      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。
       Objective  To  explore the  relationship  between ApoE  gene  polymorphisms  and  post-stroke  cognitive  impairment,the severity of large artery atherosclerotic cerebral infarction.Methods  A  case-control research  study was conducted,gathering  data from  100 individuals  diagnosed with large artery atherosclerotic cerebral infarction according to the TOAST classification,who admitted to the Neurology Department of the Affiliated Hospital of Jiujiang University.Additionally,50 non-ischemic stroke patients,matched for gender and age,were included as the control group.The patients were assessed for ApoE genotype,blood lipid,NIHSS,and MMSE scale at 6 months post-stroke,and statistical methods were used to analyze their associations.  Results  Significant differences were observed in the ApoE 3/4 genotype frequency and Ɛ3、Ɛ4 allele frequency between patients with cerebral infarction and the control group,with a notably higher incidence of cerebral infarction in the former.Furthermore,patients carrying the Ɛ3 allele exhibited significantly higher LDL levels than those carrying Ɛ2 or Ɛ4.The analysis also revealed that patients with the Ɛ4 allele experienced higher NIHSS and severer post-stroke cognitive impairment.Conclusions  The findings suggest that the ApoE genotype Ɛ3/4 and allele Ɛ3、Ɛ4 may predispose individuals to develop large atherosclerotic cerebral infarction,indicating a susceptibility gene for cerebral infarction.Additionally,the Ɛ3 allele was associated with a higher frequency of cognitive deficits after cerebral infarction,implying that it may be a predisposing factor for post-stroke cognitive impairment.

MR 引导的海马保护用于小细胞肺癌全脑放疗

Hippocampal avoidant whole brain radiotherapy guided by MR of small cell lung cancer

:330-337
 
       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。  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.

lncRNA linc-UBC1 在恶性肿瘤发生发展中的作用研究进展

Research progress of long non-coding RNA linc-UBC1 in the development of malignant tumors

:323-329
 
      长链非编码RNA(lncRNA)是一类长度大于200个核苷酸转录本,通过调控DNA、RNA及蛋白质的表达和功能,参与肿瘤发生、发展并发挥重要作用的RNA,近年来lncRNA成为恶性肿瘤早期诊断和预后标志物研究新的关注方向。Linc-UBC1作为一种新发现的lncRNA,在多种恶性肿瘤如肺癌、胃癌、结直肠癌、宫颈癌、卵巢癌、食管鳞癌等中异常高表达,可通过作为竞争性RNA(ceRNA)、参与信号通路等促进肿瘤细胞的增殖、迁移、侵袭、细胞周期进展、细胞凋亡和上皮间充质转化(EMT)等过程;高表达的linc-UBC1能够增加恶性肿瘤的耐药性,其表达水平与肿瘤分期、淋巴结转移和原发肿瘤远处转移呈正相关;linc-UBC1有望成为许多恶性肿瘤的新型的生物标志物、预后预测因子和治疗靶点,但其具体的调控机制仍处于研究的早期阶段,有待进一步深入研究。文章就目前linc-UBC1在恶性肿瘤发生和发展中的作用研究进展进行综述。
       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.
