Objective To investigate the expression levels and prognostic value of transcription factor E-box binding to zinc finger protein 1（ZEB1）and lysosomal associated membrane protein 5（LAMP5）in colorectal cancer tissues. Methods A total of 120 colorectal cancer patients admitted to a hospital from January 2018 to January 2020 were selected．Immunohistochemical staining was performed on the colorectal cancer tissues and adjacent tissues of all patients,and the positivity rates of ZEB1 and LAMP5 were compared．The expression levels of ZEB1 and LAMP5 in colorectal cancer patients with different pathological characteristics were compared．All patients were followed up for 4 years and divided into two subgroups based on the follow-up results,namely the poor prognosis group（n=35）and the good prognosis group（n=85）．The general clinical characteristics and expression levels of ZEB1 and LAMP5 were compared between the two groups．Logistic regression analysis was used to evaluate the predictive value of ZEB1 and LAMP5 for the prognosis of colorectal cancer. Results The relative expression level of ZEB 1 and LAMP 5 in colorectal cancer tissues [（38.26±5.49）,（26.77±3.85）] and the positive rate of ZEB 1 and LAMP 5（86.67%,72.22%）were significantly higher than that of adjacent tissues [（15.46±2.54）,（8.04±1.59）,23.33%,15.56%],the contrast difference was statistically significant（t=41.280,χ²=25.437;t=49.255,χ²=16.071;P<0.05）．Relative ZEBI expression levels in different TNM stages [I-Ⅱstage（35.55±4.13）,Ⅲ-Ⅳstage（42.32±4.75）],lymph node metastasis[Yes（44.37±4.28）,No（35.84±3.77）],degree of tumor differentiation [hypodifferentiated（35.27±4.57）,and middle or high differentiated（29.04±2.55）],those differences were statistically significant（t=-8.254,P<0.001;t=9.227,P<0.001;t=-7.797,P<0.001）．The relative expression of LAMP 5 between different TNM stages [I-Ⅱstage（24.88±3.37）,Ⅲ-Ⅳstage（29.61±2.57）],lymph node metastasis [yes（30.72±2.19）,no（25.21±3.19）],degree of tumor differentiation [hypodifferentiated（24.57±3.62）,and middle or high differentiated（29.04±2.55）],the contrast was statistically significant（t=-8.254,P<0.001;t=9.227,P<0.001;t=-7.797,P<0.001）．There were no differences in gender,age,gross type,and tumor size between the good prognosis group and the poor prognosis group（P>0.05）,while there were differences in TNM stages,lymph node metastasis,tumor differentiation degrees,ratio of ZEB 1 and LAMP 5（P<0.05）．Logistic regression analysis showed that TNM stage,lymph node metastasis,ZEB 1 positive,and LAMP 5 positive were independent predictive factors of poor prognosis in colorectal cancer（P<0.05）. Conclusions ZEB1 and LAMP5 are highly expressed in colorectal cancer tissues and closely related to the occurrence and development of colorectal cancer．ZEB1 and LAMP5 are independent prognostic factors for colorectal cancer,and they have the potential to become therapeutic targets for colorectal cancer．

