Purpose: To investigate the effects of uncorrection and full correction of myopia on myopia progression in Chinese children during a follow-up of two years.Methods: Myopia was defined as cycloplegic s
目的：病理性近视是目前最常见的难治性致盲眼病之一,人Lumican基因(LUM基因)是重要候选基因,建立携带突变位点(cDNA596T＞C)的LUM基因的转基因鼠模型,为深入研究病理性近视的发病机制奠定基础.方法：利用基因重组技术,将人工合成的LUM基因第二外显子596位碱基T替换为C,再克隆到质粒pRPDes3d的多克隆位点,构建pRP.E×3d-EF1A＞LUM/flag＞IRES/hrGFP
Purpose: Lumican gene (LUM) is a candidate gene of myopia in MYP3 locus, and lumican is one of the major extracellular matrix components of the sclera.A mutant lumican (Leu 199 Pro, L199P) transgenic
目的 观察中药对小儿复发性呼吸道乳头状瘤(JORRP)中人乳头状瘤病毒(HPV)含量的影响.方法 将80例JORRP患者分为治疗组40例、对照组40例.对照组采用全麻支撑喉镜下CO2激光手术治疗,术中彻底切除肿瘤组织.治疗组在对照组手术治疗的基础上,根据患儿Derkay评分加服中药基本方Ⅰ或基本方Ⅱ治疗.比较2组治疗前后的HPV-DNA含量.结果 HPV-DNA含量治疗前治疗组与对照组比较差异无统
