ABSTRACT

Lancang-Mekong Cooperation is a new type of subregional cooperation mechanism initiated and built by China and other five countries of the Lancang-Mekong subregion, namely Laos, Myanmar, Thailand, Cambodia, and Vietnam. Countries in the Lancang-Mekong subregion are geographically and culturally connected, and they have nurtured their unique traditional medicine. By combing the history of traditional medicine exchanges between China and other Lancang-Mekong countries and their progress of modern research, this paper summarized the challenges and opportunities of traditional medicine cooperation in the Lancang-Mekong subregion. It has been found that many regional cooperation mechanisms coexist for a long time in the Lancang-Mekong subregion and the medicinal resources are abundant. However, the degree of their development and utilization varies, and modern scientific research is insufficient. Lancang-Mekong Cooperation has provided a strong support for integrating the advantageous resources in Lancang-Mekong subregion countries and making progress together. Focusing on the development and protection of medicinal resources, this paper puts forward a new path of cooperation in the intellectual property rights and characteristic seed resource protection, the compilation of universal herbal pharmacopoeia in various countries, the research and development of public health products, and the construction of traditional herbal industry bases, thus enabling the traditional medicine to better protect the public health and building a human health community.

ABSTRACT

High fat diet induced hyperlipidemia hamster model was used to explore the anti-hyperlipidemia effect of water extract of Moringa oleifera leaves( WEMOL). On this basis,the possible action mechanism was predicted by network pharmacology. Golden hamsters were randomly divided into normal diet group( NFD),high-fat diet group( HFD),simvastatin group,high dose group of WEMOL( HIWEMOL) and low dose group of WEMOL( LOWEMOL). The model was administered simultaneously for 66 days,during which the body weight changes of hamsters were recorded. At the end of the experiment,serum lipid level and serum transaminase level of golden hamsters in each group were detected,and the pathological changes of liver were observed by hematoxylin-eosin( HE) staining. The results showed that WEMOL could significantly decrease the serum total cholesterol( TC),total triglyceride( TG),low density lipoprotein cholesterol( LDL-c) levels,and reduce the lipid deposition in liver tissue,thus improving the hyperlipidemia of golden hamsters. According to the prediction of network pharmacology,219 targets of potential active components of M.oleifera leaves and 185 targets of water-soluble potential active components of M. oleifera leaves for the treatment of hyperlipidemia were obtained separately. The MCODE analysis was performed on the PPI network of 219 targets and 185 targets obtained above and got five and four clusters respectively. The signaling pathway analysis of clusters showed that among the common pathways,nonalcoholic fatty liver,insulin resistance,MAPK signaling pathway,estrogen signaling pathway,cell apoptosis and HIF-1 signaling pathway were associated with hyperlipidemia. In addition,the potential active components of M. oleifera leaves could also inhibit the metabolic inflammation of hyperlipidemia by modulating complement and coagulation cascades signaling pathway,and GSK3 B,F2,AKT1,RELA,SERPINE1 might be the key targets. The water-soluble potential active components of M. oliefera leaves could modulate lipid metabolism by modulating AMPK signaling pathway and JAK-STAT signaling pathway,with PIK3 CB,PIK3 CA,CASP3,AKT1 and BCL2 as the key targets. These results suggested that WEMOL had anti hyperlipidemia effect,and its mechanism might be related to the protein expression regulation of lipid metabolism,nonalcoholic fatty liver disease and atherosclerosis related signaling pathways.

ABSTRACT

Chinese materia medica( CMM) serves as an important cornerstone for the development of traditional Chinese medicine( TCM) culture and industry due to its unique ecological,medical,economic,scientific and technological,and cultural values. The supply shortage and unstable quality of some CMM resources have hindered the development of TCM. Ensuring the sustainable use of CMM resources has become essential for the development of TCM in China. Enriching CMM resources is the key to ensuring the sustainable utilization of TCM resources in China,which can be achieved via expanding the medicinal parts,developing the substitutes,seeking for analogues,exploring the ethnic and folk medicines,or introducing foreign medicinal materials. CMM efficacy or function positioning plays a very important role in the transformation of new CMM resources. The strategies and methods for efficacy or function positioning of new CMM resources,including analogy,plant genetic relationship exploration,medicinal property deduction,ethnobotanical investigation,text mining,network pharmacology,and structure-activity relationship exploration,were systematically proposed in this study based on CMM theory,textual research,and modern methodologies. This paper is expected to provide a theoretical reference for the continuous enrichment and development of CMM resources and the high-quality development of TCM culture and industry.

