Safety evaluation of Tibetan medicine Qishiwei Zhenzhu Pills based on serum pharmacochemistry and network pharmacology / 中国中药杂志

To explore the mechanism of the active ingredients of Qishiwei Zhenzhu Pills in inhibiting the hepatorenal toxicity of the zogta component based on serum pharmacochemistry and network pharmacology, thereby providing references for the clinical safety application of Qishiwei Zhenzhu Pills. The small molecular compounds in the serum containing Qishiwei Zhenzhu Pills of mice were identified by high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS). Then, by comprehensively using Traditional Chinese Medicines Systems Pharmacology(TCMSP), High-throughput Experiment-and Reference-guided Database(HERB), PubChem, GeneCards, SuperPred, and other databases, the active compounds in the serum containing Qishiwei Zhenzhu Pills were retrieved and their action targets were predicted. The predicted targets were compared with the targets of liver and kidney injury related to mercury toxicity retrieved from the database, and the action targets of Qishiwei Zhenzhu Pills to inhibit the potential mercury toxicity of zogta were screened out. Cytoscape was used to construct the active ingredient in Qishiwei Zhenzhu Pills-containing serum-action target network, and STRING database was used to construct the protein-protein interaction(PPI) network of intersection targets. The Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analyses were carried out on the target genes by the DAVID database. The active ingredient-target-pathway network was constructed, and the key ingredients and targets were screened out for molecular docking verification. The results showed that 44 active compounds were identified from the serum containing Qishiwei Zhenzhu Pills, including 13 possible prototype drug ingredients, and 70 potential targets for mercury toxicity in liver and kidney were identified. Through PPI network topology analysis, 12 key target genes(HSP90AA1, MAPK3, STAT3, EGFR, MAPK1, APP, MMP9, NOS3, PRKCA, TLR4, PTGS2, and PARP1) and 6 subnetworks were obtained. Through GO and KEGG analysis of 4 subnetworks containing key target genes, the interaction network diagram of active ingredient-action target-key pathway was constructed and verified by molecular docking. It was found that taurodeoxycholic acid, N-acetyl-L-leucine, D-pantothenic acid hemicalcium, and other active ingredients may regulate biological functions and pathways related to metabolism, immunity, inflammation, and oxidative stress by acting on major targets such as MAPK1, STAT3, and TLR4, so as to inhibit the potential mercury toxicity of zogta in Qishiwei Zhenzhu Pills. In conclusion, the active ingredients of Qishiwei Zhenzhu Pills may have a certain detoxification effect, thus inhibiting the potential mercury toxicity of zogta and playing a role of reducing toxicity and enhancing effect.

Intermittent pressure imitating rolling manipulation ameliorates injury in skeletal muscle cells through oxidative stress and lipid metabolism signalling pathways.

BACKGROUND: Traditional Chinese medicine manipulation (TCMM) is often used to treat human skeletal muscle injury, but its mechanism remains unclear due to difficulty standardizing and quantifying manipulation parameters. METHODS: Here, dexamethasone sodium phosphate (DSP) was utilized to induce human skeletal muscle cell (HSkMC) impairments. Cells in a three-dimensional environment were divided into the control normal group (CNG), control injured group (CIG) and rolling manipulation group (RMG). The RMG was exposed to intermittent pressure imitating rolling manipulation (IPIRM) of TCMM via the FX­5000™ compression system. Skeletal muscle damage was assessed via the cell proliferation rate, superoxide dismutase (SOD) activity, malondialdehyde (MDA) content and creatine kinase (CK) activity. Isobaric tagging for relative and absolute protein quantification (iTRAQ) and bioinformatic analysis were used to evaluate differentially expressed proteins (DEPs). RESULTS: Higher-pressure IPIRM ameliorated the skeletal muscle cell injury induced by 1.2 mM DSP. Thirteen common DEPs after IPIRM were selected. Key biological processes, molecular functions, cellular components, and pathways were identified as mechanisms underlying the protective effect of TCMM against skeletal muscle damage. Some processes (response to oxidative stress, response to wounding, response to stress and lipid metabolism signalling pathways) were related to skeletal muscle cell injury. Western blotting for 4 DEPs confirmed the reliability of iTRAQ. CONCLUSIONS: Higher-pressure IPIRM downregulated the CD36, Hsp27 and FABP4 proteins in oxidative stress and lipid metabolism pathways, alleviating excessive oxidative stress and lipid metabolism disorder in injured HSkMCs. The techniques used in this study might provide novel insights into the mechanism of TCMM.