Objective To analyze the effects of bevacizumab and chemotherapy on the levels of four mismatch repair proteins（MSH2,MLHI,MSH6,PMS2）in patients with advanced colorectal cancer. Methods A total of 102 patients with advanced colorectal cancer from the Oncology Department of Suqian Traditional Chinese Medicine Hospital in Jiangsu Province from January 2022 to January 2024 were selected,and were divided into two groups according to the drawing method,namely the chemotherapy group and the combination group,with 51 patients in each group．The chemotherapy group received FOLFOX（calcium folinate+oxaliplatin+fluorouracil）regimen for chemotherapy,while the combination group received bevacizumab combined with FOLFOX regimen for treatment．Tumor control effect,immune function,and changes in MSH2,MLHI,MSH6,and PMS2 levels,and its incidence of adverse reactions were compared．Results The objective remission rate and disease control rate of the combined group were higher than those of the chemotherapy group（P<0.05）．After treatment,the CD4⁺,CD3⁺,CD8⁺ and CD4⁺/CD8⁺ values in the combination group were higher than those in the chemotherapy group,and those after treatment were lower than those before treatment in both groups（P<0.05）．After treatment,there were no significant differences in the deletion rates of MSH2,MLHI,MSH6,and PMS2 between the two groups of patients（P>0.05）,but there was a significant difference in their positive and negative expression．The positive rates of MSH2,MLHI,MSH6,and PMS2 in the combination group were lower than those in the chemotherapy group（P<0.05）．There was no significant difference in the incidence of adverse reactions between the two groups（P>0.05）．Conclusions Adding bevacizumab on the basis of chemotherapy has a significant anti-tumor effect on advanced colorectal cancer,improving its immune function．Although it cannot improve the mismatch repair protein defect in patients,it can assist in reducing its positivity rate and has high safety．

通过筛查和早期发现,可以降低结直肠癌（CRC）的发病率,有效切除肿瘤病变可以降低CRC的病死率。虽然对CRC的危险因素、发病机制和前体病变的了解已经取得进展,但最近年轻人群CRC发病率升高,原因尚不清楚。在过去十年中,出现了多种侵入性、半侵入性和非侵入性筛查方式。目前对结肠镜检查质量的重视提高了筛查的有效性,人工智能等影像新技术在肿瘤检测中的作用正在迅速显现。而且,CRC有效干预措施,如保肛治疗新术式、靶向治疗及免疫治疗领域的新进展,被证明可以提高CRC患者的生存率。该文旨在总结目前国内外CRC筛查方式和指南的证据,并综述CRC治疗领域的进展。

The incidence of colorectal cancer（CRC）can be reduced through screening and early detection．Effective resection of tumor lesions reduces mortality from CRC．Although progress has been made in understanding the risk factors,pathogenesis and precursor lesions of CRC,the reasons for the recent increase in the incidence of CRC in young adults are largely unknown．A variety of invasive,semi-invasive and non-invasive screening modalities have emerged in the last decade．The current emphasis on the quality of colonoscopy has improved the effectiveness of screening,and the role of new imaging technologies such as artificial intelligence in tumor detection is rapidly emerging．Moreover,there are effective interventions for CRC,such as new surgical modalities for anal preservation therapy,and new advances in the field of targeted therapy and immunotherapy,which have been shown to improve the survival rate of CRC．The aim of this article is to summarize the current evidence on CRC screening modalities and guidelines both nationally and internationally,and to provide an overview of advances in the field of CRC treatment．

Objective To analyze the mechanism of aspirin against colorectal cancer(CRC)by bioinformatic analysis. Methods DrugBank 5.1.5 was used to identify direct protein targets (DPTs) of aspirin. The protein-protein interaction (PPI) network of DPTs was constructed and involved signaling pathways were analyzed. CRC-associated gene expression datasets were downloaded from GEO database, and the top twenty differentially expressed genes with the highest degree were screened out as Hub genes. Common genes between the genes associated with the DPTs and the Hub genes of CRC were the potential targets of aspirin against CRC. The potential targets in TCGA database colon adenocarcinoma (COAD) samples were examined. GO functional enrichment analysis and KEGG signaling pathway analysis of the potential targets were performed. The potential targets of aspirin against CRC cells were verified by reverse transcription-polymerase chain reaction (RT-PCR) and western blot (WB). Results Eleven DPTs of aspirin were identified in DrugBank 5.1.5. KEGG signaling pathway showed that 6 genes (EDNRA, IKBKB, NFKB2, NFKBIA, PTGS2, TP53) were associated with the occurrence and development of CRC. By intersecting 20 Hub genes of CRC with genes associated with the DPTs of aspirin, it was found that 5 genes (CDK1, AURKA, CCNB1, MAD2L1, TPX2) might be the potential targets of aspirin against CRC. They were all up-regulated in TCGA-COAD samples, and the gene functions were mainly enriched in cell cycle regulation. The results of RT-PCR and WB showed that aspirin could down-regulate the mRNA and protein expression levels of CDK1, AURKA, CCNB1, MAD2L1 and TPX2 in human colon cancer cells respectively. Conclusion CDK1, AURKA, CCNB1, MAD2L1 and TPX2 could be potential targets of aspirin against CRC by affecting the progress of cell cycle regulation.

