OBJECTIVE To investigate a dynamic monitoring of drug consumption （DMDC） model based on the seasonal Mann-Kendall trend test， aiming to provide scientific evidence for the efficient and macroscopic monitoring of drug use. METHODS A monitoring list of key outpatient drugs was established based on the top 20% of drugs ranked by sales volume in the outpatient pharmacy in October 2024. A DMDC model based on the Mann-Kendall trend test was constructed using the monthly usage data of key outpatient drugs from November 2021 to October 2024， aiming to eliminate the impact of seasonal fluctuations and analyze the temporal trends in drug consumption. Taking mucolytic expectorants， triazole derivatives for dermatophytosis， and single-agent hydroxymethylglutaryl coenzyme A （HMG-CoA） reductase inhibitors as examples， the monitoring effectiveness of the DMDC model was demonstrated， and its performance was compared with that achieved by the traditional sequential growth rate ranking method. RESULTS A total of 215 drug varieties were included in the monitoring list， and DMDC models were successfully established for all of them. Among these， 119 showed a significant increasing trend （P＜0.05， S′＞0）. The model successfully monitored the monthly consumption of mucolytic expectorants， triazole derivatives for dermatophytosis， and single- agent HMG-CoA reductase inhibitors. The precision and recall rates of the DMDC model for identifying abnormal drug use were 60.7% and 85.0%， respectively， both significantly higher than those of the sequential growth rate ranking method （8.3% and 15.0%， respectively） （χ2＝20.114， P＜0.001； χ2＝19.600， P＜0.001）. CONCLUSIONS DMDC model based on the seasonal Mann-Kendall trend test can effectively identify long-term trends in drug consumption， eliminate seasonal interference， enhance monitoring accuracy and management efficiency， and is suitable for the dynamic monitoring of drug consumption.

OBJECTIVE To provide empirical basis for promoting the dynamic adjustment of the pharmaceutical care catalogue and the formulation of policies such as hierarchical payment of medical insurance. METHODS A multicenter cross- sectional survey method was adopted to conduct a questionnaire survey among 424 inpatients in 22 tertiary medical institutions in 12 prefecture-level cities of Hubei Province to evaluate their demand for pharmaceutical care， willingness to pay and preference for service forms. Combined with univariate and multivariate Logistic regression analysis， the influencing factors and key factors that affect patients’ willingness to pay for pharmaceutical care were identified. RESULTS Only 39.86% of the patients were aware of pharmaceutical care or pharmacists， and 89.62% of the patients hope to receive pharmaceutical care. Among the 16 types of pharmaceutical care， the patients surveyed had a relatively high recognition rate for guidance on drug usage and dosage， notification of medication precautions， and the identification， prevention and handling of adverse drug reactions. 96.70%， 95.30%， and 94.12% respectively expressed strong approval and approval. The demand for services such as insurance-related policy consultation， popular science on the mechanism of drug action， and assessment of the combined use of traditional Chinese and Western medicines was relatively low， with 61.65%， 68.47%， and 68.47% expressing strong approval and approval respectively. The positive influencing factors of willingness to pay were household monthly income ＞ 5 000 yuan （OR＝1.742）， awareness of pharmaceutical care or pharmacists （OR＝3.620）， and the desire to receive pharmaceutical care （OR＝4.686） （P＜0.05）， while self-rating health as “good” （OR＝0.390） was a negative influencing factor （P＜0.05）. Cardiovascular and cerebrovascular diseases （54.48%） and antihypertensive drugs （45.05%） were the service scenarios that the surveyed patients most hope to be covered. 85.14% of the patients preferred “service when xiaochnye@126.com needed”， with a single service duration of less than 10 minutes being appropriate （84.43%）， and the willingness to pay within 20 yuan being the main type （85.38%）. CONCLUSIONS Based on the characteristics of patients’ needs and payment behaviors， it is suggested that our country could consider establishing a hierarchical payment mechanism for pharmaceutical care， and focus on differentiated design in combination with diseases and medication situations. At the same time， the rights， responsibilities and service standards of resident pharmacists in the links such as medication reorganization and medical order review should be further clarified to comprehensively enhance the clinical value and policy operability of pharmaceutical care.

Immune checkpoint blockade therapy has demonstrated remarkable efficacy in treating various malignancies; however, its clinical application remains challenged by low response rates and immune-related adverse events. Immunoglobulin superfamily member 11 (IGSF11), an inhibitory immune checkpoint molecule, serves as a specific ligand for the V-domain immunoglobulin suppressor of T cell activation (VISTA). Through the IGSF11/VISTA axis, it suppresses T cell function and represents a promising novel target for cancer immunotherapy. IGSF11 is widely expressed across multiple tumor types, though its regulatory mechanisms vary depending on the malignancy. Studies have confirmed that blocking the IGSF11-VISTA interaction or specifically inhibiting IGSF11 exerts antitumor effects. While IGSF11 is closely associated with patient prognosis, its prognostic significance differs among cancer types. This review systematically summarizes the structural characteristics of IGSF11, its regulatory mechanisms, interaction with VISTA, and functional role within the tumor microenvironment.

