Ultrasound in Obstetrics &Gynecology, Volume 58, Issue 4, Page 582-589, October 2021., 2021 Abstract Objective A trial comparing prenatal with postnatal open spina bifida (OSB) repair established that prenatal surgery was associated with better postnatal outcome. However, in the trial, fetal surgery was carried out through hysterotomy. Minimally invasive approaches are being developed to mitigate the risks of open maternal–fetal surgery.

Research on High Molecular Polymer Ultrasound Contrast Agent for Drug Delivery [PDF]
, 2007 癌症是威胁人类健康的重大疾病之一，恶性肿瘤的治疗在很大程度上仍以化疗为主。肿瘤化疗药物大多数为细胞毒性药物，具有较大的毒副作用。靶向给药系统能将药物定向输送到治疗部位，提高治疗部位的药物浓度，减少药物用量，降低不良反应，提高药物的安全性、有效性和患者的顺应性，是目前抗肿瘤治疗领域研究的重点。最新研究表明，超声空化过程中产生的“空化效应”、“声孔效应”能够实现药物的体内定位释放和提高治疗效果。微泡超声造影剂（UCA）作为一种新型的体内靶向给药载体系统受到广泛关注 ...

Preparation of 10-hydroxycamptothecin loaded PLA microbubbles and evaluation of bioeffect on hepatocellular carcinoma cells induced by ultrasound [PDF]
, 2010 摘要 癌症是威胁人类健康的重大疾病之一，恶性肿瘤的治疗在很大程度上仍以化疗为主。近年来，载药微泡联合超声辐照治疗肿瘤也日益受到重视。 羟基喜树碱（HCPT）是一种广谱的抗肿瘤药物，临床上主要剂型为注射用冻干粉。聚乳酸（PLA）有良好的生物相容性和生物降解性，在生物医学领域有广泛的应用前景。为了增加靶向部位血药浓度，降低给药量，减小毒副作用，本课题探索载羟基喜树碱－聚乳酸微泡的制备及超声辐照下对肿瘤细胞生物效应的影响。 本文的主要研究包括： (1)以聚乳酸为成膜材料 ...
