Objective To evaluate the application value of artificial intelligence (AI) in the quality control of mammographic images and explore its feasibility for improving image quality. Methods A retrospective analysis was conducted on 500 mammographic images from 125 female patients. These images were acquired in December 2024 at the Department of Radiology, Obstetrics and Gynecology Hospital of Tongji University by two junior technologists with qualification certificate for junior radiologic technologists and ≤ 2 months of independent operation. The reference standard was the evaluation by a panel of senior experts comprising one associate chief radiologist and two intermediate radiologic technologists with over 10 years of experience in mammography. The evaluation was based on nine criteria within an AI quality control system. The correlation and consistency (Kappa test) of the assessment outcomes were compared among the junior technologist group, the AI quality control group, and the panel group. Additionally, the differences in the proportions of high-, medium-, and low-quality images rated by the three groups were analyzed. After one month of AI assistance, 200 images from 50 additional patients acquired by the same two junior technologists in January 2025 were collected. The area under the receiver operating characteristic curve and 95% confidence interval (95%CI) were calculated for the assessment performance of the junior technologist group before and after AI assistance. Differences were compared using the DeLong test. Changes in the disqualification rates for the nine criteria were analyzed. Results In consistency analysis, the AI quality control group showed high consistency with the panel group across multiple key criteria, with Kappa values ranging from 0.41 to 1.00. In contrast, the consistency between the junior technologist group and the panel group was generally low, with Kappa values ranging from 0.13 to 0.49. In comparison of image quality classification, no significant differences were observed in image quality classification between the AI group and the panel group (P>0.05). However, the proportion of images rated as high quality by the junior technologist group was significantly higher, while the proportions rated as medium and low quality were significantly lower, compared to those rated by the panel group (P<0.05). After AI assistance, the area under the receiver operating characteristic curve for the assessment performance of junior technologist group increased significantly from 0.56 (95%CI: 0.51-0.61) to 0.91 (95%CI: 0.87-0.94) (P<0.001). The disqualification rates for skin folds, incomplete inclusion of the pectoralis major muscle, and nipple not in profile decreased significantly. Conclusion AI demonstrates assessment capability comparable to the panel group in mammographic quality control. AI effectively enhances the quality of images acquired by junior technologists through real-time, objective feedback.

ObjectiveTo observe the effects of Hei Xiaoyaosan on the learning and memory abilities of Alzheimer's disease model mice (APP/PS1 mice), and to explore its mechanism through the inflammatory cascade mediated by nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing 3 (NLRP3)/cysteine aspartate-specific protease (Caspase-1)/gasdermin D (GSDMD) signaling pathway. MethodsSPF-grade 4-month-old APP/PS1 mice were randomly divided into the model group, MCC950 group, and Hei Xiaoyaosan high-, medium-, and low-dose groups. C57BL/6J mice were used as the blank group. After 7 days of adaptive feeding, mice in each group were intervened. The Hei Xiaoyaosan high-, medium-, and low-dose groups were given corresponding doses by gavage (25.79, 12.90, 6.45 g·kg-1·d-1), the MCC950 group was intraperitoneally injected with 10 mg·kg-1·2 d-1, and the blank group received the same volume of physiological saline by gavage. After 90 days of intervention, the learning and memory abilities were assessed using the Y maze and Morris water maze tests. The structural changes of hippocampal neurons were observed by hematoxylin-eosin (HE) staining. The expression of amyloid precursor protein (APP) in the hippocampal CA3 region was detected by immunohistochemistry. Enzyme-linked immunosorbent assay (ELISA) was used to measure the levels of interleukin (IL)-10, IL-18, and IL-1β in the hippocampus. Western blot was applied to detect the protein expression of NLRP3, Caspase-1, GSDMD, and GSDMD-N in the hippocampus. Immunofluorescence was used to detect the co-localization of GSDMD-N and ionized calcium-binding adapter molecule-1 (Iba-1) in the hippocampus. Results① In the Y maze test, compared with the blank group, the spontaneous alternation rate of the model group was significantly reduced (P<0.01). Compared with the model group, the spontaneous alternation rate in the Hei Xiaoyaosan high- and low-dose groups was significantly increased (P<0.01). ② In the Morris water maze test, during the 1-4 days of the location navigation test, the escape latency time of mice decreased with the extension of training time. On day 4, compared with the blank group, the model group showed a significantly increased escape latency (P<0.05). Compared with the model group, the MCC950 group and the Hei Xiaoyaosan low-dose group showed significantly reduced escape latency (P<0.05). In the spatial exploration experiment, compared with the blank group, the number of platform crossings in the model group was significantly reduced (P<0.01). Compared with the model group, the Hei Xiaoyaosan low-dose group showed significantly increased platform crossings (P<0.05). ③ HE staining showed that, compared with the blank group, the hippocampal CA3 cells of the model group were damaged, arranged loosely and irregularly, swollen, with unclear boundaries, and the nuclei were pyknotic and deeply stained. MCC950 and all doses of Hei Xiaoyaosan improved the hippocampal CA3 cell damage in APP/PS1 mice to varying degrees. ④ Immunohistochemical results indicated that, compared with the blank group, the expression of APP in the hippocampal CA3 region was significantly increased in the model group (P<0.01). MCC950 and all doses of Hei Xiaoyaosan could reduce the expression of APP in the hippocampal CA3 region of APP/PS1 mice (P<0.01). ⑤ ELISA results showed that the levels of IL-18 and IL-1β in the hippocampus of mice in the model group were significantly increased, and IL-10 levels were significantly reduced (P<0.01). Compared with the model group, the IL-18 levels in the MCC950 group and the Hei Xiaoyaosan medium- and low-dose groups were significantly reduced (P<0.01). IL-1β levels in the hippocampus of the MCC950 group and Hei Xiaoyaosan high-, medium-, and low-dose groups were significantly decreased (P<0.01). The IL-10 levels in the hippocampus of the MCC950 group and the Hei Xiaoyaosan medium- and low-dose groups were increased (P<0.05, P<0.01). ⑥ Western blot results showed that compared with the blank group, the protein levels of NLRP3, Caspase-1, GSDMD, and GSDMD-N in the hippocampus of the model group were significantly elevated (P<0.01). Compared with the model group, the content of NLRP3 and Caspase-1 in the hippocampus of the treated groups was decreased (P<0.05, P<0.01). The content of GSDMD in the hippocampus of the Hei Xiaoyaosan high-, medium-, and low-dose groups was reduced (P<0.05, P<0.01), and the content of GSDMD-N in the hippocampus of the Hei Xiaoyaosan medium- and low-dose groups was decreased (P<0.05, P<0.01). ⑦ Immunofluorescence results showed that, compared with the blank group, the co-expression of GSDMD-N and Iba-1 in the hippocampus of the model group was significantly increased (P<0.01). Compared with the model group, the co-expression of GSDMD-N and Iba-1 in the treated groups was significantly reduced (P<0.01). ConclusionHei Xiaoyaosan may regulate the NLRP3/Caspase-1/GSDMD signaling pathway to affect the release of inflammatory factors, alleviate neuroinflammation,improve hippocampal histopathological changes,and improve learning and memory deficits,thus providing potential therapeutic benefits for Alzheimer's disease.

