【摘要】目的探索内镜直视下应用带膜记忆合金支架对晚期食管、贲门恶性狭窄的介入治疗方法。方法2005年1月2009年11月对49例失去手术机会或拒绝手术的晚期食管癌或贲门癌致食管或贲门狭窄患者,行电子胃镜引导下放置镍钛合金支架;对狭窄程度重、胃镜不能通过者,先行Savary探条扩张再放置支架。结果49例均成功置入支架,解除狭窄有效率达100%。结论内镜直视下带膜支架置入操作方法简便、安全,可改善患者的生存质量,延长生存时间。
ObjectiveTo investigate the association between single nucleotide polymorphism (SNP) rs3754219 in the glucose transporters 1 (GLUT1) gene and genetic susceptibility to type 2 diabetes mellitus (T2DM) in Han population in Guangdong Province.MethodsA total of 1 092 T2DM patients (case group) and 1 092 healthy controls (control group) diagnosed or examined between November 2011 and October 2014 form 10 hospitals were enrolled in this study. SNPscanTM SNP classification technology was used to detect the polymorphism of rs3754219 of GLUT1 genetype. Finally, 1 067 T2DM patients and 1 054 healthy controls were included, removing 37 individuals with SNP typing deletion rates >20% and 26 individucals with failed SNP site genotyping. The differences in allele frequency distribution, genotype, and genetic models between the two groups were analyzed.ResultsAfter correction for age and body mass index, there was no statistically significant difference in allele frequency or polymorphism genotype frequency of rs3754219 (P>0.05). There was no statistically significant difference between the two groups under different genetic models (P>0.05).ConclusionGenetic susceptibility to T2DM in Han population in Guangdong Province may be unrelated to the GLUT1 rs3754219 SNP.
