Autoimmune hepatitis （AIH） is a chronic inflammatory liver disease. The pathogenesis of AIH remains unclear， but it is mainly autoimmune injury caused by the breakdown of autoimmune tolerance due to the abnormal activation of the immune system， while the specific molecular mechanism remains unknown. Recent studies have shown that abnormal amino acid metabolism plays an important role in the development and progression of AIH. This article reviews the research advances in amino acid metabolic reprogramming in AIH， in order to provide a theoretical basis for amino acid metabolism as a new target for the clinical diagnosis and treatment of AIH.

This paper explores the therapeutic approach for glaucoma based on the concept of "jueyin （厥阴） as the closing phase" from the perspectives of time and space. In traditional Chinese medicine， jueyin governs inward， converging aspect of qi， representing the crucial turning point between the end of yin and the emergence of yang， as well as the transformation between yin and yang. When the closing and descending function of jueyin operates smoothly， it promotes the inward convergence and smooth descent of qi， enabling the internal retention of blood， spirit， and emotions， which nourishes the internal organs and moistens the meridian-sinews. Conversely， dysfunction of this "closing" mechanism results in a disturbance of yin and yang， a mixture of cold and heat， and disharmony of qi and blood. It is proposed that "failure of jueyin to properly close and descend" is a core pathomechanism of glaucoma. From the perspective of spatiotemporal theory， clinical treatment should focus on "regulating the closing function of jueyin and harmonizing yin and yang". The modified Wumei Pill （乌梅丸） is recommended to adjust the ascending-descending and entering-exiting dynamics of jueyin qi transformation， thereby restoring its free flow， achieving yin and yang balance， and ensuring nourishment to the ocular system.

The rapid development of artificial intelligence (AI), especially generative AI (GenAI), has already brought, and will continue to bring, revolutionary changes to our daily production and life, as well as create new opportunities and challenges for diagnostic and therapeutic practices in the medical field. Haihe Hospital of Tianjin University collaborates with the National Supercomputer Center in Tianjin, Tianjin University, and other institutions to carry out research in areas such as smart healthcare, smart services, and smart management. We have conducted research and development of a full-process disease diagnosis and treatment assistance system based on GenAI in the field of smart healthcare. The development of this project is of great significance. The first goal is to upgrade and transform the hospital's information center, organically integrate it with existing information systems, and provide the necessary computing power storage support for intelligent services within the hospital. We have implemented the localized deployment of three models: Tianhe "Tianyuan", WiNGPT, and DeepSeek. The second is to create a digital avatar of the chief physician/chief physician's voice and image by integrating multimodal intelligent interaction technology. With generative intelligence as the core, this solution provides patients with a visual medical interaction solution. The third is to achieve deep adaptation between generative intelligence and the entire process of patient medical treatment. In this project, we have developed assistant tools such as intelligent inquiry, intelligent diagnosis and recognition, intelligent treatment plan generation, and intelligent assisted medical record generation to improve the safety, quality, and efficiency of the diagnosis and treatment process. This study introduces the content of a full-process disease diagnosis and treatment assistance system, aiming to provide references and insights for the digital transformation of the healthcare industry.

Objective To examine the changing prevalence and antimicrobial resistance profiles of Burkholderia cepacia in 52 hospitals across China from 2015 to 2021.Methods A total of 9 261 strains of B.cepacia were collected from 52 hospitals between January 1,2015 and December 31,2021.Antimicrobial susceptibility of the strains was tested using Kirby-Bauer method or automated antimicrobial susceptibility testing systems according to a unified protocol.The results were interpreted according to the breakpoints released in the Clinical & Laboratory Standards Institute(CLSI)guidelines(2023 edition).Results A total of 9 261 strains of B.cepacia were isolated from all age groups,especially elderly patients.The proportion was 11.1％(1 032 strains)in children,significantly lower than the proportion in adults.About half(46.5％,4 310/9 261)of the strains were isolated from patients at least 60 years old and 42.3％(3 919/9 261)of the strains were isolated from young adults.Most isolates(71.1％)were isolated from sputum and respiratory secretions,followed by urine(10.7％)and blood samples(8.1％).B.cepacia isolates were highly susceptible to the five antimicrobial agents recommended in the CLSI M100 document(33rd edition,2023).B.cepacia isolates showed relatively higher resistance rates to meropenem and levofloxacin.However,the resistance rates to ceftazidime,trimethoprim-sulfamethoxazole,and minocycline remained below 8.1％.The percentage of B.cepacia strains resistant to levofloxacin was the highest compared to other antibiotics in any of the three age groups(from 12.4％in the patients＜18 years old to 20.6％in the patients aged 60 years or older).Conclusions B.cepacia is one of the clinically important non-fermenting gram-negative bacteria.Accurate and timely reporting of antimicrobial susceptibility test results and ongoing antimicrobial resistance surveillance are helpful for rational prescription of antimicrobial agents and proper prevention and control of nosocomial infections.

