Paxillin promotes the migration and angiogenesis of HUVECs and affects angiogenesis in the mouse cornea.

Neonatal vascular ophthalmopathy is a refractory ophthalmologic disease, and is a major cause of blindness. Occurrence of neonatal vascular ophthalmopathy may be associated with Paxillin, a cellular adhesion molecule which promotes the migration of endothelial cells and angiogenesis. To explore the role of PXN in corneal angiogenesis, human umbilical vein endothelial cells were divided into five groups: i) Control group; ii) Empty vector-transfected control group; iii) PXN knockdown group (shPXN group); iv) PXN-negative control (NC) group; and v) PXN over-expressed group (overExp group).

The role of radiotherapy in pulmonary large cell neuroendocrine carcinoma: propensity score matching analysis.

The aim of the study was to investigate the survival advantage of radiotherapy (RT) in patients with pulmonary large cell neuroendocrine carcinoma (LCNEC). Patients with pulmonary LCNEC were extracted from the Surveillance, Epidemiology, and End Results (SEER) dataset between January 2004 and December 2013. Propensity score matching (PSM) analysis with 1:1 was used to ensure well-balanced characteristics of all comparison groups.

Inhibition of EZH2 alleviates angiogenesis in a model of corneal neovascularization by blocking FoxO3a-mediated oxidative stress.

Enhancer of zeste homolog 2 (EZH2), a well-known methyltransferase, mediates histone H3 lysine 27 trimethylation (H3K27me3) and plays a vital role in ophthalmological disease. However, its role in corneal neovascularization (CoNV) remains unclear. In vitro and in vivo models were assessed in hypoxia-stimulated angiogenesis and in a mouse model of alkali burn-induced CoNV.

The Application of Artificial Neural Networks and Logistic Regression in the Evaluation of Risk for Dry Eye after Vitrectomy.

Supervised machine-learning (ML) models were employed to predict the occurrence of dry eye disease (DED) after vitrectomy in this study. The clinical data of 217 patients receiving vitrectomy from April 2017 to July 2018 were used as training dataset; the clinical data of 33 patients receiving vitrectomy from August 2018 to September 2018 were collected as validating dataset. The input features for ML training were selected based on the Delphi method and univariate logistic regression (LR).

Anomalous retinal artery associated with branch retinal artery occlusion and neovascular glaucoma: A case report.

Background: Congenital anomalous retinal artery is rare and does not typically affect visual acuity. However, an abnormal artery that passes through and supplies blood to the macular area complicated with branch retinal artery occlusion may negatively impact visual acuity. This study reports an unusual case of anomalous retinal artery combined with retinal artery occlusion.

Orbital neuroblastoma metastasis: A case report and literature review.

Rationale: Neuroblastoma is one of the most common tumors found in children, and mostly arises in the adrenal gland and paravertebral regions. Orbital neuroblastoma metastasis is relatively rare, and is associated with poor prognosis. Since the symptoms and signs of orbital neuroblastoma are not specific, its diagnosis remains challenging.

Torsional and burst mode phacoemulsification for patients with hard nuclear cataract: A randomized control study.

This article aims to evaluate the outcomes of torsional and burst mode phacoemulsification in hard nuclear cataracts.Eighty eyes with grade IV or V nuclear opalescence were treated with phacoemulsification and intraocular lens implantation using conventional mode (Group A, n = 40) or torsional and burst mode phacoemulsification (Group B, n = 40). For good visualization of anterior capsule, trypan blue was injected to the anterior chamber before continuous circular capsulorhexis.

Risk Factors for Dry Eye Syndrome: A Retrospective Case-Control Study.

Purpose: To investigate the independent risk factors of dry eye syndrome (DES) in Chinese.

Methods: A hospital-based age- and sex-matched population was enrolled with a case-control ratio of 1:2, with 789 DES case patients and 1119 healthy family members. Both groups underwent standard ophthalmologic examinations, including slit-lamp evaluation of the anterior segment, measurement of tear film breakup time, Schirmer test, and corneal fluorescein staining.

Paxillin regulates vascular endothelial growth factor A-induced in vitro angiogenesis of human umbilical vein endothelial cells.

The purpose of the present study was to investigate the role of paxillin in the vascular endothelial growth factor A (VEGF‑A)‑induced adhesion, proliferation, migration and capillary formation of endothelial cells (ECs) in vitro. Human umbilical vein ECs (HUVECs) were used to evaluate these four processes in vitro. The HUVECs were either mock‑transfected (control), transfected with scramble small interference RNA (siRNA) or transfected with siRNA specifically targeting paxillin.

Retinal nerve fiber layer thickness changes in Parkinson disease: a meta-analysis.

Background: Parkinson disease (PD) is a neurodegenerative process that leads to a selective loss of dopaminergic neurons, mainly in the basal ganglia of the brain. Numerous studies have analyzed the ability of optical coherence tomography (OCT) to detect retinal nerve fiber layer (RNFL) thickness abnormalities and changes in PD, but the results have not always been consistent. Therefore, we carried out a meta-analysis to evaluate the RNFL thickness measured with OCT in PD.

[Effects of focal adhesional kinase signaling on TNF-α induced gelatinases activity in cornea epithelium].

Objective: To investigate the effect of focal adhesional kinase (FAK) on tumor necrosis factor α (TNF-α)-induced MMP-2 and -9 activities in cornea epithelium.

Methods: Experimental research. The human corneal epithelial cells (HCE) were cultured in vitro.
