Opium is obtained by air-drying the milky latex extracted from the unripe capsules of the opium poppy(Papaver somniferum).This latex is rich in benzylisoquinoline alkaloids(BIA),with major active compounds in-cluding morphine,codeine,thebaine,papaverine,and noscapine.Compound licorice oral solution and compound licorice tablets are derivative drugs containing opium.Initially classified as over-the-counter(OTC)medications,both formulations were later reclassified as prescription drugs by the National Medical Products Administration(NMPA),restricting their purchase without proper authorization.Although the national pharmacopeia standards specify the morphine content in the opium raw materials used for compound licorice oral solution and tablets,they lack mandatory requirements for the detection and quantification of the other four major alkaloids.Given the unique nature of opium raw materials and the stringent regulatory requirements for such drugs,it is imperative to enhance and refine simultaneous detection and control methods for all alkaloid components in these products.Furthermore,the establishment of scientific and reasonable detection and control standards for preservatives in compound licorice formulations is crucial to improving overall product quality management and ensuring drug safety and efficacy.This study analyzes and discusses the quality standards,detection methods,and research progress for opium and com-pound licorice preparations,aiming to explore the potential for technological innovation and ensure the safe use of these medications.

Objective To investigate the relationship between serum high mobility group protein B1(HMGB1),C1q/TNF-associated protein 3(CTRP3)and pain degree and lumbar function.Methods A total of 145 patients with lumbar spinal stenosis treated in the hospital from September 2021 to August 2023 were retrospectively selected as the study objects,and were divided into single-segment group(89 cases)and multi-segment group(56 cases)according to the number of lumbar spinal stenosis segments.Serum levels of HMGB1 and CTRP3 were detected by enzyme-linked immunosorbent assay.The clinicopathological features such as pain degree,lumbar function and serum levels of HMGB1 and CTRP3 were compared between the two groups.The correlation of serum HMGB1 and CTRP3 levels with pain degree and lumbar function were ana-lyzed,and the factors influencing the number of segments of lumbar stenosis were analyzed by multivariate Logistic regression.The diagnostic value of serum HMGB1 and CTRP3 levels on lumbar function of patients was analyzed by receiver operating characteristic(ROC)curve.Results Visual analogue scale(VAS)score and serum HMGB1 level in multi-segment group were higher than those in single-segment group(P＜0.05),Japanese Orthopaedic Association(JOA)score and serum CTRP3 level were lower than those in single-seg-ment group(P＜0.05).Serum HMGB1 level was negatively correlated with CTRP3 and JOA score in pa-tients with lumbar spinal stenosis(r=-0.544,-0.616,P＜0.001),and positively correlated with VAS score(r=0.453,P＜0.001).The serum CTRP3 level was negatively correlated with VAS score(r=-0.550,P＜0.001),and positively correlated with JOA score(r=0.619,P＜0.001).JOA score was nega-tively correlated with VAS score(r=-0.485,P＜0.001).Multivariate Logistic regression analysis showed that JOA score and serum CTRP3 level were protective factors for multi-segmental stenosis(P＜0.05),VAS score and serum HMGB1 level were risk factors for multi-segmental stenosis(P＜0.05).The analysis of ROC curve showed that serum HMGB1 and CTRP3 levels could be used as diagnostic indexes of lumbar spinal function in patients with lumbar spinal stenosis,and the combined diagnosis effect was better(P＜0.05).Conclusion Serum levels of HMGB1 and CTRP3 are closely related to pain degree and lumbar function in pa-tients with lumbar spinal stenosis.The combination of the two indexes can be used for the clinical diagnosis of lumbar function in patients with lumbar spinal stenosis.

