The widespread application of medical artificial intelligence （AI） has brought technological breakthroughs to traditional diagnosis and treatment and has also altered the traditional doctor-patient interaction mode and formed a new doctor-patient relationship of “doctor-medical AI-patient” which faces a series of challenges. The intervention of AI may form a new “paternalistic style，” affecting the shared decision-making model. When its recommendations lack explanation， it may lead to clinical decision-making paralysis and affect the doctor-patient trust relationships. There may be confusion between the roles and responsibilities of AI and doctors in the process of medical practice， affecting the establishment of an emotionally responsible doctor-patient relationship. Through an in-depth analysis of the impact and causes of medical AI on the doctor-patient relationships， this paper proposed that a collaborative mechanism should be established between AI and professional doctors to complement each other， clarifying the auxiliary status of AI， reinforcing the dominant role of doctors， enhancing the regulatory mechanism， and dynamically improved the doctor-patient relationships to promote the healthy and orderly development of smart healthcare.

[Objective] To explore the strategy of blood management in patients with massive transfusion in the frigid plateau region. [Methods] The treatment process of a patient with liver rupture in the frigid plateau region was analyzed, and the blood management strategy of the frigid plateau region was discussed in combination with the difficulties of blood transfusion and literature review. [Results] The preoperative complete blood count (CBC) test results of the patient were as follows: RBC 3.14×10¹²/L, Hb 10⁶ g/L, HCT 30.40%, PLT 115.00×10⁹/L; coagulation function: PT 18.9 s, FiB 1.31 g/L, DD > 6 μg/mL, FDP 25.86 μg/mL; ultrasound examination and imaging manifestations suggested liver contusion and laceration / intraparenchymal hematoma, splenic contusion and laceration, and massive blood accumulation in the abdominal cavity; it was estimated that the patient's blood loss was ≥ 2 000 mL, and massive blood transfusion was required during the operation; red blood cell components were timely transfused during the operation, and the blood component transfusion was guided according to the patient's CBC and coagulation function test results, providing strong support and guarantee for the successful treatment of the patient. The patient recovered well after the operation, and the CBC test results were as follows: RBC 4.32×10¹²/L, Hb 144 g/L, HCT 39.50%, PLT 329.00×10⁹/L; coagulation function: APTT 29.3 s, PT 12.1 s, FiB 2.728 g/L, DD>6 μg/mL, FDP 25.86 μg/mL. The patient was discharged after 20 days, and regular follow-up reexamination showed no abnormal results. [Conclusion] Individualized blood management strategy should comprehensively consider the patient’s clinical symptoms, the degree of hemoglobin decline, dynamic coagulation test results and existing treatment conditions. Efficient and reasonable patient blood management strategies can effectively improve the clinical outcomes of massive transfusion patients in the frigid plateau region.

OBJECTIVE To investigate the ameliorating effect and mechanism of the effective substance groups from Artemisia ordosica（Abbreviated as HSH） on rheumatoid arthritis （RA） based on cluster of differentiation 4/lymphocyte cell-specific protein- tyrosine kinase/zeta-chain-associated protein kinase of 70 kDa/interleukin-17（CD4/LCK/ZAP70/IL-17） signaling pathway. METHODS The rats were divided into normal group， model group， HSH low-dose， medium-dose and high-dose groups （2.7， 10.8， 21.6 mg/kg） and positive control group （Tripterygium glycosides tablet， 6.3 mg/kg）， with 10 rats in each group. Except for normal group， RA rat model was induced by complete Freund’s adjuvant in other groups. After modeling， each group was given relevant medicine or normal saline intragastrically， once a day， for 28 consecutive days. The changes in ankle joint swelling and arthritis index in rats were determined； the pathological changes of ankle joint tissue were observed； the levels of inflammatory factors [IL-1β， IL-21， IL-17A， IL-2， interferon-γ （IFN-γ） and IL-6] in serum and joint fluid of rats were determined； the levels of Th1， Th17 and Treg cells in the whole blood and spleen of rats were detected； protein and mRNA expressions of LCK， proto-oncogene tyrosine-protein kinase Fyn （Fyn）， ZAP70， CD45， RAR-related orphan receptor γt （RORγt）， and forkhead box protein 3 （Foxp3） in ankle synovial tissue were determined. RESULTS Compared with normal group， the changes in ankle joint swelling， arthritis index， the levels of IL-1β， IL-21， IL-17A， IL-2， IFN-γ and IL-6 in serum and joint fluid， the levels of Th1， Th17 cells and Th17/Treg value in whole blood and spleen， and the protein and mRNA expression levels of LCK， Fyn， ZAP70， CD45， and RORγt in ankle joint synovium were all significantly increased/elevated （P＜0.05）. The level of Treg cells in the spleen， as well as the protein and mRNA expression levels of Foxp3 in the ankle joint synovium were significantly decreased （P＜0.05）. Compared with model group， most of the above-mentioned indicators were significantly reversed in the positive control group and all dose groups of HSH （P＜0.05）. The degree of pathological changes in ankle joint tissues was markedly improved， and inflammation was alleviated. CONCLUSIONS HSH can regulate the cascade reactions in the CD4/LCK/ZAP70/IL-17 pathway within the T-cell receptor signaling pathway， thereby modulating the Th17/Treg balance. This leads to the suppression of inflammatory responses and the alleviation of synovial tissue damage in rats with RA.

