Diabetes poses a considerable global health challenge, with varying levels of diabetes knowledge among healthcare professionals, highlighting the importance of diabetes training. Large Language Models(LLMs)provide new insights into diabetes training, but their performance in diabetes-related queries remains uncertain, especially outside the English language like Chinese. We first evaluated the performance of ten LLMs: Chat GPT-3.5, Chat GPT-4.0, Google Bard, Lla MA-7B, Lla MA2-7B, Baidu ERNIE Bot, Ali Tongyi Qianwen, Med GPT, Huatuo GPT, and Chinese Lla MA2-7B on diabetes-related queries, based on the Chinese National Certificate Examination for Primary Diabetes Care in China(NCE-CPDC) and the English Specialty Certificate Examination in Endocrinology and Diabetes of Membership of the Royal College of Physicians of the United Kingdom. Second, we assessed the training of primary care physicians(PCPs) without and with the assistance of Chat GPT-4.0 in the NCE-CPDC examination to ascertain the reliability of LLMs as medical assistants. We found that Chat GPT-4.0 outperformed other LLMs in the English examination, achieving a passing accuracy of 62.50%, which was significantly higher than that of Google Bard, Lla MA-7B, and Lla MA2-7B. For the NCE-CPFC examination, Chat GPT-4.0, Ali Tongyi Qianwen, Baidu ERNIE Bot, Google Bard, Med GPT, and Chat GPT-3.5 successfully passed, whereas Lla MA2-7B, Huatuo GPT,Chinese LLa MA2-7B, and Lla MA-7B failed. Chat GPT-4.0(84.82%) surpassed all PCPs and assisted most PCPs in the NCE-CPDC examination(improving by 1%–6.13%). In summary, LLMs demonstrated outstanding competence for diabetes-related questions in both the Chinese and English language, and hold great potential to assist future diabetes training for physicians globally.

PURPOSE:To evaluate the 12-month myopia control efficacy of an Asymmetric Multi-point Defocus Technique (AMDT) spectacle lens. DESIGN:Double-masked randomized controlled trial. PARTICIPANTS:140 participants completed all visits (mean age, 10.6 ± 1.5 years; 50% female), with SER between -5.00 and -0.75 diopter (D), astigmatism ≤ 1.50 D and anisometropia ≤ 1.50 D. METHODS:144 children recruited from two ophthalmic centers aged 8-13 years with myopia of -0.75 D to -5.00 D were randomized (1:1) to wear AMDT or single vision (SVL) spectacle lenses. Cycloplegic spherical equivalent refraction (SER) and axial length (AL) were measured at the baseline, 6-month, and 12-month visits. Adaptation and visual performance questionnaires were administered during the intervention. MAIN OUTCOME MEASURES:The SER change after one year was the primary outcome and the change in AL, visual performance, and ocular parameters after one year were defined as secondary outcomes. RESULTS:After 12 months, the SVL group (n = 69) exhibited mean changes in SER and AL of -0.50 ± 0.06 D and 0.32 ± 0.02 mm, respectively, compared to -0.16 ± 0.06 D and 0.17 ± 0.02 mm (both p< 0.001) in the AMDT group (n = 71). Compared with the SVL group, participants in the AMDT group had significantly less myopia progression by 0.39 D in SER (74%) and 0.17mm in AL (51%) after adjustment for baseline age, baseline SER/AL and ophthalmic center. The correlation between younger age and more rapid AL elongation was more pronounced in the SVL group (r = -0.68, p <0.001), compared to the AMDT group (r = -0.37, p = 0.002). 30 (42.2%) participants in the AMDT group displayed no SER progression after 1-year. No serious adverse events or persistent visual discomfort were observed. CONCLUSION:Compared with SVL, AMDT spectacle lenses significantly reduced SER and AL progression over 1 year, with a favorable safety profile and visual performance. The correlation between age and myopia progression was diminished after AMDT interven

