Objective: To explore the current status of hyperopic reserve and its related factors among non-myopia preschool and primary school students aged 5 to 12 years in Guangdong Province, so as to provide a basis for formulating intervention strategies for the pre myopia stage of children. Methods: From October to December 2023, by using stratified cluster random sampling method, a survey on hyperopic reserve among preschool children and primary school students in Guangdong were conducted. And a total of 10 567 children from the senior class of kindergarten to the sixth grade of primary school who completed autorefraction measurements with and without cycloplegia and the questionnaire survey were included in the study. The prevalence characteristics of low hyperopic reserve among non-myopia children were analyzed, and multivariable Logistic regression was used to analyze the related factors. Results: The prevalence rate of low hyperopic reserve among 8 790 non-myopia children was 62.4%. The average spherical equivalent (SE) for children aged 5 to 12 years was 0.88 (0.25, 1.25)D, decreasing from 1.13 ( 0.75 , 1.50)D in senior kindergarten to -1.00 (-2.50, 0.38)D in sixth grade, with the difference was statistically significant ( H=2 475.3, P <0.01). Multivariable Logistic regression analysis, after adjusting for confounders including gender, urban and rural, and grade, revealed that parental myopia was a risk factor for low hyperopic reserve in the preschool stage (one parent with myopia: OR=1.62, 95%CI =1.35-1.93; both parents with myopia: OR=2.05, 95%CI = 1.66 -2.55); in the lower primary school stage, parental myopia (one parent with myopia: OR=1.46, 95%CI =1.27-1.68; both parents with myopia: OR=1.58, 95%CI =1.33-1.89), frequently or always reading or using electronic screens while lying down or on one s stomach ( OR=1.43, 95%CI =1.13-1.81), and never or occasionally maintaining a viewing distance of over 3 meters when watching TV/playing video games ( OR=1.34, 95%CI =1.04-1.72) were risk factors; in the higher primary school stage, failing to take a break every hour during near work ( OR=1.79, 95%CI =1.16-2.75) was a risk factor (all P <0.05). Conclusions The emmetropization of children aged 5-12 years in Guangdong Province is accelerated, and non-myopia children generally exhibit insufficient hyperopic reserve. The contributing factors for insufficient hyperopia reserve in non-myopia children vary across different educational stages, necessitating targeted precision interventions.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Objective To explore the value of ultrasound deep learning(DL)model for diagnosis and classification of cystocele.Methods Totally 696 female patients who underwent pelvic floor ultrasound were retrospectively collected and divided into model development dataset(n=576)and test set(n=120).The former included 432 cases of cystocele and 144 cases of non-cystocele,while the latter included 90 cases of cystocele and 30 cases of non-cystocele.Patients in model development dataset were randomly divided into training set(n=460,including 345 cases of cystocele and 115 cases of non-cystocele)and validation set(n=116,including 87 cases of cystocele and 29 cases of non-cystocele)at the ratio of 8∶2.DL model was trained and established using Vision Transformer architecture based on pelvic floor ultrasound data in training and validation sets for diagnosis and classification of cystocele(non-or Green Ⅰ,Ⅱ and Ⅲ type).Taken diagnostic results of senior ultrasound physicians as standard,the diagnostic efficacy of DL model was evaluated,and its diagnostic efficacy and efficiency were compared with those of 2 junior ultrasound physicians.Results The macro average precision,F1 score,area under the curve(AUC)and overall accuracy of DL model for diagnosis and classification of cystocele in validation set was 90.84％,89.28％,0.97 and 89.66％,respectively,while in test set was 80.85％,79.92％,0.92 and 80.00％,respectively.The overall diagnostic accuracy of 2 junior ultrasound physicians for diagnosis and classification of cystocele in test set was 70.00％(84/120)and 68.33％(82/120),respectively,both lower than that of DL model(P=0.023,0.011).The diagnostic time of DL model was 0.098 s for each case,of junior ultrasound physicians was 46(36,56)s for each case,the former had better diagnostic efficacy(P＜0.001).Conclusion Ultrasound DL model could be used for diagnosis and classification of cystocele.