Antimicrobial resistance (AMR) has emerged as a major global public health challenge, with traditional prevention and control methods exhibiting significant limitations in detection efficiency, data processing, and clinical decision-making. Leveraging its robust capabilities in data analysis and pattern recognition, artificial intelligence (AI) technology has been widely applied across multiple critical aspects of AMR containment. Current evidence demonstrates that AI technologies can significantly enhance the efficiency of resistancediagnosis, optimize personalized treatment strategies, and improve real-time monitoring of resistant pathogen transmission. Despite persistent challenges such as data heterogeneity, model interpretability, and ethical compliance in practical applications, AI holds immense promise in supporting precision infection management and addressing the growing crisis of antimicrobial resistance.This article systematically reviews the clinical applications of AI in AMR prevention and control, including resistance detection and prediction based on mass spectrometry and genomic data, the use of clinical decision support systems in anti-infective therapy, as well as the role of AI in epidemiological surveillance, pathogen tracking, early warning systems, and novel antimicrobial drug discovery aiming to provide reference for clinical practice.

BACKGROUND: Endoscopic sphincterotomy (EST) is widely used to treat common bile duct stones (CBDS); however, long-term studies have revealed the increasing incidence of recurrent CBDS after EST. Loss of sphincter of Oddi function after EST was the main cause of recurrent CBDS. Reparation of the sphincter of Oddi is therefore crucial. This study aims to investigate the effectiveness and safety of endoclip papilloplasty (ECPP) for repairing the sphincter of Oddi and elucidate its mechanism. METHODS: Eight healthy Bama minipigs were randomly divided into the EST group and the ECPP group at a 1:1 ratio, and bile samples were collected before endoscopy and 6 months later. All minipigs underwent transabdominal biliary ultrasonography for the diagnosis of cholelithiasis 6 months after endoscopy. The biliary microbiota composition and alpha and beta diversity were analyzed by 16S ribosomal RNA gene sequencing. Differential metabolites were analyzed by bile acid metabolomics to explore the predictive indicators of cholelithiasis. RESULTS: Three minipigs were diagnosed with cholelithiasis in the EST group, while none in the ECPP group showed cholelithiasis. The biliary Firmicutes/Bacteroidota (F/B) ratio was increased after EST and decreased after ECPP. The Chao1 and observed species index significantly decreased 6 months after EST ( P  = 0.017 and 0.018, respectively); however, the biliary α-diversity was similar before and 6 months after ECPP. The β-diversity significantly differed in the EST group before and 6 months after EST, as well as in the ECPP group before and 6 months after ECPP (analysis of similarities [ANOSIM]: R  = 0.917, P  = 0.040; R  = 0.740, P  = 0.035; respectively). Glycolithocholic acid (GLCA) and taurolithocholic acid (TLCA) accumulated in bile 6 months after EST. CONCLUSIONS ECPP has less impact on the biliary microenvironment than EST and prevents duodenobiliary reflux by repairing the sphincter of Oddi. The bile levels of GLCA and TLCA may be used to predict the risk of cholelithiasis.

This paper examines the integration of Confucian ethics into modern nursing practice and its implications,offering a review of the book Contemporary Medicine and Confucian Thought by Professor Fan Ruiping.The book addresses six key topics:medical decision-making,healthcare systems,medical technology,organ transplantation,mental health,and elderly care.It highlights the conflicts between individual autonomy emphasized in Western ethics and the family-centered approach of Confucianism,especially in clinical decision-making.Through case studies and ethical discussions,the book suggests integrating Confucian ethics with modern medical systems to balance personal and familial interests in patient care.From the perspective of nursing,this review emphasizes the relevance of Confucian principles such as family-centered care,the integration of moral emotions like benevolence and respect,and the importance of developing culturally appropriate ethical models for clinical decision-making.It calls for a paradigm shift in nursing education and practice toward a family-centered approach,promoting harmony between individual and collective needs.Additionally,it discusses the challenges and opportunities for integrating Confucian ethics into cross-cultural nursing in a globalized healthcare environment.The review concludes that Confucian ethics can provide valuable insights into the development of more humanistic and ethically sound nursing practices,particularly in the context of a rapidly evolving medical landscape.

