-α induced human epithelial cells for 24 hours, most of HBE cells traits changed including morphological alteration from cobblestone to fusiform, connection between cells vanishing, intercellular space broadening. In the experiments of checking cell migration capacity by the vitro scratch test, the group spacing was 420.06±10.38 μm in the blank control group, 499.86±34.00 μm in the TGF-β1 10 ng/ml group, 514.93±10.56 μm in the TNF-α 10 ng/ml group, 569.68±33.58 μm in the TGF-β1 10 ng/ml+TNF-α10 ng/ml group. TGF-β1 cooperated with TNF-α led to scratch spacing narrowing significantly. Western blot analysis showed that expression of E-cadherin and Vimentin varied significantly in the TGF-β1+TNF-α group. Conclusion Inducing human bronchial epithelial cell by TGF-β1 cooperated with TNF-α optimizes EMT model.
