RESUMEN

Although carbon monoxide (CO)-based treatments have demonstrated the high cancer efficacy by promoting mitochondrial damage and core-region penetrating ability, the efficiency was often compromised by protective autophagy (mitophagy). Herein, cannabidiol (CBD) is integrated into biomimetic carbon monoxide nanocomplexes (HMPOC@M) to address this issue by inducing excessive autophagy. The biomimetic membrane not only prevents premature drugs leakage, but also prolongs blood circulation for tumor enrichment. After entering the acidic tumor microenvironment, carbon monoxide (CO) donors are stimulated by hydrogen oxide (H2O2) to disintegrate into CO and Mn2+. The comprehensive effect of CO/Mn2+ and CBD can induce ROS-mediated cell apoptosis. In addition, HMPOC@M-mediated excessive autophagy can promote cancer cell death by increasing autophagic flux via class III PI3K/BECN1 complex activation and blocking autolysosome degradation via LAMP1 downregulation. Furthermore, in vivo experiments showed that HMPOC@M+ laser strongly inhibited tumor growth and attenuated liver and lung metastases by downregulating VEGF and MMP9 proteins. This strategy may highlight the pro-death role of excessive autophagy in TNBC treatment, providing a novel yet versatile avenue to enhance the efficacy of CO treatments. Importantly, this work also indicated the applicability of CBD for triple-negative breast cancer (TNBC) therapy through excessive autophagy.

RESUMEN

XueBiJing is an intravenous five-herb injection used to treat sepsis in China.The study aimed to develop a liquid chromatography-tandem mass spectrometry(LC-MS/MS)-or liquid chromatography-ultraviolet(LC-UV)-based assay for quality evaluation of XueBiJing.Assay development involved identifying marker constituents to make the assay therapeutically relevant and building a reliable one-point cali-brator for monitoring the various analytes in parallel.Nine marker constituents from the five herbs were selected based on XueBiJing's chemical composition,pharmacokinetics,and pharmacodynamics.A selectivity test(for"similarity of response")was developed to identify and minimize interference by non-target constituents.Then,an intercept test was developed to fulfill"linearity through zero"for each analyte(absolute ratio of intercept to C response,<2%).Using the newly developed assays,we analyzed samples from 33 batches of XueBiJing,manufactured over three years,and found small batch-to-batch variability in contents of the marker constituents(4.1%-14.8%),except for senkyunolide I(26.5%).

RESUMEN

We explored the pharmacodynamic material basis and network regulatory mechanism of Fufang Yuxingcao Mixture (FYM) for the treatment of fever and inflammation. Targets of the 25 compounds in FYM were predicted according to the reverse pharmacophore method and TCMSP, UniProt database. Gene ontology (GO) function enrichment and pathway analysis of the targets was analyzed by Omicsbean software and the Kyoto Gene and Genome Encyclopedia (KEGG) database. A "compound-target-pathway-pharmacological action-effect" network was established with Cytoscape 3.6.1 software. The lipopolysaccharide (LPS)-induced RAW264.7 cell inflammation model was used to verify the anti-inflammatory effects of FYM and its 10 important components. The network pharmacology experiment showed that 25 compounds affected 97 pathways through 211 targets, of which 15 key targets [including RAC-alpha serine/threonine-protein kinase (AKT1), insulin (INS), vascular endothelial growth factor A (VEGFA), interleukin-6 (IL-6), cellular tumor antigen p53 (TP53), tumor necrosis factor (TNF), transcription factor AP-1 (JUN), caspase-3 (CASP3), matrix metalloproteinase-9 (MMP9), interleukin-8 (IL-8), prostaglandin G/H synthase 2 (PTGS2), proto-oncogene c-Fos (FOS), tyrosine-protein kinase SRC (SRC), c-Jun N-terminal kinase 1 (MAPK8), estrogen receptor 1 (ESR1)] and 46 pathways (including NF-kappa B signaling pathway, Toll-like receptor signaling pathway, MAPK signaling pathway, IL-17 signaling pathway, arachidonic acid metabolism, cAMP signaling pathway, T cell receptor signaling pathway, calcium signaling pathway, inflammatory mediator regulation of TRP channels, chemokine signaling pathway, Th1 and Th2 cell differentiation, natural killer cell mediated cytotoxicity, etc.) were related to anti-inflammatory, antipyretic, immune regulation, and analgesia. In vitro cell experiments showed that FYM and the 10 components (including isoquercitrin, luteoloside, baicalein, wogonin, wogonoside, phillyrin, forsythoside A, chlorogenic acid, isochlorogenic acid A, and sweroside) could significantly reduce the expression of nitric oxide (NO), TNF-α and IL-6 in cell supernatants, indicating that the above 10 components may be the key pharmacodynamic material basis of FYM.

RESUMEN

Berberis amurensis (Berberidaceae) is a traditional Chinese medicine, which is often used to treat hypertension, inflammation, dysentery and enteritis. It contains alkaloids, mainly including berberine, berbamine, magnoflorine, jatrorrhizine and palmatine. Berberis amurensis extracts (BAEs) is often orally taken. Oral herbs might be metabolized by intestinal bacteria in the small intestine. However, the interaction between the herb and the gut microbiota is still unknown. In the current study, UPLC/Q-TOF-MS/MS combined with Metabolitepilot and Peakview software was used to identify the metabolites of BAEs in anti-biotic cocktail induced pseudo germ-free rats and normal rats. As a result, a total of 46 metabolites in normal rats were detected and its main metabolic pathways include demethylation, dehydrogenation, methylation, hydroxylation, sulfation and glucuronidation. Only 29 metabolites existed in pseudo germ-free rats. Dehydrogenated metabolites (M29, M30, M34 and M36), methylated metabolites (M33, M41 and M46) and other metabolites were not detected in pseudo germ-free rats. The result implied that the intestinal bacteria have an influence on the metabolism of BAEs. Furthermore, this investigation might contribute to the understanding of the metabolism of BAEs, and further promote its clinical application.

