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．

目的 从炎症反应和肠道屏障两个方面探究五味苦参肠溶胶囊对葡聚糖硫酸钠（DSS）诱导的小鼠结肠炎的治疗作用。方法 6~8周龄雄性BALB/c小鼠被随机分为3组,分别为正常组、急性肠炎模型组和五味苦参组。急性肠炎模型组和五味苦参组小鼠予含有3% DSS的饮用水1周诱导急性结肠炎,其后急性肠炎模型组予PBS灌肠,五味苦参组予五味苦参肠溶胶囊制备为灌肠液灌肠。每天称量小鼠体质量,观察大便性状及血便情况,第8天处死小鼠,取结肠组织检测炎症细胞因子和肠屏障因子。结果 与正常组相比,急性肠炎模型组肠道炎症明显,五味苦参组有效缓解肠道炎症和有利于肠上皮屏障修复。表现为五味苦参灌肠液有效缓解小鼠体质量下降,具有较低的DAI评分,有较好的组织学表现,其结肠组织IL-1β,IL-6和TNF-α的相对表达下降,Occludin和ZO-1的相对表达增加（P<0.05）。结论 五味苦参肠溶胶囊制备的灌肠液可减轻DSS诱导的小鼠急性结肠炎。

Objective To explore the therapeutic effect of five-flavor sophora flavescens enteric-coated capsules（FSEC）on dextran sulphate sodium（DSS）-induced colitis in mice from inflammatory response and intestinal barrier．Methods Male BALB/c mice aged 6-8 weeks were randomly divided into three groups,namely normal group,acute colitis group and FSEC group．The mice in acute colitis group and FSEC group were given drinking water containing 3% DSS for one week to induce acute colitis,and then they were given PBS enema or FSEC enema respectively．The mice were administered daily,including weight loss,the stool properties and bloody feces．The mice were sacrificed on the 8th day,and the colon tissue was collected to detect inflammatory cytokines and intestinal barrier cytokines．Results Compared with the normal group,the intestinal inflammation in the acute colitis group was obvious,however the FSEC effectively relieved intestinal inflammation and facilitated the intestinal epithelial barrier repair．It showed that FSEC enema effectively relieved weight loss and had a lower disease activity index score．In addition,FSEC enema group had better histological appearance．Compared to acute colitis group,the relative expression of IL-1β,IL-6 and TNF-α in colon tissue decreased,and the relative expression of Occludin and ZO-1 significantly increased in FSEC group（P<0.05）．Conclusions FSEC enema can alleviate DSS-induced acute colitis in mice．

Objective To establish and identify the rabbit model of lumbar disc with severe degeneration．Methods Six New Zealand white rabbits were selected,lumbar X-ray and Pfirrmann grade by MR scan were performed before surgical intervention．Along the space of obliquus externus abdominis and psoas major,the front edge of L2 to L3 was exposed．Then,the nucleus pulposus and part of annulus fibrosus were removed to imitate severe degeneration of lumbar disc．After 6 weeks of rearing,the operated lumbar disc was graded by MR scan,confirming that the lumbar disc met the image of severe degeneration,and then exposed the intervertebral space and injected bone cement．One week later,the anterior lumbar X-ray and the MRI scan for Pfirrmann grading were taken．The animals were sacrificed and dissected to check the bone cement filling in the intervertebral disc．Results The rabbit MR Pfirrmann grade of intervertebral disk was V after 6 weeks of first operation．One week after intervertebral cement injection,the MR Pfirrmann grade was Ⅳ．The surgical segment X-ray was taken one week after the cement injection,which showed that the cement was well filled in the L2-L3 gap and the vertebral space height was close to normal．Animals were sacrificed and dissected,the lumbar intervertebral disc was well filled with cement without shedding or loosening．Conclusions A reliable animal model of lumbar disc with severe degeneration in New Zealand white rabbits can be obtained by injecting cement into the intervertebral space after 6 weeks of removal of the intervertebral disc nucleus pulposus and part of the annulus fibrosus through the obliquus externus abdomins and psoas major intervertebral space．

目的 探讨胃癌误诊为环状胰腺并胰腺炎并十二指肠梗阻的原因和治疗。方法 对本院收治的1例由胃癌误诊为环状胰腺并胰腺炎以及十二指肠梗阻患者的临床情况加以总结,并总结复习和分析相关文献。结果 本例患者虽最终明确诊断为胃癌,但病理提示分化差,合并全身多处骨转移,疾病进展迅速,后续放化疗效果欠佳。早期诊断、早期治疗是影响胃癌患者预后的关键。结论 胃癌骨转移的发病率低,极少进行骨转移评估,易造成误诊。当出现胃十二指肠流出道梗阻时,虽患者合并环状胰腺,仍需警惕胃癌的可能,及早完善全身检查,明确诊断,采取正确的治疗措施。
