Chemical components and pharmacological action of Aconiti Radix / 中国中药杂志

Aconiti Radix is a commonly used traditional Chinese medicine( TCM) herb in clinic,with the effects in expelling wind and removing damness,warming menstruation and relieving pain. With a long medicinal history and high medicinal value,it was used for anemofrigid-damp arthralgia,arthralgia,cold hernia and anesthesia analgesia. Modern pharmacological studies have shown that Aconiti Radix has a good therapeutic effect on rheumatoid arthritis,neuropathic pain and hypertension. As a well-known toxic TCM herb,its main pharmacodynamic and toxic components are alkaloids,which can lead to neurotoxicity and cardiotoxicity while exerting anti-inflammatory,analgesic,anti-tumor and other pharmacodynamic effects. Therefore,it is often processed to reduce its toxicity or combined with Paeoniae Radix Alba and Stephaniae Tetrandrae Radix to achieve the purpose of reducing toxicity and increasing efficacy in clinic.In recent years,with the deepening of the study on the incompatibility of TCM represented by " eighteen incompatible herbs",there have been new findings about TCM incompatibility. It has been found complementary effect,rather than no obvious toxic and side effects after the combination with incompatible herbs of Aconiti Radix. To provide the basis for further study and clinical application of Aconiti Radix,this paper reviewed chemical components,pharmacological action,toxicity and compatibility of Aconiti Radix by consulting relevant literatures published in recent years at home and abroad. Meanwhile,this paper also described the relationship between chemical constituents,as well as anti-inflammatory,analgesic,anti-tumor and other pharmacological effects and toxicity.

Name standardization and variety arrangement of Chinese national "Qi medicinal herbs" based on VFP / 中国中药杂志

"Qi medicinal herbs" in China refers to a kind of regional national folk herbs related to the treatment of five labors and seven injuries,the last word of which is "Qi". Our study is to sort out and standardize the name and basic confused varieties through the establishment of " Qi medicinal herbs" VFP information database. " Qi medicinal herbs" variety sorting model of " literature research-variety survey-data mining-spatial distribution" was developed by means of literature analysis which the names and varieties of " Qi medicinal herbs" in the literature were summarized and sorted out. The relationship between the distribution of " Qi medicinal herbs" resources and the use of ethnic groups were visualized by Cytoscape 2. 8. 0 software. The information database of " Qi medicinal herbs" involved in 230 kinds of medicinal materials which including 211 species of plants( including varieties) from 66 families. Medicinal materials standard in China have 9 kinds of " Qi medicinal herbs". Among them,there are 31 kinds of " Qi medicinal herbs" with the confusion of " the different names of the same" and " the different substance of the same names". The most used ethnic groups are Tujia,Qiang and Miao. The main efficacy is clearing heat and detoxification,dispelling wind and removing dampness,etc.,and the main treatment is for injury,rheumatic arthralgia and so on. Names and varieties of " Qi medicinal herbs" among Chinese ethnic groups and folk are standardized and sorted out,which is served to promotethe " Qi medicinal herbs" reasonable protection and utilization of resources,and provide effective reference for exploring the information technology and geographical distribution of ethnic medicine and standardizing clinical medication.

Anti-inflammatory mechanism analysis of antirheumatic Chinese medicinal herb Aconiti Radix based on protein interaction network / 中国中药杂志

Inflammation is one of the important risk factors of rheumatic diseases. Aconiti Radix is widely used for the treatment of rheumatism, which has significant anti-inflammatory effects. However, its anti-inflammatory mechanism on molecular level is still not clear. The purpose of this study is to illuminate the anti-inflammatory mechanism of Aconiti Radix based on the protein interaction network (PIN) analysis on molecular network level. The main anti-inflammatory components (aconitine, hypaconitine and mesaconitine) were chosen in this study to obtain the targets of the components and protein-protein information though databases retrieval and construct the PIN of Aconiti Radix. By a graph theoretic clustering algorithm molecular complex detection(MCODE), 13 modules were identified and analyzed by gene ontology(GO) enrichment. The results showed that the anti-inflammatory mechanism of Aconiti Radix was mainly associated with prostanoid metabolic process and leukocyte chemotaxis mediated by chemokines. In this study, the anti-inflammatory mechanism of Aconiti Radix was elucidated systematically from molecular network level, which provided the scientific basis for the treatment of rheumatic diseases.

Anti-inflammatory mechanism research of flavonoid compounds in Dalbergiae Odoriferae Lignum by module-based network analysis / 中国中药杂志

Dalbergiae Odoriferae Lignum as a traditional Chinese medicine (TCM) has been widely used for promoting blood circulation and removing blood stasis. Flavonoid compounds are main chemical constituents of Dalbergiae Odoriferae Lignum, which exert anti-inflammatory property. However, the underlying anti-inflammatory mechanisms of flavonoid compounds are incompletely understood. It has been reported that isoliquiritigenin, liquiritigenin, naringenin and butein possess anti-inflammatory property. The purpose of this study is to illuminate the anti-inflammatory mechanism of flavonoid compounds based on the protein interaction network (PIN) analysis on molecular network level. 130 targets of the main medicinal ingredients of flavonoid compounds were gained though database retrieval. A protein interaction network of flavonoid compounds was constructed with 589 nodes and 216 interactions. By a graph theoretic clustering algorithm Molecular Complex Detection (MCODE), 26 modules were identified and analyzed by Gene ontology (GO) enrichment. Two modules were associated with anti-inflammatory actions. The most interesting finding of this study was that the anti-inflammatory effect of flavonoid compounds may be partly attributable to inhibite FOS, PTGS2 expression, inhibite of IL-1beta release, and block the MAPK pathway and toll-like receptor pathway.
