Diabetic cataract, a prevalent ocular complication of diabetes mellitus, arises from a complex interplay of pathological mechanisms, with oxidative stress and glycation stress playing central roles. Autophagy, a critical cellular self-protection mechanism, sustains intracellular homeostasis by selectively degrading damaged organelles and misfolded proteins, thereby counteracting the detrimental effects of oxidative and glycation stress under hyperglycemic conditions. Emerging evidence indicates a synergistic interaction between glycation stress and oxidative stress, which may exacerbate autophagic dysfunction and accelerate the onset and progression of diabetic cataract. However, the precise molecular mechanisms underlying this relationship remain incompletely understood. This review systematically examines the regulatory role of autophagy inthe pathogenesis of diabetic cataract, with a particular focus on how autophagic impairment influences disease progression under the combined effects of glycation and oxidative stress. By elucidating these mechanisms, the paper aims to provide novel insights into molecular diagnostic approaches and targeted therapeutic strategies for diabetic cataract.

Objective To prepare Zishen pills as gel plaster according to the prescription,and investigate its transdermal absorption characteristics in vitro.Methods Based on preliminary experiments,the matrix prescription of the gel plaster was optimized by single-factor tests and the Box-Behnken design.Evaluation indicators included initial viscosity,viscosity retention and sensory scores.The modified Franz diffusion cell was used to investigate the effect of penetration enhancers on the transdermal characteristics of gel plaster in vitro,with the permeability of neomangiferin,phellodendrine hydrochloride,mangiferin and berberine hydrochloride as evaluation indicators.Results The prescription dosage of the preferred matrix for the Zishen gel plaster was sodium polyacrylate NP700 2.55 g,glycerin 11.04 g,polyvinylpyrrolidone K90 1.13 g,tartaric acid 0.1 g,glycyrrhizin 0.1 g,kaolin 0.3 g,and distilled water 15 g.Among different types and concentrations of permeation enhancers,5%aminoketone showed the best permeation performance.The permeation rates for neomangiferin,phellodendrine hydrochloride,mangiferin,and berberine hydrochloride were 1.5338,1.7809,2.3247 and 20.0899 μg·(cm2)-1·h-1,and the penetration rates were 2.4319,1.9408,1.9604 and 1.4701,respectively.The percutaneous absorption curve of the drug conformed to the zero-order kinetic equation.Conclusion The preparation process of the obtained gel plaste is stable and feasible,with good adhesive properties,sustained drug release,and favorable in vitro percutaneous permeability,indicating potential clinical application value.

Objective To establish a simultaneous detection approach for 34 emerging contaminants(ECs)in tap water by liquid chromatography-tandem mass spectrometry(HPLC-MS/MS).Human health risk assessment was performed according to the detection results from 43 tap water samples.Methods Tap water samples were concentrated and extracted by solid phase extraction,and then blown to near dry by nitrogen at 40℃.The sample extracts were dissolved in methanol-water solution(95:5,VN)to 0.5 mL for analyzing.Agilent Jet Stream Electrospray Ionization(AJS ESI)and the multiple reaction monitoring(MRM)mode were performed for MS to acquire the data of 34 ECs.A database including precursor ion,product ion and retention times was established accordingly.Results The average linear correlation coefficients(r)of 34 kinds of ECs was 0.995 9.The limits of detection were 0.01~0.60 ng/L and the recoveries were between 60.7%and 119.8%.The intra-group precisions were between 0.05%~9.89%and the intra-day precisions were between 0.20%~14.40%for the spiked samples.The method was applied to analyze 43 tap water samples and a total of 15 ECs were detected.According to the results,the detection rate of caffeine was the highest(84%),and the concentration range was ND~74.42 ng/L.Among all the ECs detected,1,2,3-benzotriazole had the highest concentration(ND~361.15 ng/L),where detection rate was 44%.Humans may be exposed to these ECs by drinking the tap water.The human health risk assessments of 12 kinds of ECs were carried out,however,the estimated risk was negligible(risk quotient<0.01).Conclusion The method is simple,highly sensitive and selective,and could meet the detection needs of ECs at trace level in tap water.There was no human health risk posed for ECs identified in 43 tap water samples analyzed by this method.
