OBJECTIVE Identify the incentive and constraint factors of artificial intelligence （AI） application in the pharmaceutical field， and promote the application of AI in the field of pharmacy. METHODS Based on the technology acceptance model （TAM）， technology-organization-environment （TOE） framework， and diffusion of innovation theory （DOI）， a TAM-TOE-DOI integrated framework was constructed through a four-stage research process of “theoretical review → dimension mapping → mechanism integration → proposition development”. Combining the analytical pathways of the above three theories in AI application in pharmacy with the integration mechanisms and core propositions of the TAM-TOE-DOI， literature review and deductive reasoning were employed to systematically identify the incentive and constraint factors of AI application in pharmacy from three levels：micro （TAM）， meso （TOE）， and macro （DOI）， and to propose optimization strategies. RESULTS & CONCLUSIONS At the micro level， the efficiency transformation and quality improvement brought by AI technology were the main incentive factors for perceived usefulness， while technological complexity and algorithmic opacity were the main constraint factors for perceived ease of use. At the meso level， the completeness of technological infrastructure， the strength of top management support and innovation climate， as well as external institutional pressure and competitive driving forces were the core incentive factors， whereas scarcity of organizational resources and talent shortage were the main constraint factors. At the macro level， relative advantage and observability were typical incentive factors， while technological complexity was a typical constraint factor. China’s health administration， medical insurance authorities， and other relevant departments should coordinate efforts at the macro， meso， and micro levels to advance AI application in pharmacy： optimizing human-computer interaction and implementing tiered training programs at the micro level； reinforcing organizational support systems and capacity building at the meso level； dismantling data barriers and building social trust at the macro level. Differentiated implementation pathways should be developed for medical institutions at different tiers.

This article presents a case study of a patient who visited the Geriatric Department of Peking Union Medical College Hospital due to "palpitations, shortness of breath for more than 2 years, limb weakness for 6 months, edema, and nocturnal dyspnea for 2 months". The patient exhibited decreased muscle strength in the limbs and involvement of swallowing and respiratory muscles, alongside complications of heart failure and various arrhythmias which were predominantly atrial. Laboratory tests revealed the presence of multiple autoantibodies and notably anti-mitochondrial antibodies. Following a comprehensive multidisciplinary evaluation, the patient was diagnosed with anti-mitochondrial antibody-associated inflammatory myopathy. Treatment involved a combination of glucocorticoids and immunosuppressants, along with resistance exercises for muscle strength and rehabilitation training for lung function, resulting in significant improvement of clinical symptoms. The case underscores the importance of collaborative multidisciplinary approaches in diagnosing and treating rare diseases in elderly patients, where careful consideration of clinical manifestations and subtle abnormal clinical data can lead to effective interventions.

OBJECTIVE To investigate the horizontal transfer mechanisms and genetic evolutionary characteristics of virulence genes in hypervirulent Klebsiella pneumoniae(HvKP)and resistance genes in carbapenem-resistant K.pneumoniae(CRKP).METHODS The donor strain was a CRKP strain harboring both VIM and KPC resist-ance genes.The positive control was a CRKP strain containing blaIMP-4.The recipient strain was Escherichia coli J53.The horizontal transfer capability of the resistance genes was verified by plasmid conjugation assay.Fifty HvKP strains were collected from the First Affiliated Hospital of Jinan University from 2017 to 2021 and conjuga-ted with the plasmids of five CRKP strains which could mediate the transmission of drug resistance genes.The conjugants were screened by selective medium containing meropenem,and polymerase chain reaction(PCR)was used to detect the resistance and virulence genes in the conjugation-successful strains.The lethality of conjugants was verified by Galleria mellonella larval assays.RESULTS The donor CRKP strain had the ability to mediate re-sistance gene transmission.Its blaKPC gene was successfully transferred to E.coli J53,but the transference of the VIM gene failed.Five CRKP strains with the ability to mediate resistance gene transmission were screened,of which one strain carried both VIM and KPC resistance genes,and the other four strains carried the IMP-4 resist-ance gene.Only one CRKP strain with the blaIMP-4 resistance gene was successfully conjugated with HvKP,carry-ing both virulence genes(aerobactin and RmpA)and the blaIMP-4 resistance gene,with positive wire drawing test result.The Galleria mellonella larvae test showed that the conjugation-successful strain caused the death of all lar-vae within 24 hours.CONCLUSIONS In the hospital environment,CRKP and HvKP can form"superbugs"with both drug resistance and high virulence through plasmid conjugation,posing a severe challenge to clinical an-ti-infection treatment.It is necessary to strengthen the prevention and control of hospital-acquired infections.

