Femtosecond laser versus manual clear corneal incision in implantable collamer lens surgery.

This study aims to compare the efficacy and safety of femtosecond laser-assisted implantable collamer lens (ICL) implantation with traditional manual ICL techniques. A retrospective analysis was conducted on patients who underwent ICL implantation at Beijing New Vision Eye Hospital in 2023. Patients (aged 18-45) were matched for gender and refractive error, with forty-two eyes in each group.

Ciliary muscles contraction leads to axial length extension--The possible initiating factor for myopia.

Purpose: This study aimed to investigate the underlying factors driving the onset of myopia, specifically the role of the ciliary muscle's contraction in the elongation of the axial length of the eye.

Methods: The retrospective study was conducted utilizing data from three ophthalmic centers in Shanghai and Beijing. Both Chinese and Caucasian children were involved.

Effect of PCI on ophthalmic artery hemodynamics in patients with acute coronary syndrome.

Purpose: We aimed to explore the effects of percutaneous coronary intervention (PCI) on the ophthalmic artery (OA) hemodynamics in patients with acute coronary syndrome (ACS).

Methods: A total of 73 participants (Group0: healthy controls, Group1: Patients with ACS underwent PCI < 3 months, Group2: Patients with ACS underwent PCI ≥ 3 months) were enrolled. Computed tomographic angiography images were used to construct three-dimensional models of participants' OAs.

An anoikis-related lncRNA signature is a useful tool for predicting the prognosis of patients with lung adenocarcinoma.

Background: Anoikis-related long non-coding RNAs (ARLs) play a critical role in tumor metastasis and progression, suggesting that they may serve as risk markers for cancer. This study aimed to investigate the prognostic value of ARLs in patients with lung adenocarcinoma (LUAD).

Methods: Clinical data, RNA sequencing (RNA-seq) data, and mutation data from the LUAD project were obtained from The Cancer Genome Atlas (TCGA) database.

[Mechanism of Marsdenia tenacissima against ovarian cancer based on network pharmacology and experimental verification].

The present study aimed to explore the main active components and underlying mechanisms of Marsdenia tenacissima in the treatment of ovarian cancer(OC) through network pharmacology, molecular docking, and in vitro cell experiments. The active components of M. tenacissima were obtained from the literature search, and their potential targets were obtained from SwissTargetPrediction.

Impact of total cerebral small vessel disease score on ophthalmic artery morphologies and hemodynamics.

Background: Cerebral small vessel disease (CSVD) is a systemic disease, affecting not only the brain, but also eyes and other organs. The total CSVD score is a tool for comprehensive evaluation of brain lesions in patients with CSVD. The ophthalmic artery (OA) is a direct response to ocular blood flow.

Macular evaluation of the retinal and choroidal vasculature changes in anterior ischemic optic neuropathy-a case control study.

Background: This study aimes to characterize the fundus structural changes in patients with nonarteritic anterior ischemic optic neuropathy (NAION) and the correlation between macular vessel density, retinal nerve fibre layer (RNFL) parameters and visual field sensitivity (VFS) in NAION patients.

Methods: A retrospective case control study was performed using 37 eyes with NAION, 30 uninvolved contralateral eyes, and 27 eyes of healthy age-matched subjects. Data on the retinas and choroidal vessel densities and VFS were compared among the three groups.

Efficacy of Osthole in Management of Hypoperfused Retina.

Purpose: To determine the effect of osthole on the retina in a chronic cerebral hypoperfusion (CCH) rat model and to investigate its therapeutic activity.

Methods: Seventy-two rats were randomly allocated into 6 groups. CCH was induced by permanent bilateral common carotid artery occlusion (BCCAO) in five groups.

[Determination of volatile hydrocarbon in atmosphere by two-dimensional capillary column gas chromatography].

Fifty-seven volatile hydrocarbons (VHCs) (C3-C10) in the atmosphere have been determined by two-dimensional capillary column gas chromatography. The samples were preconcentrated using adsorption/two stages of thermal desorption. The samples were analysed by dual columns (PLOT, 50 m x 0.
