AIM: To evaluate the performance of three distinct large language models(LLM), including GPT-3.5, GPT-4, and PaLM2, in responding to queries within the field of ophthalmology, and to compare their performance with three different levels of medical professionals: medical undergraduates, master of medicine, and attending physicians.METHODS: A total of 100 ophthalmic multiple-choice tests, which covered ophthalmic basic knowledge, clinical knowledge, ophthalmic examination and diagnostic methods, and treatment for ocular disease, were conducted on three different kinds of LLM and three different levels of medical professionals(9 undergraduates, 6 postgraduates and 3 attending physicians), respectively. The performance of LLM was comprehensively evaluated from the aspects of mean scores, consistency and confidence of response, and it was compared with human.RESULTS: Notably, each LLM surpassed the average performance of undergraduate medical students(GPT-4:56, GPT-3.5:42, PaLM2:47, undergraduate students:40). Specifically, performance of GPT-3.5 and PaLM2 was slightly lower than those of master's students(51), while GPT-4 exhibited a performance comparable to attending physicians(62). Furthermore, GPT-4 showed significantly higher response consistency and self-confidence compared with GPT-3.5 and PaLM2.CONCLUSION: LLM represented by GPT-4 performs well in the field of ophthalmology, and the LLM model can provide clinical decision-making and teaching aids for clinicians and medical education.

Needle-free injection technology (NFIT) refers to the drug delivery systems in which drugs are propelled as high-speed jet streams using any of the pressure source to penetrate the skin to the required depth. NFIT is a promising drug delivery system as it enables the injection of liquids, powders, and depot/projectiles, and has the advantages of preventing needle stick accidents, improving drug bioavailability, eliminating needle-phobia, increasing vaccine immunity, simplifying operations and is convenient for patients to use. NFIT and its research background, the structure and classification of needle-free jet injectors (NFJI), drugs that can be delivered using NFJI and the factors affecting the injection effect are comprehensively reviewed in this paper. The limitations and potential development directions are summarized to provide a theoretical basis for the application and development of NFIT.

Objective To retrospectively analyze of factors influencing early preterm birth(EPB)and late preterm birth(LPB)in pregnancy women with placenta previa complicated by placenta accreta spectrum disorders(PAS),and assess maternal and infant outcomes.Methods We included 590 cases of pregnancy women with placenta previa complicated by PAS who underwent cesarean sections at five hospitals in Wuhan and Xianning cities between January 2018 and June 2021.These patients were divided into three groups based on delivery gesta-tional age:EPB,LPB,and term birth(TB).A multiple logistic regression model was employed to analyze the risk factors associated with EPB and LPB.Additionally,differences in early maternal and infant outcomes among these groups were examined.Results Among 590 pregnancy women with placenta previa complicated by PAS,the proportions of EPB and LPB were 9.7%and 54.4%.The use of uterine contraction inhibitors prior to cesarean section,vaginal bleeding,and previous cesarean sections history were identified as risk factors for both EPB and LPB.The proportion of severe postpartum hemorrhage was comparable between the EPB group and the LPB group;however,the incidence of neonatal asphyxia,low birth weight infants,and the rate of newborns transferred to the Neonatal Intensive Care Unit(NICU)within 24 hours after cesarean delivery were significantly higher in the EPB group compared to the LPB group.Conclusions Placenta previa complicated by PAS predominantly leads to LPB.The history of prior cesarean sections,uterine contractions,and vaginal bleeding prior to cesarean section,are sig-nificantly associated with both EPB and LPB.During the perinatal period,efforts should be made to extend gesta-tional weeks under close monitoring to minimize the incidence of premature births and thereby improve early mater-nal and infant outcomes.

