Effects of Different Processed Methods on Anti-gouty Arthritis and Cardiotoxicity of Aconiti Radix / 中国实验方剂学杂志

Objective:To study the effects of different processing methods on the anti-gouty arthritis and cardiotoxicity of Aconiti Radix， and to explore the possible attenuation and synergism mechanism of these different processing methods. Method:The swelling degree of knee joint， levels of inflammatory factors ［interleukin （IL） -1<italic>β</italic>， IL-18， tumor necrosis factor （TNF）-<italic>α</italic>］ and the activities of liver energy metabolism-related enzymes ［Ca²⁺-Mg²⁺-adenosine triphosphatase （ATPase）， Na⁺-K⁺-ATPase， succinate dehydrogenase （SDH）］ in rats with gouty arthritis were used as indicators to evaluate the effects of pharmacopoeia steaming Aconiti Radix， pharmacopoeia boiling Aconiti Radix， Jianchang faction processed Aconiti Radix， Zhang faction processed Aconiti Radix and raw Aconiti Radix. The activity of creatine kinase （CK）， lactate dehydrogenase （LDH） and the content of B-type natriuretic peptide （BNP） were used as indexes to evaluate the cardiotoxicity of Aconiti Radix and its different processed products. Result:In the anti-gouty arthritis test， compared with the blank group， the knee joint of the model group was significantly swollen （<italic>P</italic><0.01）， the levels of IL-1<italic>β</italic>， IL-18， and TNF-<italic>α</italic> in serum were significantly increased （<italic>P</italic><0.01）， and the Ca²⁺-Mg²⁺-ATPase activity was significantly decreased （<italic>P</italic><0.01）. Compared with the model group， raw Aconiti Radix and the four processed products could reduce knee joint swelling and decrease IL-1<italic>β</italic>， IL-18， and TNF-<italic>α</italic> levels in serum of rats. The activity of Ca²⁺-Mg²⁺-ATPase in the liver of rats from the pharmacopoeia steaming Aconiti Radix group was significantly higher than that in the model group （<italic>P</italic><0.01）， and there was no statistical difference in other groups. In the cardiotoxicity test， compared with the blank group， the activities of CK and LDH were significantly increased and the level of BNP was significantly increased in the raw Aconiti Radix group and the pharmacopoeia steaming/boiling Aconiti Radix groups （<italic>P</italic><0.01）. In terms of LDH activity and BNP content， the Zhang faction and Jianchang faction processed Aconiti Radix groups were significantly lower than those in the raw Aconiti Radix group （<italic>P</italic><0.01）. In the CK activity， the Zhang faction processed Aconiti Radix group was significantly lower than that in the raw Aconiti Radix group （<italic>P</italic><0.01）. Conclusion:Raw Aconiti Radix and the four processed products have certain anti-inflammatory effects， but there are some differences among different indicators. There are significant differences in cardiotoxicity between the raw products and processed products of Aconiti Radix， and the cardiotoxicity of Jianchang faction and Zhang faction processed products was the weakest.

Research Progress on Multi-material and Multi-process Processing of Aconiti Radix / 中国实验方剂学杂志

Aconiti Radix is a kind of medicinal material with great toxicity, which has more than 2 000 years of clinical application history, in the folk, there are often poisoning accidents caused by improper processing. The main processing purpose of Aconiti Radix in the early period was to reduce the toxicity with simple procedure and single excipient. Since the Song dynasty, with the deepening of physicians' cognition of processing and the theory of medicinal properties, the application of procedures and materials in the processing of Aconiti Radix began to become complicated, and the scope of clinical application was further expanded. In modern times, the processing technology of Aconiti Radix is mainly based on steaming and boiling, which is quite different from the traditional processing method with multiple materials and multiple processes. Based on the characteristics of many kinds of materials and processes, this paper discusses the change in processing methods of Aconiti Radix from the perspective of excipients and processes, as well as modern processing research, in order to lay a scientific foundation for exploring the effects of many kinds of materials and processes on the quality of Aconiti Radix and revealing its processing mechanism, and provide basis and reference for establishing a more reasonable and scientific processing method for Aconiti Radix in the future.
