Gills are the main respiratory organs of fish and bear important physiological and immunological functions, but the functional heterogeneity of interlamellar cell mass (ILCM) at the single-cell level has rarely been reported. Here, we identified 19 cell types from the gills of crucian carp (Carassius auratus) by single-cell RNA sequencing (scRNA-seq) in combination with histological analysis. We annotated ILCM and analyzed its functional heterogeneity at the single-cell level for the first time.

The injury led to a corneal flap inversion and melting, exacerbated by a delay in seeking treatment due to the pandemic. When she finally presented for medical attention, her vision was severely compromised, with dense epithelial ingrowth obstructing the visual axis or blocking the pupillary entrance.

Their anticancer activities on Hccc-9810, HepG2, MDA-MB-231, Hela, MG-63 and H460 cells are assayed to elucidate their structure-activity relationships. These results showed that the falcarindiol analogue (3R,8S)-2 i with the terminal double bond has the most potent anti-proliferation effect on Hccc-9810 cells with IC value of 0.

Aim: To investigate the mechanism and effect of trabecular tissue repair for corneal defect, and to provide a theoretical basis for its clinical application.
Methods: Trabeculectomy was performed on 40 (80 eyes) of 70 New Zealand white rabbits. Take trabecular tissue for backup.
There are a lot of bacteria in the environment, and Gram-positive bacteria are the most common ones. Some Gram-positive bacteria are very harmful to the human body, so it is significant to predict Gram-positive bacterial protein subcellular location. And identification of Gram-positive bacterial protein subcellular location is important for developing effective drugs.

Purpose: To investigate the gross manifestation and tissue destruction at different inflammatory periods of ligature-induced peri-implantitis in mice model, and to evaluate the changes of interleukins level in the gingival crevicular fluid of implants at different stages.
Methods: Forty 4-week-old male C57BL/6N mice (18-22 g) were used and the maxillary right first molars were extracted, custom-made pure titanium machined screw type implants (1 mm×1.5 mm) were placed immediately, one implant per animal.
Purpose: The mechanisms of naso-ocular interaction in allergic rhinoconjunctivitis are not well understood. Neurogenic inflammation affects both eyes and nose via the same neurogenic factors. The purpose of this study was to investigate the effects of neurogenic inflammation on conjunctival inflammation following nasal allergen provocation.

Methods: Different feeder layers were cultured in Dulbecco's modified Eagle's medium (DMEM)/F12 and were treated with mitomycin C. Rabbits limbal stem cells (LSCs) were co-cultured on hUCMSCs, hUVECs, hDPSCs, hPDLSCs and NIH-3T3, and then comparative analysis were made between each group to see their respective colony-forming efficiency (CFE) assay and immunofluorescence (IPO13,CK3/12).
Aim: To demonstrate the changes in ultrastructure and histopathology of the cornea in acute corneal alkaline burns after femtosecond laser-assisted deep lamellar keratoplasty.
Methods: The New Zealand white rabbits treated with alkaline corneal burn were randomized into two groups, Group A (16 eyes) with femtosecond laser-assisted deep lamellar keratoplasty 24h after burn and Group B (16 eyes) without keratoplasty as controls. All eyes were evaluated with transmission electron microscopy (TEM) at 1, 2, 3, and 4wk follow-up, then all corneas were tested by hematoxylin and eosin staining histology.
Objectives: To quantitatively analyze the vibratory characteristics of vocal folds before and after conservative treatments to evaluate the outcomes of conservative treatments for vocal fold leukoplakia using videostrobokymography (VSK).
Study Design: This is a prospective study.
Methods: Twenty patients and 20 controls were enrolled into the study.
Objectives: To study the protective effect of total glycosides of Ranunculus japonicus (TGRJ) on myocardial ischemic-reperfusion injury in isolated rat hearts.

Aim: To investigate the effect of intravitreal injection administered sorafenib, a multikinase inhibitor, in a rat model of oxygen-induced retinopathy (OIR).
Methods: Seven-day-old Sprague-Dawley rats (n=144) were randomly assigned to six groups. Group A received normal partial oxygen pressure and groups B, C, D, E and F were exposed to hyperoxia (75±2)% from postnatal 7d (P7) to P12 to induce retinopathy of prematurity.
Purpose: Five patients presented to our institution with deep intraorbital foreign bodies adjacent to the optic nerve. We removed all foreign bodies by lateral orbitotomy to evaluate the treatment and the benefits of their extraction.
Methods: The clinical outcomes of the five patients were retrospectively analyzed.
