As people’s attention to health continues to increase, the market demand for traditional Chinese medicine (TCM) is growing steadily. The quality and safety of Chinese medicinal materials have attracted unprecedented social attention. In particular, the issue of exogenous harmful residue pollution in TCM has become a hot topic of concern for both regulatory authorities and society. The Chinese Pharmacopoeia 2025 Edition further refines the detection methods and limit standards for exogenous harmful residues in TCM. This not only reflects China’s high-level emphasis on the quality and safety of TCM but also demonstrates the continuous progress made by China in the field of TCM safety supervision. Basis on this study, by systematically reviewing the development history of the detection standards for exogenous harmful residues in TCM and analyzing the revisions and updates of these detection standards in the Chinese Pharmacopoeia 2025 Edition, deeply explores the key points of the changes in the monitoring standards for exogenous harmful residues in TCM in the Chinese Pharmacopoeia 2025 Edition. Moreover, it interprets the future development directions of the detection of exogenous residues in TCM, aiming to provide a reference for the formulation of TCM safety supervision policies.

Objective:To evaluate the clinical effectiveness and safety of Jiuwei-Zhuhuang San plus amoxilcillin sodium and sulbactam sodium in the treatment of bacterial pneumonia in children. Methods:A total of 120 patients with bacterial pneumonia in children from 1 year to 14 years old were randomly divided into the study group ( n=90) and the control group ( n=30) with ratio 3 to 1, the random sequence created by SAS software. Both groups were treated with amoxilcillin sodium for basic treatment, the observation group was treated with Jiuwei-Zhuhuang San. Both groups were treated for 1 week and followed up for 1 week. The cough frequency, clinical effective rate, symptoms and signs score, Traditonal Chinese medicine (TCM) pattern scores and adverse event rate were observed. Results:Eighteen cases were dropped and eliminated in the observation group, and 4 cases were dropped and eliminated in the control group, so 72 of observation group and 26 of control group were analyzed. After treatment, the clinical effective rate of the observation group was 27.8% (20/72), and the control group was 0% (0/26), where the difference was significant ( χ2=7.445, P=0.006). The difference of TCM syndrome score before and after treatment in the observation group (-16.8 ± 8.2 vs. -11.0 ± 5.8, t=-3.858) was lower than that of the control group ( P<0.01). There was significant difference between the two groups ( Z=-2.347, P= 0.019) in the TCM syndrome. The cough frequency of the observation group was 41.7% (30/72), and the control group was 26.9% (7/26). There wasn’t any significant differences in the cough frequency between two groups ( P>0.05). There was no statistical difference in symptoms and signs score or adverse event rate between two groups ( P>0.05). Conclusion:On the basis of amoxicillin sodium and sulbactam sodium, combined use of Jiuwei-Zhuhuang San can improve the clinical effectiveness of children with bacterial pneumonia.
