PURPOSE To investigate whether topical administration of pirfenidone eye drops could be used to prevent postoperative scarring in a rabbit model of experimental glaucoma filtration surgery. METHODS In a randomized, controlled, masked-observer study, 40 rabbits underwent trabeculectomy in the right eyes and randomly received postoperative administration of(More)
Vasoactive intestinal peptide (VIP) is one of the most plentiful neuropeptides in the lung and it has anti-inflammatory effects in the respiratory system. Triggering receptors expressed on myeloid cells-1 (TREM-1) and triggering receptors expressed on myeloid cells-2 (TREM-2) regulate immune responses to lipopolysaccharide (LPS). In the present study, we(More)
PURPOSE Pirfenidone (5-methyl-1-phenyl-2-[1H]-pyridone) is a new, broad-spectrum agent that has an inhibition effect on the proliferation, migration, and collagen contraction of human Tenon's fibroblasts, and thus modulating the wound healing process of glaucoma filtering surgical site. This study investigated the pharmacokinetics of topically administered(More)
Calcitonin gene-related peptide (CGRP) is a 37-amino acid neuropeptide derived from the calcitonin gene. CGRP is widely distributed in the central and peripheral neuronal systems. In the lung, CGRP could modulate dendritic cell function, stimulate proliferation of alveolar epithelial cells and mediate lung injury in mice. In this study, we investigated the(More)
Vasoactive intestinal peptide (VIP) is one of the most important sensory neuropeptides in respiratory system. We previously reported that VIP enhances wound healing and proliferation of human bronchial epithelial cells (HBECs), and these effects are mediated by intracellular signaling molecules such as protein kinase A (PKA), protein kinase C (PKC),(More)
Epoxyeicosatrienoic acids (EETs), the metabolites of arachidonic acid derived from the cytochrome P450 (CYP450) epoxygenases, are mainly metabolized by soluble epoxide hydrolase (sEH) to their corresponding diols. EETs but not their diols, have anti-inflammatory properties and inhibition of sEH might provide protective effects against inflammatory fibrosis.(More)
Triggering receptor expressed on myeloid cells 1 (TREM-1) increases the expression of TGF-β family genes, which are known as profibrogenic cytokines in the pathogenesis of pulmonary fibrosis. In this study, we determined whether TGF-β1 regulated the expression of TREM-1 in a mouse model of pulmonary fibrosis. The expression of TGF-β1 and TREM-1 was(More)
PURPOSE To identify a disease-causing paired box 6 (PAX6) gene mutation in a Chinese family affected by autosomal dominant congenital aniridia. METHODS All participants in the study, including the aniridia family and 100 unrelated senile cataract controls, received a comprehensive ophthalmic examination. Genomic DNA was extracted from their whole blood.(More)
