Article Abstract
Objective: To investigate the effect of Quyu Xiaoban Capsule (QYXB) on the regressive treatment of atherosclerosis (AS) with acoustic densitometry (AD) technique.
Methods: Eighty patients with AS were randomly divided into two groups, trial group was treated with QYXB and conventional medicine, and control group was treated with conventional medicine alone. Normal arterial wall and different types of atherosclerotic plaques were detected with AD technique before treatment and 10 months later.
Results: The corrected averages in intimal echo intensity (AIIc%) were elevated in both groups but without significant difference, AIIc% of fatty plaques were increased in both groups and the value after treatment was significantly higher than that of pre-treatment in the trial group (68.12 +/- 5.54 vs 61.43 +/- 5.37, P < 0.05). The increment rate of AIIc% in trial group was significantly higher than that in control group (10.9 +/- 5.1% vs 2.5 +/- 5.5%, P < 0.05).
Conclusion: QYXB can stabilize the atherosclerotic plaque by increasing its acoustic density. Acoustic densitometry technique can differentiate the different histological plaques and monitor the histological changes of plaques during treatment.

The study described here was aimed at investigating the feasibility of using the ultrasonic through-transmission technique to estimate human musculoskeletal and fat properties. Five hundred eighty-two volunteers were assessed by dual-energy X-ray absorptiometry (DXA) and ultrasonic transmission techniques. Bone mineral density (BMD), muscle and fat mass were measured for both legs and the whole body.

Dual-energy X-ray absorptiometry (DXA) machines based on bone mineral density (BMD) represent the gold standard for osteoporosis diagnosis and assessment of fracture risk, but bone strength and toughness are strongly correlated with bone collagen content (CC). Early detection of osteoporosis combined with BMD and CC will provide improved predictability for avoiding fracture risk. The backscattering resonance (BR) phenomenon is present in both ultrasound (US) and photoacoustic (PA) signal transmissions through bone, and the peak frequencies of BR can be changed with BM and CC.

Noise exposure is the most important external factor causing acquired hearing loss in humans, and it is strongly associated with the production of reactive oxygen species (ROS) in the cochlea. Several studies reported that the administration of various compounds with antioxidant effects can treat oxidative stress-induced hearing loss. However, traditional systemic drug administration to the human inner ear is problematic and has not been successful in a clinical setting.

Background: The aim of this study was to assess the biomechanical characteristics of carotid atherosclerotic plaques using intima-media thickness (IMT) automatic tracking combined with acoustic densitometry (AD) imaging, and to elucidate the relationship between biomechanical characteristics and inflammatory activity of corresponding plaques evaluated by 18F-Fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT).
Methods: Sixty-one patients with isolated carotid atherosclerotic plaques underwent conventional carotid ultrasonography, IMT automatic tracking, and acoustic densitometry (AD) imaging. Following these assessments, patients received an 18F-FDG PET/CT scan within 24 hours.