Objective:To explore the current dilemmas in the survival and development of elderly-friendly medical institutions from the dual perspectives of medical staff and elderly patients,to optimize the construction of elderly-friendly medical institutions,to create a friendly,safe,and comfortable medical environment,provide comprehensive,continuous,and caring medical services for the elderly.Methods:Based on the questionnaire survey method,the existing dilemmas and development paths of elderly-friendly medical institutions from multiple dimensions were explored,including culture,management,service,and environment.Results:Quantitative research showed that elderly patients satisfaction with the friendly culture of the medical,but 28(21.1%)still thought that the medical staff did not communicate with them adequately,and 73(54.9%)thought that the institutions lacked health education and guidance for them.In the evaluation of the medical environment,the dissatisfaction of elderly patients was manifested as inadequate transportation facilities(33 visits),lack of barrier-free facilities(29 visits),and unclear medical guidance(25 visits).The results of the chi-square test showed that there was a statistically significant difference in waiting time for medical services among elderly patients based on gender(P<0.05),and women were more patient.There were statistically significant differences in the level of service convenience and satisfaction with geriatric syndrome assessment among elderly patients of different age groups(P<0.05).Qualitative research found that there were problems in the management of elderly-friendly medical institutions,such as cumbersome referral processes,low enthusiasm of medical staff,insufficient elderly professionals,and a lack of performance evaluation and training systems.Conclusion:To solve the existing difficulties of elderly-friendly medical institutions,it should start with paths of strengthening the training of medical staff,improving the hospital management system,upgrading the level of service specialization,and improving the aging-appropriate environment,to enhance the sense of accessibility of medical care for elderly patients and improve their quality of life.

Proteus mirabilis is a gram-negative rod-shaped bacterium that can cause urinary tract infections, bloodstream infections and gastrointestinal infections. Urinary tract infections caused by Proteus mirabilis are hard to be treated and pose a serious public health problem. With the use of antimicrobial drugs for clinical treatment, the resistance rates of Proteus mirabilis to β-lactams and quinolones increase. Besides the unregulated use of antimicrobial drugs contributes to the emergence of multidrug-resistant Proteus mirabilis and carbapenem-resistant Proteus mirabilis. In this review, we will discuss Proteus mirabilis-related clinical infections, and the epidemiological characteristics and β-lactam resistance mechanism, hoping to provide ideas for the treatment and prevention of Proteus mirabilis infections in the future.

Objective:To evaluate the curative effect of Sun's procedure using sutureless artificial blood vessel replacement technique on acute type A aortic dissection.Methods:Retrospective analysis was performed on 40 patients with acute type A aortic dissection who underwent Sun's procedure in The First People's Hospital of Nanning from May 2019 to April 2023. According to the surgical method, the patients were divided into sutureless group (20 cases) and traditional group (20 cases).The time of stopping circulation, cardiopulmonary bypass, recovery time, intubation time, blood loss 12 h after operation, cerebral infarction and acute renal failure were compared between the two groups.Patients older than 70 years, patients with preoperative malperfusion syndrome, or patients who did not undergo Sun's procedure were excluded.Results:The time of stopping circulation[( 13.6±3.3)min vs. ( 28.2±5.6)min, P<0.001] and the time of cardiopulmonary bypass[(116.0±34.8)min vs.(219.1±46.3 )min, P<0.001]and blood loss at 12 h after operation[( 474.5±301.0)ml vs. (422.7±389.8)ml, P<0.001] in the sutureless group were significantly lower than those in the traditional group.All patients survived and were discharged from hospital. There were no significant differences in recovery time, intubation time, cerebral infarction and acute renal failure between the two groups. Conclusion:Sutureless artificial blood vessel replacement technique can significantly shorten the time of stopping circulation and cardiopulmonary bypass, effectively protect the function of the whole body organs, and reduce the occurrence of postoperative complications.Moreover, it is easy to carry out in primary hospitals, and it is a safe and effective new surgical strategy for treating acute type A aortic dissection with Sun's surgery.
