Objective: Thorough, prompt enteral decompression technique without contamination was de- veloped to ensure safety for emergent colon resection and primary anastomosis. Methods: After isolating the mesentery, the “to be resected colon segment” was cut at its lower end, then the proximal cut end was put into a plastic bag which was adhered to one side of the operating table. After releasing the clamp, the content could ?ow into this bag. The operator could squeeze the bowel with two hands by turns, from proximal to farness, and from small bowel to large bowel, until the entire bowel content was fully discharged. Then the upper end of this “to be resected colon segment” was cut, and was removed together with the plastic bag. Results: 31 cases of left colon cancer with acute obstruction were decompressed with this technique. They all recovered smoothly, without anastomosis ?stula. Another 6 cases of hepatic seg- mentectomy with incidental colonectomy were decompressed with this technique and had the same results. This technique was also used in di?erent kinds of acute small intestinal obstruction and gained satisfactory results. Conclusion: This technique could be considered as the preferable choice for intraoperative enteral decompression.
目的探讨过表达干扰素诱导跨膜蛋白3(IFITM3)对胆囊癌细胞MHCC97H增殖、迁移、侵袭的影响。方法构建IFITM3-pc DNA3.1过表达载体,并将IFITM3-pc DNA3.1及pc DNA3.1转入MHCC97H细胞中,同时设立正常对照组。采用实时荧光定量聚合酶链反应(PCR)法检测IFITM3、B细胞淋巴瘤/白血病-2相关X蛋白(BAX)、B细胞淋巴瘤/白血病-2(Bcl-2)表达,CCK-8法检测细胞活力,划痕实验检测细胞迁移能力,Transwell实验检测细胞侵袭能力。结果酶切结果证实IFITM3过表达载体构建成功。与正常对照组及过表达对照组比较,过表达组MHCC97H细胞IFITM3 m RNA表达量上调,光密度值(OD)升高,细胞迁移速率加快,细胞侵袭数目增加,Bcl-2 m RNA表达水平上调,BAX m RNA表达水平下调,差异均有统计学意义(P﹤0.01)。结论过表达IFITM3能显著促进MHCC97H胆囊癌细胞增殖、迁移及侵袭,与调控Bcl-2及BAX表达有关。