ABSTRACT

To explore the potential molecular mechanism of Mongolian medicine Bawei Sanxiang San in the treatment of chronic heart failure(CHF) through network pharmacology and molecular docking technology. The active ingredients and potential targets of Bawei Sanxiang San were collected by applying TCMSP, BATMAN databases and literature mining. CHF-related genes were collected through TTD, GeneCards and CTD databases. After the potential common targets between Bawei Sanxiang San and CHF were disco-vered, the interaction network diagram of "compound-target-pathway" was constructed using Cytoscape. The intersecting targets were imported into the DAVID database for GO function and KEGG pathway enrichment analysis. Finally, the Autodock_vina software was used to molecularly dock the selected proteins with the active ingredients of Bawei Sanxiang San. The results showed that there were 60 active ingredients in Bawei Sanxiang San that might be used to treat CHF, involving 311 target genes and 7 signaling pathways that directly related to CHF, such as HIF-1 signaling pathway, TNF signaling pathway, adrenergic signaling in cardiomyocytes, aldosterone-regulated sodium reabsorption, calcium signaling pathway, cGMP-PKG signaling pathway, renin secretion. Additionally, molecular docking showed that the bioactive compounds had good binding activity with the protein receptors of key target genes. Bawei Sanxiang San might exert therapeutic effects on CHF by regulating cardiomyocytes, angiogenic and inflammation related targets and pathways in a multi-component, multi-target and multi-pathway manner.

ABSTRACT

OBJECTIVES@#The proliferation, migration capacity, and expression of activation-related proteins of NHGFs+Cal27-exo were determined by coculturing Cal27 exosome (Cal27-exo) with normal human gingival fibroblasts (NHGFs) to explore the effects of Cal27-exo on the activation and biological behavior of NHGFs.@*METHODS@#Cal27-exo was extracted using supercentrifugation, and exosomes were identified using Western blot, transmission electron microscopy (TEM), and particle size detection. Cal27-exo was cocultured with NHGFs to detect the uptake of Cal27-exo by NHGFs, and the proliferation and migration capacity of NHGFs+Cal27-exo were detected using CCK8 and wound healing tests, respectively. The expression levels of NHGF activation-related proteins, i.e., matrix metalloproteinase-9 (MMP-9), fibroblast-activating protein (FAP), alpha smooth muscle actin (αSMA), and transforming growth factor-β (TGF-β), were detected using real-time quantitative polymerase chain reaction (qRT-PCR).@*RESULTS@#Cal27-exo was extracted u-sing supercentrifugation, and Western blot showed the positive expression levels of Alix and CD63. TEM showed that Cal27-exo had a circular double-layer vesicle. The particle size was between 30 and 150 nm. Cal27-exo labeled with PKH67 entered NHGFs after the coculture method. The wound healing test showed that the migration capacity of NHGFs+Cal27-exo was stronger after the scratch compared with that of NHGFs. CCK8 results showed that the proliferation activity of NHGFs+Cal27-exo was enhanced. qRT-PCR results showed that the MMP-9 levels of NHGFs+Cal27-exo were upregulated, whereas the TGF-β and αSMA mRNA levels of NHGFs+Cal27-exo were downregulated (@*CONCLUSIONS@#The proliferation and migration ability of NHGFs+Cal27-exo are enhanced, and the mRNA expression of related proteins is changed. Cal27-exo can activate NHGFs, which suggests that Cal27-exo has potential significance in tumor invasion and metastasis.

ABSTRACT

In December 2019, an outbreak of viral pneumonia began in Wuhan, Hubei Province, which caused the spread of infectious pneumonia to a certain extent in China and neighboring countries and regions, and triggered the epidemic crisis. The coronavirus disease 2019(COVID-19) is an acute respiratory infectious disease listed as a B infectious disease, which is managed according to standards for A infectious disease. Traditional Chinese medicine and integrated traditional Chinese and Western medicine have played an active role in the prevention and control of this epidemic. China's ethnomedicine has recognized infectious diseases since ancient times, and formed a medical system including theory, therapies, formula and herbal medicines for such diseases. Since the outbreak of the COVID-19 epidemic, Tibet Autonomous Region, Qinghai Province, Inner Mongolia Autonomous Region, Xinjiang Uygur Autonomous Region and Chuxiong Autonomous Prefecture of Yunnan, Qiandongnan Autonomous Prefecture of Guizhou have issued the prevention and control programs for COVID-19 using Tibetan, Mongolian, Uygur, Yi and Miao medicines. These programs reflect the wisdom of ethnomedicine in preventing and treating diseases, which have successfully extracted prescriptions and preventive measures for the outbreak of the epidemic from their own medical theories and traditional experiences. In this paper, we summarized and explained the prescriptions and medicinal materials of ethnomedicine in these programs, and the origin of Tibetan medicine prescriptions and Mongolian medicine prescriptions in ancient books were studied. These become the common characteristics of medical prevention and treatment programs for ethnomedicine to formulate therapeutic programs under the guidance of traditional medicine theories, recommend prescriptions and prevention and treatment methods with characteristics of ethnomedicine, and focus on the conve-nience and standardization. However, strengthening the support of science and technology and the popularization to the public, and improving the participation of ethnomedicine in national public health services and the capacity-building to deal with sudden and critical diseases are key contents in the development of ethnomedicine in the future.

