ABSTRACT
COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread across the globe, posing an enormous threat to public health and safety. Traditional Chinese medicine (TCM), in combination with Western medicine (WM), has made important and lasting contributions in the battle against COVID-19. In this review, updated clinical effects and potential mechanisms of TCM, presented in newly recognized three distinct phases of the disease, are summarized and discussed. By integrating the available clinical and preclinical evidence, the efficacies and underlying mechanisms of TCM on COVID-19, including the highly recommended three Chinese patent medicines and three Chinese medicine formulas, are described in a panorama. We hope that this comprehensive review not only provides a reference for health care professionals and the public to recognize the significant contributions of TCM for COVID-19, but also serves as an evidence-based in-depth summary and analysis to facilitate understanding the true scientific value of TCM.
ABSTRACT
Objective:To investigate the mechanism of Sinisan in treating type 2 diabetes mellitus（T2DM） based on network pharmacology. Method:Based on electronic databases， active ingredients of Sinisan and target genes of ingredients as well as type 2 diabetes were screened out. Cytoscape software was applied to construct "herb-active ingredient-target-disease" interaction network diagram，respectively. The common genes of ingredients and disease were uploaded to the STRING database， and the protein interaction network map （PPI） was constructed. CytoNCA and Cluster Marker were used to analyze PPI，respectively. Finally，ClueGO was used to analyze gene ontology （GO） enrichment and Kyoto Encyclopedia of genes and genomes （KEGG） pathway enrichment. Result:A total of 137 active components and 110 effective genes of Sinisan in the treatment of type 2 diabetes were screened out. Based on PPI analysis，these effective genes were divided into 4 different clusters， and 12 genes were considered as the most effective targets. GO enrichment analysis showed that cluster 1 mainly involved acute inflammatory response and acetylcholine receptor signaling pathway， cluster 2 mainly involved cellular response to steroid hormone stimulu and xenobiotic stimulus，and cluster 3 was mainly engaged in the metabolism process of protein，fatty and glucose and the response to hypoxia. KEGG analysis was highly correlated with advanced glycation end products-receptor for AGE （AGE-RAGE） pathway，apoptosis pathway，inflammatory pathway，cell cycles and various metabolic pathways. Conclusion:Sinisan has a regulatory effect in pathogenesis and prognosis of T2DM，such as inflammation，cell apoptosis and nutrition metabolism. Moreover，its potential mechanisms on diabetic angiopathies，diabetic cognitive impairment and cancers were reveal，so as to define a direction for the fundamental research of Sinisan.
ABSTRACT
Objective: Jiaotaiwan is a classic prescription in traditional Chinese medicine for insomnia. Modern clinical research has proved its anti-diabetes effect by "the same treatment for different diseases" theory, so it is necessary to study its pharmacological mechanism for anti-diabetes effect. Method: In this study, the integrative pharmacology platform of traditional Chinese medicine (TCMIP) was used to explore the potential target and mechanism of Jiaotaiwan, and construct its core target network for diabetes. Then the enrich analysis of GO and KEGG on key targets was conducted to build the visual multilayer association network of "Jiaotaiwan-active composition-core target-key pathway". Result:28 active ingredients were obtained from Jiaotaiwan in this study. Its anti-diabetes effect was relevant to 187 core targets,including 15 known disease targets such as vasopressin V2 receptor (AVPR2), receptor activity-modifying protein 1 (RAMP1), receptor activity-modifying protein 3 (RAMP3), insulin receptor (INSR), and insulin-like growth factor 1 receptor (IGF1R); as well as 71 predictive drug targets such as cyclin-dependent kinase 9 (CDK9), glucokinase (GCK), NF-kappa-B inhibitor alpha (NFKBIA), NF-kappa-B p100 subunit (NFKB2), and hypoxia inducible factor-1 alpha (HIF1A). Conclusion:The anti-diabetes mechanism of Jiaotaiwan may be associated with activation of adenylate cyclase activity, cellular response to glucagon stimulus, activation of mitogen-activated protein kinase (MAPK) activity, endocrine system, gonadotropin-releasing hormone (GnRH) signaling pathway, Chemokine signaling pathway, phosphatidylinositol 3-kinase-serine/threonine kinases (PI3K-Akt) signaling pathway and other related biological processes and pathways. This study provides a scientific evidence for further study of the anti-diabetes mechanism of Jiaotaiwan.
ABSTRACT
Larrea divaricata Cav. (jarilla) (Zygophyllaceae) is used in Argentinean folk medicine. It contains nordihydroguaiaretic acid (NDGA), a lignan with nefrotoxic and hepatotoxic effects. The presence of NDGA converts controversial the use of L. divaricata. The amount of NDGA is higher in alcoholic extracts than in aqueous extracts (AE). The last 20 years had a great advance on the use of AE to treat different conditions in a safe manner. In this review, we present the scientific results tending to confirm the potential beneficial effects of the AE on human health. The anti-proliferative effects of AE of L. divaricata have been assayed on a tumor lymphoid line (BW 5147) and the pathways involved in such effects were described. The anti-microbial activity was determined by tests for bacteria and fungus. The anti-inflammatory activity was assayed by using carrageen and TPA induced-inflammation tests. The Immunomodulatory effects were investigated ¯in vivo and ¯in vitro on mice. Sub-fractions of aqueous extracts were obtained and analyzed. The immunogenicity of proteins from crude AE was characterized and antioxidant and nutritional activity were studied. The effect of an AE on hair loss was assayed. In summary, AE from L. divaricata has pharmacological activities including anti-microbial, anti-inflammatory, anti-cancer effects.

La presencia de NDGA hace controvertido el uso de L. divaricata. La cantidad de NDGA es mayor en extractos alcohólicos que en extractos acuosos (EA). Los últimos 20 años han tenido un gran avance en el uso de EA para el tratamiento de diferentes condiciones en forma segura. En esta revisión se presentan resultados científicos que confirman los efectos potencialmente beneficiosos de los EA sobre la salud humana. Los efectos anti-proliferativos se han ensayado en una línea de tumor linfoide, así como los mecanismos involucrados. La actividad anti-microbiana se determinó usando pruebas para bacterias y hongos. La actividad anti-inflamatoria fue evaluada mediante el uso de inflamación inducida por carragenina y TPA. Los efectos inmunomoduladores fueron investigados "in vivo" e "in vitro" en ratones. Sub-fracciones de los EA fueron obtenidos y analizados. La inmunogenicidad de las proteínas del EA crudo se caracterizaron y se estudiaron las actividades antioxidantes nutricionales. Además, se ensayó el efecto del EA en la caída del cabello. En resumen, los EA de L. divaricata presentan actividades farmacológicas como por ejemplo, anti-microbiana, anti-inflamatoria y efectos anti-cancerígenos.

Antiarrhythmic effect of isoliensinine (IL) was studied on experimental arrhythmic mo-dels induced by coronary artery ligation and 4 different arrhythmogenic drugs in comparison with quinidine(Qu). Results of the study showed that the antiarrhythmic potency of IL was stronger than that of Qu atthe same dosage. The effects of IL on fast and slow response action potentials of myocardium were ob-served in guinea pig papillary muscles by standard microelectrode technique, which showed that IL couldreduce APA and Vmax and shorten the APD50. The results suggested that the antiarrhythmic mechanismof IL is related to its non-specific inhibition of the currents of Na+ and Ca2+.
