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．

实体瘤对免疫治疗应答非常有限,因此,如何有效提升肿瘤免疫治疗的疗效,已成为当前肿瘤免疫治疗领域亟待解决的关键难题与挑战。髓系来源抑制性细胞（MDSCs）的趋化募集及其所介导的肿瘤免疫逃逸机制,是制约实体瘤免疫治疗效果的核心因素之一。文章深入探讨了MDSCs的起源、表型特征、其介导肿瘤免疫逃逸的具体机制,以及当前针对MDSCs的靶向治疗策略与将MDSCs靶向疗法与肿瘤免疫治疗相结合的最新研究进展。此外,文章还系统性地分析了靶向MDSCs联合免疫治疗策略所面临的关键挑战,并据此提出了MDSCs的精准靶向策略。这一策略旨在精确激活抗肿瘤免疫反应,为癌症患者提供更为个性化、高效的治疗方案,从而开启肿瘤免疫治疗领域的新纪元,为癌症治疗策略的创新与发展贡献力量。

Solid tumors exhibit a very limited response to immunotherapy．Consequently,effectively enhancing the therapeutic efficacy of tumor immunotherapy has emerged as a critical challenge and problem that urgently needs to be addressed in tumor immunotherapy．The chemotaxis and recruitment of myeloid-derived suppressor cells（MDSCs）and the tumor immune evasion mechanisms mediated by them are one of the core factors that significantly restrict the efficacy of immunotherapy for solid tumors．In this review,we discuss the origins and phenotypic characteristics of MDSCs,the specific mechanisms by which they mediate tumor immune evasion,as well as current targeted therapeutic strategies for MDSCs and the latest research progress in combining MDSC-targeted therapy with tumor immunotherapy．Furthermore,we have systematically analyzed the key challenges faced by the combination of MDSC-targeted and immunotherapy strategies,and accordingly proposed a precise targeting strategy for MDSCs．This strategy aims to precisely activate anti-tumor immune responses,providing more personalized and efficient treatment options for cancer patients,thereby opening a new era in tumor immunotherapy and contributing to the innovation and development of cancer treatment strategies．

CCAAT增强子结合蛋白A（CEBPA）是调节血液发育过程中髓系分化和造血干祖细胞活性的关键转录因子之一。CEBPA基因突变常见于急性髓系白血病（AML）中,最近研究表明CEBPA bZIP框内单位点和经典双等位基因突变AML患者均具有类似的临床特征,已被单独划分为AML亚群。CEBPA bZIP框内突变而非传统的双等位CEBPA基因突变成为AML良好预后的分子指标,表明其在AML疾病进展和治疗预后中的重要性和特殊性。本文将从CEBPA蛋白在血液系统中的功能、CEBPA bZIP框内突变AML的临床特征与分子作用机制、以及伴CEBPA突变AML的治疗现状等方面进行综述,为进一步研究CEBPA bZIP框内突变在AML中的致病性和精准治疗新药物开发提供参考。

CCAAT enhancer-binding protein A（CEBPA）is one of the key transcription factors regulating myeloid differentiation and hematopoietic stem/progenitor cell maintenance during hematopoiesis．CEBPA gene mutations are commonly found in acute myeloid leukemia（AML）．Recent studies have demonstrated that AML patients haboring single CEBPA bZIP in-frame mutations or classical bi-allelic CEBPA mutations show similar clinical features and it has been individually classified as AML subgroup．Additionally,it is CEBPA bZIP in-frame mutations rather than the traditional biallelic CEBPA mutations that have emerged as a molecular indicator of favorable prognosis for clinical AML management,suggesting its importance and specificity in AML disease progression and therapeutic prognosis．Here,we reviewed serval aspects including the hematopoietic function of CEBPA protein,the clinical features and molecular mechanisms of AML with CEBPA bZIP in-frame mutations,and the current status of the treatment of AML with CEBPA mutations,which will provide a reference for further study of the pathogenicity of CEBPA bZIP in-frame mutations in AML and the development of new drugs for precision therapy．