[Treatment of early and mid-term primary biliary cirrhosis by Qingying Huoxue Decoction Combined ursodeoxycholic acid: a clinical observation].

UNLABELLED: OBJECTIVE To observe the clinical efficacy by Qingying Huoxue Decoction (QHD) combined ursodeoxycholic acid (UDCA) in treating patients with early and mid-term primary biliary cirrhosis (PBC). METHODS Totally 78 patients were randomly assigned to the treatment group and the control group, 39 in each group. All patients received basic treatment and took UDCA (at the daily dose of 13-15 mg/kg). Patients in the treatment group took QHD, one dose per day. The treatment course for all was 6 weeks. Clinical efficacy, gamma-glutamyl transferase (γ-GGT), alkaline phospatase (ALP), TBIL, alanine aminotransferase (ALT), and aspartate transaminase (AST) were observed before and after treatment. RESULTS Totally 21 (53. 8%) patients obtained complete response in the treatment group, with statistical difference when compared with that of the control group (11 cases, 30. 8%). Levels of GGT, ALP, ALT, AST, and TBIL decreased in the two groups after treatment (P < 0.01). Levels of ALP, GGT, and TBIL were obviously lower in the treatment group than in the control group (P < 0.05). CONCLUSIONS: QHD combined UDCA in treating early and mid-term PBC patients was superior to the effect of using UDCA alone. It also could improve patients' liver function.

A study on the extraction process of active ingredients from Akebia Stem and an analysis of their anti-gastric cancer activity.

The study investigated the extraction process of active ingredients from akebia stem and an analysis of their anti-gastric cancer activity. Three different extraction methods were used to obtain extracts, namely the decoction method (group A), reflux extraction method (group B), and maceration method (group C), of which reflux extraction method and maceration method used ethanol as the extraction solvent, while decoction method used distilled water for extraction. The differences in anti-gastric cancer activity of the three extracts were compared. MTT assay was used to test and compare the inhibitory effects of extracts obtained in A, B, and C groups on gastric cancer cells. The results showed that the dry extract obtained by heat reflux extraction with "water-ethanol" ratio of 1:2, extractant volume of 70 ml, with ethanol as extraction solvent presented the best inhibitory activity on gastric cancer SGC-7901 cells in this study. Its inhibitory effect did not change over time, and was directly proportional to the concentration.

Control group were treated with a placebo of the same color for oral use and external application. The delivery times, method and the time of therapy were all the same as the treatment group. After 30 days' treatment, the effective indexes of VAS pain score and swelling condition were observed in both groups.</p><p><b>RESULTS</b>VAS pain score: the treatment group decreased (3.8 +/- 0.8) points and the control group decreased (1.0 +/- 0.3) points, the difference between the two groups was significantly (P < 0.01). There was significantly difference in volume decrease of the swelling limb between treatment group (21.8 +/- 2.5) ml and the control group (10.3 +/- 2.1) ml (P < 0.01). The efficiency difference between treatment group and control group was significantly(P<0.01).</p><p><b>CONCLUSION</b>With the different treatment based on different syndrome and emphasis on the nourishment of bone and soft tissue, treated by Chinese medicine to promote blood circulation and remove blood stasis in stagnation of vital energy and blood stasis, RSD get a favorable result.</p>
