The prevalence of dry eye among children has been progressively increasing each year; however, clinical diagnosis remains challenging due to the unique physiological attributes of the pediatric tear film functional unit, as well as symptoms that are often atypical and clinical signs that differ from those seen in adults. In healthy children, tear secretion is generally greater, the meibomian gland structure is typically more intact, and the meibum composition and physicochemical properties are more favorable for the maintenance of tear film stability. Compared to adults, the etiology of pediatric dry eye is more frequently associated with meibomian gland dysfunction, allergic ocular conditions, orthokeratology lens wear, environmental influences, such as growing screen time, and systemic disorders. Affected children frequently exhibit non-specific symptoms such as excessive blinking or rubbing of the eyes, which may be overlooked due to their limited ability to verbalize discomfort. Clinical signs can include conjunctival hyperemia, decreased tear meniscus height, and corneal epithelial punctate lesions, though these tend to be milder or less distinct compared with adults. Diagnostic requires the use of age-appropriate tear metrics, such as the Schirmer test and tear film breakup time, alongside ocular surface evaluation, with particular attention to features specific to children that distinguish it from dry eye in adults. Going forward, it is essential to establish and validate pediatric-specific diagnostic criteria to improve ocular surface health and maximize visual quality in this vulnerable population.

Objective To investigate the risk factors for abnormal cardiac function in patients with hepatolenticular degeneration （also known as Wilson disease ，WD） using cardiac magnetic resonance imaging （CMR）， and to identify indicators with a value for early diagnosis. Methods Patients diagnosed with WD were randomly selected to undergo CMR examination， and based on CMR findings， they were divided into abnormal group and normal group. A univariate analysis was used to obtain potential risk factors， then a multivariate logistic regression analysis was performed for variables with a significant difference， and finally the receiver operating characteristic （ROC） curve analysis was performed for the independent risk factors identified. Results A total of 42 WD patients were enrolled， with 21 in the abnormal CMR group and 21 in the normal CMR group. Compared with the normal CMR group， the abnormal CMR group had a significantly higher age and significantly higher levels of total bilirubin， serum copper， and peak 24-hour urinary copper during treatment. The multivariate Logistic regression analysis showed that white blood cell count （WBC） （OR=2.927， 95%CI 1.127‒7.839， P=0.028）， serum copper（OR=3.822， 95%CI 1.108‒13.178， P=0.034）， and type Ⅳ collagen （OR=1.097， 95%CI 1.011‒1.191，P=0.027） were independent risk factors for CMR abnormalities in WD patients. The ROC curve analysis showed that among the above three indicators used alone， serum copper had the highest diagnostic value with an area under the ROC curve （AUC） of 0.713， followed by WBC（AUC=0.651） and type Ⅳ collagen （AUC=0.644）， and the combination of these three indicators had significantly higher diagnostic efficacy （AUC=0.869）. Conclusion Serum copper is the single indicator with the highest diagnostic efficacy for CMR abnormalities in WD patients， but the combination of serum copper， WBC， and type Ⅳ collagen has a significantly better diagnostic value in identifying abnormal cardiac function in WD patients.

Objective To investigate the clinical features and key diagnostic points of aceruloplasminemia （ACP）， as well as the features of a novel pathogenic mutation. Methods A systematic analysis was performed for the clinical data of one patient with a confirmed diagnosis of ACP， and a literature review was performed based on related articles in China and globally. Results Based on the clinical features of this patient and the analysis of the family， it was clarified that the homozygous c.1944C>G （p.Ser648Arg） mutation in the Ceruloplasmin （CP） gene could cause ACP and was reported for the first time worldwide. Conclusion ACP is an extremely rare autosomal recessive disease due to abnormal iron metabolism caused by a significant reduction in ceruloplasmin， with the main clinical manifestations of retinopathy， diabetes， ataxia， and cognitive impairment， and genetic testing of the CPgene has a relatively high diagnostic value.

