PURPOSE To evaluate neovascularization within carotid atherosclerotic plaques with contrast-enhanced sonography. METHODS We used contrast-enhanced sonography to examine 63 patients with carotid atherosclerotic plaques. The features of neovascularization within the plaques were analyzed and correlated with plaque size and echogenicity. RESULTS There were(More)
The objective of this study was to investigate the factors for enhancing the susceptibility of cancer cells to chemotherapeutic drug by ultrasound microbubbles. Ultrasound (US) combined with phospholipid-based microbubbles (MB) was used to enhance the susceptibility of colon cancer cell line SWD-620 to anticancer drugs Topotecan hydrochloride (TOP).(More)
Diabetic cardiomyopathy (DCM) is the leading cause of morbidity and mortality among the diabetic patients and currently there is no effective means to reverse its pathological progress. Basic fibroblast growth factor (bFGF) has shown promise as a molecular therapy for DCM, but its delivery is inefficient and non-specific. In the present study, a therapy(More)
Despite progress in the design of advanced surgical techniques, stenosis recurs in a large percentage of vascular anastomosis. In this study, a novel heparin-poloxamer (HP) hydrogel was designed and its effects for improving the quality and safety of vascular anastomosis were studied. HP copolymer was synthesized and its structure was confirmed by Fourier(More)
Ultrasound (US)-mediated cavitation of microbubbles has evolved into a new tool for organ-specific gene and drug delivery. This paper was to investigate the feasibility of acidic fibroblast growth factor (aFGF) intravenous delivery to the ischemic myocardium of rats by ultrasonic microbubbles modified with heparin. Heparin modified microbubbles (HMB) were(More)
An in vivo study on enhancing antitumor effect of intravenous epirubicin hydrochloride (EPI) by acoustic cavitation in situ combined with phospholipid-based microbubbles (PMB) was reported. Five-week-old male nude mice were used, and HCT-116 cells were s.c. (subcutaneous injection) inoculated in axilla of these mice. Five groups were designed and five(More)
Although many agents have therapeutic potentials for central nervous system (CNS) diseases, few of these agents have been clinically used because of the brain barriers. As the protective barrier of the CNS, the blood-brain barrier and the blood-cerebrospinal fluid barrier maintain the brain microenvironment, neuronal activity, and proper functioning of the(More)
In order to facilitate the intracellular delivery of therapeutic agents, a new type of liposomes-propylene glycol liposomes (PGL) were prepared, and their cell translocation capability in vitro was examined. PGL was composed of hydrogenated egg yolk lecithin, cholesterol, Tween 80 and propylene glycol. With curcumin as a model drug, characterization of(More)
Acidic fibroblast growth factor (aFGF) has shown the great potential to prevent the structural and functional injuries caused by diabetic cardiomyopathy (DCM). The present study sought to investigate the preclinical performance and mechanism of the combination therapy of aFGF-nanoparticles (aFGF-NP) and ultrasound-targeted microbubble destruction (UTMD)(More)
Basic fibroblast growth factor (bFGF)-loaded liposome (bFGF-lip) combined with ultrasound-targeted microbubble destruction (UTMD) technique was investigated to prevent diabetic cardiomyopathy (DCM). Cardiac function and myocardial ultrastructure were assessed. Terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick-end labeling (TUNEL) staining,(More)