目的 评估中性粒细胞与淋巴细胞比值(NLR)在晚期结直肠癌(CRC)患者化疗疗效及预后的意义。方法 回顾性收集2016年1月—2019年4月期间接受以奥沙利铂为基础的标准一线化疗的晚期不可切除结直肠癌患者50例临床病历资料,并在2个化疗周期后评估化疗疗效;根据入组患者化疗前血液学数据计算中性粒细胞与淋巴细胞比值(NLR),运用受试者工作特征曲线确定的NLR最佳截断值,将患者分为高NLR(≥3.785) 组和低NLR(＜3.785) 组,比较高、低NLR与临床病理特征、化疗疗效及无进展生存期(PFS)、总生存期(OS)差异;采用COX回归分析模型分析影响晚期结直肠癌患者PFS、OS的因素。结果 高、低NLR两组肿瘤分化程度(P=0.030)、ECOG评分(P=0.003)、CEA(P=0.011)、CA19-9(P=0.047)比较,差异有统计学意义;高低NLR两组间化疗疗效比较,差异有统计学意义(P＜0.001),高NLR组化疗疗效较差;两组中位PFS分别为3.44个月和12.84个月,差异有统计学意义(χ²=39.730,P＜0.001),两组中位OS分别为7.59个月和22.32个月,差异有统计学意义(χ²=40.505,P＜0.001);Cox回归分析提示NLR高低、CEA水平是PFS、OS的独立预后因素(P＜0.05)。结论 高水平NLR与晚期结直肠癌患者化疗疗效不佳和预后不良相关,可作为其化疗疗效及预后监测的指标。

Objective To evaluate the value of neutrophil-lymphocyte ratio (NLR) in the chemotherapy curative effect and prognosis of patients with advanced colorectal cancer (CRC). Methods Retrospective collection of clinical data from 50 patients with advanced unresectable colorectal cancer who received oxaliplatin-based standard first-line chemotherapy between January 2016 and April 2019. Chemotherapy curative effect was evaluated following 2 chemotherapy cycles. Calculation of neutrophil to lymphocyte ratio (NLR) based on pre-chemotherapy hematology data. The receiver operating characteristic curve was used to determine the optimal cutoff value of NLR,according to patients who were divided into groups of high NLR(NLR≥3.785)and low NLR(NLR≥3.785).The differences between high and low NLR and clinicopathological features, efficacy of chemotherapy, progression-free survival (PFS), and total survival (OS) were compared. COX regression analysis mode was used to analysis of factors affecting PFS and OS in patients with advanced colorectal cancer. Results The differences in tumor differentiation (P=0.030), ECOG score (P=0.003), CEA (P=0.011), CA19-9 (P=0.047) in the high and low NLR groups were statistically significant. The differences in chemotherapy between the two groups was statistically significant (P<0.001), and the high NLR group was less effective. The median PFS of the high and low NLR groups were 3.44 months and 12.84 months, respectively, and the difference was statistically significant (χ²=39.730, P<0.001). The median OS of the high and low NLR groups was 7.59 months and 22.32 months, respectively, and the difference was statistically significant (χ²=40.505, P<0.001). Cox regression analysis suggested that NLR levels and CEA levels were independent prognostic factors for PFS and OS(P＜0.05). Conclusion High-level NLR is associated with poor chemotherapy response and poor prognosis in patients with advanced colorectal cancer, and was used as an indicator of chemotherapy efficacy and prognosis.
