Etiology and Chinese Medicine Screening of Severe COVID-19 Based on Multiomics and Serum Pharmacology

Background At present, scholars believe that severe COVID-19 is related to a variety of basic diseases, and we also observe this point using multi-omics method. The latest sequencing data of severe COVID-19 patients were combined to analyze the pathological mechanism, and pharmacological experimental research on local drugs was conducted, and a compound ingredient was found to have potential medicinal value. Results Here, we observed, for patients with severe COVID-19 disease, the differential miRNA expression is mainly low but having higher expression of mRNA. These differential mRNA expressions are associated with the activation of inflammatory pathways and ultimately with hypoxia and coagulation. Using database analysis, we found that Yi Xin Tong Mai Granule(YXTMG) might regulate COVID-19 through Toll-like receptor signaling pathway by acting on different immune targets. We found a new molecular mechanism for COVID-19 to turn the crisis around, the down-regulated miR-181a-5p mediates the up-regulation of PLAU and SERPINE1 molecules to cause cardiovascular adverse events, and YXTMG may prevent it. At the same time, molecular docking indicated that the its various components have anti-inflammatory activity. In vitro studies, we confirmed that YXTMG had antioxidant and anti-inflammatory activities. Conclusions The study has supplemented the potential mechanism for the conversion of mild to critical COVID-19 disease and screened the Chinese medicines for improving these factors, providing methodological reference for disease pathology and drug development.

A Characterization Study to Indetify Antibactrial Effect of Ruta Graveolens (Hurb of Grace)

Most of rural people even today depend on plants for medicines. The use of complentary and alternative medicine (CAM) has become increasingly popular worldwide, such that an estimated 38% of American adults reported using a form of CAM in 2006. The study of herbal remedies is common because many diseases and infections are known to have been treated with natural medicinal plants throughout the history of humanity. Ruta graveolens is aromatic shrub belong to family rutaceae and is commonly known as rue, cultivated as ornamental and medicinal herb in gardens. Due to its cultural and medicinal value, rue has been introduced in various countries of North, Central and South America, China, India, Middle East and South Africa. This plant also contains glucoside rutin. The flavonoids are a part of primary chemical components of Ruta graveolens Linn. The most important analyzed flavonoids are rutin (quercetin-3-β- rutinoside) that belongs to flavonol glycoside. Quercetin is other major flavonoids found in Ruta graveolens and can also be obtained by rutin hydrolysis.

Integrative Analysis of the Transcriptome and Metabolome Reveals the Mechanism of Saline–Alkali Stress Tolerance in Astragalus membranaceus (Fisch) Bge. var. mongholicus (Bge.) Hsiao

Saline–alkali stress is a major abiotic stress affecting the quality and yield of crops. Astragalus membranaceus (Fisch) Bge. var. mongholicus (Bge.) Hsiao (A. mongholicus) is a well-known medicine food homology species with various pharmacological effects and health benefits that can grow well in saline–alkali soil. However, the molecular mechanisms underlying the adaptation of A. mongholicus plants to saline–alkali stress have not yet been clarified. Here, A. mongholicus plants were exposed to long-term saline–alkali stress (200 mmol·L -1 mixed saline–alkali solution), which limited the growth of A. mongholicus. The roots of A. mongholicus could resist long-term saline–alkali stress by increasing the activity of antioxidant enzymes and the content of osmolytes. Transcriptome analysis (via the Illumina platform) and metabolome analysis (via the Nexera UPLC Series QE Liquid Mass Coupling System) revealed that saline–alkali stress altered the activity of various metabolic pathways (e.g., amino acid metabolism, carbohydrate metabolism, lipid metabolism, and biosynthesis of other secondary metabolites). A total of 3,690 differentially expressed genes (DEGs) and 997 differentially accumulated metabolites (DAMs) were identified in A. mongholicus roots under saline–alkali stress, and flavonoid-related DEGs and DAMs were significantly up-regulated. Pearson correlation analysis revealed significant correlations between DEGs and DAMs related to flavonoid metabolism. MYB transcription factors might also contribute to the regulation of flavonoid biosynthesis. Overall, the results indicate that A. mongholicus plants adapt to saline–alkali stress by up-regulating the biosynthesis of flavonoids, which enhances the medicinal value of A. mongholicus.

