Journal of Pharmaceutical Practice and Service.2025;43(12):583-590. doi:10.12206/j.issn.2097-2024.202312024

Colorectal cancer is one of the most common malignant tumors, which is a great threat to human life and health. The change of bile acid homeostasis can activate their corresponding receptors to regulate the immune functions, which is closely related to the occurrence of colorectal cancer. In addition, some bile acids can directly induce colorectal cancer and play an important role in the development of colorectal cancer. In this paper, the metabolic process of bile acids in vivo and the immunomodulatory role of bile acid receptors were reviewed, and the evidence of associations between bile acids and colorectal cancer were summarized, which showed the rebalancing the bile acid levels might play a role in the prevention or treatment of colorectal cancer.

Objective To explore the mechanism of Xiakucao Xiaoliu Mixture against non-small cell lung cancer （NSCLC）. Methods The effective components of Xiakucao Xiaoliu Mixture were screened by TCMSP, BATMAN-TCM database and literature reviews. The targets of effective components were predicted. NSCLC related targets were collected by GeneCards, OMIM, PharmGKB, TTD and Drugbank, combined with the differential genes of Xiakucao Xiaoliu Mixture against Lewis lung cancer mice. The intersection targets of Xiakucao Xiaoliu Mixture against NSCLC were obtained. Cytoscape software was used to construct the network diagram of traditional Chinese medicine-active ingredients-core targets. STRING database was used to construct PPI network diagram. GO function enrichment analysis and KEGG pathway enrichment analysis of the intersection targets were performed by Metascape database to predict the key targets and active components of Xiakucao Xiaoliu Mixture against NSCLC, and Schrodinger software was used to perform molecular docking verification. Results The 32 active components and 24 intersection targets of Xiakucao Xiaoliu Mixture against NSCLC were obtained. 11 core targets such as ESR1, MAPK1 were found. The mechanism of action may be related to 30 signaling pathways such as cellular senescence, receptor activation, prolactin signaling pathway. Conclusion The active components of Xiakucao Xiaoliu Mixture act on multiple targets and signaling pathways to regulate complex biological processes. By regulating ESR1 agsinst NSCLC, it may play an important role in improving the survival rate and prognosis of female patients.

Journal of Pharmaceutical Practice and Service.2025;43(12):599-602. doi:10.12206/j.issn.2097-2024.202311012

Objective To explore the effect of different packing contents of solid phase extraction column, repeated use times and solid phase extraction column under pressure on the determination of morphine content in compound liquorice oral solution. Methods The component was performed by high performance liquid chromatography （HPLC） equipped with the C₈ （4.6 mm × 150 mm, 5 μm） chromatographic column. The mobile phase consisted of acetonitrile-2.5 mmol/L sodium heptanesulfonate solution-50 mmol/L potassium dihydrogen phosphate solution （5∶18∶18）. The flow rate was 1.0 ml/min with the 220 nm detection wavelength, 20 μl injection volume and 30℃ column temperature. Results It was found that the SPE column produced of 500 mg had a higher recovery rate of morphine, and the RSD value was small. It was found that SPE column could be reused for up to 3 times under the condition of guaranteeing recovery rate.In the pressurized experiment,at the flow rate of 0.5 ml/min, the measured morphine content was basically consistent with that measured at atmospheric pressure. Conclusion The determination of morphine in compound liquorice oral solution could be carried out by C₁₈ solid phase extraction column of 500 mg. Under pressure, the flow rate was about 0.5 ml/min for morphine recovery, which could achieve high recovery of morphine in compound liquorice oral solution and improve the detection efficiency of morphine.

Na LI ; Chengwen HUANG ; Xiujuan SUN ; Xiaohong WANG ; Li ZHANG ; Xingpo WANG

Journal of Pharmaceutical Practice and Service.2025;43(12):619-624. doi:10.12206/j.issn.2097-2024.202411032

Objective To explore the cost effectiveness of osimertinib and gefitinib in the treatment of advanced non-small cell lung cancer （NSCLC） with epidermal growth factor receptor （EGFR） mutation. Methods A total of 52 advanced NSCLC patients with EGFR mutation treated by osimertinib were selected as group A from June 2021 to August 2022 at the Chengde Central Hospital, and 52 patients treated by gefitinib were selected as group B according to the propensity score matching method in 1∶1 ratio. The treatment cost and effect of the two groups of patients were compared, and the cost-effectiveness ratio was calculated, and sensitivity analysis was conducted. Results The total effective rate of group A was higher than that of group B （90.38% vs 71.15%, χ²=6.190, P=0.013）. The drug cost and total treatment cost of group A were higher than those of group B（P<0.05）, and other direct costs were lower than those of group B （P<0.05）. The incremental cost effectiveness ratio of group A was 374.71. After the cost-effectiveness sensitivity analysis on adjusting drug costs to decrease by 10% and the total effective rate to decrease by 10% of the two groups, the sensitivity analysis results were basically consistent with the original results. Conclusion Based on the latest prices and actual case data of osimertinib and gefitinib, osimertinib was better than gefitinib in the treatment of advanced NSCLC patients with EGFR mutation. Although gefitinib had lower treatment costs, osimertinib had more cost effectiveness advantages. These findings could provide important reference for the clinical development of treatment plans for advanced NSCLC patients with EGFR mutations.

Journal of Pharmaceutical Practice and Service.2025;43(12):631-636. doi:10.12206/j.issn.2097-2024.202404071

Objective To analyze the usage of pediatric drugs in 17 pediatric specialty hospitals from 2016 to 2020, and provide reference and guidance for the development of the essential medicine list （EML） for children and the improvement of the National Reimbursement Drug List （NRDL） in China. Methods Based on the pediatric medication monitoring data from 17 children's specialized hospitals reported to the Chinese Medical Economic Information Network (CMEI) of the Chinese Pharmaceutical Association between 2016 and 2020, this study analyzes the overall situation of the sample hospitals and the clinical use of pediatric drugs according to the major categories of the Anatomical Therapeutic Chemical Classification System （ATC）. Results In the various ATC categories, the trend of systemic use of anti-infective drugs decreasing was significant in the average hospital expenditure, while the trend of respiratory and digestive system and metabolic drugs decreasing was significant in the average hospital DDDS. In 2020, the average number of hospital grade standards for essential drugs （2018 version） accounted for 15.82% of the total number of drug use standards, while the average number of hospital grade standards for medical insurance （2019 version） accounted for 8.23% of the total number of drug use standards. Conclusion The use of pediatric medication in sample hospitals from 2016 to 2020 was generally reasonable, and there would still a certain gap between the actual clinical usage habits with the existing EML and NRDL，which still need to be adjusted.
