Study on the objectivity and biological mechanism of Psoralea corylifolia Linn.'s 'Great dryness damages the liver' / 药学学报

According to the theory of 'Xingben Dazao' of Psoralea corylifolia Linn. (BL), the susceptible syndromes and biomarkers of liver injury caused by BL were searched. Rat models of kidney-yin deficiency syndrome (M_yin) and kidney-yang deficiency syndrome (M_yang) were established, and all animal experimental operations and welfare following the provisions of the First Affiliated Experimental Animal Ethics and Animal Welfare Committee of Henan University of Traditional Chinese Medicine (No. YFYDW2020017). The results showed that BL significantly decreased the body weight, water intake, and urine weight of M_yin rats and increase the organ indexes of the liver, testis, adrenal gland, and spleen and the expression of alanine aminotransferase (ALT). Meantime, BL significantly increased the urine weight of M_yang rats and decreased the expression of ALT and aspartate aminotransferase (AST). Hematoxylin and eosin (HE) staining showed that BL could aggravate inflammatory infiltration of hepatocytes in rats with M_yin and alleviate liver injury in rats with M_yang. Metabolomics identified 17 BL co-regulated significant differential metabolic markers in M_yin and M_yang rats. Among them, 8 metabolites such as glutamine, quinolinate, biliverdin, and lactosylceramide showed opposite trends, mainly involving cysteine and methionine metabolism, tyrosine metabolism, tryptophan metabolism, purine metabolism, sphingolipid metabolism, glycerol phospholipid metabolism, glutamine metabolism, and other pathways. M_yin/M_yang may be the susceptible constitution of BL for liver damage or protection, which may be related to the regulation of amino acid metabolism and sphingolipid metabolism. The study can provide some experimental data support for the safe and accurate use of BL in the clinical practice of traditional Chinese medicine.

Study on alleviating effect of Glycyrrhizae Radix et Rhizoma on Psoraleae Fructus-induced liver injury based on network pharmacology and cell experiments / 中国中药杂志

This study was designed to explore the alleviating effect and mechanism of Glycyrrhizae Radix et Rhizoma against Psora-leae Fructus-induced liver injury based on network pharmacology and cell experiments. The active components of Glycyrrhizae Radix et Rhizoma and Psoraleae Fructus were first retrieved from the Encyclopedia of Traditional Chinese Medicine(ETCM), Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), Comparative Toxicogenomics Database(CTD), and literature and further screened by SwissADME. The obtained 25 potential toxic components of Psoraleae Fructus and 29 flavonoids in Glycyrrhizae Radix et Rhizoma were input into the SwissTargetPrediction for target predication. A total of 818 targets related to liver injury were screened out based on GeneCards and MalaCards, and 91 common targets of Psoraleae Fructus, Glycyrrhizae Radix et Rhizoma, and liver injury were obtained from Venny. STRING was applied for constructing the PPI network, and Metascape for analyzing the biological processes and signaling pathways that common targets participated in. Cytoscape was used to construct the component-target-disease network and component-target-pathway network for Glycyrrhizae Radix et Rhizoma against Psoraleae Fructus-induced liver injury. The predicted core targets were proto-oncogene tyrosine-protein kinase(SRC), phosphatidylinositol 4,5-bisphosphate 3-kinase subunit alpha(PIK3 CA), RAC-alpha serine/threonine-protein kinase(AKT1), etc, with PI3 K-AKT signaling pathway, MAPK signaling pathway, apoptosis, Toll-like receptor signaling pathway, and NF-κB signaling pathway mainly involved. Following the scree-ning of the main toxic and pharmacodynamic components, the pharmacodynamic effects were investigated by cell experiments. The results showed that licochalcone A was mainly responsible for alleviating coryfolin-induced liver injury, licochalcone B for coryfolin-and psoralidin-induced liver injury, and echinatin for corylifolinin-and bakuchiol-induced liver injury. The preliminary revealing of the alleviating effect of Glycyrrhizae Radix et Rhizoma on Psoraleae Fructus-induced liver injury and the prediction of related mechanisms will provide reference for further mechanism research and reasonable clinical compatibility.

