Abstract Scutellaria baicalensis Georgi. (SB) is a common heat-clearing medicine in traditional Chinese medicine (TCM). It has been used for thousands of years in China and its neighboring countries. Clinically, it is mostly used to treat diseases such as cold and cough. SB has different harvesting periods and processed products for different clinical symptoms. Botanical researches proved that SB included in the Chinese Pharmacopoeia (1st, 2020) was consistent with the medicinal SB described in ancient books. Modern phytochemical analysis had found that SB contains hundreds of active ingredients, of which flavonoids are its major components. These chemical components are the material basis for SB to exert pharmacological effects. Pharmacological studies had shown that SB has a wide range of pharmacological activities such as antiinflammatory, antibacterial, antiviral, anticancer, liver protection, etc. The active ingredients of SB were mostly distributed in liver and kidney, and couldn't be absorbed into brain via oral absorption. SB’s toxicity was mostly manifested in liver fibrosis and allergic reactions, mainly caused by baicalin. The non-medicinal application prospects of SB were broad, such as antibacterial plastics, UV-resistant silk, animal feed, etc. In response to the Coronavirus Disease In 2019 (COVID-19), based on the network pharmacology research, SB’s active ingredients may have potential therapeutic effects, such as baicalin and baicalein. Therefore, the exact therapeutic effects are still need to be determined in clinical trials. SB has been reviewed in the past 2 years, but the content of these articles were not comprehensive and accurate. In view of the above, we made a comprehensive overview of the research progress of SB, and expect to provide ideas for the follow-up study of SB.

Abstract BACKGROUND Mycoplasma pneumoniae pneumonia (MPP) is an acute respiratory infectious pneumonia with pulmonary interstitial fibrosis. TGF-β1 is well accepted as the central mediator for fibrosis which promotes the formation of tissue fibrosis factor. Qinbaiqingfei pellet (Qinbai) has already been approved as the first effective new traditional Chinese medicine which can delay activities of Mycoplasma pneumoniae (M.pneumoniae) and protect lung epithelial cells in clinical trials. However, the mechanism of Qinbai inhibiting the expression of TGF-β1 is still unclear. METHODS The Chinese herbs in Qinbai were screened by surface plasmon resonance (SPR) and it was deteimined that Scutellaria baicalensis extracts in Qinbai showed the best binding with TGF-β1. Then the active ingredient whicn can be bound with TGF-β1 protein in the solution of Qinbai and Scutellaria baicalensis was isolated and analyzed by UPLC-Q-TOF-MS, which proved the active ingredient was Wogonoside. The affinity constant of Wogonoside and TGF-β1 protein was measured by SPR affinity analysis. A549 cells infected with M.pneumoniae were intervened by Wogonoside, and then the expression of TGF-β1 and Smad3 in A549 cells were analyzed by PCR and western blotting. RESULTS The results showed the bound effect of Scutellaria baicalensis and TGF-β1 was effective. The active ingredients which can be bound with TGF-β1 in the solution of Scutellaria baicalensis and Qinbai were obtained and analyzed to investigate the mechanism of Qinbai inhibiting the expression of TGF-β1. UPLC-Q-TOF-MS results showed that the active ingredients was Wogonoside. SPR affinity analysis showed that the affinity constant was 21.71 µM. Pharmacological experiments revealed that Wogonoside strongly inhibited the expression of TGF-β1 and Smad3 in A549 cells infected by M.pneumoniae. CONCLUSION Wogonoside in Qinbai can be bound with TGF-β1 and down-regulate the expression of lung fibrosis factors TGF-β1 and Smad3. The finding may improve our understanding the molecular mechanism of Qinbai mediating MPP and provide new sights into the future pharmacological investigation of Qinbai.

Prediction and reconstruction of metabolic pathways play significant roles in many fields such as genetic engineering, metabolic engineering, drug discovery, and are becoming the most active research topics in synthetic biology. With the increase of related data and with the development of machine learning techniques, there have many machine leaning based methods been proposed for prediction or reconstruction of metabolic pathways. Machine learning techniques are showing state-of-the-art performance to handle the rapidly increasing volume of data in synthetic biology. To support researchers in this field, we briefly review the research progress of metabolic pathway reconstruction and prediction based on machine learning. Some challenging issues in the reconstruction of metabolic pathways are also discussed in this paper.

Abstract: The continuous increase in the incidence rate of various fatal malignant tumors in the recent years warrants an imperative search for medications or drugs with obvious anti-tumor effects and reliable curative effects. Previous studies have found that Curcuma zedoaria and its active ingredients, such as turmeric oil, curcumol, and ?-elemene, have obvious anti-tumor effects, and they do not have the adverse reactions and side effects seen in the anti-tumor drugs of Western medicine. Based on the review and inductive analysis of related literature, we summarize in the present article the results of some researchers who investigated the anti-tumor effects of Curcuma zedoaria and its active ingredients through the immune regulation mechanism.
