摘要The present study aimed to quantitatively diagnose and monitor the therapy response of hepatic ischemia reperfusion injury (IRI) with targeted ultrasound (US) imaging. Targeted microbubbles (MBs) were fabricated, and the binding of ICAM-1 antibodies to MBs was observed. To establish a quantitative method based on targeted US imaging, contrast-enhanced ultrasound (CEUS) was applied on IRI rats. After andrographolide treatment, the IRI rats were subjected to the quantitative targeted US imaging for a therapeutic effect. Effective binding of ICAM-1 antibodies to MBs was observed. According to the quantitative targeted US imaging, the ICAM-1 normalized intensity difference (NID) in IRI rats (38.74 ± 15.08%) was significantly higher than that in the control rats (10.08 ± 2.52%, P = 0.048). Furthermore, different degrees of IRI (mild IRI, moderate to severe IRI) were distinguished by the use of NID (37.14 ± 2.14, 22.34 ± 1.08, P = 0.002). Analysis of mRNA expression demonstrated the accuracy of analyzing the NID using quantitative targeted US imaging (R2 = 0.7434, P < 0.001). Andrographolide treatment resulted in obviously weakened NID of ICAM-1 (17.7 ± 4.8% vs 34.2 ± 6.6%, P < 0.001). The study showed the potential of the quantitative targeted US imaging method for the diagnosis and therapeutic monitoring of IRI.