To investigate the distribution of common inhalant and food allergens test results in children in Suzhou by gender, age and disease group, and to analyse the changes in allergen distribution in the different years, to provide theoretical guidance for the diagnosis, treatment and monitoring of children′s allergic diseases in Suzhou City. A retrospective cross-sectional study was conducted to analyze the 2 736 children (1 654 males and 1 082 females) who were diagnosed and tested serum content of specific immunoglobulin E (sIgE) antibodies to inhalant and food allergens in the Children′s Hospital of Soochow University between October 2017 and June 2024. The allergen sIgE positive rates epidemiological characteristics were statistically analyzed by Chi square test by grouping based on different year, gender, age and disease. The results showed that a total of 2 736 children screened for allergens, with an overall positive allergen sIgE rate of 73.06%(1 999/2 736), and the top five allergen sIgE positive rates were Dermatophagoides farinae (40.75%, 1 115/2 736), Dermatophagoides pteronyssinus (38.78%, 1 061/2 736), milk (34.65%, 948/2 736), egg whites (32.68%, 894/2 736) and molds and yeasts mixes (mx2) (24.82%, 679/2 736). The positive rates of food allergen sIgE were higher in the 2017-2019 (60.46%, 370/612) than the 2020-2022 (53.79%, 149/227) and after the 2023-2024 (48.46%, 895/1 847) ( χ2=27.059, P<0.001); The positive rates of inhaled allergen sIgE were lower in the 2017-2019 (40.03%, 245/612) than the 2020-2022 (52.71%, 146/227) and the 2023-2024 (56.04%, 1 035/1 847)( χ2=47.223, P<0.001). The positive rates of inhaled allergen sIgE in males (54.96%, 909/1 654) were higher than those in females (47.78%, 517/1 082) ( χ2=13.497, P<0.001). The total positive rate for the food allergen sIgE was highest at 1-3 years of age (67.55%, 589/872) and then gradually decreased with age ( χ2=194.095, P<0.001); The total positive rate of inhaled allergen sIgE was lowest at the age of less than 1 year (8.33%, 22/206) and then gradually increased with age ( χ2=300.329, P<0.001). The positive rates of food allergen sIgE, in descending order from high to low were asthma (59.40%), atopic dermatitis and eczema (48.10%), other groups (48.02%), allergic rhinitis (45.73%) and urticaria (40.00%); The positive rates of inhaled allergen sIgE were asthma (71.05%), allergic rhinitis (63.57%), atopic dermatitis and eczema (62.17%), urticaria (40.00%) and other groups (49.76%), and the difference between disease subgroups were statistically significant( χ2 were 64.841 and 19.055, P<0.05). In conclusion, the top four allergen sIgE positive rates for children in the Suzhou area were Dermatophagoides farinae, Dermatophagoides pteronyssinus, milk and egg white. Total sIgE positive rates for food allergens decreased progressively in the 2017-2019, 2020-2022 and 2023-2024, and total positive rates for inhalant allergens increased progressively in the 2017-2019, 2020-2022 and 2023-2024. The distribution of allergen positive varies with gender, age and disease.

