Pulmonary hypertension (PH) is fatal disease which closely involves Rho A/ Rho kinsase (ROCK) pathway. Aloperine is a main active alkaloid extracted from Sophora alopecuroides, which is a traditional Chinese herbal medicine that has been used widely. However, the effects of this alkaloid on pulmonary hypertension and its mechanisms remain unclear. Therefore, this study is designed to investigate whether aloperine has protective effects on PH induced by monocrotaline, whether these effects may be related to regulation of RhoA/ROCK pathway in rats...

BACKGROUND: Persistent pulmonary hypertension of the newborn (PPHN) is associated with severe morbidity and mortality. Twin-twin transfusion syndrome (TTTS) is suggested to increase the risk of PPHN. OBJECTIVES: To describe the incidence of PPHN in TTTS twins and to identify risk factors in TTTS twins for the development of severe PPHN. METHODS: Cases with severe PPHN were extracted from our monochorionic twin database (2002-2016). Severe PPHN was defined as severe hypoxaemia requiring mechanical ventilation and inhaled nitric oxide (iNO) treatment, confirmed by strict echocardiographic criteria...

BACKGROUND: Pulmonary arterial hypertension is often associated with connective tissue disease. Although there are some animal models of pulmonary hypertension, an autoimmune disease-based model has not yet been reported. MRL/lpr mice, which have hypergammaglobulinemia, produce various autoimmune antibodies, and develop vasculitis and nephritis spontaneously. However, little is known about pulmonary circulation in these mice. In the present study, we examined the pulmonary arterial pressure in MRL/lpr mice...

Pulmonary artery hypertension (PAH) is characterized by structural changes in pulmonary arteries. Increased numbers of cells expressing α-smooth muscle actin (α-SMA) is a nearly universal finding in the remodeled artery. It has been confirmed endothelial-to-mesenchymal transition (EndoMT) may be a source of those α-SMA-expressing cells. In addition, the EndoMT is reversible. Here, we show that under hypoxia, the expression of bone morphogenetic protein 7 (BMP-7) was decreased both in vivo and in vitro. We also found that under normoxia, BMP-7 deficiency induced spontaneous EndoMT and cell migration...

Pulmonary hypertension (PH) is a life-threatening lung disorder with towering prevalence and risk for future has been gradually rising worldwide. Even, no specific medications are available for pulmonary hypertension; various classes of treatment based upon the origin and magnitude of hypertension are still used for the treatment of PH. Consideration of molecular or signaling modulation is the imperative approach that can offer a new notion for prevalent pharmacotherapeutic agents. Instead of concurrent targets, including endothelin receptor antagonists (ETA/ETB), phosphodiesterase 5 inhibitor (PDF-5), calcium channel blockers, anticoagulants, diuretics and long acting prostacyclin analogue, recent scientific reports revealed the numerous potential alternative therapeutic approaches that can significantly target the pathological signaling alteration associated with PH...

The endothelial-to-mesenchymal transition (EndMT) has been demonstrated to be involved in pulmonary vascular remodeling. It is partly attributed to oxidative and inflammatory stresses in endothelial cells. In current study, we conducted a series of experiments to clarify the effect of salvianolic acid A (SAA), a kind of polyphenol compound, in the process of EndMT in human pulmonary arterial endothelial cells and in vivo therapeutic efficacy on vascular remodeling in monocrotaline (MCT)-induced EndMT. EndMT was induced by TGFβ1 in human pulmonary arterial endothelial cells (HPAECs)...

BACKGROUND: Cancer patients are often thought to have worse surgical outcomes. There is a growing view that risk models do not adequately predict these outcomes. This study aims to compare the use of common risk models for benign versus malignant gastrointestinal disease. MATERIALS AND METHODS: The National Surgical Quality Improvement Program (NSQIP) 2005-2015 participant use files were queried for patients undergoing elective surgery for benign and malignant diseases with a primary procedure code for major colon, pancreas, or stomach resection...

Persistent pulmonary hypertension (PPHN) is a consequence of failed pulmonary vascular transition at birth and leads to pulmonary hypertension with shunting of deoxygenated blood across the ductus arteriosus (DA) and foramen ovale (FO) resulting in severe hypoxemia, and it may eventually lead to life-threatening circulatory failure. PPHN is a serious event affecting both term and preterm infants in the neonatal intensive care unit. It is often associated with diseases such as congenital diaphragmatic hernia, meconium aspiration, sepsis, congenital pneumonia, birth asphyxia and respiratory distress syndrome...

