Visual system is a critical sensory system in humans and a vital component of the central nervous system, which is responsible for over 80% of external information acquisition.Visual function is a key indicator of overall health.With socioeconomic development, the public has higher expectations for eye health, shifting the focus of eye health initiatives from disease treatment to comprehensive public eye health.Key scientific challenges include how to effectively prevent, diagnose, and treat blindness and visual impairment at an early stage; how to enhance the overall visual quality of patients to ensure not just sight but clear and comfortable vision; and how to meet the public's diverse and multi-tiered eye health needs.Visual science is an interdisciplinary field exploring the development of the visual system, the mechanisms of vision, and brain-related perceptual, cognitive and behavioral processes involving sight.Prioritizing and advancing visual science research is of great significance for promoting comprehensive eye health and implementing the Healthy China Strategy.This article first outlines the concept and research significance of visual science.It then highlights the key scientific questions in visual science pertaining to several major eye diseases, such as myopia, amblyopia, cataract, fundus diseases, glaucoma, and corneal diseases, reviews the historical foundation of visual science research in China, selectively summarizes key achievements and ongoing progress in this field, analyzes the landscape and challenges faced by domestic research, and proposes, to this end, strategies to advance visual science in China.These recommendations are designed to promote visual science research in China and ultimately advance comprehensive eye health.

Objectives:To summarize the characteristics of Fabry′s disease with cardiac involvement.Methods:This was a single-center, cross-sectional, retrospective study. Patients with Fabry disease who were admitted to Zhongda Hospital Affiliated to Southeast University from January 2022 to March 2023 were included. Clinical data, laboratory results, electrocardiogram, echocardiography and cardiac magnetic resonance findings of enrolled patients were collected. Clinical presentations and imaging features of patients with Fabry′s disease with cardiac involvement were summarized and analyzed.Results:A total of 17 patients from 8 families were included, with 9 males and diagnosis age of (44.35±13.72) years. Cardiac involvement and other organ involvement were presented in all patients and the heart was the most vulnerable organ (17/17). 24 h electrocardiogram showed frequent sinus arrhythmia in 3 patients. Echocardiography showed reduced left ventricular ejection fraction in 1 patient, myocardial hypertrophy in 13 patients, and left ventricular wall thickness ≥13 mm in 10 patients. Mitral regurgitation was observed in 11 patients and tricuspid regurgitation in 12 patients. Two patients underwent two-dimensional speckle tracking echocardiography, both revealing reduced regional longitudinal strain of the left ventricle, primarily in the basal segments. Cardiac magnetic resonance showed reduced left ventricular ejection fraction in 2 patients, myocardial hypertrophy in 16 patients, and left ventricular wall thickness≥13 mm in 14 patients. T1 value was reduced in 16 patients, with late gadolinium enhancement observed in 9 patients and “pseudo-normalization” of T1 values in 1 patient. The most susceptible target organ besides the heart was the kidneys (14/17), followed by the central nervous system (9/17). Additional findings inclucling cutaneous angiokeratoma in 4 patients, peripheral neuropathy with burning pain and hypohidrosis or hyperhidrosis in 6 patients, and corneal vortex opacities in 2 patients.Conclusion:The main manifestations of cardiac involvement in Fabry′s disease are decreased cardiac function, left ventricular hypertrophy and myocardial fibrosis. Advanced imaging techniques such as two-dimensional speckle tracking, T1 Mapping, and late gadolinium enhancement are useful in detecting myocardial pathological changes of Fabry′s disease.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective:To investigate the risk factors and their predictive efficacy for early postoperative infection in elderly patients with intertrochanteric femur fracture.Methods:A retrospective cohort study was conducted to analyze the clinical data of 286 elderly patients with intertrochanteric femur fracture admitted to Zhengzhou Orthopedic Hospital between August 2021 and August 2024, including 154 males and 132 females, aged 60-80 years [(72.5±5.8)years]. Fracture involved the left side in 148 patients and the right side in 138 patients. Internal fixation was performed on 214 patients and joint replacement on 72. Based on the occurrence of infection within two weeks postoperatively, the patients were divided into infection