Advances in Study of Chinese Medicine on Prevention and Treatment of Immune Response to Chronic Obstructive Pulmonary Disease / 中国实验方剂学杂志

Chronic obstructive pulmonary disease (COPD), as a common respiratory disease characterized by progressive development, not only has the incidence increased year by year, but also has a high disability and mortality rate, which brings serious economic burden to patients. Immune response plays an important role in the pathogenesis of COPD. Studies have shown that COPD is closely related to the disorder of autoimmune function, and traditional Chinese medicine (TCM) interferes with the disease process of COPD by mediating immune response. This paper mainly contains four kinds of research contents of TCM intervention on COPD immune response, namely T lymphocyte subsets count, immunoglobulin count, Th17/Treg dynamic balance, Th1/Th2 dynamic balance and related signaling pathways. In order to provide new reference and ideas for experimental research, a brief review is made at the end of this paper.

Relationship Between Rotavirus and TLRs and Research Progress of Traditional Chinese Medicine / 中国实验方剂学杂志

Rotavirus (RV) infection of human body is mainly colonized in human intestinal epithelial cells, which results in small intestinal epithelial cell damage, and then induces diarrhea, fever and other symptoms. It is one of the most common causes of infantile diarrhea. Toll-like receptors (TLRs), as a kind of pattern recognition receptors, play an important role in the host immune system after virus infection. After different viruses infect human body, various pathogens trigger the host immune response through TLRs, induce the release of various cytokines, and stimulate a series of inflammatory reactions, such as fever, cough and diarrhea, which may further lead to more serious adverse consequences. According to the findings, the anti-inflammatory and anti-viral mechanisms of various effective drugs developed for different pathogens may be closely related to the intervention of TLRs signaling pathway and the regulation of immune response. A large number of studies have shown that rotavirus infection can induce inflammation by affecting the expressions of related proteins and genes in Toll-like receptor 3 (TLR3) and Toll-like receptor 4 (TLR4) signal transduction pathways, stimulating the release of inflammatory cytokines and inducing inflammatory response. Some studies on the mechanism of drug treatment for rotavirus diarrhea also started with TLRs, but only a few clinical and experimental studies on traditional Chinese medicine(TCM) and rotavirus diarrhea involve TLRs signaling pathway. Therefore, this article will focus on the relationship between TLRs signaling pathway and different viral infections, especially with rotavirus infection, in three aspects:viral infection and TLRs signaling pathway, RV infection and TLRs signaling pathway, and the research of traditional Chinese medicine in the treatment of rotavirus diarrhea, in order to guide the clinical and experimental studies on the treatment of rotavirus diarrhea with TCM based on TLR3 and TLR4 signaling pathways.

Screening of serum susceptibility biomarkers in patients with mild liver function abnormalities based on non-targeted metabolomics / 中国中药杂志

In the present study,non-targeted metabolomics technique was used to screen potentially susceptibility biomarkers in patients with mild liver function abnormalities during long-term use of Chinese herbal compound. According to the inclusion and exclusion criteria,we collected 7 cases of patients with abnormal liver function during the period of complete taking Chinese herbal medicine( 60 days),and 18 cases of patients with normal liver function in re-examination from the reproductive medicine center in our hospital. Ultra performance liquid chromatography coupled with time-of-flight mass spectrometry( UPLC-Q-TOF/MS~E) technique combined with Progenesis QI software was used to analyze the differential biomarkers in serum of patients with wild liver function abnormalities and normal liver function. 11 potential biomarkers such as bilirubin,pantothenic acid,hippuric acid,sphingomyelin,palmitic acid,and oleic acid were tentatively identified. Metabolic disorders in patients with herbal-induced mild liver abnormality were mainly related to two pathways: pantothenic acid and coenzyme A biosynthesis and linoleic acid metabolism. It could provide a reference for the early warning of mild liver function abnormalities of patients that may be caused by long-term use of Chinese medicine compound in clinical application,and will lay a foundation for further understanding the endogenous substance changes in different levels of liver injury.

