The processing of Mongolian medicine,which is called " mort harl" in Mongolian language,refers to a traditional processing technology to " tame" some toxic,aggressive,ineffective or inconvenient Mongolian medicines,so as to make it " compliant" to clinical needs. It is the summary of long-term experience in drug preparation by Mongolian medicine experts,one of the bridges for the dialectical unity of Mongolian medicine,the essential content in evaluation of the clinical efficacy of Mongolian medicine and the study of Mongolian medicine modernization,and also the important soft power carrier of " intangible cultural heritage" and " grassland culture" in Inner Mongolia autonomous region. In this study,the processing history,purpose,crafts,mechanism,processing standards and quality standards of Mongolian medicine were explained,and some suggestions were proposed for the problems of the Mongolian medicine processing and development: focus on the basic theory of Mongolian medicine and the clinical experience of Mongolian medicine in the development of traditional Mongolian medicine processing; strengthen the literature research on the processing method of Mongolian medicine; establish comprehensive and systematic Mongolian medicine concocts standards and quality standards; enhance the research and development of special processing equipment and process quality control instruments for Mongolian medicine; and strengthen the training of professional technicians,the protection of copyright in Mongolian medicine processing,and scientific research on Mongolian medicine processing. In the inheritance of the tradition,the latest achievements of modern scientific development can be also absorbed to provide reference for the further development of traditional Mongolian medicine processing technology.

This paper explores Mongolian medicine processing methods and the use regularity of excipient by text mining techniques. Relevant books of Mongolian medicine processing were consulted to collect data on Mongolian medicine processing methods and excipient, and select data based on processing methods and excipient noun frequency statistics. Microsoft Excel 2010 software was used for statistical analysis and mining for the usage regularity of different types of Mongolian medicinal materials in different periods. And Cytoscape 3.6.1 software was used for visual presentation. The topological analysis showed the top five processing methods were net production, development, frying, calcining and cooking, and the top five processing excipient were fresh milk, wine, urine, cream and mineral borax. Frequency analysis showed that the plant medicinal materials were mostly recorded in the 18~(th) and 21~(st) centuries, especially in the 21 st century; the processing methods mostly contained water processing, repair processing and other methods. The mineral medicinal materials were mostly recorded in the 18~(th), 19~(th) and 21~(st) centuries; most of the processing methods were the fire processing method. The animal medicinal materials were recorded in the 18~(th), 19~(th) and 21~(st) century; the fire processing method occupied a major position, and the repair processing and the grinding processing were markedly increased in the 21~(st) century. In the use of excipient, liquid excipient were mostly used in plant medicines. Solid excipient were most commonly used in the 18~(th) century. Animal excipient were mostly used during the processing in the 18~(th) century. The use of liquid excipient gradually increased in the 19~(th) and 21~(st) centuries. This study summarizes the traditional processing methods of Mongolian medicine and the usage regularity of excipient, defines the characteristics of Mongolian medicine processing methods and excipient, and the characteristics of the combination of medicinal materials and excipient, so as to provide reference for the clinical use of Mongolian medicine.

Inner Mongolia autonomous region of China and Mongolia are the primary regions where Chinese and Mongolian medicine and its medicinal plant resources are distributed. In this study, 133 families, 586 genera, and 1 497 species of medicinal plants in Inner Mongolia as well as 62 families, 261 genera, and 467 species of medicinal plants in Mongolia were collected through field investigation, specimen collection and identification, and literature research. And the species, geographic distribution, and influencing factors of the above medicinal plants were analyzed. The results revealed that there were more plant species utilized for medicinal reasons in Inner Mongolia than in Mongolia. Hotspots emerged in Hulunbuir, Chifeng, and Tongliao of Inner Mongolia, while there were several hotspots in Eastern province, Sukhbaatar province, Gobi Altai province, Bayankhongor province, Middle Gobi province, Kobdo province, South Gobi province, and Central province of Mongolia. The interplay of elevation and climate made a non-significant overall contribution to the diversity of plant types in Inner Mongolia and Mongolia. The contribution of each factor increased significantly when the vegetation types of Inner Mongolia and Mongolia were broadly divided into forest, grassland and desert. Thus, the distribution of medicinal plant resources and vegetation cover were jointly influenced by a variety of natural factors such as topography, climate and interactions between species, and these factors contributed to and constrained each other. This study provided reference for sustainable development and rational exploitation of medicinal plant resources in future.

Mongolians have a long history of using prescriptions, which can be classified into four stages as follows: the germination and experience accumulation stage before the 13 th century, the theoretical formation stage from the 13 th to 16 th century, the rapid development stage from the 17 th to 20 th century, and the leaping development stage from the mid-20 th century to the present. The prescriptions from the ancient classical or representative medical books have always been used by Mongolian physicians for generations, and they are still in use due to the definite curative effects. In 2008, the Notice on Issuing the Supplementary Provisions to the Registration and Management of Traditional Chinese Medicine(TCM) described that China has attached more importance to the excavation and development of classical prescriptions. As stipulated in the Law of the People's Republic of China on Traditional Chinese Medicine, the classical prescriptions should be those available in ancient TCM classics and still in wide use, with exact curative effects, distinct features, and obvious advantages. This paper expounded the historical formation and development of classical prescriptions in Mongo-lian medicine, introduced the five most influential ancient medical books revealing the formation and development of these classic prescriptions, and traced the origin of such classical prescriptions as Wenguanmu Siwei Decoction, Shouzhangshen Bawei Decoction, Jianghuang Siwei Decoction and summarized the origin, development history and characteristics of classical prescriptions in Mongolian medicine, aiming to provide a reference for their further research and development.

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.
