Background: Active surveillance (AS) has emerged as a viable management strategy for low-risk papillary thyroid microcarcinoma (PTMC), following pioneering trials at Kuma Hospital and the Cancer Institute Hospital in Japan. Numerous prospective cohort studies have since validated AS as a management option for low-risk PTMC, leading to its inclusion in thyroid cancer guidelines across various countries. From 2016 to 2020, the Multicenter Prospective Cohort Study of Active Surveillance on Papillary Thyroid Microcarcinoma (MAeSTro) enrolled 1,177 patients, providing comprehensive data on PTMC progression, sonographic predictors of progression, quality of life, surgical outcomes, and cost-effectiveness when comparing AS to immediate surgery. The second phase of MAeSTro (MAeSTro-EXP) expands AS to low-risk papillary thyroid carcinoma (PTC) tumors larger than 1 cm, driven by the hypothesis that overall risk assessment outweighs absolute tumor size in surgical decision-making. Methods: This protocol aims to address whether limiting AS to tumors smaller than 1 cm may result in unnecessary surgeries for low-risk PTCs detected during their rapid initial growth phase. By expanding the AS criteria to include tumors up to 1.5 cm, while simultaneously refining and standardizing the criteria for risk assessment and disease progression, we aim to minimize overtreatment and maintain rigorous monitoring to improve patient outcomes. Conclusion This study will contribute to optimizing AS guidelines and enhance our understanding of the natural course and appropriate management of low-risk PTCs. Additionally, MAeSTro-EXP involves a multinational collaboration between South Korea and Australia. This cross-country study aims to identify cultural and racial differences in the management of low-risk PTC, thereby enriching the global understanding of AS practices and their applicability across diverse populations.

In recent years, there has been a significant surge in the prevalence of myopia at younger ages in China. Numerous studies have investigated methods for preventing and controlling myopia, including orthokeratology, low-concentration atropine eye drops, light therapy, posterior scleral reinforcement, and traditional Chinese medicine. These approaches can modulate choroidal thickness, blood flow, and target various molecular mechanisms. Orthokeratology and low-concentration atropine demonstrate a thickening effect on the choroid and regulate choroidal blood flow; the use of multi-point defocus control lenses also shows promise in thickening the choroid; the influence of light and light feeding therapy on myopia prevention and control is also reflected in the choroidal thickness and blood flow; and the traditional Chinese medicine has shown good prospect in influencing the microstructure of the choroid for myopia prevention and control. However, the long-term effects of various prevention and control measures on the choroid still need to be explored with a large sample size. This article provides an overview of various methods used to regulate the choroid and prevent myopia. The mechanisms by which these interventions act on the choroid are described to provide new insights and identity novel clinical strategies for myopia management.

Objective To investigate the regulatory effects of plasma-derived exosomal microRNA-1306-5p(miR-1306-5p)on inflammation,apoptosis and oxidative stress in intestinal mucosal epithelial cells in sepsis,and to explore the potential mechanisms.Methods Sepsis plasma-derived exosomes and healthy plasma exo-somes were separated and divided into healthy plasma exosomes group and sepsis plasma-derived exosomes group.The exosomes were observed by electron microscopy,the physical parameters of the two groups of exo-somes were analyzed,and the expression of miR-1306-5p in the exosomes was detected.Intestinal mucosal epi-thelial cells were divided into control group,negative control group of miR-1306-5p mimic(mimic-NC group),miR-1306-5p mimic group(mimic group),mimic combined with overexpression of PLK1 empty vector group(mimic-PLK1-EV group),and mimic combined with overexpression of Polo-like kinase 1(PLK1)group(mimic+PLK1-OE group).Real-time fluorescent quantitative PCR was used to detect the mRNA expressions of miR-1306-5p and PLK1 in each group,and protein imprinting was used to detect the expressions of miR-1306-5p target genes PLK1,caspase 3,B lymphoblastoma-2(Bcl-2)and Bcl2-associated X protein(Bax).Dual luciferase reporter gene assay was used to detect the binding effect of miR-1306-5p and PLK1,and flow cytom-etry was used to detect apoptosis.The expressions of tumor necrosis factor-α(TNF-α),interleukin(IL)-1β,IL-6 and IL-8 in the supernatant of cultured cells were detected by enzyme-linked immunosorbent assay.The expressions of reactive oxygen species(ROS),malondialdehyde(MDA),glutathione(GSH)and superoxide dismutase(SOD)were detected by kit method.Results The plasma derived exosomes of sepsis and healthy plasma were ellipsoid in shape,and there was no significant difference in physical parameters(P＞0.05).Compared with the healthy plasma exosomes group,the expression of miR-1306-5p was up-regulated in the plasma derived exosomes of sepsis group(P＜0.05).PLK1 was identified as the target gene of miR-1306-5p by double luciferase reporter method.Compared with mimic-NC group,the expressions of miR-1306-5p,TNF-α,IL-6,IL-8,IL-1β,caspase3,Bax,ROS and MDA were up-regulated,the apoptosis rate was increased,and the expressions of PKL1,Bcl-2,GSH and SOD were down-regulated in mimic group(all P＜0.05).Compared with mimic+PLK1-EV group,the expressions of TNF-α,IL-6,IL-8,IL-1β,caspase3,Bax,ROS,and MDA were significantly down-regulated,the apoptosis rate was decreased,and the expressions of PKL1,Bcl-2,GSH and SOD were up-regulated in mimic+PLK1-OE group(all P＜0.05).Conclusion Plasma derived exosome miR-1306-5p in sepsis promotes inflammation,apoptosis and oxidative stress damage of intestinal mucosal epi-thelial cells by targeting PKL1 inhibition.

