Artificial intelligence-based medical decision-making systems can significantly accelerate decision processes and enhance accuracy.However,challenges persist in achieving personalized care and in the compre-hensive collection of medical data.This paper explores potential solutions to these issues by examining AI ap-plications in diagnostic omics and multi-dimensional data acquisition,providing an overview of current pro-gress and limitations in developing intelligent medical decision systems through these approaches.Additional-ly,the paper also discusses the broad potential for artificial intelligence applications in medical education and their possible contributions to advancing overall decision-making standards in healthcare.

Objective:To investigate the effects of thioredoxin reductase 1 (TXNRD1) on ferroptosis and immune function of dendritic cells (DCs) in septic mice, and to provide a basis for improving the immunosuppression in sepsis caused by wound infection.Methods:This study was an experimental research. Sixty male C57BL/6J mice aged 6-8 weeks were subjected to cecal ligation and puncture (CLP) to establish sepsis models. Ten mice were selected at 0 (immediately), 6, 12, 24, 48, and 72 h after CLP surgery, respectively, according to the random number table method. Mouse splenic DCs were isolated using CD11c-positive magnetic beads. The protein expressions of TXNRD1, and anti-ferroptosis proteins solute carrier family 7 member 11 (SLC7A11), and glutathione peroxidase 4 (GPX4) in the cells were detected by Western blotting, the reduced glutathione (GSH) content in the cells was measured by colorimetric assay, the lipid peroxidation level was assessed via live-cell imaging technology, and the levels of major histocompatibility complex class Ⅱ subtype I-A/I-E and leukocyte differentiation antigens CD80 and CD86 were detected by flow cytometry. Another 100 male C57BL/6J mice aged 6-8 weeks were divided into corn oil+sham injury group, corn oil+CLP group, inhibitor+sham injury group, and inhibitor+CLP group according to the random number table method, with 25 mice in each group. Mice in the two inhibitor groups were intraperitoneally injected with TXNRD1 inhibitor auranofin, while mice in the two corn oil groups were intraperitoneally injected with corn oil. One hour later, mice in the two CLP groups underwent CLP surgery to establish sepsis models, while mice in the two sham injury groups underwent sham surgery. Twenty mice from each group were selected to observe survival within 7 d post-surgery, and the survival rate was calculated. At 24 h post-surgery, mouse splenic DCs from the remaining 5 mice in each group were collected for corresponding assays as above.Results:Compared with those at 0 h after CLP surgery, the protein expressions of TXNRD1, GPX4, and SLC7A11 in mouse cells at 24 h after CLP surgery and the protein expression of TXNRD1 in mouse cells at 48 h after CLP surgery were significantly decreased ( P<0.05), the GSH content in mouse cells was significantly decreased at 24 and 48 h after CLP surgery ( P<0.05). The lipid peroxidation level in mouse cells was low at 0, 6, and 12 h after CLP surgery, slightly lower than that at 72 h after CLP surgery; the lipid peroxidation levels in mouse cells at 24 and 48 h after CLP surgery were significantly higher than those at 0, 6, 12, and 72 h after CLP surgery. Compared with those at 0 h after CLP surgery, the levels of I-A/I-E and CD80 in mouse cells at 6, 12, 24, 48, and 72 h after CLP surgery and the levels of CD86 in mouse cells at 12, 24, and 48 h after CLP surgery were significantly increased ( P<0.05). At 24 h post-surgery, the protein expressions of TXNRD1, SLC7A11, and GPX4 in mouse cells in corn oil+CLP group were significantly lower than those in corn oil+sham injury group ( P<0.05), while the protein expressions of TXNRD1, SLC7A11, and GPX4 in mouse cells in inhibitor+CLP group were significantly lower than those in corn oil+CLP group and inhibitor+sham injury group ( P<0.05). At 24 h post-surgery, the content of GSH in mouse cells in corn oil+CLP group was (239±32) μg/mg, which was significantly lower than (366±59) μg/mg in corn oil +sham injury group ( P<0.05); the content of GSH in mouse cells in inhibitor+CLP group was (134±19) μg/mg, which was significantly lower than (355±31) μg/mg in inhibitor+sham injury group and that in corn oil+CLP group (with both P values <0.05). At 24 h post-surgery, the lipid peroxidation level of mouse cells in inhibitor+CLP group was significantly higher than that in the other three groups ( P<0.05). At 24 h post-surgery, the levels of I-A/I-E, CD80, and CD86 in mouse cells in corn oil+CLP group were significantly higher than those in corn oil+sham injury group ( P<0.05), while the levels of I-A/I-E and CD80 in mouse cells in inhibitor+CLP group were significantly higher than those in inhibitor+sham injury group ( P<0.05) but significantly lower than those in corn oil+CLP group ( P<0.05); the level of CD86 in mouse cells in inhibitor+sham injury group was significantly higher than that in corn oil+sham injury group ( P<0.05). Within 7 d post-surgery, the survival rate of mice in inhibitor+CLP group was significantly lower than that in inhibitor+sham injury group and corn oil+CLP group (with χ2 values of 31.19 and 3.91, respectively, both P values <0.05). Conclusions:In septic mice, the expression of TXNRD1 in DCs is reduced, cell ferroptosis is enhanced, and immune function is weakened. The inhibition of TXNRD1 in DCs will exacerbate cell ferroptosis and immune function suppression, and is closely related to the poor prognosis of sepsis.

