组织特异性胞嘧啶脱氨酶和5-氟胞嘧啶热化疗对裸鼠结肠癌肝脏转移的影响

Objective To investigate the effects of tissue specific cytosine deaminase/5-fluorocytosine (CD/5-FC) thermotherapy on hepatic metastasis of colonic carcinoma in nude mice. Methods Forty-five nude mice were randomly divided into control group, 5-FC group and 5-FC thermotherapy group according to the random number table (15 mice in each group). Mice models of hepatic metastasis of colonic carcinoma were established by portal vein injection of LoVo/CEACD cells. The hepatic metastasis rate and number of metastatic nodules of the 3 groups were compared by ehi-square test and one-way ANOVA. The pathological changes in tumor tissues and apoptotic index of tumor cells were observed. The expression of the CD gene in tumor tissues was detected by fluorescent quantitative RT-PCR and Western blot. Results The number of metastatic nodules and liver metas-tasis rate were 4.6±1.3 and 100.0% in control group, 2.2±1.0 and 60.0% in 5-FC group, 0.5±0.8 and 13.3% in 5-FC thermotherapy group, with statistical difference among the 3 groups (F=25.898, χ2=5.208, 19.548, 5.168, P<0.05). The mean apoptotic indexes of tumor cells of the 3 groups were 4.6%, 9.9% and 17.4%, respectively. Vacuolar degeneration, cell necrosis, cytolysis and apoptotic bodies were mostly observed in the 5-FC thermotherapy group. The expression of CD gene in tumor tissue was detected in all the groups. Conclusion Tissue specific CD/5-FC thermotherapy has inhibitory effects on the hepatic metastasis of LoVo cells transfected with CD gene.

长链非编码RNA在胰腺癌中的作用及意义

胰腺癌作为一个侵袭性强、预后不佳的恶性肿瘤之一,在我国的发病率和病死率逐渐上升.尽管手术技术和辅助药物治疗都在不断改进,但胰腺癌患者的生存期依旧没有得到明显的提高.长链非编码RNA(LncRNA)是一类转录长度大于200个核苷的RNA分子,最近的研究表明,LncRNA与胰腺癌细胞的凋亡、转移及耐药等密切相关,对胰腺癌的诊断、治疗及预后的判断具有重要意义,本文将对LncRNA在胰腺癌中的作用机制及意义进行综述.