Pulmonary arterial hypertension (PAH) is a rare disease resulting in progressive remodeling of the pulmonary vasculature and eventual right ventricular failure. Despite the development of 13 therapies for PAH since 2000, the use of continuously infused prostanoids retains a special role. Infused medications present unique challenges, and the search for an efficacious oral prostanoid culminated in the FDA approval of oral treprostinil - a first in class oral prostanoid medication approved to treat pulmonary arterial hypertension (PAH)...

Lung diseases remain one of the main causes of morbidity and mortality in neonates. Cell therapy and regenerative medicine have the potential to revolutionize the management of life-threatening and debilitating lung diseases that currently lack effective treatments. Over the past decade, the repair capabilities of stem/progenitor cells has been harnessed to prevent/rescue lung damage in experimental neonatal lung diseases. Mesenchymal stromal cells and amnion epithelial cells exert pleiotropic effects and represent ideal therapeutic cells for bronchopulmonary dysplasia, a multifactorial disease...

PURPOSE: A straightforward, noninvasive method is needed to assess emphysema and pulmonary hypertension (PH) in COPD patients. The desaturation-distance ratio (DDR) is an index derived from the distance traveled and level of desaturation during a six-minute walk test (6MWT); it has previously been shown to be associated with percentage of forced expiratory volume in the first second of expiration (%FEV1.0) and percentage of diffusion capacity of the lung for carbon monoxide (%DLCO). The aim of this study was to examine the associations between DDR and emphysema and PH...

BACKGROUND: Macitentan is beneficial for long-term treatment of pulmonary arterial hypertension. The microvasculopathy of chronic thromboembolic pulmonary hypertension (CTEPH) and pulmonary arterial hypertension are similar. METHODS: The phase 2, double-blind, randomised, placebo-controlled MERIT-1 trial assessed macitentan in 80 patients with CTEPH adjudicated as inoperable. Patients identified as WHO functional class II-IV with a pulmonary vascular resistance (PVR) of at least 400 dyn·s/cm(5) and a walk distance of 150-450 m in 6 min were randomly assigned (1:1), via an interactive voice/web response system, to receive oral macitentan (10 mg once a day) or placebo...

Two main sub-phenotypes have been described in sickle cell disease: one with higher baseline haemoglobin and a higher rate of painful crises and one with lower baseline haemoglobin, increased markers of haemolysis and a higher incidence of pulmonary hypertension, priapism and leg ulcers. We compared the patterns of response to regular automated red cell exchange transfusion over a five-year period of 21 patients with recurrent painful crises from the first group and 3 patients with pulmonary hypertension and 5 with recurrent severe stuttering priapism form the second and found them to be distinctly different...

Chronic thromboembolic pulmonary hypertension (CTEPH) should be suspected in patients presenting persistent dyspnea three months after a pulmonary embolism or in patients presenting with acute pulmonary embolism and suggestive images on the CT-scan. For these patients, a specific diagnostic work-up should be performed. First step consists of the ventilation/perfusion (V/Q) scan which is a good screening test due to its high sensitivity and high negative predictive value. Pulmonary angiography remains the gold standard approach for the confirmation of the diagnosis and pre-surgical evaluation of CTEPH...

Pulmonary hypertension (PH) is a devastating pulmonary vascular disease characterized by aberrant muscularization of the normally non-muscularized distal pulmonary arterioles. The expression of the transcription factor, Twist1, increases in the lungs of pulmonary arterial hypertension patients. However, the mechanisms by which Twist1 controls the pathogenesis of PH remain unclear. It is becoming clear that endothelial-to-mesenchymal transition (EndMT) contributes to various vascular pathologies including PH; Twist1 is known to mediate EndMT...

Pulmonary artery hypertension (PAH) is a rare and fatal disorder with extensive remodeling of pulmonary arteries mediated by hyperproliferation of pulmonary artery smooth muscle cell (PASMC). Aberrant platelet-derived growth factor (PDGF) activity can lead to hyperproliferation of PASMC, however, little is known about the role of long noncoding RNA (lncRNA) in this process. Using RNA sequencing (RNA-seq), we identified 725 lncRNAs in rat PASMC (RPASMC), 95 of which were expressed differentially in response to PDGF-BB treatment...
