[Study on drug properties and syndrome-symptom-formula-herb network of traditional Chinese medicine in treatment of effort angina pectoris based on data visualization].
This article aims to explore drug properties and syndrome-symptom-formula-herb network of traditional Chinese medicine(TCM) in the treatment of effort angina pectoris based on data visualization, and provide useful references for clinical diagnosis and treatment. Literatures about TCM formula for effort angina pectoris from databases of CNKI, WanFang, VIP, and CBM were retrieved from the database-building to August 31, 2019. The name of syndromes, symptoms, formulas, and herbs were standardized, and the corresponding databases were established. ⋯ The high-frequency syndromes of this disease were Qi deficiency and blood stasis, Qi stagnation and blood stasis, heart blood stasis, and turbid phlegm and blood stasis, and its high-frequency symptoms were chest tightness, chest pain, palpitation, shortness of breath, fatigue, dark purple tongue, spontaneous sweating, and abundant phlegm. High-frequency core formulas of this disease included Xuefu Zhuyu Decoction, Gualou Xiebai Banxia Decoction, Danshen Decoction, Taohong Siwu Decoction, Shengmai Powder, Buyang Huanwu Decoction and Zhigancao Decoction, and their core herbs included Salviae Miltiorrhizae Radix et Rhizoma, Astragali Radix, Chuanxiong Rhizoma, Ginseng Radix et Rhizoma, Trichosanthis Fructus, Allium Macrostemonis Bulbus, Notoginseng Radix et Rhizoma, Persicae Semen, Carthami Flos, Atractylodis Macrocephalae Rhizoma, Angelicae Sinensis Radix, Paeoniae Radix Rubra, Poria, Pinelliae Rhizoma Praeparatum. Drug properties and syndrome-symptom-formula-herb networks of TCM in the treatment of effort angina pectoris can realize data visualization, objectively reflect the clinical syndrome differentiation and rule of medication, and provide reference for clinical diagnosis and treatment.

[Molecular mechanism of Puerariae Lobatae Radix in treatment of hepatocellular carcinoma based on network pharmacology].
To investigate the potential mechanism of Puerariae Lobatae Radix in the treatment of hepatocellular carcinoma by network pharmacology and in vitro cell experiment. The main active components of Puerariae Lobatae Radix and their predicted targets were obtained from TCMSP, and the disease targets were obtained from GeneCards database. The disease and drug prediction targets were intersected to select the common potential therapeutic targets. ⋯ In vitro cell experiments confirmed that puerarin has a significantly inhibitory effect on the proliferation of human hepatocellular carcinoma cells. Western blot results showed that puerarin could increase the phosphorylation of PTEN in human hepatocellular carcinoma cells through the PTEN/Akt/GSK3β signaling pathway, and the phosphorylation level of its downstream Akt decreased. This series of studies confirm that puerarin can treat hepatocellular carcinoma by blocking PTEN/Akt/GSK3β cellular signaling pathway, so as to provide ideas for subsequent studies for the molecular mechanism of puerarin in the treatment of liver cancer.

[Product improvement and secondary development of Pudilan Xiaoyan Oral Liquid based on clinical medication].
Pudilan Xiaoyan Oral Liquid is widely used in clinical applications, with safe and effective results. Its coverage rate in the national first, second and third grade hospitals is as high as 71%. In this study, we analyzed and summarized the research progress on the material basis, quality control, production process and clinical medication of Pudilan Xiaoyan Oral Liquid based on the clinical diseases(parotitis, tonsillitis, pharyngitis), and deeply explored the intrinsic quality improvement and secondary development of Pudilan product. ⋯ Through these techno-logies, it would be more specific, scientific and effective to carry out process optimization of each link and multidimensional quality control of the whole process. The dosage and oral compliance for special patients(children) were explored, providing a reference for clinical pediatric medication of Pudilan Xiaoyan Oral Liquid. Simultaneously, it is helpful to expand the application market by developing Pudilan daily chemical products, and promote the traditional Chinese medicine products in terms of curative effect and daily life.

[Investigation of active components and mechanism of Pudilan Xiaoyan Oral Liquid based on network pharmacology].
To investigate the active components/ingredients of Pudilan Xiaoyan Oral Liquid based on the network pharmacology technology, and analyze the network data of its potential targets and mechanisms. The active ingredient screening, protein interaction analysis and pathway annotation were used to further optimize its active components and potential targets, and clarify the pharmacodynamic substance basis and mechanism of Pudilan Xiaoyan Oral Liquid. Through this technique, we screened out 41 active ingredients in Pudilan Xiaoyan Oral Liquid, mainly including 16 alkaloid components, 13 organic acid components, 11 flavonoid components and 1 coumarin component such as chicoric acid, chlorogenic acid, oroxindin, rutin, corynoline, and esculetin. ⋯ A total of 22 disease signaling pathways are involved, including 4 pathways closely related to inflammation. The IL-17 signaling pathway had the highest D(degree) value and may be most closely related to inflammatory diseases. Through network data excavating, we initially explored the main active components/ingredients of Pudilan Xiaoyan Oral Liquid, clarified the pharmacodynamic basis of Pudilan Xiaoyan Oral Liquid treatment-related diseases and its key mechanism of action in this study, hoping to provide a theoretical basis for clinical research, and at the same time, lay the foundation for deep research and promotion of Pudilan Xiaoyan Oral Liquid product.

[Improvement of compliance of Pudilan Xiaoyan Oral Liquid based on comprehensive analysis of bad taste of traditional Chinese medicine oral liquid preparation].
From "good efficacy with a bad taste" to "good efficacy with no bitterness" and then to "good efficacy with a good taste" is the only way to develop oral liquid preparations of traditional Chinese medicine, and "good medicine is beneficial to disease" is the only way for the development of oral liquid preparations of traditional Chinese medicine. Based on the analysis of the causes, the sources of bitterness, the formation principles and their solutions of traditional Chinese medicine oral liquid preparations, we explored the causes of the bad taste and the material basis of bitterness of Pudilan Xiaoyan Oral Liquid, and applied the solutions in improving the taste of Pudilan products. The overall taste of Pudilan Xiaoyan Oral Liquid was improved by modifying the original product taste, enhancing the process and changing the dosage form, which improves the compliance of the patients who take the medicine, and better serve the clinical medication.
