  Objective   To study the reversal effect of Shenfu decoction(SFD)on adriamycin-induced cardiomyopathy and explore its mechanism by using serum metabolomic technology.   Methods  The BALB/c mouse model of cardiomyopathy induced by adriamycin was established. The corresponding intervention was given. The serum lactate dehydrogenase(LDH)and creatine phosphatase isoenzyme MB(CK-MB)were measured. The ejection fraction (EF) and shortening fraction (FS) were measured by echocardiography. Mouse serum was collected for gas chromatography-mass spectrometry (GC-MS) analysis. The data obtained was analyzed by multivariate and univariate statistical analysis to compare the changes of endogenous metabolites in the serum of mice in the normal group, model group and Shenfu decoction treatment group, to find the potential biomarkers of Shenfu decoction to reverse the adriamycin-induced cardiomyopathy. Metabolic pathway analysis was used to explore the targeted metabolic pathway of Shenfu decoction.   Results  The levels of serum LDH and CK-MB in the model group were increased significantly, and the values of EF and FS decreased significantly, indicating that the model was successfully established. The above indicators were significantly improved after treatment with Shenfu decoction. 13 potential biomarkers of adriamycin-induced cardiomyopathy were identified by metabonomic analysis, and Shenfu decoction had significant reversal effect on 11 metabolites. Metabolic pathway analysis showed that the synthesis of phenylalanine, tyrosine and tryptophan, arachidonic acid metabolism, phenylalanine metabolism, tricarboxylic acid cycle and dicarboxylic acid metabolism were the main targeted metabolic pathways of Shenfu decoction.   Conclusion  Shenfu decoction can reverse adriamycin-induced cardiomyopathy by regulating the unbalanced synthesis of phenylalanine, tyrosine and tryptophan, as well as the metabolism of arachidonic acid, phenylalanine, dicarboxylic acid and tricarboxylic acid cycle.

  Objective   To explore the mechanism of motherwort in the treatment of nerve injury.   Methods   The active components of motherwort were obtained by searching TCMSP and BATMAN-TCM databases. The action targets of candidate compounds were collected and predicted from TCMSP and SwissTargetPrediction (STP) databases. The target genes corresponding to the active components of motherwort were obtained by using the standardized database of disease targets (Uniprot). The potential targets of motherwort in the treatment of nerve injury were obtained by mapping the disease genes of nerve injury with the three databases of Genecards, DisGenet and OMIM. The network topology analysis software Cytoscape 3.6.0 was used to construct the action target network of motherwort active components. The protein interaction platform database (STRING) was used to construct the interaction relationship between action targets. The target protein interaction (PPI) network was constructed by introducing Cytoscape 3.6.0 software. Through STRING database, GO enrichment analysis and KEGG pathway enrichment analysis were carried out to analyze the target points of motherwort in the treatment of nerve injury.   Results  19 active components were screened from motherwort, involving 654 action targets, including 426 action targets related to nerve injury and 6 key targets. These target genes were mainly involved in biological regulation, oxidative stress response and cell communication and other biological processes. Molecular functions were mainly related to protein binding, ion binding and catalytic reduction. They were enriched outside the cell membrane. Its mechanism was related to signal pathways such as MAPK, Toll-like receptor, PI3K-Akt, TNF, IL-17, and apoptosis.   Conclusion  The active components of motherwort may play a protective role on nerve injury through anti-inflammation, anti-apoptosis and promoting cell growth.

  Objective   To study the effect and mechanism of epigallocatechol gallate (EGCG) combined with trastuzu-mab on the proliferation of human epidermal growth factor receptor 2 (HER2) overexpressing breast cancer cells.   Methods   Trastuzumab was expressed and purified. The cell proliferation of HER2 overexpressing breast cancer cells BT474 and SK-BR-3 treated with trastuzumab, EGCG, or trastuzumab plus EGCG was evaluated by CCK8 assay. The effects of EGCG and trastuzumab on the expression of HER2, epidermal growth factor receptor (EGFR), mitogen-activated protein kinase (MAPK), protein kinase B (Akt), and their phosphorylated proteins in BT474 breast cancer cells were detected by Western blot.   Results   The results of cell proliferation assay indicated that EGCG and trastuzumab, alone or in combination, effectively inhibited the proliferation of BT-474 and SK-BR-3 cells. And within a certain concentration range, EGCG and trastuzumab showed a synergistic proliferation inhibitory effect on HER2 overexpressing breast cancer cells. Consistent with these results, Western blot results showed that trastuzumab and EGCG, alone or in combination significantly reduced the phosphorylation levels of Akt, MAPK, EGFR, and HER2 in BT474 cells. Moreover, the inhibition effect of EGCG plus trastuzumab was significantly more potent than either EGCG or trastuzumab.   Conclusion   EGCG and trastuzumab could synergistically inhibit the proliferation of HER2 overexpressing breast cancer cells, which may be related to the regulation of Akt and MAPK signaling pathways.

Abstract(2103) HTML (2852) PDF (855KB)(42)
  Objective  To understand the current situation of dispensing errors and effective prevention and control measures in outpatient pharmacies in domestic hospitals, in order to further improve the quality of drug dispensing.   Methods  The Chinese journal database was retrieved from 2015 to 2020 for the literature on the dispensing errors of outpatient pharmacies and the continuous improvement of the quality after the measures were taken in secondary and tertiary hospitals.   Results  Of the 146 literatures retrieved, 13 were included in the analysis (11 in tertiary hospitals and 2 in secondary hospitals). Before the improvement, the median of the drug dispensing error rate was 5.1‰, and after the improvement it was 1.1‰. Before and after the improvement, the types of drug dispensing errors were mainly quantity errors (52.5% vs. 51.3%), variety errors (28.3% vs. 28.7%), specifications and dosage forms errors (6.2% vs. 6.7%), and labeling errors (2.1% vs. 2.9%). The improvement measures taken for the reasons of dispensing errors have a high overlap rate, and they are concentrated in two aspects: personnel factors and drug factors.   Conclusion  The use of continuous quality improvement tools in hospital outpatient pharmacy to control and prevent dispensing errors is still a hotspot of current research. The composition of the types of errors after improvement has basically not changed. The implemen-tation of standardized operating procedures and other continuous improvement comprehensive measures can effectively reduce the incidence of dispensing errors, and contribute to the implementation of the “Expert Consensus on Medication Error Management in China”.
