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.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

OBJECTIVE: To investigate the current status of long-term quality of life in patients with severe acute pancreatitis (SAP) who have been cured and discharged, and to analyze the influencing factors affecting long-term quality of life in SAP cured patients after discharge. METHODS: A retrospective collection was conducted. Patients who were received standardized treatment before being cured and discharged from the hospital admitted to the first department of critical care medcine of the Second Affiliated Hospital of Anhui Medical University from January 2017 to December 2023 were enrolled. According to the 36-item short form health survey scale (SF-36) score, patients were divided into high score group (high quality of life, the top 50% of patients with total SF-36 score) and low score group (low quality of life, the bottom 50% of patients with total SF-36 score). The gender, age, history of hypertension and diabetes, etiology of pancreatitis, acute physiology and chronic health evaluation II (APACHE II), sequential organ failure assessment (SOFA), CT severity index (CTSI), laboratory indicators such as C-reactive protein (CRP), procalcitonin (PCT), blood glucose, and triglycerides upon admission, use of vasoactive drugs, non-invasive/high-flow ventilation, invasive ventilation, retroperitoneal puncture and drainage, open pancreatic surgery treatment and secondary infection during hospitalization were collected, as well as the retention of abdominal drainage tubes at discharge from hospital. Distribute follow-up questionnaires or telephone follow-up surveys through WeChat and Question Star programs to investigate the pancreatic secretion function, chronic abdominal pain, and recurrence of pancreatitis of patients after discharge. Multivariable Logistic regression was used to analyze the relevant factors affecting the long-term quality of life of cured patients with SAP. RESULTS: A total of 86 patients were ultimately enrolled. There were 43 patients in both the high and low score groups. Among 86 patients, 20 experienced acute pancreatitis recurrence, with a recurrence rate of 23.26%. Twenty-two (25.58%) experienced chronic abdominal pain after discharge, and 5 patients (5.81%) needed medication to relieve pain. Thirty-three patients (38.37%) had pancreatic exocrine dysfunction after discharge, characterized by abdominal distension, constipation or diarrhea. Twenty-two patients (25.58%) suffered from pancreatic endocrine dysfunction, and were diagnosed with diabetes. Univariate analysis showed that compared with the high score group, the low score group had more patients with hypertension, initial renal dysfunction, initial severe metabolic acidosis, initial serum calcium < 2.0 mmol/L, blood glucose > 11.1 mmol/L and cultured Gram positive bacteria (from blood/body fluid/pancreatic necrotic tissue) during treatment (48.84% vs. 16.28%, 60.47% vs. 32.56%, 18.60% vs. 4.65%, 88.37% vs. 62.79%, 55.81% vs. 30.23%, 34.88% vs. 13.95%), had higher CTSI score (6.60±1.61 vs. 5.77±1.32), lower hemoglobin level at discharge (g/L: 102.30±18.78 vs. 110.72±16.68), and a lower proportion of etiological interventions after discharge (34.88% vs. 67.44%), the differences were statistically significant (all P < 0.05). Multivariate Logistic regression analysis showed that hypertension [odds ratio (OR) = 4.814, 95% confidence interval (95%CI) was 1.196-19.378], initial serum calcium < 2.0 mmol/L (OR = 6.688, 95%CI was 1.321-33.873) and initial blood glucose > 11.1 mmol/L (OR = 6.473, 95%CI was 1.399-29.950) were risk factors for long-term quality of life in cured SAP patients (all P < 0.05), while post discharge prophylactic intervention was a protective factor for long-term quality of life (OR = 0.092, 95%CI was 0.020-0.425, P < 0.01). CONCLUSIONS Cured SAP patients have varying degrees of impaired secretion function and the possibility of recurrence of acute pancreatitis. Hypertension, initial serum calcium < 2.0 mmol/L and blood glucose > 11.1 mmol/L are independent influencing factors for low long-term quality of life in cured SAP patients. Prevention and intervention targeting the etiology of pancreatitis after discharge can improve the long-term quality of life of cured SAP patients.

To address the challenges faced by current brain midline segmentation techniques, such as insufficient accuracy and poor segmentation continuity, this paper proposes a deep learning network model based on a two-stage framework. On the first stage of the model, prior knowledge of the feature consistency of adjacent brain midline slices under normal and pathological conditions is utilized. Associated midline slices are selected through slice similarity analysis, and a novel feature weighting strategy is adopted to collaboratively fuse the overall change characteristics and spatial information of these associated slices, thereby enhancing the feature representation of the brain midline in the intracranial region. On the second stage, the optimal path search strategy for the brain midline is employed based on the network output probability map, which effectively addresses the problem of discontinuous midline segmentation. The method proposed in this paper achieved satisfactory results on the CQ500 dataset provided by the Center for Advanced Research in Imaging, Neurosciences and Genomics, New Delhi, India. The Dice similarity coefficient (DSC), Hausdorff distance (HD), average symmetric surface distance (ASSD), and normalized surface Dice (NSD) were 67.38 ± 10.49, 24.22 ± 24.84, 1.33 ± 1.83, and 0.82 ± 0.09, respectively. The experimental results demonstrate that the proposed method can fully utilize the prior knowledge of medical images to effectively achieve accurate segmentation of the brain midline, providing valuable assistance for subsequent identification of the brain midline by clinicians.