Objective To explore the predictive value of the preoperative C-reactive protein-albumin-lymphocyte ratio(CALLY index)for short-term prognosis in patients undergoing radical gastrectomy.Methods The clinical data of 228 gastric cancer patients who underwent radical gastrectomy were retrospectively analyzed.Based on follow-up results,patients were divided into the good prognosis group(n=205)and the poor prognosis group(n=23).The differences in clinical characteristics and laboratory test results between the two groups were compared.Cox proportional hazards regression model was used to analyze the impact of CALLY index on poor prognosis in patients.The receiver operating characteristic(ROC)curve was used to determine the clinical value and optimal cutoff value of CALLY index in predicting poor prognosis of patients.Kaplan-Meier method was used to analyze the difference in disease-free survival(DFS)between patients with different CALLY index levels.Results After a follow-up of 3 to 53 months(median follow-up of 36 months),23 patients developed poor prognosis(including 3 deaths and 20 recurrences or metastases).Compared with the good prognosis group,tumors in the poor prognosis group were larger,the proportion of poorly differentiated tumors was higher and white blood cell count(WBC),neutrophil count(NEU),C-reactive protein(CRP)were higher,and lymphocyte(LYM),albumin(ALB),prealbumin,total cholesterol(TC)and CALLY indexl were lower.Multivariate Cox regression analysis showed that the elevated CALLY index(HR=0.306,95%CI:0.102-0.921,P=0.035)was an independent protective factor for poor prognosis,while larger tumors and poorly differentiated tumors were independent risk factors for poor prognosis.ROC curve analysis showed that the area under the curve for predicting poor prognosis in gastric cancer patients undergoing radical gastrectomy was 0.862(95%CI:0.810-0.904),with a sensitivity of 95.65%,specificity of 69.76%,and an optimal cutoff value of 2.21.Kaplan-Meier analysis showed that patients with a CALLY index>2.21 had a longer disease-free survival than those with a CALLY index≤2.21(mean DFS:48 months vs.42 months,Log-rank χ2=4.123,P=0.042).Conclusion The preoperative CALLY index is a simple,effective and easily accessible predictor for predicting short-term prognosis in patients undergoing radical gastrectomy.A high CALLY index indicates a better prognosis of patient.

BACKGROUND:During tissue repair and regeneration,macrophages exhibit multiple activities such as promoting inflammation,anti-inflammation,fibrosis,and wound healing at various stages of tissue damage.The heterogeneity and balanced polarization of macrophages are decisive in organ repair. OBJECTIVE:To explore the research hotspots and development trends in the field of macrophage polarization in tissue repair through visualization analysis methods,as well as the research level of global scientific and clinical workers in this field. METHODS:Using bibliometric analysis methods,this study employed Citespace literature visualization analysis software and VOSviewer tools,retrieving related literature from 2013 to 2023 in the Web of Science Core Collection's Science Citation Index Expanded(SCI-Expanded)and Social Sciences Citation Index Expanded(SSCI-Expanded)databases.The analysis results were presented in a dynamic map format,revealing the main trends and focuses of the research. RESULTS AND CONCLUSION:The number of publications in this field had dramatically increased from 2013 to 2023,with a significant rise starting in 2017.Chinese researchers had the highest number of publications,with 642 papers,while American researchers began focusing on this field early on.Professor Elisseeff Hennifer H had made a substantial contribution to the research in this area.Shanghai Jiao Tong University had produced the most publications.In recent years,keywords such as"hyaluronic acid"and"regulation"had been prevalent.Macrophage polarization research in tissue repair primarily concentrates on its multifunctional regulatory mechanisms,interactions with other cell types,and its behavior under specific pathological conditions.The main research areas include the role of macrophages in wound healing,cardiovascular diseases,chronic inflammation,tumor microenvironments,and regenerative medicine.A deeper understanding of the multifunctionality and polarization mechanisms of macrophages can lead to the development of new therapeutic strategies to enhance tissue repair and regeneration,thereby improving patient treatment outcomes.

BACKGROUND:With the deepening of research on stem cell technology,how to make its accurate homing has become a major problem in clinical application.In addition to the induction of drugs and chemokines,electric fields are also widely used to guide the directional migration of stem cells.They can enhance their migration speed and orientation.OBJECTIVE:To summarize the effect of an electric field on the characteristics of stem cell migration and analyze the possible mechanism of action.METHODS:PubMed and CNKI databases were searched to collect relevant literature up to March 2024,with Chinese and English search terms"stem cells,direct current electric field,pulsed electric field,migration,electric field device,mechanism."Literature that was not available in full text and unrelated to the topic was excluded.RESULTS AND CONCLUSION:A total of 58 articles were included according to the screening requirements,including 15 Chinese articles and 43 English articles.In the literature,the effects of different parameters of the electric field on the migration of adipose-derived mesenchymal stem cells,bone marrow mesenchymal stem cells,neural stem cells,epidermal stem cells,human embryonic stem cells,and human induced pluripotent stem cells and its mechanism were studied in a migration device.(1)As a simple,non-invasive,and stable intervention method,the electric field plays an active role in guiding the directional migration of stem cells.(2)Different types of stem cells had different directions of electrotaxis migration,and the migration speed and directionality of most stem cells increased with the increase of electric field intensity.(3)Different electric field devices have different focuses in observing stem cell migration,and the relevant devices can be selected according to the purpose of the experiment.(4)The mechanism of electrotaxis migration of different stem cells is not completely the same.MAPK pathway,ROCK activation,and PI3K function are involved in the migration process of most stem cells,and other protein complexes and signaling pathways are involved in the regulation of this process.(5)In addition to different electric field parameters,cell senescence and culture environment also affect the results of electrotaxis migration.In summary,as an important signal that affects the migration characteristics of stem cells,the application of electric field combined with other emerging materials has shown certain potential in tissue engineering.It is expected to play a more important role in guiding stem cells to home,promoting bone tissue regeneration and repair,and making greater breakthroughs in the research of the nervous system,autoimmune system,tumors,and other diseases.
