Antimicrobial resistance (AMR) poses a critical global health threat. This review systematically examines AMR surveillance technology advances, from conventional culture methods to modern molecular diagnostics (e.g., whole-genome sequencing) and artificial intelligence-assisted approaches. It focuses on the current application of mass spectrometry, machine learning predictive models, and real-time surveillance networks. To address challenges including inadequate technical standardization, clinical translation barriers, and data-sharing limitations, we propose integrated "genotype-phenotype" strategies and global standardization framework, while exploring future applications of CRISPR-based portable detection, single-cell sequencing, and blockchain technologies.

Huangqintang, with its accurate efficacy, is a classic formula specialized in treating dysentery recommended and promoted by medical experts from successive generations, and it was included in the Catalogue of Ancient Classic Prescriptions (the Second Batch, Han Chinese medicine prescriptions) published by the National Administration of Traditional Chinses Medicine (TCM) in 2023. The method of bibliometrics was applied in this study to conduct textual research on the classic formula Huangqintang and provide a literature reference for the development of modern preparations of Huangqintang. A total of 2 026 pieces of ancient literature were searched with "Huangqintang" as the key word, and 23 pieces of effective data were selected, involving 15 ancient TCM books. The historic evolution, composition, dosage, origin, processing methods, preparation and decocting methods, efficiency, and application of Huangqintang were carefully reviewed. The results showed that Huangqintang was first recorded in the Treatise on Febrile Diseases written by ZHANG Zhongjing. It has the effect of clearing heat, stopping dysentery, regulating the middle, and downbearing counterflow and has become one of the classic formulas widely used in clinical practice. Because of its accurate efficacy, medical experts from later generations have modified it from its original composition. Though many prescriptions have different names, it is the manifestation of physicians' inheritance and development of the thought of ZHANG Zhongjing. Ancient literature showed this prescription had wide indications yet centered on digestive system diseases such as dysentery and abdominal pain. Modern applications of Huangqintang involve digestive, respiratory, ophthalmology and otolaryngology, gynecological, skin, musculoskeletal system, and connective tissue, and this prescription has great potential in treating ulcerative colitis, diarrhea, acute enteritis, and damp-heat dysentery. Through a systematic textual excavation and review of the ancient literature about Huangqintang, the paper has confirmed its key information, so as to provide a scientific basis for the clinical application and new drug development of classic formulas.

Objective:To evaluate the applicability of a new anti-G capability assessment trainer (AG-CAT) in high-performance (HP) anti-G maneuver training and positive pressure breathing for high-G (PHP) training for pilots.Methods:A total of 142 fighter pilots who were subjected to anti-G maneuver training at Dujiangyan Special Crew Sanatorium of PLA Air Force between January and November 2023 were enrolled. According to the Guidelines for Aviation Physiological Training, 123 pilots underwent both HP anti-G maneuver training and PHP positive pressure breathing training, 15 received only HP training, and 4 received only PHP training. Based on the training devices used, these pilots were divided into AG-CAT group and an anti-G and anti-hypoxia capability detection instrument (GHyCDI) group. The 2 groups were compared regarding the pedal force of lower limbs, blood pressure, and improvement of +G z tolerance during training. Results:Of the 138 pilots undergoing HP training, 88 used AG-CAT and 50 used GHyCDI. One hundred and twenty-seven pilots participated in PHP training, with 73 in the AG-CAT group and 54 in the GHyCDI group. During HP training, the pedal force of left lower limbs in the AG-CAT group was greater than that of the right limbs and of the GHyCDI group ( t=4.38, 2.64, P<0.001, =0.009). In PHP training, the AG-CAT group exhibited greater pedal force in left limbs than in right ones, while the GHyCDI group showed an opposite trend ( t=2.25, 3.37, P=0.029, 0.002). Systolic and diastolic blood pressures during HP training (with or without anti-G suits) were higher in the AG-CAT group than in the GHyCDI group ( t=3.50, 3.72, 2.55, 4.21, P=0.001,<0.001,=0.012,<0.001). Similarly, during PHP training, both systolic and diastolic pressures were higher in the AG-CAT group ( t=2.03, 3.81, P=0.045,<0.001). The AG-CAT group demonstrated superior improvements in +G z tolerance during HP training (without/with anti-G suits: Z=2.14, 3.21, P=0.049, 0.001) and PHP training ( Z=2.56, P=0.010) compared with the GHyCDI group. Conclusions:AG-CAT shows excellent applicability in aviation physiological training of pilots. Its ergonomic design, practical functionalities and enhanced compatibility with personnel protective equipment can better meet training requirements compared to conventional devices.