Objective:To explore the effect of virtual reality (VR) technology in postoperative pain management for surgical patients.Methods:The literature on VR technology for relieving postoperative pain in surgical patients was electronically retrieved from eight databases, including PubMed, Web of Science and so on. The search period was from database establishment to November 19, 2023. Two researchers independently screened literature, extracted data, and conducted literature quality evaluation, using RevMan 5.4 for Meta-analysis.Results:A total of 18 articles were included. Meta-analysis results showed that VR technology could reduce postoperative resting pain scores [ MD=-1.13, 95% CI (-1.29, -0.96), P<0.001], postoperative 12 hour pain scores [ MD=-0.49, 95% CI (-0.73, -0.24), P<0.001], postoperative 24 hour pain scores [ MD=-0.73, 95% CI (-0.92, -0.54), P<0.001], postoperative 48 hour pain scores [ MD=-0.69, 95% CI (-0.84, -0.53), P<0.001], postoperative 72 hour pain scores [ MD=-0.37, 95% CI (-0.59, -0.16), P<0.001], and postoperative pain scores during dressing changes [ MD=-1.11, 95% CI (-2.06, -0.16), P=0.02], and could improve patient postoperative comfort [ MD=8.31, 95% CI (6.57, 10.06), P<0.001] . Conclusions:As a non-pharmacological intervention, VR technology can alleviate postoperative pain and improve patient comfort in surgical patients. In the future, large-scale and high-quality research is still needed to further verify the effectiveness of VR technology.

Ketamine,an antagonist of the glutamate N-methyl-D-aspartate(NMDA)receptor,is cur-rently one of the most widely abused psychoactive substances.Prolonged abuse can result in damages to various systems in the body,making it crucial to investigate the regulatory mechanism of ketamine addic-tion and screening related biomarkers.In this study,zebrafish embryos/larvae were initially exposed a-cutely to ketamine.Then,a ketamine addiction model was established in 6-month-old zebrafish through conditioned place preference(CPP)experiments.The zebrafish brain transcriptome was analyzed using RNA-seq,while qPCR and Western blotting were employed to detect the expression of key genes.Results revealed significant reductions in the spontaneous tail coiling,embryo hatching rate,and survival rate of zebrafish embryos in the ketamine-treated group compared to the control group.The distance moved also decreased significantly,from 1904.2 mm in the control group to 319.0 mm in the high dose of ketamine group(300 μmol/L).Conditional positional preference experiments demonstrated that the control ze-brafish did not exhibit significant changes in activity in the CPP tank.In contrast,the ketamine-treated group increased their activity time in the light zone of the tank from 385.2 s before training to 706.4 s af-ter training,representing a 26.8％increase(***P＜0.001).This suggests a preference for ketamine stimulation in zebrafish.KEGG analysis indicated enrichment of differentially expressed genes in the neu-roactive ligand-receptor interaction pathway in the ketamine-treated samples.GSEA analysis further re-veals a significant upregulation of the glutamatergic synapse pathway(NES=1.5).In addition,compared with the control group,the mRNA levels of Grin2b and Gria2 in the ketamine group increased by 4.6 and 1.4 times,respectively,while the protein levels increased by 2.0 and 1.4 times,respectively.These findings suggest that ketamine can induce addiction in zebrafish,potentially through upregulation of the glutamatergic synaptic pathway.
