Identification of vascular lumen by singular value decomposition filtering on blood flow velocity distribution
ConclusionWe proposed a novel method for identification of the vascular lumen. The proposed method could suppress the effects of wall motion, which was present in the conventional power Doppler image. The lumen region identified by the proposed method well conformed with the anatomical information in the B-mode image of the corresponding section. (Source: Journal of Medical Ultrasonics)

Effects of Clematis chinensis Osbeck mediated by low-intensity pulsed ultrasound on transforming growth factor- β/Smad signaling in rabbit articular chondrocytes
In this study, we aimed to explore whether and how low-intensity pulsed ultrasound (LIPUS) enhanced CCO delivery into chondrocytes and stimulated biological activity in vitro.MethodsChondrocytes were isolated from knee articular cartilage of 2-week-old rabbits and treated with LIPUS plus CCO or recombinant transforming growth factor beta 1 (TGF- β1; 0.5 ng/mL), with or without anti-TGF-β1 antibodies (10 μg/mL), for 3 days. Cell proliferation was assessed by Cell-Counting Kit-8 assays. Immunocytochemistry, western blotting, and quantitative polymerase chain reaction were applied to detect the exp...

Persistent truncus arteriosus with absent semilunar valve in first trimester
AbstractPersistent truncus arteriosus (PTA) is a relatively uncommon congenital heart disease, accounting for approximately 0.7 –1.4% of all congenital cardiac abnormalities worldwide. PTA is usually accompanied by a single semilunar valve, with leaflets ranging from one to six in number. However, absent semilunar valve (ASV) is rarely seen in PTA. Here, we report a case of prenatally diagnosed PTA accompanied by ASV (PTA- ASV) confirmed by postmortem autopsy. (Source: Journal of Medical Ultrasonics)

High-intensity focused ultrasound ablation: a non-surgical approach to treat advanced and complicated liver alveococcosis
AbstractLiver alveococcosis is a life-threatening parasitic disease with progressive growth and wide metastasis to neighboring tissues, lungs, and brain. The radical treatment option is surgery along with a few chemical therapies. However, the frequency of progression and recurrence, as well as postoperative complications and mortality, remains very high. The high-intensity focused ultrasound (HIFU) treatment system, a therapeutic application using ultrasound to deliver heat or agitation into the body, was initially designed to treat cancer. Advanced and complicated forms of liver alveococcosis usually require surgical tre...

Comparison of hypocrellin B-mediated sonodynamic responsiveness between sensitive and multidrug-resistant human gastric cancer cell lines
ConclusionsThese results suggest that HB-SDT could induce apoptosis in SGC7901 and SGC7901/ADR cells via production of ROS. SGC7901/ADR was found to be more sensitive to HB-SDT than SGC7901 cells under the same experimental condition. Meanwhile, a noteworthy difference in cell membrane injury between SGC7901 and SGC7901/ADR cells was detected. The decreased membrane fluidity in SGC7901/ADR cells may be one of the reasons for its increased membrane damage. (Source: Journal of Medical Ultrasonics)

Ultrasound evaluation of fetal critical aortic stenosis using the left atrium area/cardiac area ratio and the Doppler patterns in the pulmonary veins
AbstractIn fetal critical aortic stenosis (AS), a double reverse pattern in the pulmonary veins (PVs) is associated with a poor prognosis. We evaluated the hemodynamic changes using PV Doppler and the left atrium area/cardiac area (LA/CA) ratio in a fetus at 28  weeks of gestation with critical AS complicated with hydrops fetalis, polyhydramnios, and cardiac abnormality. A markedly enlarged LA and severe mitral regurgitation with critical AS were detected, with LA/CA ratio = 0.40 and double reverse pattern with forward/reverse velocity time integral r atio (FRVR) = 1.18 on PV Doppler.

A case of stage IA pancreatic ductal adenocarcinoma accompanied with focal pancreatitis demonstrated by contrast-enhanced ultrasonography
AbstractA patient with slight dilatation of the main pancreatic duct was followed-up with ultrasonography every 6  months as a high-risk case of pancreatic cancer. Twelve years later, a faint hypoechoic area 13 mm in diameter was first detected on the body of the pancreas. Contrast-enhanced ultrasonography revealed a well-demarcated hypoenhanced area 8 mm in diameter and a hyperenhanced area with an unclear margin. The former was suspected to be a small pancreatic cancer lesion, and the latter to be focal pancreatitis accompanying cancer. However, contrast-enhanced dynamic CT did not suggest any tumor, diagn...

Flexor pollicis longus tendon rupture by sandwiched underlying volar locking plate and distal radius
AbstractFlexor pollicis longus (FPL) tendon rupture is a major complication of volar locking plate fixation for distal radius fractures. The tendon rupture is usually caused by friction between the distal edge of the plate and the FPL tendon, and has been well detected recently with ultrasonography. Rarely, the volar locking plate itself entraps the FPL tendon, leading to its rupture. A 63-year-old man was consistently unable to flex his right thumb after previous surgery for a distal radius fracture at another hospital. Ultrasonography demonstrated loss of tendon gliding and unusual patterns of the FPL tendon. The tendon ...

Aortic valve repair for aortic regurgitation and preoperative echocardiographic assessment
AbstractAortic valvuloplasty (AVP) has been performed less frequently than mitral valvuloplasty. The survival benefit of AVP over replacement has been demonstrated. Therefore, standardization of AVP is crucial for its widespread adoption. The hemodynamic advantage of AVP of preserving the native aortic valve may be one reason for the survival benefit. Recent guidelines still recommend AVP in selected cases compared with the less restricted recommendation for mitral valvuloplasty, although recent studies have proposed earlier indication for surgical intervention. Indication for aortic root replacement is also still conserva...
