AIM:To evaluate the clinical efficacy of 0.05% cyclosporine eye drops(Ⅱ)combined with sodium hyaluronate eye drops in treating patients with type 2 diabetes mellitus(T2DM)and moderate-to-severe dry eye.METHODS:A total of 120 T2DM patients(120 eyes)with moderate-to-severe dry eye, treated at the endocrinology and ophthalmology departments at the Affiliated Hospital of Xuzhou Medical University from January 2024 to September 2024, were enrolled in the study. The patients were randomly divided into two groups: combination group [0.05% cyclosporine eye drops(Ⅱ)+ sodium hyaluronate eye drops] and control group(sodium hyaluronate eye drops alone), with 60 cases(60 eyes)in each group. Assessments were conducted at baseline and at 1, 2, and 3 mo post-treatment, including the ocular surface disease index(OSDI), non-contact tear meniscus height(NITMH), first non-invasive tear breakup time(NIBUTf), meibomian gland loss score, lipid layer thickness grade, conjunctival hyperemia grade, and corneal fluorescein staining(FL)score. At 3 mo after treatment, changes in tear inflammatory factors were observed, and corneal subbasal nerve plexus(SBN)morphology/density were analyzed using in vivo confocal microscopy(IVCM).RESULTS:At 1, 2, and 3 mo post-treatment, both groups showed statistically significant increases in NITMH and NIBUTf compared to baseline(all P<0.05), with greater improvement observed in the combination group(both P<0.05). OSDI and FL scores significantly decreased from baseline(all P<0.05), with more pronounced reductions in the combination group(both P<0.05). Meibomian gland loss scores showed no significant improvement in either group(all P>0.05). At 3 mo after treatment, tear levels of interleukin 6(IL-6)and matrix metalloproteinase-9(MMP-9)significantly decreased in both groups(all P<0.001), with a greater reduction noted in the combination group(both P<0.001). The combination group displayed increased corneal nerve branch density and nerve fiber density, along with decreased nerve tortuosity and dendritic cell(DC)density compared to baseline(all P<0.001), while the control group did not show significant changes(all P>0.05).CONCLUSION: The combination of 0.05% cyclosporine eye drops(Ⅱ)and sodium hyaluronate eye drops significantly improves clinical outcomes in T2DM patients with moderate-to-severe dry eye. This treatment effectively alleviates ocular surface inflammation, restores corneal nerve morphology and density, and demonstrates a favorable safety profile.

AIM: To explore the risk factors associated with diabetic retinopathy(DR)based on ultra-widefield swept-source optical coherence tomography angiography(UWF-SS-OCTA), and to establish a clinical prediction model.METHODS:A total of 235 patients(235 eyes)with type 2 diabetes mellitus who were treated in the Affiliated Hospital of Xuzhou Medical University from July to November 2024 were selected as the research objects. According to the presence or absence of DR, they were divided into 120 cases(120 eyes)in non-DR group(NDR group)and 115 cases(115 eyes)in non-proliferative DR group(NPDR group). Data on general characteristics, laboratory tests, and OCTA results were collected for both groups. Univariate analysis was employed to identify DR-related risk factors. Logistic regression analysis was conducted to analyze these risk factors and to establish a DR prediction model. The efficacy of the model was evaluated using the receiver operating characteristic(ROC)curve, calibration curve, and decision curve analysis(DCA).RESULTS: The duration of diabetes, fasting blood glucose, blood urea nitrogen(BUN), history of hypertension, and the choroidal vascular index(CVI)were found to be statistically significant in the model(all P<0.05). Specifically, the duration of diabetes, fasting blood glucose, BUN, and history of hypertension were identified as risk factors for DR among diabetic patients, while CVI was recognized as a protective factor. The area under the curve for the model predicting the probability of DR was 0.898(0.859-0.938), with a diagnostic threshold of 0.438. The corresponding sensitivity and specificity were 87.8% and 78.3%, respectively, indicating that the model possesses high predictive value for the occurrence of DR.CONCLUSION: The duration of diabetes, fasting blood glucose, BUN, history of hypertension, and CVI are significantly correlated with DR. The established prediction model demonstrates a substantial screening capability for DR.

Objective:To investigate the correlation between hearing loss and microvascular complications in diabetes.Methods:This cross-sectional study conducted the data from 572 patients with diabetes hospitalized in the Endocrinology Department of the General Hospital of Southern Theater Command from September 2022 to July 2023. All participants underwent electrical audiometry and acoustic immittance in the ENY department. Based on the audiometric results, participants were categorized into normal hearing group and hearing loss group. Additionally, 572 non-diabetic patients from the outpatient department were enrolled as the non-diabetic group. The general information and laboratory results were collected and compared using t test, rank sum test or χ2 test. Binary logistic regression analysis was used to evaluate the association of diabetic hearing loss with diabetic kidney disease(DKD), diabetic retinopathy (DR), and diabetic peripheral neuropathy (DPN). Results:Among 572 patients with diabetes, 429 suffered from hearing loss and 143 were normal. χ2 test showed significant differences in combined DKD and DPN between two groups, but not in DR. Multivariate binary logistic regression analysis identified DKD and DPN as risk factors for hearing loss, but no correlation was found with DR. Conclusion:Diabetic patients with DKD or DPN should be monitored for potential hearing loss. Early screening and treatment are crucial to prevent severe hearing impairment.

Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous syestem (CNS) triggered by an autoimmune mechanism, which is the main cause of neurological disability in young people. In MS, a variety of glial cells participate in the pathogenesis and development of the disease, and oligodendrocytes (OL) and myelin cytes are destroyed by autoimmune mediated inflammation. Impaired OL production of oligodendrocyte progenitor cells (OPC) leads to persistent demyelination, myelin fragment accumulation and axonal injury, with clinical manifestation of CNS disability. Microglia (MG), which is involved in the inflammatory response and removal of myelin debris, plays a pivotal role in OPC differentiation and OL maturation, thereby directly or indirectly influencing the process of myelin regeneration. An interactive mechanism exists between these 2 components. The comprehension of the interrelationship between the 2 factors can provide enhanced insights into the pathogenesis of MS and facilitate the development of novel therapeutic strategies, thereby addressing pivotal scientific challenges encountered in clinical management of MS. Therefore, this review summarizes the dynamic changes of microglia in MS and its classic animal models, explores the internal relationship between MG and OL in this process, and focuses on the beneficial effects of targeted regulation of microglia, thereby promoting OPC differentiation and myelin regeneration, in order to provide a new research direction for MS treatment.

Purpose: This study investigated whether professional identity predicts learning burnout among Chinese nursing students, and whether resilience moderates this relationship. Methods: This cross-sectional study recruited 635 students from a nursing college at a medical university in Hefei, China. Data were collected using the professional identity questionnaire, learning burnout scale for college students, and 10-item Connor-Davidson Resilience Scale. Pearson’s correlation analysis was used to investigate the relationships between variables. The mediation effect was evaluated using linear regression and the bootstrap method in SPSS. Results: Nursing students exhibited intermediate learning burnout levels (score: 54.95 ± 10.42). Professional identity was positively correlated with psychological resilience (r = .42, p < .001), whereas learning burnout was negatively correlated with professional identity (r = - .54, p < .001) and psychological resilience (r = -.57, p < .001). Psychological resilience mediated the relationship between professional identity and learning burntout to the tune of 32.8%. Conclusion Psychological resilience mediates the relationship between professional identity and learning burnout. Thus, nursing educators can mitigate student burnout by developing their students' professional identities and psychological resilience.