Objective To summarize the changing prevalence of carbapenem resistance in Enterobacterales based on the data of CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021 for improving antimicrobial treatment in clinical practice.Methods Antimicrobial susceptibility testing was performed using a commercial automated susceptibility testing system according to the unified CHINET protocol.The results were interpreted according to the breakpoints of the Clinical & Laboratory Standards Institute(CLSI)M100 31st ed in 2021.Results Over the seven-year period(2015-2021),the overall prevalence of carbapenem-resistant Enterobacterales(CRE)was 9.43％(62 342/661 235).The prevalence of CRE strains in Klebsiella pneumoniae,Citrobacter freundii,and Enterobacter cloacae was 22.38％,9.73％,and 8.47％,respectively.The prevalence of CRE strains in Escherichia coli was 1.99％.A few CRE strains were also identified in Salmonella and Shigella.The CRE strains were mainly isolated from respiratory specimens(44.23±2.80)％,followed by blood(20.88±3.40)％and urine(18.40±3.45)％.Intensive care units(ICUs)were the major source of the CRE strains(27.43±5.20)％.CRE strains were resistant to all the β-lactam antibiotics tested and most non-β-lactam antimicrobial agents.The CRE strains were relatively susceptible to tigecycline and polymyxins with low resistance rates.Conclusions The prevalence of CRE strains was increasing from 2015 to 2021.CRE strains were highly resistant to most of the antibacterial drugs used in clinical practice.Clinicians should prescribe antimicrobial agents rationally.Hospitals should strengthen antibiotic stewardship in key clinical settings such as ICUs,and take effective infection control measures to curb CRE outbreak and epidemic in hospitals.

Objective To characterize the changing species distribution and antibiotic resistance profiles of respiratory isolates in hospitals participating in the CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021.Methods Commercial automated antimicrobial susceptibility testing systems and disk diffusion method were used to test the susceptibility of respiratory bacterial isolates to antimicrobial agents following the standardized technical protocol established by the CHINET program.Results A total of 589 746 respiratory isolates were collected from 2015 to 2021.Overall,82.6％of the isolates were Gram-negative bacteria and 17.4％were Gram-positive bacteria.The bacterial isolates from outpatients and inpatients accounted for(6.0±0.9)％and(94.0±0.1)％,respectively.The top microorganisms were Klebsiella spp.,Acinetobacter spp.,Pseudomonas aeruginosa,Staphylococcus aureus,Haemophilus spp.,Stenotrophomonas maltophilia,Escherichia coli,and Streptococcus pneumoniae.Each microorganism was isolated from significantly more males than from females(P＜0.05).The overall prevalence of methicillin-resistant S.aureus(MRSA)was 39.9％.The prevalence of penicillin-resistant S.pneumoniae was 1.4％.The prevalence of extended-spectrum β-lactamase(ESBL)-producing E.coli and K.pneumoniae was 67.8％and 41.3％,respectively.The overall prevalence of carbapenem-resistant E.coli,K.pneumoniae,Enterobacter cloacae,Pseudomonas aeruginosa,and Acinetobacter baumannii was 3.7％,20.8％,9.4％,29.8％,and 73.3％,respectively.The prevalence of β-lactamase was 96.1％in Moraxella catarrhalis and 60.0％in Haemophilus influenzae.The H.influenzae isolates from children(＜18 years)showed significantly higher resistance rates to β-lactam antibiotics than the isolates from adults(P＜0.05).Conclusions Gram-negative bacteria are still predominant in respiratory isolates associated with serious antibiotic resistance.Antimicrobial resistance surveillance should be strengthened in clinical practice to support accurate etiological diagnosis and appropriate antimicrobial therapy based on antimicrobial susceptibility testing results.

Retinopathy caused by myopia is the first cause of irreversible blinding eye disease in China.The TCM methods to prevent and control myopia mainly include Chinese materia medica and TCM appropriate techniques,which have the advantages of good efficacy,simple operation,and few adverse reactions.This paper believed that internal and external pathogenic factors act on the brain and eyes,breaking their homeostasis,leading to rhythmic disorders,and imbalance of essence,qi and blood is the main pathogenesis of myopia.Based on the idea of"nature and human in the same rhythm"and"the same treatment for common diseases",targeting the above pathogenesis,the method of"brain-eye synchronization"was proposed to restore the homeostasis of the brain and eyes to prevent and control myopia in children and adolescents,and the treatment rules were to regulate the rhythms of the time,harmonize the qi and blood,nourish the blood to soften the tendons,and replenish the essence and blood,so as to achieve the effect of brain-eye synchronization and the treatment of the spirit and the body together.This article summarized the theoretical basis of"brain-eye synchronization"and its clinical application in traditional Chinese and Western medicine,with a view to providing new ideas for the prevention and control of myopia in children and adolescents.
