Dao-di herbs, which are widely recognized as medicinal materials with a high quality and good efficacy in clinic, are now facing the dilemma of absence of standard. This study focused on a pivotal scientific problem of design and application of quality standard of Dao-di herbs, and systematically illustrated the general rules for the quality standard of Dao-di herbs involving "four rules, six core contents, and three key methods". The quality standard of Dao-di herbs shall be fully based on literatures as well as habitat, planting/breeding, processing, characters, chemical-pharmacological/toxic data. The common requirements for the quality standard of Dao-di herbs contain "clear source, explicit origin, rational indicator, gradable quality, and multiple detection methods". Notably, traditional experiences and modern techniques, quality tracing management system, "quality determination by distinguishing characters" method, rapid detection technology, effective/toxic substances control method, were comprehensively applied in this standard to purse the objectification, automation, and intellectualization of detection technology. Appearance characters, chemical components, and bioactive parameters, unified effective/toxic indicators, quality markers, and pharmacopeial control indicators and reasonable ranges were included in rigorous quality standards for Dao-di herbs. Besides, simple grading method shall be developed to guide the implementation of "high quality-high price" policy. Eventually, the new quality standards for Dao-di herbs will lead international standards and promote the high-quality development of Dao-di herbs.Ben Cao Tu Jing is the earliest version of block-printed edition for herbals so far, with 933 medicinal paintings. In this paper, it analyzed the medicine paintings in the Fruit, Vegetable and Rice Sections of Ben Cao Tu Jing, as well as discussed the types of medicine paintings and relevant information when they were drawn. There are a total of 76 paintings in the fruits, vegetables and rice sections of Ben Cao Tu Jing, which can be divided into four types broken branch paintings, ground paintings, rootless plant paintings and the whole plant with root paintings. The first three paintings were similar to the paintings of Tang and Song, and the paintings of the whole plant with root can be called the type of medicine paintings with Chinese characteristics created by Ben Cao Tu Jing. selleck chemicals llc These four types of paintings had a profound impact on the later illustrations of medicinal materials, such as Lv Chan Yan Ben Cao, Jiu Huang Ben Cao, Ben Cao Pin Hui Jing Yao, Zhi Wen Ben Cao, Zhi Wu Ming Shi Tu Kao. The two types that had the greatest impact on later generations are the broken branch paintings and the whole plant with roots paintings, which had been inherited and developed in contemporary Chinese pharmacy books such as Zhong Yao Cai Pin Zhong Lun Shu and Zhong Hua Ben Cao. The paintings of the fruits, vegetables and rice sections are highly realistic and artistic, not only carrying the role of conveying medicinal knowledge, but also having unique aesthetic value. It can be inferred that the fruits, vegetables and rice sections had the participation of professional painters at least. In addition, through the highly consistent drawing styles of several sets of paintings, it is concluded that the paintings without place names were likely to be drawn uniformly by the editing team, and the local paintings may have been revised and improved by the editing team lately.Corona virus disease 2019(COVID-19) has brought untold human sufferings and economic tragedy worldwide. It causes acute myocardial injury and chronic damage of cardiovascular system, which has attracted much attention from researchers. For the immediate strategy for COVID-19, "drug repurposing" is a new opportunity for developing drugs to fight COVID-19. Artemisinin and its derivatives have a wide range of pharmacological activities. Recent studies have shown that artemisinin has clear cardiovascular protective effects. This paper summarizes the research progress on the pathogenesis the pathogenesis of COVID-19 in cardiovascular damage by 2019 novel coronavirus(2019-nCoV) virus from myocardial cell injury directly by 2019-nCoV virus,viral ligands competitively bind to ACE2 and then reduce the protective effect of ACE2 on cardiovascular disease, "cytokine storm" related myocardial damage, arrhythmia and sudden cardiac death induced by the infection and stress, myocardial injury by hypoxemia, heart damage side effects from COVID-19 drugs and summarizing the cardiovascular protective effects of artemisinin and its derivatives have activities of anti-arrhythmia, anti-myocardial ischemia, anti-atherosclerosis and plaque stabilization. Then analyzed the possible multi-pathway intervention effects of artemisinin-based drugs on multiple complications of COVID-19 based on its specific immunomodulatory effects, protective effects of tissue and organ damage and broad-spectrum antiviral effect, to provide clues for the treatment of cardiovascular complications of COVID-19, and give a new basis for the therapy of COVID-19 through "drug repurposing".To systematically evaluate the efficacy of traditional Chinese medicine(TCM) compounds combined with levodopa medicine in the treatment of Parkinson's disease(PD), and screen basic herbs to provide certain evidence-based medical proof and program for better guidance on clinical drug use. Six databases were searched to screen out the randomized controlled trial on the TCM compounds combined with levodopa medicine in the treatment of PD. Literature quality of the included studies was evaluated by improved Jadad rating scale, and the Meta-analysis was performed by RevMan 5.3 software. After the data of the basic TCM compounds involved were sorted out, the strong association rules were found by using Apriori algorithm of SPSS Modeler 18.0 software, and then the basic herbs for the treatment of PD could be picked out. A total of 20 studies were eventually included, involving 1 784 patients. Ten studies were of high-quality literature, Jadad score≥4 points. Meta-analysis showed that efficacy of TCM combined with levodopa medicine was better than levodopa medicine alone in lowering Unified Parkinson's Disease Rating Scale(UPDRS) score UPDRS Ⅰ(MD=-0.
