Objective: To compare the differences in clinical-related factors between patients with type 2 diabetes (T2DM) and those without diabetic retinopathy (DR) and to explore the risk factors or protective factors affecting DR in T2DM patients.
Methods: We performed a retrospective analysis of 380 patients with type 2 diabetes admitted to Handan Central Hospital from June 2023 to May 2024. Clinical data collected included baseline characteristics, hematological tests, metabolic indicators, and information on diabetic complications and comorbidities.
Purpose: To evaluate the influence of systemic factors on macular vessel density in quantitative Optical Coherence Tomography Angiography (OCTA) by sex.
Study Design: A cross-sectional study.
Methods: A total of 2018 adults were recruited in this study.
Three undescribed isosteroidal alkaloids, przewalskines A-C (1-3), as well as seven known alkaloids (4-10) were obtained from Fritillaria przewalskii bulbs. Their structures were deduced by extensive HRESIMS, 1D NMR, and 2D NMR analyses, and their bioactivities were evaluated involving the anti-inflammatory and inhibitory potencies on AChE, BChE, and Aβ aggregation. Compound 4 revealed the potent effect on inhibiting Aβ aggregation activity with IC value of 33.

Methods: All subjects were randomized into control and PDA group.
The random forest algorithm was used to separate the mass concentrations of six air pollutants (SO, NO, CO, PM, PM, and O) contributed by emissions and meteorological conditions. Their variations for five types of sites including Wuhan's central urban, suburb, industrial, the third ring road traffic, and urban background sites were investigated. The results showed that the values of PM/CO, PM/CO, and NO/CO during the lockdown period decreased by 10.

The undescribed compounds were designated taipainines A-D. Of these, taipainine D presented a unique structure having the D/E trans (H-13α/H-17β) and E/F cis (β-axial lone pair of the N atom/H-22β) ring junctions.

Methods: A population-based cross-sectional eye survey was conducted on Chinese adults residing in Hong Kong. 1891 eyes from 1891 participants who completed 4.
The objective of this study was to evaluate relationship with aggregation, secondary structures and gel properties of pork myofibrillar protein with different sodium chloride (1%, 2% and 3%). When the sodium chloride increased from 1 to 3%, the active sulfhydryl, surface hydrophobicity, hardness and cooking yield of myofibrillar protein were increased significantly ( < 0.05), the particle size, total sulfhydryl and Zeta potential were decreased significantly ( < 0.

Subjects demographic and questionnaires to evaluate the functional status were used to correlate with OSD objectively with clinical examination to assess the meibomian gland dysfunction (MGD), corneal staining, Schirmer's test and tear break-up time (TBUT); and subjectively with ocular surface disease index (OSDI).

In this work, poly(vinylidene fluoride)/poly(methyl methacrylate-co-dimethylamino-2-ethyl methacrylate) (PVDF/P(MMA-co-DMAEMA)) blend membrane was quaternized by p-chloromethyl styrene (p-CMS), and the double bonds were introduced onto the membrane surface, which further participated in the polymerization of zwitterionic monomers on the membrane surface. The results indicated that the resultant membrane exhibited obviously improved hydrophilicity and weak positive charge (isoelectric point, 7.

Methods: Subjects were randomized to receive CXL as in the standard protocol for treating keratoconus or a placebo treatment.

Acute myeloid leukemia(AML)is a myelopoietic stem/progenitor malignant disease. The exact etiology of this leukemia remains unclear, thus it is important to explore the pathogenesis of AML and to discover the new diagnostic markers and therapeutic targets. The long non coding RNA (lnc RNA) is a class of RNA molecules with transcripts over 200 nucleotides in eukaryotic cells which almost don't possess the ability to code proteins, but can regulate the expression of other genes at transcriptional and post-transcriptional levels, thereby participate in occurrence and development of varied tumors.

Study Design: A cross-sectional study.
Methods: Subjective refraction and axial length were measured in all participants.
Objectives: To identify the risk factors for poor eye drop application technique in treatment-naïve subjects and to assess if patient education can benefit these subjects.
Methods: Chinese subjects above 60 years were recruited. Questionnaires, including Barthel index; Lawton's instrumental activities of daily living (ADL); Fatigue, Resistance, Ambulation, Illnesses, and Loss of Weight (FRAIL) scale; and Montreal Cognitive Assessment (MoCA), were used to correlate with eye drop application technique (before and after patient education) using Spearman correlation analysis.
Purpose: To observe the long-term changes in dry eye symptoms and vision-related quality of life in age-related cataract patients after phacoemulsification.
Methods: A total of 101 cataract patients after phacoemulsification combined with IOL implantation (Ph-IOL) in one eye were enrolled. Visual acuity, tear film breakup time (BUT), and Schirmer test 1 (ST1) were measured before and 1, 3, and 6 months after surgery.
The benefits of physical exercise on health and well-being have been studied in a wide range of systemic and ocular diseases, including glaucoma, a progressive optic neuropathy characterized by accelerated apoptosis of retinal ganglion cells (RGCs). Elevated intraocular pressure (IOP) and insufficient ocular perfusion have been postulated to be the two main theories in glaucoma development and progression. The effects of exercise in these two aspects have been demonstrated by numerous researches.

Methamphetamine (METH) abuse is a serious social and health problem worldwide. At present, there are no effective medications to treat METH addiction. Here, we report that aggregated single-walled carbon nanotubes (aSWNTs) significantly inhibited METH self-administration, METH-induced conditioned place preference and METH- or cue-induced relapse to drug-seeking behaviour in mice.

Dependencies of enzyme activities on processing temperature and pH were investigated and non-volatile and volatile breakdown products were characterized. The crude enzyme showed a maximum activity with zeaxanthin, followed in decreasing order by β-carotene, canthaxanthin, astaxanthin, and β-apo-8'-carotenal.
