The possible mechanisms of Erhuang decoction in the treatment of acute lung injury based on network pharmacology / 药学学报

Network pharmacological approaches were used to predict the components, targets and pathways of Erhuang decoction (EhD) in the treatment of acute lung injury (ALI). The SwissTargetPrediction platform, DisGeNET, Therapeutic Target Database (TTD), GeneCards and Online Mendelian Inheritance in Man (OMIM) databases were used to predict potential targets of EhD and were integrated with the predicted targets for the treatment of ALI. A protein-protein interaction network model was constructed by using String database and Cytoscape software; the DAVID platform was used for Gene Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis. A network of drug components-targets-pathways was constructed by Cytoscape software and the SwissDock platform was used to dock the molecules of EhD found in blood with the key disease targets. An ALI model was established in mice and inflammatory factor detection and Western blot protein expression experiments with lung tissue sections were carried out to verify the effect of EhD in the treatment of ALI. Animal experiment ethical requirements were approved by the Ethical Committee Experimental Animal Center of Shandong University (Grant Number: 2016020). We identified 148 potential targets including signal transducer and activator of transcription 3 (STAT3), vascular endothelial cell growth factor A (VEGFA), RAC-alpha serine/threonine-protein kinase (AKT1), and nuclear factor-kappa B/p65 (RELA). The potential targets are largely associated with the biological processes of inflammation, oxidative stress, and apoptosis. Additional pathways relate to cancer, VEGF signaling, mitogen-activated protein kinase (MAPK) signaling, and Toll-like receptors (TLRs) signaling, along with other signaling pathways. Pharmacodynamic experiments showed that EhD could significantly reduce the content of inflammatory factors and the degree of lung injury of ALI mice. Western blot revealed that EhD could significantly decrease the expression of NF-κB/p65 and upregulate the expression of NF-kappa-B inhibitor alpha (IκBα). From the perspective of network pharmacology, the mechanisms of EhD in the treatment of ALI is consistent with the characteristics of multiple ingredients, multiple targets and multiple pathways. This research provides a reference for further study of the mechanism of this traditional Chinese medicine.

Effect of 5 warm-hot nature Chinese drugs for promoting blood circulation and removing blood stasis on 5-HT, NE, and endocrine hormones of rats of cold coagulation and blood stasis syndrome / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To study the mechanism of warm-hot nature Chinese drugs (WHNCD) for promoting blood circulation and removing blood stasis (PBCRBS) for intervening model rats of cold coagulation and blood stasis syndrome (CCBSS).</p><p><b>METHODS</b>CCBSS rat model was set up in outbred SD rats using ice water immersion method. Totally 300 successfully modeled CCBSS rats were randomly divided into 5 groups according to the principle of balance weight, 60 in each group. Contents of triothyrone (T3), tetraiodothyroine (T4), progesterone (P), 5-hydroxytryptamine (5-HT), and noradrenalin (NE) were paralleledly detected in all groups. Then rats in each group were subdivided into 6 subgroups as the model group, the curcuma group, the Ligsticum Chuanxiong group, the safflower group, the Rhizoma Corydalis group, and the Olibanumg group. Besides, 5 normal control groups were set up for 5 indices, 50 rats in total. We need 70 rats (7 groups) to finish observing 1 index, 350 rats in total for 5 indices. Except those in the model group and the normal control group, rats were administered with corresponding decoction at 20 g crude drugs/kg body weight by gastrogavage, 3 mL each time, once daily for 7 successive days. Equal volume of normal saline was given to rats in the normal control group and the model group. Contents of T3, T4, P, 5-HT, and NE were detected before treatment and 1 week after treatment.</p><p><b>RESULTS</b>Compared with before treatment in the same group, T3 increased in the Ligsticum Chuanxiong group and the Olibanumg group, 5-HT increased in the Ligsticum Chuanxiong group, T4, NE, and P increased in all medicated groups (P < 0.05). Compared with the normal control group, contents of T3, T4, 5-HT, NE, and P in the model group decreased (P < 0.05). Compared with the model group, contents of T3, T4, 5-HT, and NE increased in each medicated group (P < 0.05). There was statistical difference in contents of P between the Ligsticum Chuanxiong group and the Olibanumg group (P < 0.05).</p><p><b>CONCLUSIONS</b>WHNCD for PBCRBS had regulatory roles in serum contents of T3, T4, P, and NE in modeled rats of CCBSS. They could promote the thyroid gland-gonadal axis function, enhance the function of the endocrine system, which might be one of the pharmacodynamic mechanism of WHNCD for PBCRBS in intervening CCBSS.</p>

Effects of Radix aconiti lateralis preparata and Rhizoma zingiberis on energy metabolism and expression of the genes related to metabolism in rats / 中国结合医学杂志

<p><b>OBJECTIVE</b>To study the influence of Radix aconiti lateralis preparata and Rhizoma zingiberis, two species of Chinese medicinal herbs with hot property, on energy metabolism and gene expression spectrum, and to analyze the possible mechanism of their effects.</p><p><b>METHODS</b>Forty-eight specific pathogen free Wistar rats were randomly divided into a Radix aconiti lateralis preparata group, a Rhizoma zingiberis group, and a control group. They were intragastrically treated with concentrated decoction of Radix aconiti lateralis preparata, Rhizoma zingiberis and normal saline respectively for 20 days. Toe temperature (TT), energy intake (EI), digestible energy (DE), and metabolizable energy (ME) were measured. The content of adenosine triphosphate (ATP) and energy charge (EC) in hepatic tissue were measured with high performance liquid chromatography (HPLC). The activity of ATPase and succinate dehydrogenase (SDH) in the liver were detected with chemical colorimetry. The gene expression in the liver was detected with Illumina's rat Ref-12 gene array. The differential expression genes were selected, annotated and classified based on Gene Ontology (GO). Real-time quantitative reverse-transcriptase PCR (Q-RT-PCR) was used to test the accuracy of results.</p><p><b>RESULTS</b>Compared with the control group, the TT on the 10(th) day after the beginning of administration and ATP in the Radix aconiti lateralis preparata and Rhizoma zingiberis groups increased significantly (P<0.05). EI/body mass (BM), DE/BM, ME/BM, the hepatic EC and the activity of Na(+)-K(+)-ATPase, Ca(2+)-Mg(2+)-ATPase and SDH of liver increased significantly only in the Radix aconiti lateralis preparata group (P<0.05). There were 592 differential expression genes in the Radix aconiti lateralis preparata group and 1 159 in the Rhizoma zingiberis group compared with the control group. Among the differential expression genes, genes related to metabolic processes were the most significant based on GO analysis. There were 337 strips of gene differential expression in common in both Radix aconiti lateralis preparata and Rhizoma zingiberis groups compared with the control group.</p><p><b>CONCLUSIONS</b>Herbs with hot property such as Radix aconiti lateralis preparata and Rhizoma zingiberis could improve the energy metabolism in rats, through influencing the metabolic process of sugar, lipid, and amino acid. It could also promote the production, storage, and utilization of energy by regulating the gene expression related to metabolism, which may be the main molecular mechanism of warming yang and dispelling cold for the treatment of the cold syndrome according to Chinese medicine theory.</p>