This study aimed to identify,characterize,and functionally analyze the CYP450 gene fam-ily within Hyalomma asiaticum unfed nymphs(HasiUN)under regular physiological conditions,laying the groundwork for further study into the biosynthesis and metabolism of exogenous sub-stances associated with the CYP450 gene in HasiUN.Through our methods,we identified and characterized HasiUNCYP450 genes.We then annotated them using the gene ontology(GO)and kyoto encyclopedia of genes and genomes(KEGG).This was achieved with the help of bioinforma-tics,based on the transcriptome of 2-week-old HasiUN.Further on,we conducted a preliminary a-nalysis of tissue expression,distribution,and potential function with qRT-PCR and network inter-action predictions.Our analyses showed that 87 HasiUN CYP450 genes,ranging in size from 1089 to 1692 bp,encoded predominantly basic,hydrophilic,and unstable protein sequences.These se-quences had nearly identical numbers of transmembrane regions,both with and without a signal peptide.Phylogenetic and domain analyses indicated that HasiUN CYP450,having a complete CYP450 domain,were distributed among various clans,with most members found in clan 3.CYP20 clans,present in 13 species from 2 families and 7 genera,required either one-host or three-hosts to undergo their full life cycle.MEME analysis results hint at different clans having variations in the amount and combination of motifs.Expression level analysis showed that HasiUN CYP450 was expressed at different levels,with the highest distribution of normally expressed genes in clan 3 and low expression of all mito clan genes.Functional annotation revealed HasiUN CYP450 key as-sociation with biological processes,metabolism,and organismal systems according to the GO and KEGG annotations.Distribution results showed that HasiUN CYP20a1 was expressed in specific tissues,including salivary glands and ovaries.Functional analysis points to CYP20a1's role in UV-induced toxic metabolism,endocrine disruptor metabolism,and hazardous substance metabolism in the nervous system.Our research presents the first analysis of HasiUN CYP450 gene's biological characteristics and expression pattern under normal physiological conditions.Additionally,investi-gations into the distribution and function of a new category,HasiUN CYP20a1,were embarked upon.These findings establish a theoretical foundation for continued functional study of HasiUN CYP45 gene.

Neurofibromas are benign peripheral nerve sheath tumors. It is more common in neurofibromatosis type Ⅰ. However, isolated vagal nerve neurofibroma(VNN) of the neck is extremely rare, and only a few case reports have been reported. Its etiology and pathogenesis are not clear. The diagnosis is mainly based on pathological examination and immunohistochemistry, and surgical resection is the main treatment. This study reports a rare case of giant solitary vagus neurofibroma in the neck. The patient was a 29-year-old female who was found to have a mass on the right side of the neck by physical examination, which was considered to be a vagus nerve tumor by neck ultrasound and imaging examination. The tumor was completely removed during the operation, with the size of about 10.0 cm×2.5 cm, and the patient had no special discomfort. Postoperative pathology and immunohistochemistry confirmed neurofibroma. After surgery, the patient had right vocal cord paralysis, hoarseness, choking and paroxysmal cough. After swallowing function training and voice rehabilitation treatment in the department, the patient recovered satisfactorily. There was no complication and recurrence during the follow-up of 1 year. This article reviews the literature to improve the diagnosis and treatment of solitary vagus neurofibroma in the neck by combining its medical history, imaging features, pathology and immunohistochemistry, and surgical treatment.

OBJECTIVES:
To explore the mediating role of sleep duration in the relationship between depression symptoms and myopia among middle school students.
METHODS:
This study was a cross-sectional research conducted using a stratified cluster random sampling method. A total of 1 728 middle school students were selected from two junior high schools and two senior high schools in certain urban areas and farms of the Xinjiang Production and Construction Corps. Questionnaire surveys and vision tests were conducted among the students. Spearman analysis was used to analyze the correlation between depression symptoms, sleep duration, and myopia. The Bootstrap method was employed to investigate the mediating effect of sleep duration between depression symptoms and myopia.
RESULTS:
The prevalence of myopia in the overall population was 74.02% (1 279/1 728), with an average sleep duration of (7.6±1.0) hours. The rate of insufficient sleep was 83.62% (1 445/1 728), and the proportion of students exhibiting depression symptoms was 25.29% (437/1 728). Correlation analysis showed significant negative correlations between visual acuity in both eyes and sleep duration with depressive emotions as measured by the Center for Epidemiologic Studies Depression Scale (with correlation coefficients of -0.064, -0.084, and -0.199 respectively; P<0.01), as well as with somatic symptoms and activities (with correlation coefficients of -0.104, -0.124, and -0.233 respectively; P<0.01) and interpersonal relationships (with correlation coefficients of -0.052, -0.059, and -0.071 respectively; P<0.05). The correlation coefficients for left and right eye visual acuity and sleep duration were 0.206 and 0.211 respectively (P<0.001). Sleep duration exhibited a mediating effect between depression symptoms and myopia (indirect effect=0.056, 95%CI: 0.029-0.088), with the mediating effect value for females (indirect effect=0.066, 95%CI: 0.024-0.119) being higher than that for males (indirect effect=0.042, 95%CI: 0.011-0.081).
CONCLUSIONS
Sleep duration serves as a partial mediator between depression symptoms and myopia in middle school students.
