目的 探讨术前控制营养状态评分在老年胃癌患者术后短期并发症中的应用价值。方法 回顾分析统计2015年1月—2020年12月在江苏大学附属医院接受治疗的确诊胃癌患者,根据纳入标准和排除标准,选择入组患者,收集纳入研究患者一般资料、术前实验室检测数据和术后并发症情况,计算控制营养状况（CONUT）评分,统计分析CONUT营养评分在老年胃癌患者接受胃癌D2根治术术后短期并发症的价值。结果 共223例患者纳入研究,CONUT评分的截断值为2.5,肿瘤直径的截断值为2.75 cm。CONUT评分>2.5组的平均年龄高于CONUT评分<2.5组（P=0.005 3）,且2组性别构成存在差异,男性患者多于女性（P=0.037 0）。CONUT评分>2.5组患者的肿瘤直径较大（P=0.039 4）。在术后并发症方面,CONUT评分>2.5组的术后并发症多于CONUT评分<2.5组（P=0.008 3）。单因素Logistic回归分析,年龄（OR=1.127;95%CI：1.028~1.236;P=0.011）、CONUT评分（OR=0.339;95%CI：0.151~0.764;P=0.009）是患者发生短期并发症的危险因素。多因素Logistic回归分析显示年龄（OR=1.115;95%CI：1.008~1.233;P=0.035）、CONUT评分（OR=0.414;95%CI：0.175~0.982;P=0.045）是患者发生短期并发症的危险因素。结论 CONUT评分作为老年胃癌患者术前营养评估项目可以有效预测患者术后短期并发症,进而提前进行营养干预,降低术后并发症发生率。

Objective To explore the value of controlling nutritional status score in short-term postoperative complications of elderly patients with gastric cancer．Methods The data of patients who confirmed gastric cancer and treated in the Affiliated Hospital of Jiangsu University from January 2015 to December 2020 were reviewed and analyzed．Patients were selected according to the inclusion criteria and exclusion criteria,the general data,preoperative laboratory test data and postoperative complications of the included patients were collected,and the controlling nutritional status（CONUT）score was calculated．The value of CONUT score in the short-term complications of elderly gastric cancer patients undergoing D2 radical gastrectomy for gastric cancer was evaluated．Results A total of 223 patients were included in this study．The cut-off value of CONUT score was 2.5 and the cut-off value of tumor diameter was 2.75 centimeter．The average age of the group with CONUT score > 2.5 was significantly higher than that of the group with CONUT score < 2.5（P=0.005 3）．Moreover,there was significant difference between the sex ratio of the two groups,with male more than female（P=0.037 0）．The tumor diameter was significantly larger in the group with CONUT score > 2.5（P=0.039 4）．In terms of postoperative complications,there was significantly more postoperative complications in the group with CONUT score > 2.5 than in the group with CONUT score < 2.5（P=0.008 3）．Univariate logistic regression analysis showed that age（OR=1.127;95% CI：1.028-1.236;P=0.011）and CONUT score（OR=0.339;95% CI：0.151-0.764;P=0.009）were the risk factors for short-term complications．Multivariate logistic regression analysis showed that age（OR=1.115;95% CI：1.008-1.233;P=0.035）and CONUT score（OR=0.414;95% CI：0.175-0.982;P=0.045）were the risk factors for short-term complications．Conclusions As a preoperative nutritional evaluation item for elderly patients with gastric cancer,CONUT score can effectively predict the short-term postoperative complications of patients,and then carry out nutritional intervention in advance to reduce the incidence of postoperative complications．

目的 探讨非小细胞肺癌（NSCLC）组织中转化生长因子β激活激酶1（TAK-1）与T细胞因子-4（TCF-4）在 mRNA以及蛋白水平的表达情况及其相关性,并分析两者与NSCLC患者临床病理因素的关系。方法 收集NSCLC手术标本51例,每例均包含肺癌组织及配对癌旁组织,所有患者的术后诊断均经病理结果证实,通过RT-PCR以及Western blot法检测TAK1、TCF-4在癌组织及配对癌旁组织中的表达情况,并通过SPSS进一步分析两者的相关性及其与临床病理因素的关系。结果 TAK1与TCF-4 mRNA以及蛋白水平在NSCLC患者癌组织中均高表达,其中TAK1蛋白的表达与NSCLC的TNM分期（P=0.022）、淋巴结转移（P=0.014）相关,TCF-4蛋白的表达与NSCLC的TNM分期相关（P=0.045）。TAK1在NSCLC组织中的表达与TCF-4呈正相关（r=0.427,P=0.002）。结论 TAK1 mRNA及蛋白水平在NSCLC组织中均高表达,并与TCF-4呈正相关,TAK1有可能成为NSCLC诊断及预后的一个潜在靶标,并且TAK1与TCF-4的联合应用有可能成为一种更为理想的NSCLC辅助诊断及临床治疗方法。

