1.Pupil abnormalities caused by diabetic neuropathy and their association with diabetic retinopathy
International Eye Science 2026;26(5):811-815
Diabetic retinopathy(DR)and diabetic neuropathy(DN)are common and interrelated chronic complications of diabetes mellitus. With the rising global incidence of diabetes mellitus, early prevention and management of DR are of paramount importance, as it is a leading blinding microvascular lesion. Studies have demonstrated that DN, especially diabetic autonomic neuropathy(DAN), has an earlier pathological process than typical microvascular damage, and the benefits of intensive glycemic control on neuropathy emerge earlier than those on microvascular lesions. The pupil, an organ precisely regulated by the sympathetic and parasympathetic nerves, exhibits dysfunction that serves as a sensitive indicator of DAN, and the degree of pupillary dysfunction is correlated with the severity of DR lesions. This review summarizes the association between diabetes-related neuropathy and DR, focuses on investigating pupillary motility abnormalities induced by DAN and their underlying mechanisms, and analyzes the application value of pupillometry in the assessment of DAN and DR, thus providing novel insights for the early intervention of DR. Nevertheless, the standardization and validity of its clinical application require further in-depth research and verification.

Neuronal injury in glaucoma persists despite effective intraocular pressure (IOP) control, necessitating neuroprotective strategies for retinal ganglion cells (RGCs). In this study, we investigated the neuroprotective role of the γ-hydroxybutyrate analog HOCPCA in a glaucoma model, focusing on its effects on CaMKII signaling, oxidative stress, and neuroinflammatory responses. Retinal tissue from high IOP animal models was analyzed via proteomics. In vitro mouse retinal explants were subjected to elevated pressure and oxidative stress, followed by HOCPCA treatment. HOCPCA significantly mitigated the RGC loss induced by oxidative stress and elevated pressure, preserving neuronal function. It restored CaMKIIα and β levels, preserving RGC integrity, while also modulating oxidative stress and neuroinflammatory responses. These findings suggest that HOCPCA, through its interaction with CaMKII, holds promise as a neuroprotective therapy for glaucoma.

A 15-year-old female with Hodgkin's lymphoma underwent ovarian tissue cryopreservation for preserving fertility in Reproductive Department of Sir Run Run Shaw Hospital,Zhejiang University School of Medical after receiving one course of chemotherapy.During the ovarian tissue cryopreservation,one MⅡmature oocyte and three germinal vesicle oocytes were found.The three immature oocytes underwent in vitro maturation but failed.Ultimately,one mature oocyte and 12 ovarian cortex slices were cryopreserved using vitrification.This case indicates that for patients with established gonadal axis feedback,ovarian tissue cryopreservation may not be the only method for fertility preservation.It is advisable to consider ovarian stimulation and oocyte retrieval for oocyte cryopreservation.Alternatively,for individuals in the ovulation phase of their menstrual cycle,attempting oocyte retrieval before ovarian tissue cryopreservation to obtain mature oocytes from the natural cycle,followed by oocyte cryopreservation,may enhance the likelihood of successful fertility preservation.

Objective To determine the occurrence and baseline predictive factors of early neurological deterioration ( END) among mild ischemic stroke patients.Methods Mild ischemic stroke patients admitted in the hospital were prospectively enrolled.Univariate and multivariate Logistic recession analyses were used to analyze the demographic data, risk factors of ischemic stroke, clinical, brain imaging and laboratory data.Risk factors of END were identified.Results From June 2012 to August 2013, a total of 319 patients with mild ischemic stroke were enrolled, 45 patients (14.1%) of them experienced END.Univariate analysis showed that baseline NIHSS ( U=3522.000,P=0.000), baseline systolic blood pressure (t=2.871,P=0.004), proportion of symptomatic large artery severe stenosis or occlusion (χ2 =52.564,P=0.000) and proportion of large artery atherosclerosis among TOAST subtypes (χ2 =47.287,P=0.000) in END group were significantly higher than those in non-END group. Multivariate logistic regression analysis showed that baseline systolic blood pressure>142 mmHg (1 mmHg=0.133 kPa) (OR=3.954, 95%CI:1.693-9.236, P=0.001), symptomatic large artery severe stenosis or occlusion (OR=3.170, 95%CI:1.170-8.583, P=0.023) and baseline NIHSS (OR=2.038, 95%CI:1.359-3.057, P=0.001) were associated with END.Conclusions About 14.1% of the mild ischemic stroke patients can occur END.Baseline systolic blood pressure>142 mmHg, symptomatic large artery severe stenosis or occlusion and higher baseline NIHSS were the independent risk factors of END.

Objective To investigate the functional outcome in patients with mild ischemic stroke and to identify its risk factors for poor outcome.Methods The patients with mild ischemic stroke treated within 72 hours after onset were enrolled prospectively.According to modified Rankin Scale (mRS) scores at day 90 after onset,the patients were randomly divided into either a poor outcome group (mRS score >2) or a good outcome group (mRS scores 0-2).Univariate analysis and multivariate logistic regression analysis were used to compare and analyze the demographic data,vascular risk factors,clinical data,laboratory data,imaging data,and follow-up data.The risk factors for poor outcome in patients with mild ischemic stroke were identified.Results A total of 253 patients with mild ischemic stroke were enrolled,and 71 of them (28.1%) had poor outcome.Univariate regression analysis showed that the patients' proportions of age (t =2.037,P =0.043),baseline National Institutes of Health Stroke Scale (NIHSS) score (U =4 610.000,P =0.000),baseline mRS score (U =5 723.000,P =0.000),as well as previous history of ischemic stroke (x2 =4.950,P =0.026),severe symptomatic artery stenosis or occlusion (x2 =49.037,P =0.000),large artery atherosclerotic stroke (x2 =34.359,P =0.000),early neurologic deterioration (x2 =45.804,P =0.000),complicated by pneumonia (x2 =12.121,P =0.000) and recurrent ischemic stroke (x2 =14.305,P =0.000) of the poor outcome group were significantly higher than those of the good outcome group.Multivariate logistic regression analysis showed that advanced age (odds ratio [OR] 1.049,95% confidence interval [CI] 1.012-1.086; P =0.008),higher baseline mRS score (OR,2.130,95% CI 1.212-3.743;P=0.009),higher baseline NIHSS score (OR 1.532,95% CI 1.064-2.206; P=0.022),severe symptomatic large artery stenosis or occlusion (OR 7.569,95% CI 3.497-16.380; P=0.000),early neurological deterioration (OR 7.369,95% CI 2.648-20.510; P =0.000) and recurrent ischemic stroke (OR 10.450,95% CI 3.071-35.564; P =0.000) were the independent risk factors for poor outcome.Conclusions More than one fourth of the patients with mild ischemic stroke had poor outcome.Advanced age,higher baseline mRS score,higher baseline NIHSS score,severe symptomatic large artery stenosis or occlusion,early neurological deterioration,and recurrent ischemic stroke were the independent risk factors for poor outcome.
