目的:探讨细胞凋亡在透镜诱导豚鼠近视眼后极部巩膜组织中的表达及其在近视形成中的作用。方法:选健康4周龄豚鼠45只,随机分成3组,1组(右眼配戴-20D)、2组(右眼配戴-10D)3组(不作任何干预)。实验前后用睫状肌麻痹下验光、A超动态观察豚... 目的:探讨细胞凋亡在透镜诱导豚鼠近视眼后极部巩膜组织中的表达及其在近视形成中的作用。方法:选健康4周龄豚鼠45只,随机分成3组,1组(右眼配戴-20D)、2组(右眼配戴-10D)3组(不作任何干预)。实验前后用睫状肌麻痹下验光、A超动态观察豚鼠眼屈光度和眼轴长度,并取后极部巩膜组织,用电镜、终末脱氧核糖核苷酸转移酶介导原位缺口末端标记法(TUNEL)及流式细胞术检测巩膜的凋亡细胞。结果:实验后诱导眼形成近视,且伴有眼轴延长。并在诱导眼巩膜细胞中检测到凋亡细胞,凋亡细胞指数(AI)和凋亡率显著高于对照组(P<0.05),细胞增生指数(PI)显著低于对照组(P<0.05)。结论:在透镜诱导豚鼠实验性近视眼后极部巩膜组织中不仅有细胞增殖的降低,而且还存在细胞凋亡的表达增多。 展开更多

AIM:To investigate the correlation between lumican(LUM)gene and high myopia in a Southern Chinese population.METHODS:The study comprised of 95 high myopia patients with a spherical equivalent≤-6.5 diopters(D).The control group recruited 95 individuals with a spherical equivalent ranging from-0.5 D to+0.5 D.Direct sequencing was used to detect the single nucleotide polymorphisms(SNPs)of LUM gene in coding region.Genotype distributions were tested for Hardy-Weinberg disequilibrium.Genotypic and allelic frequencies were analyzed through Chi-square test or Fisher’s exact test.RESULTS:We identified 3 SNPs of the LUM gene:LUM c.32(rs577456426),LUM c.507(rs17853500)and LUM c.849(rs181915277).Among the three SNPs,the genotype and allele frequencies of rs17853500 showed a significant difference between patients and control subjects(P〈0.05).However,there were no significant differences in rs181915277and rs577456426 between the two groups(P〉0.05).CONCLUSION:LUM c.507 polymorphism may be a risk factor for the pathogenesis of high myopia in the Southern Chinese population. 展开更多