Objective To investigate the mRNA and protein expressions of transforming growth factor β-activated kinase 1（TAK1）and T cell factor-4（TCF-4）in non-small cell lung cancer（NSCLC）tissues and their correlation,and to analyze the relationship between TAK1/TCF-4 and clinicopathological factors in NSCLC patients．Methods Cancer tissues and matched adjacent tissues of 51 NSCLC patients in our hospital were collected．The postoperative diagnosis of all patients was confirmed by pathological results．The expression of TAK1 and TCF-4 in cancer tissues and paired adjacent tissues were detected by RT-PCR and Western blot,then SPSS was used to further analyze the correlation between TAK1 and TCF-4 and clinicopathological factors．Results TAK1 and TCF-4 mRNA and protein were highly expressed in NSCLC tissues,and TAK1 protein expression was significantly correlated with TNM stage of NSCLC（P=0.022）and lymph node metastasis（P=0.014）;TCF-4 protein expression was significantly correlated with TNM stage of NSCLC（P=0.045）．TAK1 expression in NSCLC tissues was positively correlated with TCF-4（r=0.427,P=0.002）．Conclusions TAK1 mRNA and protein were highly expressed in NSCLC tissues and positively correlated with TCF-4．TAK1 may become a potential target for the diagnosis and prognosis of NSCLC,and the combined application of TAK1 and TCF-4 may become a more ideal method for the auxiliary diagnosis and clinical treatment of NSCLC．

我国结直肠癌的发病率与死亡率逐年增加,约10%~30%新发结直肠癌患者可表现为急性肠梗阻,其中梗阻发生率较高的主要部位是左半结肠。急性梗阻性左半结肠癌患者的主要治疗方式仍是急诊手术（ES）,但术后并发症发生率及围手术期死亡率较高,自膨式金属支架（SEMS）被一些指南推荐为梗阻性结肠癌的初始治疗选择,SEMS可将部分ES转变为择期手术,支架置入后择期手术（SBTS）与ES相比不仅可改善患者的短期生存结局,且支架置入后新辅助化疗为梗阻性结肠癌的治疗提供了新的途径;就长期生存结果而言,选择SBTS还是ES存在一定的争议。对于支架置入后手术时机的选择尚未达成共识,有指南表明大约两周的短桥接间隔可使患者最大程度获益,因而可有效指导临床工作。肠道支架置入术目前看来是一种简单、有效的临时性或永久性的治疗手段。

In recent years, the incidence and mortality of colorectal cancer in our country have been increasing year by year．Around 10% to 30% of newly diagnosed colorectal cancer patients showed acute intestinal obstruction, which the left colon cancer has higher incidence．Emergency surgery（ES）is still the main treatment for patients with acute obstructive left colon cancer, but the incidence of postoperative complications and perioperative mortality are high．Self-expanding metallic stents（SEMS）can convert some emergency procedures into stent as bridge to surgery（SBTS）, which is recommended by some guidelines as the initial treatment option for obstructive colon cancer．SBTS can not only improve the short-term survival outcome of patients compared with ES, but also provide a new approach for the treatment of obstructive colon cancer with neoadjuvant chemotherapy after intestinal obstruction stent placement．The choice of SBTS versus ES is somewhat controversial in terms of long-term survival outcomes．There is no consensus on the timing of surgery after stenting, and current guidelines suggest that bridging intervals of approximately two weeks strike a balance between potential adverse events and long-term outcomes．At present, intestinal stenting is still a simple, feasible and effective temporary or palliative permanent treatment with few complications．

Objective To construct and characterize the size-variable nano-delivery system PAMAM/DOX-pep,examine its physicochemical properties and evaluate its antitumor and targeting effects in vitro. Methods Small particle size PAMAM/DOX was obtained by physically encapsulating DOX within the hydrophobic cavity of the cationic polymer PAMAM. The large size nano-delivery system(PAMAM/DOX-pep)was formed by tandem linking small size nanoparticles by MMP-2 sensitive peptide pep(CPLGVRGC)using SMCC as a cross-linker. The particle size,potential,physical and chemical properties,inhibitory effect,cell uptake and nuclear targeting effect of each nanoparticle on mouse breast cancer cells(4T1)were detected. Results The particle size of PAMAM/DOX was about 10 nm,and the drug loading rate was 23%. PAMAMAM/DOX-pep,formed after cross-linking of peptide,had a particle size of about 200 nm,which could release DOX slowly at low pH,and remained stable,safe and non-toxic in vitro for 7 days with low hemolysis rate,and its cellular uptake amount and nuclear targeting rate increased significantly after co-incubation with MMP. Conclusions Size-variable nanoparticles overcome size-induced delivery barriers to target and deliver drugs to the 4T1 nucleus,providing a new strategy for the design of nano delivery systems.
