目的总结进展期胃癌根治术的治疗经验，以提高手术治愈率。方法回顾性分析1995~2001年我院收治行手术治疗并获得远期随访的110例进展期胃癌患者的临床资料。 结果Ⅰ期12例，Ⅱ期29例，Ⅲ期69例。施行D1手术16例，5年生存率为31.25%; 行D2手术61例，5年生存率为44.26%; 行D3手术27例，5年生存率为44.44%; 行姑息性手术6例，5年生存率为零。其预后与肿瘤的大体类型、组织学类型、生长方式、癌浸润胃壁深度、胃癌部位、有无淋巴转移以及TNM分期密切相关。结论针对胃癌的生物学特性有选择性地施行胃癌D2或D3手术，扩大淋巴结清扫，并在围手术期采用综合治疗，对提高进展期胃癌的生存率十分必要。
目的为提高胆总管囊肿切除、胆肠RouxY吻合术的疗效，对其影响疗效的相关因素进行经验总结。方法对我院收治的34例小儿先天性胆总管囊肿进行回顾性分析。结果31例施行了手术，术后随访通过B超、X线胃肠钡餐检查表明30例治愈，疗效满意，1例新生儿术后并发吻合口漏死亡。手术治愈率96.8%，手术死亡率3.2%。结论为提高本术式的疗效，术前的B超、CT扫描以及术中的胆道造影，ERCP检查对判定本病类型，有无胰胆管合流异常，对选择手术方法和疗效有帮助，此外注意囊肿的病理改变及手术技术对提高疗效，减少并发症的发生也是十分重要的。
目的 探讨直肠癌的外科治疗及其并发症的防治。方法 回顾性分析了我院1995～2000年收治的360例直肠癌患者外科手术治疗情况，其中施行Miles手术196例，双吻合器吻合96例，手术缝合30例，姑息性手术38例。发生并发症19例。结果 341例治愈出院，18例并发症患者经手术或相应处理治愈，1例因多器官功能衰竭死亡。结论 直肠癌患者应根据肿瘤部位、恶性程度、Dukes分期而采用不同的术式，应注意从手术技巧的改进与提高上来防治其并发症的发生。
Objective To observe the effects of vascular endothelial growth factor antisense oligonucleotide (VEGF-ASODN) on expression of vascular endothelial growth factor (VEGF) and growth in gastric cancer cells. Methods The VEGF-ASODN was synthesized artificially with phosphorothioic acid. After transfecting with VEGF-ASODN in gastric cancer cells SGC-7901, the initial copy number of mRNA was detected by real-time RT-PCR, and the quantity of VEGF protein in both cell and supernatant were detected by ELISA. The levels of expression of survivin protein in cells were measured by Western blot. FCM and MTT method were used to detect cellular apoptosis and the activity of cells, respectively. The effect of transfection on the growth of cells was evaluated by growth curve. Results The copy number of VEGR mRNA, protein levels of VEGF in the cells and in culture fluid all decreased when the concentration of transfected VEGF-ASODN increased, as well as the levels of survivin protein （P＜0.05）. The ratio of apoptosis increased, the activity of cells also decreased as the concentration of transfected VEGF-ASODN increased （P＜0.05）. Conclusion Transfection with VEGF-ASODN in gastric cancer cells SGC-7901 can inhibit the expressions of VEGF and survivin remarkably. It can enhance cellular apoptosis and suppress growth of cells.
