约10%~30%的新发结直肠癌患者会出现急性肠梗阻，传统急诊手术治疗存在术后并发症高、死亡率高、生存质量低等不足。肠道支架置入联合限期手术作为一种新型治疗策略，展现出显著优势。肠道支架可迅速解除梗阻，改善患者症状，降低手术风险，为肿瘤微创切除创造条件，同时为新辅助化疗提供可能，但其潜在并发症如出血、移位、再梗阻及肠穿孔等也不容忽视，且长期安全性及对肿瘤结局的影响尚不明确。文章综述了肠道支架治疗梗阻性结直肠癌的治疗现状、争议及研究进展，旨在为临床研究和实践提供参考依据。

    Approximately 10% to 30% of patients with newly diagnosed colorectal cancer present with acute intestinal obstruction．Traditional emergency surgical intervention is characterized by high rates of postoperative complications，elevated mortality，and diminished quality of life．Combined stent and curative elective surgery（CSCES）has emerged as a novel therapeutic strategy，exhibiting significant clinical benefits．Intestinal stenting can rapidly alleviate obstruction，thereby improving patient symptoms，reducing surgical risks，and facilitating minimally invasive tumor resection．Additionally，it provides an opportunity for neoadjuvant chemotherapy．However，potential complications，including bleeding，stent migration，recurrent obstruction，and intestinal perforation，must be carefully considered．Moreover，the long-term safety and impact on oncologic outcomes remain to be elucidated．This review aims to provide a comprehensive overview of the current status，controversies，and recent advancements in the use of intestinal stents for the treatment of obstructive colorectal cancer，with the goalof informing clinical research and practice．

      目的 探讨血清乳酸脱氢酶（LDH）在中晚期肝癌患者接受靶向联合免疫治疗后的预后预测价值。方法 选取2022年1月—2024年8月在莆田学院附属医院肿瘤内科经病理和影像学检查确诊的中晚期肝癌患者作为研究对象。从医院的电子病历系统中收集患者的基线资料，随访截止2025年8月，并记录随访结果，包括患者的疾病缓解情况和死亡情况，以及无疾病进展生存期（PFS）、总生存期（OS）。采用Kaplan-Meier方法绘制不同基线LDH水平患者的OS生存曲线，并通过Log-rank检验比较生存曲线。同时，运用多因素Cox比例风险回归分析探讨影响中晚期肝癌患者在接受靶向联合免疫治疗后OS的相关因素。结果 结果显示，在50例肝癌患者中，基线LDH低于200 U/L的有15例，而高于200 U/L的有35例。与基线LDH＜200 U/L组相比，基线 LDH≥200 U/L患者PFS、OS更短，差异均有统计学意义（χ²分别为5.51、15.6，P值分别为0.019、0.017）。治疗8周后，与LDH降低患者相比，LDH升高患者OS更短，差异有统计学意义（χ²=13.2，P=0.04）。多因素Cox比例风险回归分析结果表明，基线LDH水平超过200 U/L是中晚期肝癌患者接受靶向联合免疫治疗后OS的影响因素［P=0.035，HR（95%CI）=5.03（1.12，22.54）］。结论 基线LDH水平较低的患者表现出更好的OS。基线LDH水平可以作为预测中晚期肝癌患者在接受靶向联合免疫治疗时预后的指标。 

   Objective To evaluate the prognostic significance of serum lactate dehydrogenase（LDH）levels in patients with advanced hepatocellular carcinoma（HCC）undergoing targeted therapy combined immunotherapy．Methods Patients diagnosed with advanced HCC were selected in Putian College Affiliated Hospital from January 2022 to August 2024，diagnosed with pathological and imaging examinations results．Patient baseline data were collected from the hospital’s electronic medical records，with follow-up extending until August 2025．We documented outcomes such as disease response and mortality，along with progression-free survival（PFS）and overall survival（OS）．Kaplan-Meier survival curves were constructed based on baseline LDH levels，and the Log-rank test was employed for comparison．Additionally，multivariate Cox proportional hazards regression analysis was conducted to identify factors influencing OS in patients receiving targeted therapy combined immunotherapy．Results Among the 50 patients，15 had baseline LDH levels below 200 U/L，while 35 had levels above．Patients with baseline LDH≥200 U/L had significantly shorter PFS and OS than those with baseline LDH ＜200 U/L（χ²=5.51 and 15.6 for PFS and OS，respectively；P=0.019 and 0.017，respectively）．After 8 weeks of treatment，patients with increased LDH had significantly shorter OS compared with patients with decreased LDH（χ²=13.2，P=0.04）．Multivariate Cox proportional hazards regression analysis indicated that a baseline LDH level exceeding 200 U/L is an independent prognostic factor for OS in patients with intermediate to advanced HCC receiving targeted therapy combined with immunotherapy（P=0.035，HR 5.03［1.12，22.54］）．Conclusions Patients with lower baseline LDH levels demonstrated better OS，suggesting that baseline LDH can serve as an important prognostic indicator for advanced HCC patients undergoing targeted combined immunotherapy．

