结直肠癌（CRC）是全球第三大最常见的癌症，也是癌症相关死亡的第二大常见原因。结直肠癌肝转移（CRLM）是导致CRC患者死亡的主要原因，根治性肝切除术是目前有望治愈CRLM的唯一途径，但大部分患者不能进行根治性肝切除术。通过早期发现并进行针对性干预，能够改善患者的治疗效果及预后。文章通过综述CRLM的发病机制、诊疗现状及最新纳米诊疗方法，为深入探索高效诊疗方法提供思路。

      Colorectal cancer（CRC）is the third most common cancer and the second most common cause of cancer-related death worldwide．Colorectal cancer liver metastases（CRLM）are the leading cause of death in patients with CRC．Radical hepatectomy is the only way to cure CRLM so far，while most patients cannot undergo radical hepatectomy．CRLM treatment efficacy and prognosis can be improved by early diagnosis and specialized intervention．This paper reviews the pathogenesis，diagnosis，and treatment status of CRLM and the latest nano-diagnosis and treatment methods so as to provide ideas for in-depth exploration of efficient diagnosis and treatment methods．

       炎症性肠病（IBD）是一种以反复腹痛、腹泻、血便和体重降低为主要表现的慢性特发性性疾病，主要分为溃疡性结肠炎与克罗恩病两种类型。近年来，IBD的患病率随着城市化和工业化进展迅速升高，给中国和全球的公共健康带来沉重的负担。随着人类基因组技术的发展，越来越多的证据表明，遗传学因素在IBD发病过程中起着不可或缺的作用。在亚欧人群中，通过大规模全基因组关联研究现已明确了320个IBD易感基因位点。IBD易感基因在影响机体的细胞代谢、免疫功能调节、肠道上皮屏障和微生物清除等多个方面发挥着重要作用。本文就IBD相关易感基因及其多态性的研究进展进行综述，从基因层面揭示IBD发病的分子机制，并对探索IBD因人而异的个性化治疗方案提供帮助。

    Inflammatory bowel disease（IBD）is a chronic idiopathic disease characterized by recurrent abdominal pain，diarrhea，bloody stools，and weight loss．Ulcerative colitis and Crohn’s disease represent the two main types of IBD．In recent years，the prevalence of IBD has increased rapidly with the advancement of industrialization，imposing a heavy burden on public health in China and globally．Currently，with the development of genomics，a growing body of evidence suggests that genetic factors play an indispensable role in the pathogenesis of IBD．In the Eurasian population，320 IBD susceptibility gene loci have been identified through large-scale genome-wide association studies．IBD susceptibility genes play a crucial role in various aspects affecting cellular metabolism，immune function regulation，intestinal epithelial barrier，and microbial clearance．This article reviews the susceptibility genes and their polymorphisms associated with IBD，revealing the molecule mechanisms of IBD from gene perspectives and contributing to the development of personalized treatment strategies tailored to individual IBD patients．

       根据美国国家胆固醇教育计划成人组第三次报告NECP-ATPⅢ会议定义，当男性年龄＜55岁，女性年龄＜65岁诊断为冠状动脉粥样硬化性心脏病（冠心病）时即为早发冠心病（pCAD）。作为冠心病的特殊类型之一，pCAD发生多伴明显家族史。近年来随着早发冠心病患者人数呈明显上升趋势，且单核苷酸多态性（SNP）研究和全基因组关联研究的迅速发展，与早发冠心病相关的基因多态性研究成为热点。笔者利用多个文献数据库检索国内外相关文献，对近年早发冠心病的基因多态性研究进展予以综述，并尝试归纳总结出新的重点研究方向。

Long non-coding RNA（lncRNA）is a class of transcripts with a length of more than 200 nucleotides．It is involved in the occurrence and development of tumors and plays an important role by regulating the expression and function of DNA,RNA and protein．In recent years,lncRNA has become a new research direction for early diagnosis and prognosis of malignant tumors．As a newly discovered lncRNA,linc-UBC1 is abnormally highly expressed in a variety of malignant tumors such as lung cancer,gastric cancer,colorectal cancer,cervical cancer,ovarian cancer,and esophageal squamous cell carcinoma．It can promote the proliferation,migration,invasion,cell cycle progression,cell apoptosis and EMT of tumor cells by acting as a competing endogenous RNA（ceRNA）and participating in signaling pathways．High expression of linc-UBC1 can increase the drug resistance of malignant tumors,and its expression level is positively correlated with tumor stage,lymph node metastasis and distant metastasis of primary tumors．linc-UBC1 is expected to become a new biomarker,prognostic predictor and therapeutic target for many malignant tumors,while its specific regulatory mechanism is still in the early stage of research and needs further in-depth study．This article reviews the current research progress of linc-UBC1 in the occurrence and development of malignant tumors．

