Objective To explore the expression of TRIB2 in colon cancer and its relationship with prognosis and immune cell infiltration. Methods TIMER database was used to analyse the expression of TRIB2 in pan-cancer．RNA-seq data and clinical information of colon cancer patients were downloaded from TCGA and GSE17538 to assess the correlation between TRIB2 with clinicopathological features．Survival curves,univariate and multivariate COX regression analysis were performed to explore the correlation between TRIB2 and prognosis,and a nomogram was constructed．Gene enrichment analyses were performed for TRIB2．Correlations between TRIB2 expression and immune cell infiltration,immune checkpoints,tumor mutation burden（TMB）,and immunotherapy sensitivity were analyzed．Results TRIB2 was highly expressed in colon cancer tissues（P<0.05）．The highest level of TRIB2 mRNA expression was found in CMS1．TRIB2 was an independent prognostic factor for colon cancer patients（univariate Cox regression analysis：HR=1.397,95%CI：1.100-1.774,P=0.006;multivariate Cox regression analysis：HR=1.502,95%CI：1.158-1.947,P=0.002）．TRIB2 was closely associated with immune cell infiltration and positively correlated with the expression level of immune checkpoint molecules as well as TMB（r=0.39,P<0.001）．The expression of TRIB2 was correlated with the efficacy of immune checkpoint inhibitors．Conclusions TRIB2 is highly expressed in colon cancer and is closely associated with poor prognosis and the immune microenvironment of colon cancer patients．

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．

目的 分析互联网+联合分段式心理干预对结肠癌患者生活质量及希望水平的影响。方法 采用随机数字表法对照试验,于2019年12月—2022年12月选取本院收治的100例结肠癌患者,分为参照组（50例,给予常规心理护理）与试验组（50例,给予互联网+联合分段式心理护理）,比较2组患者在护理前后的精神状态、生活质量、希望水平及护理满意度。结果 护理后,2组患者的简明精神病评定量表（BPRS）评分均降低,且试验组评分优于参照组（P<0.05）;2组患者的简明健康状况调查表（SF-36）各维度评分均升高,并且试验组评分更高（P<0.05）;2组患者的Herth希望量表（HHI）各维度评分均升高,且试验组评分高于参照组（P<0.05）;试验组患者（96.00%）护理满意度高于参照组（80.00%）（P<0.05）。结论 结肠癌患者采用互联网+联合分段式心理干预可改善患者精神状态,提高结肠癌患者生活质量、希望水平。

Objective To analyze the effect of internet combined with segmented psychological intervention on the quality of life and hope level of colon cancer patients. Methods In a randomized controlled trial,100 patients with colon cancer admitted to our hospital from December 2019 to December 2022 were selected as the subjects of this study. According to the nursing methods,they were divided into control group(50 cases,given conventional psychological nursing intervention)and experimental group(50 cases,given internet combined segmented psychological intervention). The mental status,quality of life,hope level and nursing satisfaction of the patients in the two groups were compared. Results After nursing,the score of Brief Psychiatric Rating Scale was decreased in both groups,and the score of experimental group was better(P<0. 05). The scores of all dimensions of the concise Health Survey Questionnaire increased in both groups,and the scores of the experimental group were higher(P<0. 05). The scores of Herth Hope index were increased in both groups,and the scores of experimental group were higher(P<0. 05). The nursing satisfaction of experimental group(96. 00%)was higher than that of control group(80. 00%,P<0. 05). Conclusions The use of internet combined segmental psychological intervention in colon cancer patients can improve the mental state,improve the quality of life and hope level,with promotion value.

Objective To study the expression of transcription factor KLF8 in colorectal cancer tissue and its effect of downregulation KLF8 on colorectal cancer cell. Methods Collecting cancer tissues and adjacent normal color tissue and detecting the protein level of KLF8. Culturing the colorectal cancer Lovo cell lines and detecting cell invasion, cell migration and epithelial-mesenchymal transition after transfecting of KLF8 siRNA. Results KLF8 was highly expressed in colorectal cancer tissues compared with adjacent normal colon tissue. After transfection of KLF8 siRNA, the migration distance of colorectal cancer cell and the cell population transferred to the lateral surface of transwell microporous membrane were lower than those of negative control siRNA. E-cadherin of KLF8 siRNA group were higher than those of negative control siRNA group. Vimentin and N-cadherin were lower than those of negative control siRNA group. Conclusion The expression of KLF8 in colorectal cancer tissue is elevated;downregulation of KLF8 expression in colorectal cancer cell lines may inhibit cell invasion, cell migration and epithelial-mesenchymal transition processes.

目的 探讨腹腔镜手术与传统开腹手术对右半结肠癌患者免疫功能指标及临床疗效的影响。方法 选取80例右半结肠癌患者,随机分成两组,各40例分别行腹腔镜手术及传统开腹手术,分别比较两组患者手术前后免疫功能指标及相关临床疗效的差异。结果 腹腔镜组及开腹组术后免疫指标CD3⁺、CD4⁺、CD8⁺均出现不同程度下降,但腹腔镜组免疫指标CD3⁺、CD4⁺均优于开腹组(P＜0.05);腹腔镜组术中出血量、术后胃肠排气功能恢复时间、住院时间均优于开腹组(P＜0.05);两组手术时间及淋巴结清扫个数方面无显著差异(P＞0.05)。结论 腹腔镜手术治疗右半结肠癌不仅对患者免疫功能损害较低,还较开腹术具有术中出血量少、术后恢复快等优点,值得临床推广。
