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 explore the correlation between drug consumption index and diagnosis related groups （DRG） overspending cases， and provide a basis for hospitals to optimize the cost structure and strengthen the refined management. METHODS Based on the data of DRG patients enrolled in a third-grade class A hospital from September to November 2023， the multivariate Logistic regression model and restricted cubic spline （RCS） model were used to analyze the correlation of drug consumption index with DRG overspending cases and its threshold effect， respectively. At the same time， rational drug use evaluation was conducted based on the drug consumption index， precise cost control and management were carried out， and the changes in the main pharmaceutical indicators of the whole hospital were analyzed before control （January-June 2023） and after control （January-June 2024）. RESULTS The results of multivariate Logistic regression analysis showed that long hospitalization days， high drug consumption index， transfer to other departments and combined diabetes mellitus were the risk factors for DRG overspending （P＜0.05）. The results of the RCS model showed that the drug consumption index had a non-linear relationship with DRG overspending. When the drug consumption index was ≥0.64， the drug consumption index was positively correlated with the risk of DRG overspending（P＜0.05）. Compared with the same period before the control， medical cost per time， drug cost per time and drug consumption index decreased significantly after the control （P＜0.01）. CONCLUSIONS The drug consumption index is a risk factor for DRG overruns， there is a non-linear relationship and threshold effect between it and DRG overruns. Each hospital can set a reasonable threshold and implement dynamic monitoring and intervention by comprehensively considering the actual drug usage， disease spectrum characteristics， and cost control targets， as well as factors such as medical quality， patient needs， and the payment capacity of medical insurance， which can effectively achieve precise control over drug usage.

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 analyze the current situation and influencing factors of work-related musculoskeletal disorders (WMSDs) among scientific researchers in a computer workstation of a high-tech aerospace enterprise, and to provide data support for the improvement of occupational health management policies in this type of enterprise.Methods:From March to April 2023, using convenient sampling method, 1398 scientific researchers using computer workstations in an aerospace high-tech enterprise in Beijing were selected as the research subjects. The incidence of WMSDs in various parts of the body was investigated by using the Musculoskeletal Disorders Questionnaire, and the influencing factors of WMSDs in neck, lower back, shoulder and upper back were analyzed by logistic regression.Results:The total incidence of WMSDs was 55.4% (774/1398) in the scientific researchers who used computer workstations. The top 4 body parts in WMSDs incidence were neck (24.3%, 340/1398), lower back (20.4%, 285/1398), shoulder (18.7%, 262/1398), upper back (12.7%, 177/1398). The results of multivariate logistic regression analysis showed that feeling slightly tired and tired after work, setting a rest/break time of 10 to 15 min before the next continuous job, and operating computer for 2 to 4 hours and >4 hours were the influencing factors for the occurrence of neck WMSDs ( OR=3.08, 1.90, 0.60, 2.00, 1.49, P<0.05). Female, 5-<10 years of working experience, feeling slightly tired, tired and very tired after work, operating computer for 6-<8 hours and 8-10 hours a day were all the influencing factors for the occurrence of WMSDs in the lower back ( OR=1.82, 0.64, 2.95, 1.80, 1.61, 1.82, 1.73, P<0.05). Female, feeling slightly tired and tired after work were the influencing factors of shoulder WMSDs occurrence ( OR=2.42, 2.09, 2.00, P<0.05). Female, 5-<10 years, 10-15 years of working age, 1-3 times of physical exercise/quarter, feeling slightly tired, tired and very tired after work were the influencing factors for the occurrence of upper back WMSDs ( OR=2.76, 2.19, 2.78, 0.48, 4.20, 2.66, 2.19, P<0.05) . Conclusion:The incidence of WMSDs among scientific researchers in computer workstations of aerospace high-tech enterprises is high, which is closely related to individual characteristics and workstation usage characteristics. Measures should be taken to prevent and improve the WMSDs status of scientific researchers.