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．

目的 分析贝伐珠单抗与化疗对晚期结直肠癌患者4种错配修复蛋白（MSH2、MLHI、MSH6、PMS2）水平影响。方法 选择2022年1月—2024年1月江苏省宿迁市中医院肿瘤科102例晚期结直肠癌患者,按抽签法分成两组,即化疗组及联合组,各51例。化疗组应用FOLFOX（亚叶酸钙+奥沙利铂+氟尿嘧啶）方案进行化疗,联合组采取贝伐珠单抗联合FOLFOX方案治疗。对比其肿瘤控制效果、免疫功能及MSH2、MLHI、MSH6和PMS2水平变化,并对比组间不良反应发生率。结果 联合组客观缓解率、疾病控制率高于化疗组（P<0.05）;治疗后联合组患者CD4⁺、CD3⁺、CD8⁺、和CD4⁺/CD8⁺数值高于化疗组,且两组治疗后均低于治疗前（P<0.05）;治疗后两组患者MSH2、MLHI、MSH6和PMS2缺失率对比无统计学意义（P>0.05）,但其阳性、阴性表达情况对比差异有统计学意义,联合组MSH2、MLHI、MSH6和PMS2阳性率低于化疗组（P<0.05）;两组不良反应发生率对比差异无统计学意义（P>0.05）。结论 对晚期结直肠癌在化疗基础上增加贝伐珠单抗抗肿瘤效果显著,改善其免疫功能,虽无法改善患者错配修复蛋白缺损,但可辅助降低其阳性率,且不影响安全性。

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 study the clinical efficacy of endoscopic cold snare resection using water injection method in 5-10 mm pedunculated colorectal polyps. Methods A total of 120 patients with 5-10 mm sessile colorectal polyps admitted to Yangchun Traditional Chinese Medicine Hospital were selected as the research subjects．A total of 246 polyps were enrolled,and the patients were divided into two groups based on the different methods of endoscopic resection：underwater cold snare polypectomy（UCSP）and conventional cold snare polypectomy（CCSP）,with 60 patients enrolled in each group．Compare the location,size,postoperative pathological diagnosis,complete polypectomy rate,postoperative pathological depth,polyp recovery rate,surgical time,instantaneous intraoperative bleeding rate,delayed perforation rate,delayed bleeding rate,surgical time,Boston and VAS scores between two groups. Results Two groups of polyp locations,polyp size,postoperative pathological diagnosis,complete polyp resection rate,polyp recovery rate,the instantaneous intraoperative bleeding rate,delayed perforation rate,delayed bleeding rate,and Boston score,all of above were not significant different（P>0.05）;the postoperative pathological depth in the UCSP group[（8.8±0.5）mm] was significantly greater than that in the CCSP group[（5.9±0.4）mm]（P<0.01）,and the surgical time in the CCSP group[（21.3±2.4）min] was shorter than that in the UCSP group[（25.7±1.1）min]（P<0.01）． The VAS score in the UCSP group（2.6±0.7）was significantly better than that in the CCSP group（2.9±0.3）（P<0.001）. Conclusions The underwater cold snare polypectomy can achieve good therapeutic results in patients with 5-10 mm sessile colorectal polyps．Further pathological evaluation of postoperative can obtain deeper of myomucosal resection．Although the UCSP group has a longer surgical time,the incidence of postoperative abdominal pain is lower．

目的 观察低浓度布比卡因联合全身麻醉在腹腔镜下直肠癌根治术中的应用及对患者体征及苏醒质量的影响。方法 选择2020年1月—2021年6月在信阳一五四医院实施腹腔镜镜下直肠癌根治术治疗的126例直肠癌患者为研究对象,通过抽签法对患者进行分组,将其中63例列为全麻组,术中单纯实施全身麻醉,其余63例列为联合组,术中采用低浓度布比卡因联合全身麻醉,比较两组患者体征变化情况,苏醒质量,麻醉相关不良反应,并开展为期1.5年的随访,评估两组患者远期生存质量。结果 联合组术中、术后的心率、平均动脉压均低于全麻组（P<0.05）;术后,联合组的Steward麻醉苏醒评分略低于全麻组、麻醉恢复室停留时间略高于全麻组（P>0.05）;但联合组的视觉模拟疼痛评分、镇静评分均低于全麻组（P<0.05）;联合组的麻醉相关不良反应发生率略高于全麻组（P>0.05）;随访期间,联合组的肠癌患者生存质量测定量表各维度评分均高于全麻组（P<0.05）。结论 低浓度布比卡因联合全身麻醉的麻醉效果更加平稳、安全性高。

Objective To observe the application of low concentration bupivacaine combined with general anesthesia in laparoscopic radical resection of rectal cancer and its effect on the physical signs and recovery quality of patients. Methods In this study,126 rectal cancer patients who underwent laparoscopic radical resection of rectal cancer in Xinyang 154th Hospital from January 2020 to June 2021 were selected as the research subjects．The patients were divided into groups by drawing lots．Among them,63 patients were included in general anesthesia group,and the rest 63 patients were included in combined group．Low-concentration bupivacaine combined with general anesthesia was used in combined group during the operation．The changes of physical signs and the quality of recovery were compared between the two groups．Anesthesia related adverse events,and the long-term quality of life of the two groups of patients was evaluated through one-year and a half follow-up. Results The heart rate and mean arterial pressure during and after surgery in the combined group were lower than those in the general anesthesia group（P<0.05）．After surgery,the Steward anesthesia recovery score of the combined group was slightly lower than that of the general anesthesia group,and the PACU stay time was slightly higher than that of the general anesthesia group（P>0.05）．However,the VAS score and Richmond Agitation-Se dation Scale score of the combined group were lower than those of the general anesthesia group（P<0.05）．The incidence of anesthesia related adverse reactions in the combination group was slightly higher than that in the general anesthesia group（P>0.05）．During the follow-up period,the FACT-C scores of all dimensions in the combination group were higher than those in the general anesthesia group（P<0.05）. Conclusions The anesthesia effect of low concentration bupivacaine combined with general anesthesia is significant and safe．
