Epstein-Barr virus-positive iris diffuse large B-cell lymphoma detected by metagenomic next-generation sequencing.

Purpose: Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (DLBCL) is a relatively rare subtype of DLBCL. Herein, we report a case of a patient with EBV-positive iris DLBCL after undergoing penetrating keratoplasty and discuss its possible pathogenesis.

Methods: A 72-year-old male patient presented to our hospital with progressive blurring of vision in the left eye for the past 4 months.

Purpose: To assess potential associations between the prevalence of age-related macular degeneration (AMD) and systemic parameters in a Chinese population.

Design: Cross-sectional study.

Methods: The Tongren Health Care Study included individuals attending regular health care check-up examinations in the Beijing Tongren Hospital from 2017 to 2019.

Effect of supplemental lutein and zeaxanthin on serum, macular pigmentation, and visual performance in patients with early age-related macular degeneration.

Purpose: To compare the 2-year effect of multiple doses of lutein/zeaxanthin on serum, macular pigmentation, and visual performance on patients with early age-related macular degeneration (AMD).

Methods: In this randomized, double-blinded, and placebo-controlled trial, 112 early AMD patients randomly received either 10 mg lutein, 20 mg lutein, a combination of lutein (10 mg) and zeaxanthin (10 mg), or placebo daily for 2 years. Serum concentration of lutein/zeaxanthin, macular pigment optical density (MPOD), visual functions including best-spectacle corrected visual acuity (BCVA), contrast sensitivity (CS), flash recovery time (FRT), and vision-related quality of life (VFQ25) was quantified.

Anatomical outcome of vitreoretinal surgery using temporary keratoprosthesis and replacement of the trephined corneal button for severe open globe injuries: one-year result.

In this case series of 74 patients with coexisting vitreoretinal injury and severe corneal opacification, after temporary keratoprosthesis (TKP) assisted pars plana vitrectomy (PPV), an allograft corneal transplant was not performed at the same time; instead, the patient's trephined corneal button was sutured back. One year after the surgery, if intraocular pressure of the injured eyes was above 8 mmHg, removing silicone oil was attempted, and penetrating keratoplasty could be performed. Finally, 10 eyes (13.

Serum and macular responses to multiple xanthophyll supplements in patients with early age-related macular degeneration.

Objective: This randomized controlled trial examined serum and macular (in vivo measured macular pigment optical density [MPOD]) responses to supplemental lutein and zeaxanthin in Chinese subjects with early age-related macular degeneration.

Methods: One hundred and eight patients with early age-related macular degeneration older than 50 y were randomized to low lutein (LL; 10 mg/d), high lutein (HL; 20 mg/d), lutein plus zeaxanthin (LZ; each 10 mg/d), or placebo during a 48-wk intervention. Serum concentrations were quantified by C(30) high-performance liquid chromatography (at baseline and 4, 12, 24, and 48 wk), and MPOD was measured by analysis of autofluorescence images (at baseline and 24 and 48 wk).

Effect of lutein and zeaxanthin on macular pigment and visual function in patients with early age-related macular degeneration.

Purpose: To determine whether supplementation with lutein and zeaxanthin improves macular pigment and visual function in patients with early age-related macular degeneration (AMD).

Design: Randomized, double-masked, placebo-controlled trial.

Participants: Participants with probable AMD who were 50 to 79 years of age were screened for study eligibility from the local communities.

Improvement of retinal function in early age-related macular degeneration after lutein and zeaxanthin supplementation: a randomized, double-masked, placebo-controlled trial.

Purpose: To examine the effects of lutein and zeaxanthin supplementation on retinal function using multifocal electroretinograms (mfERG) in patients with early age-related macular degeneration (AMD).

Design: Randomized, double-masked, placebo-controlled trial.

Methods: One hundred eight subjects with early AMD were randomly assigned to receive 10 mg/d lutein (n = 27), 20 mg/d lutein (n = 27), 10 mg/d lutein plus 10 mg/d zeaxanthin (n = 27), or placebo (n = 27) for 48 weeks.

Lutein and zeaxanthin intake and the risk of age-related macular degeneration: a systematic review and meta-analysis.

Lutein and zeaxanthin are thought to decrease the incidence of age-related macular degeneration (AMD); however, findings have been inconsistent. We conducted a systematic literature review and meta-analysis to evaluate the relationship between dietary intake of lutein and zeaxanthin and AMD risk. Relevant studies were identified by searching five databases up to April 2010.

Serum inflammatory factors in patients with idiopathic choroidal neovascularization.

Objective: To investigate serum inflammatory factors in patients with idiopathic choroidal vascularization (CNV), including vascular endothelial growth factor (VEGF), tumor necrosis factor alpha (TNFα), Interleukin1-beta (IL1-β), IgG, IgA, IgM, IgE, 50% hemolytic unit of complement (CH50), complement C3, complement C4 and C reactive protein (CRP).

Methods: 21 patients and 20 normal individuals were recruited. They received comprehensive ophthalmic examinations.

Targeted treatment of choroidal neovascularization using integrin-mediated sterically stabilized liposomes loaded with combretastatin A4.

Purpose: The objective of this study was to develop an efficient vasculature-targeted liposomal combretastatin A4 (CA4), by the modification of the sterically stabilized liposomes (SSL) with a ligand of integrins and to explore the possibility of such system for the treatment of choroidal neovascularization (CNV).

Methods: CA4-loaded liposomes were prepared by thin-film dispersion method. The linear arginine-glycine-aspartic acid tripeptide (RGD) with affinity for integrins such as alphavbeta3 expressed on rapidly proliferative vascular endothelial cells was coupled to the distal end of polyethylene glycol (PEG) connected on the surface of SSL.

Baicalein reduces inflammatory process in a rodent model of diabetic retinopathy.

Purpose: This study was designed to elucidate the role of inflammatory process in diabetic retinopathy and to investigate the effect of baicalein treatment on diabetic rat.

Methods: Retinal microglial cells were identified with CD11b antibody, and retinal Müller cells were identified with glial fibrillary acidic protein (GFAP). The gene expression of interleukin (IL)-18, tumor necrosis factor (TNF)-alpha, and IL-1beta was examined by quantitative real-time PCR.

[Effect of temperature on the secondary structure of fish scale collagen].

Pepsin-soluble collagen (PSC) was extracted from fish scale of grass carp and was analyzed by SDS-PAGE, which confirmed that PSC are typical type I collagen and reach electrophoretic purity. Effect of temperature on the secondary structure of collagen was studied by FTIR, Raman and CD. FTIR indicated that the fish scale PSC had typically characteristic absorptions of collagen, and 1659, 1552 and 1238 cm(-1) were assigned to be amide I, II and III respectively.
