The pathology of the fibrotic proliferative vitreoretinopathy (PVR) membrane represents an excessive wound healing response characterised by cells' proliferation, migration and secretion of extracellular matrix molecules (ECMs). Retinal pigment epithelial (RPE) cells are a major cellular component of the fibrotic membrane. Endothelin-1 (ET-1) has been reported to be involved in the development of PVR in vivo research. However, little is known about the role of ET-1 in RPE cells in vitro. In the present study, we investigated the role of ET-1 in the proliferation, migration and secretion of ECMs (such as type I collagen and fibronectin) in RPE cells in vitro...

AIMS: To present our technique of suprameatal urethrolysis with Martius flap (SMUM) and outcomes of this procedure for refractory female bladder outflow obstruction (BOO). METHODS: A retrospective chart review was performed to identify female patients who underwent SMUM between January 2010 and August 2016 after failed transvaginal urethrolysis (TVU) for BOO due to prior stress urinary incontinence (SUI) surgery. The primary outcome measure was surgical success defined as patient ability to void volitionally without need for catheterization or additional surgery for BOO...

BACKGROUND: Transforming growth factor (TGFβ)-induced epithelial-mesenchymal transition (EMT) and proteotoxic stress are two main contributors of intraocular fibrotic disorders, including proliferative vitreoretinopathy (PVR) and proliferative diabetic retinopathy (PDR). However, how these two factors communicate with each other is not well-characterized. OBJECTIVE: The aim was to investigate the regulatory role of proteotoxic stress on TGFβ signaling in retinal pigment epithelium...

OBJECTIVE: To compare the efficacies of naftopidil and tamsulosin in terms of reducing storage symptoms in patients with BPH. MATERIAL & METHODS: This prospective randomized study was performed at 10 centers. Ninety-four patients that had been taking tamsulosin for more than 8 weeks, but had an OABSS of greater than 3 points were initially enrolled. After a 1 week washout period, patients were divided into two groups. Forty-five patients were treated with tamsulosin 0...

Trastuzumab is the first-line drug to treat breast cancer with high Her2 expression. However, many cancers failed to respond, largely due to their resistance to NK cell-triggered antibody-dependent cellular cytotoxicity (ADCC). Poliovirus receptor (PVR)-like molecules are known to be important for lymphocyte functions. We found that all PVR-like receptors are expressed on human NK cells, and only TIGIT is preferentially expressed on the CD16+ NK cell subset. Disrupting the interactions of PVR-like receptors with their ligands on cancer cells regulates NK cell activity...

Tetralogy of Fallot is the most common form of cyanotic congenital heart disease. As a result of the surgical strategies employed at the time of initial repair, chronic pulmonary regurgitation (PR) is prevalent in this population. Despite sustained research efforts, patient selection and timing of pulmonary valve replacement (PVR) to address PR in young asymptomatic patients with repaired tetralogy of Fallot (rToF) remain a fundamental but as yet unanswered question in the field of congenital heart disease...

PURPOSE: The renin-angiotensin system is involved in the pathogenesis of fibrosis in several organs via induction of transforming growth factor (TGF) beta. In the pathogenesis of proliferative vitreoretinopathy (PVR) TGF-beta plays a pivotal role, promoting transition of retinal pigment epithelial (RPE) cells into myofibroblasts. We studied the influence of angiotensin converting enzyme-inhibition (ACEI) on cytokines and growth factors, related to PVR in aqueous humor. METHODS: We performed a post hoc analysis of a prospectively conducted interventional case series...

Pulmonary hypertension (PH) falls into 5 groups, as defined by the World Health Organization. Swan-Ganz catheters determine precapillary versus postcapillary PH. The hemodynamic values of PH at rest and with vasodilatory challenge categorize the etiology of PH and guide treatment. RV maladaptations to increased pulmonary vascular resistance (PVR) and the chronicity of the right ventricle's (RV) response to increased PH and/or increased PVR can be understood with pressure-volume (PV) loops constructed with use of conductance catheters...

AIMS: To determine the influence of preoperative detrusor underactivity (DU) on serial long-term outcomes of HPS/PVP or HoLEP for LUTS/BPH, and to compare the influence between the two surgeries. METHODS: A total of 382 men, who underwent 120W-HPS/PVP or HoLEP for LUTS/BPH and for whom 36-month follow-up data were available, were classified into four groups: HPS with DU (n = 145), HPS without DU (n = 44), HoLEP with DU (n = 105), and HoLEP without DU (n = 88)...

Pulmonary arterial hypertension (PAH) is a complex disease with a poor prognosis. Selexipag is a selective prostacyclin receptor agonist with vasodilatory, anti-proliferative, anti-inflammatory, and pro-angiogenic properties. However, no clinical data on its therapeutic use in children with PAH are currently available. Here, we report the case of a 12-year-old girl who presented in World Health Organization (WHO) functional class III and right ventricular (RV) failure with recurrent syncope, dizziness, and progressive fatigue for two years...

A growing body of evidence suggests that exercise pulmonary hypertension (ePH) is an early form of pulmonary arterial hypertension (PAH). Identifying the disease at an early, potentially more responsive phase, and initiating treatment may improve functional status and prevent progression to severe forms of PAH. This was a single-center, open-label six-month treatment trial to evaluate the effect of ambrisentan on pulmonary hemodynamics and exercise capacity in ePH utilizing invasive cardiopulmonary exercise testing (iCPET)...

Left ventricle (LV) distension is a complication of venoarterial extracorporeal membrane oxygenation (VA-ECMO) support. The effects of Impella on the pulmonary circulatory physiology were studied in a single-center study of six consecutive patients on VA-ECMO support who had LV unloading with Impella. Right ventricular stroke volume, pulmonary hemodynamics, and partial pressure of end-tidal CO2 (PETCO2 ) were measured on echocardiogram, pulmonary artery catheter, and capnography, respectively. The addition of Impella CP increased total blood flow and reduced pulmonary artery wedge pressure...

The purpose of this study was to investigate the incidence and risk factors of male urinary tract infection (UTI) after urodynamic study (UDS). A total of 854 consecutive male patients, who underwent UDS at Peking Union Medical College Hospital from January 2010 to March 2016, were recruited in this study. Two to four weeks before the examination, urinalysis with bacterial culture was performed. Patients with negative results were selected for UDS. Immediately before the examination, urinalysis was repeated to rule out any preoperative UTI...
