目的 探讨消化道吻合器在中、低位直肠癌保肛手术中的应用。方法 回顾分析120例直肠癌患者应用吻合器行保肛手术的临床资料。结果 本组保肛手术成功率为98.3%（118/120），吻合口漏发生率为3.3%（4/120），吻合口狭窄发生率为4.2%（5/120）。结论 在中、低位直肠癌行直肠前切除低位或超低位吻合术中使用吻合器，具有吻合成功率高，并发症少，操作安全简便的优点。
Penicillin is a kind ofβ-lactam drug which has been applied in the clinical treatment firstly in the world, and it has still been widely used at present. The synthesis and regulation mechanism of Penicillium chrysogenum, which is used to produce penicillin, has been studied quite maturely, but its proteomics research started relatively late and fewer reports were published. This paper reviews the synthesis and application of penicillin, transformation of Penicillium chrysogenum, and the research progress of its proteomics. On this basis, the study highlights the advantages of proteomics in the research of protein expression.
目的 报告螺纹管在左半结肠梗阻造瘘术中的应用以及术后护理的体会。方法 对近年来收治的36例左半结肠癌性梗阻患者行急诊梗阻近端结肠螺纹管造瘘，并与同期施行的20例结肠造瘘一期外翻成形做比较。结果 结肠螺纹管单腔造瘘术操作简单，术后患者获得满意的减压效果，未发生切口感染。而一期外翻成形者有3例发生切口感染。结论 左半结肠梗阻术中行螺纹管造瘘是一种简单、经济、省时、低污染、减压效果好、护理方便的手术方法。
Objective To evaluate the effect of ultrasound guided percutaneous drainage on acute perforation of gastroduodenal ulcer in elderly patients. Methods The clinical features, treatments, and the curative effects of 86 elderly cases (≥65 years) of acute perforation of gastroduodenal ulcer in our hospital between January 2004 and October 2009 were retrospectively analyzed. Twenty-one cases were treated by ultrasound guided percutaneous drainage (drainage group), and 65 cases were treated by exploring operation (operation group). Results Drainage group was cured and had no complications. In 15 patients which accepted recheck one month after drainage, gastroscope showed the ulcer healed in 12 cases， and improved in 3 cases. In operation group, 63 cases were cured and 2 cases died. Compared with the drainage group, there was no significant difference in cure rate (Pgt;0.05). However, 11 patients had operative complications in operation group, which was significantly more than that in the drainage group （Plt;0.05）. In 45 patients which accepted recheck one month after operation, gastroscope showed the ulcer healed in 38 cases， and improved in 7 cases. Conclusion For elderly patients with acute perforation of gastroduodenal ulcer， if the patients do not fit for exploring operation， ultrasound guided percutaneous drainage is proved to be a simple, safe, and effective means.
ObjectiveTo evaluate the curative effect of laparoscopic assisted and open D2 radical resection in treatment of advanced gastric cancer. MethodsThe clinical data of 76 cases performed by laparoscopic assisted D2 radical resection (laparoscopic group) and 104 cases performed by open operation (open group) from October 2010 to October 2012 in our center were retrospective analized.Operation related index, postoperative recovery, and extent of radical resection of tumor of 2 groups were compared. ResultsThe operative time of the laparoscopic group[(192.5±14.8) min]was longer than that open group[(171.5±16.5) min, P < 0.05].But the blood loss, postoperative drainage, length of incision, and hospital stay of the laparoscopic group were significantly less or shorter than those of open group (P < 0.05).There were no significant difference in postoperative complications and extent of radical resection of tumor between the 2 groups (P > 0.05).There were no residual tumor in distal margin and operatiive death case in both 2 groups. ConclusionComparing with open operation, the laparoscopic assisted surgery for advanced gastric cancer could achieve the same clinical outcomes, and obvious advantage of minimal invasion.
Objective To detect the anti-colon cancer ability of whole cell lysates pulsed dendritic cell (DC) which acts as an adjuvant. Methods Whole cell lysates of LoVo cells were extracted with freeze thawing method, then the monocyte-derived DC were pulsed with this cellular antigen. Subsequently, the capability of antigen pulsed DC to promote T lymphocytes proliferation and the ability of T lymphocytes to kill LoVo cells were detected by 3H-TdR incorporation and lactate dehydrogenase release methods, respectively. Results The whole cell lysates of LoVo cells pulsed DC significantly stimulated T cells proliferation, and the cytotoxicity abilities of primed T cells to kill LoVo cells were also enhanced. Conclusion Tumor cell lysates which act as the cellular antigen to pulse DC can improve the efficacy of anti-cancer immune response， which provides us an experimental evidence for cancer immunotherapy.
