Circular RNA hsa_circ_0000277 sequesters miR-4766-5p to upregulate LAMA1 and promote esophageal carcinoma progression.

Growing evidence has indicated that circular RNAs (circRNAs) play a pivotal role as functional RNAs in diverse cancers. However, most circRNAs involved in esophageal squamous cell carcinoma (ESCC) remain undefined, and the underlying molecular mechanisms mediated by circRNAs are largely unclear. Here, we screened human circRNA expression profiles in ESCC tissues and found significantly increased expression of hsa_circ_0000277 (termed circPDE3B) in ESCC tissues and cell lines compared to the normal controls.

Sequential interventional therapy for Budd-Chiari syndrome associated with fresh inferior vena cava thrombosis.

Objective: Our study aimed to evaluate the safety and efficacy of sequential interventional therapy for Budd-Chiari syndrome (BCS) caused by obstruction of the inferior vena cava (IVC) with fresh thrombus in the IVC.

Methods: Full medical records were obtained for 20 patients with BCS associated with fresh IVC thrombus who received sequential interventional therapy from 2014 to 2019 at our hospital. All patients underwent small-diameter percutaneous transluminal angioplasty (PTA) balloon catheter predilation combined with sequential catheter-directed thrombolysis and large-diameter PTA balloon dilation.

Perilipin 5 deficiency promotes atherosclerosis progression through accelerating inflammation, apoptosis, and oxidative stress.

Excessive plasma triglyceride (TG) and cholesterol levels promote the progression of several prevalent cardiovascular risk factors, including atherosclerosis, which is a leading death cause. Perilipin 5 (Plin5), an important perilipin protein, is abundant in tissues with very active lipid catabolism and is involved in the regulation of oxidative stress. Although inflammation and oxidative stress play a critical role in atherosclerosis development, the underlying mechanisms are complex and not completely understood.

Budd-Chiari syndrome with upper gastrointestinal hemorrhage: Characteristic and long-term outcomes of endovascular treatment.

Purpose To identify the characteristics and evaluate the long-term outcomes of endovascular treatment of Budd-Chiari syndrome with upper gastrointestinal hemorrhage. Methods Forty-seven consecutive Budd-Chiari syndrome patients with upper gastrointestinal hemorrhage were referred for the treatment with percutaneous transluminal balloon angioplasty, and subsequently underwent follow-up. Data were retrospectively collected and follow-up observations were performed at 1, 2, 2-5, and 5-8 years postoperatively.

Endovascular Treatment of an Unusual Membranous Obstruction of the Inferior Vena Cava in Budd-Chiari Syndrome Complicated by Mural Portal Vein Thrombosis.

We describe the case of a patient with Budd-Chiari syndrome who presented with an unusual membranous obstruction of the inferior vena cava complicated by massive portal vein thrombosis (PVT). The patient underwent percutaneous transluminal balloon angioplasty through the right groin and was prescribed oral warfarin for 6 months. Treatment resulted in the complete disappearance of the PVT.

Value of blood flow velocity on color Doppler ultrasonography for optimization of delay in scanning time on computed tomography venography in patients with Budd-Chiari syndrome and inferior vena cava obstruction.

Purpose: To prospectively determine the value of blood flow velocity in the inferior vena cava (IVC) on color Doppler ultrasonography for the optimization of the delay in scanning time after contrast injection during computed tomography (CT) venography in patients with Budd-Chiari syndrome (BCS) with IVC obstruction.

Methods: We enrolled 122 consecutive BCS patients with IVC obstruction. All patients underwent color Doppler ultrasonography, CT venography, and digital subtraction angiography (DSA) in that order prior to treatment.

Flat detector C-arm CT-guidance system in performing percutaneous transthoracic needle biopsy of small (≤3 cm) pulmonary lesions.

Background: Nowadays, flat detector (FD) equipped angiographic C-arm computed tomography (CACT) systems can be used to acquire CT-like cross-sectional images directly within the interventional suite. The CACT systems offer real time visualization of transthoracic needle biopsy (TNB) procedure and more flexibility in the orientation of the detector system around the patient compared to traditional CT systems.

Purpose: To evaluate the value of a flat detector C-arm CT-guidance system in performing percutaneous transthoracic needle biopsy (PTNB) for small (≤3 cm) pulmonary lesions in clinical practice.

Spontaneous intrahepatic portosystemic shunt in Budd-Chiari syndrome.

Budd-Chiari syndrome (BCS) caused by hepatic venous outflow obstruction may result in portal hypertension and the development of intrahepatic collaterals that bypass the obstruction. Spontaneous intrahepatic portosystemic venous shunt (SIPSVS) is uncommon and may be associated with portal hypertension. SIPSVS is extremely rare in patients with BCS and has not been well documented.

Endovascular treatment of an unusual primary arterioportal fistula complicated by cavernous transformation of the portal vein caused by portal thrombosis.

We describe an elderly woman who presented with an unusual primary arterioportal fistula and cavernous transformation of the portal vein caused by portal thrombosis, which were subsequently managed with endovascular coil embolization and transjugular intrahepatic portosystemic shunt using 2 stents after balloon remodeling. This case shows a rarely seen condition in the elderly and a novel management strategy that should be considered in the management of this complex disease.

Assessment of 64-row computed tomographic angiography for diagnosis and pretreatment planning in pulmonary sequestration.

Purpose: This study was done to evaluate the clinical implications and results of a prospective protocol using 64-row computed tomographic angiography (CTA) for diagnosis and pre-treatment planning in pulmonary sequestration (PS).

Materials And Methods: Forty-five patients with suspected PS were referred for CTA examination. The accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of measures used to detect PS were determined by patient-based and aberrant systemic artery-based evaluations.

Endovascular treatment for extrahepatic portal vein bifurcation stenosis after a Whipple procedure using the kissing stents technique.

A 57-year-old man presented with a rare extrahepatic portal vein bifurcation scar stenosis involving the proximal splenic vein and superior mesenteric vein after a Whipple procedure. He was treated with endovascular coil embolization for the gastroesophageal varices and kissing stents for the portal vein bifurcation stenosis. This case illustrates a rarely seen complication after the Whipple procedure and a novel management strategy that can be considered in the management of this complex disease.
