Purpose: Circular RNAs (circRNAs) are a novel class of endogenous noncoding RNAs that regulate gene expression through the competitive endogenous RNA (ceRNA) mechanism. CircRNA-associated-ceRNA networks are closely related to oxidative stress-related diseases. Oxidative stress-induced dysfunction of the corneal endothelium (CE) is a major pathological feature in many corneal diseases.

Background: Corneal disease is the second most common cause of blindness in China. Clinically, treatment options for corneal diseases with limbal stem cell deficiency (LSCD) are limited due to a shortage of organ donors and inevitable immune rejection. This study aims to determine the efficacy of reconstructing the ocular surface using autologous cultivated adipose tissue-derived stem cells (ADSCs) and to develop a new clinical treatment for patients with LSCD.

Pathological ocular angiogenesis commonly results in visual impairment or even blindness. Unveiling the mechanisms of pathological angiogenesis is critical to identify the regulators and develop effective targeted therapies. Here, we used corneal neovascularization (CNV) model to investigate the mechanism of pathological ocular angiogenesis.

Objective: To evaluate the ability of two scoring systems (CHADS-VASc score and CHADS-VASc+hyperlipidaemia+smoking [CHADS-VASc-HS score]) to predict in-stent restenosis (ISR) among patients undergoing drug-eluting stent (DES) implantation.

Methods: This retrospective study enrolled patients who underwent coronary angiography to assess coronary artery disease severity secondary to a diagnosis of stable angina or acute coronary syndrome that subsequently underwent DES implantations. Demographic, clinical, angiographic and biochemical parameters were compared between those patients that experienced ISR and those that did not during the study follow-up period.

During the past century, the incidence of myocardial infarction has markedly increased worldwide. Percutaneous coronary intervention with stent implantation is often considered as the first-choice treatment, especially in emergency cases. Current guidelines recommend delayed elective noncardiac surgery for such vulnerable patients.

Aims: Stroke is a major cause of mortality and disability, especially for postmenopausal women. In view of the protective action of estrogen, hormone therapy remains the only effective way to limit this risk. The objective of this study was to investigate the efficiency and underlying mechanisms of estrogen neuroprotection.

Stroke is a leading cause of mortality and disability worldwide. There is growing evidence that metformin (Met) has potent neuroprotective effects; however, its mechanisms remain unclear. We examined the role of the arterial baroreflex and cholinergic-α7 nicotinic acetylcholine receptor (α7nAChR) anti-inflammory pathway in the beneficial effects of Met against stroke.

Background/aims: Amiodarone, a thyroid hormone-like molecule, can induce dyslipidemia and thyroid dysfunction. However, the effects of dronedarone on lipid metabolism and of both dronedarone and amiodarone on thyroid function and lipid metabolism remain unknown.

Methods: Fifty male Sprague-Dawley rats were randomly divided into 5 groups (10 in each group): normal control (NC), amiodarone-treated (AMT), dronedarone-treated (DRT), rats treated with amiodarone combined with polyene phosphatidylcholine (AC), and rats treated with dronedarone combined with polyene phosphatidylcholine (DC).

Cornea senses thermal, mechanical and chemical stimuli via various nociceptors. In the early years, knowledge of the mechanism of corneal nociception was merely restricted to neurophysiology, which classifies nociceptors according to the clusters of nerve fibers which transmit identical stimulation signals. During the past decade, benefiting from the promptly developing molecular biology and technology, classification of the nociceptors has been modified into the level of cell sensors, among which, transient receptor potential (TRP) channel superfamily weighs the most.

Cell sheet technology (CST) is based on the use of poly (N-isopropylacrylamide, PNIPAAm), which can be exhibit reversible hydration and dehydration of its polymer chains in response to temperature changes across the lower critical solution temperature(LCST)of 32°C. By reducing the incubation temperature to 20°C, all cultured cells are harvested as intact sheets along with their deposited extracellular matrix (ECM) due to the conversion of the grafted PIPAAm from hydrophobic to hydrophilic, as ECM remains present on the basal surface of the cell sheets, they can maintain cell viability and function as well as directly transplanted to tissue beds or even layered to create three-dimensional (3D) tissue-like structures without any scaffolds or sutures. The temperature-sensitive surfaces' preparation approaches, density, thickness, membrane additive ingredients and so on, all affect cell adhesion and proliferation.

Objective: To evaluate the clinical values of oral ganciclovir on the treatment of herpes simplex keratitis (HSK).

Methods: A randomized, controlled, single-blind and prospective study was carried out from May in 2008 to June in 2009 at Department of Ophthalmology, Eye Ear Nose and Throat Hospital of Fudan University. 60 patients (60 eyes) with HSK, including stromal keratitis and corneal endotheliitis, were enrolled in the study and were randomly arranged into two groups in average.

Rejection after corneal transplantation is currently the lead of the main reasons for corneal graft failure. Penetrating keratoplasty (PK) is still one of the gold standard surgeries for these patients. In recent years, improving the surgical techniques to reduce the incidence of corneal allograft rejection has been the way to more and more attention to the majority of ophthalmologists.

Corneal neovascularization is one of the tough problems in the cornea diseases, but its pathogenesis is still unclear. Binding of angiopoietins family and its receptor Tie2 set up the signal transducing system of Ang/Tie2, which plays the important role in the angiogenesis and regulation. Recently, the study of the signal transducing system of Ang/Tie2 has archived some progression in the corneal neovascularization.