The Genetic Diversity of Enset (Ensete ventricosum) Landraces Used in Traditional Medicine Is Similar to the Diversity Found in Non-medicinal Landraces

Enset (Ensete ventricosum) is a multipurpose crop extensively cultivated in southern and southwestern Ethiopia for human food, animal feed, and fiber. It has immense contributions to the food security and rural livelihoods of 20 million people. Several distinct enset landraces are cultivated for their uses in traditional medicine. These landraces are vulnerable to various human-related activities and environmental constraints. The genetic diversity among the landraces is not verified to plan conservation strategy. Moreover, it is currently unknown whether medicinal landraces are genetically differentiated from other landraces. Here, we characterize the genetic diversity of medicinal enset landraces to support effective conservation and utilization of their diversity. We evaluated the genetic diversity of 51 enset landraces, of which 38 have reported medicinal value. A total of 38 alleles across the 15 simple sequence repeat (SSR) loci and a moderate level of genetic diversity (He = 0.47) were detected. Analysis of molecular variation (AMOVA) revealed that only 2.4% of the total genetic variation was contributed by variation among the medicinal and non-medicinal groups of landraces, with an FST of 0.024. A neighbor-joining tree showed four separate clusters with no correlation to the use-values of the landraces. Except for two, all “medicinal” landraces with distinct vernacular names were found to be genetically different, showing that vernacular names are a good indicator of genetic distinctiveness in these specific groups of landraces. The discriminant analysis of the principal components also confirmed the absence of distinct clustering between the two groups. We found that enset landraces were clustered irrespective of their use-value, showing no evidence for genetic differentiation between the enset grown for ‘medicinal’ uses and non-medicinal landraces. This suggests that enset medicinal properties may be restricted to a more limited number of genotypes, might have resulted from the interaction of genotype with the environment or management practice, or partly misreported. The study provides baseline information that promotes further investigations in exploiting the medicinal value of these specific landraces.

Ethnobotanical study on plants used to dye traditional costumes by the Baiku Yao nationality of China

Background The Baiku Yao is a branch of the Yao nationality in China. The unique dying process of traditional clothing employed by these people has distinct national characteristics, a profound impact on the production and life of local people, and important research value. For this reason, it is important to investigate and document the dyeing plants and the traditional knowledge involved in the dyeing of Baku Yao traditional clothing. Methodology Information on dyeing plants was obtained using the free-list method and interviews with 61 Baiku Yao informants in Guangxi and Guizhou from January 2020 to August 2021. Based on the free-list method, we evaluated and screened out important plants by calculating the cognitive salience value of each plant. Results The results showed that the people of Baiku Yao have accumulated rich traditional knowledge of dyeing plants and long-term dyeing and other processes. We collected 23 species and recorded the related traditional knowledge, such as the Baiku Yao name, life form, habitat, part(s) used, application type, usage, and area used. The utilization of dyeing plants has a strong relationship with ethnic culture. The Baiku Yao uses unique anti-dyeing material (Ailanthus vilmoriniana) in the cotton dyeing process, they call it “the mother tree”. As well as, the results also showed that 15 plants (65.2%) have medicinal value and can be used to treat 18 aliments, and wild plants play a very important role in the life of the Baiku Yao. Conclusion These plants not only meet the color needs of the Baiku Yao people but also have health care effects, aligning with the trends toward green dyeing and the health contentiousness of modern people. This study provides a reference for the inheritance and development of Baiku Yao traditional clothing dyeing culture, will aid the identification of new natural, safe and healthy textile dyes, and is of positive significance in promoting regional economic development, national cultural inheritance, and biodiversity protection.