A total of 72 elderly patients with comorbid diabetes and coronary heart disease from different communities who visited the Fenglin Street Community Health Service Center, Xuhui District, Shanghai, from January to June 2023 were selected by convenient sampling method. They were divided into control group and experimental group by random number method, with 36 cases in each group. The control group used the routine health management program, the experimental group used the health management program for elderly patients with comorbid diabetes and coronary heart disease. The clinical indicators (glycated hemoglobin, body mass index, etc), self-management abilities (including those of elderly patients with diabetes and those with coronary heart disease), and quality of life were compared between the two groups.Results:There were 14 males and 22 females in the control group, with an age of (73.67 ± 5.97) years; there were 21 males and 15 females in the experimental group, with an age of (73.33 ± 5.63) years. After intervention, the glycated hemoglobin of patients in the experimental group was (7.03 ± 0.64)%, while that of the control group was (7.42 ± 0.72)%. The difference between the two groups was statistically significant ( t=-2.49, P<0.05).The scores of self-management ability of elderly patients with diabetes and elderly patients with coronary heart disease in the experimental group were (22.66 ± 4.69) and (98.28 ± 13.54) points, which were significantly higher than (20.56 ± 4.05) and (93.00 ± 8.01) points in the control group, the differences were statistically significant ( t=2.03, 2.01, both P<0.05). The score of energy in the experimental group was (35.56 ± 8.68) points, which was higher than that of the control group (28.75 ± 15.18) points, the difference was statistically significant ( t=2.34, P<0.05). Conclusions:Health management programs for elderly patients with comorbid diabetes and coronary heart disease can significantly improve patients′ blood glucose control and enhance their self-management abilities for diabetes and coronary heart disease. However, further validation is needed to improve patients′ blood lipid control level and quality of life.

Objective:To introduce a new design of super-micro flap for endoscopic ear surgery, and to evaluate the application effect of super-micro flap in endoscopic tympanoplasty. Methods:Between January, 2023 and March, 2024, 58 patients（64 ears） with tympanosclerosis underwent tympanoplasty with super-micro flap. Continuous irrigating mode endoscopic ear surgery（CIM-EES） was used to complete type Ⅱ or Ⅲ tympanoplasty with the tragus cartilage with followed up for 12 to 24 months. The operation time, postoperative efficacy and complications were statistically analyzed. Results:Of the 64 ears, 63 ears had primary healing of the tympanic membrane, and 1 ear had cartilage necrosis due to multi-drug resistant bacteria infection. The second operation was performed one year later, and the success rate of operation was 98.40%. The average operation time was （48.40±8.86） minutes. The average hearing threshold of 0.5 kHz to 4.0 kHz before operation was （59.63±10.62） dB HL, and the average air conduction threshold of 0.5 kHz to 4.0 kHz one year after operation was（38.79±10.91） dB HL, which was significantly improved compared with that before operation（P<0.01）. Bone conduction threshold also improved significantly （24.49±8.55） dB HL vs（21.88±7.58） dB HL（P<0.01）. No outer tympanic membrane healing and ear canal scar stenosis occurred. Conclusion:The design of super-micro flap can effectively solve the interference of flap floating during continuous irrigating mode in endoscopic ear surgery, relieve the difficulty of flap reposition, simplify the operation process, help to shorten the operation time, and reduce the possibility of circular scar stenosis of conventional free flap, which provides a new flap design option for endoscopic ear surgery.

Objective: To evaluate the clinical efficacy and safety of micro-percutaneous nephrolithotomy (microPCNL) using Needle-perc in the oblique supine-lithotomy position for treating 1—2 cm lower-pole stones (LPSs)，by comparing it with flexible ureteroscopic lithotripsy (FURL)，so as to identify an effective surgical method for LPSs. Methods: We retrospectively analyzed the clinical data of 56 patients with isolated LPSs of 1—2 cm treated in our hospital during Jan.and Dec.2023.Patients were divided into two groups based on the treatment method：FURL (n=31) and microPCNL (n=25).General information and perioperative data were compared between the two groups. Results: All operations were successfully completed.The operation time was shorter in the microPCNL group than in the FURL group \[(46.5±10.1) min vs.(73.5±18.9) min，P<0.001\].Stone-free rate (SFR) was 92.0% in the microPCNL group and 71.0% in the FURL group (P=0.026).There were no significant differences in the average fall of hemoglobin level，serumc creatinine change level，hospitalization time and postoperative fever between the two groups. Conclusion: MicroPCNL in oblique supine-lithotomy position is a safe and effective treatment for 1-2 cm LPSs，with a higher SFR compared to FURL.