Objective: To describe the prevalence of alcohol consumption and the burden of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption in adults aged ≥20 years in 31 provinces in China from 2005 to 2018. Methods: Data from several national representative surveys was used to estimate provincial alcohol exposure level of adults aged ≥20 years from 2005 to 2018 by using kriging interpolation and locally weighted regression methods. Global disease burden research method and data, and China's death cause surveillance data were used to calculate the population attributable fraction (PAF) of hemorrhagic stroke and hypertensive heart disease and the deaths due to alcohol consumption in men and women aged ≥20 years in 31 provinces in China. China census data of 2010 were used to calculate the attributable standardized mortality rate. Results: In 2005 and 2018, the prevalence of alcohol consumption was 58.7% (95%CI: 57.8%-59.5%) and 58.4% (95%CI: 57.6%-59.3%), respectively, in men and 17.0% (95%CI: 16.6%-17.4%) and 18.7% (95%CI:18.1%-19.3%), respectively, in women. The daily alcohol intake was 24.6 (95%CI: 23.8-25.3) g and 27.7 (95%CI: 26.8-28.7) g, respectively, in men and 6.3 (95%CI: 6.0-6.5) g and 5.3 (95%CI: 5.0-5.6) g, respectively, in women. Alcohol exposure level was higher in the provinces in central and eastern China than in western provinces. The lowest exposure level was found in northwestern provinces. From 2005 to 2018, the PAF of hemorrhagic stroke death due to alcohol consumption increased from 5.5% to 6.8%, the attributable deaths increased from 50 200 to 59 100, while the PAF of hypertensive heart disease death due to alcohol consumption increased from 7.0% to 7.7%, the attributable deaths increased from 15 200 to 29 300. The PAF of hypertensive heart disease and hemorrhagic stroke was higher in men than in women, and in central and eastern provinces than in western provinces. In 2018, the standardized mortality rates of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption were 4.58/100 000 and 2.11/100 000, respectively. Conclusions: The prevalence of alcohol consumption in men and daily alcohol intake of drinkers were relatively high in China, especially in eastern provinces. Alcohol exposure level was lower in women than in men. Regional measures should be taken to reduce the alcohol intakes in men and current drinkers in order to reduce the health problems caused by alcohol consumption.

OBJECTIVE:
Circular RNAs (circRNAs) participate in several important pathological processes and have been used in the diagnosis and treatment of various diseases. This study aimed to investigate the role of circRNAs in neural tube defects (NTDs).
METHOD:
We characterized circRNA-associated competitive endogenous RNA (ceRNA) networks in brain tissue of low folate -induced NTDs mouse at embryonic day 13.5 by high-throughput sequencing. The expression levels of Circzfp644, miR-20-5p and Gas7 were detected by RT-PCR. Gas7 and Circzfp644 functions were determined by miRNA-mimics and inhibitors in mouse teratocarcinoma cells (F9 cells), and luciferase gene reporter assay was assessed in the F9 cells. In addition, the expression levels of Circzfp644, miR-20-5p and Gas7 were determined by Nanostring in human NTDs tissues.
RESULTS:
We detected 57 circRNA transcripts, 16 miRNAs, and 148 mRNAs that were significantly dysregulated in NTDs brain tissues compared with their expression levels in control (normal) tissues. Circzfp644 shared miRNA response elements with the growth arrest specific 7 ( Gas7) gene and competitively bound with miR-20-5p to increase the expression of Gas7. Downregulation of Circzfp644 and Gas7 and upregulation of miR-20-5p were found in human NTD tissue.
CONCLUSION
This study provides new perspectives on the role of circRNAs in nervous system development and the pathogenesis of NTDs.

Objective:To observe the clinical characteristics and therapeutic effect of reactivation of retinopathy of prematurity (ROP) patients after intravitreal injection of ranibizumab (IVR).Methods:A retrospective case series study. Eleven children with ROP (21 eyes) who were reactivated after IVR in Shenzhen Eye Hospital from January 2019 to October 2021 were included in the study. Among them, there were 6 males (11 eyes) and 5 females (10 eyes), with the gestational age of (27.6±2.2) weeks and birth weight of (1 034.6±306.5) g. At the first IVR treatment, 14 eyes (63.7%, 14/22) had acute ROP (AROP), 8 eyes (36.3%, 8/22) had threshold lesions. Post-reactivation treatments include IVR, retinal laser photocoagulation (LP), or minimally invasive vitrectomy (MIVS). The follow-up time after treatment was 12 to 18 months. Birth gestational age, birth weight, treatment method, corrected gestational age at treatment, lesion stage before and after treatment, lesion reactivation and regression time were recorded. The clinical characteristics and efficacy were observed and analyzed.Results:The time from initial IVR treatment to reactivation was (8.2±3.5) weeks. The corrected gestational age of the child was (43.62±4.08) weeks. In 21 eyes, AROP, threshold lesion, prethreshold lesion, and stage 4 lesion were in 2, 4, 12, and 3 eyes, respectively. The patients were treated with IVR, LP, IVR+LP, IVR+MIVS in 2, 13, 4 and 2 eyes, respectively. After the first reactivation treatment, the time of regression and stability was (8.4±4.9) weeks after treatment. There were 5 eyes with secondary reactivation of the lesion, and the lesion stages were stage 3, stage 4a and stage 5 in 2, 1 and 2 eyes, respectively. The mean reactivation time was (19.3±6.0) weeks after the last treatment. The patients in stage 3, stage 4a and stage 5 were treated with LP, LP+MIVS and IVR, respecitively, and the lesions subsided steadily during follow-up. At the last follow-up, 19 out of 21 eyes showed complete regression of the lesions, stable photocoagulation, regression of crista-like lesions, no additional lesions, and retinal leveling. All retinal detachment was "funnel-shaped" in 2 eyes.Conclusions:The lesion reactivation of AROP after IVR treatment is more common. The early reactivation rate is higher after treatment. There is a possibility of reactivation twice after re-treatment.