Establishing a full-cycle contract management model for comprehensive public hospitals has practical signifi-cance for the development of smart hospitals.The aim is to create a hierarchical and classified contract management system fo-cused on information sharing.The method involves outlining the systematic processes of contract management within the hospital,analyzing common issues from multiple dimensions-such as management processes,level of information technology,and process supervision-and proposing solutions to meet the requirements of modern public smart hospital contract management.Based on in-formation sharing and hierarchical management,this approach offers ideas for refined management in hospitals and promotes the high-quality development of comprehensive medical services in smart hospitals..

Abstract On March 12, 2022, a case with Plasmodium vivax malaria was reported in the First Hospital of Jiaxing City. The case sought healthcare services due to persist, sharp distending pain of the brain and fever on February 25, 2022, and the symptoms showed no improvements following symptomatic treatment. Microscopy identified malaria parasites on March 12, and the case was definitively diagnosed as P. vivax malaria on March 13. The case was discharged from hospital on March 16 and relapsed on June 15. The case was a veteran from the China-Myanmar border, where malaria is highly prevalent, and had no history of travel after returning to Jiaxing City on October 2021. Based on epidemiological history and laboratory tests, the case was diagnosed as a cross-border mosquito-borne imported case of P. vivax malaria. The case was given treatment with mosquito vector isolation, and the case's family members, neighbors and colleagues were all tested negative for malaria parasites. There was no Anopheles sinensis detected in the case' residence; however, Anopheles was detected in the neighboring areas, indicating a risk of re-establishment. Returners from high-risk regions including borders and labor exporters are recommended to be included in malaria surveillance, and the sensitivity of malaria surveillance requires to be maintained and the diagnostic and treatment capability of malaria requires to be improved in medical institutions.

With the goal of practice teaching for laboratory medicine students, we focus on culti-vating students' clinical thinking and scientific thinking through setting up reasonable teaching task and designing the scientific graduation thesis, and try to develop a novel practice teaching mode for laboratory medicine students. Therefore, we do exploration and practice in the following aspects: orientation training, clinical practice, medical ethics education, clinical communication ability, and scientific research design, hoping to improve students' research thinking ability and innovation ability. Through actual operation and graduation thesis writing, we try to help students to establish and improve their clinical thinking ability and innovation ability.

Clinical biochemical test course construction in the new medical model, first of all, requires a combination of subject characteristics of the course, and proceeds with the improvement from the teaching methods and evaluation system. Secondly, we should cultivate students' doctor-patient communication skills and humanities quality in the teaching process. Finally, we should establish the effective clinical biochemical test teaching mode to achieve both teaching and learning.