Objective:To evaluate the effect of the degree of neuromuscular blockade on the intraoperative surgical conditions and postoperative recovery quality in patients undergoing lumbar interbody fusion.Methods:In this randomized controlled trial, 100 patients of either sex, aged 18-79 yr, with a body mass index of 18.5-35.0 kg/m 2, of American Society of Anesthesiologists Physical Status classification < Ⅳ, scheduled for elective lumbar interbody fusion at the Affiliated Hospital of Xuzhou Medical University from August to October 2024, were allocated into 2 groups ( n=50 each) using stratified randomization based on the number of lumbar segments: deep neuromuscular blockade group (group D) and moderate neuromuscular blockade group (group M). The intraoperative post-tetanic count was maintained at 1 or 2 in group D, and the intraoperative train-of-four was maintained at 1 or 2 in group M. The scores for surgical conditions, duration of operation, blood loss, length of incision, occurrence of severe hypoxemia after extubation, requirement for rescue analgesia in post-anesthesia care unit, 15-item Quality of Recovery scale score and length of stay were recorded. Results:Compared with group M, the scores for surgical conditions were significantly increased, the rate of rescue analgesia in post-anesthesia care unit was decreased, 15-item Quality of Recovery scale scores were increased at 3 days after surgery ( P<0.05), and no significant changes were found in the duration of operation, blood loss, length of incision, incidence of severe hypoxemia after extubation and length of hospital stay in group D ( P>0.05). Conclusions:Compared with moderate neuromuscular blockade, deep neuromuscular blockade can provide better surgical conditions and improve the quality of early postoperative recovery for patients undergoing lumbar interbody fusion.

Objective To explore the effect of Sangxing Zhike Formula in rats with cough vari-ant asthma(CVA)and its possible mechanism based on the cyclic adenosine monophosphate(cAMP)/cystic fibrosis transmembrane conductance regulator(CFTR)pathway.Methods SD rats were randomly divided into control group,model group,dexamethasone group(0.5 mg/kg)and low-,medium-,high-dose Sangxing Zhike Formula groups(9.6,19.2 and 38.4 g/kg)using a ran-dom number table method,with 9 rats in each group.Except for the control group,CVA rat models were established in the other groups.Rats in each group were administered the drug by gavage once a day for 14 consecutive days.The general conditions of rats in each group were observed.Enzyme-linked immunosorbent assay(ELISA)was used to detect the levels of interleukin-1β(IL-1β)and interleukin-18(IL-18)in rat serum.Hematoxylin-eosin(HE)staining and periodic acid-Schiff(PAS)staining were used to observe the pathological changes in rat lung and bronchial tissues,and the acid-base balance of airway surface liquid(ASL)was measured.Western blot and real-time fluorescence quantitative polymerase chain reaction(RT-qPCR)were used to detect the expression levels of pro-tein kinase A(PKA),CFTR protein and their mRNA in lung tissues of rats.Results Compared with the control group,rats in the model group showed listlessness,dull fur,slow weight gain,a significantly expanded area of alveolar septal consolidation,and a large number of inflammatory cell infiltrations around the bronchi.Compared with the model group,rats in each intervention group had better general conditions and reduced inflammatory infiltrations in lung tissues and bronchial lu-mens.Compared with the control group,the serum levels of IL-1 β and IL-18 in the model group were increased,and the pH values of ASL in the model group,low-dose Sangxing Zhike Formula group,medium-dose Sangxing Zhike Formula group,and high-dose Sangxing Zhike Formula group were all decreased,with statistically significant differences(P＜0.05).Compared with the model group,the serum levels of IL-1β and IL-18 in each intervention group were decreased,and the pH values of ASL in the dexamethasone group,medium-dose Sangxing Zhike Formula group,and high-dose Sangxing Zhike Formula group were increased,with statistically significant differences(P＜0.05).Compared with the control group,the expressions of PKA protein and PKA mRNA in the model group,low-dose Sangxing Zhike Formula group,and medium-dose Sangxing Zhike Formula group were all decreased,and the expressions of CFTR protein and CFTR mRNA in the model group and each intervention group were all decreased,with statistically significant differences(P＜0.05).Compared with the model group,the expressions of PKA protein and PKA mRNA in the dexametha-sone group and high-dose Sangxing Zhike Formula group were increased,and the expressions of CFTR protein and CFTR mRNA in the high-dose Sangxing Zhike Formula group were increased,with statistically significant differences(P＜0.05).Conclusion Sangxing Zhike Formula can im-prove the general conditions of CVA rats,regulate the acid-base balance of ASL,reduce airway in-flammatory cell infiltration andairway remodeling,and decrease the levels of inflammatory factors IL-1β and IL-18.Its mechanism may be related to the cAMP/CFTR pathway.