group ( n=25) and non-infection group ( n=261). Data were collected from the two groups, including basic information [gender, age, body mass index (BMI), cause of injury, fracture side], admission data (fasting blood glucose, diastolic blood pressure, systolic blood pressure), preoperative data [American Society of Anesthesiologists (ASA) classification, AO classification, serum C-reactive protein (CRP), serum albumin (Alb), serum CRP/Alb ratio, time from injury to surgery], and treatment-related information (surgical type, duration of surgery, intraoperative blood loss, quality of intraoperative reduction, postoperative antibiotic use). Univariate analysis and multivariate Logistic stepwise regression analysis were used to identify independent risk factors for early postoperative infection in elderly patients with intertrochanteric femur fracture. The receiver operating characteristic (ROC) curve was plotted and the area under the curve (AUC) was calculated to evaluate the predictive efficacy of each factor. Results:Univariate analysis showed significant differences between the two groups in fasting blood glucose on admission, preoperative serum CRP, preoperative serum Alb, preoperative serum CRP/Alb ratio, and duration of surgery ( P<0.01). There were no significant differences between the two groups in the remaining variables ( P>0.05). Multivariate Logistic stepwise regression analysis indicated that fasting blood glucose on admission ( OR=2.65, 95% CI 1.32, 5.32, P<0.01), preoperative serum CRP ( OR=1.10, 95% CI 1.04, 1.18, P<0.01), preoperative serum Alb ( OR=0.79, 95% CI 0.70, 0.90, P<0.01), preoperative serum CRP/Alb ( OR=143.78, 95% CI 4.46, 46.77, P<0.01), and duration of surgery ( OR=1.07, 95% CI 1.02, 1.11, P<0.01) were significantly associated with early postoperative infection in elderly patients with intertrochanteric femur fracture. ROC curve analysis showed that the sensitivity and specificity of preoperative serum CRP/Alb in predicting early postoperative infection in elderly patients with intertrochanteric femur fracture were 88.00% and 88.10%, and that the AUC of preoperative serum CRP/Alb prediction was 0.92, significantly greater than the AUC predicted separately by fasting blood glucose at admission, preoperative serum CRP, preoperative serum Alb and duration of surgery (0.76, 0.75, 0.77, 0.76, respectively). The optimal cut-off value for the preoperative serum CRP/Alb ratio was 1.78. Conclusions:Fasting blood glucose on admission, preoperative serum CRP, Alb, CRP/Alb ratio, and duration of surgery are independent risk factors for early postoperative infection in elderly patients with intertrochanteric femur fracture. These factors all possess certain predictive value for early postoperative infection, but the preoperative serum CRP/Alb ratio demonstrates the best predictive efficacy.

Objective:To analyze the causal relationship between circulating inflammatory proteins and the risk of liver cirrhosis by the two-sample Mendelian randomization (MR) method.Methods:Single nucleotide polymorphisms (SNP) strongly associated with 91 plasma inflammatory proteins in genome-wide association studies (GWAS) were used as instrumental variables, and liver cirrhosis was used as the outcome variable. Random-effects inverse variance-weighted (IVW), MR Egger regression, odds ratio ( OR) and its 95% confidence interval were used to evaluate the causal relationship. Simultaneously, sensitivity analysis was performed using MR pleiotropy residuals and outliers (MR-PRESSO) and the Q-test. Results:The causal relationship between the expression of seven specific circulating inflammatory proteins and liver cirrhosis was confirmed by the inverse variance-weighted (IVW) method. The results showed that five plasma inflammatory proteins, including leukemia inhibitory factor [ OR( CI)=0.66, P=9.73×10 -5], interleukin-18 [ OR( CI)=0.76, P=0.013], tumor necrosis factor ligand superfamily member 12[ OR( CI)=0.75, P=0.024], monocyte chemoattractant protein 2 [ OR( CI)=0.89, P=0.036], and C-C motif chemokine 25 [ OR( CI)=0.84, P=0.039], were negatively correlated with cirrhosis and were protective factors for cirrhosis. T cell surface glycoprotein CD5 [ OR ( CI)=1.29, P=0.035] and C-X-C motif chemokine 10 [ OR( CI)=1.32, P=0.043] were positively correlated with cirrhosis and were risk factors for cirrhosis. The results of the MR-PRESSO, Q-test, MR-Egger intercept test, and leave-one-out method all showed the stability. Conclusion:The research results indicated that the increased levels of leukemia inhibitory factor, interleukin-18, tumor necrosis factor ligand superfamily member 12, monocyte chemoattractant protein-2, and C-C motif chemokine 25 were protective factors in the development of cirrhosis, while the increased levels of T cell surface glycoprotein CD5 and C-X-C motif chemokine 10 were risk factors for the development of cirrhosis based on genetic data.
