【摘要】:結(jié)合藥學、生物學、生物醫(yī)學工程、材料學等多種學科,微氣泡超聲造影劑由于具有超聲顯影增強和藥物裝載功能,目前正朝著實現(xiàn)組織靶向分子成像、結(jié)合其他成像模式的多模態(tài)成像以及結(jié)合藥物或基因,集診斷與治療功能為一體的多模式、多功能方向發(fā)展。肺表面活性物質(zhì)存在于肺泡氣液交界面上,是一種主要由磷脂和特異性蛋白質(zhì)組成的脂蛋白復合物,具有降低肺泡表面張力,實現(xiàn)先天性免疫以及防止病原體入侵體內(nèi)等功能。因此,由肺部表面活性物質(zhì)作為膜殼層穩(wěn)定形成的肺表面活性物質(zhì)微氣泡是一種新型的兼具超聲成像和治療功能的藥物輸運系統(tǒng),是該領域的研究熱點之一。系統(tǒng)闡述了微氣泡在醫(yī)學診療領域中的應用,以及近期肺表面活性物質(zhì)微氣泡的研究進展,并對其在治療上的應用和發(fā)展前景進行了討論。
[Abstract]:With the combination of pharmacology, biomedical engineering, materials science and other disciplines, microbubble ultrasound contrast agents are now moving towards the realization of tissue targeted molecular imaging because of their enhanced ultrasound development and drug loading function. Multimodal imaging combined with other imaging modes and drugs or genes is a multimodal and multifunctional development that integrates diagnostic and therapeutic functions. Pulmonary surfactant, a lipoprotein complex composed of phospholipids and specific proteins, exists at the alveolar gas-liquid interface. It has the functions of reducing alveolar surface tension, realizing congenital immunity and preventing pathogens from invading the body. Therefore, the pulmonary surfactant microbubble, which is formed by pulmonary surfactant as a stable membrane layer, is a new drug delivery system with ultrasonic imaging and therapeutic functions, which is one of the research hotspots in this field. The application of microbubbles in the field of medical diagnosis and treatment and the recent progress in the study of pulmonary surfactant microbubbles were systematically reviewed. The application and prospect of microbubbles in treatment were also discussed.