ObjectiveTo explore the action mechanism of Linggan Wuwei Jiangxintang on the treatment of lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice. MethodTraditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), GeneCards, DisGeNET, and Herb databases were combined with clinical data from Gene Expression Omnibus (GEO) to screen the key targets of Linggan Wuwei Jiangxintang in the treatment of ALI. The protein-protein interaction (PPI) network was constructed to screen the core targets, and gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment analyses were performed. The mouse ALI model was established by LPS induction to verify the effect and key targets of Linggan Wuwei Jiangxintang on the treatment of ALI. The expression levels of Toll-like receptor 4 (TLR4), nuclear transcription factor-κB p65 (NF-κB p65), and phosphorylated NF-κB p65 (NF-κB p-p65) in lung tissue were detected by Western blot. ResultThe analysis showed that the treatment of ALI with Linggan Wuwei Jiangxintang was related to 10 core targets such as interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and JUN, involving TNF signaling pathway, Toll-like receptor signaling pathway, NF-κB signaling pathway, etc. The animal experimental results show that Linggan Wuwei Jiangxintang can reduce lung injury, improve the pathological state of ALI mice, significantly reduce the expression of TNF-α and IL-6 in serum, increase the activity of total superoxide dismutase (T-SOD) and catalase (CAT) in lung tissue, and reduce the expression levels of JUN, TLR4, NF-κB p65, and NF-κB p-p65 proteins in lung tissue. ConclusionLinggan Wuwei Jiangxintang can inhibit LPS-induced inflammation and oxidative damage in ALI mice, and its mechanism may be related to the inhibition of TLR4/NF-κB signaling pathway and the reduction of inflammatory factors such as TNF-α and IL-6.

ObjectiveTo assess the value of apparent diffusion coefficient (ADC) in the treatment of uterine fibroid using magnetic resonance guided focused ultrasound surgery (MRgFUS). MethodsThe MRI and clinical data of 56 patients with uterine fibroid before, at 3 and 6 months after MRgFUS treatment, at Foshan Hospital of Traditional Chinese Medicine from December 2018 to October 2022, were retrospectively analyzed. The correlation between the ADC value and lesion volume, symptoms severity score (SSS) and uterine fibroid symptoms quality of life questionnaire (UFS-QOL) were analyzed. ANOVA was used to compare the differences in related parameters before and after treatment, and Pearson’s method was performed to analyze data correlation. ResultsThere were significant differences in ADC value [(1.11±0.13), (1.84±0.09), (2.12±0.24),×10-3/(mm2/s)], lesion volume (102±35.30, 56.70±18.88, 46.93±18.99,cm3), SSS (36.73±11.74, 21.77±10.21, 17.66±9.30) and UFS-QOL score (59.05±17.48, 76.54±16.50, 82.46±12.37) between before treatment and each time point after treatment (F value was 557.837, 73.589, 53.976 and 37.606, respectively, all P<0.05). The ADC values were negatively correlated with lesion volume and SSS, and positively correlated with UFS-QOL score, with correlation coefficients of -0.586, -0.630 and 0.592, respectively (all P<0.05). ConclusionThe ADC value has clinical significance for the treatment of uterine fibroid using MRgFUS.
