OBJECTIVE To construct ensemble learning models for predicting high-use days of budesonide based on meteorological factors, thereby providing reference for hospital pharmacy management. METHODS Meteorological data for 2024 and outpatient budesonide usage data from the jurisdiction of Sanming Hospital of Integrated Traditional Chinese and Western Medicine were collected. High-use days were defined as the 75th percentile of outpatient budesonide usage, and a corresponding dataset was established. The prediction task was formulated as a classification problem, and three ensemble learning models were developed: Random Forest, Extreme Gradient Boosting (XGBoost), and Histogram-based Gradient Boosting Classifier. Model performance was evaluated using accuracy, precision, recall, F1-score, and log-loss. Model interpretability was analyzed using Shapley Additive Explanations (SHAP). RESULTS The Histogram-based Gradient Boosting Classifier achieved the best performance (accuracy=0.75, F1-score=0.48), followed by XGBoost (accuracy=0.74, F1-score=0.43) and Random Forest (accuracy=0.72, F1-score=0.22). SHAP results suggested that the prediction results of the last two models have the highest correction. CONCLUSIONS Ensemble learning models can effectively predict high-use days of budesonide, with the Histogram- based Gradient Boosting Classifier demonstrating the best predictive performance. Low temperature, high humidity, and low atmospheric pressure show significant positive impacts on the prediction of daily budesonide usage.

AIM: To investigate the effects of agkis-trodon halys venom anti-tumor component (AHVAC-) on the biological behavior of gastric cancer MKN-28 cells. METHODS: Gastric cancer MKN-28 cells were treated with the experimental concentrations (5, 10, 15 μg/mL) of AHAVC- for 24 h. Cell proliferation and toxicity assay (cell counting kit-8, CCK-8) was used to detect the inhibition rates of the cells in different concentrations of AHVAC-. The migration ability of the cells was evaluated by wound-healing and Transwell assay. The apoptosis were observed by laser confocal microscopy with annexin V-mCherry/DAPI double staining, and the apoptosis rates were analyzed by flow cytometry with annexin V-FITC/PI double fluorescence staining. The protein level of Caspease-3 was determined by Western blot. RESULTS: Compared with normal control group, the results of AHVAC- concentration groups showed that with the increase of AHVAC- concentration, the proliferative activity of MN-28 cells decreased gradually (P<0.01), the cell migration ability decreased gradually (P<0.01), and the cell apoptosis rate increased (P<0.05). The expression of apoptosis-related protein Caspease-3 was up-regulated (P<0.01). CONCLUSION: AHVAC- inhibits proliferation and migration of gastric cancer MSN-28 cells and induces apoptosis.

OBJECTIVE
To explore the application of HL60-pNL3.2 reporter gene assay in pyrogen detection of live attenuated varicella vaccine, inactivated influenza vaccine and lyophilized live attenuated hepatitis A vaccine.
METHODS
According to the publication draft named as "in vitro pyrogen test(reporter gene assay)" in Chinese Pharmacopoeia, maximum valid dilution(MVD) of three kinds of vaccines was calculated, and the interference test was conducted to explore whether these vaccines interfere with the pyrogen determination. According to the general rule 9101 from Chinese Pharmacopoeia 2020, the assay in the pyrogen detection of the three vaccines was validated, using the methods to determine the pyrogen content of three vaccines.
RESULTS
The MVD of live attenuated varicella vaccine, inactivated influenza vaccine and lyophilized live attenuated hepatitis A vaccine respectively were 1 000, 200 and 1 000 times. The recovery rates of endotoxin(LPS) in the three kinds of vaccine were between 52.5% and 110.1%. The methodological validation results showed that the method could be used for the determination of pyrogens in three vaccines, and the correlation coefficient(R2) between LPS concentration and its chemical light intensity(RLU value) was > 0.98, the recovery rates were between 76.4% and 192.8% when LPS concentration was between 1 and 250 EU·mL–1. The coefficient of variation of measured results was less than 25% when LPS concentration was more than 5 EU·mL–1. The limit of detection and the limit of quantitation were between 0.05 and 0.13 EU·mL–1. Then, the pyrogen of these vaccines was determined by HL60-pNL3.2 reporter gene assay, and the pyrogen concentration all was less than contaminant limit concentration.
CONCLUSION
HL60-pNL3.2 reporter gene assay has the advantages of no animal, simple and rapid operation, with wide pyrogen spectrum and can quantitative pyrogen, which can be used to detect pyrogen of live attenuated varicella vaccine, inactivated influenza vaccine and lyophilized live attenuated hepatitis A vaccine.

Objective To explore the comparison of the predictive value of three risk assessment tools on the chemotherapy-induced nausea and vomiting(CINV)in cancer patients.Methods From January 2022 to December 2022,convenience sampling was used to select 626 cancer patients with Intravenous chemotherapy in the Department of Hepatobiliary Pancreatic Oncology of Zhejiang Cancer Hospital as the research object.CINV risk assessment of patients was performed using George teams acute CINV prediction tool,Dranitsari's CINV risk assessment and CINV nomogram model.Area under curve(AUC),sensitivity,specificity and Youden index were used to compare the predictive value of the three tools.Results Totally 622 patients were ultimately included in the study,with an overall effective rate of 99.36%.There were 51.13%(318/622)patients who experienced CINV.Specifically,patients with grade 2 or higher acute CINV accounted for 18.17%(113/622).When using the three tools for acute CINV risk assessment,the AUC was respectively 0.591,0.616 and 0.558.And Dranitsari's CINV risk assessment has the highest sensitivity,acute and delayed chemotherapy-induced nausea and vomiting prediction tool has the highest specificity.Comparatively,Dranitsari's CINV risk assessment on the Yorden index is better.Conclusion The incidence of CINV in cancer patients is at a high level.The three tools can not effectively predict the risk of acute CINV.We need to develop a localized,multi-disease,standardized CINV risk assessment model for hospital.
