融合基因是指两个独立基因的编码区首尾相连所形成的且置于同一套调控序列控制的产物,研究表明许多癌症的发生与融合基因存在密切的联系。融合基因可作为癌症治疗的靶点,在癌症诊断及治疗领域中融合基因的研究具有重要意义。部分融合基因驱动癌症的机制已被初步揭示,但是有些真实存在的在肿瘤发生发展过程中有重要意义的融合基因由于工具和实验技术限制还未被发现。因此,对融合基因的分析预测研究方法逐渐成为关注的热点之一。本文探讨了目前常用的关于融合基因的分析工具及方法,为融合基因在癌症中的研究提供思路。

Fusion genes are the products of two independent genes whose coding regions are linked and controlled by the same set of regulatory sequences．Studies have shown that many cancers are closely linked to gene fusions．Fusion genes can be used as targets for cancer therapy,and the study of fusion genes is of great importance in cancer diagnosis and treatment．Some of the mechanisms of fusion genes driving cancer have been initially revealed,but there are more fusion genes which are important in the process of tumor development have not been discovered due to the limitation of tools and experimental techniques．Therefore,the analysis and prediction methods of fusion genes are becoming a hot topic of interest．In this paper,we discuss the commonly used analytical tools and methods on fusion genes to provide ideas for the study of fusion genes in cancer．

Objective To investigate the correlation between vertebrobasilar artery stenosis and serum biochemical indexes in patients with posterior circulation cerebral infarction（PCCI）．Methods One hundred patients with PCCI admitted to our hospital were selected as the study objects,and the clinical data of all patients were retrospectively analyzed．The patients were divided into unstable plaque group（n=35）,stable plaque group（n=36）and no plaque group（n=29）according to the degree of vertebrobasilar artery stenosis．The general clinical conditions,serum levels of neurocytokines and inflammatory factors of the patients were compared,the correlation between vertebrobasilar artery stenosis and serum biochemical indicators in patients with PCCI was analyzed．Results The recurrence and NIHSS score of the 3 groups were significantly different,the unstable plaque group was significantly higher than the other 2 groups（P<0.05）,but there was no significant difference between the stable plaque group and the no plaque group（P>0.05）．The levels of brain-derived neurotrophic factor（BDNF）,neuron-specific enolase（NSE）and central nerve specific protein（S100β）in the three groups were significantly different．BDNF in unstable plaque group was lower than that in stable plaque group and no plaque group,while NSE and S100β in unstable plaque group were higher than that in stable plaque group and no plaque group（P<0.05）．There was no significant difference between stable plaque group and no plaque group（P>0.05）．The levels of serum C-reactive protein（CRP）,interleukin-37（IL-37）,tumor necrosis factor-α（TNF-α）,vascular cell adhesion molecule-1（VCAM-1）,intercellular adhesion molecule-1（ICAM-1）and human cartilage glycoprotein 40（YKL-40）in 3 groups were significantly different．The unstable plaque group was higher than the other two groups（P<0.05）,but there was no significant difference between the stable plaque group and the no plaque group（P>0.05）．Pearson Line correlation analysis showed that vertebrobasilar artery stenosis was negatively correlated with BDNF,and positively correlated with NSE,S100β,CRP,IL-37,TNF-α,VCAM-1,ICAM-1,YKL-40（P<0.05）．Multivariate Logistic regression analysis showed that BDNF,NSE,ICAM-1 and YKL-40 were independent risk factors for vertebrobasilar artery stenosis（P<0.05）．Conclusions The more severe degree of vertebrobasilar artery stenosis in patients with PCCI,the higher recurrence rate and more serious the impact on the neurological function of patients．At the same time,the levels of serum related neurocytokines and inflammatory factors were significantly related to the severity of vertebrobasilar artery stenosis．BDNF,NSE,ICAM-1 and YKL-40 can be used as important indicators to predict the severity of vertebrobasilar artery stenosis in patients with PCCI．Therefore,monitoring the patient’s serum biochemical indicators of angiography can provide reference for clinical diagnosis and prognosis judgment．

Objective To evaluate the outcome of aneurysm diameter and volume,and the role of endoleak after endovascular aneurysm repair of abdominal aortic aneurysm．Methods The clinical and imaging data from 83 patients who underwent endovascular repair of abdominal aortic aneurysm in our hospital from 2015 to 2020 were retrospectively analyzed．The maximum aneurysm diameter and volume were measured at the preoperative and postoperative follow-up time points．CT was used to evaluate the incidence of postoperative leakage．The aneurysm（diameter/volume）expansion/shrinkage and aneurysm（diameter/volume）stability were defined．Patients were divided into different groups according to the maximum preoperative aneurysm diameter and the incidence of postoperative endoleak,and the outcomes of aneurysm diameter and volume were compared at established follow-up points．Results The mean follow-up time was 24（10-62）months．There were no statistically significant differences in postoperative aneurysm volume and diameter at follow-up points between the patients with aneurysm diameter <50 mm and patients with aneurysm≥50 mm．There were statistically significant differences in postoperative aneurysm volume between the patients with postoperative endoleak and patients without postoperative endoleak（P<0.05）．However,there were no statistically significant differences in postoperative diameter between the two groups．Conclusions The changes of aneurysm volume and diameter were not closely related,and the detection of aneurysm volume can help to find the aneurysm changes with no obvious diameter changes．The postoperative endoleak after endovascular aneurysm repair may be one of the factors leading to aneurysm enlargement．
