Schisandra is the mature fruit of Schisandra chinensis(known as "north Schisandra") or S. shenanthera(known as "south Schisandra"). Ivacaftor cost S. chinensis contains a variety of lignans, volatile oils, polysaccharides, organic acids and other chemical constituents; among them, lignans are recognized as the characteristic active components. Clinical studies have found that Schisandra and Schisandra-related products have a better effect in the prevention and treatment of viral hepatitis, drug-induced liver injury, liver cirrhosis, liver failure and other liver diseases. Modern pharmacological studies have demonstrated that Schisandra has a variety of pharmacological activities, such as anti-inflammation, antioxidation, anticancer, regulation of nuclear receptor, antivirus, regulation of cytochrome P450 enzyme, inhibition of liver cell apoptosis and promotion of liver regeneration. This paper reviews the studies about the applications and mechanism of Schisandra in the prevention and treatment of liver diseases, in the expectation of providing guidance for the development of hepatoprotective drugs from Schisandra and the clinical applications of Schisandra-related products.At present, most of Chinese patent medicines have problems, such as weak scientific basis, unclear clinical value evaluation, etc., which lead to the lack of sufficient evidence for the entry into the essential medicine list, medical insurance catalog and other important health resource allocation tools. This has a negative impact on the development of traditional Chinese medicine. It is urgent to establish a comprehensive evaluation methodology system of Chinese patent medicine in China. There are at least three reasons including producing evidence for clinical rational use scientifically, developing an objective and transparent selecting strategy, eventuating and highlighting its clinical value. The process and method of health technology assessment(HTA) can provide reference for the establishment of comprehensive evaluation method of Chinese patent medicine. However, HTA is rarely carried out in the field of traditional Chinese medicine. The latest domestic and international research showed that HTA combined with multi-criteria decision analysis(MCDA) can increase the transparency of decision-making and improve the quality of decision-making. The combined two formed the EVIDEM framework, which is conducive to drug selection and its clinical use. In this paper, the EVIDEM framework was introduced to establish the methodology framework of the comprehensive clinical evaluation system of Chinese patent medicine. A preliminary research idea has been put forward. In the future, we can establish a set of comprehensive clinical evaluation methods for Chinese patent medicine in cooperation with relevant national drug decision-making departments and management departments. It is believed that such cooperation could promote the full implementation of the re-evaluation for Chinese patent medicine.The consistency of quality on Chinese patent drugs is a hotspot and difficulty in the control of traditional Chinese medicine preparations, and has become one of the bottlenecks restricting its internationalization. Based on the analysis of current studies on quality and problems of Chinese patent drugs, this paper explored relevant methods of quality evaluation on Chinese patent drugs and possible factors affecting the consistency of quality in the pharmaceutical cycle by consulting relevant literatures about quality evaluation methods and consistency control techniques of large-scale Chinese patent drugs. And it put forward the evaluation system on high-quality Chinese patent drugs with "consistency" as the core, so as to promote the overall improvement of the quality of Chinese patent drugs, guide the rational price of Chinese patent drugs of the same species, and provide a new reference model for the quality evaluation of Chinese patent drug.This study is to explore the effect of Qingfei Paidu Decoction(QPD) on the host metabolism and gut microbiome of rats with metabolomics and 16 S rDNA sequencing. Based on 16 S rDNA sequencing of gut microbiome and metabolomics(GC-MS and LC-MS/MS), we systematically studied the serum metabolites profile and gut microbiota composition of rats treated with QPD for continued 5 days by oral gavage. A total of 23 and 43 differential metabolites were identified based on QPD with GC-MS and LC-MS/MS, respectively. The involved metabolic pathways of these differential metabolites included glycerophospholipid metabolism, linoleic acid metabolism, TCA cycle and pyruvate metabolism. Meanwhile, we found that QPD significantly regulated the composition of gut microbiota in rats, such as enriched Romboutsia, Turicibacter, and Clostridium_sensu_stricto_1, and decreased norank_f_Lachnospiraceae. Our current study indicated that short-term intervention of QPD could significantly regulate the host metabolism and gut microbiota composition of rats dose-dependently, suggesting that the clinical efficacy of QPD may be related with the regulation on host metabolism and gut microbiome.The aim of this paper was to investigate the effect of Schizonepetae Herba and Saposhnikoviae Radix(wind medicine) on the expression of AQP4 and AQP8 in colonic mucosa in rats with ulcerative colitis(UC). A total of 35 healthy SD male rats were randomly divided into normal group(gavaged with normal saline), DSS model group, as well as low, middle, and high dose wind medicine groups(Schizonepeta and Saposhnikovia 1∶1, gavaged at dosages of 6, 12, and 24 g·kg~(-1)·d~(-1)), with 7 in each group. UC rat model was established by free drinking of 3% dextran sulphate sodium(DSS) solution for 10 days. At the end of the 10 th day after the treatment, mice were put to death to collect colonic mucosa. The length of colon was measured; the colonic mucosal injury index(CMDI) and pathological changes of colon were observed. ELISA method was used for measuring the content of serum IL-1, IL-8, and immunohistochemical method was used to measure AQP4, AQP8 protein expressions in colon mucosa. The expressions of AQP4, AQP8 mRNA were measured by Real-time PCR.