RESUMEN

The goal of the present study was to determine the effectiveness and safety of hemoperfusion (HP) in beagle dogs with chronic kidney disease (CKD). The experimental protocol was approved by the Institutional Animal Care and Use Committee of Tianjin Institute of Pharmaceutical Research New Drug Evaluation Research (IACUC2019071501). Twelve CKD model beagles were randomly divided into two groups: a low-frequency treatment group (n = 6) and a high-frequency treatment group (n = 6). The dogs in the high- and low-frequency groups received HP treatment every 3 days and once per week, respectively, for two treatments, with each session lasting 2 h. The test results showed that high-frequency HP treatment significantly decreased the accumulation of toxins in the CKD beagles. Hematology, coagulation function, electrolytes and liver function indicated that the HP treatment was safe. The body index effects were consistent between the low- and high-frequency treatment groups. Therefore, HP treatment once every 3 days was safe at the animal level. Multiple HP treatments every 3 days were more conducive than weekly treatments to the removal of uremic toxins with better prognosis and had no associated safety hazards.

RESUMEN

Since the outbreak of the new coronavirus epidemic, novel coronavirus has infected nearly 100,000 people in more than 110 countries. How to face this new coronavirus epidemic outbreak is an important issue. Basic reproduction number (R0) is an important parameter in epidemiology; The basic reproduction number of an infection can be thought of as the expected number of cases directly generated by one case in a population where all individuals are susceptible to infection. Epidemiology dynamics is a mathematical model based on a susceptibility-infection-recovery epidemic model. Researchers analyzed the epidemiological benefits of different transmission rates for the establishment of effective strategy in prevention and control strategies for epidemic infectious diseases. In this review, the early use of TCM for light and ordinary patients, can rapidly improve symptoms, shorten hospitalization days and reduce severe cases transformed from light and normal. Many TCM formulas and products have wide application in treating infectious and non-infectious diseases. The TCM theoretical system of treating epidemic diseases with TCM and the treatment scheme of integrated Chinese and Western medicine have proved their effectiveness in clinical practice. TCM can cure COVID-19 pneumonia, and also shows that the role of TCM in blocking the progress of COVID-19 pneumonia.

RESUMEN

In the first 20 years of the new century, two times of coronavirus “visiting” China has become a public health emergency, which has attracted great attention at home and abroad. At the critical time of epidemic prevention and control in SARS-CoV-2 infection, the excellent achievements of traditional Chinese medicine (TCM) show the advantages and contributions of TCM. In view of the complexity of the symptoms of patients with coronavirus infection, the diversity of organ and tissue damage and functional damage or failure, how to adapt to the needs of clinical prevention and treatment is not only a problem of modern medicine, but also a problem of TCM. In this review article, the authors combed the research of TCM prescription and single medicine after understanding the cause of coronavirus infection and pathogenicity and multiple organ dysfunction and failure caused by coronavirus. Based on the emphasis on the TCM scientific research and application, the TCM therapeutic effect on SARS-CoV-2 infection is discussed. The framework of new drug research and development based on possible “target” is proposed, and we put forward the ideas for researching new TCM products through the expanding molecular mechanism of infection.

RESUMEN

Objective: To elucidate the effect of sulfur fumigation on the content of chemical composition and quality of Panacis Quinquefolii Radix, and to discuss the identification method of sulfur fumigated Panacis Quinquefolii Radix. Method: The content changes of ginsenoside Rb1, Re, Rg1 in Panacis Quinquefolii Radix were determined by HPLC-DAD before and after sulfur fumigation. The content changes of 11 inorganic elements in Panacis Quinquefolii Radix before and after sulfur fumigation were detected by microwave digestion method and inductively coupled plasma emission spectrometry tandem mass spectrometry (ICP-MS). The quality difference of Panacis Quinquefolii Radix before and after sulfur fumigation was qualitatively distinguished combined with the principal component analysis. Result: Three ginsenosides were well separated and showed good linearity with R2 ≥ 0.999.Before sulfur fumigation, the contents of ginsenoside Rg1, Re and Rb1 in Panacis Quinquefolii Radix were (0.897±0.045), (13.092±0.639), (12.896±0.430) g ·kg-1, respectively. After sulfur fumigation, the contents of these three components in Panacis Quinquefolii Radix were (0.807±0.032), (11.968±0.627), (11.752±0.696) g ·kg-1, respectively. After fumigation, the contents of inorganic elements (Cr, Mn, Co, Cu, As, Se, Ag, Cd, Sb, Pb and Fe) from Panacis Quinquefolii Radix increased in varying degrees. According to the distribution results of three-dimensional (3D) scattered points, sulfur and non-sulfur fumigation products of Panacis Quinquefolii Radix could be effectively distinguished. Conclusion: After sulfur fumigation, the contents of ginsenoside Re and Rb1 in Panacis Quinquefolii Radix decrease significantly, but the contents of 11 inorganic elements increase, suggesting that sulfur fumigation may have a great influence on the quality of Panacis Quinquefolii Radix.
