RESUMO
Danggui Liuhuangtang is the 47th of the 100 famous classical formulas published by the National Administration of Traditional Chinese Medicine， and is known as the holy medicine for night sweat. By bibliometrics， the authors collected the ancient books on Danggui Liuhuangtang and screened out 269 valid data， involving 156 ancient books of traditional Chinese medicine. The analysis on the historical origin， disease syndromes， pathogenesis， composition， dosage， preparation， usage， and processing of Danggui Liuhuangtang found that this famous classical formula originated from Secret Book of the Orchid Chamber （《兰室秘藏》） written by LI Dongyuan， and is composed of Angelicae Sinensis Radix， Rehmanniae Radix， Rehmanniae Radix Praeparata， Phellodendri Chinensis Cortex， Scutellariae Radix， Coptidis Rhizoma and Astragali Radix. It has the functions of nourishing Yin， reducing fire， consolidating exterior and stopping sweating， and mainly treats night sweat due to Yin deficiency and fire exuberance. In the later generations， disease syndromes are mostly treated based on LI Dongyuan's theory， and have expanded to more than 30 kinds （339 in total）， among which night sweat （208） was the most， accounting for 61.36% of the total disease syndromes， followed by spontaneous sweating （38）， accounting for 11.21%. Additionally， it was found that Danggui Liuhuangtang was widely used in modern clinical practice for various disease syndromes. Among them， endocrine disease （77， 28.21%） was predominant， followed by gynecological disease （48， 17.58%）， and pediatric disease （24， 8.79%）. Although Danggui Liuhuangtang treats many disease syndromes， their pathogenesis was always yin deficiency and fire exuberance. Through the systematic excavation of the ancient books on Danggui Liuhuangtang and the analysis of its modern clinical application， this paper probed into the historical evolution and confirmed the key information of the formula， providing detailed literature basis for the research and development application of famous classical formulas.
RESUMO
Shengyang Yiweitang is one of the first 100 classical prescriptions published by the National Administration of Traditional Chinese Medicine. It originated from the Clarifying Doubts about Damage from Internal and External Causes by physician LI Dongyuan of Jin dynasty， and is composed of Astragali Radix， Ginseng Radix et Rhizoma， Glycyrrhizae Radix et Rhizoma， Atractylodis Macrocephalae Rhizoma， Poria， Pinelliae Rhizoma， Citri Reticulatae Pericarpium， Angelicae Pubescentis Radix， Saposhnikoviae Radix， Notopterygii Rhizoma et Radix， Bupleuri Radix， Paeoniae Radix Alba， Alismatis Rhizoma， and Coptidis Rhizoma. With the effects of replenishing Qi， promoting Yang， clearing heat and removing dampness， Shengyang Yiweitang is used to treat spleen-stomach weakness and dampness-heat accumulation syndrome. Using bibliometrics， the authors systematically sorted out the source，composition， dosage， preparation， efficacy， indications， principle of composition， origin and processing of drugs，and modern clinical application of the prescription， and explored its history and key information. Additionally， it was found that Shengyang Yiweitang was widely used in modern clinical practice and was suitable for multisystem diseases， of which digestive system （264） was the most common， accounting for 41.71%， followed by urogenital system （57， 9.00%） and nervous system （48， 7.58%）. Although the treatment scope was wide， the pathogenesis of the diseases in traditional Chinese medicine belongs to "spleen-stomach weakness"， which fully reflected Li's academic thought of "internal injury of spleen and stomach leads to various diseases". The key information of Shengyang Yiweitang was determined by summarizing the relevant ancient books and modern literature， so as to provide accurate reference for its rational clinical application and further research and development.

RESUMO
Objective To investigate the effects of microRNA-18a (miR-18a) on migration and invasion of hepatocellular carcinoma (HCC) cells, and its possible mechanism associated with Dicer l.Methods HepG2 and HepG2.2.15 cells were transfected with miR-18a inhibitor using Lipofectamine. Cell invasion was evaluated by transwell invasion assay, and cell migration was detected by transwell migration and wound-healing assays. Moreover, luciferase reporter assay was used to identify whether Dicer expression was regulated by miR-18a. Real-time RT-PCR and western blot were performed to analyze Dicer 1 expression. In addition, a functional restoration assay was performed to investigate whether miR-18a promotes HCC cell migration and invasion by directly targeting Dicer 1.Results miR-18a inhibitor can suppress the migration and invasion of HCC cells. Furthermore, suppression of Dicer l expression by small interfering RNA essentially abolished the inhibition of cell migration and invasion induced by miR-18a inhibitor, restorating these activities to levels similar to the parental HCC cells. Interestingly, suppression of miR-18a in HCC cells resulted in enhanced expression of Dicer l. In addition, the results of a luciferase assay demonstrated targeted regulation of Dicer l by miR-18a.Conclusion Our findings suggest that miR-18a promotes migration and invasion of HCC cells by inhibiting Dicer l expression.