Resveratrol(Res) is a kind of polyphenolic compound, possessing multiple biological activities such as antioxidant, anti-inflammatory, cardioprotective, and anticancer effects. In recent years, the cardiovascular protective mechanism of Res has become a research hotspot. Studies have shown that Res has a protective effect on the cardiovascular system through various pathways, such as inhibiting oxidative stress, regulating ferroptosis of cells, improving ischemia-reperfusion(I/R) injury, regulating lipid metabolism, suppressing inflammatory responses, and enhancing endothelial function. It can also alleviate cardiotoxicity caused by drugs and chemicals. In terms of oxidative stress, Res reduces the level of intracellular reactive oxygen species(ROS) by enhancing the expression of proteins such as silent information regulator 1(SIRT1) and regulating mitochondrial function, thereby alleviating myocardial cell damage. Regarding ferroptosis, Res inhibits the occurrence of ferroptosis by regulating the expression of proteins related to iron metabolism. Res can also improve I/R injury through mechanisms such as activating autophagy and the mitochondrial quality control network. In regard to improving endothelial function, Res protects the function of endothelial cells by regulating multiple signaling pathways, such as downregulating the PREP1-mediated pathway. Res can also regulate lipid metabolism and inhibit the progression of atherosclerosis. In terms of inflammatory responses, Res exerts anti-inflammatory effects through mechanisms such as inhibiting the nuclear factor-kappa B(NF-κB) signaling pathway. In addition, Res has an improving effect on cardiotoxicity caused by different drugs or environmental factors. However, the clinical application of Res still faces limitations such as poor pharmacokinetic properties. In the future, in-depth exploration is needed at multiple levels from basic research to clinical application to clarify the dose-response relationship and standardize the standards of medication regimens with the expectation of providing more effective strategies for the prevention and treatment of cardiovascular diseases.

Depression (Dep) is one of the most common concomitant symptoms of Parkinson's disease (PD), but there is a lack of detailed pathologic evidence for the occurrence of PD-Dep. Currently, the management of symptoms from both conditions using conventional pharmacological interventions remains a formidable task. In this study, we found impaired activation of extracellular signal-related kinase (ERK), reduced levels of transcription and translation, and decreased expression of brain-derived neurotrophic factor (BDNF) in the medial prefrontal cortex (mPFC) of PD-Dep rats. We demonstrated that the abnormal phosphorylation of α-synuclein (pS129) induced tropomyosin-related kinase receptor type B (TrkB) retention at the neuronal cell membrane, leading to BDNF/TrkB signaling dysfunction. We chose SEW2871 as an ameliorator to upregulate ERK phosphorylation. The results showed that PD-Dep rats exhibited improvement in behavioral manifestations of PD and depression. In addition, a reduction in pS129 was accompanied by a restoration of the function of the BDNF/ERK signaling loop in the mPFC of PD-Dep rats.

Schizophrenia (SZ) stands as a severe psychiatric disorder. This study applied diffusion tensor imaging (DTI) data in conjunction with graph neural networks to distinguish SZ patients from normal controls (NCs) and showcases the superior performance of a graph neural network integrating combined fractional anisotropy and fiber number brain network features, achieving an accuracy of 73.79% in distinguishing SZ patients from NCs. Beyond mere discrimination, our study delved deeper into the advantages of utilizing white matter brain network features for identifying SZ patients through interpretable model analysis and gene expression analysis. These analyses uncovered intricate interrelationships between brain imaging markers and genetic biomarkers, providing novel insights into the neuropathological basis of SZ. In summary, our findings underscore the potential of graph neural networks applied to multimodal DTI data for enhancing SZ detection through an integrated analysis of neuroimaging and genetic features.