Signal Pathways Relating to Prevention and Treatment of Airway Remodeling in Chronic Obstructive Pulmonary Disease with Traditional Chinese Medicine / 中国实验方剂学杂志

Chronic obstructive pulmonary disease (COPD) is a common respiratory disease with a high morbidity, disability and mortality. At the same time, COPD is always accompanied by pulmonary hypertension, pulmonary fibrosis, chronic pulmonary heart disease, right heart failure and other common serious complications. All of these cause serious financial burden for the family of patients. Airway remodeling plays an important role in the pathogenesis of COPD. It is the progressive development of airflow restriction that induces the main symptoms of COPD, such as cough, asthma and depression. Therefore, it is of great research value to explore the intervention of traditional Chinese medicine(TCM) in the development of COPD by alleviating airway remodeling. Studies have shown that multiple signaling pathways can induce progressive airway remodeling, and the therapeutic effect of TCM has been frequently confirmed by experimental studies. TCM often has a therapeutic effect on COPD through multi-target and multi-channel mediation. This paper mainly includes five signaling pathways that traditional Chinese medicine can intervene COPD airway remodeling, namely matrix metalloproteinases (MMPs)/tissue inhibitors of metalloproteinase (TIMPs), transforming growth factor (TGF)-beta 1/Smads, RhoA/Rho-associated kinase (ROCK), vascular endothelial growth factor (VEGF)/b-fibroblast growth factor (b-FGF) and nuclear factor (NF)-κB. This paper briefly reviews the research progress of these five signaling pathways, and discusses other signaling pathways that may be involved, in order to provide reference and ideas for future experimental research.

Comparative study of main components of ginseng on immune function of rats / 中国中药杂志

Ginseng and its effective components are famous for their influence to enhance human immunity, regulate endocrine and antioxidant action. However, the different effects of different components are not clear. In this study, Wistar rats were used to study the effects of main components of ginseng, including total ginsenoside, panaxadiol saponins, panaxtrol saponin and ginseng polysaccharide. The results showed that the effects of panaxadiol saponins and ginseng polysaccharide on improving animal immune organ weight, plasma interleukin 2 (IL-2), interleukin 6 (IL-6), plasma gamma-interferon (IFN-γ), tumor necrosis factor alpha (TNF-α) were better than that of the other groups. Total ginsenoside and panaxtrol saponin can effectively increase the concentration of spleen NK cells (NKC) while panaxadiol saponins and ginseng polysaccharide can significantly increase the concentrations of rat plasma adrenocorticotrophic hormone (ACTH), corticosterone (CORT) and thyroid stimulating hormone (TSH). As for the effect of increasing organization nitric oxide (NO) and superoxide dismutase (SOD), glutathione (GSH) and malondialdehyde (MDA), total ginsenoside is better than that of other groups. In brief, different components in ginseng possess different effects on enhancing immunity, regulating endocrine and resisting oxidation. Panaxadiol saponins and ginseng polysaccharide are better in enhancing immune, and total ginsenoside shows advantages in resisting oxidation and stress.

Urine metabonomic study on long-term use of total ginsenosides in rats / 中国中药杂志

Due to its effect of systems regulation and promotion on body, Ginseng is always referred to be long-term used as a dietary supplement. But it was still unclear about its target of the tonic effects and also the side-effects long-term use may bring. Urine metabolomic method is suitable for long-term studies of pharmaco-dynamics, pharmacology and toxicology of traditional Chinese medicine because of its characteristics of non-invasive and monitoring the whole-body metabolism. This study was designed to detect the dynamic variation of rat urine metabolome along with a long-term administration of total ginsenosides using GC-TOF based metabolomic technology. Our result showed that either short-term or chronic administration of ginsenosides did not impact the rat urine metabolome significantly (as the PCA subgroup was not successful). By comparison, the short-term (1-3 w) dose of ginsenosides had the biggest metabolic influence including TCA cycle, catecholamines and neurotransmitter amino acids. Medium-term (6-10 w) dose had a gradually lower effect and long-term (27 w) dose almost had no effect. Our study indicates that both short and long-term administration of ginsenosides showed almost no obvious side-effect on the experimental animals.