Background Occupational disease diagnosis appraisal is an appeal procedure initiated when a party disagrees with the occupational disease diagnosis conclusion. It is a legal procedure to safeguard the health rights of employees and the legitimate rights and interests of employers. Objective To analyze the data of occupational disease diagnosis appraisal in Shanghai, identify existing problems, and provide suggestions for improving. Methods Statistical analysis was conducted on basic situation, characteristics of workers and employers, disease classification, and consistency between diagnosis and appraisal conclusions of all occupational disease diagnosis appraisal cases from 2012 to 2024. All diagnosis conclusions were named in accordance with the Classified Catalogue of Occupational Diseases included employers were classified according to the Measures for the Statistical Classification of Large, Medium, Small and Micro Enterprises" and the Notice on Adjusting the Provisions for Classifying Enterprise Registration Types; industry classification followed the Industrial Classification for National Economic Activities (GB/T 4754-2017). Results From 2012 to 2024, a total of 260 cases of occupational diseases diagnosis appraisal were closed. The main diagnosis were 138 cases of ear, nose, throat, and oral diseases (53.1%), chemical poisoning (18.8%), and pneumoconiosis and other respiratory diseases (16.2%). The proportion of ear, nose, throat, and oral diseases gradually increased (2022 excluded). The incidence of annual municipal and provincial cases decreased by 76.3% and 85.0% respectively (2024 vs 2012). The consistency rate of conclusions between appraisal and diagnosis gradually increased. The total consistency rates between final appraisals and diagnostic conclusions were 81.5%, and 79.7%, 87.8%, 100.0%, 85.0% for ear, nose, throat, and oral diseases, chemical poisoning, and pneumoconiosis and other respiratory system diseases, respectively. Specifically, the consistency rates were 80.1% and 80.0% for noise-induced deafness and chronic benzene poisoning. In terms of inconsistency reasons, "inconsistent interpretation of standards and excessive discretion in standard application" accounted for 43.8%, followed by "failure to correctly apply standards" (31.3%) and and "discrepancies in occupational exposure history recognition" (15.6%). Conclusion The revisions and improvements of the legal system for occupational disease diagnosis appraisal have played a positive role in improving the consistency of conclusions between appraisal and diagnosis of occupational diseases in Shanghai. It is suggested to further strengthening the publicity and training of occupational disease diagnosis standards to improve the quality of occupational disease diagnosis.

Objective:To assess the efficacy and safety of the treat-and-extend (TAE) regimen and pro re nata (PRN) regimen of intravitreal conbercept in polypoidal choroidal vasculopathy (PCV) patients.Methods:A non-randomized controlled study was performed.Ninety-one patients (91 eyes) diagnosed with treatment-na?ve PCV from October 2016 to January 2019 at Department of Ophthalmology, Peking University People's Hospital were enrolled.All the patients received the intravitreal injection of 0.5 mg conbercept.After the initial treatment, the patients were divided into 3+ PRN group and 3+ TAE group according to their willingness.The follow-up time was one year.All the eyes underwent visual acuity test with ETDRS chart, optical coherence tomography (OCT) examination, fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA). Best corrected visual acuity (BCVA), central retinal thickness (CRT), maximum retinal thickness (MRT), pigment epithelium detachment (PED) height, the number and area of polypoidal lesions, the area of retinal hemorrhage and the area of branching vascular network (BVN) were recorded.Treatment interval and injection frequencies during the one-year follow-up were compared between the two groups.This study adhered to the Declaration of Helsinki.The study protocol was approved by Peking University People's Hospital (No.2020PHB250-01). Written informed consent was obtained from each patient.Results:One-year after treatment, the BCVA improvement in the 3+ PRN group and 3+ TAE group was 5.0(-2.0, 15.0) and 6.0(-1.0, 14.0) letters, respectively, showing no significant difference ( Z=-0.352, P=0.725). No significant differences were found in CRT, MRT and PED height between the two groups ( Z=-0.145, -0.529, -0.985, all at P>0.05). There was no significant difference in polypoidal lesions number, polypoidal lesions area, the number of eyes with different degrees of polyp regression, BVN area and retinal hemorrhage area between the two groups ( Z=-0.502, -0.300, -0.047, -0.265, -1.243, all at P>0.05). After the one-year follow-up, the mean injection frequency of 3+ PRN group was (7.6±0.9) times, which was lower than (8.4±2.0) times of 3+ TAE group, showing a significant difference ( t=2.432, P=0.019). The mean follow-up frequency was (11.3±1.5) times of 3+ PRN group, which was significantly higher than (10.1±1.7) times of 3+ TAE group ( t=3.403, P=0.001). For the 3+ TAE group, 17.1%(6/35) of patients achieved an extension interval of 12 weeks after the first 3 doses, and 48.5%(17/35) of patients achieved an extension interval of 8 weeks or more, with a mean maximum extension interval of (9.5±2.0) weeks.During the follow-up, 10 patients in 3+ PRN group and 8 patients in 3+ TAE group received photodynamic therapy as a rescue treatment. Conclusions:The 3+ PRN and 3+ TAE regimens of intravitreal injection of conbercept combined with photodynamic therapy as a rescue treatment have similar efficacy in visual and anatomical outcomes for PCV patients.3+ TAE regimen has a higher treatment frequency and fewer follow-up visits.

Coronary artery bypass grafting (CABG) is one of the most effective revascularization treatments for coronary heart disease. Secondary prevention strategies, which rely on antiplatelet and lipid-lowering drugs, are crucial after CABG to ensure the durability of revascularization treatment effects and prevent adverse cardiovascular and cerebrovascular events in the medium to long term. Previous research conducted by Professor Zhao Qiang's team from Ruijin Hospital of Shanghai Jiao Tong University, known as the DACAB study, indicated that dual antiplatelet therapy (DAPT, specifically ticagrelor+aspirin) after CABG can enhance venous graft patency. However, it remains uncertain whether DAPT can further improve the medium to long-term clinical outcomes of CABG patients. Recently, the team reported the medium to long-term follow-up results of the DACAB study, termed the DACAB-FE study, finding that DAPT administered after CABG can reduce the incidence of major cardiovascular events over five years and improve patients' medium to long-term clinical outcomes. This article will interpret the methodological highlights and significant clinical implications of the DACAB-FE study.
