Objective To assess the effectiveness and safety of hyperthermia combined with chemotherapy for advanced colorectal cancer. Methods Databases such as CNKI, VIP, WanFang Data, CBM, EMbase, PubMed and The Cochrane Library (Issue 3, 2012) were electronically searched from the date of their establishment to June, 2012, and the relevant literature and conference proceedings were also manually searched to include randomized controlled trials (RCTs) on comparison of chemotherapy with hyperthermia plus chemotherapy for advanced colorectal cancer. Two reviewers independently screened studies according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of the included studies. Then the meta-analysis was performed by using RevMan 5.1 software. Results A total of 11 RCTs involving 708 patients with advanced colorectal cancer were included. The results of meta-analysis showed that: a) as for effectiveness, the chemotherapy combined with hyperthermia group was superior to the chemotherapy group in the partial improve rate (OR=1.65, 95%CI 1.39 to 1.97, Plt;0.000 01) and the total effective rate (OR=3.59, 95%CI 2.51 to 5.12, Plt;0.000 01), with significant differences; b) as for safety, the chemotherapy combined with hyperthermia group was lower than the chemotherapy group in the incidence of neurotoxicity (OR=0.50, 95%CI 0.33 to 0.75, P=0.000 8). Conclusion Compared with chemotherapy, chemotherapy combined with hyperthermia can increase partial improve rate and total effective rate and reduce the incidence of neurotoxicity. Due to the limitation of the included studies, large sample size, multicenter, high quality studies are needed to verify the above conclusion. We recommend that chemotherapy combined with hyperthermia therapy could be applied to clinic combining individual conditions of patients.

摘要:目的：回顾性分析比较左半结肠癌急性梗阻一期手术与同期左半结肠癌根治术患者的手术临床资料,探讨左半结肠癌急性梗阻一期手术的可行性。方法： 回顾性将我中心2004年1月至2007年3月收治的59例左半结肠癌急性梗阻一期手术病例分为A组,将同期226例左半结肠癌根治术病例分为B组,比较两组之间清除淋巴结数、术后进食时间、吻合口漏发生率、肺部感染率、切口感染率、住院时间、复发和转移率。结果： 在上述观察指标中,在A组分别为（133±18）枚,（36±09）d,1/59（169%）,4/59（678%）,2/59（339%）,(124±09)d,6/59（1017%）；B组分别为128±15,32±08,1/226（044%）,8/226（354%）,6/226（265%）,117±15,23/226（1062%）；经统计学处理,两组间没有显著性差异。结论：术中合理应用结肠灌洗,良好的手术技巧,术后积极辅助治疗,左半结肠癌急性梗阻一期手术是安全可行的,可避免二次手术带给患者的痛苦,术后并发症也无明显增加。Abstract: Objective: Retrospective analysis and comparison of acute obstruction of left colon cancer onestage surgery and the same period a radical mastectomy in patients with left colon cancer surgery clinical data,To study the possibility of acute obstruction of left colon cancer onestage surgery. Methods:A retrospective of my center from January 2004 to March 2007 were treated 59 cases of acute obstruction of left colon cancer onestage surgery patients were divided into A group, will be left over the same period 226 cases of radical resection of colon cancer patients were divided into group B, compare the number of lymph nodes removed between the two groups, after the consumption of time, the incidence of anastomotic leakage, pulmonary infection, incision infection, length of stay, recurrence and metastasis rate. Results: Observed in the above indicators, in the A group were 133±18,36±09,1/59 (169%),4/59 (678%), 2/59 (339%),124±09,6/59 (1017%); B group were 128±15,32±08,1/226 (044%), 8/226 (354%), 6/226 (265%), 117±15,23/226 (1062%); Statistical analysis between the two groups there was no significant difference. Conclusion: Rational application of intraoperative colonic irrigation, good surgical technique, postoperative adjuvant treatment of active, acute obstruction of left colon cancer onestage surgery is a safe and feasible, it may avoid the second operation to bring the patient’s pain, postoperative complications and no increased significantly.
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.

Objective To evaluate the potential roles of celecoxib on proliferation and cell cycle progression of colon adenocarcinoma cells and on the hepatic metastasis of nude mice. Methods The human colon cancer cells HT-29 and HCT-116 were employed in the study. After treatment with celecoxib, the inhibitory effects of celecoxib on the proliferation of cancer cells were quantified by MTT assay, and the cell cycle progression was detected by flow cytometry, tumor cells were inoculated in nude mice, and the hepatic metastasis was detected. Results ①Celecoxib inhibited the proliferation of the tumor cells in time and dose-dependent manners （P＜0.05，P＜0.01）. The inhibitory effect on HT-29 cells was ber than that on HCT-116 cells （P＜0.05）. ②Celecoxib changed cell cycle progression of both kinds of cells, and decreased the proliferation index of both kinds of cells too. ③Celecoxib could inhibit the growth of the hepatic metastatic tumor obviously. Conclusion Celecoxib may inhibit the activity of cyclooxygenase-2, and resulting in the inhibition of division and proliferation, apoptosis of tumor cells and interfering in metastasis and relapse of colon cancer.
