Heating-driven self-assembled glycyrrhizin nanomicelles loading bisdemethoxycurcumin: Preparation, characterization, and efficacy evaluation on experimental dry eye.

In this study, a simple but novel preparation method was developed by heating a mixture of dipotassium glycyrrhizinate (DG) and bisdemethoxycurcumin (BDMC) in aqueous solution, and a DG self-assembled nanomicelles-loading BDMC (named B@DNM) ophthalmic solution was successfully fabricated with this heating-driven process. AutoDock simulation analysis revealed that Pi-Alkyl hydrophobic interactions between BDMC and DG played important role in this self-assembled B@DNM. The optimized B@DNM, with a DG:BDMC mass ratio of 40:1 and heating time of 6 h, had a high encapsulation efficacy of 96.

Abnormal dynamic features of spontaneous brain activity and their concordance in neuromyelitis optica spectrum disorder related optic neuritis: A resting-state fMRI study.

Objective: Characterizing the neuropathological features of neuromyelitis optica spectrum disorder-related optic neuritis (NMOSD-ON) is crucial for understanding its mechanisms. Given the important role of dynamic features in the brain's functional architecture, we aim to investigate the dynamic features of spontaneous brain activity and their concordance using resting-state functional magnetic resonance imaging (rs-fMRI) in NMOSD-ON.

Methods: Fourteen NMOSD-ON patients and 21 healthy controls (HCs) underwent rs-fMRI and ophthalmological examinations.

Speech intelligibility prediction based on a physiological model of the human ear and a hierarchical spiking neural network.

A speech intelligibility (SI) prediction model is proposed that includes an auditory preprocessing component based on the physiological anatomy and activity of the human ear, a hierarchical spiking neural network, and a decision back-end processing based on correlation analysis. The auditory preprocessing component effectively captures advanced physiological details of the auditory system, such as retrograde traveling waves, longitudinal coupling, and cochlear nonlinearity. The ability of the model to predict data from normal-hearing listeners under various additive noise conditions was considered.

Inhibitory effects of flavonoids on organic cation transporter 1: Implications for food/herb-drug interactions and hepatoprotective effects.

Organic cation transporter 1 (OCT1, gene symbol: SLC22A1) is mainly responsible for the hepatic uptake of various cationic drugs, closely associated with drug-induced liver injury (DILI). Screening and identifying potent OCT1 inhibitors with little toxicity in natural products is of great value in alleviating OCT1-mediated liver injury. Flavonoids, a group of polyphenols commonly found in foodstuffs and herbal products, have been reported to cause transporter-mediated food/herb-drug interactions (FDIs).

The relationship between Geriatric Nutritional Risk Index (GNRI) and in-hospital mortality in critically ill patients with Acute Kidney Injury (AKI).

Background: The role of the geriatric nutritional risk index (GNRI) as a prognostic factor in intensive care unit (ICU) patients with acute kidney injury (AKI) remains uncertain.

Objectives: The aim of this study was to investigate the impact of the GNRI on mortality outcomes in critically ill patients with AKI.

Methods: For this retrospective study, we included 12,058 patients who were diagnosed with AKI based on ICD-9 codes from the eICU Collaborative Research Database.

Study of corneal and retinal thicknesses at five years after FS-LASIK and SMILE for myopia.

Background: This study aimed to observe corneal and retinal thicknesses at 5 years after femtosecond laser-assisted in situ keratomileusis (FS-LASIK) and small incision lenticule extraction (SMILE) for myopia, investigate the effect of epithelial remodeling on refractive status and visual quality, and compare retinal thicknesses among fundus tessellation grades.

Methods: Patients who received FS-LASIK or SMILE 5 years before were enrolled in this cross-sectional study. After 1:1 propensity score matching, each surgical group obtained 177 patients (177 eyes).

Corneal biomechanical properties and potential influencing factors in varying degrees of myopia.

To compare the corneal biomechanical parameters measured by Corvis ST in subjects with varying degrees of myopia. And the factors that may affect corneal biomechanical properties were also investigated. Participants in this prospective cross-sectional study were classified into three groups according to spherical equivalent (SE) and axial length (AL): Non-myopia (NM, SE > - 0.

[Genomic profiles and immune microenvironment of olfactory neuroblastoma].

To investigate the genomic profiles and immune microenvironment of olfactory neuroblastoma (ONB). Nineteen ONB cases diagnosed in the Beijing Tongren Hospital from May 2018 to October 2022 were divided into low-grade and high-grade groups according to the Hyams grading system, including 7 low-grade and 12 high-grade ONB. Whole exome sequencing and multiplex immunofluorescence analyses were performed on tissue samples of these ONB.

Lens Power and Associated Factors in Nonhuman Primate Subjects: A Cross-sectional Study.

Purpose: We aimed to examine the normative profile of crystalline lens power (LP) and its associations with ocular biometric parameters including age, axial length (AL), spherical equivalent refraction (SE), corneal radius (CR), lens thickness, anterior chamber depth, and AL/CR ratio among a cynomolgus monkey colony.

Methods: This population-based cross-sectional Non-human Primate Eye Study recruited middle-aged subjects in South China. All included macaques underwent a detailed ophthalmic examination.

Multi-dimensional epidemiology and informatics data on COVID-19 wave at the end of zero COVID policy in China.

Background: China exited strict Zero-COVID policy with a surge in Omicron variant infections in December 2022. Given China's pandemic policy and population immunity, employing Baidu Index (BDI) to analyze the evolving disease landscape and estimate the nationwide pneumonia hospitalizations in the post Zero COVID period, validated by hospital data, holds informative potential for future outbreaks.

Methods: Retrospective observational analyses were conducted at the conclusion of the Zero-COVID policy, integrating internet search data alongside offline records.

Anti-IL-4Rα monoclonal antibody (CM310) in patients with chronic rhinosinusitis with nasal polyps (CROWNS-2): Rationale and design of a multicenter, randomized, double-blind, placebo-controlled, parallel-group study.

Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a heterogeneous disease that affects a large proportion of the global population. The treatment of CRSwNP, especially eosinophilic CRSwNP (ECRSwNP), has always been of great obstacle. Our previous phase 2 trial showed that CM310, a monoclonal antibody that targets interleukin-4 receptor alpha, was both safe and effective in reducing the size of nasal polyps, improving symptom scores, and increasing the quality of life for those with severe ECRSwNP.

Expert consensus on the diagnosis and therapy of endo-periodontal lesions.

Endo-periodontal lesions (EPLs) involve both the periodontium and pulp tissue and have complicated etiologies and pathogenic mechanisms, including unique anatomical and microbiological characteristics and multiple contributing factors. This etiological complexity leads to difficulties in determining patient prognosis, posing great challenges in clinical practice. Furthermore, EPL-affected teeth require multidisciplinary therapy, including periodontal therapy, endodontic therapy and others, but there is still much debate about the appropriate timing of periodontal therapy and root canal therapy.

Effect of intranasal insulin on perioperative cognitive function in older adults: a randomized, placebo-controlled, double-blind clinical trial.

Background: Postoperative cognitive impairment are common neural complications in older surgical patients and exacerbate the burden of medical care on families and society.

Methods: A total of 140 older patients who were scheduled for elective orthopaedic surgery or pancreatic surgery with general anaesthesia were randomly assigned to Group S or Group I with a 1:1 allocation. Patients in Group S and Group I received intranasal administration of 400 μL of normal saline or 40 IU/400 μL of insulin, respectively, once daily from 5 minutes before anaesthesia induction until 3 days postoperatively.

Spatiotemporal Neural Network for Sublexical Information Processing: An Intracranial SEEG Study.