AIM： To observe the effect of exosomes derived from human umbilical cord blood mesenchymal stem cells（h UCMSCs） on the expression of vascular endothelial growth factor-A（VEGF-A） in blue light injured human retinal pigment epithelial（RPE） cells and laser-induced choroidal neovascularization（CNV） in ***： Exosomes were isolated from h UCMSCs and characterized by transmission electron microscope and Western blot. MSCs-derived exosomes were cultured with RPE cells exposed to blue light. The m RNA and protein expression of VEGF-A were determined by real time-polymerase chain reaction（PCR） and Western blot, respectively. Immunofluorescence assay was used for the detection of the expression level of VEGF-A. We injected different doses of MSCs-derived exosomes intravitreally to observe and compare their effects in a mouse model of laserinduced retinal injury. The histological structure of CNV in rats was inspected by hematoxylin-eosin（HE） staining and fundus fluorescein angiography. The expression of VEGF-A was detected by ***： Exosomes exhibited the typical characteristic morphology（cup-shaped） and size（diameter between 50 and 150 nm）. The exosomes marker, CD63, and h UCMSCs marker, CD90, showed a robust presence. In vitro, MSCsderived exosomes downregulated the m RNA（Exo-L： t=6.485, 7.959, 9.286; Exo-M： t=7.517, 10.170, 13.413; Exo-H： t=10.317, 12.234, 14.592, P〈0.05） and protein（Exo-L： t=2.945, 4.477, 6.657; Exo-M： t=4.713, 6.421, 8.836; Exo-H：t=6.539, 12.194, 12.783; P〈0.05） expression of VEGF-A in RPE cells after blue light stimulation. In vivo, we found that the MSCs-derived exosomes reduced damage, distinctly downregulated VEGF-A（Exo-H： t=0.957, 1.382; P〈0.05）, and gradually improved the histological structures of CNV for a better visual function（Exo-L： 0.346, Exo-M： 3.382, Exo-H： 8.571; P〈0.05）. CONCLUSION： MSCs-derived exosomes ameliorate blue light stimulation in RPE cells and laser-induced retinal injury via downregulation of VEGF

A new measure of nystagmus acuity

引用

International Journal of ophthalmology(English edition) 2014年第1期7卷 95-99页

作者： Jun-Ping Yao Zheng Tai Zheng-Qin Yin Department of Ophthalmology Tianyou HospitalWuhan University of Science and Technology Chongqing Key Lab of Visual Damage and Regeneration & Restoration Chongqing Broadcasting Group Department of Ophthalmology Southwest HospitalThird Military Medical University

AIM: To construct a new visual acuity measuring function for congenital nystagmus(CN) patients by studying the relationships between acuity,velocities and positions of the eye. ·METHODS: After assessing the relationship between acuity,movement velocities and positions of the eye separately,a new function,which we call the automated nystagmus acuity function(ANAF),was constructed to measure the visual acuity of CN patients. Using a high-speed digital video system working at 500 frames per second,each eye was calibrated during monocular fixation. Twenty-six recorded nystagmus data were selected randomly. Using nystagmus waveforms,the best vision position(foveation period) and visual acuity were analyzed in three groups of subjects,and then all outputs were compared with the well-known expanded nystagmus acuity function(NAFX) and ANAF. Standard descriptive statistics were used to summarize the outputs of the two programs. ·RESULTS: Foveation periods were brief intervals in the CN waveform when the image was on or near the fovea and eye velocity was relatively slow. Results showed good visual acuity happened during the period when velocity was low and the eye position was near the zero position,which fitted the foveation periods. The data analyzed with NAFX and ANAF had a correlation coefficient of 0.934276,with an average error of-0.00973. · CONCLUSION: The results from ANAF and NAFX analyses showed no significant difference. The NAFX manually identifies foveation eye positions and produces accurate measurements. The ANAF,however,can be calculated simply using the factors eye position andvelocity,and it automatically calculates the ANAF without the need to manually identify foveation eye positions.