ObjectiveTo observe the clinical effectiveness and safety of Xuandi Ziyin Mixture （玄地滋阴合剂） for central precocious puberty （CPP） in girls with syndrome of yin deficiency and fire exuberance， and to analyse the effect of body mass index （BMI） on the effectiveness. MethodsA total of 236 girls with CPP of yin deficiency and fire exuberance syndrome were included， and all of them were given Xuandi Ziyin Mixture， 30 ml each time， twice a day， for a total treatment period of 6 months. Before and after treatment， children's weight， height and bone age were measured， BMI and BMI Z-score （BMI Z） and the difference between bone age and actual age were calculated； ultrasound was used to detect uterine and ovarian sizes， and to calculate uterine volume （V_uterus）， bilateral ovarian volume （V_{left ovary}， V_{right ovary}）， and bilateral maximal follicle diameters （r_{left follicle} and r_{right follicle}）； and serum sex hormones were measured， including follicle-stimulating hormone （FSH）， luteinising hormone （LH）， prolactin （PRL）， estradiol （E₂）， and testosterone （T）， and were scored for traditional Chinese medicine （TCM） syndrome. Multiple linear regression was used to analyse the influence factors of the difference between bone age and actual age， and changes in uterine volume. The children were divided into the normal weight group and the overweight/obesity group according to baseline BMI， and the bone age， the difference between bone age and actual age， V_uterus and BMI Z scores before and after treatment were compared between the two groups. ResultsFinally， 199 children entered the statistical analysis. Compared with pre-treatment， the bone age， BMI and BMI Z scores of the children increased after treatment， and the difference between bone age and actual age， TCM syndrome scores， V_uterus， V_{left ovary}， V_{right ovary}， r_{left follicle} and r_{right follicle} decreased； and the levels of serum FSH， LH， E₂， and T significantly decreased （P＜0.05 or P＜0.01）. The difference between bone age and actual age was negatively correlated with LH and V_uterus （P＜0.05）， and changes in uterine volume were positively correlated with LH （P＜0.01）. Comparing between the groups before and after treatment， the bone age， difference between bone age and actual age， and BMI Z scores of children in the normal weight group （100 cases） were significantly smaller than those in the overweight/obesity group （99 cases） （P＜0.01）. Compared with pre-treatment， the bone age of the children in both groups increased， but the difference between bone age and actual age and V_uterus were significantly smaller （P＜0.01）. Further comparison of Δ bone age and actual age difference and ΔV_uterus （Δ = post-treatment value - pre-treatment value） between the two groups showed no statistically significant difference （P＞0.05）. ConclusionsXuandi Ziyin Mixture can reduce bone age， sex hormone level， ovary and uterus size， and improve clinical symptoms in girls with yin deficiency and fire exuberance syndrome of CPP. It is also effective in overweight/obese children， and the inhibitory effect on bone age in girls with CPP is not affected by BMI， with good safety.

Objective To investigate the clinical characteristics and molecular epidemiology of carbapenem-resistant Klebsiella pneumoniae(CRKP)isolated from patients with bloodstream infections in a large tertiary-care general hospital in Southwest China.Methods A total of 131 strains of non-repeating CRKP were collected from the blood cultures of patients who had bloodstream infections in 2015-2019.The strains were identified by VITEK-2,a fully automated microbial analyzer,and matrix-assisted laser desorption ionization-time of flight(MALDI-TOF)mass spectrometry.The minimum inhibitory concentration(MIC)was determined by microbroth dilution method.The common carbapenemase resistant genes and virulence factors were identified by PCR.Homology analysis was performed by multilocus sequencing typing.Whole genome sequencing was performed to analyze the genomic characteristics of CRKP without carbapenemase.Results The 131 strains of CRKP showed resistance to common antibiotics,except for polymyxin B(1.6%resistance rate)and tigacycline(8.0%resistance rate).A total of 105(80.2%)CRKP strains carried the Klebsiella pneumoniae carbapenemase(KPC)resistance gene,15(11.4%)strains carried the New Delhi Metallo-β-lactamase(NDM)gene,and 4(3.1%)isolates carried both KPC and NDM genes.Sequence typing(ST)11(74.0%)was the dominant sequence type.High detection rates for mrkD(96.2%),fimH(98.5%),entB(100%),and other virulence genes were reported.One hypervirulent CRKP strain was detected.The seven strains of CRKP that did not produce carbapenemase were shown to carry ESBL or AmpC genes and had anomalies in membrane porins OMPK35 and OMPK36,according to whole genome sequencing.Conclusion In a large-scale tertiary-care general hospital,CRKP mainly carries the KPC gene,has a high drug resistance rate to a variety of antibiotics,and possesses multiple virulence genes.Attention should be paid to CRKP strains with high virulence.
