  • EFFECT OF INTRAPERITONEAL HYPERTHERMO-CHEMOTHERAPY ON T-LYMPHOCYTE SUBSETS AND sIL2R LEVEL IN PATIENTS WITH GASTROINTESTINAL MALIGNANCY TUMOR

    To evaluate the effect of intraperitoneal hyperthermo-chemotherapy (IPHC) on immunologic function of patients with gastrointestinal malignant tumor (GMT). The authors determined the serum T-lymphocyte subsets (T-LS) and interleukin-2 receptor (sIL-2R) of 32 patients with GMT after IPHC, and compared the two indexes with 20 healthy control group. Results: Before IPHC the serum CD+3, CD+4, CD+8 and CD+4/CD+8 were higher and sIL-2R were lower than control group, after IPHC, CD+3, CD+4, CD+8 and CD+4/CD+8 increased obviously (P<0.01) and the serum sIL-2R decreased significantly (P<0.01). Conclusion: The IPHC can improve the patients immunologic function.

  • EFFECT OF RECOMBINANT HUMAN GROWTH HORMONE ON IMMUNOLOGIC FUNCTION IN PATIENTS WITH GASTROINTESTINAL MALIGNANT TUMOR

    To evaluate effect of recombinant human growth hormone (rhGH) on immunologic function in patients with gastrointestinal malignant tumor (GIMT). Before and 3 weeks after surgical treatment and administration of rhGH, the amount of T lymphocyte subset (T-LS) and soluble interleukin 2 receptor (sIL-2R) level were measured in 12 patients with GIMT, which were compared with 20 cases of normal control and 18 cases of GIMT treated by surgery alone. Result: ①In all GIMT patients, the serum CD+3, CD+4 level and the ratio of CD+4/CD+8 were lower than normal control and the sIL2R level was much higher; ②After operation, the serum CD+3, CD+4 level and the ratio of CD+4/CD+8 of all patients increased, the serum sIL2R level decreased; ③In patients recieved rhGH, the serum CD+3, CD+4 level and the ratio of CD+4/CD+8 were much more increased and the serum sIL-2R level much more decreased than those of surgery alone group. Conclusion: rhGH can enhance the immunologic function of patients with GIMT.

  • INTRAPERITONEAL PERFUSIVE THERMOCHEMOTHERAPY FOR PREVENTION OF POSTOPERATIVE RECURRANCE OF ADVANCED MALIGNANT TUMORS IN GASTROINTESTINAL TRACT

    Pre-and postoperative perfusion of thermochemotherapy was used in 25 cases of advanced malignant tumors of digestive tract.There were on significant changes in hepatic and renal functions after perfusions.The erythrocyte,leukocyte and platelet counts reduced in the second and third week after the beginningof perfusion,but rose up in the 4th week.A 2-year follow-up revealed that 23 patients were still alive without recurrence or metastases except 2cases died in the 6th and the 9th month after treatment.We claim that intraperitoneal thermochemotherapy is a simple and safe method. A prospective study is still necessaryin deciding the dose and course.

  • Relationship Between Histone Modifications and Gastrointestinal Cancer

    Objective To review the relationship between histone modifications and gastrointestinal cancer. Methods Literatures on histone modifications and the relationship between histone modifications and gastrointestinal cancer were collected and reviewed. Results Histone modifications played an important role in the establishment of gene silencing during tumorgenesis. DNA methylation and histone modifications might interact with each other and form a complex network to establish and maintain gene silencing. Restoring gene function silenced by epigenetic changes in cancer had the potential of ‘normalizing’ cancer cells, which was named epigenetic therapy. Epigenetic therapy was very promising in prevention and treatment of gastrointestinal cancer, but many unsolved issues remain which need to be addressed in future studies. Conclusion Histone modifications are associated with the pathogenesis of gastrointestinal cancer. Restoring gene function silenced by epigenetic changes may have a great role in the prevention and treatment of gastrointestinal cancer.

  • Short-Term Efficacy of Omega-3 Polyunsaturated Fatty Acid-Supplemented Parenteral Nutrition in Postoperative Gastrointestinal Malignancy: A Meta Analysis of Randomized Control Trials