The exploration and pilot studies of applying blockchain to drug supply chain show great potential in promoting information sharing, collaboration competence among the actors, regulatory efficiency, and etc. In the future, with the help of blockchain, the optimization of the entire supply chain for orphan drugs is expected to be realized. However, there is no such exploration in China at present. This paper systematically sorts out the whole process of supply chain for orphan drugs and the existing problems of the chain. The article concludes that at present, blockchain is mainly used in the " circulation" and " use" of the drug supply chain. It helps to improve the traceability of drugs, to cope with the problem of counterfeit drugs, to enable actors of the drug supply chain to form a collaborative network in optimizing resource allocation, and to improve the operation and supervision efficiency of the supply chain. In the future, the application faces challenges such as high costs in system conversion, lack of personnel awareness, and incomplete supporting systems. Based on the three dimensions of technology, practice, and research, this paper also looks into the future and suggests for the future use of blockchain in the supply chain of orphan drugs by constructing a practice model, the so called DI-GIVE (Digital, Intelligence, Government′s supervision, Innovation, Views of variety, Evaluation-based) hoping to innovate the supply chain of orphan drugs and to ensure the drug use for the patients with rare diseases in China.

Journal of Leukemia & Lymphoma 2025;34(2):125-128
Acute myeloid leukemia (AML) is an aggressive malignant tumor with high heterogeneity. It is characterized by rapid proliferation, dysapoptosis and impaired differentiation of leukemic blast cells. It can develop at any age. The complexity of the etiology, the diversity of mechanisms, and the variability of cytogenetics and genomics hid behind the development and evolution of AML, among which some specific cytogenetic and genomic abnormalities cause the high recurrence rate and drug resistance rate of clinical AML patients. At present, the clinical application of mutated genes has become a hot field in clinical medicine. This paper reviews the role of common mutated genes and molecular targeted therapy in order to provide help for clinical treatment.

OBJECTIVE To summarize the implementation experiences of the China Hospital Association’s Clinical Pharmacist Instructor Training Program Reform, and to evaluate the effectiveness of the reform, thus continuously enhancing the quality and standards of clinical pharmacist instructor training. METHODS The study drew on project evaluation methodologies to summarize the main characteristics of the comprehensive system and new model for clinical pharmacist instructor training established through the reform by literature review. The “learning assessment” and “reaction assessment” were conducted by using Kirkpatrick’s four-level model of evaluation in order to evaluate the effectiveness of the clinical pharmacist instructor training reform through statistically processing and analyzing the performance data and teaching evaluation data of the instructor participants. Based on problem and trend analysis, the future development directions were anticipated for the reform of clinical pharmacist instructor training. RESULTS & CONCLUSIONS The latest round of clinical pharmacist instructor training reform initiated by the Chinese Hospital Association had initially established a four-pronged training system encompassing “recruitment, training, assessment, and management”. It had also forged a training 。 model “oriented towards enhancing clinical teaching competency, with practical learning and skill-based assessment conducted on clinical teaching sites as its core”. Following a period of over three years of gradual reform, the new training system and model became increasingly mature. In both 2023 and 2024, the participants achieved relatively high average total scores in their initial completion assessments [with scores of (84.05± 5.83) and (85.82±4.35) points, respectively]. They also reported a strong sense of gain from the training reform [with self- perceived gain scores of (4.80±0.44) and (4.85±0.39) points, respectively]. The operation and implementation effects of the reform were generally satisfactory. In the future, clinical pharmacist instructor training reforms should continue to address the issues remaining from the current phase, while aligning with global trends in pharmacy education and industry development. Additionally, sustained exploration and practice will be carried out around the core objective of “enhancing clinical teaching competence”.
