: Bladder cancer is one of the most frequent malignancies in the urinary system. Radical cystectomy is inevitable when bladder cancer progresses to a muscle-invasive disease. However, cystectomy still causes a high risk of death and a low quality of life (such as ureter-abdomen ostomy, uroclepsia for ileal-colon neobladder). Therefore, more effective treatments as well as bladder preservation are needed. We developed self-assembled tumor-targeting hyaluronic acid-IR-780 nanoparticles for photothermal ablation in over-expressing CD44 (the receptor for HA) bladder cancer, which show high tumor selectivity, high treatment efficacy, good bioavailability, and excellent biocompatibility...

A 60-year-old woman presented with acute eyelid swelling and a subcutaneous hemorrhage in the right eye. Magnetic resonance imaging showed a spherical tumor of the lacrimal gland. The tumor was removed by the Kroenlein method. We diagnosed as a B-cell lymphoma that is unclassifiable, and intermediate between diffuse large B-cell lymphoma (DLBCL) and Burkitt lymphoma (BL) (intermediate DLBCL/BL) based on its immunohistopathological examination and c-MYC/IgH rearrangement. We administered six cycles of dose-adjusted-EPOCH-R (etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin hydrochloride, and rituximab) therapy, and remission of the lymphoma was obtained...

Pathological neovascularization, a leading cause of blindness, is seen in retinopathy of prematurity, diabetic retinopathy, and age-related macular degeneration. Using a mouse model of hypoxia-driven retinal neovascularization, we find that fibroblast growth factor 21 (FGF21) administration suppresses, and FGF21 deficiency worsens, retinal neovessel growth. The protective effect of FGF21 against neovessel growth was abolished in adiponectin (APN)-deficient mice. FGF21 administration also decreased neovascular lesions in two models of neovascular age-related macular degeneration: very-low-density lipoprotein-receptor-deficient mice with retinal angiomatous proliferation and laser-induced choroidal neovascularization...

Intraocular glial lesions are rare and include retinal gliosis, hamartomas, and astrocytomas and rarely ependymomas. Ependymomas are slow-growing glial tumors preferentially arising in the central nervous system (CNS), occasionally presenting at sites outside the CNS, with only 2 cases of primary retinal ependymoma reported till date. We report herein the third such case of a 20-year-old male who presented with a painful blind eye. The enucleated specimen showed presence of a glial tumor with cells arranged in sheets as well as few true rosettes and pseudo-rosettes and an immunohistochemical profile similar to a classical ependymoma at usual sites in the CNS...

REVIEW
Ke Liu, Chang Zou, Bo Qin
Nuclear hormone receptors (NRs) are one of the most abundant transcription factors in the human cells. They regulate expression of genes via interactions with corresponding ligands, co-activators, and co-repressors. These molecular pathways play important roles in the development, cell differentiation, and physiologic and metabolic processes. Increasingly, targeting nuclear receptors is becoming a promising strategy for new drug development. The aim of this review is to discuss the association between nuclear receptors and eye development, and expand their role in various ocular diseases such as keratitis, cataract, glaucoma, uveitis, retinopathy, and ophthalmic tumors...

PURPOSE: Recent clinical and experimental studies have reported favorable results when using Rho-associated kinase (ROCK) inhibitors for ocular disease, and in cell culture. Disruption of the human, nonpigmented ciliary epithelial cells (HNPCECs) that comprise the blood-aqueous barrier (BAB) induces anterior uveitis; these cells therefore provide a useful cell model of ocular disease. In this study, we examined the effects of ROCK inhibitors in anterior uveitis and in HNPCECs. METHODS: Aqueous flare values and intraocular pressures (IOPs) were determined in patients with anterior uveitis, 2 weeks after administration of ripasudil hydrochloride hydrate, a commercial ROCK inhibitor used to treat glaucoma or ocular hypertension...

RATIONALE: A cholesterol granuloma (CG) is usually found in the middle ear, papilla, orbits, petrous apex, and choroid plexus, but is highly uncommon in the skull. In spite of benign clinicopathological lesions, bone erosion can be seen occasionally in the patient with CG. The optimal treatment strategy is radical surgery, but complete excision is usually impossible due to anatomical restrictions and a risk of injury to the key structures located nearby. Here, we report a patient with CGs in the suprasellar and sellar regions who was successfully treated with Java brucea and Chinese herbal medicine...