The new cultural construction of high-quality development of public hospitals proposes a patient-oriented ap-proach.People with disabilities,represented by the hearing-impaired community,faces many difficulties in the process of seeking medical care,and their needs have not been adequately addressed.This inadequacy adversely affects the development of harmoni-ous doctor-patient relationships and the patient medical experience.This study takes the deaf assistance outpatient clinic,first es-tablished by Shanghai East Hospital as an example to elaborate the practice of cultural brand construction under the leadership of Party building.Medical social workers,healthcare professionals,and volunteers work together to build a cultural brand through institutional guarantees,detailed care,and the establishment of a full process service system.This is expected to provide refer-ences for the construction of hospital cultural brands..

Objective To evaluate the promoting effect of continuous low-intensity pulsed ultrasound(LIPUS)combined with microbubble(MB)cavitation therapy(hereinafter referred to as ultrasound cavitation therapy)on microcirculatory perfusion in the ischemic hindlimbs of mice,and to explore the non-invasive therapeutic potential of this treatment for limb arterial ischemic injury.Methods A mouse model of left hindlimb ischemia was established,and the mice were randomly assigned to 4 groups(16 mice per group)according to different treatment methods:model group,ultrasound contrast microbubble group(MB group),LIPUS treatment group(LIPUS group),and ultrasound cavitation therapy group(LIPUS+MB group).Mice in the model group were injected with 0.1 mL of normal saline via the tail vein,those in the MB group were injected with 0.1 mL of MB via the tail vein,those in the LIPUS group were treated with LIPUS on the ischemic hindlimb after injection of 0.1 mL of normal saline via the tail vein,and those in the LIPUS+MB group were treated with LIPUS on the ischemic hindlimb after injection of 0.1 mL of MB via the tail vein;each group was injected once a day for a total of 7 d.On the 1st,4th and 7th days after treatment,the microcirculatory perfusion in the ischemic hindlimbs of mice was evaluated using contrast-enhanced ultrasound.The effects of different treatments on promoting microcirculatory perfusion in the ischemic hindlimbs of mice were assessed by combining hematoxylin-eosin(H-E)staining and CD31 immunohistochemical staining of the gastrocnemius muscle tissue in the hindlimbs.Results The left hindlimb ischemia model was successfully constructed,and all model mice showed obvious ischemic microcirculation perfusion disorders with good model stability.After the 7th day of treatment,the LIPUS+MB group showed a increase in microcirculation perfusion in the ischemic hindlimb,with the ratio of microvascular flow on the ischemic to non-ischemic sides higher than that of the LIPUS group([94.33±4.51]%vs[70.33±2.09]%,P＜0.05).H-E staining results showed that the LIPUS+MB group had more newly formed capillaries and myofibroblasts in the gastrocnemius muscle,with better muscle structure repair compared to the LIPUS group,while the model group and MB group showed muscle cell necrosis,disorganized arrangement of muscle bundles,and sparse capillaries.CD31 immunohistochemical analysis further confirmed that ultrasonic cavitation therapy significantly outperformed traditional LIPUS treatment in promoting microcirculation perfusion,microvascular neogenesis,and tissue repair in ischemic skeletal muscles(CD31 relative expression level 5.03±0.33 vs 3.57±0.21,P＜0.01).Conclusion Compared with single LIPUS treatment,continuous ultrasound cavitation therapy has a more significant effect on promoting microcirculation perfusion in the ischemic hindlimb of mice,which provides a new strategy for microcirculatory perfusion disorders in skeletal muscles of limbs caused by peripheral arterial ischemic diseases.

Objective To analyze a case of violations by an occupational medical examination (OME) institution and to explore the key control points for the supervision and management of OME institutions, as well as the core role of quality assessment in this context. Methods An OME institution suspected of illegal activities was used as the study subject. Retrospective analysis was conducted. Clues of suspected violations were identified by an on-site quality assessment. After investigation and verification by the local health authorities, legal action was taken against the institution for its violations. Results During an on-site quality assessment, the Guangdong Province OME quality control expert group discovered that the OME institution violated regulations, including unqualified personnel file, exceeding the scope of services category, issuing false reports, failing to report suspected occupational diseases on time, and failing to notify workers about suspected occupational diseases as required. The evidence was then submitted to the Guangdong Province OME Quality Control Center, which subsequently forwarded the case to local health administration department for filing and investigation. After the investigation, penalties were imposed on the OME institution for its illegal activities. Conclusion The key supervision and inspection points in the quality assessment of OME institutions include personnel file configuration, the quality control management system and its implementation, the quality of OME reports, and information reporting. Quality assessment plays a pivotal role in ensuring the legal and compliant practice of OME institutions, safeguarding the health rights and interests of workers, and enhancing the overall standard of the OME industry.