       目的   研究核磁共振（MR）引导的海马保护技术应用于小细胞肺癌全脑放射治疗（放疗）的效果。方法  对确定行全脑放疗的30例小细胞肺癌脑转移患者，行常规放疗CT定位后以定位体位行全头颅MR平扫，将计算机断层扫描（CT）和MR的T1加权像在Monaco 5.1计划系统上进行精准融合，勾画全脑放疗及海马区域，在海马区域三维方向上分别外扩5、15 mm作为海马与计划靶区之间的剂量跌落，每一例患者在Monaco 5.1计划系统上按照不保护海马组织以及外扩5、15 mm进行保护设计3个容积旋转调强技术（VMAT）放疗计划，观察海马组织的平均及最大放疗剂量。结果  增加保护海马组织之后，3个放疗计划的D100均≥95%，每例的3个放疗计划间D100比较差异无统计学意义（P＞0.05）；设置外扩5、15 mm的剂量跌落区后，左、右海马的平均剂量、最大剂量均明显降低，而且3个放疗计划的海马平均剂量、最大剂量之间对比差异有统计学意义。结论   小细胞肺癌脑转移患者进行全脑放疗时，利用MR引导的海马保护技术并设置外扩15 mm的剂量跌落区，能够显著降低海马的剂量，达到保护目的。

       Objective  To explore the application of MR guided hippocampal avoidant whole brain radiotherapy（WBRT）for small cell lung cancer（SCLC）．Methods  Thirty SCLC patients with brain metastases who underwent WBRT were enrdled．After routine CT localization was performed，and a head MR was performed in a the same position．T1 weighted images of MR and CT images were accurately fused on the Monaco 5.1 planning system．The entire brain tissue and hippocampus region were delineated．The dose drop areas between the hippocampusand the planned target area were expanded 5mm and 15mm in the three-dimensional direction of the hippocampus，respectively．Three volumetric modulated arc therapy（VMAT）radiotherapy plans were designed for each patient on the Monaco 5.1 planning system based on whether the hippocampal tissue was avoid．The average and maximum doses of hippocampal tissue were observed．Results  After the avoidance of hippocampal tissue，the D100 of the three radiotherapy plans reached ≥95%，and there was no significant difference in D100 between the three radiotherapy plans in each case．After setting dose drop areas of 5mm and 15mm for external expansion，the average and maximum doses of the left and right hippocampus were significantly reduced，and there was a significant difference in the comparison between the average and maximum doses in the hippocampus of the three radiotherapy plans．Conclusions  MR guided hippocampal avoidant technology and the setting of a 15 mm dose drop area can significantly reduce the dose to the hippocampus in patients with SCLC undergo whole brain radiotherapy．

      目的   探讨载脂蛋白E（ApoE）基因多态性与卒中后认知障碍的相关性，即大动脉粥样硬化型脑梗塞的严重程度。方法   采用病例——对照研究的方法，收集九江学院附属医院神经内科的100例急性缺血性脑卒中且病因分型为大动脉粥样硬化型患者（脑梗死组）和50例性别、年龄匹配的非缺血性脑卒中患者（对照组）。检测患者的 ApoE 基因型、血脂、美国国立卫生院卒中量表（NIHSS）、卒中后6个月简易智力状态检查量表（MMSE）等，采用多因素方差分析等统计学方法分析他们之间的关联性。结果  ApoE 3/4基因型频率与Ɛ3、Ɛ4等位基因频率，在脑梗死组别中高于对照组（P＜0.05）。同时，携带Ɛ3等位基因患者的低密度脂蛋白水平高于携带Ɛ2、Ɛ4等位基因的患者；进一步分析发现含Ɛ3等位基因的脑梗死患者NIHSS评分更高、卒中后认知障碍更严重（P＜0.05）。结论  ApoE基因型为Ɛ3/4、等位基因Ɛ3、Ɛ4更易罹患大动脉粥样硬化型脑梗死，提示该基因型是脑梗死的易感基因，脑梗死后认知障碍患者Ɛ3等位基因的频率较高，可能是卒中后认知障碍的易感因素。
