: Plants have always been an important source of medicines for humans, and licorice is a very significant herb in the development of humans. As a traditional herb, it is widely cultivated in China, Japan, Russia, Spain and India. With the development of organic chemistry and biochemistry, various chemical ingredients extracted from licorice have been studied and identified. Among them, many chemical components were considered to have strong pharmacological activities, such as anti-inflammatory, anti-ulcer, antibacterial, anticancer and so on. Based on those reports, licorice has attracted the attention of many researchers in recent years, and they are devoted to discovering the active ingredients and mechanism of action of active compounds. Licorice flavonoids are one of the main extracts of licorice root and stem and have many potential biological properties. This paper aims to summarize the four kinds of licorice flavonoids, including liquiritigenin, isoliquiritigenin, licochalcone (including licochalcone A and licochalcone B) and glabridin, about their biological activities of anti-inflammatory, anticancer, antibacterial.

Objectives Cinnamomi ramulus (called Guizhi in Chinese) is a traditional medicine used to treat gastrointestinal dysfunction, cancer, arthritis, osteoporosis, spleen deficiency, Alzheimer's disease and obesity. This review aimed to provide a systematic summary on the geographical distribution, botany, traditional application, phytochemistry, pharmacology, pharmacokinetics, toxicology and other aspects of Cinnamomi ramulus. Key finding So far, more than 121 chemical compounds have been isolated from Cinnamomi ramulus, including volatile oil, organic acids, triterpenoid saponins, coumarins, tannins, flavonoids and flavonoid glycosides, steroids and polysaccharides. This paper reviews the pharmacological effects of Cinnamomi ramulus on antibacterial, anti-inflammatory, antiviral, antitumour, antipyretic and analgesic, antidiabetic and antiplatelet aggregation effects. Furthermore, the present review also indicates that Cinnamomi ramulus has the potential to develop into drugs for treating various diseases with high efficacy and low toxicity. Summary The convictive evidence from modern pharmacology research supports the traditional application of Cinnamomi ramulus. However, further studies on the structure-activity relationship of some of the isolated compounds may improve their biological potency. More toxicological studies will also contribute to the progress of clinical trial studies.

Alternative splicing (AS) provides the primary mechanism for producing protein diversity. There is growing evidence that AS is involved in the development and progression of cancers. The rapid accumulation of high‐throughput sequencing technologies and clinical data sets offers an opportunity to systematically profile the relationship between mRNA variants and clinical outcomes. However, there is a lack of systematic analysis of AS in prostate cancer: Download RNA‐seq data and clinical information from The Cancer Genome Atlas (TCGA) data portal. Evaluate RNA splicing patterns by SpliceSeq and calculate splicing percentage (PSI) values. Different expressions were identified as differently expressed AS events (DEAs) based on PSI values. Bioinformatics methods were used for further analysis of DEAs and their splicing networks. Kaplan‐Meier, Cox proportional regression, and unsupervised cluster analysis were used to assess the correlation between DEAs and clinical characteristics. In total, 43 834 AS events were identified, of which 1628 AS events were differentially expressed. The parental genes of these DEAs played a significant role in the regulation of prostate cancer‐related processes. In total, 226 DEAs events were found to be associated with disease‐free survival. Four clusters of molecules with different survival modes were revealed by unsupervised cluster analysis of DEAs. AS events may be important determinants of prognosis and bio‐modulation in prostate cancer. In this study, we established strong prognostic predictors, discovered a splicing network that may be a potential mechanism, and provided further validated therapeutic targets.