ABSTRACT

The medication rules of high frequency herb-pairs containing Codonopsis pilosula (Dangshen) were analyzed with data mining tools, and the molecular mechanisms of these herb-pairs on the gastrointestinal diseases were predicted with the network pharmacology. The R language association rules were used to mine the high frequency herb-pairs from TCM formulae containing Dangshen, and these herb-pairs would be screened out, which satisfied the following requirements with support ≥ 0.3 and confidence ≥ 0.9 at the same time. Using the Integrated Pharmacology Platform of Traditional Chinese Medicine (TCMIP) to predict the key core targets of the high frequency herb-pairs, the network of Chinese medicine-compound-target-pathway related to Dangshen were built to explore the preventing and treating molecular mechanism on gastrointestinal diseases. At last, the relation of the main active components from Dangshen and its herbal pairs with target proteins were validated by Systems Dock Web Site. The 185 formulae were selected from 543 formulae containing Dangshen, and 6 herbal pairs with Dangshen, which includes Angelica (Danggui), Licorice (Gancao), Atractylodes macrocephala (Baizhu), Poria cocos (Fuling), dried tangerine peel (Chenpi) and Astragalus membranaceus (Huangqi), were discovered with Apriori algorithm. The combination of 6 herbal pairs is similar to Bu Zhong Yi Qi Decoction; 6 herbal pairs with Dangshen were related to the target of POMC, OPRM1, CCR9 and HTR2C in TCMIP. The known targets (HTR2C, POMC, OPRM1, CCR9, OPRD1) and potential drug-targets (GNB1, GCK, SDHD, SLC25A2, DHRS4) for gastrointestinal diseases were predicted about the high frequency pairs with Dangshen. The results of GO enrichment analysis showed that the biological function was mainly located in the mitochondria and myelin sheath, and involved in the biological processes of three carboxylic acid cycle, platelet activation, and aspartic acid metabolism. KEGG pathway enrichment analysis showed that the main metabolic pathways related with Dangshen pairs involved amino acid metabolism, energy metabolism and endocrine metabolism. The prediction results showed many targets of the frequency herbal pairs with Dangshen preventing and treating gastrointestinal diseases were related with nerve cells. These herbal pairs could prevent and treat the gastrointestinal diseases through the neuroendocrine system and the brain gut axis.

ABSTRACT

Based on the fact that chromogenic reaction of blue complex, a reaction product which can be dissolved in organic solvents, can be realized by polyethoxy and ammonium thiocyanate in tween 80, a rapid and accurate way for the determination for tween 80 in pharmaceutical adjuvant was established in this study, providing reliable technical means for quality control of traditional Chinese medicine injections. Based on the study of reaction kinetics, chromogenic reaction temperature and time, as well as extraction of organic solvents and other key conditions were optimized, and Kumu injection was used as the test material for method validation and applicability investigation. It was finally determined that 3 mL ammonium thiocyanate solution was added in the sample solution, and the reaction was carried out in a boiling water bath for 2 h. After cooling to room temperature, 5 mL of dichloromethane was added to extract the chromogenic product. The absorbance value was measured at the wavelength of 623 nm to calculate the tween 80 content in the sample. Under optimized conditions, tween 80 solution showed a good linear relationship with the absorbance in the range from 0.8 mg to 3.0 mg. The linear regression equation was =0.258-0.047. The correlation coefficient was 0.999 6. Under the experimental conditions, the average recovery was 99.66%, and the precision RSD was less than 2.0%. The results showed that this method can quickly and accurately determine the content of tween 80 in Kumu injection, and it could be applicable to the quality control of traditional Chinese medicine injections.
