A comparative study of GPT-4o and human ophthalmologists in glaucoma diagnosis.

Artificial intelligence (AI), particularly large language models like GPT-4o, holds promise for enhancing diagnostic accuracy in healthcare. This study evaluates the diagnostic performance of GPT-4o compared to human ophthalmologists in glaucoma cases. A prospective, observational study was conducted at a tertiary care ophthalmology center.

Caveolin-1 protects retinal ganglion cells in glaucoma by reducing TLR4 and activating the Akt/PTEN signaling pathway.

Glaucoma is a degenerative disease characterized by retinal ganglion cell (RGC) death and visual impairment caused by elevated intraocular pressure (IOP). Elevated IOP can activate microglia, which participate in ganglion cell injury. Based on the study of caveolin-1 (Cav-1) in glaucoma, we aimed to explore the effect and mechanism of Cav-1 on RGC apoptosis in mice with acute ocular hypertension (AOH).

Long noncoding RNA TMPO-AS1 upregulates BCAT1 expression to promote cell proliferation in nasopharyngeal carcinoma via microRNA let-7c-5p.

Background: Long non-coding RNA (lncRNA) is a group of RNA transcripts that contribute to tumor development by post-transcriptionally regulating cancer-related genes. Nasopharyngeal carcinoma (NPC) is an epithelial tumor that occurs in the nasopharynx and is common in North Africa and Southeast Asia. The study investigated the functions of lncRNA TMPO-AS1 in NPC cell proliferation and apoptosis as well as its related competing endogenous RNA (ceRNA) mechanism.

ADSC-Exos outperform BMSC-Exos in alleviating hydrostatic pressure-induced injury to retinal ganglion cells by upregulating nerve growth factors.

Background: Mesenchymal stem cells (MSCs) have protective effects on the cornea, lacrimal gland, retina, and photoreceptor cell damage, which may be mediated by exosomes (exos) released by MSCs.

Aim: To investigate the ameliorating effect of exos derived from different MSCs on retinal ganglion cell (RGC) injury induced by hydrostatic pressure.

Methods: The RGC injury model was constructed by RGC damage under different hydrostatic pressures (40, 80, 120 mmHg).

Simple and rapid detection of three amatoxins and three phallotoxins in human body fluids by UPLC-MS-MS and its application in 15 poisoning cases.

Amatoxins and phallotoxins are toxic cyclopeptides found in the genus Amanita and are among the predominant causes of foodborne sickness and poisoning-related fatalities in China. This study introduces and validates a simple, rapid and cost-effective ultra-performance liquid chromatography-mass spectrometry method for the simultaneous determination and quantification of α-amanitin, β-amanitin, γ-amanitin, phallisacin, phallacidin and phalloidin in human blood and urine. Quick therapeutic decision-making is supported by a 9 min chromatographic separation performed on a Waters Acquity UPLC HSS T3 column (100 mm × 2.

Unconventional surgery for thoracic esophageal rupture with empyema and mediastinitis: a case report and literature review.

Treatment of esophageal perforation or rupture is complicated and controversial, especially in advanced cases. In fact, it is generally accepted that this disease must be treated individually according to the location, causes and clinical features of rupture or perforation. A very rare case was admitted to our department, who was injured 5 days ago by high-pressure gas of a running air compressor and resulted in a long-term longitudinal rupture of the thoracic esophagus.

PDGFRB upregulation contributes to retinal damages in the rat model of retinal ischemia-reperfusion.

Retinal ischemic disease is a major type of retinal diseases causing vision loss. Identifying the molecular mechanisms mediating the retinal ischemia-reperfusion (RIR) is the key to targeted intervention. In this study, we performed RNA-seq analysis of the retinal tissues of a retinal ischemia-reperfusion model of Sprague-Dawley (SD) rats, followed by differential gene expression analysis, gene ontology (GO) enrichment analysis, and protein-protein interaction (PPI) analysis.

The increased expression of cytokeratin 13 leads to an increase in radiosensitivity of nasopharyngeal carcinoma HNE-3 cells by upregulating ERRFI1.

The main factors contributing to the unfavorable outcome in the clinical treatment of patients with nasopharyngeal carcinoma (NPC) patients are radiation resistance and recurrence. This study aimed to investigate the sensitivity and molecular foundation of cytokeratin 13 (CK13) in the radiotherapy of NPC. To achieve this, a human NPC cell line overexpressing CK13, HNE-3-CK13, was constructed.

[A case of acute exudative polymorphous vitelliform maculopathy].

A 35-year-old male patient presented to the hospital with binocular blurred vision for 2 weeks. The visual acuity of both eyes was 0.8.

[Prevalence and risk factors for pterygium in six rural regions of Yunnan Province].

To investigate the prevalence and risk factors of pterygium in the rural population aged 40 years and above of 12 ethnic groups in 6 regions of Yunnan Province. This was a cross-sectional study. According to the method of multistage stratified sampling, samples of the rural population aged 40 years and above were collected from 12 ethnic groups (Han, Yi, Tibetan, Lisu, Bai, Naxi, Zhuang, Miao, Dai, Jingpo, Hani, and Lahu) in six areas (Diqing, Lijiang, Wenshan, Dehong, and Pu'er) of Yunnan Province from March 2019 to November 2019.

[Therapeutic effect of amniotic membrane-fibrin sealant cement on severe ocular surface alkali burn in rabbits].

Objective To prepare a biologically active amniotic membrane powder and explore its preservation conditions, and to evaluate the efficacy of the amniotic membrane (AM)-fibrin sealant (FS) cement made from the amniotic powder on the rabbit severe ocular surface alkali burn model. Methods Experimental research. Fresh AM was air-dried, cooled with liquid nitrogen, ground into amniotic powder and sterilized by radiation.

Cytokeratin 13 promotes radiotherapy sensitivity of nasopharyngeal carcinoma by downregulating the MEK/ERK pathway.

Background: Radiation therapy is the first treatment choice for nasopharyngeal carcinoma (NPC), while radiation resistance and recurrence have become the primary factors and are associated with poor prognosis in the clinical treatment of NPC patients. The purpose of the present study was to explore the sensitivity and molecular basis of cytokeratin 13 (CK13) that regulates NPC radiotherapy.

Methods: HNE-3 or C666-1 cell line was used for overexpression and knockdown tests.
