Objective To develop a method for the determination of Hesperidin,magnolol from "He-Wei-Yin" Mixture,and for its quality control,high-performance liquid chromatography (HPLC) is used.Method After plenty of study about the condition,the final result choosed was as following:an analytical column of HypersiC18(200mm?4.6mm,5?m ) maked by HP was utilized. The column number was 13164421196.The mobile phase was adapted gradient with methanol-1% acetum solution,according to the following profile:0～30min,methanol concentration from 30% to 70%;30～40min,from 70% to 80%;40～50min,from 80% to 30%. The flow rate was 1.0ml/min with the column kept at ambient temperature. All the components had come out in 45 min with the detection wavelength at 294nm. It followed the order of Heperidin,Magnolol according to the retention times in the chromatography.Results In the result,the regression equations were as following:Hesperidin was Y=139.718X+4.511 with a good linearity (r=0.99994). Magnolol was Y=1456.342X+106.506 with a good linearity (r=0.99957) between the peak area and the mass of the standard.The recoveries of the method were as following:in the "He-Wei-Yin" Mixture,for hesperidin,precision of the method RSD=1.87%(n=5),recovery of the method 96.53%(RSD=3.36%,n=3);for Magnolol,precision of the method RSD = 0.34% (n=5); recovery of themethod 93.17%(RSD=4.69%,n=3).At the same condition as above,the determination of content was carried out for six different dose and batch No.Conclusion The method is simple and reliable,easy to operate,suitable for the quality control of Hesperidin and Magnolol in "He-Wei-Yin" Mixture.

Refractory alopecia is one of the most intractable skin diseases.Through giving full play to the characteristics of holism and determination of treatment based on syndrome differentiation,basing on the whole,adjusting yin and yang,observing the pathogenesis in clinic and being well informed about the nomalities and changes of the disease,Professor BAI Chang-chuan has greatly broadened the clinical thinking and practice of TCM in treating alopecia.

ObjectiveTo investigate the mechanism of action of Xiaoyao powder combined with Sijunzi decoction, Artemisia capillaris Thunb. decoction, Longdan Xiegan decoction combined with Xiayuxue decoction, Wupi decoction combined with Sijunzi decoction, and Yiguan decoction in the treatment of hepatocellular carcinoma (HCC) based on network pharmacology and molecular docking. MethodsDatabases including TCMSP, TCMID, BATMAN-TCM, and TCM-MESH were used to screen out effective components and predict their targets, and databases including TTD, Drugbank, Disgenet, Liverome, OncoDB.HCC, and GEO were used to investigate HCC-related targets. The drug and disease targets were mapped to obtain the intersecting targets, and the visualization software Cytoscape 3.7.1 was used to construct the core component-intersecting target network and the protein-protein interaction (PPI) network. The core components and key genes were screened out and a survival analysis was performed in the GEPIA database. The active components and key genes screened out were imported into the DockThor online website for molecular docking. In addition, David database was used to perform gene ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis of the intersecting targets. ResultsThe analysis showed that 110, 19, 154, 121, and 51 active components, respectively, were obtained for the above five classic prescriptions, and the numbers of drug targets were 7426, 1435, 9544, 6619, and 2427, respectively. Finally 4001 HCC disease targets were screened out. There were 260, 169, 276, 242, and 192 intersecting targets, respectively, between the five prescriptions and the HCC disease targets, and the survival analysis on the GEPIA online website obtained the common hub genes of PIK3CA, SRC, MAPK1, MAPK3 (all P＜0.05) and AKT1 (P＞0.05). Quercetin was the common active component of the five prescriptions, and isobavachin and Kanzonol W were the common active components of Xiaoyao powder combined with Sijunzi decoction, Longdan Xiegan decoction combined with Xiayuxue decoction, and Wupi decoction combined with Sijunzi decoction; the results of molecular docking showed that the above three components had a strong ability of binding to PIK3CA and SRC. GO enrichment analysis showed that these targets were involved in various biological processes including drug response, protein phosphorylation, inflammatory response, and angiogenesis, and KEGG enrichment analysis showed that the common pathways involved were cancer pathway, PI3K-Akt signaling pathway, MAPK signaling pathway, Ras signaling pathway, HIF-1 signaling pathway, hepatitis B pathway, and hepatitis C pathway. ConclusionQuercetin, isoflavone, and Kanzonol W have the potential mechanism of action involving multiple targets and pathways in the treatment of HCC.

Autophagy has become a research hotspot in the prevention and treatment of tumor in recent years. With the help of the bidirectional regulatory effect of autophagy, it can not only provide energy and a stable internal environment for normal and tumor cells by clearing misfolded proteins and damaged organelles in cells, but also induce autophagic death of tumor cells. Traditional Chinese medicine has advantages over Western medicine in better mediating autophagy to inhibit tumor development and progression, with the features of low toxicity, multiple targets, and multiple pathways. With an increasing number of studies on autophagy in traditional Chinese medicine, this article reviews the research advances in the effect of traditional Chinese medicine in autophagy in liver cancer in the past 10 years and explores and analyzes existing problems, hoping to provide a reference and new ideas for subsequent research on liver cancer.
