目的:比较林格液和乳酸林格液(RL)在超声乳化术中作为冲洗液的差异,并探讨其对角膜内皮细胞的影响。方法:这是一项前瞻性介入性双盲临床研究,包括100例(100眼)年龄在50~65岁之间的年龄相关性白内障患者。随机分为两组(每组各50眼)。组1使用林格液,组2使用乳酸盐林格液冲洗液。结果:组1患者平均年龄57.5±8岁,组2患者平均年龄58.6±9岁。3mo后,组1内皮细胞密度平均下降8.5%,组2平均下降3.6%(P=0.013)。此外,组1中央角膜厚度平均增加6.9%,组2平均增加1.5%(P=0.006)。通过将测厚仪和高光显微镜参数的变化率与灌水量相关联得出两者间无显著相关性。结论:与乳酸盐林格液相比,使用林格液作为冲洗液可减少术后内皮细胞的损失,也可减轻术后水肿。

Predictive Value of miRNA-181a in Pediatric Acute Lymphoblastic Leukemia

Journal of Cancer Therapy 2020年第11期11卷 673-682页

作者： Asmaa El desoky Hosny Badrawy Dina Ismail Abd El Razik Khaled F. Riad Omina N.

Background: Acute lymphoblastic leukemia (ALL), a common pediatric malignant neoplasia, showed high relapse rate after induction therapy. Some miRNAs have been shown to regulate normal hematopoiesis and their disruption could contribute to leukemogenesis: Recently, specific miRNA, including miR-181a, was shown to be involved in the pathogenesis of ALL, serving as a biomarker for diagnosis and relapse of ALL. Aim of the Study: To evaluate miR-181a expression level as a predictive marker for children with acute lymphoblastic leukemia. Patients and Methods: 40 pediatric ALL patients were included in this study. miR-181a expression was assessed at diagnosis before start of treatment. Samples were either peripheral blood or bone marrow aspirate sample. Patients were evaluated clinically and laboratory after the induction therapy.
