简介:【内容摘要】统编教材从一年级起就安排了众多的分类练习,随着年级的升高,分类的要求也随之提升;中年级到高年级,除了继续进行分类积累词语、专项的分类练习以外,还引导学生将分类的方法运用于阅读与习作中。因此,在语文教学中字、词、阅读、写作的分类学习用到思维导图会优化学生的学习。
简介:摘要:目的:甲状腺结节分类诊断过程中采用TI-RADS分类法,观察该种分类方法的应用效果。方法:将我科2018年1月--2020年10月的甲状腺结节297例患者353个结节作为观察对象,并且根据分类方法不同,将患者分成一组和二组,一组使用TI-RADS分类法,二组使用ATA标准分类。结果:(1)本次总共选择353个甲状腺结节作为研究对象,其中良性结节210个,占比59.49%;恶性结节143个,占比40.50%。(2)一组和二组甲状腺结节分类后从NPV、PPV、敏感性、特异性、准确性对照中,一组分别是94.33%、76.20%、88.66%、84.13%、89.23%,二组分别是85.26%、69.68%、77.33%、71.10%、81.01%。(x2=10.021,p=0.000),结果有差异。结论:甲状腺结节诊断过程中采用TI-RADS分类法价值较高,该种方法值得在临床上推广。
简介:AbstractWith the development of human assisted reproductive technology (ART), an objective, accurate, and non-invasive method to assess the quality and viability of oocytes and embryos remains one of the most significant goals. Granulosa cells (GCs) play an essential role in oocyte development. GCs can differentiate into mural GCs (MGCs) and cumulus cells (CCs) under the influence of oocytes. MGCs promote the growth and development of follicles by secreting cytokines and steroid hormones. Simultaneously, CCs can form cumulus-oocyte complexes to communicate with oocytes through gap junctions and promote oocyte growth and maturation. Seeking suitable biomarkers in GCs provides a direction for the non-invasive assessment of oocyte and embryo abilities during ART procedures. To date, only a few studies have investigated potentially effective GC biomarkers during ART processes, such as the apoptosis of GCs, transcriptomic characteristics of GCs, quality and quantity of mitochondria in GCs, and telomere length of such cells. These are potential reference indices for screening high-quality oocytes and embryos. Independent studies on MGCs and CCs can provide more effective results. Although there is scope for optimization and improvement, the results have become increasingly accurate with the constant advances in technology. Due to the heterogeneity of the study population and technical limitations, clinical tests for GCs cannot be performed as part of routine tests, but their prospects are promising. This article reviews the biomarkers that have been studied in MGCs and CCs.