ABATRACT OBJECTIVE To utilize the pharmacophore model-molecular docking combined with the virtual screening strategy of free energy calculation and the chemical bioinformatics method of traditional Chinese medicine in cell biology experiments to investigate the components of Guiqi Baizhu prescription that target phosphatidylinositol 3-kinase(PI3K) and inhibit the proliferation of uveal melanoma(UM) cells. METHODS The pharmacophore model of PI3K inhibitor was constructed, and the compounds of Guiqi Baizhu prescription were virtual screened. The components that fit the pharmacophore model were calculated by molecular docking and binding free energy, and the potential inhibitory components were selected for biological experimental evaluation. The effects of potential inhibitory components on UM cell proliferation were detected by CCK-8 and clonal formation assay. Flow cytometry was used to detect the cell cycle and apoptosis of UM cells. The mitochondrial membrane potential of UM cells was detected using JC-10 staining. The expressions of PI3K and downstream pathway proteins were detected by Western blotting.RESULTS The pharmacophore model included 2 hydrogen bond receptors, 2 aromatic ring centers, and exclusion volumes. The results of the CCK-8 experiment showed that quercetin, tangerine, and nobiletin at concentrations of 10, 20, 40, 80 μmol·L−1, and cyrtin at concentrations of 20, 40, 80 μmol·L−1, were able to inhibit the proliferation of UM cells. The clonal formation experiment showed that quercetin, tangerine, nobiletin, and morusin, at different concentrations, could significantly inhibit the clonal proliferation of UM cells. Flow cytometry showed that UM cells were arrested in the G0/G1 phase by tangeretin and quercetin, while UM cells were arrested in the G2/M phase by nobiletin and morusin. The results of JC-10 staining showed that quercetin, nobiletin, tangeretin, and morusin could reduce the mitochondrial membrane potential of UM cells. Western blotting results showed that 4 compounds could target PI3K, but their downstream pathways were different.CONCLUSION Based on the method of chemical bioinformatics in traditional Chinese medicine, this study explores the material basis for the inhibition of UM cell proliferation by the Guiqi Baizhu prescription. It also provides insights for the modern development of traditional Chinese medicine prescription.

OBJECTIVE To explore the effectiveness, potential mechanism and compatibility characteristics of efficacy groups of Dunhuang medical prescription Daxiefei decoction in preventing and treating pneumonia based on chemical bioinformatics method. METHODS To study the effect of Daxiefei decoction freeze-dried powder solution on the proliferation activity of lung epithelial cells through cell experiments. Daxiefei decoction was divided into three groups: clearing away heat group, resolving phlegm group, and nourishing Yin group according to its efficacy characteristics. The chemical components of Daxiefei decoction were obtained by TCMSP database and literature search, and the targets were predicted in Swiss Target Prediction database. Pneumonia disease targets were obtained by DrugBank, TTD, Genecards and DisGeNET databases. STRING database and Cytoscape were used to construct the intersection target interaction network and "drug-component-target- pathway" network and DAVID database was used for KEGG pathway enrichment analysis. The network was used to analyze the scientific connotation of the compatibility of efficacy groups. Furthermore, molecular docking was used to evaluate the target-compound affinity and molecular dynamics was used to explore the dynamic molecular mechanism. RESULTS Cell experiments showed that Daxiefei decoction can maintain the proliferation of lung epithelial cells, reverse the decrease of mitochondrial activity induced by LPS and reduce apoptosis. Complex network analysis showed that the pathways enriched by the three functional groups contained in Daxiefei decoction were mainly distributed in two modules: inflammation regulation and reducing airway mucus hypersecretion. Each module was connected by a common target gene and had its own focus. The results of molecular docking showed that the components quercetin, baicalein, isorhamnetin etc. might be the effective multi-target components of Daxiefei decoction. SRC, EGFR, PPARA etc. had good affinity with each potential active component, which might be a potential target of Daxiefei decoction for preventing and treating pneumonia. Molecular dynamics simulation showed that the potential active component quercetin formed stable intermolecular interactions with SRC. CONCLUSION This study initially reveal the material basis and molecular mechanism of Daxiefei decoction in the prevention and treatment of pneumonia. It also explores the scientific connotation of Daxiefei decoction in the prevention and treatment of pneumonia with different efficacy groups, and its modern development and clinical application provide chemical bioinformatics basis.

OBJECTIVE: To analyze the clinical phenotype and genetic basis for a child with acute form of tyrosinemia type I (TYRSN1). METHODS: A child with TYRSN1 who presented at the Gansu Provincial Maternal and Child Health Care Hospital in October 2020 was selected as the subject. The child was subjected to tandem mass spectrometry (MS-MS) and urine gas chromatography-mass spectrometry (GC-MS) for the detection of inherited metabolic disorders, in addition with whole exome sequencing (WES). Candidate variants were validated by Sanger sequencing. RESULTS: The child's clinical features included abdominal distension, hepatomegaly, anemia and tendency of bleeding. By mass spectrometry analysis, her serum and urine tyrosine and succinylacetone levels have both exceeded the normal ranges. WES and Sanger sequencing revealed that she has harbored c.1062+5G>A and c.943T>C (p.Cys315Arg) compound heterozygous variants of the FAH gene, which were inherited from her father and mother, respectively. Among these, the c.943T>C was unreported previously. CONCLUSION Considering her clinical phenotype and result of genetic testing, the child was diagnosed with TYRSN1 (acute type). The compound heterozygous variants of the FAH gene probably underlay the disease in this child. Above finding has further expanded the spectrum of FAH gene variants, and provided a basis for accurate treatment, genetic counseling and prenatal diagnosis for her family.
