Retinal vein occlusion (RVO) is a serious retinal vascular disease, often accompanied by systemic cardiovascular and cerebrovascular diseases, the eye changes include macular edema, retinal ischemia, and even neovascularization, etc. As a common chronic disease of the fundus, it seriously affects patients' vision and quality of life. With the development of optical coherence tomography, the role of choroid in the occurrence and development of RVO has become a research hotspot. The research on the changes of the choroid layer of the eye with RVO has expanded from a simple two-dimensional thickness analysis to a more comprehensive multidimensional observation index such as three-dimensional volume, blood flow density and velocity. In addition, some cutting-edge research combines artificial intelligence algorithm techniques to improve the accuracy and depth of analysis. In the future, it is still necessary to further improve the data of the choroid layer of the eye with RVO, enhance the overall understanding of RVO, and provide new ideas for clinical prevention and treatment of RVO.

Antimicrobial resistance poses a serious threat to human health and is the main cause for the increase in infection-related mortality.Rational and timely use of antimicrobial agents is crucial for improving the prognosis of infected patients,however,overdose and inappropriate use of antimicrobial agents can accelerate the acquisition of drug resistance of pathogenic microorganisms,promote the emergence of new resistance mechanisms,and ultimately lead to the emergence of"superbugs".Therefore,early identification of antimicrobial resistance is of significant im-portance for the rapid diagnosis and precise treatment of infectious diseases.With the development of molecular dia-gnostic techniques,third-generation sequencing(TGS)technique offers innovative solutions for detecting microbial resistance due to its advantages in long read length,easy operation,and rapid detection,significantly promoting ear-ly diagnosis and real-time monitoring of antimicrobial resistance.This review systematically summarizes the research progress of TGS in microbial resistance detection,analyzes its advantages and limitations in rapid detection of resis-tance in viruses,bacteria,and fungi,thus provides new perspectives for the early diagnosis and treatment of patho-genic microbial infections.

Early correction of childhood malocclusion is timely managing morphological, structural, and functional abnormalities at different dentomaxillofacial developmental stages. The selection of appropriate imaging examination and comprehensive radiological diagnosis and analysis play an important role in early correction of childhood malocclusion. This expert consensus is a collaborative effort by multidisciplinary experts in dentistry across the nation based on the current clinical evidence, aiming to provide general guidance on appropriate imaging examination selection, comprehensive and accurate imaging assessment for early orthodontic treatment patients.

Objective To analyze the correlation between plasma Pannexin-1(Panx-1)level and no-reflow after percutaneous coronary intervention(PCI)in patients with ST-segment elevation my-ocardial infarction(STEMI).Methods A prospective trial was performed on 218 STEMI patients who underwent PCI in our hospital from January 2019 to December 2021.According to the blood flow classification of myocardial infarction thrombolysis(TIMI)after PCI,they were divided into normal reflow group(110 cases),slow reflow group(69 cases)and no reflow group(39 cases).The plasma Panx-1 level was determined by ELISA,and the levels of P-selectin,activated glyco-protein Ⅱ b/Ⅲ a(aGP Ⅱ b/Ⅲ a)and platelet-leukocyte aggregates(PLA)were determined by flow cytometry.Results Older age,larger ratio of diabetes mellitus,longer time from symptom onset to PCI,higher platelet count and levels of LDL-C,D-dimer,P-selectin,GP Ⅱ b/Ⅲ a,PNA,PM A,PLyA and plasma Panx-1 were observed in the no-reflow group than the normal and slow reflow groups(P＜0.05).The plasma Panx-1 level in STEMI patients was positively correlated with P-selectin,GP Ⅱ b/Ⅲ a,PNA,PM A and PLyA(P＜0.05,P＜0.01).LDL-C ≥3.20 mmol/L and plasma Panx-1＞0.88 μg/mL were independent risk factors for no-reflow after PCI in STEMI pa-tients(OR=2.198,95％CI:1.252-3.858,P=0.006;OR=16.849,95％CI:4.481-63.357,P=0.000).The AUC value of Panx-1 was 0.826(95％CI:0.744-0.907,P＜0.01)in predicting no re-flux in STEMI patients after PCI.Conclusion The increase of plasma Panx-1 level is closely asso-ciated with the occurrence of no reflow in STEMI patients after PCI,and the protein can be used as a predictive biomarker for the phenomenon.