    ObjectiveTo systematically evaluate short-term efficacy of omega-3(ω-3) polyunsaturated fatty acidsupplemented parenteral nutrition in postoperative gastrointestinal malignancy. MethodsThe literatures published randomized control trials (RCT) were searched in PubMed, Embase, Scopus, Cochrane Library, CNKI, Weipu, and Wanfang Databases. The immune efficacy outcomes ofω-3 polyunsaturated fatty acid-supplemented parenteral nutrition in patients with gastrointestinal malignancy were compared. All the relevant studies were screened and the data were extracted before January 2015. The quality of included literatures was assessed by the risk of bias table provided on Cochrane Library. Statistical analysis was performed by Revman 5.3 software. ResultsSixteen RCTs involving 1019 patients (511 in the study group, 508 in the control group) were enrolled into the analysis. The results of meta analysis:①In the cell immunity:The proportions of CD3, CD4, CD4/CD8 in the study group were significantly higher than those in the control group[CD3:WMD=6.09, 95% CI (2.40, 9.77), P=0.001; CD4:WMD=5.25, 95% CI (3.30, 7.20), P < 0.00001; CD4/CD8:WMD=0.40, 95% CI (0.22, 0.58), P < 0.0001].②In the humoral immunity:The levels of IgA and IgG in the study group were significantly higher than those in the control group[IgA:WMD=0.56, 95% CI (0.36, 0.77), P < 0.00001; IgG:WMD=2.88, 95% CI (0.63, 5.13), P=0.01].③The count of lymphocyte in the study group was significantly higher than that in the control group[WMD=0.27, 95% CI (0.10, 0.43), P=0.002].④In the cytokines:The levels of interleukin-6 and tumor necrosis factor (TNF)-αin the study group were significantly lower than those in the control group[interleukin-6:WMD=-16.75, 95% CI (-25.00, -8.50), P < 0.0001; TNF-α:WMD=-6.25, 95% CI (-10.55, -1.95), P=0.004].⑤The rate of postoperative infective complications in the study group was significantly lower than that in the control group[OR=0.36, 95% CI (0.20, 0.66), P=0.0008]. ConclusionFor postoperative patients with gastrointestinal malignancy, ω-3 polyunsaturated fatty acid-supplemented parenteral nutrition could improve immune function, decrease postoperative inflammatory reaction, and reduce rate of infective complications.

  • 术后早期应用低分子肝素对胃肠道恶性肿瘤术后深静脉血栓形成的影响

    目的探讨术后早期应用低分子肝素(LMWH)对预防胃肠道恶性肿瘤患者术后下肢深静脉血栓(DVT)形成的安全性和有效性。 方法将2014年7月至2015年7月期间徐州医学院附属医院普外科收治的92例胃肠道恶性肿瘤患者随机分为2组,即住院号末尾数为奇数者纳入低分子肝素组,偶数者纳入对照组,最终低分子肝素组47例、对照组45例。低分子肝素组于术后12~24 h开始于腹部皮下注射依诺肝素4 000 U,1次/d,用至术后第7天;对照组未采取预防性用药。术后第7天清晨抽取静脉血检测凝血功能、D-二聚体(DD)及血小板(PLT)指标;记录患者术后7 d内腹腔引流量,评价安全性;术后1周复查双下肢深静脉彩超,比较2组DVT发生率。 结果2组患者一般资料比较其差异无统计学意义,具有可比性(P>0.05)。术后第7天2组患者的凝血酶源时间(PT)、活化部分凝血酶时间(APTT)及PLT相比差异无统计学意义(P>0.05);低分子肝素组术后第7天纤维蛋白原(FIB)及DD明显低于对照组,差异有统计学意义(P<0.05)。2组患者术后7 d内腹腔引流量差异无统计学意义(P>0.05);2组患者术后下肢DVT发生率差异有统计学意义,对照组高于低分子肝素组(P<0.05)。结论术后早期应用低分子肝素可有效降低胃肠道恶性肿瘤患者术后下肢DVT形成,且不增加出血风险。

  • Advancements in investigating Gas6/Axl in gastrointestinal malignant tumors

    Objective To understand the research progress and future prospects of the growth arrest specific protein 6/Axl receptor tyrosine kinase (Gas6/Axl) signaling pathway in gastrointestinal malignant tumors. Method Retrieve relevant literature on the Gas6/Axl signaling pathway in gastrointestinal malignant tumors and analyze and summarize. Results The Gas6/Axl signaling pathway was abnormally upregulated and activated in gastrointestinal malignancies, leading to malignant cell proliferation, invasion, and metastasis, thereby promoting the occurrence and development of gastrointestinal malignancies. At present, in the field of gastrointestinal cancer, the research of Gas6/Axl signaling pathway mainly involved tumor angiogenesis, tumor drug resistance, mesenchymal epithelial transformation, and tumor microenvironment. Conclusions The Gas6/Axl signaling pathway plays a critical role in governing various cellular processes and downstream effects. Its aberrant expression contributes to the development and advancement of gastrointestinal malignancies through diverse mechanisms. Thoroughly exploring the involvement of the Gas6/Axl signaling pathway in gastrointestinal tumors is of utmost significance, as it holds the potential to unveil novel therapeutic targets for effective management of gastrointestinal malignancies.
