Résumé

Objective: “Same treatment for different diseases” is a unique treatment strategy in traditional Chinese medicine. Two kinds of malignant respiratory diseases endanger human health-chronic obstructive pulmonary disease (COPD) and lung cancer. Citrus Grandis Exocarpium (Huajuhong in Chinese, HJH), a famous herbal, is always applied by Chinese medicine practitioners to dispersion the lung to resolve phlegm based on “syndrome differentiation and treatment” theory. However, the common mechanism for HJH's treatment of COPD and lung cancer is not clear. Methods: In this study, based on network pharmacology and molecular docking technology, the common mechanism of HJH in the treatment of COPD and lung cancer was studied. The active ingredients and related targets of HJH were integrated from TCMSP, BATMAN-TAM, STP, and Pubchem databases. The standard names of these targets were united by UniProt database. Targets of COPD and lung cancer were enriched through GeneCards, NCBI (Gene), Therapeutic Target Database, and DisGeNET (v7.0) databases. Then the intersection targets of HJH and diseases were obtained. The STRING network and the Cytoscape 3.7.2 were used to construct PPI network, the DAVID database was used to perform GO and KEGG analysis. Then Cytoscape 3.6.1 was used to build “ingredient-target-signal pathway” network. Finally, AutoDock 1.5.6 software was used to perform molecular docking of key proteins and molecules. Results: Eleven active ingredients in HJH were obtained by searching the database, corresponding to 184 HJH-COPD-lung cancer targets intersection. The results of biological network analysis showed that naringenin, the active component in HJH, could mainly act on target proteins such as AKT1, EGFR. Then through positive regulation of vasoconstriction and other biological processes, naringenin could regulate estrogen signaling pathway, VEGF signaling pathway, HIF-1 signaling pathway, ErbB signaling pathway, PI3K-Akt signaling pathway to play an important role in the treatment of both COPD and lung cancer. Conclusion: Network pharmacology was employed to systematically investigate the active ingredients and targets of HJH in treatment of COPD and lung cancer. And then, the common pharmacodynamic network of HJH for the two malignant respiratory diseases was firstly described. Furthermore, naringenin was proved to strongly bind with AKT1 and EGFR. It may provide the scientific basis for understanding the “Same treatment for different diseases” strategy in traditional Chinese medicine and inspirit subsequent drug discovery for COPD, lung cancer and other malignant lung diseases.

Résumé

With the rapid aging of China's population, the incidence of hypertension has increased year by year. The lack of awareness, treatment and control is still one of the important public health problems of China. In-depth understanding of blood pressure measurement, so that residents understand their blood pressure level. It is an important part of improving residents' health literacy. Therefore, the article briefly discusses the key points of blood pressure measurement and its value for special types of hypertension.

Résumé

Schisandra chinensis, a traditional Chinese medicine (TCM), has been used to treat sleep disorders. Zebrafish sleep/wake behavioral profiling provides a high-throughput platform to screen chemicals, but has never been used to study extracts and components from TCM. In the present study, the ethanol extract of Schisandra chinensis and its two main lignin components, schisandrin and schisandrin B, were studied in zebrafish. We found that the ethanol extract had bidirectional improvement in rest and activity in zebrafish. Schisandrin and schisandrin B were both sedative and active components. We predicted that schisandrin was related to serotonin pathway and the enthanol extract of Schisandra chinensis was related to seoronin and domapine pathways using a database of zebrafish behaviors. These predictions were confirmed in experiments using Caenorhabditis elegans. In conclusion, zebrafish behavior profiling could be used as a high-throughput platform to screen neuroactive effects and predict molecular pathways of extracts and components from TCM.

Résumé

<p><b>OBJECTIVE</b>To observe the antitussive, expectorant and antiashmatic effects of the extract from Citrus grandist var. tomentosa.</p><p><b>METHOD</b>The cough models induced by ammonia liquor in mice and citric acid in guines pigs were used to observe the antitussive effects. The methods of phenel red execretion in mice and phlegm displacement of rats were used to investigate the expectorant effects. Bronchial asthma model induced by histamine-acetylcholine in guinea pigs was used to observe the antiasthmatic effects.</p><p><b>RESULT</b>The extract from the title plant could inhibit the cough induced by ammonia in mice, decrease the frequency of cough induced by citric acid in guineas pig and prolong the latent period of cough. The extract also could obviously increase phenol red output of trachea in mice, promote expectoration in rats and prolong the latent period of asthma induced by histamine-acetylcholine in guinea pigs.</p><p><b>CONCLUSION</b>The extract from C. grandis var. tomenfosa has significant antitussive, expectorant and antiasthmatic effects.</p>
